業性が低下することはない。That is, according to the connection structure of the high voltage electric wire in this embodiment, the terminal fitting portion 3 of the connection terminal 2 for the high voltage electric wire.
Because the entire outer peripheral surface of the tubular body portion 3a is in pressure contact with the inner peripheral surface of the socket fitting 21 in a surface contact state, the spring piece 56 of the conventional high-voltage wire connection terminal 52 shown in FIG. It is difficult for the contact pressure to drop. Further, the cylindrical body portion 3a is elastically deformed in the radial direction after the tip abutting portion 5 abuts on the bottom surface 21a of the socket fitting 21 and is further pushed in. There is almost no insertion resistance of the terminal fitting portion 3 which is set so as to be loosely fitted to the inner peripheral surface of the socket fitting 21 until it abuts on 21a, and the work of attaching the insulating cap 1 to the high voltage tower portion 20 is performed. There is no decrease in sex.
