Abstract

A cable connector assembly for sealably connecting the conductive sheath of an insulated cable. The connector assembly comprises a conductive member having insulation piercing contacts. The conductive member includes a spring element which is formed to provide a predetermined force by the contact on the cable. The assembly further includes a sealing enclosure for accommodating the conductive member and sealing the connection.

Claims

1. A connector for electrical cable having a conductive sheath surrounded by an insulative jacket, said connector comprising:

a base for supporting said cable;

a conductive member movably secured to said base, said conductive member including a support surface;

a cantilevered spring supported by said support surface including a first cantilevered portion extending from said support surface of said conductive member and a second cantilevered portion extending from an unsecured end of said first cantilevered portion back toward said support surface;

a contact portion on said second cantilevered portion movably supported relative to said support surface; and

contact portion including an insulation piercing contact for contacting said cable upon movement of said conductive member;

said cantilevered spring formed to provide a predetermined force by said insulation piercing contact on said cable upon moving said conductive member towards said base, said predetermined force being greater than the resistance of said insulative jacket and less than the resistance of said conductive sheath; and

clamping means for moving said conductive member toward said base.

2. The connector in accordance with claim 1 wherein said base includes a first aperture and said conductive member includes a second aperture alignable with said first aperture;

and

said clamping means includes a bolt interposed through said first and second aperture, and a nut threadably attached to said bolt.

3. The connector in accordance with claim 1 wherein said conductive member further includes means for visually determining the extent of penetration of said insulation piercing contact.

4. The connector in accordance with claim 1 wherein said base includes a second conductive member having an insulation piercing contact thereon for penetrating said insulative jacket of said cable and for contacting said conductive sheath upon relative movement of said first and second conductive members.

5. A connector for electrically connecting the conductive sheath of a pair of insulated cables comprising:

a pair of oppositely facing conductive elements supported for relative movement therebetween;

each of said conductive elements having a support surface and a pair of oppositely extending cantilevered springs, each of said cantilevered springs including a first cantilevered portion supported at one end by said support surface, and a second cantilevered portion supported at one end by the unsupported end of said first portion and extending toward said cable receiving region, the unsupported end of each second portion having a cable contacting portion said cable contacting portion of one of said pair of conductive element being aligned with said cable contacting portion of the other of said pair, and forming therebetween a pair of cable receiving regions for supporting said cables;

said contacting portions further including insulation piercing teeth extending into said cable receiving regions for engaging said cable upon said relative movement of said pair of conductive members;

said cantilevered spring selected to have a spring constant and configuration so as to provide a force by said insulation piercing teeth, upon said relative movement of said conductive members, greater than the resistance presented by the insulation of said cables and less than the resistance presented by said conductive sheaths; and

means for imparting said relative movement of said pair of conductive elements.

6. The connector in accordance with claim 5 wherein each of said contact portions is movable relative to both said support surface and respective said first cantilevered portion.

7. The connector of claim 5 wherein each contact member of said pair is hermaphroditic having interlocking portions thereon for mating engagement with opposite portions of the other said contact member of said pair.

8. The connector of claim 7 wherein said interlocking portions of said contact members form an alignment surface for properly aligning said cables in said cable receiving regions.
