In the realm of automotive applications, the demand for reliable and durable connectors is paramount, especially as these connectors are tasked with delivering more functionalities in increasingly smaller and lighter spaces. Let's delve into the trends of wiring harnesses for new energy electric vehicles.
Given that new energy vehicles epitomize environmental friendliness, connectors are also expected to adhere to green standards. Foremost among these requirements is safety, as the operating voltage ranges from 400V to 600V, with currents ranging from 50A to 300A, or even higher. Considering that operators inevitably come into contact with the engine compartment throughout the vehicle's lifecycle, the need for stringent anti-electric shock protection is evident. Additionally, at such high power levels, electromagnetic interference becomes a significant concern. Furthermore, the arcing that occurs during connector insertion and removal poses a serious threat to electrical connections and electronic devices, potentially leading to vehicle fires. Addressing these issues necessitates specialized design and development of connectors.
Meeting the high-performance requirements of wiring harnesses for new energy electric vehicles primarily relies on stringent design specifications. For instance, preventing air breakdown under high voltage in exposed conditions requires maintaining certain air gaps. The temperature rise under high voltage and large currents must not exceed rated values. When selecting housing materials, considerations include weight, strength, and ease of processing. Furthermore, the stability of terminal materials' performance under different temperatures and ensuring necessary conductivity levels must also be taken into account.
The technological trends in wiring harnesses for new energy vehicles lean towards connector product "miniaturization," "high-speed mobility," and intelligence. Future industry innovations primarily focus on the development of connector miniaturization technology, which can be applied to connectors below the millimeter scale, belonging to the MINIUSB series of new products. These connectors can be used for multi-contact expansion slot connectors, surpassing the stringent requirements for contact co-planarity set by multi-contact surface adhesive technology, with high efficiency and low cost. High-speed transmission connector technology caters to various device communication applications, boasting a wide range of applications.
