The transformation in the automotive sector is progressing inexorably and thus the demands on the supplier industry are becoming increasingly complex, especially in electromechanics.

One of the greatest challenges is the significant growth of data streams within the vehicle. This will require new solutions and concepts in the near future, including with electromechanics and in particular from next generation connectors.

The second major challenge is the required power that a system of the future must be able to transmit. Continuous loads of up to 20 A and peaks >40 A are not uncommon and clearly show the growing user profile. The “hot-plug” and “always-on” requirements have also been part of OEMs’ specifications for some time.

Yamaichi Electronics, in close cooperation with a large German OEM, has already developed an interface for this, which maps the above-mentioned user profiles. The interface is called Y-CCC, which stands for Yamaichi-Car-Computer-Connector.

With this hybrid connector, it is possible to accommodate the requirements for power, signals and high-speed data in one receptacle size and to transmit them accordingly. In order to meet the high demands of the automotive industry (vibration and shock for example), the materials and the design were laid out and internally tested according to the common automotive standards such as LV214 and VDA.

The zinc die-cast connector housing offers an optimal compromise in terms of electrical shielding properties (signal integrity) and the required vibration resistance.

The current configuration of the Y-CCC connector system is as follows:

  • 56 signal contacts.
  • 48 differential pairs for high-speed transmission up to PCIe 4.0.
  • 8 power contacts up to 20 A.
  • TH reflow solder version.
  • Screw mounting of the backplane connector.

Yamaichi Electronics is aware that this is probably not the last iteration stage, and can offer all interested parties the currently available connector system, which can also then be adapted to cater for other requirements or profiles.
