Description

Technical Field

[0001] This utility model relates to the field of inverter topology, specifically to an anti-detachment interface for inverter topology installation. Background Technology

[0002] An inverter is a converter that transforms DC power into AC power with fixed frequency and voltage or frequency and voltage regulation. It consists of an inverter bridge, control logic, and filter circuits. When connecting multiple inverters, a topology is required. A topology is the physical layout that connects various devices such as computers to each other using transmission media. It refers to the geometric shape formed during the interconnection process and can represent the network configuration of network servers and workstations and their interconnections.

[0003] Chinese patent CN215497345U discloses an anti-drop-off connector for a high-frequency bandwidth wireless network topology, including a wireless network device. One end of the wireless network device has two sets of anti-drop-off ports. The top of each of the two sets of anti-drop-off ports has a first groove. A rotating shaft is located inside the first groove, and one end of the rotating shaft has a take-up / release wheel. In use, two sets of arc-shaped clamping blocks are brought close together to clamp the network cable, thus securing it. An auxiliary rotating rod on an auxiliary turntable is pressed down, causing one end of the auxiliary rotating rod to insert into a positioning groove, facilitating the positioning and clamping of the network cable. This effectively prevents the network cable from detaching from the wireless network device, making it convenient to use. The ventilation holes on the wireless network device, with dustproof plates inside, prevent external dust from entering and causing poor contact.

[0004] In actual use, the anti-detachment interface of the aforementioned patent relies solely on external clamping to secure the cable and prevent it from falling off. This results in the connection end still experiencing significant tension when exposed to external pulling force, causing the connection position to wobble and making the connection unstable. Therefore, it does not meet the current requirements. To address this, we propose an anti-detachment interface for inverter topology installation. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment interface for inverter topology installation. External tension will cause the anti-detachment plate to rotate around the damping shaft. During the rotation, the tension can be limited directly by the damping between the damping shaft and the support frame. The tension is detected by the rotation sensor, which can prevent continuous pulling and ultimately allow the force to be borne by the slot. After continuous tension is detected, the abnormal indicator light at the connection end can be activated to remind the surrounding users, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-detachment interface for inverter topology installation, comprising an inverter housing, wherein a topology connection structure groove is provided on one side of the front end of the inverter housing, and the topology connection structure groove is embedded in one side of the inside of the inverter housing;

[0007] It also includes damping shafts, which are disposed on both sides inside the groove of the topological connection structure. Both ends of the two damping shafts are provided with support frames, and one side of each of the two support frames is rotatably connected to one side of the damping shaft. One end of one of the support frames is provided with a rotation sensor, and the output shaft of the rotation sensor is welded and fixed to one end of the damping shaft. There are two damping shafts, and the upper end of each of the two damping shafts is provided with a slot.

[0012] Preferably, a sliding support rod is provided on one side of the outer side of the fixing ring, and the outer side of the sliding support rod is slidably connected to the inner side of the fixing ring. A fitting spring is provided between the fixing ring and the second cable placement groove, and the two ends of the fitting spring are welded and fixed to the fixing ring and the anti-drop plate, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model has support frames at both ends of the damping shaft, with a rotation sensor on one side of one of the support frames. An anti-detachment plate is installed at the lower end of the damping shaft. In actual use and to prevent detachment, the external tension will cause the anti-detachment plate to rotate around the damping shaft. During the rotation, the tension can be limited by the damping between the damping shaft and the support frame. The rotation sensor detects the tension, which can prevent continuous pulling and ultimately allow the force to be borne by the slot. After continuous tension is detected, the abnormal indicator light at the connection end can be activated to remind the surrounding users.

[0017] 2. This utility model features a first cable placement groove at the upper end of the anti-drop plate, a second cable placement groove in the middle of the anti-drop plate, and a third cable placement groove at the lower end of the anti-drop plate. During cable installation, cables of different sizes can be pressed according to the bending state of the first, second, and third cable placement grooves and placed inside. The cables are then fixed by pressing them with a fixing ring and a pressing plate. This design adapts to cables of different diameters while improving anti-drop efficiency. Furthermore, when subjected to tension, the force is initially limited by the anti-drop plate protruding from the second cable placement groove, preventing the force from being directly transmitted and borne by the slot.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To address the issue that existing anti-detachment connectors rely solely on external clamps to secure cables during practical use, which can lead to significant tension on the connector when subjected to external pulling forces, causing the connection to wobble and resulting in poor stability, please refer to [the relevant documentation / reference needed]. Figure 1 , Figure 2 and Figure 3 This embodiment provides the following technical solution:

