Described puncture type pin is the foil perpendicular to terminal, and the front end of puncture type pin forms at least one spiny body that punctures.

Described two puncture body and are one on the other and arrange, and two tips that puncture body are staggered before and after being.

Offer on the described winding displacement plug that two rows are used to accommodate and the fixing wire casing of heart yearn, offer the accepting groove of two rows perpendicular to wire casing on the front end face, each accepting groove communicates with corresponding wire casing respectively.

The left and right sides of described glue core is respectively arranged with the pin of buckleing of barb shape, and the left and right sides of winding displacement plug is respectively arranged with step-like button bit, and the winding displacement plug is by the buckle rear end that the cooperating of pin snap onto glue core of the button bit on it with the glue core.

The beneficial effects of the utility model: each heart yearn of the present utility model is aligned to two rows, and the end of heart yearn bending up or down respectively forms a bending part, each tail portion of terminal is provided with and punctures the puncture type pin that direction is parallel to terminal, puncture type pin edge when the winding displacement plug is fixed on the glue core on the terminal directly penetrates in the bending part of corresponding heart yearn perpendicular to the direction of the front end face of winding displacement plug, the utility model is finished the electric connection of heart yearn and terminal by the mode of puncturing, do not need welding processing, reduce production costs, minimizing is to the pollution of environment, and effectively solves the problem that the little USB connector of width can't be used the puncture type structure.
