Description

TECHNICAL FIELD

The present disclosure relates to a lever-type connector.

BACKGROUND

Lever-type connectors are conventionally known with which fitting to a counterpart connector is enabled by operating a lever. For example, lever-type connectors described in Patent Documents 1 to 3 each have a lever on a wire cover that covers a wire draw-out surface of a housing. The housings of these lever-type connectors each have sliders that slide in response to an operation of the lever. Each slider has a cam groove capable of receiving a cam follower provided in a counterpart connector. The slider is held at a predetermined position relative to the housing when fitting to the counterpart connector is initiated. The predetermined position refers to a position at which the cam follower of the counterpart connector is fitted to the cam groove. The slider is slid from the predetermined position by fitting the cam follower to the cam groove and operating the lever. The lever-type connector is normally fitted to the counterpart connector through engagement between the cam groove in the slider and the cam follower of the counterpart connector.

These lever-type connectors described in the cited references 1 and 2 have rack teeth on the sliders and gears on the lever. The sliders of these lever-type connectors move due to meshing between the gears and rack teeth.

SUMMARY OF THE INVENTION

Problems to be Solved

When the wire cover is attached to the housing, there are cases where the gears of the wire cover come into contact with the rack teeth of the sliders and shift the sliders from the predetermined positions. If the sliders are shifted from the predetermined positions, the cam followers of the counterpart connector cannot be fitted to the cam grooves. For this reason, there is a desire to prevent the gears of the wire cover from coming into contact with the rack teeth of the slider and shifting the slider positions when the wire cover is attached to the housing.

The present disclosure aims to provide a lever-type connector capable of preventing a gear of a wire cover from coming into contact with rack teeth of a slider and shifting the slider position when the wire cover is attached to a housing.

Means to Solve the Problem

A lever-type connector of the present disclosure includes: a housing; a slider having a plurality of rack teeth arranged in a first direction, the slider being movable in the first direction relative to the housing; a wire cover installed on the housing and covering a wire draw-out surface of the housing; and a lever configured to move the slider, the lever being rotatably installed on the wire cover and having a gear meshing with the rack teeth, wherein the housing has a fulcrum portion rotatably supporting the wire cover, and a positioning portion coming into contact with the wire cover and causing the gear to be located at a position at which the gear meshes with the rack teeth.

Effect of the Invention

According to the present disclosure, a lever-type connector can be provided that is capable of preventing a gear of a wire cover from coming into contact with rack teeth of the slider and shifting the slider position when the wire cover is attached to a housing.

DETAILED DESCRIPTION TO EXECUTE THE INVENTION

Description of Embodiments of Present Disclosure

Firstly, modes for carrying out the present disclosure will be listed and described.

(1) A lever-type connector of the present disclosure includes: a housing; a slider having a plurality of rack teeth arranged in a first direction, the slider being movable in the first direction relative to the housing; a wire cover installed on the housing and covering a wire draw-out surface of the housing; and a lever configured to move the slider, the lever being rotatably installed on the wire cover and having a gear meshing with the rack teeth, wherein the housing has a fulcrum portion rotatably supporting the wire cover, and a positioning portion coming into contact with the wire cover and causing the gear to be located at a position at which the gear meshes with the rack teeth. This configuration enables the wire cover to be positioned so that the gear meshes with the rack teeth when the wire cover is rotated while being supported by the fulcrum portion. Accordingly, the gear of the wire cover can be prevented from coming into contact with the rack teeth of the slider and shifting the slider position when the wire cover is attached to the housing.

(2) It is preferable that the fulcrum portion has a protruding portion protruding from the housing in a direction intersecting the first direction, the wire cover has a fitting portion fitted to the protruding portion from a direction parallel to the first direction, and the positioning portion is located at an opposite position to the protruding portion relative to the fitting portion and has a face curved in a direction in which the wire cover rotates. This is because this configuration enables the wire cover to be easily positioned.

(3) The housing may have a gear arrangement portion in its center area in the first direction, the gear being arranged in the gear arrangement portion when the wire cover is in a state of being attached to the housing, and both the protruding portion and the positioning portion may be located on one side in the first direction relative to the gear arrangement portion. This is because this configuration enables the housing to be made more compactly than in the case where the protruding portion is provided on one side in the first direction of the housing and the positioning portion is provided on the other side.

