Definitions

  • the invention relates to a safety switch with a switch housing and one fixed to the end face in several predetermined angular positions Switch head.
  • the switch housing also includes the mechanical and electrical or electronic components installed.
  • a mechanical switching element mounted, which from one not to the safety switch belonging actuator is switched.
  • Such a mechanical The switching element is, for example, a ratchet wheel.
  • the invention has for its object a safety switch of the beginning type described in more simple manner so that the setting of the switch head on the switch housing in the various angular positions in is possible in the simplest way without using lost parts. About that in addition, the surface pressure emanating from the fastening screws is to be reduced will.
  • a rigid positioning element which is releasably attached to the switch housing and provided with a securing element, which in the position connected to the switch housing with the switch head is engaged and in the released position for rotating the Switch head can be brought out of engagement with this.
  • the positioning element is made of a rigid material, preferably steel manufactured and also designed so that the exerted by the mounting screws Surface pressure over the entire contact area between the switch housing and the positioning element is distributed.
  • the switch housing is a guide element for - with respect to the longitudinal axis of the switch housing - radial movability of the positioning element. Because the guide element is firmly attached to the switch housing is positioned or molded, the positioning element can only be moved radially so that the securing element out of engagement with the Switch head can be brought.
  • the guide element and the positioning element are designed so that a separation is not possible, so that the positioning element is captively arranged on the switch housing.
  • the safety switches are equipped with a locking pin that engages in the switch head provided, which engages in the ratchet, for example.
  • the central longitudinal axis of the The switch housing then coincides with the longitudinal axis of the locking bolt.
  • the positioning element has screw holes for fixing to the switch housing. This can by at least a screw screwed into the wall of the switch housing the positioning element be determined.
  • the guide element be designed as an angular web, which is attached to the switch housing or is integrally formed, wherein the positioning element has an opening into which a Legs of the angled web engages.
  • the angular web is expediently in one piece formed with the switch housing.
  • the free bar is perpendicular to Central longitudinal axis of the switch housing or to the locking pin. Because the positioning element has an opening, the radial displacement of the Positioning element specified. Due to the appropriate design, it is captive coupled to the switch housing.
  • the securing element is a web, which is designed in the manner of a feather key and that the switch head has a sleeve, which is provided on the outside with several locking grooves, in which the optional Engages web.
  • the switch head or sleeve is four in Grooves running in the direction of the central longitudinal axis of the switch housing.
  • the positioning element is expediently determined by two Screws so that the positioning element also has two screw holes.
  • the safety switch shown in FIGS. 1 to 3 has a switch housing 10 and a switch head 11.
  • Components mounted in the switch housing 10 and in the switch head 11 are not shown.
  • the wall of the switch housing 10 facing the switch head 11 is included provided a bore 12, the central longitudinal axis of the central longitudinal axis of the switch housing 10 defined.
  • the switch housing 10 is also stepped on this side discontinued.
  • the wall of the switch housing adjacent to the bore 12 10 carries a positioning element 13.
  • the positioning element 13 is a flat, rigid component, which is preferably made of steel. It is with provided two spaced screw holes 14, 15 to it to be screwed to the switch housing 10 by screws, not shown.
  • a guide element in the form of an angular web is attached in the middle.
  • the free, vertical tavern standing to the central longitudinal axis of bore 12! reaches into an opening of the positioning element 13 including.
  • the free area extends into the bore 12.
  • the switch head 11 is on the switch housing 10 facing side equipped with a sleeve 18 which is fixed to the Switch head 11 is connected or is integrally formed. On the outside The circumferential surface is this sleeve 18 with four to each other at an angle of 90 ° offset grooves 19 equipped.
  • These grooves 19 run in the direction of the central longitudinal axis the sleeve 18 or the bore 12.
  • the sleeve 18 is also with a provided central bore 20.
  • the securing element 17 and the grooves 19 are matched to each other so that the securing element in the assembled position 3 engages finally in one of the grooves 19 as shown in FIG. This creates a positive connection between the switch housing 10 and the switch head 11 reached. It follows from the figures that the switch head 11 in the illustrated Embodiment in four different positions with the switch housing 10 is to be connected. Depending on the installation position of the fuse switch, this can Position can be changed. First, the two are not shown, the Loosen positioning element 13 fixing screws. The positioning element 13 can then be moved as far as shown in FIG.
  • the switch head 11 can then be turned freely in both directions. It is by the Angle bar 16 prevents separation of the positioning element 13 from Switch housing 10 is possible.
  • the switch head 11 is also transverse to Longitudinal axis of the sleeve 19 standing, rectangular in cross-section opening provided, in which an actuator, not shown, when using the switch intervenes.
