Description

Technical Field

[0001] The present invention relates to the field of electrical connection devices, in particular to a rapid electrical connection device for a rotary drawer unit. Background Art

[0002] A drawer-type power distribution device is a low-voltage power distribution equipment with a modular design, mainly used for power distribution, control, and protection. Its core feature is the flexible operation and safe maintenance through a pull-out independent drawer unit. The working principle of this device is as follows: Current is introduced through an incoming line cabinet, distributed to each drawer unit through a bus duct, and then controlled by components such as circuit breakers and contactors to output to load devices. In the existing drawer-type power distribution devices, several aviation plug components are fixed on the drawer. When the drawer is pushed into the electrical cabinet, the electrical connection between the aviation plug components and external components is completed. However, in the distribution device with this structure, the aviation plug components can only move linearly in one direction. When the positions of the components are not in the same direction, the connection with components in different directions cannot be completed. There are also some distribution devices in which the aviation plug components can move in different directions, but their internal structures are complex, the volume is large, and the cost is high.

The component mounting plate 6 is fixed on the bottom plate 1. The first push mechanism 2 for pushing the first aviation plug component 3 and the second aviation plug component 4 is mounted on the bottom plate 1. The first aviation plug component 3, the second aviation plug component 4, and the auxiliary aviation plug component 5 are all slidably connected to the bottom plate 1. The movable part of the first push mechanism 2 of the aviation plug component is connected to the first aviation plug component 3 and the second aviation plug component 4. The second push mechanism 7 of the aviation plug component for pushing the auxiliary aviation plug component 5 is mounted on the bottom plate 1, and the second push mechanism 7 of the aviation plug component is connected to the auxiliary aviation plug component 5.

[0019] As shown in the appendedFigure 2 As shown in Figure 2 , the first push mechanism 2 of the aviation plug assembly includes an upper cover 21, a lower cover 22, a longitudinal connecting plate 23, a transverse connecting plate 24, a cam assembly 25, and a handle 26. The upper cover 21 and the lower cover 22 are both fixed on the bottom plate 1. The cam assembly 25 is fixedly connected to the handle 26. The cam assembly 25 is rotatably connected inside the upper cover 21. The cam assembly 25, the longitudinal connecting plate 23, and the transverse connecting plate 24 are arranged successively from top to bottom between the upper cover 21 and the handle 26. A longitudinal arc groove 27 is provided on the longitudinal connecting plate 23, and a transverse arc groove 28 is provided on the transverse connecting plate 24.

[0020] The cam assembly 25 includes a runner 251, a shaft rod 252, and an operation hole 253. The shaft rod 252 is eccentrically arranged on the runner 251. An operation hole 253 is provided on the side of the runner 251. The shaft rod 252 passes through the longitudinal arc groove 27 and the transverse arc groove 28. The user can insert a lever into the operation hole 253 to rotate the runner 251.

[0021] After holding the handle on the runner 251 and rotating the runner 251, the shaft rod 252 on the runner 251 will move along the longitudinal arc groove 27 on the longitudinal connecting plate 23 and the transverse arc groove 28 on the transverse connecting plate 24. When the shaft rod 252 moves along the longitudinal arc groove 27, it will push the longitudinal connecting plate 23 to drive the first aviation plug assembly 3 to move longitudinally forward and insert into the component. When the shaft rod 252 moves along the transverse arc groove 28, it will push the transverse connecting plate 24 to drive the second aviation plug assembly 4 to move transversely forward and insert into the component. In this way, the first aviation plug assembly 3 and the second aviation plug assembly 4 are inserted into components with different orientations in sequence. Relying on the movement of the shaft rod 252, the first aviation plug assembly 3 and the second aviation plug assembly 4 can also be driven to move in the reverse direction and disengage from the component.

The limit pin 9 passes through the kidney-shaped hole 10.

[0025] When the longitudinal slide plate 8 moves, the limit pin 9 also moves relatively along the kidney-shaped hole 10, thereby restricting the moving distance of the longitudinal slide plate 8 and making the movement of the first aviation plug component 3 more stable and accurate.

[0026] The second aviation plug component 4 includes a plug 41, a plug fixing member 42, and a transverse slide plate 43.

[0030] When the push plate 71 rotates around the rotating pin 73, the push plate 71 will push the longitudinal connecting plate 72 to drive the auxiliary aviation plug component 5 to move forward longitudinally, so as to insert into the component. When the push plate 71 rotates in the reverse direction, the auxiliary aviation plug component 5 will be pulled back and separated from the component.
