Flexible Bus Bar

Flexible bus bar, also called as bus bar expansion joint, bus bar expansion connector, copper foil flexible bus bar, copper strip flexible bus bar. It is a kind of flexible connecting part that is used to compensate for bus bar deformation and vibration deformation caused by temperature changes. It is applied in battery pack or the electric connecting between laminated bus bars.

The flexible bus bar( bus bar expansion joint) can be divided into the following categories: copper strip or foil flexible bus bar, copper bus flexible connection, copper stranded wire flexible connection, copper wire braid flexible connection,etc.

The flexible bus bar is a customized electric connector based on user’s drawing and technical requirements.

Process Technology For Flexible Bus Bar

The manufacturing process of flexible bus bar is press welding or braze welding

1) press welding

As per the drawings and technical requirement, put multi-layer of copper strips, copper foils or aluminum strip stacked together, then use the molecular diffusion press welding to laminate by high current heating.

Thickness of copper foil (or strip) normally used: 0.05mm~0.3mm.

The electric contact surface can be tin plated, nickel plated or silver plated according to user’s requirement.