(4) It is favorable that the fulcrum portion has a rotation axis portion serving as a rotation center of the wire cover, and a corner portion of a surface of the rotation axis portion that comes into contact with the wire cover has a curved face. This is because this configuration enables the wire cover to rotate more smoothly than in the case where the corner portion of the surface of the rotation axis portion that comes into contact with the wire cover is right-angled.

As shown in FIG. 4, the wire cover 30 has the support portions 35. The support portions 35 are fitted to the support receiving portions 16 of the housing 10. Two support portions 35 are provided, one on the left side and the other on the right side of the wire cover 30. The support portions 35 are provided at rear end portions of the lower faces of the side face portions 30A of the wire cover 30. The support portions 35 are located in a center area in the front-back direction between the front end of the wire cover 30 and the wire guide opening 34. The size of each support portion 35 in the left-right direction is smaller than the size of each side face portion 30A in the left-right direction.

As shown in FIG. 6, the lower face of each support portion 35 includes an inclined face 36, a horizontal face 37, and a curved face 38. The inclined face 36 is provided at a rear end portion of each support portion 35. The inclined face 36 is inclined upward toward the rear when the wire cover 30 is in a state of being attached to the housing 10. The inclined face 36 constitutes the lower face of a later-described fitting portion 52. The horizontal face 37 is provided in a center area of each support portion 35 in the front-back direction. The horizontal face 37 is in surface contact with the bottom face 16A of the corresponding support receiving portion 16 when the wire cover 30 is in a state of being attached to the housing 10. The curved face 38 is provided at a front end portion of the support portion 35. The curved face 38 is curved upward toward the front when the wire cover 30 is in a state of being attached to the housing 10. Each support portion 35 has an outer wall portion 39 that is arranged on the outer side of the curved face 38 (on the right side in the right support portion 35, and on the left side in the left support portion 35). The outer wall portion 39 extends along the side face 16B of the corresponding support receiving portion 16. Each support portion 35 has fitting portions 52. The fitting portions 52 will be described later in detail.

As shown in FIG. 4, the lever 40 has a pair of left and right side plates 41 and a connecting portion 42 that connects ends of the side plates 41 to each other. The pair of left and right side plates 41 have attachment holes 43 to which the respective shafts 33 are fitted. The lever 40 is rotatably attached to the wire cover 30 by fitting the shafts 33 to the attachment holes 43.

The lever 40 is rotatable between a lever initial position, at which the lever 40 is held when fitting to the counterpart connector is initiated, and a lever fitting completion position, at which the lever 40 is held when the fitting to the counterpart connector is complete. FIG. 4 shows the lever 40 arranged at the lever initial position. The lever fitting completion position is a position rotated counterclockwise from the lever fitting completion position in FIG. 4. A gear 44 that meshes with the rack teeth 22 is provided on the outer face of each side plate 41 of the lever 40. The lever 40 moves the sliders 20 through the meshing between the gears 44 and the rack teeth 22.

The fulcrum portions 50 rotatably support the wire cover 30. The fulcrum portions 50 are provided on both the left and right sides of the housing 10. The fulcrum portions 50 are provided at rear end portions of the housing 10. Each fulcrum portions 50 has a protruding portion 51 and a rotation axis portion 53. The protruding portions 51 protrude upward (in a direction intersecting the first direction) from the housing 10.

The protruding portions 51 are provided in the respective support receiving portions 16 of the housing 10, as shown in FIGS. 5 and 6. The protruding portions 51 are walls that are provided at the rear ends of the support receiving portions 16. The protruding portions 51 protrude upward along the rear face of the housing 10 from the bottom faces 16A of the respective support receiving portions 16.

The rotation axis portions 53 are provided at upper end portions of the protruding portions 51. The rotation axis portions 53 serve as the rotation center of the wire cover 30. The rotation axis portions 53 protrude forward from the upper ends of the protruding portions 51.

Corner portions of the surfaces of the rotation axis portions 53 that come into contact with the wire cover 30 have curved faces 56, as shown in FIGS. 5 and 6. The curved faces 56 are provided at the upper and lower side of the front end of each rotation axis portion 53.

