Description

Description Assembly tool field of technology

[0001] The invention relates to an assembly tool with a base body, optionally a first one, which is essentially designed as a flat part, wherein the base body extends essentially oriented to a plane, wherein a ring wrench shape is further formed in the base body with an opening axis extending approximately perpendicular to the plane and an access opening formed in one direction of the plane, wherein insertion projections are also provided on the base body.

[0002] The invention also relates to an assembly tool with a first and a second sub-tool, wherein the sub-tools each have a first and second base body designed essentially as a flat part, wherein the first and / or second base body extends essentially oriented to a plane, wherein furthermore a ring wrench shape with an opening axis extending approximately perpendicular to the plane and an access opening formed in the direction of the plane is formed in the first and / or second base body, wherein insertion projections are also formed on the first and / or second base body. State of the art

[0003] Such assembly tools are already known in the prior art. They are frequently used in photovoltaic systems. They are particularly useful for the cost-effective assembly and disassembly of plug-in connection assemblies in photovoltaic systems. 31353N1PCT ha / ha 21.08.2025

[0004] In an assembly tool known from DE 202013104028 Ul, insertion projections are integrally formed with the base body. An assembly tool of this type is also known from US 2024 / 0139914 Al. Summary of the invention

[0005] Based on the prior art presented, the invention deals with the problem of advantageously designing the assembly tool, which may consist of a first and a second sub-tool.

[0006] This task is initially and essentially solved by making the insertion projections movable between a working position and a storage position relative to the base body on which they are provided.

[0007] The insertion points on such an assembly tool can be protected when they are not intended for use. The tool can also be designed so that it requires less space when the insertion points are in the storage position.

[0008] The problem is also solved by the fact that the first and / or second basic body further has a first and, if necessary, a second and, if necessary, further handling features, whereby in any case one handling feature extends perpendicular to the plane.

[0009] In this design, the assembly tool is suitable for use with both ring wrench shapes and ring wrench shapes. 31353N1PCT ha / ha 21.08.2025 The insertion points also make the application of the inserts easier to handle. For example, torque can be applied more effectively.

[0010] In a preferred embodiment, it is also provided that the individually handleable sub-tools can be plugged together.

[0011] The first and / or second base body can be made of plastic. The insertion projections can also be made of plastic. Since the insertion projections are preferably designed as separate parts from the base body, a different material, possibly a different type of plastic, can be used compared to that of the base body.

[0012] It is particularly preferred that the insertion protrusions are made of a metallic material.

[0013] The individually handleable sub-tools can be magnetically connected to each other. In particular, the two handleable tool parts can be magnetically connected in a plugged-in state, in which the individually handleable sub-tools are plugged together.

[0014] One of the two individually handleable tool parts can have a magnet, and the other individually handleable tool part can have a ferromagnetic element that interacts with the magnet. In a particularly preferred embodiment, the ferromagnetic element can be formed by the insertion projections or by a projection forming the insertion projections. In this way, a high degree of functional integration can be achieved. The projection or insertion projections are 31353N1PCT ha / ha 21.08.2025 then designed as a multifunctional part that additionally fulfills the task of magnetic connection with the other individually handleable tool part.

[0015] In particular, two magnets and two ferromagnetic elements are provided for the magnetic connection of the two individually handleable tool parts. Preferably, one individually handleable tool part has two magnets and the other individually handleable tool part has two ferromagnetic elements.

[0016] The insertion projections can extend approximately perpendicular to the plane in the working position.

[0017] With regard to repositionability, it is particularly preferred that the insertion projections are pivotably mounted in the base body. The position corresponding to the working position as well as the position corresponding to the storage position can be designed as a detent position.

[0018] In one possible embodiment, the base body can have a detent feature that is actuated into the locking position by a spring element. To lock the insertion projections, the detent feature can interact with a counter-detent feature, for example, in the form of a recess in the insertion projection.

[0019] The insertion projections can be rotationally fixed to an axle part, via which axle part the insertion projections are inserted into the base- 31353N1PCT ha / ha 21.08.2025 The body is pivotably mounted between the working position and the storage position. The axle component may have a counter-locking feature, such as a recess.

