TECHNICAL FIELD
The present disclosure relates to a connector and a connector assembly.
BACKGROUND
Conventionally, vehicles such as a hybrid car and an electric car are provided with onboard equipment including a high pressure battery and an inverter. Onboard equipment is connected to another via a wire harness and a connector assembly. A connector assembly includes a counterpart connector and a connector that can be connected to the counterpart connector by a relative movement in a first direction along a first axis. The counterpart connector includes a counterpart terminal and a counterpart housing. The connector includes a terminal electrically connectable to the counterpart terminal and a connector housing that can be fit to the counterpart housing. Such a connector thus includes an arm that can pivot with respect to a connector housing such that the arm supports an operation of fitting to a counterpart housing (for example, see Patent Document 1). The connector includes a pair of arms. The pair of arms has locking portions that are engaged with each other by the elasticity of the arms before the connector housing is fit onto the counterpart housing. The pair of arms is temporarily locked at an initial position by the engagement of the locking portions.

SUMMARY OF THE INVENTION
Problems to be Solved
Although the connector configured thus has the arms temporarily locked by the locking portions at the initial position, the locking portions engaged by the elasticity of the arms have only a small engaging force. Thus, the temporarily locked arms may be easily disengaged from each other by, for example, an external force such as vibrations during transport. Furthermore, if the arms move from the initial position before the connector housing is fit onto the counterpart housing, problems may arise, for example, the connector housing cannot be fit onto the counterpart housing.
The present disclosure has been devised to solve the problem. An object of the present disclosure is to provide a connector and a connector assembly that are capable of normally fitting a connector housing onto a counterpart housing with stability.

DETAILED DESCRIPTION TO EXECUTE THE INVENTION
Description of Embodiment of Present Disclosure
An embodiment of the present disclosure will be first described in list form.
- [1] A connector according to the present disclosure is a connector connectable to a counterpart connector by a relative movement in a first direction along a first axis, the counterpart connector including a counterpart terminal and a counterpart housing, the connector including: a terminal connectable to the counterpart terminal; a connector housing that accommodates the terminal and is allowed to be fit onto the counterpart housing; a lever that is mounted on the connector housing and is movable relative to the connector housing along the first axis in a range from a first position to a second position separated from the first position in the first direction; and an arm that is drivingly coupled to the lever and moves in a direction different from the moving direction of the lever according to a relative movement of the lever, wherein the connector housing has a slit extending along the first axis and is configured to approach a state of fit to the counterpart housing as the lever moves from the first position to the second position, the arm has a locking protrusion that is fit into the slit so as to regulate a movement of the arm in a state in which the lever is located at the first position, the lever has an elastic piece that presses the arm in a direction that fits the locking protrusion into the slit, and the locking protrusion is pressed out of the slit by the extruding portion of the counterpart housing in an initial state of fit into the connector housing.
With this configuration, in a state in which the locking protrusion is not pressed out of the slit by the extruding portion of the counterpart housing in an initial state of fit into the connector housing, the arm is pressed in a direction along which the locking protrusion is fit into the slit by the elastic piece of the lever. Thus, a movement of the arm is regulated by fitting the locking protrusion into the slit. Accordingly, a movement of the lever drivingly coupled to the arm is also regulated. Hence, for example, movements of the arm and the lever from the initial position are suppressed before the connector housing is fit onto the counterpart housing. This can avoid problems caused by movements of the arm and the lever from the initial position, thereby normally fitting the connector housing onto the counterpart housing with stability. Moreover, for example, wrong assembly of the connector housing to a counterpart housing other than the counterpart housing having the extruding portion is suppressed. Thereafter, when the locking protrusion is pressed out of the slit by the extruding portion of the counterpart housing in an initial fit state, the arm is allowed to move. Furthermore, when the lever is moved from the first position to the second position along the first axis, the connector housing is fit into the counterpart housing.
- [2] It is preferable that the arm has an engaging portion that is allowed to be engaged with an engaged portion of the counterpart housing, and the connector housing is configured to move relative to the counterpart housing and approach a state of fit to the counterpart housing as the engaging portion in engagement with the engaged portion moves according to a movement of the lever from the first position to the second position.
With this configuration, the arm moves as the lever moves from the first position to the second position, and the engaging portion in engagement with the engaged portion of the counterpart housing also moves, so that the connector housing can be brought close to a state of fit to the counterpart housing.
- [3] The engaging portion is preferably engaged with the engaged portion in the initial fit state.
With this configuration, in the initial fit state of the connector housing and the counterpart housing, the arm is allowed to move and the engaging portion is engaged with the engaged portion. Thus, the connector housing and the counterpart housing can be normally fit to each other by operating the lever. Specifically, in a configuration in which the engaging portion is likely to be disengaged from the engaged portion while the arm is allowed to move in an initial fit state, the lever may be erroneously operated in the disengaged state. The present embodiment can avoid such a problem. Thus, the connector housing and the counterpart housing can be normally fit to each other with higher stability.
- [4] The slit preferably allows the engaged portion to move along the first axis while protruding the engaged portion toward the engaging portion.
With this configuration, the slit has the function of receiving the locking protrusion capable of regulating a movement of the arm and introducing the extruding portion that presses the locking protrusion and the function of moving the engaged portion along the first axis while protruding the engaged portion toward the engaging portion. Thus, for example, as compared with a configuration in which the connector housing is provided with two slits having two different functions, the configuration of the connector housing is simplified.
- [5] The locking protrusion preferably includes a locking face that comes into contact with the inner wall surface of the slit to prevent component forces from being generated in a direction against a pressing force of the elastic piece when the lever starts moving from the first position to the second position with the locking protrusion fit into the slit.
With this configuration, even when the lever starts moving from the first position to the second position with the locking protrusion fit into the slit, the locking face of the locking protrusion comes into contact with the inner wall surface of the slit to prevent component forces from being generated in a direction against the pressing force of the elastic piece. Thus, a movement of the arm from the initial position can be firmly suppressed.
