Description

field of technology

[0001] The invention relates to a stripping tool for removing an outer sheath and / or a conductor insulation of an electrical single- or multi-core cable, wherein the stripping tool has hollow body partial shells connected to each other by means of a common pivot axis, which can be pivoted towards each other to form a hollow body that at least partially accommodates a cable, wherein the hollow body partial shells have at least one cutting element. State of the art

[0002] Wire stripping tools of the aforementioned type are known in the prior art. For example, publication WO 2005 / 025023 A1 discloses a wire stripping tool that can be used both for removing the outer sheath of a multi-core cable and for stripping the insulation of a single conductor. The wire stripping tool consists of two pivotable half-shells connected at a shell edge, which have several cutting elements transverse to the longitudinal direction of the half-shells. To remove the outer sheath or the conductor insulation, the cable is inserted end-to-end through an opening into a cutting element. The wire stripping tool is gripped circumferentially, with the user's hand encompassing almost the entire tool and the thumb and forefinger pressing together gripping surfaces located at the end face.

[0003] DE 20 2014 106 142 U1 discloses a stripping tool for removing the insulation of single- or multi-core cables by means of two jaws which are connected to each other via a common hinge axis to form a hollow body which can be opened to receive the cable to be stripped and on one end face of which are provided with cutting edges for a circular cut of the insulation near the end of the cable.

[0004] DE 20 2009 000 142 U1 discloses a hand tool comprising a lower cover, on the side edge of which a rotary connection is provided and on the front side edge of which a first recess is formed, and an upper cover, which is arranged over the lower cover and on the side edge of which a second recess corresponding to the first recess is formed.

[0005] For example, to remove an outer sheath from multi-core cables hanging in an electrical box, it is necessary for the user to twist their forearm and / or hand in order to exert maximum force. Summary of the invention

[0006] Based on the aforementioned state of the art, the object of the invention is to create a wire stripping tool which is further developed with regard to comfort and power transmission.

[0007] To solve this, the invention proposes that the stripping tool has at least two hollow body sections arranged at an angle between 90° and 170°, in particular between 110° and 150°, wherein at least a first hollow body section has two hollow body shells pivotably movable relative to each other, of which at least one hollow body shell can be pivoted without displacing a second hollow body section, wherein a cutting element is arranged in the hollow body at the first hollow body section, wherein the hollow body has a first, end-face opening in the area of ​​the cutting element through which a cable to be stripped can be guided.

[0008] According to the invention, a first hollow body section and a second hollow body section are arranged at an obtuse angle between 90° and 170° to each other, resulting in an angled shape of the wire stripping tool. This angled shape allows for ergonomic use by the user, enabling at least the same tensile force to be applied to a cable without placing increased strain on the user's forearm and / or hand. At least one of the first hollow body sections has a cutting element for removing the sheath or conductor insulation, while a second section serves as a handle for guiding the wire stripping tool. The two hollow body sections advantageously form a pistol-like shape for the wire stripping tool. This pistol-like shape corresponds to the natural position of the wrist when applying a tensile force.This prevents excessive strain on the wrist.

[0009] Basically, at least two different embodiments of the wire stripping tool exist. According to a first conceivable embodiment, only one hollow body section has two hollow body shells that can be pivoted relative to each other about a pivot axis, while the second hollow body section is a fixed handle and therefore has no pivotable hollow body shells. According to a conceivable second embodiment of the invention, both hollow body sections have hollow body shells that can be pivoted relative to each other; that is, each hollow body section has a pivot axis. According to this second embodiment, each hollow body section can be used both for wire stripping and as a handle.

[0010] It is particularly recommended that two hollow body sections each have two pivotally movable hollow body shells, wherein in one possible embodiment a first hollow body section is designed to accommodate a cable with a first diameter, and a second hollow body section is designed to accommodate a cable with a second diameter that differs from the first. This optimizes the stripping tool for stripping at least two cables of different diameters. For example, a cable with a larger diameter, such as a multi-core round and moisture-resistant cable (e.g., NYM cable) with a diameter of 8 mm to 13 mm, can be stripped in the first hollow body section, while a coaxial cable and / or data cable with a diameter of 4.5 mm to 10 mm can be stripped in the second hollow body section.In addition, it is also possible, alternatively or additionally, to optimize one of the hollow body sections specifically for a flat or round cable or cables with different sheath thicknesses.

