Definitions

  • the invention relates to a method for producing branches on an electrical cable insulated by means of a continuous sheath.
  • Branch is to be understood to mean the creation of an electrical connection at any point of a cable insulated by means of a continuous sheath.
  • the present invention has for its object to provide a method according to the preamble of claim 1, the creation of large within wide limits Enables contact areas and keeps the stripping in a practically negligible order.
  • the solution according to the invention consists in a method of the generic type is that in the insulating sheath of the cable at the point of the junction there is an incision which enables access to the conductive core and that through this incision with friction through this access between the conductive core of the cable and the insulating sheath inserts at least one line piece such that it lies in contact in the longitudinal direction of the cable over a predetermined length with the conductive core of the cable.
  • the size of the contact surface can be adapted to the desired size in a very simple manner. Stripping work in the strict sense is not necessary. Flanging work and also welding or soldering work are not absolutely necessary here, at least in principle.
  • the cable can be expedient to bend the cable at the location of the incision in the order of magnitude of 90 °, so that the widening of the incision on the outer jacket of the sheath thereby facilitates the insertion of the conductor piece.
  • the lateral lips of the insertion incision are expanded elastically.
  • a line piece is also included used essentially rectangular cross section. Its part protruding from the cable is preferably bent over after insertion.
  • two lines are inserted through the access created in opposite directions, the two sections of which lie outside the cable and are mechanically and electrically connected to one another in such a way that the branch cannot be detached.
  • the two conductor section sections are twisted together outside the main cable.
  • the welding can be done after a local preheating by compressing the end of the conductor piece or pieces as close as possible to the branch point between two graphite electrodes, which are caused by a current of great strength.
  • Other types of welding or soldering are also possible.
  • the incision is closed by a sealant.
  • the connection zone can be easily encapsulated with a suitable material. In this case it is also possible to achieve the tightness of the connection zone by surrounding it with two insulating half-shells.
  • the incision for the insertion is made at the point of the branch, either by grinding the insulating sheath or by inserting it with a suitable tool.
  • FIG. 2 shows a section of an electrical cable 1 which has a conductive core 2, which is formed, for example, from a stranded wire 3 and which is surrounded by a continuous insulating sheath 4.
  • a cut 5 in the form of a cylindrical segment is machined into the insulating sheath 4, which gives access to the conductive core 2 and defines the lips 6 and 7.
  • the cable section according to FIG. 2 is subjected to a bend of approximately 90 ° in order to elastically remove the lips 6 and 7 from one another and thus the insertion of one or more conductor pieces that form the. Branch should facilitate. If the Ab Branch produced only by means of a single conductor piece, this is inserted into the incision 5 in a position as the conductor piece 8 shows. The end 10 of this conductor piece is then bent upwards and then assumes the position shown in FIG. 4.
  • the branch is constructed from two conductor pieces 8 and 9, as shown in the exemplary embodiment, these conductor pieces are inserted one after the other, as can be seen from FIG. 3.
  • the end 11 of this conductor piece 9 is first bent so that the insertion of the second conductor piece 8 is easily possible, as can be seen in FIG. 3.
  • the conductor pieces are in longitudinal alignment of the core 2 in contact with it by means of the sections 12 and 13, while the ends 10 and 11, which are then at right angles, are adjacent to one another, as can be seen in FIG. 4.
  • the two ends 10 and 11 can be firmly connected to one another, for example by twisting, as shown in FIG. 5.
  • the electrical cable 1 is shown as it is bent back into its straight original position, one. branch 15 formed by twisting, consisting of the united ends 10 and 11 of the conductor pieces 8 and 9, is formed.
  • Fig. 1 shows the possibility of providing a plurality of corresponding branches 15 on a continuous cable 14.
  • the incision 5 can be made by grinding or by plunge or piercing using a suitable tool.
  • the conductor pieces 8 and 9 can be adapted to the problem to be solved in each case.
  • they have a rectangular cross section, their width defining the contact area with the conductive core and their thickness determining the strength of the insertion and the clamping between the sheath 4 and the core 2, on the one hand, and the possible current intensity of the current to be branched, on the other hand.
  • sections 12 and 13 have a length of the order of 30 mm, for example. 5, the two ends 10 and 11 are twisted together and cut to length. However, they can also be covered with a common cable lug to be crimped and can be electrically connected in this way.
  • the insulating sheath 4 clings closely to the circumference of the ends 10 and 11 of the conductor pieces which protrude from the sheath, the tightness can be improved even more if, for example, cable branches are to be used in damp locations by using a sealing compound in the area of the incision.
  • FIG. 6 Another possibility of forming a seal in the area of the connection between the cable 1 and the conductor pieces 8 and 9 is shown in FIG. 6.
  • the line piece 8 is insulated by a sheath 21 in its area which has not been used to form the connection.
  • a encapsulation 22 surrounds the entirety of the connection zone and ensures tightness both on the sheath 4 of the cable 1 and on the sheath 21 of the conductor piece 8.
  • FIG. 7 Another way of forming a seal is shown in FIG. 7.
  • the conductor piece 8 is insulated by a sheath 21 in the area which has not been used to form the connection.
  • the cable should have a certain flexibility for a good insertion of the sections of the conductor pieces between the sleeve and the core.
  • the cable can have a simple insulating sheath or a sheath made of a composite material. It can also be considered in certain applications to give sections 12 and 13 a cylindrical segment-shaped profile in order to achieve an optimal contact surface with the conductive core of the cable.
  • the branch according to the invention offers itself in a particularly simple manner for reinforcement by welding.
  • a method of working can be selected which includes direct heating through the Joule effect.
  • the twisted branch piece 15 After local preheating at the level of the branch, the twisted branch piece 15 is clamped as close as possible to the point of the branch between two graphite electrodes 17 and 18, which are connected to conductors 19 and 20 of a circuit through which heavy current flows. Local warming continues through heat conduction to soul 2.
  • the end of the wire 16 melts and the tin flows by gravity with infiltration between the two sections 12 and 13 of the conductor pieces and the core of the cable.
  • an insulating sleeve 4 for example made of an elastomer or a thermoplastic elastomer, which resists the local temperature increase.
  • the corresponding ends of the conductor pieces can also be tinned to prepare for welding.
  • the branch can also be formed from one or more than two conductor pieces.
  • the method according to the invention involves the use of multiple effects Lichungsformen allows that can be adapted to a particular degree to the connection problem to be solved in each case. This applies in particular to the choice of the profile of the incision made in the insulating sheath, the thickness of this sheath, the cross section of the conductor pieces, the length of the sections of the conductor pieces inserted between the core and the sheath, the type of connection of the protruding from the sheath and the branch forming parts of the conductor pieces and the fact and / or the type of welding of the inserted sections with the core of the cable.
