Abstract
Abstract A hand-held tool for the convenient attachment and disconnection of conductors to individual insulation displacement terminals on a telephone connector block. The device includes a first member for serially inserting the free end of a conductor into a resiliently expandable slot in the terminal, and severing the end of the wire which projects from the slot at a predetermined length. A second remotely positioned member provides for the engagement of the conductor for removal of an unwanted connection. The last-mentioned member also includes structure for the engagement of a protector module overlying the terminal for purposes of removal of the same to gain access to the conductor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
In a tool for removing an engaged wire conductor from a slot in an insulation displacement terminal, the tool including a manually engageable handle element and a wire removal element having a free end projecting from said handle element, said wire removal element having hook-like means for engaging said conductor, the improvement comprising: said wire removal element being of generally U-shaped cross section and forming a base wall and a pair of parallel side walls extending to a free end thereof, said hook-like means being located in at least one of said side walls; said base wall being longitudinally shorter than said side walls to form an elongated slot between said side walls; whereby said side walls are adapted to engage an enlargement on a protector module overlying said insulation displacement terminal to facilitate removal therefrom to gain access to said insulation displacement terminal.
Claim 2
Dependent Claim
144 words
In a tool for removing an engaged wire conductor from a slot in an insulation displacement terminal, the tool including a manually engageable handle element and a wire removal element having a free end projecting from said handle element, said wire removal element having hook-like means for engaging said conductor, the improvement comprising: said wire removal element being of generally U-shaped cross section and forming a base wall and a pair of parallel side walls extending to a free end thereof, said hook-like means being located in at least one of said side walls; said base wall being longitudinally shorter than said side walls to form an elongated slot between said side walls; whereby said side walls are adapted to engage an enlargement on a protector module overlying said insulation displacement terminal to facilitate removal therefrom to gain access to said insulation displacement terminal.
Claim 3
Dependent Claim
176 words
In a combination of telephone connector block having projecting insulation displacement terminals extending therefrom, a protector module resiliently engaging said insulation displacement terminals to effect electrical communication therebetween, and a tool for installing and removing conductors in engagement with said insulation displacement terminals, said protector module having an outer surface mounting an engageable handle including an enlargement on an end thereof, the improvement comprising: said tool having a wire removal element on one end thereof of generally U-shaped cross section to include a base wall and a pair of parallel side walls, wire-engaging hook like means formed in at least one side wall adjacent a free end thereof, said base wall being shorter in longitudinal length than that of said side walls to form an elongated slot between said side walls of width less than the width of said enlargement on said handle; whereby said enlargement may be selectively slidably engaged within said slot to facilitate removal of said protector module from engagement with corresponding insulation displacement terminals to enable access to said insulation displacement terminals.
Claim 4
Dependent Claim
