Description

connector assembly {CONNECTOR ASSEMBLY}

The following description relates to a connector assembly, and specifically, to a connector assembly including a shield to be assembled.

A connector is a kind of part that selectively connects or blocks an electrical connection. BACKGROUND ART In general, many electric parts such as electronic parts or sensors are installed in automobiles, and these electric parts are electrically connected to other electric parts or power sources through cables and connectors. In the case of a cable or connector through which a high voltage and/or high current that can be electric shock to a person flows, a shield for preventing electric shock or noise may be provided.

For example, when two electrical components are connected to each other through a connector, when electromagnetic waves generated from the electrical components leak through the connector, they may interfere with nearby electrical components and cause a malfunction.
