Low-voltage connectors/Low-speed connectors

Connectors are mainly used in critical areas such as ECUs (Electronic Control Units), sensors, etc. Their low voltage characteristics are characterized by currents in the range of a few amperes (A) and voltages up to 60 volts (V). These connectors consist of plastic parts, terminals (including signal and power terminals) and seals.

Technical barriers to Low-voltage connectors

  • Patent barriers: Overseas manufacturers due to the first-mover advantage, a number of core technologies have constituted patent barriers, new entrants to bypass the patent barriers to design, R & D and manufacturing will need to invest in new technology to explore higher costs.
  • Production and technical requirements: Low-voltage connectors need to have good electrical conductivity, reliable contact performance and strong durability, automotive Low-voltage connectors require high-precision manufacturing process to ensure the stability and reliability of the connector. This includes precise mold design, high-quality material selection and strict production control processes.
  • Design and R & D capabilities: with the development of automotive electronics, intelligent, Low-voltage connectors need to continuously adapt to new technologies and application requirements. This requires companies to have a strong design and R & D capabilities, can continue to introduce new products to meet market demand.
  • Environmental protection and sustainability requirements: With the global environmental awareness, Low-voltage connectors need to meet environmental protection and sustainability requirements in the manufacturing and use process. This includes reducing the use of hazardous substances, improve product recyclability, reduce energy consumption. Enterprises need to invest in research and development resources to develop new materials and new technologies that meet environmental standards.

High-voltage connectors

It mainly meets the needs of motorization and consists of components such as terminals, seals, plastic parts and die-cast parts.

Technical barriers to high-voltage connectors

  • Balancing current-carrying capacity and temperature rise. High-voltage connector generated heat and current have a relationship, the higher the current generates more heat, the general requirements of the temperature rise increment can not be higher than 50 degrees, the total temperature reaches 105 degrees will be cut off, but some car manufacturers will limit the current at 90 degrees, so in fact, can not be a high sustained use of high power charging. How to maintain the current-carrying capacity to improve, but not let the temperature rise increment is too large in the design of the main consideration. Cooling is mainly considered in the connector products with and liquid cooling device.
  • EMC ;
  • Anti-stress relaxation, thermal stress relaxation;
  • High voltage protection design;
  • Design simulation test capabilities;
  • High vibration requirements.

High-speed connectors

Meet the needs of automotive assisted driving, intelligent driving, and car networking. The classification of automotive high-speed connectors can be divided into: Fakra (male + female), MiniFakra, Ethernet connectors, HSD connectors. Camera will use Fakra, MiniFakra, T-Box to domain control will use Ethernet and HSD, LIDAR will use Ethernet connector, head-up display will use differential connector.

Technical barriers to High-speed connectors

  • Electromagnetic and microwave convenience performance requirements, including impedance, EMC, touch-wave ratio, return loss, etc.
  • Thermal stress relaxation, stress relaxation resistance and other terminal design requirements.
