Definitions

  • connection terminal for electrically operated devices, in particular household appliances with a replaceable device connection, with a lower part through a device wall recess and attachable to the device wall by means of latching terminal housing with a lid, which, in addition to a power cable connection with strain relief, is detachable within the device wall in the lower part Has plug connection for the device connection lines.
  • Such terminals - compare, for example, German Patent 35 40 135 C1 - serve on the one hand to carry out the assembly of the device connections as quickly and easily as possible. On the other hand, they are intended to provide the possibility of replacing the power cable without exposing the actual device connection lines. Finally, in the case of such connection terminals, the aim is also to be able to connect the device connection lines to the connection terminals as simply as possible, preferably in the form of plug connections.
  • the invention has for its object to design a terminal of the type mentioned so that it is tamperproof with a simple structure and at the same time also offers the possibility of integrating radio interference suppression.
  • the factory-made automatic assembly of the connection terminal in the rear wall of the device e.g. by a robot.
  • the contact parts of the plug connection are inextricably connected to the lines of the power cable, in particular crimped, soldered or welded, and that the cover is combined with the terminal housing to form a non-releasable unit.
  • connection terminal can be manufactured in a considerably more compact and thus more stable and also significantly less expensive manner. This fact facilitates the automatic assembly of the clamp at the factory, e.g. through automatic assembly machines or robots, which are sometimes already practiced industrially, but are increasingly being demanded by industrial users.
  • the intention of the invention is, however, that the replacement of a defective cable by the lay user of the household appliance is made impossible with the risk of incorrect reconnection of the mains cable. Rather, it is provided that in the event of a necessary repair, only the service man of the device manufacturer releasably unlocks the connection terminal with tools from the device wall and throws away the defective cable together with the terminal and replaces it with a new cable combination.
  • the loss of the connection terminal is more than compensated for by the cheaper construction of the connection terminal and the more rational assembly both in the factory initial equipment and in the repair.
  • the connecting terminal shown in Figures 1 to 4 comprises a terminal housing 1 with a cover 2.
  • electrical connector parts 4 are arranged which, on the one hand, are permanently connected to the lines 5 of the connecting cable by crimping, welding or soldering are and on the other side emerge as tabs 6 on the underside of the terminal housing to form a detachable plug connection for the device connection lines inside a device wall 11.
  • the training is such that after the assembly of the components and the non-detachable connection of the lines 5 of the connecting cable, the closed cover is inseparably connected to the terminal housing 1, so that there is no longer any access to the inside of the terminal and therefore also none at all Manipulations can be made.
  • This enables in particular the installation of a radio interference suppression that cannot be changed by the user and can be restricted in its function in the terminal housing, in order to avoid the transmission of interference from the interior of the device to the network.
  • a radio interference suppression device is not shown in the drawings for reasons of clarity.
  • the cover is welded to the terminal housing at three points 7, 8 and 9, the bolts 8 and 9 (see in particular FIG. 4) protruding through recesses 10 in the housing cover and then into these Recesses are welded.
  • Rigid hooks 12 are provided for the locking of the connection terminal in the rear wall of the device, which can only be released from the outside by means of a tool, which engage behind the rear wall after insertion of the connection terminal into a longitudinally enlarged cutout in the rear wall of the device and after displacement of the terminal in the direction of the cable entry.
  • An elastic latching hook 13 on the lower edge of the clamp engages in a recess provided in the rear wall of the device after the connecting clamp has been moved, thus preventing the clamp from being pushed back and unlatched.
  • the locking hook 13 can only be unlocked from the outside with a tool.
  • Figures 5 and 6 show a modified embodiment of a terminal according to the invention, wherein there is no cover for the terminal housing at all, but instead the terminal housing with the built-in electrical components has been cast or injection-molded around.
