Electrical connector and drilling system

Abstract

The present invention provides an electrical connector comprising a socket and a plug. A jack is set on the socket, and a socket pin is set in the jack. The plug is set with a plug pin that has a one-to-one correspondence with the socket pin. The plug has an insertion part that is in insertion fit with the jack, and the end part of the insertion part is set with a first groove that extends along its insertion direction. The plug pin has a one-to-one correspondence with the first groove, and has an exposed part that is exposed in the first groove. The electrical connector further comprises a first compression spring, which has a one-to-one correspondence with the first groove. The two ends of the first compression spring respectively abut against the inner wall of the two ends of the first groove. The first compression spring is detachably mounted on and contact the exposed part in the corresponding first groove. The socket pin contacts the corresponding first compression spring as the jack becomes in insertion fit with the insertion part of the plug. The invention further provides a drilling system. The solution of the present invention can solve the problem of the prior art that the operation is complex and the cost is high when the connection stability of the electrical connector is ensured by way of replacing pins.
