A connection between at least a first component A and a second component B with an attachment arrangement with tolerance compensation between the first component A and the second component B. The entire connection is fixated via a blind rivet which is not non-destructively detachable while a compensating sleeve spans a distance between the first component A and the second component B.

A semiconductor package is disclosed. The semiconductor package comprises: a metal shim, a package substrate attached onto a front side of the metal shim, wherein the package substrate comprises an opening that passes therethough; one or more electronic components mounted on the package substrate; an encapsulant layer partially formed on the package substrate to expose a region of the package substrate and the opening of the package substrate, wherein the encapsulant layer encapsulates the one or more electronic components on the package substrate; a first connector mounted in the exposed region of the package substrate; a second connector mounted in the encapsulant layer and on the package substrate; and a magnet mounted in the opening of the package substrate and extending from the metal shim through the package substrate and the encapsulant layer.

A multipart adjustment element for a tolerance compensation arrangement for automatically compensating for tolerances in the spacing between a first and a second component. The adjustment element comprises a bush, a dragging element, a contact disc, and a securing sleeve. The bush has a bore, an outer thread with a first direction, and a step. The dragging element comprises at least one spring arm protruding radially inwards, wherein a first axial end of the dragging element is arranged on the step in the threaded bush. The contact disc is arranged adjacently to the first axial end of the threaded bush and has a through-opening. The securing sleeve likewise has a through-opening and is arranged at least partly in the bore of the threaded bush with a press-fit connection in order to securely connect the contact disc, the threaded bush, and the dragging element together.

Self-forming thread blind fasteners and methods for fastening are provided. The self-forming thread blind fastener comprises a sleeve and a pin. The sleeve comprises a first sleeve end, a second sleeve end, an elongate portion, and an inner wall defining a bore. The pin is configured to be at least partially received by the bore. The pin comprises a first pin end, a second pin end, a pin head portion, an at least partially threaded portion, a shank intermediate, and a driving portion. The at least partially threaded portion is configured to form threads on at least a portion of the inner wall of the sleeve. The driving portion is configured to receive a torque to rotate the pin within the sleeve and thereby axially compress and deform the sleeve and form the threads on the at least a portion of the inner wall of the sleeve.

A fastener including a sleeve having an elongated portion, a head with a bearing surface, and an internal threaded portion, a core bolt disposed within the sleeve and having a head and a shank portion having an external threaded portion engageable threadedly with the threaded portion of the sleeve. An insert is disposed within the sleeve and surrounds a portion of the core bolt. A seal element is attached to the sleeve and juxtaposed with the bearing surface of the head of the sleeve. The fastener is adapted to be installed in a structure. The electrical contact of the fastener reduces the potential difference between it and the structure, which provides a direct path for continuous propagation of electromagnetic waves, reducing electromagnetic wave scattering and minimizing the electromagnetic signature.

A blind rivet nut for introduction into an opening of one or more components, comprising a hollow shank having a front end for placing an assembly tool and a rear end for introduction into and/or passage through the opening. The shank has a deformation portion with a first wall thickness (t1) and an adjacent threaded portion with a second wall thickness (t2) that is greater than the first wall thickness (t1), the threaded portion having an internal screw thread. The shank has a predetermined breaking point in an area of the threaded portion and/or the deformation portion, the predetermined breaking point being designed such in terms of its position and orientation that the threaded portion dips into the deformation portion when the shank is tensioned in the axial direction after breaking at the predetermined breaking point.

In order to improve fastening precision, the present disclosure provides a projection-type blind hybrid fastening apparatus for fastening a first frame part which has an upper open side and through which a first coupling hole is formed and a second frame part through which a second coupling hole is formed, the apparatus including a projection fastening part including a head portion that extends outward from an upper rim surface of the first coupling hole and an extension support portion which extends upward from an inner end of the head portion and through which a first through-hole is formed on an inner circumference thereof, a blind fastening part which extends integrally upward from the extension support portion and through which a second through-hole communicating with the first through-hole is formed on an inner circumference thereof, and a tool coupling part which extends integrally upward from the blind fastening part and through which a third through-hole communicating with the second through-hole is formed on an inner circumference thereof.

An installation tool for a fastener of the pull screw type, comprising a breakable gripping element includes a body, a first sleeve movable axially and rotationally in the body that can drive the gripping element, a second sleeve movable axially in the body and immovable in rotation, and a driving device provided with a turning shaft.

The shaft comprises a first free wheel for driving the first sleeve in rotation, a second free wheel, and a driving element positioned coaxially around the second free wheel. The driving element cooperates using a helical link with the second sleeve. The first free wheel drives the first sleeve in rotation in a first rotation direction of the shaft. The second free wheel brings the driving element in rotation in a second rotation direction of the shaft to move the second sleeve axially, allowing full setting in a single operating sequence.

A rivet fastener assembly is configured to securely clamp together one or more components. The rivet fastener assembly includes a pin and a rivet body having a collar and a column extending from the collar. The rivet body further includes a collar stop configured to provide a positive locating feature for the pin once assembled.

A blind tacking rivet includes a stem and a sleeve. The stem includes a body and a stem head. The stem head is removable from the body. The stem head deforms a portion of the sleeve during removal of the stem head. The stem head may be discarded or may be embedded within the sleeve.
