Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a copper busbar wiring terminal for an electrical cabinet. Background Art

[0002] In the wiring arrangement of an electrical cabinet, it is often necessary to use copper busbars and terminal blocks to cooperate with each other to divide the electrical cabinet wires. Due to the strong conductivity of the copper busbar, it can be connected to external wires through the copper busbar to introduce external power into the electrical cabinet. Then, one or more terminal blocks are set on the copper busbar to facilitate connection with each branch wire, thereby realizing current diversion in the electrical cabinet.

[0003] In the existing technology, it is often necessary to first connect the terminal blocks to the copper busbar by locking them in sequence, and then pass each branch wire through the preset connection hole on the terminal block to wrap and fix it to the terminal block, thereby achieving electrical connection with the winding terminal. This is more troublesome to operate, and it is impossible to increase or decrease the number of connecting terminals during use. In addition, the risk factor of connecting or removing branch wires in a live state is relatively high, so improvement is needed. Utility Model Content

[0023] like Figures 1 to 4 As shown, a copper busbar terminal for an electrical cabinet includes a terminal body 10. The terminal body 10 is provided with a copper busbar quick-connect slot 11 and a wire quick-connect hole 12. The copper busbar quick-connect slot 11 and the wire quick-connect hole 12 are respectively arranged on different sides of the terminal body 10. A conductive copper block 13 is provided on the terminal body 10. The conductive copper block 13 connects the copper busbar quick-connect slot 11 and the wire quick-connect hole 12 to achieve electrical connection between the copper busbar quick-connect slot 11 and the wire quick-connect hole 12. When installing the terminal block, first use the copper busbar quick-connect slot 11 provided on the terminal body 10 to stably connect with the external copper busbar, and then connect with the external branch wire through the wire quick-connect hole 12. The copper busbar and the branch wire are in contact with the conductive copper block 13 provided at the terminal block, thereby facilitating the electrical connection between the copper busbar and the branch wire through the conductive copper block 13, thereby realizing the rapid installation or removal of the terminal block. In addition, when dealing with copper busbars of different specifications, a terminal block with a copper busbar quick-connect slot 11 of the corresponding specification to the copper busbar can be used to adapt to copper busbars of different specifications.

[0024] The terminal body 10 includes a terminal base 19, which is provided with an installation space. A side of the terminal base 19 is provided with an installation opening connected to the installation space. A base cover 20 is provided on one side of the terminal base 19 to cover the installation opening. The copper busbar quick-connect slot 11 and the wire quick-connect hole 12 are provided on opposite sides of the terminal base 19. In this embodiment, by providing an installation space within the terminal base 19, the conductive parts within the terminal body 10 can be installed through the installation space. At the same time, a base cover 20 is provided at the installation opening to facilitate covering the installation opening, thereby improving the structural stability of the terminal after assembly.

[0025] A copper block slot is provided in the installation space, and the conductive copper block 13 is fixed in the copper block slot. In this embodiment, a copper block slot is provided in the installation space, and the conductive copper block 13 is in the shape of a number seven. The conductive copper block 13 is fixed in the copper block slot and is connected to the copper busbar quick-connect notch 11 and the wire quick-connect hole 12 through the copper block slot.

[0026] A first spring clip slot is provided in the installation space, in which a copper bar spring clip 14 is clamped. The copper bar spring clip 14 extends outward to one side of the copper bar quick-connect slot 11. The copper bar spring clip 14 cooperates with the copper bar quick-connect slot 11 to achieve clamping connection with the external copper bar. In this embodiment, a first spring clip slot is provided in the installation space. By disposing the copper bar spring clip 14 in the first spring clip slot and extending the copper bar spring clip 14 into the copper bar quick-connect slot 11, when the copper bar is clamped into the copper bar wiring slot, the copper bar spring clip 14 clamps the copper bar in place, allowing the copper bar to be stably clamped into the copper bar quick-connect slot 11, thereby achieving a stable connection between the wiring terminal and the copper bar.

[0027] The terminal body 10 is provided with a first control portion 17 corresponding to the copper bar spring piece 14. The first control portion 17 is in transmission connection with the copper bar spring piece 14 and controls the extension or retraction of the copper bar spring piece 14. In this embodiment, by providing the first control portion 17 on the terminal body 10, the extension and retraction of the copper bar spring piece 14 can be controlled by pressing or releasing the first control portion 17. When the first control portion 17 is pressed, the copper bar spring piece 14 contracts inward, which facilitates the separation of the copper bar from the copper bar quick-connect slot 11. By releasing the first control portion 17, the copper bar spring piece 14 is reset and extended into the copper bar quick-connect slot 11, thereby facilitating the engagement of the copper bar.

[0028] A second spring clip slot is provided within the installation space, and a wire spring clip 15 is secured within the second spring clip slot. The wire spring clip 15 is located above the wire quick-connect hole 12 and extends toward the conductive copper block 13, bringing the external wire into contact with the conductive copper block 13. In this embodiment, the second spring clip slot is provided within the installation space to facilitate installation of the wire spring clip 15. The wire spring clip 15 facilitates securing the branch wire extending into the wire quick-connect hole 12, thereby achieving electrical connection between the branch wire and the conductive copper block 13.

[0029] The terminal body 10 is provided with a second control portion 18 corresponding to the wire spring 15. The second control portion 18 is in transmission connection with the wire spring 15. The second control portion 18 controls the relative position of the wire spring 15 and the conductive copper block 13. In this embodiment, the second control portion 18 is provided at the terminal body 10. By pressing or releasing the second control portion 18, the wire spring 15 can be easily controlled to be positioned. When the second control portion 18 is pressed, the wire spring 15 is lifted by force. At this time, the wire spring 15 is away from the conductive copper block 13, thereby facilitating the branch wire to enter or move out of the wire quick-connect hole 12. When the second control portion 18 is released, the wire spring 15 is reset to be close to the conductive copper block 13, thereby facilitating the clamping of the branch wire in the wire quick-connect hole 12, thereby achieving stability in the connection between the branch wire and the terminal.

[0030] A third spring clip slot is provided in the installation space, and a limiting spring clip 16 is provided in the third spring clip slot. One end of the limiting spring clip 16 abuts against the conductive copper block 13 to limit the conductive copper block 13. In this embodiment, the third spring clip slot is provided in the installation space. By providing the limiting spring clip 16 in the third spring clip slot, the conductive copper block 13 can be easily limited by the limiting spring clip 16. When the copper busbar is connected to the copper busbar quick-connect slot 11, friction with the conductive copper block 13 causes the conductive copper block 13 to move inward. At this time, the conductive copper block 13 exerts a certain amount of pressure on the limiting spring clip 16. When the copper busbar moves out of the copper busbar quick-connect slot 11, the limiting spring clip 16 will exert a certain reaction force on the conductive copper block 13, causing the conductive copper block 13 to reset, thereby facilitating the next clamping connection between the terminal block and the copper busbar.

[0031] The terminal body 10 further includes a conductive galvanized plate 30, which is disposed between the terminal base 19 and the base cover 20. In this embodiment, the conductive galvanized plate 30 is provided to further improve the stability of the terminal.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
