Description

Technical Field

[0001] The present invention relates to a tool capable of, on the one hand, cutting a cable to a desired length and, on the other hand, effecting a peeling cut on an end portion range of the insulating jacket of the cable. Further, the present invention relates to a tool assembly having tools of different configurations.

Background Art

[0002] Patent Document 1 discloses a peeling plier having a fixed plier portion including a fixed handle lever, a fixed plier jaw portion, and a movable handle lever connected to a movable plier jaw portion via a knee lever drive portion. The peeling plier is provided with a separating cutter, and the separating cutter is fixed to the movable handle lever and is pivoted by the handle lever in the direction of the other separating cutter to generate a closing movement. It is possible to effect a cut of the cable for the same cut to a desired length using the separating cutter. Further, the peeling plier is provided with a peeling cutter guided at the plier jaw portion. The closing movement of the handle lever and thus the plier jaw portion is divided into a cutting portion stroke and a peeling portion stroke. In the cutting portion stroke, the peeling cutter cuts on the opposite side of the insulating jacket of the cable inserted into the plier gripping opening. The peeling cutter is supported by a carriage displaceable in the longitudinal direction of the cable inserted into the plier gripping opening. In the peeling portion stroke, the peeling cutter moves in the longitudinal direction of the cable so that at least a partially pre-cut end portion range of the insulating jacket is peeled off from the cable using the peeling cutter by the movement of the carriage caused by the handle lever.

[0003] Patent Document 2 discloses a clipper tool having a first clipper part and a second clipper part that are pivotally supported about a pivot axis via a clipper bearing. In an end range opposite to the clipper bearing, these clipper parts each have a finger receiving part, and through the finger receiving part, it is possible to cause the clipper parts to pivot in the closing direction. The clipper tool has three workpiece processing ranges, and in these workpiece processing ranges, by closing the clipper parts, it is possible to cut or sever one workpiece each. In the first workpiece processing range closest to the clipper bearing, both clipper parts each have a pair of cutting cutters, and using the cutting cutters, the cutting of the insulation jacket of the flat ribbon cable is performed by the closing movement of the clipper parts, and using the subsequent axial movement, the cut insulation part is peeled off from the flat ribbon cable. In the central second workpiece processing range, one clipper part forms a receiving part with its edge closed for a cable having a circular cross-section. The other clipper part supports a cutting cutter in the second workpiece processing range, and the cutting cutter cuts into the insulation part of the cable arranged in the receiving part by the closing movement of the clipper parts. By pivoting the clipper tool about the cable, the insulation part can be cut in the circumferential direction, and by the subsequent axial movement, it is possible to peel off the end range of the insulation part separated by the surrounding cuts. Finally, the clipper tool has an open cutting recess of the clipper part in the outermost third workpiece processing range, and a cable and a cutting cutter supported by the other clipper part can be inserted into the cutting recess. By the closing movement of the clipper parts, the cable inserted into the cutting recess can be cut or severed using the cutting cutter. The cutting cutter in the second workpiece processing range and the cutting cutter in the third workpiece processing range are formed by a common blade body part. The blade body part is pivotally supported about the pivot axis in the assigned clipper part.The back of the cutting body is supported by a knurled bolt away from the swivel bearing. By adjusting the knurled bolt, the cutting depth of the cutting cutter into the second workpiece processing range or the cutting depth of the cutting cutter in the third workpiece processing range can be adjusted.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The underlying problems of the present invention are a) the cutting of cables, and also b) the installation of a peeling cut at the end range of the cable insulation jacket to be made possible, - manufacturing costs and / or - available materials and / or - available manufacturing methods for components and / or - installation in the factory and / or - the number of necessary components and / or - structural dimensions and / or - operating comfort and / or - structural dimensions and visual configuration It is to propose a tool improved in this regard.

[0007] Furthermore, the problem underlying the present invention is to propose a tool group having at least two different embodiments of a tool, which is improved with respect to the manufacturing effort and the stocking effort for the components.

Means for Solving the Problem

[0008] The problem of the present invention is solved by the features of the independent claims according to the present invention. Another preferred configuration according to the present invention can be understood from the dependent claims.

[0009] According to the present invention, first, it is proposed that the tool for cutting and providing the peeling cutting part is not formed as a plier tool, but rather as a clipper tool. In this case, the clipper tool includes a first clipper part and a second clipper part. Both clipper parts are supported by each other via a clipper bearing so that they can pivot relative to each other about a clipper pivot axis set by the clipper bearing.

