Embodiment
In order to make purpose, technical scheme and the advantage that to invent clearer; To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention carried out clear, intactly description, obviously; Described embodiment is a part of embodiment of invention, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the present invention protects.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the present invention proposes a kind of portable terminal external antenna embodiment.This portable terminal external antenna comprises: antenna body 2 and antenna housing 3; Wherein said antenna body 2 constitutes by aerial coil 20 with at these aerial coil 20 outside one deck insulators 21 that coat; Said antenna housing 3 is provided with takes in antenna body 2, is provided with the buckle 31 that is fixed with portable terminal in the bottom of antenna housing 3.
Specifically; The cavity wall of said storage cavity 30 be provided with two with antenna body 2 on insulator 21 stopper slot or the positive stop strip 34 that cooperate; Be that said insulator 21 outsides are provided with position limiting structure 211, the cavity wall of said storage cavity 30 is provided with positive stop strip or the stopper slot 34 that cooperates with position limiting structure 211; When the position limiting structure 211 in said insulator 21 outsides is positive stop strip, the cavity wall stopper slot of said storage cavity 30, vice versa.Being provided with the position limiting structure that cooperatively interacts and positive stop strip or stopper slot 34 in the cavity wall of storage cavity 30 and insulator 21 correspondences can make antenna body 2 cooperate the back fixed-site with antenna housing 3; Also increase simultaneously antenna body 2 and antenna housing 3 contacts area, more firm when making antenna body 2 with antenna housing 3 matching and fixing.
Because antenna body 2 carries out injection mo(u)lding respectively with antenna housing 3, and when bursting at the seams housing 3 moulding, preset the cavity 30 that can take in antenna body 2 above that, the antenna body 2 with two moulding cooperates assembling with antenna housing 3 again.Owing to after respectively antenna body 2 and antenna housing 3 being carried out injection mo(u)lding, need not adopt high temperature and high pressure environment in the operation; Therefore it is defective antenna body 2 electrical properties in follow-up assembling process, seldom to occur, thereby usually the electrical property to antenna body 2 before antenna body 2 and antenna housing 3 assemblings is being detected.Assembling can be just can stopped when defective scrapping occurring, and the raising efficiency of assembling need be antenna housing and antenna body opened in 2 minutes when or else qualified after needn't assembling by the time detecting before assembling; Avoid simultaneously at antenna body 2 after antenna housing 3 is injection-moulded in, occur need entire antenna being scrapped when defective, improve the utilization ratio of antenna associated components, reduce production costs.Only need carry out one-shot forming in process of production simultaneously, cause underproof probability in the minimizing external antenna production technology antenna body.
Even defective situation when antenna body 2 detects with antenna housing 3 assembling backs, occurs; Also can easily it be separated; Change qualified antenna body 2, also can avoid at aerial coil 2 after antenna housing 3 is injection-moulded in, occur need entire antenna being scrapped when defective.
In the present embodiment; Can be provided with at the sidewall of said storage cavity 30 and be ledge structure 33; The step 212 of this ledge structure 33 and antenna body 2 correspondence position settings closes joins, and makes that antenna body 2 and antenna housing 3 contacts area are bigger, further improves fixing fixing.Specifically; Said storage cavity 30 is made up of two column type cavitys with diameter; Wherein larger-diameter cavity is positioned at the outside of antenna housing 3r, in the inboard of antenna housing 3, forms ledge structures 33 two different-diameter cavity junctions than the cavitys of minor diameter.
The stopper slot on said storage cavity 30 cavity walls or the quantity of positive stop strip 34 also can be provided with as required, for example can be made as one, three or more.Combine production cost according to production technology, the quantity of this stopper slot or positive stop strip 34 is preferably two, and symmetry is if be evenly distributed on the cavity wall again.
Said the present invention also provides a kind of manufacture method of portable terminal external antenna like Fig. 6, and the manufacture method of this portable terminal external antenna comprises:
Step S11, the antenna body moulding is adopted the injection moulding mode that encapsulate is carried out in the aerial coil outside, and is formed at least one position limiting structure in the outside of antenna encapsulate;
Step S12, the moulding of injection moulding mode is adopted in the antenna housing moulding, the preset storage cavity of receiving antenna body on this antenna housing, making has at least one stopper slot that cooperates with position limiting structure or positive stop strip in this storage cavity;
Step S13, the assembling antenna is with antenna body described in above-mentioned steps S11 and the step S12 and the storage cavity matching and fixing on the antenna housing.
Among above-mentioned steps S11 and the step S12, after the antenna body moulding, can carry out the electrical property detection and antenna is carried out the electrical property detection it usually, the former can remove underproof antenna body, avoid occurring defective antenna body is assembled into antenna.
Among the above-mentioned steps S13, in order to make fixing more firm between antenna housing and the antenna body, can be earlier in the storage cavity of antenna housing or the antenna body outside apply glue, again with the storage cavity matching and fixing on above-mentioned antenna body and the antenna housing.
In the present embodiment, said step S11 and step S12 can be in no particular order in proper order.
Above embodiment is only in order to explaining technical scheme of the present invention, but not to its restriction; Although the present invention has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing; Perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of relevant art scheme break away from the spirit and the scope of various embodiments of the present invention technical scheme.
