[0001] The utility model relates to the technical field of capacitor installation, in particular to an installation bracket for a capacitor and a motor. Background Art

[0002] A capacitor-run asynchronous motor is an induction motor operating under a single-phase AC power supply. It uses a capacitor as a starting capacitor or a running capacitor to start and operate the motor under a single-phase power supply by forming a phase difference in time and space. Generally, the capacitor equipped in a single-phase motor is placed in the motor junction box. Since the sizes of capacitors with different capacities are different, when developing a new large-capacity capacitor, the size of the capacitor needs to be increased, which leads to the need for new development and customization of the motor junction box. However, the storage shelf life of the capacitor is one year, and the capacitor needs to be replaced and maintained multiple times during the use of the motor. At this time, the screws of the junction box need to be removed, resulting in complex operation and low efficiency. Summary of the Utility Model

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] A mounting bracket for a capacitor, see Figure 1 and Figure 2 , the mounting bracket 10 is used to connect the capacitor 30 and is fixed on the junction box 20 of the motor. The mounting bracket 10 includes a main body part 11, a notch part 12 and a buckle part 13. The main body part 11 is a hollow cylindrical structure and surrounds the outer wall of the cylindrical capacitor 30; the notch part 12 penetrates the main body part 11 and is arranged along a direction parallel to the axial direction of the main body part 11. The notch part 12 makes the main body part 11 a non-closed arc structure in the circumferential direction; the buckle part 13 is arranged on the outer wall of the arc surface of the main body part 11 and is used to pass through the card rope 60. There are at least two buckle parts 13 and at least two buckles are distributed in the same circumferential direction.

[0036] The beneficial effects of this embodiment are as follows: The mounting bracket 10 forms an arc surface that is non-closed in the circumferential direction through the notch portion 12, facilitating the placement of the capacitor 30 into the main body portion 11. Subsequently, the lanyard 60 passes through the buckle portion 13 to fix the capacitor 30 on the mounting bracket 10, simplifying the installation of the capacitor 30 and separating the capacitor 30 from the junction box 20, thereby avoiding the cumbersome operation and low efficiency problems caused by the need to disassemble and assemble the junction box 20 when replacing the capacitor 30. In addition, due to the non-closed structure of the mounting bracket 10, the mounting bracket 10 has a notch portion 12, making the mounting bracket 10 easily deformable radially, so that the mounting bracket 10 can fix capacitors 30 with various radial dimensions and various axial dimensions, expanding the scope of use of the mounting bracket 10.

[0037] In some embodiments, referring to Figure 1 and Figure 2 , there are three buckle portions 13 and they are arranged along the same circumferential direction. In this way, setting multiple buckle portions 13 facilitates the passing through and fixing of the lanyard 60, and conveniently fixes the capacitor 30 firmly on the mounting bracket 10. Specifically, the number of buckle portions 13 can be increased according to requirements, and multiple buckle portions 13 can help improve the durability of the buckle portions 13.

[0038] In some embodiments, referring to Figure 1 and Figure 2 , the buckle portion 13 protrudes along the outer wall of the main body portion 11 and forms a clamping groove that can pass through circumferentially along the main body portion 11. In this way, the buckle portion 13 is provided, and the position of the clamping groove formed by the buckle portion 13 is convenient for the lanyard 60 to pass through when surrounding circumferentially, facilitating the threading of the lanyard 60 and the fixing of the capacitor 30.

[0039] In some embodiments, referring to Figure 1 and Figure 2 , the inner diameter of the main body portion 11 is not greater than the outer diameter of the capacitor 30. In this way, when the inner diameter of the main body portion 11 is equal to the outer diameter of the capacitor 30, the main body portion 11 just fits closely around the outer circumference of the capacitor 30, thus clamping the capacitor 30 tightly. When the inner diameter of the main body portion 11 is smaller than the outer diameter of the capacitor 30, the main body portion 11 can deform within a certain range, thus fixing the capacitor 30 of this size. However, when the inner diameter of the main body portion 11 is greater than the outer diameter of the capacitor 30, it is necessary to use the lanyard 60 to compress and contract the mounting bracket 10, but it is difficult for the mounting bracket 10 to contract and deform, and in this case, the tension on the lanyard 60 is too large, so this form is not used to fix the capacitor 30.

[0040] In some embodiments, referring to Figure 1 and Figure 2, the radian value corresponding to the notch portion 12 is greater than 0.5π and less than π. In this way, the notch portion 12 has a sufficient opening size, which facilitates the insertion of the capacitor 30, and at the same time ensures the circumferential surrounding range of the capacitor 30 by the mounting bracket 10 to ensure the stability after the capacitor 30 is fixed. That is, the angle of the arc surface corresponding to the notch portion 12 is greater than 90° and less than 180°.

