The invention relates to a monolithically designed ceramic capacitor body for multiple capacitors. The capacitor body includes: a base plate provided with a metal coating, the base plate formed with a plurality of through-channels, the base plate having a first side and a second side; and a plurality of individual column-shaped capacitors each including at least a first column element extending outward from the first side of the base plate and a second column element aligned with the first column element and extending outward from the second side of the base plate. The invention also relates to a capacitor provided with the capacitor body and to filter plug provided with the capacitor.

Capacitor body and a filter plug including a capacitor formed with the capacitor body

A multi-pole angle-connecting device to be soldered onto a printed circuit board includes a planar filter, a continuous signal conductor assigned to each pole and having soldering ends on one side to be soldered to soldering points of the printed circuit board and ends on another side constructed as connector pins or plug-in sockets. In order to ensure that the angle-connecting device can be produced cost-effectively and can be soldered easily onto printed circuit boards, the filter is constructed as a filter plate which has openings through which the angular conductors are led and which rests on a metallic filter holder that is connected to ground and to a collar of the angle-connecting device. The filter holder has corresponding openings for leading through the soldering ends of the angular conductors, but with larger diameters. The planar filter is advantageously supported by a supporting carrier.

Multi-pole angle-connecting device

A plug connector having a housing and an insulating body in the housing is described. Contact inserts are provided and correspond to the total number of lines passing through, each with a connecting sleeve, insert foot, insert body and with sockets/pins, and at least one line is electrically connected via a matching circuit to the housing. The matching circuit is accommodated by the plug connector housing and is connected to the signal conductors and the housing ground. For this purpose, the connector receptacles are in the form of roughly cylindrical apertures with circumferential inner rings which, facing the filter chamber, have an axial groove, with a window toward the filter chamber. Each of the inserted contact inserts has a matching ring interacting with the inner ring and has a device to ensure that the contact insert is seated without any play, and that contact is made with the matching circuit.

Multipole plug connector for electronic signal lines

A multiple filter for a plug connector has at least one capacitor with a signal electrode and a ground electrode connected to the associated signal and ground line, respectively, such that it can be produced using not only discrete components but also using thick-film or thin-film technology, and such that it can also be used in the frequency range above 10 GHz. A block of capacitor columns is provided, which are combined in the block or are provided free-standing on a block base. The block insulating material is formed by the capacitor dielectric with a dielectric constant of 10 to 10 . Each capacitor column contains a capacitor which is formed by a signal conductor and a ground conductor. The signal electrode is formed either by the signal conductor itself or by layers connected thereto. The ground electrode is formed on the outer wall of the capacitor column and at least partially covers it.

Multiple filter

A capacitor having a signal electrode connected to a signal conductor, a ground electrode connected to a ground conductor and a dielectric disposed between the two. In the capacitor, delay-time-dependent limits are moved to higher frequency ranges in order to extend the applicability in the frequency range. This is accomplished by the signal conductor or the ground conductor being spaced apart from the signal electrode or the ground electrode and thus from the dielectric having a high dielectric constant. The signal conductor or the ground conduct is subdivided into at least two conductor regions that are separated in the direction of signal propagation. Each of the conductor regions is electrically connected via at least one conductor connector to the signal conductor or to the ground conductor, respectively.
