Description

Technical Field

[0001] This invention relates to the field of power failure protection equipment, and more particularly to a power failure protection device for electronic information equipment. Background Technology

[0002] When electronic information equipment is in use, changes in circuit current and voltage can easily damage the equipment. Therefore, power-off protection devices need to be installed in the circuit. However, existing protection devices have a slow power-off process, which can cause electric arcs in the circuit. The contact point between the electric arc and the metal will generate high temperatures, which will corrode the metal. After repeated occurrences, the power-off protection device will be damaged, leaving the electronic information equipment to operate in an unprotected environment. Therefore, a new type of power-off protection device that can reduce the generation of electric arcs is needed.

[0003] For example, CN202310399649.4 proposes a power-off protection device for electronic information equipment, which includes a housing. Side plates are fixedly installed on both sides of the housing near the rear end. A switch mechanism is installed at the front end, and the switch mechanism and the connecting mechanism are connected by a linkage rod. When the switch mechanism is turned on, the connecting mechanism can be moved upward simultaneously. At this time, since the switch is turned on, the electromagnetic block is connected to the upper connecting block, and the temperature sensor is energized to detect the temperature. When the temperature is too high, the temperature sensor alarms the central control terminal and shuts off the electromagnetic block, causing the electromagnetic block to retract and move downward with the lower spring telescopic rod. Since the connecting mechanism and the switch mechanism are linked, the switch mechanism is turned down to cut off the power and the upward force of the switch mechanism is increased, improving safety. The switch mechanism can also be turned down manually. The two power-off methods give the device a good power-off protection function and prevent damage to electronic information equipment, but it does not solve the above-mentioned problems.

[0004] The present invention can extinguish the electric arc generated during power failure by means of an arc-extinguishing device, thus preventing damage to the power failure protection device. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are just examples and are not intended to limit the present invention.

[0031] The following describes a power failure protection device for electronic information equipment according to an embodiment of the present invention, with reference to the accompanying drawings. Figure 1 - Figure 8 As shown, the power failure protection device for electronic information equipment includes a first housing 1, on which an input terminal 2 and an output terminal 3 are provided, so that the power failure protection device can be connected to the circuit system of the electronic information equipment. It also includes an arc extinguishing device provided inside the first housing 1, which can extinguish the electric arc generated when the circuit is broken; a power failure device provided inside the first housing 1, which can quickly disconnect the circuit when the circuit current or voltage is abnormal, to prevent damage to the electronic information equipment; and a reset device provided on the top of the first housing 1, which is used to reset the power failure protection device for easy operation next time.

[0032] like Figure 3 , Figure 5 and Figure 7As shown, the power failure protection device for electronic information equipment includes an arc extinguishing device, which includes a first guide plate 4, an arc extinguishing assembly 5, a second housing 6, a contact plate 7, and a second guide plate 8. The first guide plate 4 is fixed to the outside of the input terminal 2, the arc extinguishing assembly 5 is fixed inside the first housing 1, the second housing 6 is located inside the first housing 1, the contact plate 7 is fixed to both sides of one end of the second housing 6, and the second guide plate 8 is fixed to the outside of the contact plate 7. The first guide plate 4 is obliquely arranged and forms an angle with the contact plate 7. The arc extinguishing assembly 5 is provided with insulating plates for fixed installation at the top and bottom, and multiple metal plates are provided between the upper and lower insulating plates. The front end of the metal plates has a "V"-shaped opening, and the metal plates fit the oblique arrangement of the first guide plate 4. The first guide plate 4 and the second guide plate 8 are made of corrosion-resistant conductive metal.

[0033] In a specific embodiment: During use, the contact piece 7 is in contact with the input terminal 2 to conduct electricity, thereby enabling the electronic information device to connect the circuit and operate. When the power is off, the contact piece 7 is disconnected from the input terminal 2. If an electric arc is generated between the contact piece 7 and the input terminal 2, as the input terminal 2 moves, the electric arc will be generated at one end from the second guide piece 8 due to the tip discharge effect, and the other end of the electric arc will first be generated from the input terminal 2. Then, as the electric arc moves, it will move to the first guide piece 4. When the electric arc moves between the first guide piece 4 and the second guide piece 8, it will pass through the arc extinguishing component 5. Through the "V"-shaped opening of the multiple metal plates on the arc extinguishing component 5, the electric arc is guided to the arc extinguishing component 5. Then, the multiple metal plates divide and isolate the electric arc, thereby dispersing and extinguishing the electric arc.

[0034] like Figure 6 , Figure 7 and Figure 8 As shown, the power-off protection device for electronic information equipment includes a power-off device, which comprises a frame 9, a first iron core 11, a second iron core 13, a bimetallic strip 15, a first buckle 16, a slide 17, and a button 25. The frame 9 is installed in the second housing 6, and an electromagnetic winding 10 is provided on the outside of the frame 9. The first iron core 11 and the second iron core 13 are installed inside the frame 9. The bimetallic strip 15 is fixed to the second housing 6, the first buckle 16 is fixed to the first housing 1, and the slide 17 is slidably installed inside the first housing 1. The slide 17 and the first housing 1 are connected... A spring is provided between the slide 17 and the second outer shell 6. The button 25 is slidably disposed on the first outer shell 1. A spring is provided between the button 25 and the first outer shell 1. A spring is provided between the first iron core 11 and the frame 9. The end of the first iron core 11 is fixed to the slide 17. A spring is provided between the second iron core 13 and the second outer shell 6. A push plate 14 is provided at the end of the second iron core 13. The bimetallic strip 15 is made of two conductive metals with different heat deformation rates bonded together. A through hole corresponding to the position of the first buckle 16 is opened on the bimetallic strip 15.

