[0008] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. [1] The connector of the present disclosure comprises a plurality of terminals, a housing housing the plurality of terminals, a plurality of wires connected to the plurality of terminals and drawn out from one end face of the housing in a first direction, and a wire cover housing the plurality of wires, the wire cover being attached to the housing and comprising a first portion formed to narrow as it moves away from the housing in a first direction, and a second portion extending from the first portion to one side in the first direction, the first portion comprising a peripheral wall disposed around the plurality of wires, an inner rib extending from the inner surface of the peripheral wall and partitioning the internal space of the peripheral wall in a second direction perpendicular to the first direction, and an outer rib extending from the inner surface of the peripheral wall and disposed outside the plurality of wires in the second direction, the outer rib comprising an inclined portion that is located inward of the first portion in the second direction as it moves toward one side in the first direction.

[0009] With this configuration, the inner ribs separate multiple wires, preventing them from contacting each other and wearing down. In addition, the inclined portion of the outer ribs positions the wires arranged on the outside in the second direction, preventing them from bending excessively.

[0010] [2] In the above [1], it is preferable that the minimum distance between the inner rib and the outer rib is set to be slightly larger than the diameter of the electric wire arranged on the outside in the second direction.

[0011] With this configuration, the inner and outer ribs make it easier to position the wires that are positioned on the outside in the second direction.

[0012] [3] In the above [1] or [2], the peripheral wall preferably includes a first wall portion and a second wall portion that extends obliquely with respect to the first wall portion, and the outer rib is preferably connected to a boundary portion between the first wall portion and the second wall portion.

[0013] According to such a configuration, the strength of the peripheral wall can be increased by the outer rib.

[0014] [4] Any one of the connectors according to the above [1] to [3] further includes a sealing member that seals between each of the plurality of electric wires and the housing, and the outer rib preferably includes a pressing portion that presses the sealing member from one side in the first direction.

[0015] According to such a configuration, the outer rib can be provided with a function of pressing the sealing member, so that a member for pressing the sealing member does not need to be provided separately.

[0016] [5] In any one of the above [1] to [4], the plurality of electric wires include a first electric wire and a second electric wire thinner than the first electric wire, and the inner rib is preferably disposed between two of the first electric wires in the second direction.

[0017] According to such a configuration, the inner rib can suppress the first electric wires from contacting and wearing each other.

[0018] [6] Any one of the connectors according to the above [1] to [5] is preferably attached to the second portion and further includes a bundling member that bundles the plurality of electric wires housed in the second portion.

[0019] According to such a configuration, the plurality of electric wires can be bundled by the bundling member.

[0020] [Details of Embodiments of the Present Disclosure] Embodiments of the present disclosure are described below. This disclosure is not limited to these examples, but is indicated by the claims, and all modifications within the meaning and scope of the claims are intended to be included. In the drawings, some parts of the configuration may be exaggerated or simplified for illustrative purposes. Also, the dimensional ratios of the parts may differ in the drawings. In this specification, “orthogonal” includes not only strictly orthogonal but also approximately orthogonal to the extent that the function and effect of the present embodiment is achieved.

[0021] <Embodiment> Embodiments of this disclosure will be described with reference to Figures 1 to 9. In the following description, the direction indicated by arrow Z will be described as upward, the direction indicated by arrow X will be described as forward, and the direction indicated by arrow Y will be described as left. In this embodiment, the front-rear direction is an example of a first direction, and the left-right direction (width direction) is an example of a second direction. Note that for multiple identical members, reference numerals may be assigned to only some of the members, while the reference numerals for other members may be omitted.

[0022] (Connector 10, multiple terminals 20, multiple wires 30) As shown in Figure 1, the connector 10 of this embodiment comprises a plurality of terminals 20, a plurality of wires 30, a housing 40, and a wire cover 50. The plurality of terminals 20 include a first terminal 21 and a second terminal 22 which is smaller than the first terminal 21. The plurality of wires 30 include a first wire 31 and a second wire 32 which is thinner than the first wire 31. The first wire 31 is, for example, a power wire, which is a so-called thick wire. The second wire 32 is, for example, a signal wire.

