Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and more specifically, to a compact insulated bus duct. Background Art

[0002] A bus duct is a closed metal device, mainly composed of a protective housing formed by a cover plate and connecting side plates, a busbar system composed of busbars, insulating materials and related accessories, and according to the insulation method, it can be divided into three types: air type plug-in bus duct, compact insulated plug-in bus duct and high-strength plug-in bus duct, and is used to distribute relatively large power to each component of a decentralized system.

[0003] Most of the busbars of the existing compact bus ducts are fixedly installed in the protective housing through fastening bolts. This method requires workers to operate with auxiliary tools such as screwdrivers and wrenches during installation, which is time-consuming and laborious, and during the later maintenance of the busbars, both installation and disassembly are very inconvenient, reducing the maintenance work efficiency. Therefore, it is necessary to design a compact insulated bus duct to solve the above problems. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a compact insulated bus duct, which can achieve the effect of quickly and automatically installing the bus duct body without using screws.

[0006] Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A compact insulated bus duct includes a bus duct body, busbars are symmetrically installed at both ends of the bus duct body, a top plate is threadedly connected to the top of the bus duct body, card slots are symmetrically drilled at the top of the top plate, a protective cover is detachably connected in the card slots, and the protective cover covers the outer surface of the top plate. A clamping block is fixedly connected to the inner top wall of the protective cover, and the clamping block is engaged with the card slot. Sliding grooves are symmetrically drilled at both ends of the clamping block, and sliders are slidably connected in the sliding grooves. A compression spring is fixedly connected between the two sliders.

[0009] Furthermore, the top of the sliding groove is drilled to communicate with the protective cover, and clamping plates are symmetrically and fixedly connected to the sides of the tops of the two sliders close to each other, and the clamping plates extend outside the groove.

[0010] Furthermore, limiting grooves corresponding to the sliders are symmetrically drilled at both ends of the bus duct body, and the sliders are engaged with the limiting grooves.

[0011] Further, pins are symmetrically installed on the busbar trunk body on both sides of the limit groove, and two groups of clamping plates are installed on the busbar trunk body below the pins.

[0012] Further, slot holes are symmetrically drilled at both ends of the slider, and the pins are engaged with the slot holes.

[0013] Further, the distance between the conductive bar and the card slot is greater than the card block.

[0014] Further, a protective pad is fixedly connected to the bottom end of the card block, and the protective pad abuts against the top end of the conductive bar. Beneficial effects

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] (1) This solution can achieve that when installing and splicing the busbar trunk body, after aligning two busbar trunk bodies, the protective cover can be clamped at the connection of the two busbar trunk bodies. Then, hold two clamping plates and squeeze them against each other, compress and retract the slider into the chute through the compression spring, so that the card block is inserted into the card slot. At this time, the slider is located at the bottom of the card slot. Then release the clamping plates, and the sliders at both ends automatically pop out and abut and engage with the inner wall of the busbar trunk body, thereby fixing the top plate. It effectively achieves the effect of quickly and automatically installing the busbar trunk body without using screws.

[0017] (2) When splicing and installing the busbar trunk body, after covering the protective cover on the busbar trunk body, squeeze the clamping plate at this time to retract the slider into the chute, then insert the card block into the card slot and release the clamping plate. At this time, the slider automatically pops out and engages with the limit groove and protrudes outside the limit groove. Then, insert the pin into the slot hole by sliding and limit it through the clamping plate, thereby locking the position of the slider to prevent falling and sliding, and thus strengthening the splicing effect of the busbar trunk body.

A card block 7 is fixedly connected to the inner top wall of the protective cover 4, and the card block 7 is engaged with the card slot 3. Chutes 9 are symmetrically drilled at both ends of the card block 7, and sliders 8 are slidably connected in the chutes 9. A compression spring 11 is fixedly connected between the two sliders 8.

[0029] Please refer to Figure 1-2, a chute (9) is opened at the top end thereof and is communicated with the protective cover (4). On the side where the tops of two sliders (8) are close to each other, clamping plates (6) are symmetrically and fixedly connected. The clamping plates (6) extend outside the groove (5). At both ends of the busbar body (1), limiting grooves (13) corresponding to the sliders (8) are symmetrically opened. The sliders (8) are engaged with the limiting grooves (13). On the busbar body (1) on both sides of the limiting grooves (13), pins (15) are symmetrically installed. On the busbar body (1) below the pins (15), two groups of clamping plates (14) are installed. At both ends of the slider (8), slot holes (10) are symmetrically opened. The pins (15) are engaged with the slot holes (10). The distance between the conductive bar (12) and the clamping groove (3) is greater than that of the clamping block (7). The bottom end of the clamping block (7) is fixedly connected with a protective pad, and the protective pad abuts against the top end of the conductive bar (12). When the busbar body (1) is spliced and installed, after the protective cover (4) is covered on the busbar body (1), at this time, the clamping plates (6) are squeezed to retract the sliders (8) into the chute (9), and then the clamping blocks (7) are inserted into the clamping grooves (3), and then the clamping plates (6) are released. At this time, the sliders (8) automatically pop out and are engaged with the limiting grooves (13) and protrude outside the limiting grooves (13). At this time, the pins (15) are slid into the slot holes (10) and are limited by the clamping plates (14), so as to lock the positions of the sliders (8) and avoid falling off and sliding, thereby strengthening the assembly effect of the busbar body (1).

[0030] This solution can achieve that when the busbar body (1) is installed and spliced, the two busbar bodies (1) can be aligned, and then the protective cover (4) is clamped at the connection of the two busbar bodies (1). Subsequently, the two clamping plates (6) are held by hand and squeezed against each other, and the sliders (8) are compressed and retracted into the chute (9) through the compression springs (11), so that the clamping blocks (7) are inserted into the clamping grooves (3). At this time, the sliders (8) are located at the bottom of the clamping grooves (3). Then the clamping plates (6) are released, and the sliders (8) at both ends automatically pop out and abut and engage with the inner wall of the busbar body (1), so as to fix the top plate (2), effectively achieving the effect of quickly and automatically installing the busbar body (1) without using screws.
