[0026] In order to make the technical solutions and beneficial effects of the present application more obvious and understandable, the technical solutions in the embodiments of the present application are clearly and completely described below by listing specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] It should be noted that the terms "first", "second", etc. used in this application can be used to describe various elements in this article, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element, rather than to describe a specific order or sequence.

[0029] The present application embodiment provides a cover plate for an electrical device, please refer to Figure 2 to Figure 5 , including a body 10 and a shielding cover 11 protruding from the body 10. The cover of the electrical equipment is used to close the housing of the electrical equipment, and can be a side plate, a top plate, a bottom plate or a back plate, and the present application has no limitation on this. The body 10 is roughly rectangular, and a reinforcing rib (not shown in the figure) is provided on the back thereof to enhance the mechanical strength of the cover.

[0030] The shielding cover 11 is arranged opposite to the wiring terminals of the electrical device 20 and is configured to shield the wiring terminals. The shielding cover 11 is arranged on the upper part of the body 10. The lower part of the body 10 is a relatively flat plate structure. The setting position of the shielding cover 11 on the body is adjusted according to the position of the wiring terminals. The embodiment of the present application provides a situation where the shielding cover 11 is arranged at one end of the body. It can be understood that the shielding cover 11 can also be arranged at other positions such as the middle part and the lower part of the body.

[0031] The shielding cover 11 includes an end face 13 and a plurality of side walls arranged around the end face 13. The end face 13 is parallel to the body. The plurality of side walls extend to the body 10. In the embodiment of the present application, the number of the plurality of side walls is four, including: a first side wall 4, a second side wall 12, a third side wall 14 and a fourth side wall 15. Figures 2-3 As shown, the first side wall 4 is the bottom wall, the second side wall 12 is the left side wall, the third side wall 14 is the top wall, and the fourth side wall 15 is the right side wall. The angle between the multiple side walls and the body is greater than or equal to 90 degrees. Figure 2 As shown, the first side wall 4 is tilted relative to the body 10, and the angle between the first side wall 4 and the body 10 is greater than 90 degrees to accommodate large terminals. The lower part of the body and the shielding cover 11 are smoothly transitioned through the first side wall 4. Optionally, the second side wall 12 is also tilted relative to the body 10.

[0032] It is understandable that the number of the side walls may be three, five or even more, depending on the needs.

[0033] The end surface 13 includes a first opening 9. At least one side wall adjacent to the end surface is provided with a second opening 16. Figure 3 As shown, the fourth side wall 15 adjacent to the end face 13 is provided with a second opening 16. The first opening 9 extends to the second opening 16 and communicates with the second opening 16. The end face 13 also includes a wire collection port 1, which is communicated with the first opening 9, and the wire collection port 1 is configured to receive a wire harness connected to the terminal block. The shape of the wire collection port 1 can be rectangular, trapezoidal or arc-shaped, etc., as long as it can receive the wire harness, and there is no limitation on this. Figure 2 It shows the situation that the first opening 9 and the cable collection port 1 are both rectangular, and the two are connected to form the shape of the letter "G". Figure 4 The case where the wire collection port 1 is arc-shaped is shown. The width of the first opening 9 and the wire collection port 1 can be different, as long as there is a connecting path between the two to facilitate the transfer of the wire harness between the two. For example, the width of the first opening 9 connecting with the wire collection port 1 is less than the maximum width of the wire collection port 1.

[0034] A grid 3 is provided on the outside of the body 10, which is configured to enhance the strength of the body 10 and also serves as a decoration. The outside of the body 10 is the side facing the user. The grid 3 can be linear or lattice-shaped, etc. Two mounting structures 5 and 6 are provided on the top edge of the end face 13, which are configured to fix the shielding cover 11 to the housing 20 of the electrical device. Two mounting structures 7 and 8 are provided on the bottom edge of the body 10. The number of mounting structures can be increased as needed. The mounting structure includes threaded holes, studs, or screws, etc. The cover body 10 is fixed to the housing 20 of the electrical device through the mounting structure.

[0035] The body also includes at least one opening 2, which is arranged opposite to the switch of the electrical device. The switch can be a knob switch or a key switch. Figure 5As shown, the knob switch is, for example, a photovoltaic knob switch. The number and position of the openings are adjusted according to the number and position of the switches.

[0036] When the conventional cover is used for wiring, since the terminal at one end of the wire harness that is connected to the wiring terminal on the device is relatively large, the wire harness or cable must first be passed through the cover, connected to the wiring terminal on the device, and then the cover must be installed on the housing 20. When a wiring error is found or maintenance is required, the cover must first be removed from the housing 20, and then the wires must be removed, which is cumbersome and inefficient.

[0037] When the electrical equipment cover plate of the embodiment of the present application is used, the installer first fixes the cover plate on the electrical equipment housing 20, and then connects the wire harness or cable to the terminal block. After installation, the wire harness or cable is placed in the wire collection port for storage, so that the plug-in cables are uniformly routed and the cable storage is convenient. When the wires need to be removed, the wire harness or cable is directly removed from the terminal block without removing the cover plate.

[0038] The present application also provides an electrical equipment housing, Figure 6 , comprising a housing 20 and an electrical device cover according to any one of the above embodiments, wherein the electrical device cover is fixed to the housing 20.

[0039] The embodiment of the present application also provides an electrical device, including the electrical device housing of the above embodiment. The electrical device may be an energy storage device or a photovoltaic device, including an inverter, a converter, a high-voltage box, an integrated energy storage device or an integrated photovoltaic storage device. The integrated energy storage device may be a household integrated energy storage device or a split device.

[0040] Optionally, the electrical equipment housing includes an energy storage equipment housing.

[0041] Optionally, the above-mentioned electrical equipment includes an energy storage device.

[0042] The electrical equipment cover, electrical equipment housing and electrical equipment of the embodiment of the present application adopt a non-enclosed opening, which makes it easy to disassemble and assemble the wiring harness, thereby improving the flexibility and work efficiency of installation. The cable collection port connected to the opening facilitates the storage of cables after they are concentrated and discharged.
