[0026] The embodiment of the present application discloses a fiber optic plug. Through the setting of the anti-folding structure 3, when the optical fiber connector 2 shakes up and down, the length between the first connected folding plate 301 and the second connected folding plate 304 in the anti-folding structure 3 will become longer or shorter, and will become inclined. By stretching the elastic force of the spring 303, the second connected folding plate 304 and the plate slide groove 305 can be restored to a horizontal state, and the shaking amplitude of the optical fiber connector 2 can be reduced, thereby preventing the cable on one side of the optical fiber connector 2 from bending and breaking, and improving the stability of optical signal transmission.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Embodiment 1: Reference Figure 1 and Figure 2 The optical fiber plug disclosed in the embodiment of the present application includes an anti-folding structure 3, which is arranged at the top and bottom of the external protective frame 1 and the optical fiber connector 2. The anti-folding structure 3 is used to reduce the bending degree of the cable. The anti-folding structure 3 includes a first continuous folding plate 301 and a second continuous folding plate 304. The second continuous folding plate 304 has a plate slide groove 305 on one side. A slide plate 302 is slidably arranged on the inner side of the plate slide groove 305. The slide plate 302 is fixedly arranged on the first continuous folding plate 301. On one side of the slide plate 302, a tension spring 303 is fixedly provided on one side of the tension spring 303, and a fixed support plate 306 is fixedly provided on the other end of the tension spring 303. The fixed support plate 306 is fixedly provided on one side of the second connecting folding plate 304. The ends of the first connecting folding plate 301 and the second connecting folding plate 304 that are away from each other are respectively rotatably provided with a second vertical plate 308 and a first vertical plate 307. The second vertical plate 308 is fixedly provided on the top of the optical fiber connector 2, and the first vertical plate 307 is fixedly provided on the top of the external protective frame 1.

[0029] When the optical fiber connector 2 shakes during use, the anti-folding structure 3 is used to reduce the shaking amplitude of the optical fiber connector 2. Taking the optical fiber connector 2 shaking downward as an example, the length between the first connected folding plate 301 and the plate slide groove 305 in the top anti-folding structure 3 will become longer, the tension spring 303 will be shortened, the slide plate 302 will slide on the inner side of the plate slide groove 305, the length of the first connected folding plate 301 and the slide plate 302 in the bottom anti-folding structure 3 will become shorter, and the tension spring 303 will be extended. Relying on the elastic force of the tension spring 303, the optical fiber connector 2 can quickly return to its original shape, reducing the deformation of the cable, thereby preventing the cable on one side of the optical fiber connector 2 from bending and damaging, and improving the stability of optical signal transmission.

[0030] It should be noted that, refer to Figure 1 and Figure 3 , both sides of the external protective frame 1 are provided with limiting slide grooves 101, the limiting slide grooves 101 are arc-shaped, and both sides of the optical fiber connector 2 are fixedly provided with limiting slide columns 201, and the limiting slide columns 201 are slidably set on the inner side of the limiting slide grooves 101, and one side of the optical fiber connector 2 is fixedly provided with an accordion shield 202, and the accordion shield 202 is fixedly set on the inner side of the external protective frame 1.

[0031] When the optical fiber connector 2 shakes, the limiting slide 201 will slide on the inner side of the limiting slide groove 101 to limit the shaking range of the optical fiber connector 2 and enable the optical fiber connector 2 to be connected to the optical fiber plug 5 at different angles. The accordion cover 202 is provided to protect the cables on one side of the optical fiber connector 2.

[0032] Embodiment 2:.

[0033] Reference Figure 1 and Figure 3 The fiber optic plug also includes a fiber optic plug 5, which is plugged into the other side of the fiber optic connector 2. The fiber optic plug 5 is suitable for being locked and connected with the fiber optic plug 5 through a fixed locking component 4, a movable locking component 6 and an auxiliary locking component 7.

[0034] The fixed locking assembly 4 and the movable locking assembly 6 can make the connection between the optical fiber connector 2 and the optical fiber plug 5 more stable, and the auxiliary locking assembly 7 can improve the security of the connection therebetween.

[0035] Reference Figure 1 , Figure 4 and Figure 6 The locking assembly 4 is symmetrically arranged at the top and bottom ends of the optical fiber connector 2, and the locking assembly 4 includes a first locking block 403, and the first locking block 403 is semicircularly arranged. Connecting short columns 4031 are fixedly arranged at both ends of the first locking block 403, and a torsion spring 4032 is fixedly arranged on the outer side of the connecting short column 4031. A storage shell 402 is rotatably arranged on the outer side of the connecting short column 4031, and the other end of the torsion spring 4032 is fixedly connected to the storage shell 402. A leveling block 405 is fixedly arranged on the outer side of the storage shell 402, and a leveling inclined surface 4051 is arranged on the top of the leveling block 405.

