Definitions

  • the invention relates to a contact arrangement for a relay with high switching power, in which a movable contact spring is at least opposite a counter contact element, a contact piece fastened on the free end of the contact spring having a high conductivity being connected directly to a connecting line.
  • the object of the invention is to design a contact arrangement of the type mentioned at the outset for use as a changeover contact, a high switching current being able to be conducted via the center contact with little loss without having to use a well-conductive and therefore expensive spring material for the contact spring.
  • this object is achieved in that the contact spring as center contact spring carries a contact piece on both sides, one of which projects beyond the width of the contact spring and the opposite contact piece, and that the connecting line is welded to the protruding part of the contact piece in question.
  • the center contact spring With the design of the center contact spring according to the invention with the one contact piece projecting beyond the spring, it is possible to connect this contact piece directly to a connecting wire, so that the contact spring itself does not carry the switching current and can therefore be made from cheaper spring steel. Also for the opposite, shorter contact piece, the contact spring does not form a large resistance, since the current flows from the connecting wire over the longer contact piece and then through the relatively thin spring with a large cross section.
  • the resistance via the spring can also be reduced by the fact that at least one of the contact pieces has an attachment with which it is directly connected to the other contact piece through a hole in the central contact spring.
  • This configuration of the contact arrangement means that both contact pieces are directly conductively connected to one another, while the extended contact piece is in turn welded to the connecting line, for example a stranded wire.
  • the resistance value of the center contact spring which expediently consists of spring steel of relatively low conductivity, is therefore irrelevant.
  • both contact pieces In principle, it would be possible to equip both contact pieces with an extension, the two extensions being able to engage in the hole in the center contact spring from both sides. However, it is easier to equip only one of the contact pieces with an extension which corresponds approximately to the thickness of the central contact spring.
  • the smaller of the two contact pieces is expediently formed in a rivet shape and inserted with a corresponding extension through the hole in the center contact spring. In this area, the two contact pieces are expediently welded directly to one another and also to the central contact spring.
  • the contact arrangement shown in FIG. 1 is part of a relay, as is generally shown, for example, in the German utility model 83 25 986 with its magnet system.
  • a contact spring 2 which also serves as an armature return spring, is attached to the armature 1 of such a magnet system.
  • the free, cross-sectionally reduced end 2a of this contact spring 2 serves as a center contact spring in an alternating contact arrangement.
  • the contact spring 2 is switchable between two mating contact elements 3 and 4. Each of the two mating contact elements is connected via a connecting tab, e.g. 5, anchored in a base or base body, not shown.
  • Contact pieces 6 and 7 are applied to the mating contact elements as riveted or welded contacts.
  • a further connection element 8 is anchored in the base body, from which a strand 9 leads directly to the end of the contact spring 2a.
  • a contact piece 10 or 11 is welded on both sides, the contact piece 11 projecting beyond the width of the contact spring at its end 2a and also beyond the width of the contact piece 9 and thus a free surface 12 for attachment the strand 9 forms.
  • the switching current is thus conducted from the contact piece 11 directly to the connection element 8 via this copper wire 9.
  • the current to the contact piece 10 can also flow from the contact piece 11 via the thin material of the spring 2 over the entire surface of the contact piece 10 without any appreciable resistance.
  • the two contact pieces 10 and 11 are separated from the same strip material with their different lengths and welded onto the contact spring 2 or its free end 2a from both sides.
  • This strip material of the two contact pieces 10 and 11 consists of copper and is plated with a noble metal layer 13.
  • the contact spring 2 itself is designed as an inexpensive steel spring with sufficient electrical conductivity and good spring properties to achieve the required contact pressure.
  • FIGS. 3 and 4 A somewhat modified exemplary embodiment is shown in FIGS. 3 and 4.
  • the two contact pieces 20 and 11 are applied from both sides to the free end 2a of the contact spring 2.
  • the contact piece 20 has a rivet shape with a shaft or extension 21, which corresponds in length to the thickness of the contact spring 2.
  • This shaft 21 is inserted into a hole 22 of the contact spring 2, while the contact piece 11 cut from a strip material is applied from the other side of the contact spring 2.
  • the two contact pieces lie directly against one another in the region of the hole 22 and are welded together.
  • both contact pieces consist, for example, of copper or a copper alloy and are plated with a noble metal layer 13 or 23. But you could also consist of solid contact material, e.g. B. AgNi 0.15.
