Description
Technical Field
[0001] The present invention relates to the field of laser communication technology, and in particular to an optical fiber fixing device, laser communication equipment and an optical fiber fixing method. Background Art
[0002] Optical fiber is often used in laser communication equipment. Due to the small installation space in the chassis and the layout of the connection positions in the chassis, the optical fiber is often in a bent state when it is used. Optical fiber is very sensitive to stress. When the optical fiber is bent, it may cause the optical signal to escape through the optical fiber cladding. As the bend becomes sharper, the optical signal will also leak more. Therefore, the optical fiber should not be bent beyond its tolerable bending radius.
[0003] Currently, when assembling laser communication equipment, the two ends of the optical fiber are first connected to the corresponding connection positions in the chassis, and the bending degree of the optical fiber is manually adjusted. Then, the adhesive to be cured is filled into the chassis. After that, the adhesive to be cured is cured. On the one hand, when filling the adhesive to be cured, since the bending part of the optical fiber is not fixed, it is impacted by the flow of the adhesive, and the position of the bending part of the optical fiber is very easy to change, causing the bending of the optical fiber to become sharp. On the other hand, the number of optical fibers used reaches dozens. In the process of installing optical fibers one by one, if the human hand touches the bending part of the installed optical fiber, the position of the bending part of the optical fiber will also change, causing the bending of the installed optical fiber to become sharp.
[0004] Therefore, how to effectively prevent the position of the bending portion of the optical fiber from changing and avoid the bending of the optical fiber from becoming sharp becomes a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION
[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] As described in the background technology, when assembling laser communication equipment, first connect the two ends of the optical fiber to the corresponding connection positions in the chassis, and adjust the bending degree of the optical fiber manually. Then fill the chassis with glue to be cured. After that, cure the glue to be cured. On the one hand, when filling the glue to be cured, since the bending part of the optical fiber is not fixed and is impacted by the flow of the glue, the position of the bending part of the optical fiber is very easy to change, causing the bending of the optical fiber to become sharp. On the other hand, the number of optical fibers used reaches dozens. In the process of installing optical fibers one by one, if the human hand touches the bending part of the installed optical fiber, the position of the bending part of the optical fiber will also change, causing the bending of the installed optical fiber to become sharp. Therefore, how to effectively prevent the position of the bending part of the optical fiber from changing and avoid the bending of the optical fiber from becoming sharp has become a technical problem that needs to be solved urgently by those skilled in the art.
[0021] To solve the above problems, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 On the one hand, the present invention provides an optical fiber fixing device 100, including a substrate 110, a first fixed stop pin 120, a second fixed stop pin 130 and a movable stop pin 140. The substrate 110 is used to support the first fixed stop pin 120, the second fixed stop pin 130 and the movable stop pin 140. The first fixed stop pin 120 is fixedly installed on one side of the substrate 110. The second fixed stop pin 130 is fixedly installed on the other side of the substrate 110. The movable stop pin 140 is installed in the middle of the substrate 110 so as to be movable up and down and left and right. Before installing the optical fiber 300 in the chassis 200 of the laser communication equipment, as shown in FIG. Figure 5As shown, dozens of optical fibers 300 can be wound around the first fixed stop pin 120, the second fixed stop pin 130 and the movable stop pin 140 one by one to limit the bending parts of dozens of optical fibers 300. Afterwards, the optical fiber fixing device 100 and the optical fiber 300 carried on the optical fiber fixing device 100 are installed in the chassis 200. In this way, when the chassis 200 is filled with the glue to be cured and when the human hand accidentally touches the installed optical fiber 300, the position of the bending part of the optical fiber 300 is not easy to change, which avoids the bending of the optical fiber 300 from becoming sharp, thereby ensuring the communication effect. There is no need to specially customize different types of chassis 200 with the function of fixing the bending part, which is conducive to reducing the cost of the chassis 200. It has strong adaptability and is suitable for a variety of installation conditions. Moreover, the movable stop pin 140 can move left and right, and can flexibly adjust the bending degree of the optical fiber 300 according to the type of optical fiber 300 used, and can also move up and down, and can flexibly adjust the height of the top of the movable stop pin 140 according to the number of installation layers of the optical fiber 300.
[0022] Preferably, there are a plurality of first fixed stop pins 120 arranged in a row. There are a plurality of second fixed stop pins 130 arranged in a row; there are a plurality of movable stop pins 140 arranged in multiple rows. Each optical fiber 300 can be wound around one of the second fixed stop pins 130, one of the movable stop pins 140, the first fixed stop pin 120, another movable stop pin 140 and another second fixed stop pin 130 in sequence. The movable stop pin 140 is moved left and right with the help of human hands to adjust the local curvature and improve the communication effect.
[0023] Preferably, the plurality of movable stop pins 140 are arranged in two or three rows.
[0024] Preferably, if Figure 5 As shown, the distance between the straight line where a row of movable stop pins 140 near the first fixed stop pin 120 is located and the straight line where the first fixed stop pin 120 is located is L1. The distance between the straight line where a row of movable stop pins 140 near the first fixed stop pin 120 is located and the straight line where a row of movable stop pins 140 near the second fixed stop pin 130 is located is L2. The distance between the straight line where a row of movable stop pins 140 near the second fixed stop pin 130 is located and the straight line where the second fixed stop pin 130 is located is L3. L3>L2>L1. In this way, the local curvature of the optical fiber 300 can be better adjusted.
