[0005] Preferably, the needle seat is provided with three, three needle seats are equidistantly distributed on the top of the mounting seat.

[0006] Preferably, the threaded column is slidably connected with the mounting hole, and the inner wall of the mounting hole is attached to the threaded column.

[0007] Preferably, the inner wall of the guide hole is adapted to the outer wall of the guide column, and the guide column is slidably inserted into the guide hole.

[0008] Preferably, one end of the resistance spring abuts against one end of the inner chamber of the guide hole.

[0009] Preferably, the other end of the resistance spring abuts against one end of the guide column.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this elastic pin-type multi-core electrical connector, repeated connections after long-term use of the spring pin connector can cause the elasticity of the spring inside the spring pin connector to deteriorate, affecting the reset of the contact head and easily leading to unstable connection. However, by placing the spring in the guide tube and then screwing the threaded post into the threaded hole, after it is fully screwed in, the threaded post is placed in the mounting hole and slides with the mounting hole, thus completing the installation of the pin head. The end of the guide post will be inserted into the guide hole and abut against one end of the spring, thus completing the assembly. The threaded post design makes it easy to replace the spring.
