Abstract

The invention discloses a plug device used for electrical connection, which comprises a metal piece and an elastic steel slice surrounding the periphery of the metal piece, wherein, the metal piece comprises two elastic side lags which are arranged oppositely and connected by a lath; the elastic steel slice comprises two clamping side parts which are arranged oppositely and one end of one clamping side part is connected with one end of the other clamping side part by a coating ring plate; the position of the coating ring plate is corresponding to the position of the lath and the coating ring plate coats the tail part of the metal piece and the other end of the two clamping side parts contacts the outer side of the contacting parts of the two elastic side lags respectively. The device has the advantages that: (1) the elastic steel slice and the metal piece are in close fit, which overcomes the disadvantage that the acting force of the elastic steel slice in the prior art is little; (2) the elastic side lags of the metal piece are provided with open grooves, which leads to two-points connection between the elastic side lags and components to be connected and prevents looseness; the grooves are good for heat elimination and the plug device is especially applicable to occasions where through current is relatively large.

Description

1. Technical field [0001] The invention relates to an electrical connection device, in particular to a plug-in device connected with electrical components to be connected in a terminal block. 2. Background technology [0002] The function of the terminal is to connect electrical devices that are independent of each other to form electrical contact or connection, that is, to form a conductive connection between one electrical component and another electrical component. For example, in the field of printed circuit board terminals, the connector that connects the wires to the socket on the printed circuit board is an important type. It must not only ensure the reliability of the electrical connection, but also ensure the ability to perform multiple It can be plugged and unplugged without degrading the effect of its connection. The metal part of this type of connector is generally made of copper material. Copper material has excellent electrical conductivity, but its elasticity...
