PURPOSE:To make easy for alignment of photo emitting and detecting elements, by providing the holding projection section for the light source of trigger such as photo emitting element to control the semiconductor element and output terminals of optical fiber with the inside wall of the insulation enslosure sealing thyistors together with the lower electrode, and to increase the photo coupling efficiency. CONSTITUTION:The projection 22 having the metal chip 23 fixed with silver solder on the upper surface is formed on a given location of the inside wall of the hollow insulation cylinder 19 having heat dissipation fin at external. Next, the light emitting diode consisting of the header 25, GaSa chip 26 and electrode terminal 27 is mounted on th metal chip 23, and the light emitting terminal and the terminal 29 are provided through the cylinder 19. Thus, the dish electrodes 13 and 14 clipping the thyristor 12 of PNPN 4 layer construction are inserted in th cylinder 19 and after depressing and holding thrusts 20 and 21 being a pair of copper up and down electrodes, the thrusts 20 and 21 are fixed at the both ends 17, 18 of the cylinder 19 by using the rimbs 15 and 16 of the terminal material. |
