Abstract
Abstract This invention relates to a connector device for splicing or providing terminal anchoring means for large diameter electrical cables such as power transmission cables. The novel connector includes a shell which is tapered either on each end or on one end. Within the shell, a firing chamber is provided having either one or two pistons or projectiles driven outwardly towards the tapered end. These pistons are centrally and axially located in reference to the firing chamber and drive piston or ram plates thereby transmitting power to individually acting jaw means which upon firing an explosive charge securely engage the cable inserted from one or both ends of the opening. Various means by which the spacing and the prevention of a ''''bird cage'''' forming during the actual explosive, splicing operation takes place have also been disclosed. Additionally, the connector herein contains means for securing a steel core in an aluminum steel reinforced cable commonly employed in the utilities industry. The present device affords a convenient and practical means for splicing cables in remote locations without the necessity of providing elaborate hydraulically operated equipment previously employed in crimping large diameter cables. A connector wherein only one end is swaged is used for deadending the power cables.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
123 words
In an electrical connector capable of being secured electrically to an electrical conductor, and including at least one tapered shell and a plurality of jaws movable toward a narrow end internally of said tapered shell, said jaws also being movable radially inward to grip the end of an electrical conductor inserted in said shell, the improvement comprising: a plug received and slidable between said jaws, and a retaining member, said retaining member initially retaIning said plug within the narrow end of said tapered shell prior to insertion of said electrical conductor within said shell, said plug being frangibly connected to said retaining member in order to be slidable between said jaws and guide said conductor internally of said shell and between said jaws.
Claim 2
Dependent Claim
123 words
In an electrical connector capable of being secured electrically to an electrical conductor, and including at least one tapered shell and a plurality of jaws movable toward a narrow end internally of said tapered shell, said jaws also being movable radially inward to grip the end of an electrical conductor inserted in said shell, the improvement comprising: a plug received and slidable between said jaws, and a retaining member, said retaining member initially retaIning said plug within the narrow end of said tapered shell prior to insertion of said electrical conductor within said shell, said plug being frangibly connected to said retaining member in order to be slidable between said jaws and guide said conductor internally of said shell and between said jaws.
