Its installation form is flexible, and its functions can be modular and diversified, and it can provide a variety of output jacks and their combined output jacks. It can provide safe, professional and convenient power distribution services for servers or other electrical equipment in the cabinet, and is widely used in the terminal power distribution industry. The defect of the existing power distribution unit in the hot-pluggable cabinet is that once the production is completed, all technical parameters of the product are fixed and cannot be modified. To replace, add or reduce functions or quantities, it is necessary to replace the finished product, and the scope of application is small. Content of the Utility Model
[0003] The purpose of the utility model is to provide a power distribution unit in a hot-pluggable cabinet, which is used to solve the problems of fixed technical parameters and small scope of application of the existing power distribution unit in the hot-pluggable cabinet.

[0005] A power distribution unit in a hot-pluggable cabinet includes a housing, an insulating bracket inside the housing, a plurality of chutes are provided on the insulating bracket, copper bars are assembled in the chutes, and further includes a plurality of power-taking modules. The power-taking module includes an upper cover snap-connected to the housing, a power-taking unit and a plurality of power-taking claws are installed on the upper cover, and the power-taking claws are connected to the copper bars.
[0006] Insulating plugs are fixedly connected inside both ends of the chute.
[0007] The housing and the insulating bracket are connected through a card slot, and end caps are inserted at both ends of the housing.
[0008] The distance between two adjacent chutes in one of the plurality of chutes is not equal to the distance between two adjacent chutes in other chutes.
[0009] The copper bar is bent into a structure with an "M"-shaped cross section by an elastic copper strip.
[0010] The end of the power-taking claw is provided with a chamfer.
[0011] The beneficial effects of the utility model are as follows:
[0012] 1. After production, and even after being installed in the on-site cabinet, the utility model allows the technical parameters to be continuously modified, including the maximum load current of the power-taking module, the number of output jacks, the type of output jacks, or the addition or deletion of the functions of the power-taking module.
[0013] 2. The utility model can take power from the copper bars at any position of the whole product, enabling the power-taking module to be installed at any position or the order positions of several power-taking modules to be arbitrarily swapped.
[0014] 3. The power-taking module in the utility model can directly replace modules with different functions to quickly respond to customer needs. For example: the original power-taking module is one with a circuit breaker, which can be directly replaced with a current-voltage meter according to customer requirements, or the indicator light can be changed to a push-button switch with an indicator light.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.
[0024] As Figures 1 to 6As shown in the figure, a hot-swap power distribution unit inside a cabinet includes a U-shaped plastic housing 4. Inside the housing 4, there is an insulating bracket 2. The insulating bracket 2 is provided with five sliding grooves, and the five sliding grooves are arranged in parallel. Inside each sliding groove, a copper bar 1 is assembled. The five copper bars 1 are arranged in sequence from top to bottom according to the line sequence of phase A, phase B, PE, phase C, and phase N. It also includes multiple power-taking modules 6. The power-taking module 6 includes an upper cover 61 snap-connected to the housing 4. An electricity-taking unit 62 and multiple power-taking claws 64 are installed on the upper cover 61. The power-taking claws 64 are slidably inserted into the copper bar 1 and are in contact with the copper bar 1, and the power-taking claws 64 can slide within the copper bar 1. At one end of the housing 4, a wiring cover 7 is snap-connected. A wiring box 8 is installed on the wiring cover 7. The terminal block arranged inside the wiring box 8 is soldered to one end of each copper bar 1 through five wires, and the terminal block is connected to the upper-level power transmission and distribution system.
[0025] When new functions need to be added, only the old power-taking module 6 needs to be removed from the housing 4 as a whole, and a new power-taking module 6 with the functions desired by the user is installed and assembled onto the housing 4, then the functions can be increased. For example: changing the plug (power-taking unit 62) in Figure 1 to an air switch, an ammeter and voltmeter, an indicator light, etc. When the user needs to change the position of the power-taking module 6, the power-taking module 6 can be directly translated.
[0026] Insulating plugs 3 are fixedly connected inside both ends of the sliding groove. The insulating plugs 3 use ultrasonic welding to block both ends of the insulating bracket 2 to prevent the copper bar 1 from falling out from the place where it slides in.
[0027] The housing 4 and the insulating bracket 2 are connected through a card slot, and end caps 5 are inserted at both ends of the housing 4. The end caps 5 are used to fix the insulating bracket 2 to prevent the insulating bracket 2 from sliding out of the housing 4.
[0028] The distance between two adjacent sliding grooves in one of the multiple sliding grooves is not equal to the distance between two adjacent sliding grooves in other cases. This has an anti-fooling effect and can prevent the power-taking module 6 from being inserted in the wrong direction.
[0029] The copper bar 1 is bent from an elastic copper strip into a structure with a cross-section of "M" shape. The elastic copper strip is, for example, beryllium bronze. The copper bar 1 of this shape takes into account both the area requirement of the current-carrying copper bar 1 and the clamping force requirement for electrical connection with the power-taking claws 64, and reduces the space occupation.
[0030] The end of the power-taking claw 64 is provided with a chamfer. The chamfer facilitates the insertion of the power-taking claw 64 into the copper bar 1. At the same time, the power-taking claw 64 is clamped by the copper bar 1 in two directions, which can simultaneously meet the requirements of the conductive cross-sectional area of the power-taking claw 64 and the positioning requirements during docking.
[0031] Auxiliary screws 63 are connected to both ends of the upper cover 61. When it is to be taken out, hold the auxiliary screws 63 on both sides of the power-taking module 6 by hand and pull outwards forcefully, and the power-taking module 6 will be pulled out from the inclined surface buckle of the base of the housing 4.
[0032] The content described in the embodiments of this specification is only a list of the implementation forms of the utility model concept. The protection scope of the present utility model should not be regarded as limited to the specific forms stated in the embodiments, and the protection scope of the present utility model also extends to equivalent technical means that those skilled in the art can think of based on the utility model concept.
