A delatch actuator with a delatch arm is disposed on the connector housing for movement from a locking position to an unlocking position. One of the adapter latch element and connector latch element is a bendable latch hook and the other is a locking channel. When the connector housing is mated with the adapter, the delatch arm allows the bendable latch hook to latch with the locking channel in the locking position and unlatches the bendable latch hook from the locking channel as it moves to the unlocking position. An actuator lock movably supports a blocking member on the connector for selectively blocking the delatch actuator from moving to the unlocking position.

  • Patent number: 11520110
    Abstract: A first optical device is adapted to couple to a second optical device along a coupling direction and includes two spaced apart pairs of leading and trailing pads, such that when the first optical device lands and slides on a landing surface of the second optical device to optically couple to the second optical device, and for each pair of leading and trailing pads, the leading pad prevents any debris on the landing surface from collecting on the trailing pad. Upon full coupling of the first optical device with the second optical device, the leading pads do not make contact with the landing surface. The first optical device may be, for example, an optical ferrule or a cradle having a recess adapted to receive an optical ferrule.
