Abstract

When two insulated fine wires have to be twisted together to achieve repeatable uniform twist and constant impedance, the guidance and tension of the single wires before twisting are of major importance to achieve this objective. Drawing A shows the wire twister. Drawing B is a cross section of the wire twister of Drawing A. A major problem encountered in the twisting of wires is the accumulation of dust and fiber particles from the wires in the wire guide openings constraining the free movement of the wires which result in a slow and steady increase in the wire tension. The accumulation of dust particles, however is not uniform for both wires and cause nonuniformity in the twisted wires.

Wire Twister

When two insulated fine wires have to be twisted together to achieve repeatable uniform twist and constant impedance, the guidance and tension of the single wires before twisting are of major importance to achieve this objective. Drawing A shows the wire twister. Drawing B is a cross section of the wire twister of Drawing A. A major problem encountered in the twisting of wires is the accumulation of dust and fiber particles from the wires in the wire guide openings constraining the free movement of the wires which result in a slow and steady increase in the wire tension. The accumulation of dust particles, however is not uniform for both wires and cause nonuniformity in the twisted wires. Since the fiber and dust particles can become firmly packed in the wire guides, a slight change in insulation thickness of the wire will also cause nonuniformity of the twisted wires. This wire guide replaces the tube or equivalent used in prior wire twisters, by a flexible member 2. The flexible member 2 as shown in Drawing B retains the wire 1 in the guides while allowing the wire to be passed by the flexible member without increasing the tension on the wire due to changes in insulation thickness. The flexible member 2 also allows dust and fiber particles to pass through the wire guides without affecting the tension on the wires to be twisted.
