At the Heart of the Vehicle: Customized Interface Connectors from ept

It is not uncommon for the engine controller to be referred to as the heart of any motorized vehicle. Once an analog computer, now it handles not only fuel injection and ignition, but also the control of turbochargers, the monitoring of exhaust gas values, the operation of start/stop systems and countless other functions. This increasing complexity poses new challenges for connection technologies.

Requirements of the new Connectors

Like the human heart, the engine controller must also ensure reliable operation. To do so, both it and its components must withstand extreme conditions such as vibrations, high voltages and a tremendously wide range of temperatures. Therefore, it is necessary that the built-in PCB connectors are always sturdy and reliable accordingly, while maintaining cost-effectiveness. Since the risk of metal whiskering is increased under such extreme conditions, it became necessary to seek an alternative to the usual tin for the pin material.

Individual Interface Connectors upon Request

Einpresstechnik Tcom Frei
Press-fit zone Tcom press®
As a one-stop supplier, ept developed a customized interface connector for the sensors and actuators in the engine controller for a major German automotive supplier. To meet customer requirements, a combination of stitch technology and press-fit process was chosen for production. On the one hand, the proven Tcom press® press-fit zone made it possible to produce a gas-tight, durable, electrically conductive, and mechanical connection with low contact resistance. On the other hand, the stitch technology enabled a cost-effective solution in which the gold coating of individual pins ensures the fastest possible signal transmission to the respective sensors and actuators. In this way, it was possible to ensure that the re-design of a 154-pole connector had the required robustness while at the same time being economical. ept countered the problem of whiskering by using a special silver-tin alloy for the pins.
ept was able to convince the customer through...
  • its many years of expertise in the press-fit process with the proven press-fit zone Tcom press®
  • the use of the cost-effective stitch technology, which enables the selective gold plating of individual pins
  • the use of a silver-tin alloy as pin material for minimized whiskering
