[0035] The front-rear direction in the embodiment is the direction in which the plug is inserted into the socket.
[0036] With reference to Figures 1-5 Before assembly, the signal core 3 is plastic-wrapped on the signal pin 4, so that the signal core 3 and the signal pin 4 are connected into an integrated whole, the signal core 3 forms the second clamping groove 34 in the plastic-wrapping process, and the second clamping groove 34 and the second clamping buckle 41 are seamlessly connected; after the signal pin 4 and the signal core 3 are plastic-wrapped into an integrated whole, the combination formed by the signal pin 4 and the signal core 3 is inserted from the rear end of the first accommodating cavity 13 until the first clamping buckle 33 of the signal core 3 is clamped into the first clamping groove 14, at this time, the front end of the signal pin 4 passes out from the through hole to the front end to realize signal interlocking with the signal connection end of the plug. In the use process, due to the double anti-retreat of the first clamping buckle 33 and the first clamping groove 14 and the second clamping buckle 41 and the second clamping groove 34, the signal terminal can be stably connected with the socket ground connection end, thereby ensuring the connection quality of the plug and the socket.
