(54) Title

Two-shot tube retention pocket tube clamp, mold and process

(57) Abstract

A first shot body member includes a pair of side walls, a semi-circular sleeve positioned between the pair of side walls to define a portion of a longitudinal pocket, and a pair of deflecting wings. Each deflecting wing is coupled to one of the side walls at a corner. A second shot isolation member of an elastically resilient second material is bonded to portions of an interior surface of the longitudinal pocket defined by each of: the semi-circular sleeve, each of the pair of side walls, each of the pair of corners, and each of the pair of wings. Mold members can include supporting surfaces to support interior and exterior portions of the wing during the second shot molding operation, while leaving an exposed interior bonding surface that defines a portion of the second shot molding cavity. Related methods are further disclosed.

Description

The present disclosure relates to fasteners used in automobile vehicle service to retain and route tubing and electrical wiring, and related molds and molding processes.

This section provides background information related to the present disclosure which is not necessarily prior art.

Clips and fasteners are known which are used to retain tubular shaped objects such as metal or rubber tubing used for hydraulic, vacuum, fuel and similar services, and electrical wires, cables, and wire bundles in automobile vehicles. Vibration and sound transmitted from an upstream or downstream component of the vehicle can be transferred through the fastener to the body panel to which the fastener is connected, thereby inducing unwanted noise. Resilient material inserts can be provided using a two-shot molding process.

Known designs can provide less than optimal wing flexibility to facilitate maximum opening and centering capability during insertion of the tubular objects. In addition, known two-shot molds and processes can provide less than optimal support of the first shot component during the molding of the resilient second shot component.

This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

In accordance with a first aspect of the present disclosure, a tube retention fastener includes a body of a first polymeric material. The body includes a pair of side walls, a semi-circular sleeve positioned between the pair of side walls to define a portion of a longitudinal pocket, and a pair of deflecting wings.
