<p>PURPOSE:To protect a jumper wire from abrasion or damage, by placing a spacer within a predetermined range at the end of a spiral rod when the spiral rod is wound around the jumper wire. CONSTITUTION:When a spiral rod 2 is wound around a jumper wire 1, a spacer 6 is placed near the end of the spiral rod 2. When winding pitch of the spiral rod 2 is P, the spacer 6 is detachably attached within a range l<=P/4 from the tip of the spiral rod 2. Preferably, a groove section 6a for containing the spiral rod 2 is made in the spacer 6. Since the tip of the spiral rod 2 does not rub the surface of the jumper wire 1 directly, the jumper wire 1 can be protected from abrasion or damage.</p> |
