Description

Vehicle package connector {WIRING PACKAGE CONNECTOR OF VEHICLE}

The present invention relates to a vehicle package connector, and more particularly, by assembling a plurality of wire connectors for guiding the flow of different currents in one female housing and then connecting the corresponding male housing, connectors for each current (voltage) have been previously developed. The present invention relates to a vehicle package connector capable of realizing miniaturization and cost reduction of wiring compared to those provided, and improving the corrosion resistance of the shielding area inside the connector by improving the waterproof ability between each wire connection part and the female housing.

A connector is an electrical connection to transmit signals and power to or between parts.

When power or a signal is transmitted through a connector, it is important to prevent electrical interference. In particular, a connector used at a high voltage should not cause electrical interference.

Recently, with the development of electric vehicles or hybrid vehicles, there are many connectors for high voltage among connectors used in vehicles. High-voltage connectors used in high voltage use a shield shell for shielding between the inner housing and the outer housing. The shield shell is generally installed to surround the outer surface of the inner housing, and for shielding electromagnetic waves, a conductive mesh network of wires and electrical connected to

In particular, among the shield shells, there are some that are coupled to the inner housing at the top and bottom to surround the inner housing, and separate support rings and crimp rings are used to couple these two shield shells with wires, particularly mesh networks.
