Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment manufacturing, and more specifically, to a busbar connection structure. Background Art

[0002] The busbar refers to the copper or aluminum busbar that connects the main switch in the electrical cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to be used as a conductor. The main function is to effectively conduct electricity from a power source (such as a transformer or generator) to various power loads. It is not only an important connection point for electrical equipment such as circuit breakers, fuses, switches, etc., but also can be directly installed or connected to these components by bolts, clips or other means. The busbar provides a low-resistance channel for electric current, thereby reducing power loss and ensuring efficient power transmission. In some scenarios, the busbar is also responsible for establishing a stable electrical connection between different components to regulate the voltage within the system.

[0003] At present, in the manufacturing of power equipment, busbars are generally fixed by adhesive and positioning molds. However, this fixing method has many disadvantages, such as high cost, complicated process, manual glue application, long glue solidification time, and degradation of adhesive performance after long-term use. These problems not only increase production costs, but also affect production efficiency, and also reduce the service life of busbar connectors. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a busbar connection structure which has a novel structure and unique functions and is capable of fixing the busbar.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A busbar connection structure includes a plurality of busbars and a plurality of plates disposed on both sides of the busbars. The busbars and the plates are provided with mounting holes. The mounting holes are provided with positive rivets and reverse rivets that are engaged with each other. The busbars are disposed between the positive rivets and the reverse rivets.

[0007] The positive buckle rivet comprises a rivet head and two fan-shaped connecting columns fixedly connected to the rivet head. The side walls of the fan-shaped connecting columns are provided with nylon inner teeth.

[0008] The reverse lock rivet comprises a rivet head 2 and two fan-shaped docking posts fixedly connected to the rivet head 2. The side wall of the fan-shaped docking post is provided with nylon inner teeth 2. The nylon inner teeth 1 and the nylon inner teeth 2 are in opposite directions and are locked with each other.

[0009] The utility model is further configured as follows: an epoxy pad 1 is arranged between the positive buckle rivet and the reverse buckle rivet and the plate body, and an epoxy pad 2 is arranged between the busbar and the plate body.

[0010] The utility model is further configured as follows: the positive buckle rivets and the reverse buckle rivets are both made of high-strength, heat-resistant and insulating nylon material.

[0011] The utility model is further configured as follows: a boss is provided between the two fan-shaped connecting columns, and a docking platform is provided between the two fan-shaped docking columns.

[0012] The utility model is further configured as follows: the plate body is made of polyethylene terephthalate material.

[0013] Compared with the shortcomings of the prior art, the beneficial effects of the utility model are:

[0014] The busbar is fixed with rivets. Nylon internal inverted tooth positive and negative buckle rivets do not need to wait for curing time and can be used immediately after installation, which greatly improves production efficiency. Nylon material has excellent anti-aging properties and resistance to environmental changes, which extends the service life of the busbar connector. By abandoning glue and positioning molds, production costs are reduced, production processes are simplified, and production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, 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 should not be understood as a limitation on the present invention.

[0021] like Figures 1 to 3 As shown,

[0022] The busbar connection structure includes a plurality of busbars 1 and a plurality of plates 2 placed on both sides of the busbar 1. The plates 2 are made of polyethylene terephthalate. The operating temperature of polyethylene terephthalate can reach 120°C, and it has excellent electrical insulation. Even under high temperature and high frequency, its electrical properties are still good, but its corona resistance is poor, and its creep resistance, fatigue resistance, friction resistance and dimensional stability are all very good.

[0023] The busbar 1 and the plate body 2 are provided with mounting holes 3, and mutually buckled positive rivets 4 and reverse buckle rivets 5 are provided in the mounting holes 3. The busbar 1 is placed between the positive buckle rivets 4 and the reverse buckle rivets 5. The positive buckle rivets 4 and the reverse buckle rivets 5 are both made of high-strength, heat-resistant and insulating nylon material, which increases the service life of the positive buckle rivets 4 and the reverse buckle rivets 5.

[0024] The positive buckle rivet 4 includes a rivet head 6 and two fan-shaped connecting columns 7 fixedly connected to the rivet head 6, and a boss is provided between the two fan-shaped connecting columns 7.

[0025] The side wall of the fan-shaped connecting column 7 is provided with a nylon inner tooth 8, an epoxy pad 12 is provided between the positive rivet 4 and the reverse rivet 5 and the plate body 2, and an epoxy pad 13 is provided between the busbar 1 and the plate body 2, which is used to prevent the surface of the busbar 1 from being worn and maintain the seal between the positive rivet 4 and the reverse rivet 5 and the busbar 1 within a predetermined service life.

[0026] The reverse-lock rivet 5 includes a rivet head 9 and two fan-shaped docking columns 10 fixedly connected to the rivet head 9. A docking platform is provided between the two fan-shaped docking columns 10, and the docking platform is in contact with the boss. The side wall of the fan-shaped docking column 10 is provided with nylon internal teeth 11. The nylon internal teeth 8 are in opposite directions to the nylon internal teeth 11 and are interlocked with each other, thereby fixing the busbar 1 between the positive-lock rivet 4 and the reverse-lock rivet 5.

[0027] Working principle: When in use, positive buckle rivets 4 and reverse buckle rivets 5 of different specifications can be designed according to the size and number of layers of the busbar 1. When installing, just press the positive buckle rivet 4 and reverse buckle rivet 5 into the installation hole 3 of the busbar 1, and apply force downward to make the nylon inner tooth 1 8 and the nylon inner tooth 2 11 buckle, and the fixation is completed.

[0028] Since the nylon inner teeth 1 8 and the nylon inner teeth 2 11 are in opposite directions, they will not fall off due to gravity, and the entire installation process is simple and quick without complicated positioning and gluing steps.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
