The connector end has a plug-in portion for connecting electronic devices. The dustproof assembly includes a hollow dust cover, a spring, and a cover. One end of the dust cover is inserted into an annular groove at the connector end. An outer limiting slider slides against a limiting groove on the inner wall of the annular groove, ensuring its movement in a specific direction. A first mounting portion of the protruding outer part of the dust cover and a second mounting portion on the connector fix the spring, providing elasticity in its normal state, allowing the dust cover to protrude from the connector. The cover is detachably installed at the opening of the dust cover, covering the plug-in portion. This connector cable, through the cooperation of the dust cover and cover, effectively blocks dust and moisture from contacting the plug-in portion, avoiding poor contact caused by dust accumulation. During insertion and removal, the dust cover is compressed by external force and retracts along the limiting groove, without affecting use.
