Wiring terminal connecting structure and processing method thereof

The invention relates to a wiring terminal connecting structure and a processing method thereof, belongs to the technical field of electric fittings, and solves the problems that an existing wiring terminal is poor in reliability, complex in processing and large in cable diameter at the joint. A wiring terminal connecting structure comprises a wiring terminal, a wiring terminal heat-shrinkable sleeve, a wire shielding layer inner protection heat-shrinkable sleeve, a wire shielding layer and a shielding heat-shrinkable sleeve. A wire core wire of a wire to be connected sequentially comprises awire insulating layer, a wire shielding layer inner protection heat-shrinkable sleeve and a wire shielding layer from inside to outside. The wiring terminal heat-shrinkable sleeve is sleeved outside the wiring terminal and envelops the wire insulating layers at the two ends of the wiring terminal; and the shielding heat-shrinkable sleeve is sleeved outside the wiring terminal heat-shrinkable sleeve and envelops the sleevi
