Description

Technical Field

[0001] This utility model relates to the field of optical fiber detection technology, and more specifically, to a fiber clamp. Background Technology

[0002] In routine fiber optic maintenance, fiber clamps are used to bend the fiber, and detection devices are used to assess the optical signal within the fiber to determine issues such as fiber routing and faults. The detection device primarily utilizes the macro-bending effect; by bending the target fiber, the transmitted optical signal is leaked, and the detection device detects this leaked signal, thus identifying and inspecting the fiber.

[0003] Existing fiber clamping tools can only bend optical fibers. After the inspection is completed, the bent part often cannot straighten itself. Over time, this can easily affect the transmission of optical fibers and even damage the bent part of the optical fiber. Utility Model Content

[0004] The present invention aims to overcome at least one of the defects of the prior art and provide a fiber clamp to solve the problem of difficulty in straightening optical fibers.

[0005] The technical solution adopted by this utility model is to provide a fiber clamp, comprising:

[0006] The housing includes a cover and a base connected together, the cover and the base forming a mounting cavity, the cover having a front opening communicating with the mounting cavity, and the base including a fiber-blocking member extending forward relative to the front opening, the fiber-blocking member having an arc-shaped portion protruding toward the front opening, the front opening being spaced apart from the arc-shaped portion;

[0007] A pair of swinging members are movably disposed on the base or the cover and positioned close to the arc-shaped part. Each swinging member is provided with a limiting part, which cooperates to clamp the optical fiber placed between the front opening and the arc-shaped part, and exposes the middle section of the optical fiber facing the arc-shaped part.

[0008] A swing drive device is provided in the mounting cavity. The swing drive device is used to drive the swing member to swing so that the limiting part bends the optical fiber toward the arc-shaped part or straightens the optical fiber horizontally toward the front opening.

[0009] In this design, the oscillating drive device drives the oscillating member to abut against the arc-shaped portion of the fiber when bending it. The included angle of the two oscillating members forms a recess facing the arc-shaped portion. This recess can closely engage with the arc-shaped portion, thereby bending the fiber clamped between the recess and the arc-shaped portion. Furthermore, the oscillating drive device drives the oscillating member to swing back towards the front opening. With the help of the limiting part clamping the fiber, the oscillating member can straighten the bent fiber during the swinging process. This fiber clamping device has the functions of both bending and straightening the fiber, preventing the fiber being bent from being in a bent state for a long time, so that the fiber can maintain good transmission performance.

[0010] In some embodiments, the first end of the swing member is rotatably disposed on the base or cover and positioned close to the apex of the arc-shaped portion. The second end of the swing member extends toward both sides of the apex of the arc-shaped portion. The limiting portion is close to the second end of the swing member. The limiting portions are disposed apart to form a notch between the limiting portions toward the arc-shaped portion. The swing driving device drives the swing member to swing relative to the arc-shaped portion with its own first end as the axis.

[0011] In this design, the two oscillating members swing toward the arc-shaped member with their first ends as the axis, forming a recess that matches the arc-shaped part. Since the first end of the oscillating member is close to the arc apex of the arc-shaped part, it is convenient to clamp the optical fiber between the first end of the oscillating member and the arc apex of the arc-shaped part. The middle section of the optical fiber can be exposed toward the arc-shaped part through the notch between the limiting parts. Thus, the arc apex of the arc-shaped part can abut against the optical fiber to provide support force and bending force.

[0012] In some embodiments, the swing drive device includes a pair of transmission rods that correspond one-to-one with the swing member and a telescopic drive member with a telescopic shaft. The telescopic drive member is disposed in the mounting cavity. The first end of each transmission rod is hinged to the telescopic shaft, and the second end of each transmission rod extends out of the mounting cavity from the front opening and is hinged to the corresponding swing member.

[0013] The telescopic shaft reciprocates back and forth relative to the front opening and drives the swinging member through the transmission rod, so that the limiting part swings closer to or away from the arc-shaped part.