- [6] It is preferable that the connector housing has a step on a surface facing the arm, and the locking protrusion has a first inclined face that generates component forces for sliding the lever over the step when the lever moves from the second position side to the first position side.
With this configuration, when the lever moves from second position side to the first position side, the first inclined face of the locking protrusion generates component forces that allow the lever to slide over the step. Thus, the locking protrusion can smoothly slide over the step, thereby reaching the slit without any interruption.
- [7] The locking protrusion preferably has a second inclined face that comes into contact with the extruding portion so as to generate component forces in a direction of extrusion from the slit when approaching the initial fit state.
With this configuration, when the connector housing approaches an initial state of fit to the counterpart housing, component forces are generated in the direction of extrusion from the slit by the second inclined face of the locking protrusion that comes into contact with the extruding portion. Thus, the locking protrusion is smoothly pressed out of the slit.
- [8] It is preferable that the elastic piece presses the arm in a state in which the lever is located at the first position, and the elastic piece does not press the arm in a state in which the lever is not located at the first position.
With this configuration, the elastic piece does not press the arm in a state in which the lever is not located at the first position, thereby suppressing, for example, an excessive press on the arm into contact with the connector housing when the arm moves. Thus, for example, a sliding resistance against a movement of the arm can be suppressed. Moreover, for example, wear of the arm and the connector housing can be suppressed.
- [9] The elastic piece preferably has a third inclined face that generates component forces for sliding the lever onto the arm when the lever moves from the second position side to the first position.
With this configuration, when the lever moves from second position side to the first position, the third inclined face of the elastic piece generates component forces for sliding the lever onto the arm. Thus, the elastic piece can smoothly slide onto the arm, thereby pressing the arm without any interruption.
- [10] A connector assembly according to the present disclosure includes: the connector and the counterpart connector.
With this configuration, the connector housing can be normally fit onto the counterpart housing with stability in the connector assembly.

In the drawings, some configurations may be exaggerated or simplified for convenience of explanation. Moreover, the scale ratios of parts may vary among the drawings. “Parallel,” “orthogonal,” and “perfect circle” in the present specification mean nearly parallel, nearly orthogonal, and a nearly perfect circle within the scope of the working-effect of the present embodiment as well as strictly parallel, strictly orthogonal, and a strictly perfect circle. The present invention is not limited to these illustrations and is intended to include meanings equivalent to the claims and all changes in the scope.
Configuration of Connector Assembly 11
As illustrated in FIG. 1, a connector assembly 11 includes a counterpart connector 21 and a connector 31 that can be connected to the counterpart connector 21 by a relative movement in a first direction X1 along a first axis X. The connector assembly 11 is provided in a vehicle. For example, a vehicle includes onboard equipment including a high pressure battery and an inverter, which are connected to each other via wire harnesses WH. The connector assembly 11 is provided as, for example, a component for connecting the onboard equipment and the wire harnesses WH. FIG. 1 illustrates the first axis X, a second axis Y orthogonal to the first axis X, and a third axis Z orthogonal to the first axis X and the second axis Y. Moreover, FIG. 1 illustrates the first direction X1 that is one direction along the first axis X and a first opposite direction X2 that is the other direction along the first axis X and opposite to the first direction X1. FIG. 1 also illustrates a second direction Y1 that is one direction along the second axis Y and a second opposite direction Y2 that is the other direction along the second axis Y and opposite to the second direction Y1.
Configuration of Counterpart Connector 21
The counterpart connector 21 includes counterpart terminals 22 and a counterpart housing 23 that accommodates the counterpart terminals 22. The counterpart terminals 22 extend along the first axis X. The two counterpart terminals 22 are provided in parallel along the second axis Y. The counterpart terminal 22 has one end connected to, for example, the connecting terminal of onboard equipment in the first direction X1. The counterpart housing 23 is configured with an insulating resin material. The counterpart housing 23 is shaped like a square pillar opened in the first opposite direction X2 opposite to the first direction X1. A wall portion 23a extending along the second axis Y on the counterpart housing 23 has a protruding extension 24 that protrudes outward along the third axis Z and extends along the first axis X. Furthermore, an engaged portion 25 protruding along the third axis Z is provided on the side of the first opposite direction X2 of the protruding extension 24. The engaged portion 25 is shaped like a circular cylinder. Moreover, a portion ahead of the engaged portion 25 in the first opposite direction X2 on the protruding extension 24 constitutes an extruding portion 26. On the counterpart housing 23, one end on the side of the first direction X1 is fixed to, for example, the housing of onboard equipment.
Configuration of Connector 31
As illustrated in FIGS. 1 and 2, the connector 31 includes terminals 32, a connector housing 33 accommodating the terminals 32, and a lever 34, an arm 35, and a lock member 36 that are attached to the connector housing 33.
Configuration of Terminal 32
As illustrated in FIG. 1, the terminals 32 extend along the first axis X. The two terminals 32 are provided in parallel along the second axis Y and are disposed to be electrically connectable to the respective counterpart terminals 22. On the terminal 32, one end on the side of the first opposite direction X2 is connected to the core wire of the wire harness WH.
Configuration of Connector Housing 33
The connector housing 33 is configured with an insulating resin material.
