[0063] Please refer to Figure 1 and Figure 2 , Fig.10 , Fig.12, which is a preferred embodiment of the utility model, the power plug-in frame includes: a shell 100; a plurality of partitions 140, which are detachably installed in the shell 100, and a slot 400 is formed between two adjacent partitions 140; the slot 400 is used for slidingly installing a circuit breaker 20 and / or a dummy panel 30; a DC input copper busbar assembly 200, including a signal PCB board 230, and the signal PCB board 230 is installed at the rear of the slot 400; the signal PCB board 230 is provided with a first gold finger area 231 for adapting to a common circuit breaker 20 and a second gold finger area 232 for adapting to an intelligent circuit breaker 20.

[0064] The power plug-in frame is provided with a partition 140 and a dummy panel 30, so that the width of the slot 400 can adapt to common circuit breakers and intelligent circuit breakers of multiple brands and specifications. Because the positions of the signal terminals on the back of common circuit breakers of different brands are different, the sizes of the first gold finger area 231 and the second gold finger area 232 on the signal PCB board 230 that contact the PIN pins on the signal terminals of the circuit breaker 20 are increased. When circuit breakers 20 of different brands are inserted into the slot 400, the PIN pins can fall into the first gold finger area 231 and the second gold finger area 232 to ensure signal conduction.

[0065] In one embodiment of the present application, the power supply frame includes a housing 100, a DC input copper busbar assembly 200, a slot 400 and other structures. The following further describes each of the above components in detail.

[0066] like Figure 1 and Figure 2 As shown, the housing 100 includes an upper cover 110, a bottom housing 120 and a rear cover 130. The upper cover 110 and the bottom housing 120 are arranged opposite to each other, and the rear cover 130 is arranged at the rear of the power plug-in frame. The upper cover 110, the bottom housing 120 and the rear cover 130 are surrounded together to form a box-shaped housing 100.

[0067] like Figure 2 As shown, the DC input copper bar assembly 200 includes a positive copper bar 210, a negative copper bar 220 and a signal PCB board 230. The positive copper bar 210, the signal PCB board 230 and the negative copper bar 220 are arranged in the rear half of the housing 100, that is, installed at the rear of the slot 400, and arranged in order from top to bottom. The positive copper bar 210 and the negative copper bar 220 are respectively arranged on the upper and lower sides of the signal PCB board 230, and are arranged parallel to the signal PCB board 230.

[0068] like Figure 3As shown, a plurality of partitions 140 are detachably installed in the housing 100, and a slot 400 is formed between two adjacent partitions 140. The slot 400 is disposed at the front half of the housing 100, and the circuit breaker 20 and / or the dummy panel 30 are slidably installed in the slot 400.

[0069] Figure 4 and Figure 5 As shown, the partition 140 is in the shape of a rectangular plate as a whole. A second slot 141 is provided at the tail of the partition 140 for engaging with the positive copper bar 210 and / or the negative copper bar 220 of the DC input copper bar assembly 200 . Figure 4 and Figure 6 As shown, a first boss 142 and a second boss 143 are provided on the top or bottom of the partition 140 , wherein the first boss 142 is provided in the middle of the partition 140 , and the second boss 143 is provided at the end of the partition 140 away from the second slot 141 .

[0070] like Figure 6 As shown, the housing 100 is provided with a plurality of first slots 121, which are arranged along the width direction of the housing 100. The first boss 142 is detachably mounted in the first slot 121, and the second boss 143 is mounted on the edge of the upper cover 110 or the bottom shell 120.

[0071] After the partition 140 is installed on the shell 100, the positive copper bar 210 and / or the negative copper bar 220 are inserted into the second slot 141, and at the same time, the first boss 142 on the partition 140 is embedded in the first slot 121, and cooperates with the second boss 143 to be stuck on the edge of the upper cover 110 or the bottom shell 120, so that the partition 140 is limited and fixed.

[0072] like Figure 7 As shown, the housing 100 is provided with front card slots 122 and rear card slots 123 arranged along the depth direction of the power plug-in frame, and the front card slots 122 and rear card slots 123 are provided at positions corresponding to the slots 400. Fig.10 As shown, the circuit breaker 20 is provided with a buckle 21. After the circuit breaker 20 is installed in the slot 400, the buckle 21 is detachably mounted in the front slot 122 or the rear slot 123. The specific positions of the buckles 21 are slightly different for circuit breakers 20 of different brands and specifications. The buckles 21 of some circuit breakers 20 correspond to the front slot 122, and the buckles 21 of other circuit breakers 20 correspond to the rear slot 123. That is, the front slot 122 and the rear slot 123 can be used to be compatible with circuit breakers 20 of different brands and specifications, and meet the buckle locking requirements.

[0073] In another embodiment of the present application, Figure 8 and Fig. 9 As shown, the power plug-in frame further includes a dummy panel 30. Specifically, as Figure 8 As shown, the tail of the dummy panel 30 is provided with a third slot 31 for engaging with the positive copper bar 210 and / or the negative copper bar 220. In other embodiments of the present application, the dummy panel 30 is provided with a guide limit edge 32 for matching with the lower edge of the top surface of the circuit breaker 20. Fig. 9 As shown, after the dummy panel 30 is installed in the slot 400 , the positive copper bar 210 and the negative copper bar 220 of the DC input copper bar assembly 200 at the rear of the frame can be inserted into the third slot 31 of the dummy panel 30 .

