[0004] By the way, in the above connector, further improvement in waterproof performance is desired. An object of the present disclosure is to provide a connector capable of improving waterproof performance.

Means for Solving the Problems

[0005] The connector of this disclosure includes a conductive terminal, a metal shield shell covering the terminal, and a cover member attached to the shield shell along a first direction so as to close an opening provided in the shield shell, wherein the cover member has a metal cover body having a first base portion that closes the opening, a frame-shaped insertion portion that protrudes from the first base portion toward the first direction and is inserted into the interior of the shield shell, and a first engaging portion, an annular sealing member attached to the outer circumference of the insertion portion and sealing the space between the insertion portion and the shield shell, and a synthetic resin retainer attached to the cover body and preventing the sealing member from coming off the insertion portion, wherein the retainer has a second engaging portion formed to engage with the first engaging portion. [Effects of the Invention]

[0006] The connector described herein has the effect of improving waterproofness. [Brief explanation of the drawing]

[Figure 8] Figure 8 is a cross-sectional view (cross-sectional view of line 8-8 in Figure 4) showing a connector of one embodiment. [Modes for carrying out the invention]

[0008] [Description of Embodiments in this Disclosure] First, embodiments of this disclosure will be listed and described. [1] The connector of the present disclosure comprises a conductive terminal, a metal shield shell covering the terminal, and a cover member attached to the shield shell along a first direction so as to close an opening provided in the shield shell, the cover member comprising a metal cover body having a first base portion that closes the opening, a frame-shaped insertion portion that protrudes from the first base portion toward the first direction and is inserted into the interior of the shield shell, and a first engaging portion, an annular sealing member attached to the outer circumference of the insertion portion and sealing the space between the insertion portion and the shield shell, and a synthetic resin retainer attached to the cover body and preventing the sealing member from coming off the insertion portion, the retainer comprising a second engaging portion formed to engage with the first engaging portion.

[0009] In this configuration, the cover member attached to the shield shell comprises a metal cover body having an insertion portion that is inserted into the inside of the shield shell, a sealing member attached to the outer circumference of the insertion portion, and a synthetic resin retainer that prevents the sealing member from coming off. Therefore, the retainer, which is a separate part from the cover body, can prevent the sealing member from coming off the insertion portion. Consequently, there is no need to provide a structure, such as a protrusion, at the tip of the insertion portion of the cover body to prevent the sealing member from coming off.

[0010] In this case, if a protrusion perpendicular to the insertion direction is provided at the tip of the insertion part, it is necessary to manufacture the cover body using a complex slide mold. In this case, the parting line of the slide mold is formed to extend along the axial direction of the insertion part, so burrs are formed on the outer surface of the insertion part, i.e., the sealing surface, along the parting line. Such burrs cause a decrease in the sealing performance of the sealing member, so processing to remove the burrs, such as cutting, is necessary. Furthermore, even if the burrs are removed by cutting, there is a risk of a minute step difference occurring between the cut surface and the rest of the outer surface of the insertion part. If such a minute step difference occurs on the sealing surface, the sealing performance of the sealing member will decrease.

[0011] In contrast, with the above configuration, there is no need to provide a protrusion at the tip of the insertion part, so the cover body can be manufactured without using a slide mold. As a result, no burrs are formed on the outer surface of the insertion part, i.e., the sealing surface, and there is no need to perform cutting to remove the burrs. Therefore, it is possible to effectively suppress the occurrence of minute steps on the sealing surface caused by cutting. As a result, the sealing performance of the sealing member can be improved compared to the case in which a protrusion is provided at the tip of the insertion part, and consequently the waterproof performance of the connector can be improved.

[0012] [2] In the above [1], the second engaging portion is an elastic piece that can be elastically deformed in a second direction perpendicular to the first direction, the cover body has a pair of protrusions provided so as to sandwich the first engaging portion in a third direction perpendicular to both the first and second directions, the retainer has a pair of holes provided so as to sandwich the second engaging portion in the third direction, each of the pair of protrusions protrudes toward the first direction from the end face of the insertion portion toward the first direction, the pair of protrusions are fitted into the pair of holes, and the inner surface of each of the pair of holes may be able to contact the protrusions toward the second direction.

[0013] According to this configuration, the second engaging portion engaged with the first engaging portion is formed to be elastically deformable in a second direction orthogonal to the first direction. Here, since the cover body is made of metal while the retainer is made of synthetic resin, the cover body and the retainer have different coefficients of thermal expansion from each other. Due to such a difference in the coefficient of thermal expansion, the retainer may shrink thermally more significantly than the cover body. At this time, if the retainer shrinks thermally significantly in the second direction, there is a risk that the engagement state between the first engaging portion and the second engaging portion may be unintentionally released.

