Abstract
Abstract A ground contact strip for use in a current tap comprises an elongated planar member having at least one D shaped arcuate loop integrally formed at a front end with the vertical arm of said D loop movably positioned within a slot in said planar member, with the vertical arm of said D loop having an inwardly extending projection for coacting with a ground plug inserted into said loop, and a front D shaped loop of the same configuration integrally formed near the other end of said planar member for also receiving a ground plug of either a U shaped or round configuration.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
188 words
In a current tap of the type comprising a molded body having a first pair of parallel plug receivable openings in one side of said body, second and third pairs of parallel plug receivable openings in the opposite side of said body, a ground connection opening adjacent each of said pair of parallel plug receivable openings, a pair of parallel contact strips disposed in said body in adjacent relationship to said pairs of parallel plug receivable openings, the combination therewith of a ground contact strip comprising: a generally planar strip disposed between said contact strips and including first and second D shaped loop receptacles each underlying one of said ground connection openings associated with said first and second pair of receivable openings, and having an arcuate front portion terminating at a location spaced from said strip and an arm extending toward said strip, said strip further including first and second slots in said strip, each said slot being adjacent the end of one of said arms for receiving the same to allow each said arm to move when a ground plug is inserted into said associated ground opening.
Claim 2
Dependent Claim
188 words
In a current tap of the type comprising a molded body having a first pair of parallel plug receivable openings in one side of said body, second and third pairs of parallel plug receivable openings in the opposite side of said body, a ground connection opening adjacent each of said pair of parallel plug receivable openings, a pair of parallel contact strips disposed in said body in adjacent relationship to said pairs of parallel plug receivable openings, the combination therewith of a ground contact strip comprising: a generally planar strip disposed between said contact strips and including first and second D shaped loop receptacles each underlying one of said ground connection openings associated with said first and second pair of receivable openings, and having an arcuate front portion terminating at a location spaced from said strip and an arm extending toward said strip, said strip further including first and second slots in said strip, each said slot being adjacent the end of one of said arms for receiving the same to allow each said arm to move when a ground plug is inserted into said associated ground opening.
Claim 3
Dependent Claim
42 words
The combination and ground contact strip according to claim 1 wherein each of said arms of said D shaped loops has a projection extending inwardly towards said arcuate front portion of said D configuration for assuring contact with a round ground plug.
Claim 4
Dependent Claim
24 words
The combination and ground contact strip according to claim 1 wherein said first and second D shaped loops are mirror images of each other.
Claim 5
Dependent Claim
94 words
The combination and ground contact strip according to claim 1 further including: a third D shaped loop receptacle on said planar strip and underlying said ground connection opening associated with said third pair of receivable openings, with said third D shaped loop receptacle of the same configuration as said first and second, wherein the end of the arm thereof extends toward a third slot in said strip adjacent the end of said arm for receiving the same to allow said arm to move when a ground plug is inserted into said associated ground opening.
Claim 6
Dependent Claim
36 words
The combination and ground contact strip according to claim 4 further including: a U shaped channel formed at the end of said planar strip closest to said third D shaped loop for receiving a ground wire.
Claim 7
Dependent Claim
21 words
The combination and contact strip according to claim 1 wherein said planar strip is integrally formed with said D shaped loops.
Claim 8
Dependent Claim
17 words
The combination and contact strip according to claim 1 wherein said planar strip is fabricated from brass.
Claim 9
Dependent Claim
54 words
The combination and contact strip according to claim 5 wherein said planar strip has a first planar section extending in a first plane from said channel and then in a second plane in a central region containing said third D shaped loop and then in said first plane towards said first and second loops.
Claim 10
Dependent Claim
21 words
The combination and contact strip according to claim 1 wherein said ground plug has a round or U shaped cross section.
Claim 11
Dependent Claim
125 words
A current tap comprising a pair of plug receivable openings with a ground connection opening adjacent thereto, a pair of contacts in adjacent relationship to said pair of plug receivable openings, and a ground contact means in adjacent relationship to ground connection opening, wherein: said ground contact means includes a generally planar strip; said generally planar strip includes a D shaped loop receptacle underlying said ground connection opening and having an arcuate front portion terminating at a location spaced from said strip and an arm extending toward said strip; and said generally planar strip further includes a slot therein adjacent the end of said arm for receiving the same to allow said arm to move when a ground plug is inserted into said ground opening.
Claim 12
Dependent Claim
125 words
A current tap comprising a pair of plug receivable openings with a ground connection opening adjacent thereto, a pair of contacts in adjacent relationship to said pair of plug receivable openings, and a ground contact means in adjacent relationship to ground connection opening, wherein: said ground contact means includes a generally planar strip; said generally planar strip includes a D shaped loop receptacle underlying said ground connection opening and having an arcuate front portion terminating at a location spaced from said strip and an arm extending toward said strip; and said generally planar strip further includes a slot therein adjacent the end of said arm for receiving the same to allow said arm to move when a ground plug is inserted into said ground opening.
