Abstract

  The present invention relates to a new insulation peeling head that can be used as a spare part for an existing rotary insulation peeling apparatus. While particularly robust and simple to manufacture, it also provides similar or improved accuracy. It has a centering jaw (4) that can pivot substantially on the side with the insulation stripping blade (3) and can rotate together about the main axis (1) via an insulation stripping operation.

Description

  The present invention relates to a rotary insulation peeling head for a conductor insulation peeling apparatus having conductors arranged along a main axis, in particular, a multilayer insulation (coaxial cable), an optical fiber, an insulation wire and the like. However, in particular the present invention does not work in a continuous process, i.e. it enters on one side of the machine and again the continuous cable present on the other side of the machine is not fed, but instead is guided to the machine on one side and again from the machine. There is no particular limitation on the insulation stripping device into which the cable to be removed in the opposite direction is fed.

  Many such insulation strippers are known in the art. The world's most popular and popular devices for coaxial cables originate from the applicant, but some have been designed with model numbers such as HC207, MP257, MP8015, MC252, CS5300, CS5300MX, CS5400. In order to strip the insulation from the optical fiber, the applicant has also successfully marketed a device with the model number FO7045 on the market. Patents such as US-A-5,361,384, US-A-5,243,882, US-A-5,010,797, US-A-6,321,621 and related patents There are various industrial rights applications and patents that protect these devices. Recent developments in the coaxial debonding sector have already been published and the PCT patent application PCT / IB2004 / 003020 will be published later.

  All of the described devices may be structurally similar or structurally different, with at least one insulating stripping blade (typically at least two or more insulating stripping blades). In accordance with the present invention, if the centering jaws are opposite, only one insulating strip blade could be provided) and at least one centering jaw or fixed jaw (usually at least two or more centering jaws or There is a fixed jaw, but according to the present invention, if it is opposite the insulating stripping blade, it would be possible to provide only one centering jaw or fixed jaw) in the immediate vicinity of the insulating stripping blade When viewed in the axial direction of the conductor from which insulation is peeled, the centering jaws or fixed jaws are adjacent as close as possible, It is understood to mean that the aligned Mari short distance away). Both the insulating stripping blade and the centering or fixed jaw can move independently of each other towards the main axis and from there at least some distance in the opening and closing direction, so that the insulating stripping blade and the centering or fixed jaw are Move in the direction.

  In any embodiment, the insulation stripping blade can rotate about the main axis with the force of a motor. Thus, the main axis is simultaneously the insulation peeling blade and the rotation axis for the centering jaw. (The design of the optical fiber 7045 is that only the blade rotates.)

  The depth of excavation of the insulation stripping blade is either electrical machine (which belongs to the applicant together with the patent family in other variants of the prior art, ie in the case of embodiments according to US-A 6,176,155) or electronically. (All cases of Applicants' above-mentioned device) adjustable.

  All the devices described from the prior art except MC252 and CS5300MX have one common point. Activation of the rotating blade and the centering jaw is caused by a lever pivotable about the pivot axis. These pivot axes are perpendicular to the main axis. Typically, a cone is provided that actuates the proximal end of the lever, while the distal end of the lever engages the blade directly or jointly. In the best known embodiment (starting with HC207 and MP257), this also applies to the centering jaw, i.e. they are also actuated by a two-armed lever. Due to the expected accuracy of the device, this requires a rather complex manufacturing both at the attachment and actuation of the lever and at the distal end transmitting the adjustment movement to the blade and centering jaw.

  In the known machines MC252 and CS5300MX, the rotating blade is operated by a cage that rotates with the blade about the main axis. The cage rotates relative to the blade as a result of the blade being fed. The rotation of the cage occurs via a grooved track. In these grooved tracks, linear movement is converted into rotational movement by a nail moving in the direction of the main axis. This step requires a rather complex production, especially because the accuracy of the device is expected.

  The present invention aims to improve the above-described device, so that the blade is more easily adapted to the operation of the blade as easily and as easily as the centering or fixed jaws do not have to rely on complex and expensive parts. Operates by way.

  In other words, the aim is to simplify the parts used in the working area of the blade and the centering or fixed jaw without adversely affecting the accuracy of the device.

