The four copper sheets are welded with the PCBA in a positioned manner, namely, the copper sheets of the grounding end and the right channel end are respectively welded to the left end and the right end of the upper surface of the PCBA; the PCBA is clamped in the copper sheets of the left channel end and the MIC connecting end; and the copper sheets of the left channel end and the MIC connecting end are respectively welded to the upper surface and the lower surface of the PCBA. The four copper sheets of the bus seat are directly connected with the PCBA in a positioned manner, four connecting wires are omitted, cost on materials is reduced, four welding spots are omitted, a positioning jig which is used during welding is not required, the welding efficiency is improved, the welding spots are firm, a phenomenon of the welding spots are flushed away by plastics generated in first in-mold injection molding is avoided, and the yield of a product is improved.
Description
Technical field
The present invention relates to digital moving-tv earphone antenna, particularly a kind of female seat copper sheet is directly welded on the digital moving-tv earphone antenna on PCBA assembly.
Background technology
Along with the fast development of mobile terminal device and network, increasing terminal equipment has all been equipped with movable digital TV functions, particularly in Olympic Games year and Football World Championship year, the demand of the mobile digital TV of mobile terminal device is especially obvious, there is the mobile terminal device of mobile digital TV function, people's information of can coming to matches in the place of the network coverage whenever and wherever possible.But traditional mobile terminal Tiebar structure, need to take certain space at now emerging narrow and small mobile terminal device, this has caused very large puzzlement to mobile terminal, so in this case, DTV earphone antenna has just arisen at the historic moment, it be convenient for carrying, and detachable, possesses again the superior signal matching in excellence or beauty with traditional telescopic antenna.
As shown in Figure 1, the PCBA assembly 2, lenticular wire 3 and the plug 4 that comprise antenna female seat 1 and welding successively of DTV earphone antenna at present, between female seat (traditional female seat) and PCBA assembly, need to connect and weld with wire, and after welding, the solder joint of the solder joint of wire and PCBA assembly and lenticular wire and PCBA assembly is easily taken off by the plastic cement punching of in-mould injection for the first time, cause electrical property bad, and this bad be unrepairable, not only production and assembly difficulty, also cause manufacturing cost to rise, efficiency is low.
Utility model content
In view of this, it is high that the technical problems to be solved in the utility model is to provide a kind of make efficiency, constitutionally stable digital moving-tv earphone antenna.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
Digital moving-tv earphone antenna, comprise female seat and the PCBA assembly, lenticular wire and the plug that are connected successively, described female seat comprises glue shell and is wrapped in glue shell and stretches out representative left and right sound channels end, the earth terminal of glue shell and connect four copper sheets of MIC end, and described four copper sheets are together with PCBA assembly positioning welding.
Preferably, the copper sheet of described earth terminal, R channel end is welded on respectively the two ends, left and right of PCBA assembly upper surface, and L channel end and the copper piece clip PCBA assembly that connects MIC end be in wherein, and is welded on respectively the upper and lower faces of PCBA assembly.
Preferably, the copper sheet of described left and right sound channels end and earth terminal is welded on the same face of PCBA assembly, and the copper sheet that connects MIC end is welded on the another side of PCBA assembly.
Further preferably, described PCBA assembly be provided with via, described via is by covering copper cash and the pad conducting at copper sheet place that connects MIC end on PCBA assembly.
Concrete, the copper sheet of described earth terminal and R channel end, through PCBA assembly, passes after part bends and is welded on PCBA assembly.
Preferably, the thickness of described four copper sheets is between 0.2-0.3mm.
Compared with prior art, the utlity model has following advantage:
(1) four of female seat of the present utility model copper sheets are directly connected location with PCBA assembly, have reduced by four connecting lines, reduce material cost, and the localization tool when reducing by four solder joints simultaneously and not needing to weld improves welding efficiency;
(2) the utility model pad is firm, reduces by the plastic cement of in-mould injection for the first time and rushes de-situation, improves product yield.