[0010] Both clipper parts each have one finger receiving part, and at least one finger of the user, particularly the thumb and index finger or middle finger, can be inserted into the finger receiving part where the closing force of the finger can be applied to the clipper part, so that the clipper part can be manually brought in the closing direction via the finger receiving part. At this time, the edge of the finger receiving part may be open. However, preferably, the finger receiving part is formed with its edge closed (for example, as a circular through recess, an elliptical through recess or a recess with the edge of any other shape of the clipper part closed).

[0011] The clipper parts each have a separating cutter. The separating cutters move toward each other by the turning of the clipper parts in the closing direction caused by the closing force of the fingers brought about by the user in the finger receiving part. If a cable is between the separating cutters, it is possible to cut the cable in this way. Therefore, the clipper tool ensures the first desired function of enabling cable cutting.

[0012] According to the present invention, it is proposed that the finger receiving part of the first clipper part is integrated into the operating element. The clipper tool has a peeling cutter in addition to the separating cutter. The peeling cutter is movably guided in the first clipper part. The present invention proposes that the operating element integrated into the finger receiving part is coupled to the peeling cutter via a drive coupling part. When the user operates the operating element, it is possible to move the peeling cutter to a desired position. Therefore, in the present invention, the finger receiving part of the first clipper part is used multifunctionally. This is because, on the one hand, it is possible to bring about the closing movement of the cutting cutter for cutting the cable through the finger receiving part, and on the other hand, it is possible to bring about the movement of the peeling cutter to a desired position through the operating element integrated into the finger receiving part.

[0013] In the present invention, it is possible to form any drive coupling part, particularly a kinematic coupling part, a lever coupling part or other coupling part, which may also involve the conversion or deceleration of force and motion in some cases. Preferably, since a fixed coupling part is used as the drive coupling part, on the one hand, the operating element and the peeling cutter are fixed to each other.

[0014] Preferably, the finger receiving portion of the first clipper part has two circumferential ranges that are separated from each other and shifted in the circumferential direction. When both fingers of the user are inserted into both finger receiving portions of the clipper part and the clipper part is operated to cause the closing movement of the separating cutter, the fingers act on the first circumferential range of the finger receiving portion of the first clipper part. And since the closing force of the fingers generated at this time is directed in the circumferential direction centered on the clipper bearing, the first circumferential range has a plane normal generally directed in the circumferential direction centered on the clipper bearing. In order to avoid an accidental operation of the operating element during the manually induced movement of the separating cutter, the operating element is arranged outside the circumferential range, that is, in the second circumferential range. And the second circumferential range in which the operating element is arranged can be arranged in any other circumferential range. For example, it is possible that the second circumferential range is arranged on the opposite side to the first circumferential range, or the plane normal of the second circumferential range is generally directed in the direction of the clipper bearing, and a difference of ±30°, ±20° or ±15° of the plane normal of the second circumferential range with respect to the joint with the swivel bearing is also possible.

[0015] Regarding another proposal of the present invention, the clipper tool is provided with a spring device that loads the peeling cutting cutter to the initial position. At this time, the initial position may be the insertion position, and thus, the user needs to apply a force to the operating element to generate a cutting force in a direction against the action of the spring device, and the load of the spring device increases by the operation of the operating element. However, preferably, the peeling cutting cutter is loaded in the direction of the cutting position via the spring device. Thereby, the spring device automatically generates a force that presses the peeling cutting cutter against the insulating jacket of the cable and thus makes a cut in the insulating jacket. By setting the strength and length of the spring device, it is possible to structurally preset the force characteristics regarding the pressing of the peeling cutting cutter in the insulating jacket. However, in order to enable the insertion of the cable into the operating range of the peeling cutting cutter, it is necessary to move the peeling cutting cutter from the cutting position to the insertion position while increasing the load of the spring device. This can be done by the operation of the operating element by the user.

[0016] Another possible influence on the pressing characteristics of the peeling cutter on the insulating jacket lies in the fact that the spring device can be biased. In this way, for example, the basic level of the spring force of the spring device at the insertion position can be set according to the scale of the biasing, while on the other hand, through the selection of the spring strength, the increase in the spring force from the basic level can be set depending on the movement of the peeling cutter from the insertion position to the cutting position, whereby, for example, it is possible to adapt to different diameters or insulation thicknesses of the cable to be peeled and / or different materials of the insulating jacket that require different fittings of the peeling cutter.

[0017] In the present invention, "cutting" is understood to mean that the process performed by the clipper tool does not necessarily have a peeling stroke in which the workpiece cut by the peeling cutter is automatically peeled off, but rather at least one partial range of the insulating jacket of the cable is cut.

