Abstract
Abstract A protector module for use in mounting a gas tube arrester or carbon arrester assembly in a telephone central office protection system has an insulating base and a conductive case or cover. The base has a channel with a projecting stop on one side, in which channel is disposed a portion of a line contact. Another portion of the line contact extends through the base and is positioned against an upstanding wall located at one end on the other side of the base, in which side the gas tube arrester or carbon arrester assembly is disposed. The case is secured about the other side and the upstanding wall by a plurality of spherical projections on the base which lodge in holes in the case. When the case is so positioned on the base, a line electrode of the gas tube arrester or carbon arrester assembly makes electrical contact with the line contact and a ground electrode of the gas tube arrester or carbon arrester assembly is coupled to the case.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
121 words
A protector module for use in a protection system, said protector module comprising: an elongated insulating base having first and second elongated, opposing sides, said first side having a channel means therein and said second side having receiving surfaces, a line contact means disposed in said channel means and extending through said base to said second side, an arrester disposed on said receiving surfaces and having one electrode coupled to said line contact means and having another electrode, and a conductive case means disposed on said second side of said base such that said arrester is enclosed in a closed cavity formed by said base and said case means, said case means being coupled to said other electrode of said arrester.
Claim 2
Dependent Claim
121 words
A protector module for use in a protection system, said protector module comprising: an elongated insulating base having first and second elongated, opposing sides, said first side having a channel means therein and said second side having receiving surfaces, a line contact means disposed in said channel means and extending through said base to said second side, an arrester disposed on said receiving surfaces and having one electrode coupled to said line contact means and having another electrode, and a conductive case means disposed on said second side of said base such that said arrester is enclosed in a closed cavity formed by said base and said case means, said case means being coupled to said other electrode of said arrester.
Claim 3
Dependent Claim
50 words
The protector module as set forth in claim 1 wherein said channel means is formed by a pair of leg means extending from a support surface on said first side of said base and including a projecting stop at one end of said channel means projecting from said support surface.
Claim 4
Dependent Claim
38 words
The protector module as set forth in claim 1 wherein said arrester is positioned on said second side on said receiving surfaces by a spring means which at least partially couples said other electrode to said case means.
Claim 5
Dependent Claim
32 words
The protector module as set forth in claim 1 wherein said base has a generally flat support surface with said first and second sides being on opposite sides of said support surface.
Claim 6
Dependent Claim
92 words
The protector module as set forth in claim 1 wherein said case means has at least one flat elongated surface and wherein said arrester is a gas tube arrester having its other electrode coupled to said case means by a conductive spring means, said spring means positioning said gas tube arrester on said second side so that its one electrode is forced against said line contact means and having at least one generally flat portion positioned between and in contact with said other electrode and said flat surface of said case means.
Claim 7
Dependent Claim
71 words
The protector module as set forth in claim 1 wherein said arrester is a carbon arrester assembly having its other electrode coupled to said case means through a fusible pellet and a grounding basket or spring means and said line contact means has an electrode portion such that when said fusible pellet melts said grounding basket is forced against said electrode protector of said line contact means by said spring means.
Claim 8
Dependent Claim
127 words
A protector module for mounting an arrester having line and ground electrodes in a telephone protection system, said protector module comprising: an insulating base having a supporting surface with a channel along a first side of said supporting surface and a second side for said arrester, said base having a projecting stop extending from said first side at one end of said channel, contact means extending along said channel through said supporting surface to the second side of said base so as to be coupled to said line electrode of said arrester, and a conductive case means mounted on said second side such that said arrester is enclosed by said case means and said base, said case means being coupled to said ground electrode of said arrester.
Claim 9
Dependent Claim
127 words
A protector module for mounting an arrester having line and ground electrodes in a telephone protection system, said protector module comprising: an insulating base having a supporting surface with a channel along a first side of said supporting surface and a second side for said arrester, said base having a projecting stop extending from said first side at one end of said channel, contact means extending along said channel through said supporting surface to the second side of said base so as to be coupled to said line electrode of said arrester, and a conductive case means mounted on said second side such that said arrester is enclosed by said case means and said base, said case means being coupled to said ground electrode of said arrester.
Claim 10
Dependent Claim
44 words
The protector module as set forth in claim 7 wherein said base has spherical projection means along the opposed side edges and wherein said conductive case means has detent means in which said projection means are disposed when said case means encompasses said arrester.