[0041] In some embodiments, referring to Figure 1 and Figure 2 , the mounting bracket 10 further includes a connecting portion 14. The connecting portion 14 penetrates through the main body portion 11 and is in a hollow columnar shape. The connecting portion 14 is used to connect the mounting bracket 10 to the junction box 20. In this way, by providing the connecting portion 14, the middle part of the mounting bracket 10 is fixed to the junction box 20 through the connecting portion 14 to improve the stability of the mounting bracket 10.

[0042] In some embodiments, referring to Figure 1 and Figure 2 , the mounting bracket 10 further includes a weight-reducing hole 15. The weight-reducing hole 15 is in a long strip shape and extends along the circumferential direction of the main body portion 11. The weight-reducing hole 15 is provided in the middle of the main body portion 11. In this way, by providing the weight-reducing hole 15, the effects of weight reduction and material saving can be achieved. By providing the weight-reducing hole 15 in the middle, it is convenient for the mounting bracket 10 to deform within a certain range when fixing capacitors 30 of different sizes, and at the same time, the structural strength of the mounting bracket 10 is balanced, improving the durability of the mounting bracket 10.

[0043] Specifically, the weight-reducing hole 15 is in a long strip shape. One or more weight-reducing holes 15 can be provided. When multiple weight-reducing holes 15 are provided, the weight-reducing holes 15 are evenly arranged on the mounting bracket 10.

[0044] A motor, referring to Figures 3 to 5 , includes a mounting bracket 10, and further includes a cable tie 60 and a capacitor 30. The capacitor 30 is in a columnar shape. The capacitor 30 is fixed to the mounting bracket 10 through the cable tie 60. In this way, by providing the mounting bracket 10 to surround and fix the capacitor 30, it is convenient for the capacitor 30 to be inserted into and fixed in the mounting bracket 10. The capacitor 30 is clamped tightly to the mounting bracket 10 through the cable tie 60, achieving the effect of strengthening the stability after the capacitor 30 is fixed; combining the cable tie 60 and the mounting bracket 10, the capacitor 30 is fixed outside the junction box 20, making the capacitor 30 easier to disassemble and replace after being fixed.

[0045] On the basis of the above embodiments, the cable tie 60 is a zip tie. The structure of the zip tie is simple, easy to use, and conducive to cost control.

[0046] In some embodiments, referring to Figures 3 to 5, it further includes a motor housing 40 and a grounding screw piece 50. One end of the grounding screw piece 50 is fixed to the axial end of the capacitor 30, and the other end of the grounding screw piece 50 is fixed to the motor housing 40. In this way, by providing the grounding screw piece 50, fixing one end of the grounding screw piece 50 to the motor housing 40 and the other end to the capacitor 30, the capacitor 30 is grounded, and at the same time, one end of the capacitor 30 is fixed, which also improves the installation stability of the capacitor 30.

[0047] In some embodiments, referring to Figures 3 to 5 , it further includes a junction box 20, and the junction box 20 is connected to the wiring part of the mounting bracket 10 by bolts. In this way, the junction box 20 is connected to the mounting bracket 10, thereby fixing the position of the mounting bracket 10, that is, fixing the position of the capacitor 30, which is convenient for determining the position of the capacitor 30 when overhauling or replacing the capacitor 30.

[0048] In this application, referring to Figure 1 and Figure 3 , by arranging the mounting bracket of the capacitor outside the junction box 20 and fixing the mounting bracket 10 beside the junction box 20, it is convenient for the installation and disassembly of the capacitor 30. The capacitor 30 is columnar, and the mounting bracket 10 is wound around the arc surface of the capacitor 30. The capacitor 30 and the mounting bracket 10 are clamped tightly along the circumferential direction by a clamping rope 60. Since one axial end of the capacitor 30 is also fixed to the motor housing 40 by the grounding screw piece 50, the grounding screw piece 50 improves the installation stability of the capacitor 30 while completing the grounding connection; in addition, since the mounting bracket 10 has an opening and fixes the circumference of the capacitor 30, the mounting structure of this application can be applicable to capacitors 30 with various axial lengths and various radial sizes, but the outer diameter of the capacitor 30 needs to be not less than the inner diameter of the mounting bracket 10 to ensure that the mounting bracket 10 clamps the capacitor 30 along the circumferential direction.

[0049] Both the motor housing 40 and the junction box 20 are made of aluminum parts, or both are made of iron parts, and the mounting bracket 10 is made of plastic parts.
