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 coil 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 on both sides or other guide pieces, which usually grip around the edges of the window and in this way keep the contact bridge immovable in its longitudinal direction.
  • a cam switch in which the switching bridges each have a flat contact carrier with a rectangular cross-section, to which the movable contacts are attached.
  • the contact carrier is bent upwards at the ends by 90 o and provided with guide slots for receiving a leaf spring.
  • a coil spring is mounted between the contact carrier and a fixed switch part. Above the leaf spring there is an oval, rotatably mounted switching cam that presses on the leaf spring at a quarter turn and switches the switching bridge on against the force of the coil spring. After a further quarter of a turn, the switching cam lifts off the leaf spring again, so that the coil spring causes the switching unit in question to be switched off again.
  • the switching cam not only generates pressure forces on the switching bridge in the direction of the on and off movement during rotation, but also additional force components in the longitudinal direction of the switching bridge, it must be guided. This is done by attaching two guide pins to the movable contact carrier are, which slide in the guide holes of a solid, designed as an insulating body. On the one hand, this means a substantial increase in the mass to be moved when shifting, as well as friction, wear and tear and thus abrasion.
  • the contact rocker represents a switching bridge, which consists of a contact bridge carrying contact pieces and a curved leaf spring, in the ends of which holes are provided, through which folded lugs engage, which on the other hand are formed on the ends of the contact bridge.
  • a bracket with a leg is provided, which has a hole into which a nose engages, which is attached to the apex of the curved leaf spring, so that it is secured against lateral displacement.
  • the invention is based on the object of creating a switching bridge which, on the one hand, permits automatic production, that is to say equipping with contact bridges, and in which the abrasion is practically avoided, so that a high level of contact reliability is ensured.
  • each contact spring is designed as a leaf spring bent to the associated contact bridge, that the contact spring has a locking point in the form of semicircular recesses on the two longitudinal edges in the central region, that the contact spring is convex as seen from the locking point is that the latching point interacts positively with the adjacent window wall in that projections shaped and arranged in accordance with the recesses engage into the recesses, and that the ends of the contact bridge are bent upwards by 90 o to the contact spring, so that further projections engage on the end faces of the bent ends of the contact bridge in correspondingly shaped holes near the ends of the contact spring, so that the contact bridge is held in the longitudinal direction by the contact spring and in the transverse direction by the side walls of 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. If the leaf spring is now 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 explained 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.
  • the ends 56 and 57 of the contact bridge 55 are bent over by 90 o towards the top.
  • 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.
