Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar with an external fireproof partition assembly. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars, used to distribute large amounts of power to various components in a distributed system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Patent CN209730740U discloses a safe and stable enclosed busbar trunking system, comprising an enclosed enclosure and connectors. The enclosed enclosure includes a U-shaped groove, a cover plate disposed on the U-shaped groove, connectors disposed at both ends of the U-shaped groove, and busbar conductors disposed within the U-shaped groove. Clamping plates forming the groove are disposed on both sides of the U-shaped groove, and a bent portion extending to both sides is disposed at the upper end of the U-shaped groove. Fitting portions extend upward from both ends of the cover plate. By providing fitting portions on the cover plate to fix the U-shaped groove, and bending portions on the U-shaped groove to fit the fitting portions, the structural strength of the enclosed enclosure is improved after assembly. Furthermore, by providing two clamping plates on both sides of the U-shaped groove for holding the connectors, and by fixing the connectors with the two clamping plates, adjacent enclosed enclosures can be connected, and the required number of enclosed enclosures can be added sequentially as needed.

[0004] However, the aforementioned safe and stable enclosed busbar trunking still has the following shortcomings:

[0005] When inspecting or replacing the internal parts of the busbar trunking in the above-mentioned device, it is necessary to remove several screws one by one to open the outer casing, which is time-consuming and labor-intensive and affects the efficiency of inspection and replacement. In view of this, we propose a busbar trunking with an external fireproof partition assembly. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a busbar trunking with an external fireproof partition assembly. This solves the technical problem that when repairing or replacing the internal parts of the busbar trunking in the current device, it is necessary to remove several screws one by one to open the outer shell, which is time-consuming and labor-intensive and affects the efficiency of repair and replacement.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a busbar trunking for an external fireproof partition assembly, including a housing, a plurality of conductive busbars inserted inside the housing, and a set of auxiliary components symmetrically arranged on the surface of the housing;

[0008] The outer shell includes a lower shell, a set of guide grooves symmetrically opened inside the lower shell, an upper shell attached to the upper shell, a set of guide plates symmetrically fixed at the bottom of the upper shell, a set of cylindrical frames symmetrically fixed on both sides of the surface of the lower shell, a U-shaped locking rod penetrating inside the set of cylindrical frames on the same side, a set of limiting ring plates symmetrically fixed on the surface of the U-shaped locking rod, and a spring provided on one side of the limiting ring plate.

[0009] Preferably, the upper housing and the lower housing form a locking structure through a guide plate and a guide groove, with the guide plate fitting into the guide groove.

[0010] Preferably, the end of the U-shaped lever passes through one side of the lower housing and enters the guide groove, and the guide plate has a slot inside that matches the end of the U-shaped lever.

[0011] Preferably, the U-shaped clamp rod is formed into an elastic structure by a limiting ring plate, a spring, and a cylindrical frame, and the outer wall of the limiting ring plate is in contact with the large-diameter inner wall of the cylindrical frame.

[0012] Preferably, the auxiliary component includes a limiting groove, which is formed on the surface of the outer shell. A protective frame is engaged inside the limiting groove. A set of screws symmetrically penetrates both sides of the protective frame. A heat dissipation fin is fixedly embedded in the middle of the inner side of the protective frame.

[0013] Preferably, the protective frame has a partially convex cross-section, the protective frame is detachable from the outer shell by screws, and both the inner and outer surfaces of the protective frame are coated with a fire-retardant coating.

[0014] Preferably, the heat dissipation fins are aluminum alloys with anodized surfaces, the oxide film thickness of the heat dissipation fins is ≤10μm, and the heat dissipation fins are wavy.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model effectively separates the end of the U-shaped clamp from the guide plate by moving the U-shaped clamp outward. At this time, the guide plate is unrestricted and can move directly upward, thereby driving the upper shell and the lower shell to separate, improving disassembly efficiency and facilitating the inspection and replacement of internal parts of the shell. When assembling the upper shell and the lower shell, the guide plate is inserted into the guide groove based on the outward movement of the U-shaped clamp. Then, the U-shaped clamp is released. Under the influence of the spring rebound force, the end of the U-shaped clamp pops out and effectively engages inside the guide plate, thereby realizing the rapid positioning of the guide plate and thus quickly realizing the assembly between the upper shell and the lower shell.

