Automated bending for cross connectors

For contacting the junction box are generally the cross-connectors bent into L-angles. Therefor there are two alternatives. "Self-bending" or buy "ready-made connectors". When purchasing the material supplier cuts and bends the cross connector on a fully automatic machine. So he is able to achieve a good quality. However, the disadvantage is higher cost and what is more important the higher cost of logistics, this is reflected in longer delivery times, higher costs for packaging, shipping and storage, and losses due to bending of the already prebent bulky L-connector.

Do you have any questions ?
We would like to inform you!


For a good cell contacting, the cell connectors / Ribbons have to be stretched. The mechanical elongation decreases the thermal elongation during soldering because of heating and cooling. So mechanical stresses between the cell and cell connectors are reduced also.
