Grounding Cord with Eyelet
The idea is to ground the equipment powered by continuous low voltage DC – Internet box, telephone with wired handset, ECO DECT phone (often placed on the desktop), various devices on charge, Switch, Hub, fibre optic converter/RJ45…. in short, when the grounding USB cord solution does not allow it (no built-in USB port or metal USB not connected to the device’s metal frame).
Images are better than words, see the following examples :
The socket (left part) is connected to the ground connector of the electrical wall outlet. The eyelet (right side) makes contact with the ground wire of the device low voltage power supply to the electric ground.
1// Example to connect the internet BOX to the electric ground
Cordless : 290 V/m
With cord : 1,2 V/m
2// Example to connect a DECT phone to the electric ground
Cordless : 107 V/m
With cord : 12,3 V/m
3// Example to connect a device to the electric ground
Cordless : 325 V/m
With cord : 0,9 V/m
Manufacturing
The inner diameter must be 5 to 6 mm
