Description

Technical Field

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

[0002] The dense bus duct is tightly attached to each other and to the shell, so it can withstand greater electric stress and thermal stress. It can also quickly dissipate the heat generated by the conductive bar, with a large current carrying capacity. The joints are fastened with insulating bolts and connected with double-connected copper bars, which effectively increases the contact area of ​​the joints and greatly reduces the temperature rise of the joints. The conductive bars of the dense bus duct are wrapped with flame-retardant cross-linked polyethylene heat shrink tubing, which has strong insulation performance and no toxic gas is emitted in case of fire. The dense bus duct plug interface is flexible and convenient to set, and a large number of sockets can be set, with strong versatility. When adjusting the position of electrical equipment, there is no need to change the power supply system.

[0003] A compact and intensive bus duct disclosed in Chinese patent CN219739900U resets two fixed blocks through the elastic force of two springs, and then the two fixed blocks are respectively stuck in the interior of two moving rods to complete the fixation of the first intensive bus duct body and the second intensive bus duct body, which is convenient for quickly assembling the first intensive bus duct body and the second intensive bus duct body, improving the convenience of assembling the first intensive bus duct body and the second intensive bus duct body, and improving the speed of assembling the first intensive bus duct body and the second intensive bus duct body. However, while solving the problem, the compact and intensive bus duct has the following defects:

[0004] When the dense bus duct is installed in a building, power transmission is achieved by connecting multiple dense bus ducts end to end. Therefore, during use, if a dense bus duct is damaged and needs to be disassembled and replaced, since the fixing plate is fixedly installed on the first dense bus duct body and the fixing sleeve is fixedly installed on the second dense bus duct body, the damaged dense bus duct is restricted by the dense bus ducts on both sides and cannot move. Therefore, the fixing plate cannot be detached from the fixing sleeve, resulting in the damaged dense bus duct cannot be disassembled and replaced separately, which brings great inconvenience to the subsequent maintenance. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0006] To this end, one purpose of the utility model is to provide a compact bus duct, aiming to solve the problem of inconvenient later maintenance of the compact and compact bus duct in the prior art.

[0008] Preferably, any of the above schemes is that the shell is fixedly connected with a slide groove at two ends, and the slide groove is internally connected to a fixing plate, and the shell is fixedly connected with a threaded tube at two ends, and an avoidance groove is opened on the fixing plate near the shell, and the internal thread of the threaded tube is connected with a stud at one end of the stud, and one end of the stud is fixedly connected with a positioning shaft, and a cross groove is opened at the center of one side of the positioning shaft, and a positioning hole is opened on one side of the fixing plate at a position corresponding to the avoidance groove, and the positioning shaft is inserted in the positioning hole.

[0009] Preferably, any of the above schemes has bevel angles on the top, sides and bottom of the conductive plate to facilitate clamping of the conductive plate on the surface of the end of the busbar.

[0010] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0011] 1. When pulling out the damaged intensive bus duct, the positioning plate of the adjacent intensive bus duct will not affect the removal of the busbar of the damaged intensive bus duct. Therefore, a certain intensive bus duct can be disassembled and replaced separately, ensuring easy assembly and facilitating subsequent maintenance.

[0012] 2. By providing bevel angles on the top, sides and bottom of the conductive plate, the bevel angles can play a guiding role, making it easier to align the busbar with the conductive plate, further facilitating assembly.

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-6As shown, a dense bus duct of this embodiment includes a shell 1, a plurality of bus bars 2 are fixed inside the shell 1, and the outer surface of the bus bar 2 is provided with insulating material for isolation. The plurality of bus bars 2 are fixed side by side inside the shell 1, and both ends of the bus bar 2 protrude from the outside of the shell 1, and are used to connect multiple dense bus ducts. A positioning plate 3 is fixedly connected to the top of the shell 1, and a conductive plate 4 is fixedly connected to the bottom of the positioning plate 3. The conductive plates 4 are provided in multiple groups, and the number of groups is the same as the number of bus bars 2, and each group includes two conductive plates 4, a portion of the top of the conductive plate 4 is fixedly connected to the positioning plate 3, and the other portion protrudes from one side of the positioning plate 3, as shown in FIG. Figure 3 As shown, the portion of the conductive plate 4 protruding from one side of the positioning plate 3 is used to connect with the tail of the adjacent dense bus duct, and a portion of the conductive plate 4 is in contact with the bus bar 2 below the positioning plate 3, as shown in FIG. Figure 2 As shown, the conductive plate 4 is attached to the busbar 2 to achieve power transmission.

[0025] Specifically, the housing 1 is fixedly connected with a slide groove 11 on both sides, and a fixed plate 5 is slidably connected inside the slide groove 11. The housing 1 is fixedly connected with a threaded cylinder 51 on both sides, and a side of the fixed plate 5 close to the housing 1 is provided with an avoidance groove 52. When the fixed plate 5 is sliding, the threaded cylinder 51 passes through the avoidance groove 52, so that the threaded cylinder 51 does not affect the sliding of the fixed plate 5.

