DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. [1] The connector disclosed herein comprises an outer housing, at least one inner housing inserted into the outer housing from one side in a first direction, and a wire cover accommodating electric wires leading out from the inner housing, the wire cover being attached to the one side in the first direction of the outer housing, and the wire cover having an abutment portion abutting the inner housing from the one side in the first direction.

[0009] According to this configuration, if the inner housing is partially inserted into the outer housing, the inner housing is pushed into the outer housing by the abutment portion when the wire cover is attached to the outer housing, thereby making it possible to prevent the inner housing from being partially inserted into the outer housing.

[0010] [2] In the above [1], it is preferable that one of the wire cover and the outer housing includes a first wall portion and a protrusion protruding from the first wall portion in a second direction perpendicular to the first direction, and the other of the wire cover and the outer housing includes a second wall portion having a portion facing the first wall portion in the second direction, and a protrusion receiving portion recessed from the second wall portion in the second direction, and the protrusion receiving portion extends in a third direction perpendicular to the first direction and the second direction to receive the protrusion.

[0011] According to this configuration, the wire cover can be attached to the outer housing by sliding the protrusion and the protrusion receiving portion against each other.

[0012] [3] In the above [1] or [2], it is preferable that the contact portion includes a first contact portion and a second contact portion protruding from the first contact portion to the other side in the first direction.

[0013] With this configuration, the gap between the wire cover and the inner housing can be reduced, and rattling of the inner housing can be suppressed.

[0014] [4] In the above [2], it is preferable that the abutment portion comprises a first abutment portion and a second abutment portion protruding from the first abutment portion to the other side in the first direction, the second abutment portion extends in the third direction, the second abutment portion has an inclined portion at an end portion on one side in the third direction, and the inclined portion has a protruding dimension from the first abutment portion that increases toward the other side in the third direction.

[0015] According to this configuration, the gap between the wire cover and the inner housing can be smoothly filled by sliding the wire cover to one side in the third direction.

[0016] [5] In any one of [1] to [4] above, it is preferable that the inner housing has an abutment surface that abuts against the abutment portion and an opposing surface that is arranged opposite the wire cover in a direction perpendicular to the first direction, and that the abutment surface and the opposing surface are arranged continuously.

[0017] According to this configuration, the wire cover can be positioned in a direction perpendicular to the first direction by the opposing surface.

[0018] [6] The connector according to any one of [1] to [5] above may include a plurality of the inner housings.

The present disclosure is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope of the claims. In each drawing, for convenience of explanation, some of the configurations may be exaggerated or simplified. In addition, the dimensional ratios of each part may differ in each drawing. In this specification, "orthogonal" does not only mean strictly orthogonal, but also includes roughly orthogonal within the range in which the action and effect of this embodiment are achieved.

[0020] In addition, the term "cylindrical" used in the description of this specification does not only refer to a cylindrical shape having a continuous wall formed around the entire circumference, but also includes a cylindrical shape formed by combining multiple parts, and a C-shape having a notch in a part of the circumference. In addition, the shape of a "cylindrical shape" includes a circle, an ellipse, and a polygon with sharp or rounded corners.

[0021] In addition, "facing" in this specification refers to surfaces or members facing each other, and includes not only cases where they are completely facing each other, but also cases where they are partially facing each other. In addition, "facing" in this specification includes both cases where a member other than the two parts is interposed between the two parts, and cases where nothing is interposed between the two parts.

[0022] <Embodiment> An embodiment of the present disclosure will be described with reference to Figures 1 to 15. In the following description, the direction indicated by the arrow Z is the upward direction, the direction indicated by the arrow X is the forward direction, and the direction indicated by the arrow Y is the leftward direction. Note that, for multiple identical members, only some of the members may be labeled with reference numerals, and the reference numerals of the other members may be omitted.

[0023] (Connector 10) 1 and 2, the connector 10 includes a plurality of inner housings 20, an outer housing 30, and a wire cover 40. The connector 10 is adapted to mate with a mating connector (not shown).

[0024] The connector 10 of this embodiment is a lever-type connector. As shown in Fig. 1, the connector 10 includes a lever 11 and a gear 12 that rotates in conjunction with the rotation of the lever 11. Although not described in detail, the lever 11 and the gear 12 are rotatably supported by an outer housing 30. A pinion is formed on each of the lever 11 and the gear 12. The pinion meshes with a rack formed on the mating connector, thereby assisting in mating and disengagement between the connector 10 and the mating connector.

