Abstract

An imaging unit of a camera for recording the surroundings has an image sensor with a lens for the display of the surroundings on the image sensor. The image sensor and the lens are held by a carrier. The camera additionally has a circuit board and at least the signal and the supply lines of the image sensor arranged an the carrier. The image sensor is mounted an a carrier substrate, which similar to the lens, is arranged on the carrier at a distance from the circuit board, and has a flexible electrical connection to the circuit board.

Claims

1. An imaging unit of a camera for recording of surroundings with a lens on an image sensor, the image sensor being held by a carrier, and the carrier including a circuit board and at least signaling and supply lines for the image sensor, wherein the image sensor is mounted on a separate carrier substrate, the lens and the carrier substrate are arranged on the carrier at a distance from the circuit board, and the image sensor is connected to the signaling and supply lines using flexible connections.

2. An imaging unit of a camera according to claim 1, wherein a lens fastener of the lens is made from optically dense material and forms a hollow space around the image sensor together with the carrier, by having the lens fastener mounted on the carrier in an optically sealed manner.

3. An imaging unit of a camera according to claim 2, wherein the lens fastener is arranged above the carrier circumferentially with a joint, and the joint is closed using a flexible and, optically dense joint material.

4. An imaging unit of a camera according to claim 3, wherein the lens fastener is fixated on the carrier through adhesion using the joint material.

5. An imaging unit of a camera according to claim 3, wherein the joint material comprises silicon.

6. An imaging unit of a camera according to claim 2, wherein the lens fastener has a penetration, through which the circuit board extends into the hollow space, so that there is a joint, between the lens fastener and the circuit board, and the joint is closed using a flexible and optically dense joint material.

7. An imaging unit of a camera according to claim 6, wherein the lens fastener is fixated on the carrier through adhesion using the joint material.

8. An imaging unit of a camera according to claim 6, wherein the joint material comprises silicon.

9. An imaging unit of a camera according to claim 2, wherein the lens fastener has a fastening means extending into recesses in the carrier, and a cross sectional area positioned parallel to a base of the recesses in towards the base, each fastening means extends into a recess of the carrier as far, so that there is an intermediate space between a base of the fastening means and the base of the recess, and the space of the recess surrounding the fastening means including said intermediate space is filled with a curable material.

10. An imaging unit of a camera according to claim 1, wherein focus of the lens is adjustable.

11. An imaging unit of a camera according to claim 1, wherein the image sensor is encased.

12. An imaging unit of a camera according to claim 1, wherein the carrier comprises metal.
