[0005] Furthermore, there are a plurality of three-core electric wires, and the three-core electric wires are located in the same layer or in different layers, and an intermediate insulating layer is provided between the three-core electric wires in each layer.

[0006] Furthermore, the conductive plate is made of aluminum, and the thickness of the conductive plate is 1 mm to 3 mm.

[0007] Furthermore, the upper insulating layer, the conductive plate insulating layer and the lower insulating layer are made of PET or PI materials, and the thickness of the upper insulating layer, the conductive plate insulating layer and the lower insulating layer is 0.05 mm to 0.4 mm.

[0008] The present invention also discloses a method for manufacturing a conductive bar with three core wires, the steps of which are:

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the conductive bar structure with three core wires.

[0013] Markings in the figure are: three-core wire 1, conductive plate insulating layer 2, conductive plate 3, lower insulating layer 4, glue 5. DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1 The conductive row with three core wires shown in the figure comprises at least one three-core wire 1 including an insulating sleeve and a shielding sleeve, a conductive plate insulating layer 2, a conductive plate 3 and a lower insulating layer 4 arranged in sequence from top to bottom. The three-core wire 1, the conductive plate insulating layer 2, the conductive plate 3 and the lower insulating layer 4 are laminated and fixed in sequence by glue 5. The gap between the three-core wire 1 and the conductive plate insulating layer 2 is filled with glue 5. This structure allows the three-core wire 1 and the conductive plate 3 to be pressed together, so that the entire wire row structure has a certain rigidity. Before installation, The production bending can be pre-performed at a certain bending angle and bending radius according to the connection requirements of the electrical equipment in the spatial position of the vehicle, and then a robot can be used to pick up, position, install and inspect the whole vehicle factory, which is of great help to the automated production of electrical connections in the whole vehicle factory. In addition, since the gap between the three-core electric wire 1 and the insulating layer 2 of the conductive plate is filled with glue 5, and since the cross-section of the three-core electric wire 1 is circular, the contact area between the three-core electric wire 1 and the insulating layer 2 of the conductive plate is small. The filling with glue 5 can make the three-core electric wire 1 and the insulating layer 2 of the conductive plate more firmly bonded, so that the conductive row will not be displaced during the bending process, thereby ensuring the quality of the conductive row structure. At the same time, because the three-core electric wire 1 itself has an insulating sleeve and a shielding sleeve, the use of the insulating sleeve and the shielding sleeve can be reduced when producing the conductive row, thereby facilitating the production of the conductive row.

[0016] On the basis of the above, if Figure 1As shown, there are multiple three-core wires 1, and the multiple three-core wires 1 are located in the same layer or different layers. An intermediate insulating layer is provided between each layer of three-core wires 1. Similar to the above, the three-core wires 1 and the intermediate insulating layer are also laminated and fixed using glue 5. During design, the three-core wires 1 can be laminated at different positions and different numbers of layers in the conductive row structure according to the specific electrical connection structure, so that the connection circuits are highly integrated.

[0017] On the basis of the above, the conductive plate 3 can be any conductive material such as aluminum and copper. Aluminum is used here. The thickness of the conductive plate 3 is 1mm to 3mm. The lower insulating layer 4 and the conductive plate insulating layer 2 are PET or PI materials. The molecular structure of the PET plastic is highly symmetrical and has a certain crystal orientation ability, so it has a high film-forming property. The PET plastic has good optical properties and weather resistance. The amorphous PET plastic has good optical transparency. In addition, PET plastic has excellent wear resistance, dimensional stability and electrical insulation. The PI is the abbreviation of polyimide. The main performance characteristics of PI are high temperature resistance, wear resistance, insulation, etc. The thickness of each insulating layer is 0.05mm to 0.4mm. The above materials and the thickness of each material are limited, so that the conductive row structure is moderately rigid, can be bent, and will not rebound after bending, and will not break during the bending process.

[0018] The present invention also discloses a method for manufacturing a conductive bar with three core wires, the steps of which are:

[0019] A. The three-core electric wire 1 including the insulating sleeve and the shielding sleeve, the conductive plate insulating layer 2, the conductive plate 3 and the lower insulating layer 4 are laminated and fixed in sequence by adhesive.

[0020] B. Bend the conductive bar with three core wires in step A into the required installation structure.