  If each insulation stripping blade and each centering or fixed jaw associated therewith are driven by an electric machine or in the direction of opening and closing by a drive shaft extending in parallel with the drive shaft or at an acute angle with the drive shaft, and at least the mounting insulation stripping This objective is reached when the drive shaft is driven by a motor so that it can rotate with the insulation peeling blade with respect to the main axis.

  With the present invention, this goal is reached in a surprisingly simple manner. Instead of the disadvantageous lever arrangement as described above, the insulation stripping blade and the new shaft arrangement for the centering or fixed jaw provide a substantially simpler device that is easier to manufacture. Thus, for example, rotating parts can be manufactured more easily and cheaply than cutting parts in mass production. Of course, the shaft is mainly a rotating part. According to the criteria according to the invention, the insulation stripping device according to the invention is harder and therefore more precise than before, but the production cost is low. As the drive shaft rotates with the blade, the preferred insulation stripping blade in MC207 or FO7045 remains, and the above rotation may be required for high precision insulation stripping, especially in the case of coaxial or fiber optic cables. Are known.

  Next, in the case of a suitable insulation stripping device, both the drive shaft of the insulation stripping blade and the drive shaft of the centering or fixed jaw can be rotated with respect to the main axis. Thus, for example, the conventional HC207 or MP257 is manufactured with exactly the same function, but in the case of a new insulation peeling head, there is a manufacturing advantage. These known setting machines can thus be manufactured considerably cheaper. The entire head is expected to be made harder, which has a positive impact on the processing quality of the cable or wire from which the insulation is stripped.

  Insulative stripping heads of suitable size according to the invention are already on the market as spare parts or machine replacement heads. The patent claims are to be construed that such exchange heads are also within their scope of protection.

  As in the case of HC207 and MP257 or MP8015 described above, it is preferred that at least two insulation stripping blades and at least two centering jaws or fixed jaws are provided, in order to reach an excellent centering function, the centering jaws or fixed jaws Is preferably adjusted diagonally with each insulation peeling blade or one insulation peeling blade or centering jaw and fixed jaw (4) is adjusted diagonally with each insulation peeling blade or respective centering jaw and fixed jaw. .

  Thus, in accordance with the present invention, the insulation stripping blade can be associated with a direct opposing insulation stripping blade or a direct opposing centering jaw. However, the present invention is not limited to this, and other well-known contents and experiences can be used, for example, the centering jaw and the number of jaws of the insulating peeling blade are different.

  It may be advantageous if the number of centering jaws or insulation stripping blades is not equal if the same number of centering jaws are provided. Thus, for example, as in a setting according to US-A-5,010,797, three rotary insulation stripping blades could be fed to the side on which three centering jaws are arranged simultaneously according to the invention. In the case of the arrangement of the three insulating peeling blades, the opening surrounded by the insulating peeling blades approaches a triangle in which the cable cannot be pulled out in contrast to the arrangement having only two insulating peeling blades, for example.

  In particular, the operation of the new insulation stripping blade assumes that the insulation stripping blade or centering jaw or fixed jaw is guided by a linear guide and can be moved directly or indirectly, for example via gears, by means of a drive shaft coordinated with each. In contrast to the device in which the insulation stripping blade is thus firmly connected to the shaft and pivoted laterally towards the conductor, in this embodiment the blade is in spite of the shaft operation, for example in the well-known insulation stripping device Enters the conductor in a straight line as deemed effective.

  The design according to the invention assumes that, in the case of a drive shaft intended for an insulation stripping blade, a centering jaw or a fixed jaw parallel to the main axis, these blades and jaw can each be swiveled in a plane. Thus, the pivoting force of the blade or jaw is similar to that of the second embodiment (FIG. 3) of US-A-5,010,797, which will be described in more detail later. However, although there is a turning force, the drive shaft according to the present invention is particularly lacking for the embodiment supported at that time.

  Alternatively, the insulation stripping blade, centering jaw or fixed jaw can move or swivel in a plane that is rotationally symmetric with respect to the main axis, in the case of a drive shaft that makes an acute angle with the main axis.

  In the former case, since the cross section is perpendicular to the main axis only by this method, it is preferable that the plane is substantially perpendicular to the main axis.