[0014] In this scheme, the two ends of the transmission rod are respectively hinged to the swinging component and the telescopic shaft. Thus, based on the reciprocating motion of one telescopic shaft, the two swinging components can be simultaneously driven to swing and move toward the arc-shaped part, thereby forming a recess that matches the arc-shaped part. The swinging drive device of this scheme has a simple structure and can realize synchronous drive of the two swinging components, thereby improving the stability of clamping and bending optical fibers.

[0015] In some embodiments, a connecting seat is provided between the telescopic shaft and the transmission rod. The connecting seat has a fastening part and two first hinge parts. The fastening part is fixedly connected to the telescopic shaft, and the two first hinge parts are movably connected to the first end of the corresponding transmission rod.

[0016] This solution can synchronously drive two transmission rods through a telescopic shaft to achieve the purpose of swing control of two swinging components.

[0017] In some embodiments, each of the swing members 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.

[0018] The second hinge in this design does not increase the height of the swing component, thus avoiding obstruction of the transmission rod in the height space during the movement of the swing component.

[0019] In some embodiments, the limiting portion includes an upward-facing groove located on the side of the swing member near the arcuate portion.

[0020] The groove structure of this solution is simple and can stably limit the radial movement of the optical fiber, ensuring that the optical fiber bends and straightens back as the oscillating component swings.

[0021] In some embodiments, the arcuate portion is spaced apart from the oscillating member so that the arcuate portion abuts against the optical fiber placed within the notch.

[0022] This solution ensures that when the oscillating component swings toward the arc-shaped part, the optical fiber can be brought into contact with the arc-shaped part, and the apex of the arc-shaped part can provide support force and bending force for the optical fiber, improving bending or straightening efficiency and enhancing the limiting stability of the optical fiber.

[0023] In some embodiments, the first end of the swing member is provided with a gap, and the position of the arc apex of the arc-shaped portion corresponds to the gap between the first ends of the swing member.

[0024] In this design, when the optical fiber is bent, the optical fiber corresponding to the apex of the arc is pressed towards the gap position. The optical fiber at this position forms an arc shape similar to the shape of the apex, which can avoid the formation of a sharp angle at the apex of the bent optical fiber and reduce damage to the optical fiber.

[0025] In some embodiments, a controller is also included, which is disposed in the mounting cavity, and the telescopic drive is electrically connected to the controller.

[0026] In some embodiments, a detection element for the telescopic shaft is also included, the detection element being disposed in the mounting cavity and electrically connected to the controller, the detection element being configured to generate a sensing signal when the telescopic shaft reciprocates to a preset position.

[0027] In some embodiments, a fiber-feeding gap is formed between the cover and the fiber-blocking member, and the fiber-feeding gap has an upper opening;

[0028] The fiber clamp also includes a limiting member, which is slidably disposed on the base or cover to cover the upper opening or expose the upper opening. The limiting member is provided with a sliding operation part, which extends out of the cover from the mounting cavity.

[0029] In some embodiments, the upper part of the fiber-blocking member is provided with a light-shielding portion.

[0030] In some embodiments, the cover exposes controls for controlling the swing drive.

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows: the swing drive device drives the swing member to bend part of the optical fiber between the two limiting parts toward the arc-shaped part and abut against the arc-shaped part, and drives the swing member to swing back in the direction of the opening. With the limiting part clamping the optical fiber, the swing member can straighten the bent optical fiber. Thus, the fiber clamp has the functions of bending and straightening optical fiber, preventing the optical fiber being detected by bending from being in a bent state for a long time, so that the optical fiber can maintain good transmission performance.

Detailed Implementation

[0038] 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.

