Abstract
The present invention relates to a shear fastener for an electrical connector. The fastener includes a head from which a threaded shaft extends. The head defines a pair of polygonal portions separated by a recess so that an endmost one of the polygonal portions can be separated from the fastener by shearing as the fastener is tightened within the connector. Separation of opposite flats of the endmost polygonal portion is different (e.g. greater) than separation of opposite flats of the other polygonal portion. In one embodiment, the engagement socket of a pneumatic wrench can slip over the polygonal portions and rotate through 360° when rapidly tightening the fastener whilst engaging with the endmost polygonal portion, without engaging with the other polygonal portion.
Claims19
A shear fastener for an electrical connector, the fastener including a head from which a threaded shaft extends, the head defining a pair of polygonal portions separated by a recess so that an endmost one of the polygonal portions can be separated from the fastener by shearing as the fastener is tightened within the connector, separation of opposite flats of the endmost polygonal portion being different than separation of opposite flats of the other polygonal portion.
A shear fastener for an electrical connector, the fastener including a head from which a threaded shaft extends, the head defining a pair of polygonal portions separated by a recess so that an endmost one of the polygonal portions can be separated from the fastener by shearing as the fastener is tightened within the connector, separation of opposite corners of the endmost polygonal portion being different than separation of opposite corners of the other polygonal portion.
A shear fastener for an electrical connector, the elongate fastener including a head from which a shaft extends, the head defining a pair of portions separated by a recess so that an endmost one of the portions can be separated from the fastener by shearing as the fastener is tightened within the connector, the endmost portion having a cross sectional area transverse to the fastener different than the other portion.
