Description

Technical Field

[0001] This invention relates to the field of advanced non-ferrous metal materials, and more specifically to the field of power plugs, and more particularly to a power plug with an integrated overheat protection system. Background Technology

[0002] An integrated overheat protection power plug is an electrical connector that integrates temperature monitoring and circuit on / off control functions into a traditional power plug. Its core function is to monitor the operating temperature of the plug and connected appliances in real time through a built-in overheat protection mechanism. When the temperature exceeds the preset safety range, it quickly cuts off the current output, thereby preventing safety risks such as aging of the circuit, short circuit or even fire caused by overheating, and providing active protection for electrical safety.

[0003] In addition to the power transmission function of conventional plugs, these power plugs also have three core protection functions: First, they can accurately measure temperature by collecting temperature data of the plug shell, pin contacts and connected wires in real time through temperature sensors or temperature sensing elements. Second, they have a threshold judgment function, which compares the measured temperature with a preset safety threshold to determine whether there is a risk of overheating. Third, they have a quick power-off function, which triggers the actuator to cut off the main circuit when the temperature is confirmed to be above the limit, preventing heat from accumulating.

[0004] However, in actual use, although the existing technology performs reasonably well in terms of the immediacy of overheat protection, when the plug is de-energized due to overheating, even if the temperature drops to a safe range, it is difficult to automatically restore power. It still requires manual pressing of the reset button to close the plug again. In actual use, such as refrigerators and aquarium oxygenation equipment that operate at night, if they cannot automatically restore power after a brief overheating power outage, it may lead to food spoilage and oxygen deficiency in the organisms. For unattended industrial control equipment, a sudden shutdown may cause production process interruption and economic losses. Summary of the Invention

[0005] This invention proposes a power plug with an integrated overheat protection system to solve the problem mentioned in the background art. In actual operation, when the power plug with an integrated overheat protection system is cut off due to overheating, it is difficult to automatically restore power supply.

[0007] The electrical connector is installed inside the power supply enclosure;

[0008] The power pole assembly has three members and a circuit breaking function. The power pole assembly is triangularly arranged inside the power supply enclosure. The power transmission line is electrically connected to the electrical connector and the power pole assembly through the power supply enclosure.

[0009] The pneumatic circuit breaker assembly is disposed inside the power supply enclosure. The pneumatic circuit breaker assembly is connected to the plug-in pole group and can disconnect the plug-in pole group.

[0010] The physical temperature control adjustment component is installed inside the power supply enclosure. The physical temperature control adjustment component is connected to the pneumatic circuit breaker component and can self-lock the pneumatic circuit breaker component in the event of a high-temperature power outage.

[0011] As a preferred technical solution of the present invention, the plug-in pole assembly includes a conductive plug and a power connection post;

[0012] The conductive plug is disposed through and sealed within the power supply housing.

[0013] The power contact post is disposed inside the power supply enclosure and above the conductive plug, and can be electrically connected to the power transmission line. A conductive break section is provided between the power contact post and the conductive plug.

[0014] Furthermore, based on the aforementioned solution, the conductive circuit breaker includes a circuit breaker cylinder, a hexagonal circuit breaker rod, and an air extraction pipe;

[0015] The circuit breaker cylinder is mounted on the conductive plug;

[0016] The hexagonal circuit breaker rod passes through and slides on one end of the circuit breaker cylinder near the power receiving post. A push-in spring is provided between the hexagonal circuit breaker rod and the circuit breaker cylinder. A hexagonal groove adapted to the hexagonal circuit breaker rod is provided on the conductive plug rod.

[0017] One end of the extraction pipe is connected to one side of the circuit breaker cylinder.

[0018] As a preferred technical solution of the present invention, the pneumatic circuit breaker assembly includes a circuit breaker suction box, a convex suction plug, and an electromagnetic positioning part;

[0019] The circuit breaker extraction box is installed inside the power supply enclosure;

[0020] The convex suction plug is slidably disposed inside the circuit breaker suction box, and the convex suction plug divides the circuit breaker suction box into a positioning chamber and a suction chamber. The other end of the suction pipe is connected to the suction chamber.

