Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar with a waterproof structure. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute a large amount of power to various components in a distributed system.

[0003] In response, existing technology patent publication number CN221633369U discloses a busbar trunking with a waterproof structure, including a busbar trunking body, which includes a conductive busbar and a first waterproof frame. A second busbar trunking is installed on the front side of the conductive busbar. Fixing plates are installed on the top and bottom of the conductive busbar. When the busbar trunking body and the second busbar trunking are connected, the second waterproof frame and the first waterproof frame are pressed together. The first waterproof frame moves backward under force, which drives a slider to move. The slider moves a moving block, which in turn deforms a spring. This deformation pushes the first waterproof frame forward. The first waterproof frame thus strengthens the tightness of the adhesion between the second and first sealing gaskets, achieving a stronger seal and preventing water from seeping into the interior from the connection point of the outer frame, thus preventing the conductive busbar from becoming damp and damaged.

[0004] However, in actual use, the two sets of sealing gaskets are installed by inserting the locking post and the locking slot. However, the locking post and the locking slot may become loose during subsequent use of the busbar trunking, and the two sets of sealing gaskets will also move away from each other. As a result, water can still enter between the sealing gaskets and flow to the surface of the busbar. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a busbar trunking with a waterproof structure to solve the problem mentioned in the background art, which involves the insertion of the locking post and the locking slot to fit two sets of sealing gaskets together. However, during subsequent use, the locking post and the locking slot of the busbar trunking may become loose, causing the two sets of sealing gaskets to drift apart. As a result, water may still enter between the sealing gaskets and flow onto the surface of the busbar.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a busbar trunking with a waterproof structure, including a first conductive busbar and a second conductive busbar, with fixing plates installed at the upper and lower ends of the first and second conductive busbars, heat sinks installed on the left and right surfaces of the first and second conductive busbars, a sealing component installed on the front outer surface of the first conductive busbar, and a docking component installed on the back outer surface of one end of the second conductive busbar.

[0007] The sealing assembly includes a groove formed inside the sealing assembly. A first sealing gasket is installed inside the groove. An installation frame is installed on the back of the sealing assembly. A rotating threaded rod is threaded inside the installation frame. The front end of the rotating threaded rod abuts against the back of the first sealing gasket. Both the mating assembly and the sealing assembly have sealing gaskets inside, and the two sets of sealing gaskets are mutually compatible.

[0008] Preferably, the docking component and the sealing component have the same structure and are installed symmetrically. The docking component includes a locking frame, and locking frames are installed on both the left and right sides of the docking component.

[0009] Preferably, inclined frames are installed on both the left and right sides of the fixed plate, a limit plate is installed on the upper surface of the inclined frame, and an inclined bottom plate is installed on the inner bottom wall of the inclined frame.

[0010] Preferably, a guide block is fixedly connected to the right side of the inclined frame, and a water outlet column is fixedly connected to the bottom end of the inclined frame. The interior of the water outlet column is provided with a cavity that matches the bottom end of the inclined frame, and the inner bottom wall of the inclined frame is higher at the front and lower at the back.

[0011] Preferably, positioning frames are installed on both the left and right sides of the sealing assembly, and an adapter block is installed inside the positioning frame, with a soft pad installed at the front end of the adapter block.

[0012] Preferably, the adapter block and the pad are internally fitted with threaded posts, and the threaded posts are threadedly installed with the positioning frame.

[0013] Preferably, the locking frame has an internal mounting groove and a threaded groove that are respectively adapted to the adapter block and the threaded post, and the threaded groove is recessed and installed inside the mounting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This busbar trunking with a waterproof structure allows the position of the first sealing gasket inside the groove to be adjusted by rotating the threaded rod, making the first and second sealing gaskets fit more tightly and preventing water from entering between the first and second conductive bars due to subsequent loosening. As a result, the sealing gasket fit of this configuration is tighter and will not loosen in the future. Furthermore, the tightness of the sealing gasket can be readjusted by repeatedly turning the threaded rod.

[0016] 2. In use, when the sealing component and the docking component are aligned and installed, the soft pad and the adapter block will enter the mounting groove inside the locking frame, and then the threaded post will also enter the threaded groove. Tightening the threaded post will cause it to move forward inside the threaded groove, thus moving the soft pad and the adapter block forward. After the soft pad is fully fitted inside the adapter groove, its elasticity allows the adapter block to compress it. When the front end of the positioning frame and the back end of the locking frame are fully fitted, the soft pad is under compression. Simultaneously, the threaded post is securely installed to the positioning frame via the threaded groove inside the locking frame. This design avoids the previous problem of unstable installation between the positioning frame and the locking frame, and solves the previous issue of loosening between them.

[0023] 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.

[0024] Please see Figures 1-5 One embodiment provided by this utility model:

[0025] The busbar trunking with a waterproof structure includes a first conductive busbar 1 and a second conductive busbar 4. Fixing plates 3 are installed at the upper and lower ends of the first conductive busbar 1 and the second conductive busbar 4. Heat sinks 2 are installed on the left and right surfaces of the first conductive busbar 1 and the second conductive busbar 4. A sealing component 5 is installed on the outer surface of the front end of the first conductive busbar 1. A docking component 10 is installed on the outer surface of one end of the back end of the second conductive busbar 4.

