Patent ID: 7223121

Claim:
A cable connector for balanced transmission, comprising: a contact assembly body having a block body made of an electrically insulating material in which a pair including first and second signal contact members and a ground contact member are alternately arrayed; wherein a first signal wire connecting part being a part of the first signal contact member sticks out from the back face of the block body, a second signal wire connecting part being a part of the second signal contact member sticks out from the back face of the block body, and a plate part and a drain wire connecting part at the end of the plate part being parts of the ground contact member stick out from the back face of the block body; the cable connector for balanced transmission, further including a cable for balanced transmission having plural pairs of wires in which the first and second signal wires and the drain wire are disposed; wherein a tip of the first signal wire is connected to the first signal wire connecting part, a tip of the second signal wire is connected to the second signal wire connecting part, and a tip of the drain wire is connected to the drain wire connecting part; the cable connector for balanced transmission further including a spacer member being a plate-shaped member made of an electrically insulating material that has first grooves that have a shape corresponding to the first signal wire connecting part, second grooves that have a shape corresponding to the second signal wire connecting part, and slits that have a shape corresponding to the plate part of the ground contact member; wherein the spacer member is attached to the back face of the block body, the first signal wire connecting part is inserted into the first groove, the second signal wire connecting part is inserted into the second groove, and the plate part is inserted into the slit, so that the positions of the first and second signal contact members and the ground contact members in relation with the tips of the cable for balanced transmission are decided.
