Description

Technical Field

[0001] The utility model belongs to a detection tool, in particular to a magnetic switch pulse detection tool. Background Art

[0002] The car starter is a key component to ensure the smooth start of the car. The starter uses the electrical energy in the battery to drive the motor to work, and then drive the engine to start smoothly. The electromagnetic switch in the car starter plays a vital role. When the ignition switch is turned to the start position, the electromagnetic switch is energized, and the internal pull-in coil will generate electromagnetic attraction to pull the movable iron core. This step not only makes the drive gear of the starter move forward and mesh with the ring gear of the engine flywheel, but also connects the main circuit of the starter at the same time. A large current flows from the battery to the motor part of the starter. The motor rotates, driving the engine flywheel to rotate and starting the engine. During the starting process, there is also a retaining coil in the electromagnetic switch. The retaining coil is energized to maintain the electromagnetic attraction and ensure that the iron core and the drive gear remain in the meshing position until the start is completed. The engine starts successfully, the circuit is disconnected, the electromagnetic attraction disappears, and the drive gear is separated from the flywheel ring gear under the action of the reset spring. During the production process, it is easy to have problems such as the pull-in coil cannot drive the movable iron core to move after the electromagnetic switch is energized, the retaining coil cannot provide sufficient holding force for the movable iron core, and the movable iron core cannot be reset after power failure. Traditional testing requires assembling the electromagnetic switch and the motor, and then detecting the start and stop of the motor to achieve the detection purpose. This method increases the detection complexity and it is difficult to determine whether the problem lies with the electromagnetic switch. The detection operation becomes more difficult after assembly. If a problem is found, the electromagnetic switch needs to be removed and replaced or repaired, which increases the workload and time cost and has low detection efficiency.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

The utility model has a simple structure and can directly detect the magnetic switch without assembling the magnetic switch and the motor, thereby reducing the complexity of detection and directly judging whether the magnetic switch has a fault, thereby improving detection efficiency and reducing workload and time cost.
