CONNECTOR

摘要

A connector comprises a terminal and a layered circuit substrate. The layered circuit substrate connects to an end of the terminal, and comprises a PTC material layer, a first electrode layer forming an upper layer of the layered circuit substrate, and a second electrode layer forming a lower surface of the layered circuit substrate. The PTC material layer is disposed between the first and second electrode layers. The first and second electrode layers comprise first and second electrode pads which connect to a power supply, and the PTC material layer electrically connects to the first and second electrode pads to form an electrically conductive path in which the PTC material layer serves as a PTC resistor in series connection between the first and second electrode pads. When an over-current or over-temperature event occurs in the electrically conductive path, the PTC resistor will trip to a high resistance state.
