The embodiment of the present invention provides a kind of mobile terminal, comprise housing, this housing comprises the first mounting groove for installing side switch, the bottom surface of this first mounting groove is provided with the DOME that connects FPC, the inner surface of above-mentioned side switch, the position of corresponding DOME is provided with conductive base, in addition, the inner surface of side switch is provided with support column, the bottom surface of described first mounting groove is also provided with support, and at pressing side switch, conductive base contacts with DOME, DOME deforms and by FPC during circuit turn-on, support column contacts with support.
So, when pressing side switch, conductive base contacts with DOME, DOME is deformed and by FPC during circuit turn-on, because support column can contact with support, therefore in the process of above-mentioned pressing side switch, support can provide support power to described support column, can support to make support column at pressing position place to side switch.Avoid because pressing position is not corresponding with the position of DOME, and cause side switch generation warpage.
Further, in order to be arranged on the bottom surface B of above-mentioned first mounting groove 101 by above-mentioned support 40 and the DOME that is connected with FPC, as shown in Figure 2 a, this housing 01 also comprises the second mounting groove 102 be connected with the first mounting groove 101.Wherein, the bearing of trend of the first mounting groove 101 is vertical with the bearing of trend of the second mounting groove 102.It should be noted that, the bottom surface B of the first mounting groove 101 is an inwall of the second mounting groove 102.
In the case, by being connected with the DOME of FPC by above-mentioned second mounting groove 102, can be installed on the bottom surface B of above-mentioned first mounting groove 101.In addition, the bottom surface B due to the first mounting groove 101 is an inwall of the second mounting groove 102, therefore by above-mentioned support 40 support installing after the second mounting groove 102, the object of bottom surface B support 40 being arranged at the first mounting groove 101 can be reached.Therefore the second mounting groove 102 is that the bottom surface B DOME and support 40 that are provided with FPC being installed on the first mounting groove 101 provides installation approach.
It should be noted that, above-mentioned FPC, except being provided with the circuits for triggering that match with a DOME, can also be provided with the circuits for triggering matched with other DOME, or for realizing the circuit structure of other functions.Therefore the area of FPC is larger for single DOME.And above-mentioned first mounting groove 101 or the second mounting groove 102 are only for realizing the installation of single DOME.Therefore as shown in Figure 3, this FPC can extend multiple installation region 301, each installation region 301 correspondence installs a DOME.And this installation region 301 size is less than the bore size of the first mounting groove 101 or the second mounting groove 102, with the bottom surface B making the DOME being installed on this installation region 301 can be mounted to the first mounting groove 101 by the second mounting groove 102.
Further, the quantity of the present invention to above-mentioned support column 2022 does not limit.Because DOME is corresponding with the position of conductive base 2021.And conductive base 2021 is generally positioned at the centre position of side switch 20, when therefore pressing position is not corresponding with conductive base 2021 or DOME position, upper end or the lower end of side switch 20 generally can be pressed into.Therefore preferred, as shown in Figure 2 c, a support column 2022 can be respectively set at the upper/lower terminal of side switch 20, and this DOME is between above-mentioned two support columns 2022.
So, in the process of pressing, when pressing position is positioned at the upper end of side switch 20, the support column 2022 being positioned at this side switch 20 upper end can contact with support 40.In the case, support 40 can provide support power to the support column 2022 being positioned at side switch 20 upper end, can support to make this support column 2022 at pressing position place to the upper end of side switch.It should be noted that, because this support 40 is arranged at the bottom surface B of the first mounting groove 101, in the process of pressing side switch, support 40 can extrude the bottom surface B of the first mounting groove 101, therefore support 40 provides support power to support column 2022, the reaction force that the bottom surface B deriving from the first mounting groove 101 provides when being squeezed.
Or when pressing position is positioned at the lower end of side switch 20, in like manner support column 40 can provide support power to the support column 2022 being positioned at side switch 20 lower end, can support to make this support column 2022 at pressing position place to the lower end of side switch.
