Description

Bundle Shielded Connector

The present invention relates to a collectively shielded connector, and more particularly, to a collectively shielded connector that shields electromagnetic waves of a high voltage wire, but collectively shields the entire wire connected to the connector.

Connectors are used in various technical fields such as automobiles as a medium to securely connect electrical parts and maintain electrical performance. The connector is used between the driving unit and the wire connected to the unit, and has a built-in terminal insert for connection, a bus bar, and the like. In recent years, due to the advancement of various technical fields such as automobiles, electronic components are increasing, and therefore, high voltage connectors are widely used so that a plurality of wires can be connected to a circuit at once.

The high voltage connector generates a considerable amount of electromagnetic waves in response to processing the high voltage, and thus electromagnetic wave shielding performance is required. This is because if the shielding is not performed, the malfunction of other electrical equipment in the vicinity may be caused by the leaked electromagnetic waves. As a method of shielding electromagnetic waves, there are an individual shielding method in which a shield is built into individual wires, and a method of collectively shielding by using a braided wire that wraps several wires at the same time.

In the case of individual shielding, since the shielding plate is located inside the connector main end (waterproof area) and sealing is provided between the outer circumference of the wire and the connector, the shielding plate is located in the waterproof area. However, in the case of collective shielding, the shielding plate is disposed outside the main end (waterproof area) inside the connector, and the shielding plate is located in the non-waterproof area due to the connection of the braided wire to the shielding plate.
