Definitions

  • This invention relates to a tap/switch combination for civil range electrical appliances, comprising an electric current tap provided with receptacles for an electric consumer plug, and an electric switch provided with mechanical linkages for applying or cutting off a power supply to said tap, the operation of said mechanical cut-off linkages being controlled by the insertion and withdrawal movements of the plug into/out of said tap and being brought about through an interlock mechanism extending between the tap receptacles and the mechanical cut-off linkages.
  • interlock devices are enforced by regulatory bodies to protect persons and properties in such particular environments as indoor spaces where a potential fire or explosion danger exists, construction sites, and damp or wet places.
  • Manipulating an electric plug under a load may, in fact, constitute a hazard for the user, whether by arcing, or flashing and deterioration of the tap inlet holes, or wear and cratering of the pins, or damaging the delicate receptacle protecting arrangement in the instance of taps equipped with shutters.
  • a tap/switch combination including an electric current tap with receptacles for an electric consumer plug and an electric switch with mechanical linkages for applying or cutting off the power supply to said tap, wherein the operation of said mechanical cut-off linkages is controlled by the insertion and withdrawal movements of the plug into/out of said tap.
  • a tap/switch combination including an electric current tap with receptacles for an electric consumer plug, an electric switch with mechanical linkages for applying or cutting off a power supply to said tap and an interlock mechanism for acting on said mechanical linkages in the off-position of the switch when the plug is not inserted into said tap.
  • the technical problem underlying this invention is that of providing a tap/switch combination for civil range electrical appliances which has such constructional and operational characteristics as to obviate the drawbacks of the cited prior art.
  • this invention provides a tap/switch combination as indicated, wherein said interlock mechanism comprises a lever journalled on the interior of said tap and being displaceable angularly from an operating position, where a first arm of the lever lies close to and transversely of at least one of said receptacles and a second arm of the lever is coupled to said cut-off linkages, to an inoperative position where said second arm is uncoupled from said cut-off linkages, and a spring-loaded means effective to hold the lever in the operating position thereof, said lever being displaceable angularly on the plug being inserted into said tap.
  • a tap/switch combination according to the invention and comprising a current tap 2 and a switch 3, specifically intended for mounting within a frame, omitted from the drawings, for a flush-mounted or enclosed box civil range electrical appliances.
  • the combination 1 has a substantially parallelepipedal outward shape, and a tap body 4 and switch body 5 defined therein which are both box-shaped and laid close against each other along two corresponding walls thereof; for convenience of illustration, these two side-by-side walls will be regarded as a single wall designated by the reference numeral 6.
  • a pair of poles Placed within the body 5 of the switch 3 are a pair of poles, not shown, one of which is located close against the wall 6, and the other at an opposed wall 5a; provided along both poles are a respective fixed contact 7 carried on the body 5 and a respective moving contact 8, mounted on a moving contact holder assembly 9 to be explained hereinafter.
  • the switch 3 also includes mechanical cut-off linkages, generally designated 10, which are supported on the body 5; the cut-off linkages 10 include a tumbler key 11 associated with the moving contact holder assembly 9.
  • the moving contact holder assembly 9 comprises a moving contact holder body 12 which includes electric paths and non-conductive portions and has, mounted on one end thereof, the moving contacts 8, which are thus held in mutually parallel and spaced-apart relationship. Between the key 11 and the moving contact holder assembly 9, there is provided a spring-biased toggle mechanism 13, known per se.
  • the mechanical cut-off linkages 10 further comprise a spring-loaded rest lever 14 which is journalled in the body 5 and displaceable angularly from a first position to a second position, as made clear hereinafter.
  • Said rest lever 14 includes, in turn, two arms 14a, 14b lying substantially at right angles to each other.
  • the larger arm, 14a has a pair of lugs 15 and 16 facing the wall 6 and opposed wall 5a, respectively; moreover, the arm 14a is formed with a slit 17.
  • the smaller arm, 14b With the rest lever 14 in its first position, or position of consent to contact making, the smaller arm, 14b, is adapted to provide a bearing point for the moving contact holder body 12, purposely formed with a rest dog 12a, and therefore to enable the switch 3 to make.
  • the rest lever 14 is constantly biased toward said position of consent to contact making by a spring, not shown.
  • ammeter coil 18 supported on the switch body 5 at the wall 5a; the ammeter coil 18 has a set number of turns of a large cross-sectional area wire lead and is provided with a cylindrical pusher 19 operative to engage with the lug 16 on the occurrence of shorting currents and to move the rest lever 14 accordingly to its contact break position, thus releasing the contact holder assembly 9 and causing the switch 3 to break.
