         [0004]    Although the above two prior arts provide sockets for USB connectors and has sockets for SATA connectors for high-speed transmissions, modern requirements for transmission speed is getting crucial and a new protocol for high-speed transmission has appeared which is not covered by the above prior arts. Hence, the prior arts do not fulfill users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0005]    The main purpose of the present invention is to integrate an RJ45 connector, a USB connector and an eSATA connector into a single structure to save space, to obtain hot-swapping, and to provide an increased transmission speed. 
         [0006]    To achieve the above purpose, the present invention is a three-in-one connector set, comprising a substrate having a circuit board and a wave filter; a first connector of an RJ45 connector; a second connector together with a third connector separately being a USB connector and an eSATA connector; and a metal shell being coated at outside of the substrate, the first connector, the second connector and the third connector, where the first connector has a first shell, a first set of terminals and a set of external terminals; the first shell is fixed-on the circuit board and has a socket; the first set of terminals is set in the socket and is electrically connected with the circuit board; the set of external terminals is electrically connected with the circuit board and is connected with the substrate; the second connector together with the third connector has a second shell and a second set of terminals together with a third set of terminals; the second shell is fixed on the circuit board and has two socket; the second set of terminals together with the third set of terminals is separately set in the two sockets and is electrically connected with the circuit board and is connected with the substrate at an end; and the metal shell has openings corresponding to sockets for the first connector, the second connector, and the third connector. Accordingly, a novel three-in-one connector set is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0011]    The following description of the preferred embodiment is provided to understand the features and the structures of the present invention. 
         [0012]    Please refer to  FIG. 1  and  FIG. 2 , which are a front view and an explosive view showing a preferred embodiment according to the present invention. As shown in the figures, the present invention is a three-in-one connector set, comprising a substrate  1 , a first connector  2 , a second connector  31  together with a third connector  32 , and a metal shell  4 . 
         [0013]    The substrate  1  has a circuit board  11 , where the circuit board  11  has a wave filter  12  and an indicator  13 . 
         [0014]    The first connector  2  has a first shell  21 , a first set of terminals  22  and a set of external terminals  23 , where the first shell  21  is fixed on the circuit board  11  and has a socket  211 ; the first set of terminals  22  is set in the socket  211  and is electrically connected with the circuit board  11 ; the set of external terminals  23  is electrically connected with the circuit board  11  and is connected with the substrate  1 ; and the first connector  2  is an RJ45 (Registered Jack 45) network connector. 
         [0015]    The second connector  31  together with the third connector  32  has a second shell  30  and a second set of terminals  312  together with a third set of terminals  322 , where the second shell  30  is fixed on the circuit board  11  and has two sockets  311 , 321 ; the second set of terminals  312  together with the third set of terminals  322  is separately set in the two sockets  311 , 321  and is electrically connected with the circuit board  11  and is connected with the substrate  1  at an end; and the second connector  31  together with the third connector  32  is separately a Universal Serial Bus (USB) connector and an external Serial Advanced Technology Attachment (eSATA) connector. Therein, the second connector  31  is piled up on the third connector  32 ; or, on the contrary, the third connector  32  is piled up on the second connector  31  (not shown in the figures).
