Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber connectors, and in particular relates to an optical fiber connector with good waterproof effect. Background Art

[0002] Fiber optic connectors are devices that provide detachable connections between optical fibers, allowing the two end faces of the optical fibers to be precisely docked. They are widely used in telecommunication networks, data transmission networks, and enterprise local area networks.

[0003] For example, a Chinese document (CN215833650U) discloses a waterproof structure for an optical fiber connector, comprising an active connector, a passive connector movably installed inside the active connector, a limiting ring fixedly installed on the rear side of the active connector, a fixing strip fixedly installed on the inner side of the limiting ring, a contraction zone provided on the side of the fixing strip, and a fixing block fixedly installed on the inner side of one end of the fixing strip. In this waterproof structure for an optical fiber connector, since the diameter of the moving ring is smaller than the diameter of the limiting ring, the moving ring will not fall off from one end. When the moving ring moves toward one end, the fixing strip will gradually contract inside, so that the contraction zone on the side of the fixing strip will gradually shrink, so that each fixing strip will fit tightly, so that moisture will not penetrate. When one end of the fixing strip contracts inwardly, the fixing block can be simultaneously contracted inwardly, so that the fixing block enters the fixing port, so that the connection between the active connector and the passive connector can be protected and rainwater can be prevented from entering, and finally the purpose of good waterproof effect is achieved. However, after a long time, the inner peripheral side of the moving ring of the device will produce certain wear, which will affect the connection stability of the device, and then affect the connection sealing effect and signal transmission effect of the device. Therefore, certain improvements are needed. Utility Model Content
