  • Patent number: 10627580
    Abstract: A multi-fiber, fiber optic connector has a housing having a first end for receiving a multi-fiber fiber optic cable and a second end having openings for said fibers from said cable. First and second key slots are provided for accepting a removable key for setting the polarity of the fibers within the connector, with the first and second key slots located on opposing sides of the connector. The connector has guide pins or guide pin receiving holes for guiding the connection with a second connector. The removable key is movable between the first and second key slots, the key slot with the removable key corresponding to a first active slot and the key slot without the removable key corresponding to a non-active slot. When the removable key is in the first key slot, it results in the first key slot being active with the fibers being presented within the connector in a first polarity.

  • Patent number: 10488601
    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.
