Description

Technical Field

[0001] This utility model relates to the field of copper busbar technology, specifically to a junction box type copper busbar for a distribution box. Background Technology

[0002] Copper busbars, also known as copper busbars, are long conductors made of copper with a rectangular or chamfered rectangular cross-section. They are used in circuits to transmit current and connect electrical equipment. Copper has the second highest electrical conductivity among common metals after silver, enabling it to conduct current efficiently, reduce energy loss during transmission, and improve the efficiency of electrical systems.

[0003] Some copper busbar products adopt a box-type structure, such as the copper busbar structure inside a high-voltage distribution box. Heat dissipation strips may be set on one or both sides of the copper busbar body. The heat dissipation strips are integrally formed with the copper busbar body and are obtained by cutting and folding the side of the copper busbar body. The ends are free ends distributed outside the copper busbar body. Without increasing the cross-sectional area of ​​the copper busbar, the heat dissipation area is increased, which is conducive to the rapid heat dissipation and improves the heat dissipation efficiency of the copper busbar. However, box-type copper busbars often lack quick installation and disassembly devices, which affects the installation efficiency of workers.

[0004] In view of this, we propose a copper busbar with a terminal block for a distribution box. Utility Model Content

[0005] The purpose of this utility model is to provide a copper busbar for the terminal block of a distribution box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A terminal block type copper busbar for a distribution box includes a fixing plate. A fixing screw is threadedly connected to the upper top surface of the fixing plate. A threaded seat is fixedly connected to the bottom of the fixing plate's top center. The bottom of the copper busbar body is fixedly mounted on the top of the threaded seat. A connecting assembly is provided on the fixing plate, the connecting assembly including:

[0008] A rectangular plate, wherein the bottom of the rectangular plate is fixedly installed on the top surface of the fixed plate, a round block is fixedly installed on the top of the rectangular plate, and the top of the connecting plate is fixedly installed on the bottom of the copper busbar body;

[0009] A rotating rod is rotatably mounted inside the connecting plate via bearing components. A first locking block is rotatably mounted outside the rotating rod, and a second locking block is rotatably mounted outside the rotating rod.

[0010] The first and second locking blocks are both fixedly mounted with baffles on their side walls. One end of a spring is fixedly mounted on the bottom of the connecting plate, and the other end of the spring is fixedly connected to the baffle.

[0011] In a further embodiment, multiple sets of fixing screws are provided, and these multiple sets of fixing screws are threadedly connected to the four corners of the fixing plate, thereby better fixing the copper busbar body.

[0012] In a further embodiment, the arc-shaped outer wall of the circular block is fitted between the arc-shaped inner walls of the first and second locking blocks.

[0013] In a further embodiment, the connecting assembly is provided in two sets, with each set of the connecting assembly including two sets of baffles and springs.

[0014] In a further embodiment, the tops of the first and second card blocks are located inside the connecting plate.

[0015] In a further embodiment, the fixing plate is provided with an auxiliary component, which includes a protective shell. The protective shell is fixedly installed on the side wall of the copper busbar body. The protective shell has a connector inside, and the connector has an interface inside. The threaded seat has a threaded post inside, and the threaded post penetrates the copper busbar body.

[0016] In a further embodiment, the protective shell, terminals, and interfaces are provided in multiple sets to better meet various wiring requirements.

[0017] Compared with the prior art, this utility model provides a box-type copper busbar for the wiring terminal of a distribution box, which has the following advantages:

[0018] 1. The terminal box-type copper busbar of this distribution box is equipped with a connecting component to make the copper busbar body easier to install and disassemble.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0029] Please see Figures 1-3 This utility model provides a technical solution:

[0030] A junction box type copper busbar for a distribution box includes a fixing plate 1, a fixing screw 2 threadedly connected to the top upper surface of the fixing plate 1, a threaded seat 3 fixedly connected to the bottom of the top center of the fixing plate 1, and a copper busbar body 4 fixedly mounted on the bottom of the threaded seat 3.

