DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] like Figure 1 and Figure 2As shown, to achieve the above-mentioned objectives, the present invention provides a switching power supply connection device, comprising: a switch box 1 and a mounting rail 2 provided on the inner side wall of the switch box 1. It should be noted that a plurality of heat dissipation holes are arranged in an array on two symmetrical side surfaces of the switch box 1. The heat dissipation holes arranged in opposite directions can accelerate air circulation within the switch box 1, thereby improving the heat dissipation efficiency of the switching power supply 3 and protecting the switching power supply 3.

[0029] Among them, a first assembly hole 101 is provided on the outside of the switch box 1, and a mounting guide rail 2 is provided at the position of the first assembly hole 101. The right end of the mounting guide rail 2 is connected to the inner wall of the switch box 1, and the mounting guide rail 2 is perpendicular to the inner wall of the switch box 1, that is, along the length direction of the mounting guide rail 2, the first assembly hole 101 coincides with the projection surface of the mounting guide rail 2, and the switching power supply 3 is installed in the mounting guide rail 2. When the switching power supply 3 needs to be installed, the switching power supply 3 is inserted into the mounting guide rail 2 through the first assembly hole 101, and further slides into the mounting guide rail 2 to complete the installation of the switching power supply 3.

[0030] A quick-plug device is provided in the switch box 1, and the quick-plug device includes: a socket bracket 4, which is connected to the inner wall of the switch box 1. A socket assembly 8 is provided on the socket bracket 4. The first end of the socket assembly 8 is connected to a plurality of terminal blocks 9. The second end of the socket assembly 8 is connected to the switching power supply 3. The terminal blocks 9 and the switching power supply 3 are connected together through the socket assembly 8, and then the switching power supply 3 is connected to the circuit.

[0031] During use, the switching power supply 3 is inserted into the designated position in the mounting guide rail 2 through the first assembly hole 101. One end of the switching power supply 3 is automatically connected to the socket assembly 8, and the switching power supply 3 is locked on the mounting guide rail 2, completing the installation of the switching power supply 3. When the switching power supply 3 is damaged and needs to be repaired, the switching power supply 3 is directly unplugged after the limit of the mounting guide rail 2 on the switching power supply 3 is released. Compared with the traditional installation method of the switching power supply 3, there is no need to remove the wires and then remove the switch box 1. The installation and removal of the switching power supply 3 are simpler, and quick plugging, replacement and maintenance can be achieved.

[0032] In one embodiment of the present invention, the upper end of the socket bracket 4 is connected to the left end of the mounting rail 2. Specifically, the lower end of the socket bracket 4 is fixed to the inner wall of the switch box 1 by a plurality of bolts, and the upper end of the socket bracket 4 is connected to the left end of the mounting rail 2 by a plurality of bolts, and cooperates with the right end of the mounting rail 2 to be connected to the inner wall of the switch box 1, so that the two ends of the mounting rail 2 are stably limited, thereby enabling it to be stably installed in the switch box 1.

[0033] Preferably, a plurality of plugs 302 are provided on the end surface of the switching power supply 3 near the socket bracket 4, and a plurality of plug connectors 5 are provided on the end of the socket assembly 8 near the switching power supply 3. Each plug connector 5 is connected to a terminal block 9. When the switching power supply 3 is located at a designated position within the mounting rail 2, each plug connector 5 is snap-connected to a plug 302. That is, when the switching power supply 3 is inserted into the designated position within the mounting rail 2, the plug 302 automatically connects to the corresponding plug connector 5, eliminating the need for separate wiring. When the switching power supply 3 is removed from the mounting rail 2, the plug 302 automatically disengages the plug connector 5, eliminating the need for separate wiring, thereby expediting the installation and removal of the switching power supply 3.

[0034] like Figure 3 As shown, the plug 302 and the plug connector 5 are both made of a metal material with good conductivity. Preferably, the plug 302 and the plug connector 5 are both made of copper sheet material. The plug connector 5 includes two elastic copper sheets symmetrically arranged on both sides of the plug 302. The tail ends of the two elastic copper sheets are integrally arranged and connected to the terminal 9. The plug 302 enters between the two elastic copper sheets. The two elastic copper sheets clamp the two ends of the plug 302 to complete the stable connection between the plug 302 and the plug connector 5.

[0035] A first mounting hole 303 is provided at one end of the plug 302 close to the switching power supply 3. A plurality of first screw holes are arranged in an array on the switching power supply 3. First screws pass through the first mounting holes 303 and connect to the first screw holes, thereby fixing the plug 302 to the switching power supply 3 and contacting the electrodes on the switching power supply 3. The above is the structural part of the switching power supply 3.

[0036] In addition, a through hole 402 is provided on the top surface of the socket bracket 4. The through hole 402 is generally in the shape of a strip. The connection status between the plug 302 and the plug connector 5 can be observed through the through hole 402. Moreover, the provision of the through hole 402 can save its manufacturing materials while ensuring the structural strength of the plug 302 bracket, thereby reducing the production cost of the overall connecting device.

[0037] It should be further explained that the mounting rail 2, the socket bracket 4, the plug 302 and the plug connector 5 are all made of sheet metal technology, which improves the assembly accuracy of the overall connection device while increasing material utilization and reducing production costs.

