Definitions

  • the invention relates to an electrical connector for communication and data technology according to the preamble of claim 1.
  • a connector of the generic type is previously known from EP 0.445.376 A1.
  • This consists of a housing with a receiving chamber for a plug, a first set of contacts using insulation displacement technology and a second set of contacts (RJ contacts) connected to the first set of elongated contact strips, which are introduced into grooves in the housing upper part are parallel and close together are guided to each other up to the receiving chamber in which the plug (RJ plug) can be inserted.
  • the shielding of HF cables is carried out by contacting the cable shield of the HF cable with another additional contact. This additional contact prevents a compact design of the connector.
  • the invention is therefore based on the object of improving an electrical connector of the generic type in such a way that shielding of RF cables integrated in the connector is possible.
  • the shielding cable of an RF cable can be securely connected to the shield contact with the aid of a crimp connection and can be connected to earth potential or continued via the earth wire contact.
  • the connector 25 known from EP 0.445.376 A1 according to FIG. 1 has a housing made of an upper part 10 and a lower part 11 made of injection molding.
  • the upper part 10 has opposite, essentially rectangular side walls 14, 15, which are each provided with a through opening 16 for engaging wedge-shaped projections 43 of the lower part 11.
  • the front end wall 22 of the top 10 is provided with a series of parallel grooves 24 communicating with similar grooves 26 formed in the bottom wall of the top 10.
  • Each of the grooves 26 extends to near the lower part of a slot 20 defined by the columnar lugs 18.
  • the front end wall 22 also has opposite, molded and angled, flange-like side parts 28, 29, each form a channel 30.
  • the upper part 10 is provided with integrated hooks 33, which form clamping elements for electrical conductors.
  • the lower part 11 is provided with a substantially flat end section 40 with opposite side walls 42, the outer surfaces of which are provided with the wedge-shaped projections 43. Inward flanges 44 are provided on the inside of each side wall 42.
  • the front end portion 45 of the lower part 11 has an integrally formed part which defines a cavity 50 for receiving a plug, such as a plug attached to the end of a line coming from a telephone device or a computer terminal.
  • a plug such as a plug attached to the end of a line coming from a telephone device or a computer terminal.
  • upright columns 56 arranged in opposite directions are formed approximately in the middle of the lower part 11.
  • the lower part 11 comprises on the front a flat wall 58 which extends upright at a height of approximately the height of the columns 56.
  • the other end of wall 58 terminates at protruding portions 60 from each of side walls 42.
  • Base 11 may receive a closure cap 70 which is disposed between opposite side walls 42 and held in place by flanges 44.
  • the closure cover 70 can be moved between a position in which it closes the access to the cavity 50 and a position in which the cavity 50 is open.
  • a spring 72 is attached to the cap 70 to bias it toward the closed position.
  • the set of eight electrical connecting elements 80 extends into the slots 20 formed in the upper part 10 by the columnar extensions 18.
  • Each of these connecting elements 80 is provided with an insulation displacement contact element 81, which is fork-shaped and defines a relatively narrow contact slot 82, which opens into a wide insertion section 83.
  • the arrangement is designed such that when an electrically insulated conductor is inserted into the insertion section 83 and when the latter is pushed into the narrow contact slot 82, the insulation of the conductor is cut automatically, so that contact between the central core of the conductor and the material of the connecting element 80 will be produced.
  • the insulation displacement contact elements 81 are arranged substantially flat and at an angle of approximately 45 ° to a line through the columnar lugs 18, i.e. at 45 ° to the plane of each slot 20.
  • Each connecting element 80 is further provided with a foot section 85 which is formed in one piece with the insulation displacement contact elements 81.
  • a second set of connecting elements 90 has a row of eight contact tongues 92, which are each welded to a foot section 85.
  • An elongated contact strip 93 extends from each contact tongue 92.
  • the contact strips 93 are designed such that they run parallel to one another.
  • the contact strips 93 open as RJ contacts 1 to 8 in the cavity 50 for the RJ plugs of end devices.
  • FIG. 2 shows the assembled connector 25 described in detail in FIG. 1 with a shield contact 1 and an earth wire contact 5.
  • the RF cable 94 to be connected is shown with a crimp ring 23.
