Abstract

Methods and apparatus are provided for cleaning jacks in portable electronic components. In one embodiment of the present invention, an adaptor plug is designed having a hollow shaft and the end of the plug is designed with holes that communication with the hollow shaft. The plug can be inserted into a jack, which can operate to open one or more switches within the jack, thereby freeing any debris that may have accumulated under the switches. Compressed air can then be applied down the hollow shaft and out the holes in the plug to displace the debris and clean the jack. In another embodiment, the end of the plug can be constructed such that it rotates about an axis to increase the likelihood that the jack will be cleaned.

Claims

1. A method for cleaning a jack comprising a switch, the method comprising:

inserting an adaptor plug into the jack, wherein the inserting causes the switch to change from a closed state of the switch to an open state of the switch; and

once the adaptor plug has been inserted into the jack and once the switch has changed from the closed state to the open state, forcing a gas successively through an internal hollow channel within the adaptor plug and through a hole in the adaptor plug that is in communication with both the internal hollow channel and the outside of the adaptor plug, wherein the forced gas removes debris that was trapped under the switch when the switch was in the closed state.

2. The method of claim 1, wherein the forcing comprises blowing the gas through an open end of the internal hollow channel and towards the hole, and wherein the blown gas exits the internal hollow channel through the hole for removing the debris from the jack along the outside of the adaptor plug.

3. The method of claim 2, wherein a feature along the outer surface of the adaptor plug directs the debris as the blown gas removes the debris along the outside of the adaptor plug.

4. The method of claim 1, further comprising coupling a compressed gas source to an open end of the internal hollow channel, wherein the forcing comprises blowing the gas from the compressed gas source through the open end of the internal hollow channel and towards the hole.

5. The method of claim 4, wherein the blown gas exits the internal hollow channel through the hole for removing the debris from the jack along the outside of the adaptor plug.

6. The method of claim 1, wherein the forcing comprises drawing the gas from outside the adaptor plug, through the hole, and then into the internal hollow channel, and wherein the drawn gas exits the internal hollow channel through an open end of the internal hollow channel for removing the debris from the jack along the inside of the adaptor plug.

7. The method of claim 1, further comprising coupling a vacuum to an open end of the internal hollow channel, wherein the forcing comprises drawing the gas from outside the adaptor plug, through the hole, into the internal hollow channel, and then through the open end of the internal hollow channel and into the vacuum.

8. The method of claim 7, wherein the drawn gas exits the internal hollow channel through the open end of the internal hollow channel for removing the debris from the jack along the inside of the adaptor plug.

9. The method of claim 1, wherein the forcing causes a plug portion of the adaptor plug to rotate with respect to a shaft portion of the adaptor plug, wherein the hole is in the plug portion, and wherein at least a portion of the internal hollow channel is within the shaft portion.

10. The method of claim 9, wherein the forcing causes the plug portion to rotate about an axis of the internal hollow channel.

11. The method of claim 1, further comprising at least partially removing the adaptor plug from the jack during the forcing.

12. The method of claim 1, wherein the forcing causes at least a portion of the adaptor plug to rotate within the jack.

13. The method of claim 1, further comprising rotating at least a portion of the adaptor plug within the jack during the forcing.

14. The method of claim 1, wherein the forcing comprises forcing the gas in distinct bursts.

15. The method of claim 1, wherein the gas comprises compressed air.

16. The method of claim 1, wherein the jack is configured to receive a 3.5 millimeter plug.

17. The method of claim 1, further comprising at least partially removing the adaptor plug from the jack, wherein the removing causes the switch to change from the open state to the closed state.