[0014] In contrast, in the above configuration, a pair of protrusions are provided on the cover body so as to sandwich the first engaging portion, and a pair of holes into which the pair of protrusions are respectively fitted are provided on the retainer. Further, the inner surface of each hole is provided so as to be capable of contacting the metal protrusion in the second direction. By the contact between each of these holes and the protrusion, it is possible to suppress the retainer from thermally shrinking in the second direction in the vicinity of the first engaging portion and the second engaging portion. Therefore, it is possible to suppress the second engaging portion from thermally shrinking significantly in the second direction. Thereby, it is possible to preferably suppress the engagement state between the first engaging portion and the second engaging portion from being unintentionally released due to the thermal shrinkage of the retainer.

[0015] [3] In the above [1] or [2], the retainer has a second base portion and a fitting portion protruding from the second base portion in a first opposite direction which is the opposite direction of the first direction, the fitting portion has an outer surface along the inner surface of the insertion portion, and may be fitted inside the insertion portion.

[0016] According to this configuration, the fitting portion having an outer surface along the inner surface of the insertion portion is fitted inside the insertion portion. Therefore, while fitting the fitting portion inside the insertion portion, the retainer can be attached to the cover body. Accordingly, the retainer can be attached to the cover body while aligning by the fitting of the fitting portion to the insertion portion. As a result, the workability when attaching the retainer to the cover body can be improved.

[0017] [4] In [3] above, the retainer has one or more crushing ribs provided on the outer surface of the fitting portion. The crushing ribs extend along the first direction, and the crushing ribs may be press-fitted inside the insertion portion.

[0018] According to this configuration, in a state where the fitting portion is fitted inside the insertion portion, the crushing ribs are crushed by the inner surface of the insertion portion, so that the crushing ribs are crushed against the inner surface of the insertion portion. Thereby, rattling between the insertion portion and the fitting portion can be suppressed, and further, rattling between the cover body and the retainer can be suppressed.

[0019] [5] In [3] or [4] above, the first base portion has a first protruding portion protruding outward from the insertion portion, and the second base portion has a second protruding portion protruding outward from the fitting portion and facing the first protruding portion in the first direction. The seal member may be provided between the first protruding portion and the second protruding portion in the first direction.

[0020] According to this configuration, the seal member is provided between the first protruding portion of the first base portion of the cover body and the second protruding portion of the second base portion of the retainer. Thereby, the movement of the seal member in the first direction and the first opposite direction can be restricted by the second protruding portion and the first protruding portion. Therefore, it is possible to suitably suppress the seal member from detaching from the insertion portion.

[0021] [6] In any one of [3] to [5] above, the cover body has a first reinforcing rib formed so as to protrude from the end surface of the first base portion in the first direction toward the first direction, and the second base portion has a closing portion that closes the opening of the fitting portion in the first direction. The retainer may have a second reinforcing rib formed so as to protrude from the end surface of the closing portion in the first opposite direction toward the first opposite direction.

[0022] With this configuration, the rigidity of the cover body can be increased by providing the first reinforcing rib. Furthermore, the rigidity of the retainer can be increased by providing the second reinforcing rib.

[0023] [7] In the above [6], a gap may be provided between the end face of the first reinforcing rib in the first direction and the end face of the second reinforcing rib in the first opposite direction. With this configuration, when the retainer is attached to the cover body, the first reinforcing rib and the second reinforcing rib do not come into contact with each other. Therefore, it is possible to suppress the generation of abnormal noise caused by contact between the first reinforcing rib and the second reinforcing rib.

[0024] [8] In the above [6] or [7], the retainer has a fitting recess into which the first reinforcing rib is fitted, the fitting recess is formed to be recessed toward the first direction from the first opposite end face of the fitting portion, and the inner surface of the fitting recess may be in contact with the first reinforcing rib in a direction intersecting the first direction.

[0025] In this configuration, the first reinforcing rib is fitted into a fitting recess provided on the first opposite end face of the fitting portion. At this time, since the inner surface of the fitting recess can contact the first reinforcing rib in a direction intersecting the first direction, it is possible to suppress movement of the retainer in a direction intersecting the first direction.

[0026] [9] In any of the above [3] to [8], the sealing member has a positioning projection that protrudes toward the first direction from the end face of the sealing member in the first direction, the retainer has a positioning recess into which the positioning projection is fitted, the positioning recess is formed to cut out the outer circumferential surface of the second base, and the inner surface of the positioning recess may be able to contact the positioning projection in a second direction perpendicular to the first direction.

