Abstract

A camera module that includes an objective lens with an electrical interface and a device for electrically contacting the objective lens in the area of the electrical interface. The device for electrically contacting are also connected to an electronics system, in particular to a circuit board, of the camera module. The electrical interface is formed at the objective lens on the outer circumferential side, and the device for electrical contacting includes an annular body situated on the objective lens on the outer circumferential side, with contacts formed on the inner circumferential side. A method for manufacturing a camera module is also provided.

First claim

1 - 12 . (canceled)

13 . A camera module, comprising:
an objective lens with an electrical interface; a device configured to electrically contact the objective lens in an area of the electrical interface, the device configured to electrically contact also being connected to an electronics system of the camera module; wherein the electrical interface is formed at the objective lens on an outer circumferential side of the objective lens, and the device configured to electrically contact includes an annular body situated on the objective lens on the outer circumferential side of the objective lens, with contacts formed on an inner circumferential side of the annular body.

14 . The camera module as recited in claim 13 , wherein the electronics system includes a circuit board.

15 . The camera module as recited in claim 13 , wherein the annular body is connected to the objective lens in a force-fit and/or firmly bonded manner.

16 . The camera module as recited in claim 13 , wherein the annular body is made of an elastically deformable material, at least in areas, and rests against the objective lens on the outer circumferential side, under radial pretensioning.

17 . The camera module as recited in claim 13 , wherein the annular body includes a slot and is configured as an open ring.

18 . The camera module as recited in claim 13 , wherein the annular body is connected to the electronics system of the camera module via at least one electrical conductor.

19 . The camera module as recited in claim 18 , wherein the at least one electrical conductor includes a cable.

20 . The camera module as recited in claim 13 , wherein the annular body is fastened to a housing part of the camera module via a flexible sheet material.

21 . The camera module as recited in claim 20 , wherein the housing part is an objective lens holder.

22 . The camera module as recited in claim 20 , wherein the flexible sheet material is a fabric or a mesh or a film or a diaphragm.

23 . The camera module as recited in claim 20 , wherein the sheet material is held in the housing part of the camera module via a mounting ring.

24 . The camera module as recited in claim 23 , wherein the sheet material includes or forms strip conductors that connect the contacts of the annular body to an electrical interface that is formed at the mounting ring.

25 . The camera module as recited in claim 13 , wherein the objective lens includes a cone and/or an annular collar, in an end section facing the electronics system.

26 . A method for manufacturing a camera module, the method comprising the following steps:
inserting an objective lens into a housing part and aligning the objective lens with respect to an image sensor of the camera module; wherein, for electrical contacting, the objective lens, upon insertion into the housing part, is introduced into an annular body, so that an electrical interface of the objective lens, formed on an outer circumferential side of the objective lens, comes into contact with contacts formed at the annular body on an inner circumferential side of the annular body.

27 . The method as recited in claim 26 , wherein the housing part is an objective lens holder.

28 . The method as recited in claim 26 , wherein a force-fit and/or firmly bonded connection between the objective lens and the annular body is established upon insertion of the objective lens into the annular body.

29 . The method as recited in claim 26 , wherein the annular body is directly or indirectly held at the housing part before the objective lens is inserted.
