Description

  The present invention relates to a cable connector for connecting a cable and an electronic device or the like.

A conventional example of a cable connector for connecting a cable and an electronic device is disclosed in Patent Document 1.
This cable connector is for connecting a cable and an in-vehicle camera module, and includes a contact, a contact support member, a receiving member, and a resin coating as major components.
The contact has a crimping portion that crimps the end of the cable core on one end side, and a contact portion (contact portion) that can contact the contact of the camera module on the other end side. Further, a supported portion (base portion) is formed between the crimping portion and the contact portion, and a locking portion (engagement portion) protrudes from the crimping portion.
The contact support member includes a locking groove (engaged portion) into which the locking portion (engagement portion) is press-fitted (engaged), and a contact portion recess for storing the contact portion (contact portion). Yes.
The receiving member has a receiving hole for receiving the contact support member (and the contact supported by the contact support member).
The resin sheath (code bush) made of resin material is molded to each of these members so as to straddle the crimped part of the contacts assembled together, the end of the cable core, the contact support member, and the receiving member. When the resin coating portion is molded, the contact crimping portion and the end of the wire core are covered with the resin coating portion.

  When the in-vehicle camera module is connected to the cable connector having the above configuration, the contact pin of the camera module is connected to the contact portion of the contact. As a result, since the power of the battery mounted on the vehicle is supplied to the camera module via the cable connector (contact), photographing (imaging) by the camera module becomes possible.

Since the cable connector is mounted on a vehicle, vibrations generated during the traveling of the vehicle are transmitted from the vehicle to the cable connector. However, since the crimping part of the contact, the cable (the end of the core), the contact support member, and the receiving member are firmly fixed to each other by the resin coating part made of resin material, each component of the cable connector is vibrated by vibration. There is little risk that the parts will be separated from each other or that the connection state (crimped state) between the contact and the cable will become unstable.
In addition, since the in-vehicle camera module is attached to the outside of the vehicle (the surface of the vehicle), there is a possibility that moisture (rain water, etc.) outside the vehicle adheres to the cable connector. However, since the resin-coated portion covers the crimping portion of the contact and the end portion of the wire core, the possibility that the moisture adheres to the crimping portion of the contact and the end portion of the wire core is small.

Japanese Patent No. 4590467

In the cable connector described above, since the resin coating portion made of a resin material is put on the contact, the cable (the end of the wire core), the contact support member, and the receiving member, before the resin coating portion is solidified, There is a possibility that the resin coating portion (resin material) flows to the contact portion side through the surface of the contact supported portion (base portion).
If the resin material is solidified on the surface of the contact portion, the contact pin of the camera module may not be connected to the contact portion of the camera module when the in-vehicle camera module is connected to the cable connector.

  An object of the present invention is to form a resin coating on a contact connecting portion, a cable end, a contact support member, and a receiving member, and the resin material is a surface of the contact supported portion. An object of the present invention is to provide a cable connector that can effectively reduce the risk of flowing through the contact portion side.

  A first end of the contact support member, which is opposed to the receiving hole, has an open end facing the receiving hole, and an inner surface of the contact supporting member that forms the first supporting portion. A contact support groove is formed, and the inner surface of the receiving hole of the receiving member is fitted into the first contact support groove through the opposing end portion, and the end portion on the protruding end side forms the second support portion. A support protrusion may be provided.

  A second end of the contact support member, which is opposed to the receiving hole, has an open end facing the receiving hole, and an inner surface of the contact supporting member that forms the first supporting portion. A contact support groove is formed, and the opposing surface of the contact support member and the surface of the supported portion fitted in the second contact support groove are located on the same plane, and the inner surface of the receiving hole of the receiving member Furthermore, the contact support member may be in contact with the facing surface and the surface of the supported portion, and a part of the contact support member may form a contact plane constituting the second support portion.

  The contact support member includes two first support portions spaced apart in the extension direction of the contact, and the receiving member is separated in the extension direction and corresponds to the first support portions. You may provide a support part.

  The contact includes a locking portion for fixing the contact to the contact support member by press-fitting into a locking groove provided in the contact support member. You may position the said latching | locking part between two support parts and the said other 1st support part and said 2nd support part.

