Definitions

  • the present invention relates to an electromagnetic shielding arrangement according to claim 1, a shielding structure according to claim 12 and a method according to claim 13.
  • shielded cables are well known.
  • a cable comprises at least one electrical conductive conductor which is encompassed by means of an insulation, whereby on the outer side of the insulation a metallic shielding braid is arranged in order to provide an electromagnetic shielding.
  • the shielding braid is to be connected to respective shielding elements on the side of the plug or the other electrical element. Providing this connection is usually cumbersome as it requires a rather exact positioning between the end of the shielding braid and the plug.
  • a shielding arrangement which can be mounted very easily under the provision of a determined electrical contact.
  • a shielding arrangement allowing more tolerance for the connection of a shielding braid of a cable.
  • the electromagnetic shielding arrangement comprises an inner ring extending around a middle axis and having an inner surface and an outer surface, an outer ring extending around said middle axis and having an inner surface and an outer surface, which inner ring is located at least partly within said outer ring, wherein a spacing is provided between the inner ring and the outer ring, and an electrically conductive body having a bore with an inner surface, wherein said inner ring and/or said outer ring are at least partly located in said bore.
  • a shielding braid of the cable can be mechanically clamped in said spacing between the inner ring and the outer ring such that an electrical contact is provided between said outer ring and said shielding braid.
  • the arrangement further comprises an electrical contact element that is arranged between the outer ring and the electrically conductive body in order to provide an electrical contact between the outer ring and the electrically conductive body.
  • the electrical contact between the shielding braid of a cable and body which is part of a plug structure can be enhanced.
  • the electrical contact element serves to provide a determined electrical contact between the outer ring and the body.
  • body refers to structure which is part of a the shielding structure of a plug housing or which can be connected to the shielding structure of a plug housing or which is part of a shielding structure of another element or which can be connected to the shielding structure of another element.
  • clamped is to be understood in that a firm mechanical connection between the two rings and the shielding braid can be achieved.
  • the inner ring is located fully within the outer ring.
  • the inner ring and the outer ring is arranged fully in said bore.
  • the outer ring and the body are at least partly or fully made out of an electrically conductive material.
  • the inner ring can also be made of a non-conductive material, such as a plastic or fibre-reinforced plastics.
  • the electrical contact element comprises a plurality of resilient contact pieces and extends substantially fully around said middle axis.
  • the resilient contact pieces are resiliently clamped by means of their own spring force in the gap between the outer ring and the bore.
  • the electrical contact element can also be designated as contact lamella.
  • the outer ring comprises a determined contact surface with which said electrical contact element is in electrical contact and/or the bore comprises a contact surface with which said electrical contact element is in electrical contact.
  • At least one of said contact surface extends around said middle axis with a constant cylindrical diameter, wherein said contact surface has a length as seen along the middle axis which is longer than the width of the contact element as seen along the middle axis.
  • This allows positioning the contact element with a larger degree on flexibility based on the position of the cable braid as seen along the middle axis. This is a particular advantage as an accurate positioning of the elements of the shielding arrangement relatively to the end of the shielding braid is no longer necessary.
  • the position of the contact element on said contact surface can variable based on the end of the shielding braid and the location of the inner ring as well as of the outer ring.
  • the contact surface of the outer ring or the contact surface of the bore is part of a groove extending around the middle axis, wherein the contact element is arranged in said groove.
  • the groove can have different cross-sections.
  • the groove has a rectangular cross-section.
  • the groove has a dovetail cross-section.
  • the other contact surface without the groove is cylindrical with a constant diameter.
  • the groove is arranged on the outer ring and the cylindrical contact surface with the above mentioned length in relation to the width of the contact element is arranged on the body.
  • the diameter of the inner surface and of the outer surface of the inner ring ist constant over the whole length of the inner ring.
  • the outer ring and/or the inner ring comprises a crimping section which will be mechanically deformed in order to minimize the width of the spacing such that the shielding braid is mechanically clamped or crimped in said spacing.
  • the crimping section of the outer ring will be deformed such that it will be forced towards the inner ring.
  • the inner ring has a length in direction of the middle axis which is shorter or equal or longer to the length of the crimping section of the outer ring in direction of the middle axis.
