Connection structure and electronic substrate

A connection structure having a connector, a flat cable, and an electronic substrate, wherein the connector is configured to connect to the flat cable and to mount on the electronic substrate, comprising:

• a Type 1 connector line, on the substrate, extends along a length direction of the flat cable on one side of the substrate in a width direction that is orthogonal to the length direction;
• and a Type 2 connector line, on the substrate, extends along the length direction on an opposite side of the substrate, both of the Type 1 and Type 2 connector lines being at a location where the connector is to be mounted on the substrate;
• and
• a Type 1 cable line and an adjacent Type 2 cable line, both on the substrate, extend in parallel on both ends of the substrate in the width direction and at a location where the flat cable extends when connected to the connector,
• wherein, when the connection structure is misaligned, the Type 2 connector line is covered by the connector, and the Type 1 connector line is partly exposed,
• wherein, when the connection structure is misaligned, at an edge of one side of the flat cable, the Type 1 cable line is partly covered by the flat cable, and the Type 2 cable line is exposed at a position adjacent to an outer side of the Type 1 cable line,
• wherein, when the connection structure is misaligned, at an edge of another side of the flat cable, the Type 1 cable line is partly covered by the flat cable, and the Type 2 cable line is at a position adjacent to an inner side of the Type 1 cable line,
• the Type 1 connector line and the Type 1 cable line are lines of the same type, and
• the Type 2 connector line and the Type 2 cable line are lines of the same type but are lines of a different type from the Type 1 connector line and the Type 1 cable line.

An electronic substrate for mounting by a connector that can connect to and fix a flat cable, comprising:

• a Type 1 connector line, on the substrate, extends along a length direction of the flat cable on one side of the substrate in a width direction that is orthogonal to the length direction;
• and a Type 2 connector line, on the substrate, extends along the length direction on an opposite side of the substrate, both of the Type 1 and Type 2 connectors being at a location where the connector is to be mounted on the substrate;
• and
• a Type 1 cable line and a Type 2 cable line extend in parallel on both ends of the substrate in the width direction and at a location where the flat cable extends when connected to the connector,
• wherein, when the connector is mounted on the substrate at a normal position, the Type 1 connector line and the Type 2 connector line are covered by the connector, and outer edges of the Type 1 and Type 2 connector lines match the connector,
• wherein, when the flat cable is connected to the connector at the normal position, at an edge of one side of the flat cable, a Type 1 cable line, on the substrate, is on an inner side and a Type 2 cable line, on the substrate, is on an outer side, with the edge of the one side being a border between the Type 1 and Type 2 cable lines on the one side,
• wherein, when the flat cable is connected to the connector at the normal position, at an edge of another side of the flat cable, a Type 1 cable line, on the substrate is on an outer side and a Type 2 cable line, on the substrate is on an inner side, with the edge of the another side being a border between the Type 1 and Type 2 cable lines on the another side,
• the Type 1 connector line and the Type 1 cable line are lines of the same type, and
• the Type 2 connector line and the Type 2 cable line are lines of the same type but are lines of a different type from the Type 1 connector line and the Type 1 cable line.
