Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a busbar connection device. Background Technology

[0002] Busbar connections are electrical components used for centralized connection and distribution of electrical energy. Their core function is to converge or divide multiple current streams, achieving efficient and safe circuit connections. Essentially, busbar connections act as "intermediate transfer stations" in circuits, primarily addressing the messiness and inefficiency of traditional wire connections. They concentrate the current from multiple independent power sources or branch circuits into one location, such as in a photovoltaic system where the current from multiple solar panels is fed into the inverter. Furthermore, they divide the total current into multiple paths, delivering it to different electrical devices; for example, in a distribution box, the total power supply is divided into different circuits for lighting, sockets, air conditioning, etc. They also replace numerous scattered wires and terminals, reducing connection points, lowering the risk of contact failures, and making the circuit layout clearer and easier for future maintenance.

[0003] Existing busbars use bolts to connect to components such as wires. However, the bolts and the main body of the busbar are connected, carrying high voltage when energized. Exposed live bolts pose a significant safety hazard, especially in areas where personnel may come into contact with them. Furthermore, they are easily affected by accidental impacts, dust accumulation, or moisture corrosion, impacting the reliability of the connection. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a busbar connection device that offers the advantage of easy bolt protection. This solves the problem that existing busbars use bolts to connect to components such as wires, but the bolts and the busbar body are connected, carrying high voltage when energized. Exposed live bolts pose a significant safety hazard, especially in areas where personnel may come into contact with them. Furthermore, they are easily affected by accidental impacts, dust accumulation, or moisture corrosion, impacting the reliability of the connection.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a busbar connection device, comprising a main body assembly, wherein the main body assembly includes: Busbars, with bolts symmetrically arranged on them; The busbar is provided with a protective component, which includes: A shielding frame is slidably connected to the top of the busbar; The connecting rod is fixedly connected to the outer wall of the shielding frame; A limiting block is fixedly connected to the bottom end of the connecting rod, and an inclined surface is provided on the limiting block; A limiting groove is formed on the limiting block; The frame is fixedly connected to the outer wall of the busbar; A cavity is formed within the frame. One end of the spring is fixedly connected to the inner wall of the cavity; A limiting rod is fixedly connected to the other end of the spring; The pull rod has one end fixedly connected to the outer wall of the limiting rod, and the other end extends through and out of the frame.

[0006] Preferably, the protective components, except for the shielding frame, are symmetrically provided in two sets, located on both sides of the busbar.

[0007] Preferably, the inner wall of the cavity is symmetrically provided with sliding grooves, and the two ends of the limiting rod extend and are slidably connected in the sliding grooves.

[0008] Preferably, the busbar, the shielding frame, and the cavity are provided with limiting components, the limiting components including: Spring two is symmetrically and fixedly connected to the inner wall of the cavity; A spring plate is slidably connected within the cavity, and the spring plate is fixedly connected to the second spring. A magnetic plate is fixedly connected to the rear side wall of the shielding frame; A metal sheet is fixedly connected to the top of the busbar, and the magnetic sheet is magnetically attracted to the metal sheet.

[0009] Preferably, a sealing strip is provided at the bottom of the shielding frame.

[0010] Preferably, the outer side wall of the shielding frame is symmetrically and fixedly connected with anti-slip protrusions.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a busbar connection device, which has the following advantages: This connecting device offers the advantage of easy bolt protection. The shielding frame slides directly towards the bolt side, at which point the limiting block at the top of the connecting rod inserts into the cavity. When the inclined surface of the limiting block contacts the limiting rod, it pushes the limiting rod towards the spring. The spring is compressed, and when the limiting groove on the limiting block moves to the limiting rod, the spring ejects the limiting rod outward, and the limiting rod automatically enters the limiting groove, thus connecting the shielding frame to the frame body. At this point, the shielding frame protects and shields the bolt, increasing the safety of the busbar and bolt usage. This solves the problem that existing busbars use bolts to connect to wires and other components, but the bolts and the busbar body are connected, carrying high voltage when energized. Exposed live bolts pose a significant safety hazard, especially in areas where personnel may come into contact with them. Furthermore, they are easily affected by accidental impacts, dust accumulation, or moisture corrosion, affecting the reliability of the connection. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 See Figure 1-5A busbar connection device includes a main component 1, which includes: a busbar 11 with bolts 12 symmetrically arranged thereon; a protective component 2 on the busbar 11, which includes: a shielding frame 21 slidably connected to the top of the busbar 11; a connecting rod 211 fixedly connected to the outer wall of the shielding frame 21; a limiting block 22 fixedly connected to the bottom end of the connecting rod 211, and the limiting block 22 has an inclined surface; a limiting groove 221 formed on the limiting block 22; a frame 23 fixedly connected to the outer wall of the busbar 11; a cavity 24 formed inside the frame 23; a spring 25, one end of which is fixedly connected to the inner wall of the cavity 24; a limiting rod 26 fixedly connected to the other end of the spring 25; and a pull rod 27, one end of which is fixedly connected to the outer wall of the limiting rod 26, and the other end extends through and to the outside of the frame 23. Except for the shielding frame 21, the protective components 2 are symmetrically provided in two sets, respectively located on both sides of the busbar 11. The inner wall of the cavity 24 is symmetrically provided with sliding grooves 4, and the two ends of the limiting rod 26 extend and slide in the sliding grooves 4.

