Description

Technical Field

[0001] The utility model relates to the technical field of a power-off switch test bench, in particular to a power-off switch test bench with an insulation protection effect. Background Art

[0002] The word switch is interpreted as opening and closing. It also refers to an electronic component that can open a circuit, interrupt current or make it flow to other circuits. The most common switch is an electromechanical device operated by humans, which has one or more electronic contacts. The "closed" of the contact means that the electronic contact is conductive, allowing current to flow through, and the "open" of the switch means that the electronic contact is not conductive, forming an open circuit, and current is not allowed to flow through. According to the purpose, it is classified as follows: wave switch, band switch, record and play switch, power switch, pre-selection switch, limit switch, control switch, transfer switch, isolating switch, travel switch, wall switch, intelligent fire protection switch, etc. Therefore, a power-off switch test bench with insulation protection effect is needed.

[0003] According to the description of a switch on-off power test bench disclosed on the patent website (authorization announcement number: CN 216622613U), "The utility model belongs to the field of switch technology, and is particularly a switch on-off power test bench, including a test bench, the bottom of which is evenly provided with telescopic columns, one end of which is slidably connected with a telescopic sleeve, one end of which is provided with a chassis, and the surface of the test bench is evenly provided with material troughs. The switch on-off power test bench fixes the switch in the material trough by a first clamp, and then drives the connecting wire to contact the two ends of the switch through a threaded rod, replacing the previous manual hand-held connecting wire test method. It has a simple structure and is easy to operate, which not only saves manpower, but also improves the safety of the device and avoids manual electric shock. There are two material troughs, which can test two switches at the same time, saving test time and improving test efficiency. The rubber pads on the surfaces of the first clamp and the second clamp can play an insulating role, increase the protection effect, improve the performance of the device, and extend the service life of the device."

[0004] In view of the above description, the applicant believes that the following problems exist: when the device is in use, the device is placed in a suitable position, and then the test bench is adjusted to a suitable height by means of the telescopic column and the telescopic sleeve, the telescopic sleeve and the telescopic column are connected together by fixing bolts, and then the switch to be tested is placed in the material trough, and then the first clamp is pushed by the electric telescopic rod to clamp and fix the switch, and then the threaded rod is driven by the motor to rotate so that the connecting wires on the surface of the slide are moved to one end of the switch to contact it for testing. When the device is fixed, it is necessary to use multiple electric telescopic rods to push the first clamp to fix it, which will result in a waste of resources. At the same time, the device is exposed to the outside world, and there is a high possibility of accidental touch by people, and the dust contained in the air may affect the test.
