Description

Technical Field

[0001] This utility model belongs to the field of solid busbar technology and relates to a novel high-current busbar device. Background Technology

[0002] In electrical systems, high-current busbars are key components for current transmission and distribution, and their safety protection and convenient maintenance are crucial for the stable operation of the system.

[0003] Traditional busbars, with their exposed copper busbars lacking protection, are prone to short circuits, leakage, and other safety hazards, threatening electrical systems and personnel safety. Rubber sleeves are used to protect the screw parts, but these sleeves are prone to aging and failure, and their protective performance deteriorates after long-term use, also posing safety risks.

[0004] Existing busbar protection devices use a protective shell around the busbar. This shell requires screw holes to be drilled at the installation location, and the entire shell is fixed to the installation location by screwing in the screws through the through holes. This increases assembly steps and maintenance costs. Frequent disassembly and reassembly can also damage the installation structure. In emergency situations such as replacing wires, existing protection devices require loosening the screws and removing the protective shell, which is cumbersome and time-consuming, seriously affecting the efficiency of fault handling.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] To achieve the above objectives, this utility model provides a novel high-current busbar device, as shown in the reference. Figures 1 to 6As shown, the device includes a base 1, a protective shell 2, and a solid busbar 3. The solid busbar 3 is fastened to the base 1. The base 1 has integrated positioning strips 4 on both sides of the solid busbar 3 to facilitate quick positioning during installation. The base 1 has a removable protective shell 2 to cover and protect the solid busbar 3, reducing the impact of rain and dust from the external environment and protecting the solid busbar 3 during use. The upper surface of the base 1 has guide recesses 5 around its perimeter. The bottom of the left and right sides of the protective shell 2 has protruding inserts 6, which can be C-shaped. The protruding inserts 6 are fitted into the guide recesses 5 to allow the protective shell 2 to be quickly aligned with the base 1. The lower left and right sides of the base 1 have grooves 7. The middle of the left and right outer sides of the protective shell 2 has downward-facing extension arms 8. The inner side of the extension arms 8 has fasteners 9, which are fastened into the grooves 7 to allow the protective shell 2 to be detachably connected to the base 1.

[0026] Furthermore, the solid busbar 3 is provided with several first threaded blind holes 10, second threaded blind holes 11, and through third threaded holes 12 through the CNC machining process. The first threaded blind holes 10 are located at the bottom of the solid busbar 3, the second threaded blind holes 11 are located on the left and right sides of the solid busbar 3, and the third threaded holes 12 are located through the top and bottom of the solid busbar 3. The bottom of the solid busbar 3 is provided with recessed holes 13 at the positions of the third threaded holes 12. The base 1 is provided with several first screw holes 21, which are correspondingly fastened to the first threaded blind holes 10. The second threaded blind holes 11 are used to connect the metal terminals of the external small current electrodes, which are fastened to the second threaded blind holes 11 by screws. The third threaded holes 12 are used to connect the pure copper connection terminals of the external large current electrodes, which are fastened to the third threaded holes 12 by screws.

[0027] Furthermore, each solid busbar 3 has a screw post 14 located in the third threaded hole 12. The screw post 14 is tightly fitted into the third threaded hole 12, with its upper part exposed on the upper surface of the solid busbar 3. A removable nut 15 is provided on the screw post 14. For tightening, the pure copper connecting terminal is inserted into the screw post 14, and then the nut 15 is screwed into the screw post 14 to secure the pure copper connecting terminal to the solid busbar 3. For disassembly, the nut 15 is loosened, and the pure copper connecting terminal is removed and replaced.

[0028] Furthermore, the protective shell 2 is made of transparent plastic material, which makes it easy to observe the internal situation. The top surface of the protective shell 2 is integrally connected with several concave surfaces 17, and transparent labels 18 are affixed to the concave surfaces 17. The transparent labels 18 can be used to distinguish the use of the corresponding pure copper connection terminals. The internal connection of the solid busbar 3 can be observed, eliminating the need to disassemble the protective shell 2 every time, thus reducing the number of disassemblies and extending the service life. The front and rear ends of the protective shell 2 are provided with several avoidance arches 16 to facilitate the avoidance of the connection lines of the pure copper connection terminals.

[0029] Furthermore, the protective shell 2 is integrally formed with horizontally and vertically interlocking sheet-like reinforcing ribs 19. The protective shell 2 is made of plastic and has a certain degree of elasticity. When the buckle 9 is inserted into the groove 7, the extension arm 8 will be slightly forcefully extended outward to make the buckle 9 and the groove 7 fasten and connect. When the protective shell 2 is removed, because the protective shell 2 is long and narrow, there will be a certain gap between the protective shell 2 and the two sides of the base 1. With a little force, the two concave ends of the protective shell 2 tend to lift up, and the buckle 9 can be separated from the groove 7. The disassembly and assembly are very convenient.

[0030] Furthermore, the base 1 has several countersunk screw holes 20 around its perimeter for mounting and fixing, which facilitates fixing the base 1. The protective shell 2 only needs to be fastened to the base 1, eliminating the need for multiple screw holes on the protective shell 2 for fixing it in the traditional way, thus reducing production and installation costs.

[0031] In summary, this utility model provides a novel high-current busbar device. The protective shell 2, which is detachably installed on the base 1 with a guide alignment and fastening connection, protects the solid busbar 3 and offers the advantages of convenient disassembly and assembly, reliable protection, no drilling required, simplified assembly, and lower cost.

[0032] The technical principles of this utility model have been described above with reference to specific embodiments, which are merely preferred embodiments of this utility model.
