ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a simplified helical antenna structure for communication equipment, and especially to an antenna which is extensible directly to electrically connect with an electric circuit board inside of a machine body for simplifying components.
2. Description of the Prior Art
A helix antenna of which the spiral coil is formed by winding metallic wires is the major type of antenna. Helix antenna of such structure will affect the set function in every aspect. Such as the helix antenna disclosed in British patent No. 2,206,243, it decides the proper function of the whole helix antenna by the factors including the diameter or the material of the wires of a helix coil or the pitch between rings of the helix coil or the overall length of the helix coil of the helix antenna.
FIG. 1
shows a fixed miniature antenna of a mobile phone, it can be combined on the top of the mobile phone in a snap-in mode. Basically, such a fixed miniature antenna of a mobile phone is provided generally in the interior of an external insulating sleeve
10
thereof (namely, the exposed pipe of the antenna) with an internal insulating sleeve
11
for positioning therein a metallic receiving seat
12
. A top surface
13
of the metallic receiving seat
12
is mounted thereon a coil
15
to cooperate with the inner upper surface
14
of the external insulating sleeve
10
; while a lower portion
16
thereof can be mounted thereon a partially exposed elastic contact piece
17
. The elastic contact piece
17
is used to electrically connect with a reserved antenna line of an electric circuit board inside of the mobile phone. But the defect of such conventional helix antenna resides in that, an additional kind of material is required to form the elastic contact piece
17
, and an additional assembling process is required to connect the elastic contact piece
17
to the interior of the antenna, and thereby such assembling process is more troublesome and time consumptive.
SUMMARY OF INVENTION
An object of the present invention is to provide a simplified helical antenna structure for communication equipment, whereof, an inside spiral coil can be extended downwardly out of the antenna, and the exposed extension end thereof can be electrically connected with an electric circuit board inside of a mobile phone. In this way, an elastic contact piece and its related assembling process can be omitted, thus the internal structure of the antenna can be simplified. This is the primary motive of the present invention.
The present invention will be apparent in its novelty and other characteristics after reading the detailed description of the preferred embodiment thereof in refereference to the accompanying drawings. Wherein:
