[0032] See also Figure 1 The present application provides a control cabinet 10, which is used to realize intelligent control of high-power devices. Specifically, the control cabinet 10 includes a housing 100, a flow guide 200, a connecting structure 300, a first fixing member 400, a second fixing member 500 and a supporting member 600. The housing 100 is used to store and protect the flow guide 200, the connecting structure 300, the first fixing member 400, the second fixing member 500 and the supporting member 600. The flow guide 200 is used to guide the electrical components in the control cabinet 10. The connecting structure 300 is used to realize the insulating connection between the flow guide 200 and the supporting member 600. The first fixing member 400 cooperates with the connecting structure 300 to realize the fixing of the connecting structure 300 and the flow guide 200. The second fixing member 500 cooperates with the connecting structure 300 and the supporting member 600 to realize the fixing of the connecting structure 300 and the supporting member 600. It can be understood that the guide member 200 can be a copper sheet, iron sheet, etc. with better conductive properties, the support member 600 can be a sheet metal plate, iron plate, etc. with better supporting properties, and the first fixing member 400 and the second fixing member 500 can both be bolts, clips, etc.

[0033] Please also read Figure 2 , Figure 3 and Figure 4The connection structure 300 includes an insulating connector 310 and a matching member 320. The insulating connector 310 is insulated and connected between the guide 200 and the support 600. The matching member 320 is used to cooperate with the first fixing member 400 to fix the guide 200 on the insulating connector 310. Specifically, the insulating connector 310 includes an insulating first connecting portion 311. The first connecting portion 311 has a first connecting surface 3112 and a second connecting surface 3114 for carrying the guide 200. The first connecting surface 3112 is opposite to the second connecting surface 3114 and is arranged at a distance. The first connecting surface 3112 is recessed in a direction toward the second connecting surface 3114 to form a groove 3116. The matching member 320 is arranged in the groove 3116. The matching member 320 is used to cooperate with the first fixing member 400 to fix the insulating connector 310 and the guide 200. The support member 600 is located on a side of the first connection portion 311 facing away from the flow guide member 200 , and is insulatedly connected to the flow guide member 200 via the connection structure 300 .

[0034] In the conventional control cabinet 10, in order to facilitate the assembly of the matching piece 320 and the first fixing piece 400, it is usually necessary to reserve a large assembly space in the housing 100, so as to facilitate the use of hands or tools to fix the matching piece 320 during the assembly process. In this way, the volume of the control cabinet 10 is large and the difficulty of disassembly and assembly is increased. In the present application, by pre-installing the matching piece 320 in the groove 3116, without using hands or tools to hold the matching piece 320 tightly, the first fixing piece 400 can be directly driven into the matching piece 320 to achieve the cooperation between the first fixing piece 400 and the matching piece 320, so as to fix the flow guide 200 on the insulating connector 310. Specifically, the flow guide 200 is arranged on the second connecting surface 3114, and in the process of driving the first fixing piece 400 into the matching piece 320, the first fixing piece 400 is sequentially penetrated through the flow guide 200, the first connecting portion 311 and the matching piece 320 and cooperates with the matching piece 320. By providing the above-mentioned connection structure 300, it is not necessary to reserve assembly space for hands and tools, so that the volume of the control cabinet 10 can be effectively reduced, and the control cabinet 10 can be miniaturized. Moreover, in the process of fixing and tightening the matching piece 320 and the first fixing piece 400, since it is not necessary to use hands or tools to fix the matching piece 320, the convenience of assembling the guide piece 200 and the connection structure 300 can also be improved.

