Abstract
The utility model provides a socket. The socket solves the problems that the contact between a contact pad of the existing socket and a plug is poor; temperature rise is high; a clamping force is unstable; insertion and extraction forces are large and unstable; the contact pad has large wear amount and is easy to deformation; and the stability of the socket is affected. The socket comprises a box body, the contact pads, surface contact springs and limiting mechanisms. Each surface contact spring comprises a contact surface which contacts the outer side of each contact pad, an upper deformation surface which is connected with the upper end of the contact surface and a lower deformation surface which is connected with the lower end of the contact surface. The free end of each upper deformation surface is folded back and bent with the back to each contact pad. The free end of each lower deformation surface is folded back and bent with the back to each contact pad. The upper deformation surfaces, the contact surfaces and the lower deformation surfaces are in an integral structure. The upper deformation surfaces and the lower deformation surfaces respectively contact the limiting mechanisms. Wire contact is changed into surface contact, and a spiral wire spring is replaced by the surface contact spring. Pressure is equally distributed on a contact wall. A force imposed by each surface contact spring on each contact pad is equally distributed, which avoids the deformation of each contact pad.
