Summary of the Invention

Problem to be Solved by the Invention

[0004] In the above configuration, an electric cable is attached inside the main body of the connector housing, and the electric wire is fixed at a predetermined position by the cover of the connector housing, but there is no structure for regulating the position and posture of the electric wire in the connector housing. Therefore, for example, when assembling the main body of the connector housing and the cover, the electric wire may be displaced from its normal position, and the electric wire may be caught between the main body of the connector housing and the cover.

Means for Solving the Problem

[0005] The connector of this disclosure comprises a terminal, a housing having a wire lead-out portion and housing the terminal, and a wire connected to the terminal and led out in a first direction from the wire lead-out portion of the housing, wherein the housing comprises a housing body and a cover member assembled to the housing body, the wire lead-out portion comprises a receiving portion provided on the housing body that receives the wire from one side in a second direction perpendicular to the first direction, and a pressing portion provided on the cover member that holds the wire in place from the other side in the second direction, the receiving portion comprises a housing groove having an opening that opens to the other side in the second direction and housing the wire in a normal position, and a pair of tapered portions formed to widen as they extend from the opening toward the other side in the second direction. [Effects of the Invention]

[0006] According to this disclosure, it is possible to provide a connector that can suppress wire pinching during connector assembly. [Brief explanation of the drawing]

[Figure 5C]Figure 5C is a front view showing the state after the wire has been housed and the cover member has been assembled in the wire outlet section of one embodiment. [Figure 6] Figure 6 is a perspective cross-sectional view showing section AA of Figure 5. [Modes for carrying out the invention]

[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 terminal, a housing having a wire lead-out portion and housing the terminal, and a wire connected to the terminal and led out in a first direction from the wire lead-out portion of the housing, the housing comprising a housing body and a cover member assembled to the housing body, the wire lead-out portion comprising a receiving portion provided on the housing body for receiving the wire from one side in a second direction perpendicular to the first direction, and a pressing portion provided on the cover member for holding the wire in place from the other side in the second direction, the receiving portion comprising a housing groove having an opening that opens to the other side in the second direction and housing the wire in a normal position, and a pair of tapered portions formed to widen as they extend from the opening toward the other side in the second direction.

[0009] With this configuration, for example, when the cover member is assembled to the housing body, even if the wire is located in the middle of the tapered section, the retaining part can push the wire to the correct position, and the retaining part of the cover member and the receiving part of the housing body can prevent the wire from getting pinched. Furthermore, since each wire is securely housed in the correct position, vibrations transmitted to the terminals due to wire movement can be suppressed.

[0010] [2] In the connector described in [1] above, it is preferable that the electric wire is held in the second direction by the receiving portion and the pressing portion in the normal position.

[0011] With this configuration, the electric wire pulled out from the electric wire outlet in the first direction is held in a state where it is housed in its proper position, and movement of the electric wire in the first and second directions can be suppressed.

[0012] [3] In the connector described in [1] or [2] above, it is preferable that a projection is formed on the inner wall of the receiving groove in the receiving portion for clamping the electric wire in a third direction perpendicular to the first and second directions in the normal position.

[0013] With this configuration, the projection holds the electric wire in a third direction within the housing groove, thereby preventing the electric wire from moving in a third direction. Furthermore, when the cover component is removed from the housing body, the wires can be stored in the storage groove and held in their proper position, making it easier to further prevent the wires from getting caught.

[0014] [Details of the embodiments of this disclosure] Specific examples of the connectors of this disclosure will be described below with reference to the drawings. In each drawing, some parts of the configuration may be exaggerated or simplified for the sake of explanation. Also, the dimensional ratios of each part may differ in each drawing. In this specification, "orthogonal" and "parallel" include not only cases where they are strictly orthogonal or parallel, but also cases where they are approximately orthogonal or parallel within the range that produces the effects of this embodiment. As used in this description, "cylindrical" includes not only those in which a circumferential wall is formed continuously around the entire circumference, but also those formed by combining multiple parts to form a cylinder, and those having notches or other cutouts in part of the circumferential direction, such as C-shapes or U-shapes. The shape of "cylindrical" includes, but is not limited to, circular, elliptical, and polygons with pointed or rounded corners. In this specification, "opposing" means that faces or members are in a position 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 this specification, "opposing" includes not only cases where two members are separated from each other, but also cases where two members are in contact with each other. Furthermore, terms such as "first," "second," and "third" used herein are used merely to distinguish between subjects and do not rank them. The present invention is not limited to these examples, but is shown in the claims, and all modifications within the meaning and scope equivalent to the claims are intended.

