It will be appreciated that the cover 24 may function to protect a plurality of probes 22 extending out of the socket 21. Moreover, when the length of the probe 22 is set such that the needle 220 of the probe 22 protrudes out of the socket 21 through the insertion hole 210, it is convenient to perform targeted removal and replacement conveniently and quickly when the individual probe 22 fails, so as to save the maintenance cost of the socket 21.

In the embodiment of the present invention shown in fig. 2, the material of the socket 21 includes an insulating material, and the material of the probe 22 includes a conductive material. In addition, one end of the needle sheath 222 is also provided with a welding position 224 which can be used for welding wires, so that after the plug 23 and the socket 21 are oppositely inserted through the probe 22, other instruments and the like can be electrically connected. Thus, the problem as described in the background art, that is, the insert structure having a plurality of pins can realize the need of frequent insertion and removal for many times without easily damaging the components, can be solved.
