Description

Technical Field

[0001] This utility model relates to the technical field of distribution boxes, and in particular to an anti-electric shock distribution box. Background Technology

[0002] A distribution box is an electrical device specifically designed for the distribution and control of electrical energy. Its core function is to safely and orderly distribute electrical energy from the power source to different circuits or electrical equipment.

[0003] Typically, a distribution box is a low-voltage power distribution device that integrates switching equipment such as circuit breakers and fuses, measuring instruments such as voltmeters and ammeters, protective electrical devices such as residual current devices (RCDs) and overload protectors, and auxiliary equipment within a closed or semi-closed metal cabinet or panel, forming a complete power distribution system. These distribution boxes are widely used inside buildings, such as homes, offices, and hospitals, and are generally suitable for low-voltage power distribution environments not exceeding 400V.

[0004] Based on this, Chinese patent CN106848884B discloses a power distribution box, which includes a main support frame inside the casing and multiple rectangular fixed frames mounted on the main support frame, as well as plug plates mounted on the fixed frames. The plug plates are equipped with contact sensors and wireless radio frequency readers. The contact sensors can detect whether a plug plate is inserted into the fixed frame, and the wireless radio frequency readers and transmitters can identify which plug plate is inserted into a specific fixed frame. Furthermore, when a trigger signal is received, the first wireless communication module can transmit the radio frequency signal from the wireless transmitter to the remote control terminal, and also transmit the contact sensor signal collected by the contact sensors to the remote control terminal. This allows the user to more clearly understand which plug plate is inserted into the fixed frame and whether a plug plate is inserted.

[0005] However, existing distribution boxes still present technical problems that can easily lead to electric shock accidents. Specifically, as the core equipment for power distribution, the design and management of the distribution box to prevent electric shock are directly related to personal safety and the stable operation of the power system. If a distribution box lacks leakage protection, has poor grounding, or lacks protection, it is highly susceptible to electric shock accidents. For example, aging wiring, damaged insulation, or live metal parts inside the distribution box may conduct current through contact with the cabinet surface or operating tools, creating an indirect risk of electric shock. In addition, overheating of equipment in high-temperature environments may accelerate the deterioration of insulation materials, further increasing the probability of electric shock. If traditional distribution boxes are not equipped with anti-accidental contact devices, operators may be electrocuted by accidentally touching live parts such as busbars or circuit breakers. Some distribution boxes also have increased opportunities for non-professionals to come into contact with live parts due to damaged or unclosed cabinet doors. Utility Model Content

[0028] Please refer to the following: Figures 1 to 4 The present invention relates to an anti-electric shock distribution box comprising: a box body 1, a cover 2, a rubber gasket 3, an electrical module 4, a circuit board unit 5, and an insulation isolation unit 6; the box body 1 and the cover 2 are configured to open and close relative to each other, and the rubber gasket 3 is provided between the box body 1 and the cover 2; the electrical module 4 is disposed in the box body 1 and connected to the circuit board unit 5; a plurality of insulation isolation units 6 are respectively connected to the circuit board unit 5 and the box body 1.

[0029] Specifically, in order to ensure the electromagnetic shielding performance of the electrical modules inside the distribution box and the structural protection performance of the distribution box, the box body 1 and the cover 2 are preferably made of metal. Therefore, when an operator touches the box body 1 or the cover 2 directly with their hands without protection, the box body 1 or the cover 2 may also become electrified due to factors such as aging of the wiring of the electrical module 4, insulation damage, or electrification of the metal parts, thus causing an electric shock accident.

[0030] Based on the foregoing reasons, this utility model proposes a dual-protection-against-electric shock distribution box. Firstly, the box body 1 and the cover 2 are insulated from each other by rubber gaskets 3, preventing electric shock when the user opens the cover 2 while the box body 1 is energized. Secondly, the energized electrical module 3 and the circuit board unit 5 are insulated from each other by insulating isolation units 6 evenly distributed within the box body 1, preventing current from entering the box body 1 from the electrical module 4 or the circuit board unit 5, thus avoiding electric shock when the user touches the box body 1. Therefore, this utility model's dual-protection-against-electric shock distribution box, through the aforementioned dual-protection-against-electric shock structure, fundamentally solves the problem of the box body 1 or the cover 2 becoming energized, ensuring that operators will not experience electric shock when opening the cover 2 to operate, maintain, or repair the interior of the box body 1. Therefore, this utility model's dual-protection-against-electric shock distribution box solves the technical problem of how to improve the insulation protection performance of a distribution box.

[0031] Furthermore, each of the aforementioned insulating isolation units 6 has an insulating support column 601, a positioning column 602, a first fastener 603, and a second fastener 604; the insulating support column 601 is disposed between the circuit board unit 5 and the housing 1, the positioning column 602 is disposed on the insulating support column 601, and the positioning column 602 is movably connected to the circuit board unit 5; the first fastener 603 connects the insulating support column 601 and the housing 1 respectively, and the second fastener 604 connects the positioning column 602 and the circuit board unit 5 respectively.

