Definitions

  • the invention relates to a method for forming a plug on one end of a cable, which plug comprises a connecting piece, a casing of plastic material and a colour code, whereby the connecting piece is attached to the end of the cable, after which part of the connecting piece and part of the cable comprising said end are enveloped by the plastic casing.
  • the invention also relates to plugs comprising a connecting piece, a casing of plastic material and possibly a colour code.
  • the connecting piece which for example comprises electrically conducting pins, is attached to the end of a cable comprising electrically conducting wires. Then the casing is formed on the end of the cable by means of a plastic injection moulding technique, whereby a portion of the connecting piece projects from the casing.
  • the plug is provided with a colour code, which for example corresponds with a colour code present on the appliance.
  • Such a colour code is made up of an annular tape of a selected colour different from the colour of the casing, which is provided round the casing.
  • One drawback of such a tape is that the tape will come loose with the lapse of time, and that affixing the tape is a relatively labourious activity. Furthermore the tape affects the appearance of the plug.
  • the object of the invention is to provide a method for forming a plug, wherein the plug is provided with a colour code in a simple manner.
  • the plastic casing is made of at least two interconnected, differently coloured parts of plastic material, whereby the first part, which comprises a cylindrical portion, is first attached to the end of the cable, after which the end of the cable provided with said first part is placed into a mould, whereby said cylindrical portion abuts at least partially against the mould near its centre, whilst said cylindrical portion is clear of the mould on either side of said centre, after which a second plastic part is formed in the mould, which plastic part abuts against said first part on either side of said centre of said cylindrical portion.
  • Said first and said second part have different colours, whereby the second part has the same colour as the cable, for example, and the colour of the first part forms the colour code.
  • the first part comprises a cylindrical portion, of which only a small part located near the centre will be visible after the second part has been formed, the accuracy with which first part is to be positioned in the mould is not very critical. As a result of this the placing of the first part in the mould can take place relatively quickly. Furthermore this makes it possible to compensate for dimensional tolerances of the connecting piece relative to the first part. Said dimensional tolerances result from the shrinking of the plastic material, for example.
  • the second part can thus be accurately positioned relative to the connecting piece, whereby the fact that the first part is not accurately positioned relative to the connecting piece does not constitute a problem.
  • One embodiment of the method according to the invention is characterized in that said first part is provided with teeth.
  • Said teeth ensure a proper fixation of the second part to the first part.
  • the invention also relates to a plug comprising a connecting piece, a casing of plastic material and a colour code, which plug is characterized in that said casing comprises at least two interconnected, differently coloured parts of plastic material, whereby the first part comprises a cylindrical portion, which is connected to the second part on either side of its centre, seen in axial direction, leaving clear a portion located near the centre.
  • the colour of the first part thereby forms the colour code of the plug. Said colour code cannot be removed from the plug, this in contrast to the above-described known plug.
  • the entire plug has a characteristic colour, for example white or red.
  • a characteristic colour for example white or red.
  • the portion of the first part that is exposed to view may be provided on the plug on a relatively subtle manner.
  • Figures 1A-1E show various steps of the forming of a plug on one end of a cable in accordance with the invention.
  • Figure 1A shows a cable 1, which comprises two electrically insulated wires 2, 3, which have been stripped of their electric insulation near their ends.
  • a connecting piece 4 is disposed near the end of cable 1, which connecting piece for example comprises an electrically conducting sleeve 5 and an electrically conducting pin 6 concentrically positioned therein.
  • the ends of wires 2, 3 are connected to pin 6 and sleeve 5 respectively by means of a soldering technique, for example.
  • first part 7 of plastic material is fixed round a portion of connecting piece 4 and one end of cable 1.
  • First part 7 comprises a cylindrical portion 8, which extends parallel to the central axes of cable 1 and connecting piece 4. Teeth 9 are provided near one end of first part 7.
  • First part 7 is formed by means of a plastic injection moulding technique, using mould 10 of Figure 2.
  • Mould 10 comprises two identical mould halves 11, 12, which are capable of movement relative to each other.
  • Each mould half 11, 12 is provided with a gate 13, via which plastic material is injected into mould 10.
  • cable 1A and the connecting piece 4 attached thereto are placed into mould 10, cable 1 will abut against a corresponding edge 14 of mould 10, whilst sleeve 5 of connecting piece 4 will abut against an edge 15 of mould 10, which forms a stop member.
  • First part 7 is injection-moulded from a plastic having a selected characteristic colour, for example red, white or yellow.
  • the portion of the plug to be formed that forms a colour code is present on cylindrical portion 8, which has a width B which is larger than the colour code that will eventually be visible.
  • Figure 1C is a view of the cross-section shown in Figure 1B of a cable and a plug to be formed thereon.
  • Mould 20 comprises two identical mould halves 21, 22, which are capable of movement relative to each other, which mould halves are each provided with gates 23.
  • the mould is formed with a profile, which corresponds with the eventual desired profile on the plug to be formed.
  • Said profile 24 comprises three annular flanges 25, 26, 27, which are separated from each other by two annular recesses 28, 29.
  • Annular flange 26 extends further towards the central axis of mould 20 than adjacent flanges 25, 27.
  • Flange 26 extends in the direction of the central axis, so far that when a cable comprising a first part 7 already formed thereon is present in mould 20, flange 26 abuts against cylindrical portion 8 of first part 7.
  • the width b of flange 26 is thereby smaller than width B of cylindrical portion 8 of first part 7.
  • a front edge 30 of sleeve 5 will be aligned to extend parallel to an edge 31 of mould 20.
  • Mould 20 abuts against sleeve 5 and cable 1 with edges 32 and 33 respectively.
  • plastic material is injected into mould 20 via gates 23, thus forming second part 34 on cable 1.
  • Second part 34 comprises an annular recess 35 defined by flange 26, which has a width b through which part of cylindrical portion 8 of first part 7 is visible.
  • Second part 34 is provided with annular flanges 36 on either side of annular recess 35.
  • Annular recesses 37 defined by flanges 27 of mould 20 are formed on sides of flanges 36 that face away from each other.
  • annular recess 35 would be located in the centre of cylindrical part 8. If, however, the distance from edge 30 of sleeve 5 to cylindrical portion 8 differs from the distance to be theoretically expected, due to dimensional tolerances, or if edge 30 cannot be accurately aligned with respect to edge 31 of mould 20, recess 35 will be offset from the centre of cylindrical portion 8 in the direction indicated by arrow P or in the opposite direction. Since width b of recess 35 is smaller than width B of cylindrical portion 8, this will not be visible on the outside of second part 34. From the outside of the plug 38 formed on cable 1 the part of cylindrical portion 8 that is visible through recess 35 will remain positioned symmetrically relative to annular recesses 37.
  • Teeth 9 provide a firm fixation of second part 34 to first part 7.
  • Arrow 39 may point in the direction indicated by arrow P, or in the opposite direction, with arrow 39 indicating the direction of the signal to be passed through cable 1. This is especially important with cables through which a signal can or must be passed in one direction only.
  • the flexible part 40 providing pull relief comprises a number of flanges 41, which are separated from each other by slots 42.
  • Flange 43 located furthest away from connecting piece 4 is thicker, so that a solid connection with cable 1 is formed.
  • Figure 4 shows cable 1 and the plug 38 formed thereon in a position wherein central axis 44 of cable 1 is in line with central axis 45 of plug 38.
