Definitions

  • the invention relates to the manufacture of a switching device with at least one fixed contact part and at least one contact arm part and an interposed insulating part, the fixed contact part and the contact arm part being punched out of electrically conductive strip material and provided with fastening breakthroughs and separated from the strip material after mutual alignment and connection to the insulating part are, the tapes are also moved to each other in cycles.
  • a method has become known from DE-AS 12 91 833.
  • the relatively small insulating part is individually assigned to a metallic carrier part and connected to it in a complex operation.
  • connection point formed by a mandrel It is difficult to simultaneously insert the four tabs of each connection point formed by a mandrel into their associated opening of the insulating part, although it should also be noted that four such connection points are created at the same time.
  • the subsequent attachment of the contact springs is carried out in the same complex, difficult and incorrect connection-prone manner. The latter arise when only three of the four wedge-shaped tabs reach through the hole and one is clamped between the parts.
  • DE-AS 1081 954 also shows the arrangement of two electrically conductive contact springs on both sides of an insulating layer.
  • the use of swelling pimples is proposed on the one hand, and the encapsulation with a thermoplastic layer on the other hand.
  • the insertion of the pipules into the punch holes and the subsequent swelling are expensive operations.
  • DE-AS 10 67 504 describes the connection of a metallic support with a metallic housing part, from which a rivet shaft is pressed out.
  • the latter is dimensioned in such a way that it can easily be inserted through an opening in the metallic carrier with a molded-on contact piece, the cross-sectional shapes not necessarily having to be the same.
  • the connection element - here the rivet shank - must be manufactured in a work step upstream of the plugging together.
  • caulking is necessary.
  • the object of the invention is therefore to develop the method of the type mentioned in such a way that the switching devices can be produced in a simple, cost-saving manner.
  • the insulating part can be handled much more easily, but nevertheless more precisely and faster than in the known prior art, for example according to DE -AS 12 91 833.
  • preforming fasteners on one of the parts of the switching device is unnecessary.
  • simply by pushing material parts of the insulating part into openings in the respectively assigned contact arm part or fixed contact part a problem-free and fast and permanent connection is achieved will create.
  • the breakthroughs in the metal parts of the switching device are therefore used in two ways.
  • the protuberances be pushed beyond the opening and the protruding end of the protuberance is pressed broadly. This increases the security of the connection and leads to an even more robust switching device. In addition, this allows the use of particularly thin sheets, in the sheet level of which the anchoring alone would not be sufficiently guaranteed.
  • the protuberances comparable to "rivet heads improve the anchoring there considerably.
  • a further embodiment of the method is characterized in that the insulating part is only removed after the wide pressing.
  • the parts to be connected to one another are correctly assigned to one another during the spreading operation.
  • Both parts are, at least up to the finished formation of the protuberances, still connected to their strip material, which can be safely aligned in a known manner by means of a perforation and transported in cycles. Therefore, the method according to the invention is also particularly suitable for mass production, in which, in a known manner, the saving of fractions of a penny is also important, because such penny fractions can also add up to a quite considerable amount.
  • a further method step advantageously consists in that the completed switching device is separated from the supporting band of the contact arm part and is thus available for further use, in particular for installation in a keyboard or the like.
  • a preferred embodiment of the invention provides that the bands of the insulating part and the fixed contact part are shifted clockwise parallel to one another and perpendicular to the band of the contact arm part, the fixed contact part being fastened on one side and the contact arm part on the other flat side of the insulating part, as is the principle according to is known.
  • Another development of the invention is characterized in that the contact arm part and the fixed contact part are connected to the insulating part at the same time.
  • this requires a corresponding arrangement of the tapes with the three parts and a design of the switching device parts adapted to this process step.
  • the drawing shows schematically both the switching device and the various steps in the manufacturing process of this switching device.
  • the switching devices are expediently produced using three flat bands, band 1 and band 2 being made of electrically conductive material, while band 3 being made of electrically non-conductive material, in particular a thermoplastic material.
  • band 1 and band 2 being made of electrically conductive material
  • band 3 being made of electrically non-conductive material, in particular a thermoplastic material.
  • the bands 2 and 3 run parallel to one another in the same or slightly. about levels of material offset in height, while the band 1 runs transversely, preferably perpendicularly, to the two bands 2 and 3.
  • the belts 2 and 3 run over the belt 1.
  • the directions of advance of the belts 1, 2 and 3 are symbolized by arrows 4, 5 and 6. The feed movement is gradual, as will be explained in more detail below.
  • the contact arm parts 7, the fixed contact parts 8 from the band 2 and the insulating parts 9 are punched out from the band 1. However, all parts initially remain connected to a remaining strip 10 or 11 or 12, in particular a side strip, of the strip via at least one bridge and are only separated therefrom at the predetermined point in time.
  • the contact arm part 7 has a contact arm 13 with a movable contact 14 and one which extends in the opposite direction Connection element 15 has.
  • the movable contact is formed by the feathered free end of the contact arm 13.
  • Special contact rivets are not provided in the exemplary embodiment.
  • two fastening openings 16 and 17 have been punched in one or in a second operation.
  • the slightly larger opening 18 is used for transporting the belt 1.
  • Corresponding openings 19 and 20 are provided on the belts 2 and 3.
  • the insulating part 7 has an essentially rectangular opening 35 to which the contact arm 13 and a fixed contact 21 on the fixed contact part 8 are assigned in the finished switching device.
  • This fixed contact is a laterally projecting tab of the fixed contact part 8, which, like the contact arm part 7, has an electrical connection element 22.
  • two fastening openings 23 and 24 are also present on the fixed contact part 8.
  • a contact arm part 7 is assigned to an insulating part 9, the infeed being carried out in the direction of arrow 4 or 6.
  • these two parts are superimposed as shown in FIG. 5.
  • the material of the insulating part 9 is now pressed down at the points of the fastening openings 16 and 17 perpendicular to the image plane.
  • the deformation is plastic, i. H. the pressed-out material parts of the insulating 9 remain in the form of bulges 26, 27 or protuberances in the two fastening openings 16 and 17.
  • they protrude downwards beyond these fastening openings, so that the projecting free ends are then moved in the opposite direction by means of a can press further tool, which at least creates an approach that is comparable to a rivet head.
  • the insulating part 9 is separated along the dash-dotted line 25 (FIG. 5).
  • this unit consisting of a fixed contact part and an insulating part, is transported further in the direction of arrow 4.
  • a fixed contact part 8 is brought over this unit.
  • material parts are pressed out of the insulating part through the fastening openings 23 and 24.
  • the protruding ends of these expressions 28 and 29 are also flattened out, in particular with simultaneous thorning, which is symbolized by the circles 30 and 31.
  • An immediate detachment from the remaining tire 10 or the retaining tab 32 is not provided, but is further transported, in the direction of arrow 4, with the next feed step of the tape 1. This is, however, a special feature of the exemplary embodiment, which is not absolutely necessary. Where and when to carry out the separation depends on the possibilities of the tool design and also the further use of the switching devices.
  • the retaining tab 32 of the band 1 corresponding retaining tab of the bands 2 and 3 are designated 33 and 34, respectively. While the retaining tabs 32 and 34 are relatively wide, the retaining tab 33 of the contact part 8 tapers towards it very sharply.
