M248071 V. Creation Instructions (1) [Technical Field to which the New Type belongs] Disk-ΐϊϊ: It is an audio socket connector, especially a finger plug; a flat head that combines to achieve the function of transmitting voice signals. [Previous technology] Audio effects produced in the mouth The audio socket connector is used in the audiovisual St. Its main function is to provide the two systems. "In recent years, with the development of various lightweight electronic digital products such as Talk, PDA, MP3, and digital production of notebook computers, audio socket connection An electronic product on these products has its exclusive applicable audio plug. For the design of such products, please refer to the US patents US 6 '478, 629, US 4, 659, 1 67, etc. Existing Most of the audio electrical connector designs are through-hole soldering or table to fix the electrical connector to the circuit board. When using the ^ method ', because the method is to insert the electrical connector into the circuit corresponding to the terminal pins Soldering in a soldering hole has less fixability, which occupies more space on the circuit board. It is not suitable for digital products that are getting lighter and lighter. ^ Adhesion side, go up, the product specification design has become more and more small, the connection of the connector board, it is bound to increase the difficult production of dry connection technology, ^ design must also consider this aspect In order to improve = easy to not affect the product's electrical connector. In addition, the existing audio connectors in the design, most of the energy-saving audio products such as Lv Wuxin's electronic applications such as the seat connection surface adhesive holes Welding the phase on the square board, and the electronics are glued to the product due to the current and the circuit. The total core is M248071 V. Creation instructions (2) The length is maintained between 13-14mm, which is very limited for internal use * Board space For lightweight electronic products, the structure of the stomach and the circuit 2 is a, which will increase the production and manufacturing costs of the product: Due to the current appearance and function of electronic products, g can be lighter and lighter than The long-term trend of development is integrated. This long = t multi-function has increased the flexibility and functional effectiveness of the product: 2: The system must also be modified in order to achieve the best performance of the product. Do not The production of 0 under environmental applications has different requirements for the insertion and extraction force of beans. 'Special; make special arrangements; ^ The test J is used in different applications. === Each school must be distributed and inserted. If the pull force is required, you need to redesign the mold or select materials, substructures, etc. The same is not conducive to lowering the pull rate:: Li: The single-diameter frequency socket is repeatedly inserted after multiple insertions. The rod body touches each terminal back and forth, and the terminal is prone to produce valleys with poor elasticity due to excessive friction. [Content] This book is designed to improve the lack of existing audio connectors. The creation is to provide a plug length design with a rubber core length and improved terminal contact folds, in order to shorten the structure, the structure of the electrical connector is arranged in the space for the audio electrical connector and achieve the enhancement of product functions;卩 Save the internal integration of the product into one. This effect makes it compatible with multifunctional products
