Definitions

  • the invention relates to an electrical receptacle contact consisting of a contacting region for contacting a complementary contact blade and a connecting region for connection to an electrical conductor.
  • Electrical receptacle contacts are employed in plug connectors which are often used in systems with high vibrations, for example in the automotive industry.
  • FR 26 47 602-A1 discloses a one-part electrical receptacle contact consisting of a contacting region for contacting a complementary contact blade and a connecting region for connection to an electrical conductor.
  • the contacting region is box-shaped with a top wall and a bottom wall.
  • the contacting region comprises two parallel first contact spring tongues for contacting the complementary contact blade.
  • the top wall includes at least one first stamping which is oriented to extend into the box-shaped contacting region opposite the first contact spring tongues and serves for contacting the contact blade.
  • the bottom wall of the contacting region is of double-walled construction and additionally includes, above the contact spring tongues, a wall which serves as a stop for the contact spring tongues. Owing to the special design of the bottom wall, the material consumption for the production of this contact is relatively high. Moreover, it is disadvantageous that the contact blade is not introduced symmetrically into the centre of the receptacle contact. Further, it is disadvantageous that the contact blade is not securely guided within the receptacle contact and, for example, slight rotary movements of the contact blade are possible.
  • DE 43 42 363-A1 discloses a latching pluggable connection which has a similar construction. Instead of a contact blade, in this case there is provided a cable end sleeve which is protected in the receptacle contact against rotation by two ears bent inward from the side walls. In this arrangement, it is likewise disadvantageous that no symmetrical guidance of the cable end sleeve in the receptacle contact is provided for.
  • a device having a contacting region for contacting a complementary contact blade and a connecting region for connection to an electrical conductor, the contacting region being of box-shaped design with a top wall and a bottom wall, and further the contacting region further including two parallel first contact spring tongues formed in the bottom wall, at least one first stamping in the top wall that is oriented into the box-shaped contact region for contacting the complementary contact blade and which lies opposite the first contact spring tongues, characterized in that a web is provided in the bottom wall between the first contact spring tongues and running parallel to the first contact spring tongues, and in that the web includes a second stamping which is oriented into the box-shaped contacting region and serves as a protection against overstressing for the first contact spring tongues.
  • a further object is the reliable contacting of a contact blade. Reliable contacting is to be ensured even when used in highly vibrating systems. This is achieved by providing a protection against overstressing of the first contact spring tongues, which are formed in the bottom wall of the contacting region and contact the contact blade.
  • the protection against overstressing is a web that is arranged between the first contact spring tongues and formed by a second stamping which is oriented into the box-shaped contacting region to serve as a stop for a mating contact blade.
  • a complementary contact blade is received symmetrically in the receptacle contact. This means that the distance of the contact blade from opposite outer walls of the contacting region is in each case the same. This is achieved as the receptacle contact has on the top side, a contacting surface for the contact blade and has on the bottom side, opposed first contact spring tongues. By means of which, a central location of the contact blade between the top wall and the bottom wall is achieved.
  • the symmetrical arrangement achieves the effect that the receptacle contact can be inserted into a contact chamber even when rotated through 180°.
  • the electrical receptacle contact according to the invention can be latched in a housing. This is achieved by a latching spring tongue that is provided in the top wall and in the bottom wall. As the receptacle contact is inserted into a chamber of a housing, these latching spring tongues engage behind corresponding shoulders of the chamber and the receptacle contact is prevented from being pulled out.
  • guidance of the contact blade is provided for.
  • a fourth stamping in the side walls which serves for guidance and lateral contacting of the contact blade.
  • the side walls may also comprise second contact spring tongues, which serve for lateral contacting or guidance of the contact blade.
  • the latching spring tongues are protected against catching and against the penetration of foreign bodies between the free end of the latching spring tongue and the box-shaped contacting region.
  • This is achieved by two opposite ears oriented perpendicular to the direction of insertion that are provided in each case in the top wall and in the bottom wall.
  • the ears are bent perpendicularly out of the top wall and the bottom wall and correspond in their height to the height of the free end of the latching spring tongues.
  • the ears are arranged in the region of the free end of the latching spring tongues.
  • a secondary locking is also made possible.
  • the secondary locking of the electrical contact is achieved by a corresponding secondary-locking element that is provided in a corresponding chamber that engages behind the ears, which at the same time can serve to protect the latching spring tongues.
  • the contact can be produced in one part so that optimized material consumption can thereby be achieved.
  • a receptacle contact according to the invention is shown a one-part electrical receptacle contact 1 for receiving a complementary contact blade (not shown).
