Description

Technical Field

[0001] This invention relates to the technical field of phase-wire composite optical cable splicing, and in particular to a phase-wire composite optical cable protection splice and its installation method. Background Technology

[0002] Fiber optic composite overhead phase line is a new type of optoelectronic composite cable that integrates fiber optic units into power phase lines. It can simultaneously realize high-voltage power transmission and optical signal communication functions. With its advantages of compact structure, high resource utilization, and no need to lay separate communication lines, it is widely used in power engineering scenarios such as high-voltage power grids, smart grids, and distribution communication networks. It is the core transmission carrier for power Internet of Things, intelligent grid dispatching and operation and maintenance. In the construction, laying, line maintenance, and cable splicing of phase line composite optical cables, the splicing, sealing protection, and insulation isolation of cable ends are key links to ensure the long-term stable operation of the line, which directly determines the reliability of power supply and the quality of fiber optic communication transmission.

[0003] Currently, most existing phase-line composite optical cable splicing constructions use traditional splice boxes, which have revealed many technical defects in actual high-voltage operating conditions and complex outdoor environments.

[0004] For example, in the existing technology announcement number CN210572920U, the splicing device of the high-voltage power grid phase line composite optical cable has an insulating support on the base, a fiber optic coil cavity installed on the insulating support, the fiber optic coil cavity has a cavity cover and a fiber optic coil is placed inside it, and the fiber optic coil cavity and cavity cover are made of non-metallic insulating material.

[0005] The following defects have been found in the use of existing devices: Traditional integrated connectors are integrally sealed structures. Once a problem occurs in the line, the entire connector needs to be disassembled. This not only damages the overall sealing and protection system, but also makes maintenance work cumbersome, time-consuming and labor-intensive, with extremely low operation and maintenance efficiency, and poor operation economy and practicality. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a phase-line composite optical cable protection connector and its installation method that reduces mutual interference between optical fiber lines and power lines during individual maintenance, improves maintenance efficiency, and simultaneously reduces signal interference from power lines to optical fiber lines by setting up an isolation cavity, thereby improving the operational stability of the optical cable.

[0007] The present invention provides a phase-line composite optical cable protection connector, comprising a connection positioning component, an elastic support component, a clamping component, a housing, a partition, a first cover, a second cover, a hinge, a first through hole, and a second through hole. An opening is provided at the top of the enclosure, and two sets of partitions are placed inside the enclosure, which divide the enclosure into three chambers from left to right: an optical fiber docking chamber, an isolation chamber, and a power docking chamber. The first cover is installed at the top of the isolation chamber; Two sets of second covers are rotatably installed on both sides of the first cover via hinges, and the two sets of second covers are respectively installed on the top of the optical fiber docking cavity and the power docking cavity. The first cover, the second cover and the hinges are respectively fixedly connected to the housing by screws. Two sets of first through holes are respectively located on both sides of the box and communicate with the isolation cavity; Each set of partitions is provided with two sets of second through holes; The connection and positioning component is located inside the enclosure and is used to fix the positions of the fiber optic cable connection and the power line connection. The elastic support assembly is installed inside the housing and is used to provide elastic support and fixation for the phase-wire composite optical cable. The clamping assembly is located inside the housing and is used to clamp and fix the ends of the phase-wire composite optical cables. The ends of the two phase-wire composite optical cables to be spliced ​​are stripped, sequentially removing the outer sheath and phase conductor layer to expose the optical fiber and power line. Then, the two phase-wire composite optical cables are inserted into the isolation cavity through two sets of first through holes, and the two optical fibers are inserted into the optical fiber splicing cavity through two sets of second through holes. The two power lines are inserted into the power splicing cavity through the other two sets of second through holes. The two optical fibers and two power lines are then spliced. After splicing, the connection is established. The positioning components fix the connection positions of the fiber optic cable and the power cable respectively. Then, the first cover, the second cover, and the hinge cover are installed on the top of the box and fixed with screws, so that the three chambers of fiber optic cable connection, isolation chamber, and power cable connection are sealed individually. When it is necessary to inspect and maintain the connection position of the fiber optic cable or the power cable separately, only one chamber needs to be opened, which reduces mutual interference when the fiber optic cable and the power cable are maintained separately and improves the efficiency of inspection and maintenance. At the same time, the isolation chamber reduces the signal interference of the power cable to the fiber optic cable and improves the stability of the optical cable operation.

