Embodiment 1

[0102] Such as figure 1 with 2 Shown is the first specific implementation of the technical solution. The guide core of the cable 1 of this embodiment is composed of three guide core segments with different shapes (respectively the first guide core segment 11, the second guide core segment 12 and the second core guide segment 12). The third guide core segment 13) is connected end to end.

[0103] In this embodiment, the cross-section of the first core segment is W-shaped, the cross-section of the second core segment is wave-shaped, and the cross-section of the third core segment is arc-shaped. The upper surface of the rear end of the first core segment is in contact with the lower surface of the front end of the second core segment, and the rear end of the second core segment is in contact with the front end of the third core segment . Each guide core section is coated with an insulating layer made of PVC material.

[0104] In this embodiment, the cross-sectional shapes of ...

Embodiment 2

[0112] Such as image 3 Shown is the second specific implementation of the technical solution. The difference between this embodiment and Embodiment 1 is that the three sections of the cable 1 in this embodiment are polygonal core segments with different shapes, specifically: the cross section of the first core segment 11 is triangular in shape, and the second The cross-section of the guide core segment 12 is quadrilateral, and the cross-section of the third core guide segment 13 is pentagonal. The lower end of the rear end of the first core segment abuts against the upper end of the front end of the second core segment, and the lower end of the front end of the first core segment abuts against the upper end of the rear end of the third core segment. The other implementation conditions are the same as those in the first embodiment, and will not be repeated in this embodiment.

[0113] In this embodiment, the cross-sectional shape of the guide core segment is set in different...

Embodiment 4

[0118] Such as Figure 5 Shown is the fourth specific implementation of the technical solution. The guide core of the cable 1 in this embodiment is not connected by two or three guide core segments of the same shape or material, but by three guide core segments of different shapes or materials. Specifically, the first core segment 11 is a flexible elliptical stranded core segment, the second core segment 12 is a solid core segment with an octagonal cross-sectional area, and the third core segment 13 is a quadrilateral cross-sectional area. flexible stranded core section. The lower end of the rear end of the first core segment is connected to the upper end of the front end of the second core segment by welding, and the upper end of the rear end of the second core segment is connected to the lower end of the front end of the third core segment. connected by welding. As one of the preferred implementations, the welding method is ultrasonic welding. The upper and lower end sur...

Abstract

The invention discloses a special-shaped cable and a preparation method thereof. The conductive core of the special-shaped cable is composed of at least two conductive core segments in an end-to-end way, wherein the cross sections of the conductive core segments are different in shape. The conductive core segments are externally wrapped by an insulating layer. The contour of the insulating layer is fit with the conductive core segments. The cable has great bending performance and can also be greatly fit with a vehicle body so that consumables can be saved and the safety performance can be greatly enhanced. The cable is made of the aluminum or aluminum alloy conductive cores so that the vehicle body is enabled to be light-weighted, and the production cost of the motor vehicle can be reduced. The preparation method of the special-shaped cable comprises the steps of manufacturing the conductive core segments, connection of the conductive core segments and manufacturing of the insulating layer so that the production efficiency and the productivity can be effectively enhanced according to different production requirements and the production cost can be reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a special-shaped cable which is used in a motor vehicle and can be arranged according to the inner contour of the motor vehicle and a preparation method thereof. Background technique [0002] Existing cables for motor vehicles generally consist of a guide core and an insulating layer covering the guide core. At present, the cables used in motor vehicles are usually round, and some improved cables are flat. Due to the circular cross-section of the circular cable, the force on each point on the same circumference is isotropic, which makes it difficult to deform when subjected to external force, making it difficult to bend the wire harness cable. [0003] For this reason, Chinese invention patent CN 104112508 A discloses a new type of electric vehicle interior cable that adopts a flat design. Due to the flat structure, the bending radius in the direction perpendicular to the width of the solid core is t...
