Description

Technical Field

[0001] This utility model belongs to the field of power communication engineering construction technology, specifically, it relates to a power communication cable junction box. Background Technology

[0002] A power communication cable junction box is a terminal device for distribution cables or optical cables. Its core function is to branch the signal or current of the main cable into multiple outputs and connect them to end users or equipment.

[0003] The prior art discloses a cable distribution box including a box body (CN220172806U), a box cover, a splitter, a port protection ring, an indicator light, an observation window, a connector, a locking component, and a heat dissipation assembly. The heat dissipation assembly includes a dustproof mesh, a motor, a cooling fan, and a support cover. When using this utility model, the cable is passed through the cable through the through hole and connected to the splitter. When the splitter splits the cable, it will generate a certain amount of heat. The heat will drive the cooling fan to rotate on the support cover through the output end of the motor. The rotation of the cooling fan will guide the air inside, allowing the heat generated during the splitting to be dissipated in time. During the airflow, the dustproof mesh can isolate some dust in the air. The box body and the box cover are fixed by the cooperation of the locking component and the connector. The working status of the splitter can be judged by observing the flashing of the indicator light through the observation window.

[0004] The search revealed that the existing technology uses a static sealed structure and relies on a cooling fan for heat dissipation, but it does not consider the problem of water seepage under rain impact. This leads to water accumulation and long-term corrosion of components or failure of internal cable insulation. Furthermore, there is a lack of stabilization measures between the cable and the through hole. In windy weather, the cable is prone to loosening and pulling in the through hole, causing the connection between the cable and the splitter to fall off, resulting in a short circuit in the output.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A power communication cable junction box, including

[0008] The box body has a hinged lid, and a spiral guide groove is provided on the side of the lid away from the box body. A heat dissipation device is embedded in one side of the outer side of the box body. A splitter is installed on one side of the inner side of the box body. A port protection ring is fixed on one side of the splitter's splitting hole. A tensile-resistant structure for protecting the cable and preventing it from falling off and a clamping structure for fixing and holding the cable according to its size are installed on the other side of the inner side of the box body.

[0009] The tensile-resistant structure includes a movable seat, a slide rail, and an insulating collar. The slide rail is fixedly installed on the inner bottom surface of the box, the movable seat is slidably installed on the slide rail, and the insulating collar is movably installed inside the movable seat. The movable seat is magnetically movable within the box.

[0010] In a preferred embodiment of the present invention, the clamping structure includes two horizontally symmetrically arranged clamping members and two vertically symmetrically arranged clamping members. Each clamping member includes a soft clamping block and a compression spring. At least three compression springs are arrayed and fixed on the side of the soft clamping block near the box body. The soft clamping block is elastically connected to the box body through the compression springs.

[0011] In a preferred embodiment of this utility model, a conduit is fixedly provided on one side of the box body, and a cable is inserted and clamped inside the conduit. A clamping groove is provided inside the box body on the side near the conduit. A pair of horizontal clamping fasteners are installed on one side of the clamping groove, and a pair of vertical clamping fasteners are installed on the other side of the clamping groove. The soft clamping block is elastically connected to the clamping groove by a compression spring.

[0012] In a preferred embodiment of this utility model, two support plates and two wire plates are symmetrically fixed to the bottom surface of the inner side of the box. A slide rail is fixedly connected between the two support plates. The two wire plates are arranged in an S-shape, and the cable is wound around the outer curved surface of the two wire plates.

[0013] In a preferred embodiment of this utility model, a magnetic ring is installed on the inner wall of the box body near the support plate, a slider is fixedly provided on the bottom surface of the movable seat, the movable seat slides in conjunction with the slide rail through the slider, and another magnetic ring is fixedly provided on the side of the movable seat near the box body, with the two magnetic rings having the same pole.

[0014] In a preferred embodiment of this utility model, a magnet and a buffer spring are fixedly provided on each side of the movable seat, and another magnet is fixedly provided on the side of each of the two support plates near the movable seat. The movable seat is magnetically repelled by the magnets on both sides and the magnets on the two support plates. The movable seat is elastically connected to the support plates on both sides by the buffer springs on both sides.

