Abstract
Description
Technical Field
[0001] This utility model relates to the field of power grid fluctuation protection technology, and in particular to an anti-power fluctuation device. Background Technology
[0002] In modern industrial production, the stability of power supply plays a crucial role in the normal operation of equipment and the continuity of production. As a key device to ensure the stable operation of the power system, anti-voltage fluctuation devices can effectively cope with short-term voltage fluctuations and drops in the power grid, avoiding equipment downtime, production line interruptions, and other problems caused by voltage fluctuations, thereby reducing economic losses.
[0003] However, existing anti-voltage fluctuation devices have several problems in practical use. Regarding wiring, traditional devices often require individually clamping the wires in each wiring slot, which is inefficient and prone to insecure clamping of some wires, affecting the stability of the electrical connection. In terms of safety, releasing the clamped wires usually requires tools, increasing complexity and posing a risk of electric shock to operators who may come into direct contact with the wiring panel. Furthermore, during prolonged operation, the wiring slots and other parts of the anti-voltage fluctuation device generate heat. If this heat cannot be dissipated effectively, it will affect the device's performance and lifespan; existing devices often lack effective heat dissipation designs.
[0004] Therefore, it is necessary to design an anti-power fluctuation device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip device. This invention can compress the wires in the wiring slot in one go, and no tools are needed when releasing the compression. It can also prevent human hands from coming into contact with the wiring board, thus avoiding safety accidents. In addition, airflow is used to cool the wiring slot during use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An anti-voltage fluctuation device includes a housing, within which a circuit board is disposed. Two terminal blocks are fixedly connected to the front side of the housing, and the two terminal blocks are electrically connected to the circuit board via wires. Each of the two terminal blocks has multiple wiring slots on its front side. Each terminal block has a wire clamping assembly, which includes a rectangular plate disposed at the upper end of the terminal block. Multiple clamping heads are fixedly connected to the lower end of the rectangular plate, and the lower ends of the clamping heads extend into the wiring slots. A conductive sheet is fixedly connected to the bottom of the wiring slots. An insertion slot is provided at the upper end of the terminal block. The rectangular plate and the upper end of the terminal block are elastically connected by multiple first springs. Vertical plates are fixedly connected to the left and right sides of the rectangular plate, and elastic sheets are fixedly connected to the opposite sides of the two vertical plates.
[0008] Preferably, the elastic sheet is inclined, and protrusions are provided on the opposite sides of the two elastic sheets.
[0009] Preferably, a fixing block is fixedly connected to both the left and right sides of the terminal block, and a pressing block is slidably connected through each of the two fixing blocks. The two pressing blocks are elastically connected to the fixing blocks by a second spring.
[0010] Preferably, a plurality of connecting blocks are fixedly connected to the front side of the terminal block, and a positioning cylinder is fixedly connected to the adjacent sides of every two cooperating connecting blocks, with each positioning cylinder located on the front side of the corresponding wiring slot.
[0011] Preferably, the front side of the housing is provided with multiple switches, and the front side of the housing is provided with multiple indicator lights arranged vertically.
[0012] Preferably, a fan is installed on the left side of the housing, and an air jet pipe is provided at the top of the inner side of each wiring slot. The upper end of each air jet pipe passes through a corresponding rectangular plate. Two rectangular plates are slidably connected to the air jet pipes. The air outlet of the fan is connected to a connecting pipe, and the upper ends of the multiple air jet pipes are connected to the connecting pipe.
[0013] Compared with existing technologies, the advantages of this device are:
[0014] 1. Compared with the existing technology, this device, by setting up a wire pressing assembly, uses multiple pressing heads at the lower end of the rectangular plate to cooperate with the conductive sheet at the bottom of the wiring slot, which can press the wires in each wiring slot at one time. This changes the inefficient operation method of traditional devices that require pressing the wires one by one, greatly improves the wiring efficiency, and at the same time ensures the firmness and stability of the electrical connection.
[0015] 2. Compared with the existing technology, this device does not require tools when releasing the wire clamping. Through the structural design of elastic sheet and squeezing block, the operator can complete the operation without direct contact with the terminal block, effectively avoiding the occurrence of electric shock and other safety accidents, and significantly improving the safety and convenience of operation.
[0016] 3. Compared with existing technologies, this device utilizes a heat dissipation structure composed of a fan, connecting pipe, and jet pipe. During use, it can use airflow to cool the wiring slot, dissipate the heat generated at the wiring points in a timely manner, effectively ensure the performance of the device, extend its service life, and solve the problem of insufficient heat dissipation in traditional devices.

[0021] 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.
