Definitions

  • the invention relates to an electrical circuit breaker according to the first part of claim 1.
  • a switch lock has become known, in which a cam is formed on the test button of a residual current circuit breaker, which engages in the switching mechanism after the test button has been pressed in and rotated, thereby preventing the switching mechanism from latching, the test button being lockable in this position is.
  • a switch position indicator is not created with this arrangement. Rather, the lock is only provided in connection with a test button on a residual current circuit breaker.
  • the object of the invention is to provide a circuit breaker of the type mentioned, in which the switch position indicator is combined with the switch-on lock.
  • both a switch-on lock which can be actuated manually from the outside and a switch position indicator are achieved by means of a component which forms a unit.
  • the first slide which acts together with the release lever and on which the rotating part acts, serves as a release lock.
  • the second slide which cooperates with the contact lever, is moved by the latter from a first position, in which it is not, to a second position, in which it is very clearly visible; in this position he sits below a window opening or, according to the invention, below the rotating part, which according to claim 12 is clearly transparent. In this visible position, the second slide indicates that the switching device is switched off, the contact pieces are separated, so that work can be carried out in the network behind the switch. If the isolating distance then complies with the regulations, that is to say is large enough, then the switching device designed according to the invention can be regarded as an isolating switch, that is to say as a switching device with isolating function.
  • the rotating part together with the first slide serves as a switch-on lock.
  • the switch-on lock can be actuated from the outside, in such a way that in a first position of the rotary part the switch-on lock is ineffective and in a second position, because then the cam engages in the path of the first slide, causing the first slide to move and thus a release movement of the release lever is hindered.
  • the mounting of the rotating part can be seen from the dependent claims 9 and 10, respectively. So that unauthorized persons cannot remove the switch-on lock, a profile is formed on the rotating part according to the characterizing feature of claim 11, which profile can only be adjusted by means of a tool that can be applied from the outside.
  • the profile is preferably a slot into which a screwdriver can be inserted.
  • the switch position indicator is no longer designed to be rotatable about an axis, but can be displaced in the guide part in accordance with the characterizing feature of claim 1.
  • the arrangement according to the invention is accommodated in a housing 10 of a circuit breaker, of which only individual parts forming or tangent to the invention are shown. Otherwise, the circuit breaker according to FIG. 1 is supplemented in the usual way by a thermal release, by further parts of the switch lock and a magnetic release in addition to an arc-quenching plate package.
  • a movable contact lever 11 is rotatably supported by means of an axis 12, at one end of which the movable contact piece 13 is attached, which interacts with a fixed contact piece 14.
  • the contact lever 11 has an extension 15 with which it is rotatably coupled to a connecting bracket 16 which is articulated at its other end via a wire bracket 17 with a switch toggle 19 pivotally mounted about a fixed axis 18.
  • the switching lock described above which includes the contact lever 11, the connecting strap 16, the wire bracket 17, the switching knob 19, a ratchet lever 40 and a release lever 27 is mounted between two boards 41 and 42.
  • the housing 10 of the circuit breaker consists of two housing shells 22 and 23, between which a guide part 20 is received and mounted in a stationary manner. How the guide part 20 is mounted. is of little importance for the invention; Appropriately, grooves or recesses are provided on the housing shells 22 and 23, into which the formations 20a and 20b, 20c and 20d engage.
  • a first slide 26 is guided in a groove (without reference numerals) in the direction of the pivoting movement of the switching knob 19, which projects beyond the guide part 20 to the right and interacts with the release lever 27, which is also mounted on the axis 18 .
  • An upwardly projecting nose 25 is formed on the first slide 26 and is concealed in FIG. 1.
  • a rotating part 21 which has an eccentrically formed cam 24 which, as can be seen in FIG. 1, engages in the range of motion of the nose 25 on the slide 26.
  • the rotating part 21 has two flange-like collars 28 and 29 which are arranged at a distance from one another and between which an annular projection 30 engages, which is formed on the two housing shells 22 and 23 on two recesses (22a, 23a) pointing radially inwards; the two housing shells 22 and 23 thus delimit a circular receiving space 31 for guiding the rotating part 21.
  • the rotating part 21 has a slot 32 so that the rotating part 21 can be rotated in the direction of arrow P.
  • the rotating part 21 is made of a clear material.
  • a second slide 33 is slidably guided on the guide part 20 in a groove, also not shown, which has a plate-shaped upper part 34 and a pin 35 attached or molded vertically thereon.
  • the pin 35 is simultaneously guided in a slot 36 in the guide part 20.
  • Fig. 3 shows the switching device in its off position.
  • the movable contact lever 11 has been pivoted clockwise about the axis 12;
  • the pin 35, and with it the upper part 34, has been displaced to the right under the clearly transparent rotating part 21 via an angular extension 37.
  • the second slide 33 has thus become visible. This suggests. that the switch is in the off position.
  • To switch on the switching knob 19 is rotated in the direction of arrow F, whereby the contact lever 11 moves counterclockwise in the switch-on position and the pin 35 and thus the slide 33 is moved into the position in which it is no longer visible and which indicates the switch-on position.
  • Fig. 1 it can be seen that the protrusions 20c and 20d (only the protrusion 20d is visible) protrude approximately into the area upwards in front of the guide part 20, which lies between the two flange-like collars 28 and 29.
  • the bulge-like region shown in FIG. 1 is the lateral shape 20d, which engages in a housing groove (not shown) on the housing shells 22 and 23. Their width coincidentally corresponds to the diameter of the recess 31.
  • the formations 20a and 20b lie in a different plane than the two formations 20c and 20d; The formations 20a and 20b lie approximately in the area in which the upper part 34 is located.
  • the guide part here has the reference number 50, but essentially corresponds in its function to the guide part 20.
  • the guide part 50 While the guide part 20 is guided in the housing, the guide part 50 (see FIGS. 5 and ff.) Is held on the circuit boards 41 of the key switch.
  • the guide part 50 has a plate-shaped basic structure 51, at one end of which fork-like fastening hooks 52 and 53 are attached.
  • These fastening hooks are arranged at a distance from one another and, as can be seen from FIG. 10, comprise two L-shaped hooks 54 and 55 shown in FIG. 11, which are integrally formed on the boards 41 and 42 and with their free leg ends 56 and 57 assign to each other. So that the fastening hooks do not slip off the leg ends 56 and 57, they have barb-like projections 60 and 61 at the ends of the fork tines 58 and 59.
  • a first extension 65 and two further extensions 66 and 67 are located on the opposite edge of the basic structure 51, the first extension 65 clearly projecting beyond the two further extensions. Between the individual extensions 65 to 67 slots 68 and 69 are provided, the function of which is explained below.
  • a display slide 70 is guided, which has an elongated, rectangular contour and in its rear region has a C-shaped profile 71 which, as can be seen from FIG. 7, completely surrounds the extension 65 .
  • an extension 71a is provided on one side of the indicator slide, on the free end of which a pin 72 is formed, the extension 71a together with the pin 72 corresponding to the pin 35 in the embodiment according to FIG. 1.
  • the extension 71a together with the pin or projection 72 engages in the path of movement of the movable contact lever 11 (see FIG.
