Abstract

The utility model provides a multiple headset jack switching socket, which belongs to the extension of an audio frequency socket. The socket comprises a stereo plug (1) and more than one stereo jack (2), wherein the stereo plug (1) and the stereo jack (2) are integrally connected with each other through an insulation body (3); each sound channel electrode of the stereo plug is respectively connected with the sound channel contact pieces corresponding to each stereo jack (2) through a conducting wire; and an earth pole is connected with the public ground wire of the stereo jack (2). By utilizing the integration of the insulation body, the utility model ensures that one jack is extended to be a plurality of jacks and respectively connected to various audio output loads, the designing patterns are rich and colorful; and the benefits for product stability and added value promotion are remarkable.

Description

Plurality of earphone jack conversion socket

Technical field

The utility model relates to a kind of audio socket expansion connector, is meant a kind of structure-integrated, plurality of earphone jack conversion socket that a socket can be extended to a plurality of sockets especially.

Background technology

At present, the mobile phone of stereo set such as radio-cassette player, CD player, mp3 player and band mp3, earphone accessory power outlet manufacturer only designs the stereo socket of 3.5 millimeters or 2.5 millimeters, can only be used for a set of headphones, during use, a plurality of if necessary sockets (for example: insert two secondary or two secondary above earphones simultaneously, during and AUDIO OUT or SPEAKER output simultaneously) multi-functional use form, then must be attached to different audio outputs respectively by each socket with the socket of a plurality of single socket types simultaneously and close use.

Yet, the socket of each single socket type all has its fixing basic structural feature (shape of number of terminals, terminal arrangement mode, insulating base, the thickness at each position of insulating base ... Deng), the socket of a plurality of single socket types also closes when using, it not only has the setting of many terminals and insulating base thickness at interval to be all repetition, and cause the waste of element production cost and volumetric spaces, complexity when unnecessary terminal has also increased the associated circuit board layout designs simultaneously is unfavorable for that electronic circuit dwindles day by day, the trend of precise treatment.

Summary of the invention

Technical problem to be solved in the utility model is: because common audio socket structure has above-mentioned shortcoming, the inventor is improved at those shortcomings, a kind of plurality of earphone jack conversion socket is provided, can simplifies the jack design of stereo set, help dwindling its volume; Thereby realize that a socket is extended to a plurality of sockets and is attached to different audio frequency output loadings respectively.

The technical scheme that the utility model is dealt with problems is such, a kind of plurality of earphone jack conversion socket, comprise stereo plug and more than one stereo socket, connect by an insulating body is whole between stereo plug and each the stereo socket, each sound channel electrode of stereo plug links to each other by the corresponding sound channel contact of lead and each stereo socket respectively, and the common ground of earth polar and stereo socket is connected.

In order to satisfy consumers in general's demand, the shape of insulating body of the present utility model can be done styles such as rectangularity, triangular prism shaped, quartzy sphere, cartoon toy; Stereo socket on the insulating body is selected by linear array, delta arrangement and multidirectional Boulez according to concrete shape.

The utility model is because only need stereo set having a socket, change by the plurality of earphone jack, just can satisfy a plurality of earphones of many humans and appreciate the music of listening to grace, the socket that need on existing stereo set, not be equipped with a plurality of single socket types, associated circuit board layout designs on the simplified apparatus relatively, can effectively reduce the audiophile and buy the cost of stereo set, so make things convenient for economical.This kind audio sockets structure of the present utility model, it utilizes the integration of insulating body, common design, and the moulding style is rich and varied, to the stability of product and promote surcharge and also have obviously and benefit.
