Abstract: Two parts (120, 160) can be mated and secured from relative movement in three different orthogonal directions or planes by the use of a novel, two piece, plastic fastener structure. The snap fastener has an integral interlocking tab (170) that serves to constrain the movement in a third direction or plane. The snap fastener additionally consists of an operative component (110) and a securing component (150). The operative component has a resilient member (112) that deforms to receive a catch member (152) on the securing component when the operative component and the securing component are snapped or mated together. One of the two components contains an opening (180), while the other contains a body portion shaped more or less like a tab or tongue which is capable of being inserted within the opening when the two components are mated. When so inserted, the relative movement of the two components is restricted in three directions, without the use of a remotely located securing means.

Abstract: A cover for a housing is maintained in a fixed position with respect to the housing by a latch arrangement that has at least one edge surface disposed along one edge of a flange which engages a mating surface on the housing when the cover is assembled with the housing. The other side of the flange is integrally formed with an elongated beam that is attached to the cover structure. The elongated beam is torsionally loaded upon assembly of the cover with the housing, and provides a bias force on the edge surface of the flange to maintain the forcible engagement of the edge surface with a mating surface of the housing. The latch arrangement combines the cost effectiveness and space efficiency characteristics of plastic latch designs with the durability, dependability and tactile qualities of mechanical spring arrangements.

Abstract: A snap-latch mechanism for releasably connecting two components comprises a male latch member extending from a first component and a female latch frame disposed on a second component. The latch frame defines a passageway through which the latch member is inserted, and the latch member undergoes a torsional deflection as it passes therethrough to achieve locking engagement with the latch frame. The torsional deflection is caused by two oppositely inclined ramp surfaces disposed on the interior of the lock frame to apply a camming action and rotate an enlarged head portion of the latch member as it passes through the passageway. When the head portion has passed completely through the frame, it is released from the ramp surfaces and the latch member returns to its undeformed configuration and is latchingly engaged with the latch frame.
