[0002] At present, pin header connectors are widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Their role is to act as a bridge between blocked or isolated circuits within the circuit, and to undertake the task of current or signal transmission. Pin header connectors are usually used in conjunction with female header connectors to form a board-to-board connection; or used in conjunction with electronic wiring harness terminals to form a board-to-wire connection; they can also be used independently for board-to-board connection. However, since the pins of some pin header connectors are relatively long, it is easy to cause the pins to deform during use, which affects the normal use of the pin header connector.
