Definitions

  • Such a relay is known for example from EP 0 147 681 B1.
  • the solder and plug connections are in a straight extension of the connecting rails, that is to say in the plane of the outside of the housing. It is therefore not possible to place such a relay directly next to a similar relay or another component with open metal parts on a circuit board, since the insulation distances required for high-voltage connections, i.e. air and creepage distances, are not guaranteed.
  • the object of the invention is to improve a power relay of the type mentioned at the outset in such a way that the connecting rails in the housing allow the best possible utilization of the housing width for the dimensioning of the contact elements, but that the connecting parts located outside the housing have a sufficient insulation distance from the outer sides of the housing or have extensions.
  • the contact connection elements should be anchored as well as possible in the base body, so that the adjustment of the contact elements to one another is not changed when plugging in or removing cable connections.
  • the fastening lugs inside the pockets can be bent inwards via a shoulder.
  • a corresponding recess on the outside of the pockets makes these fastening lugs easily accessible for a tool.
  • the anchoring of the connecting rails in the pockets also takes place via fastening lugs which are already in the indented plane of the end sections, so that these fastening lugs, which must be accessible for installation from the side, have the required insulating distance from the side wall.
  • the relay shown in FIGS. 1 to 3 has a base body 1 with a base part 2 and an essentially vertical partition 3, with which a magnet system space 4 is separated from a contact space 5.
  • the magnet system has a coil 6, a yoke 7 and an armature 8, the switching movement of which is transmitted to a contact spring 10 via a slide 9; the contact spring 10 in turn works together with a fixed counter-contact element 11.
  • An NC contact is shown in the example. By a different arrangement of the counter-contact element, a closer can of course also be provided.
  • a spring support 12 for the contact spring 10 is inserted from one outside into a receiving slot 13 of the base body, fixed with a tab 14 and additionally anchored by interlocking a fastening pin 14a.
  • the mating contact element 11 is inserted into a corresponding receiving slot 15 of the base body and additionally anchored by means of a tab 16.
  • the contact spring 10 and the mating contact element 11 are thus essentially perpendicular to the base of the base body and run approximately parallel to one another, overlapping with their contacting areas. As far as the respective mutual distance to their connecting parts allows, the contact spring 10 and the mating contact element 11 extend over a large part of the width of the relay. They therefore have a large cross section for carrying high currents.
  • connection rail 12a or 11a in the region of the base 2 of the base body 1, both of which extend along the outer wall of the base body in the direction of the end face 17 of the relay. They thus run between the base body 1 and the side walls of a cap 18, which together with the base body forms the housing.
  • an additional cover plate 19 is provided on the underside for sealing.
  • connection end sections 11b and 12b are then solder pins 20 downwards and flat plugs 21 upwards molded.
  • the bend sections 11c and 12c lie in pockets 22 formed on the end face of the cap 18, which are open at the top and bottom and have slots in their peripheral walls from below into which the connecting rails 11a and 12a enter when the cap is fitted.
  • the connecting rails also have fastening lugs 11d and 12d, which are cut free from the offset areas 11c and 12c and thus lie in the plane of the end sections 11b and 12b.
  • Appropriate wall recesses 22a allow these upwardly projecting fastening lugs 11d and 12d to be accessed from the outside for tools and can thus be bent inwards over a shoulder 22b of the respective pocket after the cap 18 has been fitted, as a result of which the connecting rails 11a and 12a are securely anchored will.
  • these fastening lugs 11d and 12d which are accessible from the outside, also lie at an insulation distance from the outside of the housing such that the required air and creepage distances to a neighboring component are guaranteed in any case.