  In the course of a fully automatic device solution, it is of course important that the drive shaft operates with a motor, in particular with electricity, air pressure or hydraulic pressure, and the operation of the motor can be regulated or controlled in particular electronically.

  Of course, in the case of the device according to the invention, it is advantageous if computer control is provided or pre-enterable control parameters (coaxial cables) of different depths and lengths for multilayer insulation stripping can be stored.

  Especially if the two corresponding drive shafts of the insulation stripping blade and the centering or fixed jaw are arranged rotationally symmetrically with respect to the main axis or are arranged coaxially with respect to their own drive shaft. Is supplied. In particular, the coaxial arrangement provides a very neat situation on the insulation stripping head, on which only a few parts are visible to the observer, hence chip removal and slug removal and insulation stripping blades. There is an advantageous space for holding.

  At the end away from the blade or centering jaw or fixed jaw, the drive method for rotational actuation of the drive shaft itself, which is preferred with respect to its own shaft, is in accordance with the invention on the one hand firmly connected to the drive shaft and on the other hand a cam In particular, the operation lever meshing with the operation cone or the like is located on the central operation axis coaxial with the main axis. The control lever is also designed as a rocker arm.

  If the operating cone for the insulation stripping blade and the operating cone for the centering or fixed jaw are arranged properly along the control axis, again a better integration is reached. At the same time or not, it is preferred that the operating cone is in the form of a rotating part that in turn leads to extreme economic production.

  According to the present invention, the two cones can be replaced in relation to each other, and the centering jaw operating cone is driven by a spring or brake from the operating cone of the insulating stripping blade. can do. This development initially ensures movement of the insulation stripping blade and centering jaws, partially independent of each other, and then allows both simple drives.

  Alternatively, it is preferable that the two operating cones can be actuated by a motor, ie independent of each other, by axial replacement of the operating shaft or at least by one operating rod or operating shaft inside the operating shaft.

  Regardless of the above-mentioned operation rod inside the operation shaft, the operation shaft has a central cable sensor that is coaxial with the main axis, so it is formed to be a depression and can be replaced along the main axis, It forms a length setting for the cable or conductor from which the insulation is stripped, while also forming a spring stop element for the insulation stripping process. In fact, cable sensors at HC207 and MP257 could also be used with replaceable insulation stripping heads.

  It would be advantageous if each insulation stripping blade was kept on a separate blade jaw so that the insulation stripping blades could be replaced more easily.

  The new blade jaws according to the invention have separate trapezoidal grooves for which the diagonal insulation stripping blades are fixed and released by the mounting wedge.

  If the insulation stripping blade is a tool of its own type, such as a circular saw type, a completely different type of insulation stripping device is obtained, and the drive elements for these tools are guided to the jaws of the blade. Such a driving tool is itself disclosed, for example, by ISIDA in machine MCS 102, but is not actually set. However, the driving tool combined with the new principle of the present invention required a new emphasis. In particular, the newly existing drive shaft is more suitable than the rocker arm that supports the drive shaft for previously used drive tools.

  If at least the centering jaw or the fixed jaw is completely or partially roughened at least in the face of the cable or optical fiber, a conductor or cable preferential guide from which the insulation is stripped is obtained. Roughening occurs by means well known per se, but also occurs automatically, for example, by appropriate manufacturing processes of these parts. Thus, these parts could be produced by the preferred roughening that occurs, for example, in water jet cutting, water jet interfaces.

  It is preferred that the connection between the insulating peeling blade or blade jaw or centering jaw or fixed jaw and the respective drive shaft is produced by caulking or pressing. However, this connection can also be produced by welding, soldering, threading or gluing within the scope of the present invention.

  According to other developments, other non-rotating clamping devices can be fed to the side of the insulation stripping blade on the opposite side of the sensor, and the drive shaft with the insulation stripping blade and the drive shaft with the centering or fixed jaws It can be displaced along the main axis associated with the clamping device to be controlled. Alternatively, of course, a clamping device can be substituted to control the removal of the slag.

  If the insulation stripping blade or blade jaw or centering jaw or fixed jaw is spring loaded in the open direction, a simple drive is obtained for them. As a result, the motor drive needs to operate accurately in a certain direction.

