Definitions

  • the invention relates to a connector for radiant heaters, such as those used in hotplates with glass ceramic hobs.
  • connecting pieces for radiant heaters are known, which are accommodated in a corresponding section of the carrier shell of the radiant heater.
  • the connecting pieces can be inserted into the cutout of the carrier shell in two different positions rotated by 180 ° using a groove guide. In connection with the use of two different connection lugs, four different positions of the connector tongues can thus be achieved for establishing the connector connection.
  • the task for the invention is to remedy the shortcomings inherent in the known solutions.
  • this object is achieved in that the welding lugs arranged on the flat-shaped connecting lugs, which at the same time serve as a wrap and thus as strain relief, have the same length for the different installation positions, starting from the imaginary axis of rotation of the connecting piece. This ensures that the welds are exactly at the same place in both installation positions of the connector. This means that connecting wires of the same length and in the same position can be used for all installation variants. The penetrations of the edge of the insulating body remain unchanged in the same place.
  • Another feature of the invention is that assembly aids for self-fixing of the connecting wires for the welding process are provided on the inner front of the connector facing the radiant heater. A special additional fixation of the connecting wires is thus unnecessary.
  • pontoon-like centering pieces on which the connecting wire independently rolls against the corresponding welding lug, in connection with upper and lower stop surfaces for longitudinally fixing the connecting wire have proven to be particularly suitable.
  • the centering pieces are mirrored above and below.
  • connection lugs with wedge-shaped recesses are provided for insertion into the connector base body, each optionally at least in three have different tongues arranged in different positions.
  • the connector tongues are optionally arranged vertically, horizontally or obliquely at an angle of 20 ° to 70 °, preferably at an angle of 45 ° to the position of the welding lugs, so that taking into account the two installation positions by rotating the connector by 180 ° in total at least six Connection positions are achieved, which significantly increases the universality with regard to the installation options of the radiant heater.
  • the entire connector was constructed deeper into the radiant heater.
  • the welding points which connect the connecting wires and the welding tabs, were arranged invisibly from below under the fiber ring.
  • the overall depth of the connector was significantly reduced. This measure also significantly improves the installation conditions of the radiant heater and minimizes the distances between the radiant heaters, especially in built-in stoves of complete kitchen units.
  • the connector consists of a ceramic connector body 1 and a number of inserted lugs 7 , which correspond to the number of contacts required.
  • the connecting lugs 7 consist of a wrap-around 6 , two, an upper and a lower welding lugs 8, 9 and have a wedge-shaped recess 22 for the web 23 .
  • the connecting lugs 7 are inserted with the wrap 6 , which also serves as a welding lug 8 or 9 , into the guide grooves 15 , at the same time the twisting tab 5 is pushed through the slot 19 and rotated over the clamping surface 20 .
  • the wrap 6 is not bent after insertion.
  • the centering wedge 18 in connection with the wedge-shaped recess 22 ensures the adjustment of the connecting lugs 7 in the connector base body 1 and for strain relief.
  • the connector thus preassembled is inserted into the cut-out edge of the carrier shell 14 in a known manner by means of the receiving grooves 21 .
  • the connecting wire 10 is inserted, which fixes itself through the pontoon-like centering piece 16 and the stop surface 17 and is brought into the correct position in relation to the welding lug 8 in order to be able to carry out the welding.
  • connection tabs 2, 3, 4 are optionally provided on the connecting lugs 7 , onto which the connecting plugs are pushed.
  • the welding lugs 8, 9 located on the connecting lugs 7 measured from the imaginary axis of rotation BB, each have the same length in order to always have the welding points between the welding lugs 8 and 9 and the connecting wire 10 at exactly the same location when the connecting piece is rotated through 180 ° .
  • connection lugs 7 with differently arranged plug tongues 2, 3, 4 are provided, as can be seen from FIGS. 1, 5, 6 and 7 .
  • three positions of the plug tongues 2, 3, 4 are shown, namely those in a horizontally lower, vertically lower and 45 ° inclined lower position.
  • further positions (not shown) of the connector tongues 2, 3, 4 are obtained, namely a horizontally upper, a vertically upper and an oblique upper position of the connector tongues 2, 3, 4.
  • the assembly aids namely the pontoon-like centering pieces 16 and the abutment surfaces 17 , are each arranged on the connector base body above and below.
  • the connecting piece, guide groove 15 Due to the special design of the connecting piece, guide groove 15 , with welding lugs 8, 9, centering piece 16, stop face 17, connecting wire 10 and thus also the welding points between welding lugs 8 and 9 and connecting wire 10 , lie within the line between the grooves 21 Outer radius of the carrier shell 14 .
  • the welding points are covered by the fiber ring 13 and the connecting wires 10 through a recess in the insulating body edge 12 or a recess in the fiber ring, which is placed on the insulating body 11 , to the heating coils.
