Referring to fig. 1, an embodiment of the present application provides a composite conductor cable mechanism, including:

a first conductor 1, a plurality of the first conductors 1 being disposed at intermediate positions;

the second conductors 2 are uniformly distributed on the outer wall of the first conductor 1, and part of the second conductors 2 are in contact with the outer wall of the first conductor 1;

in the prior art, the conductive parts of most cables are made of pure copper or other single materials as the conductors of the cables, so that the weight and the manufacturing cost of the cables are high. In this document, the conductor is provided in two parts, a first conductor 1 and a second conductor 2. Specifically, the plurality of first conductors 1 are disposed at intermediate positions and have an axisymmetric structure, the plurality of second conductors 2 are disposed on outer walls of the plurality of first conductors 1, and portions of the plurality of second conductors 2 are in contact with the first conductors 1. Wherein the first conductor 1 and the second conductor 2 are cylindrical with equal diameters.

Preferably, the first conductors 1 form a first conductive layer and the second conductors 2 form a second conductive layer, the central axis of the first conductive layer and the central axis of the second conductive layer coinciding in the same direction of extension. So that the first conductive layer formed by the first conductor 1 and the second conductive layer formed by the second conductor 2 can be stably matched. More preferably, the cross section of the conductive portion formed by the first conductive layer and the second conductive layer is circular.

The arrangement is such that the conductor part is divided into a first conductor 1 and a second conductor 2, preferably, the first conductor 1 is made of pure copper, and the second conductor 2 is made of copper-clad aluminum, and the second conductor 2 can also be made of copper-clad magnesium, copper-clad aluminum-magnesium alloy and other materials. Such an arrangement allows the cable described in this application to maintain good electrical performance during use while reducing overall weight. Specifically, a plurality of pure copper monofilament first conductors 1 are placed in the middle, and a plurality of copper-clad aluminum magnesium alloy monofilament second conductors 2 are arranged around the first conductors 1. Preferably, the second conductor 2 is twisted around the first conductor 1, so that the first conductor 1 and the second conductor 2 can be integrated. So that the processing and the manufacturing are very convenient. And greatly reduces the production cost.

In one embodiment, the ratio of the thickness of the first conductive layer to the second conductive layer is 3. Specifically, the ratio of the diameter of the cross section of the first conductive layer formed by the first conductor 1 to the distance between the outermost wall and the innermost wall of the second conductive layer formed by the second conductor 2 is 3. It will be appreciated that such an arrangement enables the electrical performance of the cable to remain stable. In another embodiment of the present application, the first conductor 1 and the second conductor 2 are made of pure copper and copper-clad aluminum-magnesium alloy, respectively, and are combined with the structure in the present embodiment. Therefore, the overall conductivity of the cable can bear larger current on the basis of keeping stable, and meanwhile, the overall quality of the cable is reduced.

In one embodiment, the first conductive layer and the second conductive layer are twisted into a whole, and the cross-sectional area of the whole is 2.5-35 mm ² 。

In practice, the first conductive layer is twisted with the second conductive layer and forms one integral part, i.e. the conductive part of the cable. The cross-sectional area of the conductive part is set to 2.5-35 mm ² . Such an arrangement may allow the cable produced to be used in a variety of settings while maintaining good electrical conductivity.

In other embodiments of the present application, the first conductor 1 is made of pure copper, the second conductor 2 is made of copper-clad aluminum magnesium alloy, and the thickness ratio of the first conductive layer to the second conductive layer is 3. In contrast to the present embodiment, i.e. leadThe cross-sectional area of the electric part is set to be 2.5-35 mm ² And are arranged together. In production, the weight of the cable can be reduced while maintaining good conductive performance, and the difficulty of processing and transportation can be reduced, and at the same time, the cable having a conductive portion of such a structure can be applied to various environments.

Preferably, the surfaces of the first conductor 1 and the second conductor 2 are both subjected to smoothing treatment to reduce the abrasion of the contact part of the first conductor 1 and the second conductor 2. In the actual practice of the skilled worker, the first conductor 1 and the second conductor 2 of the conductive part of the cable are in direct contact by twisting. During transportation and during collision in use, the first conductor 1 and the second conductor 2 are subjected to a great deal of wear, which not only damages the internal structure of the cable, but also causes other injuries. For example, in the embodiment of the present application, the second conductor 2 is made of copper-clad aluminum magnesium alloy, and during continuous friction between the first conductor 1 and the second conductor 2, the structure of the copper-clad aluminum magnesium alloy may be damaged, so that the performance of the second conductor 2 is reduced, and this may cause the conductive performance of the cable to drop greatly, and may cause other situations that damage the cable. Therefore, the first conductor 1 and the second conductor 2 are smoothed, for example, polished, so that the abrasion of the outer surfaces of the first conductor 1 and the second conductor 2 when the contact friction is performed is reduced, and the service life of the cable and the safety and reliability when the cable is used can be prolonged.