As illustrated in FIGS. 1 and 2, the connector housing 33 is shaped like a square pillar opened in the first direction X1. The connector housing 33 is configured to be fit onto the counterpart housing 23. Specifically, the connector housing 33 can be fit onto the counterpart housing 23 by moving the connector 31 in the first direction X1 relative to the counterpart connector 21. As illustrated in FIG. 2, on the connector housing 33, a wall portion 33a extending along the second axis Y has a slit 33b that penetrates along the third axis Z and extends along the first axis X. The slit 33b extends in the first opposite direction X2 from one end of the connector housing 33 on the side of the first direction X1. The slit 33b is formed so as to introduce the protruding extension 24 including the extruding portion 26 of the counterpart housing 23. Moreover, the slit 33b allows the engaged portion 25 to move along the first axis X while protruding out of the connector housing 33. The wall portion 33a also has a rotating shaft 33c that projects outward along the third axis Z. The rotating shaft 33c is provided at the center of the connector housing 33 in the width direction along the second axis Y. Moreover, a wall portion 33d extending along the third axis Z on the connector housing 33 has a rail portion 33e that protrudes outward along the second axis Y and extends along the first axis X. As illustrated in FIG. 2, a thick portion 33f having a larger thickness than other portions is formed around the slit 33b on the wall portion 33a. Thus, the wall portion 33a has a step 33g on the edge of the thick portion 33f.
The wall portion 33a also have a mounting portion 41 where the lock member 36 can be mounted. The mounting portion 41 allows the lock member 36 to be mounted by a relative movement to the mounting portion 41 in the second direction Y1 along the second axis Y. The mounting portion 41 is provided to be separated from the slit 33b and the rotating shaft 33c in the first opposite direction X2 on the wall portion 33a. Moreover, the mounting portion 41 is provided to be separated from the slit 33b and the rotating shaft 33c in the second opposite direction Y2, which is opposite to the second direction Y1, on the wall portion 33a.
As illustrated in FIGS. 6 and 7, the mounting portion 41 has a pair of rail grooves 41a that are recessed along the third axis Z and extend along the second axis Y. The rail grooves 41a are opened in the second opposite direction Y2. The mounting portion 41 also has terminal end portions 41b that close the rail grooves 41a in the second direction Y1 at the ends of the rail grooves 41a on the side of the second direction Y1. The rail groove 41a has a horizontal groove 41c that is recessed in a direction crossing the recessing direction of the rail groove 41a. The mounting portion 41 also has a retaining convex portion 41d between the pair of rail grooves 41a. As illustrated in FIG. 10, the retaining convex portion 41d has an inclined face 41e at the corner on the side of the second opposite direction Y2. The mounting portion 41 also has a position-keeping convex portion 41f between the pair of rail grooves 41a. As illustrated in FIG. 6, the position-keeping convex portion 41f is shifted in the first direction X1 relative to the retaining convex portion 41d. The position-keeping convex portion 41f is shifted in the second direction Y1 relative to the retaining convex portion 41d. As illustrated in FIGS. 9 and 11, the position-keeping convex portion 41f has an inclined face 41g at a corner on the side of the second direction Y1. The position-keeping convex portion 41f has an inclined face 41h at a corner on the side of the second opposite direction Y2. As illustrated in FIGS. 6 and 7, the wall portion 33a of the connector housing 33 has a support portion 42. The support portion 42 is provided on the side of the first opposite direction X2 on the mounting portion 41. The support portion 42 is erected along the third axis Z and extends along the second axis Y. As illustrated in FIGS. 12 and 13, the support portion 42 is provided to be contactable with an end face of the lock member 36, which is mounted on the mounting portion 41, on the side of the first opposite direction X2.
Configuration of Lever 34
The lever 34 is configured with a resin material.
As illustrated in FIGS. 1 and 2, the lever 34 is shaped like a square pillar. The inner surface of the lever 34 has a concave portion 34a that extends along the first axis X and can be fit onto the rail portion 33e of the connector housing 33. The lever 34 is fit onto the connector housing 33. The lever 34 can be moved relative to the connector housing 33 along the first axis X by guiding the concave portion 34a to the rail portion 33e. The lever 34 can be moved relative to the connector housing 33 in the range from a first position P1 (see FIGS. 1 and 4) on the side of the first opposite direction X2 to a second position P2 (see FIG. 5) separated from the first position P1 in the first direction X1.
As illustrated in FIGS. 4 and 5, on the lever 34, a wall portion 34b extending along the second axis Y has a coupled portion 34c penetrating along the third axis Z. The coupled portion 34c is provided near one end on the lever 34 in the second direction Y1 along the second direction Y1. The coupled portion 34c extends along the second axis Y and slightly tilts toward the first opposite direction X2 as extending along the second direction Y1.
As illustrated in FIG. 5, the lever 34 has a contact portion 34d. The contact portion 34d is provided on one end of the lever 34 on the side of the first opposite direction X2. In other words, a part of one end face of the lever 34 on the side of the first opposite direction X2 serves as the contact portion 34d.
Configuration of Arm 35
The arm 35 is configured with a resin material.
As illustrated in FIG. 3, the arm 35 has a central hole 35a, a pair of engaging portions 35b extending in one direction with respect to the central hole 35a, and an extended portion 35c that extends to the other direction opposite from the engaging portions 35b with respect to the central hole 35a. The arm 35 is attached to the connector housing 33 such that the rotating shaft 33c passes through the central hole 35a. In other words, the arm 35 is supported so as to pivot about the rotating shaft 33c. The arm 35 is provided such that the pair of engaging portions 35b pivots about the central hole 35a on the side of the second opposite direction Y2 that is opposite to the second direction Y1 and the extended portion 35c pivots about the central hole 35a on the side of the second direction Y1.
The pair of engaging portions 35b has opposing surfaces constituting a slit 35d. As illustrated in FIG. 4, the clearance of the slit 35d is set such that the engaged portion 25 of the counterpart housing 23 can be inserted into the slit 35d. Thus, the pair of engaging portions 35b can be engaged with the engaged portion 25. The slit 35d is curved in a direction that can draw the engaged portion 25 to the proximal side of the engaging portions 35b, that is, the side of the first opposite direction X2 by pivoting the arm 35 to move the distal-end side of the pair of engaging portions 35b in the first opposite direction X2.
