CONNECTOR SYSTEM AND ASSEMBLY HAVING INTEGRATED PROTECTION CIRCUITRY

摘要

A connector assembly (10) with integrated protection circuitry including a plug subassemby (12) and a sensor connector subassembly (14).The sensor connector subassembly is selectively connectable to the plug subassembly. A circuit board (46) is secured within the sensor connector subassembly. The circuit board includes at least one positive temperature coefficient (PTC) (90,92) device electrically connected between an activation switch (80) and a load (84).The circuit board includes a circuit (44) to protect against at least one of over- voltage or over- current to the load, detect a fault condition of the load, and determine whether the plug subassembly is connected to the sensor connector subassembly.
