Abstract
Abstract A connector terminal is disclosed which comprises a base plate having an electrical contact portion at one side and an electrical wire connecting portion at the other side, and a pair of wire barrel members extending upwardly from both edges of the base plate so that a conductor of an electrical wire is crimped by the pair of wire barrel members. A CH CW ratio in the electrical wire pressure contact portion is in the range of 31 to 35%, the CH CW ratio being defined by the following equation: <IMAGE> where CH is the crimp height and CW is the crimp width.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
A connector terminal comprising a base plate having an electrical contact portion at one side and an electrical wire connecting portion at the other side, and a pair of wire barrel members initially extending upwardly from both edges of said base plate, a conductor of an electrical wire being subsequently crimped by said pair of wire barrel members, wherein a CH.CW ratio of an electrical wire pressure contact portion formed by said base plate and said wire barrel members after crimping is in the range of 31 to 35%, said CH.CW ratio being defined by the following equation: ##EQU4## where CH is the crimp height and CW is the crimp width.
Claim 2
Dependent Claim
111 words
A connector terminal comprising a base plate having an electrical contact portion at one side and an electrical wire connecting portion at the other side, and a pair of wire barrel members initially extending upwardly from both edges of said base plate, a conductor of an electrical wire being subsequently crimped by said pair of wire barrel members, wherein a CH.CW ratio of an electrical wire pressure contact portion formed by said base plate and said wire barrel members after crimping is in the range of 31 to 35%, said CH.CW ratio being defined by the following equation: ##EQU4## where CH is the crimp height and CW is the crimp width.
Claim 3
Dependent Claim
22 words
The connector terminal according to claim 1 further comprising another pair of barrel members for crimping a coating of said electrical wire.
Claim 4
Dependent Claim
21 words
