Description

[Technical Field]

[0001] This utility model relates to busbar trunking connection technology, and more particularly to an integrated cover structure for sealing connection at the joint of busbar trunking. [Background Technology]

[0002] Busbar trunking is a device used to distribute electricity, typically used for power transmission within buildings. Using busbar trunking makes the installation and maintenance of power distribution systems more convenient and efficient, significantly improving work efficiency and effectively enhancing the building's electrical safety. However, in existing busbar trunking systems, at the connection point between two busbar trunking sections, unreliable connections of the upper and lower end caps, improper installation, weak connections, or corrosion caused by environmental factors can lead to excessive contact resistance at the connector joint, resulting in temperature rise. In severe cases, this can cause the connector to burn out, leading to excessive residual current and overheating.

[0003] Therefore, the sealing of the busbar trunking connection is a critical issue. The cover must be able to effectively seal the busbar trunking to ensure that the internal electrical components are not affected by external factors such as dust and moisture. At the same time, the material used for the cover must have certain heat resistance, corrosion resistance, and wear resistance properties, and be suitable for harsh environments. [Utility Model Content]

[0004] This utility model provides an integrated cover structure for sealing the connection of busbar trunking joints. The overall structure is simple and easy to disassemble, effectively improving the sealing performance and reliability of the busbar trunking joints.

[0005] The technical solution adopted in this utility model is:

[0006] An integrated cover structure for sealing connection at the joint of busbar trunking, used for sealing connection at the joint of two busbar trunkings and above and below the connector, includes a first busbar trunking, a second busbar trunking adjacent to and connected to the first busbar trunking, and a busbar connector. The busbar connector is installed between the first busbar trunking and the second busbar trunking for locking connection of the connector busbar when the busbar trunking is connected.

[0007] The bus connector has two symmetrically arranged upper and lower end face covers that completely cover the upper and lower sides of the connector busbar. The two ends of the upper and lower end face covers are respectively attached to the upper and lower ends of the first busbar groove and the second busbar groove on both sides.

[0008] The upper end cap and the lower end cap are formed by integral stamping and folding of color steel plates.

[0009] Preferably, the upper end face cover and the lower end face cover are respectively bent with left and right folded edges that are fastened and sealed to the upper and lower edges of the first busbar groove and the second busbar groove. Corresponding to the inner side of the left and right folded edges, the four corners of the upper end face cover and the lower end face cover are respectively provided with spring washer bolts that are locked to the ends of the first busbar groove and the second busbar groove.

[0010] Preferably, the upper end cap and the lower end cap are respectively bent with front and rear folded edges that are fastened and sealed to the front and rear edges of the upper and lower sides of the bus connector.

[0011] Preferably, the inner surface of the upper end cover and the lower end cover is further recessed and stamped with hexagonal grooves along the circumference, which are nested and cooperate with the upper and lower end faces of the bus connector to prevent external dust and moisture from sealing and protecting the internal electrical components. The hexagonal grooves are filled with high-temperature sealing silicone for sealing the connection at the joint.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the bus connector has upper and lower end face covers respectively attached to the upper and lower ends of the first and second bus troughs. The upper and lower end face covers are symmetrically arranged and completely cover the upper and lower sides of the entire connector busbar. The upper and lower end face covers are nested with the upper and lower ends of the bus connector through hexagonal grooves and sealed at the joint by filling with high-temperature sealing silicone, effectively preventing external dust and moisture from entering. At the same time, the four feet of the upper and lower end face covers are locked to the end faces of the first and second bus troughs by spring washers and bolts. The overall structure is simple and effectively improves the sealing performance and reliability of the bus trough joint. [Attached Image Description]