[0015] In a preferred embodiment of this utility model, a stabilizing groove is provided inside the movable seat, and an insulating collar is sleeved inside the movable seat. A plurality of compression springs are fixed in a ring array between the stabilizing groove and the insulating collar, and the stabilizing groove is elastically connected to the insulating collar through the compression springs.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. The anti-tension structure uses the repulsive force between the magnet and the magnetic ring, combined with the elastic deformation clamping of the insulating sleeve and the compression spring, to counteract the lateral pulling force of the cable in strong winds, preventing the cable from falling off the connection end with the splitter. The self-adaptive clamping and contraction of the soft clamp and the compression spring ensure that the cable does not wobble radially within the moving seat, further reducing the risk of poor contact during pulling. The neoprene rubber material of the soft clamp combines elasticity and wear resistance, which not only avoids damage to the cable insulation layer during clamping, but also provides sufficient friction to prevent the cable from slipping.

[0018] 2. The spiral guide groove of the cover can quickly guide rainwater along the spiral path to the edge of the box during heavy rain, preventing rainwater from accumulating on the surface of the cover and seeping in; the heat dissipation device adopts a fanless aluminum fin structure, which dissipates heat through heat conduction, eliminating the risk of rainwater backflow caused by the use of fans in existing technologies, thereby preventing water accumulation inside the box and thus avoiding internal cable insulation failure caused by corrosion of components.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A power communication cable junction box, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0029] The box body 10 has a cover 11 hinged to it. The cover 11 has a spiral guide groove 12 on the side away from the box body 10. A heat dissipation device 16 is embedded in the outer side of the box body 10. A splitter 15 is installed on the inner side of the box body 10. A port protection ring 23 is fixed on the side of the splitter hole of the splitter 15. A tensile structure for protecting the cable and preventing the cable from falling off and a clamping structure for fixing and holding the cable according to its size are installed on the other side of the inner side of the box body 10.

[0030] The tensile-resistant structure includes a movable seat 18, a slide rail 21, and an insulating collar 29. The slide rail 21 is fixedly installed on the inner bottom surface of the box body 10, the movable seat 18 is slidably installed on the slide rail 21, and the insulating collar 29 is movably installed inside the movable seat 18. The movable seat 18 is magnetically movable inside the box body 10.

[0031] Specifically, the spiral guide groove 12 has a spiral structure. When rainwater flows along the surface of the cover 11 to the edge, it can be discharged faster through the spiral path, avoiding stagnation at the joint between the cover 11 and the box body 10. The heat dissipation device 16 uses an aluminum heat dissipation fin assembly for heat dissipation. It conducts heat out of the interior through heat conduction, avoiding the risk of rainwater backflow caused by using a fan for heat dissipation. The port protection ring 23 fixed on the outside of the splitter hole of the splitter 15 is a frustum-shaped rubber structure, which can buffer the radial impact force when the cable is inserted, and prevent the splitter port from being damaged by frequent plugging and unplugging.

[0032] like Figure 5 As shown, the clamping structure includes two horizontally symmetrically arranged clamping members and two vertically symmetrically arranged clamping members. The clamping members include soft clamping blocks 30 and compression springs 31. At least three compression springs 31 are arrayed and fixed on the side of the soft clamping blocks 30 near the box body 10. The soft clamping blocks 30 are elastically connected to the box body 10 through the compression springs 31.

[0033] like Figure 1 and Figure 5As shown, a conduit 14 is fixedly provided on one side of the housing 10. A cable 13 is inserted and clamped inside the conduit 14. A corresponding through hole is opened on the side of the housing 10 near the conduit 14. The cable 13 passes through the through hole and connects to the splitter 15. After the cable 13 passes through the conduit 14, it enters the interior through the corresponding through hole of the housing 10. A clamping groove 32 is opened inside the side of the housing 10 near the conduit 14. A pair of horizontal clamping fasteners are installed on one side of the clamping groove 32, and a pair of vertical clamping fasteners are installed on the other side of the clamping groove 32. The soft clamping block 30 is elastically connected to the clamping groove 32 by a compression spring 31.

