Abstract

Programmer for domestic dishwasher, the set of multicontacts of which is collected together in a panel for the connection of separate group plugs, characterised in that the outer housing of the programmer is furnished with fixing plates (9, 10), in the projecting exterior edges of which are cut sprocket holes (15) and coding slots (16).

Description

A- The invention relates to a programmer for machines

  domestic dishwashers, including the multicon-

  tacts is assembled in a panel for the connection of

  separate group files It concerns especially the rac-

  electrical cord of the multi-contact set of said programmer. In the case of programmers, also called

  control devices, minute switch contacts

  operated by control discs or cylinders

  cams are connected to flat plugs These electrical elements

  ques of connection are gathered in complete units of sets of contacts or in panels and are arranged on the casing, in an insulating way The other connection is carried out using a device with contact plugs, namely at the using an indivisible, common adapter, which is connected, via harness, cables or ribbon ducts, with the components of the dishwasher to be controlled, such as the circulation pump, the pump drain, heating, metering device and wetting agents or the like The plug-in adapter is finally screwed to the programmer housing (according to the technical sheet "control devices

  programs 2 HK 4 ", manufacturer Siemens).

  A dishwashing machine therefore requires a programmer comprising up to twenty four or more contact units The insertion force (respectively disengagement in the case of after-sales service) for a block

  indivisible to twenty four records is extremely high.

  For this reason, indivisible complete sheets of this type are used less and less for the manufacture of expensive household appliances and are replaced by

single group files.

  To do this, "a program control device

  for domestic machines "is known from DE 33 40 742 C 2.

  According to the state of the art, the programmer connection bars are arranged on the underside of the housing, and are connected to a separate distribution device, fixedly pluggable Inside said distribution device, the connections for separate group cards are deinterleaved, that is to say, are classified by group of elements and the associated contacts are gathered in a guide grid by another part The guide grid has coded bars and prevents incorrect insertion of the cards The complete distribution device is covered with a protective cover

box-shaped.

  This type of group plug connection device is relatively expensive and requires a large number

  separate intermediate pieces.

  The invention aims to create a simple and inexpensive connection possibility for a large number of

group files.

  This objective according to the invention is obtained by the fact that the external casing of the programmer is provided with fixing plates, in the projecting external edges of which are provided snap-in notches and

coding slots.

  The advantages obtained by the invention are of the following nature: For the connection of group cards, no

  intermediate or similar part is not necessary The har-

  necessary cables can be produced automatically

  Connection errors are reduced The type of connection allows the use of group plugs with one

  row can be fully automated

  tick, with low insertion and removal forces For automatic equipment,

  simplified automated wiring machines.

  Various other features of the invention

  moreover emerge from the detailed description which follows.

  An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawings. Fig 1 shows the contact panel to be connected to a programmer. Fig 2 shows the upper fixing plate of the programmer as a partial part, shown

following section A-A of fig 1.

  Fig 3 is a group sheet inserted and

  connected, shown along section B-B in Fig 1.

  According to fig 1, a programmer of a dishwashing machine equipped with four program disks has a contact panel in twenty four parts, which is divided into six vertical rows for a total of six pieces of cards of indivisible groups 11 which can be connected directly By group card 11, four scheduler contacts are thus simply occupied, one above the other and, as a result, the plugging and unplugging forces are kept low Numerical references 1 , la, lb up to 8, 8 a, 8 b designate each of the programmer contacts (Programmer contacts 2,4, 6, 8 are occupied by the first group card, contacts 2 a, 4 a, 6 a, 8 a by the second group plug, etc.) On the programmer box are arranged, each time, an upper fixing plate 9 projecting above the contact panel and a fixing plate

lower 10 (fig 2 and fig 3).

  The fixing plates 9, 10 of the programmer are used simultaneously to receive group cards 11 placed one beside the other Each group card It has, at the bottom and at the top, notches 12 and coded bars 13 (fig 3) The locking notches 12, located at the top, are molded with elastic locking levers 14, which hold the group plugs 11 to prevent them from coming out involuntarily, namely ensuring their positioning (fig 3) Each of the group plugs 11 are non-polarized by means of their locking notches 12, locking levers 14 and coded bars 13 and can be inserted to measure in the corresponding snap-in notches 15 and in the coded slots 16 of the plates

upper and lower 9, 10.

  The modification in accordance with the invention of a programmer boot in the form of fixing plates 9, 10, drilled, namely split in staggered rows relative to one another, thus allows without the intervention of distribution devices and guiding grids, direct connection and obligatory correct connection of the plugs

group 11.
