Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component life testing, and more specifically relates to a switch life testing device. Background Art

[0002] Switches, as important electronic components, are widely used in various electronic devices. Their reliability directly impacts the lifespan of these appliances. To improve their quality, switches must be subjected to a press test to assess their lifespan. Existing switch lifespan testing equipment typically lacks a specific counting function and can only determine the lifespan of a switch by measuring the test time. However, this cannot guarantee that the actuator switches at the same frequency during the test, leading to errors in the final test results. Therefore, a key lifespan testing device that can record the number of switch cycles is needed. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a switch life test device, which can record the number of times the switch is triggered while testing the service life of the switch, and can judge the service life of the switch based on the number of switching times.

[0004] The present invention provides a switch life test device comprising a frame, a counter, and a swing arm. The counter is mounted on the upper side of the frame, and the lower end of the swing arm is pivotally connected to the side of the frame. The swing arm is driven by an electromagnetic mechanism to periodically swing. A switch is fixedly mounted at the upper end of the swing arm, and the swing arm swings to activate or deactivate the switch. The electromagnetic mechanism is electrically connected to the counter to obtain and record the number of times the electromagnetic mechanism is actuated.

[0005] As a further improvement of the present invention, the counter includes a display screen, a pause button, and a reset button. The display screen is fixedly arranged on the upper side of the counter. The pause button and the reset button are arranged on the lower side of the display screen.

[0006] As a further improvement of the present invention, the switch is electrically connected to the external light strip, and the switch is used to control the external light strip to be turned on or off.

[0007] As a further improvement to the present invention, the swing arm includes a rotating portion and an actuator. One end of the rotating portion is pivotally embedded within the frame, while the other end is fixedly connected to the lower end of the actuator. A permanent magnet extending outward is fixedly mounted on the inner sidewall of the rotating portion. The electromagnetic mechanism includes a relay and an actuator power supply, which is connected to the relay. The relay is positioned on one side of the permanent magnet to drive the permanent magnet toward or away from the relay.

[0008] As a further improvement of the present invention, when the relay is energized, magnetism is generated, which repels the magnetic pole of the permanent magnet close to the relay, thereby driving the swing arm away from the relay.

[0009] As a further improvement of the present invention, a mounting plate and a pressing rod are further provided at the upper end of the swing arm. One side of the mounting plate is fixedly connected to the upper end of the swing arm, the mounting plate is close to the switch side, and the other side of the mounting plate is fixedly connected to the pressing rod.

[0010] As a further improvement of the present invention, the switch is a push button switch.

[0011] As a further improvement of the present invention, the switch is a hand-sweep switch.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By setting up a rack, a counter and a swing arm, the swing arm starts or closes the switch, and the counter records the number of times the swing arm swings to open or close the switch. It is not only possible to rely on the test time to judge the service life of the switch, avoiding errors caused by changes in the swing arm frequency during the test. It is also possible to record the number of times the switch is triggered while testing the service life of the switch, and to judge the service life of the switch based on the number of switches.

[0021] Specific embodiment 1: Please refer to Figure 1-Figure 5A switch life test device is provided, which includes a frame 1, a counter 2 and a swing arm 3. The counter 2 is arranged on the upper side of the frame 1, and the lower end of the swing arm 3 is rotatably connected to the side of the frame 1. The swing arm 3 is driven by an electromagnetic mechanism so that the swing arm 3 can swing periodically. A switch is fixedly provided at the upper end of the swing arm 3, and the swing arm 3 swings to start or close the switch. The electromagnetic mechanism is electrically connected to the counter 2 to obtain and record the number of executions of the electromagnetic mechanism. Among them, the counter 2 and the electromagnetic mechanism are both powered by an external power supply. It should be noted that detecting, obtaining and recording the number of executions of the electromagnetic mechanism by the counter 2 belongs to the existing conventional technical means, and its specific working principle and connection relationship will not be repeated here.

[0022] The switch is electrically connected to the external light strip, and is used to control the external light strip to be turned on or off.

[0023] The swing arm 3 includes a rotating part 31 and an executive part 32. One end of the rotating part 31 is rotatably embedded in the frame 1, and the other end is fixedly connected to the lower end of the executive part 32. A permanent magnet 33 extending outward is fixedly provided on the inner wall of the rotating part 31. In this embodiment, the electromagnetic mechanism includes a relay 34 and an executive power supply, and the executive power supply is connected to the relay 34. The relay 34 is arranged on one side of the permanent magnet 33 to drive the permanent magnet 33 toward or away from the relay 34. When the relay 34 is energized, it generates magnetism, which repels the magnetic pole of the permanent magnet 33 on the side close to the relay 34, thereby driving the swing arm 3 away from the relay 34.

[0024] The upper ends of the swing arms 3 are also provided with a mounting plate 4 and a pressing rod 5. One side of the mounting plate 4 is fixedly connected to the upper ends of the swing arms 3, and the mounting plate 4 is close to one side of the switch, and the other side of the mounting plate 4 is fixedly connected to the pressing rod 5.

[0025] like Figure 4 As shown, the counter 2 includes a display screen 21, a pause button 22, and a reset button 23. The display screen 21 is fixedly mounted on the upper side of the counter 2. The pause button 22 and the reset button 23 are located on the lower side of the display screen 21. The display screen 21 displays the current number of electromagnetic mechanism executions. The pause button 22 is used to pause the counter counting, and the reset button 23 is used to reset the number displayed on the display screen 21 to zero.

[0026] In this embodiment, the switch is either a push button switch 6 or a hand-swipe switch. It should be noted that when the test object is a push button switch 6, the pressing rod 5 of the swing arm 3 contacts the push button switch 6 to activate the push button switch 6. The swing arm 3 moves backward to its initial position and then forward to contact the push button switch 6 to deactivate the push button switch 6. When the test object is a hand-swipe switch, the swing arm 3 only needs to move forward to pass through the sensing area of ​​the hand-swipe switch.
