Abstract
Abstract A connector for a coaxial cable comprises a single stamping having four equally spaced branches 1 to 4 and defining a central aperture 5. Each branch 1 to 4 has spring clip portions 6 at its free end and wing portions 8. To attach the connector the outer conductor of the cable, which consists of a plurality of parallel strands, is stripped of insulation. The strands revealed are split into four groups 11 which are laid in the four branches 1 to 4 and the wing portions 8 closed over them while the central conductor 12 of the cable is pushed through the aperture 5. The branches 1 to 4 are then folded through 90° so that their end edges form the sides of a square and their spring clip portions 6 can receive the four spades of a complementary connector part which surround a central socket for the reception of the central conductor 12. The connector may have more or less than four branches and the branches may be individual connectors.
