Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a tripping mechanism for a plastic-cased IoT lighting circuit breaker. Background Technology

[0002] The tripping mechanism of a molded case IoT lighting circuit breaker is a key component in realizing the protection function of the circuit breaker. In a molded case circuit breaker, the tripping mechanism is responsible for automatically cutting off the current when a circuit fault is detected, such as an overload or short circuit, thereby protecting the circuit and equipment from damage. This mechanism is equally important for IoT lighting fixtures, ensuring that the fixture can safely shut off under abnormal current conditions, preventing potential fires or safety accidents.

[0003] Traditional circuit breaker tripping mechanisms often rely on indicator lights, displays, or other electronic components to show the status. However, these methods may malfunction under harsh environments or electromagnetic interference, leading to inaccurate status displays. Inaccurate status displays may cause operators to misunderstand the safety status of the circuit, thus neglecting necessary maintenance and inspection. Over time, this may lead to a continuous increase in safety hazards in the circuit system, eventually causing serious accidents. Utility Model Content

[0004] The purpose of this invention is to provide a tripping mechanism for a plastic-cased IoT lighting circuit breaker, which improves safety and solves the problem of poor safety in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A tripping mechanism for a plastic-cased IoT lighting circuit breaker includes a circuit breaker housing, with a connecting copper sheet fixedly connected to the top of the housing and an elastic copper sheet fixedly connected to the bottom of the housing; a fixed plate, the upper end of which is fixedly disposed on the top of the housing, an electromagnet fixedly connected to the lower end of which is fixedly disposed on the lower end, and a contact copper sheet fixedly connected to the lower end of which is slidably connected to the fixed plate and fixedly connected to the upper end of the contact copper sheet; and a movable block slidably disposed on the circuit breaker. Inside the housing, a cylindrical column is fixedly connected to the upper end of the movable block, and a permanent magnet is fixedly connected to the interior of the upper end of the cylindrical column. The cylindrical column is slidably connected to a first contact copper sheet, and the upper end of the cylindrical column is slidably connected to the interior of the lower end of the fixed plate. An electromagnet is slidably connected to the interior of the upper end of the cylindrical column and cooperates with the permanent magnet. A second contact copper sheet is fixedly connected to the upper end of the movable block, and the upper end of the second contact copper sheet contacts the lower end of the second contact copper sheet. The upper end of an elastic copper sheet is fixedly connected to the movable block, and the upper end of the elastic copper sheet is fixedly connected to the lower end of the second contact copper sheet.

[0007] Preferably, the inner walls on both sides of the circuit breaker housing are provided with guide grooves, and the movable block is provided with protrusions on both sides. The protrusions are slidably connected to the guide grooves, and a spring is fixedly connected between the lower end of the protrusion and the bottom of the guide groove.

[0008] Preferably, a temperature sensor is fixedly connected inside the side wall of the circuit breaker housing, and the detection end of the temperature sensor is located on one side of the contact copper sheet.

[0009] Preferably, a sliding groove is provided inside the side wall of the circuit breaker housing, a movable plate is slidably connected inside the sliding groove, and a connecting block is fixedly connected between the side wall of the movable plate and the side wall of the movable block.

[0010] Preferably, the side wall of the movable plate is provided with a groove, a locking block is slidably connected inside the groove, and a spring is fixedly connected between the side wall of the locking block and the inner wall of the groove.

[0011] Preferably, the side wall of the circuit breaker housing is provided with a slot, the slot is connected to a sliding groove, and the slot cooperates with a locking block.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. When the wire is overloaded and the temperature of the first contact copper plate exceeds the rated value set by the temperature sensor, the electromagnet is energized and generates a magnetic force that repels the permanent magnet. The repulsive magnetic force pushes the permanent magnet, which pushes the movable block downward through the cylinder. The protrusion pushes the first spring downward, compressing the first spring. At the same time, the elastic copper plate bends, causing the upper end of the second contact copper plate to separate from the lower end of the second contact copper plate, disconnecting the power connection between the two wires, thus tripping and cutting off the power. When the wire is overloaded and the temperature rises, the temperature sensor can quickly detect the abnormality and trigger the tripping mechanism. This timely response helps to prevent the circuit from overheating and potential safety risks.