[0039] Example 1

[0040] like Figures 1-3 As shown, this embodiment provides a fiber clamp, including:

[0041] The housing includes a cover 100 and a base 200 connected to each other. The cover 100 and the base 200 enclose a mounting cavity. The cover 100 has a front opening 110 communicating with the mounting cavity. The base 200 includes a fiber-blocking member 210 extending forward relative to the front opening 110. The fiber-blocking member 210 has an arc-shaped portion 211 protruding toward the front opening 110. The front opening 110 and the arc-shaped portion 211 are spaced apart.

[0042] A pair of swing members 300 are movably mounted on the base 200 and close to the arc-shaped part 211. Both swing members 300 are provided with limiting parts 310 for placing optical fibers. The two limiting parts 310 cooperate to clamp the optical fiber placed between the front opening 110 and the arc-shaped part 211, and make the middle section of the optical fiber face the arc-shaped part 211.

[0043] A swing drive device is provided in the mounting cavity. The swing drive device is used to drive the swing member 300 to swing so that the limiting part 310 bends the optical fiber toward the arc-shaped part 211 or straightens the optical fiber horizontally toward the opening direction.

[0044] In use, the optical fiber is placed in the limiting part 310 of the swing member 300 through the space between the front opening 110 and the arc-shaped part 211. When the optical fiber is bent, the swing driving device drives the swing member 300 to bring the middle section of the optical fiber corresponding to the position of the arc-shaped part 211 towards the arc-shaped part 211. The two swing members 300 are set at an angle after swinging to form a recess facing the arc-shaped part 211. The recess can be close to the arc-shaped part 211 to bend the optical fiber sandwiched between the recess and the arc-shaped part 211. Then, the light signal leaked at the bending position of the optical fiber can be detected by the detection device based on the macro bending effect. After the test is completed, the swing drive device drives the swing member 300 to swing back towards the opening. With the help of the limiting part 310 to clamp the optical fiber, the swing member 300 can straighten the bent optical fiber during the swing process. Therefore, the fiber clamp of this invention can both bend and straighten the optical fiber. Compared with existing fiber clamps, the fiber clamp of this invention has the functions of both bending and straightening optical fibers, preventing the optical fiber being tested from being in a bent state for a long time, thus ensuring that the optical fiber can maintain good transmission performance. When no bending operation is performed, the two swing members 300 are at a horizontal angle. Figure 1 , 2 In some embodiments, in order to enhance the protective strength, the cover 100 is configured to cover the swing member 300 when in a horizontal angle state, and only the limiting part 310 extends out relative to the front end of the cover 100. Specifically, the limiting part 310 is positioned in the gap between the cover 100 and the arc-shaped part 211, so that the optical fiber can be inserted into the limiting part 310 through the gap between the cover 100 and the fiber blocking member 210.

[0045] In some other embodiments, the swing member 300 may also be movably disposed on the cover 100 and positioned close to the arc-shaped portion 211.

[0046] like Figures 2-3 As shown, in some embodiments, the first end of the swing member 300 is rotatably disposed on the base 200 or the cover 100 and positioned close to the apex of the arc-shaped portion 211. The second end of the swing member 300 extends toward both sides of the apex of the arc-shaped portion 211. The limiting portion 310 is close to the second end of the swing member 300, and the limiting portions 310 are disposed apart to form a notch 312 facing the arc-shaped portion between the limiting portions 310. The swing driving device drives the swing member 300 to swing relative to the arc-shaped portion 211 about its own first end as an axis. For specific implementation, refer to Figures 4-5Each of the swing members 300 has a through hole 330 at its first end, and the bottom surface of the fiber-blocking member 210 has two protruding shafts 213. The through holes 330 of the swing members 300 are fitted onto the corresponding protruding shafts 213, so that the swing members 300 can rotate and swing about their own first ends as axes. In this way, the two swing members 300 swing towards the arc-shaped member about their own first ends as axes to form a recess that matches the arc-shaped part 211. Since the first end of the swing member 300 is close to the arc apex of the arc-shaped part 211, it is convenient to clamp the optical fiber between the first end of the swing member 300 and the arc apex of the arc-shaped part 211. The middle section of the optical fiber can be exposed towards the arc-shaped part 211 through the notch 312 between the limiting parts 310. Thus, the arc apex of the arc-shaped part 211 can abut against the optical fiber to provide support and bending force. Preferably, the first end of the oscillating member 300 corresponds to the apex of the arc of the arc-shaped portion 211. Thus, the first ends of the two oscillating members 300 form a concave apex, facilitating alignment and engagement with the apex of the arc of the arc-shaped portion 211, enabling stable contact and bending of the optical fiber. It is understood that in some other embodiments, the first end of the oscillating member 300 may be provided with a convex shaft, and a hole for the convex shaft to rotate and engage may be provided on the bottom surface of the fiber-blocking member 210. Other configurations may also be used to ensure that the oscillating member 300 can rotate and oscillate around its own first end as an axis.