[0018] In one embodiment of the clipper tool according to the present invention, the operating element projects into the finger receiving portion of the first clipper part. Preferably, when the operating element moves to the insertion position, the maximum movement of the operating element (and thus the peeling cutter) that can be brought about by using the fingers in the finger receiving portion is limited. At the insertion position, the operating element and the defining portion of the finger receiving portion of the first clipper part are arranged in a straight line with each other. Thus, in other words, the scale at which the operating element projects into the finger receiving portion of the first clipper part sets the maximum stroke of the operating element up to the insertion position.

[0019] Regarding the configuration of the above components, any material and / or manufacturing method can be used. The spring device can be formed, for example, of one or more metal springs of any structure (particularly leaf springs, torsion springs, coil springs, and the like in the configuration as tensile springs or compression springs). Regarding the special proposal of the present invention, the operating element, the peeling cutting cutter, and the spring device are formed of a single member. In this case, the spring device is formed by an elastic material range. Within the scope of the present invention, for example, it is possible to form (manufacture) a single member of the operating element, the peeling cutting cutter, and the spring device from a synthetic resin, and the formation (manufacture) can be performed by an injection molding method or an additional method, particularly in 3D printing. Merely for the purpose of giving an example, the operating element and the peeling cutting cutter can be formed by a block-shaped or plate-shaped cut body part, and at least one arbitrarily formed spring arm extends from the cut body part as a single member, and the spring arm forms the spring device. In this case, the spring strength of the spring device is obtained from the elastic modulus and geometry of the material used, the cross-section of the spring arm, particularly the length of the spring arm, and the area moment of inertia of the spring arm.

[0020] The present invention proposes, for another proposal, that (unlike classical clippers) the first clipper part forms a housing having an internal space. And the internal space can be used such that at least one (preferably movable) component of the clipper part is supported, guided, and / or arranged therein. Thus, for example, in the internal space, a part of the operating element, a peeling cutter, a spring device, and / or a partial range of the peeling cutter can be supported, guided, and / or arranged. The clipper bearing or the clipper bearing pin can extend through the internal space. Further, the separating cutter can be arranged at least partially within the range of the internal space, and the separating cutter can also move out of the internal space by a closing stroke. Preferably, the housing comprises two housing parts, which housing parts have, for example, a central or eccentric partial plane. The housing can comprise a housing body closed by a housing cover.

[0021] For the above-described configurations, the following alternative or additional other possibilities of configuration exist: - Both housing parts, in particular the housing cover and the housing body, can be joined to each other by engagement, locking engagement, or fitting (or only by these). For merely giving an example, the engagement protrusion of the housing part can engage with the engagement recess of the other housing part. At this time, the engagement action can be affected by the elasticity of the support part of the engagement protrusion and / or the engagement recess, the inclination angle, and the configuration (shape) of the contact surface between the engagement protrusion and the engagement recess. - In the simplest case, at least one housing part comprises an engagement hook that engages with the corresponding engagement recess of the other housing part. - The above-described joint can be the only joint between both housing parts. Additional screwing of the housing parts, adhesion of the housing parts, or welding of the housing parts to each other can also be performed. - Sealing can also be performed between the housing parts. - The housing part, in particular the housing cover and / or the housing body part, can have a protrusion, a rib, a recess or a groove. At this time, the protrusion, the rib, the recess or the groove can ensure the guidance of components that move via the stroke of the operating element and / or the stroke of the separating cutter (for example, the operating element and / or the peeling cutter). It is also possible for the protrusion, the rib, the recess or the groove to provide a stopper for the movement of components (especially the operating element and / or the peeling cutter). Just to give another example, the protrusion, the rib, the recess or the groove can be used to support the spring base point of the spring device. - The protrusion, the rib, the recess or the groove can be used to accommodate or support the fixed separating cutter and / or protect the peeling cutter against escape from the recess of the peeling cutter in the direction opposite to the mounting direction. - Instead of or in addition to this, the protrusion, the rib, the recess or the groove can also provide a cable contact surface, and the cable contact surface supports on the opposite side of the peeling cutter the curve to be cut and peeled, and the cable contact surface can also support a support rib or a support lip or an engagement rib or an engagement lip or the peeling cutter. - The housing cover and / or the housing body part can be formed of synthetic resin.

