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 etc.

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 socket on using the computer front panel, the certain noise jamming of audio producing that meeting is exported the audio socket 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 socket 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 to the port output audio signal of corresponding earphone socket, promptly shielded the earphone socket audio signal on the computer rear board, the only output of the earphone socket on the computer front panel; 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, 14, the wire jumper on 15 earphone sockets that are respectively on the computer front and back panel, 13,16 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, the earphone socket of long service life.

For achieving the above object, the utility model is achieved through the following technical solutions: the socket female seat of earphone and microphone, comprise front casing, rear casing, terminal supportor, plastic cement seat and bonnet, plastic cement seat front end has for the circular hole that inserts male, and the inside of plastic cement seat has the draw-in groove that inserts five terminal supportors.Be used for the ground connection audio signal transmission in the draw-in groove in the middle of one leg is fixed on, and a leg and metal shell conducting, form good anti-interference electromagnetic shielding, in the draw-in groove in the middle of three legs and four legs are separately fixed at, three legs and four legs carry out the left and right acoustic channels audio signal transmission, two legs and five legs lead to plastic cement seat outside by the lengthening pin and make plate scolding tin usefulness, and the lengthening climbers are gone in the corresponding draw-in groove.Two legs, five legs are distributed in the opposite side of plastic cement seat, and two legs and five legs are converted to contact condition by disconnection in the same side, when male is inserted with the plastic cement shell fragment, and this is designed for the jumper switch of Intel HD Audio circuit.

Described plastic cement seat and insulation shell fragment integrated injection molding.

The beneficial effect of the socket female seat of earphone described in the utility model and microphone is, by constructing a plastic cement seat, the internal interval of plastic cement seat is provided with an insulation shell fragment, the inside of plastic cement seat also is provided with the draw-in groove that is used for the mounting receptacle leg, be inserted with a leg in the draw-in groove respectively, two legs, three legs, four legs, five legs, when male is not inserted, two legs and five legs are in off-state, when male is inserted, two legs and five legs are in contact condition, when male is inserted the socket female seat of the front panel that is installed in computer, make the socket female seat shielding of the rear board of computer, otherwise, when male is inserted the socket female seat of the rear board that is installed in computer, make the socket female seat shielding of the front panel of computer, thereby reach the effect that improves tonequality, this design meets the jumper switch of Intel HD Audio circuit, and male withdraws from the back switch disconnection that resets.Have simple in structure, manufacture easily, cost is low, and not fragile, the advantage of long service life.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the socket female seat of earphone and microphone, comprise front casing 2, rear casing 3, plastic cement seat 1 and bonnet 4, plastic cement seat 1 front end has for the circular hole that inserts male, be provided with an insulation shell fragment 11 in the plastic cement seat 1, described plastic cement seat 1 and insulation shell fragment 11 integrated injection moldings, the inside of plastic cement seat 1 has the draw-in groove that inserts five terminal supportors, its structure is: a leg 5 is the ground connection audio signal transmission, an and leg 5 and metal front casing 2, rear casing 3 conductings, form good anti-interference electromagnetic shielding, three legs 6 and four legs 7 are separately fixed in middle two draw-in grooves, carry out the left and right acoustic channels audio signal transmission, two legs 8, five legs 9 are distributed in the opposite side of plastic cement seat, with plastic cement shell fragment 11 in the same side, draw outside the rubber base respectively by two lengthening pin 10, lengthening pin 10 is separately fixed in the draw-in groove on both sides, when male 12 is inserted, plastic cement shell fragment 11 is pressed five legs 9, make two legs 8 and five legs 9 be converted to contact condition by off-state, thereby form a pair of jumper switch, but two legs 8, five legs 9 and male 12 insulation.

The socket female seat of earphone of the present utility model and microphone is installed on the front panel and rear board of computer, male 12 is inserted front panel socket female seat, transmit by a leg 5 ground signallings, three legs 6 and four legs 7 carry out a left side, the right channel audio signal transmission, two legs 8 contact with five legs 9 simultaneously, electrically connect conducting by this signal is imported chip, to be installed in the socket female seat audio signal shielding of computer rear board by chip output control signal, otherwise, when male 12 is inserted the socket female seat of computer rear board, then the socket female seat audio signal with the computer front panel shields, thereby reaches the effect that improves tonequality.
