Abstract

A cable connection structural body is used for connecting a multi-core cable having a plurality of signal lines to a substrate, and the cable connection structural body includes a substrate fixation portion that is fixed to the substrate, and a cable holding portion that forms a space passing the plurality of signal lines therethrough between the cable holding portion and a surface of the substrate when the substrate fixation portion is fixed to the substrate.

First claim

What is claimed is:

1. A cable connection structural body that is used for connecting a multi-core cable having a plurality of signal lines to a substrate, the cable connection structural body comprising:
a substrate fixation portion that is fixed to the substrate;
a hollow bundling portion that surrounds the plurality of signal lines exposed from a sheath of the multi-core cable and passed therethrough to bundle the plurality of signal lines; and
a signal lines holding portion that forms a space passing only the plurality of signal lines passed through the hollow bundling portion between the signal lines holding portion and a surface of the substrate when the substrate fixation portion is fixed to the substrate;
wherein each of the plurality of signal lines has a central conductor and an insulator that covers an outer periphery of the central conductor,
wherein the hollow bundling portion bundles the plurality of signal lines, each of which is covered by the insulator,
wherein the signal lines holding portion sandwiches and holds the plurality of signal lines, which are passed through the space and each of which is covered by the insulator, between the signal lines holding portion and the surface of the substrate to position the plurality of signal lines with respect to the substrate.

2. The cable connection structural body according to claim 1 ,
wherein the central conductor of each of the plurality of signal lines is connected to one of a plurality of signal electrodes disposed on the substrate.

3. The cable connection structural body according to claim 1 ,
wherein the cable connection structural body is made of a conductive material.

4. The cable connection structural body according to claim 3 ,
wherein the cable connection structural body is connected to a ground electrode disposed on the substrate.

5. The cable connection structural body according to claim 4 , further comprising:
a ground line connection portion which is disposed adjacently to the signal lines holding portion and to which a ground line of the multi-core cable is connected.

6. The cable connection structural body according to claim 5 ,
wherein the ground line connection portion is disposed on each of opposite sides of the signal lines holding portion.

7. The cable connection structural body according to claim 5 ,
wherein the ground line connection portion has a concave shape opening in a direction away from the surface of the substrate when the substrate fixation portion is fixed to the substrate.

8. The cable connection structural body according to claim 3 ,
wherein the signal lines holding portion has at least one protruding portion that separates adjacent two of the plurality of signal lines in order to perform positioning of the plurality of signal lines passed through the space.

9. The cable connection structural body according to claim 8 ,
wherein the protruding portion electromagnetically shields the adjacent two of the plurality of signal lines from each other.

10. The cable connection structural body according to claim 1 ,
wherein the cable connection structural body is formed of a single metal plate.

11. A cable connector comprising the cable connection structural body according to claim 1 .

12. The cable connection structural body according to claim 1 ,
wherein the substrate fixation portion projects toward the substrate and is fitted in a recess of the substrate to be fixed to the substrate.
