Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a test fixture compatible with circuit breakers. Background Technology

[0002] A circuit breaker is an electrical device that automatically disconnects a circuit, primarily used to protect circuits from overloads (excessive current), short circuits, and other faults. It acts like a "safety guardian" in the circuit, quickly cutting off the circuit when an abnormally large current occurs, preventing serious consequences such as overheating of wires, equipment damage, or even fire.

[0003] However, in the existing technology, some devices and fixtures are not fixed stably, which may cause the circuit breaker to move or fall accidentally during the test, increasing the risk of electric shock to personnel. It may also lead to poor contact, which increases the contact resistance and generates too much heat, affecting the performance of the circuit breaker. As a result, the test data cannot accurately reflect the parameters of the circuit breaker under normal operating conditions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a compatible circuit breaker test fixture. This fixture allows for rapid testing by fixing the circuit breaker in place, reducing the time spent on manual adjustment and repositioning. This reduces the failure rate of probes and the frequency of replacement due to probe damage, thereby reducing the cost of product testing.

[0005] To achieve the above objectives, a compatible circuit breaker test fixture is provided, comprising a housing, a base fixedly connected to the top of the housing, a plurality of support plates fixedly connected to the top of the base, metal collars provided inside the support plates, two clamping plates slidably connected to the top of the support plates, two connecting rods slidably connected inside the clamping plates, a drive rod fixedly connected to one end of the clamping plate, and a drive assembly for power output fixedly connected to the output end of the drive rod.

[0006] According to the compatible circuit breaker test fixture, the drive assembly includes a third motor, the output of which is fixedly connected to the outside of the drive rod.

[0007] According to the compatible circuit breaker test fixture, a support column is fixedly connected to the top of the housing, and a controller is fixedly connected to the outside of the support column.

[0009] According to the compatible circuit breaker test fixture, a slider is slidably connected to the outside of the electric guide rail, and a second motor is fixedly connected to the top of the slider.

[0010] According to the compatible circuit breaker test fixture, the slider is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to a rocker arm, the bottom of the slider is fixedly connected to a fixing column, and the front side of the slider is rotatably connected to a turntable.

[0011] According to the compatible circuit breaker test fixture, a spring is sleeved on the outside of the fixed column, a probe is rotatably connected to the bottom of the fixed column, a collar is detachably connected to the outside of the fixed column, and a limit block is fixedly connected to the outside of the collar.

[0012] According to the compatible circuit breaker test fixture, the limiting block is detachably connected to a locking block on the outside, and the housing is slidably connected to a storage cabinet inside. Beneficial effects

[0013] 1. Place the circuit breaker on the metal collar at the top of the base, and drive the third motor to move the clamp plate on the connecting rod in conjunction with the drive rod, so as to fix the circuit breaker.

Multiple support plates 3 are fixedly connected to the top of the base 2. Metal rings 13 are provided inside the support plates 3. Two clamping plates 14 are slidably connected to the top of the support plates 3 to ensure that the workpiece maintains the correct position during processing, prevent the workpiece from moving or deforming, thereby improving processing accuracy and stability. Two connecting rods 15 are slidably connected inside the clamping plates 14. A drive rod 16 is fixedly connected to one end of the clamping plate 14 to transmit force and motion, transferring power from one place to another. A drive component for power output is fixedly connected to the output end of the drive rod 16.
