Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] The connector of Patent Document 1 includes a housing (housing main body), a cover (wire cover) attached to the housing so as to cover the rear surface of the housing, and a lever rotatably supported on the housing. A slider is attached to the housing. The slider slides relative to the housing in response to rotation of the lever, and engages and disengages the housing with a mating housing (second housing). The housing also contains a plurality of terminal fittings (first terminal fittings). Each terminal fitting is connected to an end portion of an electric wire. The wire cover determines the routing direction of each electric wire drawn out from the rear surface of the housing.

[0003] The lever has a pair of side portions (arm portions) in the width direction and a connecting portion connecting the side portions. The lever is arranged to straddle the cover, with a portion of the side portion located outside the side portion of the cover. The other portion of the side portion is located outside the side portion of the housing. This type of connector is also disclosed in Patent Documents 2 to 4. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-195400 A [Patent Document 2] Japanese Patent Application Laid-Open No. 2007-242251 [Patent Document 3] Japanese Patent Application Laid-Open No. 2008-218302 [Patent Document 4] Japanese Patent Application Laid-Open No. 2011-204494 Summary of the Invention [Problem to be solved by the invention]

[0005] In the connectors of Patent Documents 1 to 4, the width of the lever corresponds to the width of the cover, and the side of the lever is aligned with the side of the cover, so that the cover suppresses deformation of the lever when it rotates.

[0006] When the number of terminal fittings housed in the housing is reduced from the normal number, the number of wires placed inside the cover also decreases, so it is necessary to reduce the width of the cover in order to miniaturize the connector. However, even if the width of the cover and the width of the lever are reduced, the width of the housing does not change, so the width of the lever cannot be changed in the part that overlaps with the housing (other than the side part). This makes the lever design difficult, and there is a risk that it will not be possible to accommodate the miniaturization of the connector.

[0007] Therefore, an object of the present disclosure is to provide a connector that can accommodate miniaturization. [Means for solving the problem]

[0008] The connector of the present disclosure comprises a housing having a wire pull-out surface, a cover attached to the housing so as to cover the pull-out surface, and a lever rotatably supported on the housing, the lever having a pair of side portions opposing each other in the width direction and a connecting portion connecting the pair of side portions, the cover having a pair of cover side portions arranged on the inside of the pair of side portions in the width direction, the housing having a pair of housing side portions arranged alongside the pair of cover side portions at positions opposite the pair of cover side portions across the boundary of the outer periphery of the pull-out surface, and the lever being spaced apart from the pair of housing side portions in the direction of alignment of the cover side portions and the housing side portions. [Effects of the Invention]

[0011] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A housing having a wire pull-out surface, a cover attached to the housing so as to cover the pull-out surface, and a lever rotatably supported on the housing, the lever having a pair of side portions opposing each other in the width direction and a connecting portion connecting the pair of side portions, the cover having a pair of cover side portions arranged inside the pair of side portions in the width direction, the housing having a pair of housing side portions arranged side by side with the pair of cover side portions at positions opposite the pair of cover side portions across the boundary of the outer periphery of the pull-out surface, and the lever being spaced apart from the pair of housing side portions in the direction of alignment of the cover side portions and the housing side portions. According to the above configuration, the width of the lever can be set without being restricted by the side surface of the housing. Therefore, when the number of wires drawn from the drawing surface of the housing is reduced, the width of the cover can be reduced without changing the width of the housing, and the width of the lever can be reduced accordingly. As a result, it is possible to accommodate miniaturization of the connector.

[0012] (2) It is preferable that the lever has a pivot shaft at the base end of the side portion, and the housing has a bearing portion that receives the pivot shaft at a position shifted to one side in a horizontal direction that intersects with the alignment direction relative to the housing side portion. According to the above configuration, the lever length from the rotation shaft to the connecting portion can be made long, so that the lever can be rotated with a small force.

[0013] (3) The base end portion has a shape that extends in the alignment direction across the cover and the housing, and the side portion preferably has a main body portion that extends from a position on the cover side of the base end portion to the other side in the lateral direction. According to the above, the side portion of the lever can be made into a simple shape.

