Description

Technical Field

[0001] The utility model relates to the technical field of combined electrical appliance branch busbars, in particular to a space turning device for different plane branch busbars of combined electrical appliances. Background Art

[0002] The space conversion of the branch busbar of the combined electrical appliance is relatively complex. The branch busbar mainly includes two parts: an external housing and an internal conductor. The conventional method for turning the branch busbar is to realize the spatial position conversion of the branch busbar through the combined use of multiple three-way conversion joints or four-way conversion joints. The existing three-way conversion joint has a T-shaped structure, and the four-way conversion joint has a cross-shaped structure. The ports in all directions are in a plane space, and only two branch busbars in the same plane can be turned and connected. For example, when the four-way conversion joint is placed horizontally, its four ports in the front, back, left, and right are all on the same horizontal plane, and only two branch busbars in the same plane can be converted in the front-back and left-right directions. However, when there is a height difference between two branch busbars that are not in the same plane, only by combining another four-way conversion joint or three-way conversion joint can the up-down direction conversion be realized to make up for the height difference. This combined turning method through multiple three-way conversion joints or four-way conversion joints has a high cost, a complex structure, a large occupied space, increases the installation difficulty, and is inconvenient for construction. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a four-way turning device that can convert the up-down direction, which is suitable for the direction conversion connection of two branch busbars not in the same plane, has great flexibility, is convenient to install, has strong reliability, saves the installation cost, and has high practical and economic value.

[0004] The utility model is realized through the following technical solutions. A space turning device for different plane branch busbars of combined electrical appliances includes a four-way housing. The four-way housing is provided with a first passage penetrating in the left-right direction and a second passage penetrating in the front-back direction. The first passage and the second passage are vertically distributed and are connected through a vertical third passage. A first contact seat assembly is arranged in the first passage, a second contact seat assembly is arranged in the second passage, and a conductor joint connecting the first contact seat assembly and the second contact seat assembly is arranged in the third passage.

[0005] In this solution, the first contact seat assembly in the first passage can be connected to the branch busbar in the left-right direction, and the first contact seat assembly in the second passage can be connected to the branch busbar in the front-back direction. The first passage and the second passage are vertically distributed to realize the turning connection of two branch busbars in different planes, and the conductor joint connects the first contact seat assembly and the second contact seat assembly to realize the up-down direction transfer of the first contact seat assembly and the second contact seat assembly. The structure is compact, the space occupation is reduced, the installation cost is lowered, and the use is more convenient.

[0006] As an optimization, the conductor joint is bolted to the first contact holder assembly and the second contact holder assembly. This optimization scheme facilitates disassembly and assembly.

[0007] As an optimization, a shielding ring is provided at the connection between the second contact holder assembly and the conductor joint. This optimization scheme shields the electric field at the tip of the conductor joint through the shielding ring.

[0008] As an optimization, the first contact holder assembly includes a T-shaped first main contact holder, and the conductor joint is connected to the vertical port of the first main contact holder to form a T-shaped conductive path. In this optimization scheme, the input current can turn and output to both horizontal sides through the T-shaped conductive path, improving the flexibility of connection with the branch bus.

[0009] As an optimization, intermediate contact holders are fixedly connected to both lateral ports of the first main contact holder, and plum blossom contact fingers are sleeved on the intermediate contact holders. This optimization scheme makes it convenient for the plum blossom contact fingers to connect with the terminal of the branch bus.

[0010] As an optimization, an open-type shielding cover is sleeved outside the plum blossom contact fingers. This optimization scheme shields the electric field at both ends of the first contact holder assembly through the open-type shielding cover.

[0011] As an optimization, the second contact holder assembly includes a T-shaped second main contact holder. One lateral port of the second main contact holder is fixedly connected to the support insulator of the second path port, and a closed-type shielding cover is installed at the other lateral port of the second main contact holder. The conductor joint is connected to the vertical port of the second main contact holder to form an L-shaped conductive path. This optimization scheme shields the electric field at the horizontal end of the second contact holder assembly through the closed-type shielding cover to form an L-shaped conductive path, facilitating the vertical transfer of the input current to the conductor joint.

[0012] As an optimization, countersunk flanges are fixedly connected to both ports of the first path, and external flanges are fixedly connected to both ports of the second path. This optimization scheme realizes the orthogonal connection between the four-way housing and the branch bus housing.

[0013] As an optimization, the four-way housing is an integrally formed structure. This optimization scheme is convenient for processing and improves the structural strength.

[0014] The beneficial effects of the present utility model are as follows: The branch buses in the left and right directions can be connected through the first contact holder assembly in the first path, the branch buses in the front and back directions can be connected through the first contact holder assembly in the second path, and the first contact holder assembly and the second contact holder assembly are connected through the conductor joint to realize the up-and-down transfer between the first contact holder assembly and the second contact holder assembly. The first path and the second path are distributed up and down to realize the turning connection of two branch buses in different planes. This device has a compact structure, reduces space occupation, lowers the installation cost, and is more convenient to use. Description of the Drawings
