Definitions

  • the invention relates to a switching device, in particular an electrical control or regulating device, as is preferably used for the operation of electrical devices, such as heating devices.
  • Switching devices of this type have an electrical connection unit with at least one connection element, provided that the switching device is assigned to an electrical supply or discharge line.
  • the switching device itself can switch a power current, a signal current or the like on and off or toggle it, but at the same time it can also be suitable for controlling another medium.
  • the base body of a temperature controller forming a housing, has flat tabs on the back at different angular positions and distributed approximately over the entire back on.
  • a similar arrangement is also provided in the temperature controller according to US-PS 42 74 546 and DE-AS 23 28 887 or in the circuit breaker according to US-PS 26 47 962. It has been shown that such connection elements scale relatively easily during operation and can therefore rise sharply in terms of electrical resistance.
  • the invention has for its object to provide a switching device of the type mentioned, in which disadvantages of known solutions can be avoided in a simple manner.
  • a securely electrically conductive connection of the connecting member or members to the respective counter member should be ensured.
  • a separate holder or fuse is provided for the respective counter member, which can have one or more connections for connection to one or more connection members.
  • the counter member should not only be secured by the engagement in the connecting member, but also by a further, separate engagement in a further component that is fixed in position relative to the respective connecting member; this component can be fixed in position relative to the base body e.g. be arranged in such a way that it is at least partially arranged or held on an inherently stable electrical conductor part for the connecting element.
  • the respective conductor part itself is expediently rigid and possibly electrically insulated on the base body.
  • the additional bracket is at least partially secured in that it is attached via at least one plug connection. If this plug connection is made directly opposite at least two or three conductor parts or connecting members, this results in a very high mechanical strength.
  • the additional holder gives the respective counter member a play-free fit on the associated connecting member, which reduces the risk of oxidation.
  • the design according to the invention is also conceivable for screw connections, but is particularly advantageous for connection plug-in connections which can only be joined or released by an essentially linear plug-in movement. All the connection members assigned to the holder can be connected and disconnected simultaneously with the counter-members combined to form a common plug.
  • an electrical shield can be provided between the connection members and the switch, which shield is expediently formed by the holder. If the switchgear has a cover that can be removed from the base body, the shielding is maintained even when the cover is removed.
  • connection unit can, for example, have the connection elements countersunk and essentially shielded on all sides in an insulating housing which is accessible from the outside of the device housing, if the housing cover is attached.
  • This insulating housing can be a component separate from the cover or can be formed by a one-piece attachment of the housing cover. In any case, it expediently forms at least one plug socket which is open to the rear of the switching device and opposite the socket opening of which the counterpart can be supported directly or indirectly via the associated plug.
  • the connection unit can also be designed in the manner of a printed circuit board which is connected to the connection members on the side facing away from the counter.
  • the above-mentioned embodiments can also be provided in any combination in the same connection unit.
  • the connection unit according to the invention is very easily accessible with a space-saving design and high strength.
  • the conductor parts or the described components of the switching device can be designed in particular according to EP-A-89 123 597, to which reference is made for further details and effects.
  • the connection unit is in this case adjacent to a free end of a switching arm for the switch, the conductor parts directly connected to the switch or its contacts being approximately parallel to the area between their attachment to the base body and the transition into the connecting elements Longitudinal direction of the switching arm and approximately parallel to its arm plane and to the plate plane of the approximately plate-shaped base body are provided.
  • the conductor parts can be securely supported flatly on the base body, so that the additional holder has a very secure hold despite essentially exclusive attachment to at least two conductor parts, without a direct connection to the base body being necessary.
  • the holder can additionally be secured with respect to the base body in particular in the direction in which it is connected by a plug connection to the connecting members or conductor strips.
  • connection unit For a protected position of the connection unit, its additional holder expediently extends at most to the level of the rear of the housing or cover of the switching device, from which it can be slightly behind. Over the associated end or the corresponding edge of the base body However, the connection unit or holder can partially protrude or be completely offset to the outside relative to this end.
  • the switching device 1 has an approximately plate-shaped, essentially two-part base body 2 with a metal support body 3 and a plate-shaped, ceramic insulating body 4 rigidly attached to one end, which extends far in the longitudinal direction of the base body 2 over the support body 3 protrudes.

  • each conductor part forms, by means of a cutout on its end edge, two plug-in pins which are rectangular in cross section and adjoin its longitudinal edges .
  • the bracket 30 is formed essentially exclusively by an approximately flat wall plate 34, which does not protrude laterally and on the front over the insulating body 4 and on its side facing away from the base body 2 in the manner of a printed circuit with conductor tracks 35, 36, 37 for each connecting part is coated.
  • the narrow ends of the conductor tracks 35, 36, 37 lying parallel to one another and directed towards the rear of the switching device form the connecting members 6.
  • the conductor tracks 35, 36, 37 are each widened in the area of the associated plug-in openings 33 to form large-area soldering sections 38 which are insulated from one another and are penetrated by the plug-in openings 33 for the associated conductor part 24, 25, 26.

Adjacent housing pockets are separated from one another by partitions 44 which protrude from a top wall 45 of the extension 43. Furthermore, the pockets associated with the connecting members 6a are shielded from the snap switch 5a by transverse walls 46.

  • Securing members such as resilient latching hooks 39b, can protrude beyond the outside of the bottom wall 49, which overlap the end edge 31b and engage around the front of the insulating body 4b with hook attachments, so that the housing 43b is positively secured against removal from the conductor parts or connecting members 6b.
  • the latching hooks 39b can be non-contact with respect to the end edge 31b.
  • the housing 43b forms an additional shielding wall 34b, which lies immediately adjacent to the associated end wall of the housing cover.
