Fitting connector

A fitting connector comprising:

• a first connector that includes a terminal and a housing holding the terminal;
• a second connector that includes a counterpart terminal and a counterpart housing holding the counterpart terminal, and is configured to electrically connect the terminal with the counterpart terminal when a fitting state between the housing and the counter housing along with insertion and fitting between the housing and the counter housing is in a complete fitting state;
• and
• a holding structure that includes a first latch hold portion provided on the housing and a second latch hold portion provided on the counterpart housing, is configured to cause the first latch hold portion and the second latch hold portion to be in a state capable of latching in a connector removal direction when the fitting state is in the complete fitting state, and maintains the fitting state in the complete fitting state as is, wherein
• the holding structure includes a latch hold body on which the first latch hold portion is provided, and
• the latch hold body includes
• the first latch hold portion provided on one end in a connector insertion-removal direction,
• a latch-release operation portion provided on the other end in the connector insertion-removal direction,
• a cantilever latch arm portion on which the first latch hold portion is provided at a free end and arranged between the first latch hold portion and the latch-release operation portion,
• a latch-release arm portion coupling the first latch hold portion and the latch-release operation portion,
• a first fulcrum portion provided on the latch-release arm portion and configured to exert force in a detaching direction from the second latch hold portion on the first latch hold portion as a point of action with a contact point with a first release-operation force receiving portion as a fulcrum when the latch-release operation portion as a point of effort is pushed in a state where the first latch hold portion and the second latch hold portion are able to latch, and
• a second fulcrum portion provided on the latch-release operation portion side relative to the first fulcrum portion in the latch-release arm portion and configured to contact with a second release-operation force receiving portion on the latch-release operation portion side relative to the first release-operation force receiving portion along with continuation of the push operation and exert the force in the detaching direction from the second latch hold portion on the first latch hold portion as a point of action with a contact point with the second release-operation force receiving portion as a new fulcrum.