  The first support portion of the first contact support groove and the second support portion of the support protrusion constitute one of the first support portion and the second support portion, respectively, and the second contact support groove The first support part and the second support part on the contact plane may constitute the other first support part and the second support part, respectively.

In the present invention, the resin coating portion is formed so as to straddle the contact connection portion, the cable end portion, the contact support member connection portion storage portion, and the receiving member, and the connection portion and the cable end are formed by the resin coating portion. The part is covered.
Then, a part of the outer peripheral surface of the supported part of the contact is supported in contact with the first support part of the contact support member, and the part of the outer peripheral surface of the supported part of the contact is supported with the second support part of the receiving member. Support the whole part in contact. That is, the contact support member (first support portion) and the receiving member (second support portion) are brought into contact with the entire outer peripheral surface of the supported portion located between the contact connecting portion and the contact portion.
Therefore, there is almost no possibility that the (liquid) resin coating portion (resin material) before solidifying flows to the contact portion side through the surface of the contact supported portion. Therefore, when another contact is connected to the cable connector, it is possible to almost eliminate the possibility that the contact between the other contact and the contact portion of the contact is hindered by the resin material.

The portion of the contact support member 31 excluding the fitting key 32 is bilaterally symmetric and vertically symmetric. A crimping portion accommodating portion 33 is formed at the rear portion of the contact support member 31, and the surface of the crimping portion accommodating portion 33 (an end concave portion 56 and a rear concave portion which will be described later when the contact supporting member 31 is attached to the receiving member 50). On the “opposite surface” facing the inner surface of 59, there are formed six crimping portion accommodating recesses 34 (connection portion accommodating portions) partitioned from each other by walls. On the other hand, a contact portion storage portion 35 is formed in the front portion of the contact support member 31, and six contact portion storage recesses 36 that are partitioned from each other by a wall are formed in the contact portion storage portion 35. Both the upper end surface and the lower end surface of the rear wall of the contact portion storage portion 35 are configured by a contacted flat surface 35a orthogonal to the vertical direction. Six first contact support grooves 37 communicating with the respective crimping portion accommodating recesses 34 are formed on the upper end surface and the lower end surface of the front wall of the crimping portion accommodating portion 33, and the first contact support grooves 37 on the upper and lower contact surfaces 35 a Six second contact support grooves 38 positioned immediately before the contact support grooves 37 are formed. Further, the contact support member 31 includes a bottom surface of the first contact support groove 37 that extends in the front-rear direction from the front wall of the crimping portion storage portion 33 to the rear wall of the contact portion storage portion 35 and is aligned in the front-rear direction, and the second contact support. A support plane 39 constituting the bottom surface of the groove 38 is formed. Further, contact locking grooves 40 (locking grooves) positioned on both the left and right sides of each support plane 39 are formed as a pair of left and right at a portion positioned between the first contact support groove 37 and the second contact support groove 38 arranged in the front-rear direction. It is formed. The upper contact locking groove 40 extends downward, and the lower contact locking groove 40 extends upward.

The six receptacle contacts 42 (contacts) are integrally formed by stamping and bending a metal plate material of a uniform thickness made of a copper alloy having spring elasticity (for example, phosphor bronze, beryllium copper, titanium copper, etc.) or a Corson copper alloy. It is a molded product, and the surface is plated with nickel and then plated with gold or tin.
The receptacle contact 42 includes a base portion 43 (supported portion) linearly extending in the front-rear direction, a pair of left and right coated tube crimping portions 44 (connecting portions) projecting from the rear end of the base portion 43, and a rear portion (covered tube). A pair of left and right core wire crimping portions 45 (connecting portions) projecting from the crimping portion 44 (a portion located in front of the connecting portion), and a pair of left and right engaging portions 46 extending downward from the vicinity of the center of the base portion 43, A pair of left and right front end bent portions 47 extending downward from the front end of the base portion 43 and a pair of left and right contact portions 48 extending rearward from the left and right front end bent portions 47 are provided.
The coated tube crimping portion 44 and the core wire crimping portion 45 extend in the left-right direction (not shown) so as to open the lower side when the receptacle contact 42 is formed (during the bending process). A locking projection 46 a is provided on the front surface of the locking portion 46. The left and right front end bent portions 47 have a substantially square shape when viewed from the front, and the contact portion 48 can be elastically deformed in the left-right direction.

