What are the connector standards? How to choose the right connector?

Connectors are a very important part of electronic equipment and are used to connect different electronic components, devices or systems together. There are many different types of connectors, so it is very important to choose the right connector. At the same time, each also developed relevant standards to regulate the design and manufacture of connectors. Connector standards In China, the standard for connectors is GB/T 15288-2017 Electronic Components General Connectors. The standard specifies the connector's terminology and definitions, marking, materials, mechanical and electrical properties, reliability and other requirements, the production, inspection and use of connectors and other aspects are regulated in detail. In the international community, the connector standards are mainly the following: 1. ISO standards: the International Organization for Standardization (ISO) developed connector standards are mainly ISO 10487, ISO 11898, etc. 2. IEC standards: the International Electrotechnical Commission (IEC) developed connector standards are mainly IEC 61076, IEC 603-2, etc. 3. MIL standards: Connector standards developed by the U.S. Department of Defense, mainly applicable to military and aerospace fields. The correct choice of connector needs to consider a variety of factors, including the type of connector, specifications, materials, performance, etc. 1.Connector type: the types of connectors include board-to-board connectors, wire-to-board connectors, wire-to-wire connectors, and so on. It is very important to choose the right type of connector according to the actual needs. 2. Connector specifications: the specifications of the connector include connector size, number of pins, connector shape and so on. When choosing connectors, you need to consider the specifications of the equipment or components that match the connector.3. Connector material: connector materials usually include metal, plastic, etc., different materials have a great impact on the mechanical strength of the connector, electrical performance. In the selection of connectors need to consider the applicable environment, service life and other factors. 4. connector performance: connector performance, including electrical performance, mechanical properties, environmental adaptability. In the selection of connectors need to choose the appropriate performance indicators according to the actual needs. In practical applications, the correct choice of connector also needs to be considered according to the specific application scenarios. For example, for the need for waterproof and dustproof occasions, you can choose a connector with IP67 or higher protection level; for high-speed transmission occasions, you can choose a connector with a higher bandwidth and transmission rate.
