Abstract
Abstract Assembly for protecting telephone equipment from damage due to lightning or other high voltages on lines connected to the equipment. The assembly includes a housing comprising a base and a removable snap-on cover in which a plurality of protective devices are removably mounted in a plug-in manner. Each of the protective devices is mounted in a socket having a pair of contacts connected to external wire receiving terminals and a third contact connected to a ground buss. The cover is provided with a slotted opening which provides ventillation and permits observation of the protective devices.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
In an assembly for holding three-terminal gas-discharge devices for protecting telephone equipment from damage due to lightning or other high voltages on lines connected to the equipment: an insulative housing comprising a base and a cover removably mounted on the base, said housing being formed to include a plurality of sections in which the devices are mounted, contacts mounted in the base in each of the sections for engaging the terminals of the devices, wire receiving terminals connected electrically to two of the contacts in each section and extending externally of the housing for connection to the telephone equipment and lines, and an electrically conductive buss bar member mounted to the base and connected electrically to a third contact in each section.
Claim 2
Dependent Claim
122 words

Claim 3
Dependent Claim
23 words
The assembly of claim 1 further including releasable latch hooks extending between the cover and base for securing the cover to the base.
Claim 4
Dependent Claim
25 words
The assembly of claim 1 wherein the cover is formed to include an opening through which the protective devices are visible externally of the housing.
Claim 5
Dependent Claim
30 words
The assembly of claim 1 wherein the cover and base are elongated, and the sections in which the protective devices are mounted are longitudinally spaced and separated by transverse walls.
Claim 6
Dependent Claim
191 words
In an assembly for protecting telephone equipment from damage due to lightning or other high voltages on lines connected to the equipment: an elongated insulative housing comprising a base and a cover removably mounted on the base, said housing being formed to include a plurality of longitudinally spaced sections, a protective device removably mounted in each section of the housing, each protective device normally providing a circuit between first and second terminals of the same and being adapted for interrupting the circuit and providing a discharge path between one of the terminals and a third terminal in the event that the voltage between the one terminal and the third terminal reaches a predetermined level, first, second and third contacts mounted in the base in each of the sections and engaging respectively the first, second and third terminals of the protective device mounted therein, wire terminals connected electrically to the first and second contacts in each section and extending externally of the housing for connection to the telephone equipment and lines, and an electrically conductive buss bar member mounted to the base and connected electrically to the third contact in each section.
