The restricting protrusion 67 is integrally formed, the outer wall surface of the female connector housing 68 is brought into contact with the surface of the restricting protrusion 67 without any gap, and the rattling of the connectors 63 and 65 in the fitting orthogonal direction is restricted. It is a thing.
[0003]
The male connector housing 64 includes a male inner housing 64a and a rectangular cylindrical hood portion 64b outside the male housing. A female terminal 62 is accommodated in the inner housing 64a. The female terminal 62 is double-locked by a synthetic resin front holder 69. A waterproof packing 71 is attached to the base of the inner housing 64a. The rattling restricting projection 67 has a substantially rectangular shape.
[0004]
A female connector housing 68 is inserted between the hood portion 64b and the inner housing 64a. FIG. 6 shows a state immediately before fitting. The male and female terminals 62 and 70 are connected simultaneously with the fitting of the two connector housings 64 and 68, the tip of the female connector housing 68 is in close contact with the packing 71, and the lock arm 72 of the hood portion 64b is the female connector housing. The two connectors 63 and 65 are locked by engaging with the engaging projections 74 of the connector 68, and the rattling of the connector connector orthogonal direction between the hood portion 64a of the male connector housing 64 and the female connector housing 68 is restricted. 67, and the wear of the male and female terminals 62, 70 due to vibrations during traveling of the vehicle is reduced.
[0005]
However, in the conventional connector 61, although the rattling in the connector fitting orthogonal direction is restricted, the rattling in the connector fitting direction is not regulated. There is a problem in that both the male and female terminals 62 and 70 are rubbed with each other through the connector 61, resulting in abrasion and abrasion corrosion.
[0006]
Further, since the rattling restricting protrusion 67 protrudes from the inner surface of the hood part 64a, the hood part 64a and the female connector housing 68 come into contact with each other via the restricting protruding part 67, and the rattling is restricted. Although the inner housing 64a which is the terminal accommodating portion of the male connector housing 64 and the female connector housing 68 are not in contact with each other, rattling of the inner housing 64a is not directly prevented, There was a concern that rattling occurred on the male / female terminals 62 and 70 and the wear of both terminals 62 and 70 could not be completely eliminated.
[0007]
Furthermore, when used for a long period of time, the rattling restricting projection 67 is worn away by vibration during vehicle travel, and a gap is formed between the hood portion 64b and the outer wall surface of the other connector housing 68. There was also a concern that rattling could occur in the direction perpendicular to the fitting.

The hood 25 is an outer wall that surrounds the inner housing 15 from the outside. A protective wall 26a is formed on the upper wall portion 26 of the hood 25 to protect the locking arm 23 from external interference. Guide grooves 27 a and 28 a for the guide ribs 49 a and 49 b of the female connector housing 48 are formed in the lower wall portion 27 and the one side wall 28 of the hood 23, respectively. By forming the guide grooves 27a and 28a at positions orthogonal to each other, the female connector housing 48 is positioned in the vertical direction x and the horizontal direction y so that the connector housings 13 and 48 can be smoothly fitted. It has become.
[0027]
A substantially annular gap 29 is formed between the inner housing 15 and the hood 25. In this gap 29, the wedge ring 42 and the spring packing 31 are accommodated, and the peripheral wall 49 of the female connector housing 48 is inserted.
[0028]
The wedge ring 42 as a rattling restricting member is formed by resin molding and a plurality of abutting portions 43 each having an inwardly inclined surface 43a at a rear end portion thereof are connected by a connecting band (connecting portion) 44. The wedge ring 42 is movably mounted on the outer wall surface of the inner housing 15, and the front end abuts against the rear end of the spring packing 31, thereby preventing the wedge ring 42 from coming out forward.

The wide contact portions 43 are formed one by one on the top and the bottom, and two each on the left and right. The contact portion 43 has a trapezoidal cross section, and has a rearward inwardly inclined surface 43a, a circumscribed surface 43b that continues to the inclined surface 43a, a vertical front end surface 43c that continues across the circumscribed surface 43b, and both side surfaces. 43d, 43d, and inscribed surface 43e. The inclined surface 43a contacts the outwardly inclined surface 24 (FIG. 2) formed on the inner side of the inner housing when the two connector housings 13 and 48 are fitted. Thereby, rattling in the connector fitting direction is regulated.
[0030]
The circumscribed surface 43 b contacts the inner peripheral surface of the peripheral wall 49 of the female connector housing 48. The front end face 43 c abuts on the rear end face 31 b of the spring packing 31. A connecting band 44 is connected to both side surfaces 43d and 43d. The inscribed surface 43e is curved so as to follow the outer wall surface of the inner housing 15.

