Abstract
Abstract A connector assembly for tapping an energized underground distribution cable. The connector includes a two-section metallic housing which may be assembled and clamped around a properly prepared portion of the cable which is to be tapped. The housing includes a threaded opening into which a bushing plug is inserted. A conductor stud in the bushing plug has a pointed and threaded end which pierces the insulation and the inner conductor of the tapped cable. Insulating material is injected into the housing and a load-break connector is inserted into terminal on the bushing plug to complete the tap. The threads of the housing opening and of the stud end have the same pitch to provide the force for penetrating the insulation and the inner conductor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
An electrical connector for tapping a concentric electrical cable, comprising: a housing disposable around the cable to be tapped; a plug inserted through an opening in said housing, said plug having threads thereon which are engageable with threads on said housing; terminal means located on said plug and adapted for electrical connection of a tapping cable; and piercing means for penetrating the insulation around the inner conductor of the cable to be tapped, said piercing means being located on said plug and being electrically connected to said terminal means, with the threads on said plug and housing advancing the piercing means toward the inner conductor when the plug is rotated, thereby forcing the piercing means through the cable insulation and into the inner conductor to establish electrical contact, said piercing means comprising an electrical conducting stud having a substantially pointed end, said stud including threads thereon which have the same pitch as the threads which engage the plug and the housing.
Claim 2
Dependent Claim
161 words
An electrical connector for tapping a concentric electrical cable, comprising: a housing disposable around the cable to be tapped; a plug inserted through an opening in said housing, said plug having threads thereon which are engageable with threads on said housing; terminal means located on said plug and adapted for electrical connection of a tapping cable; and piercing means for penetrating the insulation around the inner conductor of the cable to be tapped, said piercing means being located on said plug and being electrically connected to said terminal means, with the threads on said plug and housing advancing the piercing means toward the inner conductor when the plug is rotated, thereby forcing the piercing means through the cable insulation and into the inner conductor to establish electrical contact, said piercing means comprising an electrical conducting stud having a substantially pointed end, said stud including threads thereon which have the same pitch as the threads which engage the plug and the housing.
Claim 3
Dependent Claim
18 words
The electricAl connector of claim 1 wherein the stud is embedded in and extends substantially through the plug.
Claim 4
Dependent Claim
62 words
The electrical connector of claim 1 wherein the housing comprises a bottom section constructed of an electrical conducting material, and a top section constructed of an electrical conducting material, said top section containing the opening through which the plug is inserted, with the threads on said housing extending around the inside of the portion of the top section which defines the opening.
Claim 5
Dependent Claim
33 words
The electrical connector of claim 1 wherein the plug comprises a body portion constructed of an electrical insulating material, with the threads on the plug extending around the outside of said body portion.
Claim 6
Dependent Claim
28 words
The electrical connector of claim 1 wherein the terminal means is located at an end of the plug and is adapted for engagement with a load-break electrical connector.
Claim 7
Dependent Claim
33 words
The electrical connector of claim 1 wherein a cable supporting block is attached to the housing and is positioned to support the cable when the piercing means is being forced into the cable.
Claim 8
Dependent Claim
26 words
The electrical connector of claim 1 wherein a solid insulating material substantially fills the space between the exposed portion of the piercing means and the housing.
Claim 9
Dependent Claim
101 words
An electrical connector for tapping an energized concentric electrical cable, comprising: a metallic housing suitable for placement around the cable to be tapped, said housing containing a threaded opening therein; a plug containing a metallic stud embedded in an insulated body portion of said plug, said body portion containing threads around the outside thereof; and terminal means for electrically connecting the tapping cable to said stud, with an end of said stud being substantially pointed and having threads disposed thereon, with the threads on said stud and the threads around the body portion of said plug having substantially the same pitch.
Claim 10
Dependent Claim
101 words
An electrical connector for tapping an energized concentric electrical cable, comprising: a metallic housing suitable for placement around the cable to be tapped, said housing containing a threaded opening therein; a plug containing a metallic stud embedded in an insulated body portion of said plug, said body portion containing threads around the outside thereof; and terminal means for electrically connecting the tapping cable to said stud, with an end of said stud being substantially pointed and having threads disposed thereon, with the threads on said stud and the threads around the body portion of said plug having substantially the same pitch.
