Below in conjunction with drawings and Examples, the present invention is described in detail.
Fig. 2 is the plug of the earphone of the embodiment of the present invention and the structural representation of jack.As shown in Figure 2, the earphone of one embodiment of the present invention comprises plug 200.Jack 400 is corresponding with plug 200 to be designed.
Fig. 3 is the stereogram of the plug in Fig. 2.Fig. 4 is the upward view of the plug in Fig. 2.Fig. 5 is the front view of the plug in Fig. 2.As in Figure 3-5, plug 200 comprises header body 210 and two lug bosses 220.Wherein, header body 210 is in cylinder, and header body 210 comprises plug sidewalls 211 and plug bottom surface 212.Two lug bosses 220 to be arranged in plug sidewalls 211 and to stretch out.Lug boss 220 can be cuboid, square or cylinder etc.The outer surface of plug bottom surface 212 is provided with conductive layer.In the present embodiment, lug boss 220, in square, two faces 221 and 222 of lug boss 220 is all provided with conductive layer.
Fig. 6 is the schematic diagram of the plug connection wire in Fig. 2.Refer to Fig. 6, the conductive layer of plug bottom surface 212 is connected with earth lead 310, the conductive layer of two lug bosses 220 is connected to L channel wire 320 and R channel wire 330.The inner hollow of header body 210, for the L channel wire 320 that holds the earth lead 310 that is connected with the conductive layer of plug bottom surface 212 and be connected respectively with the conductive layer on two lug bosses 220 and R channel wire 330.The earplug (not shown) of earth lead 310, L channel wire 320 and R channel wire 330 all frames connecting with headphone 100.
Fig. 7 is the stereogram of the jack in Fig. 2.As shown in Figure 7, jack 400 comprises jack body 410 and two grooves 420.Jack 400 is corresponding with plug 200 to be designed, and plug 200 can insert in jack 400.
Wherein, jack body 410 is in cylinder, and for holding header body 210, jack body 410 comprises jack sidewall 411 and jack bottom surface 412.Two grooves 420 are arranged on jack sidewall 411.Groove 420 is the sliding rail of lug boss 220.Groove 420 comprises an extension 421, and this extension 421 is along the unidirectional extension of circumferencial direction of jack bottom surface 412, and extension 421 is for holding lug boss 220.The profile design in the shape of groove 420 and extension 421 all respective protrusions portion 220, such as when lug boss 220 in cuboid or cylinder time, extension 421 also correspondence is designed to cuboid or cylinder, and groove 420 can the corresponding profile design adopting cuboid or cylindrical line sliding track.The inner surface of jack bottom surface 412 is provided with conductive layer.In the present embodiment, extension 421 corresponds to lug boss 220 also in square, and two faces 4211 and 4212 of extension 421 are all provided with conductive layer.Especially, the conductive layer described in the present invention all can adopt the electric conducting material of prior art to make, such as, adopt metal level, repeat no more herein.The conductive layer of jack bottom surface 412 is connected with the audio frequency earth lead of mobile terminal inside, the conductive layer of two extensions 421 is connected to audio frequency L channel wire and the audio frequency R channel wire of mobile terminal inside.
In the present embodiment, two lug bosses 220 of plug 200 are arranged in the plug sidewalls 211 and position of close plug bottom surface 212, and two of jack 400 extensions 421 are arranged on the groove 420 and position of close jack bottom surface 412.
In addition, also two lug bosses 220 are symmetricly set in plug sidewalls 211 in the present embodiment, and two grooves 420 are symmetricly set on jack sidewall 412.Certainly, in other embodiments, also can by lug boss 220 and the asymmetric setting of groove 420.When plug 200 inserts the jack 400 be positioned on mobile terminal, header body 210 and lug boss 220 slide respectively in jack body 410 and groove 420, after header body 210 is inserted into the bottom of jack body 410, rotary connector 200 makes the lug boss 220 of header body 210 both sides enter extension 421, thus makes plug 200 not easily come off out from jack 400.Plug 200 and jack 400 are compact siro spinning technology, when after plug 200 with jack 400 compact siro spinning technology, conductive layers make contact on the inner surface of the conductive layer on the outer surface of plug bottom surface 212 and jack bottom surface 412 conducting, conductive layer on lug boss 220 two faces 221 and 222 is respectively with the conductive layers make contact on extension 421 two faces 4211 and 4212 and conducting, like this, the audio signal of mobile terminal 500 just can be passed in the earplug of earphone 100 by the conductive layer of conducting.
Fig. 8 is plug and the jack tight connecting device schematic diagram of the embodiment of the present invention.As shown in Figure 8, in the present embodiment, a face 4211 of extension 421 is inwardly provided with one can by the shell fragment 4213 compressed.After lug boss 220 starts to be rotated into extension 421, lug boss 220 compresses shell fragment 4213, shell fragment 4213 is compressed in backward extension 421 and extends, after lug boss 220 enters extension 421 completely, whole lug boss 220 is just locked in extension 421, shell fragment 4213 plays the effect of a snap close, if without external force, lug boss 220 just not easily comes off out from extension 421.When in the other direction firmly rotary connector, lug boss 220 is rotated extension 421, and lug boss 220 slides out from groove 420 again, finally completes being separated of plug 200 and jack 400.In other embodiments, on of a lug boss face, also can be arranged to that there is a projection further, to increase the compression stress to shell fragment, thus the compactness that enhancing lug boss 220 is connected with extension 421.
The embodiment of the present invention additionally provides a kind of mobile terminal 500, and as shown in Figure 9, this mobile terminal 500 comprises the earphone jack 400 described in above-described embodiment, repeats no more herein.Mobile terminal 500 in the present invention comprises the mobile phone or palmtop PC etc. of prior art.
Be different from the situation of prior art, the space that earphone of the present invention takies mobile terminal inside is in use less, and front or the back side of mobile terminal can be arranged at due to the earphone jack being mated use, thus be conducive to the lightening design of mobile terminal, and add elasticity and the flexibility of mobile terminal design.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
