Abstract

A design is needed for a miniaturized waterproof connector for use within an electronics device, such as a headset for a cochlear implant system or a hearing aid. The novel contribution is a design for a miniaturised waterproof connector to use within an electronics device, such as a headset for a cochlear implant system or a hearing aid. The connector consists of two parts: a plug and a socket. The key aspect of the invention is the integration of the retention and sealing functions into one feature. This achieves both miniaturisation and sealing.

Miniaturised Waterproof Connector

Abstract

Problem Addressed 

A design is needed for a miniaturized waterproof connector for use within an electronics device, such as a headset for a cochlear implant system or a hearing aid.

Novelty Statement

The novel contribution is a design for a miniaturised waterproof connector to use within an electronics device, such as a headset for a cochlear implant system or a hearing aid.  The connector consists of two parts: a plug and a socket. 

The key aspect of the invention is the integration of the retention and sealing functions into one feature.  This achieves both miniaturisation and sealing.

To accomplish miniaturisation, the size of the final assembly is reduced by reducing the number of features necessary to create the connector.  Figure 1 shows a size comparison (excluding strain relief) of the existing BTE connector, which has separate sealing and retention features.  Note, in particular, the size difference of the socket; almost a 50% size reduction is achieved on certain dimensions.

To produce the desired sealing properties, the design utilizes an efficiently packaged soft-on-hard seal, which enables a more robust seal than was previously possible.  Current connectors are rated to IPX7 (still water, 1m, 30 minutes); however, testing of the miniaturised connector in simulated swimming environments (e.g., highly agitated water, 20cms, 2hrs) s...
