ConceptThe body of plug was lathed in one piece to avoid the conduction loss when signal through the different structure and interface.
Shell between body isolate by insulator material. Depends on the method of processing, it can choose to make the shell be a conductor. The conductor is made from high-purity tellurium copper without nickel base. By using highest quality of design techniques and material to provide customer who has "Hi-End" requirement. |

DescriptionMechanical structure：
The center pin is fixed to the POM insulator by assemble function Ring and the end sleeve is separate by POM, then assemble with center pin. There’ s a hole between the contact pin and body structure. To put the fillers into the gap of the body from the hole. Use the POM latch through to fix the body. The body and the shell locked by screwing. POM sleeve is fixed with end of shell by using screw. Note： This product is include: screw for cable 3 mm*1pcs and 4 mm*1pcs. Due to the 3.5mm plug size is small, the over soldering time will cause the insulator damage or swelling. Please process solder each channel based on recommend soldering temperature and condition. Assembly： 1. We recommend to peel off the cable jacket and per conductor wire insulation. 2.Depends on cable size to decide whether use sleeve (ID 4.5mm) [311], or without sleeve (ID6.5MM) [301].Then through into cable. 3.Contact the cable with per channel by soldering. 4.Lock the shell and body [203], 5. Please lock the cable and shell with a screw M3x4mm [321] or M3x3mm [322].