[0032] Specifically, the insulating support post 601 can be used to isolate the circuit board unit 5 from the enclosure 1, preventing current from flowing from the circuit board unit 5 to the enclosure 1. One embodiment is that the insulating support post 601 is made of polymer materials such as plastic, with its upper and lower ends connected to the positioning post 602 and the first fastener 603, respectively. Another embodiment is that the body of the insulating support post 601 is made of metal materials such as copper alloy or aluminum alloy, and its surface is uniformly coated with insulating paint. Of the two embodiments, the preferred technical solution is to use injection molding to make the insulating support post 601 from plastic. The positioning post 602 can be connected to the upper end of the insulating support post 601 by in-mold injection molding. The first fastener 603 can be a screw, bolt, or other connector; it can be inserted from the outside of the enclosure 1 and fix the insulating support post 601 to the inside of the enclosure 1. The second fastener 604 can be a nut or other connecting component. It can be threaded onto the positioning post 602 as the positioning post 602 protrudes from above the circuit board unit 5, thereby connecting the circuit board unit 5 to the insulating support post 601. By evenly distributing several sets of insulating support posts 601 within the housing 1, the circuit board unit 5 can be stably positioned within the housing 1.

[0033] Furthermore, the housing 1 has a receiving body 101, a wire groove 102, and an insulating limiting groove 103; the wire groove 102 is provided at the lower part of the receiving body 101, the insulating limiting groove 103 is provided on the side of the receiving body 101, the insulating limiting groove 103 is provided between the cover 2 and the housing 1, and the rubber spacer 3 is provided in the insulating limiting groove 103.

[0034] Furthermore, a rubber wire sleeve 7 is provided at the lower part of the housing 1, and the rubber wire sleeve 7 is movably disposed in the wire groove 102.

[0035] Specifically, the wire channel 102 is used to guide the wires inside the housing 1 to the outside. To prevent leakage to the housing 1 due to wire aging, a rubber wire sleeve 7 can be movably fitted inside the guide channel 102. The rubber wire sleeve 7 is an insulating sleeve made of rubber material, which can provide insulation around the wire channel 102. The insulating limiting groove 103 is used to accommodate the rubber spacer 3, which can also be made of rubber insulating material; it is used to provide insulation between the housing 1 and the cover 2.

[0036] Furthermore, the cover 2 has a cover plate body 201, a plurality of locking structures 202, and a sealing gasket 203; the cover plate body 201 and the receiving body 101 are respectively opened and closed relative to each other, and the plurality of locking structures 202 are evenly distributed in the cover plate body 201, and each cover plate body 201 is movably connected to the receiving body 101; the sealing gasket 203 is disposed on the side of the cover plate body 201, and the sealing gasket 203 is respectively connected to the cover plate body 201 and the receiving body 101.

[0037] Specifically, in order to isolate the possibility of electrical conductivity between the housing 1 and the cover 2, the cover body 101 and the accommodating body 101 are preferably not connected by a hinge. Instead, the cover body 201 can be directly covered and connected to the accommodating body 101. When the two are closed, a locking structure 202 is used to fix the connection between the two, preventing unauthorized personnel from opening the cover body 201. Instead, a designated key is required to open the locking structure 202, thereby separating the cover body 201 from the accommodating body 101. The sealing gasket 203 is disposed on the side of the cover body 201. When the cover body 201 covers and is connected to the receiving body 101, the sealing gasket 203 can cover and be connected to the insulating limiting groove 103, and its covering trajectory is different from the covering trajectory of the rubber spacer 3; or the sealing gasket 203 can be disposed on the rubber spacer 3. The preferred material of the sealing gasket 203 is foam, and its main function is to increase the sealing performance of the connection between the box 1 and the cover 2; however, since the lifespan of foam material is poor, the long-term insulation between the box 1 and the cover 2 is mainly provided by the rubber spacer 3.

[0038] Specifically, the electrical module 4 mainly includes circuit breakers, residual current devices (RCDs), instrument transformers, contactors, and surge protectors. Circuit breakers, also known as air switches, control the on / off state of the circuit under normal and fault conditions, providing both overload and short-circuit protection. For example, an air switch interrupts fault current through a thermomagnetic tripping mechanism. Residual current devices (RCDs) are typically used to detect current imbalances in the circuit, such as leakage current, and trigger tripping to protect personal safety; they are usually used in conjunction with circuit breakers. Instrument transformers typically include current transformers and voltage transformers; current transformers convert large currents into small current signals for instrument measurement or protection devices; voltage transformers are used for voltage signal conversion. Contactors are used for remote control of high-power equipment such as motors, driving contact opening and closing through electromagnetic coils. Surge protectors are used to prevent lightning strikes or overvoltage from impacting equipment.

[0039] In summary, this utility model provides an anti-electric shock distribution box comprising a box body 1, a cover 2, a rubber gasket 3, an electrical module 4, a circuit board unit 5, and an insulation isolation unit 6. The box body 1 and the cover 2 are configured to open and close relative to each other, with the rubber gasket 3 positioned between them. The electrical module 4 is housed within the box body 1 and connected to the circuit board unit 5. Several insulation isolation units 6 are respectively connected to the circuit board unit 5 and the box body 1. Through this dual anti-electric shock structure, this utility model's anti-electric shock distribution box fundamentally solves the problem of the box body 1 or the cover 2 becoming energized. Therefore, operators will not experience electric shock when opening the cover 2 to operate, maintain, or repair the interior of the box body 1. Thus, this utility model's anti-electric shock distribution box solves the technical problem of improving the insulation protection performance of distribution boxes.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
