Abstract: An electrical connector includes a generally cylindrical conductive housing, a conductive cable-engaging member and a hollow, elongated insulating member which is fitted in the conductive housing. The conductive cable-engaging member has an elongated intermediate section, two engaging units extending lengthwise from the ends of the intermediate section, and two first shoulder portions. The insulating member has two closed ends, two receiving spaces for receiving the engaging units of the cable-engaging member, and a restricted space interconnecting the receiving spaces for receiving the intermediate section of the cable-engaging member. Each of the closed ends of the insulating member has a through-hole formed therein. Each of the receiving spaces is adjacent to and communicates with a respective one of the through-holes.