[0022] Regarding the special configuration of the present invention, the first clipper part (here, for example, the housing part) and / or the second clipper part is provided with a receiving part. In the receiving part, the assigned separating cutter can be arranged and supported. This will be described based on the following examples that do not limit the present invention: The receiving part can be formed as a recess whose depth and contour correspond to the thickness and shape of the separating cutter. And when the separating cutter is fitted into the receiving part, the separating cutter is engagedly accommodated and supported in a plane transverse to the fitting direction. Preferably, the separating cutter is fitted into the receiving part in a fitting direction parallel to the clipper pivot axis. After fitting, the separating cutter can be arranged in a straight line with respect to the upper side of the clipper part, or can be retracted inward or protruded outward with respect to the upper side of the clipper part.

[0023] Regarding another proposal of the present invention, the clipper tool is provided with (only one or at least one) bolt. Here, the bolt sets the clipper pivot axis. At this time, the shaft part of the bolt forms a clipper bearing pin. Instead of or in addition to this, by using the bolt of the bolt, it is possible to set the pressing of the clipper parts against each other according to the tightening torque. And in this way, the bolt can adjust the required operating force and the frictional force that guarantees the position of the clipper part through the bolt in order to provide friction against the turning of the clipper part around the clipper bearing. Instead of or in addition to this, by using the bolt of the bolt, it is possible to set the cutting play of the separating cutter. Therefore, the bolt can be used in a multifunctional manner. In addition to at least one of the above functions, the bolt can also guarantee the mutual fixation of the components of the housing part or the sub-assembly unit.

[0024] Another proposal of the present invention is directed towards simplifying the attachment of the clipper tool. In this regard, it is proposed that (preferably all) components of the clipper tool be joined in the same attachment direction, which is oriented parallel to the clipper pivot axis. With this configuration, automated attachment is possible using a robot that only needs to effect the joining of the parts in one attachment direction for attachment. Thus, in this case, handling and rotation of components or sub-assembly units during attachment are not required.

[0025] In the clipper tool, on the one hand, the cutting edge of the stripping cutter and, on the other hand, the cable contact surface are oriented parallel to each other, and it is possible for a cable to be clamped between these cutting edges and the cable contact surface. At this time, the cable contact surface is fixedly arranged on the first plier part, and the cable contact surface can be provided with a cutting edge or a support lip or a support rib. Regarding a special proposal of the present invention, the cutting edge of the stripping cutter is inclined at an acute angle with respect to the cable contact surface, and the acute angle may be, for example, 1 to 20°, 2 to 15° or 3 to 10°. Such an inclination of the cutting edge of the stripping cutter with respect to the cable contact surface has been found to be particularly advantageous if the cable is rotated over the entire circumference for the cut of the insulating jacket so that the cutting edge can cut into the entire circumference of the insulating jacket. Depending on the circumstances, different cutting depths of the cutting edge of the stripping cutter into the insulating jacket of the cable occur depending on the cutting edge and thus the rotation direction of the cable with respect to the clipper tool.

[0026] The components of the clipper tool can be formed of a synthetic resin, and the synthetic resin can be a bioplastic (bio-based synthetic resin), that is, a biodegradable synthetic resin. The components that can be formed of the synthetic resin can be, for example, a housing part, an operating element, a stripping cutter holder and a spring device, and the cutting body part of the second clipper part. Preferably, all components can be formed of synthetic resin except for at least one stripping cutter, a separating cutter and a bolt, while the stripping cutter, the separating cutter and the bolt can be formed of metal.

[0027] Another solution to the problem underlying the present invention proposes a tool group. The tool group comprises at least one clipper tool and at least one plier tool. On the one hand, the clipper tool and on the other hand, the plier tool are used for different applications. Such a tool group can be manufactured and provided, for example, by a manufacturer, and a customer can purchase only the clipper tool, only the plier tool or both tools from the manufacturer. Similarly, such a tool group can be held and provided in bearings by commercial intermediaries. It is also possible for such a tool group to be prepared and used by consumers.

[0028] In the tool group according to the present invention, the clipper tool is formed as described above. The present invention proposes that the clipper tool and the plier tool of the tool group comprise the same separating cutter. In this case, the separating cutter of the clipper tool is operated via the pivoting of the clipper part of the clipper tool, while the separating cutter of the plier tool is operated via the pivoting of the plier handle lever of the plier tool. For example, the plier tool can be formed as described at the beginning with respect to Patent Document 1 and supplemented and described in detail in that document. By providing the same separating cutter for the clipper tool on the one hand and the plier tool on the other hand, the number of identical components increases, so that the manufacturing costs can be reduced. Depending on the circumstances, the separating cutter is a wearing part, and since the same separating cutter for two different tools can be provided, the customer's stock effort for replacing the separating cutter for the clipper tool and the plier tool is reduced. At this time, the plier tool can provide an extended function scale compared to the clipper tool. In the case of the plier tool according to Patent Document 1, the plier tool guarantees, on the one hand, the cutting of the cable using the separating cutter and, on the other hand, the occurrence of the cut part stroke and the peeling part stroke using the peeling cutting cutter.

