Definitions

  • the invention relates to a residual current circuit breaker according to the preamble of the claim 1.
  • Residual current circuit breakers have one in addition to a number of other components Switching shaft with which the movable contact pieces of the residual current circuit breaker be operated.
  • Auxiliary switches are mounted on the side of such residual current circuit breakers, who have a contact point, the movable contact piece also with a switching shaft (auxiliary switch switching shaft) is operated; when an auxiliary switch to one Residual current circuit breaker is installed, then the switching shaft of the residual current circuit breaker be coupled with the auxiliary switch selector shaft.
  • the switching shaft has a coupling the residual current circuit breaker has a profiled recess on its end face, whose profile is adapted to the profile of the pin and into which the pin is pressed becomes.
  • the residual current circuit breaker is usually checked with the auxiliary switch attached and as Unity expelled; there is also a desire to retrofit the auxiliary switch to the Install a residual current circuit breaker.
  • the housing of the residual current circuit breaker an opening or opening in the area of the selector shaft have through which the pin can be inserted; so none Contaminants can get inside the residual current circuit breaker, this breakthrough is closed, for example, by means of an adhesive film.
  • there is no recess on the switching shaft of the residual current circuit breaker but a pin is provided that protrudes from the housing and into the Auxiliary switch is inserted when it is subsequently connected to the residual current circuit breaker to be grown.
  • the object of the invention is to provide a residual current circuit breaker of the type mentioned Type to create, on the one hand, a sufficient closure of the breakthrough and on the other hand, easy accessibility can be achieved
  • the housing wall adjacent to the end face of the selector shaft has a breakthrough made by one in the area of the breakthrough Recess in the outer wall of the slide valve opened or closed can be.
  • the slider which is made of plastic, is a rectangular flat component that has a tab in the central area, which is pressed out resiliently from a side surface and which is in the assembled state against a wall area of the housing outer wall supports or resiliently.
  • a step is provided on the outer wall of the housing, behind which the rebounding tab edge engages so that the slide is held immovably in this position.
  • An inclined surface adjoins the step in the direction of closing movement, which, starting from the step, encloses an acute angle with the outer wall of the housing and which corresponds approximately to the tabs in the relaxed state, so that if the slide is closed, the tab essentially against the entire surface Relaxed inclined surface so that the slide is also held in this position is.
  • FIG. 2 Reference is first made to FIG. 2.
  • the residual current circuit breaker shown schematically in FIG. 2 has a lower housing part 10, in which a number of components, not shown, such as. B. Total current transformer, switching contacts and the like. Housed and the by means of a Cover 11, which is only shown in dashed lines, is closed. On the lower housing part 10 is in the area of the separating surface between the lower housing part 10 and the cover, also called upper housing part 11, a strip-like projection 12 is provided, in which there is an opening 13, which is shown in dashed lines in the region of the end face 14 Switch shaft 15 is.
  • Fig. 2 it is shown that the opening 13 is open, whereas in the illustration 1, the opening 13 is closed by a slide 16 described below is.
  • Rectangular recessed recess 21 leading to the parting plane between the lower housing part 10 and upper housing part 11 has a wall 22 on which there is an inclined surface 23 connects that with the housing outer surface 20 to the parting line or parting plane between the lower housing part 10 and upper housing part 11 open acute angle includes.
  • This inclined surface is located in a slot 24 in the wall 22 and in the parting plane between the lower housing part 10 and the upper part 11 flows into.
  • the slider 25 is a rectangular flat component, one in one half the plane of the component 25 has the tab 26 pushed out, which is approximately in the one, shown in FIGS. 5 and 6, is located, whereas the upper half Half 25a serves to close the opening 13.
  • the bend axis 27 is located itself near the bottom edge (see Figs. 5 and 6), and between the bend axis 27 and the adjacent narrow side edge 28 is a rectangular Recess 29 in which a tool can engage.
  • L-shaped recesses 32 and 33 provided by the in the longitudinal edge 30 and 31 located arms 34 and 35 are formed in the direction of the upper half 25a and an outwardly facing nose 36 and 37 exhibit.
  • These lugs 36 and 37 protrude beyond the longitudinal edges 30 and 31 and serve thus the additional mounting of the slide 25 in the state shown in FIG. 1, in which the slider 25 with its narrow side edge 28 ahead of the parting plane is inserted into the slot 24, in which position the resilient tab relaxes, what is due to the inclined surface 23, and in which the opening 13 is closed is.
  • the lugs 36 and 37 keep the slide 25 in the closed Position. The residual current circuit breaker is delivered in this position.
