Fig. 3 is FPC antenna of the present invention and portable terminal casing assembling schematic diagram.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, FPC antenna of the present invention comprises antenna body 1, and both sides arrange respectively the first stiffening plate 2 and the second stiffening plate 3 below antenna body 1.Antenna body 1 stage casing arranges two location holes 5, positioning antenna body when the leftward position of antenna body 1 arranges 6, three location holes of the 3rd location hole and is used for assembling with the portable terminal casing, and described FPC antenna is fixed by bonding method and portable terminal casing.
The relative traditional F PC antenna of FPC antenna of the present invention has increased stiffening plate, makes it can be assembled into the place that traditional antenna can not be assembled on the casing, takes full advantage of enclosure space; Process by the casing differential trench open, make the FPC antenna increase the groove medial surface, (N groove just has N medial surface, N 〉=1), increase antenna effective area, improve antenna adjustment cabling area, thereby greatly promoted antenna performance; Antenna of the present invention, its intensity, stability and reliability are higher, assemble more convenient.
The FPC antenna simultaneously arranges glue-line, in order to mount conveniently, the present invention covers release liners at FPC antenna body glue-line surface integral first, two location holes, 5 both sides arrange release liners and cut off line 7 in the stage casing, antenna feed point 4 also arranges release liners cut-out line 8 with the end that antenna body joins, and antenna feed point 4 other ends are established the release liners hand and torn position 9.
FPC antenna of the present invention and portable terminal casing assemble method are after traditional FPC antenna is increased stiffening plate, to be assembled into the casing the inside after structure optimization.Described casing through structure optimization is namely arranging the first groove 20, the second groove 30 as shown in Figure 2 in portable terminal casing both sides of edges, be used for the first stiffening plate 1 and 2 assemblings of the second stiffening plate that arrange with both sides, FPC antenna body below.Also need the installing hole on the position respective antenna that need fix up an aerial wire on the portable terminal casing that reference column is set.Reference column comprises the reference column 50 that corresponding two location holes 5 in the stage casing that is arranged on the position that need fix up an aerial wire arrange and the reference column 60 that is arranged on the corresponding location hole 6 of portable terminal casing perforation place, reference column 50 is used for the positioning antenna body, and reference column 60 is used for accurate positioning antenna feedback point and assembling machine casing.Fig. 2 embodiment has provided FPC two stiffening plate correspondences are offered two grooves at portable terminal casing edge preferred embodiment has been set, the quantity of the groove of offering on the setting of actual stiffening plate and the portable terminal casing can be according to the actual conditions setting, a stiffening plate for example is set on the antenna, a groove is set on the portable terminal casing, two above stiffening plates perhaps are set on the antenna, arrange two on the portable terminal casing with upper groove, stiffening plate and groove quantity are corresponding to be got final product.
