Definitions

  • Patent Document 1 discloses an example of an optical connector having a plug receptacle structure (also referred to as a "plug receptacle connector").
  • a ferrule holding a built-in optical fiber is attached to a housing member of the optical connector via a flange arranged on the outer periphery thereof (for example, patent See FIGS. 5 and 8 of Document 1).
  • Patent Documents 2 and 3 also disclose optical connectors having similar configurations.
  • the force from the housing is less likely to be applied to the ferrule, the ferrule is less likely to bend due to deformation of the housing, and the optical connection loss due to bending can be reduced.
  • the pair of claws and the pair of recesses may be provided along the left-right direction of the optical connector. In this case, the gap between the claw portion and the recess tends to be small, and the ferrule is difficult to move laterally with respect to the housing.
  • the housing has high rigidity in the left-right direction and is difficult to deform.
  • the ferrule holder 20 includes a tubular holder body 21 that houses the ferrule 10 therein, a collar portion 22 that protrudes outward along the radial direction (second direction) orthogonal to the longitudinal direction from the outer periphery of the holder body 21, have The collar portion 22 is provided at one end (plug side) of the holder main body 21 .
  • the ferrule holder 20 is arranged so that the collar portion 22 is positioned at the center of the ferrule 10 in the longitudinal direction. In FIG. 4, in order to make the arrangement shape of the ferrule holder 20 easier to understand, the ferrule holder 20 is shown as it is without having a cross-sectional shape.
