    TECHNICAL AREA
    The invention relates to a ground terminal for the equipotential bonding and / or grounding of electrical equipment, lightning protection or other equipment.
    STATE OF THE ART
    Grounding terminals are used inter alia to produce a potential equalization of electrical installations in buildings. They are also used in lightning protection systems. Various ground terminals are known from the prior art.
    US 2010 227 483 was published 09.09.2010 in the name of Mike Vernica and shows a ground terminal. This comprises two bow-shaped clamping elements, which are connected to each other via two screws so that the distance of the clamping elements can be reduced by rotation of the screws, for. to clamp an interposed pipe. A disadvantage of this earthing clamp is that one of the two screw connections must be completely loosened for their installation on a pipe. On the one hand there is the danger that the free screw will be lost. On the other hand, the subsequent restoration of the screw connection with limited accessibility u.U. to be difficult.
    EP 1 398 850 A1 was published on 17.03.2004 in the name of AGRO AG and shows a Erdleitungsbride made of bent sheet metal. This will be fixed with a clamp to a pipe of a pipeline. In order to be able to connect ground wires both in a transverse and in a series connection, this earth conductor has a clamping element which has a plate as a clamping element rotatable about the axis of a central clamping screw. This forms two passages for a longitudinal circuit and two passages for a transverse circuit.
    DE 7 638 349 U1 was published on 31.03.1976 in the name of the company Hermann Kleinhuis and shows a Erdungsrohrschelle that can be firmly connected to pipes of different diameters and connect both cut, as well as continuous uncut grounding. The clamp comprises two parts, wherein one of the two clamp parts has an extension beyond the clamping member, which carries the contact terminal for connection of a grounding line. The lower clamp member is formed as a flat bar with a transverse to its longitudinal direction retaining groove. The upper clamp member is bent substantially angularly and has a plurality of recesses for engaging a bent tongue of the lower clamp member in its in the assembled state a pipe engaging behind leg. A screw allows the earthing clamp to be clamped on a pipeline.
    US 5 281 761 was published on January 25, 1994 in the name of Burndy Corporation and shows a system for grounding an electrical cable to a ground electrode, such as a water pipe. This comprises an upper part with a mounting surface and a curved saddle and a lower part with at least one U-bolt which has a thread at both ends. On the mounting surface, a crimped cable end can be fastened in several angular positions relative to the water pipe by means of a screw connection. When mounted on a ground electrode, the U-bolt, together with the bent saddle, includes the grounding electrode, the two ends of the U-bolt passing through holes in the bent saddle and bolted thereto by nuts and washers. Due to the large number of screws, nuts and washers, the installation of such systems is relatively cumbersome and there is the latent risk that lost or forgotten parts. Therefore, such systems are only limited for mounting in hard to reach places. Likewise, under some circumstances, such systems may find it difficult to maintain long-term contact force necessary for safe grounding.
    PRESENTATION OF THE INVENTION
    An object of the invention is to show a ground terminal, which can be mounted more easily and has better values compared to the prior art. Another object of the invention is to show a ground terminal which is suitable for different pipe diameters.
    An inventive earth terminal generally has an upper part with a base body and a clamping device for at least one grounding line. Furthermore, the ground terminal comprises a likewise curved in the mounted state arcuate lower part, which is operatively connected via a first and a second operative connection means with the upper part. In an operatively connected state, the upper part and the lower part form an advantageously at least partially round receiving opening, which serves to receive a cylindrical tube or a rod. The upper part and / or the lower part may be arcuately curved or even kinked. In particular, the upper part may have a curved and / or kinked base body, which forms part of the receiving opening. Other configurations and cross-sectional shapes are possible. The first and the second operative connection means are advantageously arranged substantially diametrically opposite one another with respect to the receiving opening. In certain embodiments, the lower part is less rigid compared to the upper part in the circumferential direction, such that it deforms more than the upper part when it is applied to a cylindrical counter body depending on its diameter.
