Abstract

The invention discloses a power distribution box. The power distribution box comprises a bottom plate located at the bottom, wherein the bottom plate is provided with a front panel, a rear side plate,a left side plate and a right side plate; a cover plate I and a cover plate II are disposed on the top to form a closed box shape; the plates are detachably connected; and each plate is provided witha plurality of mounting holes. The internal components can be repaired by opening the cover plate II, thereby greatly improving the safety and maintainability of the product and facilitating the external-field maintenance of the power distribution box. According to the power distribution box disclosed by the invention, the ground power supply conversion can be provided while the on-vehicle electrical conversion is implemented, a large amount of internal components in various types are provided, the product volume is small and the space utilization rate is high.

Description

technical field [0001] The invention belongs to the field of aircraft power supply control, and in particular relates to a power distribution box. Background technique [0002] The new power distribution box is a structural part of the aviation control device, which is used for the high-power power supply control device on the aircraft. It has a small size and a compact internal layout. In the past, the structural characteristics of the power distribution box were large volume, heavy weight, low space utilization, poor interchangeability, and long maintenance time. This type of structure added great difficulty to the development of a new ground effect aircraft power distribution device. In order to meet the requirements of small size, light weight and diversified functions of the new power distribution box, the development of the new power distribution box is imperative. Contents of the invention [0003] purpose of invention [0004] A power distribution box is provided...
