Definitions

  • a disadvantage of the known switch is that the movable Spring tongues only after the casting of the actuator be attached to the actuator.
  • Another disadvantage of the known switch is that through the grinding movement the moving contact surfaces both in contact with the embedding the fixed contacts Insulating compound as well as with the fixed contacts get yourself. Furthermore, the transition to contacting or separation of a fixed contact the contact surface comparatively between moving and stationary contact changed more slowly while at the same time Part of the moving contact in connection with the stationary contact surrounding insulating compound. Through it The arc formed in this way becomes the surrounding insulating material warmed and possible contact contamination formed by the insulating compound are burned onto the moving contact.
  • the object of the invention is the switching behavior of a Improve switch of the type mentioned above, so that both load currents and possibly control currents through this Switches can be switched.
  • the invention therefore consists in, on the one hand, the Connect spring tongues to each other with a plastic frame and also the plastic frame in the switch housing anchored in place. This will be a pushing Movement parallel to the contact level of the fixed contacts locked out.
  • the change in contact between fixed and mobile contacts happen rather with With the help of a mechanical control by a suitable Actuator is driven. That way it is possible a transition of the moving contacts from fixed Contacts to those surrounding the fixed contacts Avoid insulating material, so that contamination of the Avoiding contacts and a clean separation of the contacts from each other during the switching process.
  • the switch housing It is also possible to mold the switch housing to simplify, because the plastic frame with the spring tongues and the housing itself is manufactured in separate casting processes become.
  • the structure of the switch according to the invention still allows contact to be made with the moving contacts before anchoring the plastic frame in the switch housing to be checked step by step, as explained below becomes.
  • the moving contacts contact the Contact tongues due to the movement of an actuator the stationary in a suitable switching sequence. By modification the control curve is therefore possible, even with the same course of movement of the actuator to change the switching sequence.
  • the present invention is particularly suitable for actuation the moving contacts by means of an operating lever a steering column switch according to the combination of features according to claim 4.
  • the operating lever By the movement of the operating lever so act the assigned to the individual spring tongues Control cams on the spring tongues and create so one depending on the position of the operating lever given contact. Should the order of Contacting depending on the given positions the actuating lever can be changed, it is recommended in Further development of the invention, the combination of features Claim 5. After that, it is only necessary to choose the appropriate one Control curves to select one from the position of the operating lever to achieve the desired switching sequence.
  • the resulting structure essentially has the appearance a comb, with the plunger at the ends of the comb teeth protrude perpendicular to the ridge plane. Because the switch housing to be equipped with these combs by machines, must be prevented that the comb teeth in the transport container interlock with each other. For this are on the comb teeth corresponding combinations of features according to claim 7 computational approaches, which are in the level of Comb and so the spaces between the comb teeth to complete. In this way, prongs get caught impossible that belong to different combs.
  • Fig. 1 the contact tongues 1,2,3 are shown, which the resilient ends of the movable contacts 4,5,6.
  • the contact tongues are made from a common contact plate 7 punched out and through a plastic socket 8 together connected. The procedure is such that before the extrusion coating the plastic socket 8 the contact tongues over webs are interconnected so that they are easily in the desired Allow layer to be placed in the mold. After this The undesired electrical connections are encapsulated creating connecting bridges.
  • contact lugs 9 to 11 are also formed at the same time, which after injection molding with the plastic socket 8 to plug connections 12,13,14 are folded.
  • Lines indicated within the plastic socket 8 is the Contact tongue 1 with the two plug connections 12, 13 and two spring tongues 2 and 3 with the plug connector 14 electrically connected.
  • 3 shows a side view of FIG. 1.
  • FIG. 4 is the area of the connecting lugs 15 in FIG. 1 kinked perpendicular to the viewer plane and at the same time the plug connections 12 to 14 are folded according to FIG. 2.
  • a locking bar 16 is indicated, through which the plastic socket 8 with the switch housing can be locked.
  • Fig. 7 is still the spring tongue 1 with the movable contact 4 can be seen in an enlarged view, the movable contact 4 is opposite a fixed contact 17, which is locked on the switch housing.
  • Fig. 9 shown position of the contact tongue, in which the Locking bar 16 in a corresponding recess 18 in the switch housing is engaged, the movable contact 4 on the fixed contact 17 so that these two contacts connected to each other in the basic position of the switch are.
  • the plunger 20 is in one Through opening 23 of a wall of a switch housing 22 guided.
  • the tappet is controlled by a control curve 24 driven, which is perpendicular to the direction of movement of the Ram moved in the direction of the double arrow F past the ram 20.
  • the cam carrier 25 is by the end of a Actuating lever 26 (see Fig. 5) in the direction of the double arrow (F) as shown in FIG. 6 taken by the operating lever 26 around the bearing pin 27 within a driver 28 is tilted in the switch housing of the steering column switch. This tilting movement turns the cam carrier 25 in Moved in the direction of the double arrow F and thus the control curve 24 on the plunger 20 in the intended switching positions brought.
  • the driver 28 is in turn via a bearing bore 29 and a bearing pin 30 pivotable about the axis A, but with the end of the operating lever 26 in the cam carrier 25 is freely movable in the pivoting movement.
  • the attachment is important for the switch according to the invention the plunger, of which the switch described here three are provided, but of which in FIGS. 7 to 9 only the two plungers 20 and 29 can be seen.
  • the three Tappets 20, 29 are each provided with a spring arm 31 common cross member 32 connected, the cross member 32nd with the three spring arms 31 essentially like a comb looks three prongs, and being from the ridge plane to the individual spring arms (tines) located plunger 20.29 protrude vertically.
  • the plunger is through the in the housing wall guided cam carrier 25 by means of it Control cams 24 driven (see Fig. 6 and 7), wherein in Fig. 7 of the cam carrier 25 perpendicular to the viewer plane is guided in the direction of the double arrow F.
  • the locking bar 16 is shown in FIG. 9 in a corresponding locking groove snapped into place, causing it to moves a predetermined path that leads to a corresponding one Biasing of the movable contacts 4 against the stationary contacts 17 leads. Because here the plug connections 12, 13 in the corresponding passage openings of the Switch housing are held, the spring tongues 1 to 3 bent accordingly, so that you already have one small shift of the locking bar to a significant Spring preload can reach.
  • the main advantage of Invention is that through it one in one plane running (pushing) movement of the actuator in a vertical movement of the contacts to each other implemented is, so that dirt and material wear largely avoided.
  • the switch is still on easy to equip and test automatically.
  • the complexity the mold for the switch housing is made by the invention reduced.