    Depending on the embodiment, the lower part of sheet metal and / or wire and / or plastic may be formed. The upper part serves primarily for the transmission of electrical currents. It has for this purpose at least one lying in the interior of the receiving opening contact surface, which serves for contacting the cylindrical tube or the rod (hereinafter generalized also counter-body). In order to reduce the variety of ground terminals necessary for contacting the usual counter-bodies, the contact surface is advantageously designed such that a sufficiently large common electrical contact area between the upper part and the counter body of different dimensions to be contacted is ensured. This can be achieved, for example, by a specially chosen constant or by a variable curvature of the contact surface, e.g. geared to the diameter of the most common piping can be achieved. A particularly good alignment of a ground terminal relative to the counter body can be achieved if the lower part comprises two straps spaced apart from each other.
    The main body of the upper part is advantageously made of a material having a good electrical conductivity. Good results are achieved with brass and / or bronze and / or aluminum. The lower part, which serves primarily for fastening the upper part can be made of a material having a lower electrical conductivity. In general, such materials are cheaper, which has a positive effect on the manufacturing cost. The main body of the upper part can be produced in an extrusion process and / or a casting process. In a preferred embodiment, the upper part and the lower part are operatively connected to each other via an operative connection means, which comprises a hook and a loop-shaped counterpart.
    The clamping device which is arranged on the upper part and serves for clamping a grounding line or the like, has in a preferred embodiment, a clamping base and a means of a clamping screw on the clamping base fixed clamping plate. Such a clamping plate need not be plate-shaped, but may e.g. also be arcuate. The clamping plate may comprise a support element which cooperates in the assembled state with a stop of the clamping base, so that when clamping a grounding line or the like tilting of the clamping plate relative to the clamping base is prevented. In a variant, the clamping plate can be rotated about the clamping screw from a first to a second position, such that grounding lines can be clamped in at least two different directions. The clamping device may comprise a spring which serves as a restoring element and presses the clamping plate away from the clamping base. Such an embodiment of the invention may be advantageous because it ensures that the clamping plate and the clamping base remain separated from each other until the actual clamping, so that a grounding line can be easily inserted. The spring may e.g. be a coil spring, respectively a coil spring, whereby a simple production of the ground terminal is possible. Other types of springs, such as Bend springs are possible. Details of the design and the operation will be explained in more detail below.
    If desired, the clamping plate may comprise a bent sheet metal part. As a result, on the one hand, the production costs can be reduced and, on the other hand, a reliable electrical connection can be ensured since, among other things, such. In a simple way splicing stranded or stranded ground lines when terminals can be largely reduced.
    A clamping socket may comprise at least one notch. Such a notch can on the one hand improve the positioning / alignment of a grounding line to be clamped and on the other hand also improve the electrical contact between a grounding line and a clamping device. The notch can be arranged directly in the body.
    In a variant of the invention, the clamping base may have a plurality of notches. In a variant of the invention, the clamping base comprises two notches, wherein the first notch is aligned substantially parallel to the longitudinal axis of a counter body to be contacted and the second notch is substantially perpendicular to the first notch. However, the present invention is not limited to such number and alignment of notches. Likewise, a clamping plate may also have at least one notch.
    An easily manufactured grounding terminal with an electrically advantageous contacting can be achieved if the main body of the upper part and the clamping base are integrally formed.
    In order to simplify the clamping of a grounding line, the clamping plate may have a releasable if necessary rotation, which prevents rotation of the clamping plate to the clamping screw. Thereby, a desired relative orientation of the clamping plate to the clamping base can be ensured, both before a grounding line is clamped, and during the generation of such a clamping. In particular, it can be ensured that the clamping plate is not rotated when screwing a clamping screw. A particularly efficient and at the same time simple rotation lock can be generated if a support element simultaneously acts as a rotation lock.
    By using a lower part that is easier to deform than the upper part, it is possible to prevent the ground terminal from being mechanically damaged in the event of suddenly occurring high electrical currents because of the resulting expansion due to the Joule heat, since such a lower part can absorb the deformations occurring without being damaged to become. Such high currents can occur, for example, in lightning protection systems.
