Definitions

  • Connector assembly The present invention relates to a connector assembly accord ⁇ ing to claim 1.
  • Connector assemblies for disconnecting electric circuits carrying high currents and medium voltages in the range of 1 kV to 70 kV during installation and service conditions are known in the state of the art.
  • the EP 0 147 979 Bl describes a con ⁇ nector assembly that allows to disconnect an electric circuit without moving a cable. It is known to provide such contact assemblies with spring contacts which provide separable elec- trie connections. Such contacts are expensive to produce in order to provide reliable electrical connections over a long lifetime and a high number of switch cycles.
  • Mating metal parts usually require surface platings such as silver plat ⁇ ings .
  • a connector assembly comprises a cable terminal having a contact ring, an inner plug having a contact section and an outer plug being movable in a longitu ⁇ dinal direction.
  • the contact section can be clamped between the outer plug and the contact ring.
  • clamping the contact section of the inner plug between the outer plug and the contact ring may ensure a defined contact pressure between a contact section of the inner plug and the contact ring of the cable terminal which provides a defined and reli ⁇ able electric connection between the contact ring of the ca ⁇ ble terminal and the contact section of the inner plug.
  • the contact ring comprises a first screw thread.
  • the outer plug comprises a second screw thread mating the first screw thread.
  • the first screw thread of the contact ring and the screw thread of the outer plug allow to screw the outer plug into the contact ring of the cable terminal to move the outer plug in the lon ⁇ gitudinal direction. Screwing the outer plug into the contact ring of the cable terminal thus allows to clamp the contact section of the inner plug between the outer plug and the contact ring.
  • this allows to adjust a contact pressure between the contact section of the inner plug and the contact ring of the cable terminal.
  • the first screw thread is an internal screw thread and the second screw thread is an external screw thread.
  • the outer plug comprises a thrust face.
  • the contact ring comprises a ring contact face.
  • the contact section comprises an abutment face oriented towards the thrust face and a plug contact face ori ⁇ ented towards the ring contact face.
  • the abutment face of the contact section of the inner plug comprises the shape of a circular ring. The abutment face is thus rotationally symmetric, allowing to arrange the inner plug at arbitrary angular orientations.
  • the abutment face comprises the shape of a slotted circular ring.
  • the slots decrease the total area of the abutment face, thus increasing a pressure force exerted on the remaining parts of the abutment face by the thrust face of the outer plug. This also increases a contact force exerted between the plug contact face of the contact section of the inner plug and the ring contact face of the contact ring of the cable terminal .
  • the slots arranged in the abutment face of the contact section of the inner plug increase the flexibility of the contact section of the inner plug, thus allowing the plug contact face of the contact section of the inner plug to closely adapt to the shape of the ring contact face of the contact ring of the cable terminal, for example to surface roughnesses.
  • this may equalize manufacturing tolerances .
  • the plug contact face and/or the ring contact face comprise an embossment.
  • the embossment may for example comprise a number of ridges. The embossment reduces a contact area between the plug contact face of the contact section of the inner plug and the ring contact face of the contact ring of the cable terminal and thus allows for increased contact pressure between the plug contact face and the ring contact face.
  • the plug contact face and/or the ring contact face comprise an impression cor ⁇ responding to the embossment.
  • the plug contact face may comprise an impression and the ring contact face may comprise a corresponding embossment.
  • the plug contact face may comprise an embossment and the ring contact face may comprise a corresponding impression.
  • the impressions and embossments pro ⁇ vide areas of the plug contact face and the ring contact face that are inclined with respect to a normal direction of the plug contact face and the ring contact face. This increases the size of the contact area between the plug contact face and the ring contact face and increases a contact pressure resulting from a given force exerted on the contact section of the inner plug by the outer plug.
  • an electrically conductive interim piece is arranged between the ring contact face and the plug contact face.
  • the interim piece may for ex ⁇ ample comprise a metal or be provided with an electrically conductive coating.
  • the interim piece may be designed to in ⁇ crease a contact area between the ring contact face and the plug contact face or to increase a contact pressure between the ring contact face and the plug contact face.
  • the interim piece may be rigid and stiff or may be flexible like films or elastic like wavy washers.
  • the interim piece may also serve to level imperfections and irregularities of the plug contact face and/or the ring contact face.
  • the interim piece may com ⁇ prise a metal or a metal alloy, for example copper beryllium, or another conductive material and/or may comprise a conduc- tive coating, for example a silver plating.
  • the thrust face and the abutment face are at least partially inclined with respect to a direction perpendicular to the longitudinal di- rection.
  • the thrust face and the abutment face may be in ⁇ clined about a positive or a negative angle.
  • the inclination of the thrust face and the abutment face advantageously in ⁇ creases the areas of the thrust face and the abutment face and increases a contact pressure between the thrust face and the abutment face at a given force exerted on the contact section of the inner plug by the outer plug.
  • the plug contact face and the ring contact face are at least partially in- clined with respect to a direction perpendicular to the longitudinal direction.
  • the plug contact face and the ring con ⁇ tact face may be inclined about a positive or a negative an ⁇ gle.
  • the inclination of the plug contact face and the ring contact face advantageously increases the size of the plug contact face and the ring contact face and may increase a contact pressure between the plug contact face and the ring contact face that results from a given force exerted on the contact section of the inner plug by the outer plug.

This may enable the contact section 440 of the inner plug 400 to adapt to slight unevennesses of the thrust face 540 of the outer plug 500 and the ring con ⁇ tact face 250 of the cable terminal 200 and may ensure an im ⁇ proved contact and an increased contact pressure in case of such unevennesses.

Smaller areas of the plug contact face 450 and the abutment face 460 of the con- tact section 440 of the inner plug 400 may result in higher pressures at the interface between the thrust face 540 of the outer plug 500 and the abutment face 460 of the contact sec ⁇ tion 440 of the inner plug 400 and at the interface between the plug contact face 450 of the contact section 440 of the inner plug 400 and the ring contact face 250 of the contact ring 210 of the cable terminal 200.

  • the reduction of the nom ⁇ inal contact area between the plug contact face 450 and the ring contact face 250 may increase a contact pressure between the parts of the plug contact face 450 and the ring contact face 250 that are in contact. This may ensure and improve an electric connection between the contact section 440 of the inner plug 400 and the contact ring 210 of the cable terminal 200.