  • the material thickness of the crimping section is larger than the material thickness of the inner ring. This allows a determined deformation during the crimping process.
  • the crimping section of the inner ring extends over its full length.
  • the crimping is a circular or a hexagonal crimping.
  • the contact surface of the outer ring is arranged at a distance to the crimping section as seen along the middle axis. This has the advantage that the contact surface of the outer ring will not be affected by the deformation of the crimping section and remains in its original shape after the crimping process.
  • the diameter of the contact surface of the outer ring is larger than the diameter of the crimping section.
  • the material thickness of the crimping section of the outer ring remains constant over the whole length as seen along the middle axis.
  • the front end of the inner ring is tapered towards the outer surface and/or towards the inner surface. This enhances mounting to the inner ring underneath the shielding braid, as the tapered front and allows a radial spreading of the shielding braid.
  • the body comprises on an end section an outer thread via which a threaded sleeve is connectable, which threaded sleeve preferably acts on a sealing element.
  • the body comprises on an end section a connection interface via which the body connectable to an external plug housing or via which a plug housing is integrally formed on the body.
  • the opening of the outer ring comprises a conical section.
  • the conical section allows a facile position of the outer ring.
  • the conical section is arrange underneath the contact surface with the groove.
  • a shielding structure comprises an electromagnetic shielding arrangement according to the description above and a cable having at least one electrically conductive core and an inner insulation which is encompassed by a shielding braid, wherein the inner ring is located between the inner insulation and the shielding braid, wherein the shielding braid extends into said spacing between the inner ring and the outer ring and is clamped in said spacing.
  • the invention further relates to a method according to claim 13.
  • the shielding arrangement 1 comprises an inner ring 3 extending around a middle axis M and having an inner surface 3a and outer surface 3b, an outer ring 4 extending a round said middle axis M and having an inner surface 4a and an outer surface 4b, as well as an electrically conductive body 6 having a bore 7 with an inner surface 7a.
  • the inner ring 3 and the outer ring 4 are located concentrically with each other. Additionally the inner ring 3 and the outer ring 4 are located concentrically in said bore 7.
  • the inner ring 3 is located at least partly within the outer ring 4. In the present case, the inner ring 3 is located fully in the outer ring 4. Between the inner ring 3 and the outer ring 4, there is a spacing 5 provided.
  • the spacing 5 is provided as the diameter of the inner surface 4a of the outer ring 4 is larger than the diameter of the outer surface 3b of the inner ring 3. Furthermore, with regard to the electrically conductive body 6 the inner ring 3 and the outer ring 4 are located fully in the bore 7.
  • a shielding braid 8 of a cable 2 can be mechanically clamped in said spacing 5 between the inner ring 3 and the outer ring 4. This can be seen for example in the cross sectional view of figure 3 , in which the shielding braid 8 of the cable 2 extends from the left of the drawing into the spacing 5.
  • the cable 2 comprises in the present embodiment a conductive core 22 which is surrounded by an inner insulation 23.
  • the shielding braid 8 encompasses the inner insulation 23 and serves as an electromagnetic shielding element for the cable 2.
  • the structure of the cable is shown as an example and it can have a different structure.
  • an electrical contact element 9 is arranged between the outer ring 4 and the electrically conductive body 6 between the outer ring 4 and the electrically conductive body 6 is provided.
  • the electrically conductive body 6 can be part of a shielding structure of a plug housing or it can be part of the plug housing. With this shielding arrangement it is possible to provide a facile structure in terms of its mechanical structure and in terms of proving an efficient shielding structure. Furthermore the electrical contact between the shielding braid 8 and the electrically conductive body 6 can be enhanced.
  • the electrical contact element 9 comprises a plurality of resilient contact pieces 10. With the resilient contact pieces 10 it is possible to provide the electrical contact between the outer ring 4 and the electrically conductive body 6. Thereby the resilient contact pieces 10 are clamped or braced within a gap between the bore 7 and the outer ring 4.
  • the gap is designated with the reference number 25.
  • the resilient contact pieces 10 are provided such that they contact the outer surface 4b of the outer ring 4 as well as the inner surface 7a of the bore 7. Furthermore they are resiliently located in this gap 25 such that they are always in contact with the respective surfaces 7a and 4b.
