[0002] Electrical connectors are a common electronic component, widely used in aviation, electronics, machinery and other industries. Electrical connectors play a role in separation and connection at the electrical terminals, and can be used to facilitate installation and plugging and complete the electrical connection and signal transmission between the various circuits of electronic equipment. Electrical connectors are generally composed of a housing, an insulator, a contact body and accessories. The transmission of energy and signals is completed by the insertion of the pin and the pin. The correct connection of the circuit relies on the isolation effect of the insulator to isolate the contact body and ensure the stability of the circuit. However, when the signal transmission signal needs to be interconnected through the printed circuit board, the traditional circular pinhole connector cannot be connected with it.
