[0020] As Figure 1 , Figure 3 and Figure 4 shown, a low-loss quick-insert optical fiber connector includes an inner connection component 1. An anti-bending component 2 is arranged outside the inner connection component 1. The anti-bending component 2 includes an anti-bending ring 201, a rotating head 202, a screw 203, a C-shaped block 204 and a pressing block 205. A rotating head 202 is installed at the upper end inside the anti-bending ring 201. The lower end of the rotating head 202 is connected to a screw 203. The screw 203 is externally connected to a C-shaped block 204. The lower end of the C-shaped block 204 is connected to a pressing block 205.

[0021] Through the threaded connection between the screw 203 and the C-shaped block 204, the extrusion force of the pressing block 205 on the inner connection component 1 can be adjusted. When the pressing block 205 is loosened, the anti-bending ring 201 can move on the inner connection component 1, so as to adjust the distance between each anti-bending ring 201. By adjusting the distance between the anti-bending rings 201, the maximum bendable angle of the inner connection component 1 is controlled, so that the device has a limiting effect, and the device can adjust the bendable length according to the use environment, which is convenient for the installation of the device and can also protect the inner connection component 1 to avoid bending damage to the inner connection component 1.

[0022] As Figure 2 shown, the right side of the inner connection component 1 is connected to an outer connection component 3. A locking component 4 is arranged outside the outer connection component 3.

[0023] As Figure 2 shown, the inner connection component 1 includes a first optical fiber line 101, a fixed outer block 102 and a first connector 103. The fixed outer block 102 is connected to the outside of the first optical fiber line 101. The right end of the first optical fiber line 101 is connected to a first connector 103.

[0024] As Figure 2As shown, the external connection component 3 includes an external connection head 301 and a first spring 302, and the first spring 302 is arranged inside the external connection head 301. The external connection component 3 further includes a second optical fiber line 303 and a second connection head 304, and the second optical fiber line 303 is arranged inside the first spring 302. The left end of the first spring 302 is connected to the second connection head 304;

[0025] Through the outer ring 401, the fixed outer block 102 can be locked, so that the first connection head 103 cannot move anymore after installation. At this time, relying on the elastic structure formed between the second connection head 304 and the external connection head 301 through the first spring 302, the external connection head 301 will be continuously pushed, so that the external connection head 301 is in close butt joint with the first connection head 103, thus facilitating the stability of equipment connection and the data transmission of optical fibers.

[0026] As Figure 2 shown, the locking component 4 includes an outer ring 401, a second spring 402 and a sliding ring 403, and the second spring 402 is arranged inside the outer ring 401. The left end of the second spring 402 is connected to the sliding ring 403. The locking component 4 further includes a mounting block 404 and an L-shaped block 405, and the mounting block 404 is connected to the left side of the sliding ring 403. The left side of the mounting block 404 is rotatably connected to the L-shaped block 405;

[0027] Relying on the sliding structure formed between the sliding ring 403 and the outer ring 401 through the second spring 402 to pull the mounting block 404, so that part of the L-shaped block 405 is pulled into the outer ring 401, so that the outer ring 401 clamps and fixes the outer block 102.

[0028] Working principle: When using this low-loss quick-connect fiber optic connector, first, the L-shaped block 405 is pulled outwards through the sliding structure between the slip ring 403 and the outer connector 301. Then, the four mounting blocks 404 are turned outwards through the rotating structure formed between the L-shaped block 405 and the mounting block 404. Then, the operator inserts the first connector 103 into the outer connector 301, so that the second connector 304 is docked with the first connector 103. Relying on the elastic structure formed between the second connector 304 and the outer connector 301 through the first spring 302, the second connector 304 can be continuously pushed, so that the connection between the second connector 304 and the first connector 103 is maintained stably until the operator inserts the fixed outer block 102 into the outer connector 301. At this time, the operator releases the L-shaped block 405. Relying on the sliding structure formed between the slip ring 403 and the outer ring 401 through the second spring 402, the mounting block 404 is pulled, so that a part of the L-shaped block 405 is pulled into the outer ring 401, so that the outer ring 401 catches the fixed outer block 102, ensuring the stable connection between the first connector 103 and the second connector 304, so that the device connection is successful, and the first optical fiber line 101, the first connector 103, the second connector 304 and the second optical fiber line 303 form a whole, thus ensuring the operation of the device. Then, the operator turns the rotating head 202 with a screwdriver, so that the rotating head 202 drives the screw 203 to rotate. Thus, through the threaded connection between the screw 203 and the C-shaped block 204, the C-shaped block 204 drives the pressing block 205 to rise, so that the pressing block 205 is loosened from the first optical fiber line 101, and the anti-bending ring 201 slides on the first optical fiber line 101, so as to adjust the distance between the anti-bending rings 201, so that the distance between the anti-bending rings 201 conforms to the bending angle of the first optical fiber line 101. When the adjustment of the anti-bending ring 201 is completed, turn the rotating head 202 again, so that the pressing block 205 presses the first optical fiber line 101 to fix the anti-bending ring 201.
