[0030] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0031] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0032] The switch assembly and power supply module provided in the embodiments of the present application are described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 to 6 An embodiment of the present application provides a switch assembly 10, which is applied to a power module 20. The power module 20 includes a box 21, an input port 23 is provided on the rear panel 22 of the box 21, an electrical module 24 is provided in the box 21, and an input terminal 241 of the electrical module 24 extends out of the box 21 from the input port 23; and the switch assembly 10 includes a fixing bracket 11, a switch body 12 fixed to one side of the fixing bracket 11, and a fuse 15 provided on the other side of the fixing bracket 11, wherein the fixing bracket 11 is detachably fixed to the rear panel 22 of the box 21, and the side of the fixing bracket 11 on which the fuse 15 is provided faces the box 21, so that the fuse 15 is located between the fixing bracket 11 and the rear panel 22 of the box 21. The input end of the fuse 15 is electrically connected to the output terminal of the switch body 12, and the output end of the fuse 15 is electrically connected to the input terminal 241 of the electrical module 24. The external power supply is connected through the input terminal of the switch body 12, and then output from the output terminal of the switch body 12 to the input end of the fuse 15 after passing through the switch body 12, and then output from the output end of the fuse 15 to the input terminal 241 of the electrical module 24 after passing through the fuse 15, thereby realizing the electrical connection between the external power supply and the electrical module 24 in the box 21 of the power module 20.

[0034] Therefore, the switch body 12 and the fuse 15 in this embodiment are modularly designed through the fixed bracket 11, and the fuse 15 is externally installed on the rear panel 22 outside the power box 21, which can reduce the occupation of the internal space of the power box 21, improve the space utilization of the whole machine, and reduce the size of the whole machine; and the fuse 15 is a wearing part, and after it is externalized, maintenance is more convenient, which greatly reduces the difficulty and cost of later maintenance; in addition, after the fuse 15 is externalized, the interference to the front-end input of the power supply can also be reduced.

[0035] In some embodiments, the switch assembly 10 optionally further includes a fuse input copper busbar 13, one end of which is electrically connected to the output terminal of the switch body 12, and the other end of which is electrically connected to the input terminal of the fuse 15. Because the switch body 12 and the fuse 15 are disposed on either side of the fixing bracket 11, the fuse input copper busbar 13 bends and extends from one side of the fixing bracket 11 to the other side of the fixing bracket 11.

[0036] In other embodiments, the switch assembly 10 optionally further includes a first insulating support column 16, one end of which is fixedly mounted on the fixing bracket 11, and the other end of which is fixedly connected to the fuse input copper busbar 13. Since the switch assembly 10 is used for a three-phase power supply, the number of fuse input copper busbars 13 can be three, and accordingly, the number of first insulating support columns 16 is also three. A first insulating support column 16 is disposed between each fuse input copper busbar 13 and the fixing bracket 11. The first insulating support column 16 not only serves to insulate between the fixing bracket 11 and the fuse input copper busbar 13, but also serves to support and secure the fuse input copper busbar 13. In an optional embodiment, the first insulating support column 16 is fastened to the fixing bracket 11 by screws.

[0037] In some embodiments, the switch assembly 10 optionally further includes a fuse output busbar 14, one end of which is electrically connected to the output end of the fuse 15, and the other end of which is electrically connected to the input terminal 241 of the electrical module 24. Similarly, since the switch assembly 10 is used for a three-phase power supply, the number of fuse input busbars 13 can be three. Since the input terminal 241 of the electrical module 24 extends from the input port 23 of the rear panel 22 of the housing 21, the fuse output busbar 14 can be directly connected to the output terminal of the electrical module 24 outside the housing 21, facilitating wiring between the two.

[0038] In other embodiments, the switch assembly 10 optionally further includes a second insulating support column 17, one end of which is fixedly mounted on the fixing bracket 11, and the other end is fixedly connected to the fuse output copper busbar 14. Since there are three fuse output copper busbars 14, there are also three second insulating support columns 17. One second insulating support column 17 is disposed between each fuse output copper busbar 14 and the fixing bracket 11. The second insulating support column 17 not only insulates the fixing bracket 11 from the fuse output copper busbar 14, but also supports and secures the fuse output copper busbar 14. In an optional embodiment, the second insulating support column 17 is attached to the fixing bracket 11 by screws.