  • the switch 3 also includes an additional arm 20, formed integrally with the rest lever 14 and extending parallel to the second arm 14b.
  • the additional arm 20 is provided with an adjustable contact tip 20a and adapted for engagement by a bimetallic strip thermal relay, not shown, to move the rest lever 14 into its contact breaking position.
  • the current tap 2 has three receptacles 21,22,23 formed of corresponding bushings 24,25,26 which are supported on the tap body 4 in mutually spaced-apart relationship.
  • the middle receptacle 22 is, in particular, intended for grounding the current tap 2.
  • Said receptacles, 21,22 and 23, are adapted to receive respective prongs 27,28 and 29 of an electric plug 30, known per se.
  • the tap/switch combination 1 includes an interlock mechanism 31,32 extending between the receptacles 21,22,23 of the tap 2 and the cut-off linkages 10 of the switch 3.
  • the above-mentioned interlock mechanism comprises a substantially crank-like lever 31 journalled on the interior of the body 4 of the current tap 2 and being displaceable angularly from an operating position to an inoperative position, as explained more clearly hereinafter.
  • the interlock mechanism further comprises a spring-loaded means 32 arranged to act on the lever 31 for holding it in its operating position.
  • the lever 31 includes a lever body 33 of C-like configuration which is provided with a pair of pins, both indicated at 34, facing each other in aligned relationship.
  • the pins 34 fit into respective seats 35 formed in the tap body 4 close to the wall 6.
  • the lever 31 also has a first arm 36 and second arm 37 extending substantially at right angles to each other and being secured to the lever body 33; more specifically, the first arm 36 consists of a lug extending perpendicularly to the lever body 33 in the proximity of the intermediate receptacle 22 to the receptacles 21 and 23, whilst the second arm 37 extends aligned to one of the sides of said C-shaped body 33.
  • the second arm 37 extends through an aperture 38 formed in the wall 6, and that with the lever 31 in its operating position, the first arm 36 extends transversely of the receptacle 22 and the second arm 37 is active on said cut-off linkages 10.
  • the second arm 37 will be active on the first arm 14a of the rest lever 14, thus moving it angularly into the aforesaid contact breaking position.
  • the first arm 36 With the lever 31 in said inoperative position, the first arm 36 will be positioned outside the receptacle 22 to enable introduction of the plug 30, and the second arm 37 will be uncoupled from the cut-off linkages.
  • the spring-biased means 32 operative to constantly bias the lever 31 toward its operating position, is preferably composed of a pair of parallel lugs 39 formed from an elastically deformable material and being supported at one end by the lever body 33 and having the other, free end in pushing contact with the wall 6.
  • the lever body 33, first arm 36, second arm 37, and aforesaid lugs 39 are a one piece construction, being preferably molded as such from a synthetic plastic material.
  • the tap/switch combination 1 operates as set forth herein below.
  • the lever 31 With the plug 30 removed from the current tap 2 of the tap/switch combination 1, i.e. with the prongs 27,28,29 out of the receptacles 21,22,23, the lever 31 will be held in its operating position by the spring-loaded means 32, with its first arm 36 set to interfere with the receptacle 22 and its second arm 37 to act on the cut-off linkages 10 (re. Figures 4 and 5).
  • the rest lever 14 will be held, therefore, in its contact breaking position, and the moving contacts 8 at a set distance away from their corresponding fixed contacts 7.
  • the prong 28, which corresponds with the receptacle 22 will contact the first arm 36 of the lever 31 (re. Figures 6 and 7) and cause the lever 31 to be displaced angularly from its operating position to its inoperative position where the second arm 37 is uncoupled from the rest lever 14 of the cut-off linkages 10.
  • the switch 3 can be brought to a contact making condition.
  • the first arm 36 of the lever 31 would consist (re. Figures 8 and 9) of three lugs 36a,36b,36c set parallel at a mutual distance apart, of which the extreme lugs 36a and 36c lie at the receptacles 21 and 23.
  • the current tap/switch combination of this invention affords the primary advantage that a plug can be pushed into and pulled out of a current tap always in an open circuit condition, regardless of the switch setting. Thus, the risk of arcing and flashing is avoided which, as is known, would result in both the tap receptacles and prongs of the consumer plug becoming deteriorated.
  • the tap/switch combination according to the invention can be considerably more reliable than conventional switch taps for civil electric appliances, it affording complete and automatic safety especially for the incompetent user, in full conformity with the lawful provisions mentioned in the preamble.
