MICRO COAX CONNECTOR SYSTEM FOR MOBILE APPLICATIONS

A series of 0.40 mm pitch Micro Coax connectors from Molex Inc. are said to offer increased space savings and improved signal integrity for mobile device applications. Initially designed to run signaling through the hinge area of new swivel-type cell phones with rotating LCDs, the Micro Coax connector system is now finding use in applications such as notebook PCs that require flexible circuit routing, shielding, higher speeds and additional space savings. The connector system features an Insulation Displacement Technology (IDT) method used to terminate the centre conductor of 42 AWG coaxial cable.

The system offers a patented "double-clamp" wire grounding method for the outer conductor and cable jacket. Unlike traditional hand soldering methods that lay a solid ground bar across all wires, this method places a grounding/retention feature between each tiny coaxial wire. A second retention feature clamps into the cable insulation for firm mechanical wire retention. This method is also said to offer several key benefits over solder-bar types, including avoidance of hardened wires and wire pull out; up to 30 percent diameter space savings; consistent grounding between circuits and the shell; increased signal skew prevention; and up to 60% fewer transmission (dB) loss at frequencies between 1 to 3 MHz.
