Superior electrical connections 13 June 2024

A rapid increase in busbar manufacturing is pushing OEMs to look for new solutions to reduce electrical resistance and be more cost-effective. ECCB™ PEM eConnect™ Contact Bushing from PennEngineering® can be used to make reliable electrical connections between copper or aluminium busbars, PCBs or cable terminals.

Current solutions on the market have many limitations. These include unplated busbars that have the risk of corrosion, which increases resistance. Silver plating is then applied to busbars in a rack plating method that is slow, expensive and complex.

ECCB™ PEM eConnect™ Contact Bushing is answering these needs. It uses a high surface area knurl design to pierce the corrosion layer on busbars creating a consistent electrical current connection without needing to plate the busbar itself.

Designed for installation into straight punched holes without additional surface preparation, the ECCB™ PEM eConnect™ Contact Bushing also breaks aluminium and copper oxide layers on busbars for low resistance connections and are suitable for use in panels with sheet hardness HRB 50 / HB 82 or less.

For installation, PEM eConnect™ current carrying pins provide superior electrical connections in applications that demand superior performance from internal components. Available in self-clinching and broaching mounting styles, these installation systems are for use with electric vehicles including EV charging systems, EV powertrain, EV power distribution, as well as industrial switchgear.