[0035] In addition, in the conventional control cabinet 10, after the first fixing member 400 is matched with the matching member 320, the matching member 320 is also easy to loosen and has a tendency to withdraw from the first fixing member 400 in a direction opposite to the driving direction of the first fixing member 400. For example, assuming that the first fixing member 400 is inserted from right to left and sequentially penetrates the first connecting portion 311 and the matching member 320 and matches with the matching member 320, the matching member 320 has a tendency to withdraw from the first fixing member 400 from left to right. In the present application, since the matching member 320 is arranged in the groove 3116, the groove wall of the groove 3116 can resist the matching member 320 in the circumferential direction of the matching member 320 and in the direction opposite to the driving direction, so that the matching member 320 is not easy to loosen, thereby effectively improving the installation reliability of the guide member 200 and the insulating connector 310.

[0036] Optionally, the first fixing member 400 may be a bolt, and the fitting member 320 may be a nut, or the first fixing member 400 may be a male buckle, and the fitting member 320 may also be a female buckle. In one embodiment, the first fixing member 400 is a connecting bolt, and the fitting member 320 is a connecting nut. Specifically, the connecting nut is a hexagonal nut of the M8 model, and correspondingly, the bolt is a bolt of the M8 model. By setting the first fixing member 400 as a connecting bolt and the fitting member 320 as a connecting nut, on the one hand, the production cost of the control cabinet 10 can be effectively reduced, and on the other hand, the deflector 200 and the insulating connector 310 can be detachably connected. When the deflector 200 or the insulating connector 310 is damaged, the deflector 200 or the insulating connector 310 can be replaced by removing the connecting bolt.

[0037] Specifically, the connecting bolts and the connecting nuts can be made of metal, plastic or other materials, and the manufacturing materials of the connecting bolts and the connecting nuts are not specifically limited here.

[0038] In one embodiment, a first assembly hole 3118 is provided on the first connection portion 311, which passes through the bottom of the groove 3116 and the second connection surface 3114, and the first assembly hole 3118 is aligned with the position of the matching piece 320. Specifically, taking the matching piece 320 as a connection nut and the first fixing piece 400 as a connection bolt as an example, a connection threaded hole is provided in the middle of the connection nut, the first assembly hole 3118 passes through the second connection surface 3114 and the bottom of the groove 3116 and is aligned and connected with the connection threaded hole, and the first fixing piece 400 is penetrated through the first assembly hole 3118 and the connection threaded hole, and is screwed with the connection nut. By pre-opening the first assembly hole 3118 on the first connection portion 311, it is not only convenient for the first fixing piece 400 to quickly find the assembly position, but also the first fixing piece 400 can be positioned during the process of driving the first fixing piece 400 and the first fixing piece 400 is subjected to less assembly resistance, so that the assembly of the first fixing piece 400 and the matching piece 320 is simpler and more labor-saving.

[0039] In one embodiment, the connection structure 300 further includes a first gasket (not shown) and a second gasket (not shown), the first gasket is clamped between the matching piece 320 and the bottom of the groove 3116, and the second gasket is arranged on the second connection surface 3114 and aligned with the first gasket. Specifically, the first gasket and the second gasket are both annular structures, and the two opposite end surfaces of the first gasket and the two opposite end surfaces of the second gasket are both smooth planes, and the first gasket is provided with a first avoidance hole, and the second gasket is provided with a second avoidance hole. In the process of cooperating with the matching piece 320, the first fixing piece 400 is sequentially passed through the guide piece 200, the second avoidance hole of the second gasket, the first connecting portion 311, and the first avoidance hole of the first gasket, and then cooperates with the matching piece 320. By providing the first cushion and the second cushion, the force bearing area between the first fixing member 400 and the first connecting portion 311 can be increased to prevent the first fixing member 400 from applying excessive pressure to the first connecting portion 311 and damaging the first connecting portion 311 during the mating process of the mating member 320. Optionally, the first cushion and the second cushion can be made of iron sheets, copper sheets or other materials with greater mechanical support strength.