[0014] (4) The pair of cover side portions have a wide portion located closer to the housing in the arrangement direction, a narrow portion that is narrower than the wide portion and located farther from the housing, and a step portion located between the wide portion and the narrow portion, and the main body portion is preferably arranged along the narrow portion. According to the above configuration, the width of the lever can be reduced by the width of the narrow portion, thereby realizing a miniaturized connector.

[0015] (5) When the housing and the mating housing are in a mated state, the main body portion preferably faces the step portion so as to be able to come into contact with it. According to the above configuration, when the housing and the mating housing are mated, the main body contacts the step portion, stopping the rotation of the lever. In addition, the contact of the main body with the step portion can prevent the cover from deforming at the step portion.

[0016] (6) The step portion may have a recess recessed in the arrangement direction, and the main body portion may have a protrusion that fits into the recess in the fitted state. According to the above configuration, when the housing and the mating housing are in a mated state, it is possible to prevent the lever from shifting position relative to the housing.

[0017] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0018] <Embodiment 1> As shown in FIGS. 1 and 2, a connector 10 according to a first embodiment of the present disclosure includes a housing 11, a slider 40, a cover 50, a lever 70, and a terminal fitting 90. As shown in FIG. 3, the housing 11 is matable with a mating housing 100. In the following description, the front side of the housing 11 mated with the mating housing 100 is referred to as the front side in the front-to-rear direction. The lower side in FIGS. 2 and 3 corresponds to the front side. The width direction is the thickness direction of the paper in FIGS. 2 and 3 and corresponds to the left-to-right direction in FIG. 4. The lateral direction is a direction intersecting the front-to-rear direction and the width direction and corresponds to the left-to-right direction in FIGS. 2 and 3. One lateral side corresponds to the right side in FIGS. 2 and 3, and the other lateral side corresponds to the left side in FIGS. 2 and 3. In FIGS. 1 to 4 and 9, the front side is indicated by the symbol F, the rear side by the symbol R, one lateral side by the symbol H1 (not shown in FIGS. 4 and 9), and the other lateral side by the symbol H2. 1, 4, and 9, the width direction is indicated by the symbol W. In the following description, illustrations of elements that are less relevant to the contents of this disclosure are omitted.

[0019] (housing, terminal fittings, etc.) The housing 11 is made of synthetic resin, and includes an outer housing 12, an inner housing 13, a retainer 14, and a front mask 15, as shown in FIG.

[0020] The inner housing 13 has a rectangular block shape that is elongated in the horizontal direction. A rubber seal ring 20 is attached to the outer periphery of the inner housing 13. When the housing 11 and the mating housing 100 are mated, the seal ring 20 is sandwiched between the inner housing 13 and the mating housing 100, creating a liquid-tight seal between the housing 11 and the mating housing 100. A rubber one-piece rubber stopper 30 is attached to the rear end of the inner housing 13. The one-piece rubber stopper 30 is sandwiched between the inner housing 13 and a rear wall 18 (described below) of the outer housing 12. The inner housing 13 is formed with a plurality of cavities 16 that extend in the front-to-rear direction.

[0021] The terminal fittings 90 are inserted from the rear into the respective cavities 16 of the inner housing 13 and accommodated therein. The terminal fittings 90 are made of conductive metal and are connected by crimping to the terminal portions of the electric wires W. The electric wires W pass through the lump-type rubber plugs 30 in a liquid-tight manner and are drawn out rearward from a drawing surface 27 of the outer housing 12, which will be described later.

[0022] The retainer 14 is attached to the inner housing 13 and locks the terminal fittings 90. The retainer 14 prevents the terminal fittings 90 from coming out of the inner housing 13. The front mask 15 is attached to the inner housing 13 so as to cover the front surface of the inner housing 13. Each of the cavities 16 of the inner housing 13 also coaxially passes through the front mask 15.

