Description

Magazine for processing wire end sleeves and hand tools for crimping wire end sleeves

The invention relates to a magazine for processing wire end sleeves, which are connected to one another via connecting webs to form a wire end sleeve strip, with a housing, the housing having at least one housing base and an insertion opening for the insertion of the wire end sleeve strip.

Furthermore, the invention relates to a hand tool for crimping wire end sleeves with a stripped conductor end or with the strands of a conductor, with a pliers-like handle, with at least two press jaws which can be brought together by operating the handle and form a sink in which the wire end sleeve can be positioned and be stored with a magazine in the ferrules, the ferrules being fed from the magazine to the die. The pressing of wire end sleeves with a stripped conductor end or with the strands of a conductor is also known as crimping in the prior art. When crimping, two components are connected to one another by plastic deformation, so that there is a homogeneous, difficult-to-break connection between the conductor and the ferrule. Crimping is used as an alternative to soldering or welding when making electrical connections. With the help of a hand tool or crimping pliers, the wires of a cable are positively connected to a wire end sleeve. Relatively high forces have to be applied. In most cases, several wire end ferrules should be crimped one after the other with the appropriate conductors. In order to save as much time as possible, there are crimping tools with a storage magazine in which wire end sleeves are stored. After crimping a wire end ferrule, the next wire end ferrule can be inserted into the tool manually or automatically.

EP 2 182 595 A2 shows, for example, a removable magazine for hand-operated crimping pliers. The magazine has a cylindrical base body in which a plurality of channels distributed over the circumference are formed, into each of which individual housings which serve to accommodate individual electrical contacts are inserted. The electrical contacts are placed individually in the magazine. DE 42 41 224 CI discloses a crimping tool with a zylinderför shaped magazine for receiving a wire end ferrule strip. The magazine is arranged at a distance from the actual crimping station so that the beginning of the ferrule strip is introduced from the magazine through an opening in the housing of the crimping tool into the area of a transport device. The transport device has as an essential component a transport wheel which has recesses evenly distributed over its circumference and is rotatable about an axis. A single ferrule is separated from the strip during the actual crimping process. The connecting web between the foremost wire end ferrule and the following wire end ferrule is torn off by a movable crimping jaw pushing the foremost wire end ferrule radially outwards, i.e. the normal radius of the depressions is exceeded, so that the front wire end ferrule is displaced radially outward. The handling of the aforementioned magazines and hand tools is disadvantageous. It is sometimes difficult to insert the individual ferrules into the magazine. When inserting strands into wire end sleeves that are connected to one another, it can happen that the strands are bent over and not inserted into the wire end sleeve, since the immobility of the hand tool makes it difficult to insert the conductor. This can result in faulty crimp connections, which can lead to damage in devices in which the conductor with the ferrule is installed.

The present invention is therefore based on the object of specifying a magazine for processing wire end sleeves and a hand tool with a corresponding magazine that ensure easier handling and an improvement in process reliability.

According to a first teaching, the invention relates to a magazine in which the previously derived object is achieved. The magazine according to the invention is initially and essentially characterized in that a transport wheel rotatably mounted about an axis of rotation is arranged in the housing, that the transport wheel has several depressions for receiving individual wire end sleeves of a wire end ferrule strip, two adjacent depressions each by an edge are separated from each other so that by turning the transport wheel, the wire end sleeves of the wire end sleeve strip are moved one after the other into an assembly position. can be brought, in which the connecting web between two adjacent wire end sleeves is at least partially severed from the edge of the corresponding recess. The depressions of the transport wheel are distributed over the circumference of the transport wheel, so that the depressions are designed in the manner of a shovel and the transport wheel is designed accordingly as a paddle wheel. The wells are arranged in the circumferential direction at regular intervals zuei nander. The ferrules can each be arranged in the recesses. The connecting webs with which the ferrules are connected are arranged directly on the edges of the wells. The edges of the depressions or the edges of the transport wheel also serve as cutting blades, which are moved together with a housing wall or a component mounted in the housing during the cutting process towards one another. In this way, the transport wheel can be rotated in the housing, for example, until one of the edges approaches the component or the housing wall at a desired point in the housing.

