Definitions

  • the invention relates to an overvoltage protection plug according to the Preamble of claim 1.
  • Surge protection plugs are used in particular in telecommunications and data technology used to connect the pre-wired pair Overvoltages and currents due to technical defects or external Disorders such as To protect lightning strikes.
  • point out Plug a voltage-limiting and usually also a current-limiting Component on which a melting element, usually in the form of a solder pill, assigned. Occurs in the voltage-limiting component overcurrent lasting for a long time, the solder pill melts due to of the heat loss occurring on the component, which usually results in a mechanical fail-safe shorts the lines to earth. It is necessary as the components due to the overvoltages or currents that occur functionality may have been impaired. For simpler Identification of which fail-safes have been triggered are already very different Optical fail-safe signaling is known, although predominantly LEDs are used.
  • Solutions for direct signaling are known, in which after melting a movable pill of the fail-safe by spring force when it reaches its end position next to the contact points for the lines a and b additionally contacted another contact point for signaling.
  • the design must be such that the contact point is weakly springy for the signaling to a Avoid interference with the fail-safe movement. In any case, must be avoided be that through the third contact point at the two contact points a-earth and b-earth the contact pressure is too low or even no contacting takes place.
  • the components of the surge protective plug to arrange a circuit board. Because the optical fail-safe signaling is not Therefore, two types of printed circuit boards are always required or required manufactured, namely one with and one without optical fail-safe signaling. Due to the additional components for optical fail-safe signaling also take the geometric dimensions of the circuit board to. However, the same housing for both PCB variants To be able to use this will correspond to the larger circuit board designed. Furthermore, if the plug is arranged in a housing this be designed such that the optical fail-safe signaling is noticeable. For this purpose, the housing has an opening which can protrude the light-emitting diode arranged at the plug end to be visually perceived. With the connector variant without optical Fail-safe signaling must then be closed off this opening.
  • the invention is therefore based on the problem of an overvoltage protection plug to create, which is compact, easy to retrofit and requires only minor design changes to a housing.
  • the surge protection plug By designing the surge protection plug as a closed unit on a circuit board and arrangement of optical fail-safe signaling on a separate circuit board, which at If the first circuit board can be assigned, the result is a simple one Retrofitting for optical fail-safe signaling without subsequent Assembly of components. Since the geometric dimensions of the first circuit board are always the same, are not when used in a housing spatial reservations for optical fail-safe signaling necessary what a more compact design allows. Especially when arranging the second circuit board above the first circuit board can Components of the second circuit board in the gaps between the components the first circuit board are arranged. Another advantage is that the first circuit board is more versatile and therefore in larger quantities can be produced, which reduces their unit costs.
  • Fig. 1 is the side view of one with an overvoltage protection plug shown housing to be assembled, which is a lower housing part 1 and a housing upper part 2 comprises.
  • a first circuit board 3 On a first circuit board 3 are a Three-pole surge conductor 4 as voltage-limiting and two PTC resistors 5 arranged as current-limiting components.
  • the surge conductor 4 and the PTC resistors 5 are cylindrical and arranged in grooves and / or slots in the printed circuit board 3 where this then e.g. be electrically connected by means of reflow soldering. After soldering the surge arrester 4 and the PTC resistors 5 a fail-safe contact 6 is snapped onto the surge arrester 4, with an additional fixation of the fail-safe 6 via a Slit in the circuit board 3 takes place.
  • the fail-safe contact 6 is via the Center electrode of the surge conductor 4 permanently with the earth potential connected. Between the surge arrester 4 and the fail-safe contact 6, a melting element designed as a solder pill 7 is arranged, that is firmly connected to the fail-safe contact 6. If the Surge arrester 4 melts the solder pill 7, and that in the normal state preloaded shorting bar of fail-safe contact 6 moves to left to the surge arrester 4, with the shorting bar in the relaxed Condition of the two outer electrodes of the surge arrester 4 contacted. As a result, however, the two outer electrodes also rest Earth potential and a double wire connected to the external electrodes. Furthermore, a resilient earth contact 8 is arranged on the printed circuit board 3, via which the earth potential of the circuit board 3 is supplied.
  • the resilient Earth contact 8 is arranged outside the housing, so that this is relatively freely accessible. Therefore, it can form an earth rail 19 contacting counterpart e.g. as a tab from the assembly tub of a distributor can be bent out in a production-friendly manner.
  • the circuit board 3 is an opening 9 in the middle, which the pulling of Printed circuit board 3 allows using an associated tool Tool through an opening 18 in the lower housing part 1 in the Interior of the housing can be performed.
  • the circuit board 3 becomes Installation pressed into the lower housing part 2 and is with this connected with a snap. When inserted, the circuit board 3 is on the Bottom completely covered by the lower housing part 1, so that an additional passivation to protect the conductor tracks against contact and damage can be eliminated.
  • the optional optical fail-safe signaling is indicated by a second circuit board 10 realized.
  • a light emitting diode on the printed circuit board 10 11, a current limiting resistor 12, an operating voltage contact 13 and a connection contact 14 is arranged.
  • the operating voltage contact 13, like the earth contact 8, is resilient and extends out of the housing upper part 2, so that its too contacting counterpart also by bending a tab in a signal plate 20 carrying the operating voltage are produced can.
  • the formation of the earth contacts 8 and the operating voltage contacts 13 allows up to 200 pairs to be connected at the same time by means of a sheet without additional intermediate pieces.
  • connection contact 14 provides 6 when the fail-safe contact is triggered Connection between the first circuit board 3 and the second circuit board 10 ago.
  • the connection contact 14 is biased against the solder pill 7, an insulation layer between solder pill 7 and connection contact 14 15 is arranged.
  • the circuit of the light emitting diode 11 is open. Now the solder pill melts 7, the biased connection contact 14 moves in the direction Fail-safe contact 6 and contacts it below the solder pill 7 and Insulation layer 15 by a curved projection. Because fail-safe contact 6 and connecting contact 14 move in the same direction, there is no optical fail-safe signaling Attenuation of the actual fail-safe process.
  • the circuit board 10 like the circuit board 3, snaps into the upper housing part 2 pushed in.
  • the circuit board 10 is behind a projection 16 pushed and pushed upwards, where this by a widespread Latch 17 is held.
  • the upper housing part 2 is at least partially transparent, so that the optical fail-safe signaling is perceptible outside the housing. Because of the mechanical Protection of the light emitting diode 11 by the housing can be used as be formed laterally emitting SMD diode.
