Description

WIRE STRIPPER WITH ADJUSTABLE POSITIONING GUIDE TECHNICAL FIELD
[0001] The invention relates to a wire stripper with an adjustable positioning guide. Specifically, the invention relates to a wire stripper with an arrangement for aiding a user to position a wire to be stripped in a stripping position out of several adjacent stripping positions.
BACKGROUND
[0002] Tools for stripping wires are often provided with different stripping positions, each allocated to strip a wire of a specific thickness. Hence, one tool may be provided to strip wires of different thicknesses. The operator handling the tool will need to position the wire in the stripping position allocated to the specific wire. If the wire is not positioned in the allocated stripping position but in an adjacent position adapted to strip a wire of a different thickness the wire risk to be incorrectly stripped.
[0003] In many prior art solutions this may cause a problem, because due to spacesaving reasons the different stripping position are located close to each other, which makes it difficult to both spot which is the correct position for the wire and to actually locate the wire in said correct position.
[0004] Hence there is a need of a system or an arrangement that makes it easier for an operator to locate a wire in a correct position in a wire stripper comprising a plurality of adjacent wire stripping positions.
SUMMARY OF THE INVENTION
[0005] It is an object of the present invention to provide wire stripper by means of which a correct position and stripping of a wire is facilitated.
[0006] The invention relates to a wire stripper for stripping wires, the wire stripper comprising a first and a second counteracting die with opposed stripping surfaces whereof at least one stripping surface comprises adjacently positioned stripping positions, each stripping position being adapted for a specific wire width. An adjustable wire guide is arranged to guide a wire into a correct stripping position, the wire guide comprising a guide surface for guiding contact with a wire and a control means for manoeuvring the guide surface between different positions corresponding to the stripping positions.
[0007] In a specific embodiment the wire guide is arranged in connection to a first die wherein the guide surface has a substantially straight portion extending substantially orthogonally from said first die, the guide surface being arranged to be translated between different predetermined positions.
[0008] In another specific embodiment the wire guide comprises a lock function arranged to lock the guide surface in predetermined positions, so as to indicate correct positioning of the guide surface at a specific stripping position and to lock it in said stripping position. Specifically, the lock function may comprise a ball and a spring acting on the ball towards a recessed lower surface of the control means into which recesses the ball may be received in order to lock the control means in a desired position, corresponding to a specific stripping position.
[0009] In yet another specific embodiment the control means for manoeuvring the adjustable wire guide comprises a slide means for manoeuvring the guide surface between different stripping positions by sliding.
[0010] In another embodiment the control means for manoeuvring the adjustable wire guide comprises a control knob for manoeuvring the guide surface between different stripping positions by screwing.
[0011] The adjustable wire guide may further comprise an indicator for indicating a current position of the adjustable wire guide, and a magnifying glass may be arranged to follow the movement of the guide surface so that a current position of the guide surface may be viewed through the magnifying glass.
[0012] Further embodiments and advantages of the invention will be apparent from the following detailed description.

DETAILED DESCRIPTION OF EMBODIMENTS
[0014] In figures 1-4 a wire stripper 10 according to a first embodiment is shown. The wire stripper 10 is arranged for stripping wires. The wire stripper 10 comprises a first and a second counteracting die 11 and 12 with opposed stripping surfaces 17 and 23. At least one of the stripping surface comprises adjacently positioned stripping positions 18-22, see figure 5. Each stripping position is adapted for a specific wire width.
[0015] In accordance with the invention an adjustable wire guide 13 is arranged to guide a wire 30 into a correct stripping position. A correct stripping position is hence a position with a diameter that corresponds to the wire to be stripped. Typically, the wire stripper 10 is arranged to strip cables, i.e. to remove a plastic shield in order to expose underlying copper wires. Hence, the diameter of the individual stripping positions 18-22 are dimensioned to fit the copper wires, so as to only cut and remove the plastic shield and leave the copper wires uncut. The stripping in itself is well known to person skilled in the art is therefore 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 wire 30 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 straight portion 27 extending substantially orthogonally from the first die 11 . The guide surface 15 of the wire guide 13 is arranged to be translated between different positions. In the embodiment shown in figures 1-4 the control means 14 is comprised of a slide means for manoeuvring between different positions, corresponding to the different stripping positions 18-22, by sliding the guide surface 15.
[0018] In the shown embodiments the guide surface 15 is illustrated as surface of a substantially 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 opening could have a size allowing to entrance of a wire of a size corresponding to the largest stripping position. Further, such circular opening may be funnel-shaped so as to facilitate entrance of a wire. On the contrary, the guide surface 15 may also completely straight or have any shape there between as long as it provides a guiding support for the wire to be entered into a stripping position.
[0019] The wire stripper 10 further comprises an indicator for indicating a current position of the adjustable wire guide, wherein a magnifying glass 16 is arranged to follow the movement of the adjustable wire guide so that the current position may be viewed through the magnifying glass 16. The indicator may e.g. be a scale on which the characteristics of the stripping positions are listed. Typically, the diameter of each stripping position may be listed and the magnifying glass 16 so positioned that the characteristic of the stripping position at which 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 arranged to lock the guide surface 15 in predetermined positions corresponding to correct positioning of 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. In the present specification a lock function is intended to relate to a function that restricts movement in a clearly noticeable manner, i.e. to indicate to an operator that the guide surface 15 has been positioned in a predetermined position, preferably corresponding to specific stripping positions. Hence, in such a locked position it will take a slight, but clearly noticeable, greater effort to move the guide surface 15. In the shown embodiment the lock function comprises a ball 29 and a spring 31 acting on the ball. Further, the control means 14 includes a recessed lower surface into 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] In the embodiment shown in figures 5-7 the control means 24 for manoeuvring the adjustable wire guide comprises a control knob for manoeuvring the guide surface 15 between different stripping positions by screwing. As is shown in figure 6 the control knob may 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 a bearing, at its distal end 26 opposite the control knob. The guide surface 15 of the adjustable wire guide 13 has a threaded portion that mates with the thread(s) of the threaded pin 25.
[0022] In figure 5 the stripping positions 18-22 are clearly visible. The opposed stripping dies 11 and 12 comprises identical half circular cavities in the respective surface 17 and 23 of the dies 11 and 12. In another not shown embodiment only one of the dies 11 include cavities, whereas the opposed die may have a substantially straight surface. In figure 5 the guide surface 15 of the adjustable wire guide 13 is positioned so as to direct a wire to be stripped into the outermost stripping position 22, which in the shown embodiment is the largest cavity intended for a wire of the largest diameter. As is shown the guide surface 15 of the adjustable wire guide 13 includes a substantially straight portion 27 extending substantially orthogonally from the first die 11 , wherein said straight portion 27 forms an extension of the inner surface of the relevant stripping position, such that a wire that is inserted into the jaw of the wire stripper will be directed into said relevant stripping position by said straight portion.
[0023] Above, the invention has been described with reference to specific embodiments. 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 the following claims. For instance, the wire stripper 10 in the shown embodiments has opposed dies 11 and 12 that are arranged to meet each other in the axial direction of length axis of the wire stripper, wherein the guide surface 15 is arranged to be translated in the lateral direction perpendicular to the mutual movement of the dies. The invention also relates to wire strippers in which the dies are arranged to meet each other in a direction orthogonal to the length axis of the wire stripper, wherein the guide surface 15 of the adjustable wire guide 13 is arranged to be translated in the axial direction perpendicular to the mutual movement of the dies.