[0008] Preferably, the connecting positioning assembly includes a base, a support platform, a protective sleeve, a pressure plate, an internal thread seat, a bolt, a first spring, a first telescopic rod, and a second spring; Both sets of bases are installed on the inner side wall of the enclosure, and the two sets of bases are respectively located inside the fiber connection cavity and the power connection cavity; The two sets of support platforms are slidably installed on the two sets of bases, one above the other. Two sets of protective sleeves are placed on top of the two sets of support platforms respectively; Two sets of pressure plates are placed on top of the two sets of protective sleeves respectively; Multiple sets of internal thread seats are respectively set on the outer side wall of the two sets of bases, and multiple sets of bolts pass through the two sets of pressure plate bolts and are installed on the multiple sets of internal thread seats; Multiple sets of first springs are respectively fitted onto multiple sets of bolts; Multiple sets of first telescopic rods are installed between the box body and the support platform; Multiple sets of second springs are respectively fitted onto multiple sets of first telescopic rods; two sets of protective sleeves are respectively fitted onto the outside of the fiber optic cable connection position and the power line connection position. The two sets of protective sleeves are placed on the top of two sets of support platforms, and then two sets of pressure plates are pressed onto the two sets of protective sleeves. Subsequently, the two sets of pressure plates are pressed and fixed by the installation and cooperation of multiple sets of bolts and multiple sets of internal thread seats. Thus, the two sets of pressure plates and the two sets of support platforms work together to fix the position of the two sets of protective sleeves, improving the positioning effect of the fiber optic cable connection position and the power line connection position. The multiple sets of first telescopic rods and multiple sets of second springs provide elastic support to the support platforms, improving the floating support effect of the support platforms on the protective sleeves and avoiding damage to the connection position caused by the rigid pressing of the pressure plates on the protective sleeves. The multiple sets of first springs provide elastic support to the bottom of the pressure plates, which facilitates the increase of the installation friction between the bolts and the internal thread seats. This improves the installation stability of the bolts without requiring the bolts to apply a large pressure to the pressure plates, further avoiding squeezing damage to the connection position inside the protective sleeves.

[0009] Preferably, the elastic support assembly includes a first guide rail, a first slider, a second telescopic rod, a third spring, a first guide member, and a second guide member; Both sets of first guide rails are installed on the inner side wall of the box inside the isolation chamber; The two sets of first sliders are respectively slidably mounted on the two sets of first guide rails; Two sets of second telescopic rods are respectively installed between two sets of first guide rails and two sets of first sliders; Two sets of third springs are respectively fitted onto two sets of second telescopic rods; Two sets of first guide members are respectively installed on the top of the two sets of first sliders; The bottom ends of the two sets of second guide members are rotatably installed on the inner side wall of the box inside the isolation cavity. The ends of the two phase-wire composite optical cables to be connected are fed into the isolation cavity in a backward direction through the S-shaped guidance of the two sets of second guide members and the two sets of first guide members. Then, the ends of the two phase-wire composite optical cables are clamped and fixed by the clamping assembly. When the rear end of the phase-wire composite optical cable is pulled by an external force, the phase-wire composite optical cable is supported by the first guide member, which causes the phase-wire composite optical cable to move the first guide member. After the first guide member moves, it causes the first slider to slide and compresses the second telescopic rod and the third spring. This allows the first guide member to elastically buffer the movement of the phase-wire composite optical cable and reduce the possibility of damage to the phase-wire composite optical cable due to pulling.