[0031] In one embodiment of this utility model, a connecting component 5 is provided on the fixing plate 1. The connecting component 5 includes a rectangular plate 51. The bottom of the rectangular plate 51 is fixedly installed on the top surface of the fixing plate 1. A round block 52 is fixedly installed on the top of the rectangular plate 51. The top of the connecting plate 53 is fixedly installed on the bottom of the copper busbar body 4. A rotating rod 54 is rotatably installed inside the connecting plate 53 through a bearing component. A first locking block 55 is rotatably installed on the outside of the rotating rod 54. A second locking block 56 is rotatably installed on the outside of the rotating rod 54. Baffles 57 are fixedly installed on the side walls of the first locking block 55 and the second locking block 56. One end of a spring 58 is fixedly installed on the bottom of the connecting plate 53. The other end of the spring 58 is fixedly connected to the baffle 57. Multiple sets of fixing screws 2 are provided, and the multiple sets of fixing screws 2 are threadedly connected to the four corners of the fixing plate 1. The arc-shaped outer wall of the round block 52 fits between the arc-shaped inner walls of the first locking block 55 and the second locking block 56. Two sets of connecting components 5 are provided. Each set of connecting components 5 includes two sets of baffles 57 and springs 58.

[0032] In this embodiment, before installing the copper busbar body 4, the fixing plate 1 is fixed in the corresponding position by multiple sets of fixing screws 2. When the operator installs the copper busbar body 4, they hold the copper busbar body 4 and move the connecting plate 53 downwards, so that the connecting plate 53 gradually approaches the circular block 52 on the rectangular plate 51. The first locking block 55 and the second locking block 56 move downwards together with the connecting plate 53. When the first locking block 55 and the second locking block 56 contact the arc-shaped outer wall of the circular block 52, due to the shape of the circular block 52, an outward squeezing force is generated on the first locking block 55 and the second locking block 56. The squeezing force causes the first locking block 55 and the second locking block 56 to start rotating around the rotating rod 54 to both sides. During the rotation, the baffle 57 also moves along with the first locking block 55 and the second locking block 56. As block 56 moves together, spring 58 is compressed and contracted by first locking block 55 and second locking block 56, generating elastic potential energy. Due to the compression of spring 58, the gap between first locking block 55 and second locking block 56 gradually increases. When round block 52 is completely inserted between first locking block 55 and second locking block 56, first locking block 55 and second locking block 56 are no longer under force. Spring 58 releases elastic potential energy, causing first locking block 55 and second locking block 56 to reset, thus forming a connection between rectangular plate 51 and connecting plate 53, which plays a role in fixing plate 1 and copper busbar body 4. When disassembly is required, disassembly can be completed by reversing the above operation. This installation and disassembly method saves workers' time, thereby improving the efficiency of copper busbar installation, saving time and effort.

[0033] In one embodiment of this utility model, an auxiliary component 6 is provided on the fixing plate 1. The auxiliary component 6 includes a protective shell 61, which is fixedly installed on the side wall of the copper busbar body 4. A connector 62 is provided inside the protective shell 61, and an interface 63 is opened inside the connector 62. A threaded post 64 is threadedly connected inside the threaded seat 3, and the threaded post 64 penetrates the copper busbar body 4. Multiple sets of protective shell 61, connector 62 and interface 63 are provided.

[0034] In this embodiment, after connecting the copper busbar body 4 to the fixing plate 1 using the connecting component 5, although this connection method is relatively convenient for installation and disassembly, it may not be secure enough in some scenarios with high stability requirements. Further fixation of the copper busbar body 4 is needed, using the threaded post 64 for secondary fixation. The operator aligns the threaded post 64 with the threaded seat 3 and then begins to rotate the threaded post 64. As the threaded post 64 rotates, it gradually screws into the threaded seat 3. The protective shell 61 protects the terminal 62 and the interface 63. The operator inserts the wire into the interface 63 of the terminal 62 to achieve electrical connection. Multiple sets of protective shells 61, terminals 62, and interfaces 63 can simultaneously connect multiple wires, meeting the multiple wiring requirements of the copper busbar body 4 in complex circuits. This avoids frequent changes or adjustments to the connection method due to complex wiring requirements, greatly improving work efficiency and making the entire installation and wiring process more efficient and convenient.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
