The Fall of Adapters

This morning the phone was off. The adapter fell from the plug. Again. Although it was held by a rubber band i put around the plug cover for that purpose. The adapter was hanging in the rubber band with the two contacts slightly off the plug. Then i went to Fry's to buy stronger rubber bands. And in the Office Supplies department here they were. In a bag about 8x6 inches for $1.65 they were about 500 rubber bands of all sizes. And then i told myself. What to do with 500 rubber bands? And i gave up. And said to myself again. The plug-in AC adapters are not supposed to fall from the plug. I'm gone figure out something. The plugs where i live are probably @30 years old but in fair condition. Everything else stays in there. The adapter for the modem never fell. And then i realized, for the first time in my life. The heavy adapters with a transformer inside are not supposed to be the plug in type. They should have a cord and sit somewhere not in the plug. They made a big mistake when they approved for sale something like that. The plugs were not designed to hold such heavy weight. I weighed the phone adapter. It's 100 grams. Almost 1/4 pound. And it only has 2 contacts. One regular plug with two contacts is about 10 grams. When they first designed the plugs for homes i'm sure they didn't have in mind something like that. And the two active contacts are not round like the ground one but flat with the flat side in the vertical rotation plan and they turn around under weight and fall when you use an adapter with only two contacts. If those adapters would use a third contact not necessarily for ground but just for mechanical stability, it would be better. But where were the regulators in this case?
