Wire thread insert consisting of a body with a plurality of helically wound windings, in which the plurality of helically wound windings comprises a first end winding and a second end winding which define the body at opposite axial ends, the first end winding has a first integral form-fitting means in a first end section and the second end winding has a second integral form-fitting means in a second end section, so that in an installed state of the wire thread insert a form-fit rotation-inhibiting connection with an adjacent component structure can be produced via the first and the second integral form-fitting means respectively.

Wire thread insert

A component has a base bushing, which has a first axial end and an opposite second axial end and a first inner diameter, wherein the base bushing is equipped with a first internal thread with a first thread direction, and has a fastening bushing, which has a third axial end and an opposite fourth axial end and a second inner diameter. The fastening bushing is equipped with a second internal thread with a second thread direction which is opposite to the first thread direction, wherein the second inner diameter is smaller than the first inner diameter and the base bushing and the fastening bushing are separate elements and are arranged coaxially with respect to one another in the component. Alternatively, the base bushing and the fastening bushing are formed as a single piece.

Component with tolerance compensation function

A fastening insert made of plastic with a T-shaped configuration consisting of an insert disc and a hollow cylindrical shaft fastened to the insert disc. The insert disc has a plurality of passage openings arranged off-center, at least one of which has an edge projection extending circumferentially continuously or circumferentially in sections, which is formed as toothing and extends on one side or both sides beyond the respective fastening side of the insert disc. This toothing ensures an additional form-fit connection or fixation of the fastening insert in a preferably fiber-reinforced composite material.

Fastening insert for a component made of plastic, foam or composite material

A fastening element consisting of a cage element with a nut arranged therein that is held by a fastening flange in the cage element. The cage element has a wall element which can be moved in an axial direction and shields the seat area of the cage element against the penetration of adhesive while mounting the fastening element on a component surface.

Fastening element

A metal casting method and a plastic injection molding method in which an insert is molded in molten material such that no molten material enters the interior of the insert. The usage of a wire thread insert as insert has the advantage that for example in an aluminum cast part thread holes can be produced already as part of the casting process. For this purpose, the casting mold, the insert, as well as the casting method are described.

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

Connection between two components made of reinforced plastic and method for the production thereof

A moldable wire thread insert for reinforcing a screw-in opening of a component has the following characteristics: a cylindrical spiral made of a helically, wound wire, the neighboring coils of which are arranged such that a closed cylindrical spiral wall is present, while at least one end of the cylindrical spirals has a fastening flange, which extends radially outwards over the cylindrical spiral wall and with which the wire thread insert is anchorable in the component and/or one end of the cylindrical spiral is designed in a planar manner in order to form an even axial front surface of the cylindrical spiral.

A friction welding method for fastening a connection bushing, such as a threaded bushing for example, in a housing. In order to improve the quality of the connection, the connection bushing is attached to the housing using a friction welding element. The friction welding element consists of the connection bushing, on which a friction welding shell with a radially outer friction welding contour is formed or molded. Connecting and sealing portions are produced between the friction welding element and the housing during the friction welding process by means of a special design of the friction welding contour.

Friction welding element, and a method for connecting the friction welding element to a housing

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element () having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

The present disclosure describes a connection insert, in particular a threaded insert, which is embeddable into a formed plastic component. This connection insert comprises a cylindrical main body having a radially outer side, a radially inner side as well as a first and a second axial end, at least one circumferential collar arranged at the radially outer side of the main body which has the largest outer diameter compared to the remaining main body and which is arranged spaced with respect to the first and the second axial end of the main body, and a radially protruding structure arranged at the radially outer side of the main body.

Connecting insert and an embedding method and a production method therefor
