[0026] In order to make the above-mentioned purposes, characteristics and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, therefore, the utility model is not limited by the following disclosed specific embodiments.
[0027] As Figures 1 to 6 shown, for the embodiment of the application:
[0028] The plug-in terminal 10 comprises a main body part 101, an elastic part 102 and a plug-in part 103, the main body part 101 is an L-shaped bending structure 1011, the elastic part 102 and the plug-in part 103 are respectively located at both ends of the main body part 101, the width of the main body part 101 is greater than the width of the elastic part 102 and the plug-in part 103, the elastic part 102 is a fish-eye structure 1021 with an internal cavity, and the plug-in part 103 is an elongated strip shape. The fish-eye structure 1021 can be directly inserted into the conductive hole of the PCB board without welding to be locked in place, and the plug-in part 103 is inserted into the elastic structure 201 of the connecting piece, and the width difference between the main body part 101 and the elastic part 102 and the width difference between the main body part 101 and the plug-in part 103 can play the role of promoting the stop.
[0029] The plug-in part 103 is provided with protrusions 1031 on both sides, and the protrusions 1031 are symmetrical to each other along the length direction of the plug-in part 103. When the plug-in part 103 of the plug-in terminal 10 is installed in the elastic structure 201 of the connecting piece, the protrusions 1031 on both sides of the plug-in part 103 are in contact with the contact points 2011 on the elastic structure 201, and appropriate contact force is provided to help scrape off the oxide layer on the surface of the contact points 2011.

Regardless of the number and height of the protrusions 1031, the technical effect of removing the oxide layer on the surface of the contact points 2011 can be well achieved.
[0031] The fish-eye structure 1021 and the protrusions 1031 are formed by cutting, and the L-shaped bending structure 1011 of the main body part 101 is formed by bending.
