Publication number: 20050191009Abstract: A hookup connection between a fiber optics hookup cable (7) and an endoscope optics (1). A connector (6) of the hookup cable (7) including a snap-in device (16) for snap-in engagement into at least one recess (17) running on the circumference of a hookup terminal (5) of the endoscope optics (1). The connector (6) includes a guide sleeve (13) and a locking element (16). The guide sleeve (13) receives and guides the hookup terminal (5) and constitutes, at an end near the cable, a cable socket (12). The locking element (16), which engages the recess, is radially displaceable in a supported manner and is configured in the region of the recess. A handling bush (18) is supported in a longitudinally displaceable manner on the guide sleeve (13) and is axially braced in both directions against the guide sleeve (13) by springs (20, 21).Type: ApplicationFiled: February 11, 2005Publication date: September 1, 2005Applicant: Olympus WINTER & IBE GMBHInventors: Mathias Kraas, Uwe Schrader, Frank-Michael Smid

Patent number: 6246823Abstract: An endoscopic optical system includes an elongate metal housing with a circular opening in its end in which a transparent window is received. The window has a cylindrical outer edge surface which is metallized over at least part of its area and is opposed to the cylindrical internal surface of the opening. An annular solder joint is provided in the gap between the opposed cylindrical surfaces. The solder joint has a thickness in the direction perpendicular to the window which is only a proportion of the thickness of the window.Type: GrantFiled: August 10, 1999Date of Patent: June 12, 2001Assignee: Olympus Winter & Ibe GmbHInventors: Mathias Kraas, Helmut Hirsemann