[0021] The electromagnetic positioning part is disposed on the convex suction plug, which can adjust the position of the convex suction plug.

[0022] Furthermore, based on the aforementioned scheme, the electromagnetic positioning part includes an upper electromagnet and a lower electromagnet;

[0023] The upper electromagnet is disposed inside the power supply housing and is located above the convex suction plug;

[0024] The lower electromagnet is mounted on the convex suction plug, and a circuit-breaking adjustment cavity is formed between the lower electromagnet and the upper electromagnet.

[0025] As a preferred technical solution of the present invention, the physical temperature control adjustment component includes a temperature control expansion adjustment part and a high temperature self-locking part;

[0026] The temperature-controlled expansion adjustment part is located inside the power supply housing;

[0027] The high-temperature self-locking part is disposed inside the power supply enclosure and is connected to the temperature-controlled expansion adjustment part. A self-locking pipeline is connected between the high-temperature self-locking part and the positioning cavity.

[0028] Furthermore, based on the aforementioned solution, the temperature-controlled expansion adjustment unit includes a temperature control box and an expansion adjustment plug;

[0029] The temperature control box is housed inside the power supply enclosure, and the temperature control box is filled with expanding gas.

[0030] The expansion adjustment plug is installed through and in a sealed sliding configuration inside the temperature control box.

[0031] Furthermore, based on the aforementioned scheme, the high-temperature self-locking part includes a self-locking positioning cylinder and a self-locking plunger;

[0032] The self-locking positioning cylinder is disposed inside the power supply enclosure;

[0033] The self-locking plunger is slidably disposed inside the self-locking positioning cylinder and is sealed. An adjustment rod is provided between the self-locking plunger and the expansion adjustment plug. When the self-locking plunger moves inside the self-locking positioning cylinder, it can form a vacuum cavity. One end of the self-locking pipeline is connected to the vacuum cavity.

[0034] Based on the aforementioned scheme, cooling components are also provided on both sides of the power supply cover. The cooling components include a cooling air supply box, a cooling fan, and a dust filter.

[0035] Two cooling gas boxes are provided and are symmetrically connected on the power supply cover;

[0036] The cooling fan is installed inside one of the cooling air supply boxes;

[0037] The dust filter is installed inside another cooling gas box.

[0038] The beneficial effects of this invention are as follows:

[0039] 1. In this invention, by setting electrical connectors and power transmission components, the upper and lower electromagnets are electrically connected to the electrical connectors. The direction of the magnetic poles of the upper and lower electromagnets is controlled by the electrical connectors, causing them to repel each other. During the charging process of the power plug, by setting plug rod assembly and pneumatic circuit breaker assembly, when the temperature inside the power supply housing is too high and reaches the preset value of the electrical connectors, the direction of the magnetic poles of the upper and lower electromagnets is controlled by the electrical connectors, causing the upper and lower electromagnets to attract each other. The lower electromagnet moves towards the upper electromagnet, and the movement of the lower electromagnet drives the movement of the convex suction plug in the circuit breaker suction box. The convex suction plug squeezes the positioning cavity and expands the suction cavity. The air pressure in the suction cavity decreases, and the gas in the circuit breaker cylinder enters the suction cavity along the suction pipe. Under the action of air pressure, the hexagonal circuit breaker rod squeezes the push spring and moves into the circuit breaker cylinder, causing the hexagonal circuit breaker rod to separate from the hexagonal slot, thereby achieving the circuit breaking effect.

