  • Patent number: 10386583
    Abstract: When a second housing 80 and a first housing 30 are approached to each other along an axial direction, a body portion 62 of a second fixing member 60 begins to enter in an opening 81 of the second housing 80. Since a vertical wall surface 81a and a cylindrical surface 81b are formed on the opening 81 to substantially match the outer shape of the rear end of the body portion 62, when the second housing 80 is inserted to the first housing 30 while keeping the relative angle until the second housing 80 abuts on a first fixing member 40 which closes the opening and rotating the second housing 80 with respect to the first housing 30 by 90°, a protrusion 64 faces and enters a recessed engagement portion 83 formed on the vertical wall surface 81a. Thus, the protrusion 64 and the recessed engagement portion 83 are fitted and fixed.

  • Patent number: 10386585
    Abstract: A fitting for signal connector coupling has a bayonet attachment mechanism including a groove in a fitting wall including guiding groove and retaining groove portions, the retaining groove portion having a recess forming a positive lock to interact with a protruding member of a locking cap or collar, which may be turned onto the fitting until the protruding member resiliently snaps or springs into the recessed portion resisting loosening and providing haptic feedback indicating accomplishing secure attaching. A method of attaching a fitting to another device, includes placing and turning the another device on a cylindrical wall of the fitting while interaction between a groove in the fitting wall and a protuberance on the another device guides the another device rotationally about the fitting wall, and continuing turning moves the protuberance into a positive lock location in a retaining portion of the groove and also provides haptic feedback indicating attachment.
