Abstract
Abstract A suppressor device for the supply conductors of electrical and electronic equipment of the type generating high frequencies, as well as being utilizable as a line suppressor for shielded spaces, in which a metal housing is divided by two partition walls into three successive high frequency shielded chambers with multiple leadthrough capacitors being provided in the respective partition walls, and a current-compensated ring-core choke and a rod-core being disposed in the central chamber, one of the leadthrough capacitors, the ring-core choke, the rod-core choke and the other of the leadthrough capacitors being connected in series.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A suppressor device for at least a pair of supply conductors of a power supply line for supplying electrical power to electrical and electronic equipment of the type generating high frequencies, as well as being utilizable as a line suppressor for shielded spaces, employing a metal housing which is divided by two partition walls into three successive high frequency shielded chambers containing choke coiLs, capacitors and connecting terminals, characterized in that one multiple lead through capacitor is provided in each partition wall, with a currentcompensated ring-core choke and a second rod-core choke being disposed in the central chamber, each choke being operatively connected to both of such conductors, one of said lead through capacitors, the ring-core choke, the second rod-core choke and the other of the lead through capacitors being connected in series.
Claim 2
Dependent Claim
133 words
A suppressor device for at least a pair of supply conductors of a power supply line for supplying electrical power to electrical and electronic equipment of the type generating high frequencies, as well as being utilizable as a line suppressor for shielded spaces, employing a metal housing which is divided by two partition walls into three successive high frequency shielded chambers containing choke coiLs, capacitors and connecting terminals, characterized in that one multiple lead through capacitor is provided in each partition wall, with a currentcompensated ring-core choke and a second rod-core choke being disposed in the central chamber, each choke being operatively connected to both of such conductors, one of said lead through capacitors, the ring-core choke, the second rod-core choke and the other of the lead through capacitors being connected in series.
Claim 3
Dependent Claim
81 words
A device according to claim 1, wherein each of said multiple lead through capacitors comprises a pair of capacitor sections, said chokes each having a winding for each conductor, each of the latter being connected in series with a respective winding on each of said chokes, one of said conductors having a capacitor section of each pair disposed between it and the housing, and having the other capacitor section of each pair disposed between it and the other of said conductors.
Claim 4
Dependent Claim
23 words
A device according to claim 2, wherein first-mentioned conductor comprises a neutral conductor, and said other of said conductors comprises a phase conductor.
