Waterproof headphone sockets are currently used in a wide range of applications, such as CD players, mobile phone equipment, DVDs, and digital cameras. Do you all know the precautions for the use of the headphone socket? Although many businesses now purchase the headphone socket with some manuals and the like, the precautions mentioned in it are not comprehensive. I remember that I also told you about the structure, purpose and classification of the patch headphone socket before. The editor asked the professional technicians to understand the instructions for the use of the headphone socket, and summarized the nine precautions for the use of the headphone socket, in detail The content is as follows. Nine precautions for the use of waterproof headphone socket: 　　

　　The first point of attention　

　　Do not touch the headphone socket with wet hands in daily use, otherwise it may cause electric shock and other accidents to the human body. At this point, great attention is needed.　

　　The second point of attention　　

　　When the waterproof headphone socket is not used, it is recommended to cover the dustproof cover, otherwise the coating on the surface of the headphone socket will oxidize after being in contact with the air for a long time, causing the headphone socket to cause some poor contact with the plug.　　

　　The third point of attention　　

　　At present, the waterproof headphone socket has 2.5MM and 3.5MM specifications, which should be selected according to the requirements of the equipment when using it, because the requirements for the use of headphone socket equipment of different specifications are also different. Some equipment does not Not compatible with the use of 2.5MM headphone jack. Otherwise, it will be easier to damage the earphone socket if it is used forcibly, so you need to pay attention to this point in use.

　　Fourth precautions　

　　The insulation resistance of the waterproof headphone socket must generally be greater than or equal to 100MΩ. The insulation resistance refers to the resistance between the conductors of the waterproof headphone socket that are not in contact. If it is less than 100MΩ, the resistance between the conductors will not be able to load the normal current. It may damage the waterproof headphone socket. Waterproof headphone socket supply　

　　The fifth point of attention　　

　　If abnormal sound or burning smell is found in the earphone socket, the power supply should be cut off immediately for maintenance. Avoid some safety accidents and so on.

　　The sixth point of attention　　

　　Do not exceed the specified maximum rated current when the waterproof earphone socket is working. If the maximum rated current is exceeded, some components inside the earphone socket will accelerate the aging phenomenon, and at least it may cause silent or other failures during use. In severe cases, the waterproof headphone socket may be damaged.　

　　The seventh point of attention　　

　　When the line is connected, the resistance between the two contact conductors of the waterproof earphone socket is called the contact resistance. Generally, the contact resistance of the waterproof earphone socket should not exceed 0.03Ω.　

　　The eighth point of attention　　

　　The electrical strength of the waterproof headphone socket should generally be greater than AC500V. Its electrical strength is also called withstand voltage, which refers to the voltage that the conductors contacting the headphone socket can withstand. If the withstand voltage is less than AC500V, the conductor between the earphone sockets will not be able to load when the device is operating at a relatively large voltage, which may lead to the possibility of burnout, so pay more attention to this point.

　　The ninth point of attention　

　　In the daily use of the headphone socket, do not use too much force when inserting the plug into the waterproof headphone socket, otherwise it may damage the transmission chip inside the waterproof headphone socket.