[0011] Furthermore, it is proposed that the stripping tool have at least two pivot axes, one located on a common first hollow body shell and the other on separate second hollow body shells. The stripping tool thus has an angled first hollow body shell supporting two or more pivot axes arranged at an angle to each other corresponding to the angle between the hollow body sections. A separate second hollow body shell is arranged on each of these pivot axes, allowing it to pivot independently of the movement of the other second hollow body shells. Therefore, when inserting a cable into the hollow body, it is not necessary to open the entire hollow body, but only one of the hollow body sections, formed by the first hollow body shell and only one of the separate second hollow body shells.The remaining hollow sections of the tool remain closed, allowing them to be held as a handle, for example, without having to release them to insert the cable into the stripping tool. This simplifies the use of the stripping tool and saves time during application.

[0012] The first and second pivot axes, arranged on separate second hollow body shells, can be located either on the same shell edge of the hollow body or the first hollow body shell, on opposite shell edges, or offset by an angle between 0° and 180° (circumferentially). An arrangement offset by 180° circumferentially, i.e., oppositely, ensures that the hollow body, whenever the user grips one of the hollow body shells, always guides the cable between the hollow body shells from the left side. In other words, this means that when grasping the first hollow body shell and when grasping the second hollow body shell, the user, following the pistol-like shape of the stripping tool (e.g., with their right hand), always looks at the stripping tool from the left.

[0013] The hollow body sections of a hollow body area of ​​the wire stripping tool can, preferably, be locked in a closed position. This can apply to both hollow body sections, or alternatively, preferably, only to one of the two hollow body sections. The locking mechanism further simplifies the handling of the wire stripping tool. The locking mechanism can affect the hollow body area used for stripping or sheathing removal. The locking mechanism can also prove advantageous in the area of ​​the hollow body section that can be used as a handle.

[0014] Preferably, the wire stripping tool can be used in both a locked and an unlocked position.

[0015] The hollow body sub-shells can be pivoted by means of an axle extending longitudinally along the hollow body sub-shell. This axle can be separate from the interacting hollow body sub-shells, for example, a inserted metal axle. Preferably, both second hollow body sub-shells are pivotably connected to the first, angled hollow body sub-shell via such an axle.

[0016] In one possible embodiment, the axle body can extend through a locking element. Such a locking element can serve to securely fasten a second hollow body shell. Furthermore, the axle body extending through the locking element can serve to preferably permanently fix the locking element to one of the hollow body shells, as well as to guide the locking element when it moves from a locked position to an unlocked position and vice versa.

[0017] Furthermore, and preferably, the locking element can be moved transversely to the longitudinal direction of the axle body into a locked and unlocked position. This also results in convenient handling, e.g., thumb-operated operation of the locking element to move it from one end position to the other. The direction of movement of the locking element can be, at least approximately, tangential in cross-section with respect to one of the hollow body shells.

[0018] In a preferred embodiment, at least the locking position is latched. In a further, also preferred, embodiment, such a latching occurs in both the locking and unlocking positions, and this latching can occur on the same hollow body shell. In one possible embodiment, this is the first hollow body shell. Preferably, the latching is such that it can be released solely by the user applying a sliding force to the locking element, for example, by overriding a provided detent projection.

[0019] It is further proposed that a first hollow body section has gripping tabs projecting beyond a circumferential surface for compressing the hollow body shells forming the hollow body using the thumb and index finger of a hand, and that a second hollow body section has a gripping surface for the simultaneous application of the palm of the hand. According to this embodiment, the gripping tabs of the first hollow body section are grasped and compressed during cable stripping, while the second hollow body section is guided essentially by the palm of the hand. It can be provided that both the first and second hollow body sections have gripping tabs, so that both hollow body sections can be used equally for stripping.It is recommended that the two gripping tabs be positioned perpendicular to the plane defined by the two hollow body sections. This corresponds to a natural hand position of a user when stripping a cable.

[0020] The invention further proposes a wire stripping tool with one or more of the aforementioned features, which comprises hollow body shells connected to one another by means of a common pivot axis. These shells can be pivoted towards each other to form a hollow body that at least partially accommodates a cable. The hollow body shells each have at least one cutting element, and the hollow body formed by the two hollow body shells has a cone in its outer contour, at least with respect to one end region, which widens towards a gripping surface of the wire stripping tool. The wire stripping tool thus has a conical outer contour at one or both end regions, which facilitates better accessibility of the stripping tool in narrow cable junction boxes, electrical boxes, or the like. This is particularly advantageous where several cables lie close together.To strip one of several closely spaced cables, the cable to be stripped is spread apart from the other cables, creating an angle between them. The conical end of the stripping tool is then inserted into this angle as deeply as possible until the conical surface is positioned as close as possible to the apex. The cutting element, located inside the hollow body, can advantageously be positioned within this conical end.

