Description

Technical Field

[0001] This invention relates to the field of optical cable laying and maintenance, and specifically to an optical cable stripping clamping device and method. Background Technology

[0002] Optical fiber cables are communication cable assemblies that use one or more optical fibers encased in a sheath (optical cable outer jacket) as the transmission medium and can be used individually or in groups. Optical fiber cables are typically buried underground, and the outer sheath serves to isolate the optical fibers and prevent corrosion. With the rapid development of optical communication networks, their coverage is expanding, finding applications in cities, enterprises, transportation sectors such as high-speed rail, and energy and chemical industries, including national pipeline networks. The requirements for optical fiber cable construction (splitting processes and procedures) are also constantly increasing. To cope with this rapid development, traditional processes and procedures are no longer sufficient. As communication improves the speed of information exchange, the timeliness of optical fiber cable repair and restoration is also paramount.

[0003] In the construction, renovation, maintenance, and emergency repair of existing optical cables, the removal of the outer sheath is primarily done manually within limited space and time. Due to the small diameter and compact nature of optical cables, the stripping length is limited each time. Furthermore, factors such as slipperiness during operation can make directly using hands to grip and pull the outer sheath not only labor-intensive, inefficient, and physically demanding, but also prone to damaging the cable if improper force is applied. Additionally, existing tools are difficult to operate, have limited application scenarios, and require extensive manual experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is how to easily clamp and remove the outer sheath of the optical cable.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A fiber optic cable stripping clamping device includes a base assembly, a snap fastener assembly, and a wire biting device. The wire biting device includes a first wire biting component and a second wire biting component. The snap fastener assembly is hinged to the base assembly. The first wire biting component and the second wire biting component are detachably connected to the snap fastener assembly and the base assembly, respectively. The first wire biting component and the second wire biting component are correspondingly arranged and each has a clamping arc surface for clamping the fiber optic cable.

[0006] The beneficial effects of this invention are: by using the clamping arc surfaces of the first and second clamping components to hold the optical cable on the outside, and by pulling the optical cable stripping clamping device with the hand-held base assembly and snap-fit ​​assembly, the optical cable sheath can be removed quickly and effortlessly, improving work efficiency. Clamping devices with different clamping arc surface sizes can be replaced to adapt to the removal of optical cable sheaths of different sizes. This device has a simple structure, stable performance, saves time and effort, and is easy to carry. The optical cable stripping clamping device and its usage method are applicable to all optical cable construction situations, and even beginners can quickly learn to operate it.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the base assembly includes a first hand-held part, a base, and a second hand-held part that are fixedly connected in sequence. One end or the middle of the snap fastener is hinged to one end of the base, and the second wire-biting member is detachably connected to the base.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the base for installing the second wire-biting component is set in the middle of the base assembly. When in use, the operator can grasp the first hand-held part and the second hand-held part with both hands respectively, and apply force from both sides of the optical cable at the same time, which is convenient for removing the outer sheath of the optical cable. The operation is simple, the stripping length is long, and the speed is fast.

[0010] Furthermore, the snap fastener assembly includes a snap fastener and a hand-held pressure bar. One end or the middle of the snap fastener is hinged to one end of the base, and the other end is fixedly connected to the hand-held pressure bar. The first wire-biting member and the middle or one end of the snap fastener are detachably connected.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: When the hand-held pressure lever is rotated close to the second hand-held part, the clamp and the base move closer together, and the first and second wire-biting components clamp the optical cable sheath. When pulling out the optical cable sheath, the operator holds the first hand-held part with one hand and the hand-held pressure lever and the second hand-held part with the other hand, applying force with both hands simultaneously, making it easier to remove the optical cable sheath. Moreover, the application of force with the other hand also presses the hand-held pressure lever and the second hand-held part tighter, further increasing the clamping force on the optical cable and increasing the reliability of the clamping.

[0012] Furthermore, the first hand-held part, the second hand-held part, and the hand-held pressure rod are fitted with anti-slip rubber sleeves.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip rubber sleeve can effectively prevent slippage when the first hand-held part, the second hand-held part, and the hand-held pressure bar are operated.