A further rotation of the transport wheel approaches the edge of the recess and thus also the connecting web located on the edge of the housing inner wall or the component in such a way that the distance between the edge and the housing wall is minimal. A further rotation causes the flexible connecting web to be compressed and ultimately severed so that a wire end ferrule is separated from the wire end ferrules connected to form a strip.

Preferably, the wire end ferrule is severed in the vicinity of the mounting position of the wire end ferrules. This increases process reliability, since the wire end sleeves remain connected to a strip until the time of assembly or the insertion of a conductor into the wire end sleeve and no individual wire end sleeves can be incorrectly positioned in the magazine.

For a simplified further processing of the isolated wire end ferrules it is provided in an advantageous embodiment of the invention that the housing has at least one housing bottom that an opening is formed in the housing bottom, with a wire end ferrule in the assembly position being arranged in the immediate vicinity of the opening. After isolating and processing a ferrule, the ferrule can be removed from the magazine through the opening. The opening can be funnel-shaped be well designed. By turning the transport wheel further, the next ferrule is separated from the ferrule strip and can be processed. The rotation can be done manually or automatically with a suitable gear and drive. The housing of the magazine can have any geometry. The housing is preferably designed in a cylindrical shape. But it can also have a different rotationally symmetrical shape. It is also conceivable that the housing is designed in the manner of a spiral or spiral.

In order to achieve a more targeted separation of the individual ferrules, an advantageous embodiment of the invention provides that the transport wheel is surrounded by a housing wall which has at least one spiral-shaped section in which the distance between the edges of the recesses and the housing wall in the direction of the opening decreases in the radial direction. The distance between the edges of the recess and the housing wall consequently decreases steadily in the circumferential direction of the transport wheel from that in the direction of the opening. In this way, a respective edge of the paddle wheel approaches the housing wall as the rotation of the paddle wheel progresses until the distance is minimal. When wire end sleeves are used, the connecting web is still located between two wire end sleeves on the edge of the depression, which separates the two adjacent depressions. By further sewing the edge onto the housing wall, the connecting web is pressed against the edge of the recess of the transport wheel. Since the distance decreases steadily with a further rotation of the transport wheel, due to the spiral shape of the section of the housing wall, the connec tion web is severed at the minimum distance between the edge of the recess and the housing wall. The severing of the connecting bars takes place in the radial direction, starting from the center of the trans port wheel. In order to further improve the handling of the magazine, in particular with regard to the at least partial severing of the connecting webs, it is provided in an advantageous embodiment of the magazine according to the invention that the housing has a housing above the transport wheel, which together with the housing wall and the Transport wheel forms a guide channel for the ferrule strip that the Housing upper wall has a slope so that the height of the guide channel decreases in the direction of the opening. The distance between the depressions Ver and the upper housing wall consequently decreases steadily in the circumferential direction of the transport wheel in the direction of the opening. In this way, starting from the insertion opening, the ferrules are pushed deeper into the recesses as the rotation of the transport wheel progresses, since the distance to the upper wall of the housing continues to decrease.

The depressions can be designed so that they receive the Aderendhül sen positively without play and are designed overall deeper than the longitudinal extension of the wire end sleeves, so that they can be introduced further into the depressions with little resistance. If, as the transport wheel rotates, the distance between the edges of the recesses and the housing wall or a component mounted in the housing is reduced, the connecting web between the ferrules is not evenly severed in the radial direction, i.e. at every point at the same time. Rather, the connecting web is axially at least partially severed due to the simultaneous axial movement of the wire end sleeves. During the partial severing, the wire end ferrules are moved along a curved path and, at least temporarily, additionally displaced in the direction of rotation by the incline of the upper wall of the housing. In this way, the connecting webs are axially cut through, that is to say continuously along the length of the wire end sleeves.

