Description

Technical Field

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

[0002] Busbar duct products on the market are categorized by process structure: they primarily include air-type busbar duct, epoxy resin-cast busbar duct, and compact busbar duct. Compact busbar duct typically features a "sandwich" structure, where the conductors are primarily insulated with insulating material. Several busbars are stacked seamlessly, tightly affixed to the outer casing. Insulation is primarily used to insulate the conductors from one another and from the outer casing. Compact busbar duct has become the leading product of busbar duct manufacturers in recent years due to its compact structure, faster heat dissipation, high current carrying capacity, and lighter weight, leading to increasingly fierce market competition.

[0003] Some of the existing dense bus ducts on the market are too large, occupying a large space for installation and transportation, and having high transportation and material costs; some dense bus ducts have different cover shapes for different current levels, are not universal, have a wide variety of materials, and are inconvenient to produce and process; some dense bus ducts have relatively small current levels, and due to the narrow width of the copper busbar and the small dimensions of the side panels, the distance between the upper and lower cover plates is smaller than the dimensions of the rivet gun head, and the rivet gun head cannot rivet during riveting; some dense bus ducts have low protection levels, and bus ducts with small current levels are difficult to fix; some dense bus ducts have problems such as no positioning when installing movable joints. Utility Model Content

[0004] The purpose of the utility model is to provide a compact and compact bus duct, which is used to solve the problems in the prior art mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compact and intensive bus duct, comprising two cover plates, a busbar arranged between the two cover plates, side plates arranged between the two cover plates and located on both sides of the busbar, two fixing components slidingly arranged on one of the cover plates, a pressure block arranged on the end of the cover plate, and a baffle arranged on the pressure block; the cover plates are C-shaped and the opening directions of the two cover plates are arranged in opposite directions, and U-shaped grooves are provided on both ends of the opposite side of the two cover plates, and the bottom of the fixing component is adapted to the U-shaped groove, four pressure blocks are provided and are respectively located at the two ends of the two cover plates, and two groups of baffles are respectively connected to the pressure blocks at the two ends of the two cover plates.

[0006] Furthermore, the fixing assembly includes a fixer and a fixing bracket, wherein two fixers are provided and are respectively located on both sides of one of the cover plates, the fixer is adapted to the bottom of the cover plate, the fixer is slidably fitted with the cover plate, and the fixing bracket is connected to the two fixers and fits with the upper part of the cover plate.

[0007] Furthermore, a groove is provided on the side panel, and a sealing strip is provided on the groove.

[0008] Furthermore, insulating pads are provided between both ends of the cover plate and the busbar, and a single-sided sponge rubber strip located between the two insulating pads is provided between the cover plate and the busbar.

[0009] Furthermore, an insulating layer is wrapped around the busbar.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The device reduces the size of the cover plate, and the size of accessories that match the cover plate, such as the end pressure plate, mounting bracket, joint cover plate, packaging box, etc., is also reduced, saving raw materials and reducing costs to solve the problem of large volume and high cost of existing intensive bus ducts.

[0012] 2. The device designs the cover plate into one specification, which is suitable for installation and use of busbars of different specifications at all current levels. It has strong versatility and is easy to purchase and process, so as to solve the problem of inconsistent shape and size of covers of different current levels in dense bus ducts and poor versatility.

[0013] 3. The cover of the device is provided with an inward recessed groove, which increases the effective distance between the upper and lower cover plates to meet the minimum distance of the riveting gun head, so as to solve the problem that the small current intensive bus duct cannot be riveted due to the small busbar width and small side plate shape, and the distance between the upper and lower cover plates is too small for the riveting gun head to enter during riveting.

[0014] 4. The device is equipped with sealing strips at the bent plate position of the side panels. When the upper and lower covers and the side panels are installed, the sealing strips are compressed, thereby improving the protection level of the dense bus duct. Insulating pads and sponge strips are installed between the end shell and the insulating side of the busbar to protect the conductor insulation layer from damage, thereby solving the problem of low protection level of dense bus duct and end insulation safety.

[0015] 5. The device is designed with a fixer that matches the cover plate, which is suitable for fixing plug-in boxes, T-shaped hangers, and spring brackets. It is easy to install and solves the problem of difficult fixation of dense bus ducts. BRIEF DESCRIPTION OF THE DRAWINGS