[0010] Preferably, the clamping assembly includes a second guide rail, a second slider, a clamping member, and a handle screw; The two sets of second guide rails are respectively installed on the inner side wall of the box inside the isolation chamber; Each pair of second sliders is slidably mounted on a set of second guide rails; Four sets of clamping components are respectively installed at the top of the four sets of second sliders; Four sets of handle screws are screwed onto two sets of second guide rails, and the ends of the four sets of handle screws are rotatably connected to four sets of second sliders. By rotating and adjusting the four sets of handle screws, the handle screws drive the second sliders to slide, thereby clamping and fixing the ends of the two phase-line composite optical cables to be connected by the four sets of clamping components. When the rear of the phase-line composite optical cable is pulled, the front end of the phase-line composite optical cable is clamped and fixed by the clamping components, thus preventing the connection point of the optical fiber and the power line from being pulled.

[0011] Preferably, it also includes a third guide component; Multiple sets of third guide members are respectively installed on the inner side wall of the box inside the optical fiber docking cavity and the power docking cavity; the optical fiber line and the power line are guided by the multiple sets of third guide members in an S-shape, thereby improving the neatness of their arrangement.

[0012] Preferably, it also includes a kit, a limiting protrusion, and a limiting ring; Multiple sets of kits are inserted into two sets of first through holes and four sets of second through holes respectively; Multiple sets of limiting protrusions are respectively set on the outer side wall of multiple sets of components; Multiple sets of limiting rings are respectively fitted onto multiple sets of kits; by allowing the phase line composite optical cable, optical fiber, and power line to pass through the interior of multiple sets of kits, the sealing effect at the junction of the phase line composite optical cable, optical fiber, and power line with the enclosure and partition is improved. By fitting multiple sets of limiting rings onto the ends of multiple sets of kits, it is easy to fix multiple sets of kits between the enclosure and partition. By setting limiting protrusions to limit the limiting rings, the installation firmness of the kit is improved.

[0013] Preferably, a method for installing a phase-coupled composite optical cable protection connection includes the following steps: S1. The ends of the two phase-line composite optical cables to be connected are stripped, and the outer sheath and phase conductor layer are stripped in sequence to expose the internal optical fiber and power line, ensuring that the length of the bare fiber and conductor meets the requirements of the connection operation. S2. Insert the two phase-line composite optical cables into the isolation cavity through the first through holes on both sides of the box; Two optical fibers are passed through two sets of second through holes on the partition and introduced into the optical fiber docking cavity. The two power lines are passed through the other two sets of second through holes on the partition and introduced into the power connection cavity; S3. After the ends of the two optical cables are successively wound around the second guide and the first guide to form an S-shaped guide, they are sent into the isolation cavity; Rotate the handle screw to push the second slider to slide along the second guide rail, so that the clamping parts clamp and fix the ends of the two optical cables respectively. This clamping can prevent subsequent external forces from directly acting on the docking position.

[0014] S4. Inside the fiber optic splicing cavity, the two fiber optic cables are spliced ​​using conventional fusion splicing or mechanical splicing methods. Inside the electrical connection cavity, the two power lines are connected using conventional crimping or welding methods; S5. Install the protective sleeves on the outside of the fiber optic connection point and the power connection point respectively; Place the protective sleeve on top of the support platform, and then cover it with the pressure plate; Tighten the bolts to make the pressure plate and support platform clamp the protective sleeve and fix the docking position; The support platform is equipped with a first telescopic rod and a second spring at its bottom to provide floating elastic support and avoid damage from rigid compression. The first spring is fitted on the bolt to increase installation friction and prevent overpressure. S6. Place the first cover on the top of the isolation chamber, and rotate the two sets of second covers on the top of the fiber optic docking chamber and the power docking chamber using hinges. Secure the first cover and the second cover to the housing with screws to achieve independent sealing of the three chambers.

