Embodiment Construction

[0019] A perspective view of a prior art snap tab fastener 10 for connecting two housing members 12 , 14 of an HVAC module is shown in FIG. 1 . FIG. 2 shows a cross-sectional view of the snap tab fastener 10 of FIG. 1 taken along section line 2-2. As best shown in FIG. 1 , extending from the first housing member 12 is a tongue 16 and a ring frame 22 adjacent to and positioned above the tongue 16 . Extending from the second housing member 14 are a first slot member 28 and a second slot member 30 defining a slot 32 therebetween. The slot 32 is oriented toward the first housing member 12 and is adapted to receive the tongue 16 extending from the first housing member 12 to form a substantially airtight seal. Extending from the first channel member 28 is a tab 52 including a locking member 55 having a ramped end 54 . The ramped end 54 is adapted to elastically deform the ring frame 22 to position the locking member 55 to lock the tab 52 to the ring frame 22 , thereby securing the...

Abstract

An in-groove snap fastener for securely connecting two housing members and for providing a substantially air tight seal is disclosed. The in-groove snap fastener includes a first groove member and a second groove member extending from a first housing member defining a groove therebetween. One of the groove members includes a raised surface oriented toward the other groove member and the other groove member defines an aperture. A tab member having an integral tongue portion and a locking portion extends from a second housing member in the direction of the groove. The tongue portion cooperates with the raised surface to provide an interference fit between the groove members forming a substantially airtight seal. The raised surface also urges the locking portion to cooperate with the aperture to secure the first housing member to the second housing member.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 227,897, filed July 23, 2009. [0003] technical field of invention [0004] The present invention relates to fasteners for connecting two components; more particularly, it relates to tongue and groove fasteners having snap-fit ​​features for connecting two housing components. Background of the invention [0005] A typical housing assembly is formed by joining together two or more housing members. Conventional tongue and groove fasteners are commonly used to join and seal two housing members in a simple and effective manner. In a typical tongue-and-groove fastener, the tongue is disposed along a joining surface of one housing member and the groove is disposed along a corresponding joining surface of the other housing member. The joining surfaces of the housing members are aligned and the tongues are then inserted into the slots to join and secure...
