Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
A controlled feeder block for electrically connecting a first wire to either a second wire or a wire receiving terminal comprising: an insulative block, first and second contact elements mounted in said insulative block, said first and second contact elements being constructed for electrical connection to first and second wires, respectively, a terminal post adapted to slide between a first position and a second position within said insulative block said terminal post carrying in electrical isolation, a terminal conductor electrically connected to a said wire receiving terminal and a bridging conductor, said bridging conductor making electrical contact with both said first and second contact elements when said terminal post is in said first position, and said terminal conductor making electrical contact with said first contact element when said terminal post is in said second position.
Claim 2
Dependent Claim
135 words
A controlled feeder block for electrically connecting a first wire to either a second wire or a wire receiving terminal comprising: an insulative block, first and second contact elements mounted in said insulative block, said first and second contact elements being constructed for electrical connection to first and second wires, respectively, a terminal post adapted to slide between a first position and a second position within said insulative block said terminal post carrying in electrical isolation, a terminal conductor electrically connected to a said wire receiving terminal and a bridging conductor, said bridging conductor making electrical contact with both said first and second contact elements when said terminal post is in said first position, and said terminal conductor making electrical contact with said first contact element when said terminal post is in said second position.
Claim 3
Dependent Claim
110 words
The controlled feeder block of claim 1, wherein each of said contact elements has a bifurcated portion forming a pair of arms, said arms having opposed edges defining a slot, said slot having a narrow entry portion for resiliently receiving a conductor into electrical contact, and a wide throat portion adapted to receive a conductor without establishing electrical contact between said conductor and said contact element, and wherein said bridging conductor makes electrical contact in the entry portion of each contact element when said terminal post is in said first position and slides into the throat of the contact element upon movement of said terminal post to said second position.
Claim 4
Dependent Claim
23 words
The controlled feeder block of claim 1, wherein said insulative block has a plurality of said terminal posts arranged in rows and columns.
Claim 5
Dependent Claim
23 words
The controlled feeder block of claim 1, wherein said wire receiving terminal is formed by a binding post screw onto said terminal post.
Claim 6
Dependent Claim
35 words
The controlled feeder block of claim 1, wherein said terminal post assembly is formed as an insulative terminal post base attached to a conductive terminal post which is threaded to receive a binding post screw.
Claim 7
Dependent Claim
38 words
The controlled feeder block of claim 1, further including detent means to prevent the sliding of said terminal post between its first and second positions unless a force of a predetermined magnitude is applied to said terminal post.
