PURPOSE:To simplify the structure of a printed board by providing a first contact group provided on a connector body and connected to a first printed wiring on the surface side of the printed board, and a second contact group connected to a second printed wiring on the back side. CONSTITUTION:A printed board 4 having printed wirings 8, 8', a connector body 3 installed on a part of the surface of the board 4, and a first line contact group 1 provided on the body 3 and connected to the surface side wiring 8 are provided. A second line contact group 2 connected to the back side wiring 8' is also provided. Hence, the contact group 1 is connected only to the wiring 8 through a contact connecting pad 6, and all of the contact group 2 is connected only to the wiring 8'. Thus, the numbers of contact insert holes 5 and contact connecting lands 7 can be suppressed to the minimum. As the wirings 8, 8' are straightly pattern-printed, their thicknesses can be sufficiently increased, and a margin for the electric capacity of a signal can be provided. |
