Connection structure for a vibration absorber has a printed circuit board with an electronic component all cast in a casing with a plastic jacket to protect against dirt

A vibration absorber has a cylinder (1) with a piston rod (PR) (3) moving on-axis. A guiding/sealing unit (7) guides the PR out of the top end of the cylinder. A piston unit (9) with a piston valve structure (11) fastens inside the cylinder on the PR. Electronic components on a printed circuit board...

Beschreibung
Zusammenfassung:A vibration absorber has a cylinder (1) with a piston rod (PR) (3) moving on-axis. A guiding/sealing unit (7) guides the PR out of the top end of the cylinder. A piston unit (9) with a piston valve structure (11) fastens inside the cylinder on the PR. Electronic components on a printed circuit board (PCB) are protected against dirt and moisture. A polyurethane foam coating is applied to the PCB. Schaltungsanordnung, umfassend eine Leiterplatte mit mindestens einem elektronischen Bauteil, wobei diese Leiterplatte von einem Gehäuse eingeschlossen ist, das wiederum eine äußere Kunststoffummantelung als Schutz gegen Schmutz aufweist, wobei das Gehäuse von einer Beschichtung gebildet wird.
