Definitions

  • the invention relates to a U-shaped connecting device for the simultaneous actuation of the switching toggles rotatable about an axis of rotation of at least two strings in line.
  • a U-shaped connecting device of the type mentioned is known from DE-AS 25 32 192. With this device, the switch toggle of several switches to form z.
  • B. a multi-pole switching device connected to each other. It is formed from stamped and U-shaped sheet metal and has notches on the inner walls of the legs, which engage in corresponding recesses on the shift knob. As a result, the device can be pushed in one direction onto the switching toggles lying in a row; To prevent pulling against the direction of assembly, a tongue is provided on the web of the U-shape, which in the assembled state against the adjacent end face of the adjacent control knob is bent.
  • the bending of the tongue entails a risk of breakage, since the sheet metal has to be bent with a relatively high force by means of a punching or bending tool on the assembled switching device.
  • the actuating surface for actuating the switch toggle is only increased by the amount of the sheet thickness, about 0.5 mm, compared to the switch toggle height, so that handling is relatively difficult.
  • the object of the invention is to provide a U-shaped connecting device of the type mentioned, which is easier to assemble and avoid the risk of breakage and in which the actuating area can be increased in a simple manner.
  • the connecting device according to the invention is made of plastic. This makes it possible to provide a nose formed on the inside of the U-shape instead of a flap to be bent as a means of preventing pulling off in the direction opposite to the assembly direction, which nose slides over the adjacent shift knob during assembly and is locked behind the shift knob in the assembled state .
  • the connecting device can thus not be pulled off either in the direction of the axes of rotation of the shift knobs or in the direction of the shift knobs perpendicular to their axes of rotation.
  • a displacement of the connecting device in one direction is prevented by the interaction of the formations on the switching knob and the formations on the inner surfaces of the U-shaped connecting device, these also preventing pulling off perpendicular to the axes of rotation; peeling in the opposite direction is prevented by the nose.
  • An advantageous embodiment of the invention can be such that the connecting device has an area of greater height in its central area for reinforcement and better manageability.
  • the outer surface of the web of the U-shape has a centrally arranged, approximately roof-shaped attachment.
  • the nose is expediently molded onto the inner surface of the web. It is formed in that a tongue is provided in the web, formed by a support extending from the free end of the device, on which the nose is molded.
  • FIG. 5 Two line circuit breakers 10 and 11 are lined up next to one another in a view of the narrow sides. From a recess 12 and 13, pivoting toggles 16 and 17 protrude about axes of rotation 14 and 15, of which the toggle 16 of the switch 10 is completely visible and the toggle 17 of the switch 11 is only partially visible. The axes of rotation 14 and 15 of the two switching knobs are aligned with one another.
  • Each switching knob 16, 17 has on its side surfaces running parallel to the axes of rotation 14 and 15 - in the switching knob 16 only the side surface 18 is visible - depressions 19 and 20; the recess 20 is not visible. These recesses 19 and 20 run parallel to the axes of rotation 14 and 15 and only cover half the area of the side surface 18, so that they open into the same end surface 21 and 22 of each switching knob 16, 17.
  • the depressions 19 and 20 can, as indicated above, be arranged on both side surfaces of the switching knobs 16 and 17; they can of course also be located on only one side, for example the side surface 18 of the switching knobs 16 and 17 facing the viewer. In the switches 10 and 11 shown in FIG. 5, the depressions 19 and 20 are provided on both side surfaces of the switching knobs 16, 17.
  • the two switching knobs 16 and 17 are covered by a connecting device 23, which will be described in more detail with reference to FIGS. 1 to 4.
  • the connecting device 23 has a U-shape with a web 24 and two legs 25, 26 formed thereon, which form an acute angle with one another, which is open in the direction of the open side of the U-shape.
  • the web 24 has an attachment 27 approximately in the middle of the connecting device 23, which forms a roof shape and which serves to increase the height H of the connecting device 23. The increased height is denoted by H1.
  • the web 24 has two parallel slots 28 and 29, which take a tongue 30 between them, on the inner end facing the U-shape a latch 35 shown in broken lines in FIG. 1 is molded.
  • the slots 28 and 29 are so on the web 24 that they connect directly to the inside of the legs 25 and 26.
  • each projecting perpendicularly to the leg surface and dimensioned in this way are that they fit into the recesses 19 and 20.
  • the nose 34 fits exactly into the depression 20, the nose 34 being able to come to a stop on the end wall 20a of the depression 20 which is located approximately in the middle.
  • a corresponding end wall also has the recess 19; it is designated by the reference number 19a.
  • the two switching knobs 16 and 17 are placed in alignment with one another, for example in the on or off position. Then the connecting device 23 is pushed perpendicular to the axes of rotation 14, 15 over the switching knob 16 and 17 so that the lugs 31, 32; 33, 34 come to rest in front of the recesses 19 and 20. There is the possibility that the locking lug 35 rests on the front edge of the shift knob, the tongue 30 being deformed.
  • the connecting device 23 is moved to the left, in the direction of arrow P, so that the lugs 31, 32; 33, 34 engage in the respective recesses 19, 20, namely until the lugs 31, 32 and 33, 34 come to abut against the end faces 19a and 20a of the recesses 19 and 20. If this is the case, the nose 32 will grip behind the left end face 21a of the switching knob 16 and in this way latch behind it, so that the connecting device 23 can no longer be pulled off the switching knobs 16, 17 in the opposite direction of the arrow P.
  • the end faces 19a and 20a prevent further displacement of the connecting devices in the direction of arrow P and that the lugs 31 to 34 engage in the recesses 19 and 20, also prevents the connecting device 23 from being pulled off in the direction of the switching knobs 16, 17, arrow direction P 1 .
  • Openings 40, 41 and 42, 43 can be seen in FIGS. 4 and 2, respectively, which are located exactly above the lugs 31 to 34. These webs have only tool-technical reasons. Of course, they also contribute to a certain saving in material.
  • the middle approach or attachment 27 serves both to enlarge the actuating area and to increase the rigidity of the connecting device 23.
  • FIGS. 1 to 5 show a connecting device 23, with which only two switching knobs 16 and 17 of two line circuit breakers 10, 11 are juxtaposed, so that a two-pole line circuit breaker is thereby formed. It is of course possible to design the connection device so that three or four adjacent circuit breakers can be connected to each other; For this purpose, three or four pairs of noses are provided, which correspond to the noses 31/32, 33/34 ... This only makes the connecting device longer.
  • the invention can also be applied to all other switching devices which each have a switching knob and are lined up in a row to form a multipole.
  • the invention is also realized if protruding lugs are provided on the side surfaces of the switching toggles and recesses adapted to the lugs are provided on the inner surfaces of the legs of the connecting device.