[0039] In some embodiments, the switch assembly 10 further includes a limiting bracket 18, on which a limiting protrusion is provided. There are multiple fuse output copper bars 14, for example, 3 when a three-phase power supply is input, and the multiple fuse output copper bars 14 are arranged at intervals. The limiting bracket 18 is fixedly connected to the multiple fuse output copper bars 14, and the limiting protrusion is arranged between two adjacent fuse output copper bars 14, thereby preventing the multiple fuse output copper bars 14 from shaking in a direction perpendicular to the fuse output copper bar 14. In an optional embodiment, the limiting bracket 18 is locked and fixed to each fuse output copper bar 14 by a screw. When installing the switch assembly 10, the multiple fuse output copper bars 14 can be fixed first by using the limiting bracket 18, and then the fuse output copper bar 14 can be fixed to the second insulating support column 17, so as to facilitate installation and avoid shaking of the fuse output copper bar 14 during installation.

[0040] In other embodiments, the fixing bracket 11 may optionally be U-shaped, with flanges 111 formed on both sides of the U-shaped opening of the fixing bracket 11. Positioning holes 112 are formed on the flanges 111, and positioning pins corresponding to the positioning holes 112 are provided on the rear panel 22 of the box body 21. Thus, the fixing bracket 11 can be pre-placed on the rear panel 22 of the box body 21 by utilizing the positioning function of the positioning holes 112 and the positioning pins, and then the screws can be tightened to completely secure the fixing bracket 11 to the rear panel 22 of the box body 21, thereby facilitating the installation process.

[0041] During the actual assembly process, first install and fix the switch body 12 on one side of the fixing bracket 11, then lock the first insulating support column 16 and the second insulating support column 17 on the other side of the fixing bracket 11, insert the fuse input copper bar 13 so that one end is connected to the output terminal of the switch body 12, fix the fuse output copper bar 14 to the limit bracket 18, and then lock and fix the fuse output copper bar 14 to the second insulating support column 17, install the fuse 15, and fix one end of the fuse 15 to the output end of the fuse input copper bar 13. The other end of the fuse 15 is fixed to the input end of the fuse output copper busbar 14. At this time, the output end of the fuse input copper busbar 13 and the corresponding end of the fuse 15 are locked and fixed to the first insulating support column 16, and the input end of the fuse output copper busbar 14 and the corresponding end of the fuse 15 are also locked and fixed to the second insulating support column 17; thereafter, the assembled switch assembly 10 is inserted into the positioning pin of the rear panel 22 of the box body 21 through the positioning hole 112, and then the screws are tightened to achieve complete fixation between the switch assembly 10 and the rear panel 22 of the box body 21.

[0042] In some embodiments, the fixing bracket 11 optionally includes a first bracket and a second bracket, wherein the first bracket is detachably connected to the rear panel 22 of the housing 21, and the second bracket is disposed on a side of the first bracket facing away from the rear panel 22 of the housing 21. By dividing the fixing bracket 11 into two parts, the switch body 12 can be first fixed to the second bracket, facilitating operations such as screwing between the two. The second bracket can then be fixedly connected to the first bracket, and finally the first bracket can be fixed to the rear panel 22 of the housing 21. In one optional embodiment, both the first bracket and the second bracket are U-shaped.

[0043] In the embodiment of the present application, since the fuse 15 is a wearing part, installing the fuse 15 externally on the rear panel 22 can reduce the internal space occupied by the box 21, improve the space utilization of the whole machine, reduce the size of the whole machine, and facilitate later maintenance (the power supply module 20 is installed in the cabinet, and the fuse 15 is externally installed on the rear panel 22. The power supply module 20 does not need to be pulled out of the cabinet, and can be directly disassembled and maintained from the rear panel 22). At the same time, it can also reduce interference on the input front end.

[0044] In a second aspect, the present application further provides a power supply module 20, which includes a housing 21, an electrical module 24, and the switch assembly 10 of the above-described embodiment. An input port 23 is provided on the rear panel 22 of the housing 21. The electrical module 24 is disposed within the housing 21, and input terminals 241 of the electrical module 24 extend from the input port 23 on the rear panel 22 outside the housing 21 and connect to the switch assembly 10. The switch assembly 10 includes a fixing bracket 11, a switch body 12 fixedly disposed on one side of the fixing bracket 11, and a fuse 15 disposed on the other side of the fixing bracket 11. The fixing bracket 11 is detachably fixed to the rear panel 22 of the housing 21, with the side of the fixing bracket 11 on which the fuse 15 is disposed facing the housing 21. The input terminal of the fuse 15 is electrically connected to the output terminal of the switch body 12, and the output terminal of the fuse 15 is electrically connected to the input terminal 241 of the electrical module 24.

[0045] The switch component 10 in the power module 20 in this embodiment has the corresponding technical features in the above-mentioned switch component embodiments and can achieve the same technical effects. To avoid repetition, they will not be described here.

[0046] In some embodiments, the electrical module 24 optionally includes a filter and / or filtering circuit. That is, the external power is input via the switch assembly 10 to the filter and / or filtering circuit within the housing 21, which filters the input power signal. Because the fuse 15 is externally located outside the rear panel 22 of the housing 21, interference at the input front end can be reduced.
