Embodiment 1

[0043] Example as image 3 : The two contact pieces 2 are directly fixed with the lower box body 6 .

Embodiment 2

[0044] Example two such as Figure 4 : The lower ends of the two contact pieces 2 respectively extend outward and then extend downward to the bottom of the lower box body 6 and then extend inwardly to intersect with another contact piece 2 to form a connecting portion 5 . The fixed sleeve only covers the deformed surface 8 of the C-shaped surface contact spring 3, and the fixed sleeve is fixed on the upper box body 6.

[0045] The fixing sleeve can also limit the connecting portion 5 of the contact piece 2 together to prevent the C-shaped surface contact spring 3 from being dislocated.

Embodiment 3

[0046] Embodiment three such as Figure 5 : The lower ends of the two contact pieces 2 respectively extend to the outside and then extend downward to the bottom of the box body 6 and then extend to the inside to intersect to form the connecting portion 5 . The lower ends of the two contact pieces 2 protrude from the lower edge of the fixing sleeve and are connected through the connecting portion 5 . The width of the connecting portion 5 is greater than that of the fixing sleeve. The fixed sleeve only covers the deformed surface 8 of the C-shaped surface contact spring 3, and the fixed sleeve is fixed on the upper box body 6.

Abstract

The invention provides a socket, which solves the problem of poor contact between the contact piece and the plug of the existing socket, temperature rise, unstable clamping force, large and unstable insertion force, large amount of wear of the contact piece, and easy deformation, which affects the stability of the socket. sex issue. It includes a box body and a contact piece, and also includes a surface contact spring and a limit mechanism. The surface contact spring includes a contact surface in contact with the outer surface of the contact piece, an upper deformation surface connected with the upper end of the contact surface, and a contact surface connected with the lower end of the contact surface. On the lower deformation surface, the free end of the upper deformation surface turns back and bends back to the contact piece, and the free end of the lower deformation surface turns back and bends back to the contact piece. The upper deformation surface, the contact surface and the lower deformation surface are an integral structure. The surfaces are respectively in contact with the limit mechanism. Change the line contact to surface contact and replace the helical wire spring with a surface contact spring. The pressure is evenly distributed on the contact wall, so that the force of the surface contact spring on the contact piece is evenly distributed, and the deformation of the contact piece is avoided.

Description

technical field [0001] The invention relates to a socket, in particular to a socket which can be in contact with a plug surface. Background technique [0002] The contacts of the earliest plug-in structure are all U-shaped structures made of elastic materials. The lower end is fixed, and the purpose of close contact with the plug is achieved through the elasticity of the material itself; the structure is as follows figure 1 shown. When the plug is inserted, the contacts of the plug-in structure are required to be conductive and have a certain clamping force, so the contacts can only be made of special copper materials such as phosphor copper. However, elastic copper or alloy materials such as phosphorus and molybdenum have great limitations as contacts, such as unstable elastic force, large conductive resistance, and high material cost. This structure is actually just line contact or point contact, which directly leads to large concentrated resistance or shrinkage resistan...
