Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a circuit breaker anti-loosening terminal block. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and closing, carrying, and interrupting abnormal circuit current within a specified time. A terminal block is an accessory product used to achieve electrical connection. It is usually composed of a metal plate encapsulated in insulating plastic, with holes at both ends for inserting wires, and is fastened or loosened by screws. The circuit breaker is responsible for the on / off control and protection of the circuit, while the terminal block provides a reliable connection between the wire and the circuit breaker. The two work together to ensure the safe operation of the circuit.

[0003] Currently, when using terminal blocks, wires are usually tightened or loosened with screws. When the wires are subjected to external tension, the connection between the wire and the screw is prone to rotation, which can cause the wires to loosen, resulting in data transmission errors, communication interruptions, or control failures, thus reducing the efficiency of the terminal blocks. To address this, a circuit breaker anti-loosening terminal block is proposed. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an anti-loosening terminal block for circuit breakers, thereby overcoming the shortcomings of existing solutions.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a circuit breaker anti-loosening terminal, including a terminal body and a mounting plate fixedly connected to the top, wherein multiple sets of first movable rods and multiple sets of second movable rods are slidably connected to the top of the mounting plate, the first movable rods and the second movable rods are arranged in segments, the two ends of the first movable rods are fixedly connected to a first clamping rod, the two ends of the second movable rods are fixedly connected to a second clamping rod, and the mounting plate is provided with an adjusting component for driving the first movable rods and the second movable rods to move horizontally.

[0006] A further improvement is that: the inner cavity of the terminal body is fixedly connected to multiple sets of pressure plates, and the top of the pressure plates is threadedly connected to a fastening bolt.

[0007] A further improvement is that: a first connecting rod is fixedly connected between multiple sets of the first movable rods to facilitate the synchronous movement of the first movable rods, and a first through groove is provided on the side wall of the second movable rod to facilitate the movement of the first connecting rod.

[0008] A further improvement is that a second connecting rod is fixedly connected between multiple sets of the second movable rods to facilitate the synchronous movement of the second movable rods, and a second through groove is provided on the first movable rod to facilitate the movement of the second connecting rod.

[0009] A further improvement is made in that: the adjusting component includes a first support cylinder and a second support cylinder, the first support cylinder is fixedly connected to the side wall of a set of first movable rods, the second support cylinder is fixedly connected to the side wall of a set of second movable rods, both sides of the inner cavity of the mounting plate are rotatably connected to threaded rods, the first support cylinder and the second support cylinder are both threadedly connected to the threaded rods, and the side wall of the mounting plate is rotatably connected to a rotating block that drives the threaded rods to rotate.

[0010] A further improvement is that rubber pads for protecting the wires are fixedly connected to the side walls of both the first clamping rod and the second clamping rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a mounting plate on the terminal body, and setting a first movable rod and a second movable rod on the mounting plate respectively, the first movable rod and the second movable rod support the first clamping rod and the second clamping rod respectively.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] according to Figure 1-3 As shown, this embodiment proposes a circuit breaker anti-loosening terminal block, including a terminal body 100 and a mounting plate 200 fixedly connected to the top. The mounting plate 200 supports a first movable rod 210 and multiple sets of second movable rods 230. Multiple sets of first movable rods 210 and multiple sets of second movable rods 230 are slidably connected to the top of the mounting plate 200. The first movable rods 210 and second movable rods 230 respectively drive the first clamping rods 211 and second clamping rods 231 to move. The first movable rods 210 and second movable rods 230 are arranged in segments. Specifically, each set of first movable rods 210 and second movable rods 230 is close to each other and used in conjunction. The first clamping rods 211 are fixedly connected to both ends of the first movable rods 210, and the second clamping rods 231 are fixedly connected to both ends of the second movable rods 230. The wires are clamped by the first clamping rods 211 and second clamping rods 231. The mounting plate 200 is provided with an adjusting member for driving the first movable rods 210 and second movable rods 230 to move horizontally.

[0021] according to Figure 1 and Figure 2 As shown, multiple sets of pressure plates 110 are fixedly connected to the inner cavity of the terminal body 100. The top of the pressure plate 110 is threaded with a fastening bolt 120. The wire is fixed to the pressure plate 110 by the fastening bolt 120, so that the circuit breaker is connected to the terminal.

[0022] according to Figure 2 and Figure 3As shown, a first connecting rod 220 is fixedly connected between multiple sets of first movable rods 210 to facilitate the synchronous movement of the first movable rods 210. The side wall of the second movable rod 230 is provided with a first through groove to facilitate the movement of the first connecting rod 220. Through the setting of the first connecting rod 220, multiple sets of first movable rods 210 can move synchronously.

[0023] according to Figure 2 and Figure 3 As shown, a second connecting rod 240 is fixedly connected between multiple sets of second movable rods 230 to facilitate the synchronous movement of the second movable rods 230. A second through groove is provided on the first movable rod 210 to facilitate the movement of the second connecting rod 240. The arrangement of the second connecting rod 240 enables the multiple sets of second movable rods 230 to move synchronously.

[0024] according to Figure 2 and Figure 3 As shown, the adjusting component includes a first support cylinder 221 and a second support cylinder 241. The first support cylinder 221 is fixedly connected to the side wall of a set of first movable rods 210, and the second support cylinder 241 is fixedly connected to the side wall of a set of second movable rods 230. Threaded rods 251 are rotatably connected to both sides of the inner cavity of the mounting plate 200. Both the first support cylinder 221 and the second support cylinder 241 are threadedly connected to the threaded rods 251. A rotating block 250, which drives the threaded rods 251 to rotate, is rotatably connected to the side wall of the mounting plate 200. The adjustment mechanism is achieved through the first... The support cylinder 221 drives the first movable rod 210 to move, and the second support cylinder 241 drives the second movable rod 230 to move. Specifically, since the first support cylinder 221 and the second support cylinder 241 are respectively threadedly connected to the corresponding threaded rod 251, the threaded rod 251 can drive the first support cylinder 221 and the second support cylinder 241 to move when rotating, and bring the first support cylinder 221 and the second support cylinder 241 closer to each other, thereby realizing the clamping of the wire by the first clamping rod 211 and the second clamping rod 231.

[0025] according to Figure 1 As shown, rubber pads 260 for protecting the wire are fixedly connected to the side walls of the first clamping rod 211 and the second clamping rod 231. The rubber pads 260 enable the first clamping rod 211 and the second clamping rod 231 to protect the wire when clamping it.

[0026] The working principle of this application is as follows: First, the wire is placed on the pressure plate 110, and the wire is fixed to the pressure plate 110 by rotating the fastening bolt 120. Then, a set of rotating blocks 250 are rotated, which drives the threaded rod 251 to rotate. The threaded rod 251 drives the first support cylinder 221 to move horizontally, and the first support cylinder 221 drives the first movable rod 210 to move. Multiple sets of first movable rods 210 move synchronously through the first connecting rod 220. At this time, the first movable rod 210 drives the first clamping rod 211. The rotating block 250 at the other end is translated and then rotated, so that the threaded rod 251 at the other end can drive the second support cylinder 241 to move. The second support cylinder 241 drives the second movable rod 230 to translate. Multiple sets of second movable rods 230 move synchronously through the second connecting rod 240, and the second movable rod 230 drives the second clamping rod 231 to move, so that the first clamping rod 211 and the second clamping rod 231 move relative to each other, and the first clamping rod 211 and the second clamping rod 231 clamp and limit the wire through the rubber pad 260, thus completing the use.
