Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a lightning protection device for routing and switching equipment. Background Technology

[0002] A switch is a network device used for forwarding electrical signals. It can provide a dedicated electrical signal path for any two network nodes connected to the switch. The most common type of switch is the Ethernet switch, and other common types include telephone voice switches and fiber optic switches.

[0003] In the current field of network equipment surge protection, many existing devices have significant shortcomings in their grounding cable design. The length of these grounding cables is often predetermined. If the length is too short, staff must manually connect additional cables to extend it. This process is not only time-consuming and labor-intensive, but improper operation during connection, such as loose connections, can create significant contact resistance, severely compromising surge protection performance and preventing lightning current from smoothly conducting to the ground. If the length is too long, redundant cables can only be haphazardly coiled around the server rack, occupying space, affecting the overall layout of the server room, and easily causing damage to the outer sheath due to mutual compression and friction between cables. In the event of a lightning strike, this can also affect current conduction and compromise surge protection. Furthermore, manually cutting excessively long cables requires specialized tools and a high level of skill. An incorrect cut can render the entire cable unusable, wasting resources and delaying the normal installation and use of surge protection equipment. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightning strike protection device for routing and switching equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightning protection device for routing and switching equipment includes a placement block with a placement groove. A movable frame for fixing the routing equipment is located within the placement groove via a pressing mechanism. A winding groove is located at the bottom of the placement block, and a winding roller rotatably rotates within the winding groove. A grounding cable is wound on the winding roller. An opening communicating with the winding groove is located on the outer wall of the placement block, and a screw rotatably rotates within the opening. The screw is connected to the winding roller via a rotating mechanism. A drive motor connected to the screw is located on the outer wall of the placement block, and a movable frame cooperating with the grounding cable is threaded onto the screw via a limiting mechanism.

[0007] Preferably, the compression mechanism includes a compression spring disposed in the placement groove, with both ends of the compression spring connected to the outer wall of the movable frame and the inner wall of the placement groove, respectively.

[0008] Preferably, the rotating mechanism includes a synchronous pulley mounted on the placement block and connected to the screw and the winding roller, and the two synchronous pulleys are connected by a synchronous belt.

[0009] Preferably, the limiting mechanism includes a limiting rod disposed within the opening, the limiting rod being parallel to the screw and slidingly penetrating the movable frame.

[0010] Preferably, one end of the grounding cable passes through the winding roller and the placement block and extends to one side of the placement block, and one end of the grounding cable is rotatably connected to a connecting cable that is connected to the movable frame.

[0011] Preferably, the movable frame is L-shaped and is provided with a protective rubber pad.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the linkage design of the drive motor, screw and winding roller, the grounding cable can be automatically wound up and down according to the installation height, avoiding manual cutting or extension.

[0014] 2. The compression spring combined with the L-shaped movable frame provides stable clamping force; the rubber pad prevents scratches on the equipment surface.

[0015] 3. The synchronous pulley and synchronous belt synchronize the rotation of the screw and the rotation of the winding roller, ensuring that the grounding cable is neatly wound and unwound, avoiding knots or tangles. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A lightning protection device for routing and switching equipment includes a placement block 1 with a placement groove 2. A movable frame 4 for fixing a routing device 3 is located within the placement groove 2 via a pressing mechanism. The routing device 3 is a prior art product; the attached diagram is only a structural schematic, and the specific structure can be found in existing technology. The bottom of the placement block 1 has a winding groove 15, within which a winding roller 16 is rotatably mounted. A grounding cable 9 is wound on the winding roller 16. The outer wall of the placement block 1 has an opening 5 communicating with the winding groove 15. A screw 6 is rotatably mounted within the opening 5, connected to the winding roller 16 via a rotating mechanism. A drive motor 13 connected to the screw 6 is located on the outer wall of the placement block 1.

[0022] A movable frame 8, which mates with the grounding cable 9, is threaded onto the screw 6 via a limiting mechanism. As shown in the figure, the grounding cable 9 slides through the movable frame 8 and is rotated by the movable frame 8, changing its position from horizontal to vertical.

[0023] The compression mechanism includes a compression spring 14 disposed within the placement slot 2, with both ends of the compression spring 14 connected to the outer wall of the movable frame 4 and the inner wall of the placement slot 2, respectively. The movable frame 4 has an L-shaped design and is equipped with a protective rubber pad. The elastic potential energy provided by the compression spring 14 compresses the movable frame 4, ensuring the stability of the routing device 3 when placed within the placement slot 2. The rubber pad provides elastic protection, preventing damage to the surface of the routing device 3 caused by the clamping of the movable frame 4, and its L-shaped design prevents vertical movement and detachment from the movable frame 4.

[0024] The rotating mechanism includes synchronous pulleys 10 mounted on the placement block 1 and connected to the screw 6 and the winding roller 16. The two synchronous pulleys 10 are connected by a synchronous belt 11. The synchronous pulleys 10 and the synchronous belt 11 enable the power transmission of the drive motor 13, allowing the winding roller 16 to rotate when the drive motor 13 drives the screw 6 to rotate.

[0025] The limiting mechanism includes a limiting rod 7 disposed within the opening 5. The limiting rod 7 is parallel to the screw 6 and slides through the movable frame 8. The limiting rod 7 limits the movement of the movable frame 8, preventing the movable frame 8 from rotating along with the screw 6.

[0026] One end of the grounding cable 9 passes through the winding roller 16 and the placement block 1 and extends to one side of the placement block 1. The other end of the grounding cable 9 is rotatably connected to the connecting cable 12, which is connected to the movable frame 4. When the routing device 3 is subjected to a current surge, it is transmitted through the movable frame 4 (which is made of copper and can conduct current) to the connecting cable 12, which in turn transmits the current to the grounding cable 9, and finally conducts it to the ground for current release.

[0027] Because one end of the grounding cable 9 passes through the placement block 1 and the winding roller 16, the grounding cable 9 can be wound and unwound when the winding roller 16 rotates.

[0028] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods of each component adopt mature methods in the prior art, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0029] When this utility model is in use, the routing device 3 is placed in the placement slot 2 and is clamped and fixed by the movable frame 4. The current surge on the routing device 3 can be transmitted to the grounding cable 9 through the movable frame 4 and the connecting cable 12, and finally the current surge is conducted to the ground for current release.

[0030] The distance between the components such as the placement block 1 and the routing device 3 and the ground depends on the actual situation. When the distance is relatively high, the grounding cable 9 needs to be extended to a certain extent, and when the distance is relatively low, the grounding cable 9 needs to be shortened to a certain extent.

[0031] In this scheme, the drive motor 13 can drive the screw 6 to rotate, and together with the synchronous pulley 10 and the synchronous belt 11, drive the winding roller 16 to rotate. The rotation of the screw 6 can realize the movement of the moving frame 8 (when releasing the wire, the moving frame 8 moves closer to the drive motor 13, and when retracting the wire, the moving frame 8 moves away from the drive motor 13), which can adapt to the winding and releasing of the grounding cable 9 on the winding roller 16, and can make the winding and releasing neat.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