The distal-end portion of the extended portion 35c has a coupling shaft 35e that projects along the third axis Z. As illustrated in FIGS. 4 and 5, the coupling shaft 35e is provided to penetrate the coupled portion 34c of the lever 34. The coupling shaft 35e is drivingly coupled to the lever 34 so as to move the arm 35 in a direction different from the moving direction of the lever 34 according to a relative movement of the lever 34 along the first axis X. In other words, the coupling shaft 35e is drivingly coupled to the lever 34 so as to pivot the arm 35 while moving in the coupled portion 34c according to a relative movement of the lever 34 along the first axis X. Thus, the arm 35 is drivingly coupled to the lever 34.
With this configuration, the connector housing 33 is configured to approach a state of fit to the counterpart housing 23 as the lever 34 moves from the first position P1 (see FIG. 4) to the second position P2 (see FIG. 5). Specifically, the connector housing 33 is configured to move relative to the counterpart housing 23 and approach a state of fit to the counterpart housing 23 as the engaging portions 35b in engagement with the engaged portion 25 of the counterpart housing 23 move according to a movement of the lever 34 from the first position P1 to the second position P2. In other words, as the lever 34 moves from the first position P1 to the second position P2, the coupling shaft 35e penetrating the coupled portion 34c of the lever 34 moves from a fifth position P5 (see FIG. 4) to a sixth position P6 (see FIG. 5) and pivots the arm 35. Thus, the engaging portions 35b moving with the arm 35 operate to draw the engaged portion 25, so that the connector housing 33 moves relative to the counterpart housing 23 and approaches a state of fit to the counterpart housing 23.
Configuration of Lock Member 36
The lock member 36 is configured with a resin material.
As illustrated in FIGS. 8, 12, and 13, the lock member 36 includes a pair of sliding portions 36a, a first coupling portion 36b that couples the pair of sliding portions 36a, a second coupling portion 36c, and a third coupling portion 36d. The sliding portions 36a are fit into the rail grooves 41a of the mounting portion 41 and are slidable along the rail grooves 41a. The sliding portion 36a has a convex portion 36e to be fit into the horizontal groove 41c of the rail groove 41a. The sliding portions 36a are fit into the rail grooves 41a and the convex portions 36e are fit into the horizontal grooves 41c by moving the lock member 36 relative to the mounting portion 41 in the second direction Y1, so that the lock member 36 is mounted on the mounting portion 41. The lock member 36 can be moved relative to the connector housing 33 in the range from a third position P3 (see FIGS. 4, 9, and 12) to a fourth position P4 (see FIGS. 5, 10, 11 and 13) along the second axis Y by sliding the sliding portions 36a along the rail grooves 41a.
In a state in which the lock member 36 is mounted on the mounting portion 41, the first coupling portion 36b couples the ends of the pair of sliding portions 36a on the side of the second direction Y1. The second coupling portion 36c couples the ends of the pair of sliding portions 36a on the side of the second opposite direction Y2. The third coupling portion 36d couples the intermediate portions of the sliding portions 36a.
As illustrated in FIGS. 8 and 10, the third coupling portion 36d has a retaining portion 36f. The retaining portion 36f protrudes from the third coupling portion 36d toward the wall portion 33a of the connector housing 33. As illustrated in FIG. 10, in a state in which the lock member 36 is located at the fourth position P4, the retaining portion 36f suppresses the removal of the lock member 36 from the mounting portion 41 by engagement of the retaining portion 36f with the retaining convex portion 41d in the second opposite direction Y2.
The retaining portion 36f has an inclined face 36g at a corner on the side of the second direction Y1. The inclined face 36g of the retaining portion 36f and the inclined face 41e of the retaining convex portion 41d generate component forces that deform the third coupling portion 36d in a direction separating from the wall portion 33a of the connector housing 33 when the lock member 36 is assembled onto the mounting portion 41. With this configuration, the retaining portion 36f is allowed to slide over the retaining convex portion 41d as the third coupling portion 36d is deformed by a movement of the lock member 36 relative to the mounting portion 41 in the second direction Y1. Thus, the lock member 36 is moved relative to the mounting portion 41 in the second direction Y1, so that the lock member 36 can be smoothly mounted on the mounting portion 41.
As illustrated in FIGS. 8, 9, and 11, the third coupling portion 36d has a position-keeping portion 36h. The position-keeping portion 36h protrudes from the third coupling portion 36d toward the wall portion 33a of the connector housing 33. As illustrated in FIG. 9, in a state in which the lock member 36 is located at the third position P3, the position-keeping portion 36h is engaged with the position-keeping convex portion 41f in the second opposite direction Y2, so that a movement of the lock member 36 from the third position P3 to the fourth position P4 is suppressed to hold the lock member 36 at the third position P3. A movement of the lock member 36 at the third position P3 in the second direction Y1 is suppressed by the terminal end portions 41b (see FIG. 6). As illustrated in FIG. 11, in a state in which the lock member 36 is located at the fourth position P4, the position-keeping portion 36h is engaged with the position-keeping convex portion 41f in the second direction Y1, so that a movement of the lock member 36 from the fourth position P4 to the third position P3 is suppressed to hold the lock member 36 at the fourth position P4. A movement of the lock member 36 at the fourth position P4 in the second opposite direction Y2 is suppressed by the retaining convex portion 41d (see FIG. 10).
The position-keeping portion 36h has an inclined face 36j at a corner on the side of the second opposite direction Y2. The inclined face 36j of the position-keeping portion 36h and the inclined face 41g of the position-keeping convex portion 41f generate component forces that deform the third coupling portion 36d in a direction separating from the wall portion 33a of the connector housing 33 when the lock member 36 is moved from the third position P3 to the fourth position P4. The position-keeping portion 36h has an inclined face 36k at a corner on the side of the second direction Y1. The inclined face 36k of the position-keeping portion 36h and the inclined face 41h of the position-keeping convex portion 41f generate component forces that deform the third coupling portion 36d in a direction separating from the wall portion 33a of the connector housing 33 when the lock member 36 is moved from the fourth position P4 to the third position P3. With this configuration, the position-keeping portion 36h is allowed to slide over the position-keeping convex portion 41f as the third coupling portion 36d is deformed by a movement of the lock member 36 relative to the mounting portion 41 along the second axis Y. Thus, the lock member 36 is moved along the second axis Y with a force capable of deforming the third coupling portion 36d, so that the position of the lock member 36 can be switched between the third position P3 and the fourth position P4.