[0015] Preferably, within the fiber optic docking cavity and the power docking cavity, the fiber optic lines and power lines are arranged in an S-shape around the third guide member to maintain neatness and reduce bending losses.

[0016] Preferably, the kit is inserted into the first through hole and the second through hole, so that the optical cable, optical fiber, and power line pass through the inner hole of the kit respectively. Then, the limiting ring is fitted onto the end of the kit and positioned by the limiting protrusion to achieve sealing and fixation of the wire passage.

[0017] Preferably, a torque wrench is used to control the tightening torque when tightening the S4 bolt.

[0018] Compared with the prior art, the beneficial effects of the present invention are: reducing mutual interference between optical fiber lines and power lines during individual maintenance, improving maintenance efficiency, and reducing signal interference from power lines to optical fiber lines by setting up isolation chambers, thereby improving the operational stability of optical cables.

Detailed Implementation

[0021] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0022] Example 1

[0023] like Figures 1 to 10 As shown, the present invention provides a phase-line composite optical cable protection connector and its installation method. Its overall structure mainly includes a housing 101, a partition 102, a first cover 103, a second cover 104, a hinge 105, a first through hole 106, a second through hole 107, a connection and positioning component, an elastic support component, and a clamping component. The housing 101 serves as the overall load-bearing structure, with an opening at its top. Two sets of partitions 102 are vertically arranged inside the housing 101, dividing the interior of the housing 101 from left to right into three independent chambers: a fiber optic docking chamber, an isolation chamber, and a power docking chamber. The isolation chamber is located between the fiber optic docking chamber and the power docking chamber, serving as physical isolation and signal shielding. A first cover 103 is fitted onto the top of the isolation chamber. Two sets of second covers 104 are rotatably mounted on the left and right sides of the first cover 103 via hinges 105, respectively covering the tops of the fiber optic docking chamber and the power docking chamber. The first cover 103, the second cover 104, and the hinges 105 are respectively attached to the housing 101 by screws. 01 Fixed connection to achieve independent sealing of each chamber. Two sets of first through holes 106 are respectively set on the left and right side walls of the housing 101 and connected to the isolation chamber for cable to pass through. Each set of partitions 102 is provided with two sets of second through holes 107 for the optical fiber and power line in the cable to pass through respectively. The connection positioning component is set inside the housing 101 and is used to fix the optical fiber and power line docking positions. The elastic support component is set inside the housing 101 and is used to provide elastic support and buffer for the phase line composite optical cable. The clamping component is set inside the housing 101 and is used to clamp and fix the end of the phase line composite optical cable to prevent external force from affecting the docking reliability.

