Further, said pin connector is USB 3.0 category-A pin connectors.

Further, said printed circuit board (PCB) also is provided with between first contact and second contact and uses the recess that springs into for the contact site end.Further, said recess is identical with second number of connections and on fore-and-aft direction, align one by one.

Further, also has a pair of circular hole between said second contact and the 3rd contact.

Further, said inner casing buries with the printed circuit board (PCB) edge and is molded over, and shell buries with printed circuit board (PCB), cable and inner casing edge and is molded over.

Further, said first contact, second contact and the 3rd contact are lined up three rows that are parallel to each other and the upper surface that all is positioned at printed circuit board (PCB).

Further, the length of said second contact is less than first contact and the 3rd contact.

Compared to prior art; Adopted the traditional insulating body (housing) of printed circuit board (PCB) (PCB) replacement in the utility model; Printed circuit board (PCB) is provided with some in order to electrically connect the contact of cable and flexible terminal, has simplified overall structure, therefore; Make assembling efficiency in the time of can promoting volume production greatly, and then reduce cost; Also can improve simultaneously the high frequency performance of signal transmission.