[0040] Furthermore, in one embodiment, the connection structure 300 further includes an elastic pad (not shown), which is arranged on the side of the second pad facing away from the second connection surface 3114. Specifically, the elastic pad is also an annular structure, and an elastic avoidance hole is opened in the middle of the elastic pad. In the process of cooperating with the matching member 320, the first fixing member 400 passes through the guide member 200, the elastic avoidance hole of the elastic pad, the second avoidance hole of the second pad, the first connecting portion 311, and the first avoidance hole of the first pad in sequence, and then cooperates with the matching member 320. In the process of the first fixing member 400 contacting with the elastic pad, the elastic pad is deformed, so that the surface area of ​​the elastic member contacting with the first fixing member 400 increases, and then the friction between the first fixing member 400 and the first connecting portion 311 also increases, so that the first fixing member 400 and the first connecting portion 311 can be in more stable contact, so as to prevent the first fixing member 400 from falling off from the first connecting portion 311.

[0041] Please also read Figure 5In one embodiment, the insulating connector 310 further includes a second connector 312 insulated and connected between the support 600 and the first connector 311. The second connector 312 is provided to effectively prevent the current on the guide 200 from being conducted to the support 600 and causing a safety accident. Specifically, the first connector 311 is fixedly installed with the guide 200, and the second connector 312 is fixedly installed with the support 600. By providing the first connector 311 and the second connector 312, it is convenient to distinguish the areas on the insulating connector 310 that are respectively installed with the guide 200 and the support 600, so that the insulating connector 310, the guide 200 and the support 600 can be quickly and accurately installed. Moreover, the provision of the first connector 311 and the second connector 312 can also increase the distance between the guide 200 and the support 600 to prevent the guide 200 from leaking electricity.

[0042] In the control cabinet 10 , the control cabinet 10 further includes a second fixing member 500 , which is passed through the second connecting portion 312 and the supporting member 600 to connect the second connecting portion 312 and the supporting member 600 , thereby enabling the guide member 200 to be fixed on the supporting member 600 .

[0043] In one embodiment, the support member 600 includes a support body 610 and a connection unit (not shown) installed on the support body 610. The second fixing member 500 is sequentially arranged on the second connection portion 312 and the support body 610, and cooperates with the connection unit to achieve the fixation of the second connection portion 312 and the support body 610. Optionally, the second fixing member 500 can be a fixing bolt, and the connection unit can be a fixing nut. Specifically, the support body 610 is made of a sheet metal plate with better supporting performance, and the fixing nut and the fixing bolt are also metal components. The fixing nut can be pre-welded on the support member 600. In the process of assembling the fixing bolt and the fixing nut, the required assembly space is also small, so the volume of the control cabinet 10 can be further reduced, which is convenient for realizing the miniaturization of the control cabinet 10.

[0044] Furthermore, in one embodiment, the connection unit is disposed on the side of the support body 610 facing away from the second connection portion 312 to prevent the fixing bolt and the fixing nut from loosening. Specifically, during the process of the second fixing member 500 cooperating with the connection unit, the second fixing member 500 is sequentially passed through the second connection portion 312, the support body 610 and the connection unit and cooperates with the connection unit, and the second fixing member 500 also has a boss that can abut against the side of the second connection portion 312 facing away from the support body 610, so that the support body 610 and the second connection portion 312 can be clamped between the second fixing member 500 and the connection unit, so that the connection between the second connection portion 312 and the support body 610 is tighter and the installation is more reliable.

[0045] In one embodiment, the insulating connector 310 further includes an insulating bridge connection portion 313, and the opposite ends of the bridge connection portion 313 are respectively connected to the first connection portion 311 and the second connection portion 312 to form a Z-shaped insulating connector 310. Since the guide member 200 and the support member 600 are both metal components, if the distance between the guide member 200 and the support member 600 is small, when the power of the control cabinet 10 is large, the support member 600 may be charged due to being close to the guide member 200, thereby causing a serious safety accident. In the present application, by providing an insulating bridge connection portion 313, and the bridge connection portion 313 is connected with the first connection portion 311 and the second connection portion 312 to form a Z-shaped insulating connector 310, the installation distance between the first connection portion 311 and the second connection portion 312 can be increased, and the longitudinal installation distance between the guide member 200 and the support member 600 can be increased, so that the electrical spacing between the guide member 200 and the support member 600 is met in the longitudinal direction, so as to improve the safety performance of the control cabinet 10. It can be understood that the longitudinal direction is the connection direction between the guide member 200 and the support member 600 .