For the simple introduction of a conductor or the strands of a conductor into the end sleeve, in one embodiment of the invention, a funnel-shaped conductor inlet opening is formed in the upper wall of the housing, the conductor inlet opening and the opening in the housing base are in a line so that they have a common longitudinal axis . The longitudinal axis runs parallel to the axis of rotation of the transport wheel before preferably. However, it is also conceivable that the common longitudinal axis of the conductor inlet opening and the opening runs obliquely with respect to the axis of rotation of the transport wheel or is arranged at an angle to the axis of rotation other than 0 degrees. In this way it is possible to introduce a conductor at an angle to the housing. A conductor or the strands of a conductor can preferably also be introduced into the conductor inlet opening parallel to the axis of rotation of the transport wheel. When the wire end ferrule is in the assembly position, it is located between the conductor inlet opening and the opening. The wire end ferrule is in the assembly sition arranged in its longitudinal extension on the common longitudinal axis of the conductor insertion opening and the opening. The conductor insertion opening initially has a larger cross section in the insertion direction, which is further reduced in the insertion direction, so that an inserted conductor is automatically positioned. The conductor is inserted through the conductor insertion opening into the end sleeve, which is in the assembly position. To improve positioning, the funnel-shaped recess can be bordered by two funnel halves. When the strands are inserted, the funnel halves rest against one another and thus offer precise guidance of the strands of the conductor. When the conductor is inserted, the funnel halves are pressed apart by the wire insulation and ultimately by the wire end sleeves, so that they have a sufficiently large distance from one another to remove the wire end sleeve. The opening through which the ferrule can at least partially be guided out of the housing can also be funnel-shaped and / or surrounded by two separate funnel halves so that the ferrule is positioned accordingly. By means of an appropriately selected diameter of the opening, the insulating collar of the end sleeve remains in the magazine, since it has a larger diameter than the opening. It is also conceivable that a stop is formed at the opening, by means of which a complete lead out of the wire end sleeve is blocked from the housing, so that only part of the wire end sleeve is passed out of the housing for pressing and the insulating collar in the wire end sleeve remains in the magazine.

For improved positioning of the ferrule within the housing, a preferred embodiment of the magazine according to the invention provides that the distance between the housing wall and the opposite edge of the recess, which is arranged in the area of the opening, is dimensioned such that the connecting web has been severed by more than 60%, in particular more than 80%. In the assembly position and before inserting a conductor, the connecting web is consequently not completely severed dig. After a conductor has been inserted into the end sleeve, which is in the assembly position, the connecting web between the end sleeve in the assembly position and the other end sleeves is completely separated. In the case of an axial cut, part of the connecting web is not severed in the axial direction. The introduction of the conductor, preferably parallel to the axis of rotation of the transport wheel, ensures that the connecting web is completely severed. The connecting bridge is When the conductor is imported, it is already weakened to such an extent that the import is sufficient to tear the ferrule from the rest of the ferrule strip. This applies analogously to a radial cut or the radial separation of the connecting web. In the assembly position of the wire end sleeve, the connecting web is pressed against the edge of the recess and is already weakened to such an extent that the insertion of the conductor is sufficient to completely separate the wire end sleeve from the strip. It is conceivable that the ferrule is pressed even further into the recess when the conductor is inserted through the conductor opening, so that a complete separation of the ferrule from the rest of the strip is possible.

The opening is in line with the conductor entry opening. In this way, a conductor can be inserted through the conductor insertion opening into a wire end sleeve in the assembly position. If the conductor is moved further into the conductor insertion opening, the ferrule detaches from the rest of the ferrule strip and the ferrule is at least partially conveyed out of the housing together with the conductor through the opening for further processing. Due to the funnel-shaped conductor insertion opening, the conductor is ideally aligned with the ferrule. The opening under half of the ferrule allows ideal positioning of the ferrule with inserted conductor for further processing.

