Description

Technical Field

[0001] This utility model relates to the field of fiber optic operation and maintenance technology, and more specifically, to an electric fiber clamp. Background Technology

[0002] In routine maintenance of optical fibers, fiber clamps are used to bend the fibers and, together with detection devices, to determine the optical signal condition in the fiber in order to identify fiber routing, fiber faults, etc.

[0003] Currently, most fiber clamps used in the industry employ a pre-defined arched structure, which, after clamping the fiber, creates a fixed, single bending curvature. While this static bending method can achieve basic optical signal detection, it has significant limitations in practical operation and maintenance. First, the fixed bending shape cannot simulate the dynamic stress changes that the fiber may experience in actual use, thus making it difficult to effectively detect intermittent faults or performance degradation that only occur under specific bending conditions or vibrations. Second, for certain weak or specific signal anomalies, static bending with a single curvature may not provide the most significant micro-bending sensitivity, leading to insensitive fault diagnosis or missed detection. Therefore, the diagnostic capabilities and maintenance efficiency of existing fiber clamps need further improvement when dealing with complex and hidden fiber optic line faults, and the industry urgently needs a fiber clamp capable of dynamically bending fibers. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide an electric fiber clamp to solve the problem of the inability to dynamically bend optical fibers.

[0005] The technical solution adopted by this utility model is an electric fiber clamp, comprising: Base; A first fiber clamping component is movably disposed on the base, and the first fiber clamping component has a first sidewall that abuts against the optical fiber when clamping the fiber. A second fiber clamping member is disposed on the base. The second fiber clamping member has a second sidewall disposed opposite to the first sidewall, and a fiber clamping channel for optical fiber to pass through is formed between the first sidewall and the second sidewall. A reciprocating mechanism is provided on the base and connected to the first fiber clamping member, used to drive the first fiber clamping member to reciprocate relative to the base, so that the first sidewall moves closer to or further away from the second sidewall. A pair of first fiber folding members are disposed on both sides of the first sidewall. The end of the first fiber folding member closer to the first sidewall is rotatably disposed on the first fiber clamping member, and the end of the first fiber folding member away from the first sidewall is connected to the first fiber clamping member through an elastic reset member. A pair of second fiber folding members are disposed on both sides of the second sidewall, opposite to the first fiber folding member, and one end of the second fiber folding member near the second sidewall is rotatably disposed on the second fiber clamping member; A fiber folding drive mechanism is provided on the base and connected to the second fiber folding component. The fiber folding drive mechanism is used to drive the second fiber folding component and configure the second fiber folding component as follows: when the first sidewall is close to the second sidewall and the fiber is jointly clamped, the second fiber folding component and the first fiber folding component jointly clamp the fiber segments located on both sides of the second sidewall. The second fiber folding component drives the first fiber folding component segments to swing back and forth relative to the first sidewall, so as to bend the fiber segments back and forth. The main control device is located on the base and is electrically connected to the fiber folding drive mechanism.

[0006] This solution employs a normally open fiber clamping channel design. During testing, a reciprocating mechanism brings the first sidewall close to the second sidewall, clamping the fiber together. Then, a fiber bending drive mechanism, along with the first and second fiber bending components, actively bends the fiber, reducing accidental stress and damage. After testing, the second fiber bending component swings back to both sides of the second sidewall, causing the elastic reset component to reset the first fiber bending component, achieving automatic straightening of the bent fiber section. This solution enables rapid and automatic straightening of the bent fiber section, reducing damage to the bent area. Furthermore, the fiber bending drive mechanism allows the second fiber bending component to swing back and forth, dynamically bending the fiber at a preset frequency, improving fiber diagnostic capabilities and maintenance efficiency.

