Abstract

An electrical connector including a contact member for connection to an outer stranded conductor of a coaxial cable having an inner conductor and a dielectric separating the inner conductor from the outer stranded conductor, the contact member including a pair of spaced sidewalls interconnected by a base to define a generally U-shaped ferrule, a lance formed from each sidewall and extending inwardly of the sidewall at an acute angle in a direction away from the base, the lances being positioned opposite each other and, when the ferrule is crimped about the coaxial cable, each lance piercing and passing between the strands of the outer stranded conductor so that some of the strands are positioned between a lance and an inner surface of a sidewall.

Claims

1. An electrical connector including a contact member for connection to an outer stranded conductor of a coaxial cable having an inner conductor and a dielectric separating the inner conductor from the outer stranded conductor, the contact member including a pair of spaced sidewalls interconnected by a base to define a generally U-shaped ferrule, a lance formed from each said sidewall and extending inwardly of the sidewall at an acute angle in a direction away from the base with the free ends of the lances being more closely spaced than the distance between the lances at the points where they are connected to the sidewalls, the lances being positioned directly opposite each other with the distance between the lance free ends being less than the outside dimension of the cable outer stranded conductor and, when the ferrule is crimped about the coaxial cable, each lance piercing and passing between the strands of the outer stranded conductor so that some of the strands are positioned between a lance and an inner surface of a sidewall.

2. An electrical connector as claimed in claim 1, in which the contact member has a contact part in the form of a pin integral with the ferrule, the pin extending forwardly of the ferrule but laterally offset with respect to the ferrule axis.

3. An electrical connection between an electrical connector and an outer stranded conductor of a coaxial cable having an inner conductor and a dielectric separating the inner conductor from the outer stranded conductor, the electrical connector including a contact member having a ferrule including a pair of spaced sidewalls crimped about the outer stranded conductoR and a lance formed from each sidewall, each lance extending inwardly of the sidewall and piercing and passing between the strands of the outer stranded conductor so that some of the strands are positioned between a lance and an inner surface of a sidewall.

4. An electrical connection as claimed in claim 3 in which an outer insulating sheath encloses the outer stranded conductor the ferrule being crimped about the outer insulation sheath and each lance piercing the sheath prior to piercing and passing between the strands of the outer stranded conductor.
