Printed circuit board
A printed circuit board includes at least two rigid printed circuit board parts which are connected to one another by at least one flexible connecting part which is thinner than the rigid printed circuit board parts. The at least two rigid printed circuit board parts can be moved toward one another by bending the flexible connecting part. A groove, which is produced by the different thickness of the rigid printed circuit board parts relative to the flexible connecting part, is filled with an elastic material.
1. A printed circuit board, comprising:
at least two rigid printed circuit board parts;
at least one flexible connecting part interconnecting said at least two rigid printed circuit board parts;
said at least one flexible connecting part being thinner than said at least two rigid printed circuit board parts defining a groove produced by said different thicknesses of said at least two rigid printed circuit board parts and said at least one flexible connecting part;
said at least one flexible connecting part being configured to bend to allow said at least two rigid printed circuit board parts to be moved toward one another;
an elastic material filling said groove; and
said at least one flexible connecting part having a bottom surface extending between said at least two rigid printed circuit board parts and contacting said elastic material, said bottom surface configured to form a concave shape as said at least two rigid printed circuit board parts are moved toward one another.
2. The printed circuit board according to claim 1 , wherein said at least two rigid printed circuit board parts and said at least one flexible connecting part are integrally formed.
3. The printed circuit board according to claim 1 , wherein said at least two rigid printed circuit board parts and said at least one flexible connecting part are formed in one piece.
4. The printed circuit board according to claim 2 , wherein said groove is a deep-milled groove formed in an integral printed circuit board.
5. The printed circuit board according to claim 2 , wherein said groove is a deep-milled groove formed in a one-piece printed circuit board.
6. The printed circuit board according to claim 1 , wherein said elastic material is a silicone.
7. The printed circuit board according to claim 1 , wherein said elastic material is an insulator.
