Description

Technical Field

[0001] This article proposes the technical field of grounded connector top covers, specifically relating to a grounded bus connector top cover. Background Technology

[0002] Modern high-rise buildings and large workshops require enormous amounts of electrical energy, and to handle the hundreds or thousands of amperes of current demanded by these massive loads, safe and reliable transmission equipment is essential. Busbar systems are an ideal choice. Busbar systems are highly efficient power distribution devices, particularly suited to the economical and rational wiring needs of increasingly tall buildings and large-scale factories.

[0003] In the prior art, CN206076881U discloses a busbar trunking connection device, including a housing. The top of the housing is fixedly connected to a cover plate by a fastening nut. The interior of the housing has four matrix-arranged conductive busbar mounting holes. A partition is fixedly installed between the two upper conductive busbar mounting holes and the two lower conductive busbar mounting holes. A conductive copper base is fixedly installed on the inner wall of each conductive busbar mounting hole. A conductive spring is fixedly installed on the conductive copper base. A positioning pin is fixedly installed at the lower end of the conductive copper base. The internal structures of the upper and lower conductive busbar mounting holes are symmetrically arranged about the partition. Its advantages are: the invention has a simple structure and reasonable design, facilitating rapid connection of busbar trunking, improving work efficiency; and the use of conductive springs in conjunction with conductive copper bases can improve transmission stability and speed.

[0004] The connectors used in existing split busbar trunking systems are almost all split-type connectors with top and bottom opening. The advantage of such connectors is that they are easy to install, versatile, and can be quickly assembled and disassembled. However, precisely because of the split design, the connection between the connector and the busbar housing requires a special connecting housing for fixation. Therefore, the connector body and the connecting housing are both designed separately, which leads to a fatal flaw: the grounding wire of the busbar connector cannot be properly distributed. The body of the busbar connector cannot be independently grounded because it is directly connected to the busbar of the busbar trunking. Furthermore, because the connecting housing is connected to the busbar housing via a sliding groove, the grounding wire of the busbar connector can only be connected through a wire or a grounding lead-out bolt.

[0005] However, such a grounding wire not only disrupts the unity of the busbar trunking and connector connection, but also causes a grounding cable or bolt to extend independently from the outside of the busbar trunking, which also affects the unity of the busbar trunking. Summary of the Invention

[0006] This paper proposes a top cover plate for a grounded busbar connector. The busbar trunking is connected to the busbar connector via a mating connection. The top surface of the busbar connector is provided with a connector top cover plate, which is connected to both the busbar trunking and the busbar connector. The bottom surface of the connector top cover plate is provided with a cover plate base plate. Both ends of the bottom surface of the cover plate base plate are provided with grounding contact surfaces. Cover plate sliding edges are provided on both sides of the cover plate base plate, and cover plate guide grooves are provided above the cover plate sliding edges. The surface of the cover plate base plate is provided with fixing holes. The top of the busbar trunking and the connector are connected and fixed by using the connector top cover plate. The cover plate is precisely mated between the busbar trunking through a sliding groove method. The grounding contact surface is used to connect the ground wire of the connector to the busbar shell, so that there is no need to perform wiring or grounding bolts to ground the connector. This can ensure the integrity of the cover plate while maintaining the grounding function.

[0007] The cover plate base is rectangular, with cover plate sliding edges on both sides of the bottom. Cover plate guide grooves are mirror-image-outwards on both sides of the cover plate base. Three fixing holes are equidistantly spaced along the longitudinal centerline of the cover plate base. The cover plate sliding edges are rectangular strips located below the side plates of the cover plate base, with their bottoms flush with the bottom of the cover plate base. The length of the sliding edges is equal to the length of the cover plate base. The cover plate guide groove has a single-wing cross-section, with its arc facing outwards from the cover plate base. The inner shape of the guide groove is equal to the outer edge shape of the busbar trough. The cover plate can be slidably inserted into the outer casing of the busbar trough using the cover plate sliding edges and guide grooves. This not only improves the assembly speed of the cover plate but also ensures assembly accuracy. Furthermore, the slid grooves also serve as an auxiliary support, reinforcing the strength between the cover plate and the busbar trough.

[0008] The fixing hole is shaped like a waist hole. The longitudinal center line of the fixing hole is collinear with the longitudinal center line of the cover plate and the bottom plate. The fixing holes are equidistantly and collinearly set on the cover plate and the bottom plate. The cover plate is connected and fixed to the connector and the busbar through the fixing hole, thereby ensuring the stability of the connection between the connector and the busbar.

[0009] The connector top cover is made of metal, and the outer side of the top cover is coated with an insulating coating. Both ends of the bottom surface of the cover plate have grounding contact surfaces, which are metal layers with a film on their outer side. The metal cover allows the connector's ground wire to conduct. The insulating layer on the outer side of the cover ensures safety. The insulating layer on the grounding contact surface is ground away, allowing the metal surface to directly align with the busbar's outer shell. This ensures the ground wire conducts within the cover plate, guaranteeing safety. The film on the outer side of the grounding contact surface is removed before cover plate installation to ensure a clean surface free of dirt and residue, thus ensuring stable ground wire conduction.

[0010] Beneficial effects:

[0011] The busbar trough and the top of the connector are connected and fixed by using a top cover plate. The cover plate is precisely aligned between the busbar troughs using a sliding groove method. The grounding contact surface is used to connect the ground wire of the connector to the busbar shell, so that there is no need to perform wiring or grounding bolts to ground the connector. This ensures the integrity of the cover plate while maintaining the grounding function.

[0012] The cover plate can be slidably inserted into the outer casing of the busbar trunking by means of the cover plate sliding edge and cover plate guide groove. This not only improves the assembly speed of the cover plate, but also ensures the assembly accuracy. In addition, the sliding groove can also play another auxiliary support role to support the strength between the cover plate and the busbar trunking.

[0013] The cover plate is connected and fixed to the connector and busbar trunking through the fixing holes, thereby ensuring the stability of the connection between the connector and the busbar trunking.

[0014] The ground wire of the connector can only be made conductive through a metal cover plate. The insulating layer coated on the outside of the cover plate ensures safety. The insulating layer is ground off on the grounding contact surface, and the metal surface is directly connected to the outer shell of the busbar. This ensures that the ground wire is conductive inside the cover plate, ensuring safety. The film on the outside of the grounding contact surface is removed before the cover plate is installed to ensure that the grounding contact surface is clean and free of stains or other residues, thereby ensuring stable ground wire conduction.