[0014] Furthermore, the axial lengths of the first and second wire-biting components along the clamping arc surface are both greater than the axial lengths of the base assembly or the snap fastener assembly along the clamping arc surface.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the axial length of the first and second biting components is large, the contact area between the biting device and the optical cable is larger when the optical cable is peeled, the friction force on the outer sheath of the optical cable is greater, and the outer sheath of the optical cable can be removed more effectively.

[0016] Furthermore, the cross-sectional shape of both the first biting member and the second biting member is a fan-shaped ring.

[0017] Furthermore, the central angle of each of the fan-shaped rings is less than 180°.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the central angle of the fan ring is less than 180°, which avoids interference between the first and second biting components when they are close to each other; when biting a small diameter optical cable, if the central angle is 180°, the end faces of the two components that are close to each other will come into contact with each other, affecting the biting force of the optical cable. With this solution, the central angle is less than 180°, which can also effectively clamp the small diameter optical cable.

[0019] Furthermore, the clamping arc surface is provided with friction textures or friction protrusions.

[0020] The beneficial effect of adopting the above-mentioned further solution is that friction textures or friction protrusions are set on the clamping arc surface to increase the friction with the outer sheath of the optical cable.

[0021] The present invention also provides a method for stripping optical cables, which is implemented using two of the aforementioned optical cable stripping clamping devices, and includes the following steps:

[0022] Cut the outer sheath of the optical cable circumferentially from the middle of the optical cable. The two wire-biting devices of the optical cable stripping clamping device clamp the outer sheath of the optical cable at both ends of the cut. Hold the base assembly and the snap fastener assembly of the optical cable stripping clamping device and pull the two optical cable stripping clamping devices in opposite directions along the optical cable axis until the outer sheath of one end of the optical cable is separated from the optical fiber.

[0023] The beneficial effects are: by using the clamping arc surfaces of the first and second wire-biting components of the two optical cable stripping clamping devices to clamp the outer sides of both ends of the optical cable, and by pulling the two optical cable stripping clamping devices in the opposite direction by holding the base assembly and the snap fastener assembly, the outer sheath of the optical cable can be removed quickly and effortlessly, improving work efficiency and making the operation simple.

[0024] Furthermore, one of the optical cable stripping clamping devices has friction textures or friction protrusions on its clamping arc surface, while the other optical cable stripping clamping device has a smooth arc surface.

[0025] The beneficial effects of adopting the above-mentioned further solutions are: friction textures or friction protrusions can increase the friction with the optical cable sheath, mainly used on the optical cable sheath that needs to be removed, and another optical cable stripping clamping device is used on the optical cable sheath that needs to be retained, which can play a certain role in fixing and protect the optical cable sheath from damage.

[0036] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0037] like Figures 1-7As shown, the present invention provides an optical cable stripping clamping device, including a base assembly, a snap fastener assembly, and a wire biting device 4. The wire biting device 4 includes a first wire biting member 401 and a second wire biting member 402. The snap fastener assembly is hinged to the base assembly. The first wire biting member 401 and the second wire biting member 402 are detachably connected to the snap fastener assembly and the base assembly, respectively. The first wire biting member 401 and the second wire biting member 402 are correspondingly arranged and each has a clamping arc surface for clamping the optical cable.

[0038] The optical cable sheath is clamped to the outside of the optical cable using the clamping arc surfaces of the first and second clamping components 401 and 402. By pulling the base assembly and snap-fit ​​assembly, the optical cable sheath can be removed quickly and effortlessly, improving work efficiency. Clamping components 4 with different clamping arc surface sizes can be used to accommodate the removal of optical cable sheaths 100 of different sizes. This device has a simple structure, stable performance, saves time and effort, and is easy to carry. The optical cable sheath removal clamp and its usage method are applicable to all optical cable construction situations, and even beginners can quickly learn to operate it.

