Definitions
- the invention relates to a plug connection for producing a moisture-tight electrical transition from a solid connecting wire to an electrical contact or contact element.
- the electrically operated or electrically connected components are connected via cables and plug connections, ie plugs and receptacles and the like.
- plug connections ie plugs and receptacles and the like.
- a relatively high amount of production and assembly work often has to be accepted.
- at least a multiple Disconnection and reconnection for maintenance, troubleshooting and the like is required.
- the present invention is therefore based on the object of providing a plug connection which is suitable for such applications and can be detached and restored at least a few times, which resists moisture and dirt, which is reliable, mechanically and electrically loadable and which is characterized by particularly low manufacturing and assembly costs .
- the special feature of the plug connection is that it has a receiving and guide sleeve which receives the connecting wire and which ends in an intended for filling with a permanently elastic, sticky potting compound and serving as a reservoir for this potting compound, and from a holding element exists, in which the wire tip is inserted when inserted into the sleeve through a previously closed, penetrable film or through a thin wall of another type.
- the holding element is in the form of a plug-in terminal, a solder socket or the like, which produces the electrical contact between the connecting wire and the contact body.
- the lead wire is conveniently insulated, i.e. with the insulating sleeve surrounding the metal wire, through the correspondingly dimensioned sleeve, through the extension and the penetrable film through to the holding element, in which the stripped tip of the wire is then contacted.
- the sleeve can be equipped with a "scraper funnel" or the like at the transition to the extension.
- the plug connection according to the invention is particularly suitable for connecting a consumer to a circuit board which is applied to a flat heat sink (generally an aluminum or a copper plate), the sleeve being seated on the heat sink side and the holding element on the circuit board side, and the connecting wire being through corresponding recesses are inserted in the cooling plate and in the circuit board.
- a flat heat sink generally an aluminum or a copper plate
- extension in which the sleeve ends in the form of a recess on the outlet side of the sleeve and to fill it with the casting compound via a separate filler opening or via a filler channel.
- the receiving and guide sleeve is closed with a puncture membrane on the outlet side of the inserted connecting wire.
- this mass then accumulates in the area of this membrane and in the adjacent extension.
- the elastic casting compound seals the passage surface.
- FIG. 1 in longitudinal section and schematically simplified components of a connector of the type according to the invention and their arrangement on the heat sink and the circuit board of the circuit board of an electronic controller
- Fig. 2 shows a schematic representation of a controller or a complete unit in which the connector of Fig. 1 is used and
- Fig. 3 shows a schematic representation of the formation and filling of a receiving and guide sleeve for an embodiment of the invention.
- Fig. 1 illustrates the most important components of a plug connection according to the invention before inserting a connecting wire 1.
- the wire 1 is used for contacting or for establishing an electrically conductive connection between a consumer (not shown) to which the connecting wire 1 in conventionally (or by a further plug connection of the type according to the invention), and the components or conductor tracks on a printed circuit board 2, which is part of a printed circuit board 3 of an electronic controller.
- the entire circuit board, which is shown in section in Fig. 1, consists of a flat heat sink 4, e.g. an aluminum plate, and the printed circuit board 2 together, which carries electrical, symbolically indicated components 5, 6 (transistors, capacitors, etc.) and contains conductor tracks (not shown).
- the printed circuit board 2 and the heat sink 4 are connected to one another by a thin, if necessary multi-layer adhesive film 7.
- the connecting wire 1 is inserted into a receiving and guide sleeve 8 of the plug connection according to the invention during an assembly or manufacturing process.
- the wire 1 provided with an insulation sleeve 9 is passed through the sleeve 8, passes through a free space or an extension 10 and through the adhesive film 7 through which the wire 1 pierces, into a holding element 11, which here is in the form of a symbolically illustrated plug-in terminal is.
- the plug-in terminal 11 naturally only takes up the stripped, front part, namely the tip 24 of the connecting wire 1.
- openings 12, 13 are provided, through which the connecting wire 1 reaches the plug-in terminal 11.
- constriction 23 in the form of an elastic lip or a corresponding membrane part, which forms a "scraper funnel” or the like and thereby the closing and Sealing of the passage opening after loosening the connector favors.
- the free space or the extension 10, which is provided for filling with a permanently elastic, sticky casting compound, is particularly important for the function of the plug-in connection according to the invention.
- potting compounds are e.g. known as SILGEL (Sil Gel 611 from Wacker Chemie Burghausen) and are e.g. used to seal copper wire bushings through printed circuit boards - see Figure 2.
- the inner diameter of the sleeve 8 is matched to the outer diameter of the wire 1.
- the plug connection namely the connection between the connecting wire 1 and the other components of the plug connection is detachable.
- the permanently elastic, sticky sealing compound VM which is located in the extension 10, closes the passage surface of the wire 1.
- the connection to the printed circuit board 3 remains tight. This is important to e.g. to prevent in the workshop that moisture can reach the populated side of the printed circuit board 2 through the openings 12, 13.
- Fig. 2 shows an application example of the connector according to the invention. It is a controller 14 for an anti-lock vehicle brake system.
- the controller contains, in a closed housing, a printed circuit board consisting of carrier plate or heat sink 4 'and printed circuit board 2' and equipped with electronic components 5 ', which are connected to a plurality of valve coils 16 via connecting wires 15 or connecting wires 15 shown in broken lines.
- the passage openings of the wires 15 through the heat sink 4 ' are, as indicated, enclosed in a liquid-tight manner with a permanently elastic, sticky potting compound VM, with which the extension 10' of the plug connection according to the invention is also filled.
- a hydraulic pump 17 is electrically connected to the controller 14.
- the pump 17 is equipped with solid connecting wires - only one connecting wire 1 'is shown.
- the pump 17 is placed on the housing, the connecting wire 1 'being inserted through the receiving and guide sleeve 8' becomes.
- the dashed border 18 in FIG. 2 contains the plug connection shown on a larger scale in FIG. 1 and previously explained.
- Potting compounds such as SILGEL are poured into the area to be sealed, in particular in the opening or extension 10, 10 'at the outlet end of the wire 1, 1' of the sleeve 8, 8 'in the thin-liquid state.
- Fig. 3 illustrates a schematic representation of an embodiment of the invention, in which the connecting wire 1 inserted through a receiving and guide sleeve 19 is sealed by the permanently elastic casting compound VM in the outlet area from the sleeve 19.
- a sleeve 19 is used, which is sealed with a puncture membrane 20 on the outlet side 20 of the sleeve 1 before the connecting wire 1 is inserted.
- An extension 21 in the form of an open filler channel 22 or the like is again provided near the outlet side, into which the initially low-viscosity potting compound VM, as symbolically shown in FIG. 3, is filled during the assembly of the regulator.
- This mass VM collects in the extension 21, which absorbs the permanently elastic, sticky mass VM when the wire 1 is inserted.
