Definitions

  • the present invention relates to a plug-guiding attachment for rotatably orientating a plug element with respect to a receptacle of a mating plug element, the plug-guiding attachment adapted to be positioned before the receptacle in a plug-in direction of the plug element.
  • the present invention relates to an electrical plug-in connector comprising a receptacle for an electric plug element.
  • the present invention relates to an electrical plug-in connector comprising a plug-guiding attachment positioned before a receptacle for a plug element in a plug-direction of the plug element.
  • Plug-guiding attachments electrical plug-in connectors comprising receptacles for such attachments or comprising these attachments are known in the form of simple collars surrounding a receptacle (e.g. a mini-DIN plug receptacle) extending therefrom against the plug-in direction. These plug-guiding attachments laterally support a plug during its insertion into the receptacle.
  • an object underlying the invention is to facilitate correctly orientating a plug element with respect to the receptacle.
  • the plug-guiding attachment comprises at least one fastening organ defining a predetermined orientation of the plug-guiding attachment with respect to the receptacle, and a passage having an inner contour defining a predetermined rotational orientation of the plug element with respect to the plug-guiding attachment about a rotation axis of the plug element, the rotation axis extending parallel to the plug-in direction.
  • the object is achieved according to the present invention in that the receptacle is provided with a plug-guiding attachment socket complementing a plug-guiding attachment according to the present invention.
  • the object is achieved in that the plug-guiding attachment provides a passage having an inner contour defining a predetermined rotational orientation of the plug element with respect to the plug-guiding attachment about a rotation axis of the plug element, the rotation axis extending parallel to the plug-in direction.
  • plug elements having an outer contour which is not adapted to match the plug-guiding attachment may be compatible to the receptacle in that they may simply reach through the plug-guiding attachment without any rotational orientating engagement therewith.
  • the inner contour can be designed to engage an electrically insulating outer housing body of the plug element. Hence, mechanical stresses on the conductive parts of the plug face may be reduced.
  • an inner contour provides a pattern for the orientation of the plug element by being adapted to engage a handling section of the plug element. This facilitates coarsely orientating the plug element with respect to the receptacle before insertion because the handling section may comprise an indication for the correct orientation which may also be implemented on the plug-guiding attachment.
  • the pattern assures a precise alignment of the plug element in order to be precisely inserted into the receptacle. Further, the pattern may provide a coding of the plug element, i.e. that only a certain type of plug element and a respective plug-guiding attachment match.
  • Pre-orientating the plug element with respect to the receptacle may be further facilitated according to another possible embodiment of a plug-guiding attachment in that a depth of the passage measured parallel to the plug-in direction exceeds a length of contact pins and/or a protective collar arranged around these contact pins.
  • mini-DIN plugs have such a metal collar arranged around their contact pins.
  • the fastening organ is arranged at an outer circumference of the plug-guiding attachment.
  • the fastening organ may provide a coding of the plug-guiding attachment with respect to a plug-guiding attachment socket.
  • the arrangement of the fastening organ at the outer circumference may render the plug-guiding attachment asymmetric in a way that an unequivocal correct orientation of the plug-guiding attachment with respect to the socket is defined.
  • a plug-guiding attachment according to the present invention may easily be fixed to a plug-in connector when the fastening organ is provided with a latching element. This possible embodiment enables to easily fix the plug-guiding attachment without assistive equipment or auxiliary means.
  • the fastening organ may comprise a latching pin.
  • This latching pin may protrude from the outer circumference of the plug-guiding attachment.
  • the latching pin may be complemented by a socket for the fastening organ.
  • a correct rotational orientation of the plug element with respect to the plug-guiding attachment may, according to another possible embodiment of a plug-guiding attachment, be easily provided in that the inner contour in a projection along the plug-in direction has at least one rounded section and at least one angular section. This renders the inner contour asymmetric and provides a distinct pattern and furthermore a coding of the plug element with respect to the plug-guiding attachment.
  • a plug-guiding attachment according to the present invention may be especially adapted to mini-DIN-sockets, when according to another possible embodiment it is provided that the plug-guiding attachment has the shape of an annular collar designed to fit around a mini-DIN-socket. Thereby, the plug-guiding attachment may extend the receptacle provided by the mini-DIN-socket.
  • a plug-guiding attachment according to the present invention may be easily manufactured if according to another further embodiment it is provided that it is formed of plastic in one piece.
  • An electrical plug-in connector according to the present invention comprising a receptacle for an electric plug element, may be further improved in that a fastening organ socket is formed at an outer circumference of the plug-guiding attachment socket. Thereby, a correct orientation of the plug-attachment with respect to the plug-guiding attachment socket may be unequivocally defined.
  • An electrical plug-in connector according to the present invention may be especially suited for mini-DIN-sockets, when it is provided that the plug-guiding attachment socket surrounds a mini-DIN-socket.
  • an electrical plug-in connector 1 comprises a plug element 2, a mating plug element 3 and a plug-guiding attachment 4.
  • the plug element 2 comprises a plug section 5 which protrudes from an outer housing body 6 in a plug-in direction P of the connector 1 and also of the plug element 2.
  • the plug-section 5 may comprise a conductive collar in the form of a circular shielding metal skirt surrounding several contact pins as known for example from mini-DIN connectors having a 9.5 mm diameter.
  • These connectors come in seven patterns and comprise a number of pins from three to nine. The seven patterns are well known in the state of the art as they are official standards, each having their distinct plug faces defined by their collar, notches and metallic additions.
