Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
An electrical contact made from sheet material having a part for connection to a flat conductor of a flat, flexible cable, the part comprising first and second arms arranged in spaced, opposed relationship, the arms being relatively movable towards each other for crimp connection to a flat conductor of the cable, the first arm having an embossment in the form of a dome, the apex of the dome having a through aperture, the second arm having a lance extending towards and in alignment with the aperture so that on crimping, the lance initially pierces the cable and passes through the aperture, subsequent crimping pressure causing the embossment to flatten with a consequent reduction in area of the aperture, the sides of which aperture grip the lance and inhibit withdrawal of the lance from the aperture.
Claim 2
Dependent Claim
135 words

Claim 3
Dependent Claim
49 words
An electrical connector as claimed in claim 1, in which two lances are provided on the second arm and two complementary domes are provided on the first arm, each dome having a convex surface extending towards the second arm, the apex of each dome having an elongate through aperture.
Claim 4
Dependent Claim
53 words
An electrical connector as claimed in claim 1, in which two lances are provided on the second arm and two complementary domes are provided on the first arm, each dome having a convex surface extending towards the second arm the apex of the dome being flattened and having a circular cross-section through aperture.