[0023] The first terminal 21 is integrally formed by bending a conductive metal plate and comprises a main body portion 21A and a barrel portion 21B. The main body portion 21A is rectangular in shape, and a mating male tab (not shown) is inserted into the interior for connection. The barrel portion 21B is crimped to the first rubber stopper S1 fitted to the front end of the first electric wire 31 or to the first electric wire 31. The second terminal 22 also comprises a main body portion 22A and a barrel portion 22B, similar to the first terminal 21. The barrel portion 22B of the second terminal 22 is crimped to the second rubber stopper S2 fitted to the front end of the second electric wire 32 or to the second electric wire 32.

[0024] (Housing 40) The housing 40 is made of an insulating synthetic resin. As shown in Figure 7, the housing 40 has a rectangular block-shaped housing body 41 that is long in the width direction (left-right direction), and a mating cylinder portion 42 that surrounds the housing body 41. The hood portion (not shown) of the mating connector that is mated to the connector 10 enters between the housing body 41 and the mating cylinder portion 42. A seal ring 43 is fitted to the outer circumferential surface of the housing body 41. When the connector 10 and the mating connector are mated, the seal ring 43 is elastically compressed between the housing body 41 and the hood portion. This ensures that the mating surfaces of the connector 10 and the mating connector are sealed liquid-tight. The housing 40 is provided with engaging projections 42A that extend rearward from both sides of the rear end of the mating cylinder portion 42.

[0025] Furthermore, multiple terminal housing sections 44 are formed inside the housing body 41, aligned in the width direction. Each terminal housing section 44 consists of a relatively large first terminal housing section 44A located at both ends in the width direction of the housing body 41, and a relatively small second terminal housing section 44B located in the center in the width direction of the housing body 41. The first terminal housing section 44A is designed to accommodate the first terminal 21 and the first rubber stopper S1 by inserting them from the rear. The second terminal housing section 44B is designed to accommodate the second terminal 22 and the second rubber stopper S2 by inserting them from the rear.

[0026] The rear surface of the housing body 41 (an example of one end surface in the first direction) is the surface from which multiple electric wires 30 connected to multiple terminals 20 are drawn out. On the rear surface of the housing body 41, a first cylindrical portion 45A for housing a first rubber stopper S1 is formed projecting rearward at a position corresponding to the first terminal housing portion 44A. On the rear surface of the housing body 41, a second cylindrical portion 45B for housing a second rubber stopper S2 is formed projecting rearward at a position corresponding to the second terminal housing portion 44B. Each rubber stopper S1 and S2 elastically adheres to the outer circumferential surface of each electric wire 31 and 32 and the inner circumferential surface of each terminal housing portion 44A and 44B, respectively. This serves to create a liquid-tight seal around the electric wires 30 and inside the housing body 41.

[0027] Furthermore, as shown in Figures 4 and 5, a pair of locking parts 46 are formed projecting upward in the width direction near the rear end of the upper surface of the housing 40. Also, a pair of locking parts 46 are formed projecting downward in the width direction near the rear end of the lower surface of the housing 40.

[0028] As shown in Figure 1, the connector 10 is a lever-type connector and includes a lever 47 that assists in the mating operation between the connector 10 and the mating connector. As shown in Figure 7, the housing 40 includes shaft portions 48 that protrude outward from both sides of the housing 40. The shaft portions 48 rotatably support the lever 47.

[0029] (Wire cover 50) The wire cover 50 is made of an insulating synthetic resin. As shown in Figures 2 and 3, the wire cover 50 comprises a first part 51 that extends toward the rear in a manner that gradually narrows in width, and a second part 52 that extends toward the rear from the rear end of the first part 51. The second part 52 is connected to the rear end of the first part 51 at the center of the wire cover 50 in the width direction.

[0030] (Part 1 51) As shown in Figure 2, the first part 51 comprises a periphery wall 53 and inner ribs 54 and outer ribs 55 that project inward from the inner surface of the periphery wall 53 into the first part 51. The periphery wall 53 comprises a bottom wall 56, a pair of side walls 57 extending upward from both widthwise edges of the bottom wall 56, and a top wall 58 extending inward in the widthwise direction from the upper ends of each of the pair of side walls 57. The width of the bottom wall 56 gradually narrows towards the rear from the rear side of the housing 40. Multiple electric wires 30 are housed in the internal space 59 partitioned by the bottom wall 56, the pair of side walls 57, and the pair of top walls 58. The pair of top walls 58 are arranged substantially parallel to the bottom wall 56 and face the bottom wall 56 across the internal space 59.

