Specific embodiment
The mobile terminal that embodiment provides in order to further illustrate the present invention, is retouched in detail with reference to the accompanying drawings of the specification
It states.
Referring to Fig. 4, mobile terminal provided in an embodiment of the present invention includes circuit board support 3 and offers plug channels
The mobile terminal shell 2 of entrance 1；Fig. 5 is referred to, circuit board 4 is equipped between mobile terminal shell 2 and circuit board support 3；It please join
Fig. 3 is read, is connected on circuit board 4 with the first plug channels 43, the first plug channels 43 with plug channels entrance 1 (see Fig. 4)；
The support ring 6 being connected with circuit board 4 is equipped in first plug channels 43, support ring 6 is used to that headset plug to be supported and led
To；The electroconductive elastic sheet group for being contacted with the signaling interface on headset plug is additionally provided on circuit board 4, so that in headset plug
Circuit is connected with the circuit integrated on circuit board.
In use, headset plug is inserted into from plug channels entrance 1 in the first plug channels 43, and passes through support ring 6 and support
And guiding, the signaling interface on headset plug is made to be connected with the electroconductive elastic sheet in the electroconductive elastic sheet group on circuit board 4, it is ensured that earphone
The circuit integrated on circuit and circuit board in plug correctly connects, and works normally earphone.
From above-mentioned use process it is found that in mobile terminal provided in this embodiment, the first plug carried on circuit board 4 leads to
Road 43 is connected with the plug channels entrance 1 opened up in mobile terminal shell 2, is additionally provided with and is used for and headset plug on circuit board 4
On signaling interface contact electroconductive elastic sheet group；When headset plug enters the first plug channels 43 from plug channels entrance 1, lead
Electroconductive elastic sheet in electric shrapnel group can just be contacted with the signaling interface on earphone, moreover, be additionally provided in the first plug channels 43 with
The connected support ring 6 of circuit board 4, support ring 6 can be supported and be oriented to headset plug, ensure the circuit on headset plug
Circuit that can be correctly with being integrated on circuit board 4 is connected to form conducting circuit, and earphone is enable to work normally.In addition, plug
Feeder connection 1 can not only provide the entrance into the first plug channels for headset plug, equally also have branch to headset plug
Support and guiding role；As it can be seen that the present embodiment is supported and is oriented to headset plug by support ring 6 and plug channels entrance 1,
And pass through the electroconductive elastic sheet in electroconductive elastic sheet group and be in contact with the signaling interface on headset plug, it ensure that the electricity on headset plug
Road is correctly connected with the circuit integrated on circuit board 4, without the use of plastic cement female seat 12, has fundamentally prevented plugging repeatedly
During headset plug, plastic cement female seat 12 be located at plug channels entrance 1 plastic cement cracking the problem of.Moreover, the present embodiment
The conduct piece used is with flexible and thickness very little electroconductive elastic sheet, and support ring is for being supported and lead to headset plug
To the diameter matches of diameter and headset plug, this also avoids the unnecessary increases of mobile terminal thickness.
By taking 1 a diameter of 3.6mm of plug channels entrance in mobile terminal shell as an example, the headset plug of a 3.5mm from
After plug channels entrance 1 enters the first plug channels, electroconductive elastic sheet corresponding with electroconductive elastic sheet group is connected, and passes through support
Ring 6 and plug channels entrance 1 are supported and are oriented to, and make the signaling interface on headset plug is corresponding with electroconductive elastic sheet group to lead
