Description

Technical Field

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

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has grown rapidly. In particular, the emergence of numerous high-rise buildings and large factory workshops has led to a sharp increase in electricity load. Traditional cables, as transmission conductors, can no longer meet the requirements of high current transmission. Busbar trunking, with its advantages of large capacity, convenient branching, and convenient bundled management, has gradually replaced wires and cables.

[0003] According to the content of the Chinese patent document with publication number CN222301370U, the interaction of the double-insulated protective busbar trunking body, the movable protective frame and the adjusting moving component makes it easier for the two ends of the double-insulated protective busbar trunking to be better protected after being connected during use, thereby improving its safety and making it more practical.

[0004] In this patent, although a movable protective frame is provided to protect the connection points at both ends of the busbar trunking, the adjustment and moving component used to move the movable protective frame is entirely located at the bottom of the busbar trunking. Furthermore, mechanisms to facilitate the movement of the movable protective frame are provided on both sides of the busbar trunking. This increases the overall size of the device, making it inconvenient to carry and install. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a high-efficiency insulated air busbar trunking, which solves the problem that the existing busbar trunking with movable protective frame is large in size and inconvenient to carry and install.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency insulated air busbar trunking, including a busbar trunking, a protective frame provided on the busbar trunking, the protective frame being slidably sleeved on the outside of the busbar trunking, which is used to protect the connection points at both ends of the busbar trunking; a plug-in assembly, the plug-in assembly having multiple sets, which are symmetrically distributed at the upper and lower ends of the outer walls on both sides of the busbar trunking, the plug-in assembly being used to plug and fix the slidable protective frame, the protective frame covering the plug-in assembly; and a pressing assembly, the pressing assembly having multiple sets, which are installed at the upper and lower ends of the outer walls on both sides of the protective frame, the pressing assembly being elastically inserted into the protective frame, which is used to press the plug-in assembly to separate the protective frame and the plug-in assembly.

[0007] Preferably, a U-shaped frame is fixedly installed on the outer wall of the busbar trunking at a location corresponding to the plug-in assembly. The plug-in assembly includes a first spring fixedly connected inside the U-shaped frame. The other end of the first spring is fixedly connected to a U-shaped cover. A plug is installed on the U-shaped cover. When the protective frame slides, the plug is squeezed by the inner surface of the protective frame.

[0008] Preferably, a movable hole is provided on the outer wall of the protective frame corresponding to the extrusion component, a T-shaped rod is movably inserted into the movable hole, and a second spring is sleeved on the outside of the T-shaped rod, the second spring being fixedly connected between the T-shaped rod and the outer wall of the protective frame.

[0009] Preferably, a T-shaped slider is fixedly provided in the middle of the inner surface of the two opposite sides of the protective frame, and a groove is provided on the outer wall of the busbar groove corresponding to the T-shaped slider, and the T-shaped slider is slidably installed in the groove.

[0010] Preferably, the busbar trunking has two horizontally fixedly connected insulating support plates inside. On the opposite side of the two insulating support plates, multiple grooves are equidistantly provided, and multiple conductive bars are connected to each groove in a corresponding manner.

[0011] Preferably, the conductive busbar is wrapped with an insulating layer.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0013] When this device achieves the sliding and fixing of the protective frame to protect the connection of the busbar trunking, the plug-in component and the extrusion component that achieve this effect are both located between the protective frame and the busbar trunking. The structure is concealed and does not occupy space outside the busbar trunking, reducing the overall size of the device and making it easy to carry and install. Attached Figure Description

[0020] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example 1

[0022] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, this utility model provides a high-efficiency insulated air busbar trunking, including a busbar trunking 1. A protective frame 5 is provided on the busbar trunking 1. The protective frame 5 is slidably sleeved on the outside of the busbar trunking 1 and is used to protect the connection points at both ends of the busbar trunking 1. Multiple sets of plug-in components 8 are symmetrically distributed at the upper and lower ends of the outer walls on both sides of the busbar trunking 1. The plug-in components 8 are used to plug and fix the slidable protective frame 5. The protective frame 5 covers the plug-in components 8. Multiple sets of extrusion components 10 are installed at the upper and lower ends of the outer walls on both sides of the protective frame 5. The extrusion components 10 are elastically inserted into the protective frame 5 and are used to extrude the plug-in components 8 to separate the protective frame 5 from the plug-in components 8.

