Description

Technical Field

[0001] This utility model belongs to the field of electrical cabinet technology, and more specifically, it relates to a combined busbar installation structure for electrical cabinets. Background Technology

[0002] A modular busbar is an electrical connection component. Its structural features mainly include two parallel and spaced main busbar units and several vertical branch busbars. The vertical branch busbars are perpendicular to the main busbar units and are connected to the two main busbar units by bolts. Each vertical branch busbar is equipped with a U-shaped connecting piece and a fixing piece at the connection point with the main busbar unit. It is an efficient, reliable, energy-saving and environmentally friendly electrical connection component.

[0003] In the prior art, patent publication number "CN215934004U" discloses a "combined busbar"; comprising: a mounting base plate, the mounting base plate having a positioning circular hole at its center; and a mounting column, the mounting column having a circular through hole and a mounting protrusion at its bottom, the mounting protrusion matching the positioning circular hole on the mounting base plate, the mounting protrusion having a mounting annular groove on its outer side wall, the mounting annular groove extending circumferentially along the mounting protrusion, the mounting protrusion being fixedly installed in the positioning circular hole through the mounting annular groove. The combined busbar of this utility model comprises a mounting column and a mounting base plate. The mounting column is inserted into the positioning circular hole on the mounting base plate, and then pressure is applied to the surface of the copper column to deform the root of the copper column, fixing the mounting column to the mounting base plate to form an assembly. No welding is required, resulting in high assembly efficiency and a low defect rate.

[0004] The aforementioned technical solutions suffer from drawbacks when the surrounding environment is humid. This humid environment leads to rust and corrosion on the busbar surface, with rust and corrosion accumulating and reducing its power transmission capacity. Simultaneously, in high-temperature environments, the busbar contact points may loosen due to thermal expansion and contraction, resulting in poor contact. Poor contact increases contact resistance and generates more heat. Therefore, a modular busbar installation structure for electrical cabinets is proposed to address these problems. Utility Model Content

[0028] Please see Figures 1 to 6 As shown, this embodiment of the utility model provides a combined busbar installation structure for an electrical cabinet, including a mounting plate 1. The surface of the mounting plate 1 has positioning holes 2 and a top groove 301. A top heat dissipation plate 302 is fixedly connected to the surface of the top groove 301. A side heat dissipation plate 307 is fixedly connected to one side of the top heat dissipation plate 302, and heat sinks 303 are fixedly connected to one side of the side heat dissipation plate 307.

A connecting bolt 304 is threadedly connected to the surface of the top heat dissipation plate 302. In this embodiment, the heat generated on the surface of the mounting plate 1 during use is conducted to the side heat dissipation plate 307 through the top heat dissipation plate 302 and the side connecting plate 306, and then conducted to the surface of multiple heat sinks 303 through the side heat dissipation plate 307. The multiple heat sinks 303 increase the heat dissipation area of ​​the side heat dissipation plate 307, accelerate heat dissipation efficiency, and improve the stability of the mounting plate 1 during use.

[0029] Please see Figures 1 to 6As shown, there are two bottom grooves 305 and two side connecting plates 306. The two bottom grooves 305 are symmetrically arranged along the upper and lower sides of the mounting plate 1, and the side connecting plates 306 are fixedly connected to the inner side of each bottom groove 305. In this embodiment, by creating the top groove 301 and the bottom groove 305, the top heat sink 302 and the side connecting plates 306 can be fixed to the surface of the mounting plate 1. There are two top grooves 301 and two bottom grooves 305. The two top heat sinks 302 are fixed to the inner side of the two top grooves 301, and the two side connecting plates 306 are fixed to the surface of the two bottom grooves 305. The side connecting plates 306 and the top heat sink 302 are both fixed to the surface of the mounting plate 1 by connecting bolts 304. The use of multiple connecting bolts 304 improves the stability of the fixing of the top heat sink 302 and the side connecting plates 306.

[0030] Please see Figures 1 to 6 As shown, a bottom connecting box 401 is fixedly connected to the bottom of the mounting plate 1. A bottom sliding rail 407 is provided on the inner side of the bottom connecting box 401. A bottom sliding block 408 is slidably connected to the surface of the bottom sliding rail 407. A movable drawer 409 is fixedly connected to the top of the bottom sliding block 408. A side handle 4010 is fixedly connected to one side of the movable drawer 409. Side vent holes 4011 are provided on both sides of the side handle 4010. In this embodiment, when the movable drawer 409 is pulled out along the inner side of the bottom connecting box 401, the sliding of the bottom sliding block 408 and the bottom sliding rail 407 improves the stability of the movable drawer 409 when it is moved out. The desiccant solid material in the movable drawer 409 will come into contact with the air near the mounting plate 1 through the side vent holes 4011.

[0031] Please see Figures 1 to 6 As shown, a bottom support block 402 is fixedly connected to the bottom of the bottom connecting box 401, and a friction groove 403 is provided on the bottom of the bottom support block 402. When the mounting plate 1 is installed, the bottom of the bottom connecting box 401 is supported by the bottom support block 402, maintaining the stability of the mounting plate 1 during installation.

