Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A tool for inserting a forked contact having prongs with upwardly converging outer surfaces and inwardly directed contact surfaces into an aperture in a circuit board, said tool comprising a body with a cavity for receiving said prongs, said cavity being partially defined by upwardly converging inner surfaces shaped to mate with said upwardly converging outer surfaces of said prongs to prevent said prongs from bending outwardly from each other and being damaged during insertion of said contact into a circuit board, said cavity also being defined by insertion force bearing surfaces for transmitting insertion forces to upper portions of said prongs, said cavity being open between said prongs below said contact surfaces.
Claim 2
Dependent Claim
113 words
A tool for inserting a forked contact having prongs with upwardly converging outer surfaces and inwardly directed contact surfaces into an aperture in a circuit board, said tool comprising a body with a cavity for receiving said prongs, said cavity being partially defined by upwardly converging inner surfaces shaped to mate with said upwardly converging outer surfaces of said prongs to prevent said prongs from bending outwardly from each other and being damaged during insertion of said contact into a circuit board, said cavity also being defined by insertion force bearing surfaces for transmitting insertion forces to upper portions of said prongs, said cavity being open between said prongs below said contact surfaces.
Claim 3
Dependent Claim
37 words
The tool of claim 1 wherein said contact prongs include upwardly diverging inner surfaces, and wherein said insertion force bearing surfaces comprise upwardly diverging surfaces shaped to mate with said upwardly diverging inner surfaces of said prongs.
Claim 4
Dependent Claim
13 words
The tool of claim 2 wherein said body is made of plastic material.
Claim 5
Dependent Claim
30 words
The tool of claim 1 wherein said body has an upper portion with an upwardly converging surface above a cut-out portion, to facilitate removal of the tool from the contact.
Claim 6
Dependent Claim
13 words
The tool of claim 1 wherein there are a plurality of said cavities.
Claim 7
Dependent Claim
104 words
A tool for inserting a forked contact having prongs with outer surfaces and inwardly directed contact surfaces into an aperture in a circuit board, said tool comprising a body with a cavity for receiving said prongs, said cavity being partially defined by inner surfaces shaped to mate with said outer surfaces of said prongs to prevent said prongs from bending outwardly from each other and being damaged during insertion into a circuit board, said cavity also being defined by insertion force bearing surfaces for transmitting insertion forces to upper portions of said prongs, said cavity being open between said prongs below said contact surfaces.
Claim 8
Dependent Claim
104 words
A tool for inserting a forked contact having prongs with outer surfaces and inwardly directed contact surfaces into an aperture in a circuit board, said tool comprising a body with a cavity for receiving said prongs, said cavity being partially defined by inner surfaces shaped to mate with said outer surfaces of said prongs to prevent said prongs from bending outwardly from each other and being damaged during insertion into a circuit board, said cavity also being defined by insertion force bearing surfaces for transmitting insertion forces to upper portions of said prongs, said cavity being open between said prongs below said contact surfaces.
