On 510er Connector from Germany? Why not? What the American and English engineers can master the Germans of course too.
A replica was of course out of the question. Rather, in many places was successfully optimized and newly developed. Especially in the areas "volt drop" and "seat strength" this has led to significant improvements.
The reduction in volt drop is essentially achieved via two measures. On the one hand, the total plus pole is gold-plated. This includes the tube in the center core as well as the nut to which the (copper/silver sheet) strikes. On the other hand, the nut is flattened on one side flat. This means that the sheet no longer lies on only one point but has a surface of 5.3 x 4mm available.
The nut is held by means of a Allen screw . This makes it beqeum adjustable in height . The grub screw is located opposite the flattened side . When tightened, it pulls the flattened side, i.e. exactly where the main current flow takes place solid to the gold-plated tube. Another advantage against the Volt-Drop.
The thread of the 510 and the nut are designed as left-hand thread. This complicates the installation in the Mod. However, there is no danger of the connector being accidentally loosened when used .
The connector is available in silver and black. The black color was applied by PVD coating. It has a hardness greater than 2000HV, so nothing is scratched here. Furthermore the coating electrically conductive. Between nut and Top-Cap was intentionally mixed to the coating to allow an even better current flow.
The center core includes a silicone ring. This is not absolutely necessary and serves more for double security.
The entire center core is pressed into the 510er. Also here nothing can be solved in the long run .
