Cable assembly and method for manufacturing cable assembly

A cable assembly arranged between a first connector which is arranged at a position near a control device on a substrate and a second connector which is arranged at a position away from the control device on the substrate, comprising:

• a cable row in which a plurality of cables each transmitting a differential signal are arranged side by side;
• a paddle card substrate provided with signal electrodes to which internal conductors of the plurality of cables are electrically connected and ground electrodes to which external conductors of the plurality of cables are electrically connected;
• a plastic member arranged on the paddle card substrate and comprising an outer frame portion and a plurality of inner frame portions arranged side by side with a slight gap on an inner edge of the outer frame portion;
• ground covers arranged to cover part or all of the plurality of inner frame portions;
• and potting materials arranged within the inner frame portions so as to cover at least exposed portions of the internal conductors.

A method of manufacturing a cable assembly, comprising:

• soldering a tip end of an exposed portion of an internal conductor onto a paddle card substrate;
• attaching a plastic member to the paddle card substrate, the plastic member comprising an outer frame portion and a plurality of inner frame portions arranged side by side with a slight gap on an inner edge of the outer frame portion;
• arranging a ground cover with a press-fit so as to cover part or all of the plurality of inner frame portions, and inserting and attaching the ground cover into a hole of the paddle card substrate;
• and
• injecting a potting material into the inner frame portion so as to cover an exposed portion of the internal conductor and then hardening the potting material.
