Connectivity for Engine and High Vibration Applications

Driven by the need for increased fuel efficiency and CO2 emissions reduction while improving performance, the next generation of internal combustion engines in passenger cars is characterized by their reduced size, increased power and engine speed (RPM). However, the higher vibration behavior of these new engine designs means that electrical connectors, that connect the electronics components within the engine bay, require new levels of vibration resistance not provided by standard connectors traditionally deployed in such applications.

Engine bay applications require sealed connectors capable of operating in temperatures up to 150°c and up to level 6 vibration severity

Engine bay applications require a high level of robustness ensuring reliability throughout the lifetime of the vehicle. That means a fully sealed design capable of operating in temperatures up to 150°c and up to level 6 vibration and be certified against the strictest automotive standards such as LV214.

 

Critically, connectors and contacts must be designed to avoid movement and surface layer destruction of the contact points.

 

This should include:

  • Minimization of connector movement at the connection interface
  • Avoidance of relative movement of the contacts
  • Reduction of cable movement

HPF Contact System for High Vibration Applications

TE Connectivity’s HPF contact system is designed to specifically to address the challenges to applications from the vibration profile of smaller sized next generation engines.


The HPF 1.2 contact system accommodates 1.2 mm x 0.6 mm tabs. It is designed to avoid micro movements caused by vibration at the points of contact. This is achieved by the contact zone being mechanically decoupled from the remaining terminal body and by the application of higher normal force to the point of contact.


A crimp-type connection is designed for connecting cables with cross-sections ranging between 0.35 mm2 and 1 mm2. A “meander” shaped geometry is designed to minimize micro movements introduced in the axial direction through the cable.
