    Description: The invention relates to a clamping and connection arrangement for the external lightning protection, comprising a clamping body and a clamping screw, wherein the clamping body has a passage opening for the clamping screw with a top side directed toward the screw head and an underside facing the screw end ¬ side recesses for leading receiving a conductor and the screw head Einendbeyond this corresponding breakthrough has, wherein the screw head consists of a stopper portion and an extension which dips into the through hole of the Klemm¬körpers, according to the preamble of claim 1.
    From DE 10 2006 055 751 B3 a terminal for connecting lightning conductor wires is already known.
    The local terminal comprises a base body, a clamping plate and a clamping screw. The clamping screw passes through the body. The clamping plate has on both sides of the clamping screw parallel to each other bulges. At one end of the clamp there is a central projection directed down to the top of the body. In order to accomplish an optimum connection of two conductor wires oriented perpendicular to one another, the front side of the clamping plate and the inner side of the attachment are dimensioned relative to one another such that a conductor wire to be inserted there between this inner side of the attachment and the front side of the attachment Clamping plate is formschlüs¬sig fixed.
    Although the technical solution described can interconnect criss-cross round conductors, however, a tightening of the terminal is only possible from the bottom. The counteracting during tightening torque must be taken on the ladder located in the terminal, which leads to difficulties in applying larger torques.
    From the generic DE 299 17 423 U1 a construction clamp made of metal, in particular for lightning protection previously known to be¬festigen conductor wires to structural parts.
    In addition to the provided there basic construction of a stamped and bent part with U-shaped common connecting part, one leg of which is penetrated by at least one Druck¬ screw, and the existing notched terminal tab, which protrudes from the base of the U-shaped connecting part is a clamping body is present, which is penetrated by a clamping screw.
    The clamping screw has a screw head with an aperture for receiving a lightning arrestor wire. The clamping body itself comes in case of application in abutment with the aforementioned stamped and bent part. To fix the respective arrester wire, the clamping body, there referred to as a shim plate, adapted to the corresponding conductor, in the shaft-passage intersecting insoles.
    When mounting using the construction clamp to DE 299 17 423 U1 the installer must pay attention to the position of the clamping screw to Klemmkör¬per when clamping the round conductor, so that the conductor comes to rest in the corresponding Einlegerinne.
    In addition, it is not possible in the prior art construction to allow higher tightening forces and thus larger torques to take effect without the risk of the conductor being subjected to deformation.
    From the foregoing, it is therefore an object of the invention to provide a further developed clamping and connection arrangement for the external lightning protection, consisting of a clamping body and a clamping screw, wherein the arrangement to be created safe installation without incorrect positioning and the application of larger tightening torques should allow.
    The solution of the object of the invention is carried out by the combination of features
    Claim 1, wherein the dependent claims represent at least expedient refinements and Weiter¬bildungen.
    It is therefore assumed by a clamping and connection arrangement for the outer lightning protection, consisting of a clamping body and a clamping screw. The clamping and connecting arrangement should be able to receive both round conductors and flat conductors and thus be universally usable.
    The clamping body has a through-opening for the clamping screw with an upper side directed towards the screw head of the clamping screw and an underside directed towards the screw end of the clamping screw.
    The upper side has recesses for the leading reception of a conductor and the screw head has a corresponding breakthrough in this respect. This may be e.g. circular breakthrough act with semicircular grooves on the top of the clamping body. The recesses or the corresponding breakthrough may, however, also be deviating from the circular, e.g. rectangular shape, preferably for flat conductors own.
    The screw head also has a stopper portion and an extension, the latter being immersed in the passage opening of the clamp body. The stopper portion rests on the conductor to be fastened in the case of installation.
    According to the invention, the extension of the screw head is formed on the outer peripheral side as a key area. In the simplest case, this can be a key area that is complementary to the shape of a classic open-end or open-end wrench.
    However, the key surface can also have a polygonal shape, quasi complementary complementary to the shape of a classic ring wrench.
    The passage opening of the clamping body has a respective korrespondieren¬de inner contour. This makes it possible, the clamping screw in the clamp body verdrehgesi¬chert to lead. In addition, a further key surface is provided on the outer circumference of the clamping body. This further key surface serves to counter hold when tightening the clamping and connecting arrangement with clamping screw and associated nut.
    In particular, when using the clamping and connecting arrangement for fixing of conductors or flat conductors on construction elements with a flat cross section, this can also be a flat conductor in this regard, the threaded end of the clamping screw is inserted through a bore located in the construction element and the screw clamping connection by means of nut and if necessary spring ring or circlip realized.
    In a further development of the invention, the key surface on the extension of the key body and the corresponding inner contour of the clamping body are designed such that an angular offset twisting and insertion can be made with respect to the position between the clamping screw and clamping body.
    By such a measure in conjunction with different recesses on the upper side of the clamp body, the clamping of conductors of different geometri¬scher shape or round conductors of different diameters can be simplified and done safely.
    In the aforementioned sense, the aperture in the screw head has dimensions corresponding to the cross-sectional area of the conductor to be clamped. If round conductors are to be clamped, the opening is, for example, designed as a bore with a semicircular cross section. If flat conductors are to be clamped, the aperture has a rectangular or possibly square cross section.
    As already explained, the recesses located on the upper side of the clamping body can have a different geometry such that conductors of different dimensions can be clamped. These recesses may e.g. be designed as a classic channel with a semicircular cross-section, but also as a V-shaped notch.
