DETAILED DESCRIPTION OF THE INVENTION

[0043] FIG. 1 shows a magazine 1 for processing wire terminations 2 that are arranged in the magazine 1, which wire terminations are connected to one another via connecting bridges 3 to form a wire termination strip 4. The magazine 1 comprises a cylindrical housing 5 with a housing base 6 and a feed opening 7 for the wire termination strip 4. A transport wheel 9 that is mounted to rotate around an axis of rotation 8 is arranged in the housing 5. The wire terminations 2 are separated in the magazine 1.

[0044] The separation is performed as follows: The transport wheel 9 has recesses 10, in which the wire terminations 2 are arranged. The connecting bridges 3 of the wire termination strip 4, in this case, lie on the edges 11 of the recesses 10. The transport wheel 9 is configured like an impeller, so that when the transport wheel 9 is turned, the wire terminations 2 are guided into the circuit, wherein a wire termination 2 can be brought into an assembly position, in which it is arranged in the housing base via an opening 12. A housing wall 13 of the housing 5 encloses the transport wheel 9 on the peripheral side. 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 starting from the feed opening 7 in the peripheral direction of the transport wheel 9 decreases in the direction toward the opening 12. This means that the connecting bridges 3 of the wire termination strip 4 are pressed against the respective edge 11 of the recess 10. The further the transport wheel 9 is rotated, the smaller the distance between the edge 11 and the housing wall 13, so that starting from a certain point, the connecting bridge 3 can no longer withstand the pressure, and the corresponding wire termination 2 is separated from the wire termination strip 4.

[0045] FIG. 1 shows that an outer wall 15 of the housing is arranged around the housing wall 13, through which outer wall the feed opening 7 is enlarged by one peripheral length. In this way, longer wire termination strips 4 can also be introduced into the magazine 1, even when not all wire terminations 2 are arranged in the recesses 10 of the transport wheel 9 at the same time. It is also conceivable that multiple shorter wire termination strips 4 are arranged in the extended feed opening 7. The latter must then be moved manually, however, by further insertion into the engagement of the transport wheel 9.

[0046] In addition, fastening elements 16, with which the magazine 1 can be fastened to a hand tool (depicted in FIGS. 8-11), are arranged on the housing 5. A housing cover, not shown, can be fastened to the housing 5 by means of closing elements 17. The closing elements 17 or the closure together with the cover work according to the principle of a bayonet closure. The cover is rotated relative to the housing 5. Latching hooks corresponding to the closing elements 17 are made on the cover, which hooks engage in the closing elements 17, so that the cover can no longer be raised.

[0047] FIG. 2 shows a part of another embodiment of a magazine 1, in which an upper wall 18 of the housing is depicted. The upper wall 18 of the housing, together with the transport wheel 9 and the housing wall 13, bounds a guide channel 19, into which the wire terminations 2 are fed. The guide channel 19 has an incline 20 on the upper wall 18 of the housing. This means that the distance between the transport wheel 9 and the upper wall 18 of the housing in the direction toward the opening 12 decreases in the peripheral direction. For practical use of the magazine 1, this means that, with one turn of the transport wheel 9 starting from the feed opening 7 through the incline 20, the wire terminations 2 are pressed steadily deeper into the recesses 10. At the same time, the edges 11 of the recesses 10 are guided closer to the housing wall 13 by the spiral section 14 of the housing wall 13. The connecting bridges 3 of the wire termination strip 4 are thus not only radially severed, but rather severed from bottom to top, i.e., axially and parallel to the axis of rotation 8 of the transport wheel 9.

[0048] The connecting bridges 3 of the wire termination strips 4 are, in this case, preferably not completely severed. A small remnant of the connecting bridges 3 remains when the wire termination 2 is located in the assembly position. In this way, the wire termination 2 cannot be moved accidentally into the housing 5. Even when a conductor, not shown, with its stripped end is fed through a conductor feed opening 21 into the wire termination 2 in the assembly position, the force that is exerted when fed to the wire termination 2 is sufficient to sever the connection completely.

[0049] The assembly position can be determined easily using a positioning system 22. In this case, this is a spring-loaded round-headed catch inside the housing 5. When the transport wheel 9 is brought into rotation by a user from outside via a feed element 23 in the form of a feed wheel, latching recesses 24, which are made in the shaft of the transport wheel 9, are moved via a sphere that is loaded with a spring force. In this case, the sphere works as a latching catch at the corresponding latching recesses 24, so that each time the sphere is pressed into a latching recess 24 by the spring force, the user is alerted via the easily-detachable latching connection to the fact that the assembly position of another wire termination 2 has been reached.

