PURPOSE:To fix electronic components such as a resistor and a capacitor efficiently by making a fixation shaft, which is tapered towards the top and has step-shaped irregular sections and planes, and a terminal piece having claws fitted to the irregular sections. CONSTITUTION:An approximately cylindrical fixation shaft 1 has irregular sections 2 and planes 3. The irregular sections 2 are formed on the shaft 1 except for its planes 3, the shaft 1 is tapered towards the top, with D1<D2, and a plurality of curved sections 2a and flat sections 2b are formed in step form on the tapered faces. The tip of a terminal piece 6 fitted to the shaft 1 is approximately ring-shaped and two semicircular claws 7 to be fitted on the sections 2 are formed on the inner wall of the ring and always energized inside. When fitted to the shaft 1, the piece 6 is inserted from the tip 4 of the shaft 1 and locked at the specified steps of the sections 2 by the contraction of the springs of the claws 7. When unlocked, the piece 6 is turned by 90 deg.. Thereby the piece is locked and unlocked in one step and components are fixed more efficiently. |
