In some scenarios, it is necessary to determine which specific optical fiber at the far end corresponds to a certain port. Due to the large number of optical fibers, it is difficult for inspectors to directly determine which specific optical fiber corresponds to the far - end port. Currently, inspectors can use some online optical fiber identifiers on the market to identify optical fibers. The online optical fiber identifier can squeeze and bend the optical fiber to cause signal loss.

[0003] However, the optical fiber clamping function of some current online optical fiber identifiers on the market is relatively single, unable to adapt to different specifications of optical fibers, and the scope of use is relatively limited, resulting in low product applicability.

[0016] In some embodiments of the present utility model, the optical fiber clamp further includes a cover body which is disposed at the wire passing notch and connected to the housing. A wire inlet slot and an avoidance groove which are communicated with each other are formed between the cover body and the housing. The wire inlet slot is used to guide the optical fiber into the wire passing notch. The avoidance groove is used to provide an avoidance space when the optical fiber is extruded.

[0017] The beneficial effects of the present utility model are as follows: Different from the prior art, the fiber clamping device disclosed in the present utility model can be applicable to optical fibers of different specifications, greatly improving the applicability of the fiber clamping device.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0029] The present utility model provides a fiber clamping device. Referring to Figure 1 and Figure 2 , the fiber clamping device includes a housing 1 and a pressing member 2. Among them, the housing 1 is provided with at least two wire passing notches 11 for the optical fiber to pass through, and each wire passing notch 11 is communicated with the internal space of the housing 1. The housing 1 is further provided with at least two supporting portions 12, and each supporting portion 12 is arranged in a corresponding wire passing notch 11. The bending curvatures of the respective supporting portions 12 are different from each other. The number of the pressing members 2 is at least two, and each pressing member 2 is movably arranged in the housing 1. Each pressing member 2 is provided with a pressing portion 211. Each pressing member 2 moves when subjected to an external force, so that the pressing portion 211 approaches or moves away from the corresponding supporting portion 12, and the pressing portion 211 and the corresponding supporting portion 12 cooperate with each other to jointly press and bend the optical fiber.

[0030] Based on the above scheme setting, by arranging the extrusion member 2 inside the housing 1, when the proximal port of the optical fiber is placed at the wire passing notch 11, the extrusion member 2 moves towards the direction close to the support portion 12, and the extrusion portion 211 and the support portion 12 cooperate together to extrude and bend the optical fiber. The above operation is repeatedly performed during the detection process, so that the optical signal inside the optical fiber generates loss. The optical fiber identifier connected to the distal port of the optical fiber can measure which optical fiber inside generates the corresponding loss, thereby determining which optical fiber at the distal end of the optical fiber at this port is. This fiber clamping device has good bending stability, ensures the accuracy of detecting the optical fiber, improves the accuracy of optical fiber confirmation, is conducive to carrying out subsequent work, and this fiber clamping device is small in volume, easy to carry, and can also be operated with one hand. The operation is simple, reliable in use, conducive to reducing labor costs, and improving work efficiency.

[0031] Moreover, this fiber clamping device is at least provided with two wire passing notches 11, two support portions 12 and two extrusion members 2. With such a setting, this fiber clamping device can adapt to optical fibers of different specifications, which is convenient for dealing with the detection of optical fibers of different specifications in the computer room. Since there are a large number of optical fibers, by arranging multiple fiber clamping positions on this fiber clamping device, the number of optical fibers for detection and confirmation can be increased, the practicability is stronger, it is conducive to adapting to more different production conditions, reducing labor costs, and improving the work efficiency of detecting and confirming optical fibers.

[0032] In the embodiment of the present utility model, the support portion 12 and the corresponding extrusion portion 211 have the same bending curvature. With such a setting, during the process of extruding and bending the optical fiber, the bending stability of the optical fiber is ensured, so that the amount of each bending of the optical fiber can be controlled within a reasonable range, and the phenomenon that the optical fiber is bent too large or too small when repeatedly extruding the optical fiber can be effectively avoided, so as to improve the accuracy of detecting and confirming the optical fiber, and contribute to the development of subsequent work.

[0033] In one embodiment, at least two support portions 12 are convex structures, and at least two extrusion portions 211 are concave structures. For example, the support portion 12 can be a support convex block arranged in an arc shape. When the support portion 12 is a support convex block arranged in an arc shape, the extrusion portion 211 can be an extrusion groove, and the groove shape of the extrusion groove is adapted to the shape of the support convex block, so as to be able to bend and extrude the optical fiber.