[0015] <Embodiment> Embodiments of the present disclosure will be described with reference to FIG. 1 to FIG. 6. In the following description, the X-axis direction is defined as the left-right direction, the Y-axis direction as the up-down direction, and the Z-axis direction as the front-rear direction. Each drawing illustrates the X-axis direction, the Y-axis direction orthogonal to the X-axis direction, and the Z-axis direction orthogonal to both the X-axis direction and the Y-axis direction. In the description, the direction indicated by arrow X1, which is one direction along the X-axis direction in each drawing, is defined as the right direction, and the direction indicated by arrow X2, which is the other direction along the X-axis direction and opposite to the right direction X1, is defined as the left direction. The direction indicated by arrow Y1, which is one direction along the Y-axis direction in each drawing, is defined as the upward direction, and the direction indicated by arrow Y2, which is the other direction along the Y-axis direction and opposite to the upward direction Y1, is defined as the downward direction. The direction indicated by arrow Z1, which is one direction along the Z-axis direction in each drawing, is defined as the forward direction, and the direction indicated by arrow Z2, which is the other direction along the Z-axis direction and opposite to the forward direction Z1, is defined as the rearward direction. Here, the downward direction Y2 is the forward direction in the fitting direction of the connector 10 with respect to a mating connector (not shown). The forward direction Z1 is the forward direction in the wire drawing direction from which the electric wire 90 is drawn out. In the present embodiment, the front-rear direction is an example of a first direction, the up-down direction is an example of a second direction, and the left-right direction is an example of a third direction. Furthermore, for a plurality of identical members, reference numerals may be given to only some members, and reference numerals for other members may be omitted.

[0016] (Overall Configuration of Connector 10) As shown in FIG. 1, the connector 10 is configured to be fittable into a mating connector (not shown). The connector 10 is provided, for example, in a vehicle (not shown) such as a regular vehicle, a hybrid vehicle, or an electric vehicle. The connector 10 is a connector used for controlling a vehicle's seat belt pretensioner, airbag inflator, or the like, that is, a so-called squib connector.

[0017] (Configuration of Connector 10) As shown in FIG. 2, the connector 10 (see FIG. 1) includes a terminal 20, a housing 30, a slider 60, a spring 70, and a ferrite core 80. The connector 10 of the present embodiment includes two terminals 20.

[0018] (Configuration of terminal 20) As shown in Figure 2, the two terminals 20 are arranged side by side along the X-axis direction (left-right direction). Each terminal 20 has a wire connection portion 21 and a female terminal portion 22. The wire connection portion 21 extends along the Z-axis direction (front-back direction). The female terminal portion 22 extends along the Y-axis direction (up-down direction). Each terminal 20 is formed in an L-shape overall when viewed in the X-axis direction. Each terminal 20 is made of metal.

[0019] As shown in Figure 2, the wire connector 21 is connected to the wire 90. Here, the wire 90 is a coated wire having a conductive core wire and an insulating coating covering the outer circumference of the core wire. The wire connector 21 is connected to the end of the core wire of the wire 90. The wire connector 21 is connected to the core wire of the wire 90 by, for example, crimping or ultrasonic welding.

[0020] The female terminal portion 22 is connected to the rear end Z2 of the wire connection portion 21. The female terminal portion 22 extends in a direction perpendicular to the longitudinal direction of the wire connection portion 21. The female terminal portion 22 is formed in a cylindrical shape. The female terminal portion 22 has a connection portion 23 that connects to the wire connection portion 21 and a tongue portion 24.