[0023] The outer housing 12 has a rectangular box shape that is elongated in the horizontal direction. The outer housing 12 has a peripheral wall 17 that surrounds the outer periphery and a rear wall 18 that closes the rear end, and is open forward. The rear wall 18 prevents the one-piece rubber plug 30 from slipping out of the inner housing 13. The inner housing 13 is inserted from the front into the interior of the outer housing 12 (the internal space between the peripheral wall 17 and the rear wall 18) and accommodated therein. As shown in FIG. 6 , a locking hole 19 is formed in the peripheral wall 17 of the outer housing 12. The inner housing 13 is prevented from slipping out of the outer housing 12 by fitting a locking projection 21 (see FIG. 1 ) that protrudes laterally into the locking hole 19.

[0024] A hood portion 101 of a mating housing 100 is fitted between the peripheral wall 17 of the outer housing 12 and the inner housing 13 . The peripheral wall 17 is composed of a pair of housing side surface portions 22 (see FIG. 4, only one is shown in FIG. 6) facing each other in the width direction, and a pair of housing end surface portions 23 (only one is shown in FIGS. 4 and 6) facing each other in the lateral direction. As shown in FIG. 4, an insertion hole 24 that is long in the front-rear direction is formed at both ends in the width direction of each housing end surface portion 23. A slider 40 is housed in the insertion hole 24.

[0025] An insertion space 25 (see FIG. 5) communicating with the insertion hole 24 is formed inside the outer housing 12. The slider 40 is inserted into the insertion space 25 from the insertion hole 24 on one side in the lateral direction. The inner surface on the inner side in the width direction (the surface facing the insertion space 25) and the outer surface on the outer side in the width direction of each housing side portion 22 are formed flat along the lateral direction and the front-rear direction, respectively (see FIG. 4).

[0026] As shown in FIG. 6 , the rear wall 18 has a plurality of through holes 26. Electric wires W extending from the one-piece rubber plug 30 are disposed through each through hole 26. The rear wall 18 has a rearward-facing rear surface, which defines a lead-out surface 27 through which the electric wires W are led out. The rear wall 18 has slide portions 28 at the outer periphery of the lead-out surface 27, at the boundary between the lead-out surface 27 and the housing side surface 22. The slide portions 28 are formed in pairs at both widthwise ends of the rear surface of the rear wall 18. The slide portions 28 each have a groove 31 extending laterally and a plurality of eave-shaped retaining portions 32 that partially close the groove 31. As shown in FIG. 5 , guide portions 61 (described later) of the cover 50 are slidably inserted into the grooves 31 of the slide portion 28. Each retaining portion 32 engages with the guide portion 61 to prevent the cover 50 from coming out of the outer housing 12.

[0027] As shown in Figures 1 and 6, the outer housing 12 has an extension 33 at its front end that is laterally offset to one side relative to the peripheral wall 17. The outer housing 12 also has a support 34 that protrudes rearward from the extension 33. As shown in Figure 6, the support 34 has a pair of bearings 35 formed in the width direction. Each bearing 35 has a U-shaped cross section and is open rearward. A pivot 82 (see Figure 3), which will be described later, of the lever 70 is rotatably inserted into each bearing 35.

[0028] (Slider 40) 1, the sliders 40 are made of synthetic resin and have the shape of horizontally long plates, and are attached in pairs to the housing 11 so as to correspond to the respective widthwise insertion holes 24. The sliders 40 are slidable in the horizontal direction relative to the housing 11 along the inner surface of the housing side portion 22.

[0029] Cam grooves 41 are recessed at multiple locations spaced apart in the horizontal direction on the inner surface (opposing surface) of the slider 40. Each cam groove 41 extends in a diagonal direction intersecting the horizontal direction and opens at the front end of the slider 40. As shown in FIG. 5 , a cam pin 102 formed on a hood portion 101 of the mating housing 100 is inserted into each cam groove 41. When the slider 40 moves, each cam pin 102 slides on the groove surface of each cam groove 41, thereby enabling the housing 11 and the mating housing 100 to be fitted together and separated from each other.

