Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield processing section formed by, for example, shielding a wiring in an automobile.

[0002]

2. Description of the Related Art In recent years, a large number of electronic devices have been used in automobiles. In order to prevent noise from entering such electronic devices, shielded wires are partially provided in electric wires in the automobile. It is used.

As described above, there is no problem in the case where the shielded wire is used from the beginning, but there is a case where it is desired to shield the portion where the normal wire, that is, the unshielded wire is used at the beginning.

In such a case, conventionally, a long drain wire having one end grounded is passed along an unshielded electric wire,
A shield body made of aluminum foil or the like is wound around the drain wire while electrically contacting the drain wire and covering the unshielded electric wire, thereby shielding the unshielded electric wire.

[0005]

However, as in the prior art, a long drain wire extends along an unshielded wire, and the drain wire and the unshielded wire are brought into electrical contact with the drain wire. If the structure is to cover and wrap the shield, the long drain wire is flexible, so when wrapping the shield, the shield must be wrapped while holding down the drain wire, which is troublesome. There was a problem. In addition, there is a problem that the shield of the connector portion to which the unshielded electric wire is connected is insufficient.

[0006]

SUMMARY OF THE INVENTION The present invention provides a shield processing unit which solves the above-mentioned problems, and the structure thereof is as follows.
Insert the terminal portion of the drain terminal having a terminal portion inserted into the connector and a shield connection piece located outside the connector when the terminal portion is inserted into the connector into the connector, and insert into the connector Connect the ground terminal to the grounded terminal part, and connect the shield connecting piece located outside the connector to
A shield body wound around the outer periphery of the connector and the outer periphery of the electric wire connected to the connector is electrically connected.

By connecting the ground terminal to the terminal of the drain terminal and electrically connecting the shield to the shield connecting piece of the drain terminal, the shield can be easily grounded. Further, since the shield is wound around the outer periphery of the connector and the outer periphery of the electric wire connected to the connector, the connector and the electric wire connected to the connector can be easily shielded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view of a drain terminal used in the present invention. The drain terminal 10 is made of a copper alloy or the like, and includes a male terminal portion 11 and a U-shaped shield connection piece 12 integrally formed with the terminal portion 11 behind the terminal portion 11. . The male terminal 11 is inserted and locked in the connector 20, and the shield connecting piece 12 is connected to the terminal 10.
The upper surface portion 12 </ b> A is configured to be exposed to the outer surface of the connector 10 when is inserted and locked in the connector 20.

Therefore, as shown in FIG. 2, when the terminal portion 11 is inserted and locked in the connector 20, the upper surface portion 12A of the shield connecting piece 12 is exposed to the outer surface of the connector 20 as shown in FIG. Becomes

The connector 20 according to the embodiment has four terminal insertion holes, and a terminal 40 to which an unshielded electric wire 30 is connected is provided in each of the remaining terminal insertion holes 21 into which the drain terminal 10 is not inserted. It is inserted and locked.

As shown in FIG. 3, a shield 50 made of a conductor such as aluminum foil is electrically connected to the upper surface 12A of the shield connection piece 12 exposed on the outer surface of the connector 20 of the drain terminal 10. You.

As shown in FIG. 4, the shield 50 is wound around the outer periphery of the connector 20 and the outer periphery of the electric wire 30 connected to the connector 20.

Although not shown, the terminal portion 11 of the drain terminal 10 inserted and locked in the connector 20 is inserted and locked in the mating connector when the connector 20 is fitted to the mating connector. And a female ground terminal connected to the ground circuit.

As a result, the shield body 50 wound around the outer periphery of the connector 20 and the outer periphery of the electric wire 30 connected to the connector 20 is grounded. Therefore, the connector 20 and the electric wire 30 connected to the connector 20 can be easily shielded.

In the above embodiment, the terminal portion of the drain terminal is of a male type, but may be of a female type. The number of terminal insertion holes of the connector is not limited to four, but may be two or more. Further, the shape of the shield connecting piece of the drain terminal is not particularly limited as long as the shield can be electrically connected. Further, a braided conductor or the like may be used as the shield body. Further, it is preferable to wrap a protective tape or the like around the outer periphery of the shield body.

[0016]

As described above, the shield processing portion is a drain terminal having a terminal portion inserted into the connector and a shield connection piece located outside the connector when the terminal portion is inserted into the connector. The terminal portion is inserted into the connector, the ground terminal is connected to the terminal portion inserted into the connector, and the outer periphery of the connector and the outer periphery of the electric wire connected to the connector are connected to the shield connecting piece located outside the connector. Since the shield body wound around the shield body is electrically connected, the shield body can be easily grounded via the drain terminal. Further, since the shield body can be easily wound around the outer periphery of the connector and the outer periphery of the electric wire connected to the connector, the winding operation is easy and the connector can be shielded easily.