  Independently of the above, in connection therewith, the present invention relates to an insulation stripping device having an insulation stripping blade that pivots in the principal plane in the first plane, and in the principal plane in the second plane for the cable or conductor. A centering jaw that pivots away from it is positioned in the immediate vicinity of the insulation stripping blade. The novelty and inventiveness of this design compared to the design of FIGS. 8 and 9 of US-A-5,010,797 is that two jaw devices with initially swiveling jaws are provided in parallel with each other. The fact is that one (insulation stripping blade) is driven by the inside of a turn towards the side that is parallel to the other (centering jaw) and parallel to the other. The drive method is kept the same for both (insulation stripping blade and centering jaw) for both that are within the scope of the present invention.

  The design should be able to be protected independently, allowing a completely new concept for an insulation stripper that offers the advantages or solutions mentioned at the outset. However, the common basic concept of the two independent solutions provides uniformity in the sense of Article 82 EPC (European Patent Convention).

  An alternative new design emerges in the context of uniformity for the insulation stripping blade or centering jaw, as described for the drive shaft at an acute angle with the main axis. This is because they turn toward and away from the main axis of a surface that is rotationally symmetric with the main axis.

  The present invention with at least three insulation strippers and at least three centering jaws or fixed jaws, if they are supported independently of each other by a drive shaft, preferably a hollow shaft, but a wide range of slightly different protection fields Independently from the first two insulation stripping devices joined together by the general concept for insulation stripping devices according to the above, at least two drive shafts are arranged coaxially with each other. This coaxial mounting of the two drive shafts is a new invention for the insulation stripping device, and as a result, the above-mentioned positive effect (space) has been achieved and simple manufacturing has become possible. It is because is solved.

  It is particularly preferred, however, that it appears for the first time as a result of a new type of operation with the drive shaft according to the present invention, provided that the drive shaft is disconnected from the insulation peeling head housing and can move freely. Such blockage occurs most simply by a precise fit or guidance or by an O-ring or the like, ensuring that the tip does not pass behind the housing or into the bearing. This criterion makes the operation even less dirty than before.

  In an embodiment of the invention, the centering jaw or the fixed jaw is arranged away from the housing, preferably on the side of the insulation peeling blade between the insulation peeling blade and the clamping device.

  In another inventive concept unrelated to the above, connected by a common inventive concept, an insulating strip having an insulating stripping blade and a blade jaw pivoting along an arc away from and toward the main axis of the cable from which the insulation is stripped The device has a centering jaw at the same time, which becomes a spring-loaded lever with a pivot on the operating shaft of the insulation stripping blade. This design solves the problems mentioned at the outset and recognizes particularly good centering. This is because the blade is attached and thus exerts a force where it improves the accuracy of insulation stripping. This applies not only to a case having a non-rotating insulation peeling device, but also to a case having an insulation peeling device according to the present invention, and at least the jaws of the blade and the insulation peeling blade rotate with respect to the main axis.

  The invention will be further detailed with respect to the non-limiting embodiments illustrated in the drawings.

  Identical parts are provided with parts having the same reference numbers and the same function, but different designs have different indices with the same reference numbers. The drawings are described as a whole. Explicit references are made in the drawings and are described in connection with the drawings of US-A-5,361,384, the contents of which are incorporated by the present invention. Only the new insulation stripping head variants alongside the spindles 20a and 20b are described in the following description in order to relate to the economics of the process and not to overload this description. It is not described in the parts of the insulation stripping device that supports or incorporates the drive and does not incorporate the drive and control outside the insulation stripping head itself. This is because these parts are employed from any known insulation stripping device and are not a problem for those who use other parts of the well-known description of the insulation stripping device for a new insulation stripping head. As already mentioned, the new insulation stripping head can also be used as a spare part for existing insulation stripping devices, for example HC207 and MP207 and MP257, which have been produced earlier. In this respect, the parts used there for several years and known to the parties and their construction are also incorporated by reference according to the invention. The drawings of the above-mentioned US-A-5,361,384 provide information on these parts and structures by basic schemes.

  Different insulation stripping heads according to FIGS. 1a and 1b should be considered together for certain functions.