[0027] In this configuration, the positioning projection of the sealing member is fitted into the positioning recess provided in the retainer. At this time, since the positioning projection can contact the inner surface of the positioning recess in a second direction, it is possible to suppress the movement of the sealing member in the second direction.

[0040] (Configuration of cover member 60) The cover member 60 is attached to the shield shell 41 so as to close the opening 42 of the shield shell 41. The cover member 60 is provided to completely cover the opening 42. The cover member 60 is assembled to the shield shell 41 along the forward direction X1.

[0041] The cover member 60 includes a cover body 70, an annular sealing member 80 attached to the cover body 70, and a retainer 90 attached to the cover body 70 that prevents the sealing member 80 from coming off.

[0042] (Composition of the cover body 70) As shown in Figure 3, the cover body 70 has a first base portion 71, a frame-shaped insertion portion 72 formed on the end face of the first base portion 71 in the forward direction X1, and a first engagement portion 73. The cover body 70 also has a projection 74, a first reinforcing rib 75, and a fixing portion 76. The cover body 70 is a single component in which the first base portion 71, the insertion portion 72, the first engagement portion 73, the projection 74, the first reinforcing rib 75, and the fixing portion 76 are integrally formed. The cover body 70 is made of metal. For example, metal materials such as aluminum-based or iron-based materials can be used as the material for the cover body 70. The cover body 70 in this embodiment is an aluminum casting.

[0043] As shown in Figure 1, the first base portion 71 is formed in a flat plate shape. The planar shape of the first base portion 71, as viewed in the forward direction X1, is formed as a rounded rectangle. The planar shape of the first base portion 71 as viewed in the forward direction X1 is formed as a rounded rectangle having a long side extending along the second axis Y and a short side extending along the third axis Z. The first base portion 71 has thickness along the first axis X.

[0044] As shown in Figure 3, the first base portion 71 is provided to close the rearward opening X2 of the insertion portion 72. The first base portion 71 has a first projection 71A that extends outward from the outer surface of the insertion portion 72.

[0046] The insertion portion 72 is formed to protrude forward in the forward direction X1 from the end face of the first base portion 71 in the forward direction X1. The insertion portion 72 is formed in a rectangular frame shape as a whole. The planar shape of the insertion portion 72, when viewed in the rear direction X2, is formed as a rounded rectangle, with the second axis Y being longer than the third axis Z. The insertion portion 72 of this embodiment has two first long sides 72A extending along the second axis Y and two first short sides 72B extending along the third axis Z. A sealing member 80 is attached to the outer surface of the insertion portion 72. That is, the outer surface of the insertion portion 72 is the sealing surface of the inner circumference of the sealing member 80. The outer surface of the insertion portion 72 does not have any steps along the entire length of the first axis X. That is, no convex or concave parts are formed on the outer surface of the insertion portion 72. In other words, no convex part for preventing the sealing member 80 from coming off is formed at the tip of the insertion portion 72.

[0047] As shown in Figure 4, the insertion portion 72 is formed to be insertable into the internal space of the shield shell 41 through the opening 42. The outer surface of the insertion portion 72 is formed to correspond to the shape of the inner surface of the shield shell 41.

Each protrusion 74 is formed to project forward in the forward direction X1 from the end face of the insertion portion 72 in the forward direction X1. Each protrusion 74 is formed, for example, in the shape of a rectangular parallelepiped. Each protrusion 74 is provided on each first short side portion 72B of the insertion portion 72. Each protrusion 74 is provided in the vicinity of the first engaging portion 73. Two of the four protrusions 74 are provided in the vicinity of each of the two first engaging portions 73. That is, a pair of protrusions 74 is provided for each first engaging portion 73. The pair of protrusions 74 are provided so as to sandwich the first engaging portion 73 between them along the third axis Z. In other words, the pair of protrusions 74 are provided on both sides of the first engaging portion 73 along the third axis Z.

