First, don't wet your hands during daily use. Headphone socket, otherwise it will cause electric shock and other accidents. At this point, you need to pay great attention.

Second, when you don't use headphone jack, it is recommended to put dust If the cover is covered, the plating on the surface of the earphone socket may oxidize after being touched by the air for a long time, so that the earphone socket may cause some contact with the plug.

Third, the current specifications of the earphone socket are 2.5MM and 3.5MM, etc., should be selected according to the requirements of the equipment when using, because the requirements of different specifications of the earphone socket device will be different, some The device is not compatible with the 2.5MM specification headphone jack. Otherwise, it is easier to damage the earphone socket, so it is necessary to pay attention to this.

Fourth, the insulation resistance of the earphone socket must be greater than or equal to 100MΩ. The insulation resistance refers to the non-contact Headphone socket The resistance between the conductors, such as less than 100 MΩ, will not load the normal current between the conductors, which may damage the headphone jack.

Fifth, if you find headphone jack, the sound is abnormal, or there is burning In the case of odor, etc., the power should be turned off immediately for maintenance. Avoid some safety incidents, etc.

Sixth, do not exceed the specified maximum rated current when working in the earphone socket. If the maximum rated current is exceeded, it will make Headphone Sockets Some internal components speed up aging, which can lead to silent or other faults during use, which can seriously damage their headphone jacks.

Seventh, when the line is connected, the resistance between the two contact conductors of the earphone socket is called contact resistance, generally Headphone socket The contact resistance should not exceed 0.03Ω.

Eighth, the electrical strength of the earphone socket should generally be greater than AC 500V, and its electrical strength is also called the withstand voltage refers to the voltage that the conductor can withstand when the earphone socket contacts. If the withstand voltage is less than AC 500V, Headphone socket when the device is running with a relatively large voltage. The conductor between will not be able to withstand the load, which may result in burning, so pay more attention to this point.

Ninth, in the daily use of the earphone socket, insert the speaker socket into the plug > Do not insert or pull the force too much, otherwise it may damage the transfer chip inside the headphone jack.

The above is Dongguan getwell Electronics introduces the nine precautions for using the headset socket. Everyone should also have a comprehensive understanding of the precautions for using the headset socket, and then finally say the next two in Headphone socket Two points of attention when soldering, one point is that the headphone socket is generally sensitive to heat when soldering. Do not touch the head of the soldering iron for a long time. On the feet. The second point is that the general power of the soldering iron should not exceed 30W. In this case, the filler solder should be used. The solder can remove the template of the circuit board and the oxide film on the wire when the earphone socket is soldered.
