Description

  The present invention relates to an endoscope connector connected to a receptacle unit.

  In general, an endoscope has a universal cord. This universal cord has a connector (connecting portion) for connecting to the receptacle unit. The receptacle unit is, for example, a video processor or a light source device having an opening into which a connector is inserted. This opening is called, for example, a socket or a receptacle.

For example, Patent Document 1 discloses an endoscope that can continue to illuminate a subject with a light amount suitable for observation.
In this endoscope connector, the connector includes a connector gripping portion gripped by an operator, and a connector main body portion disposed closer to the receptacle unit than the connector gripping portion. The central axis of the connector gripping part and the central axis of the connector main body part are coaxial.

  The connector body has one end and the other end. By connecting the end of the connector gripping portion and one end of the connector main body portion, the connector gripping portion and the connector main body portion are integrated. The other end of the connector main body has a terminal portion connected to the receptacle unit. Generally, in a state where the connector gripping portion is gripped by the operator, the connector main body including the terminal portion is pushed (inserted) into the opening of the receptacle unit. As a result, the connector (terminal portion) is connected to the receptacle unit.

  The receptacle unit has an engaging portion such as a lever that engages with the connector main body when the connector main body is inserted into the receptacle unit. Further, the connector main body portion has an engaged portion such as a protruding portion with which the engaging portion engages on the upper surface of the connector main body portion. The engaged portion is disposed on the central axis of the connector main body.