[0021] The connection portion 23 is formed in the shape of a groove that opens to the right in direction X1. The connection portion 23 opens downward in direction Y2 and upward in direction Y1. Furthermore, the connection portion 23 extends downward in direction Y2 from the wire connection portion 21 and also extends upward in direction Y1 from the wire connection portion 21.

[0022] The tongue portion 24 is formed in a substantially cylindrical shape, extending downward from the lower Y2 end of the connecting portion 23 with a slit in the Y-axis direction. A mating terminal (not shown) is inserted into the tongue portion 24. The internal space of the tongue portion 24 is in communication with the internal space of the connecting portion 23.

[0023] (Housing 30 configuration) As shown in Figure 2, the housing 30 includes a housing body 31 and a cover member 50 formed to be attachable to the housing body 31. The housing body 31 is formed in a box shape with an opening upward Y1. The cover member 50 is attached to the housing body 31 so as to close the opening of the housing body 31. The housing body 31 and the cover member 50 are separate parts. Both the housing body 31 and the cover member 50 are made of resin.

[0024] The housing 30 is formed in a cylindrical shape that encloses the terminal 20, slider 60, and spring 70 by combining the housing body 31 and the cover member 50. In other words, the terminal 20, slider 60, and spring 70 are housed in the internal space of the housing 30 formed by the housing body 31 and the cover member 50.

[0025] As shown in Figures 2 and 3, the housing body 31 has a base portion 32 and peripheral walls 33, 34, 35, and 36 projecting upward Y1 from the base portion 32. The housing body 31 has a terminal housing portion 37 for housing the terminal 20 and a ferrite housing portion 38 for housing the ferrite core 80. The housing body 31 has a mounting portion 40 to which the slider 60 is attached and a spring housing portion 45 for housing the spring 70. As shown in Figure 3, the housing body 31 has two spring housing portions 45. Note that in Figure 3, the cover member 50 is omitted from the drawing for simplification.

[0026] As shown in Figure 2, the base portion 32 is formed in a flat plate shape. The peripheral wall 33 is provided at the rear end Z2 of the base portion 32. The peripheral wall 34 is provided at the front end Z1 of the base portion 32. The peripheral walls 33 and 34 extend along the X-axis direction (left-right direction). The peripheral wall 35 is provided at the right end X1 of the base portion 32. The peripheral wall 36 is provided at the left end X2 of the base portion 32. The peripheral walls 35 and 36 extend along the Z-axis direction (front-back direction).

[0027] A slider 60 is mounted on the mounting portion 40 along the downward direction Y2. The mounting portion 40 holds the slider 60 so that it can move along the Y-axis direction (vertical direction) within the internal space of the housing 30. The mounting portion 40 has a guide groove 41 provided on the outer circumferential surface of the terminal housing portion 37 and notches 43 provided on the peripheral walls 35, 36.

[0028] As shown in Figures 1 and 2, the housing body 31 has a fitting cylinder portion 46 that fits into the mating fitting cylinder portion (not shown) of the mating housing (not shown). The fitting cylinder portion 46 fits inside the mating fitting cylinder portion (not shown). As shown in Figure 2, the fitting cylinder portion 46 protrudes downward Y2 from the base portion 32.

[0029] As shown in Figure 3, the housing body 31 has engaging portions 47 provided on the peripheral walls 33, 35, and 36. The engaging portions 47 are engaging projections that protrude outward from the outer surfaces of the peripheral walls 33, 35, and 36. One engaging portion 47 is provided on peripheral wall 33. Two engaging portions 47 are provided on each of the peripheral walls 35 and 36.

[0030] (Configuration of cover member 50) As shown in Figure 1, the cover member 50 is attached to the housing body 31. The cover member 50 is formed to be detachably attached to the housing body 31. The cover member 50 has a cover body portion 51, an engaging portion 52 protruding downward Y2 from the cover body portion 51, and a peripheral wall 58 protruding downward Y2 from the cover body portion 51. In this embodiment, the cover member 50 has three engaging portions 52 corresponding to the engaged portion 47 of the housing body 31.

