The first guide core 22 is located at the center of the central portion 24. The first core 22 has a projection 221 at the front end of the plug 21. The outer side of the spring leaf 25 is provided with a clamping convex 26.
The plug 21 can be inserted into the socket 12. When the plug 21 is inserted into the socket 12, the locking protrusion 26 can be locked into the locking groove 14, and at this time, the first guide core 22 is inserted into the through hole 15. When the two second connectors 2 are inserted into the two sockets 12 of the first connector 1, and the locking protrusions 26 of the second connectors 2 are locked into the locking slots 14 of the first connector 1, the first guide cores 22 of the two second connectors 2 are inserted into the through holes 15, and the first guide cores 22 inserted into the through holes 15 are butted in the through holes 15 in an end connection manner, so that the first guide cores 22 of the two second connectors 2 are electrically connected through the first connector 1.
