Description

Technical Field

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

[0002] Fixed circuit breakers are widely used low-voltage electrical components in power systems. They are mainly used for connecting, carrying, and disconnecting circuits, and can provide reliable protection for lines and equipment under fault conditions such as overload and short circuit. During the installation and use of circuit breakers, their terminal blocks are key components for achieving electrical connections with external cables.

[0003] In existing technologies, the terminal blocks of fixed circuit breakers, especially those that need to be adjusted or replaced according to the wiring scheme, are usually installed by tightening screws. This traditional connection method has some shortcomings in practical operation. For example, when the circuit breaker is installed in a small distribution cabinet, it becomes very difficult to tighten or loosen the screws with tools. This not only reduces the efficiency of wiring and subsequent maintenance, but also increases the labor intensity of construction.

[0004] Furthermore, for safety reasons, the terminal blocks of circuit breakers need to have good insulation protection to prevent accidental electric shock to operators or short circuits caused by external conductive objects falling in. However, many circuit breakers currently have relatively simple protective structures, either open designs or only equipped with simple snap-on covers. The locking mechanism of this type of protection is unreliable and can easily loosen under vibration or accidental contact, failing to provide continuous and effective insulation and physical protection, posing serious safety hazards.

[0005] Therefore, this utility model proposes a fixed circuit breaker and its terminal block to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of inconvenient assembly and disassembly of the terminal block and unreliable locking of the insulation protection structure in the existing fixed circuit breaker and its terminal block, this utility model aims to provide a fixed circuit breaker and its terminal block with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a fixed circuit breaker and its terminal block, including a body, a horizontal terminal block, an installation mechanism, and a switching mechanism.

[0008] The horizontal terminal block is slidably disposed within the machine body. The mounting mechanism includes a hemisphere disposed on the horizontal terminal block and a magnet disposed within the machine body. The hemisphere and the magnet are combined by magnetic attraction to achieve detachable fixing of the horizontal terminal block.

[0009] The switching mechanism includes an insulating plate one fixed to the body and an insulating plate two rotatably connected to the body via a U-shaped rod. The insulating plate one has a locking groove, and the insulating plate two has a locking block. The insulating plate one and the insulating plate two are locked together by the locking groove and the locking block.

[0010] Preferably, the horizontal terminal block is provided with a fixing block, the fixing block is provided with a mounting groove, the hemisphere is disposed in the mounting groove, and a spring is provided between the hemisphere and the bottom of the mounting groove.

[0011] Preferably, the switching mechanism further includes a mounting plate fixed to the body by screw two, the mounting plate being provided with a connecting post, and the insulating plate being fixed to the connecting post.

[0012] Preferably, as a specific implementation, the U-shaped rod is rotatably connected to the mounting plate.

[0013] Preferably, both the first insulating plate and the second insulating plate are provided with sliding grooves. The switching mechanism also includes a locking rod, which can be inserted into the mutually aligned sliding grooves for further locking the first insulating plate and the second insulating plate.

[0014] Preferably, the fixed circuit breaker and its terminal block further include a vertical connecting busbar, which is fixed to the body by screws to provide multi-directional wiring.

[0015] Preferably, the fixed circuit breaker and its terminal block further include a housing, which is disposed on the upper part of the body and is used to protect the entire device.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome and inefficient installation and disassembly of existing terminal blocks, which are usually fastened with screws, by setting up an installation mechanism in which a magnetic hemisphere and a magnetic block are magnetically attracted to each other. It achieves the technical effect of enabling quick and tool-free installation and disassembly of horizontal terminal blocks, greatly improving the convenience and efficiency of wiring and maintenance work.

[0017] 2. This utility model solves the problems of simple protective structure, unreliable locking, and low safety protection level of the circuit breaker terminal by setting an openable switching mechanism composed of two insulating plates and fixing it by using the cooperation of the locking block and the locking groove and the insertion and locking of the locking rod. It achieves the technical effect of increasing the electrical insulation distance, providing reliable physical isolation for the wiring part, effectively preventing accidental contact, and significantly improving the overall safety of the device.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Example: Please refer to Figures 1 to 5 This utility model provides a fixed circuit breaker and its terminal block, which aims to solve the problems of inconvenient disassembly and assembly of the terminal block and unreliable locking of the insulation protection structure in the prior art.

[0022] like Figure 1 and Figure 2As shown, this fixed circuit breaker and its terminal block include a body 1, which serves as the mounting base for the entire device. A connection groove 203 is provided on the body 1. A housing 311 is also provided on the upper part of the body 1. A vertical connecting bar 201 and a switching mechanism 3 are fixedly connected to the body 1. A detachable horizontal terminal block 204 and a mounting mechanism 2 for easy assembly and disassembly are also provided. The horizontal terminal block 204 is slidably disposed within the connection groove 203 of the body 1. The circuit breaker includes a hemispherical sphere 208 mounted on a horizontal terminal block 204 and a magnetic block 209 mounted inside the body 1. The hemispherical sphere 208 is magnetic and magnetically attracted to the magnetic block 209. The switching mechanism 3 is used to provide insulation protection for the wiring parts of the circuit breaker. The switching mechanism 3 includes an insulating plate 304 and an insulating plate 307 fixed to the body 1. The insulating plate 307 is rotatably connected to the body 1 via a U-shaped rod 306. The insulating plate 304 and the insulating plate 307 can be locked together after being closed.