[0025] (Inner housing 20) The inner housing 20 is made of insulating synthetic resin. As shown in FIG. 12, the inner housing 20 includes a main body 21 and a flange 22. The main body 21 has a substantially rectangular parallelepiped shape. A plurality of terminal accommodating portions 21A are formed in the main body 21. The terminal accommodating portion 21A opens in the vertical direction. As shown in FIG. 6, the terminal 13 is accommodated in the terminal accommodating portion 21A. The terminal 13 to which the electric wire 14 is previously connected is inserted from above into the terminal accommodating portion 21A. The electric wire 14 is led out upward from the terminal accommodating portion 21A. The upper surface of the main body 21 is an electric wire lead-out surface 21B. The number and shape of the terminal accommodating portions 21A, the arrangement in the main body 21, and the like may be different or the same among the plurality of inner housings 20. Note that in the drawings, only some of the terminals 13 and the electric wires 14 are illustrated.

[0026] As shown in Fig. 12, the flange portion 22 expands in diameter in a direction perpendicular to the up-down direction from the main body portion 21. The flange portion 22 is disposed at a position near the upper end portion of the main body portion 21. The upper surface 22A of the flange portion 22 is disposed below the electric wire leading-out surface 21B. The upper surface 22A of the flange portion 22 and the electric wire leading-out surface 21B are connected in a stepped manner via the outer peripheral surface 21C of the main body portion 21 extending in the up-down direction. The flange portion 22 includes a lock receiving portion 23 recessed downward from the upper surface 22A of the flange portion 22.

[0027] (Outer housing 30) The outer housing 30 is made of insulating synthetic resin. As shown in FIG. 13, the outer housing 30 includes a plurality of inner accommodating sections 31 and a cover holding wall 32 (an example of a second wall section). The inner accommodating section 31 is tubular and opens in the vertical direction. The plurality of inner accommodating sections 31 are arranged side by side in the front-rear direction and the left-right direction. The inner accommodating section 31 includes a peripheral wall 31A, a locking piece 31B formed by cutting out the peripheral wall 31A, and a locking protrusion 31C protruding from the peripheral wall 31A toward the inside of the inner accommodating section 31. The lower end of the locking piece 31B is a base end connected to the peripheral wall 31A. The locking piece 31B is configured to be flexible and deformable in the left-right direction. A locking protrusion 31B1 protruding from the locking piece 31B toward the inside of the inner accommodating section 31 is formed at the upper end of the locking piece 31B. The locking protrusion 31C is disposed at a position near the lower end of the peripheral wall 31A.

[0028] As shown in Figs. 3, 4, 6, and 14, the inner housing 20 is accommodated inside the inner accommodating portion 31. The inner housing 20 is inserted into the inner accommodating portion 31 from above (one example of one side in the first direction). The locking piece 31B engages with the flange portion 22, causing it to bend and deform outward from the inner accommodating portion 31. When the inner housing 20 is accommodated in the normal position of the inner accommodating portion 31, as shown in Fig. 3, the locking piece 31B returns to its natural state, and the lock receiving portion 23 and the locking projection 31B1 are engaged. Also, as shown in Fig. 4, the lower surface 22B of the flange portion 22 abuts against the engaging protrusion 31C. This allows the inner housing 20 to be held in the inner accommodating portion 31.

[0029] (Protrusion receiving portion 33) As shown in FIG. 13, the cover holding wall 32 is disposed on both the left and right sides of the inner housing portions 31. The cover holding wall 32 is provided so as to be continuous with the inner housing portions 31, and has a portion extending upward beyond the inner housing portions 31. A plurality of protrusion receiving portions 33 are formed at a position near the upper end of the cover holding wall 32. As shown in FIG. 4, the protrusion receiving portion 33 is recessed from the cover holding wall 32 in the left-right direction (an example of a second direction). In detail, the protrusion receiving portion 33 is recessed from the cover holding wall 32 toward the outside of the outer housing 30 in the left-right direction. The protrusion receiving portion 33 is groove-shaped extending in the front-rear direction (an example of a third direction). The protrusion receiving portion 33 includes a first side surface 33A, a second side surface 33B disposed below the first side surface 33A, and a bottom surface 33C connecting the first side surface 33A and the second side surface 33B.

