What is the name of a circular connector?

1, Classification of circular connectors
Circular connectors can be divided into low-frequency circular connectors, RF coaxial connectors, and audio connectors according to the different transmission signals. Low frequency circular connectors are mainly used for transmitting low-frequency signals, such as control signals and data signals; RF coaxial connectors are used to transmit high-frequency signals, such as microwave and radio signals; The audio connector is specifically designed for transmitting audio signals.
In addition, circular connectors can be classified based on their card type, wiring method, plug shape, and other factors. Card types include 1/4 quick card connection, plug-in connection, latch connection, quick plug connection, threaded connection, zipper connection, etc; The wiring methods include crimping, welding, nut locking, casting cables, etc; The shape of the plug includes right angled and bent angled, as well as needle shaped circular aviation plugs and pinhole circular aviation plugs.
2, Structure and Function of Circular Connectors
The structure of a circular connector usually consists of a plug and a socket. The plug housing assembly consists of seven parts: housing, locking sleeve, spring plate, pin, steel ball, spring plate, and gasket. After the assembly of the lock sleeve and the shell, the pin is inserted into the shell and riveted onto the lock sleeve. There is a structure that can rotate 20 degrees between the lock sleeve and the shell. There are 3-4 steel balls inside the plug housing, which play a role in docking and locking. After insertion, the rotating locking sleeve supports the steel ball, protruding it from the inner wall of the housing and extending it into the annular groove on the socket housing to achieve the locking of the plug and socket.
This structure not only enables the circular connector to have the functions of anti skewed insertion and anti incorrect insertion, but also gives it excellent electrical and shielding performance. At the same time, circular connectors also have good vibration resistance, impact resistance, and environmental resistance. These characteristics have made it widely used in fields such as aerospace, military equipment, industrial automation, and communication equipment.
3, Performance characteristics of circular connectors
Environmental resistance: Circular connectors have excellent environmental resistance and can maintain stable connections under harsh weather conditions. Its shell is usually made of high-strength and corrosion-resistant materials, which can resist the influence of environmental factors such as humidity and temperature.
Anti vibration and anti impact: The locking mechanism of the circular connector is ingeniously designed, giving it excellent anti vibration and anti impact performance. Even under strong vibrations and impacts, it can maintain a stable connection state.
Shielding performance: Circular connectors usually have good shielding performance, which can effectively prevent electromagnetic interference and signal leakage. This is particularly important for devices that transmit sensitive signals.
Easy to operate: The locking and unlocking operation of the circular connector is simple and fast, just rotate the locking sleeve to complete. This makes circular connectors an ideal choice in limited spaces or situations where frequent plugging and unplugging are required.
4, Application areas of circular connectors
Circular connectors are widely used in various fields due to their multifunctionality and high performance
Aerospace: In the aerospace field, circular connectors are used in power and data transmission systems for aircraft, satellites, and other equipment. Its environmental resistance, vibration resistance, and impact resistance ensure the stable operation of the equipment under extreme conditions.
Military equipment: In military equipment, circular connectors are used in communication and control systems for heavy equipment such as tanks and armored vehicles. Its shielding performance and anti skew and anti mistake insertion functions ensure the accuracy and security of data transmission.
Industrial automation: In the field of industrial automation, circular connectors are used in power and data transmission systems for robots, automated production lines, and other equipment. Its easy operation and stable connection performance improve the reliability and production efficiency of the equipment.
Communication equipment: In communication equipment, circular connectors are used in signal transmission systems for base stations, antennas, and other devices. Its high-frequency performance and shielding performance ensure the quality and stability of signal transmission.
5, Selection and maintenance of circular connectors
When choosing a circular connector, the following points should be noted:
Choose the appropriate bayonet type and wiring method: Select the appropriate bayonet type and wiring method based on specific application scenarios and requirements. For example, in situations where frequent plugging and unplugging are required, circular connectors with quick plugging and unplugging connections can be chosen; In situations where high-frequency signals need to be transmitted, RF coaxial connectors can be chosen.
Pay attention to the size and weight of the connector: Choose the appropriate connector size and weight according to the installation space and weight requirements of the equipment. Ensure that the connector can be easily installed on the device and does not have a negative impact on the overall performance of the device.
Pay attention to the performance indicators of connectors: When selecting connectors, it is necessary to pay attention to their performance indicators, such as contact resistance, insulation resistance, dielectric strength, etc. Ensure that the selected connector meets application requirements and has high reliability and stability.
When maintaining circular connectors, the following points should be noted:
Regularly check the connection status of the connector: Regularly check the connection status of the connector to ensure that it is not loose or damaged. If any abnormal situation is found, it should be replaced or repaired in a timely manner.
Keep the connector clean and dry: Regularly clean the dust and dirt on the surface of the connector and keep its interior dry. Prevent the connector from being corroded by moisture and corrosive substances.
Avoid excessive insertion and twisting: When inserting or removing connectors, excessive force or twisting of the connectors should be avoided. To avoid damaging the structure of the connector or affecting its performance.
