The headphone Jack female is a functional electronic switch that is a standard part. When in use, gently press the switch button to turn the switch on, and when you release your hand, the switch will be turned off. The internal structure of the headphone socket is a quasi-metallic shrapnel that is forced to spring to complete the opening and closing. Headphone sockets are widely used in electrical appliances due to their small contact resistance, crisp and clear touch when pressed, and complete height specifications.
Headphone jack socket interface specifications:
The headphone jack female is an interface used to connect headphones and audio source devices (such as mobile phones, computers, etc.). It is usually located on the side or bottom of the audio source device and has different sizes and specifications according to different standards. Common standards include 3.5mm, 6.3mm. According to the different types of pins, they can be divided into straight pins, curved pins, wired pins, etc.
Headphone jack type classification:
1. The phone jack structure types are divided into: plastic shell type, frame type, current limiting type, DC fast type, excitation type and leakage protection type.
2. The number of poles of the headphone socket can be divided into: single pole, two pole and three pole.
3. The full breaking time of the headphone socket: the normal and fast types act before the tripping mechanism, and the tripping time is within 0.02 seconds.
4. The headphone socket protection forms are divided into: composite release, thermal release type and no release type.
Headphone jack structure:
Headphone sockets are generally composed of multi-contact and socket structures, which mainly include headphone plugs, sockets and conductive sheets. First, the headphone socket is provided with a central plug for the headphone plug, and then there is an auxiliary plug on both sides of the plug, and more than two sets of metal sheets are provided on both sides of the auxiliary plug. However, there is a circular insertion hole in the center of the headphone socket, which serves as the connecting part for the headphone plug plug. The conductive sheet of the earphone socket also has a curved contact portion, and the contact portion can contact the metal sheets on both sides of the auxiliary plug to form an effective conductive contact and provide an independent transmission. However, at the same time, auxiliary insertion holes are also provided on both sides of the headphone socket, which are arranged relative to the auxiliary plug posts. In addition, two opposite conductive sheets are provided inside the auxiliary headphone plug insertion holes.
Common faults of headphone jack sockets:
1. The headphone plug interface is not operated in a standard manner, causing it to become loose, resulting in noise during sound transmission.
2. The headphone plug is exposed to the air for a long time, causing the surface coating to oxidize after contact with the air, resulting in poor headphone contact and affecting the use effect.
3. Usually when using headphones, during the plugging and unplugging process, the internal welding of the headphone plug and the headphone socket will become loose over time, causing the headphone plug and the headphone socket to become loose.