[0031] As shown in Figure 7, each side wall 57 comprises a first wall portion 57A extending in the front-rear direction and a second wall portion 57B extending diagonally rearward from the first wall portion 57A. The second wall portion 57B is inclined with respect to the first wall portion 57A, and as it extends rearward, it is inclined toward the widthwise center of the first portion 51. The first wall portion 57A is provided with an engagement recess 57A1 that is concave from its front end. The engagement recess 57A1 is designed to accommodate the engagement projection 42A of the housing 40.

[0032] The front portion of the first part 51 has a contact portion 60 that can abut against the rear surface of the housing 40. The contact portion 60 is roughly rectangular and extends in the front-rear direction. As shown in Figure 2, gate-shaped locking receiving portions 61 are formed at the front ends of the bottom wall 56 and the pair of top walls 58. As shown in Figures 4 and 5, each locking receiving portion 61 is designed to engage with each locking portion 46 of the housing 40. The wire cover 50 is attached to the housing 40 by the engagement of each locking receiving portion 61 with each locking portion 46.

[0033] (Inner rib 54) As shown in Figure 2, a pair of inner ribs 54 are provided near the center of the width direction of the bottom wall 56. The inner ribs 54 protrude upward from the bottom wall 56. The inner ribs 54 are flattened into a plate shape in the left-right direction. As shown in Figure 8, the height dimension (vertical dimension) of the inner ribs 54 is approximately half the height dimension of the side wall 57. As shown in Figure 7, the inner ribs 54 extend in the front-rear direction from a position immediately behind the contact portion 60 to a position near the rear end of the first portion 51. The inner ribs 54 divide the internal space 59 in the left-right direction.

[0034] (Outer rib 55) As shown in Figure 2, the outer ribs 55 project inward from each side wall 57 in the width direction toward the first section 51. The outer ribs 55 are flattened in the vertical direction and extend in the front-rear direction. As shown in Figure 7, the outer ribs 55 include a base section 55A and an inclined section 55B extending rearward from the base section 55A. The widthwise edge of the base section 55A extends in the front-rear direction along the first wall section 57A. The widthwise edge of the inclined section 55B is inclined so that it is located further inward toward the first section 51 in the width direction toward the rear.

[0035] The front end portion 55A1 of the base portion 55A is positioned behind the first cylindrical portion 45A of the housing 40. By extending this front end portion 55A1 to near the rear end of the first cylindrical portion 45A, a retaining portion may be provided. The retaining portion has the function of holding down the first rubber stopper S1 (an example of a sealing member) housed in the first cylindrical portion 45A from the rear.

[0036] In this embodiment, the outer rib 55 is formed to include the boundary portion between the first wall portion 57A and the second wall portion 57B. This increases the strength of the side wall 57.

[0037] The minimum value D1 of the distance between the inner rib 54 and the outer rib 55 is set to be slightly larger than the diameter of the first wire 31. More specifically, the distance between the inner rib 54 and the outer rib 55 is narrowest between the rear end of the inner rib 54 and the rear end of the outer rib 55. The distance (minimum value D1) between the rear end of the inner rib 54 and the rear end of the outer rib 55 is slightly larger than the diameter of the first wire 31.

[0038] (Part 2 52) As shown in Figure 3, the second part 52 has a roughly semi-circular cross-section and extends in a trough-like shape in the front-to-back direction. The inner and outer surfaces of the second part 52 are smoothly connected to the inner and outer surfaces of the first part 51 without any steps. The upper ends (both ends in the width direction) of the second part 52 are positioned lower than the top wall 58 of the first part 51 and are connected to the top wall 58 in a stepped manner.

[0039] Next, an example of the assembly process for connector 10 will be described. First, the terminals 21 and 22, to which the electric wires 31 and 32 are crimped, are inserted into the terminal housings 44A and 44B from the rear of the housing 40. Once the terminals 21 and 22 are inserted into their respective positions in the terminal housings 44A and 44B, the rubber stoppers S1 and S2 come into close contact with the inner surfaces of the terminal housings 44A and 44B.