[0021] It is further proposed that a circumferential surface of the cone form an angle of approximately 30° to 60° with an end face of the end region. This corresponds to the typical spreading of a cable being stripped from several adjacent cables. The stripping tool can thus be used optimally.

[0022] Furthermore, it is proposed that the cone extend from an end face of the end region over a length of 5 mm to 20 mm. This provides a sufficiently large outer surface area of ​​the stripping tool for spreading a cable, while simultaneously maintaining the smallest possible diameter of the stripping tool – in order to ensure a handy tool.

[0023] Furthermore, the invention preferably proposes a wire stripping tool with one or more of the features described above, which has hollow body shells connected to one another by means of a common pivot axis and which can be pivoted towards each other to form a hollow body that at least partially accommodates a cable. The hollow body shells have at least one cutting element, and the hollow body has a recess at one edge of a shell, at which the hollow body shells can be pivoted towards each other, for pressing a cable into the hollow body. This recess has, in particular, an opening angle of less than 180°. This design makes it possible to press the wire stripping tool with a cable, so that it is not necessary to use a hand to pivot a hollow body shell.A cable to be inserted into the hollow body is pressed against the angled surfaces of the indentation, causing the two hollow body sections to separate and allowing the cable to be inserted. It is recommended that the indentation have an opening angle of less than 180° so that it does not form a flat surface, but rather that the edges of the indentation (similar to an overhang) extend over the inserted cable. This creates a point of contact against which the cable can grip and open the wire stripper. The user can then hold the wire stripper as usual by a gripping surface on, for example, the second hollow body section in one hand, and with a second hand press a cable against the indentation formed on the first hollow body section.Advantageously, the indentation is located near an end of the wire stripper, particularly an end that has an opening for inserting a cable. This makes it possible to advantageously position the indentation in an area accessible from essentially different directions. It is especially advantageous for the indentation to be located in an area whose outer contour has a cone that widens towards a gripping surface of the wire stripper. The wire stripper can thus be opened particularly easily by pressing a cable against the indentation. Alternatively, the indentation can also be formed on protruding grip tabs.

[0024] Furthermore, it is proposed that the opening angle of the indentation correspond to an opening width of 1 mm to 20 mm, in particular to the diameter of a cable to be inserted into the hollow body. The indentation is thus large enough to allow even a multi-core cable, such as an NYM cable, to engage an edge of the indentation in order to open the stripping tool. It is particularly recommended that the circumferential section of the indentation correspond approximately to the diameter of the cable to be inserted into the hollow body, so that slippage of the cable from the stripping tool is reliably prevented. An opening angle of 150° or less is particularly advantageous for the indentation.

[0025] It is recommended that a spring be assigned to the pivot axis, the restoring force of which allows the hollow body sections to pivot towards each other to form a hollow body or to pivot away from each other to open the hollow body. According to the first alternative, opening the wire stripping tool, i.e., inserting a cable between the hollow body sections, requires pivoting at least one hollow body section against the spring's restoring force. The spring's restoring force should be such that it is easily possible to open the hollow body section by means of a cable engaging the indentation. As soon as one of the hollow body sections is pivoted and the cable is positioned between the two hollow body sections, the restoring force pivots the hollow body section back into the closed position.In this method, the cable is securely held between the hollow body sections without any further action from the user. To strip or remove the cable, the user simply needs to squeeze the two hollow body sections together using the grip tabs conveniently located on the corresponding area of ​​the hollow body. In the second alternative, the hollow body sections can be pivoted apart by the spring's restoring force, meaning the restoring force acts in the direction of the pivoted position of the hollow body. To press the hollow body sections together, the user must overcome the spring's restoring force. As soon as the user releases their grip from the hollow body sections, the hollow body opens automatically due to the spring's restoring force, allowing the user to remove the cable from the tool without manually pivoting either of the hollow body sections.In this context, it may also be provided, for example, that a stripping tool has a first hollow body section with a spring whose restoring force is directed in a closing direction of the hollow body, wherein a second hollow body section has a spring whose restoring force is directed in an opening direction of the hollow body.