The first coupling portion 36b has an operation portion 36m. The operation portion 36m is shaped like, for example, steps that allow an operator to easily operate the lock member 36 with the fingers.
The second coupling portion 36c has a lock portion 36n. As illustrated in FIGS. 5 and 13, the lock portion 36n regulates a movement of the lever 34 to the first position P1 by making contact with the contact portion 34d of the lever 34 at the second position P2 in a state in which the lock member 36 is located at the fourth position P4. Furthermore, in a state in which the lock member 36 is located at the fourth position P4, the lock portion 36n is held by the contact portion 34d of the lever 34 located at the second position P2 and the support portion 42 of the connector housing 33 along the first axis X. The lock portion 36n of the present embodiment has an inclined portion 36p that gradually decreases in height toward the support portion 42, that is, toward the first opposite direction X2 according to a height of the support portion 42 from the wall portion 33a.
As illustrated in FIGS. 4 and 12, in a state in which the lock member 36 is located at the third position P3 and the lever 34 is located at the first position P1, the lock member 36 is covered with the lever 34. Specifically, as illustrated in FIG. 12, the lever 34 has a storage portion 34e that accommodates the lock member 36 between the wall portion 33a and the storage portion 34e in a state in which the lock member 36 is located at the third position P3 and the lever 34 is located at the first position P1.
In a state in which the lever 34 is located at the first position P1, the lock member 36 is brought into contact with the lever 34, so that a movement of the lock member 36 from the third position P3 to the fourth position P4 is regulated. Specifically, as illustrated in FIG. 12, the lever 34 has a regulating surface 34f that regulates a movement of the lock member 36 to the fourth position P4 in a state in which the lock member 36 is located at the third position P3 and the lever 34 is located at the first position P1. The regulating surface 34f is configured with the inner wall surface of the storage portion 34e.
As illustrated in FIGS. 5 and 13, the lock member 36 is exposed from the lever 34 in a state in which the lever 34 is located at the second position P2. Specifically, in a state in which the lever 34 is located at the second position P2, the lock member 36 is exposed from the lever 34 to allow an operator to operate the lock member 36 with the fingers and cannot come into contact with the regulating surface 34f, so that the lock member 36 can be moved from the third position P3 to the fourth position P4.
Configuration for Keeping Initial Position of Arm 35
As illustrated in FIGS. 15 and 16, the arm 35 has a locking protrusion 51. As illustrated in FIG. 15, in a state in which the lever 34 is located at the first position P1, the locking protrusion 51 is fit into the slit 33b, so that a movement of the arm 35 can be regulated at the initial position.
As illustrated in FIGS. 4, 14, and 15, the lever 34 has an elastic piece 52. As illustrated in FIG. 15, the elastic piece 52 presses the arm 35 in a direction that fits the locking protrusion 51 into the slit 33b.
Thereafter, the locking protrusion 51 is pressed out of the slit 33b by the extruding portion 26 of the counterpart housing 23 in an initial state of fit into the connector housing 33. As illustrated in FIG. 4, the initial fit state is a state in which the connector housing 33 and the counterpart housing 23 are slightly fit to each other, that is, a state in which the engaged portion 25 is placed between the distal-end portions of the pair of engaging portions 35b into engagement with the engaging portions 35b.
Specifically, as illustrated in FIG. 15, the locking protrusion 51 has a locking face 51a that can come into contact with an inner wall surface 33h of the slit 33b. When the lever 34 starts moving from the first position P1 to the second position P2 with the locking protrusion 51 fit into the slit 33b, the locking face 51a comes into contact with the inner wall surface 33h of the slit 33b to prevent component forces from being generated in a direction against the pressing force of the elastic piece 52. In other words, the inner wall surface 33h and the locking face 51a are parallel flat surfaces along the third axis Z. When the lever 34 starts moving from the first position P1 to the second position P2 to pivot the arm 35 with the locking protrusion 51 fit into the slit 33b, the locking face 51a comes into surface contact with the inner wall surface 33h in a direction orthogonal to the third axis Z to regulate the movement of the arm 35.
The locking protrusion 51 has a first inclined face 51b. The first inclined face 51b is inclined with respect to a plane along the third axis Z. The first inclined face 51b generates component forces that allow the lever 34 to slide over the step 33g on a surface facing the arm 35 on the connector housing 33 when the lever 34 moves from the second position P2 side to the first position P1 side.
As illustrated in FIGS. 16 to 18, the locking protrusion 51 has a second inclined face 51c. The second inclined face 51c is inclined with respect to a plane along the third axis Z. The second inclined face 51c comes into contact with the extruding portion 26 so as to generate component forces in the direction of extrusion from the slit 33b when the connector housing 33 and the counterpart housing 23 approach the initial fit state. FIG. 17 illustrates a state in which the connector housing 33 and the counterpart housing 23 are not fit to each other. FIG. 18 illustrates an initial state of fit between the connector housing 33 and the counterpart housing 23. The extruding portion 26 of the present embodiment has an inclined face 26a that comes into contact with the locking protrusion 51 so as to generate component forces in a direction that presses the locking protrusion 51 out of the slit 33b when approaching the initial fit state.
As illustrated in FIGS. 4 and 5, the elastic piece 52 is provided on a part of the wall portion 34b of the lever 34. The wall portion 34b has a U-shaped slit 34g, and a portion determined by the slit 34g constitutes the elastic piece 52.