[0047] like Figures 4-5 As shown, in some embodiments, the swing drive device includes a telescopic drive member 400 with a telescopic shaft 410 and a pair of transmission rods 500 that cooperate with each swing member. The telescopic drive member 400 is disposed in the mounting cavity. The first ends of the two transmission rods 500 are hinged to the telescopic shaft 410 of the telescopic drive member 400, and the second ends of the two transmission rods 500 extend from the front opening 110 of the mounting cavity and are respectively hinged to the corresponding swing members 300. The telescopic shaft 410 reciprocates relative to the front opening 110 and drives the swing members 300 through the transmission rods 500. Thus, the limiting part 310 of the swing member 300 swings towards or away from the arc-shaped part 211. In specific applications, the reciprocating motion of one telescopic shaft 410 can simultaneously drive the two swing members 300 to swing and move towards the arc-shaped part 211, thereby forming a recess that cooperates with the arc-shaped part 211. This swing drive device has a simple structure and can realize synchronous driving of the two swing members 300, thereby improving the stability of clamping and bending optical fibers. In practice, to improve control precision, the telescopic drive component 400 can be a stepper motor.

[0048] Continue to refer to Figure 5In specific implementation, a connecting seat 600 is provided between the telescopic shaft 410 and the transmission rod 500. The connecting seat 600 has a fastening part 610 and two first hinge parts 620. The fastening part 610 is fixedly connected to the telescopic shaft 410, and the two first hinge parts 620 are respectively movably connected to the first end of the corresponding transmission rod 500. In practice, the fastening part 610 can be a bushing that matches the outer diameter of the telescopic shaft 410. The first hinge parts 620 are respectively provided on both sides of the fastening part 610. Specifically, in order to ensure smooth transmission, the first hinge part 620 can be a bearing boss. The first end of the transmission rod 500 is provided with a connecting hole 510 for fitting the bearing boss. Thus, the first end of the transmission rod 500 can be stably hinged to the telescopic shaft 410. In this way, the two transmission rods 500 can be driven synchronously through one telescopic shaft 410 to achieve the purpose of swing control of the two swinging parts 300. It is easy to understand that in some other embodiments, the first hinge portion 620 may adopt a connecting hole 510, and the first end of the transmission rod 500 may be provided with a bearing boss that mates with the bearing in the connecting hole 510. Alternatively, other hinge forms may be used to ensure that the transmission component can swing about its own first end as an axis.

[0049] refer to Figure 4 , 5 In some embodiments, each of the swing member 300 has a second hinge portion 320 on the side near the transmission rod 500. The second hinge portion 320 is movably connected to the second end of the corresponding transmission rod 500. Specifically, the second hinge portion 320 can be a bearing hole connected to the swing member 300, and the second end of the transmission rod 500 has a shaft 520 that mates with the bearing in the bearing hole. Thus, the two transmission rods 500 can adjust their spacing appropriately as the swing member 300 swings back and forth, allowing the transmission system composed of the telescopic drive member 400, transmission rod 500, and swing member 300 to operate smoothly and stably. Furthermore, since the second hinge portion 320 is located on the side of the swing member 300, it does not increase the height of the swing member 300, thus preventing the transmission rod 500 from being obstructed by other structures in the height space during the movement of the swing member 300.

