Abstract
Abstract An electrical connector made from sheet material which includes a portion for connection to a flat conductor of a flat flexible cable. The connection portion includes a base and a platform spaced from but overlying the base. The platform has a lance so that on crimping the connecting portion to a flat flexible cable operatively positioned between the platform and the base, the lance pierces the cable and operatively engages a flat conductor.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
An electrical contact made from a sheet metal blank comprising a portion for connection to a flat conductor of a flat, flexible cable, the connection portion including a base of double thickness, a first layer of the base having a through aperture in alignment with an embossment formed in the second layer of the base, the embossment presenting a concave surface towards the aperture and a platform spaced from but overlying the first layer, the platform having a lance in alignment with the aperture, so that on crimping the connection portion to a flat, flexible cable operatively positioned between the platform and the base, the lance pierces the cable and passes through the aperture to engage the concave surface of the embossment which deflexes the lance laterally and inhibits withdrawal of the lance through the aperturE.
Claim 2
Dependent Claim
136 words
An electrical contact made from a sheet metal blank comprising a portion for connection to a flat conductor of a flat, flexible cable, the connection portion including a base of double thickness, a first layer of the base having a through aperture in alignment with an embossment formed in the second layer of the base, the embossment presenting a concave surface towards the aperture and a platform spaced from but overlying the first layer, the platform having a lance in alignment with the aperture, so that on crimping the connection portion to a flat, flexible cable operatively positioned between the platform and the base, the lance pierces the cable and passes through the aperture to engage the concave surface of the embossment which deflexes the lance laterally and inhibits withdrawal of the lance through the aperturE.
Claim 3
Dependent Claim
49 words
An electrical contact as claimed in claim 1, in which the base of double thickness is formed by folding the connection portion along a line extending from a front end to an opposite rear end of the connection portion, the first and second layers being of generally equal width.
Claim 4
Dependent Claim
31 words
An electrical contact as claimed in claim 1, in which the platform is of the same width as the layers and is joined to the front end of the first layer.
Claim 5
Dependent Claim
33 words
An electrical contact as claimed in claim 1, in which the contact portion is joined to the front end of the second layer and is of the same width as the second layer.
Claim 6
Dependent Claim
43 words
An electrical contact as claimed in claim 1, in which two spaced lances are provided on the platform, each of which lances is in alignment with an aperture in the first layer, the embossment being elongate and extending to cover the spaced apertures.