[0051] The first reinforcing rib 75 is provided in the internal space of the insertion portion 72. The first reinforcing rib 75 is formed to protrude forward in the forward direction X1 from the end face of the first base portion 71 in the forward direction X1. The amount of protrusion of the first reinforcing rib 75 from the first base portion 71 is smaller than the amount of protrusion of the insertion portion 72 from the first base portion 71. In this embodiment, the planar shape of the first reinforcing rib 75 when viewed in the rear direction X2 is formed in a grid or lattice shape. Specifically, the first reinforcing rib 75 in this embodiment has two first ribs 75A extending along the second axis Y and two second ribs 75B extending along the third axis Z. The two first ribs 75A are provided side by side along the third axis Z. Each first rib 75A extends from the inner surface of one first short side portion 72B of the insertion portion 72 to the inner surface of the other first short side portion 72B. Each first rib 75A is formed integrally with the first short side portion 72B. Each first rib 75A is formed to cross two second ribs 75B. The two second ribs 75B are arranged side by side along the second axis Y. Each second rib 75B extends from the inner surface of one first long side portion 72A of the insertion portion 72 to the inner surface of the other first long side portion 72A. Each second rib 75B is formed integrally with the first long side portion 72A. Each second rib 75B is formed to cross two first ribs 75A.

[0052] As shown in Figure 2, the cover body 70 of this embodiment has two fixing parts 76. Each fixing part 76 is formed to protrude outward from the outer peripheral surface of the first base part 71. Each fixing part 76 has a fixing hole 77 into which a screw B1 is inserted. Each fixing hole 77 is formed to penetrate the fixing part 76 along the first axis X. Each fixing hole 77 is provided to overlap with the screw hole 43 of the shield shell 41 in the forward direction X1. The cover body 70 is fixed to the shield shell 41 by the screws B1 inserted into the fixing holes 77 and the screw hole 43.

[0053] (Configuration of sealing member 80) As shown in Figure 3, the sealing member 80 is attached to the outer circumference of the insertion portion 72. The sealing member 80 is formed to surround the insertion portion 72 around its entire circumference. The sealing member 80 in this embodiment is formed in a rectangular annular shape. The sealing member 80 is formed in a shape that conforms to the outer surface of the insertion portion 72. The planar shape of the sealing member 80 as viewed in the forward direction X1 is a rounded rectangle having a long side extending along the second axis Y and a short side extending along the third axis Z. The sealing member 80 is formed to be elastically deformable. As shown in Figure 4, when the insertion portion 72 is inserted into the internal space of the shield shell 41, the sealing member 80 adheres tightly to the outer surface of the insertion portion 72 around its entire circumference and also adheres tightly to the inner surface of the shield shell 41 around its entire circumference. In this way, the sealing member 80 seals the space between the outer surface of the insertion portion 72 and the inner surface of the shield shell 41. The sealing member 80 is made of rubber, for example. For example, silicone rubber, acrylic rubber, ethylene propylene rubber, etc., can be used as the material for the sealing member 80.

[0054] As shown in Figure 3, the sealing member 80 has one or more (two in this embodiment) positioning protrusions 81. The two positioning protrusions 81 are spaced apart from each other in the circumferential direction of the sealing member 80. The two positioning protrusions 81 are provided, for example, on the long side portion of the sealing member 80. Each positioning protrusion 81 is formed to project forward from the end face of the sealing member 80 in the forward direction X1. The two positioning protrusions 81 are positioned to face each other along the third axis Z.

[0055] (Composition of Retainer 90) The retainer 90 is assembled along the rearward direction X2 to the cover body 70, which has a sealing member 80 attached to the outer circumference of the insertion portion 72.

[0056] As shown in Figure 5, the retainer 90 has a second base portion 91, a fitting portion 92 formed on the rear end face X2 of the second base portion 91, and a second engaging portion 93. The retainer 90 also has a hole portion 94 and a second reinforcing rib 95. The retainer 90 is a single component in which the second base portion 91, the fitting portion 92, the second engaging portion 93, the hole portion 94, and the second reinforcing rib 95 are integrally formed. The retainer 90 is made of synthetic resin. For example, synthetic resins such as polyolefin, polyamide, and ABS resin can be used as the material for the retainer 90.

[0057] As shown in Figure 3, the second base portion 91 is formed in a flat plate shape. The planar shape of the second base portion 91, as viewed in the rear direction X2, is formed as a rounded rectangle. The planar shape of the second base portion 91, as viewed in the rear direction X2, is formed as a rounded rectangle having a long side extending along the second axis Y and a short side extending along the third axis Z. The second base portion 91 has thickness along the first axis X.

[0058] As shown in Figure 5, the second base portion 91 has a second projection 91A that extends outward from the outer surface of the fitting portion 92, and a closing portion 91B that closes the opening of the fitting portion 92 in the forward direction X1. The second projection 91A is formed continuously around the entire circumference.

