Connector for medical instrument

A connector for a medical instrument connected to an external device for medical use, the connector comprising:

• a plug portion in which a plurality of electric contact point portions to the external device are placed;
• an outer sheath case connectively provided as a separate piece at the plug portion;
• a sub frame member interposed between the plug portion and the outer sheath case, and having a flange portion which abuts on respective end portions of the plug portion and the outer sheath case;
• a main frame member housed in the outer sheath case and fixed to the sub frame member;
• a first fixing member configured to fix the outer sheath case to the main frame member by fastening such that the outer sheath case is pressed in a longitudinal axis direction of the main frame member;
• and
• a second fixing member configured to fasten the plug portion to the flange portion,
• wherein:
• the outer sheath case receives reaction force to compression force generated in the longitudinal direction of the main frame member by being butted against the flange portion by fastening of the first fixing member and is fixed to the main frame member and the sub frame member in a state in which the outer sheath case is compressed, and
• the plug portion receives pressure generated by being butted against the flange portion by fastening of the second fixing member and fixed to the sub frame member in a state in which the plug portion is compressed.
