Embodiment 1

[0025] Embodiment one: see figure 2 , a plug-in component, including two oppositely arranged plate-type contact pieces 1, the lower end of the contact piece 1 is an integral structure, which can meet the torsional deformation in a small angle range, increase the stability of the contact piece; at the same time, reduce the The one-time welding with the wire improves the reliability of the contact sheet 1, and the reduction of the solder joints also reduces the contact resistance. After the two contact pieces are bent outward, they continue to extend upward and bend inwardly to form the return spring 2, and the two contact pieces have a symmetrical structure. The end of the return spring 2 is provided with a limit plate 3 perpendicular to the contact piece 1. The limit plate 3 can prevent the return spring from being over-pressed, so that the return spring is in the best state and prolongs the service life of the plug-in parts , The tops of the two contacts form a V-shaped soc...

Embodiment 2

[0026] Embodiment two: see image 3 and Figure 4 , a plug-in component, the fixed sleeve 6 includes two oppositely arranged plate-type contact pieces 1, the lower end of the contact piece 1 is an integrated structure, which can meet the torsional deformation in a small angle range, and the surface contact and plane pressure increase the contact. The stability of the chip; at the same time, the one-time welding with the wire is reduced, the reliability of the contact piece 1 is improved, and the reduction of the solder joints also reduces the contact resistance. After one of the contacts is bent outwards, it continues to extend upwards and bends inwards to form a return spring 2 . The end of the return spring 2 is provided with a limiting plate 3 perpendicular to the contact piece 1 . The tops of the two contacts form a V-shaped socket, which is convenient for the insertion of the object to be contacted. This structure can be applied to terminal connectors. Figure 4 yes ...

Abstract

The invention relates to an insertion part. The insertion part comprises two plate-type contact pieces connected integrally and arranged in parallel, wherein a U-shaped structure is arranged at the lower end of each contact piece; one contact piece is bent towards the outer side, continues to extend to the upper side and is bent towards the inner side to generate a concentric-square-shaped spring; and the top end of the concentric-square-shaped ring has the same height as the other contact piece. According to the integrated surface contact insertion part provided by the invention, the technical problems of high generation cost and complicated process of an existing split product are solved; and the insertion part is formed once by adopting an integrated structure and can be produced by using only one material, and the spring does not need to be separately mounted and fixed, so that the material and machining costs are reduced.

Description

technical field [0001] The invention relates to a plug-in component, in particular to an integral surface-contact plug-in component. Background technique [0002] The existing plug-in parts that can be used for sockets, plug-in strips, knife switches, and terminal connectors are mostly made of elastic materials to make two parallel contact pieces, the lower ends of which are fixed, and rely on the elasticity of the material itself to achieve clamping. The purpose of holding the contacted object. The effect produced by this structure is actually line contact or point contact, which has the disadvantage of high contact resistance, which makes the current flow capacity low, and it is easy to generate heat and cause safety hazards. In addition, after a period of plug-in use of the traditional elastic contact piece, the elasticity of the material itself will be weakened, and the clamping ability will decrease, so that the contact piece cannot be in good contact with the contacte...