[0022] Reference Figures 1-3An anti-power fluctuation device includes a housing 1 made of insulating and high-strength engineering plastic. The housing 1 is rectangular in shape, and its dimensions are designed according to the layout and installation requirements of the internal circuit board and other components, ensuring compact installation of internal components and providing adequate heat dissipation space. Multiple switches 4 are located on the front side of the housing 1, and multiple indicator lights are vertically arranged on the front side of the housing 1. From top to bottom, the indicator lights represent operation, closing, power fluctuation, and alarm, respectively. A circuit board is located inside the housing 1, and two terminal blocks 5 are fixedly connected to the front side of the housing 1. The two terminal blocks 5 are connected to the circuit board via wires. The connection is as follows: multiple wiring slots are provided on the front side of both terminal blocks 5, and a wire pressing assembly is provided on each terminal block 5. The wire pressing assembly includes a rectangular plate 8 set on the upper end of the terminal block 5, multiple pressing heads 10 are fixedly connected to the lower end of the rectangular plate 8, and the lower ends of the multiple pressing heads 10 extend into the wiring slot. A conductive sheet 9 is fixedly connected to the bottom of the wiring slot. An insertion slot is provided on the upper end of the terminal block 5. The rectangular plate 8 and the upper end of the terminal block 5 are elastically connected by multiple first springs 11. Vertical plates 13 are fixedly connected to the left and right sides of the rectangular plate 8, and elastic sheets 14 are fixedly connected to the opposite sides of the two vertical plates 13.
[0023] The elastic sheet 14 is inclined, and protrusions are provided on the opposite sides of the two elastic sheets 14. When the pressure head 10 does not press the wire, the protrusions are placed on the top of the terminal block 5. At this time, the first spring 11 is in a stretched state. After the elastic sheet 14 is deformed, the first spring 11 will cause the rectangular plate 8 to drive the pressure head 10 to move down and press the wire.
[0024] The terminal block 5 is fixedly connected to both the left and right sides with fixing blocks 15. Each fixing block 15 is slidably connected to a pressing block 16. The two pressing blocks 16 are elastically connected to the fixing blocks 15 by a second spring 17. The outer surface of the pressing block 16 is provided with anti-slip texture to facilitate pressing by the operator.
[0025] The front side of the terminal block 5 is fixedly connected to multiple connecting blocks 6. Each pair of cooperating connecting blocks 6 is fixedly connected to a positioning cylinder 7 on their adjacent sides. The positioning cylinder 7 is made of transparent polycarbonate material. Each positioning cylinder 7 is located on the front side of the corresponding wiring slot. Its inner diameter is adapted to the outer diameter of the wire, so as to guide the wire to be accurately inserted into the wiring slot.
[0026] The outer casing 1 has a fan 2 installed on the left side. Each wiring slot has an air jet pipe 12 at its top. The upper end of each air jet pipe 12 passes through a corresponding rectangular plate 8. The two rectangular plates 8 are slidably connected to the air jet pipe 12. The air outlet of the fan 2 is connected to a connecting pipe 3. The upper ends of the multiple air jet pipes 12 are connected to the connecting pipe 3.
[0027] The functional principle of this utility model can be explained through the following operation: During wiring, the wire is inserted into the wiring slot through the positioning cylinder 7. By pressing the pressing blocks 16 on both sides, the pressing blocks 16 push the elastic plates 14, causing the two elastic plates 14 to deform and move closer to the vertical plate 13. When the protrusions on the elastic plates 14 are not in contact with the upper end of the wiring plate 5, the rectangular plate 8, under the action of the first spring 11, drives the pressing head 10 to move downward, tightly pressing the wire between the pressing head 10 and the conductive plate 9, thereby achieving one-time pressing and fixing of all wires in the wiring slots, ensuring the stability and reliability of the electrical connection.
[0028] When it is necessary to release the wire clamping, simply pull up the rectangular plate 8. The rectangular plate 8 will cause the vertical plate 13 and the elastic plate 14 to rise simultaneously. After the protrusion disengages from the insertion slot, the elastic plate 14 will return to its original position and open to both sides under its own elasticity, allowing the protrusion to rest on the upper end of the terminal block 5 again. At this time, the rectangular plate 8 remains in the raised position, releasing the clamping of the wire. The entire process requires no tools and avoids direct contact between the operator's hands and the terminal block 5, ensuring operational safety.
[0029] During the operation of the device, the fan 2 installed on the left is started. The airflow generated by the fan 2 is delivered to each jet pipe 12 through the connecting pipe 3. The jet pipe 12 sprays the airflow into the wiring slot, using the airflow to carry away the heat generated in the wiring slot, thereby achieving the cooling and heat dissipation function, ensuring the stable performance of the device under long-term working conditions, and extending its service life.

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.
