Damper with printed circuit board carrier

An electrically adjustable hydraulic shock absorber, comprising:

• a tube defining a fluid chamber;
• a piston assembly positioned within the tube and dividing the fluid chamber into a first working chamber and a second working chamber;
• a piston rod attached to the piston assembly and projecting out of the tube;
• a rod guide for guiding the piston rod;
• an electronically-controlled valve positioned within the rod guide for controlling a damping state of the shock absorber;
• a circuit board positioned around the piston rod, the circuit board adapted to actuate the electronically-controlled valve;
• a carrier housing receiving the circuit board and engaged with the rod guide, the carrier housing including at least one column;
• and
• a bumper cap mounted on the carrier housing and engaged with the at least one column;
• wherein the at least one column is adapted to transfer compressive axial loads from the bumper cap to the rod guide during an operation of the shock absorber.

• at least one terminal pin connecting the circuit board with the electronically-controlled valve, the at least one terminal pin being directly connected with the circuit board;
• a carrier housing receiving the circuit board and engaged with the rod guide, the carrier housing including at least one column, and a receiving portion for receiving the at least one terminal pin therethrough;
• and
• a bumper cap mounted on the carrier housing and engaged with the at least one column;
• wherein the at least one column is adapted to transfer compressive axial loads from the bumper cap to the rod guide during an operation of the shock absorber.
