Definitions

  • the invention relates to a bridge rectifier for three-phase generators, in particular for supplying the electrical system of motor vehicles according to the preamble of the main claim.
  • Rectifier assembly attached, so that only their DC output form the terminals of the generator, to which the connection cable of an accumulator battery of the motor vehicle electrical system are connected.
  • Rectifier arrangement which often occurs due to the charging of batteries via incorrectly polarized battery charging devices, not only the generator or the rectifier arrangement is destroyed, but also it can also cause further thermal damage.
  • Rectifier arrangement between the connections of the plus and minus diodes of the three rectifier bridges to arrange fuses. These are formed by loop-shaped conductor sections which are bent out of recesses in the circuit board of the rectifier arrangement and which melt in the event of an electrical overload, but can be temporarily repaired by twisting the ends together. After a fuse has tripped, the rectifier arrangement must therefore be completely replaced later. If this is not done, the risk of destruction of the generator and the risk of consequential damage increase considerably.
  • the aim of the present invention is to ensure the protection of the generator and the bridge rectifier in the event of an electrical overload or short circuit within the narrowest possible tolerance range of the maximum permissible current.
  • the bridge rectifier according to the invention with the characterized features of the main claim has the advantage that the response value of the fuse can be kept within narrow tolerance limits by appropriate choice of material and precise, simple cross-sectional dimensioning of the fuse element inserted between the conductor ends of the connecting conductors, so that the bridge rectifier has a correspondingly higher power density is to be interpreted.
  • Another advantage is that when a fuse responds, the bridge rectifier can first be replaced and can be used again as a replacement rectifier by replacing the blown fuse element.
  • Form security strips the ends of which are electrically connected to the conductor ends of the circuit board.
  • a thermally and mechanically stable connection of the conductor ends of the circuit board to the fuse strips results from the fact that the fuse strip is soldered or welded to flattened end sections of the connecting wire of the circuit board consisting of round wire.
  • the securing elements each have one to surround the closed container and to fill the container with quartz sand.
  • the containers are to be advantageously fastened to the plate-shaped insulating body of the circuit board.
  • FIG 1 shows the circuit of the three-phase generator with the
  • FIG. 2 shows a cross section through the structural design of the bridge rectifier
  • Figure 3 shows a section of the circuit board of the
  • Figure 4 and Figure 4 shows the same securing element from the front in a container.
  • AC generator 11 is shown for motor vehicles, which are combined at one end to form a star connection and are connected at the other end to a rectifier bridge 12, 13 and 14 of a bridge rectifier 15.
  • a circuit board 16 is used to interconnect the three phases 10 with the three rectifier bridges, each of the three rectifier bridges consisting of a minus diode 17 and a plus diode 18 connected in series.
  • the minus diodes 17 are pressed into a minus heat sink 19 on the anode side and the anode connections of the minus diodes 17 are thus combined by the minus heat sink 19 to form a minus connection 20.
  • the plus diodes 18 are pressed into a plus heat sink 21 on the cathode side.
  • the cathode connections of the plus diodes 17 are thus combined in this heat sink 21 and connected to a plus connection 22 of the bridge rectifier 15.
  • the circuit board 16 consists of a substantially plate-shaped insulating body 23 in which a plurality of connecting conductors 24 are embedded, which the plus and minus diodes 17, 18 of each rectifier bridge 12, 13 and 14 with each other as well as connect to phases 10 of the three-phase generator.
  • a fuse 25 is arranged in each rectifier bridge 12, 13 and 14.
  • the fuses 25 are dimensioned such that they melt in the rectifier bridges 12, 13 and 14 when the permissible maximum direct current is exceeded.
  • the bridge rectifier 15 is attached to the rear of the three-phase generator 11 according to FIG. Its structural design is such that first the minus heat sink 19 rests on the housing of the three-phase generator 11 which is at ground potential. This is followed by an insulating plate 26, then the plus heat sink 21, then the circuit board 23 and finally a protective cap 27. These parts are fastened to the generator by screws 28.
  • the positive connection 22 is formed here by a connecting screw 22a inserted in the positive heat sink 21.
  • the fuses 25 are each formed according to FIGS. 3 and 4 from two outwardly angled conductor ends 24a of the connecting conductors 24 and a fuse element 29.
  • the conductor ends 24a are sections of the connecting conductors 24 made of the insulating body 23
  • Circuit board 16 bent out at a right angle so that they protrude above the insulating body 23.
  • These conductor ends 24a are bridged by the securing element 29 in the form of a metal strip, in that the ends 29a of the securing element 29 are electrically connected to the conductor ends 24a.
  • the ends 29a of the securing element 26 are soldered to the flattened end sections 24b of the connecting conductors 24 consisting of round wire. If the spatial conditions allow this, they can also be welded on. If necessary, the very sensitive securing elements 29 can also be protected against corrosion or mechanical damage according to FIG. 4 with a closed container which completely surrounds the conductor ends 24a with the securing element 29.
  • the pot-shaped container 30 can be made in a simple manner from a plastic and glued to the surface of the insulating body 23 of the circuit board 16. In order to keep short-term temperature changes from the outside of the fuse element 29 and thus optimize the response behavior of the fuses 25, the container 30 is still filled with quartz sand 31.
  • the star point of the three phases 10 can also be additionally secured by a fuse element 25.
  • a further connecting conductor 24 is embedded in the plate-shaped insulating body 23 of the circuit board 16, which the connects three phases 10 to a star point.
  • a fuse 25 can also be provided in this connecting conductor in the same way.
  • the securing element 29 can also be designed to be exchangeable. In this case, the connections of the securing element are to be connected to the conductor ends 24a by clamping.

Abstract

L'invention concerne un redresseur en pont pour alternateur à courant triphasé, en particulier pour l'alimentation du réseau de bord de véhicules automobiles. Ce redresseur en pont est constitué de diodes de redressement et d'une platine à circuit formée par un corps isolant (23) sensiblement en forme de plaque, dans lequel plusieurs conducteurs de connexion (24) sont incorporés entre les diodes des redresseurs montés en pont. Des parties de ces conducteurs de connexion (24) sont pliées à l'extérieur du corps isolant et constituent des fusibles (25) qui fondent en cas de surcharge électrique. Pour que les tolérances les plus faibles possible soient obtenues lors de la réaction des fusibles (25), ces derniers sont formés chacun de deux extrémités (24a) des conducteurs de connexion (24) coudées vers l'extérieur et d'un élément fusible (29) qui relie par pontage ces extrémités.
