Definitions

  • the invention relates to a plug contact, a method for producing such a plug contact and a connector system with such a plug contact.
  • Plug contacts e.g. Flat or round plug in connector interfaces or connector systems to which a socket contact or a mating connector to be plugged, are often coated with a contact surface.
  • the surface is coated in a plug-in portion of a plug-in contact designed as an electrical conductor with a noble metal.
  • coatings of tin (Sn) are also established in addition to noble metal coatings (for example with gold (Au) or silver (Ag)).
  • a plug contact with a coated surface to reduce the insertion force is from the DE 102 24 693 A1 known.
  • Silver may corrode or "tarnish" upon exposure to ambient air, eg through sulfur-containing compounds from the ambient air. This can lead to a clearly visible optical change (“start-up”). It is possible to protect (passivate) the contact surfaces with organic thiols (compounds with a -SH group). This passivation can block sulfur-containing compounds from entering the surface, thereby preventing reaction with the silver.
  • Organic (alkyl) thiols also have a very good lubricating effect, which significantly reduces the insertion forces of the socket contact on the plug contact or on the flat blade and a cold welding in derogation. This can also be used, for example, in gold-plated or coated with other metals ladders.
  • the thiols may e.g. as aliphatic hydrocarbons, linear aliphatic hydrocarbons, or as alkanes having a terminal thiol group instead of an H atom.
  • they can have self-organizing properties and form so-called self-assembled monolayers ("self-assembled monolayers", SAM).
  • the thiol group -SH at the end of a linear aliphatic hydrocarbon chain (e.g., C18H37-SH: "octadecylthiol” (ODT)) adsorbs on the silver surface because sulfur (S) and silver (Ag) have strong binding affinity.
  • the attached filamentary hydrocarbon chains align parallel to each other and perpendicular to the silver surface. This leads to a self-assembled monolayer of octadecylthiol (ODT), since the largest possible docking of sulfur via a thiol-metal bond to silver represents the most energetically favorable state.
  • Self-assembled ODT monolayers are formed by solutions or vapors of the ODT which precipitate on the silver surface with the terminal thiol terminus of the C18 hydrocarbon chain of the thread-like ODT molecule on the metallic silver surface. This creates a closed ODT monolayer.
  • the surface adsorption reduces the energy of the free silver surface.
  • the high binding energy of the chemisorbed thiol group to the silver stabilizes the resulting monolayer and the van der Waals interaction between the parallel arranged hydrocarbon chains leads to a dense packing, which in turn reduces the free energy of individual thread molecules. As a result, the densely packed ODT monolayer grows on the silver surface.
  • SAM self-assembled monolayers
  • the invention is based on the recognition that organic thiols can migrate or diffuse very strongly on the coated parts. These properties enable them to occupy the entire surface of the plug-in contact within a short time.
  • the presence of the organic material, in particular a SAM, on the electrical conductor in a connection section that represents a connection geometry to an electrical or electronic component may be undesirable. Because the frictional force-reducing properties of the SAM can e.g. cause the electrical connection of the connection portion to an electrical lead, e.g. is hampered by wire bonding (friction welding).
  • a selective application of the organic material with the thiol group only on the plug-in area of the conductor is indeed possible. Due to the migration or diffusion of the organic material and the endeavor to achieve an energy minimum, however, even with selective application after a short time, the connecting section may also be covered with a SAM.
  • a plug-in contact which, in the plug-in area, has a coating e.g. from a precious metal or tin or similar wherein the coating is covered by an organic material having a thiol group and, at the same time, preventing the organic material from advancing along the surface of the conductor to its connecting portion by a diffusion process over time.
  • a plug contact with an electrical conductor for insertion into a mating connector comprises a plug-in section for insertion along a plug-in direction into the mating plug.
  • the conductor further comprises a connecting portion facing away from the plug portion for electrically conductive connection to an electrical or electronic component.
  • the conductor further includes a barrier portion disposed along a direction of extension of the conductor between the plug portion and the connection portion.
  • the plug portion has on the surface a first coating of a noble metal or tin.
  • a second coating of a first material is applied to the first coating.
  • the first material is an organic material containing at least one thiol group.
  • the barrier section has a silver coating on the surface. On the silver coating of the barrier portion, a second material different from the first material is applied, which forms a chemical compound with the silver coating.
  • the silver coating of the barrier portion may be identical to the first coating of the male portion.
  • the conductor can be formed from the plug-in section into the barrier section and possibly even as far as the connection section with a uniform coating, which can be made of silver, for example.
  • the plug portion may also have a coating other than silver. In principle, even in the mating area a non-precious metal coating may be provided, e.g. made of tin.
  • the conductor may be formed, for example, as a metallic conductor. It may be formed, for example, in the manner of a contact blade or a contact pin. It may, for example, have an elongated extension.
  • An elongated extension means that along the direction of extent of the conductor at least five times, preferably at least ten times as long as in the extending transversely to the direction of extension dimensions.
