Definitions
- the present invention is in the field of manufacturing high voltage electrode assemblies, which as discharge or charging electrodes in various Applications.
- Such high-voltage electrodes come in a variety of different designs and arrangements known. All versions include the installation of various electrically conductively connected, preferably soldered, in one Components introduced into the insulating material, together.
- the production of the high-voltage electrode arrangements known from the prior art is comparatively complex because the individual components like High voltage resistors, emission peaks, printed circuits and connectors by hand either built directly into an insulating body or be assembled into a semifinished product outside, and then in the insulating body to be installed.
- the connection between the individual Components, an electrode assembly built according to the prior art takes place in crimp screw or preferably in soldering technology.
- the so created by hand Connections of the individual components to each other, or the manufacture the semi-finished products and their installation in an insulating body represent the most expensive Share in the high-voltage electrode arrangements known from the prior art represents.
- the invention has for its object to make a generic high-voltage electrode arrangement less expensive. This object is achieved in the generic high-voltage electrode arrangement according to the preamble of the main claim according to the invention by its characterizing features.
- a contact spring made of electrically conductive material is introduced so that a large number of individual or groups of preferably rectangular Ceramic substrate resistances, perpendicular to the longitudinal extension of the insulating body can be inserted.
- the encapsulation holds the one produced according to the invention High-voltage electrode arrangement permanently in form and contact closure.
- such a Potting e.g.
- a high-voltage electrode arrangement according to the invention is thus in the range of Contact spring and contact surface of the resistor capable of bending and / or Pressure loads on the insulating body without changing the contact quality maintain evenly.
- Individuals or groups of preferably serve as high-voltage resistance predominantly rectangular ceramic substrate resistors based on at least one Side of the ceramic substrate one or more surface-mountable emission peaks, connected to a thick-film resistance meander, connected to a contact area exhibit.
- the ceramic substrates are on both sides assembled and through a through hole in the area of the contact surface Front and back electrically connected. Instead of the ceramic substrate.
- a correspondingly high-voltage-resistant ceramic chip capacitor can also provide resistance used for pure AC operation of the high voltage electrode assembly become.
- the ceramic substrate points in the area between resistance meanders and surface-mountable emission tip a predetermined breaking point in the ceramic substrate which is broken off after the fixation in the insulating body and the Emission tip protrudes as a free tip over the surface of the potting compound.
- a major advantage of the high-voltage electrode arrangement according to the invention consists in the fact that all connection techniques, or the elaborate manufacture of semi-finished products can be eliminated.
- FIGS. 1 to 3 an embodiment of the high-voltage electrode arrangement according to the invention in its various stages of manufacture is shown in FIGS. 1 to 3.
- Fig. 1 shows the high-voltage electrode arrangement (1) according to the invention in section.
- Fig. 2 shows a ceramic substrate resistor (20) according to the invention in plan view and section, with one-sided and two-sided assembly.
- the invention relates to a high-voltage electrode arrangement with a plurality of ceramic substrate resistors arranged in parallel to one another in a groove of an insulating body are introduced, and with each other by an electrically conductive Contact spring mechanically fixed and electrically connected.
- the insulating material body (2) has a groove (3) in which the ceramic substrate resistors (20, 25) are introduced and mechanically fixed and electrically contacted by a contact spring (4) so that such a high-voltage electrode arrangement (1) can be produced as inexpensively as possible .
- the ceramic substrate resistors (20, 25) have a printed thick-film resistance meander (22) on at least one side, which is electrically connected, preferably soldered, to the surface-mountable emission tip (21) on the one hand and to the contact surface (23) on the other hand.
- the ceramic substrate resistor (20, 25) has a predetermined breaking point (24) in the area behind the emission tip (21) , which can break off after fixing the emission tip as a free tip protruding over the upper edge of the ceramic substrate resistor and the potting.
- the ceramic substrate resistors (20, 25) and the contact spring (4) are held in the insulating body (2) by the potting compound (5) permanently in positive and contact.
