At the same time, the quality requirements for switches are also getting higher and higher, especially in the case of multiple ports, high-power loads, and long-term high-temperature environments, the quality requirements are even higher. Once the device is installed, if the switch has an aging failure, it will cause the device to malfunction, and the function of device operation and supervision will be lost. Therefore, from the perspective of the overall quality and performance of the product, the aging test of the switch becomes increasingly important.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Please refer to Figure 1-2, the present utility model provides a technical solution: a switch aging fixture, which includes a fixture frame 1. On the other side of the upper end of the fixture frame 1, a switch main body 11 is placed. On one side of the fixture frame 1, a bracket 12 is welded. At the rear side of the bracket 12, a servo motor 13 is fixedly installed. At the output end of the servo motor 13, a transmission rod 14 is installed. In the middle of the transmission rod 14, a fixed block 15 is detachably installed. On one side of the upper end of the fixture frame 1, a first straight rod 2 and a second straight rod 21 are movably installed. At the upper end of the second straight rod 21, a baffle 23 is fixedly installed. On one side of the upper end of the fixture frame 1, an infrared pair counter 3 is detachably installed. The length of the first straight rod 2 is the same as that of the second straight rod 21, which is convenient for ensuring the intermittent movement effect of the first straight rod 2 and the second straight rod 21, so that the switch can be opened or closed reciprocally. The fixed block 15 is arranged on one side of the first straight rod 2 and the second straight rod 21, and the fixed block 15 corresponds to the first straight rod 2 and the second straight rod 21, which is convenient for intermittently pushing the first straight rod 2 and the second straight rod 21 through the setting of the fixed block 15. The signal output end of the infrared pair counter 3 is connected to the signal input end of the PLC controller 4, and the signal output end of the PLC controller 4 is connected to the signal input end of the display screen 5, which is convenient for displaying the aging times of the switch during the test, so as to facilitate the staff to record.

[0025] On the outer side walls of both the first straight rod 2 and the second straight rod 21, a spring 22 is sleeved, and the other end of the spring 22 is fixedly connected to the fixture frame 1, which is convenient for driving the first straight rod 2 and the second straight rod 21 to rebound and reset through the setting of the spring 22.

[0026] The infrared pair counter 3 is arranged on both sides of the baffle 23, and on one side of the infrared pair counter 3, a PLC controller 4 and a display screen 5 are arranged, which is convenient for blocking the infrared rays of the infrared pair counter 3 and facilitating automatic counting.

[0027] During use, first place the switch main body 11 to be detected on the fixture frame 1, and then turn on the servo motor 13. The servo motor 13 drives the transmission rod 14 to rotate reciprocally by 60 degrees, so that the fixed block 15 on the transmission rod 14 intermittently pushes the first straight rod 2 and the second straight rod 21, further enabling the first straight rod 2 and the second straight rod 21 to reciprocally open and close the switch, thereby detecting the aging times of the switch during use. At the same time, every time the second straight rod 21 moves to the left, the baffle 23 on the second straight rod 21 will separate from the infrared pair counter 3. Each time it passes through, it is counted once. Then, the signal is transmitted to the PLC controller 4 through the infrared pair counter 3, and the PLC controller 4 transmits the data to the display screen 5, so as to display the detection times of the switch on the display screen 5, facilitating the staff to record the aging times of the switch of the switch main body 11.
