Definitions

  • the invention relates to an electrical switching device according to the preamble of claim 1.
  • a switching device with 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.
  • the object of the invention is to provide a switching device of the type mentioned at the outset with a U-shaped connecting device in which the connecting device is easier to assemble and avoid the risk of breakage and in which the actuating area can be increased in a simple manner.
  • 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.
  • 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 designated H 1 .
  • the web 24 has two parallel slots 28 and 29, which take a tongue 30 between them 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.
  • 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 the arrow P, and the fact that the lugs 31 to 34 engage in the recesses 19 and 20 also means that the connecting device 23 is pulled off in the direction of the switching knobs 16, 17, arrow direction P 1 , prevented.
  • 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 lined up next to one another, 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.

Claims (6)

  1. Appareil électrique de commutation avec au moins deux commutateurs (10, 11) disposés côte à côte, en ligne, dont les leviers d'actionnement (16, 17) pivotant autour d'un axe de rotation (14, 15) sont couplés à l'aide d'un dispositif de liaison (23) en forme de U à des fins d'actionnement simultané des leviers d'actionnement (16, 17), les ailes (25, 26) du dispositif de liaison (23) entourant de deux côtés les leviers d'actionnement à l'état monté, avec des saillies en forme de nez (31, 33; 32, 34) disposées sur les faces intérieures des ailes (25, 26), qui pénètrent dans des creux (19, 20) correspondants des faces latérales parallèles à l'axe de rotation (14, 15) des leviers d'actionnement (16, 17), couvrant partiellement les faces latérales dans la direction des axes de rotation (14, 15) et débouchant dans une face frontale des leviers d'actionnement (16, 17) perpendiculaire aux axes de rotation (14, 15), un montage du dispositif de liaison (23) n'étant possible qu'à partir d'un côté des appareils de commutation, dans la direction des axes de rotation (14, 15) et des moyens étant prévus pour empêcher le retrait dans la direction opposée à la direction de montage, caractérisé par le fait que le dispositif de liaison (23) est réalisé en matière plastique et qu'il est prévu, en tant que moyen, un nez d'encliquetage (35) sur face intérieure du profil en U à l'extrémité antérieure dans la direction de montage, de telle sorte qu' après mise en place les nez (31, 32, 33, 34) engagés dans les creux (19, 20) empêchent un démontage du dispositif de liaison (23) aussi bien dans la direction de montage que dans la direction des leviers d'actionnement (P1) et que le nez (35) empêche un retrait dans la direction opposée à la direction de montage.