[0026] Furthermore, the internal thread of the threaded barrel 51 is connected with a stud 6, one end of the stud 6 is fixedly connected with a positioning shaft 61, and a cross slot 62 is opened at the center of one side of the positioning shaft 61. By inserting a screwdriver into the cross slot 62 and rotating the positioning shaft 61, the stud 6 and the positioning shaft 61 can be completely retracted into the interior of the threaded barrel 51, so that the positioning shaft 61 will not affect the sliding of the fixed plate 5.

[0027] Furthermore, a positioning hole 53 is opened on one side of the fixing plate 5 at a position corresponding to the avoidance groove 52. The fixing plate 5 is slid to align the positioning hole 53 with the threaded tube 51. The positioning shaft 61 is rotated by inserting a screwdriver into the cross slot 62 so that the positioning shaft 61 protrudes from the outside of the threaded tube 51, thereby allowing the positioning shaft 61 to be inserted into the positioning hole 53. The fixing plate 5 can then be positioned so that it cannot slide.

[0028] Further, such as Figure 2 and Figure 6As shown, one end of the slide slot 11 is fixedly connected to a support plate 7, one side of the support plate 7 is provided with a hole slot 71, the interior of the hole slot 71 is inserted with a limit block 72, one end of the limit block 72 is fixedly connected to a pull plate 73, a spring 74 is fixedly connected between the pull plate 73 and the support plate 7, when the pull plate 73 is pulled outward, the spring 74 stretches, and the limit block 72 can be retracted to the inside of the hole slot 71, when the pull plate 73 is released, the spring 74 rebounds, and the limit block 72 protrudes from one side of the support plate 7, and the end of the limit block 72 away from the pull plate 73 is provided with a chamfer.

[0029] Furthermore, a limiting hole 54 is opened on one side of the fixing plate 5. When the two dense bus ducts are connected end to end, the fixing plate 5 is inserted into the tail end of the adjacent dense bus duct slide groove 11, and the fixing plate 5 contacts the chamfer of the limiting block 72, so that the limiting block 72 shrinks into the hole groove 71. When the position of the limiting block 72 corresponds to the position of the limiting hole 54, the spring 74 rebounds and pushes the limiting block 72 to move through the pulling plate 73, so that the limiting block 72 is inserted into the inside of the limiting hole 54, thereby completing the end-to-end connection of the two dense bus ducts.

[0030] Specifically, Figure 3 As shown, the top, side and bottom of the conductive plate 4 are provided with slope angles 41, so as to facilitate the conductive plate 4 to be sleeved on the end of the busbar 2 of another intensive busbar duct.

[0031] The working principle of the utility model is as follows: when in use, after the first intensive bus duct is fixed, the head of the second intensive bus duct corresponds to the tail of the first intensive bus duct, and then the fixing plates 5 on both sides of the head of the second intensive bus duct are inserted into the slide groove 11 of the first intensive bus duct. At this time, the part of the conductive plate 4 protruding on one side of the positioning plate 3 is sleeved on the end of the bus bar 2 at the tail of the first intensive bus duct to realize power transmission. After the limiting hole 54 on the fixing plate 5 corresponds to the limiting block 72 on the support plate 7, the spring 74 will pull the pull plate 73 to make the limiting block 72 inserted in the limiting hole 54, completing the connection of the two intensive bus ducts;

[0032] When a dense bus duct is damaged and needs to be disassembled and replaced, use a screwdriver to insert the cross slot 62 on the damaged dense bus duct, rotate the stud 6, and make the positioning shaft 61 enter the threaded tube 51, then pull the pull plate 73, the time limit block 72 disengages from the limit hole 54, and then slide the fixing plate 5 to make it disengage from the front dense bus duct. The same operation is performed to remove the fixing plate 5 at the tail of the damaged dense bus duct. At this time, the dense bus duct is not interfered with by other structures, and the damaged dense bus duct can be pulled outward for replacement.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. By setting a positioning plate 3, and fixing a conductive plate 4 on the positioning plate 3, and a part of the conductive plate 4 protruding from one side of the positioning plate 3, after several dense bus ducts are connected, if a dense bus duct is damaged, after disassembling the fixing plates 5 at the head and tail, when the damaged dense bus duct is pulled out, the positioning plate 3 of the adjacent dense bus duct will not affect the pulling out of the busbar 2 of the damaged dense bus duct. Therefore, a dense bus duct can be disassembled separately for replacement, which ensures that it is easy to assemble and facilitates later maintenance.

[0035] 2. By providing slope angles 41 on the top, sides and bottom of the conductive plate 4, when the conductive plate 4 is sleeved on the end of the busbar 2 of another dense bus duct, the slope angle 41 can play a guiding role, making it easier to align the busbar 2 with the conductive plate 4, further facilitating assembly.