The accuracy of the positioning of the ferrule can be further improved in a further embodiment of the magazine according to the invention. For this purpose, it is provided that a positioning device is arranged between the transport wheel and the housing, which causes the transport wheel to rotate in steps. The positioning device gives the user a sense of whether the transport wheel is positioned in such a way that at least one ferrule is in the assembly position. The positioning device can provide haptic feedback, so that the user is informed when the transport wheel is turned that the assembly position has been reached. Visual or acoustic signals from the positioning device would also be conceivable. A preferred option for determining the position is a latching mechanism so that the transport wheel latches in the assembly position. In this way, the transport wheel is initially locked in the assembly position and the ferrule is ideally aligned with the conductor insertion opening and thus also with a correspondingly inserted conductor. In a preferred embodiment of the magazine according to the invention, it is provided that the positioning device is implemented by a spring-loaded ball catch. The ball catch is characterized in that a ball or hemisphere or a similarly spherical object acted on by a spring force serves as the catch. The resilient locking lug engages in corresponding locking recesses in the transport wheel. For this purpose, a latching recess can be provided on the transport wheel in the area of each recess, since each recess can be brought into the assembly position of the wire end sleeves due to the rotation of the transport wheel. The ball detent is easy to release due to the rounded detent, without the detent mechanism and the corresponding components being subjected to excessive wear. Nevertheless, the latching function is strong enough that the user is given haptic feedback that the assembly position has been reached. In order to further simplify the handling of the magazine according to the invention, one embodiment of the invention provides that the housing is at least partially transparent so that it can be seen from the outside how many wire end sleeves are arranged in the housing. The housing can be designed to be transparent, in particular in the area of the upper housing wall, which is arranged parallel to the transport wheel, so that the entire transport wheel and the depressions can be seen. This means that the user can easily see how many ferrules are still in the housing. A transparency of the housing in the area of the side walls or the lateral surface of a, for example, cylindrical housing would also be conceivable, so that a view of the circumferential side of the transport wheel is possible. Correspondingly, it is also possible to identify the end sleeves in the depressions in order to insert further end sleeve strips through the insertion opening into the magazine in good time before consumption. The rotation of the transport wheel can be simplified by providing a feed element in one embodiment of the magazine according to the invention which is connected to the transport wheel such that rotation of the advancing element causes rotation of the transport wheel. The front thrust element can be arranged outside of the housing so that it is easily accessible for the user. The feed element can, for example, have a wheel shape. The feed element can, similar to the Transport wheel, be provided with recesses at the same distance. In this way, the feed element is on the one hand more grippy, so that a rotation is easier to carry out, on the other hand, the user can orient himself on the depressions and estimate roughly how far the feed element has to be rotated so that the next assembly position is reached. For easier operation, the feed element can extend beyond the housing so that it is easy to reach with the fingers. The feed element does not have to be configured in the shape of a wheel. It can have any shape. The feed element is preferably arranged parallel to the transport wheel on the same axis of rotation, so that a direct translation to the transport wheel can be implemented. However, it is also conceivable that the forward thrust element is arranged offset perpendicular or parallel to the axis of rotation and is connected to the transport wheel via a gear.

According to a second teaching, the invention relates to a hand tool for crimping wire end sleeves with a stripped conductor end or with the strands of a conductor with a magazine for wire end sleeves, in which the previously derived object is achieved. The hand tool according to the invention is initially and essentially characterized in that the magazine is designed according to the invention. The statements relating to the magazine according to the invention apply accordingly to the hand tool according to the invention with an attached magazine.

With the hand tool it is possible to connect the wire end sleeve with the conductor or with the strands of a conductor in a form-fitting manner. A joining process, crimping, is used here. The wire end sleeve with the inserted conductor is placed in the die and pressed together via the pressing jaws in such a way that the wire end sleeve and the part of the conductor located in the Aderendhül se undergo a plastic deformation. In order to increase the force that can be applied by the user, the hand tool can have a toggle lever, since the transmission ratio between the force applied to the resulting force or from the primary stroke to the secondary stroke shifts continuously during the movement and thus initially higher speeds of the press jaws with lower force and in the decisive area a low speed can be achieved with a high force. Through the magazine connected to the hand tool, wire end sleeves, into which a conductor is already inserted in the advantageous manner mentioned above, can be fed to the die of the hand tool. The end sleeve can then be positioned directly in the die of the hand tool via the opening in the housing bottom of the magazine. The opening of the magazine is arranged directly above the die of the hand tool. A wire end ferrule that is in the assembly position can thus receive a conductor through the conductor inlet opening. If the conductor is inserted further into the ferrule, it detaches from the ferrule strip and is brought further through the opening directly into the die of the hand tool. The wire end ferrule is consequently, just like an inserted conductor, preferably inserted into the die of the hand tool parallel to the axis of rotation of the transport wheel.