[0020] In one possible embodiment, the spring element can be designed in the form of a leaf spring. Preferably, the locking mechanism can also be formed directly on the leaf spring-like spring element.

[0021] In an alternative embodiment, the spring element can be designed as a cylindrical spring, or, for example, as a cylindrical compression spring, which loads the detent mechanism in the direction of the detent locking position. The detent mechanism can, for example, be formed by a detent ball separate from the spring element.

[0022] With regard to the design of a first and a second sub-tool, it is also preferred that the first and optionally second and optionally further handling features and / or the ring wrench feature and / or the insertion projections are formed on the first sub-tool, while the first through-opening is preferably formed on the second sub-tool. Optionally, a second and optionally a third through-opening may also be formed on the second sub-tool.

[0023] The second and third through-openings can also be designed to accommodate the first and, if applicable, the second handling mold. This can facilitate a plug-in mounting of the two partial tools. 31353N1PCT ha / ha 21.08.2025

[0024] The first and second through-openings are preferably formed at different perpendicular distances to the plane if the plane, considered in this context, passes approximately centrally through the ring wrench shape in the direction of the opening axis.

[0025] The first opening can be shaped particularly like a keyhole. A central circular section of the opening can extend into two essentially rectangular sections on the opposite side. Each of these sections can have a concave, rounded edge when viewed from the central section.

[0026] A projecting part, on which the insertion projections are preferably formed, can also be formed wholly or partially, optionally in one piece and preferably also in the same material as the insertion projections, from a metallic material, in particular from a magnetizable metallic material.

[0027] The first and second handling features can be aligned with each other in a longitudinal direction of the assembly tool. Alternatively or additionally, the ring wrench feature can be arranged in a longitudinal direction aligned with one or both handling features. Particularly preferably, the first handling feature has a longitudinal extension that differs from that of the second handling feature. In particular, the through-openings are designed to be complementary to the handling features or the ring wrench feature. This ensures that the two individually handleable tool parts can only be plugged together and / or connected in a predetermined orientation relative to each other. 31353N1PCT ha / ha 21.08.2025

[0028] In particular, the through-openings are designed to complement the handling features or the ring wrench shape.

[0029] The first and second handling shapes, and optionally the ring wrench shape, can be arranged transversely, especially perpendicularly, offset from each other to the longitudinal direction.

[0030] The first individually handleable sub-tool can have a thickness, i.e., an extent transverse, particularly perpendicular, to the plane, such that the handling element, in an assembled state in which the individually handleable sub-tools are connected to one another, does not project beyond the first individually handleable sub-tool in a direction transverse, particularly perpendicular, to the plane. In particular, a free end of the handling element facing away from the base body of the second sub-tool, and in particular an end face facing away from the base body of the second sub-tool, can be arranged flush with a surface of the first individually handleable sub-tool facing away from the base body of the first sub-tool.

Description of the embodiments

[0032] A mounting tool 1 is shown and described, initially with reference to Figures 1 and 2 as well as 25 and 26. In the first embodiment shown in Figures 1 to 24, as well as in the second embodiment shown in Figures 25 to 38, it consists of two sub-tools, the first sub-tool 2 and the second sub-tool 3. 31353N1PCT ha / ha 21.08.2025 Sub-tools 2, 3 are also shown, for example, in Figure 15 or in Figure 35.

[0033] The assembly tool 1 comprises, with respect to the sub-tools 2 and 3, a first base body 4 of the first sub-tool 2 and a second base body 5 of the second sub-tool 3. The base body 4 or 5 extends substantially in or parallel to a plane E that penetrates the base body 4 or 5 or extends parallel to it. The base body 4 or 5 may also be structured, for example, by means of a rim 6, handling features 7, a through-opening 8, a ring wrench feature 9, or insertion projections 10, 11.

[0034] The assembly tool 1, or more specifically, in the exemplary embodiments, the second sub-tool 3, has the aforementioned ring-shaped wrench shape 9. As can be seen, for example, in Figure 9, but also in Figures 12, 14, 15, and 16, and furthermore, with regard to the second embodiment, in Figures 25 and 28, the ring-shaped wrench shape 9 is designed with an opening axis A extending approximately perpendicular to the plane E. The ring-shaped wrench shape 9 also has an access opening 12 extending in the direction of the plane E. The ring-shaped wrench shape 9 is preferably formed approximately centrally with respect to a longitudinal extension of the second sub-tool 3.

