The electric wire waterproof packing 11 and the internal waterproof packing 12 of FIG. 1 are arranged so that a part or the whole of the inner annular recess 21 and the outer annular recess 22 are respectively inserted.

The electric wire waterproof packing 11 is a member that seals between the outer peripheral surface of the shielded electric wire 2 and the waterproof material holder 10, and is made of rubber or synthetic resin and is made of a ring-shaped member. The cross-sectional shape of the electric wire waterproof packing 11 is such that the outer peripheral surface of the shielded electric wire 2 and the waterproof material holder 10 are densely contacted with each other by being pushed into the inner annular recess 21 of the waterproof material holder 10 by the tightening holder 13. It is preferable that the shape is such that contact can be obtained. In this embodiment, as shown in FIGS. 7A and 4, a shape having a deformed portion relief recess 11a at a plurality of locations in the circumferential direction of the outer peripheral surface is provided. It is said that. The deformed portion relief recess 11a is a recess that facilitates deformation by releasing the elastically deformed portion of the electric wire waterproof packing 11.

In addition to this, as shown in FIGS. 7 (B) to 7 (D), the cross-sectional shape of the electric wire waterproof packing 11 is various, such as a rectangular shape, a conical trapezoidal shape having a tapered outer peripheral surface, and a circular shape.

The shield connecting spring 14 is a member that is interposed to enhance the contact between the end surface of the conductive sleeve 9 and the connector main body 8, and is a member made of metal or the like having conductivity and a spring. The shield connecting spring 14 has, for example, a wave washer shape shown in FIG. 8, a chrysanthemum washer (also referred to as a tooth thrust washer) shape shown in FIG. 9, or a split spring washer shape shown in FIG.

The tightening holder 13 of FIG. 1 is made of a metal such as a steel material or a hard material such as a synthetic resin, and the outer peripheral surface of the front portion is a male screw portion 23. The tightening holder 13 is screwed into the female screw portion 17 of the connector main body 8 to press the electric wire waterproof packing 11 and is abutted against the waterproof material holder 10, and the conductive sleeve 9 is attached to the connector main body 8 by the waterproof material holder 10. It is in a pressed state against the diameter changing surface 8ad on the front side.

The connection work by the shielded electric wire connector 1 having the above configuration will be described. The tightening holder 13, the electric wire waterproof packing 11, the waterproof material holder 10, the internal waterproof packing 12, the conductive sleeve 9, and the shield connecting spring 14 are sequentially inserted into the shielded electric wire 2. After that, as shown in FIG. 5, the insulating coating 4, the shield 5, and the outer skin 6 of the shielded electric wire 2 are peeled off, the shield 5 is folded back, and the conductive sleeve 9 is fixed to the outer periphery thereof as described above. After that, the shielded electric wire 2 is passed through the connector body 8 (state in FIG. 3), and the tightening holder 13 is tightened as shown in FIG. After that, the terminal 7 is attached.

According to the shielded electric wire connector 1 having this configuration, the conductive sleeve 9 that covers the shield folded-back portion 5a of the shielded electric wire 2 and is in a conductive state with the shield 5 is fitted on the inner circumference of the connector main body 8. The conductive sleeve 9 is pushed forward by the waterproof material holder 10 by tightening the tightening holder 10, and is pressed against the stepped diameter changing surface 8ad of the connector main body 8. At the pressing point, the shield 5 of the shielded electric wire 2 and the connector main body 8 are electrically connected, and the grounding circuit is connected. Since the contact is made in the axially pressed state in this way, the electric wire connection strength in the vehicle is ensured, and the connection of the grounding circuit of the shielded electric wire 2 can be reliably maintained even if vibration is applied.
Since the shield connection spring 14 is interposed at this connection location, the connection is secured even if there is some rattling in tightening the tightening holder 13 or some looseness as a result of aging.

Further, the conductive sleeve 9 is pressed from the entire circumference of the outer peripheral surface to reduce the diameter of the entire surface, and then a recessed portion 19 is formed by spot caulking to form a shield of the shielded electric wire 2. It is made to bite into the folded-back portion 5a. Therefore, the fixing strength of the conductive sleeve 9 to the shielded electric wire 2 is improved, and the electrical contact between the shield 5 and the conductive sleeve 9 is more reliably maintained.

For waterproofing, the internal waterproof packing 12 is sandwiched between the connector body 8 and the waterproof material holder 10, and the tightening holder 13 is attached with the electric wire waterproof packing 11 sandwiched between the waterproof material holder 10 and the tightening holder 13. There is. Therefore, waterproofness can be obtained between the shielded electric wire 2 and the connector main body 2. In this case, the electric wire waterproof packing 11 is shielded because it is pushed by the tightening holder 13 with a part of the inner annular recess 21 formed from the inner peripheral surface to the rear side surface of the waterproof material holder 10. The electric wire waterproof packing 11 is deformed so as to bite into the outer skin 6 of the electric wire 2, and the pressing pressure on the contact surface is strong, so that excellent waterproofness can be obtained. Since the inner peripheral surface of the inner annular recess 21 is a tapered surface whose bottom side is reduced in diameter, the electric wire waterproof packing 11 is elastically deformed to a reduced diameter state by being pushed in the axial direction by the tightening holder 13. Therefore, the outer circumference of the shielded electric wire 2 is in stronger contact with the outer circumference, and the waterproof property is further improved. Also between the waterproof material holder 10 and the connector main body 8, since the internal waterproof packing 12 is arranged in the outer annular recess 22 formed from the outer peripheral surface to the front side surface of the waterproof material holder 10, it is for internal waterproofing. The packing 12 is strongly pressed against the inner surface of the connector body 8 to ensure reliable waterproofness.

In this way, the connection between the shield 5 of the shielded electric wire 2 and the grounding circuit is ensured, and reliable waterproofness is obtained, so that no other complicated configuration for ensuring the connection and sealing is required. , It has a simple structure and can be manufactured at low cost. Further, the tightening work of the tightening holder 13 can simultaneously secure the conductivity of the conductive sleeve 9 and the waterproofness inside the connector body 8, and is excellent in workability.

Since the tightening holder 13 is tightened by screwing the male threaded portion 23 on the outer circumference into the female threaded portion 17 of the connector body 8, strong pressing of the conductive sleeve 9 and the packings 11 and 12 can be obtained with a simple configuration. Also, the work to obtain the pressing force is simple as it only needs to be tightened by rotation.

As for the mounting form of the tightening holder 13 to the connector main body 8, in the above embodiment, the male screw portion 23 on the outer circumference of the tightening holder 13 is used, but it is conductive together with the electric wire waterproof packing 11 and the waterproof material holder 10. Any form may be used as long as the sleeve 9 can be pressed, and various other configurations can be adopted. For example, although not shown, the front portion of the tightening holder 13 is double-cylindrical, and the female screw portion provided on the inner circumference of the outer tubular portion is screwed into the male screw portion provided on the outer periphery of the connector main body 8. The waterproof material holder 10 may be pressed against the connector body 8 or the tightening holder 13 may be attached to the connector body 8 by crimping the connector body 8 or the tightening holder 13.