As illustrated in FIG. 14, the elastic piece 52 has a pressing portion 52a at the distal-end portion. The pressing portion 52a protrudes to the arm 35. The elastic piece 52 presses the arm 35 with the pressing portion 52a in a state in which the lever 34 is located at the first position P1. The elastic piece 52 does not press the arm 35 in a state in which the lever 34 is not located at the first position P1. For example, as illustrated in FIG. 5, in a state in which the lever 34 is located at the second position P2, the elastic piece 52 is displaced from the arm 35 and does not press the arm 35.
As illustrated in FIG. 15, the pressing portion 52a has a third inclined face 52b. The third inclined face 52b generates component forces that allow the pressing portion 52a to slide over the arm 35 when the lever 34 moves from the second position P2 side to the first position P1 side.
Operations performed when the connector assembly 11 configured thus is connected will be describe below.
As illustrated in FIG. 1, before the connector 31 is connected to the counterpart connector 21, the lever 34 is located at the first position P1. In a state in which the lever 34 is located at the first position P1, as illustrated in FIG. 15, the arm 35 is pressed in a direction along which the locking protrusion 51 is fit into the slit 33b by the elastic piece 52. The rotation of the arm 35 is suppressed by the locking protrusion 51 fit into the slit 33b, so that the arm 35 is kept at the initial position. Thus, the movement of the lever 34 to the second position P2 is also suppressed while the lever 34 is drivingly coupled to the arm 35. As illustrated in FIGS. 4 and 12, in a state in which the lever 34 is located at the first position P1, the lock member 36 at the third position P3 is covered with the lever 34. In a state in which the lever 34 is located at the first position P1, as illustrated in FIG. 12, a movement of the lock member 36 from the third position P3 to the fourth position P4 is regulated by bringing the lock member 36 into contact with the regulating surface 34f of the lever 34.
Furthermore, when the connector 31 is connected to the counterpart connector 21, an operator moves the connector 31 relative to the counterpart connector 21 in the first direction X1 and places the connector housing 33 into an initial fit state in which the connector housing 33 is slightly fit onto the counterpart housing 23. Thus, as illustrated in FIG. 18, the extruding portion 26 of the counterpart housing 23 is introduced into the slit 33b. Thereafter, the locking protrusion 51 of the arm 35 is pressed out of the slit 33b by the extruding portion 26 against the pressing force of the elastic piece 52. Thus, a movement of the arm 35 from the initial position, that is, a rotation is permitted, and a movement of the lever 34 to the second position P2 is also permitted while the lever 34 is drivingly coupled to the arm 35. The engaged portion 25 of the counterpart housing 23 is inserted into the slit 35d between the pair of engaging portions 35b and is placed in engagement with the engaging portions 35b.
The operator then holds the lever 34 to move the lever 34 in the first direction X1. Thus, the lever 34 moves from the first position P1 to the second position P2. At this point, the arm 35 pivots to move the engaging portions 35b in engagement with the engaged portion 25 as the lever 34 moves. The engaging portions 35b at this point operate to draw the engaged portion 25 inward, allowing the connector housing 33 to move relative to the counterpart housing 23 into a fit state in which the connector housing 33 is completely fit onto the counterpart housing 23. Thus, the terminals 32 are electrically connected to the counterpart terminals 22. In a state in which the lever 34 is located at the second position P2, the lock member 36 is exposed from the lever 34. Specifically, in a state in which the lever 34 is located at the second position P2, the lock member 36 is operably exposed from the lever 34 and cannot come into contact with the regulating surface 34f, so that a movement of the lock member 36 from the third position P3 to the fourth position P4 is permitted.
The operator then operates the operation portion 36m of the lock member 36 to move the lock member 36 from the third position P3 to the fourth position P4. Thus, as illustrated in FIGS. 5 and 13, the lock portion 36n of the lock member 36 can come into contact with the contact portion 34d of the lever 34 located at the second position P2, so that a movement of the lever 34 to the first position P1 is regulated. This suppresses disengagement of the connector housing 33 from the counterpart housing 23, the disengagement being caused by, for example, external forces such as vibrations.
The effects of the embodiment will be described below.
- (1) In a state in which the locking protrusion 51 is not pressed out of the slit 33b by the extruding portion 26 of the counterpart housing 23 in an initial state of fit into the connector housing 33, the arm 35 is pressed in a direction along which the locking protrusion 51 is fit into the slit 33b by the elastic piece 52. Thus, a movement of the arm 35 is regulated by fitting the locking protrusion 51 into the slit 33b. Accordingly, a movement of the lever 34 drivingly coupled to the arm 35 is also regulated. Hence, for example, movements of the arm 35 and the lever 34 from the initial position are suppressed before the connector housing 33 is fit onto the counterpart housing 23. This can avoid problems caused by movements of the arm 35 and the lever 34 from the initial position, thereby normally fitting the connector housing 33 onto the counterpart housing 23 with stability. Moreover, for example, wrong assembly of the connector housing 33 to a counterpart housing other than the counterpart housing 23 having the extruding portion 26 is suppressed. Thereafter, when the locking protrusion 51 is pressed out of the slit 33b by the extruding portion 26 of the counterpart housing 23 in an initial fit state, the arm 35 is allowed to move. When the lever 34 is moved from the first position P1 to the second position P2 along the first axis X, the connector housing 33 is fit onto the counterpart housing 23.
- (2) The arm 35 has the engaging portions 35b that can be engaged with the engaged portion 25 of the counterpart housing 23. The arm 35 then moves as the lever 34 moves from the first position P1 to the second position P2, and the engaging portions 35b in engagement with the engaged portion 25 of the counterpart housing 23 also move, so that the connector housing 33 can be brought close to a state of fit to the counterpart housing 23.
- (3) In the initial fit state of the connector housing 33 and the counterpart housing 23, the arm 35 is allowed to move and the engaging portions 35b are engaged with the engaged portion 25. Thus, the connector housing 33 and the counterpart housing 23 can be normally fit to each other by operating the lever 34. Specifically, in a configuration in which the engaging portions 35b are likely to be disengaged from the engaged portion 25 while the arm 35 is allowed to move in an initial fit state, the lever 34 may be erroneously operated in the disengaged state. The present embodiment can avoid such a problem. Thus, the connector housing 33 and the counterpart housing 23 can be normally fit to each other with higher stability.
