Description

Technical Field

[0001] This utility model relates to the technical field of terminal blocks, and in particular to a copper busbar structure for terminal blocks. Background Technology

[0002] Terminal blocks (also known as busbars or busbars) are copper conductive strips installed in distribution boxes, terminal boxes, or control cabinets to collect and distribute large currents, replacing traditional distributed wiring and improving safety and maintenance efficiency. Existing terminal blocks are mostly multi-hole type, such as 5-hole, 7-hole, and 10-hole blocks. While these are easy to manufacture, the number of holes required in use is often unsuitable, especially when a large number of holes are needed. In such cases, custom-made busbars or multiple busbars connected in series may be required, which can cause installation inconvenience.

[0003] Chinese Patent Publication No. CN203386922U, published on January 8, 2014, discloses a copper busbar for a terminal block, including a connector and screws. The connector has several wiring holes on its side and a threaded hole communicating with the wiring holes on its upper side. The key feature is that a positioning hole is provided in the center of the connector, and the orientation of the positioning hole is the same as that of the threaded hole. The drawback of this invention is that the number of wiring holes in the terminal block is fixed, which can easily lead to a mismatch in quantity during actual use. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing terminal busbars with a fixed number of wiring holes that are unsuitable for actual needs, and provides a terminal busbar structure that can increase the number of wiring holes according to actual needs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A copper busbar structure for wiring terminals, comprising: A single-ended end, wherein several single-ended ends are provided and evenly distributed; A connector rod is mounted on a single end, and the single end is connected to an adjacent single end via the connector rod. A limiting frame, wherein the limiting frame is installed on the bottom surface of the single end; A fixing plate is installed at one end of a plurality of single-end heads.

[0006] A single wire can be fixed to one end. Two adjacent single ends can be connected and attached together through the plug rod on the single end. The number of single ends can be increased or decreased according to the actual needs of the use. Then, the two adjacent single ends are limited and fixed by the limiting frame to ensure that the single ends are connected as a whole. Finally, the single ends are fixed by installing a fixing plate on one side of the single ends for installing the copper busbar composed of single ends. This achieves the purpose of increasing the number of wiring holes according to actual needs.

[0007] Preferably, the single-ended connector has a wiring hole at its front end and a fixing rod at its upper end. The lower end of the fixing rod passes through the single-ended connector and is placed inside the wiring hole. A screwing block is installed at the upper end of the fixing rod, and the fixing rod is threadedly connected to the single-ended connector. The wiring hole of the single-ended connector is the same as a conventional wiring hole. The wire inside the wiring hole is fixed by the fixing rod on the single-ended connector. The fixing rod is raised and lowered by the threaded connection between it and the single-ended connector. The fixing rod is rotated by the screwing block at the upper end of the fixing rod. This design can fix the wire.

[0008] Preferably, one end of the single-ended connector is equipped with an extension plate, one end of which is connected to the single-ended connector, and the other end of which is connected to a connector rod. The other end of the single-ended connector has a connector hole, and the connector rod is placed inside the connector hole. The connector rod is connected to the single-ended connector via the extension plate. When connecting two single-ended connectors, the connector rod on the extension plate is inserted into the connector hole of the adjacent single-ended connector. The two adjacent single-ended connectors are then fitted together through the cooperation of the connector rod and the connector hole. This design allows for the fitting of two adjacent single-ended connectors.

[0009] Preferably, the limiting frame has a U-shaped cross-section and includes a side plate and a bottom plate. Two side plates are provided and installed on opposite sides of each side plate. Each side plate has a sliding strip, and both sides of the single end have sliding grooves. The limiting frame is slidably connected to the single end through the cooperation of the sliding strip and the sliding grooves. One end of the bottom plate is positioned below the single end, and the other end is positioned below the adjacent single end. The U-shaped limiting frame is installed at the lower end of the single end and slides through the cooperation of the sliding strip on the side plate and the sliding groove on the single end. After two adjacent single ends are in contact, the limiting frame is slid, moving one side of the limiting frame below the adjacent single end, placing both sides of the sliding strip into the sliding grooves of the two single ends, thus limiting the vertical displacement of the two single ends. In cooperation with the connecting rod, the two adjacent single ends are fixed. This design effectively restricts the vertical displacement of the two single ends.

[0010] Preferably, limiting blocks are provided on both sides of the single end, and a stop block is installed on the side plate of the limiting frame. Two limiting blocks are provided on one side of the single end, respectively positioned on both sides of the stop block. Two limiting blocks are installed on each side of the single end, one at the end and the other at the center. A stop block is then installed on the side plate of the limiting frame, with the stop block positioned between the two limiting blocks. The movement distance of the stop block is limited by the two limiting blocks, thereby limiting the sliding distance of the limiting frame. This design prevents the limiting frame from detaching.

[0011] Preferably, the fixing plate has a U-shaped cross-section. A sliding block is installed on the side of the fixing plate, and the fixing plate is slidably connected to the single-end head through the cooperation of the sliding block and the sliding groove. The bottom edge of the fixing plate has a mounting hole, and the bottom surface of the fixing plate has a connecting pipe. The upper end of the connecting pipe passes through the fixing plate and corresponds to the connecting rod. The other end of the connecting pipe is fitted with a bonding plate. After connecting several single-end heads, the fixing plate is installed on the single-end head that is not inserted into the adjacent limiting frame. The sliding block of the fixing plate is inserted into the sliding groove to fix the fixing plate to the single-end head. Then, by pressing the bonding plate against the bottom edge of the fixing plate, the connecting pipe rises above the fixing plate, and the connecting rod is inserted into the connecting pipe to limit the left and right movement of the fixing plate. Then, the fixing plate is fixed to the distribution cabinet by screws passing through the mounting holes on the fixing plate. The bonding plate is pressed by the mounting surface. At this time, the stability of the fixing plate is ensured by the cooperation of the connecting pipe and the fixing plate. This design allows for the installation of an integral copper busbar.

[0012] Preferably, the base plate of the limiting frame is equipped with fixing holes. By installing these holes on the limiting frame and passing screws through them to connect it to the distribution cabinet, one end of the copper busbar is fixed. This design allows for the fixing of both ends of the copper busbar.

[0013] The beneficial effects of this utility model are: the number of wiring holes can be increased according to actual needs to fix the wires, to fit two adjacent single ends, to limit the vertical displacement of the two single ends, to prevent the limiting frame from detaching, to install the overall copper busbar, and to fix both ends of the copper busbar.
