Abstract
The utility model relates to a small-size mobile television terminal external antenna. The external antenna comprises a pull-rod assembly, a fixed seat, an antenna cap and a rotating shaft, wherein two ends of the pull-rod assembly are provided with the antenna cap and the rotating shaft. The lower end of the rotating shaft is inserted into the fixed seat; a drum spring is positioned inside the fixed seat and sleeved on the rotating shaft. The 360-degree rotation of the rotating shaft inside the fixed seat is realized by abutting against the inner wall of the fixed seat and the outer wall of the rotating shaft. A contacting spring piece is arranged outside the fixed seat and is in conductive connection with feed points on a printed circuit board (PCB) inside a mobile terminal. The diameter of the rotating shaft is smaller than that of the pull-rod assembly, and the size of the fixed seat is corresponding to that of the rotating shaft. The external antenna has small volume and compact structure. Through a method of using the external antenna, the difficulty of design of the pull-rod assembly is reduced, the pull-rod antenna performance is ensured, and the cost is reduced. The rotating shaft is only connected with the fixed seat in the structure of the external antenna, the sizes of the rotating shaft and the fixed seat can be reduced, thereby providing more space for the mobile terminal and benefiting miniaturization of the mobile terminal.
Description
Technical field
The utility model relates to telescopic antenna, is specifically related to a kind of antenna that is applicable to the Miniature Terminal product.
Background technology
At present, be used for the telescopic antenna of Miniature Terminal (as network interface card, mobile phone etc.), because the Miniature Terminal volume is little, the inner space deficiency, telescopic antenna partly has only end and terminal to be connected and fixed, and the telescopic antenna body is not need to take in terminal inner.But, bigger if telescopic antenna and terminal are connected and fixed the size of part, also can bigger space, occupied terminal inside, thus make the terminal volume can't miniaturization.Because the miniaturization demand of terminal is more and more higher, and also more and more higher to the telescopic antenna performance demands, caused the telescopic antenna of this type of Miniature Terminal, R﹠D process is difficulty relatively, the R﹠D and production cost is higher, and the size of telescopic antenna, complexity, cost become the focus of contradiction.
Summary of the invention
The problem that the utility model need solve provides a kind of miniaturization, mobile TV terminal antenna that cost is low.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of small-sized mobile TV terminal external antenna is provided, comprise rod assembly, holder and be located at the antenna cap and the rotating shaft at rod assembly two ends, insert in the holder described rotating shaft lower end, be provided with bulging spring in the described holder, the drum spring is socketed in the rotating shaft, props up holder inwall and rotating shaft outer wall and realizes that rotating shaft is in the inner 360 degree rotations of holder; Also be provided with contact flat spring outside holder, the feedback point in this contact flat spring and the portable terminal on the pcb board is connected conducting.
Further, described rotating shaft diameter is less than the rod assembly diameter, and holder size and rotating shaft are suitable.
Concrete, described rotating shaft comprises rotating shaft, lower rotary shaft and is used to connect the roller pin of the two.
Concrete, described rod assembly comprises the stainless steel tube of the mutual socket of more piece, adopts the cydariform shell fragment to connect between each stainless steel tube, and each mouth of pipe junction also is provided with back-up ring, is provided with nitinol alloy wire in it, and described nitinol alloy wire is connected with antenna cap.
Preferably, described holder outer wall is provided with draw-in groove, and contact flat spring is installed in the draw-in groove.
Preferably, described antenna cap is ferrous material or magnet antenna cap, and the portable terminal corresponding position is established and is used for and its magnet that adsorbs mutually or iron.
Compared with prior art, the utlity model has following advantage:
(1) described antenna volume is little, and compact conformation adopts the external mode of antenna, has simplified the design difficulty of rod assembly, has guaranteed the telescopic antenna performance, has reduced cost;
(2) have only rotating shaft to be connected, can dwindle rotating shaft and holder size,, be beneficial to the miniaturization of portable terminal for portable terminal provides more spaces with holder;
(3) described antenna cap adopts magnetic material or iron work, but only need install just positioning antenna cap of ironwork magnetisable material in the terminal inner relevant position additional, and folding and unfolding is easy to use flexibly;

Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing.
As Figure 1-3, the small-sized mobile TV terminal external antenna that the utility model disclosed comprises antenna cap 1, rod assembly 2, rotating shaft 3, holder 4.Described antenna cap 1 is located at rod assembly 2 tops, and rotating shaft 3 is located at rod assembly 2 lower ends, and holder 4 is arranged on the portable terminal, and rotating shaft 3 is inserted in the holder 4.Be provided with bulging spring 5 in the holder, drum spring 5 is socketed in the rotating shaft 3, and it props up holder 4 inwalls and rotating shaft 3 outer walls, and rotating shaft and holder are flexibly connected, and rotating shaft can be rotated at inner 360 degree of holder, makes the direction 360 of telescopic antenna adjustable.Be provided with draw-in groove 41 on holder 4 outer walls, contact flat spring 6 is set in the draw-in groove 41, this contact flat spring is connected conducting with feedback point on the pcb board in telescopic antenna and the portable terminal.
Wherein, rod assembly 2 comprises the stainless steel tube 21 of the mutual socket of more piece, adopts lantern spring 22 to connect between each stainless steel tube, and each mouth of pipe junction also is provided with back-up ring 23, is provided with nitinol alloy wire 24 in it, and described nitinol alloy wire is connected with antenna cap.Here lantern spring 22 also can adopt the cydariform shell fragment to substitute.Antenna cap 1 adopts ferrous material to make, and can be held by the carrying magnetic object, and the telescopic antenna upper end relies on the absorption of antenna cap to be fixed on the portable terminal like this.
Described rotating shaft 3 comprises rotating shaft 31, lower rotary shaft 32, roller pin 33, last rotating shaft can about 180 degree swings, 0 ~ 180 degree position stops arbitrarily, guarantees the flexibility that the telescopic antenna direction is adjusted.
The rotating shaft diameter L2 that designs in the utility model is less than rod assembly L1 diameter, and corresponding diameter with the holder 4 rotating shaft socket also can dwindle.Because described antenna is an external, rod assembly does not need to take in the holder, employing is than the rotating shaft of minor diameter, just can fully reduce the volume that is arranged on the holder on the portable terminal, rotating shaft one end connects the rod assembly of big outside dimension, and the other end connects undersized holder, has reduced the rod assembly design difficulty, when having guaranteed antenna performance, make the abundant miniaturization of portable terminal.
Foregoing is preferred embodiment of the present utility model only, is not to be used to limit embodiment of the present invention, and those skilled in the art are according to design of the present invention, and appropriate adaptation of having done or modification all should be within protection scope of the present invention.
