Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and specifically to a connection structure for integrated modular power distribution cabinets. Background Technology

[0002] An integrated modular switchgear is a type of power equipment that integrates various electrical components, electrical equipment, and related control systems to form a compact, fully functional, and highly reliable power distribution unit.

[0003] A search revealed that patent CN202020364818.2 discloses a power distribution cabinet with a combined connector structure. While this device utilizes the tightening of a first and second self-locking nut to compress a spring via an L-shaped clamping plate, the spring provides elastic force to press the clamping plate into the connecting hole, and simultaneously the first self-locking nut locks the combined connecting rod, preventing it from wobbling and thus securing it, this device only connects and secures two cabinets. It fails to provide dust protection at the connection point. Due to the lack of dustproof design at the connection point, dust easily accumulates in the gaps. This not only affects the cabinet's appearance but may also pose a potential hazard to internal electrical components. Furthermore, the lack of dustproof design at the connection point makes cleaning more difficult, requiring frequent opening of the cabinet for cleaning, increasing maintenance and time costs.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A connection structure for an integrated modular power distribution cabinet includes a cabinet body, side panels installed on both sides of the cabinet body, heat dissipation holes installed on the top of the cabinet body, support rods provided inside the cabinet body, fixing rods installed inside the cabinet body via the support rods, and cabinet doors rotatably installed on the cabinet body via hinges.

[0007] Adjacent cabinets are connected and assembled by connectors. The cabinets have mounting slots on both sides. The connectors and side panels are located in the mounting slots of the cabinets. The cabinets have through holes in the mounting slots.

[0008] The connector is provided with a positioning strip, and a dustproof strip is provided on the outside of the positioning strip. A slot is provided between the positioning strip and the dustproof strip. A receiving groove is provided through the connector. A through hole is provided in the connector at the receiving groove. A fixing bolt is installed in the receiving groove.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the inner diameter of the receiving groove and the through hole is larger than the diameter of the fixing bolt, and the fixing bolt is adjusted in position on the connector through the through hole and the receiving groove.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] Because the inner diameter of the receiving groove and through hole is larger than the diameter of the fixing bolt, the fixing bolt can move and adjust its position freely within these holes. This design allows for easy adjustment of the fixing bolt's position during installation to accommodate different sizes or locations. By adjusting the fixing bolt's position, precise alignment with the fixing holes on the cabinet can be ensured, resulting in a more secure and reliable connection.

[0038] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0039] Example 1

[0040] The connection structure for the integrated modular power distribution cabinet includes a cabinet body 2, side panels 4 installed on both sides of the cabinet body 2, heat dissipation holes 203 installed on the top of the cabinet body 2, support rods 201 inside the cabinet body 2, fixing rods 202 installed inside the cabinet body 2 via the support rods 201, cabinet doors 1 installed on the cabinet body 2 via hinges, adjacent cabinet bodies 2 are connected and assembled via connectors 3, mounting grooves 205 are opened on both sides of the cabinet body 2, the connectors 3 and side panels 4 are located at the mounting grooves 205 of the cabinet body 2, and fixing holes 204 are opened through the mounting grooves 205 of the cabinet body 2.

[0041] Example 2

[0042] To facilitate the connection and fixation of two adjacent cabinets 2, and to provide dust protection at the connection point of cabinets 2, for example, as follows: Figures 1 to 3As shown, the present invention further includes: a positioning strip 301 provided on the connector 3, and a dustproof strip 303 provided on the outer side of the positioning strip 301. The length of the dustproof strip 303 is greater than the length of the positioning strip 301, and the dustproof strip 303 covers the joint between two adjacent cabinets 2. The dustproof strip 303 effectively prevents dust, dirt, and other impurities from entering the interior of the cabinet 2. Because the length of the dustproof strip 303 is designed to be greater than that of the positioning strip 301, it ensures that the joint is fully covered, thereby significantly improving the dustproof effect. This design not only enhances the dustproof performance but also improves the sealing performance of the joints of the cabinets 2. The dustproof strip 303 fits tightly against the seam, reducing the penetration of air and moisture and helping to keep the interior of cabinet 2 dry and clean. A slot 302 is provided between the positioning strip 301 and the dustproof strip 303. The size of the slot 302 matches the size of the cabinet 2's frame. The connector 3 is engaged with the mounting slot 205 of cabinet 2 via the slot 302. The precise fit between the slot 302 and the cabinet 2's frame allows the connector 3 to be quickly and accurately engaged in the mounting slot 205, facilitating subsequent fixing. This design not only improves installation efficiency but also makes disassembling and replacing the connector 3 simple and quick. The slot 302 design achieves a tight connection between the connector 3 and the cabinet 2 through a physical snap-fit ​​method, ensuring the stability and reliability of the connection. A receiving groove 306 is formed through the connector 3, and a through hole 305 is formed at the receiving groove 306. A fixing bolt 304 is installed within the receiving groove 306. The connector 3 is connected and fixed to the cabinet 2 on both sides of the connector 3 via the fixing bolt 304 and a nut. The combination of the fixing bolt 304 and the nut provides excellent fastening force, allowing the connector 3 to be firmly connected to the cabinet 2. This fastening method effectively resists external stress and vibration, ensuring the stability and safety of the overall structure of the distribution cabinet. Compared with non-removable connection methods such as welding or riveting, the connection using the fixing bolt 304 and nut offers greater flexibility. During installation, simply pass the fixing bolt 304 through the pre-drilled holes in the connector 3 and the cabinet 2, and tighten it with the nut. During disassembly, simply loosen the nut and pull out the retaining bolt 304. The entire process is simple and quick. The position and size of the retaining bolt 304 are perfectly matched with the fixing hole 204. When the position and size of the retaining bolt 304 and the fixing hole 204 are perfectly matched, the retaining bolt 304 can be accurately inserted into the fixing hole 204, and a secure connection is achieved through bolts and other fastening elements. This design effectively avoids connection loosening or failure caused by positional deviations or size mismatches, thereby ensuring the overall stability and safety of the distribution cabinet. The matching retaining bolt 304 and fixing hole 204 simplify the installation process and reduce adjustment and correction work during installation. Installers can quickly and accurately complete the insertion and tightening of the retaining bolt 304, thereby improving installation efficiency.Due to the tight fit between the fixing bolt 304 and the fixing hole 204, this design effectively prevents loosening or deformation of the connection caused by external forces, enhancing the overall rigidity and strength of the distribution cabinet structure. The inner diameter of the receiving groove 306 and the through hole 305 is larger than the diameter of the fixing bolt 304. The fixing bolt 304 is adjusted in position on the connector 3 through the through hole 305 and the receiving groove 306. Because the inner diameter of the receiving groove 306 and the through hole 305 is designed to be larger than the diameter of the fixing bolt 304, the fixing bolt 304 can freely move and adjust its position in these holes. This design gives the fixing bolt 304 flexibility in position during the installation process to adapt to diverse installation dimensions and position requirements. By precisely adjusting the position of the fixing bolt 304, it can be ensured that it is accurately aligned with the fixing hole 204 on the cabinet 2, thereby achieving a more stable and reliable connection. This design significantly reduces the risk of loosening or failure of the connection caused by installation errors.

[0043] Working principle:

[0044] Adjacent cabinets 2 are connected and assembled using connectors 3.
