Generally speaking, it includes low-frequency circular connectors, radio frequency coaxial connectors, and audio connectors, etc. The cylindrical structure of the circular connector has natural firmness and higher strength than any other shape.

By rotating the screw rods on the housing, the screw rods can drive the anti-slip blocks to be respectively in contact with the upper and lower ends of the cable, which can improve the firmness of the connection between the cable and the circular connector body and is not easily separated when accidentally pulled by an external force. The anti-slip blocks can increase the contact surface and friction between the screw rods and the cable, and the sealing gasket can fill the gap between the cable and the housing, improving the sealing performance of the housing, which is convenient and practical.

[0004] However, the existing circular connectors can only withstand a voltage of AC 1.5 KV / min and cannot meet the requirement that the voltage withstands instantaneously reaches a peak value of 9 KV during the re-pulse of the PFA operation, resulting in poor applicability. Therefore, it does not meet the existing requirements, and for this reason, we propose a high-voltage-resistant circular connector. Content of the Utility Model
