Technical Field

[0001] This utility model belongs to the field of power component technology, specifically relating to a power electronic component with embedded power electronic equipment. Background Technology

[0002] A search revealed a patent document with authorization announcement number CN212411969U, which discloses a waterproof and electric shock protection device. This device includes a protective housing with a receiving space and a circuit board disposed within the receiving space. The protective housing comprises a first housing and a second housing. While this method achieves waterproofing through a circuit board compartment and by using waterproof sealant to seal and fix the circuit board within the compartment, and also helps protect the performance stability of the circuit board...

[0003] However, problems still exist in its use. Electric shock protectors are mostly used in outdoor locations. If the protector is not protected when it is installed, it is easily damaged by external impacts and other factors, reducing the service life of the device. At the same time, the switch of the protector does not have a protective structure when in use, which can easily lead to the protector being shut down and unable to be used normally when the operator accidentally touches the switch.

[0004] Therefore, it is necessary to provide a power electronic component with embedded power electronic devices to solve the above-mentioned technical problems. Utility Model Content

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] Please see Figures 1-6 This utility model provides the following technical solution: a power electronic component with embedded power electronic equipment, including a protective housing 1, a protector 3 installed inside the protective housing 1 via a snap-fit ​​seat 13, a buffer anti-collision structure 2 slidably disposed on the outer side of the protective housing 1, the buffer anti-collision structure 2 including an inverted L-shaped anti-collision plate 21, the inner side wall of the inverted L-shaped anti-collision plate 21 being limited and slidably disposed within a limiting buffer cylinder 22 on both sides of the outer wall of the protective housing 1 by a limiting rod 23, the limiting buffer cylinder 22 being provided with a spring 24 connected to the limiting rod 23 inside; the bottom and inner top of the inverted L-shaped anti-collision plate 21 being slidably connected to the bottom and top of the protective housing 1 by a connecting rod 27; a protective cover 4 being slidably disposed on the front end face of the protector 3.

[0016] To reduce the probability of damage from external impacts, the bottom of the inverted L-shaped anti-collision plate 21 slides on a sliding rod 25 in the bottom groove of the protective housing 1 via a connecting rod 27. A second spring 26, connected to the inner wall of the groove and the connecting rod 27, is fitted on the sliding rod 25. The top of the inverted L-shaped anti-collision plate 21 slides on a sliding rod 28 in the top groove of the protective housing 1 via the connecting rod 27. A third spring 29, connected to the inner wall of the groove and the connecting rod 27, is fitted on the sliding rod 28. When an external object impacts... When the inverted L-shaped anti-collision plate 21 reaches both sides of the protective housing 1, it will be subjected to compressive force and slide along the slide bar, thereby compressing the second spring 26 and the third spring 29. The inverted L-shaped anti-collision plate 21 compresses the limiting rod 23, causing the limiting rod 23 to move within the buffer cylinder 22 and compress the first spring 24. As the first spring 24, the second spring 26, and the third spring 29 are compressed and buffered, the inverted L-shaped anti-collision plate 21 has a buffering force to protect the protective housing 1, thereby protecting the protector 3.

[0017] To prevent staff from accidentally touching the switch, limit grooves 31 are provided on both sides of the front end face of the protector 3. The protective cover 4 slides on the limit grooves 31 via the limit slider 32. The bottom of the protective cover 4 is connected to a plug rod 41. The bottom of the protector 3 is provided with a fixing seat 33. The bottom of the protective cover 4 is inserted into the fixing hole 34 of the fixing seat 33 via the plug rod 41. When the switch is turned on or off, the protective cover 4 is slid upward on the limit grooves 31 via the limit slider 32 to open, thereby realizing the adjustment of the switch.

[0018] Specifically, a cooling fan 5 is installed on the back of the protective housing 1, and heat dissipation holes 11 are provided on the lower ends of both ends of the protective housing 1; an operating door 12 is rotatably connected to the protective housing 1, and a transparent observation window is provided on the operating door 12; when heat dissipation is required, the cooling fan 5 is activated in conjunction with the heat dissipation holes to dissipate heat inside the protective housing 1.

[0019] Specifically, the protective cover 4 is installed around the protective switch on the protector 3.

[0020] The working principle and usage process of this utility model: When using this utility model, the operator installs the protector 3 inside the protective housing 1 through the snap-fit ​​seat 13. The protective cover 4, which is slidably set on the protector 3, has a protective effect on the switch during use, preventing the operator from accidentally touching the switch and causing the protector to close and become unusable.

[0021] The bottom and inner top of the inverted L-shaped anti-collision plate 21 are slidably connected to the bottom and top of the protective housing 1 via connecting rods 27. The inner sidewall of the inverted L-shaped anti-collision plate 21 is limited and slidably within the limiting buffer cylinders 22 on both sides of the outer wall of the protective housing 1 by limiting rods 23. When something from the outside collides with the sides of the protective housing 1, the inverted L-shaped anti-collision plate 21 will be subjected to compressive force and slide along the sliding rod, thereby compressing the second spring 26 and the third spring 29. The inverted L-shaped anti-collision plate 21 compresses the limiting rods 23, causing the limiting rods 23 to move within the buffer cylinders 22 and compress the first spring 24. As the first spring 24, the second spring 26, and the third spring 29 are compressed and buffered, the inverted L-shaped anti-collision plate 21 has a buffering force to protect the protective housing 1, thereby protecting the protector 3. The added buffer anti-collision structure 2 can protect the protective housing 1, reduce the probability of damage to the protector 3 caused by external impact force, and improve the service life of the device.

[0022] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
