Abstract
The invention discloses an electric plug connector. The electric plug connector comprises an insulating body, a plurality of plugging holes formed in the first side of the insulating body, and a plurality of plugging pins installed at the second side of the insulating body, wherein the plugging pins and the plugging holes are in one-to-one correspondence and keep electrical connection, an electric conductor making contact with the corresponding plugging pin is arranged at the bottom of each plugging pin, and the electric conductors can be exposed out of the insulating body. When a system fault happens and fault detection needs to be conducted on a cable, a user just needs to use an electroprobe to test whether the exposed electric conductors have electric signals, then whether the cable has a fault or not can be judged, and therefore the entire test process is more convenient and rapid; in addition, the electroprobe does not make contact with a welding point in the test process, so the welding point will not be damaged.
