Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a safety protection device for wide voltage debugging equipment. Background Technology

[0002] In the field of modern electronic equipment research and development and manufacturing, wide-voltage debugging equipment is used for performance testing and parameter calibration of electronic devices that can adapt to different voltage input ranges. It is widely used in power module development, industrial automation control equipment debugging, and new energy vehicle electronic control system testing. Because the equipment needs to operate under multiple voltage conditions during the debugging process, the circuit system faces risks such as overload and short circuit. Therefore, safety protection devices are key components to ensure the stable operation of wide-voltage debugging equipment and the safety of personnel.

[0003] Most wide-voltage debugging equipment on the market currently lacks effective dust and foreign object protection structures. Long-term exposure of wire grooves can easily accumulate dust and debris, leading to poor wire contact, affecting the accuracy of debugging data, and even causing circuit failure. Therefore, a safety protection device for wide-voltage debugging equipment is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a safety protection device for wide voltage debugging equipment, which aims to improve the problem in the prior art where long-term exposure of wire grooves easily leads to the accumulation of dust and debris, resulting in poor wire contact and affecting the accuracy of debugging data.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a safety protection device for a wide voltage debugging equipment, including a circuit breaker, wherein multiple wire slots are provided on both the upper and lower sides of the circuit breaker, a cover plate is rotatably connected above the wire slots, a locking block is fixedly connected to the bottom of the cover plate, multiple fixing components are provided on the inner wall of the circuit breaker, multiple support plates are fixedly connected to the outer walls of both the upper and lower sides of the circuit breaker, an mounting plate is fixedly connected to the outer wall of the support plate, and a clamping component is provided inside the mounting plate; The fixing assembly includes a guide rod, the outer wall of which is fixedly connected to the inner wall of the circuit breaker, a pull plate is slidably connected to the outer wall of the guide rod, a hanging plate is fixedly connected to the outer wall of the pull plate, and a spring is sleeved on the outer wall of the guide rod.

[0006] As a further description of the above technical solution: The clamping assembly includes two connecting rods, the outer walls of which are slidably connected to the inside of the mounting plate. A clamping plate is fixedly connected to one side of the connecting rod, and a limit block is fixedly connected to the other side of the connecting rod. A limit assembly is provided inside the mounting plate.

[0007] As a further description of the above technical solution: The limiting component includes a limiting rod, which is fixedly connected to the inner wall of the mounting plate. The inner wall of the limiting block is slidably connected to the outer wall of the limiting rod, and a spring is sleeved on the outer wall of the limiting rod.

[0008] As a further description of the above technical solution: The mounting plate and the card block are connected.

[0009] As a further description of the above technical solution: One end of the spring is fixedly connected to the inner wall of the circuit breaker, and the other end of the spring is fixedly connected to the pull plate.

[0010] As a further description of the above technical solution: The clamp is arc-shaped.

[0011] As a further description of the above technical solution: One end of the second spring is fixedly connected to the inner wall of the mounting plate, and the other end of the second spring is fixedly connected to the outer wall of the limiting block.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the cover plate and the fixing component work together to close the cover plate before the wire is installed, and a stable fixation is achieved by the engagement of the clip and the hanging plate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a safety protection device for wide-voltage debugging equipment, including a circuit breaker 1. The circuit breaker 1, as the core electrical component of the entire safety protection device, plays a crucial role in automatically disconnecting the circuit and protecting the wide-voltage debugging equipment and related circuit systems in the event of overload, short circuit, or other abnormal conditions. Multiple wire grooves 2 are provided on both the upper and lower sides of the circuit breaker 1. The wire grooves 2 are used to accommodate and guide the wires connected to the circuit breaker 1, providing a fixed laying path for the wires. A cover plate 5 is rotatably connected above the wire grooves 2. The cover plate 5 can be opened and closed around the rotatable connection point with the wire groove 2. Closing the cover plate 5 further protects the wires, preventing dust, debris, etc., from entering the wire grooves 2 and affecting the conductors. For wire connection performance, a locking block 6 is fixedly connected to the bottom of the cover plate 5. The locking block 6 is used to cooperate with the fixing components inside the circuit breaker 1 to fix the cover plate 5 after it is closed. Multiple fixing components are provided on the inner wall of the circuit breaker 1. The fixing components are used to cooperate with the locking block 6 to fix the cover plate 5. Multiple support plates 3 are fixedly connected to the outer walls of the upper and lower sides of the circuit breaker 1. The support plates 3 play a supporting and connecting role, connecting the circuit breaker 1 to the mounting plate 4. The mounting plate 4 is fixedly connected to the outer wall of the support plate 3. The mounting plate 4 is used to fix the entire safety protection device on the wide voltage debugging equipment or other suitable positions. The mounting plate 4 is provided with a clamping component. The clamping component is used to fix the installed wires to ensure that the wire connections are neat and orderly. Reference Figure 2 and Figure 3The fixing component includes a guide rod 9, the outer wall of which is fixedly connected to the inner wall of the circuit breaker 1. The guide rod 9 provides guidance for the sliding of the pull plate 7, ensuring that the pull plate 7 can move along a fixed direction during the sliding process. The pull plate 7 is slidably connected to the outer wall of the guide rod 9, and the pull plate 7 can slide on the guide rod 9. The sliding of the pull plate 7 realizes the connection and separation with the locking block 6. The outer wall of the pull plate 7 is fixedly connected to a hanging plate 8, which is used to hook with the locking block 6 at the bottom of the cover plate 5 to fix the cover plate 5. A spring 10 is sleeved on the outer wall of the guide rod 9. The spring 10 provides elastic force. When the pull plate 7 slides under the action of external force, the pull plate 7 can automatically reset under the action of the elastic force of the spring 10 and maintain the hooked state with the locking block 6.