[0034] It can be understood that in another embodiment, the support portion 12 can be a side wall groove. When the support portion 12 is a side wall groove, the extrusion portion 211 can be an extrusion convex block, and the groove shape of the side wall groove is adapted to the shape of the extrusion convex block, so as to be able to bend and extrude the optical fiber.

[0035] In the embodiment of the present utility model, the number of the wire passing notch 11, the support portion 12 and the extrusion member 2 is set to two. The two support portions 12 are respectively arranged at the corresponding wire passing notches 11, the number of the extrusion members 2 is set to two, and the two extrusion members 2 are arranged in one-to-one correspondence with the two support portions 12.

[0036] In the embodiment of the present utility model, the bending curvatures of at least two supporting parts 12 are different. With such a setting, during the process of squeezing and bending the optical fiber, the corresponding optical fibers are bent to different degrees, so that different losses are generated in the optical signals inside the optical fibers. The optical fiber identifier can measure that different losses are generated in the optical signals inside different optical fibers, thereby determining which optical fiber at the distal end corresponds to each port. The applicability is higher, which helps to improve the performance of the optical fiber clamping device.

[0037] In other embodiments, the bending curvatures of at least two supporting parts 12 can also be the same.

[0038] The housing 1 is arranged in a long strip shape. When squeezing and bending the optical fiber, the moving directions of at least two squeezing parts 2 on the housing 1 are opposite. With such a setting, on the one hand, it is beneficial to carry the optical fiber clamping device, and on the other hand, the optical fiber clamping device can squeeze and bend the optical fiber at both ends, which is convenient to operate, has better performance, and can well improve the operation efficiency.

[0039] Continue to refer to Figures 1 to 4 , the squeezing part 2 includes a squeezing body 21. A sliding groove 13 is formed on the inner side wall of the housing 1. A part of the squeezing body 21 is arranged in the sliding groove 13, and a squeezing portion 211 is formed at one end of the squeezing body 21 facing the supporting part 12.

[0040] Through the squeezing body 21, it is possible to cooperate with the supporting part 12 to squeeze the optical fiber mutually to complete the squeezing and bending of the optical fiber. Moreover, the squeezing body 21 is arranged in the sliding groove 13, which is beneficial to guiding the sliding of the squeezing body 21, so that the squeezing body 21 can slide stably and smoothly on the housing 1, improving the operation convenience and use reliability of the optical fiber clamping device, and thus enhancing the detection accuracy of the optical fiber.

[0041] The squeezing body 21 is provided with an operating part 212. The housing 1 is provided with a long through hole 14, and the long through hole 14 extends along the length direction of the housing 1. The operating part 212 passes through the long through hole 14 to extend outside the housing 1. The operating part 212 is used to drive the squeezing body 21 to move when acted by an external force. With such a setting, the operator can conveniently dial the operating part 212, and then drive the squeezing body 21 to move. This is not only convenient to operate, but also helps to improve the recognition efficiency of the optical fiber, thereby enhancing the work efficiency.

[0042] It can be understood that the operating part 212 can be a dialing convex block or a convex column, and the operating part 212 can also be a raised structure, as long as it can pass through the long through hole 14 and drive the squeezing body 21 when acted by an external force, and no specific limitation is made here.

[0043] Continue to refer to Figures 1 to 4, a first limiting portion 15 is provided on the groove wall of the sliding groove 13, and a second limiting portion 213 is provided on the extrusion body 21. The first limiting portion 15 and the second limiting portion 213 are in limiting cooperation to limit the moving stroke of the extrusion body 21 in the length direction of the housing 1.

[0044] With such a setting, the moving stroke of the extrusion body 21 on the housing 1 is limited by the first limiting portion 15 and the second limiting portion 213. On the one hand, the movement of the extrusion body 21 can be well controlled, effectively avoiding the phenomenon that the extrusion body 21 overly squeezes the optical fiber due to excessive force by the operator, resulting in damage to the optical fiber. On the other hand, the moving amplitude of the extrusion body 21 can be controlled within a certain range, which helps to save a certain amount of labor during repeated operations and improve the use reliability of the optical fiber clamp.

