Abstract: A family of connectors is described for splicing, half-tapping, bridging and terminating multiple insulated wires. The connectors are particularly suitable to telephone central office applications requiring limited numbers of conductor reconnections. The basic connector consists of a mandrel around which the wires of a wire group are looped, a mandrel holder which retains the wires in loop-around configuration; and a contact module containing double-ended split beam contacts. Physical connection between wires mounted on two mandrels is made by inserting the mandrels into respective holders; and then mounting the two resulting assemblies on respective sides of a contact module. Advantageously, each mandrel holder may be double-sided to receive two mandrels. Correspondingly, the contact module may be designed to mount double-sided mandrel holders. A stack consisting of mandrels in their holders alternating between contact modules can provide for multiple appearances of wires in a given wire set.
