Abstract
Abstract A one-piece dielectric terminal cap having a generally rectangular tapered bore with a wide mouth opening for accepting a distorted two prong edge-to-edge terminal and restoring it substantially to its initial position. The cap also includes means for probe testing the terminal without removal of the cap from the terminal, plus tool engaging means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
204 words
A one-piece dielectric terminal straightening cap adapted for use with terminals in a terminal wiring block, said cap including a one-piece body having a double tapered generally rectangular bore opening through one end thereof and terminating short of the opposite end, said cap including front, back and side walls forming said bore, the said walls forming said bore being tapered for a substantial portion of their extent relative to two perpendicular planes lying on the axis of said bore, said front, back and side walls forming a wide double tapered throat having a relatively large included angle between opposite wall which blends into a lower included angle portion of said bore, said lower included angle portion having a substantially greater axial extent than said wide tapered throat and terminates in a rectangular bore having substantially parallel opposed walls for the substantial remaining portion of said bore, the transfer measurement between opposite walls of said rectangular bore being substantially equal to the corresponding complementary cross-sectional measurements of the terminal adapted to be covered by said cap, whereby a two-blade terminal that has been distorted by introduction of wires therebetween is adapted to be returned to its initial position and better contact with said wires insured.
Claim 2
Dependent Claim
204 words
A one-piece dielectric terminal straightening cap adapted for use with terminals in a terminal wiring block, said cap including a one-piece body having a double tapered generally rectangular bore opening through one end thereof and terminating short of the opposite end, said cap including front, back and side walls forming said bore, the said walls forming said bore being tapered for a substantial portion of their extent relative to two perpendicular planes lying on the axis of said bore, said front, back and side walls forming a wide double tapered throat having a relatively large included angle between opposite wall which blends into a lower included angle portion of said bore, said lower included angle portion having a substantially greater axial extent than said wide tapered throat and terminates in a rectangular bore having substantially parallel opposed walls for the substantial remaining portion of said bore, the transfer measurement between opposite walls of said rectangular bore being substantially equal to the corresponding complementary cross-sectional measurements of the terminal adapted to be covered by said cap, whereby a two-blade terminal that has been distorted by introduction of wires therebetween is adapted to be returned to its initial position and better contact with said wires insured.
Claim 3
Dependent Claim
50 words
A terminal cap of the type claimed in claim 1 wherein said rectangular bore is terminated at said opposite end by a transverse wall having a central aperture therein which communicates with said bore to permit introduction of a test probe to contact said terminal without removal of said cap.
Claim 4
Dependent Claim
31 words
A terminal cap of the type claimed in claim 2 wherein the exterior of said cap is provided at said opposite end with groove means to permit gripping by tool means.
Claim 5
Dependent Claim
23 words
A terminal cap of the type claimed in claim 3 wherein said groove means are longitudinally disposed on the front and back walls.
Claim 6
Dependent Claim
17 words
A terminal cap of the claimed in claim 1 wherein said cap is provided with indicia means.
