Definitions

  • the invention is in the field of flexible electrical lines, such as are used for the power supply of small electrical devices, and is applicable to the design of such lines with a view to better performance properties.
  • Small electrical devices in particular hand-held devices, such as shavers and toothbrushes, are connected to the power supply by means of multi-core flexible electrical lines, these lines being provided at least at one end with a plug for insertion into a socket.
  • the other end can have a socket for connecting the line to the small device (for example, common for shavers) or inserted directly into the small device (for example, common for toothbrushes).
  • Plugs and sockets are usually made up, that is molded on at the end of the cable.
  • the connector pins or the socket elements are fixed in a pin bridge
  • the connecting cables used for small electrical devices are either ' twin or triple cables with fine-stranded copper conductors or two- or three-core plastic or rubber hose lines.
  • the invention is based on the object of such a line Separation of the electrical function "power line” from the mechanical function "tensile strength" better adapted to the electrical and mechanical requirements.
  • each wire of at most 0.5 mm 2 in one or more gusset spaces stranded or parallel juxtaposed wires tensile threads are arranged on a plastic basis and that the ends of these threads are fixed to the pin bridge of the plug or the socket.
  • the electrical cross section is determined exclusively from an electrical point of view, so that a material saving and thus a reduction in the outer dimensions is achieved compared to conventional lines.
  • the mechanical function "tensile strength" is carried out by tensile threads which are arranged in the gusset spaces of the wires and thus do not lead to an increase in the external dimension of the line again.
  • the line therefore has small external dimensions and is particularly light.
  • the intended anchoring of the tension-resistant threads on the pin bridge also mechanically protects the mechanically particularly endangered line / plug or line / socket transition. In the course of the line, the necessary tensile strength is ensured by the frictional connection of the tensile threads with the wires and the plastic sheath.
  • FIGS. 1 to 5 Exemplary embodiments of the new line are shown in FIGS. 1 to 5.
  • 1 to 4 show cross-sectional images of different line types and
  • FIG. 5 shows a connector provided with a connector. Line end.
  • the lines shown in FIGS. 1 to 4 are two-wire or three-wire lines in a stranded and thus round version (FIGS. 1 and 2) or in a non-stranded and thus flat version (FIGS. 3 and 4). .
  • the lines can also be coiled.
  • Each line consists of the wires 1 and 2 or 3, the plastic sheath 6 or 7 or 8 or 9 and the tensile threads 1 ' 0 arranged in the gusset spaces of the wires on a plastic basis.
  • Each wire has a fine wire or fine-wire copper conductor 4 with a cross section of about 0.2 mm 2 and an extruded plastic insulation 5.
  • the tensile threads 10, which need not be arranged in all gusset spaces, are preferably those based on a polyamide, as are commercially available under the name "Kevlar”.
  • the housing 14 consists of an injection-molded plastic part and comprises the plug bridge including the cable end with the plastic jacket 6.
  • the inwardly projecting hook 15 Arranged between the two connector pins 12 and 13 on the pin bridge 11 is the inwardly projecting hook 15, on which the ends of the tension-resistant threads 10 are fixed.
  • This fixation can take place, for example, by knotting two threads in each case or also by knotting a single thread. But there is also the possibility of welding the ends of several threads together and placing the loop formed thereby over the hook 15. It is also conceivable to fix the tensile threads to the hook 15 by means of one or more cable lug-like sleeves.
  • the tension-resistant threads can also be fixed by squeezing in a metallic sleeve which is firmly connected to the pin bridge, or their ends can be glued to the pin bridge or clamped to the pin bridge. It is essential in any case that the threads are fixed (caught) independently of the fixing (contacting) of the conductors.
