It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. At present, most bus duct vertical elbows adopt a welded structure. The bus duct elbows with this structure have defects: the existing bus duct elbows are an integrated structure, and the two groups of conductors need to be connected by welding separately. This structure has high labor intensity and cannot guarantee the welding quality of the weld. It has high contact resistance, is easy to heat up, has huge hidden dangers, is difficult to maintain, and it is difficult to guarantee the basic requirements of users for the continuity of power supply in the power system. Therefore, it is urgent to propose a bus duct elbow that can be quickly disassembled and assembled. Summary of the invention

[0006] The conductive bar connector includes a connector shell, which is an L-shaped bent pipe structure. An insulating plate is provided inside the connector shell. The two ends of the L-shape of the connector shell are two ports, and the two ports are respectively used for inserting conductive bars on two linear bus ducts. The insulating plate separates and contacts the two inserted conductive bars. The two ports of the connector shell are respectively fixedly connected to the shell of the corresponding linear bus duct through a flange connection structure.

[0007] To further define the above scheme, the linear bus duct includes a conductive bar, an insulating shell and a protective shell, the conductive bar is wrapped with an insulating shell on the outside, the insulating shell is protected by a protective shell on the outside, and one end of the conductive bar is exposed for connection.

[0008] To further define the above scheme, the flange connection structure includes a connecting flange I and a connecting flange II, a connecting flange I is arranged on the connector housing port in the conductive bar connector, a connecting flange II is arranged on the protective housing end of the linear bus duct, and the connecting flange I and the connecting flange II are connected by connecting bolts.

[0009] As a further limitation of the above solution, a plurality of insulating plates are arranged inside the connector housing according to the number of conductive sheets in the conductive row, the insulating plates are arranged parallel to each other, and one side of the insulating plate is connected to the inner wall of the connector housing.

[0010] As a further limitation of the above solution, one side of each of the insulating plates is fixedly connected to the inner wall of the connector housing.

[0011] As a further limitation of the above solution, one side of the insulating plate is connected to the inner wall of the connector housing through a sliding structure.

[0012] To further define the above scheme, the sliding structure used for connecting the insulating plates includes a connecting slide plate, both ends of which are fixed on the two side walls of the connector housing, the insulating plates are provided with through holes, and several insulating plates are passed through the connecting slide plate.

[0013] As a further limitation of the above solution, the shape of the perforations on the insulating plate is the same as the cross-sectional shape of the connecting slide plate.

[0014] To further define the above scheme, the connection structure of the connecting skateboard on the two side walls of the connector shell is as follows: a skateboard support hole is provided on one side wall of the connector shell, and the shape of the skateboard support hole is the same as the cross-sectional shape of the connecting skateboard; a screw through hole is provided on the other side wall of the connector shell opposite to the connecting skateboard; a limiting head is provided at one end of the connecting skateboard, and a threaded connection hole is provided at the other end of the connecting skateboard; the connecting skateboard is inserted into the skateboard support hole and one end is limited by the limiting head; the other end of the connecting skateboard is fixed by a fixing screw, and the fixing screw passes through the screw through hole and is tightened with the threaded connection hole.

[0018] 2. In this solution, since one side of several insulating plates is fixedly connected to the inside of the connector housing, the insulating plates are suspended and have elastic adjustment performance. By arranging the clamping components on both sides of the connector housing, the insulating plates can clamp the two conductive bars, so that the two conductive bars are in close contact, thereby improving the performance of the conductor;

[0029] Example 1: A bus duct elbow with a quick disassembly structure, see Figure 1 As shown, it comprises two straight bus ducts 1 and a conductive bar connector 2, and one end of each straight bus duct 1 is provided with a conductive bar 1-3 exposed to the outside.

[0030] The conductive bar connector 2 includes a connector shell 2-1, which is an L-shaped bent pipe structure. An insulating plate 2-2 is provided inside the connector shell 2-1. The two ends of the L-shape of the connector shell 2-1 are two ports, and the two ports are respectively used for inserting the conductive bars 1-3 on the two linear bus ducts 1. The insulating plate 2-2 separates and contacts the two inserted conductive bars 1-3. The two ports of the connector shell 2-1 are respectively fixedly connected to the shell of the corresponding linear bus duct 1 through a flange connection structure 3.

