PURPOSE:To increase strength in the direction of rotation of a pin, and to reduce defective disconnection in an user for a transformer by forming a pressure- break section to a pin terminal and shaping a square-shaped hole section to a pin hole. CONSTITUTION:A pin hole 8 consisting of a circular hole section 8a and a square-shaped hole section 8b is formed to the lower end collar 2a of a spool 2 made of plastics. Pressure-break sections 7 and a pressure-break section 9 shaped to a section positioned at the square-shaped hole section 8b when a terminal pin 1 is pressed into the pin hole 8 are formed to the terminal pin 1. According to such constitution, structure, extremely resisting rotational stress is shaped similarly when the square-shaped pin terminal is pressed into the square- shaped pin hole. |