[0014] 2. When the movable block slides, the movable plate is driven to slide through the connecting block. When the groove is aligned with the slot, the elasticity of the second spring pushes the locking block out from inside the groove. The locking block slides into the slot, thus indicating that the circuit breaker housing is in the tripped state. By displaying the tripped state, the operator can understand the safety status of the circuit in a timely manner and take corresponding safety measures to prevent safety accidents caused by circuit failure or misoperation, thereby improving the overall system safety.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A tripping mechanism for a plastic-cased IoT lighting circuit breaker includes a circuit breaker housing 001, a connecting copper sheet 101 fixedly connected to the top of the circuit breaker housing 001, and an elastic copper sheet 102 fixedly connected to the bottom of the circuit breaker housing 001; a fixing plate 002, the upper end of which is fixedly disposed at the top of the circuit breaker housing 001, and an electromagnet 201 fixedly connected to the lower end of the fixing plate 002; a contact copper sheet 202 fixedly connected to the lower end of the fixing plate 002; the lower end of the connecting copper sheet 101 is slidably connected to the fixing plate 002 through it; and the lower end of the connecting copper sheet 101 is connected to the contact copper sheet 202 through it. The upper end of contact copper sheet 202 is fixedly connected to a movable block 003, which is slidably disposed inside the circuit breaker housing 001. A cylindrical column 301 is fixedly connected to the upper end of the movable block 003, and a permanent magnet 302 is fixedly connected inside the upper end of the cylindrical column 301. The cylindrical column 301 and contact copper sheet 202 are slidably connected through the cylindrical column 301. The upper end of the cylindrical column 301 is slidably connected to the lower end of the fixed plate 002. An electromagnet 201 is slidably connected to the upper end of the cylindrical column 301. The electromagnet 201 cooperates with the permanent magnet 302. A second contact copper sheet 303 is fixedly connected to the upper end of the movable block 003. The upper end of contact copper sheet 303 contacts the lower end of contact copper sheet 202. The upper end of elastic copper sheet 102 is fixedly connected to movable block 003. The upper end of elastic copper sheet 102 is fixedly connected to the lower end of contact copper sheet 303. The connecting cylinder 301 is made of plastic. The lower end of the copper sheet inside the upper interface end of the circuit breaker housing 001 is fixedly connected to the upper end of connecting copper sheet 101. The upper end of the copper sheet inside the lower interface end of the circuit breaker housing 001 is fixedly connected to the lower end of elastic copper sheet 102. The operator fixes the circuit breaker housing 001 to the inside of the plastic-cased IoT lighting fixture with bolts. The ends of the two connecting wires inside the plastic-shell IoT lamp are fixedly installed inside the upper and lower ports of the circuit breaker housing 001. When the wires are overloaded and the temperature of the contact copper sheet 202 exceeds the rated value, the electromagnet 201 is energized to generate a magnetic force that repels the permanent magnet 302. The repulsive magnetic force pushes the permanent magnet 302, which pushes the movable block 003 downward through the cylinder 301. At the same time, the elastic copper sheet 102 bends, causing the upper end of the second contact copper sheet 303 to separate from the lower end of the first contact copper sheet 202, disconnecting the power connection between the two wires and thus tripping.

[0023] The inner walls on both sides of the circuit breaker housing 001 are provided with guide grooves 103, and the movable block 003 is provided with protrusions 304 on both sides. The protrusions 304 are slidably connected to the guide grooves 103. A spring 104 is fixedly connected between the lower end of the protrusion 304 and the bottom of the guide groove 103. The spring force of the spring 104 pushes the protrusion 304 upward to slide, and at the same time, the protrusion 304 drives the movable block 003 to slide upward.

[0024] A temperature sensor 105 is fixedly connected inside the side wall of the circuit breaker housing 001. The detection end of the temperature sensor 105 is located on the side of the first contact copper sheet 202. The temperature sensor 105 monitors the temperature of the surfaces of the first contact copper sheet 202 and the second contact copper sheet 303.

[0025] The circuit breaker housing 001 has a sliding groove 106 inside its side wall. A movable plate 004 is slidably connected inside the sliding groove 106. A connecting block 401 is fixedly connected between the side wall of the movable plate 004 and the side wall of the movable block 003. When the movable block 003 slides, the movable plate 004 is driven to slide through the connecting block 401.

[0026] The side wall of the movable plate 004 is provided with a groove 402. A locking block 403 is slidably connected inside the groove 402. A spring 404 is fixedly connected between the side wall of the locking block 403 and the inner wall of the groove 402. The elasticity of the spring 404 pushes the locking block 403 out from inside the groove 402.

[0027] The side wall of the circuit breaker housing 001 is provided with a slot 107, which is connected to the slide groove 106. The slot 107 cooperates with the locking block 403. The movable plate 004 slides downward, and when the groove 402 is aligned with the slot 107, the locking block 403 slides into the slot 107, thereby indicating that the circuit breaker housing 001 is in the tripped state.

[0028] In this utility model, the operator fixes the circuit breaker housing 001 to the inside of the plastic-shell IoT lamp with bolts. Then, the ends of the two connecting wires inside the plastic-shell IoT lamp are fixed and installed inside the upper and lower ports of the circuit breaker housing 001 respectively. The electromagnet 201 is in the de-energized state and does not generate repulsive magnetic force. Then, the operator manually presses the locking block 403, so that the locking block 403 slides from the slot 107 to the groove 402. Then, the spring force of the spring 104 pushes the protrusion 304 to slide upward. At the same time, the protrusion 304 drives the movable block 003 to slide upward. The elastic copper sheet 102 extends from the bent state, so that the cylinder 301 passes through the contact copper sheet 202 and slides to the lower end of the fixed plate 002. The electromagnet 201 contacts the permanent magnet 302, and at the same time, the upper end of the contact copper sheet 203 contacts the lower end of the contact copper sheet 202, thereby establishing an electrical connection.

[0029] When the wire is overloaded and the temperature of the contact copper plate 202 exceeds the rated value set by the temperature sensor 105, the electromagnet 201 is energized to generate a magnetic force that repels the permanent magnet 302. The repulsive magnetic force pushes the permanent magnet 302, which pushes the movable block 003 downward through the cylinder 301. The protrusion 304 pushes the spring 104 downward, causing the spring 104 to compress. At the same time, the elastic copper plate 102 bends, causing the upper end of the contact copper plate 203 to separate from the lower end of the contact copper plate 202, disconnecting the power connection between the two wires, thereby tripping and disconnecting the power. When the movable block 003 slides, it drives the movable plate 004 to slide through the connecting block 401. When the groove 402 is aligned with the slot 107, the elasticity of the spring 204 pushes the locking block 403 out of the groove 402. The locking block 403 slides into the slot 107, thus indicating that the circuit breaker housing 001 is in a tripped state.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
