[Also in Group XXXVI] Jointing by stamping.-A method of making an electrical connection between a ferrule of an electrical connector 10 and a conductor 12 lying within the ferrule comprises simultaneously cold forging the ferrule and conductor together over two axially spaced and peripherally confined bands so that longitudinal extrusion of metal within the bands takes place into the zone between the bands to form a peripheral bead around the connection. Dies for carrying out the method comprise a die nest 20 and a male die 22 both having spaced working surfaces 24 which in the forging operation apply cold forging pressure to three areas symmetrically spaced around the conductor 12 to produce two axially spaced forged joints 36 of triangular cross-section with an interposed bulged portion 40 (Figs. 2 and 4). Specification 811,996 is referred to.
