PURPOSE:To provide a relay device having no metal sheath and a large shielding effect by molding a printed board connecting the core wires of a shield cable and a pair of shield boards pinching the printed board for electrical connection. CONSTITUTION:Core wires 5a of a multi-core shield cable 5 and core wires 6a of multiple single-core shield cables 6 are soldered to the conducting layer of a printed board 5 for electrical connection. The printed board 1 is overlapped on a shield board 2, conducting poles 4 having insulating spacers are inserted into through holes provided at four corners of the printed board 1 and the shield boards 2, 3, they are soldered to solid conducting layers 2a, 3a of the shield boards 2, 3 to electrically connect them and to restrict the interval between the boards 1, 3. Shield sections 5b, 6b of the cables 5, 6 are soldered to the solid conducting layer 3a of the shield board 3, and the whole boards 1-3 are molded with plastic. A cable relay device having no metal sheath and a large shielding effect can be provided. |
