Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, including a terminal 1, wherein one end of the terminal 1 is provided with a connection end 2, the connection end 2 of the terminal 1 is inserted into a copper ring base 3, the copper ring base 3 is provided with a connection hole 7 connected with the connection end 2, the copper ring base 3 is arranged in an "i" shape or a "T" shape, the connection hole 7 on the copper ring base 3 is arranged as a blind hole or a through hole, when the connection hole 7 is arranged as a blind hole, the connection hole 7 is arranged as a special-shaped groove near one side inside the copper ring base 3, the special-shaped groove is conical, the elastic universal power terminal can be more accurately installed by increasing the end face elastic connection position, the aperture tolerance of the PCB can be wider, because the connection to the initial position of the PCB is a straight needle, the tool for PCB installation can be relatively less precise, and the PCB can be more firmly fixed and limited by an elastic body after the PCB is inserted, the special-shaped copper ring base can save 20% of raw materials of the copper ring base through special-shaped, the special-shaped position is easy to increase the firmness of welding, through holes do not need to be divided into directions, the production efficiency is greatly improved, the copper ring base 3 is polygonal, the other end of the terminal 1 is fixedly connected with the connecting rod 4, the outer side of the connecting rod 4 is wrapped with the elastic body 5 connected with the terminal 1, the other end of the connecting rod 4 is connected with the transition polished rod 6, the elastic body 5 is connected with the transition polished rod 6, the connecting rod 4 and the terminal 1 are located on the same central line, the transition polished rod 6, the connecting rod 4 and the terminal 1 are of an integrated structure, the elastic body 5 is symmetrically distributed on two sides of the connecting rod 4 by taking the connecting rod 4 as the central line, the diameter of the.
