Definitions

  • the invention relates to a connection device for communication and data technology, from a terminal block with a plurality of contact elements inserted one behind the other in the longitudinal direction thereof for the connection of cables provided with a screen braid, supplied transversely to the longitudinal direction of the terminal block, and with a shielding device for the cables.
  • a known connection device for communication and data technology comprises a terminal block plugged onto a base frame made of profiled rods with a metal plate connecting them as a shielding device for the cables fed transversely to the terminal block.
  • This shielding device for the cables fed to the terminal strip does not meet important requirements if the use of the connecting device is intended in high-speed networks of communication and data technology.
  • the communication transmission over transmission paths with 100 Mbit / s or the use of such connection devices in the frequency range from 20 to 100 MHz provides among other things. the highest demands on crosstalk and crosstalk attenuation, which are not met by the known shielding device for the cables. Especially at higher frequencies, the quality of the shielding device is decisive for the quality of the data transmission.
  • the invention is therefore based on the object of improving the connection device of the generic type with regard to the quality of the shielding device.
  • the invention provides that a shielding device is provided for each two, with their cable wires connected to the terminal block opposite, provided with a shielding braid, which is arranged transversely to the longitudinal direction and on both sides of the terminal block parallel to the cable wires. This will make the Shielding of the opposite cables connected with their cable cores to the connection strip is passed on separately from the other cables connected to the connection strip, so that the quality of the shield transmission is significantly increased.
  • the connecting device according to the invention the potential of the shielding of each individual cable is thus passed on to the potential of the other cable, the individual cable cores of which are connected to one another. This is particularly important for improving the quality of the screen forwarding at higher frequencies in the data transmission.
  • the shielding device for a pair of cables connected on the opposite side of the connecting strip is formed from a cable holder receiving the latter and its shield braid and two shielding plates engaging in the latter, encompassing the connecting strip on both sides, which are received by a strip holder surrounding the connecting strip.
  • the connection device 1 for communication and data technology consists of a terminal block 2 with four shielding devices 3 each consisting of two shield plates 4 and a cable holder 5 for two supplied cables 6, 7 and a strip holder 8 made of a U-shaped wire guide body 9 with five web plates 10 and a base body 11 with two end plates 12.
  • a front plate 13 is provided, through which plugs 14 with tongues 15 can be inserted into the terminal block 2.
  • the terminal block 2 comprises a plastic body 16 with longitudinally inserted contact elements, not shown, which are regularly formed from insulation displacement contact elements and have a center tap, not shown, for inserting the tongues 15 of a connector 14.
  • the plastic body 16 has at its two longitudinally spaced ends clamping pieces 17 for clamping the terminal block 2 on the profile rods of a base frame, not shown.
  • the base body 11 of the strip holder 8 comprises four adjacent transverse guides 18 for receiving a cable holder 5 each, as well as the two end plates 12, which each have a pair of spaced-apart clamping pieces 19 at their ends projecting over the basic body 11, which, when the connecting device is assembled, with the clamping pieces 17 of the terminal block 2 are aligned and can be snapped together with them onto the profile rods of the base frame, not shown.
  • the V-shaped wire guide body 9 engages with its U-shaped web plates 10 between the two end plates 12 of the base body 11.
  • 10 guide channels for the are on both sides of the V-shaped wire guide body 9 and between two adjacent web plates Cable 6, 7 and their cable cores 20 are formed, which are connected to the insulation displacement contact elements, not shown, of the terminal strip 2, as shown in FIGS. 1 and 2.
  • two adjacent web plates 10 each serve to accommodate two opposite shield plates 4, as shown in FIG. 2.
  • Each cable holder 5 is provided with two conical receptacles 21 lying next to one another, in which conical sleeves 22 are inserted, which are pushed onto the cables 6, 7.
  • the braided shield of the associated cable 6, 7 is placed around the cone-like sleeve 22 and pressed into the cone-like receptacle 21 of the cable holder 5.
  • Lugs 23 formed on the cylindrical part of the outside of the sleeve 22 come into engagement with catches 24 on the cylindrical part of the receptacle 21. This results in a firm, conductive connection between the braided shield of the cable 6, 7 and the cable holder 5.
  • This consists of metal or metallized plastic in order to be able to transmit the potential of the braided screen.
  • a cable holder 5 equipped in this way with two cables 6, 7 and associated sleeves 22 is inserted into a transverse guide 18 of the base body 11 of the strip holder 8, and the cables 6, 7 are fixed to a cable clamp 25, which is part of the base body 11.
  • the cable holders 5 are provided on both ends with locking brackets 27, into which locking lugs 28 engage, which are recessed at one end of the shield plates 4.
  • the shield plates 4 encompass the terminal block 2 and the cable wires 20 connected to it with a bulging area 29 and are locked at the other end with locking shoulders 30 for locking onto locking grooves 32 formed on the end faces 31 of the U-shaped web plates 10, as shown in FIG. 2 is shown.
  • the shield plates 4 are provided at their ends provided with the locking shoulders 30 with shield taps 26 for attaching the shield taps 34 of the shielded plug 14 which can be inserted into the terminal strip 2, as shown in FIG. 2.
  • the shield taps 26 of the shield plates 4 pass through an opening 33 in the front plate 13.
