Abstract

Abstract The insulated standoff bushing is used for terminating a connector probe connected to a high voltage circuit. The standoff bushing includes an insulated body having a bore for receiving a shielded housing. The shielded housing in turn has an aperture for receiving a contact which is secured within the aperture. The contact is in the form of a spring having opposed sides with contact pads. The connector probe is inserted into the aperture of the shield housing and passes between the opposed contact pads for the dissipation of current into the insulated standoff bushing.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 104 words
A standoff for terminating and parking a connector probe, comprising: an insulated housing having a bore; a shield member disposed within said bore and having an aperture adapted to receive the connector probe; a contact slidingly disposed within said aperture, said contacting having minor dimensioned side and opposed major dimensioned sides; said contact having a passageway with a contracted position where said opposed major dimensioned sides are contracted and an expanded position where said opposed major dimensioned sides are expanded; and said passageway adapted to receive the connector probe whereby said opposed major dimensioned sides are expanded from said contracted to said expanded position.
Claim 2
Dependent Claim 104 words
A standoff for terminating and parking a connector probe, comprising: an insulated housing having a bore; a shield member disposed within said bore and having an aperture adapted to receive the connector probe; a contact slidingly disposed within said aperture, said contacting having minor dimensioned side and opposed major dimensioned sides; said contact having a passageway with a contracted position where said opposed major dimensioned sides are contracted and an expanded position where said opposed major dimensioned sides are expanded; and said passageway adapted to receive the connector probe whereby said opposed major dimensioned sides are expanded from said contracted to said expanded position.
Claim 3
Dependent Claim 24 words
The standoff of claim 1 wherein said contact includes opposed contact pads on said opposed major dimensioned sides for engagement with the connector probe.
Claim 4
Dependent Claim 11 words
The standoff of claim 1 wherein said contact is a spring.
Claim 5
Dependent Claim 25 words
The standoff of claim 3 wherein said spring is generally oval-shaped, said minor dimensioned side forming a closed end between said opposed major dimensioned sides.
Claim 6
Dependent Claim 24 words
The standoff of claim 4 wherein each of said opposed major dimensioned sides includes a contact pad adapted for engagement with the connector probe.
Claim 7
Dependent Claim 19 words
The standoff of claim 1 further including means for securing said contact against said shield member within said aperture.
Claim 8
Dependent Claim 17 words
The standoff of claim 2 wherein said contact pads are stamped into said opposed major dimensioned sides.
Claim 9
Dependent Claim 30 words
The standoff of claim 2 wherein said opposed contact pads are rectangular in shape and have a major dimension which is parallel to the connector probe in said expanded position.
Claim 10
Dependent Claim 26 words
The standoff of claim 1 wherein said aperture is cylindrical with a diameter and said opposed major dimensioned sides have a length less than said diameter.
Claim 11
Dependent Claim 16 words
The standoff of claim 6 wherein said securing means includes a member disposed within said aperture.
Claim 12
Dependent Claim 152 words
An insulated standoff bushing for terminating a connector probe, comprising: a body having an axial first bore with a first enlarged diameter portion; a shield housing having a second enlarged diameter portion and an axial second bore with a third enlarged diameter portion; said first bore receiving said shield housing with said second enlarged diameter portion of said housing being disposed within said first enlarged diameter portion of said first bore; said third enlarged diameter portion forming an annular shoulder; a contact in the form of a generally C-shaped spring having an opening therethrough between opposed sides and disposed within said third enlarged diameter portion adjacent said annular shoulder such that said opening is coaxial with said second bore; a nose piece with a third bore and threadingly engaged with said shield housing and having a terminal end adjacent said contact to secure said contact between said annular shoulder and nose piece.
Claim 13
Dependent Claim 152 words
An insulated standoff bushing for terminating a connector probe, comprising: a body having an axial first bore with a first enlarged diameter portion; a shield housing having a second enlarged diameter portion and an axial second bore with a third enlarged diameter portion; said first bore receiving said shield housing with said second enlarged diameter portion of said housing being disposed within said first enlarged diameter portion of said first bore; said third enlarged diameter portion forming an annular shoulder; a contact in the form of a generally C-shaped spring having an opening therethrough between opposed sides and disposed within said third enlarged diameter portion adjacent said annular shoulder such that said opening is coaxial with said second bore; a nose piece with a third bore and threadingly engaged with said shield housing and having a terminal end adjacent said contact to secure said contact between said annular shoulder and nose piece.
Claim 14
Dependent Claim 19 words
The bushing of claim 11 wherein said sides of said contact have contact pads for engaging the connector probe.
Claim 15
Dependent Claim 16 words
The bushing of claim 11 wherein said body further includes a semi-conductor outer jacket molded thereto.
Claim 16
Dependent Claim 122 words
An electrical terminator for terminating an electrical circuit, comprising; a connector having a probe connected to a high voltage circuit; a standoff bushing having an insulated housing with a central bore; a shield member disposed within said bore and having an aperture; a spring having opposed sides with a closed end; opposed contact pads mounted on said opposed sides for biasing said opposed contact pads toward each other in a contracted position, aid opposed contact pads disposed in said aperture; said probe being received within said aperture and disposed between said opposed contact pads making electrical contact therewith; said standoff bushing having means for stabilizing and maintaining said probe within said aperture of said standoff bushing to terminate the high voltage circuit.
Claim 17
Dependent Claim 122 words
An electrical terminator for terminating an electrical circuit, comprising; a connector having a probe connected to a high voltage circuit; a standoff bushing having an insulated housing with a central bore; a shield member disposed within said bore and having an aperture; a spring having opposed sides with a closed end; opposed contact pads mounted on said opposed sides for biasing said opposed contact pads toward each other in a contracted position, aid opposed contact pads disposed in said aperture; said probe being received within said aperture and disposed between said opposed contact pads making electrical contact therewith; said standoff bushing having means for stabilizing and maintaining said probe within said aperture of said standoff bushing to terminate the high voltage circuit.
