Detailed Description

The following detailed description of the present invention is made with reference to the accompanying drawings. As shown in fig. 1.

Example 1: the utility model provides a female terminal of torsional type, its includes an annular grafting section of thick bamboo 2, and the front end of a grafting section of thick bamboo 2 is equipped with shell fragment structure 1, and the rear end of a grafting section of thick bamboo 2 is equipped with riveting portion 3, shell fragment structure 1 includes multi-disc shell fragment 11, is equipped with the clearance between the shell fragment 11, and the middle part incurving of shell fragment 11, the both ends of shell fragment 11 dislocation set on the axial direction of a grafting section of thick bamboo 2.

Compared with the prior art, the technical scheme has the advantages that one end of the elastic sheet structure 1 is rotated relative to the other end, so that the two ends of the elastic sheet 11 are staggered in the axial direction, when the signal needle is inserted into and abutted against the elastic sheet 11, the elastic sheet 11 is in a twisted state, the signal needle is in line contact with the elastic sheet 11, and the contact area between the elastic sheet 11 and the signal needle is effectively increased.

Furthermore, the middle part of the insertion tube 2 is provided with a plurality of middle spring pieces 22, one end of each middle spring piece 22 close to the spring piece structure 1 is connected with the insertion tube 2, and one end of each middle spring piece 22 far away from the insertion tube 2 is bent outwards.

When in molding, a rubber shell is injected outside the torsional female terminal; when in use, the signal pin is inserted into the elastic sheet structure 1 and has a larger friction force to the elastic sheet structure 1; make shell fragment structure 1 and torsion-type female terminal have the power of a relative gluey shell, take place to break away from for preventing torsion-type female terminal and gluey shell, this technical scheme has set up a plurality of middle shell fragments 22 at the middle part of a grafting section of thick bamboo 2, and the one end of middle shell fragment 22 outside bending will hinder torsion-type female terminal to removing to riveting portion 3 direction.
