Definitions
- This invention relates to electromagnetic relays.
- Another important object of the invention is to provide a novel and advantageous electromagnetic relay.
- a further object of the invention is to provide a novel and advantageous electromagnet-andarmature device.
- This invention includes an electromagnetic relay comprising a substantially flat armature pivoted near its center and arranged so that the operating force and contact load are applied on opposite sides of the pivot, and so that the gravitational moments of the masses of the moving vparts are substantially balanced about the pivot.
- Fig. 1 is a view in side elevation
- Fig. 2 is a left-hand end view
- Fig. 3 is a right-hand end view
- Fig. 4 is a top-plan view with the contactspring pile-up removed to expose the armature
- Fig. 5 is a view in longitudinal central section.
- the usual relay winding II mounted upon a soft-iron core I2 of which the forward projecting end is turned up and then back to form a pole-piece I3 with its flat uppermost surface constituting the pole-face.
- a yoke I4 Tightly fitting over, and preferably welded to, the rearward projecting end of the core I2 is a yoke I4 extending upwardly and forwardly along the top of the winding II to within a short distance of the pole-piece I3.
- the armature which will be more particularly described, is shown at I5 bridging the gap be- "tween yoke I4 and pole-piece I3: the contactspring pile-up is shown at I6.
- the armature I5 is almost but not quite flat when viewed edgewise and that it lies in a plane substantially parallel with those of the contact-springs of the pile-up I6.
- a D-shaped opening is cut away in the rearward half, leaving a frame-like tail I1 that normally rests upon the supporting stop 22, for engagement with the lifting pins I8 on the pile-up I6. This tail is bent slightly upwards with respect to the plane of the remainder of the armature.
- the most rearward part lies between the flanks of the D-shaped tail-frame and terminates in a knife edge I9 which lies slightly below the level of the tail and which therefore is able to constitute the pivot for the armature as it rests upon the upper surface of the yoke I4 with its solid forward half overlying the pole-face on the piece I3.
- Energization of the coil II causes the forward end of the armature I5 to be attracted downwardly to the pole-piece I3, the armature turning about the edge I9 so that the tail I1 rises from the stop 22 and through the intermediary of the lifting pins I8 causes operation of the contacts of the pile-up I6.
- the operating force and the contact load are applied on opposite sides of the pivot.
- the armature pivots on its edge across almost the full width of the relay, making an iron to iron contact with the yoke which it overlaps to provide a low reluctance hinge joint.
- the armature is permanently located in its correct position by means of light leaf springs 20.
- these springs formed integral with a single cross piece and. extending parallel with the longitudinal axis of.' the armature, that is at right angles to the pivotal axis I9. They thus underly the iianks: of the D-shaped tail-frame of the armature. At; their forward ends they are welded to the underside of the armature, and at their rearward ends they are welded to the top surface of the yoke I4.
- Beryllium-copper is a suitable material for the springs.
- the dimensions of the armature locating springs are chosen so that the forces exerted by them on the armature over the full range of armature movement are small relative to those due to the contact springs in the pileup IE.
- the springs are not by themselves strong enough to perform the usual retractile function, and reliance must be placed primarily upon the resilience of the contact-springs, in the usual manner.
- the additional springs 2D may be biased so as to ensure that the knife edge on the armature seats always on the yoke, thus avoiding hammeringvupon the knife edge.
- the contact unit is xed to the magnet sysl tem by a single screw 2! passing througlx"they moulding,A acting as support of the Contact spring pileup i6, -into-thelryokefandiis located? atfthfe. forward endby twostepsv-in/ the mould-ing which tf'foverthe edge of the pole; face.
- thepile-'up constitutes an ⁇ independent funt, ar'1d ⁇ that,-in particular, its adjustment'can be carried out' before assembly with the remainderof the!V relay.
- the moulding of ⁇ rv the contactspring Asindicated in Figs. l, 2 and 3, the moulding of ⁇ rv the contactspring.
- pile-up i6 has' a,-fvvidel forward portion above the ,pole-piece I3fanda narrower portion extending'rearward.n lyl between theV contact-springs which are clamped at the sides of said wide portion.r
