Description

Technical Field

[0001] This utility model relates to a copper busbar installation structure and busbar trunking. Background Technology

[0002] In modern electrical equipment, busbar trunking is an important component for power transmission, and the stability of its connection with copper busbars directly affects the efficiency and safety of power transmission.

[0003] Traditional copper busbar installation structures mostly connect the fixing plates to the busbar trunking with bolts, which is cumbersome, complex, and time-consuming. Furthermore, the fixing plates are prone to loosening under equipment vibration or thermal expansion and contraction, leading to unstable connections between the copper busbar and the busbar trunking, thus affecting the reliability of power transmission. In addition, traditional structures require high precision in fixing the copper busbars during installation; even slight deviations in the busbar's position make effective fixing and adjustment difficult, limiting its application scenarios and installation efficiency.

[0004] Therefore, a copper busbar installation structure and busbar trunking are proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a copper busbar installation structure and busbar trunking to solve the problem mentioned in the background art that traditional copper busbar installation structures are difficult to fix and adjust effectively.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a copper busbar installation structure, including fixing plates disposed at the upper and lower ends of the power-connecting copper busbar, two sets of fixing plates being connected to the busbar groove through fixing components, a connecting groove being provided in the middle of the fixing plates, and multiple sets of locking structures for fixing the power-connecting copper busbar being disposed in the connecting groove.

[0007] The fixing clamp is connected to the busbar trunking through a fixing component, and the copper busbar is locked and fixed by a locking structure.

[0008] Preferably, the fixing component includes a fixing sleeve disposed around the upper periphery of the fixing clamp, a fixing bolt slidably connected inside the fixing sleeve, and a return spring disposed inside the fixing sleeve on the outer periphery of the fixing bolt, so that the fixing bolt can move elastically on the outer periphery of the fixing bolt by means of the return spring.

[0009] Preferably, the opening side of the fixed sleeve is provided with a guide groove, and the guide groove is rectangular in shape.

[0010] Preferably, the fixing bolt includes a bolt cap, a bolt rod, and a positioning rod arranged sequentially from right to left. The bolt rod is connected to the bolt rod inside the fixing sleeve, and the positioning rod is located in the middle of the return spring. The bolt cap is located outside the fixing sleeve, so that the worker can fix it to the busbar side by connecting the bolt cap to the positioning rod.

[0011] Preferably, a guide slide is provided on one side of the bolt rod, and the guide slide has a notch on the side closer to the bolt cap, so that the guide slide can rotate through the notch on the opening side of the fixed sleeve.

[0012] Preferably, a limiting plate is provided on the side of the bolt rod away from the bolt cap, and the outer diameter of the limiting plate is larger than the opening of the fixed sleeve, so that the bolt rod can move linearly inside the fixed sleeve through the limiting plate.

[0013] Preferably, the locking structure includes a locking clamp disposed on the upper part of the power-connecting copper busbar, the top end of the locking clamp being connected to a bolt via a screw, and the bolt being disposed on the fixing clamp plate through a connecting groove.

[0014] Preferably, guide protrusions are provided on both sides of the fixing plate, and the guide protrusions are rectangular in shape.

[0015] A busbar trunking system is provided for connection with a copper busbar mounting structure. The busbar trunking system includes two sets of side plates. Each side plate has a sliding groove that mates with a guide protrusion. Positioning holes are provided on both sides of the sliding groove, and the positioning holes mate with positioning rods.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model connects the fixing plate to the busbar trunking through a fixed component. Workers can operate the fixing bolt using the bolt cap. With the help of the elastic action of the return spring, the fixing bolt can be more easily connected and fixed to the busbar trunking, eliminating the traditional complicated bolt tightening process, effectively shortening the installation time and improving the installation efficiency.

[0018] Under conditions such as equipment vibration, the traditional fixed clamp and the copper busbar are prone to loosening. This application uses a locking structure to firmly lock the copper busbar into the connecting groove of the fixed clamp. The locking clamp and the fixed clamp are connected by a screw and bolt, and the locking position and tightness can be flexibly adjusted. Multi-directional fixing ensures that the connection between the copper busbar and the busbar trunking remains stable under various working conditions, ensuring the continuity and reliability of power transmission.

[0019] Furthermore, the guide protrusions on both sides of the locking clamp cooperate with the busbar groove. When adjusting the position of the copper busbar, the guide protrusions slide along the groove, achieving precise positioning and installation of the copper busbar, improving installation flexibility and fault tolerance, reducing installation difficulty, and expanding application scenarios.

