PROBLEM TO BE SOLVED: To provide a signal connector device preventing poor contact in a connected state and reducing a connection force by weakening a frictional force between a contact pin and a contact tube when connecting a signal connector to a signal connector receiver.SOLUTION: When a signal connector 11 is connected to a signal connector receiver 21, a perforated plate 30 in the side of the signal connector receiver 21 is pushed in against an urging force of an urging means 33 by a perforated plate driving member 14 provided in the signal connector 11. Then, a tapered portion 28 of each contact tube 25 provided in the signal connector receiver 21 is pushed radially by a tube diameter control hole 31 of the perforated plate 30 to be narrowed from the distal end side, and the internal periphery part 26 of each contact tube 25 comes into close contact with each contact pin 15 on the side of the signal connector 11.COPYRIGHT: (C)2013,JPO&INPIT【課題】信号コネクタと信号コネクタ受けとの接続動作時に接点ピンと接点筒との擦れ合いの力を弱めることにより、接続状態時の接触不良が発生せず、また接続力量を軽減することができる内視鏡の信号コネクタ装置を提供すること。【解決手段】信号コネクタ11が信号コネクタ21受けに接続されると、信号コネクタ11に設けられた多孔板駆動部材14により信号コネクタ受け21側の多孔板30が付勢手段33の付勢力に抗して押し込まれることにより、信号コネクタ受け21に設けられた各接点筒25のテーパ状部分28が多孔板30の筒径制御孔31により径方向に押されて先端側から搾まり、それによって各接点筒25の内周部26が信号コネクタ11側の各接点ピン15と密接される。【選択図】 図1