[0029] Advantageous developments of the present invention are apparent from the respective claims, the description and the drawings.

[0030] The advantages listed in the specification for the features and combinations of features are merely exemplary, and the advantages may not necessarily be achieved by the embodiments according to the present invention, and alternatively or additionally, may act differently.

[0031] Regarding the application documents at the time of filing and the disclosure content of the patent (not the scope of protection), the following matters apply: Further features can be understood from the drawings, particularly from the geometric shapes shown, the relative dimensions of the plurality of members with respect to each other, and their relative arrangements and functional couplings. Combinations of features of different embodiments of the present invention or features of different claims can similarly be different from the selected citation of the claims and are hereby recommended. This also applies to features shown in separate drawings or mentioned in their descriptions. The features can also be combined with the features of different claims. Similarly, the features described in the claims can be omitted for another embodiment of the present invention, but this does not apply to the independent claims of the granted patent.

[0032] The features listed in the claims and the specification can be understood to have exactly that number or a number greater than the number described, without the need to explicitly use the adverb "at least" regarding their number. Thus, for example, when referring to one element, this can be understood to mean exactly one element, two elements, or more elements. The features described in each claim can be supplemented by other features or can be one feature that the subject of each claim possesses.

[0033] The reference signs included in each claim do not limit the scope of the subject matter protected by each claim. The reference signs are merely for the purpose of making each claim more easily understandable.

[0034] The present invention will be further described below based on the preferred embodiments shown in each drawing.

DETAILED DESCRIPTION OF THE INVENTION

[0036] Each figure shows a clipper tool (scissors tool) 1. The clipper tool 1 includes three components or assemblies that are relatively movable with respect to each other during operation, namely, - It is pivotally supported via a pivot bearing 4 about a clipper pivot axis oriented perpendicular to the plane of FIGS. 1 to 4, and includes a first clipper portion 2 and a second clipper portion 3 that are pivotable relative to each other in a separation stroke. - A cutting unit 6 that is movable relative to the first clipper portion 2 in a cutting stroke is provided.

[0037] In the exploded view according to FIG. 6, the clipper tool 1 includes the following components: - A housing cover 7, - Bolts 8, - Two separation cutters 9, 10, - A cutting unit 6 formed of a single member here, - A peeling cutter 11, - A housing main body 12 It can be seen that it only includes these.

[0038] The separation cutters 9, 10 are formed in an L shape with two curved side members 13, 14. In each figure, the side members 13, 14 of the separation cutter 9 are indicated with "a", while the side members 13, 14 of the separation cutter 10 are indicated with "b" (see FIG. 6). In the transition range of the side members 13, 14, holes 15 indicated by "a" or "b" are similarly arranged.

[0039] The first clipper portion 2 includes a lever-shaped main body 16 having lever portions 17, 18. A cylindrical protrusion 19 is arranged in the transition range of the lever portions 17, 18. Since the diameter of the protrusion 19 corresponds to the diameter of the holes 15 of the separation cutters 9, 10 (with a clearance or play), the separation cutters 9, 10 can be attached to the protrusion 19.

[0040] The protruding portion 19 is surrounded by the accommodating portion 20 (see FIG. 5). The depth of the accommodating portion 20 preferably corresponds to the thickness of the separating cutter 10. Further, the outer contour of the accommodating portion 20 corresponds to the outer contour of the separating cutter 10. Therefore, by attaching the separating cutter 10 to the protruding portion 19, the separating cutter 10 can be fitted into the accommodating portion 20, and thereby, the separating cutter is accommodated in an engaging manner in the accommodating portion 20. At this time, the lever portion 17 supports the side member 13a forming the cutting edge of the separating cutter 10 at the bottom of the accommodating portion 20 both in the circumferential direction around the clipper pivot axis 5 and in the supporting direction.

[0041] If the separating cutters 9, 10 are attached to the protruding portion 19, the separating cutters 9, 10 are held by the bolts 8 to the main body portion 16, and the separating cutters 9, 10 are captured between the heads of the bolts 8 and the main body portion 16. At this time, the shaft portions of the bolts 8 extend through the holes 15a, 15b of the separating cutters 9, 10. In the end range of the bolts 8 opposite to the heads protruding from the separating cutters 9, 10, the threaded portions of the bolts 8 are screwed into the holes 24 of the protruding portion 19. If the protruding portion 19 is formed of synthetic resin, the bolts 8 can be screwed in a self-tapping manner into the cylindrical holes 24 of the stud 19. At this time, the tightening torque of the bolts 8 determines, on the one hand, the cutting play of the separating cutters 9, 10 and, on the other hand, the friction between the separating cutters 9, 10 during the movement of the clipper portions 2, 3. The main body portion 16 forms an attachment unit together with the separating cutters 9, 10 by screwing in the bolts 8. The attachment unit is pivotally coupled to the housing cover 7 by the heads of the bolts 8 being snugly received in the holes 22 of the housing cover 7.

