Problems solved by technology

[0003] However, unfortunately, in order to have better mechanical strength and stability, many "metal screws" arranged inside the power plug have caused a problem, that is, when there is current passing through the power plug, the current will cause The magnetic field causes the energy change of the electrons inside the metal atoms of the metal screw close to the current, which in turn causes the dissociation of some electrons originally bound inside the metal atoms, resulting in the flow of electrons inside the metal screw, and the flow of electrons will also generate a magnetic field , the generated magnetic field will further interfere with the stability of the current flowing through the product, so the sound quality of the audio equipment using the power plug will deteriorate, and the ultimate goal of improving sound quality cannot be fully achieved

Abstract

The present invention provides a power plug comprising a terminal seat having a conductive terminal and grounding terminal, a core wire, electrical wires connected to the conductive terminal and grounding terminal, a cover member connected to the terminal seat integrally, and a grounding device for grounding the isolated metal parts (e.g.screws).

Description

technical field [0001] The present invention relates to a power plug, in particular to a power plug capable of preventing power quality from deteriorating. Background technique [0002] In recent years, in terms of audio equipment, the influence of power supply quality on the sound quality, or the problem that the input current of the audio equipment is unstable, which will cause the sound quality to deteriorate, has attracted many attentions. At present, the power plug with better mechanical strength and stability, and its stable contact reduces the electrical impedance is used in the field of audio equipment, so that the sound quality, resolution and many other characteristics of the audio equipment are relatively improved. [0003] However, unfortunately, in order to have better mechanical strength and stability, many "metal screws" arranged inside the power plug have caused a problem, that is, when there is current passing through the power plug, the current will cause ...