The cable 25 connected to the receptacle contact 42 includes six core wires 26 (metal wire strands), a covering tube 27 made of an insulating material that covers the surface of each core wire 26, and six sheaths. A cylindrical metal (for example, copper or aluminum) shielding member (not shown) made of a net or thin film that covers the outer peripheral surface of the unitary body in which the tube 27 (core wire 26) is bundled, and the outer peripheral surface of the shielding member. And a sheath 28 made of an insulating material, which has flexibility as a whole.
The cable 25 removes (cuts out) one end portion of the sheath 28 to expose the shielding member. Next, the shield member is cut off at a predetermined length to expose one end portion of the six coated tubes 27, and further, one end portion of the coated tube 27 is removed (removed) and one end portion of the six core wires 26 is removed. , The one end of each coated tube 27 (the part adjacent to the removed portion) is positioned between the left and right coated tube crimping portions 44 and the one end of the core wire 26 is crimped to the left and right core wires. It is located between the parts 45. In this state, the left and right coated tube crimping portions 44 and the left and right core wire crimping portions 45 are plastically deformed in a direction approaching each other by using a jig or the like not shown in FIGS. 7, 9, 10, and 15. The right and left coated tube crimping portions 44 are crimped to one end portion of the coated tube 27 from the outer peripheral side, and the left and right core wire crimping portions 45 are crimped to one end portion of the core wire 26. 26 and one end of the covering tube 27 are fixed to the receptacle contact 42.

  The cable 25 and the receptacle contact 42 integrated in this way are connected to the base 43 of the receptacle contact 42 by the six support planes 39 of the contact support member 31 (the bottom surfaces of the first contact support groove 37 and the second contact support groove 38). ) While making surface contact with the (first support portion) (see FIGS. 18 to 21), the left and right locking portions 46 are press-fitted into the corresponding left and right contact locking grooves 40, and each locking protrusion 46a is inserted. The inner surface of the corresponding contact locking groove 40 is bitten, and the portions of the base portions 43 positioned before and after the locking portion 46 are fitted into the first contact support groove 37 and the second contact support groove 38, respectively. Thus, the contact support member 31 is fixed. The coated tube crimping portion 44 and the core wire crimping portion 45 of each receptacle contact 42 are housed in each crimping portion housing recess 34, and the front end bent portion 47 and the contact portion 48 are housed in each contact portion housing recess 36. The left and right side surfaces (first support portions) of the corresponding first contact support groove 37 are in contact with the left and right side surfaces of the portion fitted in the first contact support groove 37 of each base portion 43. On the other hand, the left and right side surfaces (first support portions) of the corresponding second contact support groove 38 are in contact with the left and right side surfaces of the portion fitted in the second contact support groove 38 of each base portion 43 (see FIG. 21). Further, the upper surface of the portion of the upper base 43 and the lower surface of the portion of the lower base 43 are located on the same plane as the upper and lower contact planes 35a (opposing surfaces) (see FIGS. 16 and 21).