  For simplicity, they are both shown with the insulation stripping blades 3a and 3b in the plane 7 (common to this figure) relative to the main axis 1. According to an embodiment, the clamping device 15 is shown in FIG. 1 a because it can be replaced in connection with this plane 7. When the insulation peeling blade 3a is opened and the insulation peeling jaw 4a is opened, the cable 2 or the like is pushed into the space behind the insulation peeling blade 3a through the plane 7, whereas in the drawing according to FIG. Pull the cable 2 from the space behind the blade 3b and return it to the plane 7. If the insulation peeling blade 3b is closed with respect to the insulation peeling depth and the centering jaw 4b is also closed, the slag is removed (as shown in the figure). It has not been). The slag remains on the conductor such as the cable 2 if only downward or limited insulation peeling (with “window”) is set in the space behind the insulation peeling blade 3b.

  This form of insulation stripping with replaceable fastening device 15 is used according to the present invention, particularly in the case of insulation stripping devices, which can be used to perform other functions such as cables for transfer to other processing equipment. Formed as part of a larger automated device. However, in the case of a simple table surface apparatus, the insulation peeling apparatus is generally formed as before according to the present invention, and the whole insulation peeling head 21a or 21b having the main shaft 20a or 20b is connected to the main axis 1 respectively. Can be changed along the vertical direction.

  The main shaft 20a or 20b substantially corresponds to the main shaft already used in the cases of HC207, MP207 and MP257, so that the integration of the new insulation stripping head 21a or 21b is also used there as a spare part Is preferred. At the end closest to the device (proximal end), the main shafts 20a, 20b have gears 22 which in each case serve for the rotational drive of the insulation stripping heads 21a, 21b with respect to the respective main axis 1. The gear 22 is preferably driven by a toothed belt and an electric motor, which is not detailed here, but has already been realized in the known machines mentioned above.

  It is preferred that this device and each of the other devices mentioned later be controlled in a programmable manner by electronic or electromechanical controls 18.

  At the end portion (distal end) closest to the operator, the main shafts 20a and 20b serve as fixing portions 23a and 23b, respectively. These fixing portions 23a and 23b support the hollow drive shafts 6c (3) or 6d (2) at the distal ends where the insulation peeling blades 3a and 3b are assembled without rotation by the jaws 13a and 13b of the blades, respectively. .

  In the drive shafts 6c and 6d, the cams 8a and 8b are fixed to the drive shafts 6c and 6d without rotation, and the control movements produced by the operation spiral 5a (FIG. 4) or the operation cone 9a are controlled by the blade jaws 13a and 13b, Therefore, the insulating peeling blades 3a and 3b are converted into rotational or swiveling motions. The operation spiral 5a and the operation cone 9a are assembled by the related main shafts 20a and 20b along the corresponding main axis 1 and controlled so as to be movable in the vertical direction. Thus, the vertical movement performs the opening / closing operation of the insulating peeling blades 3a and 3b. The principle of the operating cone has already been realized in HC 207, MP 207 and MP 257, but wedges are supplied for operation which are harder to manufacture than the cone used here. The operating spirals 5a and 5b used according to the embodiment of FIG. 1a are novel and the longitudinal movement of the operating spirals 5a and 5b in any direction effective according to the present invention is achieved with the insulating stripping blade 3a and the centering. Each jaw 4a is forcibly closed or forcibly opened. In comparison, the design according to FIG. 1b requires one restoring spring (not shown) per drive shaft 16 to open the insulation peeling blade 3b. The same applies in principle to the fixed jaw.

  In FIGS. 1a and 1b, the drive shafts 6c1, 6d1 are shown as tubes in the bearing bush 24a. However, the latter (6d) can also be guided into the fixing part 19 without bearing bushes, as shown in FIG. If the bearing bushes 24a, 24b are manufactured from bearing bronze, in the case of excellent induction, only a slight resistance to the rotation of the drive shafts 6c1, 6d1 occurs. The design according to FIG. 2a shows an improved version which is managed by the fact that the bearing part 23b and the drive shaft 6d are properly formed without an additional bearing bush (24).