[0059] As shown in Figure 6, the rear end face X2 of the second projection 91A is formed to be able to contact the front end face X1 of the insertion portion 72. The second projection 91A is formed to protrude outward from the outer surface of the insertion portion 72. The second projection 91A is formed to face the seal member 80 along the first axis X. The second projection 91A is formed to be able to contact the seal member 80 along the first axis X and is formed to restrict the movement of the seal member 80 in the front direction X1. The second projection 91A functions as a retaining portion to prevent the seal member 80 from coming out of the cover body 70. Here, the seal member 80 is provided between the first projection 71A and the second projection 91A along the first axis X.

[0060] As shown in Figure 5, the fitting portion 92 is formed to protrude from the end face of the second base portion 91 in the rear direction X2 toward the rear direction X2. The fitting portion 92 is formed in a frame shape. In this embodiment, the fitting portion 92 is formed in a rectangular frame shape as a whole. The planar shape of the fitting portion 92, as viewed in the front direction X1, is formed as a rounded rectangle, with the second axis Y being longer than the third axis Z. The fitting portion 92 in this embodiment has two second long sides 92A extending along the second axis Y and two second short sides 92B extending along the third axis Z. Thus, the planar shape of the fitting portion 92 as viewed in the front direction X1 is formed to be the same as the planar shape of the insertion portion 72 (see Figure 3) as viewed in the rear direction X2. In other words, the outer surface of the fitting portion 92 is formed to be the same as the inner surface of the insertion portion 72.

[0061] As shown in Figure 6, the fitting portion 92 is fitted inside the insertion portion 72. The amount of protrusion of the fitting portion 92 from the second base portion 91 is smaller than the amount of protrusion of the insertion portion 72 from the first base portion 71. The tip surface of the fitting portion 92, that is, the end surface of the fitting portion 92 in the rear direction X2, is not in contact with the end surface of the first base portion 71 in the front direction X1. A guide surface 92C is provided at the tip of the fitting portion 92. The guide surface 92C is formed such that the fitting portion 92 becomes narrower as it approaches the tip surface of the fitting portion 92. The guide surface 92C is provided at the corner between the tip surface of the fitting portion 92 and the outer surface of the fitting portion 92. The guide surface 92C has the function of smoothly guiding the fitting portion 92 into the interior of the insertion portion 72 when the fitting portion 92 is inserted inside the insertion portion 72.

[0062] As shown in Figure 5, the retainer 90 of this embodiment has two second engaging portions 93. Each second engaging portion 93 is provided on each second short side portion 92B of the fitting portion 92. In other words, each second engaging portion 93 constitutes a part of each second short side portion 92B. Each second engaging portion 93 is provided, for example, in the center of each second short side portion 92B along the third axis Z. The two second engaging portions 93 are provided so as to face each other along the second axis Y. Each second engaging portion 93 is an elastically deformable elastic piece that protrudes in the rearward direction X2 from the end face of the second base portion 91 in the rearward direction X2. Each second engaging portion 93 is, for example, an engaging frame portion. Each second engaging portion 93 is formed, for example, in a rectangular frame and has an engaging hole 93A in the center of the frame.

[0063] As shown in Figure 4, each second engaging portion 93 is formed to be engageable with each first engaging portion 73. Each second engaging portion 93 is engaged with the engaging surface 73B of each first engaging portion 73 along the first axis X. The first engaging portion 73 and the second engaging portion 93 are engaged with each other, for example, by a snap-fit ​​method utilizing the elastic deformation of the second engaging portion 93. The engagement of these first engaging portions 73 and second engaging portions 93 maintains the assembled state (joined state) of the cover body 70 and the retainer 90.

[0064] As shown in Figure 5, the retainer 90 has through holes 93B provided adjacent to each second engaging portion 93. The through holes 93B are located inside the fitting portion 92. The through holes 93B are formed to penetrate the second base portion 91 along the first axis X. The through holes 93B are formed to communicate with the engaging holes 93A of the second engaging portion 93. By providing the through holes 93B, the second engaging portion 93 can be elastically deformed appropriately.

[0065] As shown in Figure 3, the retainer 90 of this embodiment has four holes 94. The four holes 94 are located on the first axis X, opposite to the four protrusions 74. Each hole 94 is located near the second engaging portion 93. Two holes 94 are provided near each of the two second engaging portions 93. That is, a pair of holes 94 are provided for each second engaging portion 93. The pair of holes 94 are located on the third axis Z, sandwiching the second engaging portion 93 between them. Each hole 94 is located on the second protrusion 91A of the second base portion 91.

[0066] As shown in Figure 7, each hole 94 is formed so as to penetrate the second projection 91A along the first axis X. Each projection 74 is inserted into the interior of each hole 94. Thus, each of the two holes 94 provided near each second engaging portion 93 has a projection 74 inserted into it.