  • the housing body 6 has an essentially circular cross-section in a middle part but is provided with a handle 7 in the vicinity of the plug-section, such that there the cross-section of the plug element has a circular and a cornered portion.
  • the handle 7 is flattened at the top.
  • the housing body 6 is provided with a strain relief which is adapted to enclose a cable (not shown) attached to the plug element 2.
  • the flat zone of the handle 7 may provide a pattern for sensing a correct orientation of the plug element 2 with respect to the plug-guiding attachment 4 before insertion. Furthermore, during insertion the flattened zone may provide a guidance assuring that the correct rotational orientation is maintained.
  • a rotation axis R of the plug element 2 runs through the center of the circular portion of the housing body and through the center of the plug-section 5.
  • the mating plug element 3 is provided with a receptacle 8 complementing the plug-section 5 of the plug element 2.
  • the receptacle 8 has the form of a mini-DIN-socket having a plug face 9 with several contact pin sockets 10 for accommodating the contact pins (not yet shown) of the plug element 2. Further, the plug face 9 is provided with a notch 11 for accommodating a key provided in the plug-section 5.
  • the mating plug element is provided with a wall mounting plate 17 for mounting the mating plug element 3 to a wall and a face plate 18 for covering the mating plug element 3.
  • the face plate 18 is provided with an aperture 18a through which the plug element 2 may be inserted into the receptacle 8.
  • the plug-guiding attachment 4 has an essentially circular outer contour 19 which could have any other suitable shape instead of being circular.
  • the plug-guiding attachment 4 is provided with a fastening organ 20 which at least sectionwise comprises or has the form of a latching pin 21.
  • the fastening organ 20 protrudes from the outer contour 19 perpendicularly to the plug-in direction P and extends from the plug-in guiding attachment 4 in the plug-in direction P.
  • a passage 23 of the plug-guiding attachment 4 provides a lead-through for the plug element 2.
  • the passage 23 has an inner contour 24.
  • the inner contour 24 has a rounded section 25 and an angular, i.e. cornered section 26 which together are designed to complement the outer contour of the plug element in the area of the handle 7.
  • a rim 27 is formed, which faces towards the plug-in direction P and has an indication 28 indicating a correct rotational orientation of the plug element 2 with respect to the mating plug element 3.
  • Fig. 2 shows the plug-in connector 1 in an end-position E, where the mating plug element 3 is fully assembled, the plug-guiding attachment 4 sits within the plug-guiding attachment socket 14.
  • the plug element 2 is plugged through the passage 23 into the receptacle 8, such that the collar of the plug-section 5 sits within the collar socket 12 and the contact pins sit within the contact pin sockets 10.
  • Fig. 3 shows the plug-in connector 1 in a near-end position N on the cross-section line X-X depicted in Fig. 2 .
  • the plug element 2 is aligned with the plug-guiding attachment 4 such that a front edge 29 of the handle 7 is on the same level with the rim 27 in the plug-in direction P. This can especially be seen in detail A.
  • the collar 30 of the plug-section 5 is partly inserted into the collar socket 12 and contact pins 31 of the plug element 2 are not yet inserted into the contact pin sockets 10, i.e. their tips are positioned in the plug-in direction P just before the contact pin sockets 10.
  • the arrangement of the contact pins 31 before entering the contact sockets 10 may best be seen in detail B.
  • the plug element 2 may still be turned around a rotational axis running parallel to the plug-in direction P.
  • the front edge 29 at the outer housing 6 of the plug element 2 may be used to rotatably orientate the plug element 2 with respect to the plug-guiding attachment 4 and hence with respect to the receptacle 8.
  • the plug-guiding attachment 4 provides that the plug-in connector 1 is not only guided as well as coded by the receptacle 8 and the plug-section 5, as usual, but further guided and coded by the inner contour 24 of the passage 23 and the outer contour of the housing body 6.
  • the outer body 6, in particular the edge 29, engages with the passage 23, before the contact pins 31 and/or the collar 30 reaches the plug face 9. This is achieved in that a depth d of the passage 23, i.e. a length of the passage 23 measured in the plug-in direction P, exceeds a length of the contact pins 31 and/or the collar 30 protruding from the front edge 29.
  • the plug element 2 and the mating plug element 3 may be designed as a plug socket as necessary.
  • the plug-guiding attachment 4 may be integrally formed, i.e. manufactured as one piece with the mating plug element 3, e.g. as a part of the face plate 18 or as a form of extension of the receptacle 8.
  • the plug face 9 may be provided with as many contact pin sockets 10, notches 11 and collar sockets 12 in whatsoever form suitable for the desired application.
  • the plug-guiding attachment socket 14 may be matched to the outer contour 19 of the plug-guiding attachment 4 in any way suitable for providing a correct orientation of the plug-guiding attachment 4 with respect to the receptacle 8. It is advantageous if the outer contour 19 is rendered asymmetric by a one-sided fastening organ 20 which thereby defines an unequivocal right way, i.e. correct orientation of the plug-guiding attachment 4 with respect to the socket 8.
  • the fastening socket 15 and the fastening organ 20 may have any complementary form which is advantageous for affixing the plug-guiding attachment 4.
  • the fastening organ 20 may be designed or provided with a latching pin 21 and a latching element 22 as desired for locking the plug-guiding attachment 4 in a mounted position as shown in Fig. 3 .
