Definitions

  • the invention relates to a method for assembling an arrangement of a connector having a contact carrier at one end of a cable, according to the features of the preamble of patent claim 1 .
  • FIG. 9 shows an arrangement 1 of a plug connector 3 having a contact carrier 6; 4 according to the prior art. In this arrangement, at each end of the cable 2 and adjusting the position of the connector 3; 4 to the position of the electrical conductors 21, 22 of the cable 2 on which the connector 3; 4 is connected
  • the alignment of connector 3 (on one side or at one end of the cable 2) to connector 4 (on the other side or at the other end of the cable 2) doesn't match.
  • the orientation specification of the arrangement to be assembled with plug connectors (line) arranged on the cable cannot be adhered to and leads to problems during final assembly.
  • the wiring harness must be twisted as required so that it can be plugged into the respective mating connector/unit connection.
  • the respective plug connector (socket plug) cannot be twisted relative to the line (to the cable).
  • the invention is therefore based on the object of providing a method with which the two connectors arranged at the end of the cable can be aligned with one another.
  • the position of the plug connector is adjusted to the position of the electrical conductors of the cable to which the plug connector is connected, before the cable is pressed with a sleeve that partially encloses the contact carrier during the assembly process, by correcting the alignment of the plug connector ,
  • the mounted contact carrier must be twisted relative to the electrical conductor, which results in a flashover of the electrical conductor as a result of this twisting, which leads to a reduction in length between the contact carrier and the end of the cable.
  • the alignment of the plug connector can be corrected during the assembly process.
  • the mounted contact carrier must be rotated relative to the cable. This twisting causes the individual cables to flash over, which leads to a reduction in length between the contact carrier and the strain relief (formed by the sleeve pressed onto the end of the cable).
  • the mating face of one connector is thus aligned in the correct position with respect to the mating face of the second connector.
  • Such a ready-made arrangement can be installed in an advantageous manner as intended without any problems, since the mating faces of the mating connectors (e.g. on an electronic device, a Aggregate connection or the like) cannot be changed or adjusted due to their stationary installation.
  • a first solution is that the method is carried out without influencing process parameters and part design, so that a rotation of ⁇ 10° is permissible due to the tolerance design of the process and part tolerances.
  • the torsion can also be 25% larger or smaller ⁇ 10°.
  • a second solution is that the method is carried out with an influence on process parameters but without influence on part design, with the length reduction to be expected due to the twisting already being provided for and added to when removing (stripping) the outer sheath of the cable .
  • the influence of the provisionally longer stripping length on old intermediate steps must be considered.
  • a third solution is that the method is carried out with an influence on process parameters and influence on part design, with the maximum length reduction to be expected being provided by the maximum defined rotation of ⁇ 180° in the tolerance of the individual parts and in the process steps must become.
  • the stripping length is reduced to a dimension for all twists.
  • the strain relief must be lengthened in order to absorb the changes in length caused by twisting.
  • the sleeve (particularly the shielding sleeve) must also be adjusted to ensure all possible crimping positions. If necessary, the position of the compression stamp must also be adjusted.
  • the sleeve is designed as a shielding sleeve made of an electrically conductive material (as already mentioned in some cases above) and is pressed onto the cable via a shield, in particular a shielding braid.
  • the shielding of the cable to the contact carrier and/or a mating connector into which the connector is plugged is contacted by the shielding sleeve, so that a continuous shielding is realized via a plugged-in connector.
  • the shielding of the cable in cooperation with the sleeve (shielding sleeve) can provide strain relief in order to absorb tensile and compressive forces acting on the connector and/or the cable.
  • Figure 1 shows an arrangement 1 and its assembly.
  • the arrangement 1 comprises a cable 2, here with two electrical conductors 21, 22.
  • the number of electrical conductors in the cable can also be greater.
  • a contact partner 5 is arranged, for example clamped, at the end of the respective electrical conductors 21 , 22 .
  • Each contact partner 5 is placed in its associated contact chamber within a contact carrier 6 deployed.
  • the contact carrier 6 in turn is inserted into a housing which forms the first plug connector 3, although this is not shown in FIG. 1 but is implemented in practice. This configuration can be seen in the upper representation of FIG.
  • FIG. 1 is a Twisting by plus/minus 10° permissible. In practice, this twist can also vary by plus or minus 25%.
