Definitions

  • the present invention relates to an energy regulator of the kind which incorporates a bimetal element.
  • a common form of heating element for such a regulator is a ceramic substrate thick film heater.
  • Current methods of making electrical connection to ceramic substrate heaters have shortcomings in maintaining a reliable electrical connection at high ambient temperatures and heater power levels. Soldered connections are difficult to fuse (e.g. Ag to CuNi) and creep and melt points of HMP solder limit maximum safe operating temperatures. Mechanical rivet/tape compression types are prone to intermittent, i.e. high resistance, connection. Spring wiper connection types suffer from stress relaxation as well as friction and wear. The magnitude and degree of change of force experienced can adversely affect control performance.
  • a first aspect of the present invention provides a method of making an electrical connection to a ceramic substrate heater comprising a resistor track, a conductor pad for the resistor track, and an electrical lead making electrical connection to said conductor pad, the method comprising welding said lead to said conductor pad by ultrasonic welding.
  • a ceramic substrate thick film heater comprising a resistor track in electrical contact with a conductor pad and an electrical lead making electrical connection to said conductor pad, whereby the lead is ultrasonically welded to the conductor pad.
  • the third cam follower is not directly attached to the contact arm which it actuates.
  • a "loose" cam follower is supported on the regulator case by support and guide means.
  • a fourth aspect of the present invention now provides an energy regulator comprising a bimetal element comprising a primary limb responsive to a heating element and a compensator limb for compensating for the effects of ambient temperature fluctuation, wherein the primary and compensator limbs are formed of the same piece of bimetal and the bimetal element is mounted on a flexible pivot member.
  • the design therefore has the advantages of giving optimum compensation, elimination of bimetal constant variation problems and also enabled a low profile design of control to be considered.
  • the primary and compensator limbs are integral, e.g. formed by splitting a bimetal strip lengthways from one end along a part of its length.
  • This bimetal strip can be supported at its unsplit end.
  • the unsplit end of such a split bimetal strip can be supported on the pivot.
  • the primary and compensator limbs are approximately at right angles or otherwise in a mutual V configuration.
  • a calibration feature is provided for determining the particular regulator setting, i.e. percentage output, (for a predetermined cam position) at which the energy regulator turns on or off.
  • This may be constituted by an adjustment screw device protruding through a free end of the primary leg, terminating in an actuating member.
  • an adjustment feature could be provided elsewhere.
  • a screw adjustment with protrusion could be put through a free end of the compensator leg to bear upon the cam surface, i.e. to act as the cam follower.
  • the regulator 1 comprises a base 3 in which the constituent parts of the regulator are housed.
  • the compensator strip Remote from the base region 15, the compensator strip has a bend 41 so that it is angled towards the cam element 37 and terminates in a cam follower 43 which bears against the cam surface 39.
  • the position of the cam surface 39 contacted by the cam follower 43 alters the orientation of the compensator bimetal strip 13 relative to the pivot spring 17 and so also, the orientation of the primary bimetal strip 11 relative to the pivot spring.
  • the position of the calibration screw 33 relative to the switch mechanism 6 is also varied.
  • the two limbs are formed from a single strip split laterally with the unsplit remnant at one end forming the base region 15 which is mounted on the pivot spring.
  • the metal on the top side (facing the cam element 37) of the primary strip 5 is on the reverse side (not facing the cam element) of the compensator strip 13 and vice versa.
  • the tape 45 is connected to the link clip 53 by means of a U-shaped portion 68 and a clip arrangement 69 which could be strengthened by means of spot welding or ultrasonic welding.
  • a third cam surface 89 which also rotates in accordance with rotation of the common shaft 87.
  • a third cam follower 91 bears upon the third cam surface 89. Further details of the cam follower can be seen from Figures 4, 5 and 6.
  • the third cam surface is configured to open and close the contacts 98, 99 of the third switch 75 through the agency of the third cam follower 91. It will be appreciated that the opening and closing of the second and third switches 73, 75 is independent of each other and also independent of the opening and closing of the contacts 2, 4 in response to the operation of the bimetal strip 5 and the action of the primary cam surface 39.
  • FIG. 11 The arrangement of Figure 11 is the same as that of Figure 10 except that a further switch element is provided. Thus, the arrangement is that shown in Figure 1 and the same reference numerals are used for the switch contacts as in the latter drawing.
  • the switch contacts 77, 79 are connected in the same way as contacts 117, 119 in the arrangement of Figure 10 and therefore operate in the same way.
  • the other pair of contacts 75 are in series between the mains supply 113 and a signal lamp 121 which can be switched independently of the isolation contacts 77, 79 and the contacts 27, 31 operated by the bimetal element 5.
  • the cam follower 91 operates movable contact arm 97 and operates third switch 75 in accordance with its own cam arranged on the common shaft.