[0036] Among them, refer to Figure 1 , Figure 4 and Figure 5 The movable lock assembly 6 is symmetrically arranged at the top and bottom ends of the optical fiber plug 5. The movable lock assembly 6 includes a second locking block 601, which is semicircular. A connecting handle 603 is fixedly arranged on the outer side of the second locking block 601. Guide slide columns 602 are fixedly arranged on both sides of the connecting handle 603. A waist arc plate 608 is slidably arranged on the outer side of the guide slide column 602. A leveling block 609 is fixedly arranged on the outer side of the waist arc plate 608. A contact surface 6091 and a guide leveling surface 6092 are arranged on one side of the bottom end of the leveling block 609. A fixed frame arm 610 is fixedly arranged on the outer side of the waist arc plate 608. A base plate 611 is fixedly arranged on the bottom end of the fixed frame arm 610.

[0037] 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. As the optical fiber plug 5 slowly approaches the optical fiber connector 2, the leveling abutment 609 in the movable lock assembly 6 first contacts the first locking block 403 in the fixed locking assembly 4. Through the setting of the abutment surface 6091, the first locking block 403 is rotated, and the plane of the first locking block 403 is parallel to the optical fiber connector 2. Then, through the setting of the leveling surface 6092, the first locking block 403 can always remain parallel during the movement of the leveling abutment 609, so as to achieve the locking effect with the movable lock assembly 6.

[0038] The rotation of the first locking block 403 drives the connecting short column 4031 to rotate, and the rotation of the connecting short column 4031 drives the torsion spring 4032 to contract, so that the first locking block 403 can be restored to its original state by the elastic force of the torsion spring 4032.

[0039] While the state of the first locking block 403 changes, the second locking block 601 will contact the leveling block 405 and cause the second locking block 601 to rotate. As the second locking block 601 moves, the second locking block 601 will contact the top of the storage shell 402, so that the second locking block 601 and the first locking block 403 remain in a horizontal state, and the first locking block 403 and the second locking block 601 are combined into a whole circle, thereby achieving a locking effect for the fixed locking assembly 4 and the movable locking assembly 6, making the connection between the optical fiber connector 2 and the optical fiber plug 5 more stable during use.

[0040] Furthermore, a vertical frame 401 is fixedly provided at the bottom end of the storage shell 402, a supporting frame 404 is fixedly provided on one side of the vertical frame 401, the vertical frame 401 is fixedly connected to the optical fiber connector 2, and a protective shell 4033 is rotatably provided on the outer side of the connecting short column 4031, and the protective shell 4033 is fixedly provided on both sides of the storage shell 402.

[0041] The vertical support frame 401 is used to fix the storage shell 402 , the support frame 404 is used to limit the movement of the flattening block 609 to prevent the flattening block 609 from excessive movement, and the protective shell 4033 is used to protect the torsion spring 4032 .

[0042] In this embodiment, a first end seat 604 is rotatably provided at the top of the connecting handle 603, a return spring 605 is fixedly provided at the top of the first end seat 604, a second end seat 606 is fixedly provided at the other end of the return spring 605, a fixed seat component 607 is rotatably provided at the top of the second end seat 606, the fixed seat component 607 is fixedly provided at the top of the fixed frame arm 610, a base plate 611 is fixedly provided at the top of the optical fiber plug 5, and an arc slide groove 6081 is opened on one side of the waist arc plate 608.

[0043] When the second locking block 601 rotates, the connecting handle 603 will tilt upward, and the reset spring 605 will be compressed. When the second locking block 601 enters the storage shell 402, the second locking block 601 will return to its original state through the elastic force of the reset spring 605, so that the second locking block 601 is stuck in the storage shell 402.

[0044] When the optical fiber connector 2 and the optical fiber plug 5 need to be separated, the connecting handle 603 is pulled upward to rotate the second locking block 601 and the first locking block 403, and the second locking block 601 is rotated out from the inside of the storage shell 402, and then the live lock assembly 6 can be directly withdrawn, so that the second locking block 601 leaves the first locking block 403, thereby achieving the unlocking effect.

[0045] It should be noted that, refer to Figure 1 , Figure 3 and Figure 7 Auxiliary locking components 7 are arranged on both sides of the locking component 4, and the auxiliary locking components 7 include connecting rods 701, and the connecting rods 701 are fixedly arranged at the other end of the connecting short column 4031, and a hook plate 702 is fixedly arranged at the other end of the connecting rod 701, and a hook claw 703 is arranged at the other end of the hook plate 702, and vertical connecting plates 704 are rotatably arranged on both sides of the hook plate 702, and the vertical connecting plates 704 are fixedly arranged at the top of the optical fiber connector 2.

[0046] When the fixed locking assembly 4 and the movable locking assembly 6 are locked, the rotation of the connecting short column 4031 in the fixed locking assembly 4 will simultaneously drive the connecting rod 701 in the auxiliary locking assembly 7 to rotate, thereby causing the hook plate 702 and the hook claw 703 to tilt upward. When the first locking block 403 returns to its 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.

