Definitions

  • the present invention relates to a polarized flat relay according to the preamble of claim 1.
  • Such a relay is known from DE-OS 35 20 773.
  • the armature extending in the longitudinal direction of the coil is designed as an approximately H-shaped plate and is pivotably mounted above the coil system.
  • the cross slide is coupled with the armature with play.
  • Permanent magnets are arranged in the armature plate, the magnetization of which extends in the longitudinal direction of the coil.
  • the yoke is guided with the longitudinal leg through the coil core, protrudes on both sides and protrudes into the recesses of the H-shaped armature.
  • the armature is pivotally mounted within the coil core.
  • a polarized flat relay with thin dimensions in the vertical direction and a contact unit provided laterally on the coil arrangement in plan view is known from EP-PS 0 117 451.
  • the armature is designed as a pivotable frame, which comprises the coil arrangement and is pivotably mounted in the center of the coil arrangement via pins arranged laterally there.
  • the permanent magnets are arranged in the area of the pegs, that is to the side of the coil arrangement, and the contact units are attached even further outside.
  • the relay thus becomes relatively wide and has the shape of a square when viewed from above.
  • EP-PS 0 118 040 an elongated relay of small dimensions with a construction height corresponding essentially to the height of the coil arrangement is known, in which the armature is also pivotably arranged in the hollow coil core, protrudes on both sides at the front and on one or both sides in the Gap between two pole plates.
  • the contacts are integrated in pole pieces.
  • the present invention is concerned with the task of designing a relay of the type mentioned at the outset in such a way that with a small installation space, in particular a low installation height, a high tightening force is obtained with the lowest possible output.
  • the relay should be easy to assemble and still consist of the simplest possible parts that are easy to manufacture.
  • the relay should also be designed to be wash-tight and to be surface-contactable in OMD technology without increasing the overall height.
  • the characteristics indicated in the indicator 1 In the embodiment according to the invention there is no tiltable or pivotable anchor, the storage of which must always be designed to be relatively complex.
  • the legs of the yoke lie flat on the coil, so that only little space is required on the side, and due to the lateral arrangement of the legs, the overall height can essentially correspond to that of the coil, so that a low overall height can also be maintained.
  • connection pins 6 protrude with connections 7 through openings in the base part 1 to the outside.
  • a magnetizable core 8 of a magnet system is arranged in the hollow coil core 3, in particular inserted or pressed in.
  • the core 8 is preferably circular in cross section.
  • a U-shaped yoke 10 formed from flat material is fastened with its base 11 to the core end 9 protruding from the coil flange 5.
  • Its flat legs 12, 13 run in the plan view in the direction of the coil longitudinal axis L laterally along the coil 4.
  • the free leg ends 14, 15 of the legs 12 and 13 and the free core end 16 of the core 8 protrude beyond the coil flange 5 opposite the former coil flange 5 17 beyond.
  • a cross slide 20 is mounted transversely displaceable perpendicular to the longitudinal axis L of the coil. This is provided with two continuous openings 21 extending in the direction of the longitudinal axis L of the coil.
  • a pole plate 22 made of magnetizable material is held with one end part, e.g. pressed in, glued in or injected, etc.
  • the transverse web 20 also has a transverse slot 24 on the outer wall 23, which extends from one opening 21 to the other.
  • a permanent magnet 25 is inserted in the transverse slot 24, e.g. pressed and / or glued in that one of the magnetic poles abuts a pole plate 22.
  • the two pole plates 22 are therefore oppositely magnetically polarized.
  • the distance A between the core end and the respective leg end 14 or 15 is equal to the thickness D of a pole plate 22 plus the switching stroke H and the clear width between the two pole plates 22 is equal to the width B of the core end 16 plus the switching stroke H.
  • pole plates 22 and the permanent magnet 25 therefore form the armature of the magnet system of the relay, which is fixed in position by means of the cross slide 20.
  • the cross slide 20 has at the lateral ends a closed slot 26 or one which is open upwards or downwards.
  • a contact spring 27 is guided into each slot 26.
  • the contact springs 27 carry a double contact 28, each of which faces a fixed contact piece 29, 30.
  • Each of these contact systems 28, 29, 30 forms a changeover contact and, depending on the switching position of cross slide 20, one contact is closed and the other is open.
  • the contact spring ends 31 preferably project beyond the contacts 28 and into the slots 26. This results in a simple assembly of the cross slide 20 from the front of the relay.
  • the contact springs 27 run laterally at a distance from the legs 12, 13 of the yoke 10 and are fastened in the region of the coil flange 5 opposite the cross slide 20 to a contact pin 32 which protrude through the base part 1 with the connections 7.1.
  • the contact pieces 29, 30 can be contacted from the outside via corresponding contact pins by means of connections 7.2 and 7.3 which project through the base part 1.
  • a preferably cup-shaped cover part 33 can be plugged onto the base part 1.
  • the edge 33.1 of the same expediently projects beyond the outside 1.1 of the base part 1 to such an extent that the space formed can be poured out with a sealing compound 34, for example on the basis of self-curing synthetic resin.
  • the cover part 33 advantageously also serves to fix the position of the cross slide 20, in that, for example, the inside of one end wall 33.2 acts as the front end face and the inside of the cover top 33.3 forms the upper limit.
  • position fixing approaches 1.2 or 33.4 can be provided on the base part 1 and / or on the cover part, which allow only a transverse displacement of the cross slide 20.
  • the height of the cross slide 20 expediently corresponds almost to the clear width between the inside of the lid top 33.3 and the inside of the base part 1.
  • a further advantageous embodiment of the invention consists in that a wall section 36 is provided parallel to the legs 12, 13 and preferably close to them. This expediently extends in the length from the cross slide 20 to the opposite coil flange 5 and in the height from the inside of the bottom part 1 to the inside of the lid top 33.3.
  • the wall sections 36 are advantageously formed on the base part or on the cover part 33. Through these wall sections 36 switching chambers 37 are formed in the relay for the contact systems, which are practically completely separated from the rest of the relay structure.
  • connections 7; 7.1; 7.2 and 7.3 are advantageously provided in a so-called dual-in-line arrangement and in particular additionally arranged in a grid dimension.
  • these connections can be designed for the so-called OMD technology, ie in such a way that the relay can be mounted and soldered on the surface of a circuit board.
  • they can be angled inwards, as shown in dashed lines in FIG. 1, or they can similar to or according to Figures 4 to 7 angled outwards. 4, in particular, they can be angled directly and provided with an upstanding protrusion 35, or they can, in particular, according to FIG. 5, they can be angled directly and at the end Z-shaped, or they can only be angled according to FIGS. 6 and 7 be angled outwards after a section that remains straight.
  • At least the outside 1.1 of the base part 1 can be trough-shaped in a view in the direction of the longitudinal axis L of the coil, that is to say in cross section to it.
  • the connections 7; 7.1; 7.2 and 7.3 out of the bottom part 1 and the edge 33.1 of the cover part 33 projects at least slightly beyond these edge regions, so that these edge regions 1.3 can be cast with a sealing compound 34.
  • the relay can be degassed and / or filled with a filling gas and the relay can then be closed by filling a drop of a sealing compound into the depression 1.4.
