Abstract

The utility model relates to a mother socket for earphones and microphones. The front end of a plastic base, on which socket feet are positioned, is provided with a round hole. The inner side of the plastic base is provided with a slot provided with five terminals. A second supporting leg and a fifth supporting leg, positioned on the two sides, carry on the transmission of the audio signals of the left and right channels. One supporting leg positioned on the other side of the plastic base is in charge of the transmission of the audio ground signal. And one supporting leg communicated with a metal shell forms a better anti-interference electromagnetic shielding. A third supporting leg and a fourth supporting leg is positioned on the other side of the plastic base, the same side with a plastic elastic piece. When the male plug is inserted, the third and the fourth supporting leg changes from the off state to the contact state. The design applies to the jumping switch, the pull of the male plug and the resetting and the breaking of the switch of the Inter HD Audio circuit. The utility model has the advantage of a simple structure, easy manufacturing, a low cost, and a long service life time, and is not easy to be damaged.

Description

The socket female seat of earphone and microphone

Technical field

The utility model relates to a kind of socket female seat that is applied to earphone and microphone.

Background technology

INTEL releases HD Audio standard I ntel HD Audio, how this standard reduces noise in all fields all regulation, during as the audio jack on using the computer front panel, the certain noise jamming of audio producing that meeting is exported the audio jack of mainboard on the computer rear board after insertion earphone or the micropkonic male, this is unallowed in new standard.Therefore, when having stipulated the audio jack on the panel before use in this standard, export by the audio frequency that the wire jumper on the earphone socket shields on the computer rear board, when earphone or micropkonic male insertion earphone socket, two wire jumper heads on the earphone socket electrically connect, the signal that electrically connects with this earphone socket on the control chip receives pin and then senses present earphone socket in use, and, promptly shielded the earphone socket on the computer rear board to the port output audio signal of corresponding earphone socket; When the earphone socket on the use computer rear board, then shielded the earphone socket on the computer front panel, the only output of the earphone socket on the computer rear board of audio signal, Fig. 1 is its circuit theory diagrams, wherein, 15, the wire jumper on 12 earphone sockets that are respectively on the computer front and back panel, 13,14 are respectively the earphone socket on the computer front and back panel; Audio frequency input socket on computer front panel and the rear board also is like this.New standard at Intel, each computer fittings produces house and designs corresponding earphone socket one after another, the shell internal fixation that is mainly at present at earphone socket has a metal clips, the metal clips end is fixed with the sheet of an insulation, this sheet is between double bounce the end of a thread and the earphone patchhole, after earphone or micropkonic male were inserted, male was pressed to wire jumper one side with sheet, made the contact of two wire jumpers and electrically connected.Though this kind design can reach the requirement of new standard, in use, the insulation plastic cement that is fixed in the metal clips end easily comes off, and manufactures trouble, and production cost is also high.

The utility model content

The purpose of this utility model be at the deficiencies in the prior art provide a kind of simple in structure, manufacture easily, cost is low, durability is high earphone socket.

For achieving the above object, the utility model is achieved through the following technical solutions:

The socket female seat of earphone and microphone, it is the plastic cement seat by the mounting receptacle pin, and plastic cement seat front end has circular hole, and the inside of plastic cement seat has the draw-in groove that five terminals are installed, and two, five legs are distributed in both sides, carry out the left and right acoustic channels audio signal transmission; One leg is positioned at the opposite side of rubber base, is responsible for the audio ground signal transmission, and a leg and metal shell conducting, forms anti-interference preferably electromagnetic shielding; Three, four legs are distributed in the opposite side of plastic seat and plastics shell fragment in the same side, can allow three, four legs become contact condition by off-state when male is inserted, and this is designed for the jumper switch of Inter HD Audio circuit.

That this practicality has is simple in structure, manufacture easily, and cost is low, and not fragile, the advantage of long service life.

Embodiment

As Fig. 1～shown in Figure 6, the socket female seat of earphone and microphone, it is to be made of plastic cement seat 12, five terminals, a five metals shell 13 and a plastic cement lid 14, its structure distribution is: the five legs 11 rubber base groove 1 of packing into, two legs 8 groove 2 of packing into, three legs 9 groove 3 of packing into, four legs 10 groove 4 of packing into, the one leg 7 rubber base groove 5 of packing into, plastic cement bonnet 14 buckles into button bit 6, and metal shell 13 is buckled rubber base 12 then, and plastic cement bullet position 15 is positioned at three, four legs, one side, insert male 16 and can allow off-state become closure state, but three, four legs and male 16 insulation.

It only is preferred embodiment of the present utility model that above institute is chatted, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or decorate, is included in the utility model claim.

Claims

1, the socket female seat of earphone and microphone, it is characterized in that: the socket female seat of earphone and microphone, it is the plastic cement seat by the mounting receptacle pin, plastic cement seat front end has circular hole, the inside of plastic cement seat has the draw-in groove that five terminals are installed, two, five legs are distributed in both sides, carry out the left and right acoustic channels audio signal transmission; One leg is positioned at the opposite side of rubber base, and a leg and metal shell conducting, and three, four legs and plastics shell fragment are distributed in the opposite side of plastic seat.
