Definitions

  • the invention relates to a flat relay, in particular a miniature flat relay, according to the preamble of claim 1.
  • connection elements for the coil and the connection elements for the contact arrangement are spaced far apart and arranged over the lower housing part.
  • connection elements lie one behind the other in a line, i.e. the connection elements are arranged in the so-called in-line or dual-in-line technology.
  • a high dielectric strength of, for example, at least 1500 V between the adjacent coil and contact spring connecting elements should be ensured without additional assembly effort.
  • the lower housing part 1 made of insulating material has a bottom 2, on which the first chamber 5 is formed by two vertically standing chamber walls 3 and 4 which are offset inwards parallel to the longitudinal edges of the bottom.
  • the magnet system formed from the coil former 6, the coil 7, the yoke 8, the core 9, and the armature 10 is inserted into this chamber 5.
  • the yoke 8 consists of a U-shaped, upright soft iron strip, in the base 11 of which the core 9 is fastened.
  • the core 9 protrudes a little on the end face of the coil former 6 facing away from the base 11.
  • the armature 10 consists of two rods 13 and 14 made of ferromagnetic material, which are inserted at a distance from one another in the actuating member 12 made of insulating material, and a permanent magnet 15 connected to them.
  • the actuating member 12 is displaceably arranged at right angles to the longitudinal axis of the magnet system.
  • the rod sections 13, 14 should protrude slightly beyond the outer limit of the actuating slide 12.
  • the spacing 16 of the rod sections 13, 14 from one another is greater than the cross section 18 of the core 9 by the double air gap 17. into which the legs 22, 23 of the yoke 8 are inserted.
  • connection element 35 or 36 is fastened in the side flange sections 24, 25, a connection element 35 or 36 is fastened.
  • the flange portions 24, 25 laterally have such an extent that they protrude beyond the adjacent chamber walls 3, 4.
  • a housing hood 26 can be plugged onto the lower housing part 1.
  • the edge of the housing hood 26 preferably projects beyond the underside of the base 2, so that openings and gaps on the underside of the base 2 can be easily sealed by filling with potting compound.
  • Two opposite lateral outer walls 27, 28 of the housing hood 26 each form a second chamber 29 and 30 with the chamber walls 3 and 4, respectively.
  • the contact arrangements 31 and 32 are arranged in these chambers 29, 30.
  • the flange sections 24, 25 protrude into these chambers 29, 30, and the connection elements 35 and 36 projecting below the flange sections 24, 25 project through an opening 37 in the bottom 2 of the lower housing part 1 to the outside.
  • connection elements 35, 36 and the connection elements 41, 42, 43 of the contact arrangements 31, 32 inserted through openings 38, 39, 40 in the base 2 lie in a line, so that in-line or dual-in-line connections are formed .
  • the partition walls 44 can also be used as a single part with sufficiently large dimensions of the flat relay, or they can be integrally formed on the lower housing part 1.
  • partitions 44 allow the parts of the connecting elements 35 and 41 or 36 and 41 projecting below to be spaced apart, e.g. to be attached in a grid dimension of 2.5 mm, but to make the distance significantly shorter at the top, i.e. inside the housing.
  • the connecting element 41 is provided on the inside with a flag-like tab 47, which is oriented in the direction of the connecting element 35, 36 or towards the partition 44.
  • the partition 44 By means of the partition 44, the distances between the connection elements 35 and 41 or 36 and 41 can be reduced, for example, to 1 mm and below without the dielectric strength of e.g. Falls below 1500 to 4000 V. Due to the larger contact surface of the tab 47 of the connecting element 41 directed in the direction of the dividing wall 44, the length of the contact spring 49 fastened to it and carrying the movable contacts 48 can be greater.
  • the free end 50 of the contact spring 49 is inserted with little or no play in the slot 51 of the actuator 12.
  • the actuator 12 is slidably mounted. It is supported on the free ends 50 of the contact spring 49.
  • at least two knobs 54 are formed on the upper side 52 and on the lower side 53 of the actuating member 12. The one on the bottom 53 located knobs 54 are not visible in the drawing. Their position is indicated by arrows 55.
  • the contact spring 49 is designed as a leaf spring, which expediently has at its end 50 a double tongue with one contact 48 each and is arranged parallel or approximately parallel to the chamber wall 3 or 4.
