A composite connector for use with a circuit board is formed from a folded sheet metal preform and has, at one end, a socket in which a terminal pin of a circuit component can be resiliently gripped and, at the other end, a tubular end portion including two bifurcated contacts for displacing the insulating covering of an insulated wire when it is introduced between their limbs. The longitudinally extending free edges of the folded preform in the socket are circumferentially spaced with respect to the longitudinally extending free edges of the folded preform in the tubular end portion. Integral resilient tongues in the socket for effecting electrical contact with a terminal pin of a circuit component are circumferentially spaced with respect to the slots bounded by the limbs of the bifurcated contacts.

Circuit board composite connector

In a bandoleer of composite insulation displacement connectors, the tubular end portion of each composite connector incorporating diametrically opposed bifurcated insulation displacement contacts is joined to a side edge of a metal strip by a fracturable link so folded out of the plane of the strip that the common axis of the slots of the bifurcated contacts lies at an acute angle to the longitudinal axis of the strip. This acute angle is such that, when composite connectors are fitted into adjacent holes in a circuit board, the positions of the bifurcated contacts of each composite connector are such that a length of insulated conductor introduced between the limbs of the bifurcated contacts of the composite connector will extend between neighboring composite connectors with negligible risk of rendering difficult connection of a length of insulated conductor to a neighboring composite connector.

Circuit board composite connectors

A composite connector for use with a perforated circuit board is formed from a preform of electrically conductive sheet metal which is folded to form, at one end of the composite connector, a socket which will make a snap fit in a hole in a circuit board and in which a terminal pin of a circuit component can be resiliently gripped and, at the other end of the composite connector, two bifurcated contacts. The bifurcated contacts are transversely spaced apart and are of such a form that when a length of insulated wire is introduced between the limbs of each bifurcated contact, the limbs will cut through the insulating covering of the wire to effect an electrical connection with the wire at two positions spaced along its length.