A side connecting frame 404 is provided on the surface of the bottom connecting box 401. A side connecting bracket 405 is fixedly connected to the inner side of the side connecting frame 404, and a protective net 406 is movably connected to the inner side of the side connecting bracket 405. The protective net 406 within the side connecting bracket 405 prevents external dust particles from adhering to the desiccant blocks in the movable drawer 409. The protective net 406 also enhances the contact efficiency between the desiccant blocks and external air, maintaining the dryness of the environment near the mounting plate 1, reducing the impact of moisture on the mounting plate 1, and improving the stability and service life of the mounting plate 1.

[0032] Please see Figures 1 to 6As shown, a bottom fixing bracket 501 is fixedly connected to one side of the bottom connecting box 401. An inner connecting groove 502 is opened on one side of the bottom fixing bracket 501. A top connecting groove 503 is opened on the top of the inner connecting groove 502. A bottom connecting spring 505 is fixedly connected to the inner side of the inner connecting groove 502. A side limiting plate 504 is fixedly connected to the top of the bottom connecting spring 505. Side fixing plates 506 are fixedly connected to both sides of the side limiting plate 504. A side pressing plate 507 is fixedly connected to one side of the side fixing plate 506. In this embodiment, the operator holds the side pressing plate 507 and presses it down. Through the connection of the side fixing plate 506, the downward vertical movement of the side pressing plate 507 will drive the side limiting plate 504 to move downward vertically along the inner side of the inner connecting groove 502. The vertical movement of the side limiting plate 504 will drive the bottom connecting spring 505 to undergo compression deformation along the inner side of the inner connecting groove 502. After the side limiting plate 504 is lowered, the part of the top of the side limiting plate 504 extending out of the top connecting groove 503 will enter the inner side of the top connecting groove 503. At this time, after one side of the movable drawer 409 loses contact with the side limiting plate 504, the operator can easily remove the movable drawer 409.

[0033] The specific usage and function of this embodiment are as follows: In daily work, before using the mounting plate 1, the top heat sink 302 and the side connecting plate 306 can be fixed to the surface of the mounting plate 1 by opening the top groove 301 and the bottom groove 305. There are two top grooves 301 and two bottom grooves 305. The two top heat sinks 302 are fixed to the inner side of the two top grooves 301 and the two side connecting plates 306 are fixed to the surface of the two bottom grooves 305. The side connecting plates 306 and the top heat sinks 302 are fixed to the surface of the mounting plate 1 by connecting bolts 304. The bolt 304 improves the stability of fixing the top heat sink 302 and the side connecting plate 306. When the mounting plate 1 is in use, both the top heat sink 302 and the side connecting plate 306 are made of copper metal with high thermal conductivity. The heat generated on the surface of the mounting plate 1 during use is conducted to the side heat sink 307 through the top heat sink 302 and the side connecting plate 306, and then the heat is conducted to the surface of multiple heat sinks 303 through the side heat sink 307. The number of heat sinks 303 is multiple, which increases the heat dissipation area of ​​the side heat sink 307, speeds up the heat dissipation efficiency, and improves the stability of the mounting plate 1 during use.

[0034] Before installing mounting plate 1, the operator first holds the side handle 4010 and pulls the movable drawer 409 horizontally along the inner side of the bottom connecting box 401. As the movable drawer 409 is pulled out, the sliding of the bottom sliding block 408 and the bottom sliding rail 407 improves the stability of its movement. After removing the movable drawer 409, the operator places several desiccant blocks inside it. After placing the blocks, the operator pushes the movable drawer 409 back into the bottom connecting box 401. Then, mounting plate 1 is installed. During installation, the bottom of the bottom connecting box 401 is supported by the bottom support block 402, maintaining the stability of mounting plate 1 during installation. The friction grooves 403 on the surface of block 402 increase friction and reduce the shaking caused by the installation of mounting plate 1. At this time, the desiccant solid material in the movable drawer 409 will come into contact with the air near the mounting plate 1 through the side exhaust hole 4011. The side connecting frames 404 on the outside of the bottom connecting box 401 are all fixed with side connecting frames 405. The protective net 406 in the side connecting frame 405 will prevent the desiccant solid material in the movable drawer 409 from being attached by external dust particles, etc. The protective net 406 will also enhance the contact efficiency between the desiccant solid material and the external air, keep the environment near the mounting plate 1 dry, reduce the impact of moisture on the mounting plate 1, and improve the stability and service life of the mounting plate 1.

[0035] Simultaneously, if it is necessary to open the movable drawer 409 to replace or replenish the desiccant block material, the operator first holds the side pressing plate 507 and presses it downwards. Through the connection of the side fixing plate 506, the downward vertical movement of the side pressing plate 507 will drive the side limiting plate 504 to move downwards vertically along the inner side of the inner connecting groove 502. The vertical movement of the side limiting plate 504 will cause the bottom connecting spring 505 to undergo compression deformation along the inner side of the inner connecting groove 502. After the side limiting plate 504 is lowered, the part of the side limiting plate 504 extending out of the top connecting groove 503 will enter the top... Inside the connecting groove 503, after one side of the movable drawer 409 loses contact with the side limiting plate 504, the operator can easily remove the movable drawer 409. During installation, after pushing the movable drawer 409 into the inside of the bottom connecting box 401, one side of the movable drawer 409 is parallel to one side of the bottom connecting box 401. At this time, the bottom connecting spring 505 will reset after losing external force restriction and push the side limiting plate 504 to move upward. The side limiting plate 504 is used to limit the movable drawer 409 and keep the movable drawer 409 limited inside the bottom connecting box 401.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
