Description

Capacitor for the derivation of high frequency vibrations from an electrical one Lead The invention relates to a capacitor for dissipating high frequency vibrations from an electrical line with one passed through the capacitor housing itself and here on one end of the Kon.densatorwickels with one of the in itself short-circuited capacitor connections connected conductors, while the other assignment connected to the capacitor housing on the other end face of the capacitor winding is. Since it is very important with such capacitors that the whole effective The surface of the conductor is in contact with the non-earthed capacitor assignment comes and that @ electrically good conductive connections between the line and the one capacitor assignment and between the other capacitor assignment and the capacitor housing exist, it is proposed according to the invention, these connections by resilient Contact plates each with a hole provided in their center for the passage of the conductor, with the contact plates only under the crimping pressure of the capacitor housing and after closing the capacitor housing completely cover both ends of the condenser coil.

In the figure, in which a capacitor is shown in section as an exemplary embodiment of the subject matter of the invention, a is a capacitor housing through which a conductor b is passed centrally. The lead-through of the conductor b is accomplished on one end face by a hollow rivet c soldered to the conductor b, by means of which the conductor b is attached to the bottom ä of the capacitor housing a. To isolate the hollow rivet c and thus the conductor. b against the capacitor housing a are used two insulating disks d, which are inserted between the bands c 'of the hollow rivets c and the bottom ä of the capacitor housing a.

To carry out .des conductor b through: the capacitor housing a on the other end face of the capacitor winding: a package of a sealing compound c between insulating disks f, which are crimped into a pot-like structure g and serves. be held together by it. The metal-made pot g on a serving as a support for the capacitor winding insulation h inside the capacitor case a centered and sits with its bottom g 'directly on the edges of a projecting side of the capacitor winding and briefly closed in itself capacitor occupancy i on . Since the outer surface of the pot g rests snugly against the inner edge of the housing a and the pot g itself is firmly pressed against one end face of the capacitor coil by the flanged edge d 'of the capacitor housing a with its bottom g' serving as a contact plate, the capacitor is occupied i connected to: the capacitor housing a with good electrical conductivity.

The connection of the other capacitor occupancy marked with k with the conductor b is formed in a similar manner by a spring washer Contact plate l made, which with the conductor b at its passage point is firmly connected by the disk L. Likewise again the bottom g 'of the pot g to the an end face is also the one resting against one of the edges c 'of the hollow rivet c Spring washer l exerted by the flanging of the condenser housing edge d ' Pressure firmly on the: the other end face of the capacitor winding which is short-circuited in itself Capacitor assignment k pressed on.

The occupancy k is thus connected by the contact plate l to the conductor b passed through the capacitor housing and the occupancy i by the pot g to the capacitor housing a itself with good electrical conductivity.