[0031] As shown in Figures 1 and 4, the cover body portion 51 is formed in a flat plate shape. The cover body portion 51 is formed to close the opening in the upward direction Y1 of the housing body 31. Each engaging portion 52 protrudes from the cover body portion 51 toward the housing body 31. Each engaging portion 52 is an elastic piece formed to be elastically deformable. Each engaging portion 52 is formed to protrude downward in the downward direction Y2 from the periphery of the cover body portion 51. One engaging portion 52 is formed on each long side of the periphery of the cover body portion 51, and one is formed on one of the short sides. Each engaging portion 52 has an engaging hole 53 capable of accommodating the engaged portion 47. The engaged portion 47 and the engaging portion 52 engage with each other by the elastic deformation of the elastic piece of the engaging portion 52. When the engaged portion 47 fits into the engaging hole 53 and engages with the engaging portion 52, the housing body 31 and the cover member 50 are maintained in a joined state.

[0032] (Configuration of Slider 60) As shown in Figures 2 and 3, the slider 60 has a slider body 61, a spring housing 63, a fitting guarantee portion 68, and a guide projection 69. The slider 60 is a single component in which the slider body 61, spring housing 63, fitting guarantee portion 68, and guide projection 69 are integrally formed. The slider 60 is made of resin.

[0033] As shown in Figure 3, the slider 60 is housed inside the housing 30. The slider 60 is held by the housing body 31 so as to be movable between a first position and a second position along the Y-axis direction (vertical direction). The first position is the position in which the slider body 61 is engaged with the base 32 of the housing body 31 in the Y-axis direction (vertical direction). The second position is the position in which the slider 60 is pressed upward Y1 by a mating housing (not shown).

[0034] When housing 30 and mating housing (not shown) are mated, the slider 60 is pressed upward in Y1 by the mating housing (not shown). As a result, the slider 60 moves parallel to the Y-axis (vertical direction) from the first position to the second position, while compressing the spring 70 in the Y-axis direction (vertical direction) against the biasing force of the spring 70. When the slider 60 is in the second position and is further pressed by the mating housing (not shown), the mating guarantee portion 68 elastically deforms to widen its opening, and the mating guarantee portion (not shown) enters the interior of the mating guarantee portion 68. This allows the slider 60 to move downward in Y2. When connector 10 and mating connector (not shown) are properly mated, the slider 60, which is in the second position, is biased toward the first position by the spring 70, and the slider 60 moves parallel to the Y-axis (vertical direction) from the second position to the first position.

[0035] As shown in Figures 2 and 3, the spring housing 63 is formed to accommodate a portion of the spring 70. The spring housing 63 has a U-shaped planar shape when viewed from below in Y2. The internal space of the spring housing 63 is formed by a space enclosed by a bottom surface (not shown), walls 65 and 66, and the peripheral wall 33 of the housing body 31. The wall 66 has, for example, a guide portion 67. The guide portion 67 is formed as an inclined surface (not shown) that slopes downward in Y2 as it approaches the internal space of the spring housing 63 from the protruding tip surface of the wall 66 (i.e., the end surface in the upward direction Y1) when viewed from the rear in the Y-axis direction. The guide portion 67 has the function of guiding the spring 70 into the internal space of the spring housing 63.

[0036] (Spring 70 configuration) As shown in Figure 2, the spring 70 is made of wire. The spring 70 is made of metal. The spring 70 has a pair of arms 71 and a connecting portion 75 that connects the pair of arms 71. The spring 70 has a pair of folded portions 76 provided at each end of the pair of arms 71 and a pair of extension portions 77 provided at the tip of each of the folded portions 76. The spring 70 is a single component in which the arms 71, the connecting portion 75, the folded portions 76, and the extension portions 77 are continuously and integrally formed.

[0037] The connecting portion 75 connects the rearward ends Z2 of a pair of arms 71. The connecting portion 75 extends along the X-axis direction (left-right direction). The connecting portion 75 is housed in the spring housing portion 63 of the slider 60. The connecting portion 75 is in line contact with the bottom surface of the spring housing portion 63 (see Figure 3).