[0007] In some embodiments, the fiber folding drive mechanism includes a pair of transmission rods that correspond one-to-one with the second fiber folding member and a telescopic drive member with a telescopic shaft. The telescopic drive member is disposed on the base and is electrically connected to the main control device. The first end of the transmission rod is hinged to the telescopic shaft, and the second end of the transmission rod is hinged to the end of the second fiber folding member away from the second sidewall. The telescopic shaft extends and retracts relative to the base, and drives the second fiber folding component through the transmission rod, so that the second fiber folding component swings back and forth relative to the first fiber clamping component.

[0008] In some embodiments, the telescopic shaft is equipped with a sensing element; The electric fiber clamp also includes a detector, which is electrically connected to the main control device; The sensor is configured to trigger the detector to generate a sensing signal when the telescopic shaft reciprocates to a preset position.

[0009] This solution, through the detector sensing element, can improve the controllability of the telescopic shaft's extension and retraction, which helps to improve the operational stability and reliability of the electric fiber clamp.

[0010] Preferably, the telescopic shaft and the transmission rod are connected by a connecting seat, the connecting seat having a fastening part and two first hinge parts, the fastening part being fixedly connected to the telescopic shaft, and the first hinge parts being movably connected to the corresponding first end of the transmission rod; and / or, Each of the second fiber folding components has a second hinge portion on the side near the transmission rod, and the second hinge portion is movably connected to the second end of the corresponding transmission rod.

[0011] In some embodiments, the reciprocating mechanism includes a reciprocating movable device and a reciprocating actuating component connected together. The reciprocating movable device is disposed on the base, the first fiber clamping member is connected to the reciprocating movable device, and the reciprocating actuating component is exposed on the surface of the electric fiber clamping device for driving the reciprocating movable device to move the first sidewall closer to or away from the second sidewall.

[0012] The reciprocating mechanism of this solution has a simple structure, which helps to simplify the overall structural layout of the electric fiber clamp. It is also reliable and efficient in transmission, which is conducive to the rapid response of the reciprocating device to the operator's reciprocating operation.

[0013] In some embodiments, the reciprocating device includes a slider and a first spring. The slider is disposed on the base, the first fiber clamp is fixedly connected to the slider, a first end of the first spring is connected to the slider, and a second end of the first spring is connected to the base. The reciprocating control component is connected to the slider and is used to drive the slider so that the slider reciprocates relative to the base.

[0014] In some embodiments, the slider includes a first sliding portion and a second sliding portion movably disposed on the base, the first sliding portion and the second sliding portion are connected by a second spring member, the first fiber clamping member is fixedly connected to the first sliding portion, the first end of the first spring member is connected to the first sliding portion, and the reciprocating actuation member is connected to the second sliding portion.

[0015] Based on the elastic force of the second spring, this solution can adapt to optical fibers of different diameters when the first and second sidewalls clamp the optical fiber together, so that the first sidewall always presses the optical fiber against the second sidewall, thereby improving the clamping stability of the optical fiber.

[0016] In some embodiments, a guide shaft extending along the reciprocating direction of the reciprocating mechanism is also included, the guide shaft being disposed on the second fiber clamping member or the base; The first fiber clamping member is provided with a limiting hole for cooperating with the guide shaft.

[0017] In some embodiments, the reciprocating mechanism has a guide portion extending along the reciprocating direction of the reciprocating mechanism; The second fiber clamp or the base is provided with a limiting groove whose shape matches the guide portion.

[0018] In some embodiments, a locking device is also included for locking the reciprocating mechanism when the first sidewall is close to the second sidewall and clamps the fiber together, so that the reciprocating mechanism is in a locked state that restricts reciprocating movement; It also includes an unlocking component, which is used to release the locking state.

[0019] This solution uses a locking device to allow the first and second sidewalls to clamp the optical fiber for an extended period of time, freeing the operator's hands to perform other operations or record data stably. The unlocking device can release the clamping of the optical fiber by the first and second clamping components with a single click, restoring the fiber clamping channel to its normally open state.

[0020] In some embodiments, the electric fiber clamp further includes an optical power detection module electrically connected to the main control device, the optical power detection module being disposed on the base and exposed on the surface of the electric fiber clamp.

