Abstract: An electrical connector provided in the present invention comprises a circuit board and a connecting wire member. The circuit board includes an upper circuit layer, a lower circuit layer, and a shielding layer. The connecting wire member includes a plurality of upper wires and a plurality of lower wires. The upper circuit layer has an upper concave portion made by removing circuit, and the lower circuit layer has a lower concave portion made by removing circuit. The upper wire set is disposed in the upper concave portion, and the lower wire set is disposed in the lower concave portion. Thus, the shielding between the upper wire set and the lower wire set is achieved, and the assembling and processing of wires and circuit layer is easier.

Abstract: A structure of signal cable connector, which is connected to the signal cable between the hard disk and the computer's main board, comprises at least an enclosure, a circuit board and a wire strand. Wherein a wire block is utilized to affix the signal wires and a ground block to conduct the soldered ground wires so as to minimize the solder points incurred by direct solder of conducting wires on circuit board, resulting in easier assembly and optimized yield.
