Embodiment 1

[0027] S1. Material selection: T2 red copper is selected before production. T2 red copper is 0.1mm thick red copper foil. Put the selected red copper foil into the heating furnace and heat it to 900°C. After the temperature reaches the standard, transfer the material from the heating furnace In the thermoforming press, the red copper foil is stamped and formed according to the mold in the press to obtain a red copper sheet, and the red copper sheet is rapidly cooled by water cooling at a temperature of 10°C to harden the red copper sheet. increase strength;

[0028] S2. Surface treatment: Use punching equipment to punch holes on both sides of the surface of the copper sheet to form two connection holes 6, namely the first connection part 2 and the second connection part 3. After the punching is completed, the copper plate Remove burrs and blunt sharp corners on the surface of the material, so that there are no sharp edges on the surface and no damage to the outer surface;

Abstract

The invention discloses a deformable soft copper bar. The copper bar comprises a copper bar main body, a first connecting part and a second connecting part, wherein two side ends of the copper bar main body are respectively provided with a first bending part and a second bending part, the side edge of the first connecting part is fixedly connected with the outer side edge of the first bending part, and the top of the second connecting part is fixedly connected with the outer side edge of the second bending part. The invention relates to the technical field of battery module fixing. The deformable soft copper bar can generate deformation within a certain range, the strength requirement can be met, the internal space of the power battery pack can be saved, each electric device in the batterypack can be connected more stably, the advantages of small resistance and strong over-current capability are ensured, the advantage of flexibility is brought, the soft copper bar can eliminate the stress generated during installation and reduce the installation difficulty, and the soft copper bar can be widely applied to new energy automobile power batteries and can be applied to rail transit andpower and electrician industries.

Description

technical field [0001] The invention relates to the technical field of fixing battery modules, in particular to a deformable soft copper bar. Background technique [0002] With the development of the new energy vehicle industry, the power batteries used in new energy vehicles are gradually replacing traditional energy consumption methods and entering our lives. The power battery system is huge and complex. It is composed of a single battery cell connected in series and parallel to form a module, and then a complete set of battery system is composed of a well-assembled module. [0003] The internal structure of the power battery pack saves the internal space to a great extent, and also makes the battery cells in the whole system more regular. However, as time goes by, the degree of use increases. The connection of the group is unstable, which can easily cause rigid contact between adjacent modules, between the module and the power battery pack shell, and may also cause bumps...
