Definitions

  • the invention pertains to a connector comprising a header and a receptacle, each comprising a housing provided with at least one contact element and with a conductive coating which, at least upon mating, forms a shield, which shield is connected or connectable to a ground contact or electrode, wherein the header and/or the receptacle comprises a spring contact attached to its conductive coating parallel to the surface of the housing, which spring contact serves, upon mating of the header and the receptacle, to establish an electrical connection between the respective conductive coatings.
  • the invention aims to provide a connector of the above mentioned type which does not exhibit the said disadvantage, or wherein the said disadvantage is at least substantially reduced.
  • the invention is characterised in that the spring contact is further attached to a protrusion or a recess respectively on or in the housing.
  • At least part of the surface of contact between the spring contact and the housing builds an angle with that part of the spring contact that runs parallel to the housing, which angle is in excess of 45 degrees.
  • At least part of the surface of contact between the spring contact and the housing runs perpendicular or substantially perpendicular to that part of the spring contact that runs parallel to the housing.
  • the surface of contact between the spring contact and the housing comprises at least two parallel or substantially parallel parts, which build an angle, preferably of about 90 degrees, with that part of the spring contact that runs parallel to the housing.
  • an angle preferably of about 90 degrees
  • Fig. 1 shows a cross section of a connector comprising a spring contact in accordance with the prior art.
  • Fig. 2 shows the spring contact according to fig. 1 in more detail.
  • Fig. 3 shows a spring contact in accordance with the present invention.
  • Fig. 1 shows, on the left-hand side, a header 1, comprising a housing 2 which is attached to a substrate 3 and which is provided with five contact elements 4.
  • the housing 2 is made of plastic, e.g. a liquid crystalline polymer (LCP) or nylon (for example PA6), and has been provided with an electrically conductive metal coating (not shown).
  • LCP liquid crystalline polymer
  • nylon for example PA6
  • an electrically conductive metal coating (not shown).
  • Such coatings are known to the person skilled in the art, and may, for instance, comprise a copper layer with a thickness of say 1 - 2 ⁇ m on which a nickel or aluminium layer of say 2 - 3 ⁇ m has been deposited.
  • the metal coating on the housing 2 is electrically connected to a ground electrode (not shown).
  • Fig. 1 further shows a receptacle 5 which comprises a housing 6 in which five contact elements 7 are placed.
  • the housing 6 may be made of the same material as the housing 2 of the header 1 and has been provided with a similar electrically conductive metal coating.
  • a metal spring contact 8 has been attached which, upon mating of the header 1 and the receptacle 5, establishes an electrical and mechanical connection between the respective metal coatings.
  • Fig. 2 shows the spring contact 8 in more detail. It further shows a force F2, exerted on the spring contact 8 during the mating of the header 1 and the receptacle 5, and a force F1 exerted on the metal spring during and after mating.
  • the force F2 will mainly result in a shearing force at the surface of contact between the spring contact 8 and the housing 6, whereas the force F1 will result in a bending moment M and a peeling force at the said surface, which, in turn, will often result in failure of the connection between spring contact 8 and the metal coating on the housing 6.
  • Fig. 3 shows a metal spring contact 9 in accordance with the present invention.
  • This spring contact 9 is provided with a clamp or clip 10 with two parallel legs 11. Through these parallel legs 11 the spring contact 9 has been clamped on a countersunk protrusion 12 provided on the housing 6.
  • the spring contact 9 is firmly attached to the housing 6 and repeated mating an unmating of the header 1 and the receptacle 5 is made possible without endangering the integrity of the metal coating on the housing 6.
  • the spring contact 9 is preferably made of a metal, more specifically of a copper alloy such as phosphorus bronze or beryllium copper.
  • the protrusion or recess may be provided after the conductive coating has been applied to the housing, it is preferred that the protrusion or recess is provided beforehand so that the surface of the protrusion or recess is covered in its entirety by the conductive coating.
  • an amount of solder is applied so as to render the connection airtight or substantially airtight.
  • the present invention also relates to individual headers and receptacles for use in the connectors described hereinbefore.
  • the housing or the header and/or the receptacle may be an integral whole, obtained through e.g. injection moulding, but it may also be an assembly of two or more parts.
