BIZON high-current press-in

High performance press-in connection elements are required in order to satisfy increasingly stringent demands in automotive applications. Press-in connections are also have proven installation benefits and significantly higher reliability compared to screw and soldered connections when used in critical applications in the automotive sector. The proportion of high-performance electronics used in motor vehicles is increasing which means a whole range of new requirements to be met by press-in connections now exist. Low-priced standard PCBs can be manufactured despite the high currents being handled.

BINDER tecsys GmbH applies the BIZON concept when implementing these press-in zones which satisfies the most rigorous inspections and stringent demands to DIN EN 60352-5.

High current carrying capacity with minimum space requirement is one of the most important characteristics of the BIZON contact. The more or less square cross-section in the plated-through hole and the special form and manufacturing method of the contact provide many technical benefits and an attractive price-performance ratio.