[0016] When it is necessary to cover the exposed bolt 12, the worker simply slides the covering frame 21 toward the bolt 12. At this time, the limiting block 22 at the top of the connecting rod 211 is inserted into the cavity 24. When the inclined surface of the limiting block 22 contacts the limiting rod 26, it pushes the limiting rod 26 toward the spring 25. The spring 25 is compressed. When the limiting groove 221 on the limiting block 22 moves to the limiting rod 26, the spring 25 pops the limiting rod 26 outward. The limiting rod 26 automatically enters the limiting groove 221, thereby connecting the covering frame 21 with the frame 23. At this time, the covering frame 21 protects and covers the bolt 12, thereby increasing the safety of the busbar 11 and the bolt 12. When bolt 12 needs to be exposed for inspection or maintenance, the worker pulls the lever 27 outwards. The lever 27 causes the limiting rod 26 to disengage from the limiting groove 221. At this time, the shielding frame 21 slides out of the area above bolt 12, facilitating inspection or maintenance. Protective components 2 are symmetrically provided on both sides of the busbar 11, ensuring that both sides of the shielding frame 21 have limiting blocks 22 that limit the frame body 23, thereby increasing the stability of the shielding frame 21 during protection. When the limiting rod 26 moves due to the influence of the limiting block 22 and spring 25, both ends of the limiting rod 26 slide within the sliding groove 4. The sliding groove 4 guides the limiting rod 26, thereby increasing the stability of the limiting rod 26 during movement and preventing it from tilting, which would affect the automatic limiting effect on the limiting block 22.

[0017] The core working principle of the aforementioned bus 11 is to concentrate or distribute current through a conductive body, achieving efficient connection of multiple circuits. The usage process revolves around "installation-wiring-inspection-power-on," with the core focus on ensuring connection safety and stable current transmission. When multiple dispersed currents (such as the output current of photovoltaic panels or battery packs) need to be collected, the wires of each branch are connected to the "input terminal" of the bus. The current is concentrated at one point through the low-resistance bus body (copper / aluminum busbar) and then flows from the "total output terminal" to subsequent equipment (such as inverters or main switches). When a single total current needs to be branched, the total current is first connected to the "total input terminal" of the bus, and then distributed through the bus body to multiple "branch output terminals," flowing to different power circuits (such as lighting, sockets, and motors), achieving on-demand distribution. The specific structure of bus 11 will not be described in detail here.

[0018] Example 2 An auxiliary function has been added based on Embodiment 1.

[0019] See Figure 1-5 Limiting components 3 are provided on the busbar 11, the shielding frame 21, and the cavity 24. The limiting components 3 include: a second spring 31, symmetrically and fixedly connected to the inner wall of the cavity 24; a spring plate 32, slidably connected to the cavity 24, and fixedly connected to the second spring 31; a magnetic absorbing sheet 33, fixedly connected to the rear side wall of the shielding frame 21; and a metal sheet 34, fixedly connected to the top of the busbar 11, with the magnetic absorbing sheet 33 and the metal sheet 34 magnetically attracted to each other. A sealing strip 6 is provided at the bottom of the shielding frame 21. Anti-slip protrusions 5 are symmetrically and fixedly connected to the outer side wall of the shielding frame 21.

[0020] When the limiting block 22 is inserted into the cavity 24, it simultaneously pushes the spring plate 32 towards the side of the second spring 31. At this time, the second spring 31 is compressed. When the operator needs to open the shielding frame 21 and pulls the lever 27, the deformed spring 31 pushes the spring plate 32 to move. The spring plate 32 ejects the limiting block 22 outward. The limiting block 22 drives the shielding frame 21 to move through the connecting rod 211 until the magnetic plate 33 and the metal plate 34 are attracted by magnetism. Thus, when the lever 27 is pulled, the shielding frame 21 is automatically limited at the metal plate 34, preventing the shielding frame 21 from shaking randomly during maintenance. When the shielding frame 21 is in protective condition, the sealing strip 6 at the bottom achieves a sealing effect at the shielding frame 21, preventing moisture from entering the vicinity of the bolt 12 through the shielding frame 21, which would affect the service life of the bolt 12 and the manifold 11. The anti-slip protrusions 5 on the outside of the shielding frame 21 increase the friction between the hand and the shielding frame 21 when the staff pushes the shielding frame 21, making the process of pushing the shielding frame 21 smoother and faster.

[0021] 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.
