Description

Audio socket connector

Technical field

The utility model provides a kind of audio socket connector, refers in particular to a kind of can combining with the voice plug to reach the cab over type audio socket connector of transferring voice signal function.

Background technology

Have the audio socket connector that can produce the message effect and be widely used in the audiovisual acoustic product, its major function is to provide the transmission of voice signal between two systems.In recent years, along with the appearance of various legerity type electronic digit products, as mobile phone, PDA, MP3, with the development of electronic digit product such as notebook computer, the application of audio socket connector on these products is more capable important.Each electronic product all has its audio socket connector that exclusively is suitable for to occur, and such relevant product design please refer to U.S. Pat 6,478,629, US4, cases such as 659, No. 167.

Existing audio-frequency electric connector design is with through hole weldering or two kinds of methods of surface adhesion electric connector to be fixed on the circuit board mostly, when using the through hole soldering method, because this method is to weld in the welding hole of electric connector with corresponding setting on the terminal supportor insertion circuit board, its stationarity is not more for stable, and the shared circuit board space of using is also bigger, is more unaccommodated for the electronic digit product of lightweight more and more; And on the surface adhesion method, because product specification design now also becomes more and more tiny, on bonding for connector and circuit board, certainly will also increase the degree of difficulty on the adhesive technology, impel product design also must considered, be easy to the bonding electric connector that does not have influence on product efficacy again to improve out for this respect.

In addition, existing audio connector in design, most glue core total length all maintains between the 13-14mm, this is inappropriate for all quite limited legerity type electronic product of inner usage space and circuit board space, and long structure also can increase burden for the production and the manufacturing cost of product; And since present electronic product on external form and the function also all towards in conjunction with multi-functional and lightly develop in the trend of one, the design of this elongated also can limit the flexibility of product and the effectiveness on the function, so also certainly will will revise for the specification on the product, in the hope of product usefulness being reached optimization.

Moreover, to the product under using in varying environment, its contact engaging and separating force for audio connector has different requirements, particularly being needs more in the mobile device to consider that it is the required contact engaging and separating force size of using in different application scenarios, and in existing SMT type terminal structure, be each terminal institute mean allocation to the required contact engaging and separating force of combination hub, contact engaging and separating force such as need increase or reduce, then terminal structure just must redesign mould or select material, is unfavorable for so too reducing cost.

Simultaneously, existing audio socket is because single diameter through after repeatedly plugging, is all done touching back and forth with each terminal because of the audio jack body of rod, and terminal produces the bad phenomenon of elasticity because of excessive friction easily.

The utility model content
