Patent ID: 7504666

Claim:
An optical semiconductor package comprising: an annular support with a central passage to receive a cylindrical ring having a central opening holding an edge of a lens situated facing an optical sensor, wherein said annular support has, in said central passage, at least one axially extending local release recess in an inside wall of the central passage and wherein the cylindrical ring is equipped peripherally with a locally projecting, elastically deformable means, said axially extending local release recess receiving said locally projecting, elastically deformable means when the cylindrical ring is oriented at a first angular mounting position to allow axial movement of the cylindrical ring inside the central passage and, when the cylindrical ring is pivoted inside the central passage of the annular support away from the first angular mounting position, the locally projecting, elastically deformable means is moved out of said axially extending local recess of the annular support and is compressed against the inside wall of said central passage in order to secure an axial position of the cylindrical ring and lens inside the central passage relative to the annular support.
