Definitions

  • the present invention relates to an electromagnetic switching device, in particular a contactor with an electromagnet fastened in a housing and with at least one magnetic coil and its coil former, which bears only in one direction and which projects in the housing and which fastens in the housing.
  • an electromagnetic switching device in which a coil body carrying a magnetic coil is provided either with two coil terminals projecting in only one direction, or with three coil terminals, with three coil terminals two in one direction and one in the opposite direction Direction aligned, but is electrically connected to one of the other two.
  • the magnetic coil can either be connected from one side only or with one connection from both sides.
  • the coil body carrying the magnetic coil can only be installed in the housing in a certain position.
  • the contactor when the contactor is assembled with another device, in particular with a circuit breaker, as is known, for example, from FR-A1-2695754, the coil terminals are in an inaccessible position on the side of the contactor facing the circuit breaker if the contactor was intended for assembly with an overcurrent relay and / or a fuse as short-circuit protection.
  • the contactor can be optionally assembled with a device to be connected to one of the two sides of the contactor, such as a fuse or a circuit breaker, with the label either being turned upside down in one of the two cases, or offset by 180 ° must become.
  • the object of the present invention is to develop an electromagnetic switching device of the type mentioned in the introduction, in which the coil connections of the electromagnetic switching device can be adapted to the mounting arrangement of the switching device in a simple and economically advantageous manner, without having to accept an upside-down lettering have to.
  • the object is achieved in that the coil body can be inserted into the housing in two positions offset by 180 ° about the winding axis of the magnet coil.
  • This simple and economically advantageous measure allows the coil connections to be arranged on the easily accessible side of the electromagnetic switching device, the labeling of the switching device itself remaining unchanged.
  • both the housing and the coil body are provided at the abutting positions with effective, interlocking positioning parts in both 180 ° positions of the coil body.
  • the positioning parts secure the position of the coil body in the housing in the two positions of the coil body offset by 180 °.
  • FIG. 1 shows the escape pattern of the most essential parts of an electromagnetic switching device housed in the lower part 1 of the housing.
  • the core 2 of the electromagnet can be fastened by a metal strip 4 in the lower part 1 after mounting two resilient damping rods 3.
  • Short-circuit rings 5 with elastic damping rods 6 are snapped onto the two legs of the core 2.
  • a bobbin 7 is shown in Fig.1 without winding.
  • two coil connecting pieces 8 projecting only in one direction are provided on the coil former 7.
  • the connecting wires, not shown, can be connected to the coil connecting pieces 8 with clamping screws 9 and clamping claws 10.
  • a cover 11 is used to cover the live parts.
  • the coil body 7 can be pushed into the middle leg of the core 2 in two positions offset by 180 ° about the winding axis of the magnet coil and can thus be accommodated in the housing. Both the lower part 1 of the housing and the coil body 7 are on Provide the abutting points with effective, interlocking positioning parts 12 in both 180 ° offset positions of the bobbin 7.
  • FIG. 2 shows the cross section of a complete electromagnetic switching device with coil connecting pieces 8 on the left in the drawing.
  • the coil former 7 is clamped and held in the housing by the upper part 13 of the housing.
  • the armature 14 with the movable contact pieces 15 and the fixed contact pieces 16 are accommodated in the upper part 13 of the housing, to name only the most essential parts.
  • the upper part 13 is fastened to the lower part 1 of the housing by means not shown.
  • FIG. 3 the electromagnetic switching device shown in cross section in FIG. 2 is visible in a top view with the upper part 13 removed. In this position, the bobbin 7 can be pulled out of the lower part 1 of the housing. In Figure 3 it can be clearly seen that the coil connection pieces 8 are on the left side of the housing.
  • FIG. 4 shows the same electromagnetic switching device in cross section as in FIG. 2.
  • the coil connection pieces 8 are on the right and not on the left side of the switching device and that the entire coil body 7 is compared with that in FIG shown bobbin 7 is offset or rotated by 180 ° about the winding axis of the solenoid 17.
  • FIG. 5 shows the electromagnetic switching device shown in cross section in FIG. 4 without an upper part 13. It can be clearly seen from the comparison of FIGS. 3 and 5 that the bobbin 7 has been moved from the position shown in FIG. 3 by shifting around the winding axis of the magnetic coil 17 by 180 ° into the position visible in FIG. When the bobbin 7 is displaced by 180 ° about the winding axis of the magnetic coil 17, the position of the lower part 1 and the upper part 13 of the housing remains unchanged. The inscriptions on the surface 18 of the housing remain unchanged despite the position of the coil connecting pieces 8 changed by 180 °.
  • the electromagnetic switching device described is suitable for assembly, for example with a fuse on one side of the switching device or alternatively with a circuit breaker on the other side of the switching device with the same labeling of the switching device and with easily accessible coil connecting pieces 8 on the free side of the switching device.
