[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings of the specification.

[0022] Embodiment

[0023] Figures 1 - 4 In this embodiment, the J599 type surface-contact high-density beam-expanding fiber optic connector includes a connector socket 10 and a connector plug 20. The connector socket 10 and the connector plug 20 are plugged and matched with each other. A screw sleeve 30 is rotatably sleeved on the surface of the connector plug 20. A thread corresponding to the screw sleeve 30 is provided on the surface of the connector socket 10. An anti-detachment assembly 50 is provided between the screw sleeve 30 and the connector plug 20;

[0024] The anti-detachment assembly 50 includes a ratchet wheel 51 and a plurality of moving blocks 53. A pawl 52 is rotatably inserted into the surface of the moving block 53. A torsion spring is provided between the moving block 53 and the pawl 52. One end of the pawl 52 is rotatably inserted into the ratchet wheel 52.

[0025] After connecting the connector socket 10 and the connector plug 20 with the screw sleeve 30, the provided anti-detachment assembly 50 can block the reverse rotation path of the screw sleeve 30. The screw sleeve 30 can only rotate unidirectionally in the tightening direction, avoiding loosening of the connector socket 10 and the connector plug 20 caused by the rotation of the screw sleeve 30 under external force, thereby ensuring the connection effect between the connector socket 10 and the connector plug 20.

[0026] Figures 1 - 2 In this embodiment, a limiting insertion rod 54 is movably inserted into the middle of the moving block 53. One end of the limiting insertion rod 54 is fixedly connected to the connector socket 10, and an elastic block 55 is provided at the end of the limiting insertion rod 54. The elastic block 55 is located between the connector socket 10 and the pawl 52. A push rod 56 is provided at the other end of the limiting insertion rod 54.

[0027] A closing piece 40 is fixedly connected to the end of the screw sleeve 30. One end of the push rod 56 is rotatably inserted into the closing piece 40, and the push rod 56 is threadedly sleeved with the closing piece 40.

[0028] By the push of the push rod 56, the moving block 53 drives the pawl 52 to leave the position of the ratchet wheel 51, canceling the restriction of the anti-detachment assembly 50 on the screw sleeve 30. The screw sleeve 30 can be rotated reversely to remove the connector plug 20, and the operation process is simpler and more convenient to use.

[0029] Figure 4 In this embodiment, the limiting insertion rod 54 is polygonally arranged, and the insertion part of the moving block 53 matches it.

[0030] The limiting insertion rod 54 that is polygonally arranged can prevent the moving block 53 from rotating along with the pawl 52, thereby ensuring the blocking effect of the anti-detachment assembly 50 on the reverse rotation path of the screw sleeve 30 and preventing the screw sleeve 30 from being reversely pushed by external force.

[0031] Figures 1 - 2 Among them, a guiding block 61 is arranged on the surface of the connector plug 20, and a corresponding guiding groove 62 is formed in the middle of the ratchet wheel 51.

[0032] The arranged guiding block 61 and guiding groove 62 facilitate the positioning and insertion of the ratchet wheel 51. At the same time, the guiding block 61 and guiding groove 62 can limit the ratchet wheel 51 to prevent the ratchet wheel 51 from rotating along with the movement of the pawl 52.

[0033] Figure 3 Among them, a sealing ring 70 is arranged inside the connector socket 10, and the sealing ring 70 is used for sealing after the connector plug 20 and the connector socket 10 are inserted and matched.

[0034] The arranged sealing ring 70 can ensure the sealing performance of the docking surface between the connector plug 20 and the connector socket 10 after the connector plug 20 and the connector socket 10 are docked.

[0035] Figure 1 and Figure 3 Among them, an optical head assembly 80 is arranged inside both the connector socket 10 and the connector plug 20, and a plurality of beam expanding assemblies are arranged inside the optical head assembly 80.

[0036] After the connector socket 10 and the connector plug 20 are docked, the plurality of beam expanding assemblies inside the optical head assembly 80 form a plurality of signal transmission bodies.

[0037] Working principle: When docking the connector socket 10 and the connector plug 20, rotate the B-direction screw sleeve 30 so that it is threadedly sleeved on the surface of the connector socket 10. Due to the restriction of the guiding block 61 and guiding groove 62 on the ratchet wheel 51, the ratchet wheel 51 rotates in the B direction along with the screw sleeve 30. Since the limiting insertion rod 54 is polygonally arranged and the insertion part of the moving block 53 matches it, the plurality of pawls 52 slide on the tooth surface of the ratchet wheel 51 with the moving block 53 as the center. When the connector plug 20 is completely inserted into the connector socket 10, because the plurality of pawls 52 are inserted into the ratchet wheel 51, the reverse movement path of the screw sleeve 30 is blocked, and the screw sleeve 30 is restricted by the anti-drop-off assembly 50 to ensure that the connector socket 10 and the connector plug 20 will not fall off due to external force. When it is necessary to pull out the connector plug 20, rotate the push rod 56 to drive the moving block 53 to move, and the pawls 52 move away from the position of the ratchet wheel 51 and compress the elastic block 55. The anti-drop-off assembly 50 no longer restricts the screw sleeve 30, and the screw sleeve 30 can be rotated in the reverse direction to pull out the connector plug 20.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