[0067] As shown in Figure 5, the second reinforcing rib 95 is provided in the internal space of the fitting portion 92. The second reinforcing rib 95 is formed to protrude in the rearward direction X2 from the end face of the closing portion 91B in the rearward direction X2. The amount of protrusion of the second reinforcing rib 95 from the second base portion 91 is smaller than the amount of protrusion of the fitting portion 92 from the second base portion 91. In this embodiment, the planar shape of the second reinforcing rib 95 when viewed in the forward direction X1 is formed in a grid or lattice pattern.

[0068] Specifically, the second reinforcing rib 95 of this embodiment has two third ribs 95A extending along the second axis Y and two fourth ribs 95B extending along the third axis Z. The two third ribs 95A are arranged side by side along the third axis Z. Each third rib 95A extends from the inner surface of one second short side portion 92B of the fitting portion 92 to the inner surface of the other second short side portion 92B. Each third rib 95A is formed in a continuous and integral manner with the second short side portion 92B. Each third rib 95A is formed to cross the two fourth ribs 95B. As shown in Figure 6, each third rib 95A is provided, for example, opposite the first rib 75A of the cover body 70 along the first axis X. The amount of protrusion of each third rib 95A is set so that, when the retainer 90 is assembled to the cover body 70, the tip surface of the third rib 95A (in this case, the tip surface in the rear direction X2) does not come into contact with the tip surface of the first rib 75A (in this case, the tip surface in the front direction X1). In other words, a gap is provided between the tip surface of each third rib 95A and the tip surface of each first rib 75A.

[0069] As shown in Figure 5, the two fourth ribs 95B are arranged side by side along the second axis Y. Each fourth rib 95B extends from the inner surface of one second long side portion 92A of the fitting portion 92 to the inner surface of the other second long side portion 92A. Each fourth rib 95B is formed integrally with the second long side portion 92A. Each fourth rib 95B is formed to cross the two third ribs 95A. As shown in Figure 4, each fourth rib 95B is provided, for example, opposite the second rib 75B of the cover body 70 along the first axis X. The amount of protrusion of each fourth rib 95B is set so that, when the retainer 90 is assembled to the cover body 70, the tip surface of the fourth rib 95B (here, the end surface in the rear direction X2) does not come into contact with the tip surface of the second rib 75B (here, the end surface in the front direction X1). In other words, a gap is provided between the tip surface of each fourth rib 95B and the tip surface of each second rib 75B.

[0070] As shown in Figure 5, the retainer 90 has one or more (eight in this embodiment) fitting recesses 96 provided in the fitting portion 92. The eight fitting recesses 96 are spaced apart in the circumferential direction of the fitting portion 92. Each fitting recess 96 is formed to recess from the end face of the fitting portion 92 in the rear direction X2 toward the front direction X1. Each fitting recess 96 is formed to recess, for example, to the end face of the second reinforcing rib 95 in the rear direction X2 along the first axis X.

[0071] As shown in Figure 8, a first reinforcing rib 75 is fitted into each fitting recess 96. Of the eight fitting recesses 96, the first rib 75A is fitted into four fitting recesses 96 located on the second short side portion 92B. The inner surfaces of these four fitting recesses 96 located on the second short side portion 92B can contact the first rib 75A in the first width direction Z1 and can also contact the first rib 75A in the second width direction Z2. Of the eight fitting recesses 96, the second rib 75B is fitted into four fitting recesses 96 located on the second long side portion 92A. The inner surfaces of these four fitting recesses 96 located on the second long side portion 92A can contact the second rib 75B in the upward direction Y1 and can also contact the second rib 75B in the downward direction Y2.

[0072] The retainer 90 has one or more (four in this embodiment) crushing ribs 97. Each crushing rib 97 is provided on the outer surface of the fitting portion 92. Each crushing rib 97 extends along the fitting direction (here, rearward X2) of the fitting portion 92 to the insertion portion 72. As shown in Figure 5, each crushing rib 97 extends from the end face of the second base portion 91 in the rearward X2 direction to the middle of the fitting portion 92 in the height direction along the rearward X2 direction.

