Embodiment Construction

[0028] figure 1 A detail of a piston-cylinder assembly 1 , for example an adjustable shock absorber, is shown. A piston rod 5 is guided axially movably in the cylinder 3 and serves in particular as a line receptacle 7 for a power supply line 9 of an electric coil 11 . The coil 11 comprises a coil base 13 and a winding 15 which is only schematically shown. In this exemplary embodiment, a cup-shaped housing 17 which accommodates the coil 11 is fastened to the hollow piston rod 5 . In principle, the coil 11 can also be arranged directly in the hollow piston rod 5 .

[0029] The coil base 13 is preferably produced from plastic by means of an injection molding method and comprises a tube section 19 for receiving the winding 15 and a cover 21 which is closed at the end. The winding ends, not shown, pass through the cover 21 as far as the cover surface 25 pointing in the direction of the housing bottom 23 . The individual litz wires 27 of the supply line 9 are on the cover surfa...

Abstract

Disclosed is a supply line that is connected to a main coil member, a pull resistance mechanism being provided between the supply line and the main coil member, the main coil member comprising a bushing for receiving one end of the supply line, the bushing being part of a retaining connection between the supply line and the main coil member.

Description

technical field [0001] The invention relates to a tension section for a power supply line in a tubular component according to the preamble of claim 1 . Background technique [0002] A piston-cylinder assembly is known from DE 10 2012 203 542 A1, which has a power supply line to an adjustable damping valve. In the prior art, a multi-core wire forms the supply line to the coil. [0003] During production or assembly of the piston-cylinder assembly, it cannot be ruled out that a loosening of the connection between the conductive strand and the coil is caused by incorrect manipulation of the piston-cylinder assembly, for example by loading the power supply line. In order to also be able to cope with load conditions, the coil has a coating which also surrounds the coil-side end of the supply line. The coating is relatively expensive to produce, since the injection mold must have sealed outlets for the power supply lines. During production, the coils must be inserted manually i...
