Definitions

  • a relay with such a structure is in EP 0 281 950 B1.
  • the connection configuration the flat plug on the underside of the base corresponds to the Standards for automotive relays are distributed.
  • the insulation is between the load connections and to the coil problematic.
  • the aim of the present invention is to provide a relay of the input mentioned type so that it is despite simple Manufactured and suitable with a narrow and compact structure is to switch very large switching powers on and off or toggle, with the necessary insulation of the Load connections can be implemented in a simple manner.
  • the load connection elements can in in this case either embedded in the material of the base be or in separate pockets of the base or the insulating wall to the bottom of the relay, where they preferably end in mutually isolated chambers.
  • the relay according to the invention is in an advantageous embodiment formed as a bridge contact relay, the on the contact spring attached to the anchor at its free, via the movable end of the armature projecting end portion fork-shaped is split into two spring arms, each of the spring arms each between two fixed mating contact elements is switchable and both spring arms with each other connected via a conductor strip made of highly conductive metal are; in this case, each of the two spring arms carries its own movable end section two against each other in the transverse direction the contact spring offset contact pieces on opposite Surfaces, and those with each other on the same On the surface side, aligned clock pieces of both spring arms act each with a pair of counter contacts as a bridge closer or together as a bridge opener.
  • This offset arrangement of the NO contact pieces the NC contacts on the common switch spring the manufacturing process is facilitated, the total contact height on the spring surface will decrease even if the individual contact pieces with each other by strands or tapes be connected from highly conductive material, and in particular no contact rivets are to be applied coaxially to each other.
  • the offset arrangement also enables equalization in the arrangement of the mating contact elements on this Way, also with favorable use of space and mutual Insulation attached and led to the connection side of the relay can be.
  • the contact spring longitudinal axis adjacent contact pieces both spring arms on the same surface side, preferably towards the anchor are arranged so that they are the Form normally open contacts, while the respective outer contact pieces also on the same surface side, namely are preferably arranged away from the anchor and accordingly form the normally closed contacts.
  • the relay shown in Figures 1 to 4 has one Socket 1, which is the bottom side and the connection level of the relay Are defined.
  • a magnet system with a Coil 2 which is carried by a bobbin 3, one in the coil axially arranged core 4 and an angled Yoke 5 arranged, the coil axis parallel to the bottom side of the base 1 stands.
  • the coil is rectangular or oval cross-section standing upright on the base arranged, which results in a narrow design of the relay.
  • the core 4 is partially indicated by dashed lines in FIG. 2, because it is not visible inside the coil. He owns a T-shaped cross section with a widened Pole end 4a, whereby an enlarged pole area is obtained. If necessary, it could also be upset.
  • the other core end 4b is connected to a first yoke leg 5a, while the second yoke leg 5b on the long side extends next to the coil 2.
  • the yoke 5 stands with its Main sheet levels of the two legs 5a and 5b perpendicular on the bottom side of the base 1. Are on the yoke leg 5b in addition, two fastening pins 5c are formed on the bottom serve to attach the magnet system and for example can be scored in recesses of the base 1.
  • the magnet system is completed by an anchor 6, which is stored on the free vertical edge of the yoke leg 5b and a working air gap with the pole end 4a of the core forms.
  • an anchor 6 On the armature is a contact spring 7, for example fixed with rivets 8 or welding spots.
  • she also acts as a return spring and has a return arm 7a suspended on a holding pin 5d of the yoke leg 5b.
  • the spring corresponds to known systems.
  • the end section is the contact spring 7 in two spring arms 9 and 10 split fork-like.
  • Each of the spring arms is also at the free end again with a cross leg 11 or 12 provided so that it receives a total T-shape.
  • Both cross legs 11 and 12 are each with two holes 13 for receiving contact pieces intended.
  • These contacts are on the Cross legs used from different sides. So are on the inner, facing ends of the cross legs 11 and 12 on the contact pieces 14 and 15 respectively the side facing the anchor so that they Form NO contacts.
  • At the outer ends of the cross legs 11 and 12 are correspondingly outward contact pieces 16 and 17 placed as NC contacts.
  • All contact pieces are in the rest of each other via connecting elements made of highly conductive material, preferably made of Copper, connected. In this way, switching and guiding enables high currents without the contact spring 7 itself must be designed to carry these high currents. It can therefore be made of a spring material relatively less Conductivity, for example made of steel, and so only designed with regard to the required spring properties will.
