Definitions

  • My invention has for its object an iron clad electromagnetic relay having an outer cylinder and a central core of magnetic mate- ⁇ r1a1 carryin at its ends magnetic covers closlI ing the cyhnder.
  • my invenl0 posed a contact spring secured through one end to one core element and carrying in front of the nonmagnetic body the armature adapted to be attracted by the core in a kdirection substantially perpendicular tothe axis ofthe latter.
  • Fig. 1 is a cross-section of the devic through the axis thereof.
  • Fig. 2 is a cross-section perpendicular to the axis showing the connection between the coil and the terminals.
  • Fig. 3 shows diagrammatically the distribution of the lines of force.
  • the electromagnet comprises two alined bars of suitable magnetic metal such as soft iron 1 and 2 connected through a sufficiently thick plate 2, of nonmagnetic material such as copper or brass.
  • the bar 2 engages with some friction the central aperture of a disc 4 of same magnetic metal, part of the aperture remaining free so as to allow the contact-bearing spring 7 of the relay to pass.
  • the disc 4 is provided with a flange 8 inside whichL a cylinder 9 also of soft iron or the like is engaged with slight friction so as to form the casing of the relay.
  • a cylinder 9 also of soft iron or the like is engaged with slight friction so as to form the casing of the relay.
  • the cylinder is providedwith a circular groove carrying a second disc 11 of soft steel or the like provided with a central aperture.
  • the soft steel bar l ends with ashoulder 12 and a part of reduced diameter 13 passing through the said aperture in the disc 11; its end is threaded for receiving the assembling nut 14.
  • the exciting coil 15 is Wound over a copper or brass tube 16 and is bounded by insulating flanges 10.
  • the ends of the wire forming this coil are connected with plugs 17 (F ig. 2) passing through the disc 4 from which they are insulated by sleeves such as 18.
  • the plugs are fitted with friction inside metal sleeves carried by the insulating support 19 and provided at their ends with terminals or else with wires to which are Welded the ends of the outer leads.
  • the plate 19 is geld against the disc 4 by a shoulder 22 on the
  • the movable armature 23 is secured to the springr 7 of nonmagnetic material such as bronze or brass. This spring'is secured to the bar 1 through one end, the other end carrying a contact part 24 adapted to open or to close the circuit controlled by the relay.
  • the movable armature 23 is disposed in front of the connecting plate 3.
  • My relay is capable of many applications. It is in particular very'useful in systems for protection against fire andtheft.
  • the core, the outer discs and the cylindric casing are of soft iron.
  • any magnetic metal may be used and it is possible by using a suitable material to make the properties of the relay vary to a considerable degree.
  • I mayreplace the soft iron by metal or alloys which are magnetically very permeable such as the so-called permalloy alloy or certain very pure nickel-iron alloys.
  • the same parts may be advantageously made of a similar alloy having a smaller remanent power.
  • Vhat I claim is:
  • An electromagnetic relay comprising a magnet body constituted by a central core of two alined elements separated by a gap, two discs fitted over the outer ends of said elements and a cylindrical part fitted between the peripheries ofthe discs, a non-mag netic part separating the two core elements, a spring disposed parallel to and adjacent the core7 a coil wound over the core, and passing over the spring, means for securingr one end of the spring, a contact controlled by the spring and an armature carried by the spring in front of the non-magnetic part separating the two core elements.
