The foregoing summary is illustrative only and is not intended to be in any way limiting. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features will become apparent by reference to the drawings and the following detailed description.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
[Description of Embodiments of Present Disclosure]
First, embodiments of the present disclosure are listed and described.
(1) The connector of the present disclosure is provided with a connector body including a guide portion, and a lever including a guide receiving portion for contacting the guide portion, the lever being operated to connect the connector to a mating connector, wherein the lever is rotatable about a rotary shaft with respect to the connector body to a guide start position where guide by the guide portion is started and a guide end position where the guide by the guide portion is ended, at least one of the guide portion and the guide receiving portion arcuately extends with the rotary shaft as a center, and the guide receiving portion contacts the guide portion with a larger contact pressure when the lever is at the guide end position than when the lever is at the guide start position.
In this connector, the guide receiving portion can be brought into contact with the guide portion with a larger contact pressure when the lever is at the guide end position than when the lever is at the guide start position. Thus, the rattling of the lever arranged at the guide end position and the connector body can be suppressed.
(2) Preferably, one of the guide portion and the guide receiving portion has a first guide surface in contact with or facing the other at the guide start position, a second guide surface arranged at a position more away from the rotary shaft than the first guide surface and in contact with the other at the guide end position, and a third guide surface obliquely connected to the first and second guide surfaces.
Since this connector has the third guide surface obliquely connected to the first and second guide surfaces, the lever can be smoothly moved from the guide start position to the guide end position.
(3) Preferably, the one of the guide portion and the guide receiving portion includes a projection on the second guide surface, the other includes a recess to be fit to the projection at the guide end position, and the recess is in contact with the projection on both sides in a rotating direction of the lever when viewed from a direction parallel to an axis of the rotary shaft.
In this connector, the recess is in contact with the projection on both sides in the rotating direction when viewed from the direction parallel to the axis of the rotary shaft. Thus, a state where the projection is fit in the recess without rattling can be maintained. As a result, the rattling of the lever and the connector body can be more effectively suppressed.
(4) Preferably, the connector body includes a locking portion, the lever includes a lock receiving portion lockable to the locking portion, and the locking portion and the lock receiving portion do not contact each other and are arranged to face each other in a rotating direction of the lever when the lever is at the guide end position.
In this connector, the locking portion and the lock receiving portion do not contact each other and are arranged to face each other in the rotating direction of the lever when the lever is at the guide end position. Thus, if external vibration is applied to the connector, the transmission of the vibration between the locking portion and the lock receiving portion can be suppressed.
[Details of Embodiment of Present Disclosure]
A specific example of the present disclosure is described below with reference to the drawings. Note that the present invention is not limited to these illustrations and is intended to be represented by claims and include all changes in the scope of claims and in the meaning and scope of equivalents.
A connector 10 is illustrated in one embodiment. The connector 10 is a lever-type connector. As shown in
Note that, in the following description, a side of the connector 10 to be connected to the mating connector 90 is referred to as a front side and an opposite side thereof is referred to as a back side concerning a front-back direction.

The lever 50 is made of synthetic resin. The lever 50 is a member to be pinched and operated by a worker when the connector 10 is connected to the mating connector 90. Specifically, the lever 50 includes a pair of upper and lower arm portions 51, a first coupling portion 52 coupling base end sides (sides of the rotary shafts 54 to be described later) of the pair of arm portions 51 and a second coupling portion 53 coupling tip sides (sides to be pinched by the worker) of the pair of arm portions 51. Each of the arm portions 51, the first coupling portion 52 and the second coupling portion 53 is plate-like.
The lever 50 includes a pair of upper and lower rotary shafts 54 and a pair of upper and lower drive shafts 55 as shown in

An assembling procedure of the connector 10 is described next.
First, the pair of sliders 80 are mounted into the housing 21. Then, the lever 50 is mounted on the housing 21 from behind. Thereafter, the unillustrated terminal fittings are inserted into the housing 21 and the wire cover 22 is assembled with the housing 21. In the above way, the assembling of the connector 10 is completed.
Functions and effects of the connector 10 are described.
In connecting the connector 10 to the mating connector 90, the lever 50 is arranged at the initial position as shown in
The lever 50 rotating in the connecting direction passes through the guide start position and reaches the guide end position. The guide start position is a position where tip parts in the rotating direction (end parts in the connecting direction) of the outer side surfaces 60C and the first guide surfaces 31 are radially spaced apart and facing each other. At the guide start position, the outer side surfaces 60C of the guide receiving portions 60 of the lever 50 are facing the first guide surfaces 31 of the guide portions 30 while being radially spaced apart from the first guide surfaces 31 as shown in
In the process of rotating the lever 50 to the guide end position, the outer side surfaces 60C of the guide receiving portions 60 are in contact with the guide surfaces 30A of the guide portions 30 while the tips in the rotating direction (end parts in the connecting direction) of the guide receiving portions 60 move from the third guide surfaces 33 to the second guide surfaces 32. A contact pressure received from the guide surfaces 30A by the outer side surfaces 60C of the guide receiving portions 60 gradually increases as the lever 50 is rotated by the inclination of the third guide surfaces 33. The lever 50 can smoothly move from the guide start position to the guide end position.
