The utility model includes an antenna which is arranged on the shell body and consists of an antenna main body, a feed-in part and a grounding part and a feed-in terminal and a grounding terminal, one end of which is contacted with the mainboard. The module is characterized in that the feed-in part and the grounding part are provided with a protruding point array with the surface contacted the feed-in terminal and the grounding terminal through an adhesive. The oxidation layer on the surface of the feed-in terminal and the grounding terminal is broken by the contacting positive pressure produced by the equal protruding point array and the adhesive. Thereby, the feed-in part and the grounding part can respectively form an electric conduction with the feed-in terminal and the ground terminal.
Description
Technical field
The utility model is about a kind of antenna for mobile phone module, is meant a kind of contact interface damage of can not causing especially, the stable reception of signal of guaranteeing to communicate by letter, and can simplified structure and processing procedure, the antenna for mobile phone module that reduces cost.
Background technology
The prosperity of communication science and technology, very general of staff one machine at present, and according to the quantity of the global mobile phone of statistics because broadband, moulding and multi-functionally constantly push away old adding fuel to the flames and can break through 600,000,000.The convenience that mobile phone is borderless, borderless is got to pick out in mobile phone and can be received electromagnetic Anneta module with the various communication frequency bands of radiation respectively, be with, the setting of Anneta module is one of a very important structure for mobile phone.
The Anneta module of known mobile phone comprises antenna, feed-in terminal separated and earth terminal at least, and wherein this feed-in terminal separated can contact with motherboard with an end of earth terminal, and the other end then contacts with the feeding portion and the grounding parts of antenna respectively, uses the transmission communication signal.Present built-in antenna for mobile phone has two main flows, the one, be stamped to form with copper sheet, another then is the copper foil antenna made from lithography or mode of printing, but the former is difficult for being attached on the curved surface of housing, thereby between antenna and the surface of shell existing between the crack easily the vibration environment under, make the communication signal instability and have the noise generation,, the shortcoming of easy damage is arranged because of its thin contact interface though the latter has excellent curved surface to attach property.And the feeding portion of known antenna, grounding parts and feed-in terminal separated, earth terminal are adopted the electric connection of contact, also are subject to the influence of little corrosion (Fretting) that shake, and the signal instability and the shortening in life-span cause communicating by letter.
Summary of the invention
The purpose of the utility model antenna for mobile phone module, promptly, fixed connection the between the feeding portion, grounding parts that is to provide a kind of antenna and feed-in terminal separated, the earth terminal, on the one hand to paste the connected mode that replaces contact, to avoid the shortcoming of the easy scratch of film interface, then be suitable for vibration environment on the other hand, do not have the misgivings of little corrosion of shaking, can guarantee to communicate by letter signal stable reception and communication quality, and can simplify structure and processing procedure, reduce cost and improve useful life.And, more can be installed in the casing side because of feed-in and earth terminal, the function of the only surplus contact antithesis of the contact on the motherboard (Pad), thereby area can dwindle.
The another purpose of the utility model antenna for mobile phone module, be that mat salient point array is as connecting interface, so that the electric connection between antenna and feed-in/earth terminal, and the employed viscose unification of the mechanical fixation between antenna and casing, thereby can simplify part manufacturing and antenna assemblies.
For achieving the above object, the utility model antenna for mobile phone module comprises: the antenna of tool antenna body, feeding portion and grounding parts, reach feed-in terminal separated, earth terminal, it is characterized in that: this feeding portion and grounding parts are provided with the salient point array, its surperficial mat viscose is connected with the contact site of earth terminal with this feed-in terminal separated respectively, use generation contact normal pressure and make these salient point arrays puncture the oxide layer on this feed-in terminal separated and earth terminal surface, make this feeding portion and grounding parts form with this feed-in terminal separated and earth terminal respectively and electrically conduct.
The utility model compared with prior art has following conspicuous substantive distinguishing features and advantage: this salient point array is best with the rounded projections arranged, and at least one drift angle of triangle array is to form breach, is used for air/viscose row is overflow.This viscose can be adopted pressure-sensing glue (Pressure Sensitive Adhesive), and, in pasting process, mat smooths and exerts pressure, squeeze viscose and air in the closed area, thereby form pressure reduction and produce a net pressure in interface, this net pressure is together with the adhesion of viscose, make the effect of described closed area as small sucker, to provide to keeping that connecting interface electrically contacts.The utility model antenna for mobile phone module is a feature again, is further to be provided with protective layer, is to cover to be fixed on this antenna, so that reinforcement power to be provided, helps to keep the stable normal pressure of these salient point arrays.