- (4) The slit 33b has the function of receiving the locking protrusion 51 capable of regulating a movement of the arm 35 and introducing the extruding portion 26 that presses the locking protrusion 51 and the function of moving the engaged portion 25 along the first axis X while protruding the engaged portion 25 toward the engaging portions 35b. Thus, for example, as compared with a configuration in which the connector housing is provided with two slits having two different functions, the configuration of the connector housing 33 is simplified.
- (5) Even when the lever 34 starts moving from the first position P1 to the second position P2 with the locking protrusion 51 fit into the slit 33b, the locking face 51a of the locking protrusion 51 comes into contact with the inner wall surface 33h of the slit 33b to prevent component forces from being generated in a direction against the pressing force of the elastic piece 52. Thus, a movement of the arm 35 from the initial position can be firmly suppressed.
- (6) When the lever 34 moves from second position P2 side to the first position P1 side, the first inclined face 51b of the locking protrusion 51 generates component forces that allow the lever 34 to slide over the step 33g. Thus, the locking protrusion 51 can smoothly slide over the step 33g, thereby reaching the slit 33b without any interruption.
- (7) When the connector housing 33 approaches an initial state of fit to the counterpart housing 23, component forces are generated in the direction of extrusion from the slit 33b by the second inclined face 51c of the locking protrusion 51 that comes into contact with the extruding portion 26. Thus, the locking protrusion 51 is smoothly pressed out of the slit 33b.
- (8) The elastic piece 52 does not press the arm 35 in a state in which the lever 34 is not located at the first position P1, thereby suppressing, for example, an excessive press on the arm 35 into contact with the connector housing 33 when the arm 35 moves. Thus, for example, a sliding resistance against a movement of the arm 35 can be suppressed. Moreover, for example, wear of the arm 35 and the connector housing 33 can be suppressed.
- (9) When the lever 34 moves from second position P2 side to the first position P1, the third inclined face 52b of the elastic piece 52 generates component forces for sliding the lever 34 onto the arm 35. Thus, the elastic piece 52 can smoothly slide onto the arm 35 so as to press the arm 35 without any interruption.
The present embodiment can be implemented with the modifications below. The present embodiment and the following modification examples can be implemented in combination unless technical contradictions arise.
- In the foregoing embodiment, the arm 35 has the engaging portions 35b that can be engaged with the engaged portion 25 of the counterpart housing 23. The configuration is not limited thereto, and the engaging portions 35b may be omitted. In other words, the connector housing 33 may be modified to another configuration if the configuration approaches a state of fit to the counterpart housing 23 as the lever 34 moves from the first position P1 to the second position P2. For example, the arm 35 may be configured to be drivingly coupled to still another member that is engaged with the counterpart housing 23 to operate in the same manner as in the foregoing embodiment.
- In the foregoing embodiment, the lock member 36 can move in the range of the third position P3 and the fourth position P4 along the second axis Y crossing the first axis X. The configuration is not limited thereto. For example, the lock member 36 may be configured to move along the first axis X.
- In the foregoing embodiment, in a state in which the lever 34 is located at the first position P1, a movement of the lock member 36 from the third position P3 to the fourth position P4 is regulated by bringing the lock member 36 into contact with the lever 34. The configuration is not limited thereto, and the regulation may be omitted.
- In the foregoing embodiment, a movement of the lever 34 is regulated by bringing the lock member 36 into contact with the contact portion 34d at the end of the lever 34 on the side of the first opposite direction X2. The configuration is not limited thereto, and the lock member 36 may come into contact with a contact portion provided at another portion of the lever.
- In the foregoing embodiment, the connector housing 33 has the support portion 42 capable of holding the lock member 36 with the lever 34 along the first axis X. The configuration is not limited thereto, and the support portion 42 may be omitted. The lock portion 36n of the lock member 36 has the inclined portion 36p that is inclined according to a height of the support portion 42 from the wall portion 33a. The configuration is not limited thereto, and the inclined portion 36p may be omitted.
- In the foregoing embodiment, the mounting portion 41 of the connector housing 33 may be modified to another configuration along with the configuration of the lock member 36 if the lock member 36 can be movably held.
For example, the mounting portion 41 may guide the lock member by using another configuration without the pair of rail grooves 41a.
For example, the mounting portion 41 may suppress derailment of the lock member 36 from the rail grooves 41a by using another configuration without the horizontal grooves 41c provided for the rail grooves 41a.
Moreover, for example, the mounting portion 41 may be configured such that the lock member 36 is mounted by a relative movement in a direction other than the second direction Y1.
For example, the mounting portion 41 may suppress removal of the lock member 36 from the mounting portion 41 by using another configuration without the retaining convex portion 41d.
Moreover, for example, the mounting portion 41 may hold the lock member 36 at the third position P3 or the fourth position P4 by using another configuration without the position-keeping convex portion 41f.
- In the foregoing embodiment, the retaining portion 36f and the position-keeping portion 36h are provided on the same third coupling portion 36d. The configuration is not limited thereto, and the retaining portion 36f and the position-keeping portion 36h may be provided on different coupling portions. For example, the lock member 36 may be configured with an additional fourth coupling portion that couples the pair of sliding portions 36a, the retaining portion 36f may be provided on the third coupling portion 36d, and the position-keeping portion 36h may be provided on the fourth coupling portion.
- In the foregoing embodiment, in the initial fit state of the connector housing 33 and the counterpart housing 23, the arm 35 is allowed to move and the engaging portions 35b are engaged with the engaged portion 25. The configuration is not limited thereto. The engaging portions 35b may be placed without being engaged with the engaged portion 25. For example, in the initial fit state, the arm 35 may be allowed to move without engagement of the engaging portions 35b and the engaged portion 25, and the engaging portions 35b may be engaged with the engaged portion 25 by a further relative movement of the connector housing 33 and the counterpart housing 23. In other words, when the connector housing 33 is being fit onto the counterpart housing 23, the arm 35 may be allowed to move and the engaging portions 35b may be engaged with the engaged portion 25 at different times.
