Definitions

  • the invention relates to a switching bridge for electrical switching devices, in particular for contactors, with a number of contact bridges which are arranged next to and / or one above the other in windows and which carry contact pieces at their ends and which are each under the pressure of a contact spring.
  • Switching bridges of the aforementioned type are known in a wide variety of embodiments, for example from DE-A-1 909 460. What these switching bridges have in common, however, is that all the contact springs are designed as spiral springs and are inserted into the respective windows in such a way that they are either on the one hand Support the top or bottom wall of the window and on the other hand on the relevant contact bridge.
  • This construction has the disadvantage that only manual manufacture of the switching bridge is possible, that is to say that each contact bridge with the associated spiral-shaped contact spring must be inserted into the relevant window by hand.
  • Another disadvantage is that the spiral spring only presses in the middle on the contact bridge in question and cannot cause the contact bridge to be held.
  • each contact back seen in its longitudinal direction, must be provided with projections or other guide pieces on both sides, which usually grip around the edges of the window and in this way keep the contact bridge immovable in its longitudinal direction.
  • projections or other guide pieces on both sides, which usually grip around the edges of the window and in this way keep the contact bridge immovable in its longitudinal direction.
  • the invention has for its object to provide a switching bridge, which allows automatic production, that is, equipping with contact bridges, and in which abrasion is practically avoided, so that a high level of contact reliability is ensured.
  • each contact bridge is bent through 90 ° upwards and in that central projections are provided on the upper end faces of these ends, which engage in correspondingly shaped holes near the ends of the contact spring designed as a leaf spring.
  • An advantageous embodiment of the invention is achieved in that semicircular recesses are provided in the central region of the two longitudinal edges of the contact spring are in which appropriately shaped projections engage in the window.
  • each contact bridge can be grasped mechanically together with the leaf spring lying thereon. With a slight compression of the leaf spring, it can then be easily pushed into the window with the contact bridge, without tilting or the like being necessary. When the leaf spring is released, the projections engage in the semicircular recesses of the contact spring, so that the contact spring and the contact bridge are held securely at the same time.
  • Figures 1 and 2 show a partial section of a switching bridge 1 with a transverse window 2.
  • the switching bridge can have any number of windows one above the other and / or next to each other, so that the construction described below is repeated accordingly often for each window.
  • recesses 3 and 4 are provided on both sides of the window, so that the actual window 2 is incorporated in the web 5.
  • the illustrated embodiment of the switching bridge is particularly characterized by the secure mounting of the Contact bridge 55 off.
  • the ends 56 and 57 of the contact bridge 55 are bent upward by approximately 90 °.
  • Central projections 58 and 59 are provided on the upper end faces of these ends, which engage in correspondingly shaped holes 80 which engage near the ends of a contact spring 62.
  • the contact spring 62 is designed as a leaf spring bent convexly with respect to the associated contact bridge 55 located underneath.
  • Contact pieces 60 and 61 are attached to the underside of the contact bridge 55.
  • semicircular recesses 63 and 64 are provided, into which correspondingly shaped and arranged projections 65 and 66 projecting into the window 2 engage.
  • an automatic assembly is possible by simply inserting the contact bridge with the contact spring.
