In this case, the wedge-shaped protrusion 16 comes off from the split groove 8, and the split groove 8, which had been widening, becomes narrower, and the pair of terminal pins 1 become narrower.
The interval between 0 and 10 also becomes narrower and becomes almost parallel,
Since the terminal pin 10 and the terminal fitting 15 do not come into contact with each other or the contact pressure becomes extremely small, the terminal pin 10 and the terminal fitting 15 can be easily attached and detached, and sliding wear during attachment and detachment is extremely reduced. It is.

する効果を奏するのである。 As described above, the present invention provides an insulator with a groove at one end opening in the housing of an electrical device, provides terminal pins on both sides of the groove of the insulator, and connects a pair of terminals to one end of the power cord. In addition to providing a plug with a metal fitting, a wedge-shaped protrusion is formed between the terminal fittings of the plug, and the wedge-shaped protrusion and the split groove, and the terminal fitting and the terminal pin are respectively removably fitted. When attaching and detaching the terminal fitting, the contact pressure between the two becomes extremely small, making the operation easier and reducing sliding wear on both sides.Furthermore, when the terminal pin is fitted into the terminal fitting, the wedge-shaped protrusion prevents the terminal pin from tightening. is brought into pressure contact with the terminal fitting, thereby achieving the effect that the two are securely connected.
