Method for a three-port audio connector with integrated switches for plug detection

Disclosed is a method for a three-port audio connector with integrated switches for plug detection. Benefits include improved functionality.

Background

Electrical requirements of the next-generation audio solution include providing sufficient electrical switching. No parts are conventionally available with the required switch mechanism in a three-stack device. In addition, the mechanical dimensions of available three-stack devices without switch mechanisms do not fit in the required form factors.

Conventionally, each port in the triple-stack audio connector has shunt springs instead of a mechanical switch. This solution renders the current jacks unable to detect when a plug has been inserted into the jack (see Figure 1).

General description

The disclosed method is a three port, stacked audio connector with a switch integrated into each port that enables the connector to detect when a plug is inserted. The method includes a mechanical design that meets the requirements of small form factors. The ground and contact springs are the same as in the conventional solution.

         The key elements of the method include:

•         Three audio ports are stacked one over the other.

•         Each port has a mechanical switch that is triggered when a plug is inserted.

•         All elements are integrated into the same housing.

Advantages

         The disclosed method provides advantages, including:

•         Improved functionality due to prov...