[0035] In a specific embodiment: during use, one end of the electromagnetic winding 10 is connected to the live wire (connected to the live wire) on one side through a wire, and the other end is connected to one end of the bimetallic strip 15. The other end of the bimetallic strip 15 is connected to the output terminal 3, and the live wire (connected to the neutral wire) on the other side is connected to the output terminal 3 through a wire, thereby forming an energized circuit, thereby generating magnetic force in the electromagnetic winding 10, so that the first iron core 11 and the second iron core 13 remain stable in the frame 9.

[0036] When a short circuit occurs, the current in the circuit increases instantaneously, causing the electromagnetic winding 10 to push the first iron core 11 and the second iron core 13 to move. This causes the first iron core 11 to pull the slide 17 and further stretch the corresponding spring, while the second iron core 13 pushes the push plate 14. The push plate 14 then engages between the bimetallic strip 15 and the first latch 16, causing the first latch 16 to deform and disengage from the bimetallic strip 15. Under the action of the spring below the slide 17, the slide 17 and the second outer shell 6 move downwards, causing the contact piece 7 to disengage from the input terminal 2, thus disconnecting the circuit and protecting it.

[0037] When the circuit is overloaded, the voltage in the circuit gradually increases, causing the current to gradually increase. The bimetallic strip 15 begins to heat up. Since the bimetallic strip 15 is made of two conductive metals with different thermal deformation rates bonded together, the bimetallic strip 15 bends upward, thereby causing the bimetallic strip 15 to disengage from the first buckle 16. Under the action of the spring below the slide 17, the slide 17 and the second housing 6 move downward, thereby causing the contact piece 7 to disengage from the input terminal 2, disconnecting the circuit and protecting the circuit.

[0038] When the power is manually cut off, pressing button 25 causes the first latch 16 to deform and disengage from the bimetallic strip 15. This causes the slide 17 and the second housing 6 to move downward under the action of the spring below the slide 17, thereby causing the contact piece 7 to disengage from the input terminal 2 and disconnecting the circuit.

[0039] like Figure 6 As shown, the power failure protection device for electronic information equipment includes a reset device. The reset device includes a limit frame 19, a second buckle 20, a first handle 21, a second handle 22, and a locking plate 24. The limit frame 19 is fixed to the second housing 6. The second buckle 20 is rotatably installed on both sides of the second housing 6. The first handle 21 is fixed to the second housing 6. The second handle 22 is slidably installed on the first handle 21. A spring is provided between the second handle 22 and the first handle 21. The locking plate 24 is fixed inside the first housing 1. The locking plate 24 has a through hole corresponding to the second buckle 20. The rear end of the second buckle 20 has a slope. A torsion spring is provided between the second buckle 20 and the second housing 6. The lower end of the second handle 22 has a slope.

[0040] In a specific embodiment: when the power is off, the second outer shell 6 moves down, and the second latch 20 hooks onto the latch plate 24, thereby preventing the second outer shell 6 from rebounding and making the power off more thorough.

[0041] During reset, by pressing down the second handle 22, the second handle 22 pushes the second buckle 20 to rotate, thereby disengaging from the card plate 24. Then, by pushing the second outer shell 6 through the first handle 21 and the second handle 22, the first buckle 16 hooks the bimetallic strip 15, and the contact piece 7 contacts the input terminal 2 to conduct electricity.

[0042] Working principle: During use, the contact piece 7 makes contact with the input terminal 2, thus connecting the electronic information equipment to operate. When a short circuit occurs, the current in the circuit increases instantaneously, causing the electromagnetic winding 10 to push the first iron core 11 and the second iron core 13 to move. This causes the first iron core 11 to pull the slide 17 and further stretch the corresponding spring, while the second iron core 13 pushes the push plate 14. The push plate 14 then engages between the bimetallic strip 15 and the first latch 16, causing the first latch 16 to deform and disengage from the bimetallic strip 15. Under the action of the spring below the slide 17, the slide 17 and the second outer shell 6 move downwards, causing the contact piece 7 to disengage from the input terminal 2, disconnecting the circuit and protecting it. When an overload occurs, the voltage in the circuit... As the current gradually increases, the bimetallic strip 15 begins to heat up. Because the bimetallic strip 15 is made of two conductive metals with different heat deformation rates bonded together, it bends upward, causing the bimetallic strip 15 to disengage from the first latch 16. Under the action of the spring below the slide 17, the slide 17 and the second housing 6 move downward, causing the contact piece 7 to disengage from the input terminal 2, thus disconnecting the circuit and protecting it. During reset, pressing down the second handle 22 causes the second handle 22 to push the second latch 20 to rotate, thereby disengaging it from the latch plate 24. Then, the first handle 21 and the second handle 22 push the second housing 6, causing the first latch 16 to hook the bimetallic strip 15 and making the contact piece 7 contact the input terminal 2 to conduct electricity.
