Microphone connecting device for flip type portable telephone

一种将装在翻盖上的麦克风电连接于手机主体中音频电路的装置。当翻盖受到过大的力时该翻盖可与手机主体脱开。铰接装置包括两个铰接微组件，各个微组件包括：铰接支架；铰接轴，其一端具有凸出部，而其另一具有轴，装在铰接支架内；导电装置，紧紧地压入沿铰接轴的轴线形成通孔内；凸轮式铰接件，具有在一侧交替形成的相对凸部和相对凹槽，该凸出部和凹槽嵌合铰接轴，该凸轮式铰接件还具有沿铰接轴的轴线形成的通孔；铰接盖，用于覆盖铰接支架的一个端部，该铰接盖具有沿铰接轴的轴线形成的通孔；盘簧，插放在凸轮式铰接件和铰接盖之间，以便形成弹力，翻盖包括：第一连接端子，该端子具有平表面、曲表面和弹力部分，其中该弹力部分保持与导电装置的电接触；装在翻盖上的麦克风。 A device for electrically connecting a microphone mounted on a flit cover to an audio circuit of a telephone body. The flip cover is detachable from the telephone body when an excessive force is applied thereto. A hinge apparatus includes two hinge modules each including a hinge housing, a hinge shaft having a protrusion at an end and a shaft at another end, being assembled into the hinge housing; conductive means fixedly pressed into a through hole formed along an axis of the hinge shaft; a cam hinge having opposing protrusions and opposing indents formed alternately at one side, engaging with the hinge shaft, and a through hole formed along the axis of the hinge shaft; a hinge cover mounted so as to cover an end of the hinge housing, the hinge cover having a through hole formed along the axis of the hinge shaft; and a coil spring intervening between the cam hinge and the hinge cover to provide an elastic force. The flip cover includes a first connection terminal having a plane surface, a curved surface and a tension part, wherein the tension part maintains electrical contact with the conductive means; and a microphone mounted on the flip cover.
