Abstract
Abstract An improved telephone subscriber circuit protector module particularly suited for use in interconnecting with protector blocks having exposed quick clip terminals on an exposed surface thereof. The module features a relatively few number of metallic parts, and can be assembled with a series of simple hand operations. A three-element gas tube is employed in which the contacts are formed with elongated extensions, the extensions providing interconnections with contacts in such manner as to maintain the contacts in operative position when the module is assembled.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
190 words
An improved subscriber circuit protector module for use with quick clip type telephone connector blocks comprising: a base element having a quick clip receiving recess therein, a cover element partially overlying said base element, a plurality of elongated quick clip contact elements at least partially surrounding said base element and resiliently maintained thereon, said contact elements having a resilient arm thereon extending into said quick clip retaining recess in said base element and defining a resilient opening in a base portion thereof; said base element having a second recess therein, a ground contact element secured within said recess and having resilient openings therein in aligned relation relative to said openings in said clip contact elements; at least one three-element gas tube having elongated electrodes extending radially from a principal axis thereof, said electrodes each penetrating an opening in one of said clip contact elements and an opening in said ground contact element to establish electrical communication from said quick clip contact element to said ground contact element, said ground contact element having a free end thereon extending outwardly of said base element for communicating with a source of ground potential.
Claim 2
Dependent Claim
190 words
An improved subscriber circuit protector module for use with quick clip type telephone connector blocks comprising: a base element having a quick clip receiving recess therein, a cover element partially overlying said base element, a plurality of elongated quick clip contact elements at least partially surrounding said base element and resiliently maintained thereon, said contact elements having a resilient arm thereon extending into said quick clip retaining recess in said base element and defining a resilient opening in a base portion thereof; said base element having a second recess therein, a ground contact element secured within said recess and having resilient openings therein in aligned relation relative to said openings in said clip contact elements; at least one three-element gas tube having elongated electrodes extending radially from a principal axis thereof, said electrodes each penetrating an opening in one of said clip contact elements and an opening in said ground contact element to establish electrical communication from said quick clip contact element to said ground contact element, said ground contact element having a free end thereon extending outwardly of said base element for communicating with a source of ground potential.
Claim 3
Dependent Claim
24 words
A protector module in accordance with claim 1, further characterized in said ground contact element being secured to said base element by rivet means.
Claim 4
Dependent Claim
47 words
A protector module in accordance with claim 1, further characterized in said cover element defining an enclosed cavity with said base element having inner surfaces bearing upon the electrodes of said gas tube element and serving to maintain said electrodes in contact with said clip contact elements.
