Abstract: A splice head for use with a modular wire connector, to work with and hold the wires while installing them in the connector, particularly for wires of differing diameters. The splice head includes a coil spring loosely arranged on a bar and movable axially thereon. By selecting an appropriate location for the starting point on the spring and selection of the spring position on the bar, different sized wires can be fixed by the coils of the spring. The bar may be circular in cross-section to allow the spring to slide easily forward and backward. This construction allows simpler placement of the wires since the coil spring does not need to to replaced for wires of different sizes, and there is no requirement that the splicing operation begin at one particular end of the coil since neither end is fixed.

Abstract: Flexible retaining tongues are formed within a cable receiving passageway of a basic body, the tongues retaining the cable therebetween, and being resiliently deformed upon insertion of the cable whereby an effective strain relief is achieved concurrently.

Abstract: A wire holding device for locating wires in an electrical connector, comprising at least one passageway into which a connection wire to be held can be moved essentially normally of its length through an outwardly enlarging entrance slot toward a closed end of the passageway. A first barb adapted to be resiliently urged aside by a wire upon the introduction thereof extends from a sidewall of the passageway adjacent the entrance slot. A second barb extends from the sidewall opposite the first barb and is adapted to be resiliently urged aside by the wire upon the introduction thereof, the free end of the second barb, together with the closed end of the passageway partitioning off a partial passageway.

Abstract: An electrical connector having a hollow cylindrical contact element with two circumferential wire connecting slots. A cap rotatable about the contact element and has a transverse channel for receiving an insulated wire end to carry it into a first of the wire connecting slots upon rotation of the cap. A tubular sleeve is also rotatable about the contact element and has a transverse channel for receiving an insulated wire end to carry it into the second wire connecting slot upon rotation of the tubular sleeve. A locking mechanism locks the tubular sleeve after rotation to its wire connecting position.

Abstract: A method for cleaning an exposed bundle of cable ends of multi conductor transmission cable, especially grease filled telephone cables, in which one places the bundle of cable ends, preferably after separation and/or rough cleaning, into a cleaning fluid-containing manually kneadable, flexible pouch, the open end of the pouch is sealed around the cable and a forceful cleaning action is obtained by kneading the pouch around the cable ends. After sufficient interaction time, the bundle is removed from the cleaning pouch and the cable ends are preferably wiped with a cloth.
