Definitions

  • the invention relates to a small switching relay with increased insulation between the magnet system and contact system for use as a miniature card relay, consisting of a spring bracket, magnet and contact system receiving housing and a cover closing the housing.
  • a small switching relay mentioned at the outset is produced in several embodiments.
  • the disadvantage of all known embodiments is that certain minimum dimensions cannot be undershot.
  • Conventional external dimensions are, for example, 27.9 x 24.7 x 10.4 mm. So far, it was not possible to go below this dimension because, on the one hand, increased insulation was sought and, on the other hand, because of the insulation measures and for constructional reasons, the contact system with the holders for the contact spring was produced separately from the housing.
  • the present invention has for its object to develop a small switching relay of the type mentioned so that it can be used as a card relay, and can be mounted next to each other, for example, in a 5 mm grid.
  • the invention is characterized in that the spring bracket is made of one piece of material with the trough-shaped housing which is open on one side.
  • a trough-shaped spring bracket is present, in which a spring-loaded bracket Magnet system and a chambered contact system are also arranged.
  • the end is a lid that is held in place.
  • the maximum height for this relay in the horizontal version was 7.9 mm.
  • the relay according to the invention is the first high-current small switching relay in an extremely flat design.
  • this relay can also be installed next to each other in a 5 mm grid as the first relay.
  • this relay In contrast to known relays, this relay also has 1 changer version with clearance and creepage distances of more than 8 mm, i.e. so increased isolation. So far, such relays with larger dimensions were only known in the 1 x work version.
  • the relay is designed so that the washproof version (IP 67) has the same dimensions as the open version (IP 40).
  • the spring bracket is made in one piece with the trough-shaped housing that is open on one side, the required miniaturization results.
  • the spring bracket is the mounting element for all parts of the relay, in particular the contact system and the magnet system. If the spring bracket is made of one piece of material with the housing itself, it can be seen from this that a separate arrangement of mounting parts and housings according to the invention is avoided and instead the mounting parts are integrated into the housing itself.
  • the housing is preferably made from a plastic injection molding material, so that the contact system and the magnet system are inserted directly into the housing and fastened there. The pre-assembly outside the housing with corresponding mounting elements is not necessary, since these separate mounting elements would only take up space in an undesirable manner.
  • the magnetic frame is installed by simply inserting the excitation coil with core and yoke into the housing, the armature retaining spring being fastened in a holder fixed to the housing. All parts are only protected against falling out by the cover. In order to reach the 8 mm clearance and creepage distances, the anchor must be embedded in a pocket in the actuating web.
  • the overall construction thus enables automated production.
  • Isolation according to VDE 0110 IGr C / 250-B / 380.
  • Washable version IGr C / 380.
  • the relay according to Figures 1 to 4 consists of a trough-shaped housing 10, which also serves as a spring bracket 1 for holding the magnet system 2 and the contact system 3.
  • the magnet system 2 consists of an excitation coil, in which the yoke and core 8 are formed from a single part in a stamping and bending process and are designed as a U-shaped part.
  • the entire magnet system 2 is only inserted into the housing, the connections 27 penetrating corresponding lateral slots on the housing.
  • the magnet system is therefore only inserted into the housing and is essentially protected from falling out by the cover 4 which is pressed into place on the housing.
  • a further securing of the position of the magnet system 2 results from the fact that an armature retaining spring 11 is present which is clamped in the slot 21 of a holder 12.
  • the holder 12 is integrally connected to the bottom of the housing 10.
  • the armature retaining spring forms the abutment for the armature 13 pivotably mounted on the yoke 8, the rear, free and pivotable end of which is received in a pocket 14 of the actuating web 15. This is done for insulation reasons.
  • the actuating web 15 passes through a narrow opening 19 in the chamber wall 17, which separates the magnet system 2 from the contact system 3 arranged above it.
  • the contact system 3 consists of two switching springs 7a, 7b which, depending on the position of the armature 13, come into contact with the contact spring 7c.
  • the switching springs 7a, 7b are accommodated in corresponding slots 22, 23 of the housing, a plurality of slots 22 and 23 lying one behind the other being provided, which are each separated by a recess 25.
  • the contact spring 7c is likewise guided in a slot 24 in the housing 10 and also extends through a recess 26. The position of the springs 7a, 7b, 7c is then secured in the region of the recesses 25, 26.
  • the springs 7a, 7b, 7c are led to the outside with connections 9a, 9b, 9c, it being essential that the connections pass through the cover 4 in the horizontal configuration and the cover is provided with conically tapering openings 5 in the area of the connections, and has pockets 28 of recessed diameter on the outside.
  • the conical openings 5 and the pockets 28 reference is made to the German patent application P 33 19 329.0, which goes back to the same applicant. The disclosure there is intended to be encompassed and included in full by the disclosure herein.
  • a rib 16 is formed on the underside of the cover 4, which abuts directly on the chamber wall 17 and thus ensures a double separation from the contact system 3 to the magnet system 2. It is also important that the rib 16 extends to close to the bottom of the housing 10 according to Figure 2.
  • the rib 16 is provided with an angled portion 20, which still partially encompasses the excitation coil of the magnet system 2 and overlaps the armature holding spring 11.
