Description

Technical Field

[0001] The invention relates to the technical field of electric wires and cables, in particular to a multi-core splittable cable. Background Art

[0002] The current high price of copper materials has put great pressure on cable manufacturers and cable users. Existing cable users have some waste in the use of cables. For example, the actual working conditions require the use of 7mm 2 The copper core wire has no cross-sectional area of 7mm 2 For copper core wire, you can only choose 10mm 2 The copper core conductor causes a waste of materials. In addition, cable manufacturing companies generally produce according to orders. If too many cross-sectional specifications are produced within a period of time, the company's production and supply work will be extremely cumbersome, the work efficiency will be low, and there will be a waste of manpower and material resources. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-core splittable cable, which overcomes the problems of waste in use and low manufacturing efficiency of existing cables.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a multi-core splittable cable, comprising a plurality of conductors arranged in parallel at intervals and in the same arrangement plane when initially straightened and flattened before use, each conductor being wrapped with an insulating sleeve, the direction perpendicular to the arrangement plane being the height direction of the cable, the axial direction of the conductor being the length direction of the cable, and the arrangement direction of the conductor being the width direction of the cable, each two adjacent insulating sleeves being connected by a connecting and cutting portion integrally provided with the two insulating sleeves, and the minimum height of the connecting and cutting portion being less than or equal to the minimum height of the insulating sleeve.

[0005] Specifically, a structure that helps to keep cables close together during wiring, the outer contour of the cross section of the insulating sleeve is a hexagon.

[0006] Furthermore, the cross-section of the hexagonal outline of the insulating sleeve has a top side and a bottom side that are both parallel to the arrangement plane. The hexagonal shape is composed of a middle rectangle and an isosceles triangle with right angles at the top angles on both sides of the rectangle. The bases of the two isosceles triangles are the two opposite sides of the rectangle, and the connecting and cutting portion connects two adjacent insulating sleeves at the top angles of the isosceles triangles.

[0007] Specifically, in order to facilitate cutting, the connecting and cutting portion is provided with a cutting line in the same direction as the length direction of the cable, and the cutting line has intermittent incisions, and the connecting and cutting portion at the incision is cut off in the width direction of the cable.

[0008] Specifically, the cross-sectional shape of the connecting and cutting portion is a rectangle, or the cross-sectional shape of the connecting and cutting portion is a waist drum shape with a thinner middle portion and wider ends.

[0009] The beneficial effects of the present invention are as follows: the multi-core splittable cable of the present invention is equivalent to connecting several conductor core insulation sleeve units in the lateral direction with a split connection part, and the thin split connection part and the insulation sleeve are an integrated structure. When the cable is used, it can be cut at the split connection part according to the required conductor cross-sectional area to form a non-standard specification cable, thereby reducing the waste of conductor core material. Compared with the slightly increased amount of insulation sleeve material, the excellent effect of saving conductor material and efficient production of the manufacturing enterprise is more prominent; the cross-sectional shape of the insulation sleeve can be designed to be a shape that is convenient for being put together during wiring, such as a hexagon, and the putting together includes curling and putting together or folding and putting together like a folding fan.

[0012] The technical solutions in the embodiments of the present invention are described in detail below in conjunction with the accompanying drawings of the present invention specification.

[0013] As attached Figure 1 and 2A multi-core separable cable, having seven conductors 1 arranged in parallel at intervals and in the same arrangement plane in the initial straightening and flattening state before use. The number of conductors 1 can be less than seven or more than seven. Each conductor 1 is wrapped with an insulating sleeve 2. The direction perpendicular to the arrangement plane is the height direction of the cable, the axial direction of the conductor 1 is the length direction of the cable, and the arrangement direction of the conductors 1 is the width direction of the cable. Each adjacent pair of insulating sleeves 2 is connected by a connecting and cutting part 3 integrally provided with the two insulating sleeves 2. The minimum height of the connecting and cutting part 3 is less than or equal to the minimum height of the insulating sleeve 2, and the average height of the connecting and cutting part 3 is less than the average height of the insulating sleeve 2. The average height of the connecting and cutting part 3 is the average value of the maximum height and the minimum height of the connecting and cutting part 3, and the average height of the insulating sleeve 2 is the average value of the maximum height and the minimum height of the insulating sleeve 2. The cross-sectional outer contour shape of the insulating sleeve 2 is a hexagon, and the cross-sectional outer contour shape of the insulating sleeve 2 can also be a circle, an ellipse, a parallelogram with equal side lengths, etc. The cross-section of the insulating sleeve 2 with a hexagonal contour has a top side 2-1 and a bottom side 2-2 parallel to the arrangement plane. The hexagon is composed of a middle rectangle and two isosceles triangles with right-angled vertices on both sides of the rectangle. The bases of the two isosceles triangles are the two opposite sides of the rectangle, and the connecting and cutting part 3 connects two adjacent insulating sleeves 2 at the top angles of the isosceles triangles.

[0014] Still see Figure 1 , A dividing line in the same direction as the cable length direction is provided on the connecting and cutting part 3, and intermittent cuts 3-1 are provided on the dividing line. The connecting and cutting part 3 at the cuts 3-1 is cut off in the cable width direction..

[0015] A structure such as Figure 3 , The cross-sectional shape of the connecting and cutting part 3 is a rectangle, and the height of the connecting and cutting part 3 is equal to the minimum height of the insulating sleeve 2. The height at the junction of the insulating sleeve 2 and the connecting and cutting part 3 is the minimum height of the insulating sleeve 2 and also the height of the connecting and cutting part 3.

[0016] Another structure such as Figure 4 , The cross-sectional shape of the connecting and cutting part 3 is a waist drum shape that is thinner in the middle and wider at both ends, and the minimum height of the connecting and cutting part 3 is less than the minimum height of the insulating sleeve 2.

[0017] When the cross-sectional outer contour shape of the insulating sleeve 2 is a hexagon, the cable can be bent and joined together during wiring as Figure 5 shown, Figure 5 To fully show the joined-together situation, the shape of a seven-conductor cable is also drawn, which has nothing to do with the seven conductors of Figure 1 , that is, it does not mean Figure 1 the cable of Figure 5 cannot be cut,

[0018] When the cable of the present invention is produced, it is wound around a cable reel in pieces.

[0019] In this article, specific examples are used to illustrate the principle and implementation mode of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation on the present invention.