The integrated structure of the cable 25, the receptacle contact 42, and the contact support member 31 configured as described above is accommodated in a receiving member 50 (receptacle insulator) that is a resin-made (insulating material) molded product.
The receiving member 50 includes a pair of upper and lower retaining projections 51, and an engaging claw 52 is formed at each end of the upper and lower retaining projections 51. On the left side of the rear surface of the receiving member 50, there is provided a side protruding piece 53 protruding rearward, and the side protruding piece 53 is formed with a cable escape recess 54 having a substantially semicircular cross section. The rear surface of the receiving member 50 is provided with a recessed portion 56 (receiving hole) having a substantially horizontally long shape when viewed from the rear, and a keyway having a rear end opened on the right side surface (right side portion of the inner surface) of the end recessed portion 56. 57 is formed. In front of the end recess 56, a back recess 59 (receiving hole) having a narrower vertical width than the end recess 56 is recessed forward. As shown in FIG. 27, FIG. 28, etc., the upper surface and the lower surface of the back-side recess 59 are contact planes 59a orthogonal to the vertical direction, and four crimps with rear ends open on the upper and lower contact planes 59a. The part accommodating part receiving grooves 60 are formed side by side in the left-right direction, and a total of six supporting protrusions 61 partitioning the adjacent crimping part accommodating part receiving grooves 60 between the adjacent crimping part accommodating part receiving grooves 60. Is provided. A total of six contact insertion holes 63 are formed on the front surface of the receiving member 50 so as to penetrate the front surface in the front-rear direction and communicate with the back-side concave portion 59. A ring is formed on the outer peripheral surface near the front end of the receiving member 50. A mounting groove 64 is recessed.
The integrated body of the cable 25, the receptacle contact 42 and the contact support member 31 is inserted into the end recess 56 and the back recess 59 from the rear of the receiving member 50. Specifically, after fitting the vicinity of one end (end on the contact support member 31 side) of the cable 25 in the left-right direction with the cable escape recess 54, the fitting key 32 of the contact support member 31 is pressed. The entire contact support member 31 (and the six receptacle contacts 42) is inserted into the end recessed portion 56 and the back recessed portion 59 while being fitted in the key groove 57, and the rear surface of the contact support member 31 and the receiving member 50 (side portion). The rear surface (excluding the projecting piece 53) is positioned on substantially the same surface.
Then, as shown in FIG. 31, each support protrusion 61 of the receiving member 50 is fitted to each first contact support groove 37 of the contact support member 31, and the left and right widths in the free state are the first contact support grooves. (Slightly larger than 37) the left and right sides of the support projection 61 are in contact with the left and right sides of the first contact support groove 37. Furthermore, the upper surface of the part fitted in the first contact support groove 37 of the base 43 of the upper receptacle contact 42 and the part fitted in the first contact support groove 37 of the base 43 of the lower receptacle contact 42. The tip surfaces of the support protrusions 61 (the lower end surface of the upper support protrusion 61 and the upper end surface of the lower support protrusion 61; the second support portion) are in surface contact with the lower surface. That is, the inner surface of the first contact support groove 37 and the front end surface of the support projection 61 are in contact with the entire outer peripheral surface of the portion of the six bases 43 that fits in the first contact support groove 37.
Further, as shown in FIG. 33, the upper surface of the portion of the base 43 of the upper receptacle contact 42 to be fitted into the second contact support groove 38 and the second contact support groove 38 of the base 43 of the lower receptacle contact 42 are fitted. The upper and lower contact planes 59a (second support portions) of the back-side recess 59 are in surface contact with the lower surface of the portion to be touched and the upper and lower contacted planes 35a. That is, the inner surface of the second contact support groove 38 and the contact flat surface 59a are in contact with the entire outer peripheral surface of the portion of the six base portions 43 that are fitted into the second contact support groove 38.
Further, as shown in FIG. 32, the upper surface of a portion located between the left and right engaging portions 46 of the base 43 of the upper receptacle contact 42 and the left and right engaging portions 46 of the base 43 of the lower receptacle contact 42 are also shown. The front end surfaces of the support projections 61 (the lower end surface of the upper support projection 61 and the upper end surface of the lower support projection 61) are in surface contact with the lower surface of the portion located at the position.

