Imaging unit of a camera for recording the surroundings with optics uncoupled from a circuit board

1. An imaging unit of a camera for recording of surroundings, comprising: an image sensor, a lens to display the surroundings on the image sensor, a carrier, a separate carrier substrate for mounting the image sensor upon a first exterior surface of the carrier, and a circuit board arranged on the first exterior surface of the carrier laterally spaced apart from the separate carrier substrate, the circuit board having at least signaling and supply lines for the image sensor, wherein the image sensor is electrically contacted by the separate carrier substrate, and the separate carrier substrate is electrically connected to the signaling and supply lines using flexible electrical connections, resulting in flexible contacting between the circuit board and the separate carrier substrate, and further comprising a lens fastener of optically dense material forming a hollow space around the image sensor together with the carrier, the lens fastener being mounted on the carrier in an optically sealed manner, and 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 with a flexible and optically dense joint material.

2. The imaging unit of a camera according to claim 1 , wherein the lens fastener is arranged above the first exterior surface of the carrier circumferentially with a joint, and the joint is closed with a flexible and optically dense joint material.

3. The imaging unit of a camera according to claim 2 , wherein the lens fastener is fixated on the carrier through adhesion using the joint material.

4. The imaging unit of a camera according to claim 2 , wherein the joint material comprises silicone.

5. The imaging unit of a camera according to claim 1 , wherein the lens fastener is fixated on the carrier through adhesion using the joint material.

6. The imaging unit of a camera according to claim 1 , wherein the joint material comprises silicone.

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

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

9. The imaging unit of a camera according to claim 1 wherein the carrier comprises metal.

10. An imaging unit of a camera for recording of surroundings, comprising: an image sensor, a lens to display the surroundings on the image sensor, a carrier, a separate carrier substrate for mounting the image sensor upon a first exterior surface of the carrier, and a circuit board arranged on the first exterior surface of the carrier laterally spaced apart from the separate carrier substrate, the circuit board having at least signaling and supply lines for the image sensor, wherein the image sensor is electrically contacted by the separate carrier substrate, and the separate carrier substrate is electrically connected to the signaling and supply lines using flexible electrical connections, resulting in flexible contacting between the circuit board and the separate carrier substrate, and further comprising a lens fastener of optically dense material forming a hollow space around the image sensor together with the carrier, the lens fastener being mounted on the carrier in an optically sealed manner, wherein the lens fastener has a fastening means extending into a recess in the first exterior surface of the carrier, and a cross sectional area of the fastening means positioned parallel to a base of the recess increases towards the base, the fastening means extends into the recess to an extent that there is an intermediate space between a base of the fastening means and the base of the recess, and a space of the recess surrounding the fastening means including said intermediate space is filled with a curable material.