[0024] An anti-detachment interface for inverter topology installation includes an inverter housing 1. A topology connection structure groove 2 is provided on one side of the front end of the inverter housing 1, and the groove 2 is embedded inside one side of the inverter housing 1. It also includes damping shafts 4, which are disposed on both sides inside the topology connection structure groove 2. Support brackets 3 are provided at both ends of the two damping shafts 4, and one side of each support bracket 3 is rotatably connected to one side of the damping shaft 4. A rotation sensor 5 is provided at one end of one support bracket 3, and the output shaft of the rotation sensor 5 is welded and fixed to one end of the damping shaft 4. Two damping shafts 4 are provided. Both damping shafts 4 have slots 11 at their upper ends. The inverter housing 1 has a connection end abnormality indicator light 19 at its upper end. The connection end abnormality indicator light 19 is electrically connected to the rotation sensor 5. External pulling force will cause the anti-drop plate 18 to rotate around the damping shaft 4. During the rotation, the pulling force can be directly limited by the damping between the damping shaft 4 and the support frame 3. The rotation sensor 5 detects the pulling force, which can prevent continuous pulling and eventually make the force bear by the slot 11. After continuous pulling force is detected, the connection end abnormality indicator light 19 can be activated to remind the surrounding users.

[0025] To address the issue of low cable installation efficiency in existing systems, please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 This embodiment provides the following technical solution:

[0026] A damping shaft 4 has an anti-drop plate 18 at its lower outer end. A first cable placement groove 6 is provided at the upper inner end of the anti-drop plate 18, and a third cable placement groove 8 is provided at the lower inner end of the anti-drop plate 18. A second cable placement groove 7 is provided between the third cable placement groove 8 and the first cable placement groove 6. The second cable placement groove 7, the third cable placement groove 8, and the first cable placement groove 6 all extend into the interior of the anti-drop plate 18. A first receiving rail 12 is provided at the upper end of the third cable placement groove 8, and a second receiving rail 13 is provided on one side of the first cable placement groove 6. A fixing ring 15 is provided in the middle of the interior of both the second receiving rail 13 and the first receiving rail 12. Cables of different sizes can be pressed directly according to the bending state of the first cable placement groove 6, the second cable placement groove 7, and the third cable placement groove 8, and placed inside to complete the fixing and restriction, thereby improving the installation efficiency of the cables.

[0027] A sliding support rod 14 is provided on one side of the fixed ring 15, and the outside of the sliding support rod 14 is slidably connected to the inside of the fixed ring 15. A contact spring 17 is provided between the fixed ring 15 and the second cable placement groove 7, and the two ends of the contact spring 17 are welded and fixed to the fixed ring 15 and the anti-drop plate 18, respectively. A pressing piece 16 is provided on the other side of the fixed ring 15, and the pressing piece 16 is welded and fixed to the fixed ring 15. There are two sliding support rods 14. One end of one sliding support rod 14 is provided with a first pressure sensor 9, and the other end of the other sliding support rod 14 is provided with a second pressure sensor 10. The second pressure sensor 10 and the first pressure sensor 9 are both electrically connected to the connection end abnormal indicator light 19. The fixed ring 15 can slide within the sliding support rod 14 to accommodate cables of different diameters.

[0028] Working principle: During the installation of the inverter topology, according to... Figure 1 , Figure 2 and Figure 3To improve the anti-detachment effect, the anti-detachment plate 18 is fitted to one side of the groove 2 inside the topological connection structure. This fit ensures that when the cables in the first cable placement groove 6, the second cable placement groove 7, and the third cable placement groove 8 are pulled, the anti-detachment plate 18 will first rotate around the damping shaft 4. During rotation, the resistance at both ends of the damping shaft 4 initially limits the pulling force, and the rotation sensor 5 at one end of the damping shaft 4 detects the rotation. As rotation is continuously detected, a signal is sent to the connection end anomaly indicator light 19. Upon receiving the signal, the connection end anomaly indicator light 19 illuminates directly, alerting nearby users to avoid continued pulling that could cause detachment. To improve cable installation efficiency, during installation... During the process, after the cable's connecting end is electrically connected to the slot 11, the cable's outer surface is placed sequentially into the first cable placement groove 6, the second cable placement groove 7, and the third cable placement groove 8. Then, the elasticity of the springs 17 in the first and second receiving rails 12 and 13 pushes the fixing ring 15, causing the fixing ring 15 to move laterally on the sliding support rod 14 until the sliding support rod 14 is in contact with the outer surface of the cable. At the same time, the sliding support rod 14 will drive the pressing piece 16, causing the pressing piece 16 to move to the upper end of the cable, adapting to and restricting the cable. When the cable is pulled, the tension will be preferentially restricted by the anti-drop plate 18 protruding in the second cable placement groove 7, preventing the force from being directly borne by the slot 11 and preventing it from falling off.
