Definitions

  • the present invention relates to a relay at least two contact units, which by a insulating septum are separated, each Contact unit has at least two contact members, from at least one each parallel to the partition is aligned elongated contact spring, the contact end to make or break a contact parallel to Partition is movable, with an actuator for Moving the contact ends and with plug connections for Connect the relay, which plug connections in are pluggable perpendicular to the partition.
  • relays are lying on a circuit board stuck because the plug connections are in the direction of the smallest Dimension of the relay are pluggable.
  • There is a demand for lying relays because relays for the most part belong, which are arranged on boards. So now Boards should be arranged as closely as possible , it is desirable for relays to be as low as possible Have overall height, i.e. as little of the board as possible stand out. Relays are also preferred, which if possible take up little space.
  • An embodiment of a relay with both is preferred Features, since its plug connections within the by the Length of the contact springs determined dimensions of the relay fall and at the same time the distances between the Plug connections can be dimensioned so easily can that the distances of 10 mm for safe separation are adhered to.
  • the contact units on this side and beyond the This can result in a diaphragm facing each other exactly achieved that the connecting parts are shaped as Z. are and have such an offset that they are on the Plug-in connection side of the partition exactly between the pass through electrically conductive parts. So that Connecting part in the support part or through the partition can be pushed through and in a clamping groove of is held here, it is preferred that the contact unit on one side of the partition towards the contact unit on the other side of the Partition parallel to the partition and approximately perpendicular to the length of the contact springs is arranged offset and that Connection part is flat. At this move Arrangement of the contact units can be very simple designed connecting parts in the plane of Contact springs can be passed through the partition to between the electrically conductive parts of the to reach through the plug connection-side contact units.
  • the plug-in connections which are used for the Contacting opposite end of the contact springs are arranged passed through the partition. Also the reverse is possible, namely that through the Partitions guided connecting parts on about one perpendicular to the center plane of the contact springs the partition, between the plug connection side electrically conductive parts through and finally through the housing is guided and the others, plug connection side plug connections directly at the Contacting opposite end of the contact spring only exit through the housing wall.
  • the Contact springs are movable between the Contact springs with increasing distance from their that movable contact end opposite fixed end less space for the passage and isolation of the Connection parts available. That's why it's compact Construction the claimed implementation of the connecting parts preferred near the fixed end.
  • the relay housing consists of a cover and a Bottom part, which is the contact elements Enclose the partition and the actuator, the Bottom of the bottom part is arranged parallel to the partition and has openings for the plug connections, then advantageous those that pass through the partition
  • Connecting parts on the bottom of the partition each with a collar connected to the partition and one with collar connected to the bottom part at least partially surround.
  • a collar around the is expedient arranged around the other so that the creepage distances and clearances between those with the contact links on one side connected parts and with the contact members of the parts connected to the other side at least one specific, have a value set by the standards.
  • the inner one Collar is expediently arranged on the same part to which the plug-in contact units are attached are. If the plug-in contact units on Bottom part are attached, the inner collar is advantageous on the bottom part, but if all contact units on the Partition are arranged on the partition.
  • the slide advantageously has two through a slot separate elongated, arranged in the same plane Tiles on a jetty. These plates are engaged with the extreme ends of the contact springs and the web in engagement with the actuator.
  • the tiles can Slots for all variants of the switching arrangements Have contact units when the to be moved Contact springs are a little longer than the others Contact springs.
  • the partition is perpendicular to the platelets arranged in the slot between these, and one in Cross-section T-shaped cover is with the transverse surface parallel to the plates between these and the housing arranged and inserted with a comb perpendicular to the transverse surface in a groove in the septum so that the platelets in the held with the contact springs engaging position are and also the air and creepage distance between the through the partition separate contact units at least one has a certain measure.
  • This enables a very simple one Assembly of the contact units on the partition.
  • the Contact springs are also with the greatest possible leverage guided, which requires small forces to the springs to move.
  • the contact units on both sides are advantageous the partition on the partition or on one too Carrier part forming the partition. This can do that Part of the interior of the relay with high precision can be put together, which is only with the Housing needs to be protected. This is all the more true to when the actuator in this support member is insertable.
  • the tilt axis is advantageous of the toggle anchor arranged at that pole that the Movable contact ends of the contact spring near pole opposite. This means that, at most, it is above one Slider, the contact springs moving lever of the tilt anchor the length of the magnetic core is available. Therefore, the lever pulled or released by the core Kippankers have a short path, for which a smaller one Magnetic force is needed. Therefore, the magnet can be smaller be designed. It also becomes the appropriate one Dimension of the relay housing only by the length of the Contact springs determined. The coil and the contact springs moving levers of the tilt anchor do not need any additional Expansion of the housing over this by the contact springs conditional dimension.