  • FIG. 2 shows how the method is carried out according to the second solution, in which the process parameters have an influence when the method is carried out, but the part design is not taken into account.
  • the length reduction to be expected due to the twisting between the contact carrier 6 and the cable 2 must already be provided for and added to the removal of the outer sheath of the cable 2 . Reference is already made to FIG. 5 in this regard.
  • FIG. 3 shows how the method is carried out according to the third solution, in which the process parameters and the part design have an influence on how the method is carried out.
  • the maximum length reduction to be expected due to the maximum defined rotation of plus/minus 180° must be provided for in the tolerance of the individual parts and the process steps. It is essential that the length of the stripping is reduced to a dimension for all twists.
  • the strain relief formed by the area of the sleeve 7 that is pressed onto the end of the cable 2 must be lengthened in order to absorb (compensate for) the changes in length caused by the twisting.
  • the sleeve 7, in particular the sleeve designed as a shielding sleeve must also be adjusted to ensure possible pressing positions, in particular shield pressing positions.In addition, the position of the stamp for pressing the sleeve 7 must be adjusted
  • Figure 4 shows experiments made to evaluate the change in length by twisting through 180°.
  • measurement tests were carried out on two different cable types carried out (30 measurements per line type). The measured values are listed in the tables shown. Maximum values of both tests are highlighted in dark red (maximum 1.626 mm).
  • the measured values vary greatly, ie there is no linear relationship between the change in length and the angle of twist.
  • the values given in the tables are examples of a specific exemplary embodiment, but are not limited to this, so that they can also vary upwards and/or downwards depending on the part design.
  • FIG. 5 shows the arrangement of the contact partner 5, which has been attached to an electrical conductor and has already been inserted into its associated contact chamber in the contact carrier 6, before twisting to adapt the plug faces. It can be clearly seen that the front end of the cable 2 and the front end of the contact carrier 6 facing it are at a greater distance than is the case after adjustment of the connector faces by twisting. This means that this distance has become smaller after the rotation and must therefore be taken into account. This can be seen very clearly in the lower illustration in FIG.
  • a change in length of, for example, 2 mm (millimeters) is provided.
  • the strain relief is extended by 2 mm, for example (component).
  • the stripping length is shortened by 2 mm, for example (process).
  • the position of the compression, in particular the screen compression is offset by 2 mm, for example.
  • the press stamp for pressing the sleeve 7 in particular the shielding sleeve
  • the press stamp for pressing the sleeve 7 must be shifted, for example 2 mm, in the direction of the connector face (connector interface). In the tolerance calculation, it was ensured that the press stamp (despite the changed geometry and taking into account the change in length) sits completely over the strain relief and thus presses sleeve 7 (shield sleeve) cleanly.
  • FIGS. 1-10 An extract from the processing specification relating to the third solution is shown in FIGS.
  • FIG. 9 shows an exemplary embodiment according to the prior art.
  • the arrangement 1 comprises a cable 2, the length of which is chosen according to its purpose.
  • a first connector 3 and a further connector 4 is arranged at the respective end of the cable 2.
  • the cable 2 comprises two electrical conductors 21, 22, it being possible for the cable 2 to be unshielded or shielded.
  • Both the first and the second connector 3, 4 comprise a contact carrier (provided with the reference number 6 in the preceding figures), with a first contact partner 31 and a further contact partner 32 of the first connector as well as a first contact partner 41 and another contact partner 42 of the other connector 4 are used.
  • These contact partners referred to above are electrically attached to the respective end of the first electrical conductor 21 or the further electrical conductor 22 .
  • the number of electrical conductors or their contact partners can also be larger.
  • the method according to the invention which is shown, for example, in alternatives in FIGS. 1 to 3, is fundamentally based on the arrangement 1 as shown in FIG.

Abstract

L'invention se rapporte à un procédé d'assemblage d'un système (1) d'une fiche de connexion (3 ; 4) comprenant un support de contact (6) à une extrémité d'un câble (2), la position de la fiche de connexion (3 ; 4) étant réglée à la position des conducteurs électriques (21, 22) du câble (2) auquel la fiche de connexion (3 ; 4) est reliée avant que le câble (2) soit ajusté par pression à un manchon (7) qui entoure partiellement le support de contact (8), pendant le processus d'assemblage par correction de l'alignement de la fiche de connexion (3 ; 4). À cet effet, le support de contact (6) monté doit être tourné par rapport aux conducteurs électriques (21, 22) ; cette rotation amène les conducteurs électriques (21, 22) à être retournés, ce qui provoque une réduction de longueur entre le support de contact (6) et l'extrémité du câble (2).
