Definitions

  • the invention relates to a protective conductor terminal, in particular in a terminal block housing, the foot of which serves as a tension bracket and has supports in a deep and in a shallow recess for support on hat-shaped support rails in cross section and holds a compression spring which springs with sliding zones against the recesses and when Put on a mounting rail to make contact.
  • An electrical terminal block is known, which is designed as a protective conductor terminal (DE-PS 31 26 535), in which a pressure bracket, under the force of the clamping screw of an electrical connecting terminal, presses against a rail edge of a mounting rail inserted into the recesses of the tension bracket.
  • the electrical contact should be achieved by teeth in the support of the associated recess for the rail edge in the drawbar.
  • the protective conductor connecting terminal does not initially find a secure hold when it is placed on the mounting rail, which disturbs during assembly.
  • a secure hold on the mounting rail is achieved regardless of the clamping screw, but an additional spring is used for this.
  • the invention has for its object to develop a protective conductor terminal that finds a secure hold already when it is placed on the mounting rail, but does with a single compression spring.
  • the solution of the described task is according to the invention that the compression spring due to its shape with respect to the recesses in the foot and with respect to abutments on the foot when placing the foot with the deep recess on a mounting rail and tensioning and moving the foot to grip around the rail edge caused by the flat recess by a force component parallel to the rail plane.
  • the slide-on zones are aligned here so that the compressive force of the tensioned compression spring has a component which is directed parallel to the rail plane to the flat recess and, in counteraction with the rail, pulls the foot with the flat recess onto the rail edge.
  • the sliding movement on the sliding zone also allows dirt or oxide layers to be rubbed off, so that electrical contact is ensured.
  • the protective conductor terminal can generate the forces for transferring your foot into a secure hold on the mounting rail according to claim 2 only at the deep recess, according to claim 3 solely by the sliding zone on the flat recess or according to claim 4 by mutual support.
  • the deep recess in the foot of the protective conductor connection terminal enables an oblique placement on a mounting rail according to the shape and inclination of the support for the rail edge, the placement and removal is facilitated. On the other hand, this also gives a visual indication of which terminal is attached and which terminal is only loosely attached.
  • a protective conductor terminal is shown with the housing cut open.
  • a foot of an embodiment is shown in side view, which can be part of a protective conductor terminal according to Fig. 1 or another terminal.
  • Fig. 3 the foot of Fig. 2 is shown in bottom view.
  • FIG. 4 illustrates how the foot according to FIG. 2 is placed under tensioning the compression spring.
  • Fig. 5 the foot is shown snapped onto a mounting rail.
  • Fig. 6 an inclined foot is shown. The foot is in this position when loosening; it can also be brought into this position when it is put on.
  • a protective conductor terminal is illustrated, the foot of which is designed according to the invention.
  • the protective conductor connection terminal 1 has a foot 2, which forms a pull bracket for attachment to a mounting rail.
  • he has in a deep recess 3 and in a flat recess 4 supports for support on hat-shaped support rails 5 - according to FIG. If you put the protective conductor terminal 1 on a mounting rail, it is tensioned, which also ensures electrical contact.
  • 1 is in the exemplary embodiment part of a terminal block with further connection levels 9 and 10.
  • the compression spring 6 is tensioned by its shape with respect to the recesses 3, 4 in the foot 2 and with respect to abutments 11, 12 on the foot 2 when the foot with the deep recess 3 is placed on a mounting rail. Under the force of the tensioned compression spring, the foot 2 is then shifted until the flat recess 4 is gripped around the rail edge. This causes a force component of the spring in each case parallel to the rail plane in counteraction with the rail.
  • the compression spring 6 As a holder for the compression spring 6 13 in a flank U-shaped bent foot 2 according to FIGS. 2 and 3 in its flanks 13 14 excluded. Lugs 15 of the compression spring 6 engage in this, with play being left so that the compression spring 6 remains somewhat displaceable in the longitudinal direction in the foot 2.
  • the compression spring 6 is formed from round wire, which is bent at one end and returned over the entire length of the spring, as can be seen from FIG. 3.
  • the spring jet not only has the advantage of strong compressive forces, but also low friction and good contact, since the compression spring rubs dirt and oxide layers in a narrow channel when it slides on a mounting rail.
  • Fig. 4 it is illustrated how a protective conductor terminal with two sliding zones 7 and 8, with its foot 2 is placed on a mounting rail 5.
  • a mounting rail edge is inserted into the deep recess 3.
  • the compression spring 6 is supported between its holder, window 14, in the foot and the deep recess 3 against an abutment 11 on the foot. With its rounded end, it engages in the deep recess 3, the apex 16 still lying outside the rail edge when the position is raised by the rail thickness.
  • the compression spring 6 is at the rail edge in an imaginary sliding plane 17.
  • a horizontal component of the spring force oriented with reference to the drawing acts, which pushes the foot 2 against the rail edge and thereby pulls the flat recess 4 onto the other rail edge.
  • the compression spring 6 When the compression spring 6 is tensioned, it changes from a position according to FIG. 2 into a position according to FIG. 4.
  • the other rail edge slides along the slope 18 of the foot in the flat recess. 5 is snapped onto the mounting rail, the end of the compression spring 6 is supported against an abutment 12 on the foot.
  • This abutment is seen in the longitudinal direction of the foot near the support 19 of the compression spring 6 on the rail edge in order to form a hard spring for the terminal seat and for making contact.
  • the compression spring is then raised by the rail thickness.
  • the compression spring 6 can be supported at least shortly before against the abutment 12 in order to increase the spring force.
  • the compression spring 6 between the flat recess 4 and the position of the adjacent inner rail edge 20 of an inserted mounting rail has a sliding zone 8 according to the exemplary embodiment in a sliding plane 21 which runs obliquely to the rail edge, as shown in FIG Carrier rail can be snapped on.
  • This slide zone on the flat recess supports the effect of the slide zone on the deep recess.
  • the end of the compression spring 6 between the support 19 according to FIG. 5 at the rail edge and the abutment 12 at the foot 2 provides essential holding forces for the protective conductor terminal, when it is snapped onto a mounting rail.
  • the compression spring 6 conveys further holding forces with its other end depending on the length between the abutment 11 at the base 2 and the support in the sliding plane 17 at the rail edge, in connection with the clamping point in the window 14.
  • the forces which ensure that the Feet with its shallow recess 4 on the rail edge is provided by the sliding planes 17 and 21. It is sufficient if one of the sliding planes 17 and 21 can take effect. These can support each other with two levels of glide.
  • the deep recess 3 in the foot 2 enables an oblique placement on the mounting rail by the shape and / or inclination of the support 22 for the rail edge. This position can be achieved in particular if the foot 2 is released from the mounting rail 5 by lateral pressure on the rail edge at the deep recess 3. If a slide zone 8 is formed on the compression spring 6 in front of its opposite end, the inclined position of the foot according to FIG. 6 can also be allowed for assembly, since the slide zone 8 then ensures that the foot 2 is securely pulled up and held during assembly.
