What are the connector design specifications? How to design connector structure?

Connector is one of the most important components in electronic equipment, which is responsible for connecting different circuit boards, transmitting signals and data, etc. The purpose of connector design specification is to ensure the quality and stability of connectors in the process of production and use, and to improve product reliability and production efficiency. The following are some common connector design specifications and some basic steps for designing a connector structure. 1. Connector design specification 1. IPC specification IPC (Institute for Printed Circuits) is the abbreviation of International Printed Circuit Association, which is a professional organization dedicated to the development of printed circuit board and electronic assembly industry. IPC has developed a series of connector design specifications, including IPC-2220, IPC-2221, IPC-2222 and other standards, which specify the requirements of connector size, electrical performance, materials, connector design and so on. 2. MIL Specification MIL (Military Specification) is a standard formulated by the United States Military to regulate the design and production of military products. The MIL specification also has some requirements for connector design and performance, mainly including MIL-DTL-38999, MIL-DTL-5015, MIL-DTL-26482 and other standards. 3. IEC specification IEC (International Electrotechnical Commission) specification is a standard developed by the International Electrotechnical Commission, which is applicable to electrical and electronic technology worldwide. IEC specifications also have some requirements for the design and performance of connectors, mainly including IEC- 60603, IEC- 61076, IEC- 60950 and other standards. 2. Connector structure design The goal of connector structure design is to provide stable and reliable connection and good electrical performance. The structural design of the connector needs to be considered from the following aspects: 1. Size and shape The size and shape of the connector must be compatible with the connected circuit board or device to ensure that the connector can be completely embedded in the circuit board or device to achieve a solid connection. Also, the shape of the connector should be as small as possible to save space and cost. 2.Material The material of the connector shall be of sufficient strength and durability to ensure that the connector will not become loose or damaged during long-term use. Commonly used materials include copper, aluminum, steel, plastic, and rubber. 3. Joint design The joint design of the connector is an important factor in determining the quality of the connection. Proper connector design ensures that the connector transmits signals stably and reliably in different environments.
