  • the mass cam of stainless steel is connected to the element to be grounded. This is often done by welding.
  • welding operations in ferritic weld metal and welding operations in austenitic weld metal are subject to different regulations as well as carried out by different methods, the difficulty lies in providing a further manufacturing process in the manufacture of the element to be grounded for the ground connection, namely Welding of austenitic weld metal (mass cam).
  • Object of the present invention is therefore to avoid the above-mentioned disadvantages of the known from the prior art solutions and to provide an easy-to-assemble mass cam, which can be attached with little effort to the element to be grounded. While complying with all regulations and standards for such a mass cam.
  • a mass cam for attachment to a member to be grounded, characterized in that the mass cam comprises a threaded insert and a sleeve, wherein the sleeve has a sleeve bore, in which a sleeve thread is introduced, wherein the threaded insert has a ground bore, in which a ground thread is introduced., That the threaded insert is screwed via an insert thread into the sleeve bore with the sleeve thread and that a solder between the threaded insert and sleeve is arranged.
  • the mass cam thus consists of two parts, namely a threaded insert and a sleeve.
  • the sleeve is the part of the mass cam, which can be fastened to the element to be grounded. This is done mainly by welding, but can also be attached by other connections, such as gluing. It is important that there is an electrical connection between the sleeve and the element to be grounded.
  • the sleeve may consist of the same material as the element to be grounded, which has the advantage that the manufacturing process, by means of which the element to be earthed is made, can also be used for fastening the sleeve of the mass cam.
  • a welding process by which, for example, a vehicle body is welded may also be used to attach the sleeve to the body.
  • the sleeve according to the invention has a sleeve bore, which in turn includes a sleeve thread. The sleeve thread is thus arranged as an internal thread in the sleeve bore.
  • a threaded insert which has an insert thread as an external thread on the threaded insert. Furthermore, a ground hole is arranged in the threaded insert in such a way that the insert thread extends as an external thread around the ground hole and the ground hole is arranged centrally in the center of the insert thread. The ground bore is thus coaxial with the insert thread.
  • the threaded insert here consists of rostträgem steel, as prescribed for such mass cams.
  • the ground bore in the threaded insert further has a ground thread as a thread in the ground bore, thereby making it possible to produce an electrical ground potential at the mass cam by screw connection.
  • the material of the threaded insert is also electrically conductive, as well as that of the sleeve and that of the element to be earthed so that an electrical connection through the ground thread and the threaded insert and the sleeve and the element to be grounded is ensured.
  • a solder between the threaded insert and sleeve is further provided, which is brought on welding the sleeve on the element to be grounded by the heating of the sleeve to melt and connects the insert thread with the sleeve thread.
  • the solder is designed to match the two substances, namely the sleeve and the threaded insert, durable and resistant to corrosion.
  • the solder is designed as a soft solder.
  • the mass cam is prefabricated in that the solder is introduced into the sleeve and then the threaded insert is screwed into the sleeve. This creates a complete mass cam which can be fastened to the element to be grounded.
  • the solder is designed as a ring and the sleeve according to the invention has a groove above the Hüisengewindes.
  • the annular solder can then be inserted into the groove and is located when screwing the threaded insert into the sleeve exactly between the threaded insert and sleeve.
  • the solder is then melted by the heat transfer and connects ground thread and insert thread.
  • This polygonal surface of the threaded insert is preferably designed so that the surface protrudes beyond the insertion thread in its dimensions.
  • the surface thus has a larger radius than the insert thread. This ensures that when screwed threaded insert into the sleeve, the groove or the solder is covered.
  • Ais solder according to the invention is a soft solder in question, since this has the properties soften by heating the welding process of the sleeve and thus to solder threaded insert and sleeve together.
  • solder ring-shaped and insert it into a groove it is also possible to apply the solder on the sleeve thread or the insert thread during manufacture of the sleeve or the threaded insert. This results in an equally secure solder joint, as when inserting a ring in a corresponding groove.
