Definitions

  • the invention relates to a press-fit connector, in which a pin-like contact element is held in an insulating plastic body, said contact element having a projecting press-fit contact region on the pinside.
  • Multipole press-fit connectors for example such connectors with 48 or 96 contact pins arranged closely spaced in several rows in the manner of a matrix, which are used to establish a plugable connection in predrilled and through-plated holes of a printed circuit board, are known.
  • the so-called C-PRESS® contact has become known in particular, this contact ensuring by its resiliently yielding contact region good contact-making with substantially uniform bearing pressure over the entire contact region of a contact hole.
  • the pressing-in of such press-fit connectors has generally required a tool which engages in the plug housing via an opening running parallel to the contact element and presses on a press-in shoulder formed on the contact element and lying inside the plug housing.
  • the tool may also be shaped such that pressure is applied at the same time to the upper surface of the insulating plug housing. If simply a flat tool is provided for the pressing-in operation, it is essential that the metallic contact elements contact the insulating plug body over sufficiently large areas in order to be able to transfer the required forces.
  • Such a large-area anchoring of the contact element inside the insulating body is, however, at odds with the wish for ever greater miniaturization of such connectors. In spite of the large-area anchoring of the contact elements in the insulating body, rupturing of the plug housing, with the consequence of corresponding projection not only of plug material but occasionally also of (usually already loaded) circuit boards, occurs nevertheless.
  • EP-A-0 065 146 discloses a preassembled press fit connector comprising a connector housing and first and second adjacent rows of contacts mounted within the housing. Each contact has a press shoulder portion within the housing and a press fit section extending downwardly below of the housing.
  • a removable insert includes a plate portion for defining an external connector press surface above the housing and first and second rows of integral teeth extending downwardly into the housing. The rows of teeth engage one each with the press shoulder portions of the first and second row of contacts. This allows the press fit sections of the contacts to be simultaneously forced into mating engagement with the plated thru holes of the printed circuit board by applying pressure to the connector press surface.
  • Such a press fit connector offers the advantage of having a metal - to - metal contact between a pressing-in tool and the contact element.
  • the invention is consequently based on the object of improving a multipole press-fit connector with pin-like contact elements in such a way that rupturing of the insulating plug body during the pressing-in operation can be ruled out.
  • the invention provides that, for even force transfer of the pressing-in force onto the contact element, at least one section of the contact element anchored in the plastic body and running in the longitudinal direction extends right through as far as the surface of the plastic body opposite the press-fit contact region and terminated preferably flush with the surface of the plastic body.
  • the measure according to the invention of taking one or more longitudinally extending sections of the contact element right through as far as the upper surface of the insulating part of the plug housing, on which the pressing-in tool is brought to bear provides the advantage that pressing-in can now be performed with a simple flat type of pressing-in tool, without there being the risk of rupturing the insulating body, because the pressing-in force is transferred over a surface area and evenly.
  • the single figure shows a single contact in an insulating body, i.e. the plug housing holding a multiplicity of contact elements.
  • a pin-like contact element 2 is shaped in the example represented as a so-called C-PRESS® contact having a crescent-formed or C-formed press-in zone 4, which in the longitudinal extent follows on from a lower conically running insertion region 8.
  • the contact element 2 is anchored in an insulating body 1 (represented diagrammatically in the drawing) together with a multiplicity of contact elements of the same type (not shown).
  • the press-in zone 4 goes over into two vertically running limbs 6, which are connected to each other at the rear by means of a region 3. This region 3 bears the contact spring 5.
  • sections of the contact element running in the longitudinal direction, in the given example the limbs 6, are taken through as far as the upper surface of the insulating body 1 and terminate at the surface (shown cross-hatched) flush (cross-sectional area 7) with the upper surface of the insulating body 1.
  • a flat pressing-in tool is used.
  • the pressing-in force is now no longer transferred from the insulating body 1 onto the anchoring regions of the respective contact element, that is to say indirectly, but, by virtue of the flush cross-sectional areas 7, directly onto the contact element.
  • ruptures and deformations of the insulating body 1 of the plug housing and deformations of the individual contact elements during the pressing-in operation are avoided.
  • the force transfer takes place directly from metal to metal.