[0035] The first and / or second sub-tool 2, 3 preferably has a substantially elongated rectangular plan view. Preferably also with two long sides and two short sides. One or both short sides can be rounded, and preferably circularly rounded. 31353N1PCT ha / ha 21.08.2025 One or both long sides may also have an edge that deviates from a straight line. The edge may, for example, be slightly wavy. A length L corresponds approximately to twice or more, up to, for example, three times or more, preferably approximately 2.5 times, a width b of a tool part 2, 3. A thickness d of the combined two tool parts 2 and 3 may correspond to one-twentieth to one-fifth, preferably approximately one-tenth, of the length L and / or one-third to one-fifth, preferably approximately one-quarter, of the width b. For a single tool part 2 or 3, these values ​​are halved.

[0036] In such a first or second sub-tool 2, 3, the ring wrench shape 9 can have an access opening 12 extending into one long side. Furthermore, the access opening 12 can be located approximately centrally with respect to the longitudinal extent of the first and / or second sub-tool 2, 3.

[0037] The base body, in the exemplary embodiment the base body 5 of the part tool 3, also or alternatively the already mentioned insertion projections 10, 11 are provided.

[0038] In the exemplary embodiment, and preferably, the insertion projections 10, 11 are movable between a working position, as shown for example in Figure 15 or also in Figure 35, and a storage position, as shown for example in Figure 1 or also in Figure 25.

[0039] For this purpose, the insertion projections 10, 11 are formed on a projection part 13, see also figures 14, 23, 30 or 35. 31353N1PCT ha / ha 21.08.2025

[0040] In the exemplary embodiments, and preferably, the projection part 13 is pivotably mounted on the assembly tool 1, here preferably the partial tool 3, for moving the insertion projections 10, 11 into the working position or into the storage position.

[0041] As can be seen in further detail from Figures 14 to 23 or Figures 32 to 35, the projection 13 has freely projecting insertion projections 10 and 11. Overall, the projection 13 is essentially U-shaped, with the legs of the U being formed by the insertion projections 10 and 11. A pivot axis is formed in the area of ​​the corresponding U-shaped section, which in the exemplary embodiment and preferably by two axis parts 14 and 15. Here, the axis part 15, which is also a possible embodiment for the pivot axis as such, is positively engaged in the projection 13, so that it is not rotatable relative to the projection 13.

[0042] The axle part 15 of the first embodiment preferably has one or more flattened sections 16, 17 on its outer projecting part, see for example Figures 4, 6 and 10. By means of a flattened section 16 or 17, the axle part 15 of the first embodiment preferably has one or more flattened sections 16, 17 on its outer projecting part, as shown, for example, in Figures 4, 6 and 10. 17 can interact with a detent element, here a spring element 18. The detent element, preferably the spring element 18, is held in the base body 4, 5.

[0043] In further detail, as can be seen from Figures 21 to 23, the flattened area 16, 17 has a recess 19 or 20. This recess 19 or 20 can interact with a detent 21 on the spring part 18 to stabilize the respective position. 31353N1PCT ha / ha 21.08.2025

[0044] The projecting part 13 further features, with regard to its extension in the storage position, a loop 22 preferably located opposite the insertion projections 10, 11 in plane E. In the storage position, the loop 22 projects outwards. It can be used, for example, to hold the assembly tool 1 in its entirety. With regard to the aforementioned preferably elongated rectangular plan, the projecting part 13 and, accordingly, the loop 22 can also be formed on one narrow side.

[0045] Due to the design of the eyelet 22 on the projection 13, the eyelet 22 is only present on the narrow side in the storage position. In the working position, the corresponding section of the projection 13, or preferably the entire projection 13, extends approximately perpendicular to the plane.

[0046] The sub-tools 2 and 3 can be plugged together as shown.

[0047] The plug connection can be achieved, firstly, by one or more handling features 7 on one of the sub-tools, here sub-tool 2, which, in the assembled state (see also, for example, Figures 5 and 13 or Figure 29), penetrate a second and, optionally, a third through-opening 23, 24 in the exemplary embodiments. The second and, optionally, third through-opening 23, 24 can have a tight fit, so that the plug connection is formed.