[0073] As shown in Figure 8, the four crushing ribs 97 are provided at intervals in the circumferential direction of the fitting portion 92. The four crushing ribs 97 are provided on the outer surface of the second long side portion 92A of the fitting portion 92. With these crushing ribs 97 provided, when the fitting portion 92 is inserted into the insertion portion 72, each crushing rib 97 is crushed as it is inserted, and the fitting portion 92 is inserted into the insertion portion 72 in a substantially press-fit state. When the fitting portion 92 is inserted into the insertion portion 72, the crushing ribs 97 are crushed by the inner surface of the insertion portion 72, thereby crushing the crushing ribs 97 against the inner surface of the insertion portion 72. This suppresses rattling between the insertion portion 72 and the fitting portion 92, and consequently suppresses rattling between the cover body 70 and the retainer 90.

[0074] As shown in Figure 3, the retainer 90 has one or more (two in this embodiment) positioning recesses 98. Each positioning recess 98 is provided so as to face each positioning projection 81 of the sealing member 80 along the first axis X. Two positioning projections 81 are fitted into the two positioning recesses 98, respectively. Here, the sealing member 80 is positioned circumferentially relative to the retainer 90 by the fitting of the two positioning projections 81 into the two positioning recesses 98, respectively.

[0075] Each positioning recess 98 is provided on the second projection 91A. Each positioning recess 98 is formed to recess inward from the outer circumferential surface of the second projection 91A. Each positioning recess 98 is formed to cut out the outer circumferential surface of the second projection 91A. The inner surface of each positioning recess 98 can contact the positioning projection 81 in the upward direction Y1 and can also contact the positioning projection 81 in the downward direction Y2. This prevents the sealing member 80 from moving upward in the upward direction Y1 and downward in the downward direction Y2 relative to the retainer 90. Therefore, it is possible to prevent the sealing member 80 from rotating relative to the retainer 90.

[0076] As shown in Figure 2, the cover member 60 described above is assembled to the shield shell 41 along the forward direction X1 with the sealing member 80 and retainer 90 attached to the cover body 70. The cover member 60 is fixed to the shield shell 41 by screws B1.

[0077] (Effects of this embodiment) Next, the effects and advantages of this embodiment will be explained. (1) The connector 20 has conductive terminals 30 and a metal shield shell 41 that covers the terminals 30. The connector 20 has a cover member 60 attached to the shield shell 41 along a first direction (here, forward direction X1) so as to close an opening 42 provided in the shield shell 41. The cover member 60 has a metal cover body 70 having a first base portion 71 that closes the opening 42, a frame-shaped insertion portion 72 that protrudes from the first base portion 71 toward the forward direction X1 and is inserted into the interior of the shield shell 41, and a first engaging portion 73. The cover member 60 has an annular sealing member 80 attached to the outer circumference of the insertion portion 72 and that seals the space between the insertion portion 72 and the shield shell 41. The cover member 60 has a synthetic resin retainer 90 attached to the cover body 70 that prevents the sealing member 80 from coming off the insertion portion 72. The retainer 90 has a second engaging portion 93 formed to be engageable with the first engaging portion 73.

[0078] In this configuration, the cover member 60 attached to the shield shell 41 comprises a metal cover body 70 having an insertion portion 72 inserted into the interior of the shield shell 41, and a sealing member 80 attached to the outer circumference of the insertion portion 72. The cover member 60 also has a synthetic resin retainer 90 that prevents the sealing member 80 from coming loose. Therefore, the retainer 90, which is a separate part from the cover body 70, can prevent the sealing member 80 from coming loose from the insertion portion 72. Consequently, there is no need to provide a structure, such as a protrusion, at the tip of the insertion portion 72 of the cover body 70 to prevent the sealing member 80 from coming loose. For this reason, the cover body 70 can be manufactured without using a slide mold. This effectively prevents the formation of burrs on the outer surface of the insertion portion 72, i.e., the sealing surface, eliminating the need for cutting to remove burrs. Consequently, it is possible to prevent minute steps caused by cutting from occurring on the sealing surface. As a result, the sealing performance of the sealing member 80 can be improved compared to the case where a protrusion is provided at the tip of the insertion portion 72, and consequently, the waterproof performance of the connector 20 can be improved.

[0079] (2) The second engaging portion 93, which engages with the first engaging portion 73, is formed to be elastically deformable in a second direction perpendicular to the first direction (here, the upward direction Y1 or the downward direction Y2). Here, since the cover body 70 is made of metal and the retainer 90 is made of synthetic resin, the cover body 70 and the retainer 90 have different coefficients of thermal expansion. Due to this difference in coefficients of thermal expansion, the retainer 90 may shrink more than the cover body 70. In this case, if the retainer 90 shrinks significantly in the second direction, there is a risk that the engagement between the first engaging portion 73 and the second engaging portion 93 may be unintentionally released.