  The insulation peeling blades 3a, 3b and the jaws 13a, 13b of the blades have different designs. According to FIGS. 1a and 4, the blade jaw 13a is designed as a simple swivel lever, the insulation peeling blade 3a has a trapezoidal design, while the insulation peeling blade 3b is formed in a rectangle like a conventional insulation peeling blade, A trapezoidal groove 12 in the blade jaw 4b perpendicular to the main axis 1 can be replaced. In adjusting the insulation stripping blade 3b, optimization is performed by first adjusting the blade jaw 13b and then adjusting the insulation stripping blade 3b. Advantageously, this means that the quality of the blade itself may be lowered at the same time without changing the accuracy of the insulation debonding. The blade 3b may also have an oblique cutting edge. The oblique cutting edge has the advantage that the contact blade / cable moves during the cutting process. This may increase the service life of the blade.

  In comparison, the trapezoidal insulation stripping blade 3a is a simple, small leaf-like component that is cheap to manufacture due to its size and fits through the outer edge 25 into a diagonal recess 26 in the blade jaw. In light of a particularly preferred embodiment according to the invention, which can also be used independently of the invention, the fixing of the leaf-like insulating peeling blade 3a is effected by means of a screw 27 with a conical head or a hole 28 with a receiving cone. As the exit cone compensates somewhat in relation to the hole 28 or the axis of the screw 27, the insulation stripping blade 3a is pushed into the recess 26 by the outer edge 25 when the screw 27 is tightened. In this way, high accuracy is possible under conditions that require a particularly simple and quick blade change. If the insulating peeling blade 3a is accurately manufactured, no adjustment is required after the insulating peeling blade is changed.

  The driving and mounting of the centering jaws 4a and 4b are supplied in a manner similar to the driving of the mounting and insulation peeling blades 3a and 3b. The drive shafts 6a and 6b are mounted in the drive shafts 6c and 6d, respectively, bear the centering jaws 4a and 4b at the distal end, and have cams 8c and 8d nearby in cooperation with the operation spiral 5b and the operation cone 9b. .

  This “one-on-one” structure with very simple parts (tubes or shafts) results in a very stable and integrated design. The principle of this design also allows the provision of other insulation stripping blades or centering jaws to make different cuts at the same time at different axial positions of the cable 2 in certain circumstances. For this reason, only the drive shaft 6a or 6b needs to be made hollow and a comparable arrangement with 6a-6c, 6b-6d with corresponding tips, and a proximal structure would have to be provided. Within the scope of the present invention, such multi-blade designs are also protected.

  The centering jaws 4a, 4b have different designs. The jaw 4a is preferably in the form of a triangular pivoting lever with a slightly recessed centering edge 29a, while the centering edge 4b is a slightly angled lever with a straight centering edge 29b. Centering edges 29a and 29b can be roughened. Such roughening is made automatically, for example, due to the fact that the centering jaws are made by water jet cutting.

  The operating spirals 5a, 5b or operating cones 9a, 9b are moved by means of rods or tubes displaced by shafts guided inside the operating spirals 17a and 17b or the main shafts 20a, 20b, where they are driven by a drive known to the party. It emerges from the proximal end of the main shafts 20a, 20b to be actuated.

  When the operation spiral 17 or the rod is in a tube form, the cable contact sensor 11 (FIG. 2a) can also be arranged inside. In this respect, mention is made in particular of the publications or educational materials, ie which publications or educational materials are incorporated therein, from known insulation stripping devices in which the behavioral functions and modes of such cable contact sensors 11 are shown.

  The embodiment according to FIGS. 2 a and 2 b shows a version without the bearing bush 24. The shafts 6d1 and 6d2 are assembled to the fixing portion 23b that becomes long. The bearing portion may have a blind hole for weight reduction not shown in addition to the hole for the drive shaft 6 in order to contribute to the moment inside the insulation peeling device. In particular, it is preferably made of a light metal such as aluminum or an aluminum alloy. However, aside from the cable contact sensor 11, FIGS. 2a and 2b correspond to FIG. 1b.

