Abstract: A tool for a plug to which a cable having its basal end covered with a boot is attached is disclosed. The plug includes a plug body fitted to an adapter and a slider supported on the plug body. The tool includes an insertion portion that catches the slider, and a boot surrounding part that has a sleeve-like shape and accepts insertion of the cable and the boot, to accommodate the boot while the insertion portion is catching the slider. The boot surrounding part includes a slit extending along an entire length in an axial direction of the boot surrounding part and having a width greater than a diameter of the cable and smaller than a maximum diameter of the boot. While the insertion portion is catching the slider, the boot surrounding part is positioned inner than an outermost shape line of the plug as seen in the axial direction.

Abstract: Provided is an optical connector plug which, even when a predetermined load is applied to a plug frame and the plug frame is warped to a vertical upper side of a guide protrusion portion, prevents disengagement of an engagement head and an optical conductor adaptor. In an optical connector plug, an axial front end of an engagement head of an engagement latch is separated axially rearward from an axial rear end of a guide protrusion portion, and is close to the axial rear end of the guide protrusion portion. According to the optical connector plug, when a predetermined load is applied to a plug frame and the plug frame is warped to a vertical upper side of the guide protrusion portion, the axial front end of the engagement head is supported by the axial direction rear of the guide protrusion portion, so that the engagement head is prevented from moving vertically downward from the guide protrusion portion.

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.

Abstract: In a duplex optical connector plug 10A, when one of first and second optical connector assemblies 11a, 11b is rotated around its axis in a clockwise direction or a counterclockwise direction, a rotational force of one of first and second gears is transmitted to the other of the gears by an intermediate gear. Thereby, interlockingly with the one of the optical connector assemblies 11a, 11b, the other of the optical connector assemblies 11a, 11b is rotated around its axis in the clockwise direction or the counterclockwise direction which is the same direction as the optical connector assemblies 11a, 11b.

Abstract: A plug attached to a terminal part of a cable includes a plug main body engaged to an adaptor, a slider and a tool. The tool includes an insertion portion having a tapered part and an engaging projection and an operation part. When the operation part is pulled with a second surface of the insertion portion inserted in a slot being disposed in parallel with an extraction direction, the engaging projection is engaged with an engaging portion of the slider, the slider is moved integrally with the tool and the plug main body is pulled out from the adaptor. When the operation part is pulled with an inclined surface of the tapered part being disposed in parallel with the extraction direction, the engaging projection is released from an engaging state with the engaging portion and the tool is detached from the slider.

Abstract: A plug attached to a terminal part of a cable includes a plug main body to be connected to an adaptor, a latch, which is provided at the plug main body so as to be elastically displaceable from an outside of the plug main body toward an outer surface of the plug main body and which is engaged to the adaptor, and a slider including a cover part that is disposed at the outside of the latch. When the cover part is pushed down toward the outer surface or when the slider is moved in an extraction direction in which the plug main body is to be extracted from the adaptor, the latch is pushed down toward the outer surface and the engaging state of the latch is released.
