  • ElectricalConsiderations The electrical characteristics of the disclosed relay will be understood from a studyof FIG. 2, which is a top view of the relay looking into the relay from a level corresponding to the junction of the relay cover 10 and the relay base 12 asindicated in FIG. I.
  • relay base 12 comprise a roughly open box configuration
  • relay elementsythese relay elements now being identified with lower case letters for a reason that will become apparent later i.e., 15a, 15b, 16a, 16b,- 17a, 17b, etc. these relay elements protruding both" inwardly and outwardly of the relay base side walls 3 straight in FIG. 2,' and projects straight through the wall 25 of relay base 12.
  • straight element a comprises an outer lead end that is to be connected to the previously mentioned printed circuit board so that the outer lead end extends in a generally downward direction.
  • Str aight element 15a also comprises a transition portion that provides a transition from the downwardly extending lead end across the top of side wall of the relay base 12', the transitionportion of the straight element extending in a generally horizontal direction.
  • the straight element 15a also comprises an interior portion that terminates in a contact surface 27 that may be the end of the horizontal transistion pornal is appliedvto contact surface 27 of straight element 15a, the electrical signal will'be available'at the outer lead end or output terminals, that is electrically connected to the printed circuit board 20.
  • The'Switching Element I Attention is again directed to FIG. 2, this time to one of the lower relayelements 16b; this relay element is to be calledthe switching element because (in a manner to be discussed soon) a portion of relay element 16b acts as a switch.
  • the switching element 16b comprises an outer lead end that is to be connected to the previously mentioned printed circuit board 20; so that the outer lead extends in a generally downward direction.
  • Switching element 16b also comprises a transistion portion that provides a transistion from the downwardly extending lead end across the top of side wall 25 of the relay base 12; this transistion portion of the switching element 16b extending in a generally horizontal direction within the relay base 12.
  • the switching element 16b also comprises an interior portion that terminates in a switch arm b.
  • the configuration of the switching element 16b resembles a capital L" lying on its side, and having its short arm bent into an horizontal plane see 16b of FIG. 4; this switching element configuration being designated as a bent L" that will be furtherdiscussed later. Suffice it to say, the now horizontal portion of the bent L configuration forms-the transistion portion of the switching element 16b, while the base of the bent L configuration forms the switch arm 30b.
  • switching element 16b of FIG. 2 has a switch arm 30b that acts as though its proximal end were pivoted" at switching element 16b, while its distal outer end moves as indicated by double ended along its switch arm 30b to the contact surface 27 of the straight element 15a. In this way, an input electrical signal applied to the input terminal switching element 4 16b may be made available at the output terminal lead endof straight element 15a.
  • switch arm 30b maybe pivoted slightly counterclockwise, as indicated by the double ended arrow 31; so that the distal end of the switch arm 30b no longer contacts the contact surface 27. At that time, the input electrical signal applied at switching element 16b will'no longer be available at the output terminal lead-end of straight element 15a.
  • switching element 16b and its switch arm 30b areformed in such a manner that its inherent resiliency and its bias due to the forming processes cause the switch arm 30b to normally be with the contact surface 27 of straight element 15a.
  • the technical designation for this electrical state is that the circuit is normally comp1ete;. i.e., the switch at straight element 15a'is normally closed; and the straight element 1.5a is'thus a normally closed terminal of a switching arrangement.
  • the offset element 18b comprises an outer lead end that is to be connected to the above mentioned printed circuit "board 20; so that the outer lead end extends in a generally downward direction.
  • Offset element 18b also comprises a transistion portion that provides a transistion from the downwardly extending portion of the offset element 18b extending in a generally horizontal direction.
  • the offset element 18b also comprises an interior offsetting elbow that terminates in a contact surface 34 that may be the horizontal end of the elbow, but is preferably a contacting surface that extends in a generally downward direction.
  • the Switching Operation It will be noted that, for the relay illustrated in FIG. 2,.the switch arm 30b does not normally contact the contact surface 34.0f the offset element 18b. Therefore, an input electrical signal applied to the input terminal of switching element 16b would not be transferred to contact surface 34; and would not be present at the output terminal lead end of offset element 18b.
  • the offset element 18b is thus a normally open terminal of the switching arrangement.
  • switch arm 3011 may be moved appreciably counterclockwise indicated by the double ended arrow 31; so that the distal end of switch arm 30b no longer contacts the contact surface 27, but rather contacts the contact surface 34. At that time, an input electrical signal applied to the input terminal switch element 16b would be applied to the contactsurface 34 of the offset element 18b; and will therefore be present at the output terminal lead end of the offset element 18b.
  • the relay may be used to switch an input signal that is present at switching element 16b to either the straight element 15a or the offset element 18b; and in a manner to be discussed later, either condition of the'relay may be held for any desired length of time.
  • the relay base 12 actually contains two sets of relay elements 15a, 16, 17a, 18a; and 15b, 16b, 17b, and 1812. These two sets of relay elements are illustrated as being identical, but as being reversed longitudinally with respect I to each other; and as being each other.
