Cable connection structure, cable assembly, method for manufacturing cable assembly, and method for manufacturing cable connection structure
A cable connection structure includes a cable assembly that fixes a plurality of cables, and a mounting member connected to the cable assembly. The plurality of cables includes: core wires having core wire exposed portions where the core wires are exposed at distal ends of the plurality of cables; and jackets, each of which is formed of an insulator and covers each of the core wires. The mounting member includes a plurality of external connection electrodes to which the core wires are to be connected. The cable assembly includes a first cable fixing portion that is formed of an insoluble resin insoluble in organic solvents or alkali and that fixes the core wire exposed portions. The core wires are exposed on an end face of the first cable fixing portion and are connected to the plurality of external connection electrodes using a conductive material.
1. A cable connection structure comprising:
a cable assembly that fixes a plurality of cables, the plurality of cables extending in an axial direction; and
a mounting member connected to the cable assembly;
wherein the plurality of cables comprises:
core wires, each of which having a core wire exposed portion, each core wire exposed portion having:
a specified length of an outer peripheral surface of the core wire exposed in the axial direction; and
an end face of the core wire exposed; and
jackets, each of which is formed of an insulator, the jackets covering each of the core wires except for at least the core wire exposed portions;
wherein the mounting member comprises a plurality of external connection electrodes to which the core wires are to be connected;
the cable assembly further comprises a first cable fixing portion that is formed of an insoluble resin insoluble in organic solvents or alkali and that fixes and covers the entire outer peripheral surfaces of the core wire exposed portions except for the end faces of the core wires;
the core wires are exposed on an end face of the first cable fixing portion and are connected to the plurality of external connection electrodes using a conductive material;
the end face of each of the core wires being mounted to a respective one of the plurality of external connection electrodes parallel to a mounting surface of the mounting member, and
the cable connection structure further comprises a reinforcing resin provided around the conductive material and around side surfaces of the first cable fixing portion.
2. The cable connection structure according to claim 1 , wherein the reinforcing resin and the first cable fixing portion have a substantially identical coefficient of thermal expansion.
