Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal connecting section used for a power supply section of a motor or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a plate-shaped connection plate 2 is formed at the center of the end of a round bar-shaped conductor 1 in a supply portion of a power supply line connected to a terminal box of a motor. In many cases, a connector 4 in the form of a plate, which is a so-called vane board terminal, to which the cable 3 is connected, is tightened by bolts 5 and nuts 6 to be connected. Further, the connection portion is wound with a tape using an insulating tape 7 to insulate the connection portion.

[0003]

However, in this connection portion, there is a disadvantage that the bolt 5 tends to protrude outward on one side, and the workability of the insulation treatment is poor. Although a heat-shrinkable tube may be attached to the connection part instead of the insulating tape, the tube may be damaged because the tip of the bolt 5 projects outward.

An object of the present invention is to solve the above-mentioned drawbacks and to provide a terminal connecting portion designed so that a bolt does not protrude outward.

[0005]

In order to achieve the above object, a terminal connecting portion according to the present invention comprises a plate-shaped connecting plate protruding in the axial direction at the end of a conductor made of a round bar, and a cable end. The plate-shaped connector attached to the portion is brought into contact with the plate-shaped surfaces of each other and fastened and fixed with bolts and nuts, the fastening fixed portion is insulated, and the insulating portion is connected to the round bar conductor end. In a terminal connection portion which is proudly provided at the end of the cable, the plate-shaped connection plate of the round bar conductor abutting on the plate-shaped connector has an abutting surface substantially at the axis of the round bar conductor. It is characterized in that it is provided eccentrically with respect to the axis of the round bar conductor so as to be located at the top, and that its cross-sectional shape fits within the cross section of the round bar conductor.

[0006]

In the terminal connecting portion having the above-described structure, the bolt does not protrude outward even if the terminal plate is fastened by the bolt and nut because the connection plate is displaced from the center of the conductor.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS. FIG. 1 is a front view of a state in which a plate-shaped connection plate 12 is formed at the tip of a conductor 11 made of a round bar, and FIG. 2 is a side view. In this case, the base of the connection plate 12 is formed outside the center of the conductor 11, and a bolt hole 13 is provided at the center of the connection plate 12.

After connecting the electric wire 14 to the connecting plate 12 and attaching a plate-shaped connector 15 having a bolt hole (not shown) as shown in FIG. 3 and fastening with a bolt 16 and a nut 17, as shown in FIG. Insulation processing is performed by an insulating tape 18.

In this case, since the connecting plate 12 is deviated from the center of the conductor 11, even if the connecting member 15 is attached and tightened with the bolts 17 and the nuts 18, the connecting surface between the connecting plate 12 and the connecting member 15 is not conductive. 11, the bolt 16 will not protrude outward, and the problem described in the conventional example will not occur.

[0010]

As described above, the terminal connecting portion according to the present invention has a connection plate formed of a conductor at an eccentric position. Does not protrude outward,
The insulation processing section can be made smaller, and the terminal box containing these can be downsized, and the inter-phase insulation distance can be secured.
