Abstract
Abstract A twinax coaxial flat cable connector assembly ( 1 ) includes a plurality of twinax coaxial wires ( 10 ), an insulative insert ( 20 ), a plurality of terminals ( 30 ), a housing ( 40 ), a grounding bar ( 309 ), and an EMI shield ( 50 ). Each twinax coaxial cable includes a pair of coaxial conductors ( 103 ), an insulating layer ( 104 ) isolating the pair of conductors from each other, a metal braid layer ( 105 ) enclosing the insulating layer, and a cable jacket ( 106 ) enclosing the metal braid layer. The elongate insulative insert defines a plurality of channels ( 202 ), a plurality of slots ( 204 ) each with a pair of projections ( 206 ) and a groove ( 205 ), and an elongate slot ( 201 ) connecting the channels with the slots. In assembly, the channels position the jackets of the twinax coaxial cables, each groove secures a rear portion of a corresponding terminal, each coaxial conductor is secured between a corresponding pair of projections and electrically connects with a corresponding terminal, and the grounding bar is inserted into the elongate slot to electrically connect to the metal braid layer of all the twinax coaxial wires. The shield is assembled to the outside of the housing and the insert is assembled into the housing such that the shield electrically contacts the grounding bar in the insert. Thus the improved insert securely positions and holds the coaxial conductor and the shielding effect is improved.
