Definitions

  • the invention relates to a protective assembly for connection to a contact component of a distributor in a telecommunications system.
  • Such a protective assembly is e.g. through the DE 25 08 845 B2 become known. Then the protective assembly points a flat carrier part for a multitude of two-pole Surge arresters arranged in a row are and rest on contact parts of the support part with a pole. The contact parts end at the front in contact points, which can be contacted with plug contacts of the contact component are.
  • the carrier part is from the back of an attached U-shaped grounding plate that gripped to the front pointing spring tongues on the other Poles of the overvoltage conductor are under prestress and press them against the contact parts of the carrier part.
  • the problem arises that the free ends of the spring tongues projecting in the sliding direction Trigger on the above surge arresters and are difficult to lift or push over can.
  • the invention has for its object to postpone the To facilitate grounding sheet.
  • FIG. 1 shows a distributor block 1 with a carrier part 2, in which disk-like wire guides 3 and contact components 4 are stacked on top of each other in a sandwich.
  • the wire guides 3 have arcuate wire guide channels 5, in which incoming and outgoing lines (17, Fig. 2) from Side walls 6 to an operating side 7 of the distributor block can be performed.
  • the contact components 4 are on this Provide side with insulation displacement terminals 8 in their clamping slots the incoming and outgoing lines using a connection tool 9 can be pressed in contacting.
  • the insulation displacement terminals 8 are connected to contact parts which in Inside the contact components form isolating contacts, which means Insertable disconnect plug 10 interrupted from the front can be.
  • the contact components 4 have on their operating side 7 opposite Rear 11 plug contacts for one on the side Protective assembly 12 which can be pushed into the distributor block 1. This is along the contact component 4 facing Front 13 provided with plug contact points 14, which according to the indicated arrow direction between the plug contacts of the Contact components 4 can be inserted.
  • the plug contact points 14 are Protective assembly 12 between plug contacts 15 of contact parts 16 of the contact component 4 can be inserted.
  • the contact parts are connected to the insulation displacement terminals 8 (FIG. 1) on which the incoming and outgoing lines are connected.
  • the protective assembly 12 consists of a carrier part that composed of a circuit board 17 and a frame part 18.
  • the protective assembly 12 is with power fuses 19 and two-pole surge arresters, each equipped with one of its poles connected to contact points on the circuit board are.
  • Spring tongues are located at the other pole of the surge arrester 20 21 of a grounding plate 22, which the protective assembly 12 from its rear, facing away from the plug contact points 14 encircled in a U-shape.
  • the grounding plate 22 is with its the spring tongues 21 carrying legs on the front of the frame part 18 anchored.
  • the spring tongues 21 protrude from the front forth in the direction of the back and lie with theirs free ends on the surge arresters 20. When postponed of the grounding plate 20 on the assembled protective assembly 12 the spring tongues slide flat over the surge arresters, so that the earthing plate 12 is facilitated.
  • the surge arresters are offset in two here Rows arranged so that a larger number Surge arresters with the same overall width can be.
  • the trained as a cut rag Spring tongues 21 are so short that a high pressure force can be achieved.
  • FIGS 4 and 5 are in a similar protective assembly as in Figures 2 and 3, the surge arrester 20 also divided into two rows, two each Surge arrester 20 in pairs without lateral offset are arranged one behind the other.
  • the spring tongues 21 for the front surge arresters 20 protrude from the front forth towards the back, where the spring tongues 21 for the rear surge arrester 20 from the back towards the front and to the front spring tongues 21 are arranged in pairs aligned. Since the spring tongues no longer overlap, it is possible the pitch between the surge arresters to reduce or use larger surge arresters to use cheaper features.
