    摘要: A telephone handset comprises elongated complementary upper and lower housing members that mate at their perimeters to form a hollow handset housing. The lower housing member includes a pair of spaced apart transducer receiving cavities, each being shaped to receive a cylindrical transducer surrounded by a flexible tubular gasket and form an acoustic seal therewith. Each gasket includes flanges around its circumference that project radially outward and in a direction opposite to the direction of insertion of the transducer/gasket assembly into its associated cavity. Such construction provides adequate mechanical retention between the transducer and the lower housing member and avoids the need for additional retaining hardware. The upper housing is joined to the lower housing using one or more pairs of side-mounted, interlocking hooks and latches. The upper housing further includes ribs, molded therein and positioned to maintain the transducers in place when it is joined with the lower housing.

    摘要: An anvil for a press for assembling a fastener to a plate having an aperture. The press includes a ram assembly for pressing the fastener into the plate aperture. The anvil includes a housing and a pin disposed in the housing. The pin is slidable between an extended position, partially extending outwardly of the housing and is adapted to extend through the plate aperture. The pin moves to a retracted position disposed within the housing for contact with the bottom surface of the plate. The anvil further includes a collar disposed in the housing and concentrically disposed around the pin. The collar includes a plurality of spaced apart collar sections, each collar section having a bottom flange retained by the housing and a top flange. The collar sections are movable between an expanded position when the pin is in the extended position, and a collapsed position when the pin is in the retracted position within the housing. The collar sections top flanges engage the pin top surface in the pin retracted position to form a barrier below the plate aperture to prevent fastener extruded material from protruding on the plate bottom surface after the fastener is inserted into the plate.

    摘要: A tubular piece part (10) is tested to determine the rupture strength of the part when subject to lateral expansion (F) with respect to a bore (11) of the part. In one example, a tubular segmented collet (21) is placed in the bore of the part, and a tapered pin (23) is forced a predetermined distance into the collet (X) so as to expand the collet and part radially outward by a predetermined amount. The peak force required to so expand the collet is measured (57) so as to provide an indication of the rupture strength of the part, and particularly of the weld strength of a molded plastic tube having a radial weld line (W). In particular, this method provides an indication of the likelihood that the part will fail prematurely in the field, after subsequent assembly of the part with an insert member (17) that is force fit into the bore.
