Anti-drop structure of engine wire harness connector

Abstract

The utility model relates to an anti-drop structure of an engine wire harness connector, which comprises a sensor and a wire harness connector, a limiting bump is formed on a joint of the sensor, the wire harness connector is sleeved on the joint of the sensor, a locking barrier strip and an elastic handle are arranged in the wire harness connector, connecting arms are formed at two ends of the locking barrier strip, and the elastic handle is sleeved on the elastic handle. The connecting arm is connected with the elastic handle, the elastic handle is manually pressed to drive the locking barrier strip to move, and the locking barrier strip is buckled on a limiting convex block of the sensor; an anti-releasing piece is inserted and buckled in the wire harness connector, the anti-releasing piece comprises a U-shaped rear framework, an elastic spring bolt is formed in the middle of the rear framework, the elastic spring bolt is inserted between connecting arms of the wire harness connector, a downward clamping hook is formed at the tail end of the elastic spring bolt, and the clamping hook is buckled on the locking barrier strip. According to the anti-falling structure, the problems of separation and falling of the engine wire harness connector can be effectively avoided, and the safety and the reliability of an engine wire harness assembly and even a whole electric control system can be improved.
