Definitions

  • the invention relates to an electromagnetic power relay with a contact set which has at least one fixed mating contact element and a movable contact element in the form of a leaf spring clamped on one side, and with a magnet system, the armature of which acts on the latter via a slide which can be moved approximately perpendicular to the longitudinal extension of the leaf spring, around the latter to move from a rest position to a working position.
  • Such a power relay is described for example in DE 29 12 800 A1.
  • To actuate the center contact spring there is a card-shaped slide which engages with a parallel end edge on the broad side of the contact spring.
  • the contact spring is pivoted evenly around its clamping point.
  • the object of the invention is therefore to enable safe switching with a given spring cross-section and given dimensions of the spring length and the magnet system.
  • this object is achieved in that the slide acts on the broad side of the leaf spring off-center only in an edge region.
  • the construction according to the invention thus actuates the leaf spring asymmetrically, which leads to torsion of the leaf spring during the switching process, as a result of which a reduced spring rate comes into effect.
  • a weaker and smaller magnet system can be used, which nevertheless switches the contact spring safely, or a magnet system can be used with the same size that requires less power, i.e. is more sensitive and thus electrically cheaper is controllable.
  • Generous manufacturing tolerances can also be permitted, which makes manufacturing cheaper.
  • the torsion movement also increases the burn-off safety or enables a larger contact opening. Another advantage of this torsional movement is that welded contacts are more easily torn open. This effect is known in principle, for example from EP 0 326 116 A1.
  • the contact piece of the contact spring is arranged offset from the central axis of the contact spring opposite to the actuation point.
  • the slider itself can be in the form of a card, the end of which faces the leaf spring is approximately U-shaped, the two outer legs of the U-profile engaging in guide cutouts in both edge regions of the leaf spring and the central part of the U-profile only on one side of the leaf spring attacks.
  • the middle part of the U-profile, following an outer leg, can have a short actuating section running parallel to the leaf spring surface and then an edge section cut away from the leaf spring.
  • 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, which will be described later.
  • the contact spring 10 in turn works together with a fixed counter-contact element 11.
  • An NC contact is shown in the example.
  • a different arrangement of the counter-contact element can of course also provide a make contact or a changeover contact.
  • 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 counter-contact element 11 are thus essentially perpendicular to the bottom of the base body and run approximately parallel to one another, overlapping with their contacting areas. As far as the respective mutual ge distance to their connecting parts, 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 of the base body 1, both of which extend along the outer wall of the base body in the direction of the front side 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. Outside the housing then solder pins 20 and up flat tabs 21 are formed on the connecting rails 11 a and 12 a.
  • This slide consists of a card and has an essentially U-shaped plan with which it encompasses the partition 3. It is coupled to the armature by a first arm 91, while the second arm 92 is in engagement with the contact spring 10.
  • This second arm 92 itself is provided with an approximately U-shaped profile, a first outer leg 93 and a second outer leg 94 engaging in guide cutouts 10a and 10b of the contact spring 10 (see FIG. 3).
  • the middle part of the actuating arm 92 forms a short actuating edge 95 which adjoins the outer leg 93 and which bears on the contact spring 10, while the edge 96 slants backwards laterally in order to enable free torsion of the contact spring 10.
  • the contact piece 10c of the contact spring like the corresponding contact piece 11c of the mating contact element 11, is arranged offset from the central axis of the contact spring opposite to the actuating edge 95. As a result, the effect of spring torsion comes into its own particularly well.
