Abstract

The utility model relates to an improved earphone socket. The utility model is mainly formed by that a horizontal foot connecting part is formed at the outer end of each terminal; the foot connecting parts are extended to the left and the right lateral points of the bottom part of a main body of the socket; two sides of the main body of the socket are provided with corresponding through holes; in addition, a high bending part is formed at the upper end of each connecting foot, and the height of each of the through holes arranged at two sides of the main body of the socket is increased. Thereby, the utility model has the advantages that assembly is convenient, and a circuit board can be bent to become thinner.

Description

The earphone socket of improvement

The utility model relates to a kind of earphone socket.

At present, as shown in Figure 1, be a kind of known earphone socket, this earphone socket system is assembled by a jack body 1, a lid 2 and several terminals 3, and the antetheca of this jack body 1 is provided with a hole seat 10, these hole seat 10 inside have a jack 12, can the use as a pretext end 31 that connects of son of this jack 12 and to extending to jack body 1 inside, this earphone socket is pegged graft, is welded on the circuit board, and the plug of earphone can be plugged on the jack 12 of hole seat 10, and can contact with terminal 3, to reach the transmission of signal.

On the above-mentioned known circuit board that earphone socket welded, pin portion 31 corresponding perforation with terminal 3 must be set in advance, the pin portion 31 of terminal 3 is welded on the circuit board, cause the inconvenience of earphone socket and circuit board assembling, and for the ease of the setting of perforation, circuit board needs certain thickness, and thicker circuit board takes up room unavoidably, especially be not suitable for and stress compact mobile phone, on walkman (CD), mini tape recorder or some the small-sized audio-visual appliances.

In view of this, the purpose of this utility model provides a kind of earphone socket of improvement, it be the solid welding of pin portion on circuit board, and not be used in the perforation that grafting usefulness is set on the circuit board, assemble more conveniently, circuit board can also be thinner, and pin portion upper end forms a high kink in addition.

The purpose of this utility model is achieved in that a kind of earphone socket system of improvement is by a jack body, one lid and several terminals are formed, this jack body is provided with a hole seat, this seat inside, hole has a jack, this jack extends to jack body inside, the internal fixation several terminals of this jack body, lid is combined in the jack body openend, terminal the inner of part is formed with contacting part and protrudes in jack, it is characterized in that: the terminal outer end forms horizontal pin portion, this pin portion stretches out in the jack body bottom, left, right two side places, jack body two sides are provided with corresponding open-work, and stretch out for foot, terminal three pin portions upper end forms a high kink, and the open-work height of jack body two sides is increased, and the high portion bending of mating terminals.

Described high kink protrudes outside the open-work of jack body.

Owing to adopt such scheme: easy to assembly, the circuit board bendable is thin, and in the time of also can avoiding welding foot, scolding tin infiltrates inner from the open-work of jack body.

Below in conjunction with drawings and Examples the utility model is further specified.

The three-dimensional combination figure of the known earphone socket of Fig. 1;

Fig. 2 is the utility model first embodiment stereogram;

Fig. 3 is that the utility model first embodiment is to putting stereogram;

Among the figure: 1. jack body 10. hole seats 11. caulking grooves 12. jacks 13. open-works 2. lids 3. terminals 30. contacting parts 31. pin portions 32. high kink 4. circuit boards 5. plugs

First embodiment, shown in Fig. 2～5, system is by a jack body 1, one lid 2 and several terminals 3 assemble, the front side wall of this jack body 1 is provided with a hole seat 10, seat 10 inside in hole have a jack 12, this jack 12 also extands rearward to jack body 1 inside, this jack body 1 inside is provided with a beacon caulking groove 11 in addition, can be in order to the interlocking several terminals, make terminal 3 be fixed on jack body 1 inside, terminal 3 the inners of part are formed with contacting part 30 and can protrude in jack 12, so that contact with the plug of butt joint earphone, terminal 3 outer ends are bent to form horizontal pin portion 31, and this pin portion 31 also stretches out in jack body 1 bottom, left, right two side places, jack body 1 two sides also are provided with corresponding open-work 13 and stretch out for pin portions 31.

As Fig. 6, shown in 7, son 3 the pin 3 of can using as a pretext is weldingly fixed on the circuit board 4, so that be applied on the device such as mobile phone, the plug 5 of earphone can be plugged in the jack 12 of hole seat 10, and the contacting part 30 of the son 3 of can using as a pretext touches mutually with the plug 5 of earphone, to reach the transmission of signal, present embodiment mainly is that terminal 3 outer ends are formed horizontal contact site 31, make pin portion 31 can be seated on the circuit board 4 reposefully, and be fixed on circuit board 4 with welding manner, and need be provided with perforation on circuit board 4, earphone socket and circuit board assembling are more convenient, and circuit board can adopt thin design, saving takes up room, and is particularly useful for stressing compact mobile phone, walkman (CD), on mini tape recorder or some the small-sized audio-visual appliances.

Moreover, shown in Fig. 5～10, also terminal 3 can be done one changes, pin portion 31 upper ends of this terminal 3 can be bent to form a high kink 32, and the open-work 13 of jack body 1 highly suitably increased, the high kink 32 of terminal 3 is engaged in the open-work 13 of jack body 1, the setting of high kink 32, in the time of can being welded on circuit board 4 in pin portion 31, prevent that scolding tin from infiltrating inner by the open-work 13 of jack body 1, the phenomenon that can effectively prevent stannize takes place, and as shown in figure 11, this high kink 32 also can protrude outside the open-work 13 of jack body 1.

The utility model has improved known earphone socket in sum, and the circuit board of its welding need be provided with perforation, assembling inconvenience, the rare new product of problem such as take up room.
