ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an improved antenna connector of a cellular phone and, more particularly, to a connector facilitating the connection of a signal adapting wire and a cellular phone.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, an antenna
10
of a cellular phone in prior art comprises a sleeve spindle
11
, a base
12
, and a compression spring
13
. The base
12
is received in the sleeve spindle
11
. The bottom end of the base
12
protrudes out of the sleeve spindle
11
to form a plugging shaft
14
to be plugged in the cellular phone. The compression spring
13
is received in the sleeve spindle
11
and can be used as a conductor for telephone signals. The bottom end of the compression spring
13
contacts with the base
12
.
When the cellular phone is used in a car, a signal adapting wire of the cellular phone is generally connected to an antenna installed on the car to avoid noise interference so as to acquire better transmission quality. In prior art, when the signal adapting wire of a cellular phone is used, the detachable antenna of the cellular phone needs to be detached first, and a connector of the signal adapting wire is then plugged in the cellular phone. Next, a connector at the other end of the signal adapting wire is plugged in a connection seat of the car antenna. Through the connection of the cellular phone and the car antenna via the signal adapting wire, noise interference can be prevented when the cellular phone is used in the car. Moreover, transmission quality will be better because there is less landform interference.
However, for the antenna of the cellular phone in prior art, when the signal adapting wire is to be connected, the detachable antenna of the cellular phone needs to be detached first so that a connector of the signal adapting wire can then be plugged in the cellular phone. Because the antenna of the cellular phone is a delicate component, constant detaching and plugging result in a trouble, and destruction of the antenna may easily arise. Moreover, the antenna with a small volume may be easily lost after detached from the cellular phone, resulting in a great problem to the user.
SUMMARY AND OBJECTS OF THE PRESENT INVENTION
The primary object of the present invention is to provide an improved antenna connector of a cellular phone, wherein a plugging hole is disposed on the top end of a sleeve spindle of an antenna so that a first connector at one end of a signal adapting wire can be plugged therein. The first connector can penetrate into a compression spring of the antenna and contact with the compression spring so that the signal adapting wire can connect the cellular phone to a car antenna. The present invention can directly plug the first connector of the signal adapting wire in the antenna. The antenna of the cellular phone needs not to be detached so that constant detaching and plugging of the antenna is not required. Easy and convenient use can thus be achieved. Destruction of the antenna and the possibility that the antenna is lost can also be effectively avoided. Moreover, the structure of the present invention is very simple so that production cost can be greatly reduced.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings, in which:
