Abstract
Abstract A conductor terminal block and a mounting member therefor having provision for detachably holding one or more blocks snugly but detachably assembled to one or both faces of the mounting member. As shown, each block includes a pair of threaded studs to which conductors can be clamped. The one-piece mounting member is molded of resilient non-conductive material and includes a pair of resilient latches to which a respective terminal block can be snugly assembled. A tool serves to deflect the latches and release any block independently of the others. The conductor terminal connecting capacity is readily expandable upon need by adding one or more terminal blocks and one or more terminal block mounting members.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A terminal block having a foursided generally cubical main body of non-conductive material, a pair of threaded studs fixed thereto and projecting from one face thereof adjacent a respective diagonally related first pair of corners of said main body, a pair of openings through said main body positioned inwardly of the sides thereof and adjacent a diagonally related second pair of corners of said main body, said openings each having a detent surface below said one face and facing outwardly and adapted to seat a latching tang entering the opening from the face opposite said one face to hold said terminal block detachably assembled with said oppposite face snugly against a mounting member for said terminal block, and nut means on each of said threaded studs for holding a conductor assembled to each of said studs, said pair of studs and said pair of openings being symmetrically positioned on said one face such that said terminal block has the same mounting configuration when upside down whereby said terminal block may be mounted on said mounting member in a first upright position and in a second reversed position.
Claim 2
Dependent Claim
187 words
A terminal block having a foursided generally cubical main body of non-conductive material, a pair of threaded studs fixed thereto and projecting from one face thereof adjacent a respective diagonally related first pair of corners of said main body, a pair of openings through said main body positioned inwardly of the sides thereof and adjacent a diagonally related second pair of corners of said main body, said openings each having a detent surface below said one face and facing outwardly and adapted to seat a latching tang entering the opening from the face opposite said one face to hold said terminal block detachably assembled with said oppposite face snugly against a mounting member for said terminal block, and nut means on each of said threaded studs for holding a conductor assembled to each of said studs, said pair of studs and said pair of openings being symmetrically positioned on said one face such that said terminal block has the same mounting configuration when upside down whereby said terminal block may be mounted on said mounting member in a first upright position and in a second reversed position.
Claim 3
Dependent Claim
60 words
A terminal block as defined in claim 1 characterized in that the main body of said terminal block includes pairs of closely spaced L-shaped conductor keepers molded integral with said main body, said keepers being resilient and provided with hooked ends deflectable away from one another as a conductor is pressed therebetween and thereafter cooperating to hold the conductor captive.
Claim 4
Dependent Claim
35 words
A terminal block as defined in claim 2 characterized in that said main body is provided with separate pairs of said L-shaped keepers located close to the diametrically opposed sides of each of said studs.