Diversion means are provided for easy operability. The diversion means interact with the pliers-like handle and the pressing jaws in such a way that pressing at least one wire end sleeve with a stripped conductor can be carried out by operating the handle by hand. In this way, the user can crimp the ferrules with a conductor with as little effort as possible by simply operating the handle manually.

In an advantageous embodiment of the hand tool according to the invention it is provided that the magazine is detachably connected to the hand tool, in particular by a latching connection. The assembly of the magazine interest on the hand tool can be done, for example, by a rotary movement, similar to a bayonet lock, or by attaching it. The exact positioning of the magazine is done using pins or other elevations that are formed on the magazine and engage in corresponding recesses. The pins or elevations can also be formed on the frame of the hand tool and the corresponding recesses can accordingly be formed on the magazine. A close tolerance between the funnel-shaped opening on the housing bottom of the magazine and the center of the dies can thus be achieved. The latching can also be achieved, for example, by bent holding elements that engage behind the hand tool on the opposite side on which the magazine is attached. The positioning of the magazine prevents the Magazine thus excluded, although the magazine can be attached to the hand tool in a simple manner.

In order to increase the quality of the crimping of the ferrule, more than two pressing jaws are provided in an advantageous embodiment of the hand tool according to the invention, so that symmetrical crimping takes place between the ferrule and the stripped conductor end or with the strands of the conductor. The pressing jaws are then not only moved towards one another from two sides, but also moved towards one another from several directions in such a way that a symmetrical cross-section is created between the pressing jaws, i.e. that a symmetrical die is created. One advantage of using more than two pressing jaws is that the geometry of the die remains the same or very similar for a large cross-sectional area. The pressing jaws close in the manner of a diaphragm, as a result of which the geometry of the cross section of the die does not change noticeably when closing, since the pressing jaws are moved evenly towards one another.

For this purpose, in an advantageous embodiment of the invention, it is provided that the pressing jaws are arranged in such a way that a square pressing takes place. In an alternative embodiment of the invention, it is provided that the pressing jaws are arranged in such a way that hexagonal pressing takes place.

In detail, there are a number of possibilities for designing and developing the magazine according to the invention and the hand tool according to the invention. For this purpose, reference is made to the claims subordinate to claims 1 and 10 as well as to the following description of a preferred exemplary embodiment in conjunction with the drawing.

Fig. 1 shows a magazine 1 for processing arranged in the magazine 1 wire end sleeves 2, which fen 4 are connected to each other via connecting webs 3 to a Aderendhülsenstrei. The magazine 1 comprises a cylindrical housing 5 with a housing base 6 and an insertion opening 7 for the ferrule strip 4. A transport wheel 9 rotatably mounted about an axis of rotation 8 is arranged in the housing 5. In the magazine 1, the ferrules 2 are separated.

The separation is carried out as follows: The transport wheel 9 has recesses 10 in which the wire end sleeves 2 are arranged. The connecting webs 3 of the ferrule strip 4 lie on the edges 11 of the depressions 10. The transport wheel 9 is designed in the manner of a paddle wheel, so that the wire end sleeves 2 are guided in a circle when the transport wheel 9 rotates, with a wire end sleeve 2 in a Mounting position can be brought, in which it is arranged over an opening 12 in the housing base. A housing wall 13 of the housing 5 encloses the trans port wheel 9 on the circumference. The housing wall 13 has a spiral section 14. This means that the distance between the edges 11 of the recesses 10 and the housing wall 13 decreases in the circumferential direction of the transport wheel 9 in the direction of the opening 12, starting from the insertion opening 7. This means that the connecting webs 3 of the end sleeve strip 4 are pressed against the respective edge 11 of the recess 10. The further that Transport wheel 9 is rotated, the smaller the distance between the edge 11 and the housing wall 13, so that from a certain point the connecting web 3 can no longer withstand the pressure and the corresponding de ferrule 2 is separated from the ferrule strip 4. In Fig. 1 it can be seen that a housing outer wall 15 is arranged around the housing wall 13, through which the insertion opening 7 is enlarged by a circumferential length. In this way, longer wire end sleeves strips 4 can also be inserted into the magazine 1, even if not all the wire end sleeves 2 are arranged in the depressions 10 of the transport wheel 9 at the same time. It is also conceivable that several shorter ferrule strips 4 are arranged in the elongated insertion opening 7. These would then have to be moved manually into the engagement of the transport wheel 9 by being pushed further.