[0031] In a specific implementation: see Figure 2 As shown, the linear bus duct 1 includes a conductive bar 1-3, an insulating shell 1-2 and a protective shell 1-1. The outside of the conductive bar 1-3 is wrapped by the insulating shell 1-2, the outside of the insulating shell 1-2 is protected by the protective shell 1-1, and one end is exposed for connection.

[0032] For details, see Figure 2 As shown, a plurality of insulating plates 2-2 are arranged inside the connector housing 2-1 according to the number of conductive sheets in the conductive bar 1-3. The insulating plates 2-2 are arranged in parallel with each other, and one side of the insulating plates 2-2 is connected to the inner wall of the connector housing 2-1. After two conductive bars 1-3 are inserted, the conductive sheets on the two conductive bars 1-3 facing each other are respectively clamped in the space formed by the adjacent insulating plates 2-2.

[0033] In a specific implementation: see Figure 2As shown, the flange connection structure 3 includes a connecting flange I3-1 and a connecting flange II3-2. A connecting flange I3-1 is arranged on the port of the connector housing 2-1 in the conductive bar connector 2, and a connecting flange II3-2 is arranged on the end of the protective housing 1-1 on the linear bus duct 1. The connecting flange I3-1 and the connecting flange II3-2 are connected by connecting bolts 3-3.

[0034] In this embodiment, the bus duct elbow is composed of two linear bus ducts and a conductive bar connector, wherein the two ports of the connector housing are respectively fixedly connected to the housings of the corresponding linear bus ducts through a flange connection structure. Due to the use of the flange connection structure, not only is the connection quality reliable, but it is also easy to disassemble and maintain, has a small size, and is easy to transport.

[0035] Example 2: See Figure 2 As shown, one side of each insulating plate 2-2 is fixedly connected to the inner wall of the connector housing 2-1 by means of bolts or the like.

[0036] Both sides of the connector housing 2-1 are provided with a tightening component 4 for tightening a plurality of insulating plates 2-2 from both sides. The tightening component 4 includes a tightening screw 4-1. Both side walls of the connector housing 2-1 are provided with a tightening screw hole 4-2. The tightening screw 4-1 is screwed into and passed through the tightening screw hole 4-2 to press against the insulating plates 2-2 on both sides.

[0037] In this embodiment, since one side of several insulating plates is fixedly connected to the inside of the connector housing, the insulating plates are suspended and have elastic adjustment performance. By arranging tightening components on both sides of the connector housing, the insulating plates can clamp the two conductive bars so that the two conductive bars are in close contact, thereby improving the performance of the wires.

[0038] Embodiment 3: One side of the insulating plate 2 - 2 is connected to the inner wall of the connector housing 2 - 1 via a sliding structure 5 .

[0039] For details, see Figure 3 As shown, the sliding structure 5 used for connecting the insulating plate 2-2 includes a connecting slide 5-1, both ends of which are fixed on the two side walls of the connector housing 2-1, and a through hole 5-3 is provided on the insulating plate 2-2, and several insulating plates 2-2 are passed through the connecting slide 5-1 through the through hole 5-3.

[0040] Preferably, see Figure 4 As shown, the shape of the through hole 5-3 on the insulating plate 2-2 is the same as the cross-sectional shape of the connecting slide plate 5-1.

A screw through hole 5-7 is provided on the other side wall of the connector shell 2-1. A limiting head 5-2 is provided at one end of the connecting skateboard 5-1, and a threaded connection hole 5-4 is provided at the other end of the connecting skateboard 5-1. The connecting skateboard 5-1 passes through the skateboard support hole 5-6 and one end is limited by the limiting head 5-2. The other end of the connecting skateboard 5-1 is fixed by a fixing screw 5-5, and the fixing screw 5-5 passes through the screw through hole 5-7 and is tightened with the threaded connection hole 5-4.

[0042] In this embodiment, several insulating plates are connected to the inside of the connector housing through a sliding structure. The insulating plates are passed through the connecting slide plate of the sliding structure and cannot rotate but can only slide. Therefore, under the action of the tightening components on both sides, each insulating plate can be tightly pressed, further ensuring that the two conductive bars are in close contact, thereby improving the performance of the wires.
