Description

Audio connector

The present invention relates to a connector, and more particularly to an audio connector capable of transmitting an audio signal.

Generally, for example, a sound source generating device such as an audio host, in order to transmit the sound source to a receiving device such as a speaker or the like, an audio jack is usually installed on the sound source generating device and the receiving device, and then connected by a connecting wire having an audio connector. Conventional audio connectors are typically designed with a terminal unit mounted inside an outer tube holder. The terminal unit generally has a negative conductive seat connected to the negative pole of the sound source connecting line, a positive conductive seat electrically connected to the positive electrode of the sound source connecting line, and an insulation disposed between the negative conductive seat and the positive conductive seat. seat. Wherein, the negative conductive seat has a rod-like structure, and some are an annular grounding piece surrounding the positive conductive seat.

However, it is known to those skilled in the art of audio connectors that when a general audio connector is used, when a current passes through the negative conductive seat of the audio connector, if the negative conductive seat is in a ring structure, the moving magnetic field intersects with the negative conductive seat of the metal conductor. Therefore, a circulating current is generated inside the negative electrode conductive seat, and the circulating current generated in the conductor is generally called an eddy current (Eddy). Current), since the eddy current will cause noise and affect the transmission quality and sound quality of the audio, it is known that the audio connector of the negative electrode conductive seat having a ring structure generates more noise when used.

However, there are many factors affecting the quality of sound quality transmission. In addition to the eddy current will cause noise, the larger the transmission area of the negative conductive seat, the better the sound quality transmission quality. Conversely, the smaller the transmission area of the negative conductive seat, the sound quality. The worse the transmission quality will be. However, although the audio connector of the negative electrode conductive seat having the rod-like structure can avoid the generation of eddy current, the transmission area of the negative electrode conductive seat of the rod-shaped structure is small, so that a better transmission quality cannot be produced.

The purpose of the present invention is to provide an audio connector that can further improve the quality of sound quality transmission.

The audio connector of the present invention can be connected to a sound source connecting wire, and includes an outer cylinder base, and a terminal unit mounted on the outer cylinder base, the terminal unit includes a positive conductive seat connected to the sound source connecting line, and a a negative electrode conductive seat connected to the sound source connecting wire, and an insulating seat connecting the positive electrode conductive seat and the negative electrode conductive seat to the ground, the positive conductive seat has a plug portion, and the negative conductive seat has a surrounding a grounding ring portion of the shank portion, a negative electrode connecting portion connected to the sound source connecting wire, and a through-groove extending along the longitudinal direction of the negative electrode conductive seat and penetrating the grounding ring portion and the negative electrode connecting portion The grounding ring portion has a plurality of grounding pieces spaced apart and surrounding the spigot portion.

The beneficial effect of the present invention is that the through-groove through the ground ring portion and the negative electrode connecting portion can eliminate the eddy current. In addition, the sound source transmission area of the grounding strips will not be reduced to further improve the sound quality transmission quality.
