Connector

A connector, comprising:

• a housing having a front end connectable to a mating housing and a rear end opposite the front end;
• and
• a slider mounted movably to an advanced position and a retracted position behind the advanced position with respect to the housing, held at the advanced position while the housing is being connected to the mating housing and permitted to move to the retracted position in a state where the housing is properly connected to the mating housing,
• wherein:
• the housing includes a housing main body, a leg projecting up from the housing main body and a lock arm having a front part projecting forward of the leg and a rear part projecting rearward of the leg, the rear part facing the housing main body via a deflection space;
• the rear part of the lock arm is deflected and deformed into the deflection space in the process of connecting the housing to the mating housing and the lock arm is displaced in a return direction to hold the mating housing in a connected state when the housing is properly connected to the mating housing;
• the slider includes a deflection regulating portion disposed in the deflection space and facing a lower surface of the rear part of the lock arm when the slider is at the retracted position for regulating deflection of the lock arm into the deflection space;
• and
• the slider includes an unlocking portion having a suspended portion with upper and lower surfaces sloped obliquely down to a rear lower side and toward the deflection space, the unlocking portion covers the rear part of the lock arm from a side opposite to the deflection space, the suspended portion covers the rear part of the lock arm from behind and presses the rear part of the lock arm toward the deflection space by receiving an operation force, thereby being able to release a locked state of the lock arm, when the slider reaches the advanced position or a position near the advanced position by being pushed forward from the retracted position.
