Abstract
Abstract A tool (10) for fitting a conductor terminating receptacle (11) on a spade lug terminal (12) of an electrical component (16). The tool (10) comprises a circular rod (21) one end of which is formed to present a tab (23) cut along a chord of the cross-section of the rod (21) having an inner surface (24) tangent to a hole (22) formed into the rod (21) from its end coaxial with its longitudinal axis. The rolled conductor contact section (19) of a receptacle is inserted in the end hole (22), the conductor (20) extending outside of the hole (22) through a slot (25) in the side of the rod (21) along the depth of the hole (22). The receptacle (11) is clasped between the extended tab (23) which bears on the rear face (28) of the receptacle (11) and a pair of short lugs (26, 27) extending from the end of the rod (21) on either side of the slot (25), which lugs either fit into the folded over sides (17, 18) of the receptacle or bear against their ends.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
213 words
A tool for fitting a conductor receptacle to a spade lug terminal, said receptacle having a pair of folded over sides for receiving the sides of said terminal, each folded over side defining in part an axially extending recess, and a conductor contact section folded about said conductor, the end of said conductor extending substantially parallel to said folded over sides, said tool comprising a rod having a hole formed therein from one end coaxial with its longitudinal axis, said hole receiving the folded conductor contact section of said receptacle, said one end of said rod further having a slot formed therein to said hole parallel to said longitudinal axis, said slot admitting said conductor, a tab extending beyond said one end of said rod having a surface substantially tangent to the inner surface of said hole, said tab bearing on one side of said receptacle when said folded conductor contact section of said receptacle is fitted into said hole, and a pair of lugs extending beyond said one end of said rod on respective opposite sides of said slot, said lugs fitting within respective ones of the axially extending recesses of said folded over sides, of said receptacle when said folded conductor contact section of said receptacle is fitted into said hole.
Claim 2
Dependent Claim
213 words
A tool for fitting a conductor receptacle to a spade lug terminal, said receptacle having a pair of folded over sides for receiving the sides of said terminal, each folded over side defining in part an axially extending recess, and a conductor contact section folded about said conductor, the end of said conductor extending substantially parallel to said folded over sides, said tool comprising a rod having a hole formed therein from one end coaxial with its longitudinal axis, said hole receiving the folded conductor contact section of said receptacle, said one end of said rod further having a slot formed therein to said hole parallel to said longitudinal axis, said slot admitting said conductor, a tab extending beyond said one end of said rod having a surface substantially tangent to the inner surface of said hole, said tab bearing on one side of said receptacle when said folded conductor contact section of said receptacle is fitted into said hole, and a pair of lugs extending beyond said one end of said rod on respective opposite sides of said slot, said lugs fitting within respective ones of the axially extending recesses of said folded over sides, of said receptacle when said folded conductor contact section of said receptacle is fitted into said hole.
Claim 3
Dependent Claim
42 words
A tool as claimed in claim 1 in which said pair of lugs are dimensioned and positioned to fit within said folded over sides, respectively, of said receptacle when said folded conductor contact section of said receptacle is fitted into said hole.
Claim 4
Dependent Claim
