Definitions
- the invention relates to an electromagnetic rotary armature relay according to the first part of patent claim 1.
- a rotary fan relay with a conventional design is known for example from DE-A-2 723 430.
- this relay can work with or without permanent magnets, unpoled or poled, monostable or bistable.
- Rotary armature relays of this type are generally relatively sensitive with low response power and, due to the central armature mounting, are also largely insensitive to shock.
- 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 friction of the armature in its mounting and in particular the friction between the slide and the movable contact springs should not be neglected, while on the other hand the movable contact springs, which are only moved about their clamping point, have practically no friction at their contact points.
- EP-A-0 038 727 also describes a rotary armature relay according to the first part of claim 1, in which a certain friction is generated on the contact surfaces for self-cleaning, so that the disadvantages described above are partially eliminated.
- the rotary armature relay described there is designed for the switching of high-voltage current, which is associated with a voluminous and relatively complicated design.
- a U-shaped yoke carries two coils there, and on this yoke arrangement the rotary armature is mounted, which has an insulating sleeve and carries contact springs attached to the sides of this insulating sleeve.
- the base body there consists of a vertically standing plate in which the mating contact elements are anchored.
- the magnet system is attached to a transverse plate, the armature being mounted between this transverse plate and a further, removable part.
- the armature is thus asymmetrically mounted with respect to the base body.
- the contact arrangement is also not designed symmetrically. This results from the fact that the two bridge contact springs on the armature only protrude on one side and interact on one side with fixed counter-contact elements. This results in an asymmetrical load in the bearing, which also increases the friction and excitation power of the relay.
- the known relay is only intended for use with bridge contacts; these are advantageous when used for higher voltages, but disadvantageous for switching very low currents because of the two contact resistance in the circuit.
- the known construction is not readily applicable to small relays for switching small voltages.
- FR-A-1 599 391 shows a device on a generator for protection against reverse polarity; this has a kind of armature, which itself also carries two coils and, depending on the current direction, occupies one or the other position.
- Suggestions for the design of a rotary armature relay of the type mentioned at the outset cannot, however, be taken from this document, since neither switching of external circuits is provided nor is there any comparable structure of a base body and a coil with a core separated from the armature and shown on the base body becomes.
- the object of the invention is to provide a rotary armature relay according to the first part of claim 1, in which, in a known manner, the contact springs are attached directly to the insulation of the armature, but which is advantageously further developed for use as a low-current relay, with friction losses during armature movement are largely avoided and the excitation power of the relay is kept small and the relay is formed with as few parts as possible.
- the contact springs located on one longitudinal side of the armature are each connected in the area of the embedding to form a contact spring, which is fastened with its central section in the insulating material sheath and can be brought into contact with a mating contact element with its two free end sections is.
- 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 a break contact, a make contact or a changeover contact.
- the contact springs fastened in the insulating material covering of the armature are connected to an associated connection element in the base body via a flexible conductor element, that is to say via a wire or a flexible sheet metal tab.
- the armature which can be provided, for example, as a so-called H-armature with one or more permanent magnets, can be in a known manner be journal-supported on the base body, it being possible for bearing elements, that is to say journals or bearing bores, to be formed in the insulating material covering of the armature. To avoid bearing friction, the armature can, however, also be held on the base body via spring-deformable bearing elements. It is particularly advantageous if extensions are integrally formed as spring-deformable bearing elements on the contact springs fastened in the insulating material covering and anchored in the base body.
- 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 base body In the base body there is housed an invisible coil, 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 enclosing a free end of the core 2.
- the ferromagnetic rods 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 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.
- Each of these 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 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 a magnet system (not shown) with two U-shaped core elements which carry a coil and enclose a permanent magnet between them.
- a magnet system is described for example in EP-A-0 077 017.
- the armature 32 has an insulating material covering 38 in its middle part, in which movable contact springs 39, 40, 41 and 42 are fastened by insertion or embedding. These movable contact springs cooperate, for example, with mating contact elements 43, 44, 45 and 46 anchored in the base body 31, wherein, of course, changeover contacts could 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 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.
