Definitions

  • the invention relates to an electromagnetic relay with an excitation coil and a rod-shaped, in the coil body extending approximately along the coil axis, on one of the coil flanges by means of a pivotably arranged, made of insulating material support member mounted on one side, which is rigidly connected to the support member and which forms a working air gap in the region of the second coil flange with at least one pole plate, at least one contact spring being connected to the armature by anchoring in the carrier part made of insulating material and these contact springs or springs located outside the coil and thus at a certain distance from the coil
  • the armature extends or extends parallel to it essentially over the entire coil length and, with its free end (s), cooperates or cooperates with at least one counter-contact element arranged in a basic body.
  • This relay according to the older application has the advantage that the armature movement is transmitted directly to the contact springs by the direct attachment of the contact springs in the insulating support of the armature, so that no actuating slide is required.
  • Such stranded connections are relatively expensive and complex to manufacture.
  • the insulating support of the armature must be stored there by suitable measures on the coil body, which brings with it an unavoidable friction. If the armature should also have a pretension or restoring force, this must be applied by an additional spring.
  • the object of the present invention is therefore a development of the aforementioned relay in such a way that the stranded connections for the movable contact springs can be omitted and at the same time the bearing friction of the armature is avoided.
  • the contact springs in the region of their anchoring in the carrier part each have an extension which is formed in one piece with the contact springs and which - each forming a connecting lug - is fastened in the base body and serves as a resilient mounting of the carrier part.
  • the contact spring movable with the armature and its connecting lug each consist of one part, and this part also takes over the storage of the armature.
  • a stranded wire connection for the electrical connection of the contact spring is thus superfluous, and at the same time the bearing friction of the armature is avoided.
  • the spring bearing can also generate a desired restoring force for the armature without an additional restoring element being required for this.
  • the extension of the contact spring or the contact springs expediently emerges from the carrier part in the region of the armature axis of rotation and forms a fastening part with an integrally formed connecting lug via one or more offsets. It is provided in an expedient embodiment that the fastening part runs at least partially parallel to the spring leg of the respective contact spring.
  • a contact spring is fastened on both sides of the armature in the carrier part, the extensions of the two contact springs emerging from the carrier part offset relative to one another in the direction of the armature axis of rotation.
  • the extension of each contact spring can have a reduced spring section in cross section, which is subjected to bending or torsion during the switching movement of the armature.
  • the invention is explained in more detail using an exemplary embodiment with reference to the drawing.
  • the single figure shows a simplified representation of an armature mounted on a base body for a relay system according to EP-A-72975.
  • the armature 71 shown in the drawing consists of an elongated ferromagnetic sheet and is movably arranged in a coil body (not shown) with the winding 72, which is only indicated schematically. With its free end 71a, it is movably arranged between two pole plates 73 and 74 and forms a working air gap 75 and 76 with respect to these pole plates.
  • the pole plates 73 and 74 are only indicated with their ends. Like the entire magnet system, they can be designed, for example, as in the relay according to EP-A-72975.
  • the armature 71 With its opposite end 71b, the armature 71 is fastened in a carrier part 77 made of insulating material, for example by embedding or inserting it.
  • two contact springs 78 and 79 are also attached, which extend with their spring legs on both sides of the armature 71 and parallel to it and with their free ends 78a and 78b between two counter-contact elements 80 and 81 or 82 and 83 are arranged so that they give optional contact with this.
  • the mating contact elements 80, 81, 82 and 83 are in fastened the schematically illustrated base body 84 in the usual way, for example by embedding or inserting, and each form terminal lugs on the connection side of the base body 84, for. B. 80a, 81a.
  • the contact springs 78 and 79 each form an extension 78b and 79b from their anchoring in the carrier part 77, which leads to a fastening section 78c and 79c running parallel to the contact spring 78 and via their anchoring in the base body 84 each forms a connecting tab 78d.
  • the corresponding connecting lug of the contact spring 79 cannot be seen in the figure.
  • the contact springs 78 and 79 each form a spring bar 78e and 79e. These webs lie in the region of the axis of rotation of the armature 71 and, due to their spring action, exert a restoring force on the armature together with the entire fastening parts 78b and 79b.
  • the contact spring 78 thus consists of its spring leg via its embedding in the carrier part 77 and over the multiple angled and cranked fastening part 78b up to the connecting lug 78d in one piece, so that without an additional element both the electrical power supply and the bearing of the carrier part 77 are included the anchor 71 can be made.
  • the webs 78e and 79e serve as pivot bearings. This also eliminates any bearing friction for the armature 71.
  • the contact springs 78 and 79 could of course be modified with their connecting parts, so that, for example, instead of the webs 78e and 79e subjected to bending stress, torsion webs can be arranged in the axis of rotation of the armature.
  • the armature can be pretensioned into a central position or into a lateral end position by appropriate design and adjustment of the contact springs or their fastening parts.
  • the base body can be designed to accommodate the coil former (not shown) and other elements, for example can also be designed in a suitable manner to accommodate a cover cap.
