Abstract

A connector card for hearing assistance devices is disclosed. The connector card can include any suitable number of contact arms (e.g., four) insert-molded into a thin card-style carrier. Further, the connector card can occupy less space within a hearing assistance device than is occupied by currently-available plug-style programming connectors, e.g., CS44 connectors. Also disclosed is a programming stick that can be plugged into the connector card. The programming stick can include a multi-layer assembly within one or more of the layers of the stick.

Connector Card for Hearing Assistance Devices Abstract A connector card for hearing assistance devices is disclosed. The connector card can include any suitable number of contact arms (e.g., four) insert-molded into a thin card-style carrier. Further, the connector card can occupy less space within a hearing assistance device than is occupied by currently-available plug-style programming connectors, e.g., CS44 connectors. Also disclosed is a programming stick that can be plugged into the connector card. The programming stick can include a multi-layer assembly within one or more of the layers of the stick. Problem to be solved

1. The preferred plug style programming connector is among the larger components in a hearing assistance device and therefor a major contributor to final size.

2. This connector’s space claim and access orientation drive the design and placement of most other internal components of the hearing assistance device.

3. Efficient placement of this component dictates that it be placed along the center plane of the device, which creates pockets of unusable space around it.

4. The Plug (CS44) also requires a second molded part to retain it in place. 5. Attempts to use a flex-based connector system have fallen short because:

a. Thin-walled connector housings are not structural enough to retain the flex; b. Styles that require a battery door are limited in placement freedom; and c. Due to connector design, the placement options only exist deep within the battery

compartment, which results in difficult-to-reach contacts and bent programming flexes.

Description

 The invention being proposed is connector card that includes four contact arms insert- molded into a thin card-style carrier.

 This connector card assembly features four cored-out windows of sufficient size to allow the use of common injection molding practices to locate and retain the four contacts during the molding cycle.

 The thickness of the card is sufficient to house the deflection of each arm.  The four exposed solder points can be oriented out the top, end, or...
