Definitions

  • the invention relates to a connector arrangement for an electrical device, in particular a thermostatic controller, with a base part made of insulating material, on which laterally projecting at least two flat, broadly side by side spaced apart in a common plane, electrically conductive contact members are arranged.
  • thermostatic controllers it is common (DE-OS 27 24 527) to arrange the snap switch or switches on a ceramic base and to connect the switch contacts to contact members, which are of the type of the usual flat plug (6.3 x 0.8 mm DIN 46 244 ) are formed and attached to the ceramic base. Since at least two, usually three or more such flat plugs are required for the electrical connection, a corresponding number of differently shaped sheet metal parts, which generally consist of 0.8 mm MS sheet metal, are produced during manufacture to be punched. The manufacture and assembly of these parts on the ceramic base are therefore relatively complex.
  • the object of the invention is therefore to provide a connector arrangement for an electrical device, in particular a thermostatic controller, which is characterized on the one hand by a simple, closely tolerated possibility of manufacturing and installing the contact elements, and on the other hand allows a mechanical connection of a flat plug plug-in coupling part, without having to resort to the printed circuit boards contacted at the end or their own adapters.
  • the connector arrangement mentioned at the outset is characterized in that a flat cover cap made of insulating material is pushed onto the contact members, by means of which the contact members are covered, at least broadly, up to predetermined contact surface areas which are limited by corresponding wall openings in the cover cap and in that the Wall openings are arranged in a connector part of the cover cap which is set up to plug in an associated plug-in coupling part containing separate contact elements in a configuration and position corresponding to the arrangement and dimensions of the contact elements coming into contact with the contact surfaces.
  • the strip-like connecting part for attaching a plug-in coupling part suitable for lateral connection to circuit board contacts has dimensions j and the wall openings are narrow parallel parallel slots designed and distributed according to the contact elements.
  • the contact members can have a smaller thickness than the connecting part of the cover cap, which in practice means that the contact members can be punched out, for example, in the thickness of 0.8 mm standardized for flat plugs according to DIN 46 244, without having to connect one for the end Contacted printed circuit boards equipped flat plug coupling parts additional metal supports or the like. would be required.
  • the strip-like connector has the required thickness for the connection of the plug-in coupling part of 1.5 mm, as is customary for printed circuit boards, so that a perfect fit of the plug-in coupling part on the connecting part of the cover cap and, at the same time, perfect contact with the contact members are ensured.
  • the contact members can be enclosed on all sides by the cover cap up to the contact surface areas, while the wall openings can also be formed only in one wall of the connection part of the cover cap, which results in similar conditions as when connecting the plug-in coupling part to a printed circuit board printed on one side.
  • the cover cap can have insulating webs between adjacent contact members and electrically isolating them from one another, which are made of plastic material on the one Cover cap are integrally formed.
  • the contact members can be curved and clamped frictionally or positively against adjacent wall parts of the cover cap, in order to ensure that the cover cap and therefore also the plugged onto it are firmly seated in a captive manner To ensure plug coupling part.
  • the cover cap can also be used directly for coding the line connection in that its wall openings are arranged in a distributed manner in accordance with a predetermined code.
  • This code determines which of the adjacent contact members are connected to electrical lines of the plug-in coupling part via assigned wall openings of the cover cap and which contact members remain insulated by the cover cap against the assigned contact elements of the plug-in coupling part.
  • At least one contact element can also be completely covered and insulated by the cover plate in the context of this coding, so that it is not electrically connected to a connecting line via the plug-in coupling part.
  • the cover cap one for mechanical handling and a tight fit of the plug-in coupling part
  • it may be appropriate that it has a molded base that is free of wall openings and with which it can be connected to the base part carrying the contact members.
  • the contact elements are parts of an initially one-piece stamped sheet metal part, which as a whole the base part is mounted and from which the contact members are formed after assembly by punching out predetermined intermediate pieces.
  • the contact members initially connected in the one-piece sheet metal stamped part have the relatively small tolerances of such a stamped part.
  • the assembly of this one sheet metal stamped part on the insulating base part is considerably easier compared to the assembly of three individual contact members, and on top of that the connected contact members cannot change their mutual position during assembly. It is only on the assembly line that the contact members are separated from one another by punching out the intermediate pieces, onto which only the cover cap then needs to be attached, in order for one in particular mechanical connection of a circuit board flat plug coupling part to create a suitable plug arrangement.
  • the one-piece sheet metal stamped part can be designed in such a way that differently designed contact members, in particular standard-compliant flat plugs (DIN 46 244, 46 248), can be formed by punching out differently designed intermediate pieces.
  • differently designed contact members in particular standard-compliant flat plugs (DIN 46 244, 46 248), can be formed by punching out differently designed intermediate pieces.
  • the thermostatic controller shown schematically in FIG. 3 has an essentially rectangular, plate-like, ceramic base part 1, on which an electrical snap switch 2 is arranged, the switching tongue of which is designated by 3 and which is fastened at 4 to the base part, 1.
  • the switching tongue 3 carries a contact piece 5, which can optionally engage an upper and a lower fixed contact, of which the upper contact is illustrated at 6 in FIG. 6.