[0018] Reference Figure 4 The clamping assembly includes two connecting rods 12. The outer wall of the connecting rods 12 is slidably connected to the inside of the mounting plate 4. The connecting rods 12 are used to connect the clamping plate 13 and the limiting block 11, and drive the clamping plate 13 to slide, so as to achieve the effect of clamping the wire. The clamping plate 13 is fixedly connected to one side of the connecting rod 12. The clamping plate 13 is used to clamp the installation wire. Through the relative movement of the two clamping plates 13, the installation wire is clamped and fixed on the mounting plate 4. The limiting block 11 is fixedly connected to the other side of the connecting rod 12. The limiting block 11 is used to limit the sliding range of the connecting rod 12. A limiting component is provided inside the mounting plate 4. The limiting component is used to limit the limiting block 11 and provide elastic force to prevent the limiting block 11 from rotating during the sliding process.

[0019] Reference Figure 4 The limiting component includes a limiting rod 14, which is fixedly connected to the inner wall of the mounting plate 4. The inner wall of the limiting block 11 is slidably connected to the outer wall of the limiting rod 14. The limiting rod 14 provides guidance for the sliding of the limiting block 11, ensuring that the limiting block 11 moves along a fixed direction during the sliding process. A second spring 15 is sleeved on the outer wall of the limiting rod 14, which provides elastic force. When the clamping plate 13 is moved by an external force, the clamping plate 13 can automatically reset under the action of the elastic force of the second spring 15, maintaining the clamping force on the installation wire.

[0020] Reference Figure 2 and Figure 3 The hanging plate 8 and the locking block 6 are connected. When the cover plate 5 is closed, the cover plate 5 is fixed above the wire groove 2 by the connection between the hanging plate 8 and the locking block 6 to prevent the cover plate 5 from being opened accidentally.

[0021] Reference Figure 3One end of spring 10 is fixedly connected to the inner wall of circuit breaker 1, and the other end of spring 10 is fixedly connected to pull plate 7, so that spring 10 can provide elastic restoring force for pull plate 7. When pull plate 7 is subjected to external force and slides along guide rod 9, causing hanging plate 8 to separate from block 6, pull plate 7 can automatically slide back to the initial position under the elastic force of spring 10, driving hanging plate 8 to re-engage with block 6.

[0022] Reference Figure 4 The clamp 13 is arc-shaped, which allows it to better fit the surface of the wire and increase the contact area between the clamp 13 and the mounting component.

[0023] Reference Figure 4 One end of spring 15 is fixedly connected to the inner wall of mounting plate 4, and the other end of spring 15 is fixedly connected to the outer wall of limiting block 11. When clamping plate 13 is subjected to external force, causing limiting block 11 to slide along limiting rod 14, spring 15 is compressed or stretched. After the external force is removed, spring 15 can push limiting block 11 to reset through its own elastic restoring force, thereby causing clamping plate 13 to reset and maintaining the clamping force on the mounting component.

[0024] Working principle: When the safety protection device of the wide voltage debugging equipment needs to be used, the circuit breaker 1 is installed on the wide voltage debugging equipment. Then, when it is necessary to make an electrical connection between the circuit breaker 1 and the wide voltage debugging equipment, the pull plate 7 is moved. When the pull plate 7 is moved, it will slide, which will further drive the hanging plate 8 to slide on the outer wall of the guide rod 9. At the same time, the spring 10 is compressed, so that the spring 10 stores potential energy. When the hanging plate 8 slides out of the engagement state with the locking block 6, the cover plate 5 is rotated upward to expose the wire groove 2. Then, the connecting wire is passed through the mounting plate 4 and inserted into the wire groove 2. Then, the bolt on the front side of the circuit breaker 1 is tightened to fix the wire to the inner wall of the circuit breaker 1.

[0025] When the wire passes through the inside of the mounting plate 4, the outer wall of the wire will press the two clamps 13 outward. When the clamps 13 are pressed, the connecting rod 12 will drive the limiting block 11 to slide on the outer wall of the limiting rod 14. When the limiting rod 14 slides, it will drive the second spring 15 to be compressed, so that the second spring 15 stores potential energy. At the same time, the second spring 15 will also release the stored potential energy, thereby pushing the clamps 13 to slide relative to each other and clamp and fix the wire.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