  • the contact pieces 14 and 15 are used to conduct current connected via a U-shaped copper strand 18, which therefore also the two spring legs 11 and 12 flexible and with high Conductivity connects.
  • the contact pieces 14 and 16 on the Cross legs 11 are via a copper rail 19 and the contact pieces 15 and 17 on the cross leg 12 are over a Copper bar 20 also connected in a highly conductive manner.
  • the contact spring with its four movable contact pieces 14, 15, 16 and 17 works with four mating contact elements, namely the NO contact elements 21 and 22 with the Contact pieces 23 and 24 and with the break contact elements 25 and 26 or their contact pieces 27 and 28 together.
  • the mating contact elements are each via a connection element anchored in the base 1, namely the counter-contact element 25 via a connecting element 29, the mating contact element 21 via a connection element 30 and the mating contact elements 22 and 26 via a common connection element 31. Since this connection element 31 with both a normally open and a A normally closed contact results in a switchover function of the relay. But it would be conceivable if the connections were separated also a normally open or normally closed function.
  • connection elements 29, 30 and 31 are all in one plane and are so together due to the appropriate length and angle adapted that the fixed contact elements 21, 22, 25 and 26 the corresponding contact pieces of the contact spring 7 face each other.
  • this base is perpendicular to the floor Insulating wall 32, which for the individual connection elements has vertical pockets 33, 34 and 35 which up in correspondingly graded wall elements are open.
  • the connection elements are additionally compared to the Coil 2 insulated. These open at the bottom of the base Pockets 33, 34 and 35 in corresponding connection chambers 36, 37 and 38, which are separated by partitions 39 of the base 1 are shielded and insulated. So the connection element opens 29 into the connection chamber 36, the connection element 34 in the connection chamber 37 and the connection element 31 into the connection chamber 38.
  • connection elements with perpendicular to their main plane Provide bolts 40 which serve as cable connections.
  • Bolts 40 are with the connecting elements 29, 30 and 31st connected for example by riveting or pressing.
  • the stability of the base 1 is increased by an additional one End wall 41, which is perpendicular to the insulating wall 32 is perpendicular to the base plane or to the floor.
  • a cap By Place a cap, not shown, on the base 1 a closed housing is formed.
  • the coil 2 are in the base also through coil connection elements 42 and 43 Plugged in, between which another component 44 is connected, for example a diode.
  • the base 1 is initially shown in FIG with the fixed mating contact elements or their connecting elements 29, 30 and 31 equipped, also with the Connection elements 42 and 43 and the component 44.
  • the magnet system On this Base assembly is the magnet system with the coil 2 and placed on yoke 5 and fastened.
  • the armature 6 is mounted with the contact spring 7 so that the Normally open contact pieces 14 and 15 the fixed contact pieces 23 and 24 face each other while the break contacts 16 and 17 the fixed contact pieces 27 and 28 face each other.
  • the arrangement of the normally open contacts on the inside of the Spring arms 11 and 12 and the corresponding arrangement of the break contacts on the outside has the further advantage that a softer spring characteristic curve for the opener via the torsion of the spring takes effect.
  • the spring arms 9 and 10 softer in the longitudinal direction bend because of the rear-facing arrangement the rivet 8 during the closing movement from the anchor edge are freely movable.
  • connection elements 55 and. are also examples in this case 56 in pockets 53 and 54 isolated from each other, however in one level led to the bottom of the pedestal where they were in against each other shielded connection chambers with corresponding Bolts 40 are provided.
  • Figure 6 shows a further modification.
  • this case owns a base 61 in an insulating wall 62 two pockets 63 and 64, in which an anchoring element 65 or 66 is anchored is.
  • Each of these connection elements is in one piece molded counter-contact element 67, both in one Level (only partially visible) and one each Wear fixed contact piece 68.
  • the contact spring 7 has as in Figure 1, two spring arms 9 and 10, each with are equipped with a contact piece 69 and one above the other a strand 70 are well electrically connected.
  • this relay is also constructed as in the previous ones Examples.
  • FIG. 7 shows another embodiment of the relay shown as a single changer.
  • it has a pedestal 71 an insulating wall 72 with three lying in a row Bags 73 (only two of which can be seen) for holding Connection elements 74, 75 and 76.
  • the connection elements 74 and 75 each form a counter-contact element 77 and 78, respectively the contact spring 7 with a spring arm 9 between the two Counter contact elements is switchable.
  • the two opposite Contact pieces 79 of the spring arm 9 are via a wire 80 connected to the connection elements 76.
