| 摘要 | A conductor with a loose-fitting insulating jacket and having terminal loops pressed therefrom through its insulation by a punch operating from the side opposite the protrusion. The wire is pulled bodily relative to its own insulation as the loop is formed to avoid wire drawing and reduction in cross section of the wire. The insulating jackets of a plurality of wires may be joined in flat, edge relation to form a multiple-wire flat ribbon cable and the loops formed in groups repeated longitudinally of the cable, with the loops in each group extending upwardly at right angles to the plane of the cable and longitudinally and transversely spaced in a staggered pattern. The immediately preceding loop in a wire or cable is used as an anchoring point in the pressing out of a new spaced loop so that the wire is bodily slid within its insulating jacket from the direction in which the newly formed loop is offset from the previously formed loop. | ||||||
| 权利要求 | 2. The method defined in claim 1, including: consecutively forming said loops at spaced intervals along the length of the wire while always sliding the wire from the same end by anchoring each immediately previously formed loop while the next succeeding loop is being pressed out. 3. The method defined in claim 1, including: joining together a plurality of said wires into a multiple-wire, flat ribbon cable prior to the pressing out of the terminal loops therefrom; and forming said loops in groups spaced longitudinally of the cable and with the terminal loops in each group formed simultaneously in longitudinally and transversely spaced relation in a staggered pattern. 4. The metHod of forming an insulated conductor with at least one bare terminal loop comprising: providing a wire conductor with a loose-fitting insulating surrounding layer within which said wire is movable; and pressing a terminal loop from said wire out through its insulation by punch means moving transversely of the wire from the side opposite the direction of protrusion while pulling the material for the loop by moving the wire within its insulation so as to avoid wire drawing and reduction of cross section. 5. The method defined in claim 4, including: consecutively forming a plurality of said loops at spaced intervals along the length of the wire while always sliding the wire from the same end by anchoring each immediately previously formed loop while the next succeeding loop is being pressed out. 6. The method defined in claim 4 including: joining insulated wire conductors into flat cable prior to the pressing out of any terminal loops therefrom. 7. The method defined in claim 4 including: joining insulated wire conductors into flat ribbon cable prior to the pressing out of any terminal loops therefrom; and thereafter, forming a plurality of loops in groups spaced longitudinally of the cable and with the terminal loops in each group formed simultaneously in spaced relation. |
