Definitions

  • the invention relates to a switching device with two contact elements penetrating a base plate at a certain distance from one another, which form connection elements on one side of the base plate and are formed on the other side of the base plate to form a fixed contact and to form a switching arm bridging the distance between the contact elements. and in which the spring action of the switching arm is directed away from the base plate and against an end section of the fixed contact.
  • Such a switching device is known from DE 28 16 776 C2. It can be easily inserted into grid holes in a printed circuit board and soldered there, so that current paths guided via the switching device can be opened or closed.
  • the object of the present invention is to develop a switching device of the type mentioned at the outset in such a way that the contact reliability of the connection between the switching arm and the fixed contact is further improved.
  • this object is achieved in that the free end of the switching arm consists of a flat piece provided transversely to the end section of the fixed contact, which is V-shaped into two V-legs delimiting a V-notch, and that the flat piece with its V -Notch is aligned with the end section of the fixed contact parallel to the base plate.
  • the flat V-structure at the end of the switching arm can be easily created, for example, by a punching process.
  • These V-structure at the free end of the switching arm also advantageously enables a double contact between switching arm and fixed contact to be designed to be particularly reliable, since each V-leg of the V-structure only touches the fixed contact in a very narrow area, resulting in a double contact with a relatively high contact force results.
  • This design of the switching device also results in a separation between the switching arm and the fixed contact only in that the switching arm is moved against the base plate. The switching arm does not have to be deflected laterally. The anchoring of the switching arm in the base plate is therefore not subjected to torsion.
  • the band-shaped end section of the fixed contact is provided with a flat side transverse to the V-shaped contour of the switching arm.
  • the fixed contact touches the V-legs almost linearly, namely with edges of its contour which is rectangular in cross section, as a result of which the contact connection between the fixed contact and the switching arm is further improved.
  • an upper housing part covering the switching arm is slidably mounted on the base plate supplemented to a lower housing part between a first and a second position, that the upper housing part is directed towards the switching arm and is attached to it in the Has first projection of the upper housing part supporting projection and that the switching arm is provided with a bend in the second position of the upper housing part with release of the switching arm directed against the base plate.
  • the switching arm must therefore not be touched by hand to disconnect the connection between the switching arm and the fixed contact, which prevents circuit parts from being endangered by a discharge of electrostatic potentials.
  • a base plate 1 which consists of an insulating plastic and which has an elongated strip-shaped design, is penetrated by a contact element 3 in the vicinity of its narrow sides 4.
  • the contact elements 3 made of strip or strip-shaped material are angled on one side 5 of the base plate 1 with their ends parallel to the base plate 1 to form connection elements 2 and form contact surfaces 6 with flat sides with which the switching device can be placed on metallized areas of a printed circuit board.
  • the base plate 1 is provided on the side 5 with recesses 7, so that the contact surfaces 6 hardly protrude beyond the side 5 of the base plate 1 because the connection elements are located within the recesses.
  • each narrow side 4 on the side 5 of the base plate 1 is assigned two connection elements 2, each connection element 2 being seated in a corner region of the switching device.
  • the four connection elements 2 on the side 5 of the reason plate 1 either result from a branching of each contact element 3 on each narrow side 4 of the switching device, which can be easily produced, for example, by appropriately punching out the contact elements 3 from a flat material, or a respective connecting element 2 is independent of the adjacent contact element 3 in the base plate 1 anchored.
  • the four contact surfaces 6 thus obtained, which are assigned to the corner points of the switching device on the side 5 of the base plate 1, make it possible to attach the switching device in a particularly stable manner via four soldering points.
  • the corresponding contact element 3 is angled at a certain distance from the base plate 1 parallel to the base plate 1 and in the direction of the switching arm 10, so that an end portion 11 of the fixed contact runs parallel to the base plate 1 and points to the switching arm 10.
  • the other contact element 3 is angled to form the switching arm 10 in the direction of the fixed contact 9 and dimensioned so long that the free end 12 of the switching arm 10 extends below the end portion 11 of the fixed contact 9.
  • the free end 12 of the switching arm 10 consisting of a flat sheet metal section is angled away from the base plate 1 against the end section 11 of the fixed contact 9 and preferably divided into two V-legs 13 by a punching process in a V-shape (FIG. 2).
  • the V-notch thus formed receives the end section 11 of the fixed contact 9 between its V-legs 13 when the switching arm 10 springs out against the end section 11 of the fixed contact 9.
  • both the contact element 3, which forms the switching arm 10, and the contact element 3, from which the fixed contact 9 is made, are made of band-shaped material and the end section 11 of the fixed contact 9 is aligned with a flat side on the V-contour of the switching arm 10, the end section 11 touches the switching arm 10 with edges 14 (FIG. 2) of its rectangular cross-section in the region of the V-legs 13, if by corresponding coordination of the V-contour and the dimensions of the end section 11 ensure that the end section 11 is intercepted by the V-legs of the V-contour.
  • Switch arm and fixed contact are covered by an upper housing part 15 which is slidably mounted on the base plate 1 which is supplemented by side walls 16 to form a lower housing part 17.
  • the upper housing part 15 is fixed to the lower housing part 17 by means of an elastically bendable side wall section 18, which engages around a guide edge 20 of the lower housing part 17 with a latching hook 19 at the end.
  • the side wall section 18 is dimensioned so narrow that it can be moved back and forth between end positions in a recess 21 in a side wall 16 of the lower housing part 17 parallel to the longitudinal extent of the switching device. A first and a second position of the upper housing part relative to the lower housing part is thereby determined.
  • the upper housing part 15 has on its inside a projection 22 which projects so far against the switching arm 10 that in the first position of the upper housing part the switching arm 10 is pressed by the projection 22 against the base plate 1 and thereby released with its free end 12 from the fixed contact 9 becomes. It is sufficient to move the switching arm 10 only so slightly that the electrical contact between the switching arm 10 and the fixed contact 9 is interrupted.
  • the upper part 15 In the first position of the upper housing part 15, the upper part 15 is aligned with the lower part 17, so that, for example, an automatic placement machine can easily detect the switching device.
  • the contact connection between switching arm 10 and fixed contact 9 is interrupted, so that when switching on the Wennvor direction to a printed circuit board no unwanted soldering of the tinned points of contact of the switching arm and fixed contact can take place.
  • the projection 22 faces a bend 23 of the switching arm 10 directed against the base plate 1.
  • the projection 22 can therefore not act on the switching arm 10 in the second position of the upper housing part 15.
  • the switching arm 10 therefore contacts the end section of the fixed contact 9 with its V contour.
  • the deflection 23 of the switching arm 10 is limited on the one hand by the free end 12 of the switching arm directed against the end section 11 of the fixed contact 9, and on the other hand by a branch 24 of the switching arm directed obliquely against the base plate 1.
  • the branch 24 forms a sliding surface for the projection 22 when the upper housing part 15 is moved from the second to the first position.
  • a side surface 25 of the projection 22 directed against this branch 24 is chamfered to improve the interaction between the switching arm and the projection.