[0024] Example 1

[0025] like Figures 1 to 10 As shown, the connection positioning assembly includes a base 201, a support platform 202, a protective sleeve 203, a pressure plate 204, an internal thread seat 205, a bolt 206, a first spring 207, a first telescopic rod 208, and a second spring 209. Two sets of bases 201 are fixedly installed on the inner sidewalls of the housing 101 inside the fiber optic docking cavity and the power docking cavity, respectively, providing the installation foundation for the entire positioning assembly. Two sets of support platforms 202 are slidably installed on the two sets of bases 201 and are used to support the protective sleeve 203. Two sets of protective sleeves 203 are placed on the tops of the two sets of support platforms 202 and are used to cover and protect the fiber optic cable docking point and the power cable docking point. Two sets of pressure plates 204 are placed on the two sets of protective sleeves 207 and 208, respectively. 3. The top is used to press the protective sleeve 203 from above. Multiple sets of internal thread seats 205 are fixedly installed on the outer side walls of the two sets of bases 201. Multiple sets of bolts 206 pass through the two sets of pressure plates 204 and are screwed onto the multiple sets of internal thread seats 205 to provide clamping force. Multiple sets of first springs 207 are respectively fitted on the multiple sets of bolts 206 and located between the pressure plate 204 and the head of the bolt 206 to provide elastic clamping and anti-loosening friction. Multiple sets of first telescopic rods 208 are set between the bottom wall of the box 101 and the support platform 202 and are used to guide the up and down floating of the support platform 202. Multiple sets of second springs 209 are respectively fitted on the multiple sets of first telescopic rods 208 and are used to provide elastic support force for the support platform 202. The support platform 202 forms a floating support structure through the first telescopic rod 208 and the second spring 209, so that the support platform 202 can float up and down relative to the base 201, thereby providing flexible buffer when the pressure plate 204 presses down, and avoiding damage to the docking point caused by rigid compression. In this embodiment, the operation of the phase-wire composite optical cable protection connector is as follows: The ends of the two phase-wire composite optical cables to be connected are stripped, and the outer sheath and phase conductor layer are peeled off sequentially to expose the internal optical fiber and power line. Then, the two phase-wire composite optical cables are inserted into the isolation cavity through two sets of first through holes 106, and the two optical fibers are introduced into the optical fiber connection cavity through two sets of second through holes 107 on the partition 102. Simultaneously, the two power lines are introduced into the power connection cavity through the other two sets of second through holes 107 on the partition 102. In the optical fiber connection cavity, the two optical fibers are connected using conventional fusion splicing or mechanical splicing methods. In the power connection cavity, the two power lines are connected using conventional crimping or welding methods. After connection, two sets of protective sleeves 203 are respectively fitted outside the optical fiber connection position and the power line connection position. The two sets of protective sleeves 203 are placed on the top of the two sets of support platforms 202 respectively. Then, the two sets of pressure plates 204 are pressed onto the two sets of protective sleeves 203 respectively. By tightening multiple sets of bolts 206, the pressure plates 204 and the support platforms 202 cooperate to clamp the protective sleeves 203 to fix the docking position. During this process, the first telescopic rod 208 and the second spring 209 at the bottom of the support platform 202 provide floating elastic support to avoid rigid compression damage to the docking point. At the same time, the first spring 207 fitted on the bolts 206 increases the installation friction to prevent overpressure and loosening. Then, the first cover 103 is installed on the top of the isolation cavity, and the two sets of second covers 104 are rotated and installed on the top of the fiber optic docking cavity and the power docking cavity through the hinges 105. The first cover 103 and the second cover 104 are fixed and locked to the housing 101 with screws to achieve independent sealing of the three chambers.

[0026] The technical effect of this embodiment is that by dividing the interior of the housing 101 into three independent chambers—the optical fiber docking chamber, the isolation chamber, and the power docking chamber—effective isolation between the optical fiber and the power line in physical space is achieved, reducing the electromagnetic interference of the strong power line signal on the weak optical fiber signal and improving the stability of the optical cable operation. Meanwhile, the three chambers are equipped with independent first covers 103 and second covers 104. When it is necessary to inspect and maintain the fiber optic cable or power line separately, only the corresponding chamber cover needs to be opened. There is no need to disassemble the connector as a whole, which avoids damage to the sealing structure of other chambers, reduces mutual interference when the fiber optic cable and power line are maintained separately, and improves the efficiency and economy of inspection and maintenance. The cooperative structure of base 201, support platform 202, pressure plate 204, bolt 206 and internal thread seat 205 achieves reliable positioning and fixation of protective sleeve 203, ensuring long-term stability of the docking position. The floating support structure composed of first telescopic rod 208 and second spring 209, as well as the elastic pressing structure of first spring 207, avoids mechanical damage to optical fiber and power docking point caused by rigid compression, thus improving the protective reliability of the docking device.

