Definitions

  • the invention relates to a cable feedthrough according to the preamble of patent claim 1 and a method for the production thereof according to claim 12.
  • Such a cable bushing is known from DE 37 42 731 C2.
  • the individual wires of a cable are held by a spreading member made of plastic at a distance and encapsulated in a mold with a plug made of relatively soft polyurethane. Then a housing made of harder plastic is injected over this plug.
  • DD 222 169 A5 describes that a sleeve housing surrounding a conductor ends is filled up with a liquid filling material (casting resin) from the outside.
  • the object of the invention is to provide an improved cable feedthrough and a method for its production.
  • Fig. 1 is a schematic overall view of a built-in wall of a vehicle part cable gland
  • Figure 2 is an overall perspective view of the grommet in a finished but unassembled condition.
  • FIG. 3 shows a side view of the cable feedthrough according to FIG. 2;
  • Fig. 4 is a perspective view of the first shell of the housing of the cable gland
  • FIG. 5 shows a perspective view of the second shell of the housing of the cable bushing
  • Fig. 6 is a perspective view of the assembled cable entry from the entrance side
  • FIG. 7 is a view of the cable gland with latched shells of the housing, but without plastic encapsulation.
  • FIG. 8 shows the cable bushing according to FIG. 7 with plastic encapsulation with a separate web after the leak test.
  • the vehicle part 1 schematically indicated in FIG. 1 has a wall 2 with a passage opening 3, into which a cable feedthrough designated as a whole by 4 is inserted.
  • the cable feedthrough 4 has a housing 31 which is formed by a first shell 5 shown in FIG. 4 and a second shell 6 shown in FIG.
  • the first shell 5 and the second shell 6 each have an angular course. They are designed as half shells and form an inner cavity through which a plurality of strands 16, 17, 18, 19 exhibiting cable is guided from an inlet side 29 to an outlet side 30 therethrough. At the inlet side 29 is in both shells 5 and 6, a groove-shaped receptacle 7 for a the cable surrounding corrugated pipe 20 is formed. In this recording 7, the end of the indicated in Figure 1 corrugated pipe 20 is inserted before connecting the two shells 5 and 6.
  • the two shells 5 and 6 have latching means 9 and 10, respectively, after insertion and fixation of the cable or the strands 16, 17, 18, 19 provided in holders 8 for a positive locking of the two shells 5 and 6.
  • the latching means 9 and 10 are preferably designed as latching hooks provided with chamfers and correspondingly shaped for their reception locking surfaces, so that the joining of the two shells 5 and 6 takes place in a simple manner by squeezing.
  • a guide post 21 is additionally formed in the center of the cavity of the first shell 5 at this point.
  • the first shell 5 and the second shell 6 also have in the entire angled region in the circumferential direction extending grooves 22, which serve to increase the surface area and to better adhesion of the injected into the cavity plastic material.
  • a stop angle 11 is formed on the side facing the outlet side 30, which has a first leg 12 formed perpendicular to this leg and a second leg 13 formed parallel to this leg. Further, a detent stop 14 is provided on the outside of the outlet side 30 toward the side facing the second shell 6, which as an annular collar or as a latching hook with is formed to the outlet side 30 toward reduced diameter. Between the outside of the side facing the outlet side 30 and the leg 13 of the stop bracket 11, a releasable web 15 is further provided which is provided with predetermined breaking points and therefore after successful testing of the tightness and the insulating capacity of the cable gland 4 before inserting in the passage opening 3 can be separated.
  • the stop angle 11 with two legs 12 and 13 engages the wall 2 of the vehicle part 1 from the outside.
  • the stop bracket 11 thus simultaneously forms an axial stop from the outside on the wall 2 and a rotation.
  • the second axial stop is formed by the latching stop 14, the end face of which facing the bending region, after insertion of the cable feedthrough 4 into the passage opening 3, bears against the inside of the wall 2.
  • the first shell 5 and the second shell 6 are joined together and squeezed by the Locking means 9 or 10 locked together.
  • the cable feedthrough 4 which corresponds in its outer contour to the representation in FIG. 7, is then inserted into a mold which surrounds the bending region at a small distance. Subsequently, plastic material is injected into injection ports 28, which are provided near the outlet side 30 on the housing 31.
  • the plastic material first fills the inner cavity of the two shells 5 and 6 and thereby forms at least one inner seal 23, which seals the strands 16, 17, 18, 19 with each other and against the inside of the shells 5 and 6 respectively. Subsequently, the plastic material passes through connection openings 32 (see Figure 5) to the outside and fills the cavity of the mold between see their inner wall and the outer walls of the shells 5 and 6, in particular in the bending region.
  • the shells 5 and 6 are characterized by the plastic material in addition to latching by means of a Weg- going dense outer lateral surface 27 connected and surrounded.
  • an outer seal 24 is generated, which is shown in the figures in two different variants.
  • the outer seal 24 is formed by two circumferential sealing lips 26, each having the outlet side 30 towards a reduced diameter as an insertion bevel.
  • the outer seal 24 is formed by a bead-shaped contour which is similar in cross-section to an O-ring 25.
  • the outer seal 24 is located approximately in the middle between the first leg 12 of the stop bracket 11 and the locking stop 14 so that it is after the insertion of the cable gland 4 in the passage opening 3 approximately in the middle of the wall 2 and sealingly against the Wall of the passage opening 3 is present.
  • a polyamide such as Durethan AKV 30H2.0 is particularly preferably used.
  • the outer lateral surface 27 and the outer seal 24 is particularly preferably a liquid silicone rubber, such as Silopren ® LR 2750 (Silopren is a registered trademark of Bayer AG, Leverkusen) used. This has in addition to a very good electrical insulation capability also excellent permanent elasticity for the production of the inner seal 23 and the outer seal 24 and the outer circumferential surface 27.
  • the adhesion of this material to the polyurethane sheathed strands 16, 17, 18, 19 and to the material of the shells 5 and 6 is very good.
  • the high valid industrial test standards (degree of protection IP6K9K) are achieved reliably by means of the cable bushing according to the invention.
  • a thermoplastic polyurethane (TPU) can also be used if the requirements for temperature resistance and thermal shock resistance are not too high.
  • other hard plastics for the production of the shells 5 and 6 and other soft plastics for the production of the seals 23, 24 and the lateral surface 27 are suitable. Due to the clam-shell design of the housing 31, the cables or strands 16, 17, 18, 19 can be completely prefabricated (stripped, bundled, twisted and / or crimped) even before they are inserted into the cable bushing 4.
  • the cable bushing according to the invention is easy to manufacture and outstandingly suitable for process-reliable series production.
  • a clear identification mark for the successfully tested component is created before assembly. Without the detachment of the detachable web 15, the cable bushing 4 can not be mounted.
  • the angled shape of the grommet 4 in the embodiment shown is chosen only as an example and not restrictive for the subject invention.
  • the grommet 4 may also be straight, curved or designed with angles other than 90 °.
  • the housing can also be formed from three or more shell parts.
  • the shell parts can also be pivotably connected to each other, for example by means of a film hinge on a longitudinal edge, so that the shell parts by folding and locking ren, for example, at the opposite edge after inserting the cable and before the injection molding, casting or foaming be closed to produce the inner seal and the outer lateral surface.