On this basis, when the upper/lower terminal of side switch 20 is provided with support column 2022, as shown in Figure 4, support 40 comprises crossbeam 401, and is positioned at the column 402 at crossbeam 401 two ends.Region between above-mentioned two columns is to should the position of DOME.In addition, as shown in Figure 2 d, a support column 2022 is corresponding with the position of a column 402.So, in the process of pressing side switch 20, on side switch 20, the support column 2022 at lower two ends can contact one by one respectively at the side surface of the column 402 at crossbeam 401 two ends near support column 2022, and the side surface deviating from support column 2022 of two columns 402 contacts with the bottom surface B of the first mounting groove 101, thus in the process of pressing, a column 402 can provide support power to the support column 2022 being positioned at side switch upper end, to support the upper end of side switch 20, or another column 402 can provide support power to the support column 2022 being positioned at side switch lower end, to support the lower end of side switch 20.
In addition, the column 402 due to crossbeam 401 and two ends can form the support 40 of door type, is surrounded by DOME.Thus avoid the impact of support 40 on the spacing of DOME and conductive base 2012 is set, thus avoiding side switch 40 to press in the process that warpage occurs, DOME can not be affected and normally work.
Further, in order to the DOME being connected with FPC being installed on the bottom surface B of the first mounting groove 101, one side surface that can deviate from DOME in the above-mentioned installation region 301 of FPC attaches double faced adhesive tape, DOME to be fixed on the bottom surface B of the first mounting groove 101 by the installation region 301 on FPC.But because the thickness of FPC is generally about 0.1mm, therefore FPC pliability is comparatively large, easily bends in the first mounting groove 101 or the second mounting groove 102, be not easy to fix in the process of installing.Therefore, the side of DOME installed surface can be deviated from FPC, in installed position (i.e. above-mentioned installation region 301) the setting supporting bracket 302 as shown in Figure 5 of corresponding DOME.Wherein, this supporting bracket 302 can adopt hard resin or metal material to form.Thus can improve by supporting bracket 302 hardness being provided with the above-mentioned FPC installation region 301 of DOME.
On this basis, because support 40 needs to be installed in the second mounting groove 102, and the bottom surface B of the first mounting groove 101 is arranged at by this second mounting groove 102.Therefore for the ease of support 40 and the FPC that is provided with supporting bracket 302 and DOME to be arranged at the bottom surface B of the first mounting groove 101 by the second mounting groove 102.First support 40 and the FPC being provided with supporting bracket 302 and DOME can be assembled.And then assembly is installed.
Concrete, first the above-mentioned FPC being provided with supporting bracket 302 and DOME can be pasted on the side that support 40 deviates from side switch 20, to realize above-mentioned assembling, then at bottom surface B assembly being arranged at the first mounting groove 101 by this second mounting groove 102.
But, above-mentionedly directly the FPC being provided with supporting bracket 302 and DOME is fitted on support 40, the edge of FPC can be made to expose, in the process of installing, easily cause the damage at FPC edge.Therefore, the first groove 403 is as shown in Figure 5 provided with in the side that support 40 deviates from side switch 20, for embedding above-mentioned supporting bracket 302.Concrete, as shown in Figure 6 a, be pasted in the first groove 403 of support 40 by the FPC being provided with supporting bracket 302 and DOME by double faced adhesive tape 500, the structure after installation is as shown in Figure 6 b.
So, as shown in Figure 5, a side surface that supporting bracket 302 can be made to deviate from DOME deviates from a side surface of DOME lower than support 40, or the side surface that supporting bracket 302 side surface that deviates from DOME and support 40 deviate from DOME is equal together.Thus make the FPC of supporting bracket 302 on the surface, side of DOME can be arranged in above-mentioned first groove 403, thus the damage to FPC in installation process can be avoided.
And, in order to improve installation accuracy, when the assembly of the FPC and support 40 that are provided with supporting bracket 302 and DOME is installed in the second mounting groove 102, if support 40 contacts with the side inwall of the second mounting groove 102, and the supporting bracket 302 that FPC deviates from DOME side contacts with the opposite side inwall of the second mounting groove 102, the making tolerance of support 40, supporting bracket 302 and the second mounting groove 102 can be made all to be superimposed in location tolerance, thus to reduce installation accuracy.Therefore, by arranging the first groove 403 on support 40, and the bracing frame 302 being provided with DOME and FPC is embedded in the first groove 403, can make to only have the both sides of support 40 to contact with the inwall of the second mounting groove 102 both sides respectively when the FPC being provided with supporting bracket 302 and DOME is installed in the first mounting groove 101 with support 40.