[0030] 8 and 9, the second side surface 33B includes a portion that does not overlap with the first side surface 33A in the up-down direction. The multiple protrusion receiving portions 33 are arranged at intervals in the front-rear direction. A communication space 34 that communicates with the internal space of the protrusion receiving portion 33 is formed behind the protrusion receiving portion 33. The communication space 34 opens upward.

[0031] 13 , the outer housing 30 has an entrance recess 35 and a cover lock receiving portion 36 recessed from the outer surface of the cover holding wall 32 opposite the protrusion receiving portion 33. The entrance recess 35 and the cover lock receiving portion 36 are disposed toward the front end portion of the outer housing 30. The cover lock receiving portion 36 is disposed forward of the entrance recess 35.

[0032] (wire cover 40) The wire cover 40 is made of insulating synthetic resin. As shown in Fig. 1, the wire cover 40 is attached to the upper end of the outer housing 30. As shown in Fig. 6, the wire cover 40 covers the wire lead-out surface 21B from above and protects the wires 14 led out from the wire lead-out surface 21B. The wires 14 are led out to the outside of the connector 10 from an opening 15 formed by the wire cover 40 and the outer housing 30. The opening 15 opens forward.

[0033] As shown in FIG. 15, the wire cover 40 includes a main wall 41 and two side walls 42 (an example of a first wall portion) extending from the main wall 41. The main wall 41 has a shallow U-shaped groove shape as a whole. In a side view, the main wall 41 has a gently curved shape while bulging upward. The two side walls 42 extend from two side edges of the main wall 41, respectively, and are disposed opposite to each other. As shown in FIG. 6, the rear end of the main wall 41 and the rear end of the side walls 42 coincide with each other. The front end of the main wall 41 is disposed at a position rearward of the front end of the side walls 42 and close to the front end of the side walls 42.

[0034] (Protrusion 43) As shown in Fig. 15, the wire cover 40 has a protruding portion 43 protruding in the left-right direction from the side wall 42. In detail, the protruding portion 43 protrudes outward from the wire cover 40 in the left-right direction (opposite the main wall 41 in the left-right direction). The protruding portion 43 extends from the lower end of the side wall 42. The protruding portion 43 extends in the front-rear direction. As shown in Fig. 4, the protruding portion 43 is disposed inside the protruding portion receiving portion 33 and contacts the first side surface 33A, the second side surface 33B, and the bottom surface 33C. This positions the wire cover 40 in the up-down direction and the left-right direction with respect to the outer housing 30.

[0035] As shown in FIG. 15, the wire cover 40 includes a lock protection wall 44 extending from the side wall 42, and a cover lock piece 45 formed between the lock protection wall 44 and the side wall 42. The lock protection wall 44 extends outward from the wire cover 40 in the left-right direction and downward. The cover lock piece 45 is deformable in the left-right direction. The cover lock piece 45 extends in the front-rear direction. The rear end of the cover lock piece 45 is a base end connected to the lock protection wall 44. A cover lock protrusion 45A is formed at the front end of the cover lock piece 45, protruding from the cover lock piece 45 toward the inside of the wire cover 40. As shown in FIG. 5, the cover lock protrusion 45A is adapted to be engaged with the cover lock receiving portion 36. This positions the wire cover 40 in the front-rear direction relative to the outer housing 30.

[0036] (Abutting part 46) As shown in FIG. 15, the wire cover 40 has an abutment portion 46 at the lower end of the side wall 42. As shown in FIG. 4, the abutment portion 46 abuts against the upper surface 22A (one example of an abutment surface) of the flange portion 22 from above. Therefore, when the inner housing 20 is in a half-inserted state in which it is disposed above the normal position with respect to the outer housing 30, when the wire cover 40 is attached to the upper end of the outer housing 30, the abutment portion 46 abuts against the upper surface 22A of the flange portion 22. As a result, the inner housing 20 is pushed downward with respect to the outer housing 30, and the inner housing 20 is inserted into the normal position. Therefore, in the connector 10, it is possible to prevent the inner housing 20 from being disposed in a half-inserted state with respect to the outer housing 30.