[0040] 2. In this invention, by setting a physical temperature control adjustment component, as the temperature inside the power supply enclosure increases, the expanding gas gradually expands. By increasing the gas pressure inside the temperature control box, the expansion adjustment plug moves away from the temperature control box. The movement of the expansion adjustment plug can drive the adjustment rod and the self-locking plunger to move. Through the movement of the self-locking plunger, the gas in the positioning cavity can enter the vacuum cavity through the self-locking pipe network. After the hexagonal circuit breaker rod separates from the hexagonal slot, the power plug will be in a de-energized state. In the de-energized state, both the upper and lower electromagnets lose their magnetism. The position of the convex suction plug can be temporarily fixed by the pressure of the positioning cavity extracted by the vacuum cavity. As the temperature inside the power supply enclosure decreases, the volume of the expanding gas inside the temperature control box contracts, and the expansion adjustment plug moves towards the temperature control box, causing the gas in the vacuum cavity to return to the positioning cavity. Through the rebound of the push spring, the gas in the suction cavity enters the circuit breaker cylinder, resetting the convex suction plug and causing the hexagonal circuit breaker rod to enter the hexagonal slot, thereby restoring the power supply state.

[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figures 1 to 8 As shown, this embodiment belongs to the field of advanced non-ferrous metal materials and proposes a power plug with an integrated overheat protection system, including an electrical connector 001 and a power transmission line 002, as well as a power cover 1, a plug pole assembly 003, a pneumatic circuit breaker assembly 004 and a physical temperature control adjustment assembly 005. The electrical connector 001 is installed inside the power cover 1.

[0054] The electrical connector 001 and the power transmission line 002 mentioned above are commonly used parts in power plugs that integrate overheat protection systems in the prior art. Their specific structures are not the main innovation of this invention and will not be described in detail here.

[0055] As mentioned above, there are three plug pole groups 003, which have a circuit breaking function. The plug pole groups 003 are triangularly arranged inside the power supply cover 1. The three plug pole groups 003 are used for connecting the neutral wire, the live wire and the ground wire respectively. The power transmission line 002 is electrically connected to the electrical connector 001 and the plug pole groups 003 through the power supply cover 1.

[0056] The plug-in assembly 003 includes a conductive plug 2 and a terminal block 3. The conductive plug 2 is installed inside the power supply housing 1 and sealed. The terminal block 3 is installed inside the power supply housing 1 and located above the conductive plug 2, and can be electrically connected to the power transmission line 002. A conductive circuit breaker is provided between the terminal block 3 and the conductive plug 2. The conductive circuit breaker includes a circuit breaker cylinder 4, a hexagonal circuit breaker rod 5, and a vacuum pipe 7. The circuit breaker cylinder 4 is installed on the conductive plug 2. The hexagonal circuit breaker rod 5 is installed through and slidably installed at one end of the circuit breaker cylinder 4 near the terminal block 3. A push-in spring 6 is provided between the hexagonal circuit breaker rod 5 and the circuit breaker cylinder 4. A hexagonal groove adapted to the hexagonal circuit breaker rod 5 is opened on the conductive plug 2. One end of the vacuum pipe 7 is connected to one side of the circuit breaker cylinder 4.

[0057] Specifically, by setting the jacking spring 6, the hexagonal circuit breaker rod 5 can be tightly fitted into the hexagonal slot, achieving stable power transmission. By setting the air extraction pipe 7, when the gas in the circuit breaker cylinder 4 is extracted through the air extraction pipe 7, the air pressure in the circuit breaker cylinder 4 decreases, and the hexagonal circuit breaker rod 5 will move into the circuit breaker cylinder 4, realizing the separation operation of the hexagonal circuit breaker rod 5 from the hexagonal slot.

