Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield terminal treatment structure for connecting a shield braid of a shield wire to a conductive cover of a connector.

[0002]

2. Description of the Related Art When connecting electronic devices to each other, a shielded wire is sometimes used as a countermeasure against electromagnetic interference. By grounding a metal net electric wire (shield braid) that covers the outside, the inner conductor is connected to the outside. It is shielded from the electric field. When the connector is interposed in the shield wire, the connector is covered with a conductive cover (shield cover). For example, as shown in FIG. 11, at the end of the shielded wire 1, the insulation coating (sheath) 3 is peeled off with an appropriate length, and the exposed shield braid 5 is folded back to the sheath 3 side while the core wire 7 is formed. Is connected to the terminal 11 of the connector 9. Then, after the connector 9 is set on the shield cover 13a, the shield braid 5 is attached to the shield cover 1 by using the fasteners 15.
It is fixed with a screw 17 on the 3a side, and is fixed with a screw 19 by covering the shield cover 13b. Although illustration is omitted, the mating connector connected to the connector 9 has the same structure. Therefore, in the portion where the connector is interposed, the shield covers 13a and 13b, the fastener 15,
Two sets of screws 17 and 19 will be used.

By processing the end of the shielded wire 1 with such a structure, the shield braid 5 is shielded by the shield cover 13.
a shield cover 13 that is connected to a and covers the connector 9
By grounding a and 13b, it was possible to prevent the electromagnetic interference even at the connector coupling portion.

[0004]

However, in the conventional shield terminal treatment structure, the shield braid 5 is fixed by the fastener 15 by using the screw 17 in each of the connector 9 and the mating connector to be joined, and further, Since they were fixed by the shield covers 13a and 13b by using the screws 19, a total of two sets of shield members are used, and the number of parts is large.
There was a problem that assembly workability was poor. Further, since the connector 9 is not fixed in the shield covers 13a and 13b and the shield covers 13a and 13b are not fixed to the body of the electronic device or the like, a force in the pulling direction acts on the shield wire 1 due to vibration of the vehicle or the like. If the shield braid 5
The force acts only on the fixed portion between the fixing member 15 and the stopper 15, and the shield braid 5 at the fixed portion is likely to be displaced, and noise absorbed from the outside by the shield covers 13a and 13b is transmitted only through the shield braid 5 and is grounded. Therefore, there is a problem in that the ground cannot be directly grounded to the body and the shield effect is reduced. Further, in the above-described shield terminal processing structure, the shield wire through holes 21 of the shield covers 13a and 13b are provided.
The waterproofness (see FIG. 11) is not particularly considered, and the waterproofness of only the connector 9 has to be relied upon. In order to simultaneously prevent electromagnetic interference and achieve waterproofness, conventionally, as shown in FIG. 12, after caulking the shield braid 5 with the metal shell 23, the shield wire 1 and the metal shell 23 are molded by insert molding, Some had a waterproof structure, but insert molding was a factor in increasing costs. The present invention has been made in view of the above situation,
A shield terminal treatment structure that can reduce the number of parts and connect the shield braid with easy work, and enhance the shield effect by directly grounding to the body, and also ensure the waterproofness of the shield cover It is intended to improve the workability, the electromagnetic shielding property, and the waterproof property.
