A portable detection device for mechanical switch drop hammer impact test

Abstract

The invention relates to a portable detection device for a mechanical switch drop hammer impact test, which includes a detection circuit board, an output display circuit and a button battery that provides power for the detection circuit board; the detection circuit board includes a battery voltage monitoring circuit for monitoring the battery voltage, a sampling resistor 1. Monostable pulse generation circuit; the positive pole of the battery and one end of the sampling resistor are respectively connected to the two terminals of the mechanical switch of the test piece. When the mechanical shock triggers the conduction of the mechanical switch under test, the sampling resistor generates a pulse signal and transmits it to the monostable The pulse generation circuit, the monostable pulse generation circuit outputs a monostable pulse to the output display circuit, and the output display circuit lights up for a set time and then goes out. The detection device of the present invention can realize the drop hammer impact test detection of the mechanical trigger switch without external equipment, does not need stabilized power supply, oscilloscope, multimeter and other equipment, and is easy to carry and easy to operate, which is beneficial to reduce costs and mass production requirements.

Description

technical field [0001] The invention relates to a detection technology of a mechanical switch drop hammer impact test. Background technique [0002] In a mechatronic product or system, the mechanical trigger switch is an important component, and the system often has strict assessment requirements for the malfunction caused by mechanical impact. Different from general electronic products, the detection of the mechanical impact test of the product containing the trigger switch is real-time, that is, during the process of the drop weight impact test, the detection system must be able to accurately judge the performance of the trigger switch and output the detection results. [0003] However, the existing detection systems often require equipment such as regulated power supplies, oscilloscopes, and multimeters, and more equipment is required for simultaneous detection of multiple products, which makes the detection complex and is not conducive to mass production of the tested pr...
