In the present embodiment, the first insulating sleeve 23 is provided with a conductive layer 24 inside to form the conductive jack 22, wherein the conductive layer 24 is used for contacting with the conductive pin 12, so as to realize the transmission of electrical signals; when the conductive contact pin is inserted into the conductive contact pin hole, the second insulating sleeve positioned on the first insulating sleeve is matched with the through hole on the conductive contact pin for sleeving, so that the tight connection between the conductive contact pin and the conductive insertion hole can be realized, the insertion looseness caused by frequent disassembly can be avoided, and the conductive contact pin inserting device is suitable for connection between electrical equipment which is frequently inserted and pulled.