[0029] Please see Figure 1-7This utility model provides a copper busbar installation structure, including fixing plates 1 disposed at the upper and lower ends of the power-connecting copper busbar. Two sets of fixing plates 1 are connected to a busbar trough via fixing components 2. The fixing components 2 include fixing sleeves 21 disposed around the upper periphery of the fixing plates 1. A fixing bolt 22 is slidably connected inside the fixing sleeves 21. A return spring 23 is disposed inside the fixing sleeves 21 on the outer periphery of the fixing bolt 22, allowing the fixing bolt 22 to move elastically on its outer periphery via the return spring 23. A guide groove 24 is provided on the open side of the fixing sleeves 21, and the guide groove 24 is rectangular in shape. The fixing bolt 22 includes a bolt cap 221, a bolt rod 222, and a positioning rod 223 arranged sequentially from right to left. The bolt rod 222 is located inside the fixing sleeve 21, and the positioning rod 223 is located in the middle of the return spring 23. The bolt cap 221 is located outside the fixing sleeve 21, allowing the operator to fix the bolt to the busbar trough side via the bolt cap 221 and the positioning rod 223. A guide slide rod 2221 is provided on one side of the bolt rod 222, and a notch 2222 is provided on the side of the guide slide rod 2221 closer to the bolt cap 221, allowing the guide slide rod 2221 to rotate through the notch 2222 on the open side of the fixing sleeve 21. A limiting plate 2223 is provided on the side of the bolt rod 222 away from the bolt cap 221. The outer diameter of the limiting plate 2223 is larger than the opening of the fixing sleeve 21, allowing the bolt rod 222 to move linearly inside the fixing sleeve 21 via the limiting plate 2223.

[0030] A connecting groove 11 is provided in the middle of the fixed clamping plate 1, and multiple sets of locking structures 3 for fixing the copper busbar are provided in the connecting groove 11. The locking structure 3 includes a locking clip 31 provided on the upper part of the copper busbar. The top end of the locking clip 31 is connected to a bolt 33 through a screw 32, and the bolt 33 is provided on the fixed clamping plate 1 through the connecting groove 11.

[0031] The fixing clamp 1 is connected to the busbar trunking through the fixing component 2, and the copper busbar is locked and fixed by the locking structure 3.

[0032] Guide protrusions 12 are provided on both sides of the fixed clamping plate 1, and the guide protrusions 12 are rectangular in shape.

[0033] A busbar trunking system is provided for connection with a copper busbar mounting structure. It includes two sets of side plates 4. Each set of side plates 4 has a sliding groove 41 on both sides that mates with a guide protrusion 12. Positioning holes 42 are provided on both sides of the sliding groove 41, and the positioning holes 42 mate with positioning rods 223.

[0034] The working principle of the copper busbar installation structure and busbar trunking provided by this utility model is as follows: The fixing clamp 1 is inserted into the sliding groove 41 of the side plate 4 through the guide protrusions 12 on both sides until the fixing sleeve 21 of the fixing clamp 1 is aligned with the positioning hole 42. At this time, press the bolt cap 221 so that it moves along the guide groove 24 of the fixing sleeve 21 to the side plate 4 through the guide slide 2221 of the bolt rod 222, and squeeze the return spring 23. The return spring 23 is compressed and deformed until the positioning rod 223 is fully inserted into the positioning hole 42.

[0035] At this time, the notch 2222 of the guide slide rod 2221 is flush with the opening of the fixed sleeve 21. Rotate the cap 221 so that the guide slide rod 2221 is engaged inside the fixed sleeve 21, fixing the position of the positioning rod 223, thereby realizing the initial connection between the fixed clamp plate 1 and the busbar groove.

[0036] The conductive copper busbar is clamped by two sets of fixing plates 1. Then, using a wrench or other tools, the bolt 33 is rotated to gradually move the locking clamp 31 towards the fixing plates 1, thereby tightly clamping the copper busbar between the locking clamp 31 and the fixing plates 1. During the tightening process, carefully observe the force on the copper busbar to ensure that the force is even and to avoid damaging the copper busbar due to excessive tightening force.

[0037] Repeat the above steps to lock and fix the other copper busbars in the connecting groove 11, ensuring that all copper busbars are firmly fixed on the fixing plate 1.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
