Definitions

  • the present invention relates to a control module of an electrical apparatus, and a heating device, in particular for a motor vehicle, comprising such a control module.
  • the present invention further relates to a method of assembling such a module.
  • the patent application EP 1 282 191A2 discloses a conductive member provided with a skirt receiving a rod.
  • the invention applies in particular to the technical field of additional electric heating devices for motor vehicles.
  • Such heaters are particularly used in the first minutes of starting a motor vehicle, when the engine is not hot enough to ensure the supply of hot air in the passenger compartment of the vehicle.
  • This heating time is for example between 15 and 20 minutes for a Diesel type engine.
  • An additional heating device generally comprises a support frame on which are mounted parallel heating modules arranged to be traversed by a flow of air to be heated.
  • Each heating module comprises two electrodes between which are placed resistive elements of the positive temperature coefficient (PTC) type. Two opposite heat sinks are attached to the electrodes, so as to increase the exchange surface with the air flow to be heated.
  • PTC positive temperature coefficient
  • Each heating module thus comprises a positive terminal.
  • the positive terminals are electrically connected via the same electrically conductive connecting member to the positive terminal of a battery.
  • the negative terminal of each heating module is electrically connected to the negative terminal of the battery.
  • control module also called "Driver”.
  • the control module is mounted in a housing fixed to the support frame.
  • connection between the rod and the member does not allow the use of large electrical powers and is limited to powers below 1000 Watts because of the reduced contact between the rod and the organ which is only done by the inner surface of the orifice in contact with a corresponding surface of the rod.
  • the invention aims in particular to provide a simple, effective and economical solution to these problems.
  • the force-fitting of one end of the rod in a skirt formed around the periphery of the orifice makes it possible to increase the contact surface between the rod and the connecting member, which allows the use of electrical appliances of higher power, for example 1200 Watts.
  • the increase of the contact surface allows a good control of the insertion force of the rod in the skirt, which is not possible when the contact surfaces are reduced as in the prior art.
  • connection of the rod to the member also ensures a better mechanical connection of the two parts.
  • the skirt is formed on a face of the member opposite to that from which the rod extends.
  • the free end of the rod is substantially flush with the free edge of the skirt.
  • the stem comprises a radial shoulder abutting on the member thus making it possible to control the positioning in force of the rod in the member.
  • the rod comprises at least one annular groove in which the electrically insulating lining extends, in order to improve the mechanical connection of the rod to the lining which is integral with the body.
  • the skirt is advantageously formed in one piece with the member which is made for example by a jogging operation.
  • the orifice, the skirt and the stem have a circular section.
  • the skirt has a diameter of about 4 mm and a height of between 1.5 mm and 2.5 mm.
  • the invention also relates to a heating device, in particular for a motor vehicle, comprising a module as described above and at least one heating module, one terminal of which is electrically connected to the aforementioned member.
  • the figure 1 represents an additional electrical heating device 10 according to the prior art, intended to equip a motor vehicle.
  • a heating device 10 is especially used in the first minutes of use of the motor vehicle, when the engine is not hot enough to ensure the supply of hot air into the passenger compartment of the vehicle.
  • This device 10 comprises a support frame 12 of parallelepiped shape on which are mounted heating modules 14 parallel and arranged to be traversed by a flow of air A to be heated.
  • the heating modules 14 are controlled by means of a control module 16 ( figure 2 ) or "Driver" mounted in a housing 18 fixed to the support frame 12.
  • Each heating module 14 comprises two electrodes 20, 22, one of which corresponds to a positive terminal and the other to a negative terminal, between which resistive elements of the positive temperature coefficient type are placed.
  • Two opposed heat sinks 24 are fixed on the electrodes, so as to increase the exchange surface with the air flow to be heated.
  • the heat sinks 24 are for example formed of folded or corrugated metal ribbons.
  • Each heating module 14 thus comprises a positive terminal electrically connected to the positive terminal of a battery and a negative terminal electrically connected to the negative terminal of the battery via a printed circuit board 26 on which are soldered or mounted various electrical or electronic components 28.
  • the electrical connections between the electronic components 28 of the control module 16, the heating modules 14 and the battery are provided by electrically conductive members.
  • three conductive members 30a, 30b, 30c connect the negative terminals of the heating modules 14 to the printed circuit board 26.
  • Another conductive member 32 connects the positive terminal of the battery to the positive terminals of the various heating modules 14.
  • the various conductive members 30a, 30b, 30c, 32 are mechanically connected to one another and electrically insulated from each other by a plastic-molded over-molded packing 34 which acts as a support so that said conductive members 30a, 30b , 30c, 32 and the liner 34 form a unitary assembly.
  • the liner 34 is fixed on the printed circuit board.
  • the conductive member 32 is connected to the positive terminal of the battery via a metal rod 36, one end of which is inserted and held in an orifice of the member 32 ( figures 2 and 3 ).
  • the rod comprises two annular grooves 40 located on either side of the conductive member 32. Apertures 38 are formed in the thickness of the member 32 so as to allow the passage of the insulating lining 34 through the body. in the grooves 40 of the rod 36.
  • the rod 36 is in contact with the member 32 only by its surface 42 in contact with the inner surface 44 of the orifice, which is insufficient to transmit the electrical energy required for the operation of apparatus high power, especially greater than 1000 Watts.
  • the figure 4 represents in isolation a conductive member 46 according to the invention which comprises a first 48, a second 50 and a third 52 tabs substantially parallel to each other, each tab being intended to be connected to a positive terminal of a heating module 14 described with reference to the figure 1 .
  • the first 48, second 50 and third 52 tabs are interconnected by a central portion 54, one end carries a fourth tab 56 extending away from the third tab 52 and substantially perpendicular thereto.
  • the fourth leg 56 of the member 46 comprises an orifice 58 whose periphery comprises a skirt 60 of substantially cylindrical shape which extends in the same direction as the first, second and third legs from the fourth leg 56.

  • the rod 59 comprises a radial shoulder 62 allowing abutment of the rod 59 on the fourth leg 56 of the member 46, this shoulder 62 being positioned so that the mounting end face of the rod 59 is substantially flush with the free edge of the cylindrical skirt 60.
  • a counter-punching operation is performed on the end face of the rod 59 to locally compress the material of the rod 59 on the inner face of the skirt 60, which ensures a good mechanical strength of the rod 59 on the member 46 and a better contact with the skirt 60 for good transmission of electrical energy.
  • the end of the rod 59 also comprises an annular groove 64 formed to be positioned facing the face of the fourth tab 56 opposite the skirt 60.
