Description
Technical field
Antenna technical field is the utility model is related to, more particularly, is related to a kind of antenna shrapnel, there is the antenna flicking
The housing of piece and the communication terminal with the housing.
Background technology
Due to metal material have unique gloss and sense of touch, hardness height, scratch resistance, it is resistance to the performance such as fall, more and more just
The housing that formula mobile communication terminal uses metal material is taken, and the shell of metal material is itself served as into reception and sends signal
Antenna.
In this case, multiple antenna feed points are generally set on shell side side, and use antenna shrapnel by aerial signal
It is transferred to the mainboard PCB of portable mobile communication terminal.At present, it is the antenna feed point of shell side and portable mobile communication is whole
The mode that the mainboard PCB at end is electrically connected generally has following two.
A kind of mode is the hole that screwed in metal shell side wall, and one end of antenna shrapnel is fastened into shell by screw
The side wall of body, the other end of antenna shrapnel is then welded to pcb board.The advantages of this connected mode is antenna shrapnel and metal
The connection of housing is than stronger.But there is also following shortcomings：(1) require that intermetallic composite coating is processed using Full-numerical-control, not only
High processing costs, and when metal shell is punch forming, can not realize that Full-numerical-control is processed due to thickness low LCL；(2) side
Wall adds screw hole, causes to process relatively difficult, limits surrounding structure moulding more, and high processing costs；(3) side wall is beaten
After screw hole, cause assembling difficult, assembly cost rises.
Another way is, using C-shaped antenna shrapnel, one end of C-shaped antenna shrapnel is welded to printed circuit board (PCB), the other end
Contacted with the feed point extruding of housing sidewall.During this conventional c shell fragment is installed, first the first end of C-shaped shell fragment is welded
It is connected on pcb board, then the pcb board with C-shaped shell fragment is installed in the procapsid of housing.Ideally, pcb board is installed
Afterwards, the contact at the second end of C-shaped shell fragment can touch the antenna feed point in metal shell side wall exactly.Using this connection
The advantages of mode is side feed point handling ease, and relatively convenient is assembled relative to the mode to screw.However, this connected mode
There is also problems：(1) due to first by multiple C-shaped shell fragment positioning weldings on pcb board, then again with metal shell side wall
Antenna feed point alignment, easily occur assembling off normal, cause the contact of antenna shrapnel can not be with the antenna in metal shell side wall
Feed point is accurately docked, so as to be affected greatly to antenna performance；(2) is required more to the sidewall thickness of metal shell；(3) antenna
Feed point position is dumb, not firm enough；(4) because the contact of C-shaped shell fragment and the side wall of metal shell are interference fitted, so that will
When pcb board is installed to procapsid, assembling is difficult.
