Description

Technical Field

[0001] This utility model relates to a circuit breaker. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is somewhat blurred; generally, circuit breakers above 3kV are referred to as high-voltage electrical appliances.

[0003] To achieve the overload circuit breaking function, the terminal block needs to be connected to the circuit board. After the circuit board detects the overload, it will disconnect the circuit. However, the existing terminal block and the circuit board are usually connected by wires. If the wires are connected, both ends need to be connected, which is quite troublesome. In addition, the wires will take up space inside the circuit breaker. Utility Model Content

[0004] In summary, to overcome the shortcomings of the prior art, this utility model provides a circuit breaker that is easy to connect to the terminal block and circuit board and occupies little space.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circuit breaker, comprising a base, an operating component, a connecting component, and a circuit board, wherein the connecting component comprises a moving contact, a stationary contact, and a terminal block, the stationary contact being connected to the terminal block, the stationary contact having a connector on the side facing the circuit board, and the circuit board having a connector socket adapted to the connector.

[0006] With this setup, during installation, simply insert the connector on the stationary contact plate into the connection socket on the circuit board to complete the connection. When connecting, only the end of the connector needs to be connected to the circuit board, while the other end of the connector is directly integrated with the stationary contact plate and does not need to be connected separately. This makes installation convenient, and after installation, the connector will not stick up like an electrical wire, taking up space inside the circuit breaker.

[0007] Furthermore, the connection port is located on the side of the circuit board, and the connection port is configured to penetrate the side of the circuit board.

[0008] With this configuration, the width of the connector is no longer limited, and the connector can be positioned further out. Even if manufacturing errors cause misalignment, it will not affect the insertion and installation of the connector.

[0009] Furthermore, guide bevels are provided on both sides of the end of the connector.

[0010] With this setting, the connector becomes tapered after the guide angle is set, making insertion and installation smoother.

[0011] Furthermore, the circuit board is located at the bottom of the base, the base is provided with a connection hole that matches the connector at the position corresponding to the connection socket, the stationary contact piece is provided with a bent plate that matches the connection hole, and the connector is located at the end of the bent plate.

[0012] With this setup, the connector is first passed through the connection hole and then into the connection socket on the circuit board at the bottom of the base during installation. The fit between the connector and the connection hole provides a stable effect, while the bent plate ensures that the stationary contact piece fits the base, making it even more stable.

[0013] Furthermore, the base is provided with a mounting groove, the terminal block is located in the mounting groove, the stationary contact piece is provided with a mounting plate, and the two ends of the stationary contact piece are bent into a Z-shape on the mounting plate.

[0014] With this configuration, the mounting slot can stabilize the connection of the terminal block. At the same time, the mounting plate in the mounting slot can work with the connector to clamp the two together, achieving a clamping effect and making the whole structure more stable.

[0015] Furthermore, the width of the connector is smaller than the width of the stationary contact piece.

[0016] This design reduces the width of the slot on the circuit board while maintaining the strength of the circuit board, thus preserving the width of the stationary contact piece without affecting its function. Attached Figure Description

[0022] This specific embodiment is merely an explanation of the present embodiment and is not intended to limit the present embodiment. After reading this specification, those skilled in the art can make modifications to the present embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present embodiment.

[0023] Referring to the accompanying drawings, the present invention provides the following technical solution: a circuit breaker, comprising a base 1, an operating component 2, a connecting component 3, and a circuit board 4. The connecting component 3 includes a moving contact 301, a stationary contact 302, and a terminal block 303. The stationary contact 302 is connected to the terminal block 303. The stationary contact 302 has a connector 3021 on the side facing the circuit board 4. The circuit board 4 has a connection socket 401 adapted to the connector 3021.

[0024] With this configuration, during installation, simply insert the connector 3021 on the stationary contact piece 302 into the connection socket 401 on the circuit board 4 to complete the connection between the two. During connection, only the connection between the end of the connector 3021 and the circuit board 4 needs to be handled. The other end of the connector 3021 is directly integrated with the stationary contact piece 302 and does not need to be connected separately. This makes installation convenient, and after installation, the connector 3021 will not arch up like an electrical wire, occupying space inside the circuit breaker.

[0025] In this preferred embodiment, the connection port 401 is located on the side of the circuit board 4, and the connection port 401 is disposed through the side of the circuit board 4.

[0026] With this configuration, the width of the connector 401 is no longer limited, and the connector 3021 can be positioned further out. Even if there are errors in the manufacturing process that cause misalignment, it will not affect the insertion and installation of the connector 3021.

[0027] In this preferred embodiment, guide bevels 3022 are provided on both sides of the end of the connector 3021.

[0028] With this setting, after setting the guide angle 3022, the connector 3021 will be tapered, making insertion and installation smoother.

[0029] In this preferred embodiment, the circuit board 4 is located at the bottom of the base 1, the base 1 is provided with a connection hole 101 that is adapted to the connector 3021 at the position corresponding to the connection socket 401, the stationary contact piece 302 is provided with a bent plate 3023 that is adapted to the connection hole 101, and the connector 3021 is located at the end of the bent plate 3023.

[0030] With this configuration, when installing the connector 3021, it first passes through the connection hole 101 and then enters the connection socket 401 on the circuit board 4 at the bottom of the base 1. The connector 3021 and the connection hole 101 work together to achieve a stable effect, while the bent plate 3023 can ensure that the stationary contact piece 302 can fit against the base 1, making it more stable.

[0031] In this preferred embodiment, the base 1 is provided with a mounting groove 102, the terminal block 303 is located in the mounting groove 102, the stationary contact piece 302 is provided with a mounting plate 3024, and the two ends of the stationary contact piece 302 are bent into a Z-shape at the mounting plate 3024.

[0032] With this configuration, the mounting slot 102 can stably connect the terminal block 303. At the same time, the mounting plate 3024 in the mounting slot 102 can cooperate with the connector 3021 to clamp the position between the two, achieving a clamping effect and making the whole more stable.

[0033] In this preferred embodiment, the width of the connector 3021 is smaller than the width of the stationary contact piece 302.

[0034] This configuration reduces the width of the slot on the circuit board 4 to ensure the strength of the circuit board 4 while retaining the width of the stationary contact piece 302, thus not affecting the function of the stationary contact piece 302.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, the scope of protection of the present invention is not limited thereto.
