Definitions

  • the present invention relates to a connector for data transmission cable having a plurality of electrical conductors, which are twisted in pairs, for example.
  • the invention relates to a connector according to an international standard, for example the standard IEC 60603-7 (called RJ45 for short) or IEC 61076-2-xx (circular connector for the low-voltage range, representative of this: M12).
  • Data transmission systems having a plurality of electrical conductors, in particular of the twisted-pair type, are still increasing in importance.
  • the structured building cabling has great success. This is based among other things on standardized connectors.

Methods are known that, for example, a pair of contact elements crossed in the half of the parallel extension direction or that are formed on individual contact elements compensation surfaces, which produce an additional, targeted crosstalk between suitable contacts.
  • insulation displacement technology is particularly well suited as a connection technique.
  • insulation displacement contacts IDC

  • a Bescharis republic is used, in which the conductors are inserted in advance and which is moved for contacting in the axial direction relative to the connector housing.
  • Such a connector usually has a central hole through which the cable is made. After that, the The conductor is held at an angle to the cable direction in the wiring piece and presented for contacting with the IDCs (see eg EP 0 899 827 . DE 102 58 725 . US 6,752,647 ).
  • these termination techniques have the potential to meet the requirements in terms of their size, their handling and stability do not allow them to cover the entire cable cross-sectional area required in the new fields of application.
  • the object of the invention is to provide a plug connection part (ie in general a plug or a socket) for an electrical data transmission cable which, for example, is based on insulation displacement technology and overcomes disadvantages of plug connection parts according to the prior art.

  • the plug connection part or connection system part has a coupling element with a first coupling surface of an electrically conductive material, which is guided parallel to a first conductor or contact element section, and with a second coupling surface parallel to a second conductor or Contact element section is guided, wherein a third conductor or contact element portion between the first and second conductor or contact element portion is located, and wherein at least one connecting part connects the first and second coupling surface with each other.
  • the coupling element selectively couples sections of parallel guided, selected conductors of a data transmission cable capacitive.
  • the new method described herein assumes that the coupling between non-adjacent conductors or contact elements is with an additional component which is separated from the pair contacts by a dielectric (e.g., air or foil).
  • This additional coupling element includes two surfaces creating the desired coupling (here, for example, to 1b and 2b) and a connecting part connecting these two coupling surfaces.
  • the connecting part has the smallest possible coupling to the intermediate contact element or conductor. This can be realized in that the connecting part has at least one recess or that the distance to the intermediate contact element or conductor is greater than in the coupling surfaces.
  • the coupling element may e.g. be hat-shaped or the intermediate contact element or the intermediate conductor may be lowered.
  • a coupling element of this type is used as mentioned in connector parts of the type described above. It is also useful with differently designed connector parts or in connection systems such as contact elements of connection and distribution strips.

  • Each insulation displacement terminal or each piercing contact can be electrically connected to one of the contacts.
  • the invention is characterized essentially by the fact that the terminal housing is formed so that the terminal contact elements are not inserted from the outside into the terminal housing, whereas generally in the wiring, the conductors are supplied to the housing from the outside.
  • connection housing may, for example, have a transverse web which runs in the radial direction outside the connection contact elements and longitudinal webs, between which the isolated conductors are introduced upon contacting, mechanically stabilized.
  • the chambers for the example. Used insulation displacement terminals can be formed according to the needs.

  • an electrically insulating release film may be arranged, which may extend along a (middle) level and the terminal contact elements of the two parts of the terminal block from each other electrically insulated.

These opening directions are not axial (with respect to the plug axis), i. they form an angle to the axis of the connector part (or of the cable). Preferably, the opening directions are perpendicular to a connector axis. It is then possible on both sides, radial wiring. An analogous structure with a radial circuit is also possible in the case of piercing contacts, i. the piercing tips protrude in different - preferably opposite - non-axial directions. In the case of the above-mentioned NEXT compensation, it is preferable to couple terminal contact elements with different - ie, for example, opposite - insulation displacement opening directions.