[0080] In contrast, the connector 20 has a pair of protrusions 74 on the cover body 70 that sandwich the first engaging portion 73, and a pair of holes 94 in the retainer 90 into which the pair of protrusions 74 are fitted. Furthermore, the inner surface of each hole 94 is provided so as to be able to contact the metal protrusions 74 in a second direction. This contact between each hole 94 and the protrusions 74 suppresses thermal contraction of the retainer 90 in the second direction near the first engaging portion 73 and the second engaging portion 93. As a result, it is possible to suppress large thermal contraction of the second engaging portion 93 in the second direction. This effectively prevents the engagement between the first engaging portion 73 and the second engaging portion 93 from being unintentionally released due to thermal contraction of the retainer 90.

[0081] (3) The fitting portion 92, which has an outer surface that conforms to the inner surface of the insertion portion 72, is fitted to the inside of the insertion portion 72. Therefore, the retainer 90 can be attached to the cover body 70 while fitting the fitting portion 92 to the inside of the insertion portion 72. Thus, the retainer 90 can be attached to the cover body 70 while aligning it by fitting the fitting portion 92 to the insertion portion 72. As a result, the workability when attaching the retainer 90 to the cover body 70 can be improved.

[0082] (4) The retainer 90 is assembled to the cover body 70 by the engagement of the first engagement portion 73 and the second engagement portion 93, which utilizes the elastic deformation of the second engagement portion 93. As a result, there is some looseness between the cover body 70 and the retainer 90. This looseness can cause abnormal noise to be generated during vibration.

[0083] In contrast, the connector 20 has a crimping rib 97 on the outer surface of the mating portion 92. The crimping rib 97 is press-fitted into the inside of the insertion portion 72. With this configuration, when the mating portion 92 is fitted inside the insertion portion 72, the crimping rib 97 is crushed by the inner surface of the insertion portion 72, thereby crushing the crimping rib 97 against the inner surface of the insertion portion 72. This suppresses rattling between the insertion portion 72 and the mating portion 92, and consequently suppresses rattling between the cover body 70 and the retainer 90.

[0084] (5) The sealing member 80 is provided between the first protrusion 71A of the first base 71 of the cover body 70 and the second protrusion 91A of the second base 91 of the retainer 90. This allows the movement of the sealing member 80 in a first direction (here, the forward direction X1) and a first opposite direction (here, the backward direction X2) to be restricted by the second protrusion 91A and the first protrusion 71A. Therefore, it is possible to effectively prevent the sealing member 80 from detaching from the insertion portion 72.

[0085] (6) The cover body 70 has a first reinforcing rib 75 formed to protrude in the forward direction X1 from the end face of the first base portion 71 in the forward direction X1. By providing such a first reinforcing rib 75, the rigidity of the cover body 70 can be increased. The retainer 90 also has a second reinforcing rib 95 formed to protrude in the rearward direction X2 from the end face of the closing portion 91B in the rearward direction X2. By providing such a second reinforcing rib 95, the rigidity of the retainer 90 can be increased.

[0086] (7) A gap is provided between the end face of the first reinforcing rib 75 in the forward direction X1 and the end face of the second reinforcing rib 95 in the rear direction X2. With this configuration, when the retainer 90 is attached to the cover body 70, the first reinforcing rib 75 and the second reinforcing rib 95 do not come into contact with each other. Therefore, it is possible to suppress the generation of abnormal noise caused by contact between the first reinforcing rib 75 and the second reinforcing rib 95.

[0087] (8) The first reinforcing rib 75 is fitted into a fitting recess 96 provided on the end face of the fitting portion 92 in the rear direction X2. At this time, the inner surface of the fitting recess 96 can contact the first reinforcing rib 75 in a direction intersecting the front direction X1, so that the retainer 90 can be prevented from moving in the direction intersecting the front direction X1. This effectively prevents the retainer 90 from tilting relative to the cover body 70.

[0088] (9) The positioning projection 81 of the sealing member 80 is fitted into the positioning recess 98 provided in the retainer 90. At this time, since the positioning projection 81 can contact the inner surface of the positioning recess 98 in a second direction (here, the upward direction Y1 or the downward direction Y2), it is possible to suppress the movement of the sealing member 80 in the second direction. This makes it possible to suppress the rotation of the sealing member 80 relative to the retainer 90.

[0089] (Example of change) 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.

In this case, the second engaging portion 93 of the retainer 90 is provided on the second long side portion 92A. In this case, it is preferable to provide the two protrusions 74 so as to sandwich the first engaging portion 73 between them along the second axis Y.