[0046] In one embodiment, the second connection part 312 is provided with a second assembly hole 3121 through which the second fixing member 500 can be inserted. The second assembly hole 3121 is aligned with the connection unit position. Specifically, taking the connection unit as a fixing nut and the second fixing member 500 as a fixing bolt as an example, a fixing threaded hole is provided in the middle of the fixing nut, the second assembly hole 3121 passes through the second connection part 312 and is aligned and connected with the fixing threaded hole, and the second fixing member 500 is inserted into the second assembly hole 3121 and the fixing threaded hole, and is screwed with the fixing nut. By pre-opening the second assembly hole 3121 on the second connection part 312, it is not only convenient for the second fixing member 500 to quickly find the assembly position, but also the second fixing member 500 can be positioned during the process of the second fixing member 500 being driven into the second connection part 312 and the second fixing member 500 is subjected to less assembly resistance, so that the assembly of the second fixing member 500 and the matching member 320 is simpler and more labor-saving.

[0047] Furthermore, in one embodiment, the groove 3116 and the second assembly hole 3121 are respectively disposed at ends of the first connection portion 311 and the second connection portion 312 that are away from each other. Since the first fixing member 400 and the second fixing member 500 are both made of metal materials, the first fixing member 400 and the second fixing member 500 are both conductive. If the first fixing member 400 and the second fixing member 500 are close to each other, the current on the guide member 200 may be transferred to the second fixing member 500 through the first fixing member 400, thereby causing a leakage accident. In the present application, by respectively arranging the groove 3116 and the second assembly hole 3121 at one end of the first connection part 311 and the second connection part 312 away from each other, when the first fixing member 400 is passed through the first connection part 311 and cooperates with the matching member 320, and the second fixing member 500 is passed through the second connection part 312 and cooperates with the connection unit, the first fixing member 400 and the second fixing member 500 have a large safety distance in the transverse direction perpendicular to the longitudinal direction, so that the first fixing member 400 and the second fixing member 500 can meet the electrical spacing requirements in the transverse direction to prevent leakage of the guide member 200.

[0048] Optionally, the first connection part 311, the second connection part 312 and the bridge connection part 313 can be formed separately or integrally. Preferably, the first connection part 311, the second connection part 312 and the bridge connection part 313 are integrally formed, so that the connection difficulty between the first connection part 311, the second connection part 312 and the bridge connection part 313 can be reduced, which is convenient for improving the manufacturing cost of the control cabinet 10.

[0049] Optionally, the insulating connector 310 can be made of insulating materials such as plastic, glass, and cardboard. In one embodiment, the insulating connector 310 is bakelite. Bakelite has good insulation and high mechanical strength, and can better support the guide member 200 on the support member 600, and achieve better insulation between the guide member 200 and the support member 600.

[0050] The above-mentioned connection structure 300 and the control cabinet 10 provided with the connection structure 300 can realize the fixation of the first fixing member 400 and the matching member 320 by pre-installing the matching member 320 in the groove 3116 and directly driving part of the first fixing member 400 into the matching member 320, thereby fixing the flow guide member 200 on the insulating connection member 310. In the process of driving the first fixing member 400 into the matching member 320, since the matching member 320 is pre-installed in the groove 3116, the matching member 320 can be fixed without using hands or tools to hold the matching member 320, thus effectively reducing the assembly space required for assembling the first fixing member 400 and the matching member 320, so as to reduce the volume of the control cabinet 10 and realize the miniaturization of the control cabinet 10.

[0051] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
