[0001] SHIELD SHELL STRUCTURE FOR CONNECTOR [0002]

Embodiments of the present invention relate to a shield shell structure of a connector, and more particularly, to a shield shell structure of a connector having a structure capable of providing a shield contact with a coated vehicle panel by bolt tightening of a simple connector.

A connector is a medium that maintains electrical performance while firmly connecting electrical parts with each other. It serves as a bridge between electrical wires in various technical fields such as automobiles.

Specifically, the connector is a component formed in a wire harness in an automobile part, and is provided so as to be able to smoothly supply current without loss by connecting a terminal electrically connected to a wire and a housing for protecting the terminal.

In recent years, in many technical fields such as automobiles, electric components are increasingly used, and high voltage connectors are widely used so that a plurality of wires can be connected at a time. Since such a high voltage connector generates a considerable amount of electromagnetic waves due to a high voltage, electromagnetic wave shielding performance is required. In the method of shielding electromagnetic waves, there is a separate shielding method in which a shield is provided on a separate electric wire, and a method in which a shielding is performed using a braid that surrounds various electric wires.

Preferably, in the case of a high-voltage connector, a shield case must be provided on the outer surface of the connector for grounding, and the wires must be grounded. To this end, a plurality of wires are electrically connected to the shield case to perform grounding. If any one of the wires is not electrically connected to the shield case, the wire may not be properly grounded.

For example, as a shield contact method between a vehicle panel and a connector according to the prior art, a shield contact method using a spring tension of a shield shell is most commonly used. This was possible when the vehicle's panel was a die-casting or metal panel.

However, when the coating is applied to the panel of the vehicle, the coating itself acts as an insulator, and the shield contact with the connector is not achieved.

A prior art related to the present invention is Korean Patent Registration No. 10-0774654, which discloses a shield type connector.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a shield shell structure of a connector capable of a shield contact with a vehicle-coated vehicle panel by bolt fastening of a simple connector.

The problems to be solved by the present invention are not limited to the above-mentioned problems, and other problems not mentioned here can be understood by those skilled in the art from the following description.

According to an embodiment of the present invention, there is provided a shield shell structure of a vehicle panel having a coating portion and a connector capable of a shield contact, the shield shell structure comprising: a shield shell body; And a plurality of acute projections protruding in a sharp shape from the shield shell main body to face the coating portion, wherein the plurality of acute projections are disposed adjacent to a bolt for fastening between the connector and the vehicle panel And the plurality of acute projections penetrate through the coating portion in the thickness direction only by fastening the bolts, thereby forming a shield contact.

At this time, the shield shell body is provided with a fastening hole to which the bolt is fastened, and the plurality of sharpened protrusions can be disposed along the circumferential direction around the fastening hole.

Preferably, each of the plurality of acute projections may be spaced apart from the fastening hole by a predetermined distance.

Further, preferably, each of the plurality of acute projections may be spaced apart from each other with a certain central angle along the circumferential direction.

The plurality of acute projections may protrude from the shield shell body so as to face the coating portion at a plurality of inclined angles.

Preferably, the plurality of acute projections include: a first protrusion having a first inclination angle from the shield shell body and protruding toward the coating portion; And a second protrusion having a second inclination angle larger than the first inclination angle from the tip of the first protrusion and protruding toward the coating portion.

According to the shield shell structure of the connector of the present invention, there is an advantage that a shield contact with a coated vehicle panel can be achieved only by a bolt fastening operation of a simple connector.

According to this, when the coating portion is formed on the panel of the vehicle, the coating portion itself serves as an insulator, and the problem of the shield contact with the connector can not be solved. Specifically, a plurality of protrusions protruding sharply toward the coating portion of the vehicle panel are formed on the facing surface of the shield shell, so that the shield contact can be made possible only by bolt fastening of the connector.

The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

A connector is a medium that maintains electrical performance while firmly connecting electrical parts with each other. It serves as a bridge between electrical wires in various technical fields such as automobiles.

In recent years, in many technical fields such as automobiles, electric parts using electric power are increasing, and high-voltage connectors are widely used so that a plurality of electric wires can be connected at a time. Since such a high voltage connector generates a considerable amount of electromagnetic waves due to a high voltage, electromagnetic wave shielding performance is required. There are two methods of shielding electromagnetic waves: the individual shielding method in which a shield is provided on a separate electric wire and the method of collectively shielding by using a braid that surrounds various electric wires.

As a shield contact method between a vehicle panel and a connector according to the related art, a shield contact method using a spring tension of a shield shell is most commonly used.
