Definitions

  • the invention relates to a distributor arrangement for telecommunications systems with a protective plug for a contact component, which is provided with connecting elements for incoming and outgoing electrical lines.
  • Such a protective plug is such. B. become known from DE-OS 30 14 796.
  • This protective plug is provided with tongues that can be inserted into a terminal block, as z. B. is shown in DE-OS 27 25 551.
  • Such a terminal block has corresponding spring contacts which are connected to the electrical lines.
  • the protective plug is equipped with surge arresters that are connected to the tabs.
  • the other pole of the surge arrester is connected to an earth rail, which has lateral contact tongues that are similar in type and size to the plug tongues. The earth potential of the earth rail is apparently supplied via these contact tongues.
  • the protective plug is only a holder for the surge arresters that are used in the contact component.
  • the earth rail is connected to an earthed mounting rail for the contact component via a bow-shaped leaf spring.
  • Such a protective plug has the disadvantage that the entire plug must be removed in the event of a surge arrester exchange, so that the lines are not protected for this time.
  • the object of the invention is to supply the protective plug with the earth potential in the simplest and safest possible way.
  • the grounding contact can rest directly on corresponding contact surfaces of the carrier part. But it is also conceivable that the carrier part with z. B. to provide a contact foil of higher contact quality and to contact with the ground contact of the protective plug.
  • the protective plug can also be contacted with a carrier rail which is arranged on the other side of the contact component.
  • FIG. 1 The development according to claim 6 is based in particular on one Contact arrangement from the z. B. has become known from DE-OS 36 25 476.
  • Fig. 1 is a flat protective plug with overvoltage protection elements to protect subscriber lines, which are connected on the front to connection elements of a shift distributor.
  • the connection elements are in turn connected to the protective modules via plug contacts.
  • a curved carrier plate has stamped-out spring legs 21, between which the protective plug with a contact zone 22 is inserted.
  • the contact zone is electrical with the z. B. connected as a surge arrester formed protective elements so that occurring surges can be derived from the grounded carrier plate.
  • the contact points of the spring legs are spherical, so that there is a relatively small point-like contact surface.
  • the outer lines of a telecommunications system can come into contact with different levels of overvoltage.
  • Modern electronic switching devices are already sensitive to low overvoltages, which have to be derived just as reliably as very high overvoltages. It is important that the contact not only can withstand strong overcurrents, but also has a low contact resistance for low overcurrents.
  • both high and low overvoltages can be carried out with little design effort can be derived in a repeatable manner.
  • the ground contact designed as a double contact has both a small-area and a large-area contact point.
  • the small-area contact point has a low contact resistance due to the high surface pressure, even with less noble surfaces. Large overcurrents are distributed over a larger area at the large contact point. The higher specific contact resistance there does not impair the derivation of high overvoltages.
  • a contact component 1 is provided with concealed connection elements 2 for incoming and outgoing lines of a telephone exchange.
  • the contact component 1 has contact springs 3 connected to the connection elements 2, which serve as mating contacts for plug contacts of a protective plug 5 designed as tongues.
  • the tongues 4 are connected to contact parts (not shown in more detail), each having a pole of a surge arrester 6, the other pole of which rests on a grounding plate 7 of the protective plug 4.
  • the grounding plate 7 is bent at right angles to both ends of the protective plug 5 in the plugging direction and projects significantly beyond the tabs 4. With its free end, it forms a ground contact 8, which is electrically connected to a grounded carrier part 9 for the contact component 1.
  • the finger-like end of the grounding plate 7, which is designed as a ground contact 8, is bent back at an acute angle and forms two spring legs 13, 14 which are resiliently braced against one another in a rectangular opening 10 in the rail-like carrier part 9. (Fig. 3).
  • the carrier part 9 is bent into an angle rail, one leg 16 of which extends in the plugging direction of the grounding contact 8.
  • the opening 10 is in the area of the turn.
  • the punched opening 10 extends from the bending edge essentially into the other leg 15.
  • the ground contact 8 protrudes considerably through the opening 10 and lies with one leg on the spring leg 14 of the carrier part 9 extending in the plug-in direction over a large area.
  • the other spring leg 13 of the grounding contact 8 lies on the opposite inner edge of the opening 10 over a small area.
  • the contact component 1 has a groove-like guide channel 11 for the ground contact 8, so that it is protected against kinking and touching.
  • the housing of the protective plug 5 has a projection 12 which covers the foot of the grounding contact 8 and can be inserted with little play into the guide channel 11 of the contact component 1.
  • the projection 12 and the guide channel 11 are chamfered at an acute angle to the direction of insertion, which facilitates the assembly of the two parts.
