Problems solved by technology

[0004] The disadvantage of the above-mentioned prior art is that since the length of the PDU is generally long and complex, and the conductive shrapnel in each power-taking unit is electrically connected to the copper wire through a wire, resulting in welding on each copper wire. There are many points, and each solder point on the copper wire is easy to heat up. As the temperature rises, the stability of the solder joints decreases, and the heat generation is large, which will make it difficult to increase the overall load of the PDU.
[0005] However, in the power distribution industry, it is necessary to ensure that one of the two contacting parts is elastic and the other is rigid when taking power, so as to ensure stable contact between the two parts for taking power. At present, the rigid parts in the industry are all plugs, elastic The parts are set in the power-taking holes, and most of the elastic parts are conductive shrapnel, and the setting of the conductive shrapnel needs to be welded with copper wires, so it has become a difficult point in the industry and has always been difficult to solve

Abstract

The present invention relates to the technical field of power distribution devices, in particular to a PDU power-taking device, including a power transmission conductor and an electrical connection device, the power connection device includes at least two power-taking structures, and the power transmission conductor includes at least two, The power transmission conductor is made of hard conductive material and is rigid, the power taking structure is a deformable structure, and the power taking structure and the power transmission conductor are pressed contact type power taking, and the power taking structure squeezes the power transmission conductor. The power transmission conductor is a rigid conductive material. At this time, the power transmission conductor can be made into an overall structure without solder joints. The power-taking structure can directly contact the power transmission conductor through its own elasticity or elastic movable structure to realize contact power-taking. At this time The absence of solder joints between the power transmission conductor and the power-taking structure reduces the number of intermediate connection points of the power distribution device and improves reliability. The PDU power-taking device has better heat dissipation performance and lower temperature rise, which is convenient for increasing the load of the PDU power-taking device and has higher stability.

Description

technical field [0001] The invention relates to the technical field of power distribution devices, in particular to a PDU power-taking device. Background technique [0002] PDU (Power Distribution) is the abbreviation of power distribution unit, which is often used in power distribution sockets for cabinets. PDU is a product designed to provide power distribution for cabinet-mounted electrical equipment. [0003] The existing PDU architecture includes a housing, copper wires, and conductive shrapnel. Both the copper wire and the conductive shrapnel are arranged in the housing, and there are several power-taking holes on the housing. Root, multiple power-taking holes form a power-taking unit, and the conductive shrapnel of the power-taking holes in each power-taking unit is electrically connected with the corresponding copper wire through a wire. [0004] The disadvantage of the above-mentioned prior art is that since the length of the PDU is generally long and complex, and ...
