  • Patent number: 7824203
    Abstract: An apparatus to connect a connector half (13) at an end of a first cable (15) to a second cable (6) is described as having a male member (32) coupled to the first cable (15) and a female member (31) coupled to the second cable (6). An actuation mechanism includes a tapered surface (33U; 33L) where at least a part (16) of one of the first and second cables is connected to the tapered surface (33U; 33L) by a trapping means (33L; 16L). Preferably, the apparatus is arranged such that movement of the tapered surface (14; 33U; 33L) along a longitudinal axis in a first direction forces the said part (16) to move radially outwardly to form the connection and movement of the tapered surface (33U; 33L) in the opposite direction along the longitudinal axis forces the said part (16) to move radially inwardly to break the connection. Preferably, the trapping means (33L; 16L) is a key (16L) provided on the said part (16) and a slot (33L) formed in the mandrel (14) in which the key (16L) is trapped.

  • Patent number: 6530794
    Abstract: An apparatus to connect two portions of at least one cable together comprising a male member, a female member and an actuation means. The actuation means is adapted to radially displace the first or second portions of the cables to engage each other. The actuation means typically comprises a tapered rod, and the male member is normally inserted into the female member and the rod is moved along its central axis so that engaging portions abutting against the rod move radially outwards causing the attached cable portions to move radially outward. Secondary portions of the cables are typically positioned around the female member and form a connection with the cables pushed radially outwards.
