Description

headphone socket

Technical field:

The utility model relates to the technical field of sockets, in particular to an earphone socket.

Background technique:

Intel released the AC97 (Audio Codec97) audio standard in 1996, which is an important production standard for headphone jacks in various electronic accessories manufacturers in recent years. Satisfy people's pursuit of sound quality. Therefore, Intel Corporation introduced a new audio standard - HD (High Definition Audio) audio standard, which has regulations on how to reduce noise in various aspects. For example, when using the audio socket on the front panel of the computer, inserting the plug will cause certain noise interference to the audio output from the audio socket on the main board on the rear panel of the computer, which is not allowed in the HD standard. Therefore, the HD standard stipulates that when using the audio socket on the front panel, the audio output on the rear panel of the computer is shielded through the line on the headphone socket. When the plug is inserted into the headphone socket, the two jumper heads on the headphone socket are electrically connected. , the signal receiving pin on the control chip that is electrically connected to the headphone socket senses that the headphone socket currently in use is an audio socket on the front panel, and outputs an audio signal to the port of the audio socket on the front panel, while shielding the back of the computer On the other hand, when using the headphone jack on the rear panel of the computer, shield the audio jack on the front panel of the computer.

In order to solve the above problems, various electronic accessories manufacturers have designed corresponding earphone jacks. The existing solution is to fix a metal shrapnel and a metal fixing piece in the plastic base of the earphone jack, and an insulating plastic piece is fixed at the end of the metal shrapnel. , the plastic sheet is located between the two wires and the earphone insertion hole, when the plug is inserted, the plug presses the plastic sheet to one side of the fixed sheet, so that the two jumpers are in contact and electrically connected. Although this design can solve the above-mentioned problems, the insulating plastic sheet fixed on the end of the metal spring is easy to fall off during use, and it needs to increase the process of installing the insulating film, which is troublesome to manufacture and thus increases the production cost.

Utility model content:

The purpose of the utility model is to provide an easy-to-manufacture earphone jack aiming at the deficiencies in the prior art, which not only conforms to the new HD standard, but also is compatible with the old AC97 standard.

Wherein, the long leg is extended with an extension part for conducting with the shell.

Wherein, a raised portion is formed on the short leg.

Wherein, the shrapnel is a bent shrapnel, and the flat piece is provided with a bump cooperating with the shrapnel.

Wherein, an elastic part is extended on the static piece, and a convex point cooperating with the elastic part is formed on the moving piece.

The beneficial effects of the utility model are:

The connecting pin of the utility model includes long pin, short pin, shrapnel, flat piece, moving piece, static piece, wherein, the long pin used for audio grounding is installed on the bottom of the base, and it conducts with the casing; The short pin is installed on On the top of the base, the shrapnel and the flat piece are installed on the right side of the base. The shrapnel and the flat piece form the first switch, and the shrapnel and the flat piece are connected. When the plug is inserted into the audio jack of the base, the first switch is turned on, that is The elastic piece is separated from the flat piece, so that the utility model is suitable for the old AC97 standard; the moving piece and the static piece are installed on the left side of the base, and the moving piece and the static piece form a second switch, and the moving piece is separated from the static piece, When the plug is inserted into the audio jack of the base, the second switch is turned on, that is, the moving piece and the static piece are turned on, so that the utility model conforms to the new HD standard; at the same time, the inner wall of the audio jack is formed with a plastic shrapnel, It is used to replace the plastic sheet of the existing earphone socket. The plastic elastic sheet is located between the first switch and the second switch. The plastic elastic sheet and the base are integrally formed, not easy to fall off, and the manufacturing process is simplified. Therefore, the utility model not only conforms to the new HD standard, but also can be compatible with the old AC97 standard, and is convenient to use, has a wide application range, and is easy to manufacture.