    A simple production can be achieved if the lower part is at least partially made of a metal sheet. As a result, parts in large quantities can be inexpensively, e.g. be produced by punching and bending processes. Both good electrical properties and high chemical resistance and ease of manufacture can be achieved if the upper part or its base body is made of a brass alloy. However, the invention is not limited to these materials and it is also a production of copper, bronze, aluminum or other suitable materials possible. For example, To increase the corrosion resistance, coatings are also possible, e.g. with tin.
    Particularly user-friendly grounding terminals can be achieved when the upper part and the lower part are operatively connected to one another with a hook connection and a screw connection with a clamping screw, as explained in more detail below. In this way, a ground terminal can be mounted relatively quickly, and the individual parts remain connected to each other during the entire assembly process captive.
    A good adaptability to mating body of different shapes can be achieved when the upper part and the lower part are operatively connected to each other via a hook connection, wherein one of the two parts has a plurality of hooks and the other has at least one hook in this hook crosspiece. In this way, a ground terminal can be placed around a counter body during assembly in a particularly simple manner and adapted to the cross section, as will be explained in more detail below.
    Alternatively or in addition, a ground terminal also have a plurality of transverse webs, which can be connected to one or more hooks.
    For particular applications, it is advantageous according to the invention, when the upper part and the lower part are operatively connected to each other by at least one clamping screw, which is mounted in a longitudinal opening. This allows a particularly high adjustability between the first and the lower part can be achieved. Such a longitudinal opening may also be a single-sided passage opening.
    A particularly good anchoring of a clamping screw on the lower part can be achieved if it is mounted on the lower part in an operatively connected to this mother. Such a nut may be connected to the base e.g. welded, soldered, pressed or glued. Combinations of such joining methods are also possible.
    The invention described herein is not limited to use for contacting pipes, but may also be used to contact other objects, such as profiles. Likewise, the grounding terminals according to the invention can be used, for example, in the context of lightning protection systems, for instance for contacting downpipes.

    In the following figures and the associated description are corresponding parts, unless otherwise noted, provided with the same reference numerals.
    FIGS. 1-4 show a first variant of a ground terminal 1. FIG. 5 shows a variant of an active connection means. FIGS. 6-7 show a second and a third variant of a ground terminal 1. FIGS. 8 and 9 show a fourth variant of a ground terminal 1. FIGS. 10 to 12 show a variant of a clamping device 6. FIGS. 13-14 show a fifth variant of a grounding clip 1. FIGS. 15-16 show a sixth variant of a grounding clip 1.
    As shown in FIGS. 1-3, 6-9 and 13-16, a ground terminal 1 generally comprises an upper part 10 which has a base body 11 which is curved and / or bent at least in regions in the circumferential direction of a receiving opening 7 , A clamping base 12 forms in the variants shown an integral part of the upper part 10. A clamping plate 14 is operatively connected via a clamping screw 13 with the clamping base 12. The clamping base 12 has a threaded hole 27, which in the sectional view according to FIG. 7 can be seen. By means of rotation of the clamping screw 13, the distance between the clamping base 12 and the clamping plate 14 can be adjusted so that a grounding line 5 is clamped therebetween can (see Figures 812). A spring 15 (coil spring) disposed between the clamping base 12 and the clamping plate 14 pushes the clamping plate 14 away from the clamping base 12. Alternatively, other types of springs may also be used in a grounding terminal of the illustrated embodiment, such as e.g. Bending springs. As a result, the assembly is facilitated since the clamping base 12 and the clamping plate 14 need not be moved apart by hand before introducing a grounding line 5. The clamping base 13 has a bore 16 which has a larger diameter than the spring 15 and which extends over a certain length along the clamping screw 13. The bore 16 serves to receive the spring 15 when the clamping plate 14 rests on the clamping base 12. The arrangement is best seen in Fig. 7, where the clamping device 6 is shown partially cut so that the inner life is visible. The clamping base 13 has in the embodiment shown two at an angle of 90 ° to each other aligned notches 17, which serve for better positioning of the grounding line 5 when clamping. The clamping plate 14 has a central part 24, which has a bore 25 for the clamping screw 13. Furthermore, the clamping plate 13 comprises a support element 18, which can simultaneously serve as anti-rotation. The support member 18 is arranged at a right angle to the central part and extends in the mounted state parallel to a side surface 19 of the clamping base 12. The side surface 19 serves as a stop for the support element 18. The interaction of the support element 18 and the side surface 19 can be prevented be that the clamping plate 14 tilts when connecting the grounding line 5 in an inadvertent manner to the rear, thus affecting the clamping. In the variant shown, the clamping plate 14 also includes an obliquely downwardly projecting clamping fingers 26, which prevents the terminals of the grounding line 5 that this slips laterally from the clamping base 12.