[0050] FIG. 3 shows the embodiment according to FIG. 2 in a side view without wire terminations 2. As a result, the guide channel 19, which declines in height over the periphery because of the incline 20, is clearly depicted. The wire terminations 2 are pressed further and further into the recesses 10 because of the continuous incline 20, and at the same time, the recesses 10 are axially partially separated from one another by the edges 11.

[0051] FIG. 4 shows a part of a magazine 1, again without wire terminations 2. The opening 12 in the housing base 6 can be seen. The opening 12 is located below the assembly position of a wire termination 2. If a wire termination 2 is arranged in the assembly position, a conductor can be plugged with its stripped end into the wire termination 2 through the conductor feed opening 21. By pressing the conductor further down, the connection between the wire termination 2 and the wire termination strip 4 is completely severed. Together with the conductor, the wire termination 2 can then be guided through the opening 12 and then further processed. After the processing, the crimped wire termination 2 together with the conductor can be removed from the magazine 1, and the transport wheel 9 can be rotated until the assembly position of the next wire termination 2 is reached.

[0052] 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 configured as a gear over the periphery. As a result, it is more slip-proof for a user and simplifies the rotation. Moreover, it projects laterally beyond the housing cover, in order to make it easier for the user's fingers to reach. The feed element 23 has multiple circular recesses 25, since it can rotate together with the transport wheel 9 and thus relative to the housing 5. The circular recesses 25 are thus positioned above the wire terminations 2, so that with each rotation of the transport wheel 7 into the assembly position of a wire termination 2, a circular recess 25 is arranged above the conductor feed opening 21 in order to make it possible for a conductor to be fed into the wire termination 2 in the assembly position.

[0053] FIG. 6 shows a magazine 1 with the upper wall 18 of the housing in which a conductor feed opening 21 is made. The feed element 23 is arranged on the housing base 6 and can be reached only 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 rather is arranged offset in this respect.

[0054] FIG. 7 shows the arrangement of the feed element 23 according to FIG. 6, together with the transport wheel. The feed element 23 is connected via a gear system 26 to the transport wheel 9, so that the feed element 23 can be arranged offset to the transport wheel 9. Because of the configuration of the gear system 26, a rotation of the feed element 23 results in a reverse rotation of the transport wheel 9, which can be advantageous for operation depending on the arrangement of the magazine 1 on a hand tool. Other types of gear systems for a reverse rotation of the transport wheel 9 in the case of a rotation of the feed element 23 are also easily conceivable, however, for corresponding applications.

[0055] FIGS. 8 and 9 show a hand tool 27 for crimping wire terminations 2 or more precisely for crimping wire terminations 2 with stripped conductor ends or with the stranded wires of a conductor in various views. The hand tool 27 has a pliers-like handle 28, which is designed to move multiple die stocks toward one another, not shown. The die stocks form a depression, into which the wire termination 2 is inserted and can be crimped. A magazine 1 for processing wire terminations 2 is fastened to the hand tool 27. In this case, the magazine 1 is arranged so that the opening 12 of the magazine is positioned so that running a wire termination 2 with a plugged-in conductor through the opening 12 from, at least partially, the magazine 1 causes the wire termination 2 to be automatically inserted into the depression. The opening 12 is thus arranged directly above the depression. The wire terminations 2 are introduced into the magazine 1 in continuous wire termination strips 4 and separated inside the magazine 1. Through the conductor feed opening 21, a conductor can be plugged into a wire termination 2, which is located in the assembly position. If the conductor is inserted further into the conductor feed opening 21, the conductor together with the wire termination 2 is routed through the opening 12 of the magazine 1 directly into the depression of the hand tool 27 and ideally positioned. Using the hand tool 27, a crimping connection can then be produced between the conductor end and a wire termination 2. According to the crimping method, the conductor together with the wire termination 2 are extracted from the magazine 1. The feed element 23 can then be further rotated, so that another wire termination 2 is brought into the assembly position, and the next crimping process can be started.

[0056] FIGS. 10 and 11 show a hand tool 27 with a handle 28 in two different views. A magazine 1 for processing wire terminations 2 according to FIG. 5 is arranged on the hand tool 27. The magazine 1 has a feed element 23, which can rotate in the same axis of rotation 8 as the transport wheel 9 inside the magazine 1. The feed element 23 is arranged outside on the housing 5 of the magazine 1, so that a user can easily reach it. Because of the position of the feed element 23, the feed element 23 has multiple circular recesses 25. At least one of the circular recesses 25 is located specifically inside the magazine 1 above an assembly position of the wire terminations 2. Since the feed element 23 can rotate relative to the housing 5, but at the same time rotates with the transport wheel 9 inside 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 the hand tool 27 that is described in FIG. 8 and FIG. 9.