[0027] Example 2

[0028] like Figures 1 to 10 As shown, based on Embodiment 1, this embodiment mainly involves the specific structure and operation mode of the elastic support assembly and clamping assembly. The elastic support assembly includes a first guide rail 301, a first slider 302, a second telescopic rod 303, a third spring 304, a first guide member 305, and a second guide member 306. The two sets of first guide rails 301 are respectively fixedly installed on the front and rear inner side walls of the box 101 in the isolation cavity and extend horizontally in the left and right direction. The two sets of first sliders 302 are respectively slidably installed on the two sets of first guide rails 301 and can slide left and right along the first guide rails 301. The two sets of second telescopic rods... Two sets of first guide rails 303 are respectively disposed between the ends of the two sets of first guide rails 301 and the two sets of first sliders 302 and are used to provide guidance and reset force for the sliding of the first sliders 302. Two sets of third springs 304 are respectively mounted on the two sets of second telescopic rods 303 and are used to apply elastic reset force to the first sliders 302. Two sets of first guide members 305 are respectively fixedly installed on the top of the two sets of first sliders 302 and are used to guide and support the phase line composite optical cable. The bottom ends of the two sets of second guide members 306 are respectively rotatably installed on the inner side wall of the box 101 in the isolation cavity and are used to guide the phase line composite optical cable to turn. Furthermore, the clamping assembly includes a second guide rail 401, a second slider 402, a clamping member 403, and a handle screw 404. Two sets of second guide rails 401 are respectively fixedly installed on the front and rear inner side walls of the housing 101 in the isolation cavity and extend horizontally in the left and right direction. Each pair of second sliders 402 are slidably installed on a set of second guide rails 401 and can slide left and right along the second guide rails 401. Four sets of clamping members 403 are respectively set at the top of the four sets of second sliders 402 and are used to clamp the end of the phase line composite optical cable. Four sets of handle screws 404 are respectively screwed on the two sets of second guide rails 401 and the ends of the handle screws 404 are respectively rotatably connected to the four sets of second sliders 402. By rotating the handle screws 404, the second sliders 402 can be pushed to slide along the second guide rails 401, thereby realizing the clamping and loosening of the clamping member 403. Furthermore, it also includes multiple sets of third guide members 501, which are respectively disposed on the inner sidewalls of the housing 101 inside the optical fiber docking cavity and the power docking cavity and are used to guide the optical fiber line and the power line in an S-shaped arrangement to keep them neat and reduce bending loss. Furthermore, it also includes a kit 601, a limiting protrusion 602, and a limiting ring 603. Multiple kits 601 are respectively inserted into two sets of first through holes 106 and four sets of second through holes 107 for phase-line composite optical cables, optical fibers, and power lines to pass through. Multiple limiting protrusions 602 are respectively disposed on the outer side walls of multiple kits 601 and serve a positioning function. Multiple limiting rings 603 are respectively fitted onto the ends of multiple kits 601 and limited by the limiting protrusions 602 to achieve sealing and fixing of the wire passage.

[0029] In this embodiment, the operation of the phase-wire composite optical cable protection connector is as follows: The ends of the two phase-wire composite optical cables to be connected are guided by two sets of second guide members 306 and two sets of first guide members 305 to form an S-shaped path before being sent into the isolation cavity. Then, the handle screw 404 is rotated to push the second slider 402 to slide along the second guide rail 401, causing the clamping member 403 to clamp and fix the ends of the two phase-wire composite optical cables to prevent subsequent external pulling from directly acting on the connection position. When the rear end of the phase-wire composite optical cable is pulled by an external force, the phase-wire composite optical cable... The phase-line composite optical cable drives the first guide member 305 to move. The first guide member 305 drives the first slider 302 to slide along the first guide rail 301 and compress the second telescopic rod 303 and the third spring 304. The elastic restoring force of the third spring 304 is used to buffer and absorb energy from the sudden movement of the phase-line composite optical cable, thereby reducing the risk of damage to the phase-line composite optical cable due to pulling. At the same time, the optical fiber line and the power line are arranged in an S-shape by passing through the third guide member 501 in the optical fiber docking cavity and the power docking cavity respectively to keep them neat and reduce bending loss. In addition, the kit 601 is inserted through the first through hole 106 and the second through hole 107, and the optical cable, optical fiber and power line are respectively passed through the inner hole of the kit 601. Then, the limiting ring 603 is fitted onto the end of the kit 601 and positioned by the limiting protrusion 602, so as to seal and fix the wire threading part to prevent moisture and debris from entering the inside of the box 101 along the wire threading hole.