  • 15a and 15b are both straight elements; 16a and 16b are both switching elements; and 18a and 18b are both offset elements (realy elements 17a and 1712 will be discussed later). Therefore, the above discussed switching operations may be performed by each of the two corresponding, but individual, switching arrangements (16b, 15a, 18b; 16a, 15b, 18a). in this way, the disclosed relay may operate as two single-pole double-throw relay switching arrangements; or may operate as a double-pole double-throw switching arrangement each switching arrangement handling its own individual electrical signal.
  • F l6. 2 illustrates that the contact surfaces, such as 27 and 34, are con vexly curved; but this curvature is not essential.
  • the main requirement is that all contact surfaces must provide good electrical conductivity; this in opposition,.i.e., facing result being most readily obtained by suitably plating the contact surfaces gold or silver plating being preferable in order to provide long lived contact surfaces.
  • relay elements l5, l6, l7, and 18 are illustrated as being flared slightly outwardly; this flaring aiding in snapping the relay '10 into place on the printed circuit board, and also aiding in the holding of the relay in place prior to the soldering operation that affixes the relay mechanically to the printed circuit board.
  • Relay Operation It has thus far been explained how the disclosed relay may act as a switch of a desired type, by selecting a suitable number of relay elements, and by suitably positioning these relay elements. As indicated above, it is one of the desirable functions of a relay to be operated remotely, as by an electrical signal; and an explanation of how the disclosed relay achieves this remote control function will be understood from a further study of FIG. 2.
  • a switching arrangement such as relay 10 of FIG. 2 has one or more normally closed contacts and one or more normally open contacts.
  • the normally closed contacts are the straight elements a and 15b; and the normally open contacts are the offset elements 18a and 18b so that input signals applied to switching elements 16a and 16b would normally appear at the normally closed straight elements 15a'and 15b.
  • This result is obtained by the curving and the biassing of the switch arms 30a and 30b so that they normally contact the straight elements 15a and 15b,- but other normal states can be achieved by other curvature and biassing of the switch arms.
  • magnetic source (to be discussed later) causes magnetic flux to flowout of the magnetic source; and through two pole pieces 40 and 41 of FIG. 2, as indicated by the arrows. These pole pieces 40 and 41 now serve as locations that produce localized magnetic fields.
  • the main reason for offsetting the offset elements 18a and 18b is to provide a location for the magnetic pole pieces 41 and 42, so that the .pole pieces are located close to the distal ends of the switch arms'30a end 30b. This extreme end location of the magnetic pole pieces providesoptimal movement of the switch arms 30a and 30b.
  • the magnetic flux acts in'such a manner as to reduce the overall reluctance of the loop; and, in the present case, it reduces the reluctance by attracting the movable distal ends of the switch arms 30a and 30b closer to the fixedly positioned magnetic pole pieces 40 tion for the switch arms disappears; and the inherent resiliency and bias of the switch arms cause them to return to their normal illustrated state where they are and cobalt-vanadium-iron being typical of such special alloys.
  • the switch arms 30a and 30b are therefore preferably made of a material of this type; and, as indicated above, are also preferably plated with gold or silver or clad" with suitable layers to enhance their electrical characteristics at the area where they contact the contact surfaces.
  • New alloys such as nyborium give premise of possessing mechanical, magnetic, and eleccladding.
  • the Magnetic Yoke The above discussion has treated the two switching arrangement as though they were separate from each other;.but they are actually interconnected for a very specific reason.
  • magnetic flux would flow in the direction of the arrow to the switch arm 305; would flow along switch arm 30b to the switching element l6b, would then flow along a magnetic yoke 42 to the other switching element 16a; and would then flow along switch arms30a to magnetic pole piece 41.
  • magnetic yoke 42 is a vital part of the series connected magnetic circuit, and should also be comprised of amagnetic material.
  • the magnetic yoke 42 is also electrically connected directly across switching elements 16a and 16b; and may provide an undesired electrical interconnection, or a short. Therefore, the magnetic yoke 42 must be, per se, either an electrical insulator or must be electrically insulated from one or both of the switching elements 16a and 16b.
  • it may be an air gap; alternatively it may comprise have the above discussed electrically insulating film on their inner surfaces (or on all surfaces); and the film coated inner surfaces are adhered, clamped or otherwise afiixed to the vertical surface of respective switching elements 16a and 16b.
  • the magnetic yoke 42 completes the magnetic loop; but electrically separates the switching elements 16a and 16b.
  • the disclosed relay provides practically simultaneous switching, as may be understood from the following considerations. Assume that one of the switch arms, say 30b for example, tends to move faster; and to thus complete its circuit somewhat earlier than the other switch arm 30a. As the distal end of switch arm 30b approaches its respective contact surface 34, the decreased length of its air gap increases the amount of magnetic flux, and this increased magnetic flux acts on the other magnetic pole piece 41 to provide a stronger magnetic field that accelerates the movement of its associated switch arm 30a. In this way, the disclosed series type magnetic arrangement tend to equalize the movement of the two switch arms; and to provide simultaneous opening and closing of their respective circuits.
  • FIG. 4 a typical relay, made in accordance with the teachings of theresent invention, is illustrated in an I exploded manner in order to show the interrelationship a thin sheet of electrically insulating material such as an adhesive, a plastic, or the like; or it may be an electrically insulating film, such as an oxide or the like, formed chemically on one or both surfaces of the adjacent materials that form the yoke/switching element interface.
