Connector

A connector comprising:

• a housing;
• a plurality of terminals installed in the housing;
• and
• an aligning plate configured to be installed in the housing and having a plurality of positioning holes into which the terminals are inserted,
• wherein the connector is configured to be mounted on a circuit board so that the terminals inserted into the positioning holes are inserted into the through holes of the circuit board;
• wherein the aligning plate has a first face and a second face on the opposite side of the first face, the second face being opposed to the circuit board during mounting onto the circuit board;
• wherein the aligning plate has a stepped shape including a plurality of faces being different in position in the mounting direction toward the circuit board on the first face;
• wherein the aligning plate has a relief section provided on the second face to avoid interference with a mounting component on the circuit board during mounting onto the circuit board;
• and
• wherein during mounting onto the circuit board, a portion of the second face through which a subset of the positioning holes pass is closer to a surface of the circuit board than the relief section.