    An advantage of the clamping device 6 shown is that it is suitable for clamping of ground lines in different directions (x and y direction). FIGS. 10-12 show schematically how a clamping device 6 can be brought from a first state, which for example enables a longitudinal connection of a grounding line 5, to a second state, which makes possible a cross-connection, for example. In the initial state shown in Fig. 10, the support member 18 rests on the stopper 19, so that rotation of the clamping plate 14 about the axis of the clamping screw 13, relative to the clamping base 6 is prevented. Thus, the support element 18 acts as anti-rotation. As indicated by the dashed arrow, the clamping plate 14 can be tilted relative to the clamping base 6. To enable such tilting, as shown, e.g. the fit between the bore 25 and the clamping screw 13 arranged therein is dimensioned so that the play necessary for tilting is ensured, as illustrated in FIG. 11. In order to tilt the clamping plate 14, one of the force applied by the spring 15 opposite force must be exerted. After the clamping plate 14 is tilted enough, it can be rotated about the axis of the clamping screw 13, without the rotation of the support member 18 is blocked. After the clamping plate 14 has been rotated to the desired position, the tilting can be ended as shown in FIG. 12 (indicated by the dashed arrow). By the force applied by the spring 15, the support member 18 is then pressed against a stop 19, which causes a defined alignment between the clamping plate 14 and the clamping base 6. Thus, in the embodiment shown, the support element 18 also serves as a type of alignment element which ensures a defined alignment of the clamping plate 14 with the two notches 17 of the clamping base 12.
    The main body 11 of the upper part 10 of the earthing terminal 1 generally has at least one contact surface 20, which serves in the assembled state for the electrical contacting of a tube 4 (see Fig. 8). If necessary, the main body 10 can be configured deformable. The earthing clamp 1 comprises, in addition to the upper part 10 mentioned at the beginning, a bow-shaped lower part 30 which, in the embodiments shown, consists of a sheet-metal strip (cf., FIGS. 1-9), a wire (compare FIGS. 13-14) or by injection molding or extrusion molding Plastic or metal is made (see Fig. 15 - 16). Together with the upper part 10, the lower part 30 encloses a receiving space for a cylindrical body, such as e.g. a pipe or rod or the like. By tightening the operative connection means, the upper part 10 and the lower part 30 can be fixed on the cylindrical body shown.
    In certain applications, good results are achieved when the lower part 30 is less rigid in the circumferential direction compared to the upper part 10, i. E. it has a greater flexibility in comparison to the upper part 10, such that when it is fitted around a cylindrical counter-body 4, such as e.g. the tube 4, in the circumferential direction stronger deformed compared to the upper part 10 as the thus operatively connected upper part 10th
    In a preferred embodiment, the lower part 30 has two mutually spaced straps 39, which create when tightening the active connection means 2, 3 around the counter body and provide a secure fit. If necessary, the two straps 39 can also be operatively connected by one or more transverse webs.
    The upper part 10 and the lower part 30 are operatively connected to each other via a first and a second operative connection means 2, 3. As can be seen in the figures, the operative connection means 2, 3 may have different configurations depending on the field of application.
