What are the standards for wire harness connectors? How to design wire harness connector?

Wiring harness connector is a kind of connector for connecting wiring harness and equipment, which is widely used in automotive, aviation, medical, communications, industrial automation and other fields. The design of the harness connector needs to follow the relevant standards, and be designed according to the application scenarios, the number of connecting harnesses, the size, the working environment and other factors. Harness connector standards and design are described in detail below. 1.Harness connector standard The design and manufacture of harness connectors need to follow relevant standards to ensure their quality and reliability. The following are some commonly used wiring harness connector standards: (1) ISO 15170 standards: for the wiring harness connector in the automotive field, the size, shape, electrical parameters and other requirements of the connector are specified. (2) MIL-DTL-38999 Standard: For wiring harness connectors in the military and aerospace fields, it specifies the requirements for the physical characteristics, electrical characteristics, environmental adaptability, etc. Of the connectors. (3) IEC 61984 standard: for the wiring harness connector in the field of industrial automation, it specifies the requirements for the shape, size, electrical parameters, environmental adaptability, etc. Of the connector. (4) GB/T 14048.4 standard: for the wiring harness connector in the field of electrical control equipment, it specifies the requirements for the size, electrical parameters and environmental adaptability of the connector. 2. Design of harness connector The design of harness connector needs to consider many factors, including the number, size and working environment of the connecting harness. Here are some key points to design the harness connector: (1) Connector shape: The shape of the harness connector should be adapted to the shape of the connecting harness to ensure the quality of the connection between the connector and the harness. (2) Connection mode: The connection mode of the harness connector can be divided into plug-in type, buckle type, crimping type, etc., and the appropriate connection mode shall be selected according to the actual needs. (3) Contact material: The contact material of the harness connector shall be high-quality material to ensure the stability and reliability of the connector. (4) Sealing design: The harness connector shall have good sealing performance to prevent the external environment from affecting the connector. (5) Anti-corrosion: The harness connector shall be made of anti-corrosion materials to ensure the service life and reliability of the connector.
