Referring to fig. 9 and 10, in one embodiment, the male end 7 of the electrical connector further includes a top block 76, the top block 76 is disposed on a surface of the male end 7 of the electrical connector, the top block 76 is engaged with the anti-electric-shock portion 4 in the female end of the electrical connector, the top block 76 is used for triggering the anti-electric-shock portion 4, and when the male end 7 of the electrical connector is engaged with the female end of the electrical connector, the top block 76 extends into the anti-electric-shock portion 4 and triggers the trigger block on the anti-electric-shock portion 4, so that the trigger block in the anti-electric-shock portion 4 can be disposed inside the anti-electric-shock portion 4 (as shown in fig. 10), the anti-electric-shock push rod 42 is retracted into the anti-electric-shock hole 41, and when the male end 7 of the electrical connector is engaged with the female end of the electrical connector, the top block 76 extends into the anti-electric-shock hole 41 and acts on the anti-electric-. Furthermore, the electric shock prevention push rod 42 is contracted in the electric shock prevention hole 41, so that the electric shock prevention part 4 is not easy to be touched by mistake to cause the electric shock prevention function of the female end of the electric connector to be closed, and the electric shock risk is further reduced.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