[0045] It can be understood that the first limiting portion 15 can be a limiting block. When the first limiting portion 15 is a limiting block, the second limiting block can be a limiting groove. The limiting block extends into the limiting groove, and the two groove walls of the limiting groove in the length direction of the housing 1 are respectively in stop cooperation with the limiting block to realize the limiting cooperation between the extrusion body 21 and the housing 1.

[0046] In another embodiment, the first limiting portion 15 can be a limiting groove. When the first limiting portion 15 is a limiting groove, the second limiting block can be a limiting block. The limiting block extends into the limiting groove, and the two groove walls of the limiting groove in the length direction of the housing 1 are respectively in stop cooperation with the limiting block to realize the limiting cooperation between the extrusion body 21 and the housing 1.

[0047] The extrusion body 21 has an initial position and a terminal position. At the initial position, the extrusion body 21 releases the optical fiber; at the terminal position, a gap is provided between the extrusion portion 211 and the support portion 12. That is, when no optical fiber is placed, a gap is provided between the extrusion portion 211 and the support portion 12. Whether there is an optical fiber placed or not, a gap is always left between the extrusion portion 211 and the support portion 12. With such a setting, on the premise of ensuring that the optical fiber can be squeezed and bent, it is ensured that the extrusion body 21 will not overly squeeze the optical fiber, so as to avoid damage or breakage of the optical fiber, thereby effectively protecting the optical fiber and improving the use performance of the optical fiber clamp.

[0048] Continue to refer to Figures 1 to 4 , the extrusion body 21 further includes a mounting body 22. The mounting body 22 has a mounting portion 221 and a guiding portion 222. The mounting portion 221 is fixedly installed with the housing 1, the guiding portion 222 extends along the length direction of the housing 1, the guiding portion 222 is slidably connected with the extrusion body 21, and the guiding portion 222 is used for guiding and guiding the movement of the extrusion body 21.

[0049] Since the fiber clamp is used in a manually operated manner, when the extrusion body 21 is driven to move by toggling the operating part 212, the extrusion body 21 can be guided by the guide part 222 so that the extrusion body 21 can move stably relative to the shell 1, further increasing the movement stability of the extrusion body 21 and effectively avoiding the possibility of the extrusion body 21 getting stuck or shaking during the movement.

[0050] The mounting portion 221 and the guide portion 222 can be integrally formed, and the mounting portion 221 can be fixed to the housing 1 by screws, or can be fixed to the housing 1 by snap-fit ​​connection, or can be fixed by plugging. The mounting portion 221 can also be fixedly connected to the housing 1 by other connection methods, which are not listed here one by one.

[0051] The extrusion body 21 is provided with a guide channel 214, and the guide portion 222 extends into the guide channel 214, so as to achieve sliding cooperation between the guide portion 222 and the extrusion body 21. There can be multiple guide portions 222, and accordingly, the number of the guide channels 214 is set corresponding to the multiple guide portions 222, so as to further improve the movement stability of the extrusion body 21 and the reliability of the fiber clamp.

[0052] Continue to refer to Figures 1 to 4 The fiber clamp also includes a cover body 3, which is arranged at the line-passing notch 11 and connected to the shell 1. The cover body 3 and the shell 1 are integrally formed, and a line-inlet seam 4 and an avoidance groove 5 that are connected to each other are formed between the cover body 3 and the shell 1. The line-inlet seam 4 is used to guide the optical fiber into the line-passing notch 11, and the avoidance groove 5 is used to provide an avoidance space when the optical fiber is squeezed.

[0053] With such an arrangement, the cover body 3 can be used to increase the constraint on the optical fiber, so that the optical fiber will not be displaced or flipped too much when under pressure. On the one hand, the optical fiber can be conveniently guided into the wire notch 11 through the wire entry seam 4, thereby improving the efficiency of placing the optical fiber to be tested. On the other hand, when the optical fiber is compressed and bent, the avoidance groove 5 provides an avoidance space for the optical fiber to be tested, so that the optical fiber to be tested can be better bent, effectively reducing the possibility of optical fiber damage to protect the optical fiber.

[0054] Among them, the shell 1 may include a shell body 16 and a cover plate 17, and the cover plate 17 and the shell body 16 can be fixed by screw connection or snap connection. The shell body 16 and the cover plate 17 can facilitate the installation of the extrusion part 2 and also facilitate disassembly to facilitate subsequent maintenance of the fiber clamp.

[0055] The above are only alternative embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