[0042] As can be seen in FIGS. 6 and 7, the housing cover 7 is provided with a receiving portion 21. The depth of the receiving portion corresponds to the thickness of the separating cutter 9, and the outer contour of the receiving portion conforms to the outer contour of the separating cutter 8. By fitting, the separating cutter 9 is engaged and received in the receiving portion 21. As a result of the engaged accommodation of the separating cutter 10 in the receiving portion 20 of the main body portion 16 and the engaged accommodation of the separating cutter 9 in the receiving portion 21 of the housing cover 7, the relative turning of the first clipper portion 2 and the second clipper portion 3 leads to the relative turning of the separating cutters 9, 10. Thereby, the separating cutters 9, 10 can shift from the insertion position to the separating position (and vice versa).

[0043] The main body portion 16 is also provided with a protruding portion 23 on the side facing the housing main body portion 12, and the protruding portion is received in the hole 26 of the housing main body portion 12 (with play or clearance).

[0044] The cutting unit 6 includes a cutting main body portion 27 formed of a single member from synthetic resin. The cutting main body portion 27 includes a tongue-shaped operation element 28, a peeling cutting cutter holder 29, and a spring device 30 having two spring arms 31, 32 here. The spring arms 31, 32 are each formed in a gooseneck shape (S shape), V shape, U shape, or Z shape and can be bent by their original elasticity, and the spring arms 31, 32 are subjected to bending. The spring arms 31, 32 each have a protruding portion 33, 34 or a hook-shaped end range in the end range opposite to the peeling cutting cutter holder 29.

[0045] The peeling cutting cutter holder 29 is provided with an internal space 35, and a peeling cutting cutter 11 can be fitted into the internal space through a side mounting opening 36. On the side opposite to the mounting opening 36, the peeling cutting cutter holder 29 forms a stopper receiving portion 37. Further, a protruding portion 38 extends from the peeling cutting cutter holder 29 parallel to the operation axis 40 of the operation element 28.

[0046] As can be particularly seen from FIGS. 2, 4, 5, and 9, the housing main body 12 forms a rib 39, and the height of the rib generally corresponds to the thickness of the cutting main body 27. At this time, the rib 39 is oriented parallel to the operation axis 40 of the operation element 28. In the rib 39, since the side surface of the cutting main body 27 is slidably guided, the cutting main body 27, and thus the operation element 28 and the peeling cutter 11, can move only in the direction of the operation axis 40. Further, the rib 39 forms a housing portion that guides the protruding portion 38 of the cutting main body 27. The end face side of the protruding portion 38 is pressed against the stopper formed by the rib 39 against the biasing force of the spring device 30, thereby setting the end position of the movement of the peeling cutter 11 and the operation element 28. Further, the rib 39 can form a protruding portion 41 that contacts the defining portion of the contact recess 37 to limit the stroke of the cutting main body 27.

[0047] Furthermore, the rib 39 or the protruding portion forms a cable contact surface 43, and a cable can be installed on the cable contact surface at the insertion position of the cutting unit 6. Due to the spring force of the spring device 30, the cable is biased between the cable contact surface 43 and the cutting edge of the peeling cutter 41.

[0048] The rib 39 can form housing recesses 44, 45, and the protruding portions 33, 34 of the spring arms 31, 32 can be housed in the housing recesses to fix the spring bases of the spring arms 31, 32 to the housing main body 12.

[0049] The clipper tool 1 is attached as follows:

[0050] First, the separation cutter 10 is attached to the protruding portion 19 of the main body 16 and fitted into the housing portion 20 of the main body 16.

[0051] Subsequently, the separation cutter 9 is attached to the protruding portion 19 of the main body 16.

[0052] Finally, bolt 8 is inserted through holes 15a and 15b and screwed into hole 24 of protrusion 19.

[0053] Subsequently, the mounting unit thus formed is fitted into hole 26 of the housing main body 12 together with protrusion 23.

[0054] In parallel, by fitting the peeling cutter 11 into the internal space 35 of the peeling cutter holder 29 through the mounting opening 36, it is possible to form another partial mounting unit.

