Definitions

  • the invention relates to a device for connecting a plurality of plugs to a standardized socket and a plug system and a plug-distribution module.
  • connectors For electrical signal cables in building wiring, there are worldwide used and standardized connectors, such as the widely used RJ45 connector (international standard IEC 60603-7) and the related connectors according to the standard family IEC 60603-7-x, eg the IEC 60603 standard -7-7, or according to IEC 61076-3-110 and other systems compatible with these connectors, for example.
  • These connectors have in common that they each have at least eight plug contacts. Accordingly, it is common to use a cable with four twisted wire pairs per connection point.
  • connector types derived from the above-mentioned connectors, such as RJI1 and RJ12 systems have at least four plug contacts and two twisted wire pairs. Often applications are connected to the building cabling system that does not require all or all four pairs.
  • the device according to the invention has on one side (on the socket side) a plug-in part which can be inserted into the standardized socket. On the other side (plug side) a plurality of chambers is present, in each of which a plug can be inserted. Further, the device has a plurality of adapter contacts, which can be brought into electrical contact by inserting the male part into the socket with the existing socket contacts. At least two of the adapter contacts are electrically conductively contactable behind each of the chambers by plug contacts of the inserted plugs, for example by having a section exposed behind the chamber, or by being covered within the chamber by an element which pushes away by inserting the plug. or - is pivotable.
  • the chambers are at least partially within the socket opening, that is, the inserted plug engage in the socket opening, so that at least a part of the plug is located within the socket opening. Furthermore, according to the invention, they are present in an arrangement in which at least two chambers lie one above the other with respect to the socket contacts.
  • first direction (hereinafter “first direction” or “x direction”) is defined by the arrangement of the at least four adjacent socket contacts, at least two chambers are located with respect to a deviating second, for example, perpendicular extension direction (the y-direction) side by side (they are “superimposed”) and are spaced therefrom, for example at least the height of a chamber
  • the z-direction corresponds to the definition of the plug and plug axis
  • a partition between these at least two chambers extends preferably along the first direction, ie parallel to the x-axis and, for example, parallel to the xz-plane.
  • the electrical connection between the socket contacts and the plug contacts made by the device is, as mentioned above, an electrical contact, ie a direct connection which is not active or passive (with the exception of the ohmic resistance corresponding to the residual resistance of the - A -

  • the device according to the invention has a switch actuation projection, which actuates a switch in plug sockets of the standards IEC 60603-7-7 and IEC 61076-3-110 upon complete insertion of the device into the socket, which switches certain socket contacts in parallel.
  • the inventive device can also be configured for other standardized sockets, for example. For the four-pin sockets of the types RJIl- and RJ 12 and others.
  • the invention uses the knowledge that within a RJ45 socket or other standardized socket for a four- or eight-pin rectangular connector, generally with the same outer dimensions as the RJ45 socket, a plurality of chambers may be present, in each of which a plug insertable is, and that in spite of the linear arrangement of the RJ45 contacts in the socket, an arrangement of the chambers makes sense, in which these are also superimposed.
  • a device is provided which, despite the very limited space available, allows the contacts to be routed at different levels within the RJ45 (or comparable) socket.
  • the invention thus goes the way away from the linear, the RJ45 and comparable sockets own approach with contacts / plugs side by side - such an approach also corresponds to the arrangement of EP 1 128 494 - towards a two-dimensional arrangement of contacts within the example. Only 12x7 mm large socket (dimensions inside the socket, ie the socket opening). By doing so, the problem of crossing pairs 4/5 and 3/6 can be solved with RJ45 sockets, by guiding one of these contact pairs' up ', the other, down'. According to the invention, therefore, the chambers are designed and dimensioned such that at least part of the plug inserted into the chambers projects into the socket opening. This is advantageous, because this allows the device to be designed so that it does not protrude or only slightly out of the socket opening. Accordingly, it is less exposed to mechanical influences and damage, and its space requirement is small.

  • the principle of separated by partitions, located at least partially within the bushes chambers is according to a modification of the invention also applicable to at least two only side by side arranged chambers.
  • a modified device can be used for example as a splitter for the four-pin connector systems such as RJIl and RJl 2.

  • a particularly preferred use as a branch is that of an ISDN bus.
  • contact points of the adapter contacts on both sides are "male”, i.e. free of movable, resilient parts, which requires that the plugs for insertion into the chambers be “female”, i. provided with resilient contacts. It has been shown that this principle "male-male” of the device allows a particularly cost-effective and very space-saving design.
  • the interconnects forming the adapter contacts-in particular if they intersect- may still have plated-through holes between different interconnect levels, depending on the embodiment.
  • the adapter contacts are such that the pairs 3/6 on the one hand and 4/5 on the other hand are not horizontal next to each other, but on different levels (ie spaced from each other in the vertical direction) come to rest.