When an assembly including the cable 25, the receptacle contact 42, the contact support member 31, and the receiving member 50 is manufactured, the assembly is integrally formed using a mold (not shown) from a resin material (insulating material). An inner mold 67 (resin covering portion) (receptacle insulator) is formed integrally.
Since the inner mold 67 is integrally formed with the rear portion of the receiving member 50, a part of the resin material constituting the inner mold 67 is solidified from the liquid state until the end concave portion 56 and the back of the receiving member 50 are solidified. It flows into the side recess 59 and solidifies inside the end recess 56 and the back recess 59 (see FIG. 36). Therefore, it is located behind the first contact support groove 37 of each receptacle contact 42 and the crimp contact portion storage portion 33 (crimp portion storage recess 34) of the contact support member 31, the six core wires 26 and one end portions of the covering tube 27. The surface of the portion (the coated tube crimping portion 44, the core wire crimping portion 45, etc.) may be covered with the inner mold 67 inside the end recess 56 and the back recess 59. However, as described above, the inner surface of the first contact support groove 37 and the front end surface of the support protrusion 61 are in contact with the entire outer peripheral surface of the portion that fits into the first contact support groove 37 of the six bases 43 ( 31 (b)), the resin material before solidification is forward of the first contact support groove 37 and the support protrusion 61 and the outer surface of the base 43 from the first contact support groove 37 of each receptacle contact 42. There is almost no possibility that it will flow into the part side located in and solidify on the surface of these parts. Further, the inner surface of the second contact support groove 38 and the contact flat surface 59a are in contact with the entire outer peripheral surface of the portion of the six base portions 43 that fits into the second contact support groove 38, and the upper portion of the base portion 43 of the upper receptacle contact 42 is in contact. With respect to a large plane consisting of the upper surface of the portion that fits into the two contact support groove 38, the lower surface of the portion of the base 43 of the lower receptacle contact 42 that fits into the second contact support groove 38, and the upper and lower contact planes 35a Then, since the large plane (the upper and lower contact planes 59a) of the back-side recess 59 is in surface contact (see FIG. 33B), the resin material before solidification should be the first contact support groove 37 and the support protrusion. Even if the resin material flows into a part of the receptacle contact 42 that is located forward of the first contact support groove 37 from between the outer peripheral surface of the base member 43 and the outer peripheral surface of the base portion 43, the resin material may be Fear hardly flows into the portion side located in front of the second contact support groove 38 of each receptacle contact 42 from between the outer peripheral surface of the tact support groove 38 and the contact plane 59a and the base 43. Therefore, there is almost no possibility that the resin material before solidification contacts the contact portion 48 of each receptacle contact 42 and solidifies on the surface of the contact portion 48.
Further, when the inner mold 67 is solidified, the rear portion of the inner mold 67 constitutes a semi-cylindrical portion 68 positioned immediately after the side protrusion 53 (cable escape recess 54), and the cable escape recess 54 and the semi-cylindrical portion 68 are formed. Construct a circular hole. Further, the rear half part of the outer peripheral surface of the sheath 28 fitted into the cable escape recess 54 and the semi-cylindrical part 68 are integrated. As described above, the inner mold 67 (resin material) is solidified while being integrated with the cable 25, the contact support member 31, the receptacle contact 42, and the receiving member 50, so that the cable 25, the contact support member 31, and the receptacle contact 42 are solidified by the inner mold 67. And the receiving member 50 are firmly integrated.

When an integrated object including the cable 25, the receptacle contact 42, the contact support member 31, the receiving member 50, and the inner mold 67 is manufactured, a resin material (insulation) is integrally formed using a mold (not shown) on the integrated object. The outer mold 70 (resin covering portion) (receptacle insulator) made of a material is integrally molded.
As shown in FIGS. 38 to 41, the outer mold 70 may be a resin material (the same as or different from the inner mold 67. For example, in the present embodiment, the inner mold 67 uses a hard resin, while the outer mold 70 By solidifying the resin material such as rubber softer than the inner mold 67 from a liquid state, the entire surfaces of the receiving member 50 and the inner mold 67 are covered. However, although the outer mold 70 covers the entire outer peripheral surface of the upper and lower retaining projections 51, the upper and lower engaging claws 52 protrude from both the upper and lower surfaces of the outer mold 70. Further, since the front surface of the front cylindrical portion 71 constituting the front portion of the outer mold 70 is open, the front surface (contact insertion hole 63) of the receiving member 50 is exposed. An annular gap is formed between the peripheral surface and the outer peripheral surface of the front portion of the receiving member 50.
Side restriction grooves 72 extending in the front-rear direction are provided as a pair of left and right sides on the upper and lower surfaces of the outer mold 70. A cylindrical outer cylindrical portion 73 is formed on the left side of the front cylindrical portion 71 so as to cover the surface of the side protrusion 53 of the receiving member 50 and the semicylindrical portion 68 of the inner mold 67. The inner peripheral surface of the shaped portion 73 is integrated with the outer peripheral surface of the sheath 28 of the cable 25.
Thus, since the outer mold 70 (resin material) is solidified while being integrated with the cable 25 (sheath 28), the receiving member 50, and the inner mold 67, the cable 25 (sheath 28), the receiving member 50, and the outer mold 70 are solidified. The inner mold 67 is firmly integrated. Further, the cable 25 and the sheath 28 can be prevented from being peeled from the receptacle connector 30 by receiving or absorbing the force generated by pulling or bending the cable 25 with the outer mold 70.
With respect to the ring mounting groove 64 having the cable 25, the contact support member 31, the receptacle contact 42, the receiving member 50, the inner mold 67, and the outer mold 70, which is configured as described above, from the free state to the diameter increasing direction. When the elastically deformed O-ring 75 is attached, the receptacle connector 30 (integrated with the cable 25) is completed.

