Wiring harness connection structure of relay

The utility model relates to the technical field of electrical equipment, and discloses a wiring harness connecting structure of a relay, which comprises the relay, wiring ports are arranged at two ends of the relay, a fixing port is arranged on the relay, a sliding rail is fixedly arranged on the outer wall of the relay, and the sliding rail is connected with the wiring ports. According to the wiring harness connecting structure of the relay, a wiring harness is placed in a wiring port, the clamping plates are extruded to rotate towards the interior of the wiring port in the wiring harness entering process, the wiring harness is clamped in the wiring port, and the clamping plates are clamped in the wiring port. The clamping plate is driven to rotate towards the outside of the wiring port by matching with the tension of the torsional spring, so that the wiring harness is clamped, pre-fixed and prevented from being separated during fixing, the sliding plate extrudes the sliding rod in the sliding process, the
