Description

[Detailed description of the invention] [Technical field to which the invention pertains] This invention relates to supporting electric appliances such as transformers, particularly conductors whose capacity is less than medium capacity and whose size is relatively small.

[Prior art and its problems]

Figures 1 to 3 are structural diagrams of a support 2 for a conventional transformer conductor 1, in which the conductor 1 led out from the winding 3 is fixed between clamps 2a and 2b made of oil wood, etc., and is further supported. It is supported from the frame 4 by the piece 2c. However, the conventional structure of this type has the disadvantage that not only the oilwood is expensive, but also the number of parts is large and assembly time is required, making it even more expensive.

[Purpose of invention]

The purpose of this invention is to correct the above-mentioned conventional drawbacks and provide a conductor support for electrical appliances that is simple in structure, easy to assemble, and inexpensive.

[Key points of the idea]

According to the configuration of this invention, the above object is achieved as follows. That is, it is made of a flexible insulating plate that is bent in two, and is provided with a groove that opens at the bent edge, and after storing the conductor to be supported in the groove, a presser is placed between the conductor and the inside of the bent edge. Insert the rod and lock the conductor in the groove.

[Example of idea]

Figures 4 to 6 are examples of this invention.
A front view, a side view, and a plan view of the support 41 of the conductor 1 led out from the winding 3 are shown, respectively. Support 41
is a flexible insulating plate made of press board or insulating paper, for example, with a thickness of about 2 mm, which is bent in two, and has a groove 42 that opens at the bent edge 41a.
is provided, and after the conductor 1 to be supported is accommodated in this groove, a presser bar 43 is inserted between the conductor 1 and the inside of the bent edge 41a to lock the conductor 1 in the groove 42.

The end opposite the bent edge 41a of the support 41 is fixed to the frame 4 with a bolt or the like. FIG. 7 is a developed view of the support 41.

FIGS. 8 and 9 show other embodiments of this invention, in which the cross section of the presser bar 81 is formed such that the diameter from its central axis to its outer periphery changes depending on its position in the circumferential direction.
For example, if the conductor 1 is formed into an elliptical cross-section as shown in the figure and inserted between the inner side of the bent edge 41a of the conductor 1 and the support 41 with the short diameter of the presser bar 81 facing, the insertion can be easily made, and after insertion, it can be rotated at right angles. By doing so, the conductor 1 can be securely fixed. In this case, if the tip of the longer diameter of the presser bar 81 is cut off on a plane parallel to the shorter axis, the position of the presser bar will be stabilized after the rotation is fixed. FIG. 10 is a sectional view of a presser bar 90 according to another embodiment of the present invention, in which the material is a round bar and a part 91 or two parts, ie, a part opposing this, are cut off in a plane parallel to the axis. The effect in this case is similar to that shown in the previous figure, and has the advantage of simplifying the work.

[Effect of idea]

As is clear from the above explanation, the configuration of this invention has a simple structure with fewer parts, is easy to assemble, and uses an inexpensive insulating plate, making it possible to obtain a more inexpensive conductor support for electrical appliances.