[0037] A surface of the lower end of the side wall 42 disposed on the inside of the wire cover 40 faces in the left-right direction an outer peripheral surface 21C (an example of an opposing surface) of the main body 21. This allows the wire cover 40 to be positioned in the left-right direction when the wire cover 40 is attached to the outer housing 30.

[0038] (First contact part 46A, second contact part 46B) 7 and 11, the contact portion 46 includes a first contact portion 46A and a second contact portion 46B that protrudes downward (an example of the other side in the first direction) from the first contact portion 46A. The protruding dimension of the second contact portion 46B from the first contact portion 46A is set in consideration of the size of a vertical gap that may be formed between the wire cover 40 and the inner housing 20. That is, the second contact portion 46B is formed so that this gap is filled by the second contact portion 46B. By providing the second contact portion 46B, rattling of the inner housing 20 with respect to the outer housing 30 can be suppressed.

[0039] (Sloped part 46B1) In this embodiment, the second contact portion 46B extends in the front-rear direction, and an inclined portion 46B1 is formed at a front end portion (one example of an end portion on one side in the third direction) of the second contact portion 46B. The inclined portion 46B1 protrudes from the first contact portion 46A in a larger dimension toward the rear (one example of the other side in the third direction).

[0040] (Assembly of connector 10) The following describes an example of a method for assembling the connector 10. First, the terminals 13 to which the electric wires 14 are connected are accommodated in the terminal accommodating portions 21A of the inner housing 20.

[0041] The inner housing 20 is inserted from above into the inner accommodating portion 31 of the outer housing 30. When the inner housing 20 is inserted into the correct position in the outer housing 30, the lock receiving portion 23 and the lock protrusion 31B1 are engaged, and the lower surface 22B of the flange portion 22 comes into contact with the locking protrusion 31C.

[0042] The lever 11 and the gear 12 are assembled to the outer housing 30 (see FIG. 14).

[0043] Finally, a process of attaching the electric wire cover 40 to the upper end of the outer housing 30 is performed. First, in a state in which the protrusion 43 is disposed above the communication space 34, the electric wire cover 40 is moved downward relative to the outer housing 30, thereby disposing the electric wire cover 40 at a first position relative to the outer housing 30 (see FIG. 9). When the electric wire cover 40 is at the first position, the protrusion 43 is disposed in the communication space 34 and is in a state of abutting against the second side surface 33B of the protrusion receiving portion 33. As shown in FIG. 10, the cover lock protrusion 45A is disposed in the entry recess 35. Also, as shown in FIG. 11, the first abutment portion 46A faces or abuts against the upper surface 22A of the flange portion 22 in the vertical direction, and the second abutment portion 46B is disposed inside the lock receiving portion 23.

[0044] If the inner housing 20 is partially inserted into the outer housing 30, the first contact portion 46A comes into contact with the upper surface 22A of the flange portion 22 during the process of moving the wire cover 40 to the first position. This makes it possible to detect partial insertion of the inner housing 20. Furthermore, by moving the wire cover 40 to the first position with the first contact portion 46A in contact with the upper surface 22A of the flange portion 22, the inner housing 20 is pushed into the correct position in the outer housing 30 by the wire cover 40.

[0045] Next, the wire cover 40 is slid forward from the first position. As a result, the protrusion 43 enters the inside of the protrusion receiving portion 33 and comes into sliding contact with the first side surface 33A, the second side surface 33B, and the bottom surface 33C (see FIGS. 4 and 8). The sliding contact between the protrusion 43 and the protrusion receiving portion 33 makes it easier to slide the wire cover 40 forward.

[0046] When the wire cover 40 moves forward, the cover lock projections 45A come out of the entry recesses 35 and engage with the cover holding wall 32. This causes the cover lock pieces 45 to bend and deform outward from the wire cover 40. When the wire cover 40 further moves forward and is disposed in the second position relative to the outer housing 30, the cover lock projections 45A are disposed in the cover lock receiving portions 36 (see FIG. 5). In this state, the cover lock pieces 45 have returned to their natural state, and the cover lock projections 45A and the cover lock receiving portions 36 are engaged with each other. This completes the attachment of the wire cover 40 to the outer housing 30.