The connection band 44 is formed narrower than the contact portion 43 so that the wedge ring 42 is easily elastically deformed. For this reason, the circumscribed surface 43 b of the abutting portion 43 is easily in close contact with the inner peripheral surface of the peripheral wall 49 of the female connector housing 48. In addition, the wedge ring 42 can be easily assembled and can be prevented from falling off during the assembly.
[0032]
The wedge ring 42 is preferably formed of a soft material that is easily elastically deformed, such as synthetic rubber or elastomer resin. When formed of such a material, even if there is an angle error between the inclined surface 43a of the wedge ring 42 and the inclined surface 24 of the inner housing 15, the error is absorbed and the contact is made without a gap. In addition, a dimensional error in the radial direction is also absorbed, and curved deformation follows the inner peripheral surface of the peripheral wall 49 of the female connector housing 48, so that the adhesion between the outer surface 43 b of the wedge ring 42 and the inner peripheral surface of the peripheral wall 49 is improved. Will also improve. Furthermore, vehicle body vibration and other vibrations (longitudinal vibration, lateral vibration) while the vehicle is traveling are absorbed by the wedge ring 42 to prevent the vibration from being transmitted to the male and female terminals 33 and 55 in the inner housing 15. .

By projecting the front end side of the spring packing 31, the inner wall 52 a of the female connector housing 48 abuts on the front end surface 31 c of the spring packing 31, and the wedge ring 42 is pushed into the inner side through the spring packing 31. It has become.
[0034]
On the outer surface of the spring packing 31, two bumps 31 a and 31 a that are in close contact with the inner peripheral surface of the peripheral wall 49 of the female connector housing 48 are formed. On the inner surface, a protrusion (locking portion) 31 d (FIG. 4) for preventing the spring packing 31 from coming out is formed at a position corresponding to the hole portion 15 b of the inner housing 15. Since the protrusion 31d is located on the opposite side of the hump 31a, the hump 31a is strongly locked by being pushed by the peripheral wall 49 of the female connector housing 48.
[0035]
The rear end surface 31 b of the spring packing 31 is a contact surface that contacts the front end surface 43 c of the wedge ring 42. The front end surface 31 c is a contact surface that contacts the back wall 52 a of the female connector housing 15.

When the wedge ring 42 and the spring packing 31 are respectively attached to the inner housing 15 and the connector housings 13 and 48 are fitted, the rear wall 52a of the female connector housing 48 comes into contact with the front end face 31c of the spring packing 31. The spring packing 31 is compressed and the two bumps 31 a abut against the peripheral wall 49 of the female connector housing 48. The wedge ring 42 is pushed into the back side by the spring packing 31, abuts against the inclined surface 24 of the inner housing 15, and the inclined surface 24 and the peripheral wall 49 of the female connector housing 48 closely contact each other via the wedge ring 42. . As a result, the two connector housings 13 and 48 are regulated in two directions, ie, the connector fitting direction and the fitting orthogonal direction, and wear of the male and female terminals 33 and 55 due to vibration is prevented. Yes. Further, when the wedge ring 42 and the spring packing 31 are made of a soft material having high vibration absorption, the wedge ring 42 attenuates longitudinal vibration in the connector fitting orthogonal direction, and the spring packing 31 dampens the connector fitting direction. The lateral vibration of the inner housing 15 is limited to be transmitted to the male and female terminals 33 and 55 in the inner housing 15.

A female connector housing 48 is composed of a substantially rectangular annular peripheral wall 49. A female connector 47 is constituted by the male terminal 55 and the female connector housing 48 protruding into the connector fitting chamber 52 on the front side of the peripheral wall 49.
[0038]
A locking projection 54 that abuts on the locking surface 23 b of the locking arm 23 is formed on the upper wall portion of the peripheral wall 49. The locking projection 54 has an inclined surface 54a and a vertical locking surface 54b following the inclined surface 54a (FIG. 4). Since the vertical locking surface 54b abuts on the locking surface 23b of the locking arm 23, both the connector housings 13 and 48 are locked.
[0039]
A connector fitting chamber 52 exists inside the peripheral wall 49, and the inner housing 15 of the male connector housing 13 is fitted therein (FIGS. 2 and 3). The inner wall 52 a of the connector fitting chamber 52 is in contact with the front end surface 31 c of the spring packing 31 protruding from the front end surface 15 a of the inner housing 15.
[0040]
The female connector 47 is not an existing female connector housing 48 that has been changed in shape or newly provided. Therefore, according to the present invention, an existing connector housing can be applied to the female connector housing 48, and the investment amount can be reduced by using a common connector housing.
[0041]
