Such as the connection of dense bus bars in a data center in the prior art as shown in fig. 2. Compact buses include two types of buses: main road bus and branch road bus. The main road bus extends along the data center and is used as a main road for providing electric energy. The branch bus is used as a branch structure for supplying power to different devices. When the main circuit bus is connected with the branch circuit bus, the main circuit bus can be provided with a plug box with a switch, the branch circuit bus can also be provided with a head end box with a switch, the plug box and the head end box are connected through a cable, and the main circuit bus and the branch circuit bus are electrically communicated. The requirement of two switches in the above described power distribution circuit increases the point of failure on the circuit, increasing the likelihood of failure of the power distribution circuit. Therefore, the embodiment of the application provides the jack box for improving the connection effect of the main circuit bus and the branch circuit bus in the data center. The details of which are set forth in the accompanying drawings and the examples below.

The jack box 100 mainly includes a box body 20 and a switch unit 10 fixedly provided in the box body 20. The box 20 is used to connect the main bus bar 200 and the branch bus bar 300, respectively, and there is only one break point (where the box 20 is located) between the main bus bar 200 and the branch bus bar 300. The switching unit 10 is respectively connected with the main circuit bus 200 and the branch circuit bus 300, and when the switching unit 10 is closed, the main circuit bus 200 and the branch circuit bus 300 are conducted; when the switching unit 10 is opened, the main branch bus 200 and the branch bus 300 are disconnected.
Fig. 4 shows an internal structural schematic diagram of a jack box provided in an embodiment of the present application. The case 20 includes a cover 21, a first connection terminal 22, and a second connection terminal 27. The first connection terminal 22 is fixedly connected to the cover 21 and is used for connection to the main bus bar 200; the second connection terminal 27 is fixedly connected to the housing 21 and is used for connection to the branch bus bar 100.
The switching unit 10 is electrically conductively connected to the first connection terminal 22 via a first connector 24. Illustratively, the first connector 24 is connected with the first connection terminal 22 through the first copper bar 23. The first copper bar 23 is fixedly arranged in the outer cover 21 as an adapter. During the setting, the setting position of the first connector 24 can be adjusted by the length and shape of the first copper bar 23, so that the first connector 24 and the switch unit 10 can be conveniently connected correspondingly.

The first pin 241 is fixedly connected to the switch unit, and the first socket 242 is fixedly connected to the first copper bar. Similarly, the second connector has the same structure as the first connector, and is not described herein again.
When the switch unit is fixed in the case, the first pins 241 are inserted into the first sockets 242 one-to-one and are electrically connected; the second pins of the second connector are inserted into the second sockets in a one-to-one correspondence and are in conductive communication. When the switch unit needs to be taken out of the box body for replacement or maintenance, the first pins 241 are pulled out of the corresponding first sockets 242, and the second pins are pulled out of the corresponding second sockets, so that the circuit is disconnected.
It should be understood that the above-described pin and socket mating may take different forms, such as a quincunx socket and a quincunx pin mating, or a duckbill socket and a strip-shaped pin mating, and is not specifically limited in this application.
As can be seen from the above description, the circuit connection of the switch unit during the plug connection is realized by the cooperation of the first connector and the second connector. When the switch unit breaks down, can directly take out the switch unit from the box and maintain, need not to take off whole jack box to the degree of difficulty of maintenance has been reduced. In addition, when the switch unit is connected with the box body in a plugging and unplugging mode, when the switch unit is taken out, the first connecting terminal can still be connected with the main circuit bus, and the second connecting terminal can still be connected with the branch circuit bus. When the switch unit is inserted into the box body again, only the first connector and the second connector are required to be connected in a plugging mode, and therefore hot plugging is achieved, and the difficulty in maintenance of the plug box is reduced.

