Abstract
A tip assembly for a bar code scanner having a concentric design which prevents rotational, axial and tilting movement among the components of the tip assembly. A tip housing with an internal detent is snap fitted over a scanner housing having multiple cantilevered, flexible beams, each with a circumferential groove adapted to receive the detent therein. An optical assembly housing containing optics is received within the scanner housing, between the flexible beams thereof. The optical assembly housing has tabs extending outwardly to mate with corresponding recesses in the beams to prevent rotation of the optical assembly relative to the scanner housing. The tip housing is sized to frictionally engage and press the beams inward so they frictionally engage the optical assembly housing. A scanner barrel is positioned about the scanner housing and extends to a position outward of the lip portion of the tip housing to prevent outward travel of the beams, thus locking the tip assembly components securely together.
