  • the high-current socket is inserted into a recess of an insulating housing surrounding the high-current socket or in the body of the housing and usually set therein.
  • the high-current socket through the Opening the recess introduced into this and z. B. attached via a locking connection.
  • the high-power socket is divided into three sections, which are integrally formed with each other in the manufacture of the high-current socket.
  • the first section is a contact section at which the actual electrical connection is made with another plug / pin.
  • the contact portion consists of several, in particular resilient, tongues between which the pin is inserted.
  • the second portion is the intermediate portion on which elastic spring tongues are formed to allow the locking connection described above in the surrounding housing.
  • the third section is the fastening section with which the high-current socket can be fastened to other components.
  • Such a high current socket in the form of an electrical terminal is from the DE 2 227 204 A1 known.
  • the mounting portion of this electrical terminal is designed for crimping with an electrical cable.
  • the high-power bushes are punched out of a flat metal plate, wherein the punching already takes place in the later desired shape of the high-current socket.
  • Suitable metallic materials which conduct the current well are known to the person skilled in the art.

Furthermore, mounting legs are provided on the mounting portion, with which the high-current socket can be fastened to a further base. In the interior of the recess of the housing, which surrounds this high-current socket, elongated centering guide elements are formed integrally with the housing, with which a guidance of the contact tongues of the contact section takes place in the recess. Furthermore, locking projections are formed in the recess, which with Coupling locking tongues on the high-current socket to secure them in the housing. A determination in the axial longitudinal extent of the cavity bushing relative to the housing takes place here only in a longitudinal direction. The too wide insertion of the cavity bushing in the housing is not avoided here.
  • the skilled artisan has the object to improve an electrical connector with a housing and a high-power socket to the effect that the production of the high-current socket and in particular the contact tongues simplifies avoiding damage to the contact tongues when inserted into the housing and the Alignment in the longitudinal extent of the high-current socket relative to the housing in the desired position can be fixed.
  • the core idea of the invention is that a guidance / alignment of the high-current bushing relative to the housing does not take place with guide devices in the interior of the recess, but with guide devices which are arranged in the region of the opening of the recess, in particular outside / in front of the recess.
  • This avoids that the resilient contact tongues are bent in an incorrect insertion of the high current socket in the recess by the guide means arranged therein and thus the high-current socket or the entire connector are unusable.
  • the contact tongues in the recess are arranged already in the region of the opening of the recess in the housing of the electrical connector guide means the contact tongues in the recess, during further insertion, already arranged in the correct position.
  • the resilient tongues at the intermediate section are preferably obtained by a flat embossing in order to obtain a stepless reduction of the cross section and thus a better spring action.
  • the high-power bushing or the material blank from which the high-power bushing is made is designed such that the material thickness of the fastening portion is greater than the material thicknesses of Intermediate and the contact sections.
  • this stage serves as a stop surface, which cooperates with a counter-stop surface in the recess of the housing of the electrical connector.
  • the high-current socket can only be pushed into the recess in the body of the housing until the respective abutment surfaces lie directly against one another.
  • the high-current socket can be fixed in the desired position in the axial direction in the housing. This means that the depth at which the high-current socket is inserted into the housing is desirably selectable and adjustable.

  • a recess is provided, into which through the opening of the recess, the high-current socket is inserted.
  • locking projections are formed in a conventional manner, which cooperate with the spring tongues described above at the intermediate portion of the high-current bushing to avoid that the high-current bushing can be pulled out of the recess again.
  • guide grooves are formed on the housing in the region of the opening in the housing, into which correspondingly formed guide projections of the high-current bushes can be brought into engagement, so that the high-current bushing is in the correct position even before the insertion of the contact tongues into the recess is aligned and bending of the reeds is avoided.
  • the body has a counter stop surface, which cooperates with the abutment surface on the high current bush, which is formed by the change in the material thickness of the high power jack, to the depth at which the High current socket is inserted into the recess, limit.
  • the axial position of the high-current bushing in the housing can be fixed in the desired manner.
  • the housing itself is about other fastening devices, such. B. press-fit, with other components such as, inter alia, circuit boards or boards connectable.
  • the high-current socket is formed as described above, ie it has a guide projection on the attachment portion, with which the high-power socket is aligned in the correct position to the recess in the body of the housing. Further, at the transition from the intermediate portion to the fixing portion, a step-like increase in the material thickness of the blank from which the high-current bush is obtained is formed. This stage serves as a stop surface, which cooperates with the counter stop surface described above in the housing. Such a stage in the material blank can, for. Example be obtained by a material blank in the thickness of the mounting portion in the areas that form the later intermediate and contact portions, is reduced by a milling in its material thickness. Subsequently, the punching process and the forming process can take place.
  • the contact tongues are formed straight or rectilinear over their respective longitudinal extent, which means that they have no kinks or curves seen in the longitudinal direction, so that their production is possible by a single deformation of a flat material blank to a high-power socket.
  • a plurality of guide projections are formed on the attachment portion, for. B. two, which are formed on opposite sides of the mounting portion.
  • a corresponding configuration of the housing with a corresponding number and arrangement of the guide grooves is then also advantageous.

  • the fastening device can be configured as an SMD contact region.
  • the contact tongues are inclined toward each other towards its free end, so that the inside width of the cavity bushing is reduced towards the free end. This allows the electric pin to be clamped.
  • This inclination is either predetermined during the production of the cavity bushing by appropriate forming processes or is obtained by a correspondingly formed recess in the body of the housing, whose cross section is reduced.
