Imager module for a camera or a sensor
An imager module for a camera or a sensor. The imager module includes a housing, a sensor carrier which is fixedly connected to the housing and on which an image sensor is arranged, an objective, and a holding element via which the objective is held and is aligned with respect to the image sensor. The holding element is arranged outside the housing and bridges a radial gap between the objective and the housing. The holding element is welded to the objective and/or to the housing.
1 . An imager module for a camera or a sensor, comprising:
a housing;
a sensor carrier which is fixedly connected to the housing and on which an image sensor is arranged;
an objective lens; and
a holding element via which the objective lens is held and is aligned with respect to the image sensor, wherein the holding element is arranged outside the housing and bridges a radial gap between the objective lens and the housing, and wherein the holding element is welded to the objective lens and/or to the housing.
2 . The imager module according to claim 1 , wherein the housing is a multipart housing.
3 . The imager module according to claim 1 , wherein the holding element is spot-welded to the objective lens and/or to the housing.
4 . The imager module according to claim 1 , wherein the holding element is manufactured from metal.
5 . The imager module according to claim 1 , wherein the holding element is manufactured from sheet metal.
6 . The imager module according to claim 1 , wherein the objective lens has, at least in a portion surrounded by the holding element, a metal outer contour for welding to the holding element, wherein the metal outer contour has at least one flattened portion.
7 . The imager module according to claim 1 , wherein the holding element is configured as a ring or disk with a central hole for accommodating the objective lens, wherein the hole has an inner contour adapted to a outer contour of the objective lens.
8 . The imager module according to claim 1 , wherein the housing is at least partially manufactured from metal.
9 . The imager module according to claim 1 , wherein the housing includes at least a first housing part configured to accommodate the sensor carrier and the image sensor, and a second housing part configured as a cover, wherein the first housing part and the second housing part are connected in a firmly-bonded and/or positive manner.
10 . The imager module according to claim 9 , wherein the second housing part configured as a cover has a collar which delimits the radial gap and extends into the housing.
11 . The imager module according to claim 9 , further comprising a seal accommodated in the radial gap.
12 . The imager module according to claim 1 , wherein the objective lens has at least one optical lens.
13 . The imager module according to claim 12 , wherein the at least one lens is in the form of a lens package.
