Abstract
Abstract An adjustably sized laminar type telephone connector block suitable for interconnecting telephone subscriber pairs to telephone office switching equipment. The block comprises a plurality of superposed contact holding elements positioned between a pair of support elements, the support elements in turn having means for attachment to a main frame. The capacity of an individual block is varied by adding or removing contact holding elements. Each contact holding element includes pairs of interconnected quick clip contact elements of generally planar configuration which are separated from corresponding quick clip elements of adjacent contact holding elements by laterallly directed insulative flanges which overlie the quick clip contact elements, and which form strain relief means for conductors engaged upon the contact elements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
187 words
An improved telephone connector block for interconnecting individual subscriber pairs to central office equipment comprising: first and second elongated support elements, a plurality of generally planar contact holding elements positioned between said support elements in parallel juxtaposed relation, a plurality of contact elements supported upon each of said contact holding elements, and means interconnecting said support elements and contact holding elements in substantially congruent relation; said support elements having means for interconnecting said block to a telephone main frame; said contact holding elements having a principal axis and having first and second planar surfaces, one of said surfaces having a plurality of paired laterally extending recesses communicating with each other at inner ends thereof; said contact elements each including paired and interconnected quick clip terminals positioned within a corresponding pair of recesses; said contact holding elements, in juxtaposed relation, forming passages for accommodating conductors on either side thereof communicating with one of each of said pairs of laterally extending recesses, whereby outside subscriber pairs may be interconnected on one side of said block, and corresponding inside pairs may be interconnected on an opposite side of said block.
Claim 2
Dependent Claim
187 words
An improved telephone connector block for interconnecting individual subscriber pairs to central office equipment comprising: first and second elongated support elements, a plurality of generally planar contact holding elements positioned between said support elements in parallel juxtaposed relation, a plurality of contact elements supported upon each of said contact holding elements, and means interconnecting said support elements and contact holding elements in substantially congruent relation; said support elements having means for interconnecting said block to a telephone main frame; said contact holding elements having a principal axis and having first and second planar surfaces, one of said surfaces having a plurality of paired laterally extending recesses communicating with each other at inner ends thereof; said contact elements each including paired and interconnected quick clip terminals positioned within a corresponding pair of recesses; said contact holding elements, in juxtaposed relation, forming passages for accommodating conductors on either side thereof communicating with one of each of said pairs of laterally extending recesses, whereby outside subscriber pairs may be interconnected on one side of said block, and corresponding inside pairs may be interconnected on an opposite side of said block.
Claim 3
Dependent Claim
26 words
An improved telephone connector block in accordance with claim 1, further characterized in said pairs of quick clip connectors being oriented at a mutual right angle.
Claim 4
Dependent Claim
37 words
An improved telephone connector block in accordance with claim 1, further characterized in said quick clip connectors being separably interconnected and maintained in mutual interconnection by an interconnecting member having resilient means retaining said quick clip connectors.
Claim 5
Dependent Claim
56 words
An improved telephone connector block in accordance with claim 1, further characterized in said recesses in said contact holding elements substantially enclosing the entire length of said quick clip elements, and having openings therein corresponding to conductor retaining slots in said quick clip connectors wherein to provide a strain relief function relative to an engaged conductor.