[0050] In other embodiments, the swing drive device can also be implemented by a combination of a rotary drive and a transmission gear or a transmission belt. The rotary drive rotates to drive the transmission gear and drives the first ends of the two swing members 300 to rotate and swing, thereby driving the swing members 300 to bend the optical fiber toward the arc-shaped part 211 or to straighten the optical fiber horizontally toward the front opening 110.

[0051] Alternatively, in other embodiments, the oscillation drive device can be a manually operable reciprocating drive mechanism. Specifically, for example, it can employ a movable member that can slide back and forth on the base 200 or the cover 100. The movable member is movably connected to the oscillating member 300 via a component similar to a transmission rod 500. Thus, by pushing the movable member, the oscillating member 300 can bend the optical fiber towards the arc-shaped portion 211, and by pushing the movable member back, the optical fiber can be straightened horizontally. Furthermore, a reset spring can be used in conjunction with the movable member, so that when the operator releases the restriction on the movable member, the movable member can return to its original position with the help of the reset spring, thereby automatically straightening the optical fiber horizontally.

[0052] refer to Figure 4 In some embodiments, the limiting part 310 includes an upward-facing groove located on the side of the swing member 300 near the arc-shaped part 211. It is understood that the groove structure is simple and can stably limit the radial movement of the optical fiber, ensuring that the optical fiber bends and straightens as the swing member 300 swings. In other embodiments, the groove can also be located on the top of the swing member 300. Specifically, to improve limiting stability, the width of the groove is approximately equal to the outer diameter of the optical fiber under test. Furthermore, an anti-slip structure can be added inside the groove, such as several protruding ridges 311 on the inner wall of the groove, to increase the friction between the groove and the surface of the optical fiber.

[0053] refer to Figures 4-5 In some embodiments, the arc-shaped portion 211 is spaced apart from the oscillating member 300 so that the arc-shaped portion 211 abuts against the optical fiber placed in the notch 312. In specific implementations, the limiting portions 310 are respectively provided on the outer section along the length direction of the corresponding oscillating member 300. Preferably, the limiting portions 310 are respectively provided on the second end of the corresponding oscillating member 300. Thus, when the optical fiber is limited on the two grooves, the optical fiber located between the two limiting portions 310 can abut against the arc-shaped portion 211, and the arc apex of the arc portion 211 can provide support force and bending force for the optical fiber, improve bending or straightening efficiency, and enhance the limiting stability of the optical fiber.

[0054] refer to Figure 2 , 4 The first ends of the two swinging members 300 are separated by a gap. The position of the arc apex of the arc-shaped part 211 corresponds to the gap between the first ends of the swinging members 300. When bending the optical fiber, the optical fiber corresponding to the arc apex of the arc-shaped part 211 is pressed towards the gap position. The optical fiber at this position forms an arc shape similar to the arc apex shape, which can avoid the formation of a sharp angle at the vertex position of the bent optical fiber and reduce damage to the optical fiber.

[0055] refer to Figure 2For ease of operation, a controller 700 is also included. The controller 700 is located in the mounting cavity, and the telescopic drive 400 is electrically connected to the controller 700. By operating the controller 700, the operator can bend or straighten the fiber optic cable using the fiber clamp. In some embodiments, the cover 100 exposes a control component 710 for controlling the swing drive device. Specifically, the control component 710 can be implemented in the form of buttons, and the controller 700 can be a control board.

