Description
Technical field
The present invention relates to the signal receiver technical field of mobile terminal, more particularly to a kind of aerial mounting structure and
Mobile terminal.
Background technique
Currently, mobile phone is more and more on the market uses aluminium alloy (AL6061, AL6063 etc.) material, to increase the outer of mobile phone
Metal-like is seen, appearance colour is enriched and reinforces complete machine intensity.The communication performance of mobile terminal is largely dependent on mobile whole
The antenna structure or radio-frequency structure at end, since aluminum alloy material itself can interfere radio-frequency antenna, therefore antenna solution now
Certainly scheme is all using a part of Al-alloy casing as radio frequency, this allows for radio-frequency structure and needs mainboard and Al-alloy casing
Connection constitutes a complete antenna or radio architectures.
It includes following several schemes: the first side that the mainboard with Al-alloy casing of mainstream, which connect antenna structure mainly, at present
Case: the structure of mobile phone generally aluminum alloy material, the implementation of antenna structure are paster antenna elastic slice on mainboard, antenna shrapnel
Z-direction corresponds to Al alloy shell body region and does laser carving, and antenna shrapnel, which by elastic force withstands Al-alloy casing, to carry out conducting and form day knot
Structure.Second scheme: mobile phone center is the structure of aluminum alloy material, and the implementation of antenna structure is paster antenna bullet on mainboard
Shell foot is arranged in piece, antenna shrapnel X or Y-direction, and shell foot corresponds to Al alloy shell body region and does laser carving, and antenna shrapnel pushes down aluminium by elastic force
Alloy shell carries out conducting and forms antenna structure.The third scheme: at the top of mobile phone and tail portion is aluminum alloy decorating part structure, antenna
The implementation of structure is that first antenna elastic slice is spot welded on aluminum alloy decorating part, and the second antenna shrapnel of patch on mainboard is main
Flexible circuit board (FPC, Flexible Printed Circuit) is pasted on lower plastic casing, first antenna elastic slice and the second antenna
Elastic slice is connected to form antenna structure by FPC.
For the antenna attachment structure of the third scheme, aluminum alloy decorating part need with the antenna shrapnel of stainless steel antenna into
Row spot welding.Aluminium alloy still uses pulsed argon arc welding to be welded with stainless steel using vacuum electron beam welding, due to aluminium alloy
Physical and chemical performance between stainless steel differs greatly, and when being welded, aluminium side is both needed to preheat, in the welding process, molten bath
Center needs to be biased to aluminum side, in addition, before welding, it is also necessary to be placed on guarantor after removing the oxidation film to metallic luster of aluminum alloy surface
In incubator, pulsed argon arc welding welding finally is obtained with vacuum electron beam.Since the physical and chemical performance of aluminium alloy and stainless steel differs greatly,
The frangible compounds for being directly connected to generate AL and Fe easily on joint face of the two, lead to weld relatively difficult, weldering between the two
Connect second-rate, radio-frequency contact is unreliable.

In view of this, the embodiment of the present invention provides a kind of aerial mounting structure and mobile terminal, to solve existing antenna
Connection structure welding difficulty, poor welding quality, the insecure problem of radio-frequency contact.
To achieve the goals above, the invention discloses a kind of aerial mounting structure, including mainboard, first antenna elastic slice,
Second antenna shrapnel, radio frequency main body and connection antenna, first antenna elastic slice are connected electrically on mainboard, and the second antenna shrapnel is riveted on
In radio frequency main body, pass through connection antenna electrical connection between first antenna elastic slice and the second antenna shrapnel.
A kind of mobile terminal is also disclosed, including above-mentioned aerial mounting structure.
It can be seen from the above technical proposal that the aerial mounting structure of the embodiment of the present invention, in radio frequency main body and antenna flicking
It is fixed between piece by riveting, so that the radio-frequency contact point between antenna shrapnel and radio frequency main body is not perishable and falls off,
And connection structure is reliable and stable, and process structure is simpler, is easier to realize, can effectively improve the reliability of radio-frequency contact.
