Abstract: A screw for an electrically contacting connection includes a screw head and a thread having a thread profile with a first thread flank facing the screw head and a second thread flank facing away from the screw head. The first thread flank is continuously curved from a radially inner bottom region to a radially outer run-out region in such a way that first angles between the center axis and local tangents, which lie on the first thread flank and intersect the center axis of the screw, increase radially outward along this direction. The second thread flank and the center axis include a second angle, which lies below the maximum first angle, in the opposite direction of the first angle. The run-out region continuously connects the first thread flank and the second thread flank to one another and is completely rounded.

Abstract: A mobile device and a method for the placement of a group of pin-type fasteners so as to form at least one seam field for purposes of connecting large components in aircraft construction, such as fuselage shells and fuselage sections, for purposes of connecting large components in ship construction, in rail vehicle construction, in building construction, and similar construction environments.

Abstract: A contact sealing ring includes an electrically conductive annular disc which has a central through-opening, a first electrically conductive contact formation which protrudes from a first side of the annular disc, and a second electrically conductive contact formation which protrudes from a second side, opposite the first side, of the annular disc.

Abstract: The present disclosure relates to an electrically conductive pin connection, including a first electrically conductive contact component which has a first hole, a second electrically conductive contact component which is in contact with the first electrically conductive contact component and which has a second hole, a connecting pin which has a pin head and which is guided through the first and second holes for connecting the first electrically conductive contact component and the second electrically conductive contact component, and a plurality of electrically conductive wires which are arranged in the holes between the edges of the holes and the connecting pin, wherein the electrically conductive wires are bent in such a way that they are clamped between the pin head of the connecting pin and the first electrically conductive contact component.

Abstract: A holding device produces a retaining pressure on a contoured airplane component (40) for holding the component in place when work is performed on the component. For this purpose the holding device (10) comprises a support (11) and at least one holding element (16) connected to the support (11) and projecting from the support (11) for contacting the contoured airplane component (40) in a holding zone. A spacing between a contact area of the holding element (16) and the support (11) is adjustable in accordance with the contour of the airplane component (40) in the holding zone. The adjustment of the position of the holding element relative to the support (11) moves the holding element (16) more or less against the surface contour so that the holding force is applied exactly where needed on the holding zone. A plurality of holding elements can be advanced toward the surface contour to variable extents so that all contact areas together conform to the surface contour.

Abstract: An electrical connection element for connecting supply lines, in particular in an aircraft. The connection element comprises a connector socket and a connector that can be inserted into the connector socket, wherein the connector is axially rotatable in the connector socket, as a result of which a non-positive connection between the connector and the connector socket is established. An independent solution provides for the connection element to be made in a single piece and to comprise two clamping receptacles for the ends of the supply lines to be connected.

Abstract: A holding device is designed to compensate for the weight of a tool using a non-vertical length of an elastic rope. The elastic rope may be redirected using a pulley mounted to a carrier that is mounted to a support structure. The user is able to use the tool without supporting the entire weight of the tool during use.

Abstract: The drilling of a hole through at least two structural components in alignment with a predrilled hole or marked location in one of the structural components is facilitated by a clamping mechanism that has a bail with two legs. One leg carries a first clamping section with a guide channel for a centering pin or a drill bit. When the centering pin has served its purpose it is removed from the guide channel which then guides the drill bit. The other leg carries a second clamping section opposite the first clamping section. The second clamping section has a pressure bushing drivable by a clamping drive for clamping the second structural component against the first structural component for drilling a hole through all structural components including through a predrilled hole or for simultaneously drilling all structural components at the marked location. The pressure bushing has a hollow free end forming a cavity.

Abstract: In order to facilitate and make more ergonomic the drilling of a multitude of holes in workpieces, particularly in the assembly of large scale components, such as an aircraft body, the power drill is docked to a support by an attachment which engages and locks onto a guide bushing or bore in the support. The attachment assures that the drill bit is precisely axially aligned with a hole to be drilled. The feed advance is performed by a leveraged action controlled by the operator. The leverage can be provided, for example by a Bowden pull cable. The attachment reduces the exertion to be made by the operator, thereby avoiding ergonomically unsatisfactory work positions.

Abstract: The field relates to a lockbolt for joining at least two component layers. The field furthermore relates to a method for producing a lockbolt connection between at least two component layers, as well as to an aircraft in which at least two component layers are joined with the lockbolt. The lockbolt includes a bolt shaft with a bolt head, as well as a tear-off shaft that is connected to the bolt shaft at a predetermined breaking point. An elastic clamping element provided on the tear-off shaft serves to fix the lockbolt in a through-hole.
