Based on its vast expertise in the field of connectors and board design, ERNI Electronics is expanding its services and offering of key components for the central electronics in commercial vehicles. In this regard, the company is addressing the areas of the driver’s cab, the exterior and the engine compartment of buses, construction machines, trucks, tractors and tractor units. To ensure reliable connections also in the case of higher currents, for these applications, ERNI draws on its wide-ranging expertise in press-fit technology, in the assembly of PCBs and as an EMS service provider. Its experienced and highly qualified electronics developers have a long and proven track record of accompanying projects in these fields.
“The range of services offered under the BLUEcontact Solutions label encompasses the complete project management from the first prototype through to series production, the routing of the PCBs, development and delivery of the mechanical components, plus the integration of the board component“, stated Mario Tolj, Project Manager BLUEcontact Solutions. „Our service offering is completed by a complementary product portfolio including a wide array of fuse sockets, relay sockets as well as PCB and cable connectors leveraging from the benefits of the flexible press-fit zone,“ added Thomas Engel, Project Manager BLUEcontact Solutions.

Working closely with the customers, the key criteria are discussed in advance with regard to providing optimised BLUEcontact Solutions, e.g.: How much space is available for the central electronics? Is the installation position restricted? Is a housing necessary? Can the central electronics be implemented in the passenger compartment or does it have to go into a harsher environment? Is there a risk of condensation? How high is the stress due to vibration loads? Etc.

Within the scope of its BLUEcontact Solutions, ERNI also offers a wide range of power elements with a combined flexible and solid press-fit zone. Whilst the solid press-fit zone is used for absorbing the torque and providing a secure fastening, the flexible press-fit zone ensures efficient power transmission.

In addition, the offering also includes a variety of fuse sockets, relay sockets as well as PCB and cable connectors for commercial vehicles with a flexible press-fit zone. For these in-house developments, the company draws on its wide-ranging internal tooling and manufacturing resources.

These robust components for commercial vehicles are based on a modular design, offering high number of contact points and press-fit contacts. The smooth press-fit technology prevents damage to the PCBs. Furthermore, this also produces a shock and vibration-proof connection coupled with high current carrying capacity. Compared with the pure solid press-fit technology commonly used to date in this area, the components from ERNI offer numerous processing advantages:
• No cracking of the conducting paths to the nozzle effect during press-fitting
• Minimal chipping during press-fitting
• Low risk of delamination and associated short circuits due to moisture being trapped in the PCB
• Greater reliability when exposed to temperature changes and vibrations
• Enhanced process reliability of the press-in and press-out forces
• Greater hole tolerances coupled with lower costs for the PCB
• Better reparability
• Better adaptation of the press-in force to the application
• Lower press-in forces coupled with high pole number, less stress for the PCB
• Enhanced power transmission
• General stress reduction of the PCB