  In order to protect the insulation peeling heads 21a, 21a1, 21b, 21b1, the insulation peeling head housing 19 (FIGS. 2a, 2b) is fixed with only a single screw parallel to the main axis, in particular by the first fixation according to the invention. Dismantling is easily possible because it is supplied to be supported on the parts 23a, 23b, 23a1, 23b1, possibly without eccentricity:

  As can be seen from FIG. 5, the distal end of the anchoring portion is provided with an annular groove 31 into which the O-ring 32 is inserted in the assembled state. The O-ring 32 has a size projected from the annular groove 31 in the inserted state. When the inserted O-ring 32 is pushed from the proximal end to the distal end, it serves as a stop for the tube insulation peel head housing 19 (FIGS. 2a, 2b). Since the annular groove 31 is perpendicular to the main axis 1, this stop—if the insulating stripping head housing 19 has a distal end edge 33 perpendicular to the outer surface—the optimum of the insulating stripping head housing 19 having the main axis 1 Provides a parallel and eccentricity arrangement. In this way, the O-ring 32 is a shield for the insulation peeling head housing and is stopped. In addition to simple manufacture, the main advantage is that the O-ring is easily removed and the insulation stripping head housing 19 is pushed in the terminal direction (blade direction) or removed in the downward direction. This makes the access to the cam / control lever particularly fast and easy.

  The housing 19 is fixed to the fixing portions 23a, 23b, 23a1, and 23b1 by fixing screws 34 so that the housing does not move in the proximal direction. This design of the insulation peel head housing and the fixing to the insulation peel heads 21a, 21b, 21a1, 21b1 is novel, talented, protected and independent of other functions of this application Because of its simplicity, it can be used with other insulation strippers.

  In order to strip the fine cable (MC or MX head) insulation, in these cases other versions which are preferred embodiments can be selected, in which embodiment the insulation stripping blade (3) or the centering and fixed jaws The drive shafts (4) are guided by the linear guides and coordinated with them in the respective case are moved directly or indirectly, for example by gears.

  The present invention also includes improvements to the rotating centering jaws, which are preferably used with a new stripping head, but are independent of it. Each of the V-shaped centering jaws is attached to one rocker by the drive shaft 6b. These rotate with the peeling head. The two V-shaped centering jaws have the same shape and are placed diagonally to each other at an angle of approximately 180 °.

  The V-shaped centering jaw 4c shows two surfaces 29c, 29d facing inward (shown as 29c and 29d in FIGS. 6 and 7) in the tangential plane of the cable. Since the two centering jaws 4c have been set up so far in synchronism with the movement of the blade 3c, the cable (2 in FIG. 1) is centered by the four faces 29c, 29d before cutting begins.

  The control of the centering jaw 4c is performed in the same way as that of the centering jaws 4a to 4b in other versions of the invention. The closing movement of the V-shaped centering jaw 4c continues until the centering jaw 4c rests on the cable, and the spring action of the spring between the cone 9a and the cone 9b is no longer sufficient to further close the centering jaw. The cable cannot reopen the V-shaped centering jaw 4c for automatic locking or in-situ automatic locking.

  The V-shaped jaw 4c has the goal of limiting the degree of free conversion radially with the cable shaft if possible. The cable can be prevented from moving further radially with respect to the cable axis. Avoid momentary movement on the cable that will cause the cable to twist. Furthermore, permanent distortion of the cable surface or other losses can be avoided. This is achieved by an improvement in which the centering surfaces (shown as 29c and 29d in FIGS. 6 and 7) run as smoothly as possible or show an anti-friction coating. The twisting force of the cable is not necessary enough to center the cable best. Too long surface pressure should not occur. If the optimal relationship between the size of the centering surfaces depends on the characteristics of the cable, a spring between the two cones 9 or operating spirals 5 and the friction conditions (eg surface treatment of the back cone) must be selected.

  The V-shaped centering jaw 4c is arranged to be as close as possible to the cut surface. The centering surface 29c immediately adjacent to the blade 3c should preferably be parallel to the aligned blade edge 3c. In this way, the slack cable that is bent in the cutting direction of common sense movement will not move locally. If the approaching centering surface 29c (as well as the plane 29d) is positioned perpendicular to the blade edge (eg, the red surface will be immediately adjacent to the blade), the cable will have local cross-sectional movement. As a result, the transfer cross section by the two blades 3c may be reached. In these cases, double cuts may occur, but this should be avoided. This effect appears with finer cables than thick cables. However, a hard cable is also guided by the arrangement of the centering surface shown in FIG. The closing movements of the two V-shaped centering jaws 4c are connected to each other. When contrasted via training of the connection of two centering jaws (surface 29c is on a different radial surface than surface 29d), the centering jaws are in an axial direction—they surround the cable As soon as it supports itself from each other, the cable improves the quality for centering.
