Rotor sliding contact spring far variable capacitors

The subject of the increase in price is a rator sliding contact spring for variable capacitors, especially small versions

for "OKI ·

Ea is known to have "pressed or soldered slip rings" pushed onto the Sotorach.se in connection with to use sliding contacts attached to the housing. It has also been suggested that a To attach a ring groove in which the contacts slide, or to design a motor end lamella itself as a slip ring or sliding contact.

These known arrangements have the fact that either a greater overall length is required or none Sufficiently soft springing of the sliding contacts in the case of single-element versions is to be achieved, or else, additionally, at Formation of a rotor end lamella as a sliding contact a « smaller effective covering area is available. The taxation avoids these disadvantages. This is done by that the sliding spring made of spring material, the outer shape of which can correspond to the rotor lamella, has in common, without an additional ring groove, with a rotor end lamella on the other Rotor axis is attached.

Since the grinding spring is independent of the rotor end lamella made of stronger material, everyone can use it If a soft suspension can be achieved. The sanding pen can be divided into several tongues, each one for itself Give contact so that, in addition to reducing the size of the transition resistance also means a reduction in the on VHF disruptive self-induction of the spring tongues occurs. The sliding contacts either slide on a housing wall or on a metal plate attached to it.