  • the proposed plug-in contact advantageously has the effect that in the plug-in section the insertion forces are significantly reduced by the coating by means of the first material and, at the same time, depending on the coating material, corrosion or "tarnishing" of the first coating is prevented.
  • a migration process or Diffusion process of the organic material along the surface of the conductor from the plug portion to the connecting portion effectively interrupted.
  • the surface is chemically or electrochemically modified by the application of the second material such that the organic material in an energetic view there runs against a potential barrier, so that the migration process or diffusion process is prevented.
  • the electrochemical potential changes in such a way that at the given temperatures (in particular room temperature) the kinetic energy in connection with the energy gains due to a change of position to another position or to an electrochemically viewed other surface are no longer sufficient to cause the Barrier section with the changed there surface to overcome.
  • This advantageously has the effect that a defined surface is present in the connection section, on which, for example, a wire bond connection (ie a friction welding process) can be carried out without problems.
  • connection portion may have a coating which is particularly suitable for the connection process to be selected in order to complete this connection process e.g. to firmly connect a cable or an electric wire to the connecting portion.
  • the second material completely encloses the conductor in the barrier section.
  • the barrier portion of the second material may be circumferentially applied around the direction of extension of the conductor on the surface. It is crucial that there are no continuous paths between the male portion and the connecting portion, which do not lead across the barrier section.
  • a sublimation process can be used.
  • the plug contact may be brought to an elevated temperature (for example more than 50 ° C or more than 100 ° C).
  • the process may e.g. also take place under ambient conditions, e.g. even in the presence of water vapor in the air.
  • suitable conditions such reaction of the desired material, e.g. of iodine, sulfur, etc., with the silver coating done.
  • the barrier region extends along the direction of extension of the conductor over a length of at least 1 mm, preferably over a length of at least 2 mm and most preferably over a length of at least 3 mm. This advantageously ensures that even if some non-saturated silver atoms remain on the surface of the barrier section, migration or diffusion of the organic material from the plug-in section to the connection section is effectively prevented.
  • an electrical line is electrically conductively attached to the connecting portion.
  • the plug contact can be flexibly connected to an electrical or electronic component.
  • the electrical line is connected by a bond with the connecting portion.
  • the electrical lead may be implemented as an aluminum wire or as a gold wire.
  • Such a bond can be made on a large scale with a short cycle time without sacrificing e.g. to generate the temperature stress occurring in conventional welding.
  • the conductor is formed as a stamped and bent part.
  • the conductor or the plug contact can be provided, for example, as a contact blade in a flat design or as a contact pin in a round design.
  • the plug contact may be flat or have one or more kinks along its extension direction.
  • the conductor has an elongated extension.
  • the plug portion is disposed at a first end of the conductor.
  • the connecting section is arranged at a second end of the conductor remote from the first end.
  • the proposed method advantageously provides a plug-in contact which, on the one hand, can be plugged together with a mating plug in a particularly low-friction manner in the plug-in section.
  • the insertion force is particularly advantageously reduced by the coating with the first material.
  • the first coating may be protected against corrosion or "tarnishing" by the coating with the first material.
  • the coating of the barrier portion with the second material provides an electrochemical barrier against a migration process or a diffusion process of the first material from the plug portion to the connection portion. In this way, advantageously, the connectivity of the connection portion of the electrical conductor is maintained.
  • the connection section is thereby particularly advantageously in a defined state which, for example, enables reliable bonding by means of a wire bonding process.
  • an electrical connector system comprises a plug contact according to the above description, it further comprises a mating plug, in which the plug contact is plugged with its plug portion for establishing an electrical connection along a plug-in direction.
  • the electrical connector system further includes an electrical line which is electrically connected to the connecting portion of the plug-in contact.
  • the connection of the electrical line to the connecting portion may be a bonding connection, for example.
  • the electrical connector system advantageously has a particularly low insertion force when plugging or unplugging plug-in contact and mating connector. Furthermore, the connectivity between electrical line and connecting section is always in a defined state, so that, for example, a process-based bonding process is possible.
  • Fig. 1 shows an example of an electrical connector system 50, which comprises a plug contact 1, a mating connector 20 and an electrical line 10.
  • the plug-in contact 1 is inserted with a plug-in section 3 for producing an electrical connection in the mating connector 20.
  • the plug-in section 3 is electrically contacted, for example, with contact lamellae 21 or contact springs 21 arranged inside the mating connector 20.
  • the mating connector 20 is electrically connected to an electrical or electronic device 30 by means of a connecting line 31. This may be, for example, a control unit, an actuator or other components.
  • the plug contact 1 has an electrical conductor 2, which may be formed, for example, as a stamped and bent part.
  • the electrical conductor 2 may be a sheet metal part or a metal part.
  • the conductor 2 comprises a plug-in section 3 for insertion along an insertion direction E into the mating connector 20. It further comprises a connection section 4 facing away from the plug-in section 3 for electrically conductive connection to an electrical or electronic component 40.
  • the plug portion 3 is arranged at a first end 2a of the conductor 2, the connecting portion 4 is at a second end 2b of the conductor 2.