[0055] And the partial mounting unit can be fitted to the housing main body 12 by fitting projections 33 and 34 into the housing recesses 44 and 45 here, so that the free spring bases of the spring arms 31 and 32 are supported at the rib 39. At the same time, a part of the peeling cutter holder 29 is fitted between the ribs 39 extending in parallel. As a result, at the same time, the stopper 42 enters the stopper housing portion 37, and the protrusion 38 is received so as to be guided between the parallel portions of the ribs. The operating element 28 is also received so as to be guided between two parallel portions of the rib 39. If the peeling cutter holder 29 is thus fitted between the ribs 39, the peeling cutter 11 does not come out of the mounting opening 36. This is because the mounting opening 36 is closed by the rib 39 in the removal direction.

[0056] And in the next step, the housing cover 7 can be attached to the housing body portion 12, whereby a closed housing 46 is formed, and in its internal space 47, a body portion 16 having separating cutters 9, 10, a spring device 30, a peeling cutting cutter holder 29, an operating element 28, and a peeling cutting cutter 11 are arranged. The connection between the housing cover 7 and the housing body portion 12 is made via elastic locking hooks 48 arranged around the housing body portion 12, and the locking hooks are locked in locking recesses 49 of the housing cover 7. Preferably, the two locking hooks 48 and the locking recesses 49 are arranged directly adjacent to a separating cutter engagement opening 57 formed by the separating cutters 9, 10 into which a cable can be inserted for cutting.

[0057] The mounting direction for the above mounting step is basically directed parallel to the clipper pivot axis 5. The loose fitting of the peeling cutting cutter 11 to the peeling cutting cutter holder 29 is performed perpendicular to the operating axis 40.

[0058] The lever portion 18 of the body portion 16 forms a finger receiving portion 50 formed as a circular hole in the outer end portion range. The housing 46 also forms a finger receiving portion 51. For this purpose, the housing cover 7 and the housing body portion 12 are provided with through holes 52, 53 that are in a straight line (overlapping each other).

[0059] At the insertion position of the peeling cutting cutter 11 according to FIG. 1 where the operating element 28 is loaded by the finger force 54 on the end face side in the finger receiving portion 51, the operating element 28 and thus the peeling cutting cutter holder 29 having the peeling cutting cutter 11 are pushed into the internal space 47 of the housing 46 while receiving the load of the spring device 30, and the end face side is preferably formed in the same plane as the finger receiving portion 51.

[0060] The housing cover 7 and the housing main body 12 are provided with insertion openings 55a, 55b, 56a, 56b in a straight line. In the illustrated embodiment, there are pairs of insertion openings 55a, 55b and 56a, 56b in a straight line respectively.

[0061] In the intermediate space between the cable contact surface 43 and the cutting edge of the stripping cutter 11, at the insertion position, since it is accessible through the insertion openings 55, 56, it is possible to insert a cable that also has a free end range according to the length of the end portion of the insulating jacket to be removed. If the cable contact surface 43 and the cutting edge of the stripping cutter 11 are inclined at an acute angle to each other, it is possible to use the pairs of insertion openings 55a, 55b and 56a, 56b to generate incisions into cables having different diameters or different hardnesses of the insulating jacket.

[0062] The clipper tool 1 can be used as follows:

[0063] If the clipper parts 2, 3 are in the open position according to FIG. 1, the cable can be inserted into the separation cutter holding opening 57 formed between the separation cutters 9, 10. When the second clipper part 3 is turned in the closing direction 58, the separation cutters 9, 10 move towards each other and close, thereby cutting the cable. During the generation of the closing movement, two fingers, particularly the thumb and the index finger or the middle finger, are in the finger receiving parts 50, 51. And the finger arranged in the finger receiving part 51 generates a closing force in the first peripheral range 59 of the finger receiving part 51, and the surface normal of the first peripheral range is generally perpendicular to the coupling axis having the turning axis 5 or is directed in the circumferential direction of the turning axis 5.

