Abstract
The utility model relates to a mobile phone antenna which comprises a revolving shaft, a retractable stainless steel tube and a memory alloy wire, wherein one end of the retractable stainless steel tube is connected with the revolving shaft and the other end thereof is connected with the memory alloy wire; the outer diameter of the retractable stainless steel tube is less than 2.2mm. Compared with the prior art, the mobile phone antenna has the advantages of small occupied space, simple processing and the like.
Description
Technical field
The present invention relates to a kind of antenna, especially relate to a kind of little antenna for mobile phone in space that occupies.
Background technology
Arriving along with the mobile communication epoch, mobile phone has become the individual and has carried, used one of indispensable communication articles for use, wherein antenna for mobile phone is to realize that mobile phone and communication base station carry out the interface of wireless data exchange, thereby the quality of antenna becomes the important indicator of cell-phone function.The antenna for mobile phone of comparative maturity has external antenna and Metal Flake built-in aerial at present.
Traditional external antenna comprises metallic object, metal terminal and plastic shell composition, wherein metallic object is effective antenna emission and receiving device, this metallic object has determined the performance characteristics of antenna, conventional antenna maximum outside diameter is generally 2.2mm, 3 joints can be set at most, therefore, the length of every joint that can only extend, just can satisfy the demand, it is bigger to take up room.
Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of take up room little, process simple antenna for mobile phone.
Purpose of the present invention can be achieved through the following technical solutions: a kind of antenna for mobile phone, it is characterized in that, this antenna comprises rotating shaft, scalable stainless steel tube and memorial alloy line, described scalable stainless steel tube one end connects rotating shaft, the other end connects the memorial alloy line, and the external diameter of scalable stainless steel tube is less than 2.2mm.
Described scalable stainless steel tube comprises first stainless steel tube, second stainless steel tube and the 3rd stainless steel tube 3 joints, described first stainless steel tube connects rotating shaft, the described second stainless steel tube two ends connect first stainless steel tube and the 3rd stainless steel tube by the drum spring respectively, and described the 3rd stainless steel tube connects the memorial alloy line by the drum spring.
But in the described second stainless steel tube retraction, first stainless steel tube, but described the 3rd stainless steel tube retraction second stainless steel tube, but in described memorial alloy line retraction the 3rd stainless steel tube.
Described rotating shaft connects scalable stainless steel tube by shaft joint, is provided with spring and stainless shot between described rotating shaft and the shaft joint.
In rotating shaft, the other end and scalable stainless steel tube are spirally connected described shaft joint one end by dowel fixes.
Rotating shaft and shaft joint can use technologies such as MIM sintering and fine finishining.
Compared with prior art, antenna of the present invention adopts less scalable stainless steel tube and the NITI line of external diameter, make antenna be telescopic 4 joints, in diametric(al), the short transverse that is mobile terminal device can be saved very big space, the rotating shaft of weapons antenna and shaft joint can use traditional handicrafts such as MIM sintering and fine finishining, and method is simple.
Description of drawings
Fig. 1 is the structural representation of antenna of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
A kind of antenna for mobile phone, this antenna comprise rotating shaft 1, scalable stainless steel tube and memorial alloy line 5, and described scalable stainless steel tube one end connects rotating shaft, and the other end connects the memorial alloy line, and the external diameter of scalable stainless steel tube is less than 2.2mm.Described rotating shaft 1 connects scalable stainless steel tube by shaft joint 7, be provided with spring 8 and stainless shot 9 between described rotating shaft 1 and the shaft joint 7, described shaft joint 7 one ends are fixed in the rotating shaft 1 by pin 10, the other end and scalable stainless steel tube are spirally connected, and rotating shaft and shaft joint can use technologies such as MIM sintering and fine finishining.
Described scalable stainless steel tube comprises 3 joints such as first stainless steel tube 2, second stainless steel tube 3 and the 3rd stainless steel tube 4, described first stainless steel tube 2 connects rotating shaft 1, described second stainless steel tube 2 two ends connect first stainless steel tube 2 and the 3rd stainless steel tube 4 by drum spring 6, drum spring 11 respectively, and described the 3rd stainless steel 4 pipes connect memorial alloy line (NITI line) 5 by drum spring 12.But in described second stainless steel tube, 3 retractions, first stainless steel tube 2, but described the 3rd stainless steel tube 4 retractions second stainless steel tube 3, but in described memorial alloy line 5 retractions the 3rd stainless steel tube 4, wherein the external diameter of first stainless steel tube 2 is 2.0mm to the maximum, the external diameter of second stainless steel tube 3, the 3rd stainless steel tube 4 and NITI line 5 reduces successively, with convenient flexible, and the telescoping tube joint number increase of antenna can reduce its diametric length when shrinking, thereby saves the space.
