摘要： A shield assembly for a built-in lens set is introduced to a lens set built in a housing, in which the lens set has an optical head and the housing provides an aperture with respective to the optical head. A protrusive enclosure surrounding the aperture protrudes toward the optical head and is spaced from the optical head by a variable slim spacing. The shield assembly includes a shield ring for sleeving both the optical head and the protrusive enclosure and an elastic connecting unit for bridging the shield ring and the housing. By providing the shield ring to enclose always the spacing and the elastic connecting unit to engage elastically the lens set with the housing, the lens set can be prevented from dust-contaminating through the aperture, aged axial offsetting problem, and poor focus-adjusting performance caused by backlash existing in a driving mechanism.
