Leading manufacturers are also investing in connector capabilities that rise to the global miniaturization challenge, while at the same time ensuring superior performance and compatibility. Typical miniaturized connector attributes and options provided by modern manufacturers include:
Standards Compliance
• High-current density and robustness that conforms to the AK organization of German car manufacturers’ specifications and standards
• A connector that meets USCAR-2 specifications for automotive electrical connector systems and is tested to LV214 and PSA
• A system that includes a German auto standard 050 interface with locking-lance terminal and side-latch design
Space Savings
• Unsealed hybrid headers and receptacles that deliver both signal and Ethernet connectivity within a small footprint
• Significant space and weight savings compared to 0.63mm systems
• A 1.80mm pitch that reduces the spatial envelope by up to 50%
• The ability to utilize wire gauge as small as 0.13mm
Design Flexibility
• Two-piece constructions that offer greater durability and reliability
• The option for multiple configurations and circuit sizes
• A choice between sealed or unsealed single- and dual-row receptacles
• Clean-body terminal options
• Stackable header and connector systems that offer 0.5mm, 1.2mm, and 2.8mm options
Looking Ahead: Future Trends
Driven in large part by accelerating investment in autonomous and smart vehicles, and by extension advanced driver-assist technologies, the continued evolution of in-vehicle Ethernet systems will increase the demand for 0.5mm terminals. According to McKinsey, “Today’s vehicle networks are insufficient for the requirements of future vehicles. Increased data rates and redundancy requirements for HAD [highly automated driving], safety[,] and security in connected environments, and the need for interindustry standardized protocols will most likely result in the emergence of the automotive Ethernet as a key enabler, especially for the redundant central data bus. Ethernet solutions will be required to ensure reliable interdomain communication and satisfy real-time requirements by adding Ethernet extensions like audio-video bridging (AVB) and time-sensitive networks (TSN).” This evolution includes the creation of data and signal hybrids, which entails combining signals with high-speed mini FAKRA (HFM) and Ethernet to reduce connections and save space. In addition, it will include an increase in the development of in-line and wire- to-board options.
Miniaturization is the future of automotive connectors. Modern vehicles will continue to require greater bandwidth, enhanced safety features and, for driverless cars and trucks, sophisticated anti-hacking systems. This will drive growth in the number of connectors used, amplifying the demand for them to fit into increasingly smaller spaces.
