PROBLEM TO BE SOLVED: To secure connection strength of exterior members without being restricted by a size or a shape in a connector for an ultrasonic signal of an ultrasonic endoscope.SOLUTION: A connector for an ultrasonic signal of an ultrasonic endoscope includes: a circuit board to which an ultrasonic signal cable is connected an internal frame for supporting the circuit board a connection part connected to an ultrasonic observation device to allow an ultrasonic signal to be transmitted/received to and from the circuit board a first exterior member and a second exterior member combined with each other in a watertight state, forming an internal space for housing the internal frame and the circuit board, which are connected to the internal frame by fixing means respectively and an auxiliary connection member provided separately from the fixing means for connecting a frame connection part to the internal frame, and connecting an exterior member connection part to either the first exterior member or the second exterior member so as to regulate a relative movement in a separation direction of the first exterior member and the second exterior member.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2018,JPO&INPIT【課題】超音波内視鏡の超音波信号用コネクタで、大きさや形状による制約を受けずに外装部材の結合強度を確保する。【解決手段】超音波信号ケーブルが接続する回路基板と、回路基板を支持する内部フレームと、超音波観測装置に接続して回路基板との間で超音波信号を送受可能にする接続部と、互いの間を水密状態にして組み合わされて内部フレーム及び回路基板を収容する内部空間を形成し、内部フレームに対してそれぞれ固定手段によって固定される第1の外装部材及び第2の外装部材と、固定手段とは別に設けられ、内部フレームに対してフレーム結合部を結合させると共に第1の外装部材と第2の外装部材のいずれかに対して外装部材結合部を結合させて、第1の外装部材と第2の外装部材の分離方向の相対移動を規制する補助結合部材とによって超音波信号用コネクタを構成した。【選択図】図12
