Abstract
Abstract A terminal block assembly wherein the electrical connection is broken, and the blocks are separated, by pivoting or rolling one block apart from the other. The terminal block assembly includes first and second terminal blocks, each block having one side adapted to engage and mate with one side on the other block. One edge on one block defines a roll axis. An opposing surface on the other (usually mounted) block defines a fulcrum. The fulcrum surface engages the roll axis when the one block is rolled or pivoted apart from the other block to pivot its mating side away from electrical connection with the other block.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
215 words
A roll-apart connect-disconnect terminal block assembly including separable first and second blocks, at least one first electrical contact means on one side of said first block, mating second contact means on one side of said second block for frictionally engaging said first contact means on said first block when said blocks are brought together, said one side of said first block having a recess configuration adapted to mate with a projection on said one side of said second block, said one side of said first block extending between two edges of said first block, one of said edges defining a roll axis, said one side of said second block extending between two edges and having marginal surface areas thereon adjacent one edge thereof between said edge and said projection, said surface areas defining a fulcrum surface which engages said one edge of said first block defining said roll axis when said blocks are in a fully engaged position, said edge and said surface remaining in contact when one of said blocks is pivoted with respect to said other block around said axis, said first and second contact means being moved in an arcuate path with respect to each other as they disengage as said first and second blocks are pivoted with respect to each other.
Claim 2
Dependent Claim
215 words
A roll-apart connect-disconnect terminal block assembly including separable first and second blocks, at least one first electrical contact means on one side of said first block, mating second contact means on one side of said second block for frictionally engaging said first contact means on said first block when said blocks are brought together, said one side of said first block having a recess configuration adapted to mate with a projection on said one side of said second block, said one side of said first block extending between two edges of said first block, one of said edges defining a roll axis, said one side of said second block extending between two edges and having marginal surface areas thereon adjacent one edge thereof between said edge and said projection, said surface areas defining a fulcrum surface which engages said one edge of said first block defining said roll axis when said blocks are in a fully engaged position, said edge and said surface remaining in contact when one of said blocks is pivoted with respect to said other block around said axis, said first and second contact means being moved in an arcuate path with respect to each other as they disengage as said first and second blocks are pivoted with respect to each other.
Claim 3
Dependent Claim
44 words
The assembly of claim 1 wherein said second block has at least one projection extending outwardly from said one side thereof and said first block has at least one mating recess in said one side thereof adapted to receive said at least one projection.
Claim 4
Dependent Claim
131 words
The assembly of claim 2 wherein said projection has a side wall which faces generally toward said one edge of said second block and which lies in a plane of said marginal surface area, said recess in said first block being defined in part by a side wall which extends into said one side of said first block along a line parallel to and spaced from said one edge and which forms an obtuse angle with said one side of said first block, the junction between said one side of said first block and said recess side wall along said line defining an edge of said recess which slidingly engages said side wall of said projection when one of said blocks is being rolled apart from the other of said blocks.
Claim 5
Dependent Claim
49 words
The assembly of claim 2 wherein said projection has a side wall which faces generally in a direction toward the other or second edge of the second block and which is slightly inclined, extending outwardly from said one side of said second block and inwardly from said second edge.
Claim 6
Dependent Claim
32 words
The assembly of claim 2 wherein said projection, viewing same in a direction parallel to said roll axis, has a generally trapezoidal cross section and said recess has a complementary cross section.
Claim 7
Dependent Claim
158 words
The assembly of claim 5 wherein said projection extends outwardly from said plane of said marginal surface areas and said trapezoidal cross section is defined by a first wall exTending outwardly from said plane from a line in said plane parallel to and spaced from said one edge and inwardly from said one edge thereby forming an obtuse angle with said plane, a top wall, and a second wall which extends outwardly from said plane and inwardly from said edge to said top wall from a line in said plane parallel to and spaced from the other or second edge of said second block and inwardly from said second edge thereby forming an obtuse angle with said plane which is smaller than said obtuse angle formed by said first wall and said marginal surface areas, the junction between said second wall and said top wall being rounded and said recess in said first block having a complementary configuration.
Claim 8
Dependent Claim
53 words
The assembly of claim 1 wherein one of said blocks has a guide pin extending from said one side thereof and said other block has a guide pin receiving opening in said one side thereof which is slightly larger than said guide pin and which is adapted to receive said guide pin therein.
Claim 9
Dependent Claim
42 words
The assembly of claim 2 wherein said projection has a blunt end defined by a top wall and has a rib extending from said top wall, and said recess has a bottom wall with a slot therein adapted to receive said rib.