[0058] The pneumatic circuit breaker assembly 004 described above is installed inside the power supply enclosure 1. The pneumatic circuit breaker assembly 004 is connected to the plug rod assembly 003 and can disconnect the plug rod assembly 003. The pneumatic circuit breaker assembly 004 includes a circuit breaker suction box 8, a convex suction plug 9, and an electromagnetic positioning part. The circuit breaker suction box 8 is installed inside the power supply enclosure 1. The convex suction plug 9 is installed inside the circuit breaker suction box 8 and is sealed and slidably installed inside the circuit breaker suction box 8. The convex suction plug 9 divides the circuit breaker suction box 8 into a positioning chamber 10 and a suction chamber 11. The other end of the suction pipe 7 is connected to the suction chamber 11. The electromagnetic positioning part is installed on the convex suction plug 9 and can adjust the position of the convex suction plug 9.

[0059] The electromagnetic positioning unit includes an upper electromagnet 12 and a lower electromagnet 13. The upper electromagnet 12 is installed inside the power supply housing 1 and is located above the convex suction plug 9. The lower electromagnet 13 is installed on the convex suction plug 9. A circuit-breaking adjustment cavity is formed between the lower electromagnet 13 and the upper electromagnet 12.

[0060] Both the upper electromagnet 12 and the lower electromagnet 13 are electrically connected to the electrical connector 001. The electrical connector 001 controls the opening and closing of the upper electromagnet 12 and the direction of their magnetic poles. During charging, when the temperature inside the power supply housing 1 reaches a preset value set by the electrical connector 001, the electrical connector 001 controls the direction of the magnetic poles of the upper electromagnet 12 and the lower electromagnet 13, causing the upper electromagnet 12 to attract the lower electromagnet 13, and the lower electromagnet 13 to move towards the lower pole. The movement of the upper electromagnet 12, through the movement of the lower electromagnet 13, drives the movement of the convex suction plug 9 within the circuit-breaking suction box 8, causing the convex suction plug 9 to squeeze the positioning cavity 10 and simultaneously expand the suction cavity 11. The air pressure in the suction cavity 11 decreases, and the gas in the circuit-breaking cylinder 4 enters the suction cavity 11 along the suction pipe 7. Under the action of air pressure, the hexagonal circuit-breaking rod 5 squeezes the push spring 6 and moves towards the circuit-breaking cylinder 4, causing the hexagonal circuit-breaking rod 5 to separate from the hexagonal groove, thereby achieving the circuit-breaking effect.

[0061] The aforementioned physical temperature control adjustment component 005 is installed inside the power supply enclosure 1. The physical temperature control adjustment component 005 is connected to the pneumatic circuit breaker component 004 and can self-lock the pneumatic circuit breaker component 004 in the event of a high-temperature power outage. The physical temperature control adjustment component 005 includes a temperature control expansion adjustment part and a high-temperature self-locking part. The temperature control expansion adjustment part is installed inside the power supply enclosure 1, and the high-temperature self-locking part is installed inside the power supply enclosure 1 and connected to the temperature control expansion adjustment part. A self-locking pipe network 14 is connected between the high-temperature self-locking part and the positioning cavity 10.

[0062] The temperature control expansion adjustment unit includes a temperature control box 15 and an expansion adjustment plug 16. The temperature control box 15 is installed inside the power supply cover 1 and is filled with expansion gas. The expansion adjustment plug 16 is installed inside the temperature control box 15 in a sealed manner.

[0063] The high-temperature self-locking part includes a self-locking positioning cylinder 17 and a self-locking plunger 18. The self-locking positioning cylinder 17 is installed inside the power supply cover 1. The self-locking plunger 18 is slidably installed inside the self-locking positioning cylinder 17 with sealing. An adjusting rod 19 is provided between the self-locking plunger 18 and the expansion adjusting plug 16. When the self-locking plunger 18 moves inside the self-locking positioning cylinder 17, it can form a vacuum chamber. One end of the self-locking pipeline 14 is connected to the vacuum chamber.

