Abstract
Abstract A housing for a telephone line protector comprises a well in which are positioned two spring biased members. A first spring biased member is adjacent to the back end of the well and biased away therefrom. The second spring biased member is axially aligned with and biased away from the first spring biased member. One line conductor is connected to the first spring biased member and the other line conductor is connected to a terminal at the back end. The spring bias of the second spring biased member is stronger than the bias of the first spring biased member. Insertion of a protector module first causes movement of the first spring biased member to contact the terminal at the back end, and then moves the second spring biased member relative to the first spring biased member. The protector module contacts a ground connection at the front end of the well as it is inserted.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
189 words
A telephone line protector housing comprising: a housing defining a well having front and back ends; a ground connection at said front end, said ground connection at said front end including a threaded bore for reception of a threaded protector module into said well; a cable conductor attachment and a line conductor attachment each connected to the housing; a first member in said well, said first member being adjacent to and spring biased away from said back end; a second member in said well, said second member being adjacent to and spring biased away from said first member, the spring bias on the second member being stronger than the spring bias on the first member; means for connecting a line conductor to said first and second members via said line conductor attachment; and means for connecting a cable conductor to said first member via said cable conductor attachment, whereby, upon initial insertion of said protector module, said module contacts and moves said second member which sequentially moves said first member into contact with said means for connecting said cable conductor, and further insertion further moves said second member only.
Claim 2
Dependent Claim
189 words
A telephone line protector housing comprising: a housing defining a well having front and back ends; a ground connection at said front end, said ground connection at said front end including a threaded bore for reception of a threaded protector module into said well; a cable conductor attachment and a line conductor attachment each connected to the housing; a first member in said well, said first member being adjacent to and spring biased away from said back end; a second member in said well, said second member being adjacent to and spring biased away from said first member, the spring bias on the second member being stronger than the spring bias on the first member; means for connecting a line conductor to said first and second members via said line conductor attachment; and means for connecting a cable conductor to said first member via said cable conductor attachment, whereby, upon initial insertion of said protector module, said module contacts and moves said second member which sequentially moves said first member into contact with said means for connecting said cable conductor, and further insertion further moves said second member only.
Claim 3
Dependent Claim
38 words
A protector housing as claimed in claim 1, wherein said first spring biased member comprises a first metal disc-like member and a compression spring extending between the disc-like member and an insulating abutment member at said back end.
Claim 4
Dependent Claim
24 words
A protector housing as claimed in claim 2, said abutment member including a metal annular member, a terminal attached to said metal annular member.
Claim 5
Dependent Claim
34 words
A protector housing as claimed in claim 3, wherein said second spring biased member comprises a second metal disc-like member and a compression spring extending between said disc-like member and said metal annular member.
Claim 6
Dependent Claim
35 words
A protector housing as claimed in claim 3, wherein said terminal includes an electrically conducting member extending through said abutment member and having a front end positioned for contact with said first metal disc-like member.
Claim 7
Independent Claim
176 words
A method of protecting a telephone line via a protector housing, comprising the steps of: forming a well in said housing, said well having front and back ends; attaching a ground connection to said front end, said ground connection having a threaded bore for receiving a threaded protector module; connecting a line conductor attachment to said housing; connecting a cable conductor attachment to said housing; inserting a first spring in said well; inserting a first member in said well on said first spring; inserting a second spring stronger than said first spring in said well on said first member; inserting a second member in said well on said second spring; interconnecting the line conductor attachment and the first and second members; interconnecting the cable conductor attachment with a pin mounted adjacent to the first member; inserting said protector module in said threaded bore against said second member, first compressing said first spring whereby said first disc contacts said pin, and whereby further inserting of said protector module compresses said second spring and moves said second member.
Claim 8
