Description

Technical Field

[0001] The utility model relates to the field of grounding busbar waterproof equipment, in particular to a grounding busbar waterproof structure for a capacitor end of a motor controller. Background Art

[0002] A motor controller is an electronic control device that controls the operation of a motor. It is mainly used to control the start, operation, speed regulation, stop and other functions of the motor. Its main function is to convert the electrical energy of the power supply into electrical energy that can be used by the motor according to control signals, instructions and algorithms, and to control the motor's speed, direction, torque and other parameters to meet different working requirements. The grounding busbar is a vital component in the electrical system. Its main function is to connect the grounding wires of electrical equipment together to ensure that the grounding potential of the equipment is the same, thereby improving the safety and reliability of the electrical system.

[0003] In order to facilitate the connection of cables and motor controllers, existing grounding busbars usually have multiple wire holes on the surface. However, when the grounding busbar encounters water, since there is no protective structure on the outside of the grounding busbar, the water usually flows directly to the cable surface and the interface, causing the water to stay on the cable surface and the grounding busbar surface, thereby affecting the use of the cables and the grounding busbar. At the same time, the long-term stay of the water will cause corrosion to the grounding busbar surface, reducing the service life of the grounding busbar.

[0004] Therefore, it is necessary to provide a new motor controller capacitor terminal grounding busbar waterproof structure to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a waterproof structure of a grounding busbar at the capacitor end of a motor controller.

[0006] The utility model provides a waterproof structure for the grounding busbar at the capacitor end of the motor controller, including a grounding busbar body, a support assembly being provided on one side of the grounding busbar body, a guide plate being provided on the top of the support assembly, the top of the guide plate being inclined from one end to the other end, a protective member being further provided on the top of the support assembly, and the guide plate being located inside the protective member.

[0007] Preferably, the protective member includes two protective plates, the bottoms of the two protective plates are fixedly connected to the two ends of the top of the support assembly respectively, and the guide plate is located between the two protective plates.

[0008] Preferably, the support assembly includes a support plate, and one side of the support plate is connected to the surface of the grounding busbar through a plurality of snap-fit ​​parts.

[0009] Preferably, the engaging member includes a card block, one side of the card block is fixedly connected to one side of the support plate, and a surface of the grounding busbar is provided with a plurality of card slots matching the card block.

[0010] Preferably, the support plate is arranged in an L shape.

[0011] Preferably, the surface of the support plate is provided with through holes for a plurality of cables to pass through.

[0012] Compared with related technologies, the waterproof structure of the motor controller capacitor terminal grounding busbar provided by the present invention has the following beneficial effects:

[0013] 1. When the grounding busbar body encounters water, the water will flow along the top of the grounding busbar body to the top of the guide plate. Since the top of the guide plate is tilted from one end to the other, when the water flows to the top of the guide plate, the water will be discharged to the outside of the grounding busbar body along the guide plate, thereby preventing the water from contacting the cable interface and preventing the water from staying on the surface of the grounding busbar body. To a certain extent, the service life of the grounding busbar body can be improved.

[0014] 2. The protective part set on the top of the support assembly can effectively prevent the water flowing on the top of the guide plate from overflowing to the outside, thereby preventing the water from contacting the cable surface, reducing the water flow staying on the cable surface, and effectively protecting the use effect of the cable.

[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] In the specific implementation process, Figures 1-4 As shown, a waterproof structure of a grounding busbar at the capacitor end of a motor controller comprises a grounding busbar body 1, a supporting assembly is provided on one side of the grounding busbar body 1, a guide plate 2 is provided on the top of the supporting assembly, the top of the guide plate 2 is inclined from one end to the other end, a protective member is further provided on the top of the supporting assembly, the guide plate 2 is located inside the protective member, the protective member comprises two protective plates 3, the bottoms of the two protective plates 3 are respectively fixedly connected to the two ends of the top of the supporting assembly, the guide plate 2 is located between the two protective plates 3, the supporting assembly comprises a support plate 4, one side of the support plate 4 is connected to the surface of the grounding busbar through a plurality of engaging members, the engaging member comprises a card block 5, one side of the card block 5 is fixedly connected to one side of the support plate 4, the surface of the grounding busbar is provided with a plurality of card slots 6 matching the card block 5, the support plate 4 is arranged in an L shape, and the surface of the support plate 4 is provided with through holes 7 for a plurality of cables to pass through;

[0023] When the grounding busbar body 1 encounters water, the water will flow along the top of the grounding busbar body 1 to the top of the guide plate 2. Since the top of the guide plate 2 is tilted from one end to the other, when the water flows to the top of the guide plate 2, the water will be discharged along the guide plate 2 to the outside of the grounding busbar body 1, thereby preventing the water from contacting the cable interface and preventing the water from staying on the surface of the grounding busbar body 1. At the same time, the two protective plates 3 can effectively prevent the water flowing on the top of the guide plate 2 from overflowing to the outside, thereby preventing the water from contacting the cable surface and reducing the water from staying on the cable surface.

[0024] The working principle provided by the present invention is as follows: when the grounding busbar body 1 encounters water, the water will flow along the top of the grounding busbar body 1 to the top of the guide plate 2. Since the top of the guide plate 2 is inclined from one end to the other end, when the water flows to the top of the guide plate 2, the water will be discharged to the outside of the grounding busbar body 1 along the guide plate 2, thereby preventing the water from contacting the cable interface and preventing the water from staying on the surface of the grounding busbar body 1. At the same time, the two protective plates 3 can effectively prevent the water flowing on the top of the guide plate 2 from overflowing to the outside, thereby preventing the water from contacting the cable surface and reducing the water from staying on the cable surface.

[0025] By inserting the card block 5 into the card slot 6, the support plate 4 can be fixed. At the same time, since it is fixed by the card block 5 and the card slot 6, the support plate 4 can be easily removed for maintenance or cleaning, which is convenient for use. Through the through hole 7 opened on the surface of the support plate 4, the cable can be easily passed through the wire hole 8 opened on the surface of the grounding busbar body 1.