As shown in FIGS. 5 and 6, first fitting recessed portions 54 to which the respective fitting portions 52 are fitted are provided below the rotation axis portions 53. The first fitting recessed portions 54 are open on their front side. The depth (size in the front-back direction) of each first fitting recessed portion 54 is larger than the protruding length (size in the front-back direction) of each fitting portion 52. As a result, the rear end of each fitting portion 52 and the rear end of the corresponding first fitting recessed portion 54 are held away from each other in the front-back direction when the first fitting recessed portion 54 is in a state of being fitted to the fitting portion 52. In other words, a gap is formed between the rear end of each fitting portion 52 and the rear end of the corresponding first fitting recessed portion 54.

As shown in FIGS. 5 and 6, the fitting portions 52 are provided in the support portions 35 of the wire cover 30. Each fitting portion 52 is provided at the rear lower end of the corresponding support portion 35. The fitting portions 52 protrude backward along the lower faces of the support portions 35. The fitting portions 52 are fitted to the respective protruding portions 51 from the front (from a direction parallel to the first direction). The fitting portions 52 are fitted to the first fitting recessed portions 54.

As shown in FIGS. 5 and 6, second fitting recessed portions 55, to which the rotation axis portions 53 are fitted, are provided above the fitting portions 52. The second fitting recessed portions 55 are open on their rear side. The upper faces of the second fitting recessed portions 55 extend obliquely upward toward the rear, as shown in FIG. 6. The upper faces of the second fitting recessed portions 55 extend to the vicinity of the wire guide opening 34 of the wire cover 30.

As shown in FIGS. 5 and 6, the positioning portions 60 are provided in the support receiving portions 16. Each positioning portion 60 is provided at a position so that the corresponding fitting portion 52 is located between the positioning portion 60 and the corresponding protruding portion 51. Each positioning portion 60 has a gap S (see FIG. 6) that allows fine adjustment of the position of the wire cover 30 in the front-back direction so that the rack teeth 22 mesh with the gears 44, thus allowing the wire cover 30 to be positioned.

As shown in FIG. 3, each positioning portion 60 is provided in a center area of the corresponding support receiving portions 16 in the left-right direction. The positioning portions 60 protrude upward from the bottom faces 16A of the support receiving portions 16.

As shown in FIGS. 5 and 6, each positioning portion 60 has a positioning face 60A that is curved in the rotational direction of the wire cover 30. The positioning face 60A is curved so as to be located further upward as it extends forward away from the corresponding rotation axis portion 53. The positioning faces 60A are parallel to the curved faces 38 of the support portions 35 when the wire cover 30 is in a state of being attached to the housing 10. The vertical position of the upper end of each positioning face 60A is substantially is the same as the vertical position of the corresponding rotation axis portion 53.

Next, an example of an operation of assembling the lever-type connector C will be described.

First, terminal fittings are put into the housing 10. Specifically, the terminal fittings fastened to terminal portions of the wires W are inserted into the terminal accommodating holes 11 from the wire draw-out surface 12 side of the housing 10. After the terminal fittings have been put into the terminal accommodating holes 11, the wires W are in a state of being pulled out from the wire draw-out surface 12.

Next, the wire cover 30 is attached to the housing 10 (see FIGS. 5 and 6). At this time, the lever 40 is held at the lever initial position relative to the wire cover 30. Each slider 20 is held at the slider initial position relative to the housing 10 in advance. Then, the wire cover 30 is inclined relative to the housing 10 as shown in FIG. 5. The support portions 35 of the wire cover 30 are inserted into the support receiving portions 16 of the housing 10 from obliquely front and above. The fitting portions 52 of the wire cover 30 are shallowly fitted to the first fitting recessed portions 54 of the housing 10 from the front. The fitting portions 52 have a tapered shape due to the inclined faces 36, and are therefore easily fitted to the first fitting recessed portions 54. Meanwhile, the rotation axis portions 53 of the housing 10 are shallowly fitted to the second fitting recessed portions 55. This makes the wire cover 30 to be supported by the housing 10 so as to be rotatable about the rotation axis portions 53. The lower faces of the support portions 35 are separate from and located above the bottom faces 16A of the support receiving portions 16.

