Definitions

  • the present invention relates to a built-up polarized relay and more particularly to a relay for calculating machines.
  • the primary object of the invention is the provision of relays a great number of which may be accommodated in a limited space.
  • Another object is the provision of a relay capable of easy assembly and wiring and permitting a general lay-out of the relay installation which is easy to inspect.
  • the use of the relay according to the invention is, of course, in no way restricted to calculating machines, and the relay can be used to advantage also for telephone exchanges and the like.
  • the present invention generally aims at overcoming the aforesaid and other shortcomings of known built-up relays.
  • the relay includes an insulating body consisting of two identical parts, each having substantially the shape of the letter H.
  • the web portion of each H-type body constitutes one half of a coil former on which the exciting coil of the relay iswound.
  • Recesses in the iiange portions of the body parts accommodate polarizing magnetic units.
  • Other recesses in the flange portions are provided for tongueshaped relay armatures, and the contacts cooperating with the armatures are also inserted in the anges.
  • the arrangement is such that the tongue-like armatures are located in the plane of contact between the two parts of which the relay body is composed.
  • FIG. 1 is an axonometric view of a four-contact relay of the invention.
  • FIGS. 2a and 2b show the two body parts of the relay of FIG. l in a corresponding exploded view.
  • FIG. 3 is an axonometric view of the magnetic and electrical components of the relay of FIG. 1.
  • FIG. 5 shows a terminal arrangement for the relay of FIG. 1.
  • the insulating body of the relay is preferably made by moulding from a synthetic material, and consists of two identical parts lil. Each part has the shape of the letter H with two anges 11, connected by a web 12..
  • the flanges 11 and the web 12 have respective raised rims 112 and 121.
  • a cavity is formed between the two Webs 12 and serves to accommodate a core Z1 of an electromagnet as will be described hereinafter.
  • Several recesses are arranged in the flanges 11.
  • each ange 11 Adjacent the ends of each ange 11, there are recesses 11i) which receive a magnetic polarizing unit 30 including pole pieces and polarizing magnets.
  • Longitudinal recesses 111 are intendedv to accommodate tongueshaped armatures 22 of the electromagnet and pole pieces 210 of the core 21.
  • Recesses 113 in the external body faces parallel to the contact plane of the two parts accommodate terminals for the relay contacts, and finally there are recesses 114 at the longitudinal sides of each flange 11 providing space for the conductors connecting several superposed or juxtaposed relays.
  • the opposite faces 115 of the flanges 11 of each body part 10 constitute the end plates of a former on which an exciting coil 20 is wound about the core 21. Due to the smoothness of the faces 115, the exciting coil can be wound without diiiiculty, and needs no special insulation because of the insulating qualities of the material from which the two body members 10 are moulded.
  • Each part 1t) has at its outer side a flat seating face 116, which serves as an abutment or support for an adjacent relay.
  • a multitude of relays may be assembled by placing them upon one another without any special carrier members.
  • the relative position of two assembled body parts 11i as well as the relative position of several superposed relays are secured by connecting members such as pins which are inserted into aligned apertures 118 in the body parts 10.
  • the main magnetic circuit of the relay includes the core 21 lwhich may consist of two identical halves on both ends of which pairs of laterally oppositely projecting tongue-shaped armatures 22 are mounted in respective insulating blocks 24.
  • the free ends of the armatures 22 are movably arranged between pole pieces 31 of permanent polarizing magnets 32.
  • the tongue-shaped armatures 22 constitute contact springs which make alternate contact with oppositely arranged contact screws 23.
  • the armatures 22 are provided with connecting eyelets 220.
  • Each magnetic polarizing unit 30 comprises two pole pieces 31, having each the shape of a at letter U, Ibetween which permanent magnets 32 are inserted with equal poles facing in the same direction.
  • the magnets 32 are secured in grooves 310 provided in the pole pieces 31.
  • the core 21 may consist of two parts placed upon one another and held together in the cavity between the webs 12 when the body parts ⁇ 10 are assembled.
  • a core having two armatures is substituted for the core 21 having four armatures 22.
  • the two armatures of course cooperate with a single magnetic polarizing unit 30.
  • the other unit 3l) is in this case dispensed ⁇ with entirely.
  • a polarized relay comprising two substantially identical lbody parts of insulating material, each body part having two flange portions and a web portion integrally connecting said fiange portions; fastening means for securing said body parts to each other with the respective flange and web portions of one body part superimposed on the corresponding portions of the other body part, said parts when secured to each other constituting the body of said relay and substantially defining the external dimensions thereof, said web portions jointly defining a coil former having an internal cavity; a magnetizable core in said cavity, said body being formed with a first recess extending in at least one of said iange portions and com municating with said cavity, and with a second recess spaced from said cavity and communicating with said first recess; a plurality of windings on said coil former for magnetizing said core and energizing a magnetic field thereof; polarizing magnet means mounted in said second recess, said magnet means having spaced pole piece means; an elongated armature member mounted in said rst