Next, how to use the plug connector 12 and the cable 25 will be described.
When a camera module (not shown) is fitted into the plug insulator 13 of the plug connector 12 and the two positioning projections 15 are press-fitted into the recess formed on the rear surface of the camera module, the plug connector 12 The camera module can be integrated in a fixed state.
Further, the fitting wall 18 of the plug connector 12 is fitted from the front into the annular gap between the inner peripheral surface of the front cylindrical portion 71 of the receptacle connector 30 and the outer peripheral surface of the front portion of the receiving member 50, and The upper and lower mounting pieces 16 of the plug connector 12 are fitted from the front between the left and right side restriction grooves 72 provided on the upper and lower sides of the receptacle connector 30 and the engaging claws 52 are engaged with the respective engaging holes 17. Then, the plug connector 12 and the receptacle connector 30 are connected to each other in a fixed state. Then, the rear part of the plug contact 21 of the plug connector 12 enters the back side recess 59 through the contact insertion hole 63 of the receiving member 50, and the left and right sides of the receptacle contacts 42 positioned in the contact part storage recess 36 of the contact support member 31. The left and right contact portions 48 are elastically deformed and come into contact with the inner surfaces (opposing surfaces) of the left and right contact portions 48. Furthermore, the inner peripheral surface of the fitting wall 18 contacts the O-ring 75 of the receptacle connector 30 in a watertight state.
The connector 10 formed by connecting the plug connector 12 and the receptacle connector 30 can be mounted on a vehicle not shown. Specifically, the two attachment pins 19 of the plug connector 12 can be attached to the vehicle by press-fitting into the attachment holes provided in the rear bumper of the vehicle, for example. Therefore, if the cable 25 is connected to the control means built in the car and the power of the battery built in the car is supplied to the cable 25 via the control means, the situation around the car can be photographed (captured) by the camera module. Is possible.

  As described above, the connector 10 of the present embodiment contacts the contact portion 48 of each receptacle contact 42 before the resin material constituting the inner mold 67 is solidified (when liquid), and the surface of the contact portion 48 is contacted. There is almost no possibility of solidifying. Therefore, when the plug connector 12 is connected to the receptacle connector 30, the contact between the rear portion of the plug contact 21 of the plug connector 12 and the contact portion 48 of the receptacle contact 42 of the receptacle connector 30 constitutes the inner mold 67. There is almost no risk of being disturbed by the resin material.

Further, the inner surfaces of the first contact support groove 37 and the second contact support groove 38 which are grooves for fixing the receptacle contact 42 to the contact support member 31 are brought into contact with the outer peripheral surface of the base portion 43 before being solidified (liquid state). The resin material is formed between the first contact support groove 37 and the support protrusion 61 and the outer peripheral surface of the base 43, and between the second contact support groove 38 and the contact flat surface 59a and the outer peripheral surface of the base 43. Inflow to the front of the receptacle contact 42 is prevented. Therefore, grooves (first contact support groove 37, second contact support groove 38) for fixing the receptacle contact 42 to the contact support member 31, and the (liquid) resin material is the first contact support groove 37 and the support protrusion. 61 and a groove for preventing the second contact support groove 38 and the contact plane 59a from flowing between the outer peripheral surface of the base portion 43 and the outer peripheral surface of the base portion 43 from flowing into the front of each receptacle contact 42; Compared with the case where the contact support member 31 is separately molded, the structure of the contact support member 31 (receptacle connector 30) can be simplified.
Further, since the first contact support groove 37 and the second contact support groove 38 are positioned in the vicinity of the contact locking groove 40 (locking portion 46), the base portions of the first contact support groove 37 and the second contact support groove 38 are provided. The contact state with respect to the outer peripheral surface of 43 is stabilized. Therefore, the (liquid) resin material before solidification is between the first contact support groove 37 and the support protrusion 61 and the outer peripheral surface of the base 43, and the second contact support groove 38 and the contact flat surface 59a and the base 43. It is possible to reliably prevent the fluid from flowing into the front of each receptacle contact 42 from between the outer peripheral surfaces.

