[0044] When the optical fiber joint 2 and the optical fiber plug 5 are connected, the optical fiber joint 2 and the optical fiber plug 5 are in the same horizontal state, and as the optical fiber plug 5 slowly approaches the optical fiber joint 2, the flatness approaching block 609 in the movable lock assembly 6 first contacts the first lock block 403 in the fixed lock assembly 4. Through the arrangement of the abutting surface 6091, the first lock block 403 is rotated, and the plane of the first lock block 403 is in a parallel state with the optical fiber joint 2. Then, through the arrangement of the flatness guiding surface 6092, the first lock block 403 can always maintain a parallel state during movement, facilitating the locking effect of the movable lock assembly 6.

[0045] The rotation of the first lock block 403 drives the connecting short column 4031 to rotate, and the rotation of the connecting short column 4031 drives the torsional spring 4032 to contract, so that the first lock block 403 can rely on the elastic force of the torsional spring 4032 to recover to the original state.

[0050] When the second lock block 601 rotates, the connecting handle 603 will tilt upward, and the reset spring 605 will be compressed. When the second lock block 601 enters the storage shell 402, the second lock block 601 will be restored to the original state by the elastic force of the reset spring 605, so that the second lock block 601 is clamped into the storage shell 402.

[0051] When it is necessary to separate the optical fiber connector 2 and the optical fiber plug 5, the connecting handle 603 is pulled upward, so that the second lock block 601 and the first lock block 403 rotate, the second lock block 601 rotates out of the inside of the storage shell 402, and then the second lock block 601 can directly exit the live lock assembly 6, so that the second lock block 601 is away from the first lock block 403, and thus the unlocking effect can be achieved.

The dustproof assembly further includes a first fixed expansion plate 803 and a second fixed expansion plate 804, the first fixed expansion plate 803 is fixedly arranged at the two sides of the external protective frame 1, and the second fixed expansion plate 804 is fixedly arranged at the top end and the bottom end of the external protective frame 1.

[0056] When the optical fiber connector 2 and the optical fiber plug 5 are connected, the first expansion plate 8 and the second expansion plate 801 in the dustproof assembly are in contact with the second fixed expansion plate 804 and the first fixed expansion plate 803, and the first expansion plate 8 and the second expansion plate 801 are expanded, the connecting soft pad 802 is deformed and stretched, the stability of the connection between the first expansion plate 8 and the second expansion plate 801 is ensured, the first expansion plate 8 and the second expansion plate 801 can be provided with tension, the first expansion plate 8 and the second expansion plate 801 can be only attached to the second fixed expansion plate 804 and the first fixed expansion plate 803, dust is prevented from entering the connection between the optical fiber connector 2 and the optical fiber plug 5, and the safety performance of optical fiber transmission is improved.

[0057] Working principle: when the optical fiber connector 2 and the optical fiber plug 5 are connected, the optical fiber connector 2 and the optical fiber plug 5 are in the same horizontal state, the flatness block 609 in the live lock assembly 6 first contacts the first lock block 403 in the fixed lock assembly 4 when the optical fiber plug 5 slowly approaches the optical fiber connector 2, the first lock block 403 is rotated through the setting of the abutting surface 6091, and the plane of the first lock block 403 is parallel to the optical fiber connector 2, then the flatness block 609 can always keep the parallel state during movement through the setting of the flatness surface 6092, so that the locking effect of the live lock assembly 6 is achieved.

[0058] At the same time, the rotation of the first lock block 403 drives the connecting short column 4031 to rotate, and the rotation of the connecting short column 4031 drives the torsional spring 4032 to contract, so that the first lock block 403 can rely on the elastic force of the torsional spring 4032 to recover to the original state.

[0059] At the same time of the state change of the first lock block 403, the second lock block 601 contacts the flatness block 405 and rotates, and the second lock block 601 contacts the top of the receiving shell 402 during movement, so that the second lock block 601 keeps the horizontal state with the first lock block 403, and the first lock block 403 and the second lock block 601 form a whole circle, and at the same time of the rotation of the second lock block 601, the connecting handle 603 is inclined upward, and the return spring 605 is compressed, when the second lock block 601 enters the receiving shell 402, the second lock block 601 recovers to the original state through the elastic force of the return spring 605, so that the second lock block 601 is clamped into the receiving shell 402, and the fixed lock assembly 4 and the live lock assembly 6 achieve the locking effect, and the connection between the optical fiber connector 2 and the optical fiber plug 5 is more stable.

[0060] When the connecting short column 4031 rotates, the connecting rod 701 in the auxiliary lock assembly 7 is driven to rotate, and the hook plate 702 and the hook claw 703 are tilted upward and raised, and when the first lock block 403 returns to the original state, the hook claw 703 can hook the optical fiber plug 5, further improving the connection stability between the optical fiber connector 2 and the optical fiber plug 5.

[0061] When the optical fiber connector 2 and the optical fiber plug 5 need to be separated, the connecting handle 603 is pulled upward, the second lock block 601 and the first lock block 403 are rotated, the second lock block 601 rotates out of the inside of the storage shell 402, and the second lock block 601 directly exits the live lock assembly 6, so that the second lock block 601 is away from the first lock block 403, thus achieving the effect of unlocking, which is simple and convenient to use and stable in connection.

[0062] When the optical fiber connector 2 and the optical fiber plug 5 are connected, the first expansion plate 8 and the second expansion plate 801 in the dustproof assembly contact the second fixed expansion plate 804 and the first fixed expansion plate 803, and the first expansion plate 8 and the second expansion plate 801 are expanded, the connecting soft pad 802 is deformed and stretched, the connection stability between the first expansion plate 8 and the second expansion plate 801 is ensured, the first expansion plate 8 and the second expansion plate 801 can be provided with tension, the first expansion plate 8 and the second expansion plate 801 can only fit the second fixed expansion plate 804 and the first fixed expansion plate 803, dust is prevented from entering the connection between the optical fiber connector 2 and the optical fiber plug 5, and the safety performance of optical fiber transmission is improved.

[0063] When the optical fiber connector 2 shakes in use, the shaking amplitude of the optical fiber connector 2 is reduced through the anti-folding structure 3. Taking the case that the optical fiber connector 2 shakes downward as an example, the length between the first folding plate 301 and the plate sliding groove 305 in the top anti-folding structure 3 is lengthened, the tension spring 303 is shortened, the sliding plate 302 slides in the inside of the plate sliding groove 305, the length between the first folding plate 301 and the sliding plate 302 in the bottom anti-folding structure 3 is shortened, and the tension spring 303 is lengthened.