[0074] like Fig.10 As shown, the power plug-in frame can realize one-to-one interchange of 63A ordinary circuit breakers of different brands at any position. The 63A ordinary circuit breakers of different brands have the same external dimensions and the position of the buckle 21. The difference is that the position of the signal terminal on the back is inconsistent. When these ordinary circuit breakers are interchanged, the partition 140 does not need to be removed. Just take out any ordinary circuit breaker that needs to be replaced, use the guide limit function of the partition 140, insert the newly replaced ordinary circuit breaker, and then use the front slot 122 and the rear slot 123 to be compatible with the function of the buckle 21 of ordinary circuit breakers of different brands. After interchange, the buckle locking requirements are met, and interchange is achieved in structural design.

[0075] like Fig.11 and Fig.12 As shown, the signal PCB board 230 is provided with a first gold finger area 231 for adapting to the common circuit breaker 20 and a second gold finger area 232 for adapting to the intelligent circuit breaker 20. Specifically, the width of the first gold finger area 231 is greater than the width of the signal PIN pin of the common circuit breaker 20 of different specifications and different brands. The width of the second gold finger area 232 is greater than the width of the signal PIN pin of the intelligent circuit breaker 20 of different specifications and different brands.

[0076] The signal PIN pins of 63A and 125A common circuit breakers of different brands share the first gold finger area 231 on the signal PCB board 230 ; the signal PIN pins of 63A and 125A intelligent circuit breakers share the second gold finger area 232 on the signal PCB board 230 .

[0077] Because the positions of the signal terminals on the back of ordinary circuit breakers of different brands are inconsistent, the size of the first gold finger area 231 that contacts the signal PIN pin of the ordinary circuit breaker is increased on the signal PCB board 230. When ordinary circuit breakers of different brands are inserted into the plug-in frame, the signal PCB board 230 at the rear of the plug-in frame is inserted into the signal terminal on the circuit breaker, and the PIN pins on the signal terminal can all fall into the first gold finger area 231, ensuring signal conduction and achieving interchangeability in electrical functions (such as Fig.11 and Fig.12 ).

[0078] like Fig.13 As shown, the power plug-in frame can also realize one-to-one interchange of 63A ordinary circuit breakers of different brands with 63A intelligent circuit breakers at any position. Compared with 63A intelligent circuit breakers of different brands, the width and height dimensions of ordinary circuit breakers of 63A are the same, but the length dimensions and the position of the buckle 21 are different. When these ordinary circuit breakers are interchanged with intelligent circuit breakers, the partition 140 does not need to be removed. It is only necessary to take out the circuit breaker 20 to be replaced, and use the guiding and limiting function of the partition 140 to insert the newly replaced circuit breaker 20, and then use the front card slot 122 to be compatible with the buckle 21 of the intelligent circuit breaker, and the rear card slot 123 to be compatible with the buckle 21 of the ordinary circuit breaker. After the ordinary circuit breaker and the intelligent circuit breaker are interchanged, the buckle locking requirements are met, and the interchange is realized in the structural design.

[0079] like Fig.14 As shown, in another embodiment of the present application, a groove 410 is provided on the housing 100, and the position of the groove 410 corresponds to the slot 400, and can be specifically provided in the middle of the slot 400. A convex rib 22 is provided on the circuit breaker 20, and the convex rib 22 is detachably clamped in the groove 410. When the intelligent circuit breaker is inserted, the convex rib 22 on the intelligent circuit breaker is clamped into the groove 410, and the groove 410 cooperates with the convex rib 22 on the circuit breaker 20 to provide guidance and limit for the installation of the intelligent circuit breaker.

[0080] like Fig.12 and Fig.15 As shown, the signal PIN pins of 63A and 125A ordinary circuit breakers of different brands share the first gold finger area 231 on the signal PCB board 230 ; the signal PIN pins of 63A and 125A intelligent circuit breakers share the second gold finger area 232 on the signal PCB board 230 .

[0081] The signal terminals of ordinary circuit breakers of different brands and the signal terminals of intelligent circuit breakers are located on different sides. In the design of the signal PCB board 230, the second gold finger area 232 corresponding to the intelligent circuit breaker can be separated from the first gold finger area 231 corresponding to the ordinary circuit breaker. When ordinary circuit breakers or intelligent circuit breakers of different brands are inserted into the frame, due to the guiding and limiting effect of the partition 140 or the groove 410, the PIN pins on the signal terminals can all fall into their respective PCB gold finger areas, thereby achieving interchangeability in electrical design.

