Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a battery connector, more particularly to a battery connector for handset or portable electrical device. 
         [0003]    2. Description of Prior Arts 
         [0004]    In normal electronic devices, such as a cell phone, usually uses a battery connector to provide an electrical connection between one of the electronic devices and a battery. 
         [0005]    The  FIG. 1  discloses a conventional battery connector  100 ′, comprising an insulative housing  1 ′, a plurality of contacts  2 ′ and a metal cover  3 ′. The metal cover  3 ′ includes a main portion (not marked), side wings which bending and extending forward from two sides of the main portion, and fix portion  33 ′ which bending and extending outward from the side wings  32 ′; the insulative housing including a top wall  11 ′, a front wall  12 ′, a first sidewall  13 ′ and a second sidewall  14 ′, a sunken portion  111 ′ is formed which is corresponding to the main portion and the side wings  32 ′ of the insulative housing  1 ′. Installing the metal cover  3 ′ in the sunken portion  111 ′, the retention between the battery connector  100 ′ and the printed circuit board can be strengthened by soldering of the fix portion  33 ′ and the printed circuit board. However, after installing the contacts  2 ′ in the insulative housing  1 ′, there is no element attached to the front wall  12 ′ can be used to block the contact  2 ′. Therefore, it will be easy for the contact  2 ′ to drop off the insulative housing  1 ′ 
         [0006]    Hence, an improved battery connector is desired to overcome the disadvantages and problems of the prior art.
