Disclosed are a connector (500) and an endoscope system. The connector (500) is applied to the endoscope system. The endoscope system comprises: an endoscope (100), and a light source device (200) and/or a processor device (300) detachably connected to the endoscope (100), the connector (500) being arranged between the endoscope (100) and the light source device (200) and/or the processor device (300) to establish a connection between the endoscope (100) and the light source device (200) and/or the processor device (300). The connector (500) comprises: a plug (510) arranged at one end of the endoscope (100), and a socket (520) arranged on the light source device (200) and/or the processor device (300) and fitted with the plug (510). A fixed terminal (511) is provided at an end of the plug (510), and a movable terminal (521) fitting with the fixed terminal (511) is provided on the corresponding position of the socket (520). When the plug (510) is in plug-connection with the socket (520), end-face abutting is realized between the fixed terminal (511) and the movable terminal (521). The connector (500) and the endoscope system solve the problem of being unable to transmit control signals and/or image signals between the plug (510) and the socket (520).Linvention concerne un connecteur (500) et un système endoscope.
