What Is a Circular Connector?
Circular connectors are specifically designed connectors, typically circular, used to connect cables that transmit electrical signals to devices.
As electronic devices handle various signals, including power, numerous wires corresponding to the signal types are required. The circular shape of these connectors facilitates easy connection when multiple thin wires are bundled together. A notable feature of circular connectors is their secure attachment, typically achieved through a screw-in cover that fastens them to the port.
Uses of Circular Connectors
Circular connectors are primarily utilized as terminals for connecting cables to electronic devices.
Their circular design, however, can pose challenges when accommodating a large number of wires, as the connector size increases and becomes more difficult to install and connect. In cases where numerous signals are involved, alternative solutions like elongated square connectors or D-sub connectors are often preferred. The choice between these connectors typically depends on the design and requirements of the equipment.
Additionally, circular connectors are also employed in connecting coaxial cables for high-frequency signal input.
Principle of Circular Connectors
For instance, transmitting images from a camera to a PC necessitates a dedicated signal line for image transmission, just as transmitting sound from a microphone requires a separate line for audio signals.
To simplify installation, these signal lines are often combined into a single cable with multiple twisted lines. Each line is soldered to specific pins on the connector, following a precise pin assignment. Correct pin assignment is critical, as errors can lead to severe issues, such as supplying voltage to communication lines, resulting in equipment damage. If a connected cable fails to operate equipment correctly, incorrect pin assignment is often the cause.
This way, by interconnecting cables and circular connectors, a comprehensive system is established, linking each device through these cables.