[0026] Furthermore, the invention preferably proposes a stripping tool according to one or more of the aforementioned features, which has hollow body shells connected to one another by means of a common pivot axis, which can be pivoted towards each other to form a hollow body that at least partially accommodates a cable, wherein the hollow body shells have at least one cutting element, wherein the hollow body shells have cutting elements arranged side by side in the direction of a shell edge at which the hollow body shells can be pivoted towards each other, wherein a guide track is assigned to the cutting elements, which has at least one web formed laterally to a cutting element for aligning a cable on a cutting element, wherein in the case of several webs these are arranged in the direction of the shell edge on opposite sides of two cutting elements,in particular, two adjacent cutting elements are formed. According to this embodiment, the stripping tool is advantageously designed to remove both the outer sheath of a multi-core cable and the insulation of a single-core cable. While removing an outer sheath is advantageously carried out, for example, via an end face of the stripping tool, removing insulation can be carried out, for example, in a direction perpendicular to it, i.e., at an edge of the hollow body shell. According to a conceivable embodiment, the cutting elements are arranged at the edge of the shell essentially opposite the pivot axis, at which the hollow body shell sections can be joined. Each hollow body shell section carries a cutting element.which corresponds to a cutting element of the opposite hollow body shell. In the open state of the stripping tool, the two hollow body shells are pivoted away from each other, so that the opposing cutting elements are separated and a cable can be placed between a pair of cutting elements. In the prior art, adjacent cutting elements are usually arranged directly next to each other in a direction parallel to the pivot axis, and these can, for example, be arranged next to each other in ascending order of size. The ascending size of the cutting elements corresponds to different cable diameters. The size difference between the cutting elements is often not easy to recognize, so that a user cannot immediately see, for example, ten, cutting elements arranged next to each other,which cutting element is most suitable, or which cutting element was used in a previous stripping process. According to one embodiment, the cutting elements are now assigned a guide track, which serves on the one hand to align a cable with a cutting element, and on the other hand to orient a user within the multitude of adjacent cutting elements. In a particularly simple embodiment, the guide track can have only one rib, which, for example, divides a series of cutting elements into two halves and thus provides assistance in identifying or recognizing the appropriate cutting element. If, for example, four cutting elements are arranged next to each other at the edge of the shell, the rib of the guide track can be positioned centrally between the second and third cutting elements.so that the user can easily and quickly identify all four cutting elements both tactilely and visually. If a larger number of cutting elements are arranged along the shell edge, it is recommended that the guide rail have several ribs, which are then formed longitudinally on opposite sides of two cutting elements, particularly on opposite sides of two adjacent cutting elements. It is especially advantageous to arrange two cutting elements between two successive ribs of the guide rail along the shell edge, allowing the user to orient themselves by the ribs when selecting a suitable cutting element. In this way, two or even three cutting elements can be arranged between successive ribs of the guide rail, so that the user first orients themselves by the ribs.For example, the user selects a section between the first and second ribs and then, relative to the section between the two ribs, places the cable against the left rib and lowers it onto the cutting element. This process can then be repeated multiple times without the need to recount cutting elements or similar actions each time. It is also advantageous if the cutting elements are arranged at different distances from each other, for example, grouped in pairs and spaced relative to an adjacent pair. This makes using the wire stripper particularly convenient. The guide is advantageously located on only one of the two hollow body halves.The webs of the first hollow body shell extend towards the second hollow body shell and protrude beyond the cutting elements. When the stripping tool is closed, the webs can rest against the outer circumferential surface of the opposite hollow body shell. The guide not only provides orientation but also aligns the cable relative to the cutting elements. Furthermore, the cable is centered on a cutting element when the stripping tool is folded and the two cutting elements of a pair meet.

[0027] Furthermore, the guide profile can be provided with two partial guide profiles arranged on opposite sides of the cutting elements, perpendicular to the edge of the shell. The cutting elements, which are arranged along the edge of the stripping tool, are thus flanked on both sides—that is, both radially outward and radially inward—by a partial guide profile of the guide profile, with the partial guide profiles advantageously arranged parallel to the edge of the shell. The guide profile thus forms a three-dimensional guide for the cable to be stripped. Since the cable is guided both in front of and behind the respective cutting element when inserted into the stripping tool, tilting of the cable relative to the cutting element is prevented. This ensures optimal stripping results.

