Description

High Voltage Connector The present invention relates to a high-voltage connector, and more specifically, to a high-voltage connector capable of uniformly exhibiting shielding performance by inserting flat wiring into an inner housing so as to be connectable, while simultaneously making contact with a shield case so as to be groundable. Generally, connectors are installed in wire harnesses and/or electrical components to supply power or transmit signals. These connectors are classified into low-voltage and high-voltage types depending on the application and function of the electrical components, and the use of high-voltage connectors is increasing with the development of electric vehicles and the like. A cable to which a high current is applied is installed in a high-voltage connector, and at this time, electromagnetic waves caused by the high current are generated around the cable. To block such electrical interference, such as electromagnetic waves, a shield shell is provided in the high-voltage connector. Meanwhile, an electromagnetic shielding core wire is used in the high-voltage connector, a shielding mesh is provided between the inner insulation layer and the outer insulation layer of the core wire, and the shielding mesh is compressed from the shield shell by a ring-shaped shield clip. In a conventional high-voltage connector, the shield shell is positioned to accommodate the perimeter of the shield mesh while the shield mesh provided on the core wire is folded to cover the outer insulation layer of the core wire, and then the shield shell is compressed through a shield clip. However, such shield clips have the problem of reducing assembly workability because they get caught on the shielding mesh during the process of moving the shield shell to a position where it can be crimped while inserted into the core wire. Furthermore, if twisting occurs in the core wire while the shield shell is crimped, the clip detaches from the shield shell due to low fixing force, causing the crimping to be released. Therefore, there is a need to improve this. A related background technology is Korean Published Patent Application No. 10-2021-0170196 (Published June 28, 2021, Title: Connector).