[0064] Specifically, by setting up the physical temperature control adjustment component 005, as the temperature inside the power supply enclosure 1 increases, the expanding gas gradually expands, increasing the gas pressure inside the temperature control box 15. This causes the expansion adjustment plug 16 to move away from the temperature control box 15. The movement of the expansion adjustment plug 16 drives the adjustment rod 19 and the self-locking plunger 18 to move. Through the movement of the self-locking plunger 18, the gas in the positioning cavity 10 can enter the vacuum cavity through the self-locking pipe network 14. After the hexagonal circuit breaker 5 separates from the hexagonal slot, the power plug will be in a power-off state. When both the upper electromagnet 12 and the lower electromagnet 13 lose their magnetism, the position of the convex suction plug 9 can be temporarily fixed by drawing pressure from the positioning cavity 10 through the vacuum chamber. As the temperature inside the power supply enclosure 1 decreases, the volume of the expanding gas in the temperature control box 15 contracts, and the expansion adjustment plug 16 moves into the temperature control box 15, causing the gas in the vacuum chamber to return to the positioning cavity 10. Through the rebound of the push spring 6, the gas in the suction chamber 11 enters the circuit breaker cylinder 4, resetting the convex suction plug 9 and causing the hexagonal circuit breaker rod 5 to enter the hexagonal slot, thereby restoring the power supply state.

[0065] It should be noted that cooling components are also provided on both sides of the power supply cover 1. The cooling components include a cooling air supply box 20, a cooling fan 21, and a dust filter 22. There are two cooling air supply boxes 20, which are symmetrically connected on the power supply cover 1. The cooling fan 21 is installed in one of the cooling air supply boxes 20, and the dust filter 22 is installed in the other cooling air supply box 20.

[0066] The cooling fan 21 is electrically connected to the electrical connector 001. The speed of the cooling fan 21 can be controlled by the electrical connector 001, so that the outside air can enter the power supply cover 1 through the dust filter 22 to cool the power supply cover 1.

[0067] To further clarify, the electrical connector 001 is a component that can collect real-time temperature data changes of the power supply housing 1, the plug-in rod assembly 003, and the plug-in component through a temperature sensor or temperature sensing element, and simultaneously adjust the speed of the cooling fan 21, the opening and closing of the upper electromagnet 12 and the lower electromagnet 13, and their magnetic poles.

[0068] In normal power supply mode, the magnetic poles of the upper electromagnet 12 and the lower electromagnet 13 are in a state of mutual repulsion. In this state, even if the temperature control box 15 is heated and the expanding gas expands, causing the expansion adjustment plug 16 to move, only part of the gas in the positioning cavity 10 can be drawn into the self-locking cavity. Under the action of magnetic pole repulsion, the convex suction plug 9 can be fixed in the circuit-breaking suction box 8, and the position of the convex suction plug 9 will not change.

[0069] The specific power supply process is as follows:

[0070] 1. Initial connection state: The three plug rods 003 of the power plug (corresponding to the neutral wire, live wire and ground wire respectively) are inserted into the socket. The conductive plug rod 2 achieves circuit connection through the tight fit between the hexagonal circuit breaker rod 5 and the hexagonal slot. The push-in spring 6 provides elasticity to keep the hexagonal circuit breaker rod 5 in contact with the hexagonal slot, ensuring stable power transmission.

[0071] II. Power transmission path: Current enters from the conductive plug 2 of the plug pole group 003, passes through the circuit breaker 4, the hexagonal circuit breaker 5, and the terminal block 3 to the electrical connector 001, and is then transmitted to the electrical equipment through the power transmission line 002 to complete normal power supply.

[0072] III. Temperature monitoring and basic cooling: Electrical connector 001 monitors the temperature of key components such as power supply enclosure 1 and plug pole assembly 003 in real time through built-in temperature sensors. Within the normal temperature range, cooling fan 21 operates at an appropriate speed according to preset program or real-time temperature. Outside cold air enters power supply enclosure 1 after being filtered by dust filter 22, and forms airflow circulation through cooling air box 20 to maintain the normal operating temperature of the equipment.

[0073] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
