9 years agoPeter Dolding Seams like a really good idea but is a Really Bad Idea. Reply Normal cables hdmi, usb and network don't have the structual strengh to really hold being pulled, So are required to fail at plug to protect the integerity of the rest of the cable. You design there will see wire pull out of plug or the wire ruined in the cable. There are IP67 and higher rated cables out there. Bigger screw threaded section around the plug. Some of those have steel rope/wire inside them so you can hang 100+ kg off them. Basically secure hold in place requires better than your stock cables. Issue here I have done a cablers course for network cabling and other items inside buildings. Rule of you have a port requiring to stay put you add a mounting plate holding IP67 or better sockets and plugs then make the cable to higher spec. Of course a compact lock in place plug and socket style would be good. You cannot do it as a addon device to existing plugs because exsiting plugs and cables connected to them are only rated to a particular level of force(the ammount required to remove plug from socket). You need to change design of plug and require a higher cable rating..
