ABSTRACT:
The invention provides for electrical coupling pins 5 for interconnecting two opposed electrical cable terminals having sockets 3, at least one of said sockets having a male contact member with a tapered end portion.
The coupling pins each include a hollow tubular member 21 and two electrically interconnected contact members mounted for relative movement therebetween along a longitudinal axis of the member 21 and resiliently biased away from each other.
At least one of the contact members 24 comprises a pair of segmental members 27, 27a resiliently biased away from each other transversely of the longitudinal axis of the member 21 and counterbored in the direction of said longitudinal axis to provide radially inner contact surfaces for closely contacting the tapered end portion of the male contact member when in use. According to a further aspect, the invention also provides for an electrical coupling including a pair of opposed cable terminals 2 each having at least one socket 3 therein, said coupling pin 5 according to the above first aspect being insertable in the socket or each socket to connect the cable terminals together. Each socket 3 is provided with a male contact member 19 engageable in the counterbore of the contact member 24 to effect a wedging action on the segmental members and to provide positive electrical contact between the male contact member and the counterbore surface and between the segmental contact members and the tubular member.
