Definitions

  • the invention relates to a relay, in particular for automotive technology, with the features of the preamble of the claim 1.
  • relays adversely affect the achievable price-performance ratio out.
  • implementation of relays with several switch contacts that can be actuated by a coil is associated with great effort in this technology.
  • circuit board in the usual way, including of the relay parts or the relay can be automatically equipped can.
  • the previously common flying wiring of the individual Components or contacts are through the conductor tracks of the circuit board replaced.
  • a relay comes closest to the state of the art stackable contact set carriers (DE-A-2 462 299).
  • the Actuating force of the only anchor is one Transfer contact actuation slider to the next. This results in a high space requirement a considerable construction effort
  • the invention lies Task, a relay, especially for KZF technology, to create, which has a low space requirement, a simple structure and with little effort for different numbers of switching contacts is changeable.
  • the Contact spring is provided on a stationary support part and by means of a connecting part with the anchor and one with the Armature coupled contact spring at least one further switching contact connected, there is the advantage that initially all Elements of a switching contact, namely at least one fixed Contact and a contact spring detached from the coil unit, in particular the armature of the coil unit, are mountable.
  • the design to the number of required Switch contacts are made in a simple manner in that only the desired number of switching contacts for this suitable positions and the contact springs of all Switch contacts by means of at least one connecting part be connected to the armature of the coil unit.
  • Connection part for this consist of non-conductive material.
  • the connector is detachable and / or pluggable, whereby very simple assembly of the relay results.
  • the first contact unit is made in one piece, and the fixed contact and the Contact spring provided on the stationary support part are by means of a part made of non-conductive material.
  • the Such a contact unit is preferably produced by partially overmolding or potting the electrically conductive Contact parts. This gives the advantage of a further simplified assembly of the relay according to the invention.
  • the Invention uses a coil unit in which a pin non-conductive material is guided axially, wherein the pin ends or related parts the anchor and the Contact spring on the opposite side of the armature Actuate the switch contact provided for the coil unit.
  • the coil unit and at least one contact unit on a common base plate arranged, which in a known manner as a printed Printed circuit board for contacting the coil unit and the at least one switching contact can be formed.
  • Fig. 1 shows a relay 1 according to the invention, which consists of a Coil unit 3 exists, which together with a connector assembly 5 formed on a printed circuit board 7 Carrier part is mounted.
  • the coil unit 3 consists of a coil former 9 made of electrical insulating material used to hold the actual Relay coil is used and a ferromagnetic in the coil axis Has coil core 13, and from a right-angled Yoke 11 made of ferromagnetic material, in one Leg of the bobbin 9 fixed with its coil core 13 is.
  • the coil unit 3 has an armature 15 which in a recess 17 at the end of the parallel to the coil axis Leg of the yoke 11 is mounted tiltable.
  • the armature 15 projects with a partial area 15a over the leg of the yoke 11, a prestressed portion 15a Tension spring 19 attacks, the other end of a fastening arm 21 is fixed in the knee of the yoke 11.
  • a contact spring 23 is arranged on the armature 15, at the end thereof a cylindrical contact point or contact rivet 25 is provided is.
  • the contact spring 23 In the rest position of the coil unit 3, i.e. for non-current-carrying Coil, the contact spring 23 is supported and thus the armature 15 on a stop 27 of a first contact unit 29 from.
  • the contact unit 29 can, as in that in the drawing illustrated embodiment of the invention, a single Have contact 31, which together with the stop 27 in one piece is formed with the bobbin 9.
  • the switching contact designed as a contact unit 29 can of course in addition to the arrangement shown as NO contacts can also be designed as NC contacts or change-over contacts.
  • the armature 15 is connected by means of a strand 33, the other of which End inserted into a hole or recess in the circuit board 7 and on the back of the circuit board 7 with one of the Connection contacts 35 of the plug assembly 5 is connected.
  • the armature 15 and the contact spring 23 as current-carrying To serve elements, these must of course be electrical conductive material.
  • the plug assembly 5 which - as in FIG. 1 shown - essentially angled at right angles Has contacts 35, which in a plate 41 made of non-conductive Material are kept.
  • To manufacture the plug assembly 5 can in the usual way by punching and bending manufactured contacts made of sheet metal are used, wherein the plate 41 by overmolding or potting the relevant Parts of the contacts 35 can be made.
  • connection ends 35a releasing the end face of the plate 41 a right-angled Have recess 41a, so that the top of the conductor track parallel end face of the plate 41 as a stop and Abutment for the relevant PCB surface is used.
  • the other leg of the recess 41a serves in addition to this purpose furthermore as a stop for the end face of the printed circuit board 7 and additionally facilitates the insertion of the terminal ends 35a into the corresponding holes in the printed circuit board 7.
  • the first contact unit 29, the printed circuit board 7 and the connector assembly 5 has the relay shown in Figures 1 and 2 according to the Invention another, designed as a contact unit 43 Switch contact, which is shown in perspective in Fig. 3 is.
  • the contact unit 43 consists of a fixed contact 45 with a contact point or rivet 47, which with a another contact rivet 49 cooperates with a contact spring 51.
  • the switch contact 43 is again trained as a closer.
  • the contact spring 51 is arranged on a stationary support part 53 and can with this in a known manner by means of a Rivets 55 may be connected. To adjust the spring characteristics the contact spring 51 can also by means of another Tuning rivets 57 at a predetermined position with the support member 53 connected.
  • the contact 45 and the fixed support member 53 can - as shown - Shaped or angled, this by the Injection molding of partial areas connected to form a one-piece unit are.
  • the connecting part, preferably produced by injection molding 59 can have an arm 59a, which in the Assembly of the contact unit 43, the bobbin 9 or the first Contact unit 29 includes in a partial area. In this way there is an exact distance of the contact spring 51 from the Contact spring 23 or the armature 15.
  • the contact spring 51 the further switching contact 43 with the contact spring 23 and thus with the armature 15 of the "basic relay" by means of a preferably made of plastic connecting part 61 connected.
  • the Connecting part 61 can - as shown in Figures 1 and 3 - Have slots 61a and 61b in which the contact springs 23 and 51 are included.
  • the contact spring 23 - as can be seen in FIG. 4 - have an arm 23a, so that not the actual contact spring 23, but the arm 23a by means of the connecting part 61 connected to the contact spring 51 of the further switching contact becomes. Since the arm 23a with an additional rivet 23b the anchor 15 is connected, there is the advantage that because the resulting complete decoupling of the arm 23a from the actual contact spring the switching process of the first Switch contact 29 not by coupling the armature or the contact spring 23 is influenced by the further contact spring 51 becomes.
  • the core 13 of the relay coil is included an axial bore 63 in which a pin 65 from preferably non-conductive material guided axially is.
  • the pin 65 acts on one end of the armature 15 and at its other end the contact spring 51 one on the armature 15 opposite side of the coil unit arranged contact unit 43.
  • the contact unit 43 can, except for minor Deviations in the design of the connecting part 59 accordingly the representation according to FIG. 3. To this The switching movement of the armature 15 can be very simple Actuation of one on the opposite side of the coil unit 3 arranged switching contact can be transmitted.
  • FIG. 5 also at least one additional contact unit on the anchor side 43 may be provided, which according to that in FIGS. 1 and 2
  • the illustrated embodiment can also be actuated by the armature 15 is.
