Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
210 words
In a connection apparatus having a terminal block of nonconducting material with a terminal block contact of conducting material attached thereto, said terminal block contact having a channel therethrough and at least two positions for receiving conductors and having clamp means for clamping said conductors to said terminal block contact at each position for receiving conductors, the improvement which comprises: a contoured clamp pad not connected to said clamp means and having a surface conforming to the shape of a nonflat conductor for disposition between said clamp means and such nonflat conductor for transmitting clamping pressure from said clamping means to the surface of such a nonflat conductor, said contoured clamp pad being sized to fit within said channel and extend over only a first portion of the length of the channel so that a second portion of the terminal block contact can be used for a flat conductor; and two flat connection plates sized to fit within said channel and extend over the length thereof and adapted so that a flat conductor can be clamped between the plates in the second portion of the channel, the flat connection plates being positioned so that the non-flat conductor can be clamped between the contoured clamp pad and one of the plates.
Claim 2
Dependent Claim
210 words
In a connection apparatus having a terminal block of nonconducting material with a terminal block contact of conducting material attached thereto, said terminal block contact having a channel therethrough and at least two positions for receiving conductors and having clamp means for clamping said conductors to said terminal block contact at each position for receiving conductors, the improvement which comprises: a contoured clamp pad not connected to said clamp means and having a surface conforming to the shape of a nonflat conductor for disposition between said clamp means and such nonflat conductor for transmitting clamping pressure from said clamping means to the surface of such a nonflat conductor, said contoured clamp pad being sized to fit within said channel and extend over only a first portion of the length of the channel so that a second portion of the terminal block contact can be used for a flat conductor; and two flat connection plates sized to fit within said channel and extend over the length thereof and adapted so that a flat conductor can be clamped between the plates in the second portion of the channel, the flat connection plates being positioned so that the non-flat conductor can be clamped between the contoured clamp pad and one of the plates.
Claim 3
Dependent Claim
85 words
An apparatus as defined in claim 1, wherein said terminal block contact comprises a slot through to said hollow channel and perpendicular to the axis of said channel, said terminal block contact having a shoulder extending through said slot into said channel, and wherein each of said flat connection plates has a groove therein disposed to engage said shoulder for retention of said flat connection plates in said channel when said clamp means is not clamping said flat connection plates to said terminal block contact.
Claim 4
Dependent Claim
14 words
An apparatus as defined in claim 2 wherein said channel is rectangular in cross-section.