Further, when the connector 10 (receptacle connector 30) is mounted on a vehicle, vibrations generated during traveling of the vehicle are transmitted from the vehicle to the connector 10 (receptacle connector 30). However, the cable 25, the contact support member 31, the receptacle contact 42, and the receiving member 50 (and the inner mold 67 and the outer mold 70) are firmly integrated (fixed) by the inner mold 67 and the outer mold 70 made of a resin material. Therefore, it is unlikely that the components of the receptacle connector 30 are separated from each other by vibration generated in the vehicle, and the connection state between the cable 25 (core wire 26) and the receptacle contact 42 is unstable.
Further, when the connector 10 is attached to the outside of the vehicle (for example, the surface of the bumper), there is a possibility that moisture (rain water or the like) outside the vehicle adheres to the connector 10. However, since the inner peripheral surface of the fitting wall 18 contacts the O-ring 75 of the receptacle connector 30 in a watertight state, the moisture enters the inside of the O-ring 75 from between the fitting wall 18 and the O-ring 75. There is almost no possibility that moisture adheres to the plug contact 21 through the contact insertion hole 63. Furthermore, even if a minute gap is formed between the receiving member 50, the inner mold 67, and the outer mold 70, and moisture enters the inside of the receptacle connector 30 from the gap, the inner mold 67 of the receptacle connector 30 may be used. Covers the surface of each receptacle contact 42 located behind the first contact support groove 37 (covered tube crimping portion 44, core wire crimping portion 45, etc.) and one end of each core wire 26 (covering tube 27). In this case, the moisture is located at a portion of the receptacle contact 42 located behind the first contact support groove 37 (covered tube crimping portion 44, core wire crimping portion 45, etc.) or one end of each core wire 26 (covering tube 27). There is almost no risk of adhesion.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to said each embodiment, It can implement, giving various deformation | transformation.
For example, the inner mold 67 (liquid state) is formed between the inner surface of the first contact support groove 37 and the front end surface of the support protrusion 61 and the outer peripheral surface of the base portion 43 (at a portion that fits into the first contact support groove 37). A minute gap (for example, 0.15 mm or less, more preferably 0.1 mm or less) may be formed so that the resin material cannot enter. Similarly, an inner mold 67 (liquid resin material thereof) is formed between the inner surface of the second contact support groove 38 and the contact flat surface 59a and the outer peripheral surface of the base portion 43 (at a portion that fits into the second contact support groove 38). A minute gap (for example, 0.15 mm or less, more preferably 0.1 mm or less) that does not allow entry may be formed. Even when these “gap” are provided, the inner surface of the first contact support groove 37, the state of the distal end surface of the support protrusion 61 and the outer peripheral surface of the base 43, the inner surface of the second contact support groove 38, and The state between the contact flat surface 59a and the outer peripheral surface of the base portion 43 is included in the “contact state” in the claims.
Further, the second contact support groove 38 (contact support member 31) and the contact plane 59a (receiving member 50) are brought into non-contact with the base 43 of the receptacle contact 42 and the contacted flat surface 35a, and the second contact support groove 38 and the contact flat surface are contacted. A gap into which the liquid resin material can flow may be formed between 59 a and the base portion 43.
Moreover, you may shape | mold the inner mold 67 and the outer mold 70 by one shaping | molding (one type of resin material).

The core wire crimping portion 45 of the receptacle contact 42 may be changed to a “pressure contact portion (connection portion)” that is connected to the core wire 26 while breaking the coated tube 27. The core wire crimping portion 45 may be changed to a “soldering portion (connection portion)” that is soldered to the end portion of the core wire 26.
Further, the O-ring 75 may be omitted from the receptacle connector 30.
The electronic device (electric device) attached to the plug connector 12 may be other than the camera module, or the receptacle connector 30 (connector 10) may be attached to an object (electric device, electronic device, etc.) other than the car.
