Definitions

  • the invention relates to an electrical switching device according to the preamble of the claims 1.
  • a switching device of the type mentioned in which a contact point by simple Movement of a switch knob is opened or closed, serves as the main switch for switching off a pipeline network; he can as a control, switch and the like. Application Find.
  • the object of the invention is an electrical switching device of the type mentioned to create, which is simple and whose rung is of short length and that comes with few items.
  • the invention is thus characterized in that the pivoting lever is rotatably mounted with one end in the adjoining the mounting plane lower portion of the switching device in a knife edge bearing that acts on the pivot lever in the region of the movable contact piece acting approximately parallel to the longitudinal extent of the pivot lever spring force, the presses the pivot lever in the cutting edge bearing, and that upon actuation of the switch knob of the pivot lever due to the spring force from a first stable position (switch-on) via a dead center in a second stable position (switch-off) and can be brought back.
  • the use of a cutting bearing causes a reduction of the components, because so that the storage and power supply of the movable contact can be realized in one.
  • Blade bearings are known as such, see, for. B. DE 436 388.
  • the arrangement or Assignment of the spring force, which is generated by a helical compression spring causes a kind of snap-action mechanism, in which the pivot lever from a first stable position (Switch-on) is spent on a dead center in a second stable position (Disconnected position). Due to the arrangement of the spring to the movable pivot lever is a high pressure force in the cutting edge bearing and also a high contact force generated.
  • the switching device 10 according to FIG. 1 has a shell-shaped housing lower part 11, in FIG the individual components of the switching device are housed. After installation of these components, the lower housing part is closed with a housing cover, which has a plate shape or the same shape as the housing base.
  • the peripheral contour of the switching device 10 is formed in a base construction, with a front front wall 12, two rear front walls 13 and 14, front narrow side surfaces 15 and 16 and rear narrow side surfaces 17 and 18, wherein the front and rear front surfaces approximately parallel to a mounting surface 19, while the narrow side surfaces 15, 16, 17, 18 are aligned perpendicular thereto.
  • a switch knob 20 is arranged, which is connected to a Rotary movement gestattenden Drehachsenstoff Kunststoff (in the following as centerpiece designated) 21 molded actuating handle 22 has.
  • This operating handle 22 protrudes from the front 12 out.
  • a slot 26 is provided which - in the installed state in closed position - Run approximately perpendicular to the mounting surface 19.
  • leg 28 of a leg spring 29 on At the switch interior indicative arcuate outer surface 27 of the leg 25 is a leg 28 of a leg spring 29 on; the other leg 30 is between a wall portion 31 and a pin 32 fixed substantially immovable; of the Leg 28 exerts a force on the operating handle which turns the control knob clockwise seeks to pivot, so that the leg 28 the switch knob 20 in the switch-on position is positioned.
  • the arch form or the arch surface 27 is designed such that that in the off position, when the leg 28 against the arc surface comes to the concern, the switch knob is not obstructed.
  • each Terminal screws 35 and 36 and a clamping body 37 and 38 have.
  • a terminal lug 39 fixedly connected, which is parallel to the Fixing plane or mounting surface 19 extending first leg 40, a to vertical web 41 and one perpendicular to the web 41 and parallel to Attachment surface or to the leg 40 extending second web 42 has.
  • the web 41 starting from the first leg 40, perpendicular to the mounting plane and oriented in the direction toward, and the inner surface of the fold between the web 41 and the second leg 42 forms a fixed abutment 43, in which the end 44 of a pivot lever 45 by means of a compression spring 46, here as Coil spring is formed, is pressed.
  • a contact carrier 47 is connected, which has a first Section 48, which runs parallel to the attachment surface or to the attachment plane 19, a second portion 49 which is at an acute angle to the mounting surface is angled towards this, and a third section 50, which is perpendicular extends to the mounting plane and extending in a direction perpendicular to the mounting plane Slot 51 engages to its fixation, has.
  • a fixed contact piece 52 At the angle to the mounting plane extending portion 49 is on the outer surface, i. the area of the pointing away from the mounting plane 19, fixed a fixed contact piece 52.
  • a movable contact piece 53 cooperates, which fastened in the vicinity of the free end of the pivot lever 45 at this is, on its side facing the mounting plane 19 side.
  • the free end of the pivot lever 45 engages in a cutout 56 in the coupling piece 55;
  • the cutout 56 is designed so that in a switching operation a mutual Obstruction of the pivot lever 45 and the coupling piece 55 avoided is.
  • On the coupling piece 55 includes an arm 57, in which a leg of a U-shaped bracket 58 engages; the other leg of the U-shaped bracket 58 engages a slot on the switch knob 20 a.
  • the helical compression spring 46 closes with the side surface of the pivot lever 45, the facing away from the movable contact piece 53, an obtuse angle; these Position, ie the closed position, thus forms a first stable position in which the Helical compression spring 46, the movable contact piece 53 via the pivot lever 45th against the fixed contact piece 52 and at the same time the pivot lever 45 in the Counter bearing 43 presses.
  • the coil spring 46 is with the end opposite to the coupling piece 55 is connected to a trained as a journal housing bearing 62 and is thus supported to generate the spring force on the housing. Also will be on this Housing bearing 62, the coupling piece 55 through a slit-shaped cutout 63 led.
  • the central axis of the helical compression spring 46 forms with the longitudinal axis of the pivot lever 45 in the off position an obtuse angle, the fixed contact piece 52 is open.
  • the arrangement of the bearing point 62 and the abutment 43 is selected so that the Dead center approximately forms an angle of 45 ° with the mounting plane, these Dead center approximately in the middle distance between the fixed contact piece and the stop 60 is located.
  • the geometrical relationships may be the case with other housing structures and other housing contours adapted to be different.
  • the coupling piece 55 is stamped as sheet metal part of sheet metal, wherein the side surface the sheet metal part parallel to the inner surface of the broad side wall of the housing base 11th extends.
