Lead wire connection structure for air-cooled optoelectric transducer

Abstract

Abstract PURPOSE:To improve working efficiency in connecting lead wires by a structure wherein contact electrodes corresponding to radial leads of an air-tight tubular body are provided on an insulative substrate having an opening through which the tubular body is inserted, and elastic pieces for pressing the lead wires are also provided thereon. CONSTITUTION:An insertion opening 12, through which an air-tight tubular body including an optoelectric transducer is inserted and enclosed therein, is formed at the center of a first insulative substrate 11, and contact electrodes 13 are disposed at positions corresponding to radial lead wires 3 fixed to a ceramic substrate 4 of the body. (14 denotes lead-out wires and 15 denotes shield electrodes). Then, a second insulative substrate having cutouts at positions corresponding to the contact electrodes 13 and a third insulative substrate having elastic pieces for pressing the lead wires are provided thereby to constitute a lead wire connection structure for an air-cooled optoelectric transducer. By so doing, working efficiency in connecting the lead wires is improved and reliability in connections is also improved.