    For a particularly simple assembly, a first operative connection means 2 is designed as a hook connection. In the embodiments according to FIGS. 1 to 4, 8 and 9 and FIGS. 13 to 14, one or more hooks 22 are formed on the upper part 10. At least one loop-shaped counterpart 34, which has one or more holding rungs 35, is formed on the lower part 30. This can be hung on the hook 22 during assembly. The lower part 30 may have a chamfered end portion 36, which facilitates the mounting of the two parts during assembly.
    A simple assembly is possible if the opposite second operative connection means 3 is designed as a screw connection. For this purpose, a clamping screw 31 is mounted on the upper part 10 in a formed as a hole or thread 21 abutment and on the lower part 30 in an operatively connected with this nut 33. In the released state, the second operative connection means 3 advantageously offers sufficient freedom that the hook connection of the first operative connection means 2 between the upper part 10 and the lower part 30 can be easily released or suspended. This relative displaceability is increased in particular by a hole 21 designed as an elongated hole, which enables a displacement and tilting of the clamping screw 31 relative to the upper part 10 during assembly.
    In Fig. 4 shows in detail an advantageous mounting a nut 33 on a lower part 30. For this purpose, a square nut 33 is clamped between retaining tabs 38 and beads 32 in the shown variant, that relative displacements and rotations between the square nut 33 and the remaining lower part 30 are largely locked. Such storage can be made particularly simple and inexpensive, since no additional joining agents are necessary. Other fixings are possible. Fig. 5 shows another variant for mounting a clamping screw 31 in the lower part 30, in which a nut 33 welded to the lower part 30, or is pressed. Alternatively, a nut can also be glued or a thread can be formed directly on the lower part 30. Combinations of different joining methods or means are also possible. FIGS. 6 and 7 show further variants of first and second operative connection means 2, 3. The upper part 10 and the lower part 30 are mechanically operatively connected to one another via first and second active connection means 2, 3 designed as screw connections. In the embodiment 1 shown in Fig. 7, one side of the upper part 10 is provided with a slot 22 and the other side with a longitudinal opening 23, which serves as a one-sided aligned passage opening. As a result, the ground terminal 1 can be mounted on a device, without having to be completely solved for one of the two screw 2, 3.
    8 and 9 show grounding clamps 1 mounted on pipes 4 of different diameters, wherein in each case a grounding line 5 is connected in transverse (FIG. 8) or longitudinal (FIG. As also shown, with the inventive clamping device 12 grounding lines 5 can be contacted with different diameters well electrically. The grounding terminals 1 each have a plurality of transverse webs 35, whereby the same embodiment can be used for connection to pipes 4 of very different diameters.
    13 and 14 show a variant of a ground terminal 1 according to the present invention, in which the lower part 30 is formed in the manner of a wire bracket. On the upper part 10 more than one type of saw teeth formed hooks 22 are arranged, in which the transverse web of the lower part 30 to match the diameter of the relocating tube - can be hung - as shown in Fig. 14.
    15 and 16 show a variant of a ground terminal 1 according to the present invention, in which the lower part 30 has been produced by means of an extrusion process and is shaped so that it can be hooked on one side at a corresponding end of the upper part 2. The upper part 10 comprises a longitudinal opening 23, which is formed as a one-sided aligned passage opening into which the clamping screw 31 can be switched on or off (indicated by the dashed arrow in Fig. 16). At the lower part 30, the clamping screw 31 is mounted in a nut 33. This has in the embodiment shown on a U-shape, which can at least partially surround the lower part 30. As a result, a positive connection between the lower part 30 and nut 33 can be generated, which prevents screwing in of the nut 33 during insertion or unscrewing of the clamping screw 31. Also, the lower part 30 has an elongated opening in which the clamping screw 31 is mounted. Thereby, the clamping screw 31 can be angled relative to the lower part 30, which facilitates hanging in the longitudinal opening 23.
