Coaxial cable connector
First Claim
1. An electrical connector for coupling to an electrical conductor of the type having an inner conductor enclosed with an inner insulation and a generally concentric conductive sheath around said inner insulation and enclosed in an outer insulation, said electrical connector comprising:
- a housing having an electrically conductive portion and a bore therein;
at least one electrically conductive prong having two end portions, said conductive prong attached to said housing and having an portion protruding axially into said housing bore piercing into an end of the electrical conductor and making electrical contact with the inner conductor of the electrical conductor;
an electrically conductive clamp electrically connected to, and extending outwardly from a front end of, said electrically conductive portion of said housing and insulated from said electrically conductive prong, said electrically conductive clamp having a pointed end sized for driving through the outer insulation of the electrical conductor and making electrical contact with the conductive sheath without contacting the inner conductor;
a generally cylindrically shaped housing cap member attachable to said housing and having means for driving said electrically conductive clamp through the outer insulation of the electrical conductor to make electrical contact with the conductive sheath when said cap member is attached to said housing to thereby form a conductive path between the conductive sheath and the electrically conductive portion of said housing.

Abstract
An electrical connector for coupling to a coaxial cable of the type having an inner conductor enclosed in an inner concentric insulation and having a generally concentric conductive sheath therearound and an outer insulation enclosing the conductive sheath. The connector has a housing having an electrically conductive portion and a bore therein. An electrically conductive pin has one end protruding axially into the housing bore and the second prong end extending in an opposite direction within a second housing bore. One or more conductive arms are electrically connected to the conductive housing portion and insulated from the electrical conductive prong and having pointed ends sized for driving the clamp into the outer insulation and into the conductive sheath without contacting the center conductor. A closure member for enforcing engagement of the pointed ends of the conductive arms into the outer insulation.

14. A connector attachable to a coaxial cable having an inner central conductor and an outer concentrically disposed conductor separated by a concentrically disposed insulation layer and enclosed in an outer insulation, said connector comprising:
-
a housing having a central, substantially cylindrical opening, a wall separating said opening to define first and second chambers, and a conductive arm extending outwardly from a front end of said housing at said first chamber; said conductive arm having an end contact portion extending substantially radially inwardly and including a piercing structure; an axially extending pin member and an insulating body secured to said pin member, said insulating body being secured centrally in said housing in abutment with said wall, said pin extending into said first and second chambers; said pin member having a pointed end portion for piercing into an end of the electrical conductor and making electrical contact with the inner central conductor; and a generally cylindrically shaped cover member, surrounding and extending beyond the cylindrical opening of said housing at said first chamber, said cover member having means for abutting said conductive arm and urging said arm radially inwardly to cause said contact portion to pierce the outer insulation of the coaxial cable and establish electrical contact with the outer concentrically disposed conductor when the coaxial cable is positioned in said first chamber.
