DETAILED DESCRIPTION OF EI\/|BOD||\/IENTS
[0014] ln figures 1-4 a wire stripper 10 according to a first embodiment is shown. Thewire stripper 10 is arranged for stripping wires. The wire stripper 10 comprises a first and asecond counteracting die 11 and 12 with opposed stripping surfaces 17 and 23. At least oneof the stripping surface comprises adjacently positioned stripping positions 18-22, see figure5. Each stripping position is adapted for a specific wire width.
[0015] ln accordance with the invention an adjustable wire guide 13 is arranged toguide a wire 30 into a correct stripping position. A correct stripping position is hence aposition with a diameter that corresponds to the wire to be stripped. Typically, the wirestripper 10 is arranged to strip cables, i.e. to remove a plastic shield in order to exposeunderlying copper wires. Hence, the diameter of the individual stripping positions 18-22 aredimensioned to fit the copper wires, so as to only cut and remove the plastic shield and leavethe copper wires uncut. The stripping in itself is well known to person skilled in the art istherefore not described in detail in this application. This invention relates to correct positioning of a wire prior to and during a stripping operation.
[0016] The wire guide 13 comprises a guide surface 15 for guiding contact with a wire30 and a control means 14 for manoeuvring the guide surface between different positions,corresponding to the stripping position 18-22 of the counteracting dies 11 and 12.
[0017] The guide surface 15 in the shown embodiment has a substantially straightportion 27 extending substantially orthogonally from the first die 11. The guide surface 15 ofthe wire guide 13 is arranged to be translated between different positions. ln the embodimentshown in figures 1-4 the control means 14 is comprised of a slide means for manoeuvringbetween different positions, corresponding to the different stripping positions 18-22, bysliding the guide surface 15.
[0018] ln the shown embodiments the guide surface 15 is illustrated as surface of asubstantially parabolic shape. The guide surface 15 may however also be circular forming a circular opening through which a wire to be stripped could be entered. Such circular openingcould have a size allowing to entrance of a wire of a size corresponding to the largeststripping position. Further, such circular opening may be funnel-shaped so as to facilitateentrance of a wire. On the contrary, the guide surface 15 may also completely straight orhave any shape there between as long as it provides a guiding support for the wire to beentered into a stripping position.
[0019] The wire stripper 10 further comprises an indicator for indicating a currentposition of the adjustable wire guide, wherein a magnifying glass 16 is arranged to follow themovement of the adjustable wire guide so that the current position may be viewed throughthe magnifying glass 16. The indicator may e.g. be a scale on which the characteristics of thestripping positions are listed. Typically, the diameter of each stripping position may be listedand the magnifying glass 16 so positioned that the characteristic of the stripping position atwhich the guide surface 15 is positioned is visible through the magnifying glass 16.
[0020] As is apparent in figure 2 the wire guide 10 comprises a lock function arrangedto lock the guide surface 15 in predetermined positions corresponding to correct positioningof the guide surface 15 at a specific stripping position of the different stripping positions 18-22 and to lock the guide surface 15 in said stripping position. ln the present specification alock function is intended to relate to a function that restricts movement in a clearly noticeablemanner, i.e. to indicate to an operator that the guide surface 15 has been positioned in apredetermined position, preferably corresponding to specific stripping positions. Hence, insuch a locked position it will take a slight, but clearly noticeable, greater effort to move theguide surface 15. ln the shown embodiment the lock function comprises a ball 29 and aspring 31 acting on the ball. Further, the control means 14 includes a recessed lower surfaceinto which ball 29 may be received in order to lock the control means 14 in a desired position,corresponding to a specific stripping position 18-22.
[0021] ln the embodiment shown in figures 5-7 the control means 24 for manoeuvringthe adjustable wire guide comprises a control knob for manoeuvring the guide surface 15between different stripping positions by screwing. As is shown in figure 6 the control knobmay be arranged on a back portion of the wire stripper 10. Further, as is shown in figure 7,the control means 24 includes a threaded pin 25, which is mounted, e.g. journalled in abearing, at its distal end 26 opposite the control knob. The guide surface 15 of the adjustablewire guide 13 has a threaded portion that mates with the thread(s) of the threaded pin 25.
[0022] ln figure 5 the stripping positions 18-22 are clearly visible. The opposedstripping dies 11 and 12 comprises identical half circular cavities in the respective surface 17 and 23 of the dies 11 and 12. ln another not shown embodiment only one of the dies 11include cavities, whereas the opposed die may have a substantially straight surface. ln figure5 the guide surface 15 of the adjustable wire guide 13 is positioned so as to direct a wire tobe stripped into the outermost stripping position 22, which in the shown embodiment is thelargest cavity intended for a wire of the largest diameter. As is shown the guide surface 15 ofthe adjustable wire guide 13 includes a substantially straight portion 27 extendingsubstantially orthogonally from the first die 11, wherein said straight portion 27 forms anextension of the inner surface of the relevant stripping position, such that a wire that isinserted into the jaw of the wire stripper will be directed into said relevant stripping positionby said straight portion.
[0023] Above, the invention has been described with reference to specificembodiments. The invention is however not limited to these embodiments. On the contrary,the invention includes other embodiments within its scope which is limited only by thefollowing claims. For instance, the wire stripper 10 in the shown embodiments has opposeddies 11 and 12 that are arranged to meet each other in the axial direction of length axis of thewire stripper, wherein the guide surface 15 is arranged to be translated in the lateral directionperpendicular to the mutual movement of the dies. The invention also relates to wirestrippers in which the dies are arranged to meet each other in a direction orthogonal to thelength axis of the wire stripper, wherein the guide surface 15 of the adjustable wire guide 13is arranged to be translated in the axial direction perpendicular to the mutual movement ofthe dies.