[0026] In some embodiments, the second sidewall has a mounting hole for mounting a light sensor facing the clamped optical fiber, and the light sensor is electrically connected to the main control device.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows: by actively bending the optical fiber through the cooperation of the fiber bending drive mechanism, the first fiber bending component, and the second fiber bending component, and based on the operation of the fiber bending drive mechanism, the optical fiber can be dynamically bent according to a preset frequency, thereby improving the optical fiber diagnostic capability and maintenance efficiency.

Detailed Implementation

[0034] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0035] Example 1 refer to Figure 1-5 This utility model provides an electric fiber clamp, comprising: Base 100; The first fiber clamping member 200 is movably disposed on the base 100, and the first fiber clamping member 200 has a first sidewall 210 that abuts against the optical fiber when clamping the fiber. The second fiber clamping member 300 is disposed on the base 100. The second fiber clamping member 300 has a second side wall 310 disposed opposite to the first side wall 210. A fiber clamping channel A for optical fiber to pass through is formed between the first side wall 210 and the second side wall 310. A reciprocating mechanism is provided on the base 100 and connected to the first fiber clamping member 200. It is used to drive the first fiber clamping member 200 to reciprocate relative to the base 100 so that the first side wall 210 moves closer to or further away from the second side wall 310. A pair of first fiber folding members 220 are disposed on both sides of the first sidewall 210. The end of the first fiber folding member 220 near the first sidewall 210 is rotatably disposed on the first fiber clamping member 200, and the end of the first fiber folding member 220 away from the first sidewall 210 is connected to the first fiber clamping member 200 through an elastic reset member. In a specific implementation, the first fiber folding member 220 is rotatably disposed on the first fiber clamping member 200 through a first rotating shaft. A pair of second fiber folding members 350 are disposed on both sides of the second side wall 310, opposite to the first fiber folding member 220. The end of the second fiber folding member 350 near the second side wall 310 is rotatably disposed on the second fiber clamping member 300. In a specific implementation, the second fiber folding member 350 is rotatably disposed on the first fiber clamping member 200 via a second rotating shaft. A fiber folding drive mechanism 500 is disposed on the base 100 and connected to the second fiber folding component 350. The fiber folding drive mechanism 500 is used to drive the second fiber folding component 350 and make the second fiber folding component 350 operate in the following manner: when the first side wall 210 is close to the second side wall 310 and jointly clamps the optical fiber, the second fiber folding component 350 and the first fiber folding component 220 jointly clamp the optical fiber segments located on both sides of the second side wall 310. Under the drive of the fiber folding drive mechanism 500, the second fiber folding component 350 drives the first fiber folding component to swing back and forth relative to the first side wall 210, so as to bend the optical fiber segments located on both sides of the second side wall 310. The main control unit 600 is located on the base 100 and is electrically connected to the fiber optic drive mechanism 500.

[0036] In addition, in order to straighten the bent fiber segment after the test is completed, when the first sidewall 210 is close to the second sidewall 310 to clamp the fiber together, the second fiber bending member 350 can also swing back to both sides of the second sidewall 310 and be flush with the second sidewall 310 under the drive of the fiber bending drive mechanism 500. As a result, the elastic reset member springs back the first fiber bending member 220, so that the first fiber bending member 220 presses the bent fiber segment toward the second fiber bending member 350 to straighten it.

[0037] refer to Figure 4 In order to detect light leakage signals in the bent fiber segment, in this embodiment, the second sidewall 310 is provided with a mounting hole, and a light sensor 320 facing the first sidewall 210 is installed in the mounting hole. The light sensor 320 is electrically connected to the main control device 600.

