In the 1a is a perspective view of a hand tool according to the invention 1 shown. The hand tool 1 is an electrically operated stripping and crimping tool 2 educated. In the 1a is a housing 3 of the hand tool 1 recognizable, which on a side surface 4 a feed opening 5 through which a cable 6 or a jacketed wire 6 in the direction of a longitudinal axis L5 the feed opening 5 in an interior 7 of the hand tool 1 is insertable. The schematically illustrated cable 6 has a cross section Q6 on and includes a sheath 8th or an insulation 8th and a wire 9 or a wire 9 with a cross section Q9 in which the wire or the wire can also be formed by a plurality of individual cores which run parallel to one another or are twisted or intertwined with one another. On the case 3 there is a first switch 10 with which the hand tool 1 can be switched on and off. Furthermore, located on the housing 3 a display device 11 by which a user an operating state of the hand tool 1 can be displayed. In the interior 7 of the hand tool 1 is an energy source e arranged, which is preferably designed as an accumulator or rechargeable battery. The through the feed opening 5 defined longitudinal axis L5 is perpendicular to a longitudinal axis L3 of the housing 3 , The housing 3 has a long grip area GB and a work area oriented transversely to this FROM on. By positioning the workspace FROM at a free end El of the housing 3 can the hand tool 1 even in hard-to-reach places z .B. be used in cable cabinets.

In the 1b is now in a different spatial orientation, a perspective view of selected devices in the interior 7 or in the workspace of the already in the 1a shown hand tool 1 shown. The 1b shows a first position I of the devices of the hand tool 1 , From that in the 1a shown housing 3 is in the 1b to 1k only the feed opening 5 shown. The housing not shown 3 is on a base frame 12 attached, which may also be referred to as a chassis and a frame or a basic structure of the tools 1 or the stripping and Crimphandwerkzeugs 2 forms. Between two opposite straps 12a . 12b of the base frame 12 is a linear axis 13 arranged, which is merely indicated in the drawing and along a longitudinal axis L13 from the carrier 12a to the carrier not fully shown 12b runs and with the straps 12a and 12b is rotatably connected. On the linear axis 13 is a head 14 arranged. The head 14 is along the longitudinal axis L13 the linear axis 13 in the direction of the arrow z and z 'movable and about the longitudinal axis L13 the linear axis 13 in the direction of the arrow w in the clockwise direction and in the direction of arrow w 'pivoted counterclockwise. The head 14 carries a Abisoliereinrichtung 15 and a squeezing device 16 , The head 14 is in the 1b in a first tilt position K1 shown in which this counterclockwise in the direction of rotation w 'by an angle α' with respect to a median plane ME around the longitudinal axis L13 tilted down. In this position is the Abisoliereinrichtung 15 with a longitudinal axis L15 on the longitudinal axis L5 the feed opening 5 aligned, through which the cable 6 in the interior 7 of the hand tool 1 is insertable. In the 1b is still a cable holder 17 represented by which the cable 6 opposite the base frame 12 can be fixed. Between the on the head 14 arranged squeezing 16 and the carrier 12b of the base frame 12 are still three sleeves 18 or 18a to 18c, which shows the squeezing device 16 be supplied from a magazine 19, not shown. Here, the first sleeve 18a of the squeezing device 16 held. The in the 1b shown position I of the stripping and Crimphandwerkzeugs 2 is a basic position in which the stripping and Crimphandwerkzeug 2 for receiving the available cable 6 ready.

To initiate a stripping and crimping or stripping and crimping cycle, the cable becomes 6 through the feed opening 5 in the direction of the arrow z in the interior 7 of the hand tool inserted. This insertion is done by a first sensor 20 detected, the sensor 20 according to an embodiment also determines which cross section of the wire 9 of the cable 6 having an electronic control device 21 Check if the one from the first sensor 20 detected cross-section of the vein 9 to the pods 18 fits, which is in the hand tool 1 and only allow stripping and crimping if the cable 6 for the inserted pods 18 suitable is. From a second sensor 22 is monitored whether the cable 6 with a sufficient length or sufficiently deep into the interior 7 of the hand tool 1 is inserted, as in one in the 1c shown second position II is shown. If this is the case, the electronic control device initiates 21 the cable holding device 17 , the jacketed cable 6 to clamp, as shown in the figure ld in a third position III. When inserting the cable 6 from the position I to the position II, the cable 6 enters the Abisoliereinrichtung 15 and passes or passes through a core centering device 23 and a cutter 24 the Abisoliereinrichtung 15 , As another component, the wire centering device comprises 23 another control rail 25 , which with the base frame 12 is connected and the wire centering device 23 controls. The Abisoliereinrichtung 15 comprises as another component a slider 26 , In comparison of the 1c and ld is recognizable as cable knives 24a and 24b the cutting device 24 against each other in the direction of arrows x or x 'move and thereby the sheath 8th of the cable 6 up to the wire 9 incise. In comparison of the position III shown in the figure ld and a position IV shown in the figure le can be seen, as after the cutting of the sheath 8th the head 14 with the Abisoliereinrichtung 15 from its tilted down tilt position K1 in the direction of the arrow z on the linear axis 13 while maintaining its inclination in a second tilted position K2 moves. During this movement in the stripping direction z push the cable knives 24a and 24b the cutting device 24 a cut-off sheath section 8a from the vein 9 from. Back remains through the cable holder 17 held, stripped cable 6a , Furthermore, clamping wires 23a and 23b , which form two eyelets, the core centering device 23 when moving in the direction of the arrow z taken along and by the fixedly arranged on the base control rail 25 controlled so that these are the exposed vein 9 enclose closer with increasing travel and in the position IV, in which the shroud section 8a completely removed from the wire 9, fix. Furthermore, that takes on the head 14 arranged squeezing device 16 when moving in the direction of the arrow z the first sleeve 18a with. For clarity, in the figure le is the position which the first sleeve 18a before moving the head in the direction of the arrow z has taken, shown with dashed lines. In the figure le or ld is at the squeezing 16 each also a knife 27 recognizable, with which the squeezing device 16 the first sleeve 18a has already cut from the subsequent sleeve 18b, wherein the second sleeve 18b and the third sleeve 18c are still connected to each other by a thin plastic film.