  • the embodiment according to FIG. 16 differs from the one according to FIG. 15 in that the wiring cover 516 is displaceable between a first position and a second position not translationally, but by a pivoting movement. For this purpose, they have in a corresponding recess 11.8 of the terminal block 11 latchable pivot pin 516.4.
  • a latching projection 516.5 is designed to lock the pivot cover in a first or second position by latching into a first 11.3 or second latching hole 11.4. Otherwise, the function of the pivotable wiring cover 516 is analogous to that of the wiring cover 416 according to FIG.
  • the pivotable wiring cover 516 has the advantage that the distance between the outer jacket of the connection cable and the wiring cover can be kept smaller. This is because, in the first position of the wiring cover, the radial position of the through holes 516.1 is more favorable (ie closer to the plug axis) than in the embodiment according to FIG. 15 ,
  • Both in the embodiment according to FIG. 15 as well as in those according to FIG. 16 can connect instead of the drawn and described embodiment of the - then possibly relatively short - through holes open chambers in the manner of insertion slots. These lead individual (not stripped) ladder sideways.
  • the plug-side existing guide holes may also be omitted.
  • the open chambers (insertion slots), for example, extend to the plug-side end of the wiring cover. It can then still Holding means are present, which prevent retraction of the once introduced conductors or counteract; this holding function can be perceived in the case of existing guide holes of these.
  • Both the guide holes and otherwise the holding means may have for this holding function elements which protrude from the outside into the hole or the chamber and are swung out to the plug side during insertion of the conductors. When attempting to pull the ladder out, they tilt and act like a barb.
  • FIGS. 17 and 18 is still a variant of a connector part 1, namely a connector drawn, in which no individual conductor must be threaded through feedthrough holes.
  • FIG. 17 shows the connector part, wherein the wiring cover 616 is drawn away from the remaining connector part.
  • the orientation of the wiring cover corresponds to that according to the first, open position.
  • FIG. 18 For example, the wiring cover 616 is drawn in a position between its first and second closed positions.
  • the wiring cover 616 is in two parts, with a hinge-like connection 616.1 1 between the second parts. Between the two wiring cover parts, a cable through hole 616.2 for the whole cable is formed.
  • the two parts each have a plurality of chambers 616.3 open on one side (corresponding to the plug side when the wiring cover is in its first position) in the manner of insertion slots.
  • the insertion slots may have 616.4 and / or retaining lugs 616.5 in known manner, holding and / or clamping means through which once introduced into the chamber ladder can be held in position.
  • detent means 616.6 may be present by which the wiring cover can be locked at least in its second position relative to the terminal block 11.
  • the shielded cable is stripped on the connection side, for example, and the shield braid is covered over the outer jacket of the cable. Then the stripped cable is passed through the cable passage opening 616.2, wherein the connection cover, for example, separated from the rest of the connector part and in a semi-open position (corresponding to the in Fig. 18 drawn) is held. At the periphery of the cable feed-through opening 616.2 there may still be clamping ribs 616.7, by means of which the relative position of the cable wiring cover for the wiring process is easily fixed after being inserted into the first, in Fig. 17 drawn position was brought. Then the individual conductors (not stripped) are inserted into the open chambers provided for this purpose.
  • the holding and / or clamping means 616.4 and / or the retaining lugs 616.5 By light pressure, they are clamped by the holding and / or clamping means 616.4 and / or the retaining lugs 616.5 and held in position. They should protrude at the outer (ie in the figure upper or lower) side of the pivot cover. Then protruding ends of the conductors are cut off, and the wiring cover is clipped onto the remaining connector part and snapped by a pivotal movement of its two parts on the terminal block 11. In this case, as in the embodiments described above, the conductors are contacted by the insulation displacement terminals.
  • additional strain relief can be provided here as well. These may, for example, be present on the housing and attack on the cable as a whole. Alternatively or additionally, for example, by an axial positive connection between the wiring cover and terminal block in the closed state, an additional strain relief may be present. Also zugentlastend the possibly existing holding and / or clamping means 616.4 act.
  • FIGS. 15 to 18 can - as well as all other embodiments have a terminal block and a contact block, such as which is described and drawn in the above embodiments. However, this is also in these embodiments, no need, ie male contact elements and terminal contact elements may be carried by the same housing or even be integral with each other. Also, the bipartite of the terminal housing is as in the preceding embodiments, a possible, but not necessary embodiment of the connector part according to the invention.
  • the contact block may be designed according to a different plug standard than the RJ45 standard, for example according to the M12 standard which is widespread in industry.
  • the bipartite terminal block contact block is not necessary; the terminal housing may instead also form the plug housing.
  • separate contact elements are not necessary, the (plug) contacts may be formed on the terminal contact elements.
  • the drawn formations of the terminal contact elements and contact elements are to be understood merely as examples.