[0040] Next, a wire cover 50 is attached to the rear surface of the housing 40. Multiple wires 30 are housed in the internal space 59 of the first part 51 through an opening between a pair of top walls 58, while the rear half of the housing 40 is housed inside the contact part 60. The engaging projection 42A of the housing 40 is housed in the engaging recess 57A1 of the first part 51. Each locking part 46 of the housing 40 is locked in place by fitting into each locking receiving part 61 located at the corresponding position on the contact part 60.

[0041] As shown in Figure 7, the second wire 32, which is positioned closer to the center in the width direction among the multiple wires 30, is housed between a pair of inner ribs 54. The first wire 31, which is positioned on the outer side in the width direction among the multiple wires 30, is housed between the inner rib 54 and the outer rib 55. Multiple wires 30 are placed together on the second section 52.

[0042] When multiple electric wires 30 are housed within the electric wire cover 50, the inner ribs 54 separate the first electric wire 31 from other first electric wires 31. Therefore, wear on the first electric wires 31 due to friction with each other in a vibrating environment is suppressed. Although the second electric wires 32 are arranged inside a pair of inner ribs 54, they have a smaller diameter and are lighter than the first electric wires 31, and their degree of bending is also less than that of the first electric wires 31. Therefore, wear on the second electric wires 32 due to contact with each other is not as problematic as that on the first electric wires 31.

[0043] The outer rib 55 restricts the bending posture of the first electric wire 31 in the first section 51. Specifically, since the outer rib 55 protrudes inward in the width direction compared to the side wall 57, the outer rib 55 interferes with the first electric wire 31, restricting the first electric wire 31 from bending outward in the width direction. The inclined portion 55B of the outer rib 55 interferes with the first electric wire 31, causing the first electric wire 31 to bend inward in the width direction. The inclination angle of the inclined portion 55B with respect to the first wall section 57A is smaller than that of the second wall section 57B. Therefore, it is easier to reduce the bending of the first electric wire 31 compared to the case where the outer rib 55 is not provided (details will be described later).

[0044] The distance (minimum value D1) between the rear end of the inner rib 54 and the rear end of the outer rib 55 is set to be slightly larger than the diameter of the first electric wire 31, making it easier to position the first electric wire 31 near the rear end of the first part 51.

[0045] (Binding member 70) As shown in Figure 6, the connector 10 may be equipped with a binding member 70 that is wrapped around the outside of the second part 52 and bundles multiple wires 30 together. This allows multiple wires 30 to be fixed in place. Specifically, the binding member 70 is a cable tie or tape. When multiple wires 30 are bundled together with the binding member 70, the second part 52 deforms into a roughly cylindrical shape to match the outer shape of the multiple wires 30. The first part 51 also deforms accordingly. As a result, compared to the case where the wires 30 are not bundled together with the binding member 70 (see Figure 8), as shown in Figure 9, the distance between the inner rib 54 and the outer rib 55 is narrowed, making it easier to fix the first wire 31.

[0046] <Comparative Example> Figure 10 shows a cross-sectional view of connector 110 according to the comparative example. Figure 10 shows a cross-section corresponding to Figure 7 of the embodiment. Connector 110 is configured similarly to connector 10 of the embodiment, except that it does not have inner ribs 54 and outer ribs 55. That is, the wire cover 150 according to the comparative example has a first part 151 that does not have inner ribs 54 and outer ribs 55. In Figure 10, the same reference numerals are used for the same components as in Embodiment 1.

[0047] In the connector 110, since there is no outer rib 55, the first wire 31 can bend until it contacts the second wall portion 57B. Therefore, as shown in Figure 10, the first wire 31 may bend significantly into a roughly S-shape. Also, since the connector 110 is not provided with an inner rib 54, the first wires 31 may rub against each other within the first portion 151 or the second portion 52 in a vibrating environment. In particular, as shown in Figure 10, the first wires 31 in a significantly bent position are more likely to come into contact near the rear end of the first portion 151 or in the second portion 52. Therefore, in the connector 110, which does not have an inner rib 54 or an outer rib 55, the first wires 31 are more susceptible to wear in a vibrating environment. This is also true when a binding member 70 is provided.

