TECHNICAL FIELD The present invention relates to the technical field of electrical engineering, and in particular to the design of flat bundles of electrical conductors.

Flat bundles of electrical conductors are most advantageous when utilized in vehicles or other machines such as machine tools, refrigeration equipment, etc. with multiple consumers of current supplied from a single power source. be.

BACKGROUND OF THE INVENTION In the technical field of electrical engineering, the use of flat bundles of electrical conductors has been known for a relatively long time. However, it is only within recent years that this flat bundle has found widespread use. This fact can be explained by the increasing number of objects having multiple consumers of power supplied from a single power source.

Flat bundles require lower costs when installed, have better conditions for cooling the conductors, and are easier to handle when pulling out one conductor tap from the entire bundle, thereby reducing the is known to meet the requirements of objects.

Two types of flat bundle designs are known in the art. In one type of bundle, the electrical conductors are bound to form a bundle by clamping their sides together in some way, for example by extrusion; in the other type, the electrical conductors are insulated. are placed parallel to each other and fixed by gluing, suturing or fusion to a flat base layer made in the form of a strip. The latter type of bundle design was by far the most popular because of the ease with which individual conductor taps could be pulled out of the bundle.

A flat bundle of electrical conductors (GB 1342716) formed by a plurality of insulated conductors and a clamping component is known in the art. The clamping component is a thermoplastic base layer in the form of a strip to which the electrical conductors forming the bundle are secured by fusing the conductor-insulating material to the base layer material.

an electrical conductor where the bundle includes the same main components but further comprises components fused to the base layer, said components being formed from thermoplastic and serving to tighten the bundle when installing it; A flat bundle of (USSR Patent No. 574048) is known in the art.

Although the flat bundles disclosed in the above-mentioned patents are advantageous, their use presents some difficulties.

Therefore, the thickness of the base layer is relatively thin, e.g.
mm, the flat bundle does not have adequate strength. The reason is that when applying mechanical forces to the conductor, the base layer is damaged.

Increasing the strength of the bundle by thickening the base layer inevitably results in a considerable increase in the material consumption of the bundle.

When supplying the bundle with components designed to tighten the bundle during the installation process, the need to perform individual tasks creates one problem. The reason is that when producing flat bundles with clamping components, it is necessary to prepare these clamping components separately and subsequently clamp them to the base layer of the bundle.

SUMMARY OF THE INVENTION It is an object of the present invention to form a bundle that is cheaper, more durable, consumes less material and, in addition, with the function of the electrical conductor of the bundle, compared to the bundles of the prior art. The object of the present invention is to provide a flat bundle of electrical conductors with lower material consumption by imparting to at least one conductor in the bundle the function of a component that clamps the remaining electrical conductors. .

The above object is a flat bundle of conductors formed by a plurality of insulated conductors and a clamping component, wherein the conductors are clamped to the flat surface of the clamping component. According to the invention, in a flat bundle of at least one electrical conductor, the clamping component is functionally part of the bundle and has a zigzag shape that staggers along said bundle. This is achieved by a flat bundle of conductors characterized in that it is formed by.

The flat bundle of the invention has high mechanical strength due to the fact that the strength of its clamping components is equal to the strength of the conductor represented by said components.

As one of the conductors in the bundle with a small difference (not more than 40%) between the length of the conductor placed in a staggered manner and their length relative to the length of the other conductors The use of two conductors results in lower material consumption and cost of the bundle.

The flat bundle of electrical conductors is preferably such that some Z-shaped top of the tottering-shaped electrical conductors extends beyond the limits of the extreme electrical conductors of the bundle and these electrical conductors are It is configured to form a loop with the body, which loop serves as a component for tightening the bundle to the installation location.

Such an arrangement of components for clamping the bundle does not require significant changes either in the design of the bundle at its clamping location or in the technology of its manufacture. Moreover, such a design eliminates the need to manufacture the mounting components separately, a consideration that, together with the considerations mentioned above, reduces the labor required for manufacturing the bundle and lowers the cost of materials. This results in the following result.

The invention will be further described with reference to the accompanying drawings.

[Brief explanation of the drawing]

In the accompanying drawings: FIG. 1 is a schematic representation of a flat bundle of the invention in the plane of the conductor arrangement; FIG. , depicting a flat bundle according to an embodiment of the invention; FIG. 3 is a cross-sectional view taken along line 3--3 of FIG. 2 showing the bundle being tightened into a mounting location;

DESCRIPTION OF THE PREFERRED EMBODIMENTS A flat bundle of conductors (FIG. 1) is formed by a plurality of insulated electrical conductors 1 and a clamping component 2, said electrical conductors 1 It is tightened to a solid surface. According to the invention, the clamping component 2 is formed by at least one electrical conductor 2 which is functionally part of the bundle and has a shape that wanders along the bundle.

Some Z of said tottering-shaped electrical conductors 2 extending beyond the limits of the electrical conductors 1' at the extreme end of the bundle
The tops 3 of the figures 4 (FIG. 2) together with these extreme conductors 1 form a loop 5, which serves to tighten the conductor bundle when it is installed. The bundle is tightened by means of a hook 6 arranged on the object 7 in which the bundle is utilized.
and by a pin 8 mounted in an opening provided in the object 7. The clamping of the conductors 1 and 1' to the conductor 2 can be accomplished by weaving or gluing with filaments, in the case of utilizing conductors with thermoplastic insulation.
This can be accomplished by fusing the insulator and conductor 2 to the insulator of conductors 1 and 1' at the contact points between them. An example of combining electrical conductors to form a bundle having a design according to the invention is shown below.

A clamping conductor is placed along the wobbling line on the surface of the conductor placed on a mold (not shown) in one plane, and said conductor is placed in a suitable position for laying the conductor. laid down by a device,
The clamping conductor moves progressively along the conductor-laying direction and at the same time reciprocates transversely to the conductor-laying direction. The conductors 2 lying in a tottering manner are pressed against the conductors lying parallel to each other, connecting one core of said conductor to one terminal of the high frequency generator, and connecting the remaining conductors 1 of the bundle, The conductive core wire of 1' is connected to the other terminal, and the toggle-shaped conductor described above is fused by radio frequency welding to the conductor placed on the mold.

Industrial Applicability The flat bundle of the above-described design is advantageous for use in objects having multiple consumers of power supplied from a single power source. It can be successfully employed in vehicles, refrigeration equipment, etc.