[0048] Alternatively or additionally, a magnetic connection can also be provided for the plug connection and to ensure the plug connection is maintained. 31353N1PCT ha / ha 21.08.2025 For this purpose, a magnet 25, see for example Figures 7 and 15, can be provided in one base body 4, and a magnetizable part or ferromagnetic element 25' can be provided in the other base body 5.

[0049] In the first embodiment, and preferably, the magnet 25 (see, for example, Figure 7) is arranged in the base body 4 of the sub-tool 2, and more preferably in the area of ​​the sub-tool 3 in which the projection 13 is located. In this embodiment, and preferably, the projection 13 is a metallic part, so that it can readily serve as a magnetizable element for the magnet 25 in the respective other sub-tool. The projection 13 can thus be designed as a ferromagnetic element 25'.

[0050] The handling features 7 are preferably, as can be seen, for example, from Figure 2, but also from Figures 7 and 8, not aligned with each other in the longitudinal direction 1 of the assembly tool 1 or one of the sub-tools 2, 3, but slightly offset from each other. This allows for a more favorable application of leverage by the user.

[0051] The handling features 7 are also preferably designed as flat parts that have a longitudinal extension in the direction of the base bodies.

[0052] Furthermore, a keyhole-shaped first through-opening 8 is formed on the assembly tool 1 or one of the sub-tools 2 or 3, in the exemplary embodiments, on sub-tool 2. The keyhole-shaped through-opening 8 is opposite the plane extension of the base body 4 or 3. 31353N1PCT ha / ha 21.08.2025 5 is formed perpendicular to the plane E, while the plane E penetrating the base body 4 or 5 preferably extends through the second and third through-openings 23, 24. With respect to the longitudinal extension of the respective sub-tool, this keyhole-shaped through-opening 8 is also preferably formed approximately longitudinally centrally.

[0053] The first through-opening 8 is accordingly formed on a round part 26 rising from the base body 5, preferably having an approximately circular plan. The round part 26 preferably rises less far with respect to the plane E than the first and / or second handling feature 7.

[0054] In the assembled state, as can be seen from Figure 1 or Figure 25, the ring wrench shape 9 and the first through-opening 8 are approximately aligned with each other, viewed perpendicular to the plane E.

[0055] With reference to Figures 25 to 38, a second embodiment is shown. The following description essentially highlights only the differences from the first embodiment. Otherwise, the descriptions of the first embodiment also apply to the second embodiment.

[0056] The second embodiment differs from the first embodiment essentially in the design for locking the insertion projections 10, 11 in the working and / or storage position.

[0057] At least one pin-shaped axle part 14, 15, here in particular the axle part 15, is connected to each other by two 90 degrees around the circumference. 31353N1PCT ha / ha 21.08.2025 provided with offset recesses 19 and 20 for locking interaction with the locking form 21 of the associated sub-tool 3 or its base body 5.

[0058] In the second embodiment, as shown in Figure 30, the detent feature 21 is designed as a detent ball which is biased towards the recess 19, 20 in the axle part 15 by a spring element 18 in the form of a cylindrical compression spring. The spring element 18 is supported at one end against the base body and acts on the detent ball at the opposite end.

[0059] The end of the axle part 15, which has the recesses 19, 20, as well as the spring part 18 and the detent 21, are received in a (initially) open-ended pocket 27 of the base body 3. In the first embodiment, if the spring part 18 is designed as a compression spring acting on a detent ball, the pocket 27 can remain open for normal use of the assembly tool 1. In the second embodiment, if the spring part 18 is designed as a compression spring acting on a detent ball, the pocket 27 is preferably closed during normal use of the assembly tool 1. For this purpose, a plug-like cover 28 can be provided that covers the spring part 18 and the detent ball (see Figures 30 to 33). The cover 28 can fit precisely into the pocket opening and leave a clearance for the end of the axle part 15.

