Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a closed connector for busbars. Background Technology

[0002] Busbar joints are a crucial component in busbar systems, used to connect different busbar sections. Their function is to connect different busbar sections, ensuring stable power transmission and preventing external environmental influences on the joint. Existing sealed joints often consist of a cover plate with a sealing ring installed at the end of the busbar. However, these joints have relatively large gaps at the connection point, and over time, wear, aging, or deformation can lead to poor sealing. This allows external dust, moisture, or oil to enter the joint, affecting system stability. Utility Model Content

[0003] The purpose of this utility model is to provide a closed connector for busbar trunking to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a closed joint for a busbar trunking, comprising:

[0005] The bottom cover has fasteners fixed to its top.

[0006] Side plates, two side plates are provided and symmetrically placed on the top of the bottom cover. Rubber blocks that cooperate with busbar grooves are fixed to both ends of the side plates. Connecting seats are fixed to the bottom of the outer side of each side plate. A rectangular hole for cooperating with fasteners is opened in the middle of the connecting seat. The two side plates, the bottom cover and the busbar grooves at the ends of the side plates form a glue potting cavity.

[0007] An insulating sheet is placed between the two side plates, a conductive plate is installed on the side of the insulating sheet, and a threaded rod is installed in the middle of the insulating sheet.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a closed connector for a busbar trunking, comprising: a bottom cover 1, with fasteners fixedly attached to the top of the bottom cover 1; two side plates 4 are provided and symmetrically placed on the top of the bottom cover 1, with rubber blocks 6 that cooperate with the busbar trunking fixedly attached to both ends of the side plates 4, and connecting seats 7 fixedly attached to the bottom of the outer side of each side plate 4, with a rectangular hole in the middle of the connecting seat 7 for use with the fasteners, the two side plates 4, the bottom cover 1, and the busbar trunking at the ends of the side plates 4 forming a glue-filling cavity 12; an insulating sheet 14 is placed between the two side plates 4, with a copper plate installed on the side of the insulating sheet 14, and a threaded rod 10 installed in the middle of the insulating sheet 14, the diameter of the hole in the middle of the copper plate being larger than the diameter of the hole in the middle of the insulating sheet 14.

[0023] It should be noted that in this embodiment, the connecting piece at the end of the busbar trough is inserted into the gap between the insulating sheets 14, and then the connector at the top of the bottom cover 1 is inserted into the hole in the middle of the connecting seat 7. The end of the busbar trough is pressed and fitted with the rubber block 6 at the end of the side plate 4. The side plate 4 is compressed and contracted by tightening the threaded rod 10, thereby pressing the insulating sheet 14 through the side plate 4, thereby pressing and connecting the copper plate to the connecting piece at the end of the busbar trough. Then, the connecting seat 7 is fixed to the top of the bottom cover 1 by the connector. At this time, the two side plates 4, the busbar troughs at both ends, and the bottom cover 1 form a top-opening glue-filling cavity 12. By pouring sealant into the glue-filling cavity 12, after the glue solidifies, the glue will wrap the entire connection part, thereby achieving a seal.

[0024] In one embodiment, a top cover 3 is also included, which is fixed to the top of the side plate 4. The top cover 3 is connected to the busbar grooves at both ends, and a sealing gasket 13 is bonded to the bottom of the top cover 3 and the top of the bottom cover 1.

[0025] It should be noted that in this embodiment, the top of the busbar trough and the top of the side plate 4 are at the same height. The bottom of the top cover 3 is fixedly connected to the gull sealing gasket 13. The top cover 3 and the busbar trough are connected by screws, so that the top cover 3 covers the top of the side plate 4, thereby resealing the inside of the side plate 4.

[0026] In one embodiment, the fastener includes a bolt 8 fixed to the top of the bottom cover 1, the end of the bolt 8 passing through the center of a rectangular hole and threaded with a tightening nut 9.

[0027] It should be noted that, in this embodiment, when the insulating sheet 14 is fitted with the connecting piece at the end of the busbar trough, the bolt 8 is inserted into the connecting seat 7. When the spacing of the side plate 4 is adjusted by the metal block 11, the connecting seat 7 slides on the outside of the bolt 8. When the side plate 4 and the insulating sheet 14 clamp the connecting piece, the tightening nut 9 is tightened on the outside of the bolt 8, so that the tightening nut 9 is pressed against the top of the connecting seat 7, thereby fixing the side plate 4 to the bottom cover 1. The connection between the side plate 4 and the bottom cover 1 is then sealed by the sealing gasket 13.

[0028] In one embodiment, a connecting plate 2 is fixedly connected to both sides of the bottom cover 1, and the connecting plate 2 has a through hole that matches the side of the busbar trough.

[0029] It should be noted that, in this embodiment, when the busbar trough is fitted with the end of the side plate 4, the end of the busbar trough is squeezed against the rubber block 6 to seal the connection between the end of the side plate 4 and the end of the busbar trough. After the connection is completed, the side plate 4 is connected to the side of the busbar trough by screws through the through hole in the middle of the connecting plate 2, thereby securing the connection between the side plate 4 and the bottom cover 1 and preventing glue leakage during glue injection.

[0030] In one embodiment, the threaded rod 10 passes through the middle of the two side plates 4, and a metal block 11 is threadedly connected to one side of the threaded rod 10. The metal block 11 is slidably installed on the outside of one of the side plates 4. An injection groove 5 is provided on the side of the side plate 4, and a groove 15 is provided on the top of the insulating sheet 14.

[0031] It should be noted that in this embodiment, a limiting plate is sleeved on the end of the threaded rod 10 away from the metal block 11. A rubber pad is bonded to the side of the limiting plate and the metal block 11 to seal the connection between the side plate 4 and the threaded rod 10, reducing the probability of glue leakage. By rotating the threaded rod 10, the threaded rod 10 and the metal block 11 are threadedly connected. Under the action of the thread, the two side plates 4 are brought together, thereby achieving the clamping of the insulating sheet 14 by the side plate 4. When the clamping and assembly are completed, glue is injected into the top of the insulating sheet 14. The glue quickly enters the bottom of the insulating sheet 14 through the glue injection groove 5 on the side of the side plate 4, filling it from bottom to top. This can reduce the air inside after the glue is formed. After the glue is filled, the top groove 15 of the insulating sheet 14 is filled, thereby increasing the contact surface between the insulating sheet 14 and the glue.
