Title: Wire extension device

Description:
BACKGROUND OF THE INVENTION  
       [0001] The present invention relates to a wire extension device. More particularly, the present invention relates to a wire extension device which combines a socket module and an ETHERNET module.  
       [0002] A conventional wire extension device has a socket module only. A data transmission of a network should be transmitted through a telephone cable. Even if two computers use the same conventional wire extension device, the data transmission of the network are still transmitted through the telephone cable.  
       SUMMARY OF THE INVENTION  
       [0003] An object of the present invention is to provide a wire extension device which combines a socket module and an ETHERNET module so that the wire extension device will become a network interface and a network socket. When two computers use the same wire extension device, a data transmission of a network will be transmitted through the ETHERNET module which has a high speed transmission electric wire.  
       [0004] When two computers use two wire extension devices, a data transmission of a network will be transmitted through a wire carrier wave method. 
     
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
     [0005]FIG. 1 is a schematic view of a wire extension device of a preferred embodiment in accordance with the present invention; and  
     [0006]FIG. 2 is a schematic view of two wire extension devices of a preferred embodiment in accordance with the present invention. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION  
     [0007] Referring to FIG. 1, a first wire extension device  1  comprises a socket module  11  and an ETHERNET module  12 .  
     [0008] The first wire extension device  1  is used as a transmission medium between a network and a source of electricity.  
     [0009] When a first computer PC 1  and a second computer PC 1  use the same wire extension device, a data transmission of a network will be transmitted through the ETHERNET module.  
     [0010] Referring to FIG. 2, a second wire extension device  1   a  comprises another socket module  11   a  and another ETHERNET module  12   a.    
     [0011] The second wire extension device  1   a  is used as a transmission medium between a network and a source of electricity.  
     [0012] When a third computer PC 3  uses the second wire extension device  1   a  and the first computer PC 1  uses the first wire extension device  1 , a data transmission of a network will be transmitted through a wire carrier wave method.  
     [0013] If the first computer PC 1  and the second computer PC 1  are personal computers and the third computer PC 3  is a notebook computer, the first computer PC 1  and the second computer PC 1  should use the first wire extension device  1  and the third computer PC 3  should use the second wire extension device  1   a . Then a data transmission between the first computer PC 1  and the third computer PC 3  will be transmitted through the wire carrier wave method.  
     [0014] Furthermore, the socket module  11  and the ETHERNET module  12  can be extended.  
     [0015] The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.
