Description

Technical Field

[0001] The utility model relates to the technical field of earphone sockets, in particular to an earphone socket connector with a detection structure. Background Art

[0002] Headphone jacks are mainly used in stereoscopic mobile phones, CD players, cordless phones, MP3 players, digital laptops, DVDs, digital cameras, and many audio and video electronic products are equipped with headphone jacks to provide audio output interfaces. The headphone plugs that match them are stepped cylindrical. Each step, as a different electrode, needs to form electrical contact with different conductive sheets in the headphone jack to achieve the purpose of connecting the left channel, right channel, microphone, and grounding.

[0003] In the use of some existing headphone sockets, when the headphone is inserted into the headphone socket, these headphone sockets are simply connected to the headphone plug. Although the detection switch terminal sends a signal that the headphone is inserted during use, the various terminals in the headphone socket are not in a stable state of contact with the corresponding electrodes in the headphone plug at this time, and the full insertion detection function is not satisfied, and some noise will be generated at this time; when the headphone plug is unplugged, the detection switch terminal has not yet detected the unplugging operation, and the various terminals in the headphone socket are disconnected from the corresponding electrodes in the headphone plug. The detection switch terminal cannot achieve the function of early detection, and at the same time, some noise will be generated. Usually, a delay circuit is added to the line to achieve the effect of eliminating the noise, but the structure of these circuits is relatively complex and the manufacturing cost is relatively high.
