What are circular electrical connectors?

Circular electrical connector is a kind of connector commonly used in electrical and electronic equipment, usually consists of two parts: plug and socket. Both the plug and the socket have a circular shape, and the plug can be inserted into the socket and tightly connected to it, thus realizing the connection of the circuit. Circular electrical connectors usually use a metal shell to protect the internal electrical contacts and can be provided with a level of protection to ensure the safety and reliability of the connector. Circular electrical connectors can be used in a variety of different applications, including industrial controls, communications equipment, military and aerospace. Different applications require different connector specifications and characteristics. Circular electrical connectors are designed and manufactured taking into account a variety of factors such as connector material, protection class, durability, sealing and mechanical properties to ensure that the connector maintains a high degree of reliability even under harsh environmental conditions. The appearance shapes of circular electrical connectors usually present different forms, such as cylindrical, rectangular, square, oval and so on. Each appearance shape has its specific applications and characteristics. In addition, the size of the connector is also available in a variety of specifications to suit different equipment requirements. The electrical properties of circular electrical connectors are also very important. These connectors must be able to operate stably under harsh environmental conditions such as high voltage, high temperature, high humidity and vibration. The electrical performance of circular electrical connectors is usually determined by the following aspects: 1. Rated voltage and rated current: these two parameters indicate that the connector can withstand greater voltage and current. 2. contact resistance: this parameter indicates the size of the resistance of the connector's internal electrical contacts, usually the smaller the better. 3. insulation resistance: this parameter indicates that the connector's internal insulation resistance between the different polarities, usually the larger the better. 4. Arc resistance: this parameter indicates that the connector can withstand the greater the arc energy inside. Circular electrical connectors have a wide range of applications in various fields, such as: 1. industrial control field: for robotics, automation systems, PLC and other equipment connection. 2. communication equipment field: for radio, satellite communications, network equipment, etc. connection. 3. military and aerospace fields: for missiles, fighter jets, helicopters, satellites, etc. connection.