[0039] Specifically, the two clamping arc surfaces of the first wire-biting member 401 and the second wire-biting member 402 have the same radius. As the base assembly and the snap fastener assembly rotate relative to each other, the two clamping arc surfaces of the first wire-biting member 401 and the second wire-biting member 402 can rotate to be coaxial and form a complete circle or a circle with a partial gap.

[0040] In use, the base assembly and the snap fastener are rotated relative to each other, so that the first wire-biting member 401 and the second wire-biting member 402 come closer to each other and clamp the optical cable, or the first wire-biting member 401 and the second wire-biting member 402 are moved away from each other and the optical cable is released.

[0041] Based on the above scheme, the base assembly includes a first hand-held part 1, a base 6 and a second hand-held part 2 that are fixedly connected in sequence. One end or the middle of the snap fastener is hinged to one end of the base 6, and the second wire-biting member 402 is detachably connected to the base 6.

[0042] The base 6 for installing the second wire-biting component 402 is located in the middle of the base assembly. When in use, the operator can grasp the first hand-held part 1 and the second hand-held part 2 with both hands respectively, and apply force from both sides of the optical cable at the same time, which is convenient for removing the outer sheath 100 of the optical cable. The operation is simple, the stripping length is long, and the speed is fast.

[0043] Alternatively, the first hand-held part 1, the base 6, and the second hand-held part 2 can also be detachably connected in sequence, which facilitates disassembly and storage and saves space.

[0044] like Figure 1The image shows one end of the snap-fit ​​connector hinged to one end of the base 6. This structure is relatively simple and easy to carry. When the middle part of the snap-fit ​​connector is hinged to one end of the base 6, the optical cable stripping clamping device is X-shaped, and one hand and the snap-fit ​​connector can be held simultaneously on both sides of the optical cable, which facilitates applying clamping force to the optical cable.

[0045] Based on any of the above solutions, the snap fastener assembly includes a snap fastener 5 and a hand-held pressure bar 3. One end or the middle of the snap fastener 5 is hinged to one end of the base 6, and the other end is fixedly connected to the hand-held pressure bar 3. The first wire-biting member 401 and the middle or one end of the snap fastener 5 are detachably connected.

[0046] When the hand-held pressure lever 3 is rotated close to the second hand-held part 2, the clamp 5 and the base 6 move closer together, and the first wire-biting component 401 and the second wire-biting component 402 clamp the optical cable sheath 100. When pulling the optical cable sheath 100, the operator holds the first hand-held part 1 with one hand and the hand-held pressure lever 3 and the second hand-held part 2 with the other hand, applying force with both hands simultaneously, making it easier to remove the optical cable sheath 100. Moreover, the application of force with the other hand also presses the hand-held pressure lever 3 and the second hand-held part 2 more tightly, further increasing the clamping force on the optical cable and increasing the reliability of the clamping.

[0047] In this embodiment, the specific shapes of the base 6 and the buckle 5 are not limited, and they can be any shape.

[0048] Alternatively, the snap fastener 5 and the hand lever 3 can also be detachable, making them easy to disassemble and store, thus saving space.

[0049] In one specific example, both the base 6 and the snap fastener 5 are semi-circular ring structures. When they are closed, they form a circular cavity inside, which is used to accommodate the wire-gripping device 4. The first hand-held part 1, the second hand-held part 2, and the hand-held pressure rod 3 are all strip-shaped rods or other types of handles. The first hand-held part 1, the second hand-held part 2, and the hand-held pressure rod 3 increase the lever arm length. By applying force to the hand-held pressure rod 3 and the second hand-held part 2, the snap fastener 5 can move easily and efficiently. Figure 1 As shown, when the second hand-held part 2 and the hand-held pressure rod 3 are rotated to be parallel to each other, the extension line of the first hand-held part 1 is located between the second hand-held part 2 and the hand-held pressure rod 3. In this way, the forces on both sides of the optical cable are balanced, and the outer sheath 100 of the optical cable can be removed stably.