  • the electrical contact element 9 extends substantially fully around said middle axis M, such that a circular contact between the electrically conductive body 9 and the outer ring 4 can be achieved.
  • the outer ring 4 comprises a contact surface 11, which is part of the outer surface 4b.
  • the electrical contact element 9 is in an electrical contact with this contact surface 11.
  • the bore 7 comprises also a contact surface 12, which is part of the inner surface 7a of the bore 7.
  • the electrical contact element 9 is in an electrical contact with the contact surface 12.
  • the contact surface 12 arranged in the bore 6 has a cylindrical shape. Thereby it has a constant cylindrical diameter D.
  • the contact surface 12 has a length L which extends along the middle axis M. The length L is preferably longer the width W of the contact element 9 as seen along the middle axis M. This means that the contact element 9 can be positioned on the contact surface 12 at any position and it can be moved along the contact surface 12, which has the advantage that tolerances of the end of the shielding braid 8 can be compensated very efficiently.
  • the contact surface of the outer ring 4 comprises a groove 13 which extends around the middle axis M and in which the electrical contact element 9 is placed.
  • the groove has in the present embodiment the cross action of a dovetail. Thereby the electrical contact element is arranged firmly in this structure.
  • the groove can also have any other shape.
  • the outer ring 4 comprises in the present embodiment a crimping section 14.
  • the crimping section 14 is arranged at a distance with regard to the contact surface 11.
  • the crimping section 14 will be mechanically deformed. Thereby its diameter will be decreased such that the width of the spacing 5 is minimized in order to crimp the shielding braid 8 in said spacing 5.
  • the crimping can be a circular or a hexagonal crimping.
  • the inner ring 3 has a length L13 in direction of the middle axis M.
  • This length L13 is in the present case a bit longer then the length L14 of the crimping section 14 of the outer ring 4.
  • the length L13 could also be equal or shorter than the crimping section 14.
  • the contact surface 11 of the outer ring 4 is arranged at a distance in direction of the middle axis M to the crimping section 14.
  • the contact surface 11 is provided by the groove 13.
  • the contact surface 12 is oriented towards the cable 2 and the crimping section 14 is oriented towards a plug or the end of the cable.
  • the arrangement of the crimping section 14 with a distance to the contact surface 11 has the advantage that the contact surface 11 is not affected by the crimping procedure which will mechanically deform the crimping section 14. Therefore the contact surface 11 will 1not be mechanically influenced, once the crimping section 14 is deformed. Hence, the two functions "crimping" and "electrical contact” are separated from each other.
  • the diameter of the crimping section 14 is larger than the diameter of the contact surface 11.
  • the front end 15 of the inner ring 3 is tapered towards the outer surface 3a and towards the inner surface 3b. This has the advantage that the inner ring 3 can be easily moved on the inner insulation 23 of the cable 2 as well as within the shielding braid 8.
  • the body 6 comprises on an end section 16 an outer thread 17 via which a threaded sleeve 18 is connectable.
  • the threaded sleeve 18 is preferably arranged such that it acts on a sealing element 19, which can be in an elastic manner pushed towards to the outer insulation 26 of the cable 2 as well as against the body 6 in order to seal the gap between the outer insulation 26 and the bore 7 of the body so that it is not possible that moisture enters into this gap.
  • the body 6 comprises on the end section 27 a connection interface 20, via which the body is connectable to an external plug housing in an electrical conductive manner.
  • the plug housing is integrally formed on the body 6 in the region of the connection interface 20.
  • the opening of the outer ring 4 comprises also a conical section 21 which allows an easy mounting of the outer ring 4 over the inner ring 3 and the shielding braid 8.
  • a preferred embodiment of shielding structure comprises an electromagnetic shielding arrangement according to the description above and a cable 2 having at least one electrically conductive core 22 and an inner insulation 23 which is encompassed by a shielding braid 8, wherein the inner ring 3 is located between the inner insulation 23 and the shielding braid 8, wherein the shielding braid 8 extends into said spacing between the inner ring 3 and the outer ring 4 and is clamped in said spacing 5.
