Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
An electrical coupling device comprising at least two first electrical connectors mounted in fixed position, each of said electrical connectors being in electrical contact with an electrical means, a shunt assembly comprising a conductive shunt bar, a mating electrical connector for each of said first electrical connectors, each said mating electrical connector being mounted upon and in electrical contact with said shunt bar and being capable of interengaging with one of said first electrical connectors, said first electrical connectors and said mating electrical connector for each thereof comprising pairs of male and female connector means, and control means for said shunt assembly capable of moving said shunt assembly in a first direction so that each of said first electrical connectors is simultaneously engaged by a said mating electrical connector, and also capable of moving said shunt assembly in a second direction so that disengagement of said first electrical connectors and said mating electrical connectors will occur.
Claim 2
Dependent Claim
156 words
An electrical coupling device comprising at least two first electrical connectors mounted in fixed position, each of said electrical connectors being in electrical contact with an electrical means, a shunt assembly comprising a conductive shunt bar, a mating electrical connector for each of said first electrical connectors, each said mating electrical connector being mounted upon and in electrical contact with said shunt bar and being capable of interengaging with one of said first electrical connectors, said first electrical connectors and said mating electrical connector for each thereof comprising pairs of male and female connector means, and control means for said shunt assembly capable of moving said shunt assembly in a first direction so that each of said first electrical connectors is simultaneously engaged by a said mating electrical connector, and also capable of moving said shunt assembly in a second direction so that disengagement of said first electrical connectors and said mating electrical connectors will occur.
Claim 3
Dependent Claim
53 words
An electrical coupling device as claimed in claim 1 wherein at least one of said electrical connectors comprises a male connector having a contact portion and an external surface on said contact portion, and pressure means within said contact portion for exerting a force urging said external surface on said contact portion outwardly.
Claim 4
Dependent Claim
61 words
An electrical coupling device as claimed in claim 2 wherein said pressure means comprises a slit in said contact portion dividing said contact portion into a plurality of segments, a Belleville washer within said slit, and means for retaining said Belleville washer within said slit, whereby said Belleville washer exerts said force urging said external surface on said control portion outwardly.
Claim 5
Dependent Claim
57 words
An electrical coupling device as claimed in claim 3 wherein said control means comprises fixed means disposed in fixed relationship to said first electrical connectors, and manipulation means in engagement both with said fixed means and said shunt assembly, operation of said manipulable means being capable of moving said shunt assembly in said first and second direction.
Claim 6
Dependent Claim
105 words
An electrical coupling device as claimed in claim 4 wherein said fixed means comprises an internally threaded member and said manipulable means comprises bolt means in said shunt bar, freely rotatable therein, said bolt means having a threaded end in engagement with said internally threaded member, and head and thrust collar means fixedly mounted on said bolt means on opposite sides of said shunt bar, said head bearing on said shunt bar when movement of said shunt assembly in said first direction is desired, and said thrust collar bearing on said shunt bar when movement of said shunt assembly in said second direction is desired.
Claim 7
Dependent Claim
61 words
An electrical connector for use with a mating connector having an internal recess, comprising a male connector having a contact portion and an external surface on said contact portion, a slit in said contact portion dividing said contact portion into a plurality of segments, a Belleville washer within said slit, and retaining means for retaining said Belleville washer within said slit.
Claim 8
Dependent Claim
61 words
An electrical connector for use with a mating connector having an internal recess, comprising a male connector having a contact portion and an external surface on said contact portion, a slit in said contact portion dividing said contact portion into a plurality of segments, a Belleville washer within said slit, and retaining means for retaining said Belleville washer within said slit.
Claim 9
Dependent Claim
39 words
An electrical connector as claimed in claim 6 wherein said Belleville washer has an aperture therethrough and said retaining means comprises a stud passing through said aperture, said stud being frictionally fixed within at least one of said segments.
Claim 10
Dependent Claim
73 words
An electrical connector as claimed in claim 6 wherein said male connector is normally oversize relative to said internal recess in said mating connector, said contact portion being capable of contracting against the outward force of said Belleville washer to a size which will fit into said internal recess, whereby said contact portion while disposed within said internal recess will have its external surface urged outwardly into intimate contact with said internal recess.
Claim 11
Dependent Claim
23 words
An electrical connector as claimed in claim 8 wherein a coating of silver is applied to said external surface of said contact portion.