[0030] The technical effect of this embodiment is that, through the cooperative structure of the first guide rail 301, the first slider 302, the second telescopic rod 303, the third spring 304 and the first guide member 305, the elastic buffer function of the phase line composite optical cable under tension is realized, absorbing the instantaneous pulling energy generated by external factors such as wind swing and construction misoperation, and avoiding the pulling force being directly transmitted to the optical fiber and power connection point. The manual clamping structure, consisting of the second guide rail 401, the second slider 402, the clamping member 403 and the handle screw 404, enables reliable fixing of the end of the phase line composite optical cable, further ensuring that the docking position is not disturbed by external forces. The S-shaped arrangement of optical fiber and power lines is guided by the third guide 501, which keeps the internal circuitry neat and orderly, reduces bending loss, and improves the transmission quality of optical and electrical signals. The threading sealing structure, consisting of kit 601, limiting protrusion 602 and limiting ring 603, effectively seals and fixes the first through hole 106 and the second through hole 107, preventing moisture and dust from entering the cabinet through the threading hole. At the same time, the modular design of the fiber optic docking cavity, isolation cavity and power docking cavity makes each functional area independent, which is convenient for individual maintenance and replacement according to actual needs.

[0031] The phase-wire composite optical cable protection connector and its installation method of the present invention have the following complete operation process during overall operation: First, the ends of the two phase-wire composite optical cables to be connected are stripped, and the outer sheath and phase conductor layer are peeled off in sequence to expose the internal optical fiber and power line, ensuring that the length of the bare fiber and conductor meets the requirements of the connection operation. Then, the two phase-wire composite optical cables are inserted into the isolation cavity through the first through holes 106 on both sides of the housing 101. The two optical fibers are introduced into the optical fiber connection cavity through two sets of second through holes 107 on the partition 102, and the two power lines are introduced into the optical fiber connection cavity through the other two sets of second through holes 107 on the partition 102. 07. The two optical cables are introduced into the power connection cavity, and then the ends of the two optical cables are sequentially guided through the second guide member 306 and the first guide member 305 to form an S-shape before being sent into the isolation cavity. The handle screw 404 is rotated to push the second slider 402 to slide along the second guide rail 401, so that the clamping member 403 clamps and fixes the ends of the two optical cables respectively to prevent subsequent external force from directly acting on the connection position.

The bottom of the support platform 202 is provided with a first telescopic rod 208 and a second spring 209 to provide floating elastic support and avoid rigid compression damage. The first spring 207 is fitted on the bolts 206 to increase the installation friction and prevent overpressure. When tightening the bolts 206, it is preferable to use a torque wrench to control the tightening torque to ensure that each bolt 206 is subjected to uniform force. The optical fiber and power line are wound around the third guide member 5 in the optical fiber docking cavity and the power docking cavity. 01. An S-shaped arrangement is adopted to maintain neatness and reduce bending loss. The kit 601 is inserted through the first through hole 106 and the second through hole 107 so that the optical cable, optical fiber, and power line pass through the inner hole of the kit 601 respectively. Then, the limiting ring 603 is fitted onto the end of the kit 601 and positioned by the limiting protrusion 602 to achieve sealing and fixation of the wire passage. Finally, the first cover 103 is installed on the top of the isolation cavity, and the two sets of second covers 104 are rotated and installed on the top of the optical fiber docking cavity and the power docking cavity through the hinge 105. The first cover 103 and the second cover 104 are fixed and locked to the box 101 with screws to achieve independent sealing of the three chambers.
