Definitions

  • the invention relates to a method for the electrically conductive connection of two electrical lines, each of which has at least two mutually insulated electrical conductors and a common sheath surrounding the same, and of which one line equipped with insulated conductors is flexible while the other is rigid , tubular metal jacket.
  • Cables with a rigid, tubular metal jacket can be used in areas where high temperatures, for example 700 ° C, prevail. They have to remain stable at such high temperatures so that, for example, signal transmission is possible without interference.
  • a special area of application for such lines is the so-called “lambda probe”, with which the catalysts of motor vehicles are monitored.
  • the probe is connected here to electrical conductors of the line, which are embedded in a steel tube serving as a metal jacket with the interposition of high-temperature-resistant insulating material.
  • temperature-resistant flexible lines are used, the conductors of which are connected in an electrically conductive manner to the conductors of the rigid line.
  • the flexible cables not only have to be temperature-resistant, they also have to be moisture-proof, as they have to remain functional in all kinds of weather conditions appropriate motor vehicle is suspended. This also applies to the connection point between the two lines.
  • the invention has for its object to design the method described above so that a moisture-proof connection point between the two lines can be made in a simple manner.
  • the exposed conductors of both lines can be connected to one another using conventional technology. For example, they are welded to one another directly or with the interposition of contact elements.
  • the conductors of the flexible line are guided separately in the sealing body and kept at a distance.
  • the metallic sleeve is finally pressed on, not only is the entire connection point sealed to the outside, but also the end of the flexible line.
  • the rubber-elastic sealing body is pressed so that it lies tightly and tightly against the insulation of the conductor. Moisture can therefore not reach the connection point via the core of the flexible line.
  • the two lines 1 and 2 to be connected to one another each have, for example, four electrical conductors 3 and 4.
  • FIG. 1 only two of the conductors 3 and 4 are shown.
  • Lines 1 and 2 have at least two conductors. But it can also be three or more conductors.
  • the line 1 is designed as a flexible, temperature-resistant line.
  • Their conductors 3 are each surrounded by temperature-resistant insulation 5, which consists, for example, of polytetrafluoroethylene (PTFE). All insulated conductors 3 are surrounded by a common sheath 6, which also consists of a temperature-resistant material, such as PTFE.
  • the insulated conductors 3 can be stranded together and have an extruded sheath. However, according to FIG. 2, they can also be relatively loose individually be arranged in a tubular jacket 6. For the connection to the line 2, the jacket 6 at the end of the line 1 is removed to a suitable length according to FIG. The ends of the conductor 3 are also stripped.
  • the four conductors 4 of line 2 consist, for example, of a chromium-nickel alloy. They are embedded at a distance from one another in insulating material 7, which is, for example, magnesium oxide.
  • the insulating material 7 is surrounded by a tubular metal jacket 8, which consists for example of stainless steel.
  • conductors 4 protrude from metal jacket 8.
  • a measuring device 9 is connected to it, for example a lambda probe.
  • a rubber-elastic sealing body 10 shown in FIGS. 4 and 5 is first pushed onto the conductor 3 until it is insulated 5.
  • the sealing body 10 is prefabricated.
  • it is made of silicone rubber.
  • it has four separate through holes 11 for receiving the four conductors 3 separately.
  • a circumferential collar 12 with an enlarged diameter can be attached to the sealing body 10, from which the sealing body 10 protrudes in both directions.
  • the sealing body 10 has an adapted number of through holes.
  • the conductors 3 of the line 1 protruding from the sealing body 10 are then electrically conductively connected to the conductors 4 of the line 2.
  • the conductors 3 and 4 are preferably welded to one another, for example by means of a laser beam or inductively.
  • a sleeve 13, for example made of stainless steel, is then pushed over the connection point shown in FIG. 6.
  • the sleeve 13 can finally be pressed together at both ends. It then lies on the one hand on the metal jacket 8 and on the other hand the sealing body 10 firmly and moisture-proof.
  • the sealing body 10 is pressed together so that it also surrounds the conductors 3 in the area of their insulation 5 in a moisture-tight manner.
  • the conductor 3 remain unchanged separately.
  • the soul of line 1 is sealed moisture-tight in this way.
  • contact elements can first be attached to the conductors 3 before welding, for example by striking.
  • the conductors 4 are then welded to the contact elements.
  • the contact elements can for example be tubular or flat U-shaped.
  • the sealing body 10 Before the sleeve 13 is attached, the sealing body 10 can be displaced on the conductors 3 in such a way that it projects at least partially over the connection points 14 between the conductors 3 and 4 or between the contact elements and the conductors 4.
  • the sealing body 10 can have a recess 15 extending in the axial direction, into which one of the connection points 14 projects. As a result, it is positioned more precisely and secured against twisting.
  • the tubular jacket 6 of the line 1 can be pushed onto the shoulder of the sealing body 10 projecting from the collar 12 in this direction before the sleeve 13 is pressed.
  • a shrink tube can also be shrunk onto the line 1, which at least protrudes beyond the collar 12 of the sealing body 10, but can also rest against the sleeve 13.
  • a sealing body 10 which is configured differently from FIG. 4 is used.
  • the sleeve 13 is also designed differently. The connection between the conductors of the two lines 1 and 2 and the function of the sealing body 10 and sleeve 13 remain unchanged compared to the method already described.
  • the prefabricated sealing body 10 according to FIG. 8 is surrounded by a collar sleeve 16 at its end facing the line 2 in the assembly position. It is captively attached to the same during the manufacture of the sealing body 10.
  • the circumferential collar 17 at the end of the sealing body 10 is used for this purpose.
  • the collar sleeve 16, like the sleeve 13, can be made of chromium-nickel steel. It is essentially cylindrical and has a flanged edge 18 at its end facing away from line 1.
  • the end of the sleeve 13 which is pressed around the sealing body 10 when the connection point is completed is bent radially inwards when it is being eaten in accordance with FIG. 8 until it rests on the collar sleeve 16.
  • forces acting on the sealing body 10 in the radial and, because of the collar 18, also in the axial direction are exerted, as is shown in FIG. 8 with two arrows.
  • the sealing body 10 is thereby compressed in the desired sense.
  • the design of the sleeve 13 lies close to the metal jacket 8 of the line 2. It can also be glued to the same.
  • a flexible line 1 is used, which is surrounded by a metallic screen 19.
  • a mesh made of chrome nickel is preferably used as the screen 19, which can also take on the function of a reinforcement.
  • the collar sleeve 16 is only pushed onto the sealing body 10 when the same is brought into its assembly position. Before the collar sleeve 16 is pushed onto the sealing body 10, the screen 19 is placed around the latter. The collar sleeve 16 then fixes the screen 19 on the sealing body 10.
  • the metallic screen for the entire connection point is produced without gaps when the sleeve 13 is pressed around the collar sleeve 16, as is described for FIG. 8.
