Definitions

  • the present invention relates to relays, and more particularly to relays of the electro-magnetic type having a movable armature together with switch means connected in an electrical circuit to be controlled incident to the movement of the armature.
  • the switch means for controlling an electrical circuit incident to the movement of the armature usually necessitates the use of a special mounting bracket associated with the field piece.
  • Such construction results in a rather awkward unitary device of substantial size limiting its field of use, and which is relatively expensive to manufacture.
  • One of the objects c'.' the present invention is to provide an improved form of electro-magnetic relay of the character indicated which is of relatively compact form, durable, positive in operation and capable of being manufactured for substantially less than equivalent devices heretofore marketed.
  • Another object is to provide an improved form of electro-magnetic relay of the type indicated which is characterized. by the provision of a panel of insulating material rigidly attached to the upper end of the core in a manner to.con stitute a head for the coil, said panel also serving to provide a convenient mounting surface for the switchingmeans to be actuated lincident to the movement of the armature.
  • a further object is to provide an improved relay device of the character indicated wherein a panel of insulating material is rigidly attached to the upper end of the core in a manner to constitute a head for the coil and also serve as a convenient mounting for novel switch means of relatively simple form and which is capable of being easily assembled.
  • Figure 1 is a top plan view of a relay device cmbodying the present invention.
  • Figure 2 is a view part in section and part in elevation, taken substantially as indicated at line 2 2 of Figure 1.
  • Figure 4 is a top plan view of a relay device embodying a modified form of the present invention.
  • Figure 5 is a side elevational view of the relay shown in Figure d.
  • Figure 6 is a view part in section and part in elevation, taken substantially as indicated at line 6--6 of Figure el.
  • the electro-magnetic relay illustrated in Figures 1 to 3 of the drawing includes a stamped, metal tield piece l0 of generally U-shaped formation, ⁇ one leg of which, as indicated at ii, continues into an extension l2, bent inwardly above the field piece to serve as a stop for limiting the movement of the armature away from the core, as hereinafter described.
  • the upper portion of the leg Il of the field piece is reduced and shouldered as indicated at I4 in Figure 3, to provide a seat or hinge mounting for an armature I6.
  • Said armature is slotted and snugly fitted on said reduced portion of the leg li and includes a. rearwardly extending portion l1 formed to provide an anchorage for one end of a coil spring I8, the lower end of which spring being attached to a lug 20 struck out of the lower portion of the upright leg Il of the field piece.
  • the extension I2 of the leg Il is tapered as seen in the drawing, and the extreme end portion thereof is bent downwardly to a position to be encountered by the armature I6 at its uppermost position of adjustment, as seen in Figure 2, to which position it is yieldingly urged by the coil spring I8.
  • a coil- 23 having a core 24, the upper end of which extends a substantial distance above the end of the coil 23.
  • a panel 2B of insulating material mounted on said extended end of the core.
  • the panel is rigidly secured in position on the end of the coil by staking of the end of the core at a plurality of circumferentially spaced apart points, as indicated at 21.
  • the panel 25 preferably includes a notched portion 26 of U-shaped form to embrace the upright leg Il of the field piece for assisting in maintaining the panel in fixed position.
  • 'Ihe panel of insulating material in the construction illustrated is preferably of such dimensions as to provide portions 26 projecting later- Figure 3 is a View part in section and part in 55 ally beyond opposite sides of the armature i6.
  • portions of the panel 2t provide convenient mountings for a dual set of switch means which, as illustrated, are similarly mounted on each of said panel portions 26".
  • means each comprise a conductor finger 29 riveted to the upper side of said portion of the panel and a conductor finger 3B riveted to the underside of said portion of the panel iii-offset relation to nger 29, as may be seen in Figure 2.
  • Said conductor fingers are'dimensioned to extend forwardly beyond the edge of the panel and are provided with cooperating contact buttons 23 and 3138, respectively, and the other ends cf said conductor fingers are formed with terminals 29h for connection to conduccircuits to be controlled.
  • iingers 3e include an exend, projecting a subtor wires of electrical
  • the conductor fingers 30 are formed of resilient material and are normally biased in a direction with respect to correspon 'ng conductor fingers 29 so as to dispose the contact buttons 29a and 30e in engagement with each other. It will therefore be apparent that when the coil 23 is deenergized the armature i6, under influence of spring I8, is caused to assume a position as seen in full lines in Figure 2 of the drawing with the 4contact buttons 29a and 3
  • switch means herein shown and described is shown in normally closed position when the armature is deenergized, manifestly said switch means may be modified so as to function inl a manner opposite to that shown and described.

  • Said conductorflngers are provided with extensions 31b and 38b respectively for connection to conductor wires in an electrical circuit to be controlled.
  • Said bent portions 31 and 38 of the conductor fingers as may be seen in Figure 5' of the drawing, are bent downwardly in parallel spaced apart relation at an angle to the plane of the armature in either its attracted or released position.
  • the ends of said angular portions 31a and 388L are provided with spaced apart contact buttons 31 and 38 respectively.
  • Mounted on the armature i6@ in alignment with the contact buttons 31 and 38 is a conductor iinger 39 of flexible material having a portion extending forwardly beyond the free end of the armature and bent downwardly at an angle to extend between the contact buttons 31, 38C.

  • the conductor finger 39 of flexible material and disposing the bent portions 31a and 38a of the conductor fingers 31 and 38 respectively at an angle as above described is to permit double contact button 39a to engage the contact buttons 31 or 38 in a wiping manner for assisting in maintaining the contacts clean and assuring posiment with each other and extending in front of tive completion of electrical circuit through said contacts.