[0047] Embodiment three: Reference Figure 1 and Figure 8 A dustproof component is arranged on the outside of the external protective frame 1 and the optical fiber plug 5, and the dustproof component includes a first expansion plate 8 and a second expansion plate 801. The first expansion plate 8 is fixedly arranged at the top and bottom ends of the optical fiber plug 5, and the second expansion plate 801 is fixedly arranged on both sides of the optical fiber plug 5. A connecting pad 802 is fixedly arranged at the connection between the first expansion plate 8 and the second expansion plate 801, and the connecting pad 802 is made of rubber material. The dustproof component also includes a first fixed expansion plate 803 and a second fixed expansion plate 804. The first fixed expansion plate 803 is fixedly arranged on both sides of the external protective frame 1, and the second fixed expansion plate 804 is fixedly arranged at the top and bottom ends of the external protective frame 1.

[0048] When connecting the optical fiber connector 2 and the optical fiber plug 5, the first expansion plate 8 and the second expansion plate 801 in the dustproof assembly will contact the second fixed expansion plate 804 and the first fixed expansion plate 803, and make the first expansion plate 8 and the second expansion plate 801 expand, and the connecting cushion 802 will deform and stretch to ensure the connection stability between the first expansion plate 8 and the second expansion plate 801, and provide tension for the first expansion plate 8 and the second expansion plate 801, so that 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, preventing dust from entering the connection between the optical fiber connector 2 and the optical fiber plug 5, thereby improving the safety performance of optical fiber transmission.

[0049] Working principle: When connecting the optical fiber connector 2 and the optical fiber plug 5, the optical fiber connector 2 and the optical fiber plug 5 are in the same horizontal state. As the optical fiber plug 5 slowly approaches the optical fiber connector 2, the leveling abutment block 609 in the movable lock assembly 6 first contacts the first locking block 403 in the fixed locking assembly 4. The abutment surface 6091 is set to make the first locking block 403 rotate and make the plane of the first locking block 403 parallel to the optical fiber connector 2. Then, the leveling abutment surface 6092 is set to make the first locking block 403 always maintain a parallel state during the movement of the leveling abutment block 609, so as to achieve the locking effect with the movable lock assembly 6. At the same time, the rotation of the first locking block 403 will drive the connecting short column 4031 to rotate, and the rotation of the connecting short column 4031 will drive the torsion spring 4032 to contract, so that the first locking block 403 can be restored to its original state by the elastic force of the torsion spring 4032; When the state of the first locking block 403 changes, the second locking block 601 will contact the guide block 405 and make the second locking block 601 rotate. As the second locking block 601 moves, the second locking block 601 will contact the top of the storage shell 402, so that the second locking block 601 and the first locking block 403 remain in a horizontal state, and the first locking block 403 and the second locking block 601 are combined into a full circle. When the second locking block 601 rotates, the connecting handle 603 will tilt upward, and the return spring 605 will be compressed. When the second locking block 601 enters the storage shell 402, the second locking block 601 will return to its original state through the elastic force of the return spring 605, so that the second locking block 601 is stuck in the storage shell 402, so that the fixed locking assembly 4 and the movable locking assembly 6 achieve a locking effect, so that the connection between the optical fiber connector 2 and the optical fiber plug 5 is more stable. 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. When the first locking block 403 returns to its 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. When the optical fiber connector 2 and the optical fiber plug 5 need to be separated, the coupling handle 603 is pulled upward to rotate the second locking block 601 and the first locking block 403, and the second locking block 601 is rotated out from the inside of the storage shell 402, and then the live lock assembly 6 can be directly withdrawn, so that the second locking block 601 leaves the first locking block 403, thereby achieving the unlocking effect, which is simple and convenient to use, and the connection is stable; 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 component will contact the second fixed expansion plate 804 and the first fixed expansion plate 803, and make the first expansion plate 8 and the second expansion plate 801 expand, and the connecting cushion 802 will be deformed and stretched to ensure the connection stability between the first expansion plate 8 and the second expansion plate 801, and provide tension for the first expansion plate 8 and the second expansion plate 801, so that 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, preventing dust from entering the connection between the optical fiber connector 2 and the optical fiber plug 5, thereby improving the safety performance of optical fiber transmission.

[0050] When the optical fiber connector 2 shakes during use, the anti-folding structure 3 is used to reduce the shaking amplitude of the optical fiber connector 2. Taking the optical fiber connector 2 shaking downward as an example, the length between the first connected folding plate 301 and the plate slide groove 305 in the top anti-folding structure 3 will become longer, the tension spring 303 will be shortened, the slide plate 302 will slide on the inner side of the plate slide groove 305, the length of the first connected folding plate 301 and the slide plate 302 in the bottom anti-folding structure 3 will become shorter, and the tension spring 303 will be extended. Relying on the elastic force of the tension spring 303, the optical fiber connector 2 can quickly return to its original shape, reducing the deformation of the cable, thereby preventing the cable on one side of the optical fiber connector 2 from bending and damaging, and improving the stability of optical signal transmission.
