Definitions

  • the invention relates to an electrical plug connection with at least two contact partners that can be joined together in an electrically contacting manner.
  • Electrical plug-in connections for example consisting of a plug-in sleeve and a flat plug, or similarly constructed electrical plug-in connections can be found in large numbers in electrical appliances in the consumer goods industry, such as large and small household appliances, appliances of the so-called brown goods, or else in electrical appliances for home and handicraft needs or the like application. Due to the large number of electrical contacts between two plug-in contact partners used there, there is a not negligible risk that, especially in large-scale production, the electrical conductivity of the electrical plug-in contact partners joined together by plugging, for example due to contact partners lying outside of the manufacturing tolerance or otherwise faulty, the electrical conductivity between the merged contact partners are either not given at all or only insufficiently.
  • the invention has for its object to remedy the disadvantages of the prior art with simple design measures.
  • At least one of the contact partners is additionally provided with electrically conductive means which, at an at least largely predetermined temperature threshold, change to a liquid state and are at least partially guided into the overlap area between the contact partners and connect them in an electrically conductive manner ,
  • the melting point of the electrically conductive means used to establish the electrical connection between the contact partners can be selected differently, so that different heating at the interface between the two contact partners can be taken into account in a simple manner.
  • the measure according to the invention achieves a high quality standard of the products equipped with it, without having to carry out a 100% test or a selection test with regard to the electrical conductivity of the electrical contact partners assembled by plugging in as part of a quality assurance. Accordingly, the solution according to the invention makes a not insignificant contribution to the cost-effective production of electrical devices, the cost reduction particularly having an impact on electrical devices manufactured in large series, such as electrical household appliances or the like.
  • the means are particularly expedient, in particular with regard to their optimized use of materials, if, according to a preferred embodiment of the object of the invention, it is provided that the means in their liquid at temperatures below the destruction temperature of the contact partners and / or the connecting lines electrically contacted therewith Initial state are transferred.
  • the means are arranged at least as far as possible outside the overlap area of the two contact partners created by the joining.
  • Such an arrangement of the electrically conductive means not only ensures that the two plug contact partners can be joined together unhindered, but also offers the advantage that the amount of the electrical conductivity of the means to be produced can be increased within certain limits in order to always ensure that in the event of a fault and the associated increase in heat in the contacting area, sufficient electrically conductive agent, for example in the form of solder, can flow into the overlap area between the two contact partners to produce the electrical conductivity.
  • the agents are transported in the heated, liquefied aggregate state in the overlapping area.
  • the targeted, forced feeding of the electrically conductive means into the area provided for contacting the two plug contact partners ensures electrical contact between the two even after an originally existing fault.
  • the electrically conductive means can be supplied particularly securely and defined in the area provided for contacting the two contact partners if, according to a next advantageous embodiment of the subject matter of the invention, it is provided that the liquefied electrically conductive means at least through at least one channel at least approximately in the form of a capillary supported in the overlap area.
  • the contacting area between the two electrical plug-in partners is particularly reliably supplied with electrically conductive means in the event of a fault if, according to a next preferred embodiment of the subject matter of the invention, it is provided that a plurality of at least approximately capillary channels are provided, which are star-like in the overlapping area of the two Contact partners flow.
  • the capillaries are particularly simple to manufacture and therefore inexpensive to manufacture, if according to a further preferred embodiment of the object the invention provides that the capillary is formed by a recess in one of the contact partners and a wall covering the recess of the other contact partner.
  • the depression can be produced, for example, inexpensively by embossing in one production run with the production of the plug contact partners.
  • the conductive electrical means are particularly favorable if, according to a next preferred embodiment of the object of the invention, it is provided that the means are designed as solder.
  • the solder is particularly expedient with regard to the melting temperature of the solder and thus to the heating temperature of the two contact partners in the event of a fault, if according to a last preferred embodiment of the subject matter of the invention it is provided that the solder is designed as a soft solder.
  • FIG. 1 shows an electrical plug connection in the disassembled state, with a flat plug and a solder in the solid state in a plug receptacle receiving a solder reservoir, in a spatial view from above,
  • FIG. 3 shows the electrical connector in the assembled state, according to
  • FIG. 2 in the contacting area, in a view from above, cut according to the section line III - III, Figure 4 shows the electrical connector in the joined state in the
  • Figure 5 shows the electrical connector in the joined state according to
  • an electrical plug connection 10 is shown in the disassembled state with a plug-in sleeve 11, which in the present case has a flat profile.
  • the receptacle 11 has two line brackets 12 lying next to one another and rolled up to form a ring contour. These are used to fasten wire strands 13 which are in themselves plastic-coated and which are stripped at their free ends, so that their now freely accessible line wires 14 are essentially made by curling a contact opening 15 having a circular opening cross section can be fixed in an electrically conductive manner.
  • the plug-in sleeve 11 has a sleeve section 16 which has a support and guide section 17 with a flat cross-section.
  • Two channel-like depressions 18 produced by cutting the guide section 17 without cutting are introduced into them (see FIGS. 3 and 5). These are arranged symmetrically to an axis of symmetry S serving as a center line for the guide section 17 and in the present case have approximately 2/3 of the length of the guide section 17, one end of the channel-like depressions 18 on the lateral edges of the end of the receptacles 15 facing Guide section 17 is seated, while the other end of the depressions 18 to be run toward one another in the direction of the axis of symmetry S.
  • the guide section 17 carries holding and receiving sections 19, which are integrally formed on the guide section 17 and are formed by rolling in flat-profile projections arranged on both sides of the guide section 17.
  • the holding and receiving sections 19 have a circular cross section in the rolled-up state, their free, against the bearing surface of the Guide section 17 directed end 20 end at a distance a above the support and guide surface of the guide section 17.
  • the holding and receiving sections 19 have at their end section facing the receptacles 15 a reservoir 21, the electrically conductive means 22 in the solid state, such as solder based on soft solder DIN 1707 or DIN 1732 based on tin or according to DIN 1732 and 1735 based on silver.
  • the plug-in sleeve 11 with its guide section 17 serves to receive a flat plug 23 which can be inserted into the guide section 17 in the direction of arrow I.
  • Flat plug 23 is of flat profile in cross section and has an essentially adapted to the length of the guide section 17 plug section 24, the height h in the correct manufacturing state of the socket 11 and the flat plug 23 at least approximately to the distance a between the free ends 20 of the support and Guide surface of the guide section 17 is adapted.
  • the plug-in sleeve 11 and the flat plug 23 form an overlap region X in the joining state, due to the lengthwise matching of the plug-in section 24 to the guide section 17, in which the groove-like depressions 18 lie at least with the essential part of their length.
  • the channel-like depressions 18 form capillary-like channels together with the underside of the plug-in section 24 which is at least largely flat and faces them.
  • the opening cross section of these capillary channels is matched to the viscosity of the electrically conductive means in the liquid state of aggregation, in order to bring about a kind of automatic transport movement for them within the capillary lengths to the overlap region X.
  • the solder stored within the reservoir 21 is converted into the liquid state of aggregation and through the channels 18 formed in the manner of capillaries into the overlap region X between the plug section 24 and the Guide section 17 out.
  • the solder By transporting the solder into the overlap area between the flat plug 23 and the plug-in sleeve 11, these two components are connected to one another in an electrically conductive manner by the electrically conductive solder, as a result of which the contact resistance decreases and these two components cool down increasingly, so that the solder in turn becomes liquid in its transferred physical state and the electrical connection between the components 11 and 23 is permanently established.