[0023] A U-shaped frame 7 is fixedly installed on the outer wall of the busbar trough 1 at a position corresponding to the plug-in assembly 8. The plug-in assembly 8 includes a first spring 801 fixedly connected inside the U-shaped frame 7. The other end of the first spring 801 is fixedly connected to a U-shaped cover 802. A plug block 803 is installed on the U-shaped cover 802. When the protective frame 5 slides, the plug block 803 is squeezed by the inner surface of the protective frame 5.

[0024] A movable hole 9 is provided on the outer wall of the protective frame 5 at a position corresponding to the extrusion assembly 10. A T-shaped rod 1001 is movably inserted into the movable hole 9. A second spring 1002 is sleeved on the outside of the T-shaped rod 1001. The second spring 1002 is fixedly connected between the T-shaped rod 1001 and the outer wall of the protective frame 5.

[0025] T-shaped sliders 6 are fixedly provided in the middle of the inner surfaces of the two opposite sides of the protective frame 5. A sliding groove 601 is provided on the outer wall of the busbar trough 1 at the position corresponding to the T-shaped sliders 6. The T-shaped sliders 6 are slidably installed in the sliding groove 601.

[0026] In this embodiment, when both ends of the busbar trough 1 are connected to external electrical components, the protective frames 5 on both sides slide outwards. The protective frames 5 drive the T-shaped slider 6 to slide in the slide groove 601. During the movement of the protective frames 5, their inner surface continuously presses against the plug 803, causing the plug 803 to continuously compress the first spring 801. The first spring 801 has elastic potential energy for rebound. When the protective frame 5 slides to a position where it can no longer slide, the plug 803 contacts the movable hole 9 opened on the protective frame 5. At this time, the plug 803 is no longer compressed. Under the action of the first spring 801, it rebounds and drives the plug 803 to insert into the movable hole 9, thus fixing the protective frame 5. At this time, the position of the protective frame 5 is... The protective frame 5 is restricted and cannot slide further, thus protecting the connection of the busbar 1. When the protective frame 5 needs to be opened, the T-shaped rod 1001 is squeezed, which compresses the second spring 1002 and contacts the plug 803 to squeeze it. When the plug 803 is completely squeezed out of the movable hole 9, the plug 803 is separated from the protective frame 5, and the protective frame 5 can slide freely. When this device achieves the sliding and fixing of the protective frame 5 to protect the connection of the busbar 1, the plugging component 8 and the squeezing component 10 that achieve this effect are both set between the protective frame 5 and the busbar 1. The structure is concealed and does not occupy space outside the busbar 1, reducing the volume of the entire device and making it easy to move and install.

[0027] This embodiment can achieve the sliding and fixing of the protective frame 5 to protect the connection of the busbar trough 1, while the structure that achieves these effects is concealed between the protective frame 5 and the busbar trough 1, occupying space outside the busbar trough 1, reducing the size of the entire device, and making it easy to carry and install.

[0028] Example 2

[0029] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 As shown, in order to better realize this utility model, the following arrangement is adopted: In this embodiment, two insulating support plates 2 are fixedly connected horizontally inside the busbar trough 1. Multiple grooves are equally spaced on the opposite side of the two insulating support plates 2, and multiple conductive bars 3 are connected in corresponding order in the grooves.

[0030] The conductive busbar 3 is wrapped with an insulating layer 4.

[0031] In this embodiment, both the insulating support plate 2 and the insulating layer 4 are made of inorganic insulating materials. The insulating support plate 2 and the insulating layer 4 constitute a double insulation structure, which can achieve high-efficiency insulation.
