Automotive Connector Strategies and Solutions for Space Saving Page 8 TE AUTOMOTIVE /// White Paper | Automotive Connector Strategies and Solutions for Space Savings 9 | HOW THE NanoMQS PLATFORM SUPPORTS UP TO LEVEL FOUR HIGH VIBRATION RESISTANCE Electric connections within vehicles must sustain vibration and shock resistance. Miniaturized components such as the NanoMQS intercon- nection system are often deployed in sub-system modules, known as "black boxes," in severely space-constrained spaces that are hard to access. In Europe, major German vehicle manufacturers define vibration test levels in specifications such as LV 214. The standard unsealed versions of the NanoMQS series meet the LV214 level 4 (Ag-plated contacts) at around 181 m/s2 effective acceleration. This is notable because the NanoMQS system meets the require- ment for a sealed connector. With the high-contact normal force of the NanoMQS system, connectors incorporating an additional seal can achieve level three vibration for close-proximity installation and level four vibration in the case of direct engine mounting (Figure 8).. Robust by design, NanoMQS terminals and connectors can also meet very high 400 g sinus vibration resistance requirements, as stipulated for injection valves or other direct engine mounted applications. 10 | INTRODUCING MCON 0.50 INTERCONNECTION SYSTEM FOR EXTREMELY HARSH AUTOMOTIVE ENVIRONMENTS The MCON 0.50 interconnection sys- tem is part of TE's MCON intercon- nection product family, which has been designed for deployment in very harsh automotive environments. It is a sealed system that features specially engineered silicone seals. These seals prevent fluid and mois- ture ingress into areas of electrical contact, which is required for appli- cations found in the engine bay area. MCON 0.50 terminals and connectors meet LV214 level 3 requirements for close-proximity installations and level 4 requirements for direct engine mounting. It also achieves an IP9 level of water protection. Unlike NanoMQS interconnection system and the rest of the MCON family, the MCON 0.50 terminal by design has no primary locking lance, offering what is known as a "clean-body approach" (Figure 9). This means that there are no flanges that extend out from the connector to lock it into place inside the hous- ing, creating a cleaner body profile. This design is intended to minimize any wear and tear on the interior of the connector housing, which might compromise the moisture seal. The sealed version provides the very highest level of water and moisture resistance. MCON 0.50 systems can be submerged in several meters of water and take 80 bars of force from an IPX steam jet.
