The new energy vehicle connector should not be reduced to "supporting role" like the traditional automobile field, but should give full play to its importance. Here we will analyze how to design connectors to occupy the new energy vehicle market.
With the continuous development of electronic technology in recent years, the application of connectors in microelectronics, automobile industry and medical industry has become more and more attractive. The components are getting smaller and smaller, the circuit density is getting higher and higher, and the transmission speed is getting faster and faster. Connectors are developing in the direction of high density, miniaturization, thinness, combination, high-speed, small batch and multiple varieties, which will become a new growth point in the connector industry.
Environmentally friendly energy vehicles, green components Because new energy vehicles are "green" vehicles, connectors are also required to be green. Whether in the production or practical application of components, using green materials, avoiding pollution and reducing energy consumption have become factors that manufacturers must consider, and these green characteristics will also become market advantages of products.
Safety
Since the connectors of new energy vehicles can withstand up to 250A current and 600V voltage, the demand for high standards of electric shock protection is obvious. At the same time, at such high power, electromagnetic interference is another important problem. In addition, the plug and pull operation of the connector will produce electric arc, which will seriously endanger the electrical connection and electronic equipment, and may lead to vehicle combustion. These all require special design and development of connectors, such as preventing high-voltage breakdown when exposed to air, which requires a certain air gap; Under the condition of high voltage and high current, the temperature rise shall not exceed the rated value; When selecting the shell material, it is necessary to consider the weight, strength and workability, as well as how to maintain the stability of the connector terminal material performance at different temperatures, and how to ensure the necessary conductivity.
Connectivity
With the continuous expansion of automobile entertainment system, the importance of high-speed data transmission is increasingly prominent. "For example, in some models, a camera is installed on the reversing mirror, which enables the driver to have a broader view, which requires the connector to transmit more data. Sometimes a connector is required to transmit GPS signals and radio signals at the same time, so its data transmission capability needs to be improved."
Otherwise, because the car engine is usually placed in front of the car, and although it is protected by a firewall, it will conduct some heat, so the connector should be able to withstand high temperature. In addition, the "harsh" requirements for automobile connectors are also reflected in the service life. Generally, there are elastic elements in the connector, which will fail after plugging and unplugging for a certain number of times, so the service life is generally about 3-5 years, while a vehicle can last 10-20 years. Therefore, the service life of automobile connectors must be comparable to that of automobiles, and the requirements for connectors are quite high.
New markets and new opportunities, but there are also many challenges and difficulties. After the capital accumulation brought by rough processing and assembly mode, China's industry should put more resources and energy on product upgrading and research and development. Make it no longer subject to others in the future market. New energy vehicles not only bring broad market space for electronic components including connectors, but also provide a good opportunity for product upgrading.