[0038] A pair of folded portions 76 are provided so as to face each other in the X-axis direction (left-right direction). Each folded portion 76 is formed to fold back from the front end Z1 of each arm 71 toward the rear end Z2 of each arm 71. Each folded portion 76 is formed to fold back in a direction away from the base 32 of the housing body 31 (here, upward Y1). Each folded portion 76 is folded back in a U-shape from the front end Z1 of each arm 71. Each folded portion 76 is provided so as to be able to contact the inner surface of the cover member 50.

[0039] Each extension 77 extends from the tip of each folded portion 76 (in this case, the end in the rearward direction Z2) toward the other arm 71. Each extension 77 is provided so as to be able to contact the inner surface of the cover member 50.

[0040] (Ferrite core 80 configuration) The ferrite core 80 is attached to the outer circumference of the electric wire 90. The ferrite core 80 is formed to surround the outer circumference of the electric wire 90. The electric wire 90 is formed to pass through the ferrite core 80 in the Z-axis direction (front-to-back direction). The ferrite core 80 is housed in the ferrite housing portion 38 of the housing body 31.

[0041] (Wire outlet 30A of housing 30) As described above, the housing 30 is maintained in a state where the housing body 31 and the cover member 50 are joined together by the engagement of the engaged portion 47 and the engaging portion 52. In the housing 30, a wire outlet portion 30A is provided at the front end portion where the engagement structure between the engaged portion 47 and the engaging portion 52 is not provided. The electric wire 90 is pulled out from the electric wire outlet portion 30A in the forward direction Z1. With the electric wire 90 pulled out, the peripheral wall 58 of the cover member 50 and the peripheral wall 34 of the housing body 31 face each other in the vertical direction. The electric wire outlet portion 30A is composed of a pair of receiving portions 39 of the housing body 31, which will be described later, and a pair of pressing portions 57 of the cover member 50, which will be described later.

[0042] As shown in Figure 1, the pair of retaining portions 57 of the cover member 50 are formed on the peripheral wall 58. As shown in Figures 4 and 5(C), the peripheral wall 58 has an opposing surface 59 that faces the housing body 31 during assembly. The pair of retaining portions 57 are formed in the left-right central part of the peripheral wall 58. In other words, the retaining portions 57 are the parts of the peripheral wall 58 that protrude downward in the direction Y2. The retaining portions 57 have a tapered shape, with their left-right dimensions decreasing as they move downward in the direction Y2. The lower end of the retaining portion 57 is a plane that extends in the left-right direction. This plane constitutes part of the opposing surface 59. As shown in Figure 5(C), the pair of retaining portions 57 are configured to fit from above onto the pair of receiving portions 39 of the housing body 31.

[0043] As shown in Figures 1 and 5(A), a pair of receiving portions 39 of the housing body 31 are formed in the peripheral wall 34. The receiving portions 39 are the parts that receive the electric wire 90 from the downward direction Y2. The pair of receiving portions 39 are formed in the left-right central part of the peripheral wall 34. In other words, the receiving portions 39 are the parts of the peripheral wall 34 that are recessed downward in the Y2 direction. A housing groove 312 is formed at the lower end of the receiving portion 39. The housing groove 312 is composed of a pair of wall surfaces extending vertically in an XY plan view and a plane extending horizontally between the pair of wall surfaces. A single electric wire 90 is housed in the housing groove 312 from above. The housing groove 312 has an opening 310 that opens upward in the Y1 direction. A pair of tapered portions 313 are formed in the receiving portion 39 at a position that extends upward in the Y1 direction from the opening 310. The pair of tapered sections 313 are shaped such that the distance between them in the left-right direction increases as they move upward in the direction Y1. Therefore, the receiving section 39 has an opening 310 that opens upward in the direction Y1, a housing groove 312 into which the electric wire 90 is housed in a regular position (described later), and a pair of tapered sections 313 that are formed to widen as they move upward in the direction Y1 from the opening 310. As shown in Figures 1 and 5(C), the peripheral wall 34 of the housing body 31 has an opposing surface 34A that faces the opposing surface 59 of the cover member 50 when assembled. The opening 310, the housing groove 312, and the tapered sections 313 constitute a part of the opposing surface 34A. The tapered sections 313 do not have to be straight; they may be curved.

