Definitions

  • the invention relates to a relay assembly with a socket, which has a flat bottom part with ribs formed on the top and with guide channels running through to the bottom, with a bobbin having a winding, a core, a yoke and an armature and having two flanges with projections formed on the flanges resting on the bottom part, at least one of the flanges having a receptacle for at least one fixed mating contact element, and with plug elements for the mating contact element, for winding connections and for at least one, carried out in the guide channels of the base to the underside of the bottom part movable contact element coupled to the armature.
  • a relay with a comparable structure on a base is known for example from DE-OS 34 28 595. There it is a relay in which the base occupies only the area below the magnet system in a conventional manner and in which the connection elements for the excitation winding and for the contact elements all emerge from the base in one area below the magnet system.
  • the known relay with the flat plugs in the plug-in base can thus either be inserted into a correspondingly adapted socket, which in turn must have individual wiring of the connections, or the individual flat plugs of the relay can be contacted with individual lines via cable lugs.
  • Such relays are not designed for connection to multi-core cables with a multi-pin connector.
  • relays of the type mentioned in various areas for example in automotive engineering
  • a relay as a switching module with a control arranged remotely therefrom on the one hand and with one or more consumers (s), for example a pump motor or a lamp group, which are in turn arranged elsewhere.
  • consumers for example a pump motor or a lamp group
  • the object of the invention is to design a relay assembly of the type mentioned at the beginning with plug connections so that the control on the one hand and the consumer on the other hand can each be connected by means of conventional multipole plug connectors, with as little and as simple as possible connecting elements between the relay system and the respective plug elements required are.
  • the base forms a relay chamber provided with all-round side walls at the top of the base part and at least two connector shafts for receiving a multipole connector each at the bottom of the base part, that the mating contact element with its molded-on connector element in a first It is guided that at least one first conductor rail arranged on the bottom of the relay chamber and connected to the movable contact element is guided into a second connector shaft with a connector element molded downward, and that at least one second conductor rail is provided, each with a connector element molded downwards each of the two connector slots is guided.
  • the inventive design of the relay module makes it possible to couple the control of the excitation voltage and the voltage source for the load circuit via the first connector slot by means of a multi-pin connector, while the consumer is coupled separately via the second connector slot via its own multi-pin connector. While in conventional arrangements of the consumers, the voltage source must be connected externally in series with the two contact connections of the relay, the two poles of the voltage source can be coupled here via two plug connections in the first plug shaft.
  • the connector slots can be round or rectangular, depending on the cable connector used, or can have any other shape.
  • the plug connections for the field winding are expediently guided together with the connections of the voltage source via the first plug shaft.
  • additional bridge rails with plug elements are arranged in both plug shafts in the relay chamber.
  • sensor signals that are supplied by the consumer via the consumer cable can be looped through the relay module to the control cable and thus to the controller without further measures, and they are not connected to the actual relay.
  • a further plug connection can be provided in the other plug shaft, for example for test purposes, preferably in the first plug shaft, which is connected to the controller.
  • the current conducting rails or additional soldering support points in the relay chamber have notches for receiving connecting wires of additional components, such as diodes.
  • additional components such as diodes.
  • diodes can, for example, be connected in series or in parallel to the winding or also in parallel to the consumer circuit.
  • other electronic or electromechanical components can also be accommodated in the relay chamber, as well as additional relay systems.
  • the relay module shown in FIGS. 1 to 3 has a base 1 as a base body with an essentially flat base part 2, on which two connector shafts 3 and 4, which are cylindrical in the example, are formed at the bottom.
  • two connector shafts 3 and 4 which are cylindrical in the example, are formed at the bottom.
  • plug shafts protrude from the top through the bottom part led flat connectors, which will be described later in detail. They are connected by inserting cable connectors (plug couplings) with a respective cable and thus with a remote module, for example with a controller or with a consumer.
  • the connector slot 3 is designed for a seven-pin connector, the connector slot 4 for a four-pin connector.
  • the rectangular bottom part 2 of the base 1 is provided with all-round molded side walls 5, which form a relay chamber 6 which is initially open at the top.
  • This relay chamber can be closed with a cap 7, which snaps into recesses 8 of the side walls 5 with not visible locking lugs.
  • the bottom part 2 has ribs 9, which serve the intermediate guide shafts and grooves for holding a magnet system as well as conductor rails or additional components.

  • a parallel diode 31 can also be soldered between the notches 26a and 27a.
  • a parallel diode 32 is provided between the two conductor rails 24 and 25, which is clamped or soldered in corresponding notches 24d and 25d of these conductor rails.