When the outer side surfaces 60C of the guide receiving portions 60 contact the guide surfaces 30A of the guide portions 30, a force is applied to the lever 50 in a direction away from the rotary shafts 54 (radially outward). The rotary shafts 54 contact the rotary shaft receiving portions 24 while pressing the rotary shaft receiving portions 24 in the direction of this force.
When the lever 50 reaches the guide end position, the contact pressure received from the second guide surfaces 32 of the guide portions 30 by the outer side surfaces 60C of the guide receiving portions 60 as shown in
The second guide surface 32 is arranged at a position more away from the rotary shaft 54 than the first guide surface 31. Thus, the guide receiving portions 60 of the lever 50 contact the guide portions 30 with a larger contact pressure when the lever 50 is at the guide end position than when the lever 50 is at the guide start position. Therefore, this connector 10 can suppress the rattling of the lever 50 arranged at the guide end position and the connector body 20.
When the lever 50 reaches the guide end position, the recesses 61 of the lever 50 are resiliently fit to the projections 34 on the second guide surfaces 32. When the projections 34 are fit into the recesses 61, the worker is given a click feeling and can stop the rotating operation of the lever 50. A position where the recesses 61 of the lever 50 are fit to the projections 34 on the second guide surfaces 32 is the guide end position. Further, in the state fit to the projection 34, the recess 61 is in contact with the projection 34 on both sides in the rotating direction when viewed from the vertical direction as shown in
In the process of rotating the lever 50 from the guide start position to the guide end position, the first locking portions 35 of the lever 50 deflect the first lock receiving portions 62 of the connector body 20 and are, thereafter, arranged behind the resiliently returned first lock receiving portions 62 in the connecting direction. When the lever 50 is at the guide end position, the first locking portions 35 (more specifically, the first locking surfaces 35A) and the first lock receiving portions 62 (more specifically, first lock receiving surfaces 62A) do not contact each other and are arranged to face each other in the rotating direction of the lever 50 as shown in
Further, when the lever 50 is at the guide end position, the second locking portions 36 of the lever 50 are arranged behind the second lock receiving portions 63 of the connector body 20 in the releasing direction and the second locking portions 36 (more specifically, the second locking surfaces 36A) and the second lock receiving portions 63 (more specifically, second lock receiving surfaces 63A) do not contact each other and are arranged to face each other in the rotating direction of the lever 50 as shown in
Accordingly, if external vibration is applied to the connector 10, the transmission of the vibration between the first locking portions 35 and the first lock receiving portions 62 can be suppressed and the transmission of the vibration between the second locking portions 36 and the second lock receiving portions 63 can be suppressed. Further, even if the lever 50 moves in the rotating direction from the guide end position when the external vibration is applied to the connector 10, a displacement in the releasing direction can be restricted by the first locking portions 35 and a displacement in the connecting direction can be restricted by the second locking portions 36.
The embodiment disclosed this time should be considered illustrative in all aspects, rather than restrictive.
(1) Although the guide surface (specifically, the first, second and third guide surfaces) of the guide portion is bent at intermediate positions to bring the guide surface more away from the rotary shaft as a configuration for “causing the guide receiving portion to contact the guide portion with a larger contact pressure when the lever is at the guide end position than when the lever is at the guide start position” in the above embodiment, another configuration may be adopted. For example, the entire guide surface of the guide portion may be configured to gradually separate from the rotary shaft along the connecting direction. Alternatively, the guide receiving portion may have a guide surface. Alternatively, a shortest distance between the outer peripheral surface of the rotary shaft and the guide surface may be made shorter when the lever is at the guide end position than when the lever is at the guide start position by causing the rotary shaft to project in the radial direction.
(2) Although both the guide portion and the guide receiving portion arcuately extend in the above embodiment, at least one of these may arcuately extend. For example, the guide receiving portion may be a protrusion for contacting the arcuately extending guide portion.
(3) The projection only has to be configured to fit into the recess and is not limited to the configuration in which the projection is in contact with the recess at two positions in the rotating direction when viewed from a direction parallel to the axis of the rotary shaft.
(4) Although the outer side surface of the guide receiving portion is arranged away from the first guide surface at the guide start position in the above embodiment, the outer side surface of the guide receiving portion may contact the first guide surface of the guide portion with a smaller contact pressure at the guide start position than at the guide end position.
(5) Although the sliders including the cam grooves are provided separately from the lever in the above embodiment, the lever may include cam grooves. If the lever includes the cam grooves, the sliders can be omitted.
From the foregoing, it will be appreciated that various exemplary embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various exemplary embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
