Estimating the term…
The base plate module of an electromagnetic switching device, specifically a contactor, is mounted on a base plate (1). The base plate module contains the core (2) of the electromagnet, a magnet coil (5), a printed circuit board (10) with its connected ancillary devices, as well as the contact plugs (16, 17) and terminals (24, 25), both of which are accessible from the outside. Printed circuit board (10) is mounted on base plate (1) and is located between base plate (1) and core (2), which is mounted on the base plate. Strip conductors (12, 13, 14), on the side facing core (2), feature several spring-loaded stub contacts (19, 20) and/or contact plugs (21, 22), all of which are vertically mounted on circuit board (10). Flange (7) of coil module (6), which is oriented toward base plate (1), provided with terminals (23) of magnet coil (5). With magnet coil (5) in the mounted position, terminals (23) of magnet coil (5) are in contact with the spring-loaded stub contacts (19) of strip conductors (13). Contact plugs (21, 22) serve as receptacles for card (27) which contains electronic circuitry. All electrical connections in the base plate module are made by strip conductors (12, 13, 14) of printed circuit board (10).
The base-plate module of an electromagnetic switching device, specifically that of a contactor, consisting of a base plate, the core of an electromagnet which is installed in said base plate module, a magnet coil for activating the electromagnet, and a printed circuit board consisting mainly of electrically insulating material, where said printed circuit board provides electrical connections between the terminals in the base-plate module and the externally accessible terminals of the switching device, and where said base plate module contains, at least on one side, several strip conductors and is characterized in that strip conductors (12, 13, 14), at the side facing core (2) of circuit board (10), which is mounted on base plate (1), feature several spring-loaded stub contacts (19, 20) and/or contact plugs (21,22), all of which are oriented vertically to circuit board (10), and where said strip conductors are connected at least to terminals (23) of magnet coil (5), which are installed on flange (7) of coil module (6).