[0082] like Fig.12 As shown, since the positions of the back signal terminals of ordinary circuit breakers 20 of different brands of 125A are inconsistent, the size of the first gold finger area 231 in contact with the signal PIN pin of the ordinary circuit breaker 20 is increased on the signal PCB board 230, that is, the width of the first gold finger area 231 adopts a redundant design. When ordinary circuit breakers 20 of different brands of 125A are inserted into the frame, the signal PCB board 230 at the rear of the frame is inserted into the signal terminal on the circuit breaker 20. Since the width of the first gold finger area 231 reserves extra space, the PIN pins on the signal terminal can all fall into the first gold finger area 231, ensuring signal conduction and achieving interchangeability in electrical functions.

[0083] like Fig.16 and Fig.17 As shown, the power plug-in frame can also realize the interchangeability of 63A ordinary circuit breakers of different brands with 125A ordinary circuit breakers of different brands. One 125A ordinary circuit breaker or one 125A intelligent circuit breaker can replace three 63A ordinary circuit breakers.

[0084] When swapping, Fig.16 As shown, remove the three 63A circuit breakers 20 that need to be replaced and the two middle partitions 140; Fig.17 As shown, at this time, three small slots 400 form one large slot 400, and then dummy panels 30 are installed next to the other two partitions 140, so that the width of the large slot 400 is reduced to match the width of a 125A common circuit breaker or a 125A intelligent circuit breaker. After installing two dummy panels 30, the width of the large slot 400 is reduced to match the width of the circuit breaker 20, and the intelligent circuit breaker 20 is installed using the dummy panels 30 as a guide limiter.

[0085] Replay Figure 8There are two third card slots 31 at the rear of the dummy panel 30. When it is installed in the plug-in frame, the positive copper bar 210 and the negative copper bar 220 of the DC input copper bar assembly 200 on the back of the plug-in frame are inserted into the third card slots 31 of the dummy panel 30. The guide limit edge 32 of the dummy panel 30 provides a guide and limit function for the installation of 125A ordinary circuit breakers and 125A intelligent circuit breakers of different brands. At the same time, the convex rib 22 on the top of the intelligent circuit breaker 20 can cooperate with the groove 410 of the slot 400 to provide a guide and limit function for the installation of the intelligent circuit breaker 20 (see Fig.14 ).

[0086] like Fig.18 As shown, the signal PIN pins of 63A and 125A common circuit breakers 20 of different brands share the first gold finger area 231 on the signal PCB board 230; the signal PIN pins of 63A and 125A intelligent circuit breakers share the second gold finger area 232 on the signal PCB board 230. After three 63A circuit breakers 20 are replaced with one 125A circuit breaker 20, the 125A common circuit breaker or the 125A intelligent circuit breaker is adapted to the middle position gold finger.

[0087] Different brands of 63A ordinary circuit breakers 20 or 63A intelligent circuit breakers 20 can be interchanged with the forward line terminal 40. Through the interchange, DC current input can be realized from the front of the plug-in frame, providing more DC current input options. One plug-in frame is equipped with one forward line terminal 40, and it is only placed on the left side of the plug-in frame. One forward line terminal 40 replaces three 63A ordinary circuit breakers 20 or three 63A intelligent circuit breakers 20. Fig.19 and Fig. 20 As shown, the three 63A common circuit breakers 20 or three 63A intelligent circuit breakers 20 on the left and the two partitions 140 in the middle are removed, and the three small slots 400 are now formed into one large slot 400, and the width of the large slot 400 is adapted to the front line terminal 40. The front line terminal 40 has no signal output terminal, and the signal PCB board 230 does not need a corresponding gold finger. It is only necessary to insert the positive copper bar 210 and the negative copper bar 220 on the back of the frame into the rear slot of the front line terminal 40.

[0088] like Figure 21-26 As shown, a power plug-in frame system includes a plurality of the above-mentioned power plug-in frames and a copper busbar connection assembly 50, wherein the power plug-in frames are stacked together, and the copper busbar connection assembly 50 is fixedly connected to the plurality of the power plug-in frames. Figure 21-23 As shown, the copper busbar connection assembly 50 is in the shape of a flat plate as a whole. The present application does not limit its specific shape, and multiple power supply frames can be fixedly connected. In one embodiment of the present application, Fig.24 As shown, the power supply frame system achieves system expansion by adding different copper busbar connection components 50 at the back. In another embodiment of the present application, Fig.25As shown, the power supply frame system is connected to the existing power supply system or the customer power supply system by adding a copper busbar connection component 50 to achieve system expansion. Fig.26 As shown, the power frame system achieves system expansion by adding a copper busbar connection component 50 and connecting it with the existing power system customer power system cable.

[0089] The power plug-in frame is compatible with 1U ordinary circuit breakers 20 of different brands and specifications and 1U intelligent circuit breakers 20 of different specifications, providing customers with different output power distribution solutions; the DC input distribution solution of the power plug-in frame is selectable. On the basis of the DC input at the rear of the plug-in frame, the front line terminal 40 is added to realize the DC input at the front of the plug-in frame by interchange with the 1U circuit breaker 20; the power plug-in frame system can realize system expansion and connection and expansion with the existing DC power supply system or the client's DC power supply system by adding different copper busbar connection components 50 at the back of the plug-in frame.

[0090] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