[0060] With reference to Figures 39 to 49, a third embodiment is shown. The following description essentially highlights only the differences from the first and second embodiments. Otherwise, the descriptions of the first and second embodiments also apply accordingly to the third embodiment. 31353N1PCT ha / ha 21.08.2025

[0061] The third embodiment differs from the first embodiment primarily in the design for locking the insertion projections 10, 11 in the working and / or storage position. The locking mechanism is designed according to the second embodiment, as shown in Figures 25 to 38.

[0062] The first sub-tool 2 according to the third embodiment has at least one grip area 29 on an outer surface oriented at least substantially perpendicular to the plane E, with a roughened, in particular grooved, outer surface 30, as shown by way of example in Figs. 40, 44 and 45. The grip area 29 with the roughened outer surface 30 increases the grip of the first sub-tool 2. The grip area 29 can, for example, be formed by indentations in the outer surface 30. In particular, the sub-tool 2, and thus the assembly tool 1, can be gripped by a user in a particularly firm and comfortable manner. In this way, a particularly high force can be generated by a user and transmitted to the assembly tool 1 or the first sub-tool 2. At the same time, a high level of user comfort can be achieved.

[0063] In the third embodiment, the first handling form 7 and the second handling form 7 are aligned with each other in the longitudinal direction 1. As shown in Fig. 39 and Fig. As shown in Figure 40, the ring wrench shape 9 can also be aligned with the first and second handling shapes 7.

[0064] The first handling form 7 can have a different geometry, in particular parallel to the plane E, than the second handling form 7. Preferably, the first handling form 7 has a first through-opening 23 and the second handling form 7 has a 31353N1PCT ha / ha 21.08.2025 The second through-opening 24 is assigned. The through-opening 23, 24 is particularly preferably designed to be at least substantially complementary to the handling feature 7 assigned to it. In this way, the first individually handleable sub-tool 2 can only be plugged into the second individually handleable sub-tool 3 in a defined position relative to it.

[0065] As shown by way of example in Fig. 40, the two handling forms 7 can have the same extent perpendicular to the longitudinal direction 1. The handling form 7 shown on the left in Fig. 40 has a greater extent in the longitudinal direction 1 than the handling form 7 shown on the right in Fig. 40. The through-openings 23, 24 are designed to be complementary to the two handling forms 7 in such a way that the first sub-tool 2 can only be plugged into the second sub-tool 3 in the relative position to the second sub-tool 3 shown in Fig. 40. Due to the different extents of the handling forms 7 and the through-openings 23, 24 in the longitudinal direction 1, the second sub-tool 3 cannot be pivoted 180° about the opening axis A relative to the position shown in Fig. 40 and then plugged into the first sub-tool 2.

[0066] In the third embodiment, and preferably, the base body 4 of the partial tool 2, and further preferably associated with the area of ​​the partial tool 3 in which the projection part 13 is located, has a first magnet 25.1, as shown, for example, in Fig. 45. The projection part 13 is preferably designed as a ferromagnetic element 25'.

[0067] Furthermore, in the third embodiment, it is provided that the base body 4 has two magnets 25, see for example Figure 45, and the base body 5 has two magnetizable parts or ferromagnetic elements 25'. 31353N1PCT ha / ha 21.08.2025 The magnets 25 are preferably arranged in opposite end regions of the base body 4 with respect to the longitudinal direction 1. Thus, the magnet 25 can transition into the edge ridge 6 or be directly adjacent to it, as shown by way of example in Fig. 44.

[0068] In an end region of the sub-tool 3 or base body 5 opposite the longitudinal direction 1 to the projecting part 13, a further ferromagnetic element 25' is provided, which is associated with and / or interacts with the second magnet 25.2. Through the interaction of two magnets 25 with two ferromagnetic elements 25', the two individually handleable sub-tools 2, 3 can be connected to each other in a particularly reliable manner when assembled. Unintentional separation of the two sub-tools 2, 3 can then be effectively prevented.

[0069] As illustrated by Fig. 41 in conjunction with Fig. 42, the first sub-tool 2 extends perpendicular to the plane E such that, when the sub-tools 2 and 3 are connected, the first and second handling forms 7 do not project beyond the first sub-tool 2 in a direction perpendicular to the plane E. The assembly tool 1 can then be gripped by a user in a particularly comfortable manner.