[0056] Referring to the figure, a detection element 800 for the telescopic shaft is also included. The detection element 800 is disposed in the mounting cavity and electrically connected to the controller 700. The detection element 800 is configured to generate a sensing signal when the telescopic shaft reciprocates to a preset position. In a specific implementation, the connecting seat 600 has a downward-facing sensing protrusion 630, and the detection element 800 is located on the path of the forward and backward movement of the sensing protrusion 630. Specifically, when the telescopic drive 400 drives the two swinging members 300 to swing back to a horizontal angle, the detection element 800 detects the sensing protrusion 630, generates a sensing signal, and sends a command to the controller 700 to stop the telescopic drive 400. By setting the sensing element, the precise operation of the telescopic drive 400 can be ensured, and damage to the optical fiber caused by excessive swinging of the swing arm can be prevented.

[0057] refer to Figure 1 , 2The front end of the cover 100 protrudes forward and forms a fiber feeding gap 120 with the fiber blocking member. The fiber feeding gap 120 has an upper opening. The fiber clamp also includes a limiting member 900. The limiting member 900 can slide back and forth on the base 200 or the cover 100. The limiting member 900 is used to cover the upper opening or expose the upper opening. The limiting member 900 is provided with a sliding operation part 910. The sliding operation part 910 extends out of the cover 100 from the mounting cavity. In specific implementation, the cover 100 has an opening 130, through which the sliding operation part 910 extends. The limiting member 900 has several elongated holes 920. The inner surface of the base 200 and / or the cover 100 has protrusions 220 for passing through the elongated holes 920. Thus, the limiting member 900 can slide back and forth in the remaining space after the protrusions 220 engage with the elongated holes 920. The front of the limiting member 900 has a blocking part 930. When the limiting member slides back and forth relative to the base 200, the blocking part 930 moves back and forth relative to the front opening 110. The upper opening of the fiber placement gap 120 is covered or exposed. When the limiting member 900 slides forward so that the blocking part 930 covers the upper opening, the blocking part 930 can limit the vertical movement of the optical fiber placed in the limiting part 310. Thus, the limiting part 310 and the limiting member 900 together form an optical fiber limiting space, preventing the optical fiber from falling off during the bending or straightening of the optical fiber, and also providing a light-shielding function. When the limiting member 900 slides backward so that the blocking part 930 retracts from the upper opening, the optical fiber can be inserted into the limiting part 310 through the upper opening. Preferably, a return spring is also provided between the limiting member 900 and the base 200 or the cover 100. In this way, when the sliding operation part 910 is operated, the upper opening of the fiber feeding gap 120 is exposed. When the sliding operation part 910 is released, the elastic force of the return spring will reset the limiting member 900 to cover the upper opening of the fiber feeding gap 120.

[0058] refer to Figures 1-3 The upper part of the fiber blocking member 210 is provided with a light-shielding part 212. In a specific implementation, the light-shielding part 212 is a light-shielding member that protrudes outward from the upper surface of the arc-shaped part 211, so as to prevent ambient light from shining on the optical fiber when the optical fiber is bent to the arc-shaped part 211, thereby ensuring the accuracy of the optical signal results detected by the detection device based on the macro-bending effect.

[0059] refer to Figures 1-5 The working principle of this utility model is as follows:

[0060] By operating the sliding operation part 910 backward, the blocking part 930 retracts into the mounting cavity. The optical fiber to be tested is inserted into the limiting part 310 located in front of the two swinging members 300 through the upper opening of the fiber release gap 120. When the sliding operation part 910 is released, the blocking part 930 automatically rebounds and covers the upper opening of the fiber release gap 120 to block and limit the optical fiber. By pressing the control member 710 exposed on the surface of the cover 100, the telescopic drive member 400 extends forward and moves forward. The two transmission rods 500 drive the two swinging members 300 to swing toward the arc-shaped part 211. As a result, the optical fiber at the notch 312 abuts against the arc-shaped part 211 and bends under the continuous pressure of the two swinging arms. After the fiber optic cable is inspected, the telescopic drive 400 retracts backward, and through the two transmission rods 500, the two swinging parts 300 swing back to a horizontal angle, so that the fiber optic cable limited in the limiting part 310 straightens horizontally with the swinging parts 300.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