[0038] In one embodiment of the present invention, a second assembly hole 401 is provided on the side of the socket bracket 4, and the second assembly hole 401 is connected to the socket assembly 8. Specifically, fourth mounting holes are symmetrically provided on both sides of the second assembly hole 401, and a fifth mounting hole is correspondingly provided on the socket assembly 8. Bolts pass through the fourth mounting holes and the fifth mounting holes and cooperate with nuts to fix the socket assembly 8 on the socket bracket 4, wherein the socket assembly 8 is rectangular as a whole. The second assembly hole 401 is designed according to the structure of the socket assembly 8 to stably connect the socket assembly 8 in the second assembly hole 401. The socket assembly 8 is connected through the second assembly hole 401, which facilitates the later repair of the socket assembly 8 by disassembly and assembly after it is damaged.

[0039] In one embodiment of the present invention, the mounting rail 2 includes two symmetrically arranged rail frames 201. Specifically, the rail frames 201 are generally U-shaped, with the U-shaped opening facing the switching power supply 3. The switching power supply 3 enters the rail frames 201 through the first assembly hole 101. The inner side surfaces of the rail frames 201 abut the switching power supply 3, primarily securing the two sides of the switching power supply 3 rather than fully encasing the switching power supply 3. This allows the surface of the switching power supply 3 to be exposed to the air as directly as possible, facilitating heat dissipation from the switching power supply 3. Furthermore, the positions of the two rail frames 201 within the switch box 1 can be precisely adjusted according to the width of the switching power supply 3, allowing the two rail frames 201 to precisely secure the switching power supply 3. This allows the system to accommodate switching power supplies 3 of various sizes and models, broadening the applicability of the overall connection device.

[0040] In addition, a plurality of second mounting holes 202 are provided on the side of the guide rail frame 201, and a plurality of second screw holes 301 are provided on both sides of the switching power supply 3. When the switching power supply 3 enters the designated position in the guide rail frame 201, the switching power supply 3 is connected to the circuit. Each second mounting hole 202 corresponds coaxially to a second screw hole 301. A second screw is passed through the second mounting hole 202 and connected to the corresponding second screw hole 301 to fix the switching power supply 3 on the guide rail frame 201, thereby completing the position limiting of the multiple switching power supplies 3, preventing the switching power supply 3 from detaching from the guide rail frame 201 during use, and ensuring the stability of the switching power supply 3 connected to the circuit.

[0041] like Figure 4 As shown, the inner side surface of the guide rail frame 201 is provided with a plurality of limiting protrusions 203. Specifically, the plurality of limiting protrusions 203 are symmetrically arranged on the upper and lower sides of the guide rail frame 201. That is, the plurality of limiting protrusions 203 respectively abut the upper and lower sides of the switching power supply 3, so that the switching power supply 3 can be in a relatively static state relative to the guide rail frame 201, thereby protecting the switching power supply 3.

[0042] Preferably, a buffer pad (not shown in the figure) is provided on the bottom surface of the limiting protrusion 203, and the limiting protrusion 203 contacts the switching power supply 3 through the buffer pad. When the switch box 1 vibrates or collides, the buffer pad can play a certain buffering role, avoiding rigid contact between the switching power supply 3 and the guide rail frame 201, preventing the switching power supply 3 from being damaged or even ignited due to excessive local force, and improving safety.

[0043] In one embodiment of the present invention, a connecting foot 204 is integrally provided at one end of the guide rail frame 201, and the connecting foot 204 is connected to the switch box 1 by a bolt. A threaded hole is provided on the side of the connecting foot 204, and a plurality of third mounting holes are arranged in an array on the switch box 1. The bolts pass through the corresponding third mounting holes and connect the threaded holes to fix the right end of the mounting guide rail 2 on the switch box 1. At this time, the side of the connecting foot 204 fits the inner wall of the switch box 1, so that the length direction of the guide rail frame 201 is perpendicular to the inner wall of the switch box 1, thereby ensuring that the switching power supply 3 can smoothly enter the mounting guide rail 2 through the first assembly hole 101 and accurately dock with the socket assembly 8.

[0044] It should be noted that a positive power pole 6 and a negative power pole 7 are provided on the inside of the switch box 1. The positive power pole 6 and the negative power pole 7 are respectively connected to the corresponding terminal 9 through wires, and the positive power pole 6 and the negative power pole 7 are extended to the outside of the switch box 1. The switching power supply 3 is connected to the required electrical appliances through the positive power pole 6 and the negative power pole 7 to realize the discharge function.

[0045] When the present invention is used, the switching power supply 3 is inserted from the first assembly hole 101 into the designated position in the mounting rail 2. The left end of the switching power supply 3 is automatically connected to the socket assembly 8, that is, the plug 302 and the plug connector 5 are connected to each other. The switching power supply 3 is connected to the circuit. The second screw is passed through the second mounting hole 202 and connected to the corresponding second screw hole 301 to lock the switching power supply 3 on the mounting rail 2, completing the installation of the switching power supply 3. When the switching power supply 3 is damaged and needs repair, the second screw is removed to release the limit of the mounting rail 2 on the switching power supply 3. The switching power supply 3 is directly unplugged, and the plug 302 is automatically disengaged from the plug connector 5, completing the removal of the switching power supply 3.

[0046] In summary, by cooperating with the mounting rail 2 and the quick-insertion device, the switching power supply 3 is inserted into the mounting rail 2 from the first assembly hole 101, and the switching power supply 3 is automatically connected to the socket assembly 8, completing the installation of the switching power supply 3. When the switching power supply 3 needs to be disassembled, the switching power supply 3 is directly pulled out after the limit is released, without the need to remove the wires and then remove the switch box 1. The installation and disassembly of the switching power supply 3 are simpler, effectively solving the problem of inconvenient maintenance of the switching power supply 3.

[0047] In addition to the above-mentioned switching power supply connection device, the present invention also provides an energy storage cabinet including the switching power supply connection device disclosed in the above-mentioned embodiment.

[0048] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0049] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