[0044] Figure 5(A) is an XY plan view front view showing the state before the cover member 50 is assembled and before the electric wire 90 is inserted. The normal position of the electric wire 90 is when the entire or a part of the electric wire 90 is housed in the housing groove 312 of the receiving portion 39 without any part of the electric wire 90 protruding.

[0045] Figure 5(B) is a front view in the XY plane showing the state before the cover member 50 is assembled and the two electric wires 90 are housed in their respective housing grooves 312. The two electric wires 90 are housed in their respective housing grooves 312 via a pair of tapered sections 313 and openings 310. The tapered sections 313 guide the electric wires 90 into the housing grooves 312 located below them in the direction Y2. In other words, the tapered sections 313 have an electric wire guiding function. By housing each electric wire 90 in its respective housing groove 312, it is held in its correct position, improving work efficiency, such as making it easier to assemble the cover member 50.

[0046] Figure 5(C) is an XY plan view front view showing the state in which the cover member 50 is assembled and the electric wire 90 is held in the correct position. In the electric wire outlet section 30A, when the retaining portion 57 and the receiving portion 39 face each other with the electric wire 90 held in the correct position, the retaining portion 57 and the receiving portion 39 are in close contact without any gaps, and the end faces of the retaining portion 57 and the receiving portion 39 are all facing each other. The housing groove 312 of the receiving portion 39 of the electric wire outlet section 30A is located near the center of the front surface of the connector 10. By fitting the electric wire 90 into the housing groove 312 and housing it in the correct position, the cover member 50 is assembled, which suppresses or reduces pinching of the electric wire 90. By preventing pinching, damage to the electric wire 90 can be prevented. As shown in Figures 5(B) and 5(C), when each wire 90 is housed or fitted into the housing groove 312, the shape of the wire 90 is shown to be deformed to match the shape of the housing groove 312. However, the wire 90 may be housed or fitted into the housing groove 312 without any deformation of its external shape.

[0047] For example, when the cover member 50 is assembled to the housing body 31, even if the electric wire 90 is located in the middle of the tapered portion 313, the retaining portion 57 can push the electric wire 90 to the correct position, and the retaining portion 57 of the cover member 50 and the receiving portion 39 of the housing body 31 can prevent the electric wire 90 from getting caught.

[0048] Furthermore, for example, if the cover member 50 opens, the tapered portion 313 has a guide function, so the electric wire 90 is reliably guided into the correct position and housed. When reassembling the cover member 50, the retaining portion 57 and the receiving portion 39 prevent the electric wire 90 from getting caught.

[0049] Therefore, when the electric wire 90 is housed between the retaining portion 57 and the receiving portion 39, the electric wire 90 pulled out from the electric wire exit portion 30A in the forward direction Z1 is held in its proper position, and movement of the electric wire in the Z-axis direction (forward and backward direction) and the Y-axis direction (up and down direction) can be suppressed. Furthermore, since each electric wire 90 is securely housed in its proper position, vibration of the electric wire 90 that would otherwise be transmitted to the terminal 20 can be suppressed.

[0050] (Method of assembling connector 10) Next, we will explain how to assemble connector 10. As shown in Figures 2 and 3, first, the slider 60 is attached to the mounting portion 40 of the housing body 31. More specifically, with the guide projection 69 fitted into the guide groove 41 and the wall portion 65 of the internal space of the spring housing portion 63 positioned in the notch 43, the slider 60 is slid downward along Y2 to the first position. At this time, the slider 60 slides downward along Y2 with the guide projection 69 guided by the guide groove 41.

[0051] Next, the terminal 20, the electric wire 90 connected to the terminal 20, and the ferrite core 80 attached to the outer circumference of the electric wire 90 are inserted into the terminal housing portion 37 and the ferrite housing portion 38 of the housing body 31 along the downward direction Y2.

