PURPOSE:To reduce transmission loss by fitting optical cables in the holes of a plurality of conductive securing members inserted through the inserting sections of a plurality of cable lead-in ports formed in the bottom board of housing and stopped thereto, then choking the inserting sections with shielding boards. CONSTITUTION:A plurality of cable lead-in ports 11 are formed in parallel through the bottom board 1a of housing 1. The cable lead-in port 11 comprises a wide cable inserting section 11b and a stop portion 11a on the side wall. A plurality (three in the figure) of a plurality of conductive securing members 14 having engaging grooves 14b are inserted through the inserting section 11b and engaged with the stop portion 11a. An optical cable 13 is inserted into the hole 14a of the securing member 14 and a plurality of connectors 13-2 for a plurality of strands 13-1 are connected with the connector 5-1 of a printed board 5. The inserting section 11b is choked with a shielding board 12 after the securing board 14 is inserted. By such arrangement, a small securing structure having low transmission loss can be realized. |
