| Drilled a 3mm hole instead of a 2mm for the locking pins as this is easier to work with for this prototype test. The adjusted screw driver (v shape) was used to separate the pins when fitted. |
|
| Just showing you the standard length of a earth pin in a standard 3 pin plug. |
|
| Also 3mm hole all the way down the earth pin to meet the horizontal 3mm hole (should be a horizontal 2mm hole) |
 |
| Showing the standard thickness of the earth pin |
 |
| The above picture is showing how much the plug can be taken out of the socket before the locking pin would stop the plug being removed further. |
 |
| The CAD drawings where changed as this is too much and requires the 2mm locking pins to be closer to the plugs bottom. 3D CAD drawings here |
 |
| Showing you the plug from front elevation, this 3mm hole was too close to the end of the earth pin on this first test. |
 |
| The above image shows you a standard single switched MEM rear socket |
 |
| MEM socket with the earth pin connection removed |
 |
| The red dot in the above picture shows where the rubber locking pin locates. The other rubber locking pin will stay inside the earth pin due to the brass earth connection is in the way, so the locking plug will only use one of the two 2mm diameter rubber locking pins to lock the plug into the socket. |
 |
| This picture is showing the earth pin into the MEM socket, unfortunately you can't see the rubber locking pin, but the test was successful with and without the earth connection. |
