Embodiment
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 3, a kind of earphone jack dust plug, is applied on electronic equipment 6, and wherein, electronic equipment 6 has earphone jack 5 and antennal interface 2 (referring to Fig. 1 and Fig. 2), earphone jack dust plug 7 comprises fixed part 3; Not only earphone jack dust plug 7 can be plugged in earphone jack 5 but also can be plugged in antennal interface 2; When not inserting earphone in earphone jack, earphone jack dust plug 7 is plugged in earphone jack 5, and fixed part 3, for shutoff earphone jack 5, prevents dust etc. from entering into electronic equipment 6 through earphone jack 5 inner; When needing grafting earphone in earphone jack 5, earphone jack dust plug 7 is extracted in earphone jack 5, and be plugged in antennal interface 2, prevent earphone jack dust plug 7 from losing.
In order to increase the function of earphone jack dust plug 7, earphone jack dust plug 7 in the present embodiment also comprises the signal transmitting and receiving portion 1 be fixedly connected on fixed part 3, when earphone jack dust plug 7 is plugged in antennal interface 2, signal transmitting and receiving portion 1 is electrically connected with the antenna element of electronic equipment; When in the more weak area of signal, as mountain area etc., can earphone jack dust plug 7 be plugged in antennal interface 2, to strengthen the signal transmitting and receiving ability of electronic equipment, and when user uses earphone, earphone jack dust plug 7 is plugged on the loss that can also prevent earphone jack dust plug 7 in antennal interface 2.