[0030] As shown in Fig. 1, a pressure receiving portion 43 is recessed at one lateral end of the inner surface of slider 40. Pressure receiving portion 43 has a U-shaped cross section and is open rearward. As shown in Figs. 2 and 3, when slider 40 is attached to housing 11, pressure receiving portion 43 is positioned offset to one lateral side with respect to housing side surface portion 22. A pressing portion 81 of lever 70, which will be described later, is inserted into pressure receiving portion 43 so as to be able to be pressed laterally.

[0031] (cover) The cover 50 is made of synthetic resin, has a cap shape, and is open across one lateral side and the front. As shown in FIG. 7 , the cover 50 has a pair of cover side portions 51 in the width direction and a back portion 52 connecting the rear ends of the cover side portions 51. The back portion 52 closes the other lateral end face and the rear end face of the cover 50. Each electric wire W drawn out from the drawing surface 27 of the housing 11 is bent toward one lateral side by the back portion 52 inside the cover 50. Each electric wire W is then drawn out from a drawing end at the end of one lateral side of the cover 50. The outer periphery of the drawing end of the cover 50 is bordered by a rib 53. Although not shown in detail, an elastically deformable locking arm 54 is formed on the other lateral end face of the back portion 52 (see FIGS. 2 and 7 ).

[0032] When the cover 50 is attached to the housing 11, the cover side portion 51 and the housing side portion 22 are arranged side by side in the front-to-rear direction, with the slide portion 28 as a boundary therebetween. The cover 50 has a wide portion 55 on the front end side closer to the housing 11, a narrow portion 56 on the rear end side away from the housing 11, and a step portion 57 along the width direction between the narrow portion 56 and the wide portion 55. The wide portion 55, the narrow portion 56, and the step portion 57 are the portions of the outer surface of each cover side portion 51 that make up the maximum width of the cover 50. As shown in FIG. 4, the width dimension of the narrow portion 56 (see d1 in FIG. 4) is smaller than the width dimension of the wide portion 55.

[0033] 2, when viewed from the outside in the width direction, the step portion 57 has a linear portion 58 extending laterally and a recessed portion 59 recessed forward adjacent to the linear portion 58. The recessed portion 59 has a bottom surface portion extending laterally.

[0034] As shown in FIG. 7 , the cover 50 has a guide portion 61 extending laterally on the inner surface of the front end of each cover side portion 51, opposite the wide portion 55. As shown in FIG. 5 , the guide portion 61 is slidably fitted into the groove portion 31 of the slide portion 28. The lever 70 also has an elastically deformable cover lock portion 62 at a position facing the guide portion 61. As shown in FIG. 7 , the cover lock portion 62 is exposed at the wide portion 55 and the stepped portion 57. As shown in FIG. 5 , the cover lock portion 62 is engaged with the retaining portion 32, thereby restricting the cover 50 from shifting laterally to the other side (left side in FIG. 5 ) relative to the outer housing 12. The displacement of the cover 50 relative to the outer housing 12 (right side in FIG. 5 ) is restricted by the retaining portion 32 engaging a portion of the wide portion 55.

[0035] (lever) The lever 70 is made of synthetic resin and has a rectangular frame shape, and is supported rotatably between a start position (see FIG. 2) and a mating position (see FIG. 3) relative to the housing 11. In the following description, the direction of the lever 70 is determined based on the state in which the lever 70 is disposed at the mating position relative to the housing 11.

[0036] 8, the lever 70 has a connecting portion 71 extending in the width direction, a pair of side portions 72 extending laterally from both ends of the connecting portion 71 in the width direction, and a pair of base ends 73 extending forward from the end of each side portion 72 in the width direction. The connecting portions of the side portions 72 and the base ends 73 intersect in an L-shape.

[0037] A lever lock portion 74 that is engaged with the lock arm 54 is formed on the inner surface (the surface facing forward) of the connecting portion 71. The inner surfaces (inner surfaces in the width direction) of the side portions 72 are arranged along the lateral and longitudinal directions. The distance between the inner surfaces of the side portions 72 (the distance between the inner surfaces) is set to correspond to the width of the narrow portion 56.

