Apple Invents a Protective Connector Port Cover using Magnets

1. Apple Invents a Protective Connector Port Cover using Magnets
On January 17, 2013, the US Patent & Trademark Office published a patent application from Apple titled "Magnetically Activated Connector Port Cover" which is an invention designed to keep crumbs, pocket lint and fluids from entering your devices via their ports. Apple provides a simple yet creative solution.

 

Apple's Patent Background

 

Electronic devices typically have one or more locations to provide access to external connectors, such as audio connectors, data connectors, power connectors and the like. These access points (sometimes referred to as "connector ports") also allow for dust and other debris to collect. Debris can disrupt the connection between electronic devices and external connectors.

 

Historically, some electronic devices included a connector port cover to prevent debris interference at the access location for external connectors. These covers sealed the connector port closed when not in use. Some connector port covers are cumbersome to operate between open and closed positions and may be easily breakable because space constraints led to less robust systems. In some instances, these factors have led to accidental or purposeful removal of the connector cover.

 

Some electronic devices have abandoned the inclusion of connector port covers for the aforementioned reasons. As a result, longer wiping distances may be implemented for electronic connectors to partly cope with the debris issues. However, this solution is not complete and requires a deeper connector. Consequently, connections can still be disrupted and scarce internal device space or other resources may be allocated to help remedy the debris issues. Hence, a need for connector port covers still exist, but the usefulness of future connector covers will depend on the extent to which the historical pitfalls can be overcome.

 

Apple's Magnetically Activated Connector Port Cover

 

In view of the shortcomings in currently available port covers as described above, Apple's invention provides a magnetically activated connector port cover to provide access for a corresponding connector to mate with a receptacle connector within an electronic media device and to seal the connector port cover closed when the connector is not presently proximate to or intending to mate with the electronic media.

 

In one embodiment, a connector port according to Apple's invention includes an opening having a door movable between a closed position where the opening is sealed and an open position for receiving a corresponding connector plug through the opening. An actuator is operatively coupled to bias the door in the closed position with a bias force. A magnetically responsive element that, when the corresponding connector plug is proximate to the opening in the connector port, is responsive to a magnetic field to provide a second force greater than the bias force that moves the door to the open position.

 

In another embodiment, a connector port according to the present invention includes an opening having a door movable between a closed position where the opening is sealed and an open position for receiving a corresponding connector plug through the opening. The connector port also includes an actuator for moving the door between its positions and a magnetically responsive element that biases the actuator when the corresponding connector plug is proximate to the opening in the connector port.

 

In yet another embodiment, a connector port according to the present invention includes an opening having a door movable between a closed position where the opening is sealed and an open position for receiving a corresponding connector plug through the opening. The connector port also includes a sensor that detects when the connector plug is proximate to the opening in the connector port and one or more electromagnets that bias the door in a sealed position and, in response to the sensor detecting that the connector plug is proximate to the opening, move the door to an open position allowing the connector plug to be inserted into the opening in the connector port.

 

Apple states that their new invention could apply to many types of devices including the following: Apple's iPod devices, portable video players (e.g., portable DVD players), Apple's iPhone devices, video cameras, digital still cameras, projection systems (e.g., holographic projection systems), gaming systems, PDAs, desktop computers, as well as Apple's iPad devices.

 

2A. Overview of Apple's Newly Proposed Connector Port Cover Invention

 

In the closed position, Apple states that port cover 325 covers opening 305 thereby preventing or limiting intrusion of solid particles such as dirt, crumbs, dust, lint and other substances which may otherwise enter into cavity 302 and be hard to clean or remove from the cavity. Over time, the accumulation of such particles may create potential for interference of or damage to the interface between connector 315 and connector 320.

 

Potential for fluid penetration may originate from wet or moist conditions including snow, rain, fog, humidity or liquid contact resulting from spills, splashing, spraying or other wetting events. Fluid penetration can damage or adversely affect the components at the connection interface and other components within electronic media device and/or or the connector.

 

Apple's patent FIG. 3b shown below is an angled front view or three-dimensional view of connector port cover 325 operatively coupled to a motor element 333 actuator instead of a spring loaded hinge. Motor element 333 can be, for example, a SQUIGGLE motor that is controlled or switched on/off by a sensor.

Apple's patent FIG. 7 shown above shows a side or top view of an illustrative connector port cover which may be likened, for example, to a sliding door.

 

And finally, Apple's patent FIG. 9 shows a side or top view of an alternative design of a connector port cover that may function in a manner similar to a sectional garage door, wherein section elements 965, connected by hinge elements 970, fold as connector port cover 925 opens or closes.