  • the receptacle contact 1 is made from a metal sheet by punching, stamping and bending. It is designed for use in a plastic connector housing (not shown) with contact chambers and to be secured in this chamber in a latched manner.
  • the receptacle contact 1 comprises a contacting region 2 for contacting the complementary contact blade and a connecting region 3 for connection to an electrical conductor (not shown).
  • the connecting region 3 is designed as a crimping region. It consists of a first crimping region 4 which is of U-shaped design in cross-section and a second crimping region 5 which is likewise of U-shaped design in cross-section, as illustrated in Figures 3 and 4.
  • the second crimping region 5 serves for fastening the insulation of the electrical conductor to be contacted, while the first crimping region 4 serves for contacting the electrical conductor.
  • the contacting region 2 may also be combined with differently designed connecting regions 3 which employ, for example, the insulation displacement contact method of termination.
  • the features of the electrical receptacle contact 1 according to the invention relate to the contacting region 2.
  • the contacting region 2 is a box-shaped design having two side walls 6, 7, a top wall 8 and a bottom wall 9.
  • the top wall 8 consists of two top-wall parts.
  • In the top wall 8 there is a seam 10, at which the two top-wall parts butt against one another.
  • the top-wall parts are connected to one another by means of welding spots 11.
  • a first stamping 12 oriented into the box-shaped contacting region 2.
  • the first stamping 12 is divided into two parts by the seam 10.
  • the first stamping 12 serves for contacting the contact blade.
  • the contact spring tongues 13 are joined to the box-shaped contacting region 2 at the front-face-side end and comprise ends 14 which are free towards the conductor-side end of the contacting region. Between the first contact spring tongues 13 there is a web 15. The web 15 is produced by a second stamping 16 which is oriented into the box-shaped contacting region 2 and is designed as a protection against overstressing for the first contact spring tongues 13.
  • the contacting region 2 comprises a second contact spring tongue 17 in each of the side walls 6, 7.
  • the contact spring tongues 17 are likewise oriented with their free ends towards the cable-side end 3 of the contact.
  • fourth stampings 18 may be provided in the side walls 6, 7 which likewise serve for contacting the complementary contact blade. It is also possible, however, for the fourth stampings 18 and/or the second contact spring tongues 17 to serve not only for contacting the contact blade but also for aligning the contact blade between the side walls 6, 7 of the receptacle contact 1.
  • the receptacle contact 1 comprises a latching spring tongue 19 on the top and bottom wall 8, 9, for retaining the receptacle contact 1 in a chamber of a connector housing. The so-called first contact securing is thereby performed. Further, the receptacle contact 1 comprises two opposing ears 20 oriented perpendicular to the direction of contact insertion in the top wall 8 and in the bottom wall 9. The ears 20 are bent substantially perpendicularly out of the top and bottom wall 8, 9.
  • the ears 20 serve to protect the latching spring tongues 19 in order, for example, to prevent a cable, for example, from being able to engage under the free end of the latching spring tongues 19.
  • the ears 20 can at the same time cooperate with a secondary locking mechanism of a housing for receiving the receptacle contact. For example, this could be a slide that engages behind the ears 20 in one position and removal of the receptacle contact is only possible if the slide is put into a second position.
  • the third stamping 21 is arranged in the top and bottom wall 8, 9. This third stamping 21 achieves the effect that a contact blade to be inserted into the receptacle contact 1 is precisely guided, thereby ensuring a rotary movement of the contact blade is not possible.
  • the box-shaped contacting region 2 has a particularly high structural stability by a circumferential completely closed band 24 which in each case, at its front-side end 22 and at its cable-side end 23, is joined to the connecting region 3.
  • the band 24 being closed by a welding spot 11.
  • the advantages of the above-described receptacle contact will be mentioned once again. It is of particular advantage that particularly good utilisation of material is achieved. It is advantageous that reliable electrical engagement of a contact blade is obtained. It is further of particular advantage that a complementary contact blade is received symmetrically in the receptacle contact. It is further of particular advantage that the one-part electrical receptacle contact according to the invention can be latched in a housing. It is further of particular advantage that rotation and looseness of the contact blade in the receptacle contact is avoided. It is further of particular advantage that a guidance of the contact blade in relation to the side walls is provided for. It is further of particular advantage that an additional lead-in funnel is not required at the insertion-face-side end of the contact.
  • latching spring tongues are protected against catching and against the penetration of foreign bodies between the free end of the latching spring tongue and the box-shaped contacting region. It is further of particular advantage that, besides the primary locking of the contact in a housing by means of the latching spring tongues, a secondary locking is also possible.
