Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure in which one terminal is connected to another terminal by bolting, and an object thereof is to improve conductive performance and prevent heat generation at a contact surface.

[0002]

2. Description of the Related Art A connection structure combining a convex V-shaped terminal and a corresponding concave V-shaped terminal is known from Japanese Utility Model Laid-Open Publication No. 56-99767. After tightening both terminals with bolts on the center line of the V-shaped angle, the other side bolts eccentric to the eccentricity are tightened on both sides of the concave V-shaped terminal.

[0003]

The wedge-shaped pushing of the convex V-shaped terminal may cause both walls of the concave V-shaped terminal to be elastically deformed, thereby causing a gap opening between the convex V-shaped terminal and the convex V-shaped terminal. Although this is adjusted by tightening with a cross bolt, the structure is unreasonable, and it is difficult to stably obtain good adhesion.

[0004]

According to the present invention, the tightening bolts of both terminals are limited to one direction, and the thrust in the center line direction at the center of both contact surfaces is parallel to the center line of the V-shape. It works at the appropriate position on the top, and both fit well and the concave V
There is no room for gaps due to the opening of the profile.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. The terminal 1 having the convex V-shaped surface and the terminal 2 having the concave V-shaped surface can be in close contact with each other on the V-shaped surface, and a bolt hole 1a formed in the center of each opposed inclined surface.
2a, and tighten them with bolts 3 and 3 penetrating. The bolt holes are all parallel and symmetrically inclined with respect to the left and right inclined surfaces. Although the terminal 1 has a slight cutout 1b at the convex end to prevent contact with the concave bottom of the terminal 2, a groove 2b may be provided at the concave bottom if necessary. Wire B is connected to terminal 1,
The terminal 2 is fixed to the device A via the other end flat portion 2c.

[0006]

As the bolt 3 is tightened, the uneven terminals rub against each other by slightly moving the inclined surface within the gap between the bolt and the bolt hole, thereby increasing the surface smoothness. In addition, even when firmly tightened, there is no danger that the contact surfaces of both the concave and convex will fit easily and produce an open gap between them. A stable conductive action can be achieved for a long time.