In addition, fastening elements 16 are arranged on the housing 5, with which the magazine 1 can be fastened to a hand tool (shown in FIGS. 8-11). A housing cover, not shown here, can be attached to the housing 5 by means of closure elements 17. The locking elements 17 or the lock together with the lid works on the principle of a bayonet lock. The cover is rotated relative to the housing 5. On the cover, latching hooks corresponding to the closure elements 17 are formed which engage in the closure elements 17 so that the cover can no longer be lifted off.

Fig. 2 shows part of a further exemplary embodiment of a magazine interest 1, in which an upper housing wall 18 is shown. The upper housing wall 18, together with the transport wheel 9 and the housing wall 13, delimits a guide channel 19 in which the wire end sleeves 2 are guided. The guide channel 19 has a slope 20 on the housing upper wall 18. This means that the distance between the transport wheel 9 and the upper housing wall 18 decreases in the direction of the opening 12 in the circumferential direction. For the practical application of the magazine 1, this means that the Aderendhül sen 2 are pressed steadily deeper into the recesses 10 through the bevel 20 when the transport wheel 9 is rotated starting from the Einführöff opening 7. At the same time, the edges 11 of the depressions 10 are guided closer to the housing wall 13 by the spiral section 14 of the housing wall 13. The connecting webs 3 of the ferrule strip 4 are consequently not only severed radially, but rather from bottom to top, ie axially and parallel to the axis of rotation 8 of the transport wheel 9.

The connecting webs 3 of the ferrule strips 4 are preferably not completely severed. A small remainder of the connecting webs 3 remains when the ferrule 2 is in the mounting position. In this way, the wire end sleeve 2 cannot be moved unintentionally in the housing 5. Only when a conductor, not shown here, is inserted with its isolated end through a Lleiterinführöffhung 21 in the ferrule 2 in the assembly position, the force exerted on the ferrule 2 when it is imported is sufficient to completely sever the connection.

The mounting position can easily be determined with the aid of a positioning device 22. This is a spring-loaded ball catch inside the housing 5. When the transport wheel 9 is rotated by a user from the outside via a feed element 23 in the form of a feed wheel, catch recesses 24 are made in the axis of the transport wheel 9 are moved via a ball acted upon by a spring force. In this case, the ball functions as a locking lug to the corresponding locking recesses 24, so that every time the ball is pressed into a locking recess 24 due to the spring force, the easily detachable locking connection signals to the user that the assembly position of another wire end sleeve 2 has been reached is.

FIG. 3 shows the exemplary embodiment according to FIG. 2 in a side view without wire end sleeves 2. This clearly shows the guide channel 19, which loses height over the circumference due to the incline 20. The wire end sleeves 2 are pushed further and further into the Vertie fungen 10 by the constant slope 20 and at the same time partially separated axially by the edges 11 of the wells 10. Fig. 4 shows part of a magazine 1, again without ferrules 2. It is recognizable the opening 12 in the housing base 6. The opening 12 is below the mounting position of a ferrule 2. If a ferrule 2 is arranged in the mounting position, a conductor can be inserted with its stripped end into the end sleeve 2 through the conductor insertion opening 21. By pressing down the conductor further, the connection fertilize between the ferrule 2 and the ferrule strip 4 completely severed. The ferrule 2 can then be passed through the opening 12 together with the Lei ter and then processed further who the. After processing, the crimped ferrule 2 can be removed together with the conductor from the magazine 1 and the transport wheel 9 rotated until the mounting position of the next ferrule 2 is enough.

