Embodiment Construction

[0021] Embodiments of the present invention provide a washer configured for securing a clamp assembly. The fastening clamp assembly may include a head connected to the annular flange by a neck. In at least one embodiment, a central beam extends from the flange opposite the head. Opposite deflectable fixed wings are connected to the central beam, for example close to the lead-in nose.

[0022] The gasket may be formed from an elastomeric material such as Santoprene, rubber. The washer is configured to be secured to the flange or umbrella of the fastening clamp assembly. The gasket may include a honeycomb upper surface that provides strength and stiffness while also reducing material and weight. In this way, the gasket is strong and relatively lightweight.

[0023] In at least one embodiment, the gasket is secured under the flange and has clamp sealing interfaces (eg, points, ridges, or other such contact areas) that abut the underside of the flange. Additionally, the gaske...

Abstract

A washer (100) is configured to be secured underneath a flange of a fastening clip assembly (200). The washer includes an annular support ring defining a central channel and having a first surface anda second surface that is opposite from the first surface. The first surface is configured to abut into and sealingly engage the flange at two or more locations. An inner sealing rim (120) extends from the second surface proximate to the central channel. The inner sealing rim is configured to sealingly engage a component at a first component sealing interface. An outer sealing rim (122) extends from the second surface and is outwardly separated from the inner sealing rim by a gap (126). The outer sealing rim is configured to sealingly engage the component at a second component sealing interface.

Description

[0001] related application [0002] This application is related to and claims the benefit of priority to U.S. Provisional Patent Application 62 / 261,403, filed December 1, 2015, entitled "Gasket for Fastening Clamp Assemblies," which is incorporated herein by reference in its entirety. technical field [0003] Embodiments of the present invention generally relate to a fastening clamp assembly having a washer. Background technique [0004] Various components include panels or objects connected to each other. Automotive components include, for example, various panels and structures that are connected to other panels or structures, or to the vehicle frame itself. Specifically, snap-fit ​​assemblies can be used to join components together. Additionally, the fastener may be pre-assembled with one of the parts or panels, while the second part or panel is attached to the pre-assembly during final assembly. When joining relatively large components together, multiple fasteners may ...