[0048] On the other hand, in the connector 10 of this embodiment, as described above, the inner ribs 54 separate the first wires 31 from each other, and the outer ribs 55 restrict excessive bending of the first wires 31, thereby suppressing wear of the first wires 31 in a vibrating environment.

[0049] (Effects of the embodiment) (1) The connector 10 according to the embodiment comprises a plurality of terminals 20, a housing 40 that houses the plurality of terminals 20, a plurality of electric wires 30 connected to the plurality of terminals 20 and drawn out from one end face (rear face) in the first direction (front-rear direction) of the housing 40, and an electric wire cover 50 that houses the plurality of electric wires 30, the electric wire cover 50 being attached to the housing 40 and having a first part 51 that is formed to become narrower as it moves away from the housing 40 in the first direction, and from the first part 51 in the first direction The first part 51 comprises a circumferential wall 53 arranged around a plurality of electric wires 30, an inner rib 54 extending from the inner surface of the circumferential wall 53 and partitioning the internal space 59 of the circumferential wall 53 in a second direction (left-right direction) perpendicular to the first direction, and an outer rib 55 extending from the inner surface of the circumferential wall 53 and arranged outside the plurality of electric wires 30 in the second direction, the outer rib 55 having an inclined portion 55B that is located inward of the first part 51 in the second direction as it moves toward one side in the first direction.

[0050] With this configuration, the inner rib 54 separates the multiple electric wires 30, preventing them from contacting each other and wearing down. In addition, the inclined portion 55B of the outer rib 55 positions the electric wire 30 (first electric wire 31) that is positioned on the outside in the second direction, preventing the electric wire 30 from bending excessively.

[0051] (2) In this embodiment, the minimum value D1 of the distance between the inner rib 54 and the outer rib 55 is set to be slightly larger than the diameter of the electric wire 30 arranged on the outside in the second direction.

[0052] With this configuration, the inner rib 54 and outer rib 55 make it easier to position the electric wire 30 which is arranged on the outside in the second direction.

[0053] (3) In this embodiment, the peripheral wall 53 comprises a first wall portion 57A and a second wall portion 57B that extends inclined with respect to the first wall portion 57A, and the outer rib 55 is connected to the boundary portion between the first wall portion 57A and the second wall portion 57B.

[0054] With this configuration, the outer ribs 55 can increase the strength of the peripheral wall 53.

[0055] (4) The connector 10 according to the embodiment further comprises a sealing member (first rubber stopper S1) that seals the space between each of the plurality of electric wires 30 and the housing 40, and the outer rib 55 preferably comprises a pressing portion (front end portion 55A1) that presses the sealing member from one side in the first direction.

[0056] With this configuration, the outer rib 55 can be given the function of holding down the sealing member, so it is not necessary to provide a separate member for holding down the sealing member.

[0057] (5) In this embodiment, the plurality of wires 30 include a first wire 31 and a second wire 32 which is thinner than the first wire 31, and the inner rib 54 is positioned between the two first wires 31 in the second direction.

[0058] With this configuration, the inner ribs 54 can suppress wear caused by contact between the first electric wires 31.

[0059] (6) The connector 10 according to the embodiment preferably further comprises a bundling member 70 attached to the second part 52 for bundling together a plurality of electric wires 30 housed within the second part 52.

[0060] With this configuration, multiple electric wires 30 can be bundled together using the bundling member 70.

[0061] (Other embodiments) The above embodiment can be implemented with the following modifications. The above embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0062] In the above embodiment, the connector 10 was equipped with a first wire 31 and a second wire 32, but the connector may be equipped with multiple wires of one type, or with multiple wires of three or more types.

[0063] In the above embodiment, one pair of inner ribs 54 and one pair of outer ribs 55 were provided, but it is sufficient to provide at least one inner rib and one outer rib.

[0064] In the above embodiment, the inner rib 54 was provided on the bottom wall 56 and the outer rib 55 was provided on the side wall 57, but the wall portion constituting the peripheral wall to which the inner rib and outer rib are provided may be changed as appropriate. For example, in the above embodiment, the outer rib 55 was a flattened plate shape in the vertical direction and extended from the side wall 57, but the outer rib may be a flattened plate shape in a direction perpendicular to the vertical direction and extend from the bottom wall.

[0065] In the above embodiment, the connector 10 was equipped with a lever 47, but the connector does not need to be equipped with a lever.
