DE1684740U - RESISTOR COMBINATION AS SWITCHING UNIT. - Google Patents

Description

Widely used in combination as a switching unit,

The innovation relates to a resistor _{combination P,} which can be used, for example, as a terminal resistor for current transformers for high frequencies, then in case of apparent resistance measurements or also as an attenuator, such as 2ichteiler _3. ,

The innovation according resistance is gekennscichnct characterized. Is arranged that in a tubular resistance another stäbchenfürmiger Y / esistance, and that on one end face of the internal resistance with the outer _s is concentrically connected thus the internal resistance provides a coaxial feedback for a terminal post of the 7 / resistance _? which, however, depending on the intended use _9, can also be contacted externally _c

As it arrives at the resistor combination in substantially eino concentric flow guide and gleichmässigo current density ρ I3T it important but at least the external resistance of a resistive layer on an insulating Sragrohr form The resistance layer may for example be a Hartkohle- or metal layer may be ₃ it can also be a Acting splint mixture that is dipped by spraying

The external resistance is expediently on the side on which it is concentrically connected to the internal resistance ₃ contacted by means of a metal cap known per se Power supply, passed through, a hole in the cap mold; is soldered to this «. The other side of resistor äusscren is contacted by means of a clamp ;, which has a collar _{flange-0 P} ^ designed to con- 'centric connection with a Gehäusev / and served dom or outer conductor of a coaxial cable connector

In the identified applications, the external resistance is designed as a particularly low-resistance V / resistance ρ, for example in the order of magnitude of 1 ohm? while the internal resistance as a wave resistance, for example the size of 60 ohms «

In the drawing, the innovation is shown in section _υ a is the tubular insulating support body on which 3ich _? denoted by b, the resistance layer indicated only by a strong line. On the one hand, in the illustration on the left-hand side, this resistance layer b is contacted by means of the contact cap Clamp d serves _? which has a flange-like approach e «, in the center of the contact cap c, denoted by f, the connecting pins for the internal resistor g are provided. The resistor g can be one of the usual, well-known rod-shaped resistors, for example with contact caps h ₀ .