FIG. 5 shows a magazine 1 with a feed element 23 in the form of a feed wheel which is arranged above the housing 5. For better handling, the feed element 23 is designed around the circumference in the form of a gear. This makes it easier to grip for a user and makes it easier to turn. In addition, it protrudes laterally beyond the housing cover in order to be more easily accessible to the user's fingers. The feed element 23 has a plurality of circular recesses 25 since it is rotatable together with the transport wheel 9 and thus relative to the housing 5. The circular recesses 25 are consequently positioned over the wire end sleeves 2, so that each time the transport wheel 7 is rotated into the assembly position of a wire end sleeve 2, a circular recess 25 is arranged over the conductor insertion opening 21 to enable a conductor to be inserted into the wire end sleeve 2 to enable the mounting position.

6 shows a magazine 1 with the upper housing wall 18 in which a conductor insertion opening 21 is formed. The feed element 23 is arranged on the housing bottom 6 and can only be reached from one side of the housing 5. The feed element 23 is not centered on the axis of rotation 8 of the transport wheel 9, but is arranged offset from it.

FIG. 7 shows the arrangement of the advance element 23 according to FIG. 6, together with the transport wheel. The feed element 23 is connected to the transport wheel 9 via a gear 26, so that the feed element 23 can be arranged offset from the transport wheel 9. Due to the design of the transmission 26, a rotation of the feed element 23 leads to a counter-rotation of the transport wheel 9, which depending on the arrangement of the Ma magazine 1 on a hand tool can be advantageous for the operation. Other types of gearing for a simultaneous rotation of the transport wheel 9 when the feed element 23 is rotated are, however, also easily conceivable for corresponding applications. 8 and 9 show a hand tool 27 for pressing wire end sleeves 2 or, more precisely, for crimping wire end sleeves 2 with stripped conductor ends or with the strands of a conductor in different views. The hand tool 27 has a pliers-like handle 28, which is intended to move several press jaws, not shown here, to one another. The pressing jaws form a die into which the ferrule 2 is inserted and can be pressed. A magazine 1 for processing wire ferrules 2 is attached to the hand tool 27. The magazine 1 is arranged in such a way that the opening 12 of the magazine is positioned in such a way that passing a ferrule 2 with an inserted conductor through the opening 12 from at least partially out of the magazine 1 results in the ferrule 2 automatically entering the die is inserted. The opening 12 is consequently arranged directly above the die. The wire end ferrules 2 are introduced into the magazine 1 in connected wire end ferrule strips 4 and separated within the magazine 1. Through the Lleiterin guide opening 21, a conductor can be inserted into a ferrule 2, which is in the Mon day position. If the conductor is pushed further into the conductor insertion opening 21, the conductor, together with the end sleeve 2, is passed through the opening 12 of the magazine 1 directly into the die of the hand tool 27 and ideally positioned. With the help of the handicraft tool 27, a crimp connection between the conductor end and a wire end sleeve 2 can then be made. After the crimping process, the conductor is pulled out of the magazine 1 together with the ferrule 2. The feed element 23 can then be rotated further so that another ferrule 2 is brought into the assembly position and the next crimping process can be started.

FIGS. 10 and 11 show a hand tool 27 with a handle 28 in two different views. A magazine 1 for processing wire end sleeves 2 according to FIG. 5 is arranged on the hand tool 27. The magazine 1 has a feed element 23 which can be rotated in the same axis of rotation 8 as the transport wheel 9 within the magazine 1. The feed element 23 is arranged on the outside of the housing 5 of the magazine 1 so that it is accessible to a user is easily accessible. Due to the position of the advancing element 23, the advancing element 23 has a plurality of circular recesses 25. At least one of the circular recesses 25 is located exactly above a mounting position of the wire end sleeves 2 within the magazine 1. Since the advance element 23 relative to the housing 5 is rotatable, but rotates simultaneously with the transport wheel 9 within the housing 5, the circular recesses 25 always remain above the same recess 10 of the transport wheel 9. The function of the hand tool 27 is otherwise analogous to that in FIGS. 8 and 9 described hand tool 27.