[0038] Each side portion 72 has an inclined portion 75 that slopes forward from the connecting portion 71 toward one side in the horizontal direction and a main portion 76 that extends from the inclined portion 75 to the base end 73 in the horizontal direction. The main portion 76 has a plurality of laterally extending edge portions 77 at its front end and a protrusion 78 that protrudes forward at a laterally intermediate portion of the main portion 76 between adjacent edge portions 77. The protrusion 78 has a trapezoidal shape and an end surface that extends laterally. As shown in FIG. 3, the protrusion 78 is fitted into the recess 59 at the mating position. The main portion 76 has a triangular recessed groove 79 at its rear end at a position corresponding to the protrusion 78. As shown in FIG. 2, the groove 79 engages with the rib 53 of the cover 50 at the starting position. The protrusion 78 reinforces the laterally intermediate portion of the side portion 72, which would otherwise be weakened by the formation of the recess 79.

[0039] As shown in Fig. 8, each base end 73 is connected to each main body 76 and shifted inward in the width direction. The outer surface (the outer surface in the width direction) of each base end 73 is disposed widthwise inward relative to the outer surface of each main body 76. A pair of pressing portions 81 (only one is shown in Fig. 8) protrudes from the rear end of the outer surface of each base end 73. The tip end (the outer end in the width direction) of each pressing portion 81 in the protruding direction has a circular cam shape and presses the corresponding pressure receiving portion 43 of the slider 40, allowing the slider 40 to slide relative to the housing 11.

[0040] A pair of rotary shafts 82 protrude from the front end of the inner surface (the inner surface in the width direction) of each base end portion 73. The rotary shafts 82 are cylindrical and arranged opposite each other. The rotary shafts 82 are rotatably inserted into the respective bearing portions 35.

[0041] A pair of restricting portions 83 protrude from the middle of the inner surface of each base end portion 73 in the front-rear direction. The restricting portions 83 are rectangular plate-shaped and arranged opposite each other. The protruding tips of the restricting portions 83 are engaged with each other in a concave-convex manner. The restricting portions 83 are engaged with each other to restrict the positional deviation of the side portions 72 in the front-rear direction.

[0042] (Connector function) Prior to fitting the housing 11 and the mating housing 100 together, the pivot shaft 82 is fitted into and supported by the bearing portion 35, the pressing portion 81 is received by the pressure receiving portion 43, and the lever 70 is supported in the starting position relative to the housing 11. As shown in FIG. 2 , the lever 70 is positioned relative to the cover 50 at the starting position by fitting the end of the rib 53 into the recessed groove 79. Furthermore, at the starting position, the lever 70 is positioned so that it is shifted laterally to one side relative to the housing side surface portion 22 as a whole.

[0043] Next, the mating housing 100 is shallowly fitted into the housing 11. As a result, the cam pins 102 of the mating housing 100 are inserted into the entrances of the cam grooves 41 of the slider 40. In this state, the lever 70 is rotated relative to the housing 11 around the rotation shaft 82 in the direction of arrow A in FIG. 2 toward the mating position. The operator can smoothly rotate the lever 70 by grasping the connecting portion 71.

[0044] As the lever 70 moves toward the mating position, the pressing portion 81 presses the pressure receiving portion 43, and the slider 40 slides laterally toward the other side relative to the housing 11. During this time, the cam pins 102 slide along the groove surfaces of the cam grooves 41, and the mating of the housing 11 and the mating housing 100 progresses.

[0045] When the lever 70 reaches the mating position, the lever lock portion 74 engages with the lock arm 54 of the cover 50, stopping the rotation of the lever 70. The cam pins 102 reach the inner ends of the cam grooves 41, and the housing 11 and the mating housing 100 are properly mated. The terminal fittings 90 are electrically connected to mating terminals (not shown) attached to the mating housing 100.

[0046] 3, when the lever 70 reaches the mating position, the front end of the main body 76 of the side portion 72 rests on the stepped portion 57 of the cover 50, and the edge portion 77 comes into contact with the straight portion 58. This restricts further rotation of the lever 70, and the lever 70 is stopped at the mating position. Furthermore, at the mating position, the convex portion 78 of the lever 70 fits into the concave portion 59 of the cover 50, restricting misalignment of the lever 70 with respect to the cover 50.