[0028] Furthermore, a wire stripping tool is proposed according to one or more of the aforementioned features, which has hollow body shells connected to each other by means of a common pivot axis, which can be pivoted towards each other to form a hollow body that at least partially accommodates a cable, wherein the hollow body shells have at least one cutting element, wherein the hollow body shells have cutting elements arranged side by side in the direction of the shell edge at a shell edge at which the hollow body shells can be connected, wherein at least one hollow body shell has a marking formed behind a cutting element in the insertion direction of a cable, which enables a user to measure an insertion length to be stripped analogously.Advantageously, the marking features multiple lines arranged parallel to the cutting elements, each of which is also conveniently labelled with a millimeter value, for example "4", "8", "12", "16". When inserting a cable to be stripped into the stripping tool, the user can immediately see how far the cable extends into the tool.

[0029] Naturally, it is also possible to provide a corresponding marking for stripping a multi-core cable. This marking is then arranged perpendicular to the marking of the cutting elements, essentially in a direction parallel to the pivot axis of the stripping tool.

[0030] It is also possible for the marking to be three-dimensionally shaped. For example, this shape could be a ridge that protrudes from the inner wall of the relevant hollow body shell. This makes it easier for a user of the stripping tool to measure the corresponding length.

[0031] Furthermore, a stripping tool, in particular a stripping tool according to one or more of the aforementioned features, is proposed, in which a first hollow body part area can have functional tabs projecting beyond a circumferential surface, wherein at least one functional tab has a cutting element with a cutting edge extending in the direction of the pivot axis.

[0032] The at least one functional tab can, preferably, project beyond the circumferential surface of the hollow body part shell, to which the functional tab is preferably integrally and uniformly molded, such that the functional tab achieves an approximately radial orientation in a corresponding cross-section with respect to a central axis extending longitudinally through the relevant hollow body part area. In a preferred embodiment, the functional tab provides a cutting element, e.g., for cutting a cable sheath along its longitudinal extent.

[0033] The use of a cutting edge arranged in a functional tab is preferably carried out outside the area encompassed by the hollow body partial shells, and furthermore in a peripheral area.

[0034] Preferably, two functional tabs are provided, each assigned to the interacting hollow body shells. Furthermore, the functional tabs can overlap each other, at least in the cutting edge area, when the hollow body shells are closed. Both functional tabs can have a cutting edge pointing towards the other functional tab, or alternatively, only one of the two functional tabs can have a cutting edge. In the latter case, the functional tab without a cutting edge can provide a support area for the cable being cut into on the sheath side.

[0035] The functional tabs, which can be brought into overlap at least in the area of ​​the cutting edge, leave a through-opening in the operating position, which preferably corresponds to the shell's closed position. This through-opening has a diameter corresponding to the usual diameters of electrical cables to be processed. The through-opening is preferably circular in cross-section, or optionally elliptical. The cutting edge dips radially inwards into the cross-sectional area of ​​the opening to engage the sheathing of the cable being processed.

[0036] Preferably extending axially from the through-flow opening, a guide for the cable, which also passes through the through-flow opening, can be formed on the housing, e.g. in the form of a system groove.

[0037] A particularly user-friendly design is one in which the functional tabs are configured as attack tabs, especially those already described. Accordingly, pressure towards a closed position can be applied via the attack tabs during the stripping process, thus exerting further pressure on the cutting edge as it enters the sheathing.

Description of the embodiments

[0039] The Fig. Figures 1 to 6 show a first side of an exemplary stripping tool 1 for removing an outer sheath 2 and / or a conductor insulation 3 of a single- or multi-core electrical cable 4. The stripping tool 1 has two hollow body sections 12, 13 forming a hollow body 9, which are angled at an angle α (see Figure 1). Fig. 2) are arranged relative to each other. The angle α here is approximately 135°. The two hollow body sections 12, 13 have a common first hollow body section shell 7, on which two pivot axes 5, 6 are arranged. A first pivot axis 5 is assigned to the first hollow body section 12, while a second pivot axis 6 is assigned to the second hollow body section 13. A second hollow body section shell 8 is arranged on each of the pivot axes 5, 6, which can be pivoted about the respective pivot axis 5, 6 relative to the first hollow body section shell 7. The pivot axes 5, 6 are arranged on opposite shell edges 19 of the first hollow body section shell 7.

[0040] In the hollow body 9, a cutting element 10 is located both on the first hollow body section 12 and on the second hollow body section 13 (see Fig. 4), in particular a pair of cutting elements, arranged, the cutting edge 11 of which runs perpendicular to the pivot axes 5, 6. This cutting element 10 serves in particular for removing an outer sheath 2 of a multi-core cable 4. In the area of ​​this cutting element 10, the hollow body 9 has an opening 16 through which a cable 4 to be stripped can be guided.

