Cable connector

Claim 1

A cable entry for mechanically securing an electrical cable in attached sealing relation to an electrical enclosure, the entry comprising. a cylindrical body portion having an axial bore therethrough; securing means located at a forward end of the body portion for securement of the body portion to the electrical enclosure; expansible chuck means to receive an armor portion of said cable in inserted relation therein, said chuck means being radially compressible, in use, into gripping relation with the cable armor portion; a tapered radially outer portion of the chuck means making contact with a radially inner tapered portion of the body portion; compression nut means threadedly attached to the body portion in axial compressive relation with the chuck means, to radially compress the chuck means into gripping relating with the cable armor, recess means to receive in use an resilient seal in sealing engagement between the electrical cable and the cable entry; and annular nut means threadedly secured to said forward end threaded surface having an inwardly extending annular skirt portion, in use to retain sealant inserted within said forward body portion.

Claim 3

The method of securing an armored electrical cable in mechanically secured, sealing relation with an entry port of an electrical enclosure, comprising the steps of: preparing one end of a cable to be connected through a predetermined access port to within an electrical enclosure, including removing a requisite length of the armour thereof from the selected end of the cable; inserting a compression nut and ring of an attachment means axially over the armor of the cable in an outward facing position; applying chuck means about the surface of a portion of the armor in axially located relation to align annular serration portions of the chuck means in axially engaging relation with outwardly protruding helix portions of the armor; securing a hollow cylindrical body to the entry port of the electrical enclosure; inserting chuck means axially within the cylindrical body in axial engaged, radially constricted relation therewith, to secure the chuck means in engaged relation with the armor; engaging the compression nut in threaded relation with the cylindrical body and rotating the nut to axially compress the chuck means into radially constrained gripping relation with the armor thereby securing the prepared cable end in inserted relation through the enclosure port; and applying a resilient sealant in sealing relation between a portion of the cable and the attachment means, said resilient seal applied as a sealing coating within the enclosure in inserted engaging relation, to enter and set within at least one recess of the attachment means in sealing and axial restrained relation therewith.

Claim 4

The method of securing an armored electrical cable in mechanically secured, sealing relation with an entry port of an electrical enclosure, comprising the steps of: preparing one end of a cable to be connected through a predetermined access port to within an electrical enclosure, including removing a requisite length of the armour thereof from the selected end of the cable; inserting a compression nut and ring of an attachment means axially over the armor of the cable in an outward facing position; applying chuck means about the surface of a portion of the armor in axially located relation to align annular serration portions of the chuck means in axially engaging relation with outwardly protruding helix portions of the armor; securing a hollow cylindrical body to the entry port of the electrical enclosure; inserting chuck means axially within the cylindrical body in axial engaged, radially constricted relation therewith, to secure the chuck means in engaged relation with the armor; engaging the compression nut in threaded relation with the cylindrical body and rotating the nut to axially compress the chuck means into radially constrained gripping relation with the armor thereby securing the prepared cable end in inserted relation through the enclosure port; and applying a resilient sealant in sealing relation between a portion of the cable and the attachment means, said resilient seal applied as a sealing coating within the enclosure in inserted engaging relation, to enter and set within at least one recess of the attachment means in sealing and axial restrained relation therewith.
