Description of the Related Art In connection between electronic devices, a shield wire is sometimes used as a measure against electromagnetic interference, and an inner conductor is shielded by grounding a metal net wire (shield braid) covering the outside. Shielded from the electric field. When a connector is interposed in this shielded wire, the connector is covered with a conductive cover (shield cover). For example, as shown in FIG. 6, the end of the shield wire 1 is stripped of an insulating coating (sheath) 3 with an appropriate length, and the exposed shield braid 5 is folded back to the sheath 3 side, while the insulating core wire is (Hereinafter, simply referred to as “core wire”) 7 is connected to the terminal 11 of the connector 9. And the shield cover 13a
After the connector 9 is set on the shield braid 5, the shield braid 5 is fixed to the shield cover 13 a side with the screw 17 using the fastener 15, and is covered with the shield cover 13 b and fixed with the screw 19.

ることを目的とする。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 connected. , The screws 19 are used to secure the shield covers 13a and 13b, so that a total of two sets of shield members are used, and the number of parts is large.
There was a problem that the workability of assembly 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 the vibration of the vehicle or the like. In case, shield braid 5
A force is applied only to the fixing portion between the metal member and the stopper 15, and the shield braid 5 is likely to be displaced, and the noise absorbed by the shield covers 13a and 13b from the outside is transmitted only to the shield braid 5 and grounded. However, there is a problem that the grounding cannot be directly performed, and the shielding 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 (see FIG. 6).
No particular consideration was given to the waterproofness of the connector 9 and the waterproofness of the connector 9 alone had to be relied on. Conventionally, as shown in FIG. 7, after the shield braid 5 is crimped with the metal shell 23 and then the shield wire 1 and the metal shell 2 are formed by insert molding, as shown in FIG.
3 was molded to have a waterproof structure,
Insert molding has caused a cost increase. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables a shield braid to be connected by a simple operation with a reduced number of parts, and a shield effect to be improved by being directly groundable to a body, and furthermore, a shield cover Provide a shield terminal treatment structure that can also ensure the waterproofness of
It is intended to improve workability, electromagnetic shielding properties, and waterproofness.

とができる。As described above in detail, according to the shield terminal treatment structure of the present invention, the shield of the connector and the connection between the conductive cover and the shield braid can be achieved with a small number of parts, so that the assembly is easy. Can be attached and workability can be improved. The noise absorbed by the conductive cover can be directly grounded to another member via the fixing means, so that the shielding effect can be significantly improved. Also, if the shield braid portion sandwiched between the wire holding elastic pieces is sandwiched from a further different outer circumferential direction by the first bent piece for preventing wire removal and the second bent piece for preventing wire removal, the shield braid is further improved. It can be securely held. Furthermore, by providing a packing in the wire insertion notch, it is possible to ensure the waterproofness of the conductive cover when the shield wire is inserted. In addition, since the conductive cover does not specify the shape of the connector, an existing connector can be used, a new connector need not be manufactured, and an increase in cost can be prevented.