- In the foregoing embodiment, the slit 33b has the function of receiving the locking protrusion 51 and introducing the extruding portion 26 and the function of moving the engaged portion 25, which protrudes toward the engaging portions 35b, along the first axis X. The slit 33b does not necessarily have the two functions. For example, the connector housing may be provided with two slits having two different functions.
- In the foregoing embodiment, the locking protrusion 51 has the first inclined face 51b that generates component forces for sliding over the step 33g. The configuration is not limited thereto, and the first inclined face 51b may be omitted. For example, if the connector housing 33 does not have the step 33g on a surface facing the arm 35, the locking protrusion 51 may be configured without the first inclined face 51b.
- In the foregoing embodiment, the locking protrusion 51 has the second inclined face 51c that comes into contact with the extruding portion 26 so as to generate component forces in the direction of extrusion from the slit 33b. The configuration is not limited thereto, and the second inclined face 51c may be omitted. For example, if the extruding portion 26 has the inclined face 26a as in the present embodiment, the locking protrusion 51 may be configured without the second inclined face 51c.
- In the foregoing embodiment, in a state in which the lever 34 is not located at the first position P1, the elastic piece 52 does not press the arm 35. The configuration is not limited thereto, and the arm 35 may be pressed also in a state in which the lever 34 is not located at the first position P1.
- In the foregoing embodiment, the elastic piece 52 has the third inclined face 52b that generates component forces for sliding the lever 34 onto the arm 35 when the lever 34 moves from the second position P2 side to the first position P1. The configuration is not limited thereto, and the third inclined face 52b may be omitted. For example, if the arm 35 has an inclined face that generates component forces for sliding the elastic piece 52 onto the arm 35, the elastic piece 52 may be configured without the third inclined face 52b.
- In the foregoing embodiment, the plurality of arms 35 may be provided for the single connector 31, which has not been particularly mentioned. For example, the arms 35 may be provided on the front and back sides of the connector 31 along the third axis Z or laterally provided along the second axis Y. As a matter of course, the portion provided with the arm 35 needs to have configurations for the arm 35, for example, the slit 33b and the rotating shaft 33c. Moreover, the counterpart housing 23 surely needs to be provided with the engaged portions 25 corresponding to the arms 35.
- In the foregoing embodiment, the plurality of lock members 36 may be provided for the single connector 31, which has not been particularly mentioned. For example, the lock members 36 may be provided on the front and back sides of the connector 31 along the third axis Z or laterally provided along the second axis Y. As a matter of course, the portion provided with the lock member 36 needs to have configurations for the lock member 36, for example, the mounting portion 41.
- In the foregoing embodiment, the counterpart connector 21 includes the two counterpart terminals 22 and the connector 31 includes the two terminals 32. The number of counterpart terminals 22 and the number of terminals 32 may be changed to other numbers, e.g., one or three or more.
The lever 34 of the present embodiment may be referred to as a slide cover or a linear slider that is mounted on the connector housing 33 so as to linearly reciprocate along the first axis X and covers a part of the outermost surface of the connector housing 33. The arm 35 may be referred to as an interlocking lever that is rotatably pivoted on the connector housing 33, is slidably engaged with the lever 34, and pivots in synchronization with a movement of the lever 34.
The first axis X of the embodiment may be referred to as a linear attaching/detaching direction of the connector 31 and the counterpart connector 21. The second axis Y of the embodiment may be referred to as the width direction of the connector 31 orthogonal to the first axis X. The third axis Z may be referred to as the thickness direction of the connector 31 orthogonal to the first axis X and the second axis Y.
As illustrated in FIGS. 15 to 18, in a state in which the locking protrusion 51 is fit into the slit 33b, the locking face 51a extending along the third axis Z on the locking protrusion 51 may be oriented in the second opposite direction Y2 and may face the inner wall surface 33h of the slit 33b, the inner wall surface 33h extending along the third axis Z.
As illustrated in FIGS. 14, 17, and 18, the elastic piece 52 may have one end as a fixed end in the first opposite direction X2 and the other end as a free end in the first direction X1. The pressing portion 52a may be provided on the free end of the elastic piece 52. The pressing portion 52a may press the arm 35 in a direction along the third axis Z.
With this configuration, when the lever 34 is being moved from the first position P1 to the second position P2 before the connector housing 33 is fit onto the counterpart housing 23, the locking protrusion 51 slides over the inner wall surface 33h to deform the free end of the elastic piece 52 in a direction along the third axis Z, which suppresses a pivot of the arm 35 in the second opposite direction Y2.
The second inclined face 51c of the locking protrusion 51 may be inclined with respect to a plane along the third axis Z and may be oriented in the first direction X1.
With this configuration, the locking protrusion 51 is pressed out of the slit 33b in a direction along the third axis Z by the extruding portion 26 of the counterpart housing 23 in an initial state of fit to the connector housing 33.
As illustrated in FIG. 15, the first inclined face 51b of the locking protrusion 51 may be inclined with respect to a plane along the third axis Z and may be oriented in the second direction Y1. Moreover, the third inclined face 52b of the pressing portion 52a of the elastic piece 52 may be inclined with respect to a plane along the third axis Z and may be oriented in the second opposite direction Y2.
With this configuration, when the arm 35 pivots in the second direction Y1 as the lever 34 moves from the second position P2 side to the first position P1 side, the locking protrusion 51 can slide over the step 33g located ahead of the slit 33b in the second opposite direction Y2 and can be fit into the slit 33b by the first inclined face 51b. The elastic piece 52 can be deformed in the direction of the third axis Z and slid onto the arm 35 by the third inclined face 52b coming into contact with the pivoting arm 35.
