Definitions

  • the invention relates to an electromagnetic rotary armature relay with an insulating material, carrying a field coil supporting body, in which contact connection elements are anchored and on which an armature is rotatably mounted approximately centrally, the armature having at least one elongated ferromagnetic rod, the free ends of which have the pole ends of a coil core form working air gaps and which carries in its central region a covering made of insulating material containing bearing elements.
  • a rotary armature relay of this type is known for example from DE-OS 27 23 430. Depending on the special design of the magnetic circuit and the armature, this relay can work with or without permanent magnets, unpoled or poled, monostable or bistable. Such rotating armature relays are generally relatively sensitive and largely insensitive to impact on overall rin g he response performance and because of the central armature bearing.
  • the contacts are actuated via actuators which are connected directly or indirectly to the armature and act on movable contact springs, which in turn are anchored in the base body together with the fixed mating contact elements.
  • the object of the invention is to develop a rotary armature relay of the type mentioned in such a way that the contacts have the largest possible friction paths, while on the other hand other friction losses during armature movement or during contact actuation are largely avoided and the excitation power of the relay is thus kept small.
  • this object is achieved in a relay of the type mentioned at the outset in that contact springs, which cooperate with counter-contact elements anchored in the base body, are fastened in the insulating sleeve of the armature and run parallel to the ferromagnetic rod or the ferromagnetic rods.
  • the movable contact springs are thus directly connected to the armature, in such a way that they extend laterally next to the ferromagnetic rods forming the actual armature and thus also laterally next to the axis of rotation of the armature. This means that the center of motion of the movable contact springs does not coincide with their clamping point and that the resulting relative movement creates a noticeable friction at the contact points.
  • the contact springs are damped when switching, but on the other hand there is no friction loss due to a separate actuating slide, since the contact springs are firmly clamped to the armature.
  • a contact spring is provided on both sides of the ferromagnetic rod or ferromagnetic rods, which is fastened with its central portion in the insulating jacket and with its two free end portions can be brought into contact with one or two mating contacts.
  • two contact springs can also be provided on both sides of the ferromagnetic rod or the ferromagnetic rods, each of which extends from its fastening point in the insulating casing to approximately the free end of the armature.
  • four movable contact springs are obtained which are insulated from one another and which, depending on the design of the mating contact elements on the base body, can form an opener, a closer or a changeover contact.
  • the contact springs fastened in the insulating material covering of the armature can each be connected to connection elements anchored in the base body via flexible conductors, that is to say via strands or flexible metal tabs.
  • the contact springs, which are fastened in the insulating material covering of the armature each act as contact bridges between two mating contact elements without their own connection elements. In this case, the flexible connection from the base body to the movable anchor can be avoided.
  • the armature which can be provided, for example, as a so-called H-armature with one or more permanent magnets, can be journal-mounted on the base body in a known manner, bearing elements, i.e. journals or bearing bores, being able to be molded into the insulating material covering of the armature.
  • the armature can, however, also be held on the base body by means of resiliently deformable bearing elements be. It is particularly advantageous if extensions are formed on the contact springs fixed in the insulating material and are anchored to the base body as bearing elements for the armature.
  • the contact springs can each be integrally formed with the bearing elements of the armature and the connecting pins anchored in the base body. As a result, the relay can be manufactured with very few parts.
  • Fig. 1 shows a relay with a base body 1, which may for example have the shape of a tub open at the bottom.
  • a non-visible coil is accommodated in the base body, the rod-shaped core 2 of which, with its free ends, forms working air gaps with an armature 3 mounted on the base body.
  • the armature 3 consists of two elongated ferromagnetic rods 4 and 5, the ends 4a, 4b and 5a and 5b of which are each angled downward in a U-shape and with their free ends each enclose a free end of the core 2.
  • the ferromagnetic rods or yokes 4 and 5 are held together by an insulating jacket 6.
  • a bearing bore 7 is formed in this insulating material sheathing, by means of which the armature is rotatably mounted on a pin 8 of the base body.
  • Two permanent magnets 9 and 10 are arranged between the ferromagnetic rods or yokes 4 and 5, through which the relay is polarized.
  • two contact springs 11 and 12 and 13 and 14 are embedded or fastened on both sides, which are carried along by each armature movement and accordingly optionally have contact with the mating contact elements 15, 16 anchored in the base body 1.
  • the mating contact elements is provided on the underside of the base body 1 with a connecting pin 15a, 16a, etc.
  • connection elements 23 and 24 are anchored in the base body 1 with corresponding connection pins 23a and 24a for the movable contact springs 11 and 12 as well as corresponding, not visible connection elements for the contact springs 13 and 14.
  • Additional pins 25 and 26 are provided for the coil winding.
  • the movable contact springs 11 and 12 are connected to their connecting elements 23 and 24 via flexible strands 27 and 28.
  • the contact springs anchored in the insulating material cover 6 serve as bridge contact elements without their own connections and, for example, connect two mating contact elements to one another in each switching position, for example the contact elements 15 and 18 in a switching position and the contact elements 16 and 17 in the other switch position.
  • the contact springs 11 and 12 would be formed as a single coherent part in the insulating jacket.
  • the relay according to FIG. 1 can be closed, for example, with a cap 29, which is only indicated in the drawing.
  • a cap 29 can be tightly connected, glued or welded to the base body in a known manner.
  • FIG. 2 shows a schematic representation of a modified embodiment of the rotary armature relay according to the invention.
  • An armature 32 with an elongated ferromagnetic rod 33 is arranged on a base body 31, the two ends of which form working air gaps with respect to core pole plates 34 and 35, and 36 and 37 arranged in pairs. These are part of one.
  • Magnet system not further shown with two U-shaped core elements which carry a coil and enclose a permanent magnet between them. Such a magnet system is described for example in German patent application P 31 40 226.7.
  • the armature 32 has an insulating material covering 38 in its central part, in which movable contact springs 39, 40, 41 and 42 are fastened by insertion or embedding. These movable contact springs interact, for example, with counter-contact elements 43, 44, 45 and 46 anchored in the base body 31, wherein changeover contacts could of course also be formed with further mating contact elements, not shown.
  • the armature is not journal-supported, but rather spring-supported via extensions 39a, 40a, 41a and 42a of the contact springs 39, 40, 41 and 42.
  • These extensions 39a, 40a, 41a and 42a are anchored in the base body 31 and at the same time form with integrally formed connecting pins 39b, 40b etc. for the movable contact springs.
  • These extensions can also be meandering in order to enable better movement of the armature. This results in a friction-free anchor bearing, combined with the advantages of the first embodiment.
