Description

Technical Field

[0001] This utility model relates to the technical field of magnetic switch testing, and in particular to a magnetic switch life testing device. Background Technology

[0002] Magnetic switches, as important electronic components, are widely used in industrial automation, the automotive industry, consumer electronics, military, energy, medical, and data processing, among other fields. A magnetic switch is a switching device that uses changes in a magnetic field to control the on / off state of a circuit. The working principle of a magnetic switch is based on the interaction between a magnet and a magnetic sensing element. When a magnet approaches the magnetic sensing element, the magnetic field within the element changes, triggering the switch. Specifically, the magnetic sensing element inside the switch (such as a Hall effect sensor, reed switch, or magnetic diode) senses the change in the magnetic field and generates a corresponding electrical signal. This signal controls the closing or opening of the switch contacts, thus controlling the circuit's on / off state. Currently, magnetic switches require testing before leaving the factory to ensure their lifespan meets requirements; however, current testing equipment suffers from low testing efficiency.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

These terms are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] This utility model discloses a magnetic switch life detection device, such as... Figure 1-5 As shown, it includes a power supply 1, a base 2, and a controller 3. The power supply 1 is connected to 220V AC power and outputs 12V DC power. The power supply 1 is electrically connected to the controller 3, which can be a PCB circuit board. The base 2 is equipped with a housing 41, and an electromagnet 4 is installed inside the housing 41. The controller 3 is electrically connected to the electromagnet 4. A 555 timer chip is soldered onto the controller 3. The 12V power supply 1 is powered by the 555 timer chip. The 555 timer chip outputs an H / L signal that changes every 2 seconds, controlling the DC relay of the power supply 1 to energize the coil and generate an intermittent 150mT magnetic field.

[0024] Meanwhile, multiple insertion slots are provided on both opposite sides of the outer casing 41. In this embodiment, the number of insertion slots is preferably 20 or 30. Magnetic switches 5 are inserted into the insertion slots, and the magnetic switches 5 are connected to the insertion slots. The magnetic switches 5 are located on one side of the electromagnet 4 and are electrically connected to the power supply 1. One end of the magnetic switches 5 is connected to the positive terminal of the power supply 1, and the other end is connected to the negative terminal of the power supply 1. When the electromagnet 4 is energized and generates a magnetic field, the magnetic switches 5 close. When the electromagnet 4 is de-energized and the electromagnetic field disappears, the magnetic switches 5 open, thereby controlling the on / off state of the magnetic switches 5. Each action takes approximately 2 seconds. In addition, each magnetic switch 5 is electrically connected to a load module 21, which is connected in series with the magnetic switch 5. The load module 21 is a load resistor with a resistance of 500Ω. Furthermore, the electromagnet 4 is electrically connected to a counter 22. When the electromagnet 4 is energized once, the counter 22 counts once, thereby indirectly obtaining the number of times the magnetic switches 5 close and open.

[0025] In addition, each magnetic switch 5 is electrically connected to an indicator light 6. The magnetic switch 5 and the indicator light 6 are connected in series. The indicator light 6 is connected in series with a 680Ω resistor and then in parallel with the load module 21. When the magnetic switch 5 is closed, the indicator light 6 lights up. When the magnetic switch 5 is open, the indicator light 6 turns off. The indicator light 6 can preferably be an LED. When the indicator light 6 is constantly lit or not lit, it indicates that the magnetic switch 5 is damaged, thus determining the lifespan of the magnetic switch 5.

[0026] In addition, to facilitate the replacement of the magnetic switch 5, multiple sockets 23 are fixedly installed on the base 2. The sockets 23 are electrically connected to the power supply 1. The magnetic switch 5 is electrically connected to a wire 51. One end of the wire 51 is electrically connected to the magnetic switch 5, and the other end of the wire 51 is equipped with a plug. The plug and the socket 23 are electrically connected. When the plug is plugged into the socket 23, the magnetic switch 5 is electrically connected to the power supply 1. After the test is completed, the tester unplugs the plug from the socket 23 and pulls the magnetic switch 5 out of the socket slot. The tested magnetic switch 5 can then be removed and replaced with a new magnetic switch 5 for testing, which is convenient and quick. In addition, the base 2 has multiple mounting holes 24. The sockets 23, the load module 21, and the indicator light 6 are all fixedly installed on the base 2 through the mounting holes 24. This improves the convenience of installation and provides better expandability. In addition, the four corners of the lower surface of the base 2 are fixedly installed with feet 25, which can support the base 2. In addition, it also includes a cooling fan. The air outlet of the cooling fan is directed towards the housing 41, the electromagnet 4, and the magnetic switch 5. When the cooling fan is working, it blows air onto the housing 41 and the magnetic switch 5, which can dissipate heat and cool down the electromagnet 4 and the magnetic switch 5, thereby improving the stability of the test.

[0027] The implementation principle of the magnetic switch life testing device of this utility model is as follows: The tester inserts the magnetic switch 5 into the insertion slot of the outer shell 41 and inserts the plug of the magnetic switch 5 into the socket 23 of the base 2. The power supply 1 supplies power to the electromagnet 4 through the controller 3, thereby causing the electromagnet 4 to generate a magnetic field, which in turn causes the magnetic switch 5 to close, the indicator light 6 to light up, and the counter 22 to count once. By continuously switching the power on and off to the electromagnet 4, the magnetic switch 5 is controlled to continuously close and open until the life of the magnetic switch 5 is obtained. Multiple magnetic switches 5 can be tested at the same time, and the test time is fast and the test efficiency is higher. The magnetic switch 5 is qualified when its lifespan reaches 100,000 times.
