Abstract

PURPOSE: To prevent wear and tear caused by spark discharge and vibration by providing an insulating and abrasion-resisting collared bush in a movable joint part between a ear fitting and a ear for interrupting a shunt circuit of load current.
CONSTITUTION: To construct a collared bush 6, a bush part 8 with a collar 7 on the upper rim and a bush part 10 with a collar 9 on the lower rim sized by the inner diameter of the bush part 8 are prepared. For equipping an ear fitting 2, the part 8 is inserted from above to be supported by the collar 7, and glued and combined by adhesives with the part 10 inserted from the bottom in one body. This construction serves to prevent spark discharge, since an ear 3 and a nut 5 are perfectly insulated from the ear fitting 2 by the insulating and abrashion-resisting bush 6 to avoid the construction of a shunt circuit.