  • the upper contact 6 is fastened to a cranked contact carrier arm 7, which in turn is formed on a flat part 8 which is riveted to the base part 1.
  • two flat contact tabs 9, 10 are fastened on the base part 1 at a distance, of which the contact tab 9 is connected at 4 to the snap switch 2 and the contact tab 10 cooperates with the contact piece 5 of the tongue 3 lower contact piece carries.
  • contact members in the form of flat plugs 11, 11a are formed, which lie in a common horizontal plane over the associated side edge of the Protruding base part 1.
  • the flat plug 11a is indicated by dashed lines in FIG. 3. It can be cut away if all that matters is an on-off function of the snap switch 2.
  • a sheet metal part 12 is fastened on the side opposite the flat plugs 11, 11a, which carries a transmission lever 14 which is pivotably mounted at 13, which acts on the switching tongue 3 at the other end and whose actuation takes place by means of a diaphragm socket 16, which on the Sheet metal part 12 is arranged below the transmission lever 14.
  • the membrane box 16 is connected via a capillary tube 17 to a temperature sensor, not shown.
  • the contact tabs 9, 10 and the contact carrier arm 7, like the flat plugs 11, 11a, are parts of a one-piece stamped sheet metal part 18 before assembly, as shown in FIG. 1.
  • This stamped part is punched out of 0.5, 0.8 or 1.2 mm thick brass sheet in the outline shape according to FIG. 1 and pre-bent with the contact carrier arm 7 standing at a distance above the contact tab 10.
  • the sheet metal stamped part 18 is designed in such a way that, following the assembly state according to FIG. 2, the differently designed intermediate pieces, designated by 20 in FIG. 1 and shown in broken lines, can also be punched out from it by appropriate selection of the punching tools.
  • narrow contact members 21 connected to the two contact tabs 9, 10 and the flat part 8 are formed, which in the manner shown in FIG. 4 protrude from one another in a common horizontal plane at a distance from one another at an adjacent side edge of the base part 1.
  • a cover made of insulating plastic material 22 is pushed (Fig. 5,6), which has a substantially strip-like, parallel-flanked connection part 23 of rectangular cross-sectional shape.
  • the flat connecting part 23 is followed by a reinforced, also strip-like base 24, which is supported against corresponding shoulders 25 of the contact tabs 9, 10.
  • the flat connecting part 23 has a continuous thin, lower wall 26, to which two side walls 27 and a top wall 28 connect are connected to each other by an end wall 29 in such a way that the flat contact members 21 are enclosed on all sides by the plastic material of the cover cap 22. Between the adjacent contact members 21, there are integrally molded intermediate webs 30 in the cover cap 22, as can be seen from FIG. 6, which ensure the creepage and air gaps between adjacent contact members 21 required for the mutual electrical insulation.
  • the dimensions of the flat connecting part 23 are chosen such that a flat plug coupling part indicated at 33 in FIG. 5 can be plugged on and is held captively in the plugged-on state.
  • the flat plug coupling part 33 is a coupling part standardized for producing a plug connection in the case of printed circuit boards contacted on the edge, which carries resilient contact elements 34 arranged in a 5 mm grid, which are connected to the conductors of a ribbon cable 35 in a manner known per se.
  • the slot-like wall openings 31 are dimensioned and arranged in such a way that when the plug-in coupling part 33 is plugged onto the connecting part 23, the contact elements 34 thereof rest on the contact surface regions 32 of the contact members 21 and make electrical contact with them.
  • the cover cap 22 can be coded in the area of the connecting part 23 in that the wall openings 31 are arranged distributed according to a predetermined code. 5, this means that either all three wall openings 31 shown can be present or only two wall openings or even one wall opening - each in a different arrangement - can be present, whereby an electrical connection with the contact members 21 is only established in accordance with the predetermined code becomes. A further coding and at the same time a protection against rotation are made possible by the respective outer shape of the connecting part 23.
  • the base 24 of the cover cap 22 is then designed in the manner shown in FIG. 5 in such a way that the plug-in coupling part 33 is securely seated on the connecting part 23.
  • the contact elements 21 having a smaller thickness (0.8 mm) than the connecting part 23 (1.5 mm), as can be seen from FIG. 6, are slightly curved, so that there is a frictional jamming of the contact members 21 with the cover cap which has been pushed on 22 results.
  • a positive locking connection can be provided so that unintentional removal of the cover cap 22 is excluded.
  • the sheet-metal stamped part 18 is punched out of 0.8 mm brass sheet, then in the case of the regulator which is partially preassembled according to FIG. 2, either a plug arrangement with standard flat plugs 11, 11a can be selected by appropriately selecting the punching tools for the intermediate pieces 19 and 20 (Fig. 3) or a connector assembly with the contact members 21 shown in FIG. 4.
  • the contact members 21 are thinner than a printed circuit board (1.5 mm), but the thickness (1.5 mm) required for the connection of the flat plug coupling part 33 is produced according to a printed circuit board by the connecting part 23 of the cover cap 22.
  • the connector arrangement was described above using a temperature controller. It goes without saying that it can in principle also be used in a corresponding manner for other electrical devices in which the electrical line connection is made via flat plugs.
