Abstract

The invention provides an AC / DC driving detection device. The device comprises a voltage-stabilized power supply circuit, a waveform generator, a signal amplification circuit, a signal receiving module, and a detected circuit. The voltage-stabilized power supply circuit is respectively connected with the waveform generator, the signal amplification circuit, and the signal receiving module. The detected circuit comprises a signal receiving end and a signal output end. The signal receiving end is connected with the waveform generator. The signal output end is connected with the signal amplification circuit. And the signal amplification circuit is connected with the signal receiving module. By applying the technical scheme, detection of compatible AC / DC driving can be realized, and voltage support of up to tens of volts is not needed, so that the safety of personnel implementing the detection process is guaranteed.

Description

Technical field [0001] The invention relates to the field of circuit detection, in particular to an AC and DC drive detection device. Background technique [0002] In many electronic products, the contacts between the drive circuit board and the input power supply part, such as pin pins, plugs, etc., need to be connected in various ways; for example, the input line needs to be riveted or welded, which is required in this input loop Determine whether the contact is good, so as to proceed to the next assembly process; for example, using pin riveting, and riveting will have the risk of poor contact, which requires a detection device to detect whether the interfaces of these electronic products are properly wired. However, the detection equipment of the prior art not only does not have the function of being compatible with AC and DC drive detection at the same time, but the voltage required for detection is as high as several tens of volts, which poses no small threat to the life saf...