[0050] Specifically, the first biting component 401 and the second biting component 402 can be configured as multiple sets of standard biting devices. The clamping arc surfaces of the multiple sets of standard biting devices are designed with arc surfaces of different radii, so that different standard biting devices can be adjusted and replaced according to the diameter of the optical cable being worked on. The outer walls of the first biting component 401 and the second biting component 402 are detachably connected to the snap fastener 5 and the base 6, respectively. When biting the optical cable, the force on the first biting component 401 and the second biting component 402 comes from the radial clamping force formed when the snap fastener 5 and the base 6 are closed.

[0051] In one specific example, the first biting member 401 and the second biting member 402 are fastened to the snap fastener 5 and the base 6 respectively by bolts. Specifically, through holes or threaded holes are provided on the snap fastener 5 and the base 6, and threaded blind holes or threaded through holes are provided on both the first biting member 401 and the second biting member 402. A bolt passes through the through hole on the snap fastener 5 and is threadedly connected to the first biting member 401, and another bolt passes through the through hole on the base 6 and is threadedly connected to the second biting member 402. This allows the bolts to fasten the first biting member 401 to the snap fastener 5 and the second biting member 402 to the base 6. By loosening or tightening the bolts that fix the first biting member 401 and the second biting member 402, the distance between the first biting member 401 and the second biting member 402 when they are closed can be adjusted. Thus, the distance between the clamping arc surfaces of the first biting member 401 and the second biting member 402 can be adjusted, which can be applied to the clamping of optical cables of different diameters. Based on this suggestion, the connection method can also be designed as a slot connection or other detachable connection method, so as to facilitate the replacement of different wire bite devices 4.

[0052] In one specific example, the base 6 and the snap fastener 5 are connected by a hinge; the base 6 and the snap fastener 5 are respectively provided with a first through hole 601 and a second through hole 501 for the hinge pin to pass through; when the snap fastener 5 is subjected to external force, it moves relative to the base 6 with the hinge axis as the axis.

[0053] Based on any of the above solutions, the first hand-held part 1, the second hand-held part 2, and the hand-held pressure rod 3 are fitted with anti-slip rubber sleeves.

[0054] When operating with the first hand grip 1, the second hand grip 2 and the hand grip lever 3, the anti-slip rubber sleeve can effectively prevent slipping.

[0055] Based on any of the above solutions, the axial lengths of the first wire-biting member 401 and the second wire-biting member 402 along the clamping arc surface are both greater than the axial lengths of the base assembly or the snap fastener assembly along the clamping arc surface.

[0056] The first biting member 401 and the second biting member 402 have large axial lengths. When the optical cable is peeled, the contact area between the biting device 4 and the optical cable is larger, and the friction force on the optical cable sheath 100 is greater, which can remove the optical cable sheath 100 more effectively.

[0057] The axial length mentioned here refers to the axial direction of the optical cable when the device clamps the optical cable.

[0058] Based on any of the above schemes, the cross-sectional shape of the first biting member 401 and the second biting member 402 is a fan-shaped ring.

[0059] Specifically, the arc-shaped surfaces near the center of both the first biting member 401 and the second biting member 402 are clamping arc surfaces. The empty areas near the center of the first biting member 401 and the second biting member 402 are used to accommodate the optical cable.

[0060] Based on any of the above schemes, the central angle of the fan-shaped ring is less than 180°.

[0061] The central angle of the fan-shaped ring is less than 180° to avoid interference between the first and second biting components when they are close together. When biting a small diameter optical cable, if the central angle is 180°, the end faces of the two components will come into contact with each other, affecting the biting force. With this solution, the central angle is less than 180°, which can effectively clamp the optical cable even if the diameter is small.

[0062] Based on any of the above schemes, such as Figure 7 As shown, the clamping arc surface is provided with friction textures or friction protrusions.

[0063] Friction textures or friction protrusions are provided on the clamping arc surface to increase the friction with the outer sheath 100 of the optical cable.

[0064] Specifically, optical cables are generally in complex polluted environments such as oil, water, mud, and dust. Foreign objects on the outer layer can affect the clamping force. This invention sets protrusions or textures on the clamping arc surface that contacts the optical cable, which can effectively increase the clamping force of the wire biting device 4 on the optical cable when the wire biting device 4 is subjected to external force, thereby improving the efficiency of removing the outer sheath 100 of the optical cable.

