Problems solved by technology

[0003] The purpose of the present invention is to provide a flat flexible cable with good electrical conductivity. By covering the outer sides of the three shielding layers with an aluminum-plastic composite layer and making the two adjacent shielding layers close to each other, it is more efficient to produce. It is convenient, and at the same time, it changes the traditional situation that each wire group is set independently and is not easy to bend. The cable has good flexibility, which can significantly shorten the production cycle, and solves the technical problems of long production cycle and poor flexibility of traditional cables;

Embodiment 1

[0036] Such as Figure 1-5 As shown, a flat flexible cable with good electrical conductivity includes a nitrile polyvinyl chloride sheath layer 2, and an aluminum-plastic composite layer 5 is arranged on the inside of the nitrile polyvinyl chloride sheath layer 2, and the aluminum-plastic composite layer 5 Three shielding layers 4 are arranged inside, and seven conductors are arranged inside each of the three shielding layers 4 , and the conductors include the wire 1 and the insulating layer 3 wrapped outside the wire 1 .

[0037] Two adjacent shielding layers 4 are in close contact.

[0038] The production method of this shielding layer 4 specifically comprises the following steps:

[0039] Step 1. Place the two ends of the aluminum foil on the inside of the two channel steel pallets 15 in the shielding layer processing device, and make the ends of the aluminum foil under the corresponding splint 16, start two third cylinders 17, and the third cylinder 17 The output rod of ...

Embodiment 2

[0048] Such as Figure 1-5 As shown, the production method of the shielding layer 4 specifically includes the following steps:

[0049] Step 1, with embodiment 1;

[0050] Step 2. When the aluminum foil is covered with dents, the mobile trolley 30 drives the mobile support 26 to move, the mobile support 26 drives the lifting horizontal plate 27 to move, and the lifting horizontal plate 27 drives the installation frame plate 14 to move to the tin liquid through the fixed arm 29 Above the tank 23, make the aluminum foil above the tin liquid tank 23, start the second motor 21, the output shaft of the second motor 21 rotates and drives the screw 22 to rotate, the screw 22 drives the lifting seat 19 to descend, and the lifting seat 19 passes through the connecting horizontal plate 20 drives the lifting horizontal plate 27 to descend, and drives the installation frame plate 14 to descend, and drives the aluminum foil to descend, so that the aluminum foil is immersed in the tin liqu...

Abstract

A flat flexible cable with good conductivity disclosed by the present invention comprises a butyronitrile polyvinyl chloride sheath layer, an aluminum-plastic composite layer is arranged on the innerside of the butyronitrile polyvinyl chloride sheath layer, three shielding layers are arranged on the inner side of the aluminum-plastic composite layer, and seven conductors are arranged on the innersides of the three shielding layers; and each conductor comprises a wire and an insulating layer wrapping the wire. The cable is more convenient to produce, and changes the situation that conventional wire sets are independently arranged and inconvenient to bend; the cable is good in flexibility, the production period can be obviously shortened, the aluminum foil is comprehensively extruded through the pressing plate, the aluminum foil is full of dents before tin immersion, the tin liquid adsorption capacity is improved, and the production efficiency is improved. Meanwhile, the tin content ofthe surface of the aluminum foil in unit area is improved, the conductivity of the shielding layer is improved, the power transmission performance of the cable can be effectively improved, the current-carrying capacity of the cable is improved, the thermal stability of the shielding layer is improved, the shielding layer has good conductivity, the use amount of wires can be reduced, and the costis reduced.

Description

technical field [0001] The invention relates to a cable, in particular to a flat flexible cable with good electrical conductivity. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Insulating covering. The cable has the characteristics of internal energization and external insulation. Each wire group of the traditional cable is set independently, so it is not easy to bend and has poor flexibility. This kind of cable has a long cycle to produce. The shielding layer of the traditional cable has a single function and cannot conduct electricity. The wire is used for conducting electricity, and the wire is generally made of copper, and the cost is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a flat flexible cable with good electrical conduc...
