Definitions

  • the invention relates to an electromagnetic relay with a coil body serving as a support for the relay, an angled yoke, the first leg of which is coupled to a first pole end of a coil core and the second leg of which forms a bearing edge for a flat armature which forms a working air gap with the second pole end of the coil core forms, wherein a contact spring connected to the armature extends beyond its free end into a molded contact pocket on the coil former and connects there as a contact bridge, at least in a switch position, in alignment with one another, with the bearing axis of the armature or the contact spring being perpendicular to the exclusion plane of the relay .
  • the object of the invention is therefore to provide a relay of the type mentioned, in which a bridge contact arrangement is formed with as few and simple parts as possible, in which the contact pressure is the same at all contact points and which without design changes by corresponding use of contact elements as a bridge closer , can be designed as a bridge opener and as a bridge switch.
  • this object is achieved in that the two counter-contact elements carrying both the counter-contact pieces and the exclusion parts (16c, 17c) are flat plates which are anchored in the carrier and are parallel to one another and in a common plane, and in that the counter-piece (16b) carries End of the one counter-contact element is a cross leg lying in the common plane and carrying the counterpart (17b) carrying the end of the other counter-contact element.
  • the two mating contact elements Due to the angular shape of the first mating contact element designed as a flat section, it is possible to arrange the two mating contact elements to be contacted jointly by the bridge contact spring with the required distance and still arrange the contact points of the two mating contact elements so that both are at the same distance from the pivot axis of the bridge contact spring and thus get the same contact pressure.
  • the relay shown in FIGS. 1 to 3 has a coil body 1 with a winding 2, which is applied between the flanges 3 and 4.
  • An iron core 5 is arranged in the coil body 1 along the coil axis and is connected at one end 5a to the first leg 6a of an angular yoke 6.
  • the other end 5b of the core serves as a pole face and forms a working air gap with an armature 7, which lies with an extension 7a in a recess 6c of the second yoke leg 6b and is mounted on a bearing cutting edge 6d.
  • the armature By means of a return spring in the form of a helical spring 8, the armature is pulled into its rest position, while when the relay responds, it is attracted to the core end 5b against the force of the spring 8 and thereby switches the bridge contact spring 9 attached to it.
  • the relay corresponds to a known structure.
  • the contact arrangement is arranged in a contact pocket 10, this contact pocket being formed in one piece with the coil former by an extension 11 on the coil former flange 4.
  • Four receiving slots 12, 13, 14 and 15 are provided in the contact pocket for receiving counter-contact elements.
  • only the receiving slots 12 and 13 are equipped with counter-contact elements 16 and 17, while the opposite receiving slots 14 and 15 remain free.
  • the relay shown is thus designed as a bridge closer, since the rest side of the bridge contact spring 9 is not equipped.
  • the receiving slots 14 and 15, which are not used in all embodiments, are expediently closed by thin mold partitions, which are only pierced through the inserted connecting pin of the mating contact elements when these receiving slots are fitted.
  • the short counter-contact element 17 carries a contact rivet 17b at its free end 17a, while the longer counter-contact element 16 has a cross leg 16a at its free end, which projects beyond the free end 17a of the other contact element and carries a contact rivet 16b in the area above the second counter-contact element 17 .
  • the two counter-contact elements 16 and 17 are thus entirely in one Level, with their two contact rivets 16b and 17b being at the same distance from the pivot axis of the bridge contact spring 9, so that when the armature 7 is tightened, both contact rivets 16b and 17b simultaneously come into contact with the contact rivets 9a and 9b of the bridge contact piece 9c and through the torsional contact spring 9 with the same contact pressure.
  • the connecting pins 16c and 17c of the mating contact elements 16 and 17 are designed in such a way that they are as far apart as possible from one another.
  • a partition 18 is provided in the contact pocket to increase the insulation strength between the mating contact elements and to improve the rigidity of the carrier.
  • the receiving slots 14 and 15 could also be provided with counter-contact elements 16 and 17, which would form a normally closed contact with the contact spring 9, so that the relay as a whole would be designed as a bridge switch.
  • the bridge contact spring 9 only needs to conduct the switching current with its bridge contact piece 9c at the free end, so that it can also be attached to the armature 7 in an insulated manner.
  • the bridge contact piece 9c and its fastening end 9d In the area between the bridge contact piece 9c and its fastening end 9d, it has a web 9e reduced by incisions in cross section, the width of which is smaller than the distance between the contact rivets 9a and 9b.
  • This narrow bar thus acts as a torsion bar, through which different contact openings of the upper and lower contacts can be compensated in order to maintain the same contact forces.
  • the contact spring In the region between the fastening end 9d and the web 9e, the contact spring has a trapezoidal section, as a result of which the elastic deflection is improved. In this trapezoidal section, a pretensioning bend 9f is also provided, which increases the contact forces and improves the burn-off safety.
  • the contact spring 9 is rounded on its outer edges in the region of its bridge contact piece 9c. In addition, it has at its free end a projecting tab 9g, which in the embodiment shown strikes a stop lug 19 and thereby defines the rest position of the armature.
  • the tab 9g can be cut off.
