Small plug-in connector with wire locking function

Abstract

The invention discloses a small plug-in connector with a wire locking function. The connector comprises a plastic shell and a locking mechanism arranged in the plastic shell. The locking mechanism comprises an elastic sheet terminal and a contact conductive terminal which are oppositely arranged; and the elastic sheet terminal and the contact conductive terminal are used for clamping an electric wire inserted between the elastic sheet terminal and the contact conductive terminal through elastic deformation. According to the small plug-in connector provided by the invention, the wire locking function is realized through the cooperation of the two metal parts, namely the elastic sheet terminal and the contact conductive terminal, and through the two metal parts, the clamping force can be improved, and meanwhile, the conductive function is also realized; and according to the small plug-in connector provided by the invention, the clamping force is enough so that the size of the elastic sheet terminal is reduced, the size of the plastic shell is further decreased, product miniaturization is realized, the use space is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a small plug-in connector with a wire locking function. Background technique [0002] Traditional rectifier connectors are generally connected by screw-fixed wires. The product takes up a lot of space, and some auxiliary tools are needed during the operation, and the operation is relatively cumbersome. Moreover, this connection method is prone to poor contact and increased power consumption. Conducive to the development of small energy-saving products. [0003] In addition, if figure 1 As shown, there is also a plug-in connector in the prior art. The plug-in connector includes a plastic housing a and a locking mechanism arranged in the plastic housing a, wherein the locking mechanism includes an elastic crimp terminal b, and the elastic force The crimping terminal b is made of conductive copper, and the elastic crimping terminal b will be elastically deformed. There is a spa...

AI Technical Summary

Problems solved by technology

[0004] Since the plug-in connector has only one elastic crimping terminal, and the elastic force of the plastic shell is negligible, the clamping force is small, which is prone to poor contact; in addition, since the locking mechanism has only one elastic crimping terminal, it is not good Realize the clamping force, so the size of the terminal should be designed large enough, otherwise the clamping force is not enough, so the size of the plastic shell is increased, which in turn increases the size of the connector, which is not suitable for use in a small space
