Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 6, a power distribution unit in a hot plug cabinet comprises a U-shaped plastic shell 4, an insulating support 2 is arranged in the shell 4, five sliding grooves are arranged on the insulating support 2 and are parallel, copper bars 1 are assembled in the sliding grooves, the five copper bars 1 are sequentially arranged from top to bottom according to the line sequence of phase a, phase B, phase PE, phase C and phase N, the power distribution unit further comprises a plurality of power taking modules 6, the power taking modules 6 comprise an upper cover 61 which is connected to the shell 4 in a buckling manner, the upper cover 61 is provided with a power taking unit 62 and a plurality of power taking claws 64, the power taking claws 64 are slidably inserted into the copper bars 1 to be in contact with the copper bars 1, the power taking claws 64 can slide in the copper bars 1, one end of the shell 4 is buckled and connected with a wiring cover 7, a wiring box 8 is arranged on the wiring cover 7, and terminal bars arranged in the wiring box 8 are connected with one end of each copper bar 1 through five wires in a tin soldering manner, and the terminal bars are connected to a power distribution system of the upper stage.

When a new function is to be added, the old power taking module 6 is only required to be taken off from the shell 4 as a whole, and a new power taking module 6 with a function intended by a user is assembled on the shell 4, so that the function can be added, for example, a plug (power taking unit 62) in fig. 1 is changed into a blank state, a current voltmeter, an indicator lamp and the like. When the user needs to modify the position of the power take-off module 6, the power take-off module 6 may be translated directly.

Insulation plugs 3 are fixedly connected in the two ends of the sliding groove. The insulating plug 3 plugs the two ends of the insulating support 2 in an ultrasonic welding mode, and prevents the copper bars 1 from falling out from the sliding place.

The shell 4 is connected with the insulating support 2 through a clamping groove, and end covers 5 are inserted into two ends of the shell 4. The insulating holder 2 is fixed by the end cap 5, and the insulating holder 2 is prevented from slipping out of the housing 4.

The interval between two adjacent sliding grooves in the plurality of sliding grooves is unequal to the interval between two adjacent sliding grooves. Plays a foolproof role and avoids the reverse insertion of the power taking module 6.

The copper bar 1 is a structure with an M-shaped section formed by bending an elastic copper strip, such as beryllium bronze. The copper bar 1 with the shape meets the area requirement of the current-carrying copper bar 1 and the clamping force requirement of the electric connection of the power taking claw 64, and reduces the space occupation.

The end of the power taking claw 64 is provided with a chamfer. The chamfering facilitates the insertion of the electricity taking claw 64 into the copper bar 1, and meanwhile, the electricity taking claw 64 is clamped by the copper bar 1 in two directions, so that the requirements of the conductive sectional area of the electricity taking claw 64 and the positioning requirements during butt joint can be met.

Auxiliary screws 63 are connected to both ends of the upper cover 61. When the power take-off module is to be taken out, the auxiliary screws 63 on the two sides of the power take-off module 6 are grasped by hands and pulled outwards by force, and the power take-off module 6 is pulled out from the inclined buckle of the base of the shell 4.

The embodiments described in the present specification are merely examples of implementation forms of the inventive concept, and the scope of protection of the present utility model should not be construed as being limited to the specific forms set forth in the embodiments, and the scope of protection of the present utility model and equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