[0041] The end region 17 of the hollow body section 12, which carries the opening 16, also has a cone 18 in its outer contour that widens in a direction away from the opening 16. The cone 18 has an angle β of approximately 45° relative to the plane of the opening 16 (see Fig. 2).

[0042] Overall, the first hollow body section 12 and the second hollow body section 13 of the stripping tool 1 form a pistol-like shape, so that a user of the stripping tool 1 uses a grip surface 15 of the hollow body sections 12, 13 as a handle and the other hollow body section 13, 12 as the actual tool for stripping a cable 4.

[0043] The stripping tool 1 has a plurality of cutting elements 21, in particular pairs of cutting elements, here six cutting elements 21, on a shell edge 19. These are arranged such that corresponding cutting elements 21 of a pair are located on the first hollow body shell 7 and the second hollow body shell 8. A guide track 22 is formed in the direction of the cutting elements 21 arranged side by side on the shell edge 19, which has several webs 23 for guiding a cable 4 into the hollow body 9 (see Fig. 5 and Fig. 6) The webs 23 are divided onto two partial guide guides 24 of the guide guide 22, the partial guide guides 24 extending parallel to and on opposite sides of the shell edge 19 having the cutting elements 21.

[0044] Fig. Figure 4 shows the wire stripping tool 1 in an open state, with the two second hollow body shells 8 pivoted about the pivot axes 5 and 6. A marking 25 is visible on the first hollow body shell 7, indicating the distance from a cutting element 21 to a line of the marking 25. This allows the length to be stripped from a cable 4 to be measured. The individual lines of the marking 25 are labeled with millimeter values, here "8", "12", and "16".

[0045] Finally, engagement lugs 14 are formed on the hollow body shells 7, 8, which serve to compress the two hollow body shells 7, 8 during the stripping process. The engagement lugs 14 extend from the circumferential surface of the hollow body 9 in a direction that is perpendicular to a plane spanned by the hollow body shell sections 12, 13.

[0046] Fig. Figure 5 shows the stripping tool 1 with two cables 4 inserted into the hollow body 9. The cables 4 have different diameters, with the cable 4 inserted into the first hollow body section 12 having a larger diameter than the cable 4 inserted into the second hollow body section 13. However, during the stripping process, usually only one cable is located in either the first hollow body section 12 or the second hollow body section 13. Each hollow body section 12, 13 is optimized for specific cable 4 diameters. For example, the first hollow body section 12 may be designed for round and moisture-resistant cables with a diameter of 8 mm to 13 mm, while the second hollow body section 13 is optimized for data cables with a diameter of 4 mm to 8 mm.Depending on the respective diameter, the cutting element 10, the opening 16 or the inner diameter of the hollow body part areas 12, 13 can be designed.

[0047] The Fig. Figures 7 to 9 show a reverse side of the (in the Fig. (1-6 shown) a stripping tool 1, which has a recess 20 on the circumferential surface of the second hollow body section 13, which leaves out a circumferential section. The recess 20 cuts out an angled section of approximately 130° from the circumference of the hollow body section 13. A cable 4, which is to be inserted into the hollow body 9, can be placed into this recess 20 and pressed transversely against the shell edge 19 until the hollow body shells 7, 8 pivot away from each other. In doing so, the restoring force of a spring (not shown), which is arranged on the pivot axis 6 and seeks to close the hollow body 9, must be overcome.

[0048] Fig. Figure 7 shows the state in which a cable 4 lies in the indentation 20 and presses against the hollow body shells 7, 8. The cable 4 is supported against the inclined sides of the indentation 20. Fig. In step 8, the cable 4 is already guided between the two hollow body shells 7 and 8. Due to its restoring force, the spring closes the hollow body 9 immediately after the cable 4 has overcome the open shell edge 19.

[0049] Fig. Figure 9 shows a cross-section through the second hollow body section 13 in the area of ​​the indentation 20. The indentation 20 with an opening angle γ of approximately 130° can be seen as being cut out from the otherwise circular circumference of the hollow body section 13.