  • the shield contact 1 is formed in one piece from a shaped sheet 34. On two opposite sides, the shaped plate 34 is angled downward at an angle of 90 ° in two rectangular bends 35. These first extend over the full width of the shaped plate 34 and then taper to form stirrups 3 with spring tabs 37, which are formed at right angles and are bent outward at their ends at an obtuse angle. In the middle of the shaped plate 34 there is a U-shaped free cut 36 which forms an upwardly bendable lip 2 of the shield contact 1. The bent lip 2 projects beyond the bend 35 forming the bracket 3.
  • the lip 2 is provided in the central region with rectangular cutouts 38, so that a web 39, which is only slightly wider than the lip 2, projects beyond the lateral bend 35 in the middle of the shaped plate 34.
  • a further bend 27 is formed, which forms the rear wall 4 of the shield contact 1.
  • the ErdbeivierdrahtWallet 5 is integrally formed from a shaped sheet which is formed on the long sides of narrow webs 9. At the front is the shaped sheet angled upwards by 90 ° and forms the end face 13. On the outer sides of the webs 9 there are barbs 6 which are bent upwards at right angles in the area near the end face 13 turned above. In addition, 9 notches 12 are formed on the outside of the webs. At the end remote from the end face 13, the webs 9 are bent downwards at right angles and then run in a plane parallel to the original plane of the webs 9. On the outside of the front web 9 in FIG. 2, a wall 17 projects upward, the rear web 9 being partially cut free in the region of the wall 17.
  • the left side of the rear web 9 is widened somewhat towards the outside.
  • a sheet 31 is angled upwards at right angles, which has inward angled portions 32 on both sides.
  • a tongue 21 is cut free from the center, which is bent inwards at two angles.
  • the sheet metal 31 is cut free from the inward-facing side bends 32.
  • the part of the sheet 31 cut free in this way acts like a resilient sheet 7.
  • the inward-facing side bends 32 are cut away, hooks 19 rounded inward being formed.
  • the lip 2 of the shield contact 1 cut free from the shaped sheet 34 is bent upwards.
  • the RF cable 94 to be shielded is stripped and the exposed cable shield 95 is bent back onto the remaining insulation.
  • the cable shield 95 is connected to the lip 2 of the shield contact 1 by means of a crimp connection.
  • the crimp connection is preferably carried out as shown in FIG. 2 by means of a crimp ring 23. However, the crimp connection can also be carried out by means of a cable tie with a metal clip.
  • the eight cables 97 of the HF cable 94 are contacted by means of the insulation displacement contact elements 81.
  • the rear wall 4 of the shield contact 1 is inserted into the remaining slot between the grooves 24 of the upper part 10 and the lower part 11.
  • the brackets 3 of the shield contact 1 are thereby on the wall 59 of the lower part 11.
  • the brackets 3 of the shield contact 1 are bent away from the wall 59 of the lower part 11 at an obtuse angle in the lower part. This serves to simplify the passage of the barbs 6 of the earth wire contact 5 through the passage 91 of the lower part 11.
  • the barb 6 is then conductively connected to the bracket 3 of the shield contact 1 on the wall 59 of the lower part 11. After the barb 6 is inserted through the feedthrough 91, its bent part rests on the top of the part 60 and thus fastens the ErdbeilaufdrahtWallet 5 on the lower part 11 of the connector 25.
  • the flanges 8 of the Erdbeilaufdrahtgiftes 5 lie on the inner walls of the cavity 50 of the Connector 25 and serve for further attachment.
  • the webs 9 the Erdbeilaufdrahtgiftes 5 lie flat on the underside of the lower part 11 of the connector 25.
  • the notches 12 of the Erdbeilaufdrahtgiftes 5 are guided past the flanges 44 of the lower part 11.
  • the end face 13 is passed between the two parts 60 of the lower part 11 and lies in the lower part against the wall 58 of the lower part 11.
  • the fastening wall 17 of the earth wire contact 5 lies against the rear wall of the upper part 10, which is not visible in the perspective shown.
  • the actual Erdbeilaufdrahttitle 5 is formed by the resilient sheet 7 and the hook 19. If an earth lead wire 96 is present, it is connected to the earth lead wire contact 5. For this purpose, the resilient sheet 7 is pressed between the hooks 19 in the direction of the barbs 6. The Erdbeilaufdraht 96 is then resiliently clamped between the resilient sheet 7 and the hook 19.
  • the structure of the actual ErdbeilaufdrahtMessagees 5, formed from the hook 19 and the resilient sheet 7, lies on the rear wall of the last columnar extension 18 of the upper part 10 of the connector 25.
  • the closure cover 70 described in FIG. 1 can also be pushed onto the plug connector 25 when an earth wire contact 5 is used.