[0026] The sealing component 5 includes a groove 6, which is formed inside the sealing component 5. A first sealing gasket 7 is installed inside the groove 6. An installation frame 8 is installed on the back of the sealing component 5. A rotating threaded rod 9 is installed inside the installation frame 8. The front end of the rotating threaded rod 9 abuts against the back of the first sealing gasket 7. The docking component 10 has the same structure as the sealing component 5 and is installed symmetrically. The docking component 10 includes a locking frame 20, which is installed on both the left and right sides of the docking component 10. The upper and lower ends of the first conductive bus 1 and the heat sink 2 can be installed as a whole by setting two sets of fixing plates 3. Then the sealing component 5 is also installed on the outer surface of the fixing plates 3 and the first conductive bus 1. When the sealing component 5 and the docking component 10 are docked, the installation frame is turned. The internal rotating threaded rod 9 of 8 is rotated, and two sets of rotating threaded rods 9 are rotated simultaneously. At this time, the rotating threaded rod 9 will extend inside the groove 6, so that the front end of the rotating threaded rod 9 will abut against the back of the first sealing gasket 7. Then, rotating the threaded rod 9 can drive the first sealing gasket 7 to be tightly attached to the second sealing gasket inside the docking assembly 10. Thus, this setting can adjust the position of the first sealing gasket 7 inside the groove 6 by rotating the rotating threaded rod 9, so that the first sealing gasket 7 and the second sealing gasket are more tightly attached, preventing subsequent loosening that could lead to water ingress between the first conductive busbar 1 and the second conductive busbar 4. Thus, the sealing gasket of this setting has a tighter fit and will not loosen later. Moreover, the tightness of the sealing gasket can be readjusted by rotating the rotating threaded rod 9 multiple times.

[0027] An inclined frame 11 is installed on both the left and right sides of the fixed plate 3. A limit plate 13 is installed on the upper surface of the inclined frame 11. An inclined bottom plate 12 is installed on the inner bottom wall of the inclined frame 11. The interior of the water outlet column 15 is provided with a cavity that matches the bottom end of the inclined frame 11. The inner bottom wall of the inclined frame 11 is higher in the front and lower in the back. A guide block 14 is fixedly connected to the right side of the inclined frame 11. The bottom end of the inclined frame 11 is fixedly connected to the water outlet column 15. Because the inner bottom wall of the inclined frame 11 is higher in the front and lower in the back, the guided water will be guided into the interior of the water outlet column 15 through the inclined shape of the inclined bottom plate 12. The surface of the inclined bottom plate 12 is provided with holes that match the water outlet column 15. Thus, the water outlet column 15 can guide the rainwater away from the first conductive busbar 1 and the heat sink 2, resulting in a good overall waterproof effect.

[0028] Positioning frames 16 are installed on both the left and right sides of the sealing assembly 5. An adapter block 18 is installed inside the positioning frame 16, and a soft pad 19 is installed at the front end of the adapter block 18. Threaded posts 17 are inserted into the adapter block 18 and the soft pad 19, and are threadedly installed into the positioning frame 16. The locking frame 20 has mounting grooves and threaded grooves that respectively mate with the adapter block 18 and the threaded post 17. The threaded grooves are recessed into the mounting grooves. When the sealing assembly 5 and the mating assembly 10 are aligned and installed, the soft pad 19 and the adapter block 18 will enter the mounting grooves inside the locking frame 20, and then the threaded post 17 will also enter the threaded grooves. Then, the threaded post 17... When screwed, the threaded post 17 moves forward inside the threaded groove. The threaded post 17 then drives the soft pad 19 and the adapter block 18 to move forward. After the soft pad 19 is completely fitted inside the adapter groove, the adapter block 18 can squeeze the soft pad 19 because the soft pad 19 is elastic. When the front end of the positioning frame 16 and the back end of the locking frame 20 are completely fitted, the soft pad 19 is in a squeezed state. At the same time, the threaded post 17 is threadedly fastened to the positioning frame 16 through the threaded groove inside the locking frame 20. This setting can avoid the previous problem of unstable installation between the positioning frame 16 and the locking frame 20, and solve the previous situation where the positioning frame 16 and the locking frame 20 would be loose.

[0029] Working principle: In use, the first conductive busbar 1 and the heat sink 2 are installed as a whole by setting two sets of fixing plates 3. Then, the sealing component 5 is also installed on the outer surface of the fixing plate 3 and the first conductive busbar 1. When the sealing component 5 is connected with the docking component 10, the rotating threaded rod 9 inside the mounting frame 8 is turned at the same time. The rotating threaded rod 9 will extend inside the groove 6, so that the front end of the rotating threaded rod 9 will abut against the back of the first sealing gasket 7. Then, rotating the threaded rod 9 can drive the first sealing gasket 7 to be tightly attached to the second sealing gasket inside the docking component 10. Thus, this setting can adjust the position of the first sealing gasket 7 inside the groove 6 by rotating the rotating threaded rod 9, so that the first sealing gasket 7 and the second sealing gasket are more tightly attached.

[0030] When the sealing assembly 5 and the docking assembly 10 are aligned and installed, the soft pad 19 and the adapter block 18 will enter the mounting groove inside the locking frame 20, and then the threaded post 17 will also enter the threaded groove. Then the threaded post 17 is turned, and the threaded post 17 will move forward inside the threaded groove. Then the threaded post 17 will drive the soft pad 19 and the adapter block 18 to move forward. After the soft pad 19 is completely attached to the inside of the adapter groove, the adapter block 18 can squeeze the soft pad 19 because the soft pad 19 is elastic. When the front end of the positioning frame 16 and the back end of the locking frame 20 are completely attached, the soft pad 19 is in a compressed state. At the same time, the threaded post 17 is threadedly fastened to the positioning frame 16 through the threaded groove inside the locking frame 20. The above is the working principle of this utility model.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
