Connector

A connector, comprising:

• a terminal-equipped electrical wire that includes an electrical wire and a terminal which is attached to an end portion of the electrical wire, the terminal having a box-shaped portion configured to fit with a mating terminal in a fitting direction intersecting with an extending direction of the electrical wire;
• an inner housing that includes a terminal accommodating chamber communicating with a terminal fitting opening and an electrical wire leading-out opening and configured to accommodate the terminal-equipped electrical wire;
• an outer housing that includes an electrical wire leading-out opening configured to receive the inner housing in the extending direction of the electrical wire and a housing fitting opening configured to be fitted to a mating connector;
• a front holder configured to be attached to the housing fitting opening;
• and
• one or more pressing protrusions provided on at least one of the terminal and the front holder,
• wherein when the outer housing is fitted to the mating connector, the one or more pressing protrusions are elastically deformed by a fitting pressing force acting on the front holder to press and urge the box-shaped portion toward inside of the terminal accommodating chamber.
