  • the wearer of the optical device “at least surrounds part of its circumference, “says that the equipment carrier is not must be closed on its circumference. He has to only surround optical device to the extent that a non-positive Definition, e.g. by clamping in the protective housing. With in other words, the equipment carrier must be in several axial directions or support directional components on the protective housing. With a hollow cylindrical protective housing, it is sufficient, for example, if the Device carrier surrounds the optical device to more than 180 degrees. There are but there are other possible variations:
  • the device carrier at least in is essentially designed as a hollow cylinder. It is only essential that that optical device can be attached to it.
  • the outer circumference can also be interrupted, e.g. star-shaped and / or in the form of radial Support or struts.
  • the invention provides a protective housing as described at the beginning Genus created that can be manufactured and produced particularly cost-effectively especially (but not exclusively) has small dimensions and is universally applicable, especially for small cameras or others small optical devices such as headlights, motion detectors and the like.
  • the optical devices are very simple reliable, vibration-free or low-vibration and slidable confined space within a very low in the application segment small protective housing.

He is compared to the housing jacket 4 by an expandable clamping body 9 held firmly (by friction) and also with the optical Device 2, which is held by the screws 10, around the housing axis A-A rotatable.
  • the expandable clamp body 9 is a round cord ring educated. Supported by the structural length of the housing support through the collar 8b, the arrangement is guided like a piston and against Tilting and independent moving secured.
  • the equipment carrier 8 In the equipment carrier 8 are two spacers - distributed over the circumference 11 screwed in, which after inserting the module on the Support window wall 5 and thereby stops for an accurate Distance of the lens 3 from the window wall 5 form what the Exploitation of the maximum angle of view of the lens is important. It can also use spacers 11 of different lengths or adjustable Spacers are used.
  • the housing jacket 4 For inserting the window wall 5, the housing jacket 4 has the inside diameter enlarged to form a step 4a and above by a Canopy 4b extended.
  • the fixed wall is also through one spreadable ring 12 held. Instead of an extension, you can appropriately shaped ring can be placed, as shown in the figures 4 and 5 is shown.
  • the rear wall 6, in which a cable duct 13 is arranged, is held non-positively by a clamping device 14 as follows:
  • the Rear wall 6 has a collar 6a, forming an outer step, which carries an expandable clamp body 15. Through a perforated disc 16 (to carry out the lines) and a clamping screw 17 is the Clamping body 15 axially compressed, wherein it extends radially and brings about a positive connection to the housing shell 4.
  • the housing shell 4 also has a threaded connector 18 for the Engagement of a tripod screw 19 with a ball head 19a, through a Knurled nut 20 can be determined.