[0050] The invention works, for example, as follows: To strip the outer sheath 2 from a cable 4, a user selects a hollow body section 12, 13 of the stripping tool 1 that best corresponds to the diameter of the cable 4. If, for example, the cable 4 has a diameter of 6 mm, the second hollow body section 13 is particularly suitable. The user therefore grasps the stripping tool 1 at the first hollow body section 12, which is connected to the second hollow body section 13 in a pistol-grip style. The gripping surface 15 of the first hollow body section 12 serves as a support for the user's hand, in particular the palm and the ring and middle fingers. With the other hand, the user grasps the cable 4 to be stripped and presses it within the indentation 20 against the hollow body shells 7, 8 of the second hollow body section 13 (see figure). Fig. 7 and Fig. 9) If the user applies a force greater than the restoring force of the spring associated with the pivot axis 6, the second hollow body section 8 pivots, allowing the cable 4 to be inserted into the hollow body 9. If necessary, the user then guides the stripping tool 1 along the outer sheath 2 of the cable 4 until the desired length of cable 4 for stripping is reached. If the stripping tool 1 is used in a hard-to-reach junction box or a confined electrical enclosure, the cone 18 of the end section 17 allows the stripping tool 1 to be positioned as close as possible to the desired point of use.

[0051] To strip the cable, the user then grasps the second hollow body section 13 with their thumb and forefinger and presses the hollow body shells 7 and 8 together. This presses the cable 4 onto the cutting element 10, so that when the cutting element 10 rotates around the cable 4, a cut is made that allows the outer sheath 2 to be removed. The user rotates the stripping tool 1 around the cable 4 in the usual way by twisting their wrist.

[0052] In a similar manner, the sheathing of a cable 4 can also be removed in the first hollow body part area 12, whereby the attack tabs 14 can be used to press the hollow body part shells 7, 8 together.

[0053] Furthermore, the user can also use the wire stripping tool 1 to remove the insulation 3 of a single-core cable 4. To do this, the user manually opens the first hollow body section 12 of the wire stripping tool 1 by pivoting the second hollow body section 8 of the first hollow body section 12 relative to the first hollow body section 7. This provides a view into the hollow body 9 of the wire stripping tool 1, which has a plurality of adjacent cutting elements 21 on the shell edge 19 opposite the pivot axis 5. Depending on the diameter of the wire insulation 3, the user selects a corresponding cutting element 21, which is particularly easy to identify by orienting it using the irregularly arranged ribs 23 of the guide track 22.Particularly when stripping multiple cables 4 of the same diameter, the user can identify the ridge 23 closest to the desired cutting element 21 and quickly insert the cable 4 into the stripping tool 1. The user then supports the cable 4 against the adjacent ridge 23, which essentially aligns the cable 4 relative to the cutting element 21. Additionally, the user can measure the desired length of cable 4 to be stripped using the marking 25. For example, if a length of twelve millimeters of cable 4 is to be stripped, the user inserts the cable 4 into the stripping tool 1 up to the graduation mark with the millimeter indication "12".

[0054] The Fig. Figures 10 to 18 show a second embodiment of a wire stripping tool 1, which is essentially based on the one described in the Fig. The embodiment shown in Figures 1 to 9 is based on this.

[0055] In the illustrated embodiment, a second hollow body shell 8 can be locked to the first hollow body shell 7, particularly in the shell closure position. Such a locking mechanism is shown in connection with the hollow body section 12. Furthermore, such a locking mechanism is additionally or alternatively possible in the hollow body section 13.

[0056] Each second hollow body section 8 is pivotable about an axle body 26 extending in the longitudinal direction of the respective hollow body section 12 or 13. This axle body 26 is preferably mounted at the edge of the first hollow body section 7, forming the pivot axis 5 or 6, and preferably an arrangement of the axle bodies 26 and the pivot axes 5 and 6 that is opposite each other with respect to the longitudinal extent of the stripping tool 1.

[0057] The edge areas of the first and second hollow body shells 7 and 8, which point towards each other in the joint area, are alternately nested within each other over the longitudinal extent, crossing the geometric pivot axis.

[0058] In the illustrated embodiment, a sliding locking element 27 is provided associated with the hollow body section 12. This is positioned approximately in the middle of the longitudinal extent of the hollow body section 13, on the hinge side of the arrangement.

[0059] The locking element 27 initially rests in a wall-side recess 28 of the stationary hollow body shell 7. This recess 28 is open towards the parting line between the first hollow body shell 7 and the pivotable second hollow body shell 8.

[0060] Extending from the recess 28, a locking recess 29 is formed on the outer side of the wall of the closed hollow body part shell 8, which is also open in the direction of the parting plane.

