Description

Wire with molded wire core

Technical Field

The utility model relates to the technical field of wires and cables, in particular to a wire with a molded wire core.

Background

At present, the existing common electric wires on the market are all formed into core conductors by round copper wires, and for electric wires with slightly higher power, two problems exist: 1. if a single conductor is used, such as the electric wire shown in fig. 1, the electric wire is hard due to the large area of the single core 1', which causes inconvenience in use; 2. by using a plurality of branch cores 2' as shown in fig. 2, because the cross section of each branch core 2' is circular, useless cavity gaps are formed between the cores 2', so that the external dimension of the external insulating sheath material is increased to cause the waste of the insulating sheath material, and meanwhile, due to the existence of the cavity, one of the thin cores 2' is bent in the cavity gaps when being bent, and certain core 2' displacement as shown in fig. 3 is caused to deform the cross section of the whole electric wire.

Disclosure of utility model

The utility model aims to solve the technical problems that: the utility model provides a wire of molded line sinle silk, it is harder and stranded circular separated time core easily takes place the displacement and easily takes place the problem of tortuous in inside to overcome current single sinle silk.

The technical scheme adopted for solving the technical problems is as follows: the electric wire with the molded line core comprises a conductive line core and an insulating sleeve wrapping the line core, wherein the cross section of the line core is regular hexagon, and the line core is formed by bundling six line splitting cores with the same shape and size and regular triangle cross section. The molded line core of the utility model is a regular hexagonal line core with a shape different from that of a common line core, and each branching line core forming the line core is a regular triangular line.

Specifically, the outside of the electric wire insulation sleeve is also sleeved with a protective sleeve.

Specifically, the wire core is a copper wire, an aluminum wire or an aluminum alloy wire.

Specifically, the wire core is formed by helically twisting six wire cores.

The beneficial effects of the utility model are as follows: the utility model comprises six line cores with regular triangle cross sections, each line core is stably clustered together, no cavity is generated in the interior, the curvature is better than that of the existing single line core electric wire, the consumption of external wrapping materials is saved compared with the existing multiple line core electric wires, and the line cores are not easy to displace and bend.

Detailed Description

The following describes the technical scheme in the embodiment of the present utility model in detail with reference to the drawings of the specification of the present utility model.

Fig. 4 is a first structure of the utility model, which is provided with a conductive wire core 1 and an insulating sleeve 2 wrapping the wire core 1, wherein the cross section of the wire core 1 is in a regular hexagon shape, the wire core 1 is formed by bundling six wire cores 1-1 with the same shape and size and the cross section of which is in a regular triangle shape, the wire cores 1-1 are copper wires, the wire core 1 is formed by helically twisting the wire cores 1-1, the helical twisting is the same as the twisting pattern of the existing multi-strand wires, and the drawing is omitted.

It should be noted that the regular triangle of the split core 1-1 is not necessarily the complete triangle as illustrated, and should include a case having a proper transition rounded corner or transition flat top at a sharp angle of 60 degrees, because the split core 1-1 allows the transition rounded corner or transition flat top to be formed during drawing from a die, which can significantly reduce manufacturing cost, the regular hexagon and the regular triangle in the scheme should be understood as the outline shape of the cross section, and the split core 1-1 can be formed by rolling a cylindrical wire blank into a triangle by a roll arranged in a triangle.

Fig. 5 shows a second structure of the present utility model, in which a protective sheath 3 is further provided outside the wire insulation sheath 2, unlike the first structure.

The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of which is intended only to assist in understanding the methods of the present utility model and the core ideas thereof; also, it is within the scope of the present utility model to be modified by those of ordinary skill in the art in light of the present teachings. In view of the foregoing, this description should not be construed as limiting the utility model.
