Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a push-button switch installation device for grid-connected cabinets. Background Technology

[0002] Grid-connected cabinets are typically used in distributed generation systems, such as solar or wind power generation, to connect the generated electricity to the power grid. Push-button switches are responsible for controlling the on / off state of power and protecting system safety; they are a core component ensuring the safe connection of electricity to the grid.

[0003] The push-button switch is installed on the panel of the grid-connected cabinet. It includes a button base, a button cap, and a nut. The button base is located on the inside of the panel and is used for wiring, also known as the wiring base. During installation, first, a hole is drilled in the panel. Then, the clips on both sides of the button base are pressed to separate the button cap from the button base. The nut on the button cap is removed. Then, the end of the button cap is passed through the hole in the panel, and the nut is tightened on the button cap to fix the button cap to the panel. Finally, the button base and the button cap are connected by the clips to complete the installation of the push-button switch. After the installation is completed, the wiring operation between the button base and the electrical components inside the grid-connected cabinet can be performed.

[0004] However, the panel of the grid-connected cabinet is a single-layer sheet metal with several openings, which reduces the strength of the panel. In addition, during use, the button cap needs to be pressed. When pressed, the force on the button cap is transmitted to the button base and also to the panel, which makes the connection between the panel and the button base very easy to deform or even crack. This causes the button switch to shake or even detach from the panel, affecting the normal use of the button switch and resulting in low safety. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a push-button switch installation device for grid-connected cabinets that can improve the installation stability of push-button switches, have high structural strength, and long service life.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A push-button switch mounting device for a grid-connected cabinet includes a panel with a plurality of mounting holes arranged in a matrix for the push-button switch caps to pass through. A rectangular frame is fixedly mounted on the inner side of the panel, and mounting brackets are fixedly mounted on the rectangular frame corresponding to each row of mounting holes. Each mounting bracket has a through hole for the end of the push-button switch cap to pass through, and the through hole is coaxial with the mounting hole. Reinforcing rings are symmetrically arranged on both sides of the mounting bracket corresponding to the through hole, and the inner ring surface of the reinforcing ring and the hole surface of the through hole are located on the same circumference.

[0008] In this way, a rectangular frame is fixed to the inside of the panel to increase its strength. Mounting brackets are fixedly installed on each row of mounting holes directly opposite the rectangular frame. The button cap of the push-button switch passes through the mounting hole, and its end passes through a through-hole on the mounting bracket and is connected to a nut. The button cap is then connected to the button base via a clip, completing the push-button switch installation. Afterwards, the button base of the push-button switch is wired to the electrical components inside the grid-connected cabinet. Fixing the button cap to the mounting bracket, compared to fixing it to the panel, allows the force applied to the button cap to be transferred to the button base and mounting bracket, then to the rectangular frame, and finally to the panel. This reduces the stress on the panel, resulting in more stable panel quality and a longer service life. Reinforcing rings are symmetrically arranged on both sides of the mounting bracket corresponding to the through-holes, reinforcing and securing the mounting bracket at the through-hole positions, improving stress resistance and ensuring the normal operation of the grid-connected cabinet.

[0009] Preferably, the mounting bracket has a reinforcing frame protruding from the side facing away from the panel, and a plurality of reinforcing rods are fixed inside the reinforcing frame, with through holes located between two adjacent reinforcing rods.

[0010] Preferably, the reinforcing ring positioned directly opposite the panel is fitted to the panel.

[0011] Preferably, the rectangular frame is made by welding I-beams, and the rectangular frame is welded to the panel.

[0012] Preferably, the rectangular frame has several internally threaded cylinders arranged vertically on both sides facing the panel, and the inner hole of the internally threaded cylinder is provided through the rectangular frame. Both ends of the mounting bracket have a locking block that can engage with the rectangular frame. The locking block has two through holes provided through the clearance hole. The two ends of the mounting bracket are fixedly connected to the locking block by bolts.

[0013] In summary, the push-button switch installation device for this grid-connected cabinet has the advantages of improving the installation stability of the push-button switch, high structural strength, and long service life. Attached Figure Description

[0021] like Figure 1-6 As shown, a push-button switch mounting device for a grid-connected cabinet includes a panel 1. The panel has a plurality of mounting holes arranged in a matrix for the push-button switch caps 2 to pass through. A rectangular frame 3 is fixedly mounted on the inner side of the panel. Mounting brackets 4 are fixedly mounted on the rectangular frame corresponding to each row of mounting holes. The mounting brackets have through holes 6 for the ends 5 of the push-button switch caps to pass through. The through holes are coaxial with the mounting holes. Reinforcing rings 7 are symmetrically arranged on both sides of the mounting brackets corresponding to the through holes. The inner ring surface of the reinforcing rings and the hole surface of the through holes are located on the same circumference.

[0022] In this way, a rectangular frame is fixed to the inside of the panel to increase its strength. Mounting brackets are fixedly installed on each row of mounting holes directly opposite the rectangular frame. The button cap of the push-button switch passes through the mounting hole, and its end passes through a through-hole on the mounting bracket and connects to nut 8. The button cap is then connected to the button base 9 via a clip, completing the push-button switch installation. Afterwards, the button base of the push-button switch is wired to the electrical components inside the grid-connected cabinet. Fixing the button cap to the mounting bracket, compared to fixing it to the panel, allows the force applied to the button cap to be transferred to the button base and mounting bracket, then to the rectangular frame, and finally to the panel. This reduces the stress on the panel, resulting in more stable panel quality and a longer service life. Reinforcing rings are symmetrically arranged on both sides of the mounting bracket corresponding to the through-holes, reinforcing and fixing the mounting bracket at the through-hole positions, improving stress resistance and ensuring the normal operation of the grid-connected cabinet.

[0023] In implementation, a reinforcing frame 10 protrudes from the side of the mounting bracket facing away from the panel, and several reinforcing rods 11 are fixed inside the reinforcing frame, with through holes located between two adjacent reinforcing rods. The overall strength of the mounting bracket can be further improved through the addition of the reinforcing frame and reinforcing rods.

[0024] During implementation, the reinforcing ring positioned directly opposite the panel is fitted snugly against the panel, improving overall integrity.

[0025] In practice, the rectangular frame is constructed by welding I-beams, and the rectangular frame is welded to the panel. This facilitates manufacturing.

[0026] In implementation, several internally threaded cylinders 12 are vertically arranged on both sides of the rectangular frame facing the panel, and clearance holes are provided through the inner holes of the internally threaded cylinders in the rectangular frame. Both ends of the mounting bracket have locking blocks 13 that can engage with the rectangular frame. Two through holes are provided through the clearance holes in each locking block. The two ends of the mounting bracket are fixedly connected to the locking blocks by bolts. During installation, the locking blocks on both sides of the mounting bracket are inserted into the slots of the I-beam, with the through holes, clearance holes, and internally threaded cylinders aligned. Locking bolts pass through the through holes and clearance holes and then connect to the internally threaded cylinders, completing the fixed connection between the mounting bracket and the rectangular frame.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
