Definitions

  • the invention relates to a toggle connection for a single-pole switching devices Composite multi-pole switching device according to the preamble of Claim 1 (DE-A-2 540 745)
  • the control gags are an elastically deformable expansion part formed by a slot open at both ends in the lever handle continuously between two spacable, flexible legs is arranged. As a connecting part of those located side by side in the axial direction The control knob is a metal pin that spans the switchgear is pressed between the legs of all expansion parts.
  • the invention has for its object a gag connection of the type mentioned To improve inexpensively so that the individual control knob despite one slim outlet cross-section from the single-pole switch housings afterwards twist-proof thanks to a torsion-resistant, manually manageable handle can be coupled, the handle bar in the axial direction by post-shrinkage caused longitudinal compensation between the side-by-side, preferably permanently ensure switch housings made of thermosetting plastic should.
  • the invention has the advantage that after stringing together the single-pole Switches, for example to a two-, three- or four-pole switching device, subsequently a correspondingly long handle bar with a simple plug in the gag fragments protruding from the switch housings can be snapped into place on the front. All control knobs are then coupled to each other so that they cannot rotate entire control knob appears like a solid common component, though due to climatic fluctuations and post-contraction of the switch housing caused dimensional changes between the laterally adjacent Single poles can be bridged with sufficient longitudinal play. At the same time it is Handle bar ergonomically easy to handle and easily according to customer requirements to be variable in terms of both color and shape. The construction of the Forming tools for producing the toggle parts are also not special Claims made, as compared to the previous practice, there is even a total Tool simplification results.
  • the toggle connection preferably made of a thermoplastic for a Multi-pole switching device has a shortened control knob 1 for each single pole which is predominantly within a range which is only indicated schematically in FIG. 4
  • Switch housing 2 arranged and there with its hole 1.1 on a Axis 2.1 of the housing is pivotally mounted.
  • Each control knob 1 protrudes with a short, relatively slim and low volume gag fragment 1.2 from one housing opening 2.2 adapted to its on and off switch position and is with one overlapping the single-pole switchgear on their operating front Handle 3 can be connected later.
  • the handle bar 3 is according to the Number of individual poles and in the specified pitch, usually 18 mm wide provided with approaches 3.1, the rectified on their wedge-like, rounded Lower edge 3 'of the approximately heart-shaped profile cross section are arranged above.
  • the approaches 3.1 in turn have an elongated profile with a semi-cylindrical End contours 3.11, 3.12 and a slightly narrower one in between Web 3.13, which is provided on both sides with sawtooth-like projections 3.2 (Fig. 1, Fig. 3).
  • the projections 3.2 are on the web 3.13 in the direction of the handle bar trained increasing.
  • there is a coding level on one end contour 3.12 3.3 set off with a coding level to be described in the Gag fragment 1.2 interacts and a correct connection between the Handle bar 3 and the control knobs 1 guaranteed.
  • each gag fragment is 1.2 from its upper narrow side a slot-like recess 1.3 is formed, 1.4 on both end faces is at least partially closed.
  • the gag fragment 1.2 thus forms around the Recess 1.3 a stable frame, but in the upper area on a Front is interrupted (as can be seen particularly well in Fig. 1), so that in Axis direction of the control knob two slightly deformable, narrow strips 1.5 with a total of gutter-like, adapted to the bottom profile of the handle bar 3 Surface are formed.
  • undercuts 1.6 are formed in the axis direction, as is particularly shown in FIG. 3 shows. These undercuts 1.6 can be shaped technically in the working direction of the Manufacture tools easily from the front of the control knob, such as it indicate end openings 1.7 without the stability of the recess 1.3 is adversely affected.
  • a coding level 1.8 can be made within the recess 1.3 form (Fig. 5), the dimensions of coding level 3.3 on the handle bar 3 is coordinated and specifies the correct insertion. If the Handle bar rotated 180 ° in the longitudinal direction puts the longer end contour 3.11 on the Coding level 1.8 and noticeably prevents the complete immersion of the Approaches 3.1 in the recesses 1.3.
  • a toggle connection is shown for a single-pole Switchgear composite multipole switching device, the single-pole switching devices arranged side by side around a common one Swiveling axis, made of a thermoplastic
  • control knobs by means of the individual control knobs overlapping rigid grip bar coupled are, with the control knob (1) on their up pointing narrow side with one in the axial direction running, closed on both faces (1.4) slot-like recess (1.3) are provided, which in turn to both sides in a plane perpendicular to the Axis direction (2.1 ') undercuts (1.6), and the handle (3) also made of thermoplastic with the pitch of the single-pole switchgear as well according to their number of cones protruding (3.1), which in the recesses (1.3) with sawtooth adapted to the undercuts (1.6) Projections (3.2) subsequently elastic and captive and can be locked against rotation, while in the longitudinal direction Handle bar (3) between the lugs (3.2) and the recesses (1.3) sufficient play to compensate for tolerances and Material shrinkage is
