Embodiment 1

[0022] Such as figure 1 As shown, it is the flexible busbar of this embodiment, with a cross-sectional area of ​​70mm 2 . The soft busbar of this embodiment includes a conductor body, and the conductive body is covered with an insulating layer 3 (the insulating layer on the right half of the soft busbar is not on the figure 1 shown in ), the insulating layer is formed by dipping process. The above-mentioned conductive body is a wire bundle with an upper and lower two-layer structure, each layer structure of the wire bundle includes 12 wires 6 and the wires of each layer are arranged side by side. Each conductor is twisted by 22 T2 sub-conductor copper wires with a diameter of 0.42mm. The wire harness is provided with a bending area 1 and fixing areas 2 located on both sides of the bending area in the extending direction of the conductive body. The parts of the wires in the bending area are not fixed to each other, that is, they can move relative to each other. The part of...

Embodiment 2

[0026] The only difference between this embodiment and Embodiment 1 is that the flexible busbar of this embodiment is only provided with one kind of bending such as image 3 As shown in middle bend 12, the bend shown in bend 12 is a twisted bend. After bending, the planes on both sides of the bend are perpendicular to each other and the extension lines of the two sides are perpendicular to each other. In this embodiment, the connecting end of the soft busbar is provided with a waist-shaped bolt hole 13 that passes through the metal connection belt and the wire harness.

Abstract

The invention relates to a flexible bus and a preparation method thereof, and belongs to the technical field of power supply and distribution equipment. The flexible bus comprises a conductive body which is a lead bundle formed by multiple leads. The lead bundle comprises a bending area and fixing areas which are arranged on the two sides of the bending area in the extension direction of the conductive body. The parts corresponding to the fixing areas of all the leads are mutually fixed. The insulating flexible bus is simple and reliable and can save installing space and has excellent bendingand safety performance.

Description

technical field [0001] The invention relates to a soft busbar and a preparation method thereof, belonging to the technical field of power supply and distribution equipment. Background technique [0002] The power supply is an important part of the electric vehicle, and the power battery is an important part of the power supply system. The connection of the power battery and the connections of the electrical components in the power system are mainly realized through the soft busbar conductor, which is mainly used to export the battery current. , forming a complete circuit by passing between systems. The currently used soft busbars are mainly made of T2 copper strips with a thickness of 0.1mm or 0.5mm and a width of no more than 30mm, which are made by blanking, stacking, welding, punching, shape processing and insulation treatment. The soft connection with this structure has the characteristics of simple process, good reliability, low impedance, simple and fast assembly, etc...
