Abstract
Abstract The disclosure relates to low cost high voltage connectors for use in about the 8KV AC range and 20 KV DC range. The connectors display relatively high physical strength and a removable cap, thereby eliminating the need for a separate dust cover since pressure sensitive tape can be placed over the hole in the cap.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
A high voltage electrical connector which comprises, in combination, a. a barrel of electrically insulating material, said barrel including a central groove and a hollow interior, said hollow interior including sections of differing cross-section and a shoulder therebetween, b. a threaded cap having an aperture positioned in said groove, c. an O-ring positioned in said groove within said cap and d. a threaded housing positioned over said barrel and threadable with said cap to place said O-ring in compression between said cap and said housing.
Claim 2
Dependent Claim
85 words
A high voltage electrical connector which comprises, in combination, a. a barrel of electrically insulating material, said barrel including a central groove and a hollow interior, said hollow interior including sections of differing cross-section and a shoulder therebetween, b. a threaded cap having an aperture positioned in said groove, c. an O-ring positioned in said groove within said cap and d. a threaded housing positioned over said barrel and threadable with said cap to place said O-ring in compression between said cap and said housing.
Claim 3
Dependent Claim
37 words
A high voltage electrical connector as set forth in claim 1 wherein said barrel and said cap are of semi-rigid material and said housing is of rigid material, said housing making an air-tight fit with said barrel.
Claim 4
Dependent Claim
59 words
A high voltage electrical connector as set forth in claim 1 further including a cable having insulation and a wire therein, said cable being positioned within said barrel, said insulation abutting said shoulder and the wire extending farther into said barrel, and an electrical terminal secured to said wire, said insulation making an air tight fit with said barrel.
Claim 5
Dependent Claim
59 words
A high voltage electrical connector as set forth in claim 2 further including a cable having insulation and a wire therein, said cable being positioned within said barrel, said insulation abutting said shoulder and the wire extending farther into said barrel, and an electrical terminal secured to said wire, said insulation making an air tight fit with said barrel.
Claim 6
Dependent Claim
37 words
A high voltage electrical connector as set forth in claim 3 wherein said cross-section of the interior of said barrel is greater in the region housing the insulation than in the region housing said wire and terminal.
Claim 7
Dependent Claim
37 words
A high voltage electrical connector as set forth in claim 4 wherein said cross-section of the interior of said barrel is greater in the region housing the insulation than in the region housing said wire and terminal.
Claim 8
Dependent Claim
39 words
A high voltage electrical connector as set forth in claim 3 wherein said cable further includes a braid surrounding said insulation, a ground wire strap positioned over said braid and a metal can crimped over said strap and braid.
Claim 9
Dependent Claim
39 words
A high voltage electrical connector as set forth in claim 4 wherein said cable further includes a braid surrounding said insulation, a ground wire strap positioned over said braid and a metal can crimped over said strap and braid.
Claim 10
Dependent Claim
39 words
A high voltage electrical connector as set forth in claim 5 wherein said cable further includes a braid surrounding said insulation, a groUnd wire strap positioned over said braid and a metal can crimped over said strap and braid.
Claim 11
Dependent Claim
39 words
A high voltage electrical connector as set forth in claim 6 wherein said cable further includes a braid surrounding said insulation, a ground wire strap positioned over said braid and a metal can crimped over said strap and braid.
