The fixture and the portable terminal thereof that are used for the ATV/DTV telescopic antennaTechnical field
The present invention relates to a kind of fixture of telescopic antenna and comprise its portable terminal, particularly relate to a kind of for the ATV(anolog TV signals)/the DTV(digital television signal) telescopic antenna fixture and comprise its portable terminal.
Background technology
The fixed form that is used at present the ATV/DTV telescopic antenna perforation that normally fixes in the shell on the back middle part of portable terminal is inserted a plastic cement sleeve in this perforation earlier during assembling, and then the installation telescopic antenna.In addition, the earthing mode that is used for the ATV/DTV telescopic antenna at present is that hot melt increases a metal grounding elastic part on the shell on the back of portable terminal, contacts ground connection with telescopic antenna, need newly open a mold for this reason.
The problem that above-mentioned prior art exists is:
1, the shell on the back of portable terminal is diminished its secondary appearance by holes.
2, need newly open a mold for the metal grounding elastic part, increase production cost.
3, the metal grounding elastic part is not tight with contacting of telescopic antenna, and the ground connection reliability is bad.
4, earthing device separates with fixture, increases production cost.
Therefore, expect the telescopic antenna fixture that comprises grounding function that a kind of mould is more simplified, ground connection is more reliable, the shell on the back outward appearance is more attractive in appearance, cost performance is higher.
Summary of the invention
For the high and unstable problem of ground connection of fixture cost that solves telescopic antenna among the present invention better, a kind of fixture for the ATV/DTV telescopic antenna now is provided and comprises its portable terminal.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of fixture for the ATV/DTV telescopic antenna, it comprises that one is fixed in the radome of a portable terminal fore shell, its characteristics are, this radome has the outstanding fixed part that stretches out, when the shell on the back of this portable terminal fore shell and this portable terminal fastened, this fixed part compressed the telescopic antenna on the shell on the back of this portable terminal.So to realize the effect of steady brace antenna.
Preferably, this fixed part is provided with a grounding elastic part, and when the shell on the back of this portable terminal fore shell and this portable terminal fastened, this grounding elastic part contacted with this telescopic antenna.Because the electromotive force of radome itself is ground, so can realize making the effect of telescopic antenna ground connection this moment.
Preferably, this grounding elastic part is made by electric conducting material, as metal material commonly used.
Preferably, this grounding elastic part is triangular hill shape or arc convex shape.So the grounding elastic part of shape can guarantee that this grounding elastic part fully contacts with this telescopic antenna is sure when this portable terminal fore shell and shell on the back fastening.
Preferably, this fixed part is shaped as frame.This fixed part can also be other constitutionally stable shape, as parallelogram, and triangle etc.
Preferably, this radome is formed in one with this fixed part or fixedlys connected.
The present invention also provides a kind of portable terminal, comprises that a shell on the back and is arranged at the telescopic antenna on this shell on the back, and its characteristics are that it comprises aforesaid fixture for the ATV/DTV telescopic antenna.
Preferably, this shell on the back is provided with some ribs, and this rib is positioned at the both sides of this telescopic antenna, in its length direction vertical distribution, limits effect that this telescopic antenna move to play around telescopic antenna.
Preferably, this telescopic antenna locks on this shell on the back by several screws.
Positive progressive effect of the present invention is:
1, simplifies the mould of making this portable terminal shell on the back, saved some and be used for perforation and the annex of steady brace antenna, saved cost, be convenient to assembling simultaneously, beautified outward appearance.
2, saved hot melt ground connection metal clips on the portable terminal shell on the back, and realized the function of ground connection in the steady brace antenna, globality is strong, and is useful to complete machine static.

Embodiment
Mode below by embodiment further specifies the present invention, but does not therefore limit the present invention among the described scope of embodiments.
The present invention is used for the fixture of ATV/DTV telescopic antenna, its mainly by the shell on theback 5 of atelescopic antenna 4, one portableterminal fore shells 6, one portable terminals, aradome 1 and on afixed part 2 and a grounding elastic part 3 form.
With reference to figure 1 and Fig. 2, introduced a kind of preferred embodiment of the present invention, oneradome 1 is fixed on the portableterminal fore shell 6, thisradome 1 has the outstandingfixed part 2 that stretches out, and bearing of trend is corresponding to the position of thetelescopic antenna 4 on the shell on theback 5 that is positioned at this portable terminal when this portable terminal assembling.When the shell on theback 5 of this portableterminal fore shell 6 and this portable terminal fastened, thisfixed part 2 compressed thetelescopic antenna 4 on the shell on theback 5 of this portable terminal, to realize the effect of steady brace antenna.Thisfixed part 2 is preferably shaped as frame, to keep Stability Analysis of Structures.Certainly, the structure of this fixed part is not limited to shaped as frame herein, and it can also other has the shape of rock-steady structure for parallelogram, triangle etc.Thisradome 1 is formed in one with thisfixed part 2 or fixedlys connected.
Further, thisfixed part 2 is provided with a grounding elastic part 3, and when the shell on theback 5 of this portableterminal fore shell 6 and this portable terminal fastened, this grounding elastic part 3 contacted with thistelescopic antenna 4, becauseradome 1 electromotive force own is ground, can realize making the effect oftelescopic antenna 4 ground connection this moment.This grounding elastic part 3 is made by electric conducting material, as metal materials such as iron commonly used, aluminium.This grounding elastic part 3 is triangular hill shape or arc convex shape, and guaranteeing when the shell on theback 5 of this portable terminal foreshell 6 and this portable terminal fastens, this grounding elastic part 3 and thistelescopic antenna 4 are sure fully to be contacted.This grounding elastic part 3 can be integrated with thisradome 1 or thisfixed part 2, also can be fixedly connected.
As shown in Figure 3, when this portable terminal assembling, the present invention only needs portableterminal fore shell 6 andback cover 5 are fastened, at this moment, fixedpart 2 on thefore shell 6 compresses thetelescopic antenna 4 on shell on theback 5 relative positions, plays fixation, and grounding elastic part 3 fully contacts with thistelescopic antenna 4 and is grounded.Advantage of the present invention is, need not additionally bore a hole and increase parts, only need utilize the wider space of radome, has realized steady brace antenna and the function that makes its ground connection simultaneously.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention has appended claims to limit.Those skilled in the art can make numerous variations or modification to these execution modes under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
