Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a densely insulated busbar. Background Technology

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbar columns. Modern high-rise buildings and large workshops require huge amounts of electrical energy, and to meet the powerful current of hundreds or thousands of amperes required for this huge load, safe and reliable transmission equipment must be selected. Busbar systems are a good choice. Dense insulated busbar trunking is an auxiliary device used in power distribution equipment in industrial and mining areas and high-rise buildings.

[0003] In the prior art, the shell of the insulated dense busbar trunking is usually rigidly connected to the busbars. During transportation and installation, the busbar trunking is easily damaged by vibration.

[0004] Therefore, it is necessary to propose a densely insulated busbar trunking system to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a densely insulated busbar trunking to solve the problem that in the prior art, the shell and busbar of the densely insulated busbar trunking are usually rigidly connected, which makes the busbar trunking easily damaged by vibration during transportation and installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a densely insulated busbar trunking, including a protective shell, a conductive busbar inside the protective shell, insulating rubber blocks at both ends of the protective shell, through slots for the conductive busbar to pass through the insulating rubber blocks, and retaining strips at both the upper and lower ends inside the insulating rubber blocks, with a retaining groove for positioning the conductive busbar on the side of the retaining strip near the conductive busbar. After installation, the conductive busbar is limited by the retaining strips and the retaining groove.

[0007] Preferably, both ends of the protective shell are provided with sealing plate assemblies. The sealing plate assembly includes side sealing plates. There are two side sealing plates, which are fixedly connected to the protective shell. The two side sealing plates are respectively distributed on both sides of the protective shell. The side sealing plates are provided with threaded holes, and bolts are threaded into the internal threads of the threaded holes.

[0008] Preferably, a round rod is fixedly connected to the side of the card strip facing away from the inner cavity of the protective shell.

[0009] Preferably, a vertical plate is provided on the side of the side sealing plate near the insulating rubber block, and an extrusion block is fixedly connected to the side of the vertical plate facing away from the corresponding side sealing plate.

[0023] This utility model provides, for example Figures 1-5 The densely insulated busbar trunking shown includes a protective housing 1. Conductive bars 4 are provided inside the protective housing 1. Multiple conductive bars 4 are provided. Insulating rubber blocks 5 are provided at both ends of the protective housing 1. Through slots 6 are provided on the insulating rubber blocks 5 for the conductive bars 4 to pass through. The insulating rubber blocks 5 are made of insulating rubber material and have a certain degree of elasticity.

[0024] Considering that existing densely insulated busbar trunking typically has a rigid connection between the protective housing 1 and the conductive busbar 4, it is prone to damage during transportation and installation. However, this utility model achieves shock absorption during transportation and installation by setting an insulating rubber block 5 to cooperate with the conductive busbar 4.

[0025] Considering that the conductive busbar 4 needs to be fixed after the installation of the dense insulated busbar trunking to prevent loosening, locking strips 7 are provided at both the upper and lower ends inside the insulating rubber block 5. The side of the locking strip 7 near the conductive busbar 4 is provided with a slot 8 for positioning the conductive busbar 4. After installation, the locking strips 7 at both the upper and lower ends inside the insulating rubber block 5 move towards each other, and the conductive busbar 4 is squeezed and positioned by the slot 8, thereby improving the safety performance of the dense insulated busbar trunking.

[0026] Both ends of the protective housing 1 are provided with sealing plate assemblies. The sealing plate assembly includes side sealing plates 2. There are two side sealing plates 2. The side sealing plates 2 are fixedly connected to the protective housing 1. The two side sealing plates 2 are respectively distributed on both sides of the protective housing 1. The side sealing plates 2 are provided with threaded holes 3. The threaded holes 3 are connected to bolts 15 by threads. The bolts 15 are made of insulating materials, such as epoxy resin.

[0027] With the side sealing plate 2 and bolts 15 installed, when the busbar trunking is plugged into the power distribution equipment, the bolts 15 can be used to fix the busbar trunking to the power distribution equipment, thereby improving the stability of the busbar trunking.

[0028] To control the position of the clip 7, a round rod 11 is fixedly connected to the side of the clip 7 facing away from the inner cavity of the protective shell 1. There are two round rods 11, which are distributed at both ends of the clip 7. The insulating rubber block 5 has a round hole for the round rod 11 to pass through.

[0029] A vertical plate 12 is provided on the side of the side sealing plate 2 near the insulating rubber block 5. An extrusion block 13 is fixedly connected to the side of the vertical plate 12 facing away from the corresponding side sealing plate 2. Two extrusion blocks 13 are provided, distributed at both ends of the vertical plate 12. The sides of the two extrusion blocks 13 that are close to each other are inclined. (Refer to...) Figure 3 The width of the extrusion block 13 gradually decreases in the direction away from the vertical plate 12, and the extrusion block 13 cooperates with the corresponding round rod 11.

[0030] When the vertical plate 12 moves away from the corresponding side sealing plate 2, it will drive the extrusion block 13 to move synchronously. The extrusion block 13 abuts against the corresponding round rod 11. Since the side of the two extrusion blocks 13 that are close to each other is set in an inclined shape, the locking strips 7 at the upper and lower ends inside the insulating rubber block 5 move towards each other.

[0031] A horizontal plate 14 is fixedly connected to the side of the vertical plate 12 facing away from the insulating rubber block 5, and the horizontal plate 14 is rotatably connected to the corresponding bolt 15. A square frame 9 is fixedly connected to the outside of the insulating rubber block 5, and the square frame 9 is fixedly connected to the inside of the protective shell 1 by screws 10.

[0032] Specifically, after installation, i.e., when the busbar trunking and the power distribution equipment are connected, the bolt 15 is rotated and moved towards the conductive busbar 4. The bolt 15 is used to fix the busbar trunking and the power distribution equipment together, improving the stability of the busbar trunking. At the same time, when the bolt 15 drives the vertical plate 12 to move away from the corresponding side sealing plate 2 through the horizontal plate 14, it will drive the pressing block 13 to move synchronously. The pressing block 13 and the corresponding round rod 11 abut against each other, so that the locking strips 7 at the upper and lower ends inside the insulating rubber block 5 move towards each other, and the conductive busbar 4 is pressed and positioned through the locking groove 8.

[0033] Furthermore, the movement distance of the card strip 7 is appropriate, and it will not excessively compress the conductive busbar 4.

[0034] By setting up structures such as vertical plate 12 and horizontal plate 14, after installation, when the busbar trunking and power distribution equipment are fixed together, the locking strips 7 at the upper and lower ends inside the insulating rubber block 5 can move towards each other, thereby improving the efficiency of use.
