Earphone connector

Abstract

The invention relates to the technical field of earphone plug-in mounting, and discloses an earphone connector. The earphone connector comprises a plug and a socket, the plug comprises an insulating column, the insulating column is sequentially provided with a first stage, a second stage, a third stage and a fourth stage which are insulated from one another in the length direction, the insulating column is provided with an annular boss, and the annular boss is located on the side, away from the third stage, of the fourth stage; a fifth stage is arranged on the annular boss; a detection terminal, a microphone terminal, a left channel terminal, a right channel terminal and a grounding terminal are arranged in the socket; the plug is inserted into the socket, the first stage is connected to the detection terminal, and the detection terminal is used for judging whether the plug is inserted or not; the second stage is connected to the microphone terminal; the third stage is connected to the left channel terminal; the fourth stage is connected to the right channel terminal; and the fifth stage is connected to a grounding terminal. The earphone connector is grounded, the plug can be applied to a socket of a four-stage plug and a socket of a five-stage plug, and the universality of the plug is improved.

Description

technical field [0001] The invention relates to the technical field of earphone insertion, in particular to an earphone connector. Background technique [0002] At present, in work and life, earphones are widely used in electronic equipment products. The type of conventional headphone plug is a four-level plug. The four-level plug includes the first level, the second level, the third level and the fourth level. Among them, the first level is used to connect the detection terminal, and the detection terminal detects whether the earphone is inserted. , the second level is used to connect the microphone terminal, the third level and the fourth level are used to connect the left channel terminal and the right channel terminal, but the four level plug is not highly preventive of short circuit and other situations, and it is prone to short circuit and conductive phenomenon. Therefore, a five-level plug is also designed in the prior art, that is, the ring-mounted metal sheet of th...

The type of conventional headphone plug is a four-level plug. The four-level plug includes the first level, the second level, the third level and the fourth level. Among them, the first level is used to connect the detection terminal, and the detection terminal detects whether the earphone is inserted. , the second level is used to connect the microphone terminal, the third level and the fourth level are used to connect the left channel terminal and the right channel terminal, but the level 4 plug is not well protected against short circuit and other situations, and it is prone to short circuit and conductive phenomenon

Therefore, a five-level plug is also designed in the prior art, that is, the ring-mounted metal sheet of the fourth level is changed to two levels, and the fifth level is used to connect the grounding terminal. However, the five-level plug with this structure cannot be applied to The socket of the four-level plug has poor versatility