[0038] It is understood that the fiber clamping channel A of this utility model adopts a normally open design. In its natural state, the first sidewall 210 and the second sidewall 310 are far apart to form the fiber clamping channel A. When fiber clamping testing is required, the fiber to be tested can be easily and straightly placed into the predetermined position of the fiber clamping channel A. By applying external force to the reciprocating mechanism, the first sidewall 210 moves closer to the second sidewall 310 until they clamp the fiber together. Then, the main control device 600 operates the fiber folding drive mechanism 500, so that the second fiber folding member 350 continuously squeezes the fiber segments located on both sides of the second sidewall 310 toward the first fiber folding member 220. Thus, the first fiber folding member 220 overcomes the elasticity. The elastic stress of the reset member bends the optical fiber segment toward both sides of the first sidewall 210. This active control of optical fiber bending can reduce accidental stress on the optical fiber and reduce optical fiber damage. In addition, after the bending detection is completed, the main control device 600 manipulates the fiber bending drive mechanism 500 to make the second fiber bending member 350 swing back to a position flush with the second sidewall 310. At this time, the first fiber bending member 220 is not squeezed by the second fiber bending member 350. The elastic reset member can rebound the first fiber bending member 220 based on its own elastic force. Then, the first fiber bending member 220 presses the bent optical fiber toward the second fiber bending member 350 to straighten it, realizing the automatic straightening of the bent section of the optical fiber. Furthermore, when the first sidewall 210 is close to the second sidewall 310 to clamp the fiber together, the main control device 600 can also drive the fiber folding drive mechanism 500 to swing back and forth relative to the first sidewall 210 at a preset frequency. In this way, the fiber segment clamped between the first fiber folding component 350 and the second fiber folding component 220 can be bent back and forth dynamically at a preset frequency, thereby causing the fiber to bend and vibrate at a preset frequency.

[0039] In specific implementation, combined with Figure 5To understand this, the elastic reset element can be implemented using a torsion spring with two elastic arms. The main body of the torsion spring is sleeved on the structure of the first fiber clamping element 200 located behind the first fiber folding element 220, and the two elastic arms respectively abut against the rear of the first fiber folding element 220. It can be understood that when no external force is applied to the first fiber folding element 220, the first fiber folding element 220 is pushed to both sides of the first sidewall 210 by the elastic arms and becomes flush with the first sidewall 210. It is easy to understand that, in order to ensure that the first fiber folding member 220 is flush with the first sidewall 210, a limiting member can be provided on the first sidewall 210 or the first fiber folding member 220 to limit the swing amplitude of the first fiber folding member 220 relative to the first sidewall 210. Alternatively, some limiting structures can be provided between the first rotating shaft and the first fiber clamping member 200 to limit the swing direction of the first rotating shaft or the swing amplitude relative to the first sidewall 210. Other limiting methods can also be used to achieve the flush alignment of the first fiber folding member 220 with the first sidewall 210, which is readily understood by those skilled in the art and will not be elaborated upon here. Similarly, similar means can be used to ensure that the second fiber folding member 350 is flush with the second sidewall 310 when the optical fiber is not bent. Furthermore, since the second fiber folding member 350 is driven by the fiber folding drive mechanism 500, the second fiber folding member 350 can also be kept flush with the second sidewall 310 through the mechanical control of the fiber folding drive mechanism 500 itself. This is also a prior art method and will not be elaborated upon here.

[0040] refer to Figure 4 The fiber folding drive mechanism 500 includes a pair of transmission rods 510 that correspond one-to-one with the second fiber folding member 350 and a telescopic drive member 520 with a telescopic shaft 521. The telescopic drive member 520 is located on the base 100 and is electrically connected to the main control device 600. The first end of the transmission rod 510 is hinged to the telescopic shaft 521, and the second end of the transmission rod 510 is hinged to the end of the second fiber folding member 350 away from the second side wall 310. The telescopic shaft 521 extends and retracts relative to the base 100, and drives the second fiber folding component 350 via the transmission rod 510, causing the second fiber folding component 350 to swing back and forth relative to the first fiber clamping component 200. In specific implementation, the telescopic drive component 520 adopts a stepper motor to improve the accuracy and stability of telescopic control.

