Description
Technical Field
[0001] The utility model belongs to the technical field of photovoltaic inverters, and more specifically, it relates to a flip-out wire cover of an inverter. Background Art
[0002] With the wide application of photovoltaic inverters in outdoor complex environments, the protection performance and operation convenience of their internal electronic components have become key design considerations. In the traditional inverter design, after the display control device is separated from the main body box, the wiring opening is often in an open state, resulting in easy intrusion of external dust, moisture, and foreign objects into the main body through the exposed cable channel. Under long-term operation, the accumulation of pollutants will cause problems such as circuit board corrosion and decreased insulation performance, seriously affecting the service life of the equipment. Especially in harsh working conditions such as high dust and salt spray, the equipment failure rate caused by such structural defects increases significantly.
[0003] In the prior art, a fixed protective cover is usually used to seal the wiring opening. However, this solution has significant limitations: during equipment debugging or maintenance, the cover needs to be repeatedly disassembled, which not only increases the operation complexity, but also easily causes wear of the threaded connectors due to frequent disassembly and assembly, reducing the sealing reliability; at the same time, after the fixed cover is opened, it cannot provide a stable cable guiding space, and the disordered arrangement of the wire harnesses is likely to cause stress concentration at the interfaces, posing a risk of connection loosening. Some improved solutions attempt to use a sliding rail shielding structure, but it is still difficult to balance the sealing performance and operation convenience, especially in a narrow installation space, it is difficult to achieve quick one-handed operation.
[0004] Therefore, the utility model provides a flip-out wire cover of an inverter. Summary of the Utility Model

[0032] The present utility model provides a flip - type wire outlet cover for an inverter. Please refer to Figures 1 to 6 as shown in the figure, which includes an inverter main body box 100, a terminal cover 200, and a display control device. The display control device is used to control the inverter. The inverter main body box 100 is connected to the terminal cover 200. An installation groove 210 is provided at the middle position outside the terminal cover 200. The installation groove 210 extends along the length direction of the terminal cover 200.

The display control device is wired - connected to the components in the inverter main body box 100 through the wiring opening 220. An outlet cover 300 is provided at the wiring opening 220. The outlet cover 300 is rotatably connected to the terminal cover 200. By flipping the outlet cover 300, the wiring opening 220 can be opened or closed. The terminal cover 200 and the inverter main body box 100 are detachably connected.
[0033] The cross - section of the wiring opening 220 is L - shaped. The outlet cover 300 fits with the wiring opening 220, and the cross - section of the outlet cover 300 is also L - shaped. The outlet cover 300 includes a first flat end face 310 and a second flat end face 320 that are connected to each other. Bending and flipping parts 330 are provided on both sides of the outlet cover 300. Through holes are provided at the centers of the bending and flipping parts 330. A first rectangular notch 311 is provided on the first flat end face 310, and a second rectangular notch 321 is provided on the second flat end face 320. After the first flat end face 310 and the second flat end face 320 of the outlet cover 300 fit with the wiring opening 220, two vertical dust - proof barriers are formed.

Through holes are formed at the centers of the flipping connection parts 230. The through holes of the bending and flipping part 330 and the through holes of the flipping connection parts 230 are rotationally connected. In this embodiment, the through holes of the bending and flipping part 330 and the through holes of the flipping connection parts 230 are rotationally connected by rivets;
[0035] On the inner wall of the bottom of the installation groove 210 of the terminal cover 200, a first limiting protrusion 240 in the shape of a rounded rectangle is provided at the edge of the wiring opening 220. On the inner wall of the side of the installation groove 210 of the terminal cover 200, a second limiting protrusion 250 in the shape of a rounded rectangle is provided at the edge of the wiring opening 220. The second limiting protrusion 250 corresponds to a second rectangular notch 321 formed on the second flat end face 320; when the terminal cover 200 and the wire outlet cover 300 close the wiring opening 220, the first limiting protrusion 240 is in limiting abutment with the first flat end face 310 of the wire outlet cover 300, so that the wire outlet cover 300 can only be flipped unidirectionally; when the terminal cover 200 and the wire outlet cover 300 open the wiring opening 220, the second rectangular notch 321 passes through the second limiting protrusion 250, and the second limiting protrusion 250 is in limiting abutment with the first flat end face 310 of the wire outlet cover 300, so that the wire outlet cover 300 can only be flipped unidirectionally by 90°; the setting of the first rectangular notch 311 facilitates the manual reset of the wire outlet cover 300 to the closed state.
[0036] A lifting protrusion is extended on the first rectangular notch 311 formed on the first flat end face 310. The setting of the lifting protrusion makes it more convenient and quick for the wire outlet cover 300 to be manually reset to the closed state.
[0037] On the inner wall of the bottom of the terminal cover 200, a wire fixing buckle 260 for fixing the connecting wire through which the display control device is wiredly connected to the devices in the inverter main body box 100 through the wiring opening 220 is adhered; the setting of the wire fixing buckle 260 realizes the directional management of the cable.
[0038] A torsion spring is arranged on the rotating shaft for the rotational connection between the through holes of the wire outlet cover 300 and the through holes of the terminal cover 200. In this embodiment, the torsion spring is arranged on the rivet, and the pre-tightening force direction of the torsion spring is consistent with the closing direction of the wire outlet cover 300; the setting of the torsion spring realizes the non-powered automatic closing of the wire outlet cover 300 and ensures immediate sealing after the display control device is separated.
[0039] A trapezoidal sealing strip made of EPDM is provided between the edge of the wiring opening 220 at the bottom side of the installation groove 210 of the terminal cover 200 and the outlet cover 300. The trapezoidal sealing strip fills the L-shaped joint when the outlet cover 300 is closed, improving the overall sealing performance of the inverter.
[0040] The first heat dissipation hole 270 is provided on the terminal cover 200, and the second heat dissipation hole 110 is provided on the inverter main body case 100.
[0041] The first flat end face 310 and the second flat end face 320 of the outlet cover 300 are integrally formed. Fillets are provided at the end corners of the first flat end face 310 and the second flat end face 320, and fillets are also provided at the end corners of the bending and flipping portion 330.