[0017] 2. In this utility model, the outer shell and the protective frame are connected. The heat generated by the internal parts of the outer shell is efficiently dissipated through the wave-shaped heat dissipation fins. At the same time, the protective frame with a fire-retardant coating and the heat dissipation fins with an oxide film give the auxiliary components good fire resistance and improve safety. The protective frame and heat dissipation fins can be removed from the outer shell by unscrewing the screws, making it easy to replace the protective frame and heat dissipation fins.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] A busbar trunking for an external fireproof partition assembly, see [link / reference]. Figures 1 to 5 It includes a housing 1, with several conductive bars 2 inserted inside the housing 1, and a set of auxiliary components 3 symmetrically arranged on the surface of the housing 1;

[0028] The outer shell 1 includes a lower shell 101, with a set of guide grooves 102 symmetrically formed inside the lower shell 101. An upper shell 103 is attached to the upper shell 101, and a set of guide plates 104 are symmetrically fixed to the bottom of the upper shell 103. The upper shell 103 and the lower shell 101 form a locking structure through the guide plates 104 and the guide grooves 102. The guide plates 104 are fitted into the guide grooves 102. A set of cylindrical frames 105 are symmetrically fixed to both sides of the surface of the lower shell 101, and a U-shaped locking rod 1 passes through the cylindrical frame 105 on the same side. 06. Furthermore, the end of the U-shaped clamp 106 passes through one side of the lower housing 101 and enters the guide groove 102. The guide plate 104 has a groove inside that matches the end of the U-shaped clamp 106. A set of limiting ring plates 107 are symmetrically fixedly sleeved on the surface of the U-shaped clamp 106. A spring 108 is provided on one side of the limiting ring plate 107. Furthermore, the U-shaped clamp 106 forms an elastic structure with the cylinder frame 105 through the limiting ring plate 107, the spring 108, and the outer wall of the limiting ring plate 107 fits against the large-diameter inner wall of the cylinder frame 105. This utility model effectively disengages the end of the U-shaped locking rod 106 from the guide plate 104 by moving the U-shaped locking rod 106 outward. At this time, the guide plate 104 is unrestricted and can move directly upward, thereby driving the upper housing 103 to separate from the lower housing 101, improving disassembly efficiency and facilitating the inspection and replacement of internal parts of the outer shell 1. When assembling the upper housing 103 and the lower housing 101, the guide plate 104 is inserted into the guide groove 102 based on the outward movement of the U-shaped locking rod 106. Then, the U-shaped locking rod 106 is released. Under the influence of the spring 108's rebound force, the end of the U-shaped locking rod 106 pops out and effectively engages inside the guide plate 104, thereby achieving rapid positioning of the guide plate 104 and quickly realizing the assembly between the upper housing 103 and the lower housing 101.

[0029] It is worth noting that the auxiliary component 3 includes a limiting groove 301, which is formed on the surface of the outer shell 1. A protective frame 302 is engaged inside the limiting groove 301. A set of screws 303 are symmetrically inserted through both sides of the protective frame 302. The protective frame 302 has a partial cross-section that is convex. The protective frame 302 and the outer shell 1 are detachable through the screws 303. The inner and outer surfaces of the protective frame 302 are coated with a fire-retardant coating. A heat dissipation fin 304 is fixedly embedded in the middle of the inner side of the protective frame 302. Furthermore, the heat dissipation fin 304 is made of aluminum alloy with an oxidized surface. The oxide film thickness of the heat dissipation fin 304 is ≤10μm, and the heat dissipation fin 304 is wavy. In this utility model, the outer shell 1 and the protective frame 302 are connected. The heat generated by the internal parts of the outer shell 1 is efficiently dissipated through the wave-shaped heat dissipation fins 304. At the same time, the protective frame 302 with a fire-retardant coating and the heat dissipation fins 304 with an oxide film give the auxiliary component 3 good fire resistance and improve safety. The protective frame 302 and the heat dissipation fins 304 can be removed from the outer shell 1 by removing the screws 303, which makes it easy to replace the protective frame 302 and the heat dissipation fins 304.

[0030] Working principle: By moving the U-shaped lever 106 outward, the end of the U-shaped lever 106 is disengaged from the guide plate 104. At this time, the guide plate 104 is unrestricted and can move directly upward, thereby driving the upper housing 103 to separate from the lower housing 101, improving disassembly efficiency and facilitating the inspection and replacement of internal parts of the outer shell 1. When assembling the upper housing 103 and the lower housing 101, the guide plate 104 is inserted into the guide groove 102 based on the outward movement of the U-shaped lever 106. Then, the U-shaped lever 106 is released, and the end of the U-shaped lever 106 pops out and engages with the guide plate due to the rebound force of the spring 108. Inside 104, the guide plate 104 is quickly positioned, thereby quickly assembling the upper housing 103 and the lower housing 101. The heat generated by the internal parts of the outer shell 1 is efficiently dissipated through the wave-shaped heat dissipation fins 304. At the same time, the protective frame 302 with a fire-retardant coating and the heat dissipation fins 304 with an oxide film give the auxiliary component 3 good fire resistance and improve safety. The protective frame 302 and the heat dissipation fins 304 can be removed from the outer shell 1 by removing the screws 303, making it easy to replace the protective frame 302 and the heat dissipation fins 304.
