Abstract: A plug connector assembly includes an insulated housing, and a flexible flat cable assembly. The flexible flat cable assembly includes a first flat cable, a second flat cable, and a reinforced board. The reinforced board is sandwiched between the first flat cable the second flat cable. An inner shielding layer is disposed between conductors of the first flat cable and the reinforced board, and between conductors of the second flat cable and the reinforced board, respectively. A positioning plate protrudes outward from each of two sides of the reinforced board. The insulated housing has a displacement-preventing mechanism formed on an inner side thereof for blocking the positioning plate, so as to limit the displacement of the reinforced board along the inserting direction.

Abstract: A long straight high-frequency transmission cable includes a plurality of transmission wires, at least one ground wire, first and second insulating laminates, and first and second shielding layers. The transmission wires and the ground wire are parallel to each other. The first insulating laminate and the second insulating laminate are laminated with each other to cover the transmission wires and the ground wire. The first shielding layer and the second shielding layer are respectively laminated on the first insulating laminate and the second insulating laminate. The first insulating laminate has a plurality of first conductive plugs separately arranged along a length direction of the ground wire, and each two adjacent ones of the first conductive plugs have a spacing therebetween that is at least greater than 50 mm.

Abstract: A flexible flat cable for transmitting high-frequency signals includes an inner flat cable and a pair of shielding composite layers, which are divided into a main section, two connecting sections, and two sealing sections. The inner flat cable is disposed in the main section, and includes a plurality of conductors, an insulated glue layer, a pair of insulated partition layers and a pair of metallic shielding layers. The pair of insulated partition layers are disposed at two sides of the conductors and are affixed oppositely. The pair of metallic shielding layers are disposed at outer sides of the pair of insulated partition layers. Each shielding composite layer has a width larger than a width of the inner flat cable, and includes an outer shielding layer and a conductive glue layer having one part affixed to the inner flat cable and another part affixed to each other.
