[0001] This utility model belongs to the field of power distribution cabinet heating technology, specifically relating to a heating plate installation structure. Background Technology

[0002] In the field of power distribution cabinet applications, in order to prevent water vapor condensation inside the cabinet due to changes in ambient temperature or high air humidity, which could lead to serious problems such as electrical short circuits, corrosion of metal parts, and deterioration of insulation performance, heating plates are usually installed inside the cabinet.

[0003] In existing technologies, heating plates are typically fixed to the mounting base by welding. This welding installation method has obvious drawbacks: the high temperature generated during the welding process can easily lead to thermal deformation of the components and internal stress concentration, affecting the reliability of long-term use; and when the heating plate needs to be replaced or maintained, it is necessary to use special tools to break the weld points for disassembly, which is cumbersome and has high maintenance costs.

[0004] In view of the shortcomings of the above-mentioned welding installation method, this utility model attempts to overcome the inherent drawbacks of welding fixation by adopting an installation structure with mechanical stamping and pressing connection. Utility Model Content

[0005] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a heating plate mounting structure with the advantage of easy assembly and disassembly.

[0006] To achieve the above objectives, this utility model provides a heating plate mounting structure, comprising:

[0008] A fastening plate of the same size as the protective shell, with a side groove on the front, into which the side of the protective shell can be inserted;

[0009] A T-shaped plate is provided on the back of the fastening plate. The T-shaped plate can be inserted into a socket of the same size as the T-shaped plate that is fixed to the inner wall of the distribution box.

[0010] As a further improvement of this utility model, the T-shaped plate has a thick plate in the middle, and the thick plate is fixedly connected to the back of the fastening plate so that there is a gap between the two sides of the T-shaped plate and the back of the fastening plate; the insert has a channel in the middle for the thick plate to pass through, and the two sides of the insert can be inserted into the T-shaped plate; a baffle is provided at the bottom of the insert to prevent the T-shaped plate from sliding out.

[0011] As a further improvement of this utility model, the insert is made of stainless steel, and a magnetic strip is provided on the top of the T-shaped plate.

[0012] As a further improvement of this utility model, the two sides of the T-shaped plate are interference-fitted with the two sides of the insert sleeve.

[0013] As a further improvement of this utility model, both the outer surface of the T-shaped plate and the inner surface of the insert are sanded.

[0014] As a further improvement of this utility model, the back of the protective shell has a receiving cavity of the same size as the heating plate, and a sealing ring is provided at the edge of the receiving cavity.

[0015] As a further improvement of this utility model, an aviation socket is provided at the edge of the heating plate, and a socket placement groove is provided at the corresponding position on the back edge of the protective shell. When the heating plate is placed into the receiving cavity, the aviation socket can be placed into the socket placement groove.

[0017] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0018] This utility model discloses a heating plate mounting structure that simplifies the assembly process of the heating plate module and enables easy installation through a mechanical connection method involving side slot insertion and stamping between the protective shell and the fastening plate. The interference fit structure between the T-shaped plate and the socket, combined with bottom baffle limiting and magnetic assisted positioning, significantly enhances the overall stability and vibration resistance after installation. The sealing ring on the edge of the receiving cavity on the back of the protective shell effectively improves moisture-proof sealing performance, while the heat dissipation ribs distributed on the front significantly improve heat dissipation efficiency. The design of integrating an aviation socket on the edge of the heating plate and aligning it with the socket placement slot on the protective shell makes electrical connection more convenient and reliable, avoiding wiring interference. Compared to a completely welded method, the overall structure is easier to assemble and disassemble, greatly improving installation and maintenance efficiency while ensuring connection strength and heat dissipation effect.

[0028] 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.

[0029] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The terms “comprising,” “including,” etc., as used herein indicate the presence of the stated features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0030] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein are to be interpreted in a manner consistent with the context of this specification, and not in an idealized or overly rigid way. Example

[0031] Depend on Figure 1-4 This invention provides a heating plate mounting structure, mainly used in electrical distribution cabinets, to provide anti-condensation heating for electrical equipment. This structure aims to achieve rapid installation, disassembly, and stable fixation of the heating plate.

[0032] The heating plate mounting structure mainly includes a protective shell 1, a heating plate 2, a fastening plate 3, a T-shaped plate 4, and a socket 5.

