Ignition cable interface anti-disengagement structure and assembly method

The invention belongs to the technical field of engine electric ignition, and particularly relates to an ignition cable interface anti-disengaging structure and an assembling method, and the ignition cable interface anti-disengaging structure is composed of a lining, a nut, a spring, a high-voltage ignition wire, a check ring, a rubber gasket, an insulation pipe and an insertion hole. The high-voltage ignition wire sequentially penetrates through the lining, the spring, the check ring, the rubber gasket and the insulation pipe, the tail end of the insulation pipe is screwed into a concave groove in the lining through threads, then the high-voltage ignition wire and the insertion hole are connected in a pressing mode, finally the insertion hole is screwed into the insulation pipe, and assembly of the anti-disengaging interface of the ignition cable is completed. The anti-separation interface design is formed through mutual limiting of the interface parts of the ignition cable, the problem that assembly is diff
