[0025] The effect achieved by the whole embodiment 1 is that: by adopting the modular design concept, the air opening copper bar is divided into multiple independent modules, in the actual electrical installation process, only the embedding block 4 of the two adjacent copper bar bodies 2 is accurately inserted into the adjacent embedding groove 3, the tight connection of the two copper bar modules can be easily realized, this way can flexibly assemble and adjust the length of the copper bar according to the actual installation demand, so as to perfectly adapt to various different electrical layout and power requirements, compared with the traditional way of cutting the copper bar to adapt to different lengths, the modular design not only avoids the waste of materials, but also greatly improves the installation efficiency and flexibility, and the embedding block 4 and the embedding groove 3 are the same size, and the embedding block 4 and the copper bar body 2 are made of excellent conductive purple copper material, so the conductive performance of the two copper bar bodies 2 will not be affected after connection, and in the butt joint process, the two copper bar modules can be tightly combined together to form a stable mortise and tenon structure through the elastic clamping assembly and the threaded fixing assembly, which not only ensures the stability of the connection, but also enables the two copper bar modules to maintain good conductive performance and stability during long-term use, in addition, the fixing way of this modular design is very fast and convenient, which greatly reduces the operation difficulty, so that the installation process is more efficient and convenient.

[0026] Embodiment 2, as shown in Figures 2-4 The inner walls of the three fixed frames 11 are each provided with a group of sliding grooves 12, the inner walls of the three groups of sliding grooves 12 are each slidably embedded with a sliding plate 13, the top of the three groups of first limiting blocks 10 is fixedly connected with the bottom of the three sliding plates 13, the top of the three fixed frames 11 is provided with a threaded groove 14, the inner wall of the three threaded grooves 14 is threadedly connected with an adjusting screw 15, the top of the three adjusting screws 15 is fixedly connected with a knob 16, the outer wall of the three adjusting screws 15 is fixedly sleeved with a bearing 17, and the outer wall of the three bearings 17 is fixedly inserted into the inside of the three sliding plates 13, the outer wall of the two protective shells 1 and the second protective cover 6 is provided with a second clamping groove 18, the outer wall of the two protective shells 1 and the first protective cover 5 is fixedly connected with a second clamping block 19, and the outer wall of the three second clamping blocks 19 is movably inserted into the inside of the three second clamping grooves 18, the outer wall of the three second clamping blocks 19 is provided with a second limiting groove 20, the inner wall of the three second limiting grooves 20 is movably inserted with a wedge-shaped block 21, and the outer wall of the three wedge-shaped blocks 21 is fixedly connected with a reset spring 22.

[0027] The effect achieved by the whole embodiment 2 is that: through the modular design concept, the air-break copper bar contains a protective cover module, the protective cover module is divided into a first protective cover 5 and a second protective cover 6, and after the assembly of the plurality of copper bar modules is completed, the protective cover module can be fixed to one side of the outer wall of the protective shell 1. The protective cover module mainly provides environmental isolation protection, effectively blocks the invasion of harmful substances such as dust and moisture, prevents the copper bar module and the connecting part from being damaged, and can prevent accidental impact on the copper bar system caused by personnel mis-touch or external objects, effectively avoiding the occurrence of electrical faults such as short circuit and open circuit, thereby ensuring the long-term stable operation of the copper bar, and the fixing mode thereof also adopts a double locking mechanism of elastic clamping components and threaded fixing components, ensuring the stability and durability of the protective cover module in long-term use.

[0028] The working principle of the whole device is that: through the modular design concept, the air-break copper bar system is divided into copper bar modules and protective cover modules. In actual application, users can flexibly assemble the copper bar length according to specific installation requirements. When assembling, the operator first accurately embeds the embedding blocks 4 of the two adjacent copper bar bodies 2 into the adjacent embedding grooves 3, at the same time, the two first clamping blocks 8 are accurately clamped into the corresponding first clamping grooves 7. Then, by rotating the knob 16, the knob 16 drives the adjusting screw 15 to rotate, and by the threaded cooperation between the adjusting screw 15 and the threaded groove 14, the rotation of the adjusting screw 15 will push the sliding plate 13 to move downward, thereby making the two first limiting blocks 10 at the bottom of the sliding plate 13 inserted into the corresponding first limiting grooves 9, realizing the preliminary fixation of the two copper bar modules. At the same time, the second clamping block 19 will also be smoothly inserted into the corresponding second clamping groove 18, and during the insertion process, the inclined surface of the second clamping block 19 will be in contact with the inclined surface of the wedge-shaped block 21, causing the wedge-shaped block 21 to be extruded and move towards the inside of the protective shell 1. This movement will further extrude the reset spring 22, and when the second clamping block 19 completely reaches the bottom of the second clamping groove 18, the position of the second limiting groove 20 corresponds to the position of the wedge-shaped block 21. Under the elastic action of the reset spring 22, the wedge-shaped block 21 will pop back and be clamped into the corresponding second limiting groove 20, so that the two copper bar modules are fixed more firmly. In this simple and efficient way, multiple copper bar modules can be quickly spliced to ensure that the length of the copper bar meets the actual requirements. After the copper bar module is assembled, the protective cover module needs to be used to fix the two ends. The protective cover module is divided into a first protective cover 5 and a second protective cover 6. The fixing method of the protective cover module and the copper bar module is the same as the fixing method between the copper bar modules. By following the above operation process, the fixation of the protective cover module can be quickly completed, thereby providing good environmental isolation and electrical safety protection for the long-term use of the air-break copper bar.
