Cable-to-board connector targets the automotive industry

April 21, 2020 // By Julien Happich
Delivered in a 1.27mm pitch ERNI’s single-row MicroBridge cable-to-board connector has been developed in accordance with the demanding automotive test specifications VW75174 and USCAR-2.

Koshiri security, an optional electrical connector position assurance (e-CPA) and possible color and mechanical coding for any number of pins ensure safe and reliable connections. Koshiri security means protection against damage caused by improper or skewed insertion. With the MicroBridge, tongues on the female connector and grooves on the male connector allow the pre-alignment of the connector housings, ensuring a precise mating process. The contact pins of the male connector are not damaged by improper, skewed mating. The e-CPA enables testing for secure contact between the female and male connectors even during the mating process. A shortened test pin (without signal and power supply function) is used on the male connector for this purpose. This connector can withstand the harsh environmental conditions with vibrations or shock loads and high temperatures in the vehicle. The housing latching mechanism on both sides provides acoustic and haptic feedback of the interlocking during the mating process. The latching mechanism can be released without tools. The solder clips of the male connectors absorb mechanical stress and resist high shock and vibration loads. The high-temperature resistance of up to 150 °C allows the connectors to be used in areas exposed to demanding temperature conditions, e.g. close to LEDs in the headlights. Current rating per contact is specified at 9.0 A at 20 °C (2-pin version).
