A coupler, also known as a connector, is a device used to connect two or more independent circuits or systems to achieve signal or power transmission. It usually consists of a plug and a socket, and the connection is achieved by insertion and locking. The plug, as part of the coupler, usually has a pin or a socket, which is used to contact the corresponding part in the socket to form a conductive path. The design of the coupler and the plug needs to consider many factors, including electrical performance, mechanical strength, environmental adaptability and safety, to ensure the reliability, stability and safety of the connection.
The working principle of the coupler is based on the principle of physical contact and conduction. When the pin or socket of the plug is in close contact with the corresponding part in the socket, a low-impedance conductive path is formed, allowing the signal or power to be transmitted smoothly. To achieve this goal, the coupler usually adopts the following key technologies.
Contact interface design: The contact interface is the key part of the coupler to achieve conductive connection. In order to ensure good contact performance, the pins and sockets of the coupler are usually made of highly conductive materials, such as copper alloy or gold-plated surface treatment. In addition, the shape, size and surface roughness of the contact interface must also be carefully designed to reduce contact resistance, prevent oxidation and corrosion, and improve the stability and durability of the connection.
Locking mechanism: In order to ensure that the coupler can maintain a stable connection under harsh environments such as vibration and impact, most couplers are equipped with a locking mechanism. These mechanisms include thread locking, snap locking, spring locking and other forms. Through the locking mechanism, the plug and the socket can fit tightly together to prevent accidental falling off or loosening.
Shielding and insulation: In the application of high-frequency signal transmission or high-voltage power transmission, the coupler must also have good shielding and insulation performance. The shielding layer can effectively block the influence of external electromagnetic interference on signal transmission; while the insulation layer can ensure that there will be no short circuit or leakage between the live parts, ensuring the safety of personnel and equipment.
As a part of the coupler, the working principle of the plug is similar to that of the coupler, and it focuses more on the matching with the socket and the smoothness of the insertion process. The design of the plug needs to consider the following aspects.
Matching: The pins or sockets of the plug must match the corresponding parts in the socket, including size, shape, arrangement, etc. Only well-matched plugs and sockets can form a stable conductive path to ensure the effective transmission of signals or power.
Insertion force: Insertion force refers to the resistance that needs to be overcome when the plug is inserted into the socket. Appropriate insertion force can not only ensure the reliability of the connection, but also avoid damage to the plug and socket. To achieve this goal, the pins of the plug are usually designed with a conical or beveled surface to reduce friction during insertion; at the same time, the sockets of the sockets also need to be optimized accordingly to ensure the smoothness of the insertion process.
Identification and polarity: In order to facilitate users to correctly connect and use the coupler and plug, polarity identification or function identification is usually marked on the plug. The polarity identification is used to indicate the positive and negative polarity or signal flow direction of the plug; while the function identification is used to distinguish different types of plugs and sockets to avoid mis-insertion or mixing.