[0047] When the electric wire cover 40 moves forward from the first position, the second abutment portion 46B moves to the outside of the lock receiving portion 23 and slides against the upper surface 22A of the flange portion 22. Since the inclined portion 46B1 is provided at the front end of the second abutment portion 46B, when the electric wire cover 40 is moved forward from the first position, the second abutment portion 46B is prevented from being caught on the step between the lock receiving portion 23 and the upper surface 22A of the flange portion 22. Therefore, the electric wire cover 40 can be moved smoothly from the first position to the second position. When the electric wire cover 40 is disposed at the second position, the second abutment portion 46B abuts against the upper surface 22A of the flange portion 22 (see FIG. 7). This fills the gap between the inner housing 20 and the electric wire cover 40 in the vertical direction, and prevents the inner housing 20 from rattling.

[0048] (Effects of the embodiment) (1-1) A connector 10 according to an embodiment includes an outer housing 30, at least one inner housing 20 inserted into the outer housing 30 from one side (above) in a first direction, and a wire cover 40 that accommodates electric wires 14 leading out from the inner housing 20, the wire cover 40 being attached to one side of the outer housing 30 in the first direction, and the wire cover 40 including an abutment portion 46 that abuts against the inner housing 20 from one side in the first direction.

[0049] According to this configuration, when the inner housing 20 is partially inserted into the outer housing 30, the inner housing 20 is pushed into the outer housing 30 by the abutting portion 46 when the wire cover 40 is attached to the outer housing 30. Therefore, partial insertion of the inner housing 20 into the outer housing 30 can be suppressed.

[0050] (1-2) In the embodiment, the wire cover 40 has a first wall portion (side wall 42) and a protrusion 43 protruding from the first wall portion in a second direction (left-right direction) perpendicular to the first direction, and the outer housing 30 has a second wall portion (cover retaining wall 32) having a portion facing the first wall portion in the second direction, and a protrusion receiving portion 33 recessed from the second wall portion in the second direction, and the protrusion receiving portion 33 extends in a third direction (front-rear direction) perpendicular to the first and second directions to receive the protrusion 43.

[0051] According to this configuration, the wire cover 40 can be attached to the outer housing 30 by bringing the protrusion 43 and the protrusion receiving portion 33 into sliding contact with each other.

[0052] In the (1-3) embodiment, the contact portion 46 includes a first contact portion 46A and a second contact portion 46B that protrudes from the first contact portion 46A to the other side (downward) in the first direction.

[0053] With this configuration, the gap between the wire cover 40 and the inner housing 20 can be reduced, and rattling of the inner housing 20 can be suppressed.

[0054] (1-4) In the embodiment, the second abutment portion 46B extends in the third direction, and has an inclined portion 46B1 at one end (front end) in the third direction, and the protruding dimension of the inclined portion 46B1 from the first abutment portion 46A becomes larger toward the other side (rear) in the third direction.

[0055] According to this configuration, the gap between the wire cover 40 and the inner housing 20 can be smoothly filled by sliding the wire cover 40 to one side in the third direction.

[0056] (1-5) In the embodiment, the inner housing 20 has an abutment surface (upper surface 22A of the flange portion 22) that abuts against the abutment portion 46, and an opposing surface (outer peripheral surface 21C of the main body portion 21) that is arranged opposite the wire cover 40 in a direction perpendicular to the first direction (left-right direction), and the abutment surface and the opposing surface are arranged continuously.

[0057] With this configuration, the wire cover 40 can be positioned in a direction perpendicular to the first direction by the opposing surface.

[0058] (1-6) The connector 10 according to the embodiment includes a plurality of inner housings 20.

[0059] (Other embodiments) The above embodiment can be modified as follows: The above embodiment and the following modifications can be combined with each other to the extent that no technical contradiction occurs.

[0060] In the above embodiment, the connector 10 is a lever-type connector, but the connector does not have to be a lever-type connector.

[0061] In the above embodiment, the wire cover 40 has the protrusion 43, and the outer housing 30 has the protrusion receiving portion 33 that receives the protrusion 43. However, the protrusion may be provided on the outer housing, and the protrusion receiving portion may be provided on the wire cover.

[0062] In the above embodiment, when the wire cover 40 is attached to the outer housing 30, the protrusion 43 and the protrusion receiving portion 33 are configured to slide against each other. However, the wire cover and the outer housing do not need to have such a sliding contact structure as long as they are configured to be able to engage with each other. [Explanation of symbols]