[0047] Furthermore, in the mated position, the lever 70, excluding the base ends 73, is disposed along the outer surface of the cover 50. Specifically, the side portions 72 are disposed along the narrow portions 56 of the cover side surfaces 51, and the connecting portion 71 is disposed along the rear surface 52. The base ends 73 are disposed on one lateral side of the housing side surfaces 22, side by side with the housing side surfaces 22. A portion of each base end 73 is disposed inside the slider 40 in the width direction. On the other hand, the lever 70 does not have a portion that overlaps (covers) the housing side surfaces 22, and is disposed entirely rearward and away from the housing side surfaces 22 in the arrangement direction of the housing 11 and the cover 50.

[0048] The above case assumes a configuration in which terminal fittings 90 are housed in all of the cavities 16 of the inner housing 13. In this configuration, as shown in Fig. 4, the lever 70 is set to have a width D1, and the cover 50 is set to have a width d1. In contrast, in a configuration in which the terminal fittings 90 are housed in only a portion of each cavity 16 of the inner housing 13, the number of wires W arranged inside the cover 50 will be reduced from the above. Here, if the width dimensions of the cover 50 and the lever 70 can be reduced, the connector 10 can be made smaller, which is considered to be preferable.

[0049] In this regard, in the first embodiment, the entire lever 70 is disposed rearward and away from the housing side surfaces 22, and the width of the lever 70 can be determined independently of the dimension between the outer surfaces of the housing side surfaces 22 at the widthwise outer sides, i.e., the width of the housing 11. In other words, the width of the lever 70 can be determined simply by matching the dimension between the inner surfaces of the side surfaces 72 with the dimension between the outer surfaces of the cover side surfaces 51 at the widthwise outer sides (the width of the narrow portions 56). 9, the width dimension d2 of the cover 50 is reduced without changing the width dimension of the housing 11, and the width dimension D2 of the lever 70 can be reduced by the amount of the reduction in the width dimension d2 of the cover 50. As a result, the width dimension D2 of the lever 70 can be made smaller than the width dimension D1 (see FIG. 4), and the width dimension d2 of the cover 50 can be made smaller than the width dimension d1, thereby making it possible to reduce the size of the connector 10 on the rear side where the lever 70 and the cover 50 are located.

[0050] As described above, according to the first embodiment, the width of the lever 70 can be set without being restricted by the housing side surface portions 22. Therefore, when the number of electric wires W is reduced, the width of the cover 50 can be reduced without changing the width of the housing 11, and the width of the lever 70 can be further reduced in accordance with the cover 50. As a result, it is possible to accommodate miniaturization of the connector 10.

[0051] Furthermore, in the case of the first embodiment, the lever 70 has a shape that extends long from the rotation shaft 82 to the connecting portion 71 so as not to overlap with the housing side surface portion 22. This allows the overall length of the lever 70 to be long, and the lever 70 can be rotated with a small force.

[0052] In addition, the side portion 72 has a main body portion 76 extending laterally from the rear end side of the base end portion 73 to the other side, and when the lever 70 is in the mating position, the main body portion 76 faces the step portion 57 so as to be able to come into contact with it, so that the main body portion 76 can prevent the cover 50 from deforming on the step portion 57 side.

[0053] Furthermore, the step portion 57 has a recess 59 that is recessed forward, and the main body portion 76 has a protrusion 78, and when the lever 70 is in the mating position, the protrusion 78 fits into the recess 59, thereby restricting the positional deviation of the lever 70 relative to the housing 11.

[0054] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, the lever is configured as an operating lever that moves a slider having a cam groove. In contrast, in other embodiments, the lever may have a force-boosting structure such as a cam groove to engage the housing with the mating housing. In the first embodiment, the housing is configured to include an inner housing and an outer housing. In contrast, in another embodiment, the housing may have an inseparable, one-piece structure. In another embodiment, a housing side surface may be formed on the outer surface of the housing in the width direction, in a position aligned with the cover side surface in the front-rear direction.