In a fifth position V, which is shown in FIG. 1f, the head is 14 now from the tilted position K2 , in which this in the 1g is shown to the actuator axis 13 in a tilted position K3 clockwise in the direction of rotation w swung upwards. The head 14 is now opposite the mentioned middle plane ME at an angle α swung upwards. Thus, results for the head 14 between the tilted position K2 and the tilt position K3 a swivel angle β from α + α '. In this pivoting movement, the clamping wires 23a and 23b of the wire centering device 23 not taken. Rather, this only has the movement in the direction of the arrow z joined in the vein 9 to clamp or fix. The cutting device 24 , the slider 26 and the peeled sheath portion 8a be with your head 14 swung upwards. From the figures le and lf also shows that the second sensor 22 , which works as a limit switch, on the head 14 is stored and moved with this and tilted. By pivoting the head 14 in the position K3 became a longitudinal axis L16 the squeezing device 16 now on the longitudinal axis L5 the feed opening 5 or a longitudinal axis L6 of the cable 6 or the stripped cable 6a aligned. Thus stands the of the squeezing 16 gripped first sleeve 18a now in the longitudinal direction in alignment with the exposed wire 9 or the exposed wire 9 of the stripped cable 6a , From the tilted position K3 the head 14 now moves, as in the 1g shown with a position VI, in a fourth tilted position K4 , Wherein its movement is a pure linear movement in the sleeve pushing on direction z 'and the head 14 continues to maintain its tilted up tilt, in which the squeezing 16 on the feed opening 5 is aligned. During this movement, the head takes the clamping wires 23a and 23b the wire terminal direction 23 again with and the clamping wires 23a and 23b are by means of the control rail 25 in which they slide, reopened so that the wire 9 of the stripped cable 6a in the position VI, which in the 1g shown by the wire centering device 23 is released again. When driving back the head 14 in the direction of arrow z 'from the position V in the position VI, the cutting device opens 24 again. After the head 14 the tilted position K4 has reached, the following operations occur simultaneously or sequentially. The slider 26 which is part of a waste holding and Abfallausschiebeeinheit not shown AHA is, push the cut-off sheath section 8a in an arrow direction a into a waste channel 28 a discharge device AFV , which is designed as a groove in the 1g is the slider 26 already shown in a position in which this the cut-off jacket section 8a already pushed out. In the waste channel 28 lies in the discharge direction z before the casing section 8th another cladding section 29, which was cut and ejected in a previous stripping and crimping cycle. As a further process now runs from the actual crimping, in which the first sleeve 18a on the exposed wire 9 is squeezed. This is a lever mechanism 30 , which as a translation mechanism 31 is formed and acts on a die 32, activated. From the schematically illustrated lever mechanism 30 is compared to the 1f and 1g recognizable as one in the squeezing 16 initiated force EK is reacted in a force acting on the first sleeve 18a crushing force QK by the lever mechanism 30 around a lever bearing HL rotates, with one according to the leverage to a large extent the squeezing force QK corresponding counterforce GK in the squeezing device 16 or the head 14 is initiated so that the linear axis 13 when squeezing the full crushing force QK must catch. This squeezing is done only after the head in the tilted position K4 is, because only then the first sleeve 18a completely on the exposed wire 9 is deferred.

In the position VII shown in the figure lh is now the slide 26 the waste holding and waste ejection unit AHA moved back to its original position. Furthermore, the lever mechanism 30 solved again and the cable holding device 17 has the cable 6a released after completion of the squeezing operation, so that this as in the position VIII, which the 1i shows, through the feed opening 5 in the direction of the arrow z 'together with the crimped sleeve 18a from the interior 7 of the hand tool 1 can be pulled out.

