[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a power distribution cabinet which is easy to maintain.

[0025] The utility model provides Figure 1-4 A maintenance-friendly power distribution cabinet shown in the figure comprises a first carrier plate 1, a wiring board 2, a cover 3 and an equipment carrier 5, wherein the wiring board 2 and the equipment carrier 5 are both fixed on the first carrier plate 1, and the cover 3 is rotatably connected to the first carrier plate 1 and is locked and fixed with the wiring board 2 by a lock;

[0026] Specifically, the cover body 3 is a semi-closed structure, which is used to protect the power distribution equipment. A rotating disk 7 is provided at the connection end of the cover body 3 and the first carrier board 1, and the connection end of the cover body 3 is connected to the rotating end of the rotating disk 7. Line connection holes 9 are longitudinally distributed on the board body of the wiring board 2, and a closing cover 11 is provided on the line connection holes 9. Spring snap locks 10 are provided on both sides of the top of the wiring board 2;

[0027] In combination with the above, the combination of the cabinet is realized by rotating the cover body 3 of the connection structure to cooperate with the terminal board 2 and the equipment carrier board 5 on the first carrier board 1. When repairing the cabinet, the cover body 3 can be released by the spring snap lock 10 on the top of the terminal board 2. The cover body 3 is rotated to place the cover body 3 flat on the ground on one side of the first carrier board 1. At this time, the equipment carrier 5 and the power distribution equipment installed on the frame and the circuit connection conditions are clearly presented. The staff can perform maintenance according to the connection conditions of different power distribution equipment. During the maintenance process, the corresponding power distribution equipment can be disconnected through the line connection hole 9, so as to carry out targeted maintenance. After the maintenance, the entire equipment carrier 5 and the power distribution equipment installed on the frame are wrapped by rotating the cover body 3, and the fixed ends 6 on both sides of the top of the rotating cover 3 are locked with the spring snap locks 10 corresponding to both sides of the top of the terminal board 2, so as to fix the cover body 3.

[0028] In order to achieve heat dissipation and debugging of power distribution equipment, such as Figure 3As shown, heat dissipation ports are provided on both sides of the cover body 3, and a door body mounting port is provided at the cover body 3 between the heat dissipation ports, and a cabinet door 4 is installed on the door body mounting port, and the cabinet door 4 is locked and fixed to the door body mounting port by a lock buckle;

[0029] Specifically, the cover 3 adopts a rotating structure, and the cabinet is opened or closed by rotating the cover 3. After closing, the cover 3 provides protection for the power distribution equipment, which is equivalent to the shell of a traditional cabinet. When the power distribution equipment is running, the heat generated will be discharged from the heat dissipation port. Routine debugging or simple testing can be achieved by opening the cabinet door;

[0030] In order to realize the installation of various power distribution equipment, such as Figure 3 As shown, a second carrier plate 8 is distributed on the equipment carrier 5, the second carrier plate 8 and the equipment carrier 5 are integrated into one structure, and a rubber insulating gasket is laid on the bearing surface of the second carrier plate 8;

[0031] According to the above, it is further explained that the second carrier plate 8 provides support for the power distribution equipment. While supporting the power distribution equipment, the rubber insulating gasket can be used for insulation, and at the same time, it provides an anti-slip effect for the installation of the power distribution equipment, and will not be displaced due to external forces;

[0032] In order to achieve the fixation of the cover after closing, Figure 3 , Figure 4 As shown, fixed terminals 6 are provided on both sides of the top of the closed end of the cover body 3, and locking holes are provided on both sides of the top of the wiring board 2, and the fixed terminals 6 are locked with the spring snap locks 10 through the locking holes;

[0033] It is further explained that when the cover body 3 is closed, it needs to be fixed by locking, and at the same time, it is also necessary to provide convenience for the expansion of the cover body. Therefore, a spring snap lock 10 is used to achieve this. Specifically, through the lock holes on both sides of the top of the wiring board 2, the fixed ends 6 on both sides of the closed end of the cover body 3 are provided with penetration, so that the fixed ends can be embedded with the lock holes of the spring snap lock 10 to achieve locking. It should be noted that in order to achieve a gap between the cover body 3 and the wiring board 2 after closing, a rubber sealing strip can be installed on the closed end of the wiring board 2 to provide gap filling. At the same time, an embedding groove needs to be provided on the rubber sealing strip, and the length of the fixed end 6 is consistent with the connection matching of the spring snap lock 10;

[0034] In order to achieve the corresponding connection between external lines and distribution equipment, such as Figure 4 As shown, the number of the line connection holes 9 distributed on the wiring board 2 is the same as the number of the carrier boards 8 distributed on the equipment carrier 5, and the positions are corresponding, and the line connection holes 9 are strip-shaped holes;

[0035] A metal sheet is disposed on one side of the circuit connection hole 9, and a closing cover 11 is connected to the other side of the circuit connection hole 9 via a rotating shaft. A magnetic sheet is bonded to the closed end of the closing cover 11, and the magnetic sheet is adsorbed and connected to the metal sheet.

[0036] Specifically, the line connection hole facilitates the connection of the external line with the power distribution equipment. If the power distribution equipment involved is small and does not occupy all of the second carrier board 8, the closing cover 11 can provide a sealing effect on the line connection hole 9. At the same time, the closing cover 11 and the line connection hole 9 are connected by magnetic adsorption. There is no need for a lock connection. The closing cover 11 can be opened by external force, which is convenient to open and close.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
