Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, specifically a circuit breaker terminal block. Background Technology
[0002] Terminal blocks are accessories used to achieve electrical connections. They facilitate the connection of wires, ensuring that current can be smoothly conducted between different wires. When connecting wires to some circuit breakers, they are first connected through terminal blocks, and then connected to the circuit breaker through the terminal blocks. These terminal blocks are usually made of copper, with a round tube at one end for wiring and a connector at the other end for connecting to the circuit breaker. When the wire is inserted into the round tube, the tube can be pressed and deformed with pliers to fix the wire inside. However, if the wire is not securely fixed after the tube is deformed, the tube cannot be reused. Furthermore, if the pressing pressure is uneven during the pressing process, the tube may not be flattened, leaving one side of the tube open and allowing dust to enter. Utility Model Content
[0003] The purpose of this utility model is to provide a circuit breaker terminal block to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a circuit breaker terminal block, comprising a fixing member for connecting and fixing wires and a terminal block mounted on the fixing member for insertion into a circuit breaker interface. A mating seat is fixedly connected to the terminal block, and a mating ring is fixedly connected to the mating seat. An external thread is fixedly connected to the outer wall of the mating ring. A cavity is formed on the fixing member, and an internal thread that mates with the mating ring is fixedly connected to the cavity. The mating seat and the fixing member can be disassembled and assembled through the engagement of the external thread and the internal thread.
[0005] As a preferred embodiment of this utility model, the fixing member is fixedly connected with a foldable part, and the cavity can be easily bent and closed from the foldable part.
[0006] As a preferred embodiment of this utility model, the fixing member is fixedly connected with a positioning rib.
[0007] As a preferred embodiment of this utility model, the positioning rib is provided with anti-slip texture.
[0008] As a preferred embodiment of this utility model, the terminal block is fixedly connected with teeth.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the docking seat, external thread and internal thread of this utility model can facilitate the quick replacement of the fastener. Even if the fastener is deformed or damaged, it can be disassembled and replaced to ensure that the docking seat and the terminal can continue to be used, avoiding waste. The easy-bend part facilitates the bending of the fastener and prevents the phenomenon of small holes in the cavity after the fastener is flattened. The positioning rib facilitates the positioning and installation of heat shrink tubing between the wire and the fastener, improving the overall aesthetics. 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] Please see Figures 1 to 3 This utility model provides a technical solution: a circuit breaker terminal block, including a fixing member 1 and a terminal block 3 that is mounted on the fixing member 1 and can be inserted into the circuit breaker interface. A mating seat 2 is fixedly connected to the terminal block 3, and a mating ring 7 is fixedly connected to the mating seat 2. An external thread 8 is fixedly connected to the outer wall of the mating ring 7. A cavity 4 is opened on the fixing member 1, and an internal thread 9 that mates with the mating ring 7 is fixedly connected in the cavity 4. The mating seat 2 and the fixing member 1 can be fixed by the mating of the external thread 8 and the internal thread 9.
[0016] The fastener 1 is fixedly connected with a bendable part 5, which allows the cavity 4 to be bent and closed, making it easy to compress the wire.
[0017] The fixing member 1 is fixedly connected with a positioning rib 6. After the wire is fixed to the fixing member 1, a heat shrink sleeve is sleeved between the fixing member 1 and the wire. The heat shrink sleeve can be positioned and installed according to the positioning rib 6.
[0018] Among them, the terminal 3 is fixedly connected with teeth 10.
[0019] Specifically, during wiring, the wire can be inserted into the cavity 4 and then pressed against the bottom of the cavity 4. Using pliers, clamp the fixing part 1 from two directions away from the easily bent part 5. The fixing part 1 will be easily bent and deformed from the easily bent part 5 to press the wire. Then, after putting heat shrink tubing on the fixing part 1, align it with the positioning rib 6 for installation. If the fixing part 1 is deformed after being pressed or if the wire is still loose after being inserted into the cavity 4, the wire can be pulled out and the fixing part 1 can be twisted to detach the fixing part 1 from the docking seat 2. Replace the deformed fixing part 1. After the wiring is completed, insert 3 into the wiring port of the circuit breaker.