    The clamping and connecting arrangement is preferably made of stainless, machined by turning and / or milling metallic materials.
    Then, when the aforementioned key surfaces correspond to the principle of wrench surfaces, it is possible to manufacture the clamping and connection assembly cost, since it is assumed that simple turned parts, which receive the desired key surfaces in the subsequent milling step.
    Although the invention makes reference to the use of the clamping and Verbindungsanungsanordnung for the field of external lightning protection. In principle, however, the invention is also applicable to other mechanical connections of construction elements of different cross-sectional shape and dimensions when it comes to effecting a secure positional assignment of these construction elements and to connect them to larger torque segments in a force-fit manner.
    The invention will be explained in more detail below with reference to an embodiment and Zu Zu Zunahme taking figures.
    1 is a perspective view of the clamping and connecting arrangement with the most essential functional components, namely clamping screw, clamping body and nut and locking ring. Fig. 2 is a perspective view similar to that of Fig. 1, but with a structural element, e.g. a flat conductor; Fig. 3 is a representation similar to that of FIG. 2, but here already in the
    Breakthrough of the screw head inserted round conductor, e.g. a lightning arrester wire for external lightning protection; Figure 4 is another perspective view with a received round conductor, but having a reduced diameter and in this respect lies in a recess on the upper side of the clamping body, which in this case has been realized as a V-shaped notch; 5 shows a perspective view of the clamping and connecting arrangement similar to that according to FIG. 4, wherein here the clamping was realized solely by a 90 ° twisting between clamping body and clamping screw in order to have a conductor with a smaller cross section 6 is a perspective view of the clamping and connecting arrangement, which has been developed so that a flat conductor can be clamped instead of a round conductor, in which respect the opposite recesses on the upper side of the clamping body against the geometric shape, ie the cross section of the flat conductor, are adapted, which also applies to the korrespondie¬render recess on the underside of the stop portion of the screw head.
    As can be seen from the figures, the clamping and connecting arrangement consists of the basic components of a clamping screw 1 and a clamping body 2. The threaded end 3 of the clamping screw 1 with a conventional, such as hexagon nut 4, optionally with the use of a spring or locking ring fifth attached to a structural element 6 (see eg Fig. 2).
    The clamping body 2 has a passage opening for the extension 7 of Klemmschrau¬be 1.
    In this respect, the screw head of the clamping screw 1 consists of a stopper portion 8 and the aforementioned extension. 7
    In the assembled state, the extension 7 of the clamping screw, depending on the inserted and to be clamped conductor, e.g. Round conductor 9 different depths in the clamp body and the existing through hole a.
    The top of the clamp body 2 has recesses 10 and 11 for leading receiving the conductor 9. The opening 12 in the screw head corresponds in this regard.
    The extension 7 of the screw head has wedge surfaces 13 on the outer peripheral side such that e.g. in a simple opposite key surface analogous to the key area of an open-end wrench a 90 ° offset introduction of the clamping screw 1 in the through hole of the clamp body 2 is possible. As a result, e.g. 1 and 2 round conductors of different diameters are securely clamped in the comparison of the representations according to FIGS. a circular conductor of larger diameter with a position between clamping screw and clamping body according to FIG. 2 or round conductor of smaller diameter with a position between clamping screw and clamping body according to the illustration according to FIG. 1.
    The passage opening of the clamping body 2 accordingly has a corresponding internal contour, in order to supply the clamping screw 1 in the clamping body 2 in a manner secured against rotation.
    Furthermore, the outer peripheral side of the clamping body 2, the formation of further key surfaces 14 is realized, so that a counter holding of the clamping and VerbindungsanOrnung when tightening the nut 4 and thereby the application of higher torques is possible.
    Although not shown in the figures, the key surface on the extension of the Schrau¬benkopfes and the corresponding inner contour of the clamping body can also be realized such that a gradual angle offset twisting and insertion with respect to the Positi¬on between the clamping screw and clamping body can be realized. If a multi-tooth configuration is chosen here differently from the opposing key surface shown in the figure, analogously to an open-end wrench surface, smaller angle variants with regard to twisting and at the same time obtaining the desired guidance are possible.
    Fig. 3 shows how the Rundlei¬ter 9 can be fixed by resorting to the breakthrough in the screw head, which is held with its upper side by a corresponding shape in the stop part 8 and the underside of the recesses on the upper side of the clamp body 2. An exact position during assembly is ensured by the wrench flats on the extension of the head of the wearer and the corresponding inner contour in the passage opening of the clamping body.
    4 shows how, using the recess 11 with a V-shaped cross-section, a conductor 9 with a reduced diameter can be securely fixed, using one and the same clamping and connection arrangement with only a 90 ° turn ¬hung between clamping screw and clamp body.
    Fig. 5 shows a similar realization form as shown in Fig. 4, but here the clamping of a conductor 9 of smaller diameter is achieved solely by the fact that this conductor 9 is laterally supported by the recess in the abutment portion 8 of the clamping screw.
    6, not only flat conductors or flat construction elements with a round conductor can be fixed by the proposed clamping and connection arrangement. Rather, it is also possible to connect a construction element 6 with a flat cross-section with a flat conductor 15 by clamping. In this regard, as can be seen and understood by those skilled in the art from the figure, the recesses on the top of the clamping body are rectangular groove-shaped. Also in this regard, rectangular groove-shaped recesses are formed in the abutment portion 8 of the clamping screw. The breakthrough in the screw head here, of course, likewise corresponds to the cross-sectional shape of the flat conductor 15.
