         [0003]    2. Description of Related Art 
         [0004]    TW patent No. 239609 issued to Huang on Jan. 21, 1995 discloses an electrical connector. The electrical connector includes a first connector and a second connector interconnected each other via plurality of wires. The wires with opposite ends thereof are soldered to corresponding contacts of the first connector and the second connector, respectively. The electrical connector may result in lower productive efficiency and higher productive cost. With development of an electronic development, the aforementioned electrical connector is unable to meet complex and powerful function requirement. So an improved electrical connector (adaptor) is emerged in the market. The adaptor includes a first connector and a second connector connected together via a printed circuit board, and some other electronic elements, IC chip, resistor, capacitor etc. are also mounted to the printed circuit board. However ever, those electronic elements are delicate and unable to bear high thermal environment and easily to be damaged. 
         [0005]    Hence, an improved electrical connector is highly desired to overcome the disadvantages of the related art. 
       SUMMARY OF THE INVENTION 
       [0006]    Accordingly, an object of the present invention is to provide a shielded electrical connector. 
         [0007]    In order to achieve the object set forth, an electrical connector in accordance with the present invention comprises a first connector and a second connector electrically connected together by a printed circuit board assembly; a tubular shaped first shielding member enclosing the printed circuit board assembly, partial of the first and second connector; a second shielding member assembled to first shielding member and retaining the first connector and the second connector. 
         [0008]    Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
