Therefore, the caulked portion 11 of the terminal 10 and the wire connection terminal 2 to which the terminal 10 is attached are individually covered and protected with a soft insulating material. Furthermore, the terminal 10 can be tightened at any position around the axis of the tip 3 of the wire connection terminal 2.
The longitudinal tightening direction of the terminal 10, which is orthogonal to the axis of the terminal 10, is not restricted.

[Problem that the invention attempts to solve]

However, as vehicle auxiliary parts are installed in the engine room and as vehicles become front-wheel drive and engines become more powerful, the mounting positions of vehicle auxiliary parts are often closer to engine parts and piping, and the electrical wiring connected to the wire connection terminal 2 is becoming more and more difficult. Since only a specific space can be used for mounting the terminal 10, it has become necessary to always restrict the tightening direction of the terminal 10 to a fixed direction.

For this reason, the conventional electric wire connecting device cannot regulate the direction in which the terminal 10 is tightened, so there is a problem in that it cannot comply with the regulation of the direction in which the terminal 10 is tightened.

Therefore, an object of the present invention is to make it possible to reliably regulate the tightening direction of a terminal to be tightened to a wire connection terminal with a simple structure.

[Means for solving problems]

Therefore, the present invention is characterized in that the mounting direction of the wire connection terminal and the cover that protects the terminal is restricted.

Specifically, the anti-rotation terminal cover device of the present invention connects one end of an electric wire to an electric wire connection terminal provided outside the case in order to conduct electrical wiring to vehicle auxiliary parts such as a starter and an alternator. A wire connecting device comprising a terminal connected to the wire connecting terminal, the wire connecting device comprising: a bush made of an insulating material and having a flat surface formed on at least a part of the outer circumferential surface, which covers the wire connecting terminal except for its tip; one of its open ends is fitted onto the outer periphery of the bush in the same shape, and a cover is attached to the other of the open ends so that the open end can be opened and closed;
A body formed to cover the electric wire connection terminal, and a shape that covers the connection part corresponding to a position where the connection part with the electric wire of the terminal connected to the electric wire connection terminal extends together with the electric wire, It is characterized by comprising an envelope part that is integrally formed on the outer periphery of the body part and is divided in the axial direction of the body part, one of which is a cover.

[Effect]

The protective cover has a body and a wrapper formed integrally, the wire connecting terminal is attached to the body, and the terminal and one end of the wire are gripped and covered by the wrapper. .

In this case, one of the open ends of the cylindrical body is fitted onto the outer circumferential surface of the bush so as to be non-rotatable.

Therefore, by fitting one of the open ends of the body into the bushing so that the direction of the envelope matches the tightening direction of the terminal, the protective cover will not rotate around the axis of the wire connection terminal. Since the terminal is fixed to the terminal, the tightening direction of the terminal can always be restricted to a constant direction. In this state, tighten the terminal to the tip of the wire connection terminal and close the cover provided on the body.
