Abstract
Abstract An overvoltage surge protector and housing for telephone communication lines to protect equipment connected thereto includes an insulated housing having one terminal disposed therein which is adapted to be connected to earth ground and a second terminal disposed in a removable assembly which includes the means for connection to the communication line as an integral part thereof. The overvoltage surge protector device is adapted to be retained within the second terminal and, when removed for replacement by a service technician, requires that the communication line affixed to the terminal be removed from the terminal in order to remove the protector device, thus requiring the communication lines to be reconnected when the defective protective device is removed and/or replaced.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
136 words
An overvoltage surge protector housing for protecting communication lines and equipment connected thereto from voltage surges comprising: (a) a housing of insulating material having at least one well-type aperture disposed therein; (b) a first terminal adapted to be connected to earth ground; (c) a first electrode portion disposed at the closed end of said well-type aperture having a generally centrally disposed upwardly extending portion, said first electrode being connected to said first terminal, and (d) a second terminal removably received within the open end of said well-type aperture having a second electrode portion and means integral with said electrode portion for connection to one of said communication lines, said second terminal including protector means retained therein and adapted to be in intimate contact with said first and second electrode portions when disposed in said well-type aperture.
Claim 2
Dependent Claim
136 words
An overvoltage surge protector housing for protecting communication lines and equipment connected thereto from voltage surges comprising: (a) a housing of insulating material having at least one well-type aperture disposed therein; (b) a first terminal adapted to be connected to earth ground; (c) a first electrode portion disposed at the closed end of said well-type aperture having a generally centrally disposed upwardly extending portion, said first electrode being connected to said first terminal, and (d) a second terminal removably received within the open end of said well-type aperture having a second electrode portion and means integral with said electrode portion for connection to one of said communication lines, said second terminal including protector means retained therein and adapted to be in intimate contact with said first and second electrode portions when disposed in said well-type aperture.
Claim 3
Dependent Claim
34 words
An overvoltage surge protector housing according to claim 1 wherein said second terminal is provided with an externally threaded portion for cooperating with internal threads provided proximate the open end of said well-type aperture.
Claim 4
Dependent Claim
31 words
An overvoltage surge protector housing according to claim 2 wherein said housing, said second terminal threaded portion and said internal threads of said well-type aperture are fabricated from an insulating material.
Claim 5
Dependent Claim
17 words
An overvoltage surge protector housing according to claim 1 wherein said protector means is a gas tube.
Claim 6
Dependent Claim
22 words
An overvoltage surge protector housing according to claims 1 or 3 wherein said protector means is readily replaceable in said second terminal.
Claim 7
Dependent Claim
22 words
An overvoltage surge protector housing according to claims 1 or 3 wherein said protector means is permanently affixed in said second terminal.
Claim 8
Dependent Claim
35 words
An overvoltage surge protector housing according to claim 1 wherein said means for connection to one of said communication lines is a threaded stud and cooperating nut for receiving said communication line for affixment thereon.
Claim 9
Dependent Claim
37 words
An overvoltage surge protector housing according to claim 1 wherein said first electrode portion includes an electrically conductive link extending to an externally disposed threaded stud having a cooperating nut thereon for receiving said earth ground connection.
Claim 10
Dependent Claim
47 words
An overvoltage surge protector housing according to claims 1, 2, 3, 4 or 8 wherein said second electrode portion and said means integral with said electrode portion for connecting to one of said communication lines are disposed in generally coaxial alignment with said first electrode extending portion.
Claim 11
Dependent Claim
30 words
An overvoltage surge protector housing according to claim 8 wherein said first electrode portion further includes spring means for insuring intimate contact between said first electrode and said protective means.
Claim 12
Dependent Claim
45 words
An overvoltage surge protector housing according to claim 10 wherein said spring means provides an electrically conductive path between said first electrode portion and said second electrode portion when said second terminal is inserted within said well-like aperture without a protective means being disposed therein.
Claim 13
Dependent Claim
27 words
An overvoltage surge protector according to claim 1 or 3 wherein said protector means is permanently affixed in said second terminal to provide an environmentally sealed assembly.
Claim 14
Dependent Claim
24 words
An overvoltage surge protector according to claim 1 wherein said protector means is removably held within said second terminal by means of a cage.
