Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to an assembling wiring device for a power distribution cabinet. Background Art

[0002] A distribution cabinet is a key component used in an electric power distribution system. It is used to centrally manage, protect, and distribute electrical energy. The wiring device of a distribution cabinet refers to a device used to connect, distribute power, and protect circuits in an electrical system. The wiring device of a distribution box refers to a device used to connect, distribute power, and protect circuits in an electrical system. Prior art publication number CN207265249U proposes a wiring device for a distribution box, comprising a base, a cover, and a terminal block. The base and the cover are both insulated. The base comprises a bottom plate and side plates that are perpendicular to each other. The side plates extend from a side edge in the length direction of the bottom plate in a direction away from the bottom plate. The cover comprises a top plate and a cover plate that are perpendicular to each other. The cover plate extends from a side edge in the length direction of the top plate in a direction away from the top plate. The top plate is connected to the side plate and the cover plate is connected to the bottom plate. The terminal block is provided on the bottom plate and is located between the base and the cover. The cover plate is provided with a threading hole, and the top plate is provided with an adjustment hole. The patent provides a wiring device for a distribution box. The base and cover are combined to form a housing cavity. The terminal block is located within the housing cavity.
