Description

Technical Field

[0001] The utility model belongs to the field of capacitors. Specifically, the utility model relates to a capacitor fixing structure. Background Art

[0002] The capacitor fixing method usually adopts the method of padding an epoxy board under the capacitor to raise the capacitor or coating silicone rubber. However, this capacitor fixing method is only applicable to low-voltage power supplies. In products with high voltage and large current, there are certain potential hazards in this fixing method. Since the large-size capacitor is large in size and weight, when using the two methods of raising with an epoxy board and coating glue, the large-size capacitor is prone to shift under a vibrating environment.

[0003] To solve the above problems, Patent Document 203617139U is applicable to the technical field of capacitor installation, and provides a capacitor fixing sleeve and a capacitor installation component having the capacitor fixing sleeve. The capacitor fixing sleeve is used to lock a capacitor on a support plate having an installation hole. It includes an elastic insulating sleeve body inserted into the installation hole. A cavity adapted to the outer contour of the capacitor is recessed on the elastic insulating sleeve body. A pin insertion hole for the pins of the capacitor to pass through is formed through the bottom of the cavity. A clamping flange with a radial dimension larger than the radial dimension of the installation hole protrudes outward from the top edge of the cavity in a direction away from the center of the cavity, but it cannot solve the above problems.

[0019] The following is a more detailed description of the specific embodiments of the present invention by referring to the drawings and describing the embodiments, aiming to help those skilled in the art have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention and facilitate its implementation.

[0020] Figure 1 is a structural schematic of the capacitor fixing structure in the embodiment of the present utility model Figure One ; Figure 2 is a structural schematic of the capacitor fixing structure in the embodiment of the present utility model Figure Two ; Figure 3 is a structural schematic of the capacitor fixing structure in the embodiment of the present utility model Figure Three .

[0021] As Figure 1 , Figure 2 and Figure 3 shown, the capacitor fixing structure provided by the present utility model includes a base 10 and a limiting structure 20. A large-size capacitor 1 is arranged on the base 10. A positioning groove 11 is formed on the base 10. The positioning groove 11 is adapted to the bottom of the cylindrical large-size capacitor 1. The positioning groove 11 is circular, so as to limit and position the large-size capacitor 1. The limiting structure 20 is arranged on the base 10 and abuts against the surface of the large-size capacitor 1, so as to further limit and position the large-size capacitor 1, thereby firmly fixing the large-size capacitor 1 and effectively preventing the large-size capacitor 1 from shifting in a vibration environment.

[0022] The depth of the positioning groove 11 is lower than the height of the insulating tape adhered to the side surface of the large-size capacitor 1, which can avoid damaging the insulating tape adhered to the surface of the large-size capacitor 1 when installing the large-size capacitor 1, and effectively prevent electric leakage.

[0023] Six positioning grooves 11 are arranged on the base 10. The six positioning grooves 11 are evenly distributed on the base 10 in a 2×3 manner, so that the capacitor fixing structure provided by the present utility model can firmly fix multiple large-size capacitors 1 at the same time. An epoxy board 12 is adhered to the bottom of the positioning groove 11. The epoxy board 12 can play an insulating role, improve the insulation of the capacitor fixing structure provided by the present utility model, prevent the large-size capacitor 1 from leaking electricity, and improve the safety.

[0024] The limiting structure 20 includes a positioning vertical plate 21 and a positioning annular plate 22. One side of the positioning vertical plate 21 is connected to the base 10, and the other side of the positioning vertical plate 21 is connected to the positioning annular plate 22. The two positioning vertical plates 21 are arranged parallel to each other and are located on both sides of the positioning groove 11. The positioning annular plate 22 is adapted to the large-size capacitor 1 and is annular, which can limit and position the top of the large-size capacitor 1, thereby firmly fixing the large-size capacitor 1 and effectively preventing the large-size capacitor 1 from shifting in a vibration environment.

[0025] Both ends of the positioning annular plate 22 are provided with extension segments 221. An adjusting bolt 222 is passed through the extension segments 221. Both ends of the positioning annular plate 22 are provided with extension segments 221, and the two ends of the positioning annular plate 22 are not fixedly connected, so that the size of the positioning annular plate 22 can be adjusted. By rotating the adjusting bolt 222, the positioning annular plate 22 can be contracted or enlarged, so that the large-size capacitor 1 can be further firmly fixed, and it can be flexibly adjusted, which is convenient for installing or disassembling the large-size capacitor 1 and convenient for operation.

[0026] Six groups of limiting structures 20 are respectively arranged at six positioning grooves 11. Two parallel positioning vertical plates 21 are arranged on both sides of each positioning groove 11. The sides of the two positioning vertical plates 21 away from the base 10 are connected to the positioning annular plate 22, so that the six large-size capacitors 1 in the six positioning grooves 11 can be limited and positioned.

[0027] Insulating tapes are adhered to both the positioning vertical plates 21 and the positioning annular plate 22. The insulating tapes are evenly wrapped on the surfaces of the positioning vertical plates 21 and the positioning annular plate 22, which can effectively prevent the large-size capacitor 1 from leaking electricity. Polyester films are adhered to both the positioning vertical plates 21 and the positioning annular plate 22. The polyester films are wrapped outside the insulating tapes, which can effectively avoid the positioning vertical plates 21 and the positioning annular plate 22 from scratching the insulating tapes on the surface of the large-size capacitor 1 and further effectively prevent dangerous situations such as electric leakage.
