Abstract
Abstract A terminal block for high voltage electrical leads includes a plurality of individual housings into which the terminated leads are received. The housings in turn are pluggably received within cavities of a plurality of modular terminal blocks which are stacked together and interlocked, and which are further mounted along a track. A locking bar partially overlies the cavities in the terminal block preventing removal of the individual housings. The locking bar is resiliently and removably latched to end plates mounted in the track and receiving therebetween the stacked terminal blocks.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A locking bar assembly, comprising: a channel shaped track, a plurality of dielectric blocks serially arranged along said track, a plurality of electrical leads terminated with corresponding electrical contacts, a pair of plates receiving therebetween said plurality of blocks, said plates having mutually aligned notch portions, dielectric housings having enlarged forward portions receiving said contacts and rearward portions of reduced cross-section from which said leads protrude, said blocks having cavities pluggably receiving corresponding forward portions of said housings therein with said rearward portions protruding from said cavities, a locking bar having resiliently flexible opposed flanges, said opposed flanges being resiliently compressed toward each other and thereby latchably received in a corresponding notch portion of each said plate, and said bar partially overlying said cavities of said blocks preventing withdrawal of said enlarged portions of said housings from said cavities.
Claim 2
Dependent Claim
139 words
A locking bar assembly, comprising: a channel shaped track, a plurality of dielectric blocks serially arranged along said track, a plurality of electrical leads terminated with corresponding electrical contacts, a pair of plates receiving therebetween said plurality of blocks, said plates having mutually aligned notch portions, dielectric housings having enlarged forward portions receiving said contacts and rearward portions of reduced cross-section from which said leads protrude, said blocks having cavities pluggably receiving corresponding forward portions of said housings therein with said rearward portions protruding from said cavities, a locking bar having resiliently flexible opposed flanges, said opposed flanges being resiliently compressed toward each other and thereby latchably received in a corresponding notch portion of each said plate, and said bar partially overlying said cavities of said blocks preventing withdrawal of said enlarged portions of said housings from said cavities.
Claim 3
Dependent Claim
42 words
The structure as recited in claim 1, wherein, said flange portions are provided with raised lip portions received within said notch portions, and said notch portions are provided with opposed projecting teeth preventing withdrawal of said lip portions from said notch portions.
Claim 4
Dependent Claim
23 words
The structure as recited in claim 2, wherein, said flange portions are chamfered for wedged entry past said teeth into said notch portions.
