Feedthrough connector for hermetically sealed electronic devices

Abstract

The present disclosure relates to an apparatus that includes an electrical connector that is coupled to a housing and that extends through a feedthrough aperture in the housing. The electrical connector has an electrically insulating base that has multiple layers of electrically insulating material with electrical traces extending between the multiple layers. The electrically insulating base also has a first portion disposed in the interior cavity, a second portion disposed external to the interior cavity, and a sealing portion disposed between the inwardly positioned portion and the outwardly positioned portion. The electrical connector also includes a first plurality of electrical leads that are disposed on the outwardly positioned portion of the electrically insulating base and a second plurality of electrical leads disposed on the inwardly positioned portion of the electrically isolating base material. Each of the electrical leads is electrically coupled to a corresponding lead.

Description

Technical field [0001] The present disclosure relates generally to electrical connectors for electronic devices, and more specifically to feed-through electrical connectors for hard disk drives. Background technique [0002] Hard disk drives usually use fast rotating disks or discs coated with magnetic materials to store and retrieve digital information. Digital information is transferred between the hard drive and the computing device through electrical connectors that form part of the hard drive. Conventional electrical connectors include non-feed-through connectors (for example, P2 connectors) and feed-through connectors. [0003] The feedthrough connector is defined by a plurality of electrical connections that extend from outside the housing of the electronic device, such as a hard disk drive, into the internal cavity of the electronic device. A part of the electrical connection outside the housing is electrically connected to the mating electrical connector of the computing...

Problems solved by technology

[0005] In addition, conventional feedthrough connectors often have large profiles (e.g., cross-sectional area), which adds difficulty and / or cost to achieving a sufficiently strong, reliable and properly sealed connection between the connector and the housing.

Also, many of the materials used in the manufacture of conventional feedthrough connectors are expensive, often requiring complex and expensive curing and handling procedures