[0033] The protective shell 1 is used to house and protect the internal heating plate 2. The back of the protective shell 1 has a cavity 15 that matches the dimensions of the heating plate 2, allowing the heating plate 2 to be placed horizontally within the cavity 15. To protect the heating plate 2 from moisture and improve heat conduction, a sealing ring 12 is provided at the edge of the cavity 15. The front of the protective shell 1 has multiple heat dissipation ribs 14 to increase the heat dissipation area and improve heating efficiency and convection.

[0034] The heating plate 2 serves as a heat source, and an aviation socket 21 is provided at its edge. Correspondingly, a socket placement slot 13 is provided on the edge of the back of the protective shell 1. When the heating plate 2 is correctly placed into the receiving cavity 15, the aviation socket 21 fits perfectly into the socket placement slot 13. This design not only provides protective space for the socket, avoiding squeezing during installation, but also makes the insertion and removal of power connectors (such as aviation plugs) more convenient.

[0035] The fastening plate 3 is used to fix the entire protective shell assembly to the inner wall of the distribution cabinet. The fastening plate 3 has the same dimensions as the protective shell 1, and its front side has a side groove 31. During installation, the side 11 of the protective shell 1 is inserted along the side groove 31 and mechanically pressed to achieve a quick and precise snap-fit ​​between the protective shell 1 and the fastening plate 3. This design makes it easier to disassemble and assemble the heating plate 2 than welding; during disassembly, the heating plate 2 can be removed simply by opening the stamping part.

[0036] The T-shaped plate 4 is fixedly connected to the back of the fastening plate 3 by welding or screws, and is a key component for connecting to the distribution cabinet. The middle of the T-shaped plate 4 is a thick plate 41, which is fixedly connected to the back of the fastening plate 3, creating a certain gap between the two side wings of the T-shaped plate 4 and the back of the fastening plate 3. A magnetic strip 42 is also attached to the top of the T-shaped plate 4 to provide suction force and assist in positioning during the initial installation phase.

[0037] The insert 5 is pre-installed on the inner wall of the distribution cabinet by welding or screw fixing. The internal shape of the insert 5 matches the T-shaped plate 4, and a channel 51 is provided in the middle to allow the thick plate 41 in the middle of the T-shaped plate 4 to pass through. The two sides of the channel 51 are grooves to accommodate the side wings of the T-shaped plate 4. A baffle 52 is provided at the bottom of the insert 5 to prevent the T-shaped plate 4 from slipping out due to gravity or vibration after insertion.

[0038] Working principle: First, the plug sleeve 5 is pre-fixed to the inner wall of the distribution cabinet. During installation, the side 11 of the protective shell 1 with the heating plate 2 is horizontally pushed into the side groove 31 of the fastening plate 3 and mechanically pressed to ensure that the protective shell 1 will not detach from the fastening plate 3. Then, the assembled whole is vertically pressed down so that the T-shaped plate 4 on the back of the fastening plate 3 is aligned and inserted into the plug sleeve 5. At this time, the thick plate 41 in the middle of the T-shaped plate 4 passes through the channel 51 of the plug sleeve 5, and the two wings slide in along the inner track of the plug sleeve 5. Finally, the bottom baffle 52 achieves mechanical limitation, and the magnetic attraction of the magnetic strip 42 enhances the connection stability, thereby completing the firm installation of the entire heating plate module. Example

[0039] The difference between this embodiment and Embodiment 1 is that the two sides of the T-shaped plate 4 and the insert 5 are not fixed by magnetic attraction, but by the friction between them. The two sides of the T-shaped plate 4 and the two sides of the insert 5 are interference fit. To further increase the friction, the outer surface of the T-shaped plate 4 and the inner surface of the insert 5 can be sanded (not shown in the figure).

[0040] This design further enhances the stability after installation, making it less likely for the T-shaped plate 4 and the sleeve 5 to separate.

[0041] In summary, this utility model's heating plate mounting structure significantly simplifies the assembly process of the heating plate module and achieves easy installation through a mechanical connection method involving side slot insertion and stamping between the protective shell and the fastening plate. The interference fit structure between the T-shaped plate and the socket, combined with bottom baffle limiting and magnetic assisted positioning, significantly enhances the overall stability and vibration resistance after installation. The sealing ring on the edge of the receiving cavity on the back of the protective shell effectively improves moisture-proof sealing performance, while the heat dissipation ribs distributed on the front significantly improve heat dissipation efficiency. The design of integrating an aviation socket on the edge of the heating plate and aligning it with the socket placement slot on the protective shell makes electrical connections more convenient and reliable, avoiding wiring interference. The overall structure greatly improves installation and maintenance efficiency while ensuring connection strength and heat dissipation effect.
