It is clear that adjacent thereto, the conductor insertion opening 27 is introduced for an electrical protective earth conductor, which leads to a spring clamp connection or conductor connection 13 arranged in this region when the protective earth contact 1 is inserted into the insulating material housing 18.
  • FIG. 11 shows a perspective sectional view of an embodiment of a Abgriffsteckverbinders 17 with a three-piece protective earth contact 1. It is clear that the separate protective earth contact element 11 is slidably received in the receiving opening 30 of the insulating housing 18.
  • the protective earth contact element 11 has a widened end 31, which rests on the bearing surface of a spring element 32.
  • the spring element 32 is formed from a Federblechteil which is inserted into a turn separate sheet metal element 2.
  • a supporting plane 3 of the sheet metal element 2 is a plug-in opening 33 is provided, on which the tongue 38 of the spring element 32 is inserted, electrically conductively contacted and clamped.
  • the plug-in opening 33 may have spring tabs for this purpose. It is also conceivable that the spring element 32 in the tongue 38 has at least one exposed clamping spring.
  • the protective earth contact element 11 is pressed with its contact tip 12 in the extension direction of the finger-like webs 29 to the outside. It is clear that the protective earth contact element 11 is longer than the conductor contact elements 19, so that the contact tip 12 protrudes further outwards. In this way, the protective earth contact element 11 is leading to the other conductor contact elements 19.
  • the protective earth contact 1 is first made in this way when attaching the Abgriffsteckverbinders 17 to a power guide profile before the conductor contact elements 19 contact their respective electrical conductors.
  • the sheet metal element 2 is arranged on the underside of the insulating housing 18 below the webs 29.
  • FIGS. 3 to 5 shown embodiment of the protective earthing contact 1 in the insulating material 18 received.
  • the only difference is that the in FIG. 11 illustrated protective earth contact 3-piece and in the previous embodiments is 2-piece.
  • the spring element must therefore not as in FIG. 11 be shown as a separate part. It may also be a bent from the sheet metal element 2 spring element 9.
  • FIG. 12 shows a side sectional view of the tapping connector 17 from FIG. 11 ,
  • the protective earth contact element 11 is displaceably mounted in the receiving opening 30 of the insulating housing 18. He can not only move back and forth in the direction of the contact force K, but also slightly tilt and move in the tolerance range.
  • the widened lower end 31 of the protective earth contact element 11 has a concave bearing surface for the spring element 32.
  • the spring element 32 is a leg spring integrally formed with a sheet metal part 34, which has a spring bow 35 and an adjoining spring arm 36.
  • contact inserts 22 with conductor contact elements 19 can be inserted into the insulating housing 18 in order in this way to provide further contact connections for current-carrying electrical lines of a current-carrying profile in addition to the protective earth contact element 11 for a protective earth line.
  • FIG. 13 shows a perspective view of the second embodiment of the protective earth contact 1 from FIG. 11 and 12 with its 3-part construction. It can be seen that in the support plane 3 of the sheet metal element 2, a plug-in opening 33 is provided with spring tabs, in which a tongue 38 of the spring element 32 is inserted. It is also clear that on this spring element 32, a conductor connection contact 13 is formed in the form of a FederklemmanBankes with two obliquely facing each other exhibited clamping legs 15. Furthermore, integrally formed with the sheet metal part of the spring element 32 is a U-shaped bent leg spring, on which the protective earth contact element 11 is supported.
  • the sheet metal element 2 can be designed so that 3 plug-in receptacles or plug-in openings 33 is disposed on opposite outer areas of the support surface. In this way, the position of the spring element 32 and the protective earth contact element 11, if necessary, be adapted depending on the intended plug alignment. It is also possible to use two spring elements 32 so as to provide a redundant protective earth contact with two protective earth contact elements 11.
  • FIG. 14 shows a perspective view of the sheet metal element 2 for the protective ground contact 1 FIG. 13 , In this case, the openings 37 in the support plane 3 are still visible, which are provided for non-positive or positive fastening of the sheet metal element 2 to an insulating housing 18 of a Abgriffsteckverbinders 17.
  • FIG. 15 shows a perspective view of the spring element 9 and the separate protective earth contact element 11 for the further embodiment. It is clear that the spring element 9 is integrally formed from a sheet metal part 34. A tongue 38 protrudes from the central portion of the sheet metal part 34. The tongue 38 has a raised portion 39 to optimize the Federkraftklemmung to the spring tabs of the insertion opening 33. The raised portion 39 also forms a stiffening of the tongue 38 from.
  • clamping legs 15 of the conductor terminal 13 are simply formed as bent from the central portion of the sheet metal part 34 material lids and aligned obliquely facing each other.
  • the leg spring 32 is also formed from a bent from the central portion of the sheet metal part 34 sheet metal portion. The free end is convex so that the concave support surface 31 of the protective earth contact element 11 is supported there.
  • FIG. 16 shows the representation of the spring element 32 with the protective earth contact element 11 FIG. 15 from the other side. It is again clear that the clamping legs 15 are issued obliquely assigning zu josd so as to form a spring clamp connection for an electrical conductor 16.
  • a locking tab 40 is issued from the central portion of the sheet metal part 34 obliquely outward.
  • FIG. 17 shows a perspective view of a Abgriffsteckverbinders 17, which is placed on a current-carrying profile 41.
  • the current-carrying profile 41 has electrical conductors 42, for example in the form of conductor bars, which are arranged alternately offset in grooves 43 in the illustrated embodiment on two levels and extend parallel to each other in the longitudinal direction.
  • the current-carrying profile 41 is arranged in a carrier element 44. It is latched with locking tabs 45 on locking contours 46 of the support member 44.
  • the support member 44 is formed as a metal trough, which extends in the longitudinal direction and on the side opposite to the bottom surface 47 with the current-carrying profile 41 lying thereon, an opening. This opening can be covered with a cover part 48 of the support member 44.
  • the tap connector 17 then rests with its support feet 26 on the cover part 48. It can be seen that the side walls 49 of the cover part 48 have U-shaped folded over edge edges 50.
  • the tabs 5a, 5b of the protective earth contact 1 are resiliently seconded between the bottom of the cover part 48 and the folded-over edges 50.
  • the resilient contact tongues 8 of the tabs 5a, 5b extend obliquely to the support surface of the cover member 48 and lie there on.
  • the tapping connector 17 is latched to the lid member 48 and the protective earth contact 1 is electrically connected to the lid member 48 to provide a protective earth for the support member 44.
  • the outer corners 6 of the straps 5a, 5b which are bent away towards the outside from the support plane 3, provide a contour issued for contacting the carrier element 44.
  • the tabs 5a, 5b dig with their flared corners 6 in the sheet material of the side walls 50 of the cover part 48 of the support member 44 a.
  • bundles of electrical conductors 51 are inserted into a respective trough formed by the tabs 5a, 5b and the side webs 4a, 4b of the sheet metal part of the protective earth contact 1 which are connected to a bend.
  • the troughs are also limited by the support feet 26, on which the bundles of electrical conductors 51 can rest laterally.