  • the second end 2b is remote from the first end 2a.
  • an electrical line 10 is electrically conductively connected to the plug contact 1 in the connecting section 4 or on the connecting section 4.
  • the connection of the electrical line 10 to the connecting section 4 can be represented, for example, by means of a bonding-wire connection.
  • a bonding wire for example, an aluminum wire or a gold wire can be used.
  • the electrical or electronic component 40 may be, for example, a control unit, a sensor, an actuator or another component. A training as a circuit board is possible.
  • a barrier section 5 is arranged between the plug-in section 3 and the connecting section 4.
  • the plug-in section 3 of the conductor 2 has on its surface a first coating 6 of a noble metal.
  • the first coating may be formed of gold, silver, platinum, palladium, etc.
  • a second coating 7 made of a first material 7a is applied to the first coating 6, that is, to the noble metal coating.
  • the first material 7a is an organic material which contains at least one thiol group (-SH).
  • the first material 7a is an aliphatic hydrocarbon, especially a linear aliphatic hydrocarbon. It can, for. Example, be an alkane having an SH group at one of its ends instead of an H atom.
  • the second coating of the first material 7a may be formed as a "self-assembled monolayer" (SAM). In other words, it is a self-organized monolayer of the molecules of the organic material. For example, this may be ODT (C18H37-SH). However, other materials having an SH group are also possible.
  • the barrier section 5 has a silver coating 8 on its surface. It should be understood that the silver coating 8 is disposed on the surface of the conductor 2. On the silver coating 8 of the barrier portion 5, a second material 9 different from the first material 7a is applied, which forms a chemical compound with the silver coating 8. In other words, the surface of the silver coating facing the outside environment is chemical or electrochemically modified. In the outer environment, therefore, no free ends of silver atoms are more directed, but the outward facing (chemical (ends of the silver coating compounds of silver assign.) This results in a completely different from the pure silver coating 8 electrochemical potential. In this way, a migration process or diffusion process of the first material 7a from the plug-in section 3 in the direction of the connection section 4 by means of the barrier section 5 is effectively prevented.
  • FIG. 2 shows in an enlarged view a plug contact 1 similar to the plug contact FIG. 1 , In contrast to the plug contact 1 off FIG. 1 is the plug contact 1 of FIG. 2 provided with two creases.
  • the illustrated schematic cross-section shows in the connecting portion 4, the bond of the electric wire 10 in more detail.
  • the plug-in section 3 is arranged at the first end 2a of the conductor (on the left in the figure).
  • the connecting portion 4 is arranged at the second end 2b of the conductor 2 (on the right in the figure).
  • the second end 2b is remote from the first end 2a.
  • the barrier section 5 is arranged in the figure between the two ends 2a, 2b.
  • the connecting section 4 has a third coating 4 a, which may be different from the first coating 6 of the plug-in section 3.
  • the third coating 4 a may, for example, be designed to optimize or simplify the bonding process for the electrical line 10. This surface may vary depending on the bonding wire (e.g., Al or Au or Cu) e.g. Comprise aluminum or nickel or a layer sequence of Cu / Pd / Au.
  • the SAM which represents the second coating 7 with the first material 7a, schematically shown elevated and lifted.
  • the first material consisting, for example, of C18H37-SH, by means of its thiol group, faces the first coating 6, which comprises a noble metal or also tin.
  • the alkane chain protrudes from the surface to the outside. Due to its kinetic energy and the energetic ratios of the surface energy of the first coating 6, the SAM is formed on the first coating 6 on its own.
  • the first coating 6 may comprise, for example, silver, gold, palladium, platinum, etc.
  • the first coating can also comprise tin or be formed from tin.
  • the second material 9 is applied to the silver coating 8, which is applied directly or indirectly to the electrical conductor 2. This saturates the otherwise assigning surface silver atoms and thereby causes a completely different electrochemical potential.
  • the barrier section 5 extends along the direction of extension of the conductor 2 (extension direction corresponds in this case to the insertion direction E) over a length L. This length L extends over at least 1 mm, preferably over at least 2 mm, very preferably over at least 3 mm. This takes into account the fact that the saturation of the surface assigning silver atoms may not be completely ensured by the second material 9.
  • the length L of the barrier section 5 effectively suppresses migration or diffusion of the first material 7a from the plug-in section 3 to the connection section 4.
  • the second material 9 covers the conductor 2 circumferentially. In other words, there is no path from the plug portion 3 to the connection portion 4, which does not extend beyond the barrier portion 5. This effectively prevents migration or migration or diffusion of the organic molecules of the first material 7a towards the connection section 4.
  • the second material 9 may, for example, be a compound of silver with at least one element from the 6th main group. Thus, it may be, for example, a compound of silver with oxygen, silver with sulfur, silver with selenium or silver with tellurium. Alternatively or additionally, the second material 9 may be a compound of silver with at least one element of the 7th main group, for example silver with chlorine or silver with fluorine or silver with iodine or silver with bromine.