[0065] In addition, the first hand-held part 1, the hand-held pressure rod 3, and the second hand-held part 2 can all have a connection structure that can be directly connected to other mechanical components. For example, by means of bolt fastening, slot connection or sleeve connection, when encountering the need for large-scale optical cable operation, the first hand-held part 1, the hand-held pressure rod 3 and the second hand-held part 2 can be connected to the power component (such as motor or cylinder), and the optical cable outer sheath 100 can be automatically removed with the help of the power component to increase the force.

[0066] The optical cable stripping clamping device of the present invention is used as follows: The first handheld part 1 and the second handheld part 2 are held manually or by other means. A force is applied to the handheld pressure rod 3 near the second handheld part 2, causing the pressure buckle 5 to rotate around the hinge point between the pressure buckle 5 and the base 6. At this time, the optical cable is inserted into the central angle of the biting device 4. The first biting member 401 and the second biting member 402 are subjected to a downward force from the pressure buckle 5 and an upward force from the base 6, thereby forming a clamping force on the optical cable. Then, the clamping device is dragged away from the main optical cable end. The friction of the first biting member 401 and the second biting member 402 against the optical cable sheath 100 removes the optical cable sheath 100.

[0067] like Figures 1-8 As shown, the present invention also provides a method for stripping optical cables, which is implemented using two of the aforementioned optical cable stripping clamping devices, and includes the following steps:

[0068] Cut the outer sheath 100 of the optical cable circumferentially from the middle of the optical cable. The two wire-biting devices 4 of the optical cable stripping clamping device respectively clamp the outer sheath 100 of the optical cable at both ends of the cut. Hold the base assembly and the snap fastener assembly of the optical cable stripping clamping device and pull the two optical cable stripping clamping devices in opposite directions along the optical cable axis until the outer sheath 100 of the optical cable at one end of the optical cable is separated from the optical fiber 200.

[0069] The first wire-biting component 401 and the second wire-biting component 402 of the two optical cable stripping clamps are clamped on the outer sides of both ends of the optical cable. By holding the base assembly and the snap fastener assembly and pulling the two optical cable stripping clamps in the opposite direction, the outer sheath of the optical cable can be removed quickly and effortlessly, improving work efficiency and making the operation simple.

[0070] Based on the above scheme, one of the optical cable stripping clamping devices has friction textures or friction protrusions on its clamping arc surface, while the other optical cable stripping clamping device has a smooth arc surface.

[0071] Friction textures or friction protrusions can increase the friction with the optical cable sheath 100 and are mainly used on the optical cable sheath 100 that needs to be removed. Another optical cable stripping clamp is used on the optical cable sheath 100 that needs to be retained. It can play a certain role in fixing and protect the optical cable sheath 100 from damage.

[0072] Specifically, such as Figure 8 As shown, the fiber optic cable sheath 100 that needs to be removed is located at its lower end, and the end of the fiber optic cable that needs to retain the fiber optic cable sheath 100 is located at its upper end (called the main fiber optic cable end). Usually, the main fiber optic cable end is relatively long, and the figure is only a schematic diagram.

[0073] The specific method for stripping the optical cable is as follows: The outer sheath 100 of the optical cable is cut circumferentially from the middle of the cable, but the internal optical fibers 200 are not cut. One of the optical cable stripping clamping devices, with its biting device 4, clamps the outer sheath 100 at the main cable end. The biting device 4 has friction grooves or friction protrusions on its clamping arc surface. The other optical cable stripping clamping device, with its biting device 4, clamps the outer sheath 100 at the lower end of the optical cable. Holding both optical cable stripping clamping devices, the two devices are pulled in opposite directions along the optical cable axis (e.g., ...). Figure 8 (As shown by the arrow) until the outer sheath 100 of the optical cable at the lower end of the optical cable separates from the optical fiber 200.