Since pushing out the sheath section 8a which is in the 1g is shown, the cutter is located 24 with her cable knife 24b at the in the waste channel 28 inserted portion of the sheath portion 8a at. If the head 14 now in the 1i tilt position shown K4 back to the tilt position K3 in the direction of the arrow z is retracted, as shown after completion of the movement in the figure lj, then pushes the cable knife 24b here the sheath section 8a also in the direction of the arrow z to the position which previously the sheath section 29 had taken. With the sheath section 8a Also, the sheath portion 29 is further in the direction of the arrow z pushed and then falls in a later shift operation in a in the figure lj indicated by dashed lines waste container 33 , In the 1i to 1k is the waste channel 28 shown in more detail. This includes braking means 34 . 35 , which are formed as a check mark, and against in the channel 28 located sheath sections 8th . 29 are directed to prevent them in an arrow direction z 'against the conveying direction z can slip back and hinder the stripping and crimp cycle. The waste channel 28 has a length L28 which is longer than a length L8a respectively. L29 of the jacket section 8a respectively. 29 , From a position IX, which in the 1j shown is the head 14 from its tilted position K3 back to the tilt position K2 panned, which in the 1k is shown as position X. From this position X or tilt position K2 the head 14 then moves back to the one in the 1b tilt position shown K1 or position I, in which again a stripping and crimping cycle can be started.

In comparison of the 1f and 1g is recognizable as the pods 18 nachgefördert, so that the squeezing 16, if this with the head 14 from the in the 1k tilt position shown K2 in the in the 1b tilt position shown K1 goes back with a recording 34 can receive the sleeve 18b. This is where the knife separates 27 just before reaching the tilt position K1 the sleeve 18b of the sleeve 18c, so that these of the squeezing 16 can be handled independently of the sleeve 18c.

All movements are powered by drives 37 . 39 . 41 and 43 generated, which for the sake of clarity only in the 1k are shown symbolically and from the only in the 1a represented energy source 12 be fed. Here is the drive device 37 as spindle drive 38 trained and moves the head 14 in the direction of the arrows z and Z'. The drive device 39 is as an electromagnet 40 trained, which the head 14 between the tilt positions K1 and K4 respectively. K2 and K3 back and forth. The drive device 41 operates the lever mechanism 30 and is also as a spindle drive 42 educated. Also the drive device 43 through which the pusher 26 is moved, is as a spindle drive 44 educated. All drives 37 . 39 . 41 and 43 are in the grip area GB of the hand tool 1 arranged. The workspace FROM at the free end El of the housing 3 is thus available for the cable feed and those components which handle the cable.

In the 1k is schematically indicated a wear assembly VGB. This includes the cable knives 24a . 24b the cutting device 24 , the knife 27 for separating the sleeves 18, the clamping wires 23a . 23b the wire centering device 23 and wearing parts of the waste holding and waste ejecting unit AHA , The head 14 has a threaded hole for mounting these unitized components 55 on, in which the wear assembly VBG with a fastening means shown schematically 54 is fastened, which is preferably designed as a screw.

In the 2a to 2d are perspective views of selected devices in an interior 7 a second hand tool according to the invention 45 shown in various positions, which take these successively during a stripping and crimp cycle. The hand tool 45 is also a stripping and crimping tool 46 trained and is in principle comparable to that in the 1 ff. Hand tool shown constructed. In this respect is also on the description to the 1 ff. referenced. In contrast to the first hand tool, the second hand tool has two scenes as drive units 47 . 48 on. The two scenes 47 and 48 are perpendicular to each other. How to the 1 ff., is a head 14 in arrow directions z and z 'on a linear axis 13 movable and about this or its longitudinal axis L13 tiltable. In the 2a is the head 14 in a tilted position K1 , This positioning is comparable to an intermediate position between the figures ld and le, since here already one of cable knives 24a and 24b cut off jacket section 8a is deducted from a cable, not shown.

As from a comparative view of 2a and 2 B shows causes a displacement of the movable gate 47 in the direction of the arrow x a procedure of the head 14 in the direction of the arrow z and a subsequent slight tilting of the head 14 around the linear axis 13 in the direction of rotation w because the head 14 with a first pen 49 in the scenery 47 and with a second pen 50 in the scenery 48 is forced. The scenery 47 has an S-shaped slide track 51 on and the scenery 48 has a C-shaped slide track 52 on.

In the 2c Then a positioning is achieved, which is the representation of 1g corresponds, in which one in the 2c not shown on a sleeve in the 2c stripped wire, not shown, is fully ejected, in contrast to the 1g a lever mechanism 30 is not yet actuated. An actuation of the lever mechanism 30 takes place, as from a comparative consideration of 2c and 2d emerges, then through a on the backdrop 47 arranged cams 53 , From a comparative analysis of the 2c and 2d also shows that the head 14 in an upwardly tilted position K4 stops during the lever mechanism 30 is pressed. After the head 14 in an upwardly tilted position K4 the scenery remains in motion 47 with the cam 53 thus only the lever mechanism 30 at. Overall, the scenes are used 47 and 48 for controlling the movement of the head 14 , passing through the scenes 47 and 48 successive traversing and pivoting movements are generated. During the crimping process is the head 14 quiet.
