摘要： A method of forming pierce and clinch nuts by rolling a section having the desired cross-section, punching equally spaced bores through the central pilot portion and then punching configured openings through the central pilot portion having convex arcuate surfaces and eliminating sharp corners. The strip of interconnected self-attaching fasteners may be installed directly from the strip in a panel, fed in bulk or separate fasteners interconnected by frangible connectors. The resultant self-attaching nut includes a central pilot portion having a bore through the top face, integral flange portions extending from opposed sides and the pilot portion includes convex arcuate faces reducing or eliminating stress cracking and propagation of stress cracks.

摘要： An assembly line for continuously manufacturing fasteners from a rod with a groove for receiving a wire for retaining the fasteners in a strip includes a receiver for receiving the rod. A die press is arranged to receive the rod from the receiver and includes a piercing member for piercing an aperture in each fastener and a cutting member for cutting each fastener from the rod. A tapping member provides ribs to an inner wall of the aperture formed in the fastener by the piercing member. An inspector inspects the internal rib formed into the inner wall of the aperture disposed in the fastener verifying exactness of the aperture and the rib. A wire inserter inserts the wire into the groove forming a strip of connected fasteners. The inserter receives the fasteners sequentially from the inspector after verification of the exactness of the aperture disposed in each fastener.

摘要： The self-attaching female fastener of this invention includes a re-entrant groove having a V-shaped bottom wall including relatively inclined bottom faces of equal width having an arcuate apex centered beneath the restricted opening to the groove. A die drives a panel portion through the restricted groove opening against the bottom faces, driving the panel portion into the apex and inwardly beneath the inclined inner side wall and outwardly beneath the inclined outer side wall of the groove, resulting in a better installation and accommodating a wider range of panel thicknesses. The V-shaped bottom wall also centers and balances the rolls during the rolling process resulting in a more accurate cross-section of the fastener.

摘要： A self-attaching fastener installation head and feed mechanism including a spring-biased L-shaped feed pawl which feeds a first nut in the feed passage adjacent the plunger passage on the upstroke of the die press. The feed pawl is pivotally supported on a slide bracket which includes a roller in the longitudinal axis of the feed passage which is biased against a central cam surface on the base and the base is interconnected to the nose member by removable pins. A spring biased nut restrictor is pivotally supported on the nose member, simplifying removal of a nut strip from the head and the installation head is more rugged in design and has fewer parts, reducing costs.

摘要： A system is disclosed for installing fasteners in a panel and automatically sensing and compensating for certain error conditions which commonly arise in the installation process. The system includes monitoring the load exerted during the installation process and comparing the exerted load to nominal load values. If an error results between the two load values, appropriate corrective action is taken. If there is no corrective action which can be initiated to rectify the error condition, the system is halted.

摘要： An electrical grounding connector, electrical grounding connector assembly, and a method of attaching an electrical grounding connector and electrical grounding connector assembly to an electrically conductive panel is disclosed. The grounding connector assembly includes a grounding stud connector having a body portion disposed between, and integrally joining, a stud portion and a riveting portion. The body portion includes a flange extending generally radially from the body portion and the flange includes a panel engaging surface and a lug engaging surface. A protective nut is adapted to engage in substantially cover the stud portion of the grounding stud connector thereby protecting the stud portion from contaminants. Barbed elements are disclosed on various surfaces of the grounding connector thereby giving the grounding connector excellent electrically conductive properties when it is assembled to an electrically conductive panel. In a preferred embodiment, the grounding connector is preassembled with the protective nut, thereby allowing the assembly to be installed on an electrically conductive panel in one step. While the grounding connector and connector assembly is particularly suited for self-piercing applications, it may be used equally well in prepierced applications.
