The cooperation chamber 2 is fixed the back with the hole seat cooperation, mainly with the contact pin cooperation on corresponding the connector, insert the needle and stretch into to cooperation chamber 2 in, the contact pin offsets with the shell fragment that cooperates in the chamber 2 to realize the electric connection effect. The matching cavity 2 is internally provided with an elastic sheet 5, a first bubble point 21, a second bubble point 22, a supporting part 23 and a first limiting part 24.

The shell fragment 5 is the multistage setting of bending, and 5 front ends of shell fragments are located the open position of

cooperation chamber

2, and 5 front ends of shell fragment are connected with the one end of supporting

part

23, and 5 front ends of shell fragment are the cambered surface setting, have played the effect of a cambered surface direction, and the contact pin of being convenient for moves towards the position of first uplift 51.

The middle end of the elastic sheet 5 is provided with a first raised part 51, the first raised part 51 is raised towards the top surface of the matching cavity 2, in the embodiment, the center of the top surface of the first raised part 51 is provided with a first reinforcing rib 511, and the arrangement of the first reinforcing rib 511 further improves the contact area between the elastic sheet 5 and the pin. The size of the first reinforcing rib 511 is irrelevant to the protection point, and a person skilled in the art can obtain an optimal scheme through multiple tests according to actual requirements.

The tail end of the elastic sheet 5 is provided with a second bulge 52, the second bulge 52 is bulged towards the bottom surface of the matching cavity 2, and the second bulge 52 is abutted against the second bubble point 22.

The first bubble point 21 is located on the top surface of the inner wall of the matching chamber 2, i.e. the first bubble point 21 is located above the first bump 51, in this embodiment, the first bubble point 21 is preferably in a long strip shape. Under initial condition, there is certain clearance between first bubble point 21 and the first bulge 51, the back is stretched into to the contact pin of being convenient for first bulge 51 pushes down for area of contact between contact pin and the first bulge 51 is bigger, and electrical connection is more stable.

Second bubble point 22 is located the cooperation intracavity 2 inner wall bottom surface, specifically is located on the below of second uplift portion 52, and second uplift portion 52 offsets with second bubble point 22, and when the contact pin inserted the back, 5 afterbody of shell fragment and the contact of second bubble point 22 for the terminal wholly has higher contact reliability. Here, the second bubble point 22 abuts against the second stopper 3.

Supporting part 23 is located the bottom surface of cooperation chamber 2 inner wall, and here specifically means the front end position that is close to cooperation chamber 2, and supporting part 23 is the level setting, and supporting part 23 one end is connected with 5 front ends of shell fragment, forms a triangle-shaped structure to make 5 holistic stability of shell fragment further improve, supporting part 23 has played the support and has reset the effect. The other end of the support portion 23 is connected to the first stopper portion 24, where the first stopper portion 24 is vertically connected to the support portion 23, and the first stopper portion 24 extends toward the first bump portion 51. The arrangement of the first limiting portion 24 is used for preventing the contact pin from being obliquely inserted in the matching process of the contact pin and the terminal, when the contact pin is obliquely inserted, the contact pin is abutted to the first limiting portion 24, the contact pin cannot be further inserted, and therefore the protection effect is achieved.
