DETAILED DESCRIPTION

[0026] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] Reference example Figures 1 to 6 A busbar support with a protective function comprises a base 1 and a cover plate 2 fixed on the base 1. The base 1 is provided with a plurality of brackets 3 from top to bottom, and the brackets 3 are mutually staggered. The brackets 3 are provided with a retractable clamping plate 4, and the clamping plate 4 is provided with a busbar 5. A copper bar 6 is provided in the base 1 and passes through the clamping plate 4. The clamping plate 4 is provided with a fastener 7. The fastener 7 is rotated to shrink the clamping plate 4 so that the busbar 5 abuts against the copper bar 6. When the fastener 7 is rotated, the thread of the fastener 7 is engaged with the thread of the clamping plate 4. As the fastener 7 rotates, the pitch of the thread is the linear distance moved each time the fastener 7 rotates, and the rotary motion is converted into a linear motion, so that the distance between the clamping plate 4 and the copper bar 6 gradually increases, and the distance between the barb 42 and the copper bar 6 gradually shortens, thereby achieving the function of fixing the busbar 5;

[0029] It is worth mentioning that guide plates 31 are provided on both sides of the bracket 3, and guide grooves 32 are provided on the guide plates 31. Partition plates 33 are provided on both sides of the bracket 3. The partition plates are arranged on both sides of the base 1. The guide plates 31 provide a guide for the supporting plate 41. The guide grooves 32 prevent the clamping plate 4 from fixing the busbar 5. After the busbar 5 is fixed, the busbar 5 is affected by the gravity of one end, causing one side of the supporting plate 41 to tilt up, thereby reducing the contact area with the copper busbar 6 and ensuring that the supporting plate 41 is stably connected to the guide plate 31. The partition plates 33 not only block the air gap between the busbars 5 and improve the insulation, but also support the slight bending of the busbar 5 caused by its excessive length.

[0030] It is worth mentioning that the two sides of the clamping plate 4 are provided with supporting plates 41, which abut against the guide plate 31, the supporting plate 41 is provided with barbs 42, which abut against the busbar 5, and the outer wall of the supporting plate 41 is provided with guide blocks 43, which are inserted into the guide groove 32, the supporting plate 41 provides support for the busbar 5, the barbs 42 provide support points for the busbar 5, and the guide blocks 43 are used in conjunction with the guide groove 32;

[0031] It is worth mentioning that a concave cavity 11 corresponding to the bracket 3 is provided in the base 1, and a plurality of equally spaced wire grooves 12 are provided at the bottom of the concave cavity 11. The concave cavity 11 is provided with a clearance through hole 13. The concave cavity 11 provides a storage space for the copper bus 6 to be connected with the wire. The wire groove 12 facilitates the wire to be inserted into the concave cavity 11. Each wire groove 12 corresponds to a wire, which is convenient for maintenance. The clearance through hole 13 is the intersection of the copper bus 6 and the busbar 5;

[0032] It is worth mentioning that there are avoidance through holes 14 between the concave cavities 11, and a plurality of fixing columns 15 are arranged from top to bottom on the avoidance through holes 13. The avoidance through holes 14 provide accommodation space for the grounding bar 8, and the fixing columns 15 are used in conjunction with the copper bar 6;

[0033] It is worth mentioning that the avoidance through hole 14 is provided with a ground wire row 8, which is connected to the ground wire, which can effectively eliminate static electricity and electromagnetic interference in the electrical equipment, and prevent damage to the electrical equipment or personnel due to unexpected failures. The ground wire row 8 connects all the ground wires in the circuit system together to form a stable grounding system, so that the grounding potential of the entire circuit system remains consistent, which effectively improves the safety of the electrical equipment;

[0034] It is worth mentioning that the cover plate 2 is provided with a plurality of heat dissipation holes 21 from top to bottom, and is located at the entrance of the concave cavity 11 and the avoidance through hole 14. When the busbar 5 transmits current to the copper busbar 6, heat is generated, and the concave cavity 11 and the avoidance through hole 14 exchange heat with the cold air outside through the heat dissipation holes 21;

[0035] It is worth mentioning that the copper busbar 6 is arranged between the supporting plates 41 and arranged in the clearance through hole 13. The copper busbar 6 is provided with a bent extension portion 61 and abuts against the end surface of the fixing column 15. The bent extension portion 61 is provided with a fastening screw 62 to fix the bent extension portion 61 to the fixing column 15. The bent extension portion 61 shortens the distance between the bent extension portion 61 and the heat dissipation hole 21, thereby quickly dissipating heat through the heat dissipation hole 21. The fastening screw 62 fixes the bent extension portion 61.

[0036] It is worth mentioning that the fastener 7 is configured as a screw.

[0037] The above design scheme can enable the product to achieve the advantages of having a protective function, stable support, and quick assembly and disassembly.

[0038] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