[0064] On the other hand, when the cable should be cut by generating a cut in the insulating jacket, the user inserts a finger, particularly the thumb, into the finger receiving portion 51 while gripping the housing 46 with the remaining hand. Then, the finger force 54 can be applied to the operating element 28 by the finger disposed in the finger receiving portion 51, whereby the peeling cutter holder 29 and the peeling cutter 11 disposed thereon shift from the cutting position according to FIG. 3 to the insertion position according to FIG. 1. And it is possible to insert the end range of the cable into the respective insertion openings 55, 56. When the finger force 54 is removed, the spring device 30 presses the peeling cutter holder 29 having the peeling cutter 11 against the jacket surface of the cable supported on the opposite side at the cable contact surface 43, thereby causing a partial circumferential cut to the insulating jacket. If only the partial circumferential range of the insulating jacket should not be cut, the user can also cause a relative rotational movement between the cable and the housing 46, whereby the cutting edge of the peeling cutter 11 moves along the circumference of the insulating jacket. When the cutting depth of the peeling cutter 11 should be continuously increased, it is also possible to make a turn exceeding 360°. This is not always the case, but at the end of the cut, a relative movement of the clipper tool 1 with respect to the cable in the direction of the longitudinal axis of the cable can also be performed, whereby the pre-separated end portion of the insulating jacket can be peeled off using the peeling cutter 11. If the insulating jacket is not pre-cut along the entire circumference, it is possible to perform peeling in the remaining residual circumferential range.

[0065] In the finger receiving portion 51, the end face side to be operated of the operating element 28 is disposed in the second circumferential range 60. The first circumferential range 59 and the second circumferential range 60 are arranged offset from each other. For example, the surface normal of the second circumferential range 60 can be inclined in the direction of the coupling axis with the clipper rotation axis 5 or at an angle of ±30° with respect thereto.

[0066] The separating cutters 9, 10 can contact each other (or form a minimum gap) at their cutting edges in the separating position. However, it is also possible to arrange the separating cutters 9, 10 so that they overlap in the final position in such a way that the cutting edges of the separating cutters 9, 10 pass by each other by closing, creating a so-called bypass cross-section. Preferably, the separating cutters 9, 10 are formed as an integral part.

[0067] The cable contact surface 43 can likewise be provided with a stripping cutter or a synthetic resin lip or a synthetic resin rib. When the cable rotates relative to the clipper tool 1, the synthetic resin lip or the synthetic resin rib can enter the pre-cut range of the insulating jacket, thereby ensuring additional guidance using the synthetic resin lip or the synthetic resin rib.

[0068] The body part 16 can be provided with a finger recess 61 adjacent to the finger receiving part 50 and capable of supporting another finger of the user. For example, in order to operate the separating cutters 9, 10, the thumb can be placed in the finger receiving part 50, the index finger can be supported in the finger recess 61, and the middle finger can be placed in the finger receiving part 51.

[0069] The cover can also be closed in the area of the hole 22. When the housing cover 46 is already closed, it is also possible to screw a bolt through the hole 22 of the housing cover 7.

[0070] It is also possible to avoid the cut-off remainder of the insulating jacket from entering the internal space 47 of the housing 46 by its interaction with the protrusion 38 and the rib 39.

[0071] For the illustrated embodiment, the housing is not divided in the center. In this case, the rib 39 is formed only in the housing body part 12 or mainly in the housing body part 12, while the housing cover 7 is not provided with ribs. However, other suitable divisions of the housing 46 are possible.

[0072] The main body 16 of the second clipper portion 3 enters the internal space 47 through the clipper portion opening 62 of the housing 46. Then, the main body 16 extends through the internal space 47, and the main body 16 and / or the assigned separation cutter 10 exits the internal space 47 through the separation cutter opening 63 in the range of the separation cutter holding opening 57.

[0073] Figures 11 and 12 show a plier tool (punch tool) 64. Through the plier hand levers 65, 66, on the one hand, the separation movement of the separation cutters 9, 10 of the plier tool 64 can be brought about. Further, the strokes of the plier hand levers 65, 66 can also be used to push against the insulating jacket so as to cut the peeling cutting cutter in the cutting portion stroke, and in the subsequent peeling portion stroke, to pull away the cut end portion by the movement of the carriage holding the peeling cutting cutter. For other structural features and functions of the plier tool 64, reference is made to Patent Document 1, and the related content is the subject of the present invention. On the one hand, for the clipper tool 1 and on the other hand for the plier tool 64, preferably the same pair of separation cutters 9, 10 is used, and in the pair of separation cutters 9, 10 (as described above), it is possible to use the same separation cutter.

[0074] After the direct cutting of the insulating jacket by the peeling cutting cutter 11, it is possible to pull away the cut or severed end portion of the insulating jacket by the clipper tool 1 according to FIGS. 1 to 10. However, it is also possible that the cut or severed end portion of the insulating jacket remains on the conductor (conducting wire) at its initial position or is partially pulled away (and in some cases peeled off thereby), whereby the end portion protects the conductor against the spread of the strands (strands, cords) of the cable, for example. And the pulling away of the end portion can be carried out later only when the connection portion to the end of the conductor released from the end portion is to be joined.
