- the laterally outer module contact sections 108 are located on axially opposite sides of the lens module housing part 22 with respect to the axis 54.
- the laterally Inner module contact sections 90 are each located between the laterally outer module contact sections 108. When the housing 16 is mounted, each laterally outer module contact section 108 is further away from the receiving opening 28 than the laterally inner module contact section 90 on the same side of the receiving opening 28.
- the front outer module contact section 110 extends between the two laterally outer module contact sections 108.
- the front side of the lens module housing part 22 is the side in which the lens holder 24 is arranged.
- the front outer module abutment section 110 extends on the side of the front inner module abutment section 92 facing the front of the lens module housing part 22.
- the front outer module abutment section 110 runs parallel to the front inner module abutment section 92 and parallel to the Axis 54.
- FIG. 12 shows a section perpendicular to the axis 54 through one of the laterally inner module contact sections 90.
- the section also shows the laterally outer module contact section 108 in front of it.
- the laterally outer module contact sections 108 each have a laterally outer module contact surface 112.
- the laterally outer module contact surfaces 1 12 run parallel to the laterally inner module contact surfaces 96 when viewed in the direction of the axis 54.
- the course of the two laterally outer module contact surfaces 1 12 when viewed in the direction of the axis 54 is the same.
- the laterally outer module contact surfaces 1 12 each have a curved section 116, an upper straight section 1 18 and a lower straight section 120.
- the curved sections 1 16 each merge into the upper straight sections 1 18.
- the upper straight sections 1 18 run tangentially to the respective curved sections 1 16.
- the upper straight sections 1 18 are flat surfaces.
- the upper straight sections 1 18 each merge into the lower straight sections 120 after a bend of slightly more than 90°.
- the lower straight sections 120 are flat surfaces.
- the lower straight sections 120 run approximately parallel to a respective imaginary tangent to the curved sections 116 at the rear end of the laterally outer module contact sections 108.
- the curved sections 62 of the laterally inner main contact surfaces 60, the curved sections 78 of the laterally outer main contact surfaces 76, the curved sections 102 of the laterally inner module contact surfaces 96 and the curved sections 116 of the laterally outer ones extend Module contact surfaces 1 12 viewed in the projection in the direction of axis 54 in sector 64.
- the lens module housing part 22 When assembling the housing 16, the lens module housing part 22 is placed with its inside first from the top 52 over the receiving opening 28 of the main housing part 18.
- the laterally inner module contact surfaces 96 slide along the corresponding temporal inner main contact surfaces 60 and the laterally outer module contact surfaces 1 12 slide along the laterally outer main contact surfaces 76.
- the lens module housing part 22 is screwed, for example, by means of screws which lead through corresponding screw openings 122 in the top of the main housing part 18, designated in Figure 5.
- the outer main contact surfaces 76 and 84 of the outer main contact frame 46 are pressed tightly against the corresponding outer module contact surfaces 1 12 and 1 14 of the outer module contact frame 88.
- the inner main abutment surfaces 56, 58 and 60 of the inner main abutment frame 44 are pressed tightly against the corresponding inner module abutment surfaces 96, 98 and 100 of the inner module abutment frame 86.
- the contact surfaces 56, 58, 60, 96, 98 and 100 of the inner contact frames 44 and 86 each run at a greater distance from the axis 54 than the contact surfaces 76, 84, 1 12 and 1 14 of the respective outer contact frames 46 and 88 , a labyrinth-like sealing area is created between the inner contact frames 44 and 86 and the outer contact frames 46 and 88.
- the outer contact frames 46 and 88 protect the sealing areas between the inner contact frames 44 and 86 from the environment.