[0034] Specifically, the soft clamp 30 is made of neoprene rubber, and an arc-shaped opening is provided on the side near the center of the through hole. The arc-shaped opening fits the curved shape of the cable 13. When the cable 13 passes through the clamping groove 32, the two pairs of soft clamps 30 in the horizontal and vertical directions tighten outward synchronously under the action of their respective compression springs 31. The cable 13 is elastically clamped by wrapping it with multi-directional elastic force, which adapts to the size of the cable 13 and prevents the cable 13 from loosening in the through hole in windy weather.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, two support plates 17 and two wire plates 22 are symmetrically fixed on the bottom surface of the inner side of the box 10. A slide rail 21 is fixedly connected between the two support plates 17. The two wire plates 22 are arranged in an S-shape. The cable 13 is wound around the outer curved surface of the two wire plates 22.

[0036] like Figure 3 and Figure 4 As shown, a magnetic ring 19 is installed on the inner wall of the box 10 near the support plate 17. A slider 24 is fixedly provided on the bottom surface of the movable seat 18. The movable seat 18 slides and engages with the slide rail 21 through the slider 24. Another magnetic ring 19 is fixedly provided on the side of the movable seat 18 near the box 10. The two magnetic rings 19 are set with the same pole.

[0037] like Figure 3 and Figure 4 As shown, a magnet 20 and a buffer spring 26 are fixed on both sides of the movable seat 18, and another magnet 20 is fixed on the side of each of the two support plates 17 near the movable seat 18. The movable seat 18 is magnetically repelled by the magnets 20 on both sides and the magnets 20 on the two support plates 17. The movable seat 18 is elastically connected to the support plates 17 on both sides by the buffer springs 26 on both sides.

[0038] like Figure 4As shown, the movable base 18 has a stabilizing groove 27 inside, and a through hole corresponding to the cable conduit 14 is opened in the center of the movable base 18. The through hole communicates with the stabilizing groove 27. An insulating collar 29 is sleeved inside the movable base 18 and the through hole is also sleeved with an insulating collar 29. Multiple compression springs 28 are fixed in a ring array between the stabilizing groove 27 and the insulating collar 29. The stabilizing groove 27 is elastically connected to the insulating collar 29 through the compression springs 28. The cable 13 passes through the insulating collar 29 and is connected to the splitter 15.

[0039] Specifically, magnets 20 and magnetic rings 19 are respectively attached to the inner wall surface of the box 10 near the support plate 17 and the corresponding side of the movable seat 18. The two magnetic rings 19 and the two pairs of magnets 20 are opposite each other with the same pole, forming a magnetic repulsive force to counteract slight pulling force. Buffer springs 26 are welded between the two sides of the movable seat 18 and the support plate 17. When the movable seat 18 is pulled and slides, the buffer springs 26 stretch to generate a reverse pulling force, which works in conjunction with the magnetic repulsive force to buffer the pull. The two ends of the compression springs 28 are respectively welded to the inner wall of the stabilizing groove 27 and the insulating collar. The outer wall of the 29 allows the insulating collar 29 to elastically deform and shrink to adapt to the size of the cable 13. At the same time, the insulating material isolates the cable 13 from the metal moving seat 18 to prevent leakage. The elastic pressure makes the insulating collar 29 tightly wrap the cable 13 to prevent the cable from shaking inside the moving seat 18. The bottom of the box is fixed with a horizontal slide rail 21 by two support plates 17. The slider 24 at the bottom of the moving seat 18 is embedded in the slide rail 21 and can slide along the axial direction of the cable 13. After the external force is removed, the magnetic repulsion force and the spring restoring force make the moving seat 18 automatically return to its position.
