Abstract

A cable connector includes a connection end portion of a flexible board, in which a rectangular reinforcing plate molded of a conductive resin material is fixed to part of an upper surface of a ground plate. The connection end portion of the flexible board is electrically connected to a printed circuit board through the cable connector.

First claim

What is claimed is:

1 . A cable connection structure comprising:
a connection end portion of a flexible cable, the flexible cable having
a group of contact pads formed at least at one ends of a plurality of signal lines configured to transmit a signal and one ends of a plurality of ground lines to be grounded,
a ground plate electrically connected to the plurality of ground lines with respect to the contact pads, and
a reinforcing plate provided on a surface of the ground plate with respect to the contact pads, the connection end portion which the ground plate and the reinforcing plate are oppositely joined to the group of contact pads; and
a plurality of contact terminals each having a contact portion to come into contact with a corresponding one of the contact pads, the contact terminals being configured to electrically connect the connection end portion of the cable to a wiring board.

2 . The cable connection structure according to claim 1 , wherein the ground plate has a plurality of extension portions formed at a given interval along a direction of arrangement of the contact terminals.

3 . The cable connection structure according to claim 2 , wherein a ground plate piece to be electrically connected to the corresponding ground line is further formed between the extension portions adjacent to each other.

4 . The cable connection structure according to claim 1 , wherein a plurality of ground plate pieces to be electrically connected to the ground lines are further formed away from the ground plate and disposed at a given interval along a direction of arrangement of the contact terminals.

5 . A cable connector comprising:
the cable connection structure according to claim 1 ; a cable end portion accommodating portion configured to detachably accommodate the connection end portion of the cable; and a cable holding means provided to the cable end portion accommodating portion, and configured to press the connection end portion of the cable against the contact portions of the contact terminals to thus detachably hold the connection end portion on the cable end portion accommodating portion.

6 . The cable connector according to claim 5 , further comprising:
a conductive connection member provided to the cable end portion accommodating portion and configured to come into contact with fixed portions of the plurality of contact terminals electrically connected to ground line conductive layers of the cable to be connected.

7 . A cable connector comprising:
the cable connection structure according to claim 2 ; a cable end portion accommodating portion configured to detachably accommodate the connection end portion of the cable; and a cable holding means provided to the cable end portion accommodating portion, and configured to press the connection end portion of the cable against the contact portions of the contact terminals to thus detachably hold the connection end portion on the cable end portion accommodating portion.

8 . A cable connector comprising:
the cable connection structure according to claim 3 ; a cable end portion accommodating portion configured to detachably accommodate the connection end portion of the cable; and a cable holding means provided to the cable end portion accommodating portion, and configured to press the connection end portion of the cable against the contact portions of the contact terminals to thus detachably hold the connection end portion on the cable end portion accommodating portion.

9 . A cable connector comprising:
the cable connection structure according to claim 4 ; a cable end portion accommodating portion configured to detachably accommodate the connection end portion of the cable; and a cable holding means provided to the cable end portion accommodating portion, and configured to press the connection end portion of the cable against the contact portions of the contact terminals to thus detachably hold the connection end portion on the cable end portion accommodating portion.

10 . The cable connector according to claim 7 , further comprising:
a conductive connection member provided to the cable end portion accommodating portion and configured to come into contact with fixed portions of the plurality of contact terminals electrically connected to ground line conductive layers of the cable to be connected.

11 . The cable connection structure according to claim 1 , wherein the reinforcing plate is made of a conductive resin material.