  • Figure 1 is an exploded view in section through the components of the invention Massenockens.
  • Figure 1 shows in the upper parts of the figure, the two parts of the mass cam, namely threaded insert 1 and sleeve 10 in disassembled position and in the lower part of the figure as a mounted position. In the disassembled position, the two parts are shown in section and in plan view respectively.
  • the sleeve 10 has a sleeve bore 12, wherein the sleeve bore 12 can be arranged centrally or decentrally in the hull 0.
  • This variable arrangement of the Hüisenbohrung 12, the sleeve 10 of the invention can be matched to the respective elements to be grounded.
  • the surface of the sleeve 10 is drawn around, allowing for easy manufacture and easy installation.
  • the sleeve 10 is not limited to this geometry, but other geometries, such as a polygonal surface are possible.
  • the sleeve 10 also has a bottom, by means of which the sleeve 10 can be mounted on the element to be grounded. Such attachment is preferably done via welded joint. But there are also other electrically conductive connections possible.
  • the sleeve 10 has in its sleeve bore 12 a sleeve thread 13, which is arranged as an internal thread in the sleeve bore 12. Above the sleeve thread 13, a groove 1 is mounted, which also extends in a circle around the sleeve bore 2.
  • the groove 1 preferably has a slightly larger radius than the sleeve bore 12th
  • the threaded insert 1 also has a bore, namely a ground bore 2, in which a ground thread 3 is introduced.
  • This mass thread 3 is also provided as an internal thread in the ground bore 2. Due to the mass-material winch 3, an electrical ground potential can be attached to the threaded insert via a screw connection.
  • the threaded insert 1 has a surface and an insert thread 4 located underneath, which is arranged around the ground bore 2 around. Accordingly, the insert thread 4 is introduced as an external thread on the threaded insert 1. The surface is beyond the insert thread 4 addition, so that the surface of the threaded insert 1 has a larger radius than the insert thread 4. This results in the cut through the threaded insert 1 according to the invention a T-shaped component.
  • the threaded insert 1 according to the invention can now be screwed into the sleeve thread 13, so that a screw connection between the sleeve 10 and Thread insert 1 is created.
  • the surface of the threaded insert 1 is designed polygonal, so that when screwing a higher torque can act on the threaded insert.
  • a round surface is conceivable, which has two recesses to allow the screwed mitteis a tool.
  • a solder 20 is arranged between threaded insert 1 and sleeve 10.
  • the solder 20 is annular and is inserted into the groove 11 of the sleeve 1.
  • the solder 20 is thereby arranged on the one hand between the threaded insert 1 and the sleeve 10 and, secondly, the solder and the groove are covered by the surface of the threaded insert 1.
  • the mass cam according to the invention is designed in such a way that, when mounted on an element to be ground, it is heated by a thermal process such as welding such that the solder 20 melts and runs between the sleeve thread 13 and the insert thread 4 , When cooling a solid and permanent, electrically conductive connection between the threaded insert 1 and sleeve 10 is then ensured.
  • the sleeve according to the invention 0 is made of a ferritic weld metal and the threaded insert 1 according to the invention made of austenitic weld metal. Due to the fact that, when the mass cam according to the invention is mounted on the element to be earthed, the solder 20 connects sleeve 10 and threaded insert 1, a permanent and firm connection between the two different materials is thus ensured without additional welding.
  • Threaded insert 1 and sleeve 10 are made so that they can already be assembled as a pre-assembly of the mass cam on the material to be grounded.
  • the invention is not limited to the above-mentioned features, but further embodiments are conceivable. So further materials of sleeve and threaded insert are conceivable, for example, simple structural steel for the sleeve and stainless steel 1.4571 for the threaded insert. It is also possible to make the sleeve not round, but star-shaped. The resulting, longer weld reliably conductive connections are possible, which are more durable. LIST OF REFERENCE NUMBERS
