Example

[0036] Reference Figures 1 to 4 In order to solve the technical problem that the chassis socket 2 is exposed to the outside and is easily damaged, the utility model provides a photovoltaic micro-inverter chassis, including: a chassis 1, a socket 2 and a protection mechanism 3. The socket 2 is arranged on the outer wall of one side of the chassis 1, and is used to connect the inverter device in the chassis 1 with the external cable to realize current transmission, and the number of the sockets 2 depends on the model of the inverter. A slide groove 11 is opened on the outer wall of one side of the chassis 1, and the slide groove 11 is located on both sides of the socket 2. The protection mechanism 3 is arranged on the outer wall of one side of the chassis 1, and the socket 2 is located inside the protection mechanism 3, which is used to protect the socket 2, and the number of the protection mechanisms 3 is equal to the number of the sockets 2.

[0037] Furthermore, the protection mechanism 3 includes: an upper box 31, a lower box 32 and a sealing plate 33. The upper box 31 is fixedly arranged on one side outer wall of the box body 1, and the upper box 31 is located above the socket 2. One end and the bottom of the upper box 31 are both open-shaped. The open-shaped design is used to provide a connection space for the cable and the socket 2 when separated from the lower box 32. In the process of connecting the cable and the socket 2, the cable and the socket 2 can also be protected by the upper box 31, so as to avoid rainwater splashing onto the cable and the socket 2, thereby achieving a protective effect when the socket 2 is connected to the cable. One end of the lower box 32 is slidably set in the slide groove 11, and the lower box 32 is located below the upper box 31. The top of the lower box 32 is open, and the design of the lower box 32 sliding in the slide groove 11 can realize the merging and separation of the upper box 31 and the lower box 32. In the merged state, the socket 2 is closed to achieve sealed protection for the socket 2. In the separated state, the socket 2 can be exposed to the outside, so that the socket 2 can be connected to the cable. The sealing plate 33 is fixedly arranged at the top of one end of the lower box 32, and the sealing plate 33 is plugged with the upper box 31, so that when the upper box 31 and the lower box 32 are merged, the sealing plate 33 and the upper box 31 are plugged to seal the opening of one end of the upper box 31, and the plugged connection relationship firmly connects the upper box 31 and the lower box 32 together (in order to facilitate the operator to separate the upper box 31 from the lower box 32, the outer wall of the sealing plate 33 is provided with a protrusion {not marked in the figure}), so that the socket 2 can be sealed and protected. The heat dissipation part 34 is arranged in the lower box 32, and is used to dissipate heat when the socket 2 is connected to the cable. In this embodiment, the socket 2 arranged on the outer wall of the box body 1 can be connected to the external cable, and the protection of the socket 2 can be achieved by arranging a protection mechanism 3 that wraps the socket 2 outside the socket 2, and the structural design that the upper box 31 and the lower box 32 in the protection mechanism 3 can be merged and disassembled can achieve the effect of fully protecting the socket 2.

[0038] In an optional embodiment, in order to prevent rainwater from flowing into the interior of the upper box 31 and the lower box 32 through the gap between them and affecting the cables and the socket 2, a first baffle 311 is fixedly provided on the top of the opening at one end of the upper box 31, and a second baffle 312 is fixedly provided on both sides of the upper box 31. The connecting surfaces of the upper box 31 and the lower box 32 are both provided with sealing rubber 321, wherein the baffle can prevent rainwater from sliding down, and the sealing rubber 321 pad is used to prevent rainwater from penetrating into the interior of the upper box 31 and the lower box 32 when the upper box 31 and the lower box 32 are combined.

[0039] Please refer to 2 to Figure 4As shown, in this embodiment, a first heat dissipation slot 12 and a second heat dissipation slot 13 are provided on one side outer wall of the box body 1, and the first heat dissipation slot 12 and the second heat dissipation slot 13 are sequentially located below the socket 2, wherein the first heat dissipation slot 12 is located above the second heat dissipation slot 13, and the first heat dissipation slot 12 is close to the socket 2. An inclined plate 14 is provided in the second heat dissipation slot 13, and the design of the inclined plate 14 is used to guide the direction of the air outlet of the second heat dissipation slot 13, wherein the inclined plate 14 is inclined downward, so the air outlet of the second heat dissipation slot 13 is inclined downward.

[0040] Furthermore, in this embodiment, the heat dissipation unit 34 includes: a heat dissipation fan 341 and a ventilation slot 342. The heat dissipation fan 341 is fixedly arranged on one side of the sealing plate 33. It should be separately explained that the position of the heat dissipation fan 341 can move with the movement of the lower box 32. Specifically, when the lower box 32 is separated from the upper plate (that is, when the socket 2 is connected to the cable), the position of the heat dissipation fan 341 is opposite to the first heat dissipation slot 12, and the wind blown by the heat dissipation fan 341 can dissipate the heat of the socket 2 located in the box body 1 through the first heat dissipation slot 12, thereby protecting the socket 2. The ventilation slot 342 is provided at the bottom of the lower box 32, and the ventilation slot 342 is located below the No. 2 heat dissipation slot 13, so that the No. 2 heat dissipation slot 13 is guided by the inclined plate 14 to guide the air outlet direction into the ventilation slot 342, so that the No. 2 heat dissipation slot 13 can guide the hot air inside the box 1 into the ventilation slot 342 and then discharge it to the outside, and form an air circulation system with the No. 1 heat dissipation slot 12 and the heat dissipation fan 341, thereby achieving the effect of protecting the socket 2. In this embodiment, the box 1 is provided with the No. 1 heat dissipation slot 12 and the No. 2 heat dissipation slot 13 below the socket 2 to dissipate heat when the socket 2 is connected to the cable, and the heat dissipation fan 341 and the ventilation slot 342 installed in the lower box 32 can form an air circulation system with the No. 1 heat dissipation slot 12 and the No. 2 heat dissipation slot 13, thereby achieving the protection of the socket 2 when it is connected, and achieving the effect of increasing the protection of the socket 2 by the device.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