[0041] In some embodiments, the telescopic shaft 521 is provided with a sensing element 530; The electric fiber clamp also includes a detector, which is electrically connected to the main control unit 600; The sensor 530 is configured to trigger the detector to generate a sensing signal when the telescopic shaft 521 reciprocates to a preset position.

[0042] In use, the telescopic shaft 521 drives the sensing element 530 to reciprocate. The sensing element 530 passes through a detector, triggering the detector and generating a sensing signal. The main control device 600 obtains the position of the telescopic shaft 521 based on the sensing signal. When the sensing element 530 is in the position that triggers the detector, the main control device 600 can control the telescopic drive element 520 to drive the telescopic shaft 521 to stop at that position or start reciprocating motion from that position. It can be understood that by using the detector in conjunction with the sensing element 530, the controllability of the telescopic movement of the telescopic shaft 521 can be improved, which helps to improve the operational stability and reliability of the electric fiber clamp.

[0043] refer to Figure 4 The telescopic shaft 521 and the transmission rod 510 are connected by a connecting seat 540. The connecting seat 540 is provided with a fastening part and two first hinge parts. The fastening part is fixedly connected to the telescopic shaft 521, and the first hinge parts are movably connected to the first end of the corresponding transmission rod 510. The second fiber folding member 350 is provided with a second hinge part on the side near the transmission rod 510, and the second hinge part is movably connected to the second end of the corresponding transmission rod 510.

[0044] In a preferred embodiment, to simplify the structure, the sensing element 530 is disposed on the connecting base 540.

[0045] refer to Figure 3 The reciprocating mechanism includes a reciprocating moving device and a reciprocating operating component 410 connected to each other. The reciprocating moving device is located on the base 100. The first fiber clamping member 200 is connected to the reciprocating moving device. The reciprocating operating component 410 is exposed on the surface of the electric fiber clamper and is used to drive the reciprocating moving device so that the first fiber clamping member 200 moves closer to or away from the second fiber clamping member 300, thereby moving the first sidewall 210 closer to or away from the second sidewall 310.

[0046] In a specific implementation, in order to simplify the structure, the reciprocating motion device includes a slider 421 and a first spring 422. The slider 421 is disposed on the base 100, the first fiber clamping member 200 is fixedly connected to the slider 421, the first end of the first spring 422 is connected to the slider 421, and the second end of the first spring 422 is connected to the base 100. The reciprocating control component 410 is connected to the slider 421 and is used to drive the slider 421 so that the slider 421 reciprocates relative to the base 100.

[0047] It is understood that the reciprocating mechanism of this embodiment has a simple structure, which helps to simplify the overall structural layout of the electric fiber clamp, and the transmission is reliable and efficient, which is conducive to the reciprocating moving device responding quickly to the operator's reciprocating operation.

[0048] refer to Figure 3The sliding member 421 includes a first sliding part 423 and a second sliding part 424 movably disposed on the fiber optic detector base 100. The first sliding part 423 and the second sliding part 424 are connected by a second spring member 430. The first fiber clamping member 200 is fixedly connected to the first sliding part 423. The two ends of the first spring member 422 are respectively connected to the first sliding part 423 and the base 100. The reciprocating actuation member 410 is connected to the second sliding part 424.

[0049] It is understandable that when the first sidewall 210 and the second sidewall 310 clamp the optical fiber together, the second spring 430 can adapt to optical fibers of different diameters through its own elasticity, so that the first sidewall 210 always presses the optical fiber against the second sidewall 310, thereby improving the stability of the fiber clamping.

[0050] In some embodiments, the second fiber clamping member 300 is provided with a guide shaft 330 extending in the reciprocating direction of the reciprocating mechanism; the first fiber clamping member 200 is provided with a limiting hole 230 for passing through the guide shaft 330; in other embodiments, the guide shaft 330 may also be provided on the base 100.

[0051] In some embodiments, the reciprocating device has a guide portion 440 extending in the reciprocating direction of the reciprocating mechanism; the second fiber clamping member 300 is provided with a limiting groove 340 whose shape matches the guide portion 440; in other embodiments, the limiting groove 340 may also be provided on the base 100.

