Definitions

  • the invention is a polarity reversal relay for direct current motors, two relay systems being connected with their contacts in a so-called “H-bridge circuit” according to FIGS. 8 to 10.
  • Relays of this type are preferably, but not exclusively, used in motor vehicles, for example for reversing the polarity of motors for window regulators, door locks, antenna adjustment, seat adjustment and sunroofs.
  • a relay of the type mentioned is already described in US-A-4,816,794.
  • this known relay two electromagnetic systems are arranged side by side, a common pair of mating contact elements being arranged on one side of the double relay.
  • the counter-contact elements must extend over the length of both systems also have twice the length of a single relay unit. Accordingly, the contact space is relatively large compared to the total relay volume.
  • both relay units have bobbins with different designs, which also requires different molds and manufacturing steps for the production.
  • adjustment and coordination between the two relay units are problematic with this arrangement.
  • the object of the present invention is to provide an electromagnetic relay of the type mentioned, in which the space required for the common contact system and, accordingly, for the total volume of the relay can be kept as small as possible. This also means that the number of different individual parts and parts as a whole is kept as low as possible, so as to minimize the costs for production, tools and assembly. The individual parts should be able to be assembled to one another as far as possible without additional fastening elements, with little or no readjustment being necessary.
  • the two common counter-contact elements are therefore arranged in the border area between the two coil bodies or magnet systems; thus the common contact gap only needs the width of a single electromagnetic system.
  • the two coil bodies are connected to one another in this boundary region, which can be done either by interlocking the locking elements of these two coil bodies themselves or by means of the counter-contact elements. Additional fastening parts are therefore not necessary.
  • the counter-contact elements serve to position and hold the two coil bodies in their desired mutual position. This is done, for example, by means of protrusions in the form of barbs and / or by means of spreading spring elements which are in engagement with corresponding fastening elements of the coil former.
  • both bobbins can have an identical shape, as a result of which the production costs can be further reduced.
  • the electromagnetic relay shown in FIGS. 1, 2 and 3 has two electromagnetic systems A and B with an identical configuration, which are connected symmetrically to one another. Therefore, the identical parts in the two electromagnetic systems have the same reference numerals, which are partially supplemented with the letters (A) or (B). Details of the coil form and the fixed counter-contact elements can be seen in FIG. 4.
  • Each electromagnet system has a coil former 1 with a tubular coil carrier 11, a first flange 12 at its upper end and a second flange 13 at its lower end.
  • the coil body 1 is provided with a coil 2, also with a core 10, a yoke 3, an armature 4 pivotably mounted on the end of the yoke 3 and a contact spring 5.
  • the contact spring 5 is connected to the armature 4 and has a rear end 51 which is fixed to the frame 3; thus the contact spring also serves to hold and reset the armature.
  • the yoke 3 is provided with a connection element 31 for the contact spring, and the coil 2 has a coil connection 21 in the usual way.
  • each contact spring has a contact end 52 which extends beyond the movable end 41 of the armature 4; this contact end of the contact spring is asymmetrical with respect to a center line of the armature or a center plane of the electromagnet system.
  • a movable contact piece 53 is attached to the contact end 52 of each contact spring 5.
  • the normally closed contact element 6 has a horizontal contact leg 61 and a vertical connecting leg 62
  • the normally open contact element 7 has a horizontal contact leg 71 and a vertical connecting leg 72.
  • Two normally closed contact pieces 63 and 64 are fastened to the contact leg 61, while two working contact pieces 73 and 74 are attached.
  • each of the first flanges 12 of the coil body 1 has two vertical projections 14 and 15.
  • a first groove 141 and a second groove 142 are provided, while in the projection 15 a first groove 151 and a second groove 152 are formed.
  • Each of these first and second grooves have a depth which corresponds to approximately half the width of the two contact legs 61 and 71.
  • the electromagnetic systems A and B are put together by pressing the first flanges 12 and the second flanges 13 of both bobbins 1 (A) and 1 (B) against one another, with the fixed contact legs 61 and 71 being fastened between them.
  • the contact leg 61 is inserted into the first grooves or slots 141 and 151 of both bobbins 1 (A) and 1 (B), and the contact leg 71 is inserted accordingly into the second grooves 142 and 152 of the two bobbins.
  • the vertical offset (parallel to the respective coil axis) is largely reduced or avoided by a low-tolerance press fit of the contact legs in the respective grooves of the coil body.
  • the barbs 65, 66, 75 and 76 are each designed so that they experience a penetration with an associated projection 14 or 15 of the respective bobbin. As can be seen in FIGS. 2 and 3 and in the enlargement again in FIG. 7, the barbs dig into the side wall of the respective projection 14 or 15. The sharp inner corners of the barbs hold the spool in place when you try to pull it out. Radii on the front edges, on the other hand, make insertion easier the contact leg in the plastic bobbin 1.
  • the barbs 65, 66, 75 and 76 can also have a small twist if required. This design can be seen in FIG. 7 in two different views (see the enlarged detail on the right there).
  • the barbs Due to the twist, the barbs can also be twisted somewhat when inserted. This translates the shape change that is required due to the partial penetration into a movement that rotates the barbs somewhat instead of bending them backwards. This reduces the risk of damage to the contact legs and coil formers during assembly by producing a lower spring rate than that which would occur if one tried to bend the metal in a direction perpendicular to its thickness. By generating the rotation over a length range of the barb instead of a bend precisely at the intersection between the barb and the contact leg, the stress concentration in the contact arm can be reduced.
  • directional lugs 131 are provided which fit into corresponding recesses 132 of the opposite bobbin.
  • a retaining tooth 133 is formed on one outside and a corresponding retaining tooth 134 on the opposite outside of the flange 13 in the vicinity of the boundary region between the two coil bodies.
  • the connecting leg 62 has a claw element with cut-out spreading spring lips 67 and 68, while the connecting leg 72 has corresponding spreading spring lips 77 and 78.
  • the connecting legs 62 and 72 are located between the opposite side gaps between the bent both bobbins.
  • the spreading spring lips 67 and 68 are pressed over the holding teeth 133 and 134 of the two coil bodies on one side, while the spreading spring lips 77 and 78 are pressed over the holding teeth 133 and 134 on the opposite outside. Since the spreading spring lips form a penetration with the holding teeth 133 and 134, the opposite flanges 13 of the two coil formers are locked together; This also ensures a vertical alignment of the two coil formers.
  • FIG. 5 shows the expanding claw on a broken-off detail of the connecting leg 62 alone with a slight modification.
  • the spreading spring lips 67 'and 68' are shown in a sawtooth shape. In this embodiment, the sliding of the spring lips over the corresponding holding teeth 133 and 134 is facilitated.
  • the relay arrangement is arranged on a base plate 8 and enclosed in a cap 9.
  • the housing thus formed is then sealed with a sealant or adhesive in a conventional manner, preferably by a method described in US-A-4,810,831.
  • FIGS. 8, 9 and 10 show different contact configurations when reversing the polarity of a motor M.
  • the normally closed contact pieces and the working contact pieces 63, 64 and 73, 74 are connected together to the mating contact legs 61 and 71, and the movable contact pieces 53 (A) and 53 (B) switch between them according to FIGS. 8 to 10. It is assumed that the normally closed contact element 6 is connected to ground, while the normally open contact element 7 is connected to a direct voltage, for example 14 V.
