Definitions

  • the present invention relates to a small relay with a spring bracket for holding the magnetic coil and the spring contact set, the bottom wall of which is provided on the outside with plug or solder connections.
  • Relays used to carry out switching functions are usually installed upright, with the spring contact set arranged parallel to the solenoid.
  • the pivotable armature arranged in the area of one end of the magnet coil is consequently provided in the area of its articulation point with an angled extension which acts on the movable contacts of the spring contact set via corresponding insulating pieces.
  • a small relay is thus already known, in which, in order to reduce the overall height of the relay as much as possible, installation in corresponding cards with a small mutual spacing is possible, in which case the spring contact set is arranged above the solenoid arranged in a horizontal position.
  • the individual spring contacts of the spring contact set must be angled, and insulation problems also occur because the line connections of the solenoid cross with the line connections of the spring contact set.
  • this is achieved in that the longitudinal axis of the magnet coil is arranged perpendicular to the longitudinal axis of the spring contact set.
  • the small relay according to the invention has a spring bracket 1 at the bottom, onto which a hood 2 made of a transparent plastic material is sealed, which seals the small relay from the outside.
  • the spring bracket 1 serves as a support for a magnetic coil 3, which is composed of a cylindrical core 4, a coil former 5 made of plastic material, an electrical winding 6, a yoke 7 leading around the outside of the coil former 5 and the winding 6, and a pivotable armature 8 is.
  • the longitudinal axis 9 of the cylindrical core 4 of the magnet coil 3 runs parallel to the base plate 10 of the spring bracket 1.
  • this groove 12 protrudes from the outside of a nose 13, which nose 13 is offset in relation to the end face of the yoke 7 in such a way that under the elastic properties of the block-shaped extension 11 of the coil body 5, the pivotable armature 8 in the idle state in the position lifted from the end face of the cylindrical core 4 is pivoted.
  • the pivotable armature which is arranged vertically with respect to the base plate 10 of the spring bracket 1, has at its upper, free end a rectangular opening 14, into which an extension 15 of a flat actuating web 16 projects.
  • This actuating web 16 leads above the magnetic coil 3 to the other side of the small relay, at which point the spring contact set 17 is arranged.
  • This spring contact set 17, taking into account FIG. 2, consists of two changeover contact sets 18, 19, which can be activated together with the aid of the actuating web 16.
  • the actuating web 16 has two arranged on the opposite side of the extension 15 Web sections 20,21, which are provided with corresponding extensions 22,23, which protrude through rectangular openings 24,25 of the changeover springs 26,27 of the two changeover contact sets 18,19.
  • the two changeover springs 26, 27 and the normally closed contact carrier 28, 29 and make contact carrier 30, 31 are provided in the upper region with contact pieces 32, two of which can be brought into contact depending on the pivoting position of the changeover springs 26, 27, thereby optionally one electrical connection of the changeover springs 26, 27 to the normally closed contact carriers 28, 29 or the working contact carrier 30, 31 can be established.
  • the spring contact sets formed by the elements 26-31 are provided at the bottom with plug or solder connections 33 to 35, these plug and solder connections 33 to 35 being mechanically fixed in position within the spring bracket 1. This positioning of the plug or solder connections 33 to 35 within the spring bracket 1 takes place in that these plug and solder connections 33 to 35 are extrusion-coated during the manufacturing process of the spring bracket 1.
  • the spring contact sets 17 consisting of the individual spring contacts 26 to 31 are arranged according to the present invention such that the longitudinal axis of the spring contact set 17 extends perpendicular to the longitudinal axis 9 of the cylindrical core 4 of the magnet coil 3.
  • the individual spring contacts 26 to 31 can thus be carried out essentially vertically through the base plate 10, but the plug or solder connections 34 of the changeover springs 26, 27 are guided through the base plate 10 of the spring bracket 1 while forming a Z-shaped configuration, while the two plug or solder connections 33 on the side of Magnetic coil 3 to rest resting contact carrier 28, 29 are passed according to the illustration using a diagonal offset, whereby it can be achieved that while maintaining a small distance between the individual contact springs 26-31 the associated plug or solder connections 33 to 35 on the Outside of the spring bracket 1 have a relatively high, mutual distance, so that there are sufficiently large creepage distances between the individual plug or solder connections 33 to 35 in view of the required insulation properties.
  • an intermediate wall 36 is provided according to FIG. 2, which is formed by a corresponding molding within the spring bracket 1. 4, this intermediate wall 36 formed by the spring bracket 1 extends into the region of the inner wall of the hood 2, as a result of which a certain guidance of the actuating web 16 provided with the two web sections 20, 21 can also be achieved.
  • the spring bracket 1 is additionally provided with two upwardly projecting lugs 37, 38, which ensure good positioning of the rest or working contact carriers 28 to 31.
  • the block-shaped extension 11 provided on the coil former 5 additionally serves to hold two plug or solder connections 39, 40, to which the ends of the electrical winding 6 are fastened, for example by soldering.
  • plug or solder connections 39, 40 are angular in design, the outer ends being formed by corresponding recesses within the base plate 10 of the Protruding spring bracket 1 outwards.
  • the small relay according to the invention is additionally provided with a plug or solder connection 41 which is arranged along the center plane of the relay and which serves as an earth connection for the relay in question.
  • a plug or solder connection 41 which is arranged along the center plane of the relay and which serves as an earth connection for the relay in question.
  • the still required anchor spring of the pivotable armature 8 is formed with the aid of the nose 13 of the block-shaped extension 11 protruding into the groove 12, this spring can also be formed by a spring leg 44 formed by the insulating material of the extension 11 (FIG. 8, 9) can be achieved, which presses on the outer surface of an anchor which is angled in the region of the articulation point.
  • a spring tab made of plastic material
  • an angle piece 43 made of metal can also be provided, which is inserted into a corresponding slot in the block-shaped extension made of insulating material.
  • the inner walls of the hood 2 provided in the area of the actuating web 16 and the surfaces of the spring bracket 1 below the actuating web 16 can also be provided with projecting projections 42, which are arranged at a distance from the actuating web 16, and the like Actuating web 16 give a certain guidance and prevent the operating web from vibrating if vibrations are exerted on the small relay from the outside.
  • a contact bridge and / or a permanent magnet are arranged on the actuating web, these elements, in conjunction with fixed contact pieces or a reed switch, causing the closing or opening of one or more circuits can.
  • the advantage of the proposed solution according to the invention is that the control and switching circuits do not cross each other and that a small mounting area is achieved with a small overall height on the circuit board.
  • the coil body serves as a holding element for the armature and the coil body is a supporting element for the magnet frame, the required miniaturization can be achieved without the magnetic force having to be reduced, as is the case with small relays of comparable size.
  • the known anchor retaining spring is omitted, so that there is also a simple plug-in assembly for the anchor.
  • the armature with respect to the coil lies exactly opposite the contact springs, the greatest possible air and creepage distances between the magnet and contact system of about 8 to 14 mm result, so that such a relay meets the highest safety requirements, e.g. corresponds to that of underground mining.