[0052] Next, the spring 70 is attached to the housing body 31 and the slider 60. Specifically, the spring 70 is attached to the housing body 31 such that the ends of each arm 71 of the spring 70 in the forward direction Z1 are housed in each spring housing portion 45 of the housing body 31. At this time, the connecting portion 75 of the spring 70 may not be housed in the spring housing portion 63 of the slider 60. For example, the connecting portion 75 may be resting on the tip surface of the wall portion 66 of the internal space of the spring housing portion 63 or on the guide portion 67 which has the function of guiding the spring 70 into the internal space of the spring housing portion 63.

[0053] Next, as shown in Figures 1 and 3, a cover member 50 (see Figure 4) is attached to the housing body 31. This cover member 50 presses the spring 70 downward in direction Y2. As a result, the connecting portion 75 of the spring 70 and the rearward end Z2 of each arm 71 are guided along the guide portion 67 into the internal space of the spring housing portion 63. In this way, the spring 70 can be suitably housed in the spring housing portion 63 of the slider 60.

[0054] At this time, as shown in Figure 5(C), the electric wire 90 is housed in the housing groove 312 of the receiving portion 39 of the electric wire lead-out portion 30A in a state of being in the correct position. As shown in Figure 6, in the receiving portion 39, the housing groove 312 of the housing body 31 has an inner wall 312A having a constant thickness in the Z-axis direction (front-to-back direction). The inner wall 312A has projections 314 that protrude in the X-axis direction (left-to-right direction). The projections 314 have a rib shape that extends in the vertical direction. The projections 314 grip the peripheral edge of the electric wire 90, which is held in the correct position by being housed in the housing groove 312. In this embodiment, there are four projections 314 for one electric wire 90 or one housing groove 312. For example, there may be one or more projections 314, as long as the electric wire 90 is held in the correct position in the housing groove 312.

[0055] With this configuration, the projection 314 holds the electric wire 90 in the housing groove 312 in the X-axis direction (left-right direction), thereby suppressing movement of the electric wire 90 in the X-axis direction (left-right direction). Furthermore, for example, when it is necessary to remove the cover member 50 from the housing body 31 and reassemble the cover during assembly work, the electric wire 90 can be housed in the housing groove 312 and held in the correct position, making it easier to further suppress pinching of the electric wire 90. In addition, since each electric wire 90 is securely housed in the correct position, it is possible to suppress vibrations transmitted to the terminal 20 due to the electric wire 90 shaking.

[0056] By following the above steps, the connector 10 can be assembled.

[0057] (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.

[0058] (1) In the above embodiment, the connector 10 was provided with two identical wires 90, but this is just an example, and the connector may be provided with multiple wires of one type, or with multiple wires of two or more types, as long as it does not impair the purpose of the present disclosure.

[0059] (2) In the above embodiment, a pair of receiving portions 39 were provided, but this is just an example, and it is sufficient to provide at least one, as long as it does not impair the purpose of this disclosure.

[0060] (3) In the above embodiment, a pair of retaining portions 57 were provided, but this is just an example, and it is sufficient to provide at least one, as long as it does not impair the purpose of this disclosure.

[0061] (4) In the above embodiment, when the wire lead-out portion 30A is held in the correct position and the retaining portion 57 and the receiving portion 39 face each other, the respective opposing surfaces 34A and 59 of the retaining portion 57 and the receiving portion 39 are all facing each other. However, this is just one example, and as long as the purpose of this disclosure is not impaired, the respective opposing surfaces 34A and 59 of the retaining portion 57 and the receiving portion 39 may be partially facing each other.

[0062] (5) In the above embodiment, the position of the receiving groove 312 of the receiving portion 39 of the wire lead-out portion 30A is located at the center in the left-right direction of the peripheral wall 34 in the XY plan view of the connector, but this is just an example, and the position of the receiving groove 312 of the receiving portion 39 is not limited as long as it does not impair the purpose of this disclosure.

[0063] (6) In the above embodiment, the shape of the projection 314 of the receiving groove 312 is exemplified as having a rib shape extending in the vertical direction, but this is just one example, and other shapes are also acceptable as long as they do not impair the purpose of this disclosure.
