Definitions

  • the invention relates to a plug insert for a metal tube housing, comprising a contact carrier, from which plug pins protrude from a first side and solder connections from a first opposite second side, a protective sleeve which can be inserted into the metal tube and surrounds the contact carrier in the final assembled state and which is made of electrically non-conductive material extends from the first side of the contact carrier in a first direction parallel to the connector pins with its front side and in a second direction, opposite to the first, forms a protective collar projecting beyond the second side of the contact carrier.
  • Such a plug insert is known from DE-A-37 27 375.
  • the contact carrier is formed in one piece with the protective sleeve and the protective collar extends in the second direction by the same distance as the solder connections in order to make it possible to solder cables to these solder connections.
  • Such plug inserts are provided in particular for metal tube housings with an inner diameter of less than 12 mm, so that due to the spatial confinement of the plug insert according to the prior art the protective collar may only extend to the end of the solder connections in order to still allow cables to be soldered to these solder connections.
  • a connector in which a contact carrier is held between an inner sleeve and an intermediate sleeve which can be screwed to it.
  • the invention is therefore based on the object of improving a plug insert of the generic type, in particular for metal tube housings with small diameters, preferably for metal tube housings with an inner diameter of 12 mm or less, in such a way that this also can be used for high insulation voltages, in particular insulation voltages of 250 V and more.
  • the protective sleeve is designed as a one-piece part, in that the protective sleeve and the contact carrier are two parts which can be assembled, in that the protective sleeve has a receptacle in which the contact carrier can be inserted and fixed and that when the contact carrier is inserted into the protective sleeve, the protective collar projects beyond the solder connections in the second direction.
  • the protective sleeve extends in the first direction at least up to one end of the connector pins. It is even better if it extends beyond this.
  • the protective collar can in principle protrude as far beyond the solder connections.
  • a solution is particularly preferred in which the protective collar projects beyond the solder connections by at least 5 mm.
  • the contact carrier can be insertable into the protective sleeve from both sides.
  • the contact carrier can be inserted into the protective sleeve from the front side.
  • the contact carrier has an annular recess facing the protective sleeve and open towards the second side.
  • the contact carrier can be fixed in a particularly defined manner if the collar has a conical seat. It is therefore also correspondingly advantageous if the recess has a conical ring wall corresponding to the seat.
  • solder connections on the contact carrier it has proven to be particularly advantageous if, starting from the second side of the contact carrier, the solder connections are freely accessible in the second direction and perpendicular to it.
  • the contact carrier is preferably designed in such a way that it extends in the second direction to a surface defined by the second side, that is to say that it has no regions which protrude beyond the second side.
  • the protective collar 52 completely lines the metal tube housing over its entire extension in the second direction.
  • the protective sleeve and the contact carrier are made of a non-conductive material, preferably of plastic.
  • An exemplary embodiment of a plug insert according to the invention for a cylindrical metal tube housing 10 comprises a cylindrical protective sleeve 14 which can be inserted into this from a front end 12 of the metal tube housing 10 and which has a front collar 18 which, when inserted, rests on an end face 16 arranged at the front end 12 in the inserted state.
  • This collar 18 is preferably provided with an outer diameter identical to the metal tube housing 10. This collar 18 defines the position of the protective sleeve 14 in the inserted state shown in FIG. 1.
  • the protective sleeve 14 is shaped in the manner of a cylinder jacket and has a cylindrical inner wall surface 20.
  • a contact carrier designated as a whole by 22 can be inserted from the side of the collar 18, which comprises a contact carrier plate 24 which, when inserted into the protective sleeve 14, has a first side 26 facing the collar 16 and a second side facing away from the collar 16 Page 28. Furthermore, on the first side 26 of the contact carrier plate 24, a cylindrical projection 30 protrudes in the direction of the collar 18, which is integrally formed on the contact carrier plate 24 and together with this forms a cylindrical outer surface 32 with which the contact carrier 22 on the inner wall surface 20 of the Protective sleeve 14 is guided.
  • the protective sleeve 14 has an annular collar 33 projecting inwards from the inner wall surface 20, which has on its side facing the collar 18 a conical ring surface 34 falling towards the inner wall surface 20 and additionally an inner surface parallel to the inner wall surface 20 36.
  • the contact carrier plate 24 is shaped accordingly. It has an adjoining the cylindrical outer surface 32, a conically radially inwardly extending ring surface 38 which can be brought into contact with the annular surface 34, and an adjoining the annular surface 38 and on the inner surface 36, the outer surface 40 holding the contact carrier plate 24 centered.
  • the contact carrier 22 can thus be inserted into the protective sleeve 14 from the collar 16 until the annular surface 34 and the annular surface 38 come into contact with one another.
  • the position of the contact carrier 22 is determined by plug pins 42 which extend from the first side 26 away from the contact carrier plate 24 and which should extend to the collar 18 and preferably end directly in front of a front side 44 of the protective sleeve 14.
  • the connector pins 42 extend parallel to a longitudinal axis 46 of the metal tube housing 10 and the protective sleeve 14 in a first direction 45, while the solder connections 48 extend opposite to the first direction 45 in a second direction 47 parallel to the longitudinal axis.
  • a protective collar 52 covering the entire inner wall surface 20 also extends in this direction.
  • solder pins 48 assigned to the plug pins 42 rise, to which the connecting cable 50 which leads the metal tube housing and is only shown in broken lines can be soldered.
  • the protective collar 52 is formed by the section 52 of the protective sleeve 14 which extends in the second direction 47 from the second side 28 and which is intended to prevent flashovers from the solder connections 48 to the metal tube housing 10, the protective collar 52 an air gap L leading from a rear end 54 of the solder connections 48 to the metal tube housing 10 is to be kept as large as possible.
  • the air gap L is more than 5 mm.
  • the protective collar 52 thus extends at least 5 mm from the rear end 54 of the solder connections 48 away from the second side 28 in the direction of the longitudinal axis 46.
  • the plug insert according to the invention is now assembled by first soldering the cables 50 to the solder connections 48 when the contact carrier 22 is not inserted into the protective sleeve 14, and then inserting the contact carrier 22 from the collar 18 into the protective sleeve 14 and on the collar 32 is preferably fixed by press fitting, as shown in Fig. 1.
  • a snap-in connection can be provided, for which purpose the contact carrier plate is preferably provided at the level of the second side 28 with radially outwardly projecting claws 60 which engage in corresponding recesses 62 in the inner surface 36 of the collar 32 and thus prevent the contact carrier plate 24 from moving in the direction of the collar 18.
  • the contact carrier 22 is welded to the protective sleeve 14 in the contact area of the Inner wall surface 20 facing outer surface 32 of the cylindrical projection 30 with the inner wall surface 20 of the protective sleeve 14, wherein a weld 66 is formed, which preferably runs around the inner wall surface 20.
  • the protective sleeve 14 is made of a translucent or transparent material.