[0023] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the installation mechanism 2 and switching mechanism 3 of the fixed circuit breaker and its terminal block have a specific structural cooperation and connection relationship.

[0024] Please refer to the following carefully. Figure 2 and Figure 3 The following is a detailed description of the installation mechanism 2. A fixing block 205 is fixedly connected to the horizontal terminal block 204. The fixing block 205 has an installation groove 206. A spring 207 is installed in the installation groove 206. A hemispherical ball 208 is connected to one end of the spring 207 away from the bottom of the installation groove 206. A magnet block 209 corresponding to the position of the hemispherical ball 208 is fixed on the inner wall of the body 1. When the horizontal terminal block 204 is pushed into the connection groove 203, the hemispherical ball 208 is attracted by the magnetic force of the magnet block 209 and moves and compresses the spring 207. Thus, a quick and stable detachable connection is achieved through magnetic attraction. This structure ensures the convenience of installing the horizontal terminal block 204.

[0025] Please refer to the following carefully. Figure 4 and Figure 5The switching mechanism 3 is described in detail below. A mounting plate 301 is fixedly connected to the outer side of the body 1 via screw 302. A connecting post 303 is fixed to the mounting plate 301. An insulating plate 304 is fixed to the connecting post 303. A U-shaped rod 306 is rotatably connected to the mounting plate 301. An insulating plate 307 is fixedly connected to the end of the U-shaped rod 306 away from the mounting plate 301. An engaging groove 305 is provided on the insulating plate 304, and a corresponding engaging groove 305 is provided on the insulating plate 307. A locking block 308 is provided. When the U-shaped rod 306 is rotated to close the second insulating plate 307, the locking block 308 and the locking groove 305 cooperate to achieve initial locking. At the same time, both the first insulating plate 304 and the second insulating plate 307 are provided with sliding grooves 309. The locking rod 310 can be inserted into the aligned sliding grooves 309 to finally and firmly lock the first insulating plate 304 and the second insulating plate 307. This double locking structure ensures the reliability of insulation protection.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to facilitate multi-directional wire connections, this fixed circuit breaker and its terminal block further include a vertical connecting bar 201, please refer to... Figure 2 The vertical cable tray 201 is fixedly connected to the outer surface of the body 1 by screw 202. The vertical cable tray 201 and the horizontal terminal block 204 cooperate with each other to provide flexible wiring options for the access of external cables, making the cable storage more reasonable and orderly.

[0027] As another preferred implementation, to enhance the overall protection of the internal components of the circuit breaker, please refer to... Figure 1 The upper part of the body 1 is also fixedly connected to the shell 311, which covers the top of the body 1 and can effectively prevent dust or foreign objects from falling into the body 1, thereby improving the operational stability and service life of the entire device.

[0028] Working principle: A vertical connector 201 is mounted on the outside of the machine body 1, and is fixed to the vertical connector 201 by screws 202. A connecting groove 203 is also provided on the machine body 1. The horizontal connector 204 can slide on the inner wall of the connecting groove 203.

The hemispherical ball 208, being magnetic, can cooperate with the magnet 209 installed inside the body 1. The hemispherical ball 208 can be attracted by the magnet 209, at which point the spring 207 will be stretched. When the horizontal terminal block 204 needs to be removed, the operator only needs to pull the horizontal terminal block 204 to pull it out. This allows the vertical terminal block 201 and the horizontal terminal block 204 to be conveniently installed through the installation mechanism 2. Through the cooperation of the two, the wires can be reasonably stored. Mounting plates 301 are fixed to both sides of the outer casing 1 by screws 302. Connecting posts 303 are provided on the outer side of the mounting plates 301, and insulating plates 304 are fixed to the outer side of the connecting posts 303.

The other end of the U-shaped rod 306 is connected to the insulating plate 307. Two locking blocks 308 are installed on the outer side of the insulating plate 307, which can engage with the insulating plate 304. The locking groove 305 on the 4 is used for initial locking. Sliding grooves 309 are also provided on the first insulating plate 304 and the second insulating plate 307. By inserting the locking rod 310 into the sliding groove 309, the first insulating plate 304 and the second insulating plate 307 can be further fixed. At the same time, a housing 311 is also installed on the top of the body 1. The function of the first insulating plate 304 and the second insulating plate 307 is to increase the insulation distance. With the cooperation of the switching mechanism 3, it can play a protective role.
