Definitions

  • the invention relates to an electromagnetic switching device with a coil and with a connecting terminal device for the electrically conductive connection of the winding end of the coil to the end of a power supply line, the connecting terminal device being a connecting piece to which the winding end of the coil is connected, and a screwable connector Has clamping screw for clamping the end of the power supply line.
  • connection terminal devices are often connected to the ends of the inductive coil immediately after completion, for example in a soldering process, but this entails the risk that the connection screws screwed into a connection angle become loose due to vibrations during a transport process in operation or on the shipping route and can even fall out if they are not so tightly screwed to the connection bracket that the screws cannot be removed automatically.
  • a tight screw connection is also undesirable, since in this case it is necessary to unscrew the connecting screw before connecting a connecting cable.
  • the object of the present invention is to eliminate the disadvantages described above or at least to reduce largely, and in particular to provide a terminal device for the described case of need, in which the connection screws can not be lost as long as a ichtung with a Harveyklemmenvor- 'provided inductive coil not with 1 em electromagnetic switching device is mounted, md in which also a subsequent automatic tightening the terminal screw as a result of transport J orter commonlyerept od. like.
  • the connecting piece is advantageously designed as a connecting bracket, one leg of which holds the clamping screw and the other side of which the contact lug and additionally a strain relief lug is formed.
  • the strain relief tab and the contact tab are attached in a U-shape to the connection bracket; the winding end is then inserted into the interior of the U and held therein by compressing the U-shaped strain relief tab and contact tab.
  • connection bracket for the contacting of winding ends of a coil and the connection screw that can be screwed into the thread with the pressure washer held captively on its head are combined with a separate cover molding, which is able to hold the connection bracket and the clamping screw equipped with a pressure washer captively.
  • a molded cover part provides increased protection against contact in the assembled position of the electromagnetic switching device.
  • assembly and connection of the winding end is considerably simplified.
  • connection bracket To hold the connection bracket in the interior of the cover molding, latching means are provided on both sides of the connection bracket, for example lugs which engage in grooves arranged in the cover molding or vice versa. Combinations of locking lugs and opposite grooves are also possible. This arrangement ensures that the connection bracket is held captively in the interior of the molded cover part.
  • the molded cover part is designed as an essentially rectangular cap, into which the connection angle and the clamping screw can be inserted from an open cap side and in which the clamping screw is held captively even in the position unscrewed from the connection angle.
  • the molded cover part can be outwardly directed, supporting and given if have locking parts that interact in the assembled position with corresponding formations on the housing.
  • a screw opening surrounded by a cylindrical elevation is advantageously provided on the cover molding on its upper wall adjacent to the open cap side, the center point of which coincides with the axis of the clamping screw after assembly of the connection angle and the clamping screw.
  • the wall facing the inside of the molded cover part has two inclined surfaces serving as a stop surface for a roof-shaped pressure plate held at the head of the clamping screw to be assigned in the area around the screw opening.
  • FIG. 1 is used again for further explanation.
  • To clamp the winding end 13 of the coil (not shown), it is fed to the tabs in such a way that the stripped end 19 of the winding end 13 leads into the bending area of the contact tab 12, the end of the insulated area the winding end 13, however, is inserted into the bending area of the strain relief tab 11.
  • both tabs are squeezed together, it may be expedient to expose the contact tab 12 to an increased pressure in order to achieve a particularly good and permanent contact connection between the stripped end 19 of the winding end 13 and the contact tab 12.
  • connection screw 20 with a roof-shaped pressure plate 22, which is held captively on its head 21, is now screwed into the threaded opening 14 fairly far or even up to the stop.
  • the molded cover part 24 is equipped with a screw opening 33 surrounded by a cylindrical elevation 32, the center of which coincides with the axis of the connecting screw 20 in the position mounted with the connecting bracket 10 and the closing screw 20.
  • a recess 34 which is located in a side wall of the molded cover part 24, has the mounted position of this molded cover part 24 in a switch housing in the direction of the housing exterior.
  • This recess 34 is used for the introduction of connection lines (not shown) for the inductive coil.
  • a flat surface 35 is provided on a lateral outer wall of the molded cover part 24, which is approximately adjacent to the recess 34 and serves to receive coil data and / or a clamping designation in the form of an imprint, an adhesive label, hot stamping or the like.
  • This area 35 is to be characterized as a designation area.
  • an upper housing part 42 can finally be placed on the lower housing part 38.
  • This upper housing part 42 is also only indicated. It can be seen from the illustration, however, that after the housing parts 38 and 42 have been assembled, the completely equipped molded cover part 24 is clamped between the corners of the housing parts mentioned and is held immovably here.
  • FIG. 3 A view of the assembly, as described, mounted and clamped between the housing parts 38 and 42 is illustrated by FIG. 3, which was already considered previously.
  • FIG. 4 shows an embodiment variant which grants a thrust washer particularly favorable support.
  • This illustration illustrates a vertical section through the upper region of a molded cover part 43, in which the wall pointing into the interior of this part in the region around a screw opening 44 has two stop surfaces for a roof-shaped thrust washer 46 held on the head of the associated connecting screw 45 has inclined surfaces 47 and 48.
  • Such a shaping of the inner wall of the molded cover part 43 in the area mentioned prevents an undesired inclination of the thrust washer 46, which means a further simplification and, above all, an additional guarantee for correct assembly.