[0025] Specifically, in the exemplary embodiment, multiple rows of guide grooves are provided in the middle of the substrate 110. The optical fiber fixing device 100 further includes multiple stopper plugs 150, a rigid plate 160, a flexible sheet 170 and multiple stopper caps 180. Multiple stopper plugs 150 are screwed to the movable stopper pins 140 in a one-to-one correspondence with multiple movable stopper pins 140. Any stopper plug 150 can be snapped into the corresponding guide groove to limit the movement of the corresponding movable needle. When the movable stopper pin 140 rotates around its own axis, the height of the top of the movable stopper pin 140 can be adjusted. A glue storage tank 161 is formed on the top surface of the rigid plate 160, and the bottom surface abuts against the top surface of the substrate 110. The glue storage tank 161 is used to store the glue to be cured. A first clearance hole 162 for the first fixed stopper pin 120 to pass through, a second clearance hole for the second fixed stopper pin 130 to pass through, and a clearance groove 163 for the movable stopper pin 140 to pass through are provided on the rigid plate 160. It should be noted that before installing the optical fiber fixing device 100 and the optical fiber 300 mounted on the optical fiber fixing device 100 in the chassis 200, the glue storage tank 161 is first filled with glue to be cured, so as to further fix the optical fiber 300 and further prevent the position of the bending part of the optical fiber 300 from changing. The flexible sheet 170 is arranged between the bottom surface of the rigid plate 160 and the top surface of the substrate 110. It should be pointed out that when the flexible sheet 170 is installed on the top surface of the substrate 110, the position of each movable stop needle 140 is adjusted first, and then each first fixed stop needle 120, each second fixed stop needle 130 and each movable stop needle 140 pierce the flexible sheet 170, so that the bottom surface of the flexible sheet 170 and the top surface of the substrate 110 are mutually attached. With the help of the flexible sheet 170 and the rigid plate 160, the optical fiber 300 and the glue to be cured can be separated from the substrate 110 and the steel needle at one time, so that the substrate 110 and the steel needle can be reused, thereby reducing costs. At least one limiting cap 180 is screwed on one of the first fixed stop pins 120, at least one limiting cap 180 is screwed on one of the second fixed stop pins 130, and at least one limiting cap 180 is screwed on one of the movable stop pins 140. Before the glue storage tank 161 is filled with the glue to be cured, the limiting nut can be rotated so that the bottom surface of the limiting nut is pressed against the optical fiber 300 to limit the light from moving up and down.
[0026] Preferably, each stopper 150 is a rubber stopper that can be deformed to a certain extent to facilitate installation and removal of the stopper 150. A clamping protrusion is provided on the side wall of each stopper 150 to improve the clamping stability.
[0027] Preferably, the flexible sheet 170 is made of rubber, paper or cloth.
[0028] Preferably, an intercepting rod is provided on each limiting cap 180 , and the intercepting rod can be pressed against the optical fiber 300 .
[0029] Reference Figure 6On the other hand, the present invention also provides a laser communication device, comprising a chassis 200 and an optical fiber fixing device 100 provided in any of the above embodiments. The optical fiber fixing device 100 is installed in the chassis 200. Before installing the optical fiber 300 in the chassis 200 of the laser communication device, as shown in FIG. Figure 5 As shown, dozens of optical fibers 300 can be wound around the first fixed stop pin 120, the second fixed stop pin 130 and the movable stop pin 140 one by one to limit the bending parts of dozens of optical fibers 300. Afterwards, the optical fiber fixing device 100 and the optical fiber 300 carried on the optical fiber fixing device 100 are installed in the chassis 200. In this way, when the chassis 200 is filled with the glue to be cured and when the human hand accidentally touches the installed optical fiber 300, the position of the bending part of the optical fiber 300 is not easy to change, which avoids the bending of the optical fiber 300 from becoming sharp, thereby ensuring the communication effect. There is no need to specially customize different types of chassis 200 with the function of fixing the bending part, which is conducive to reducing the cost of the chassis 200. It has strong adaptability and is suitable for a variety of installation conditions. Moreover, the movable stop pin 140 can move left and right, and can flexibly adjust the bending degree of the optical fiber 300 according to the type of optical fiber 300 used, and can also move up and down, and can flexibly adjust the height of the top of the movable stop pin 140 according to the number of installation layers of the optical fiber 300.
[0030] On the other hand, the present invention also provides a method for fixing an optical fiber, comprising: first, moving the movable stop pin 140 up, down, left and right to adjust the height of the top of the movable stop pin 140 and the position of the movable stop pin 140. Then, the flexible sheet 170 is installed on the top surface of the substrate 110, and the rigid plate 160 is installed on the top surface of the flexible sheet 170. Next, each optical fiber 300 is wound around one of the second fixed stop pins 130, one of the movable stop pins 140, the first fixed stop pin 120, another movable stop pin 140 and another second fixed stop pin 130 in sequence. Afterwards, the glue storage tank 161 of the rigid plate 160 is filled with glue to be cured to fix the optical fiber 300. Next, the substrate 110, the flexible sheet 170 and the rigid plate 160 are installed in the chassis 200. Then, the glue to be cured is filled into the chassis 200. Finally, the glue to be cured is cured with the aid of ultraviolet rays. In this way, when the glue to be cured is filled into the chassis 200 or when the human hand accidentally touches the installed optical fiber 300, the position of the bending part of the optical fiber 300 is not easy to change, which prevents the bending of the optical fiber 300 from becoming sharp, thereby ensuring the communication effect. There is no need to specially customize different types of chassis 200 with fixed bending part functions, which is conducive to reducing the cost of the chassis 200. It has strong adaptability and is suitable for various installation conditions.