[0052] In some embodiments, a locking device 700 is also included for locking the reciprocating mechanism when the first sidewall 210 is close to the second sidewall 310 to clamp the fiber together, so that the reciprocating mechanism is in a locked state that restricts reciprocating movement. It also includes an unlocking component 710, which is used to release the locked state.

[0053] In use, when the first sidewall 210 is driven by the reciprocating mechanism to approach the second sidewall 310 and clamps the optical fiber together with the second sidewall 310, the reciprocating moving device of the reciprocating mechanism moves to contact the locking device 700. Thus, the locking device 700 restricts the reciprocating movement of the reciprocating moving device, allowing the first sidewall 210 and the second sidewall 310 to clamp the optical fiber for a long time. The operator can free their hands to perform other operations or record data stably. Furthermore, the first fiber clamping member 200 and the second fiber clamping member 300 can be released from clamping the optical fiber with one click through the unlocking member 710, so that the fiber clamping channel A returns to its normally open state.

[0054] In specific implementation, the locking device 700 can be implemented by means of a snap-fit ​​structure, a pin assembly, etc. The locking device 700 can also actively lock the reciprocating moving device, or enable the reciprocating moving device to achieve self-locking. These implementation methods are all existing technical means. Those skilled in the art can understand how the specific components are configured on the reciprocating moving device and the base 100, and will not be elaborated here.

[0055] In some embodiments, the motorized fiber clamp also includes an optical power detection module 110 electrically connected to the main control device 600. The optical power detection module 110 is located on the base 100 and exposed on the surface of the motorized fiber clamp. Specifically, the optical power detection module 110 includes a first port and an optical power meter probe connected to it. The optical power meter probe is installed on the base 100, and the first port is installed on the second exposed port. The first port can specifically adopt a standard fiber optic adapter, such as an SC / LC / FC interface. During testing, the end of the fiber to be tested is directly connected to the first port.

[0056] In some embodiments, the electric fiber clamp also includes a red light detection module 120 electrically connected to the main control device 600. The red light detection module 120 is located on the base 100 and exposed on the surface of the electric fiber clamp. Specifically, the red light detection module 120 includes a red laser diode located on the base 100 and a second port installed in the third exposed port. The red laser diode is connected to the second port. For example, the second port is implemented using an optical fiber interface. During detection, one end of a known good connecting optical fiber cable (patch cable) is inserted into the second port, and the other end is connected to the optical fiber link to be tested. The red laser diode emits visible laser light, which is injected into the optical fiber to be tested through the connecting optical fiber cable, thereby determining the connectivity of the optical fiber to be tested or locating the fault point of the optical fiber.

[0057] In some embodiments, a power supply module 130 for supplying power to the main control device 600 is also included, and the power supply module 130 is disposed on the base 100. Specifically, the power supply module 130 uses a rechargeable battery pack, and the base 100 has a fourth exposed port. The rechargeable battery pack is connected to an external power source for charging through a charging port located in the fourth exposed port. In other embodiments, the power supply module 130 may also be a power conversion module, a dry cell battery module, etc.

[0058] In some embodiments, the electric fiber clamp also includes a display module 140 electrically connected to the main control device 600, the display module 140 being exposed on the surface of the electric fiber clamp.

[0059] In some embodiments, the electric fiber clamp also includes operation keys 150 for operating the main control device 600, which are exposed on the surface of the electric fiber clamp. In specific implementations, depending on different functional requirements, several operation keys 150 are provided. In this embodiment, the telescopic drive 520, the light sensor 320, the light power detection module 110, and the red light detection module 120 are respectively controlled to open and close via different operation keys 150.

[0060] refer to Figure 2 In specific implementation, the base is provided with an upper opening C, which is closed by a cover 800. The cover 800 is provided with a break B that is connected to the fiber clamping channel A. The optical fiber to be clamped is placed into the fiber clamping channel A through the break B.