Compared with the situation that the plug box needs to be taken down from the main bus or the branch bus when the plug box is maintained in the prior art, the plug box provided by the embodiment of the application reduces the maintenance difficulty; in addition, after the repair, only the repaired or replaced device needs to be installed at the original position, and the connection with the main circuit bus and the branch circuit bus does not need to be disassembled.
Referring to fig. 11 and 12, in order to facilitate the switch unit 10 to be pulled out from the box body, the jack box provided in the embodiment of the present application further provides a power assisting structure 13. The force assist structure 13 may be used to help overcome the connection force between the first pin and the first socket and between the second pin and the second socket to facilitate the extraction of the switch unit 10. The number of assistant structures 13 is not particularly limited in the embodiment of the present application. If two booster structures 13 are used, the two booster structures 13 are symmetrically arranged.
The booster structure 13 includes a booster pin 131 provided in the case, and a booster wrench 132 provided in the switch unit and adapted to cooperate with the booster pin 131. The power assisting pin 131 is fixed in the case and is located at one side of the switch unit 10. The power wrench 132 is rotatably connected to the housing of the switch unit 10.
The power wrench 132 has a working end 1321, and the working end 1321 has a notch 1322 that mates with the power pin 131. When the working end 1321 rotates clockwise to a certain position, the notch 1322 is clamped on the power assisting pin 131, when the power assisting wrench 132 rotates again, the side wall of the notch 1322 presses against the power assisting pin 131, and the power assisting pin 131 serves as a supporting point to support the power assisting wrench 132 to rotate again, so that the switch unit is pulled out of the shell.
As an alternative, the power wrench 132 further includes a handle 1323. A handle 1323 is removably coupled to the working end 1321. When the power wrench 132 is needed, the handle 1323 can be fixed with the working end 1321; the handle 1323 may be removed when the power wrench 132 is not needed. Thereby reducing the space occupied by the booster structure 13.
As an alternative, as shown in fig. 12, the boosting structure 13 further includes an elastic member 133, and the elastic member 133 is used for driving the working end 1321 to avoid the boosting pin. The resilient member 133 serves to urge the working end 1321 into the retracted position. When the assist wrench 132 is not in use, the elastic member 133 pushes the working end 1321 to avoid the assist pin 131, and when the switch unit is inserted into the case, interference between the working end 1321 and the assist pin 131 can be avoided.
As an alternative, the elastic member 133 may be a different elastic member such as a torsion spring, a disc spring, a compression spring, and the like.
Referring to fig. 13 and 14, fig. 13 is an exploded schematic view illustrating a power module and a housing of a jack box according to an embodiment of the present disclosure. Fig. 14 shows an exploded view of the fan and housing. The power module 70 is provided at the left side plate of the body. In particular assembly, and with reference to fig. 9 and 13, the left side plate 213 includes a first portion 21132 and a second portion 21131. The first portion 21132 and the second portion 21131 are each independently removable. When the power module 70 is damaged, the first portion 21132 can be removed from the housing, allowing the power module 70 to be replaced without removing the entire jack box. When the fan 60 breaks down, the second portion 21131 can be directly detached, so that the fan 60 can be replaced, the whole plug box does not need to be detached, and the fan 60 is convenient to repair and replace.
Fig. 15 is a schematic view showing the structure of the first connection terminal 22 in fig. 15. The first connection terminal 22 is provided on the lower side plate 2112 of the body. The number of the first connection terminals 22 may be plural, and specifically, corresponds to the number of the main bus bars one by one. Illustratively, the first connection terminal 22 is a common duckbill-type connection terminal. The inner conductor of the first connection terminal 22 is copper alloy, and has good conductivity; the outer layer of the first connection terminal 22 is a stainless steel sheet. The copper alloy of the inner layer is protected by a stainless steel sheet. In addition, the force for clamping the main circuit bus bar by the copper alloy is provided by the stainless steel sheet.
The second connection terminal 27 is provided on the right side plate 2111 side of the case. A second connection end of the second copper bar extending out of the right side plate 2111 is connected to the second connection terminal 27. The second connection terminal 27 may be a different type of connection terminal, for example, the second connection terminal 27 may be a bus bar connector, or another type of connector.
As can be seen from the above description, the first connection terminal is located on a first surface of the case, the second connection terminal is located on a second surface of the case, and the first surface and the second surface are two adjacent surfaces. The first surface is the surface of the lower side plate exposed outside the box body; the second surface is the surface that the right side board exposes outside the box. When the mode is adopted for setting, the first connecting terminal and the second connecting terminal are located on different sides of the box body, and wiring of the main bus and the branch bus is facilitated. In addition, when the main circuit bus and the branch circuit bus are matched with the plug box, the use of other components, such as plugging and unplugging of a switch unit, plugging and unplugging of a monitoring module, dismounting and maintenance of a power supply module or a fan and the like, cannot be influenced.
As an alternative, the second connection terminal may be disposed on another surface, such as an upper side plate, a lower side plate, or a left side plate. When the outgoing line direction of the second connecting terminal is specifically set, the reasonable planning can be carried out according to the setting mode of other components in the jack box, and only the first connecting terminal needs to be avoided.
It can be seen from the above description that the jack box provided by the embodiment of the application can be directly connected with the main circuit bus and the branch circuit bus, so that the connection structure between the main circuit bus and the branch circuit bus is simplified, and convenience is brought to connection of buses of different types in a data center. In addition, the failure point is also reduced. The pluggable setting mode of the switch unit is adopted, when the switch unit is maintained, the whole plug box does not need to be taken down, and the maintenance difficulty is reduced.
The embodiment of the present application further provides a data center, where the data center includes an intensive bus, and the intensive bus includes two types of buses: main road bus and branch road bus.
The main road bus extends along the data center and is used as a main road for providing electric energy. The branch bus is used as a branch structure for supplying power to different devices. Referring to the application schematic diagram of the jack box shown in fig. 3, when the main bus bar is connected with the branch bus bar, the main bus bar is connected with the branch bus bar through the jack box, so that the main bus bar and the branch bus bar are electrically communicated.
The jack box adopted by the data center is any one of the jack boxes, the first connecting terminal of each jack box is connected with the main circuit bus, and the second connecting terminal is connected with the corresponding branch circuit bus. When the structure is adopted, the two connecting terminals are respectively connected with the main circuit bus and the branch circuit bus through the plug box, so that the connecting structure between the main circuit bus and the branch circuit bus is simplified, and convenience is brought to connection of buses of different types in the data center. In addition, the connection of the main circuit bus and the branch circuit bus can be realized by adopting the two connecting terminals, so that failure points are reduced. The pluggable setting mode of the switch unit is adopted, when the switch unit is maintained, the whole plug box does not need to be taken down, and the maintenance difficulty is reduced.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present application without departing from the spirit and scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations as well.