Next, the wire cover 30 is rotated forward. The wire cover 30 rotates about the rotation axis portions 53. The position of the wire cover 30 in the front-back direction is finely adjusted while rotating the wire cover 30. The support portions 35 of the wire cover 30 are displaced along the positioning faces 60A of the housing 10. The positions of the support portions 35 of the wire cover 30 in the front-back direction are finely adjusted within the area of the gap S between the support portions 35 and the positioning faces 60A.

The fitting portions 52 are displaced backward along the curved faces 56 of the rotation axis portions 53 and deeply fitted to the first fitting recessed portions 54, as shown in FIG. 6. The upper faces of the fitting portions 52 come into surface contact with the lower faces of the respective rotation axis portions 53. The horizontal faces 37 of the support portions 35 come into surface contact with the bottom faces 16A of the respective support receiving portions 16. The curved faces 38 of the support portions 35 are then arranged above the positioning faces 60A of the respective support receiving portions 16. The support portions 35 coming into contact with the positioning faces 60A cause the gears 44 of the wire cover 30 to be arranged at the position at which they mesh with the rack teeth 22. Accordingly, the gears 44 mesh with the rack teeth 22 without pressing the sliders 20 as a result of coming into contact with the rack teeth 22. After the wire cover 30 has thus reached the normal attachment position, the lock portions 13 of the housing 10 are fitted to the respective lock receiving portions 31 of the wire cover 30. The operation of assembling the lever-type connector C is completed by the above procedure. Note that the inclined faces 36 of the support portions 35 are separate from the bottom faces 16A of the support receiving portions 16 both in the middle of attaching the wire cover 30 and when the attachment is complete.

Next, the operation and effects of the lever-type connector C having the above configuration will be described.

The lever-type connector C has a housing 10, sliders 20, a wire cover 30, a lever 40, fulcrum portions 50, and positioning portions 60. The sliders 20 are movable in the front-back direction (first direction) relative to the housing 10. Each slider 20 has a plurality of rack teeth 22 that are arranged in the front-back direction. The wire cover 30 is installed on the housing 10 and covers the wire draw-out surface 12 of the housing 10. The lever 40 is rotatably installed on the wire cover 30. The lever 40 has gears 44 that mesh with the rack teeth 22 and moves the sliders 20. The fulcrum portions 50 are provided in the housing 10. The fulcrum portions 50 rotatably support the wire cover 30. The positioning portions 60 are provided in the housing 10. The positioning portions 60 come into contact with the wire cover 30 and cause the gears 44 to be located at the positions at which the gears 44 can mesh with the rack teeth 22.

This configuration enables the wire cover 30 to be positioned so that the gears 44 mesh with the rack teeth 22 when the wire cover 30 is rotated while being supported by the fulcrum portions 50. Accordingly, the gears 44 of the wire cover 30 can be prevented from coming into contact with the rack teeth 22 of the sliders 20 and shifting the positions of the sliders 20 when the wire cover 30 is attached to the housing 10.

Each fulcrum portion 50 has a protruding portion 51 that protrudes upward from the housing 10. The wire cover 30 has fitting portions 52 that are fitted to the protruding portions 51 from the rear. The positioning portions 60 are provided at the opposite positions to the protruding portions 51 with the fitting portions 52 therebetween. Each positioning portion 60 has a positioning face 60A that is curved in the rotational direction of the wire cover 30. This configuration enables the wire cover 30 to be easily positioned.

Gear arrangement portions 15, in which the gears 44 are arranged when the wire cover 30 is in a state of being attached to the housing 10, are arranged in a center area of the housing 10 in the front-back direction. Both the protruding portions 51 and the positioning portions 60 are arranged behind the gear arrangement portions 15 in the front-back direction. This configuration enables the housing 10 to be made more compactly than in the case where the protruding portions and the positioning portions are provided on the front and rear sides of the housing 10 in the front-back direction.

Each fulcrum portion 50 has a rotation axis portion 53 serving as a rotation center of the wire cover 30. Corner portions of the surface of each rotation axis portion 53 that come into contact with the wire cover 30 have curved faces 56. This configuration enables the wire cover 30 to be smoothly rotated compared to the case where the corner portions of the surface of each rotation axis portion that come into contact with the wire cover are right-angled.
