Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a multi-layer bus duct. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute high power to various components of the distributed system. Plug-in bus duct has emerged as a new type of distribution conductor. Compared with traditional cables, it is more convenient, safe and reliable to use due to the emergence of different new technologies and processes.

[0003] After searching, the Chinese patent authorization number CN201120214533.1 discloses a multi-layer dense insulation bus duct device, in which insulating spacers are provided between multiple groups of serial copper bus conductors, and multiple groups of serial copper bus conductors are clamped between two aluminum alloy side plates, which are connected to the bus duct body cover. Due to the multiple groups of serial copper bus conductors, the multi-layer dense insulation bus duct has more sockets; multiple groups of copper bus conductors are tightly clamped between the two aluminum alloy side plates, which facilitates the copper bus conductors to dissipate heat outward. Since the aluminum alloy side plates are connected to the bus duct body cover, heat can be easily transferred from the aluminum alloy side plates to the bus duct body cover, thereby expanding the area for the copper bus conductors to dissipate heat outward.

[0004] The multi-layer densely insulated bus duct device in the above patent has the following shortcomings: First, the installation of the above bus duct is directly fixed by bolts, but due to the interlaced installation of the internal heat-conducting components and the busbar, the fixing components are easy to loosen when subjected to vibration, and the heat-conducting structure and the busbar are also easy to wear each other, which reduces the overall durability. At the same time, the single heat conduction makes it difficult to dissipate heat quickly, and the heat dissipation effect is also low. Secondly, the bolt fixing method is not convenient for quick removal, which reduces the use effect.

[0005] To this end, we propose a multi-layer bus duct to solve the above problems. Utility Model Content

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0031] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0032] A multi-layer bus duct provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Combine Figure 1-Figure 4 As shown, the utility model provides a multi-layer bus duct,

[0035] Specifically, it includes a busbar main body shell 1 and a busbar 2. The outer ends of both sides of the busbar main body shell 1 are sleeved with a fixed sleeve shell 3. A rotating rod 9 is rotatably installed on the upper inner side of the fixed sleeve shell 3. The middle part of the rotating rod 9 is sleeved with a transmission gear 11. The rear end of the transmission gear 11 is engaged with a lifting gear rod 12 for transmission connection. The outer side of the busbar main body shell 1 is close to the inner side of the fixed sleeve shell 3. A embedding groove 17 is opened. The bottom end of the lifting gear rod 12 is located inside the embedding groove 17 and is connected to a suction cup 15. The busbar 2 is located on the inner side of the busbar main body shell 1 and is sleeved with an embedded protective plate 4. The embedded protective plate 4 is mainly convenient for embedding and fixing the busbar 2 as a whole. The outer side of the busbar 2 is located inside the embedded protective plate 4 and is provided with a sealing protective pad 6. The sealing protective pad 6 is convenient for the embedded card connection of multiple sets of heat-conducting strips 5, and also provides sealing protection for the busbar. The outer side of the sealing protective pad 6 is evenly embedded with multiple sets of heat-conducting strips 5. The tops of the multiple sets of heat-conducting strips 5 are connected with metal heat-conducting springs 7. The tops of the metal heat-conducting springs 7 are close to the inner side surfaces of the embedded protective plate 4. A heat-conducting adsorption member 8 is provided between the tops. The heat-conducting adsorption members 8 are respectively composed of an adsorption hollow pad 801, a convex heat-conducting sheet 802 and an adsorption hole 803. The outer side of the lifting gear rod 12 is symmetrically connected with a connecting rod. The slider 14 and the coordinated operation of the connecting slider 14 and the slide 13 make the lifting and lowering movement of the lifting gear rod 12 have a certain limiting and stabilizing effect. The connecting slider 14 is provided with a slide 13 on the side close to the fixed sleeve shell 3. The connecting slider 14 is interactively embedded in the inner side of the slide 13. One end of the convex heat conductive plate 802 extends through the interior of the adsorption hollow pad 801 embedded in the adsorption hollow pad 801. The other end of the convex heat conductive plate 802 is connected to one end of the metal heat conductive spring 7. One side of the heat conductive strip 5 is close to the outer side of the busbar 2. The upper and lower ends of the suction cup 15 and the side of the embedded protective plate 4 are provided with through holes 16. The through holes 16 are both square. It is convenient for adsorption with the adsorption hole 803, and it is also convenient for the discharge of hot air. The through hole 16 and the adsorption hole 803 are correspondingly abutted and connected. The through hole 16 and the adsorption hole 803 are connected to the sealing protection pad 6. The use of the above components makes the suction cup 15 and the thermal adsorption component 8 adsorbed stably to each other. At the same time, the metal thermal conductive spring 7 absorbs the heat guided by the thermal conductive strip 5 through the busbar 2, and due to the effect of thermal expansion and contraction, the suction cup 15 is more strongly adsorbed and fixed. At the same time, the elastic vibration of the metal thermal conductive spring 7 also makes the suction cup 15 and the adsorption hollow pad 801 dissipate heat, which not only improves the fixing stability, reduces wear and improves durability, but also improves the heat dissipation effect.

[0036] Example 2:

[0037] Combine Figure 3 and Figure 4 As shown, based on the first embodiment,

[0038] Specifically, one end of the rotating rod 9 passes through one side of the fixed sleeve shell 3 and is connected to a transmission handle 10, which is embedded in the side of the fixed sleeve shell 3. The above-mentioned components include the operation and use of each component in the first embodiment, especially the adjustment of the transmission handle 10 so that each component operates to embed the suction cup 15 into the embedding groove 17 or move it out of the embedding groove 17 for fixing or separation. This not only improves the convenience of disassembly and assembly, but also improves the overall use effect.

[0039] Combine Figure 1 and Figure 2 As shown, in the above embodiment,

[0040] Specifically, one end of the busbar 2 is connected to the inner side of the two ends of the busbar main shell 1 through an embedded protective plate 4. The front end of the transmission gear 11 is located on the outside of the fixed sleeve shell 3 and a heat dissipation grille 18 is provided. The heat dissipation grille 18 is mainly used to facilitate the discharge of hot air.

[0041] The working principle and use process of the present invention are as follows: First, when in use, the transmission handle 10 is adjusted to drive the rotating rod 9 so that the transmission gear 11 rotates, and the lifting gear rod 12 engaged with the transmission is driven to move up and down, and the suction cup 15 at the bottom is embedded in the embedding groove 17 or removed from the embedding groove 17, and the fixed sleeve shell 3 can be quickly separated from the busbar main body shell 1 to complete the fixation and disassembly, which is convenient for subsequent use and improves the use effect. Secondly, when in use, through the meshing transmission of the above-mentioned transmission gear 11 and the lifting gear rod 12, the adsorption hollow pad 8 composed of the suction cup 15 and the heat-conducting adsorption member 8 The adsorption holes 803 opened on the top of 01 are adsorbed and connected to each other, and the heat-conducting bar 5 absorbs the heat of the busbar 2 and conducts it to the metal thermal spring 7. Through the principle of thermal expansion and contraction and the elastic vibration protection effect, the adsorption and fixation of the suction cup 15 and the thermal adsorption component 8 are stronger. At the same time, the elastic vibration of the metal thermal spring 7 continuously compresses the suction cup 15 and the adsorption hollow pad 801, and the convex thermal conductive sheet 802 is introduced into the adsorption hollow pad 801 to discharge the hot air, and dissipate the heat through the heat dissipation grille 18. This not only improves the fixing stability, reduces vibration wear, improves durability, but also improves the heat dissipation effect.

[0042] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