[0061] The locking element 27 is penetrated by the associated axle body 26 in the area of ​​an elongated, slot-like recess 30 oriented perpendicular to the extension of the geometric pivot axis. This allows the locking element 27 to be guided on the bottom surface of the recess 28 perpendicular to the axis orientation with essentially tangential displacement relative to the pivot axis, and furthermore, it is captive and held in place on the stripping tool 1.

[0062] The actuation or relocation of the locking part 27 can, preferably, be carried out with one hand, e.g. by applying pressure with the thumb.

[0063] Through a sliding displacement from a position like in Fig. 13 shown unlocking position into a locking position according to Fig. 14 The locking element 27 crosses the parting line between hollow body part shell 8 and hollow body part shell 7 in the hinge area (with the hollow body part area closed) and enters the area of ​​the locking recess 29 of the pivotable second hollow body part shell 8. This provides support for the hollow body part shell 8 in the opening direction against the locking element 27.

[0064] Both locking positions can be latched, as is preferred and also shown. As shown, such latching occurs between the locking part 27 and the first hollow body shell 7. The latter has an overflowing latching projection 31 facing the corresponding surface of the locking part 27 in the area of ​​the recess 28, which, in the locked and unlocked positions, engages in latching recesses 32 of the locking part 27 that are spaced apart from each other in the direction of displacement.

[0065] The outward-facing surface of the locking element 27 can be ergonomically shaped, for example, by means of a shell-like design. Furthermore, as indicated in the drawing, the surface can have a profile for improved force transmission. The surface can also be made more secure to grip, at least partially, for example, by applying soft plastic components using a two-component injection molding process.

[0066] Such a surface design favorable with regard to force transmission can also be provided in the area of ​​one or both of the attack lugs 14 (see, for example, Fig. 15).

[0067] Furthermore, the attack tabs 14 can be used according to the illustrations in the Fig. 15 to 18 not only and exclusively serve to load the associated shells in the direction of the closing position, but can also have a cutting function.

[0068] The attack tabs 14 are thus formed as functional tabs 33. These also project freely beyond the circumferential surface from the first hollow body part shell 7 and the second hollow body part shell 8, facing away from the pivot axis. In the illustrated embodiment, the functional tabs 33 are formed in the hollow body part area 12.

[0069] The functional tabs 33 are located in closed hollow body partial shells 7 and 8 (as in Fig. (15 shown) are brought into overlapping positions, whereby in this closed position a preferably round through-opening 34 is formed. This through-opening 34 is preferably formed half by half by a corresponding recess in the area of ​​the opposing surfaces of the functional tabs 33.

[0070] When the shell is closed, the through-opening 34 preferably extends in a parallel orientation to the geometric pivot axis of the associated hollow body section. Furthermore, the through-opening 34 is positioned between the functional tabs 33 such that, with reference to a cross-section transverse to the longitudinal extent of the hollow body section 12, as shown in the illustration in Fig. 12 the through-opening 34 extends laterally along the shell wall.

[0071] At least one functional tab 33 has a cutting element, preferably the functional tab 33 assigned to the pivotable second hollow body part shell 8.

[0072] The cutting edge 35 of the cutting element projects into the free cross-sectional area of ​​the through-opening 34 when the shells are closed and extends essentially in an orientation according to the geometric pivot axis of the same hollow body part area.

[0073] The through-opening 34 with the cutting element comprising the cutting edge 35 is preferably used for cutting the sheathing of a cable along its longitudinal direction, in order to facilitate stripping, particularly over longer cable lengths. During such a cutting process, the cable is drawn through the through-opening 34.

[0074] With such handling, the cable can be positioned in axial extension of the through-opening in the hollow body section 13, particularly in a corresponding section of the relevant hollow body shell 8. In this context, an externally accessible guide 36 in the form of a groove, which can be formed on the hollow body shell 8 of the hollow body section 13, proves particularly advantageous.

[0075] Although the figures only show embodiments of the invention, it is self-evident that individual sub-features can also be combined. For example, both the first hollow body section 12 and the second hollow body section 13 can carry cutting elements 21. The orientation of the pivot axis 5, 6 relative to the shell edges 19 is also variable. Furthermore, the stripping tool can have both a recess 20 and cutting elements 21 on the shell edge 19 of a hollow body section 12, 13. In addition, a conical end section 17 can, of course, also be combined. The stripping tool 1 can be designed as a right-handed or left-handed tool, with the pivot axes 5, 6 optionally being relocated to an opposite shell edge 19 between the two hollow body sections 7, 8.
