Connector

A connector, comprising:

• a connector housing (10, 50);
• a lock arm (13, 51) extending rearward along an outer surface of a housing body (11) of the connector housing (10, 50), the lock arm (13, 51) being resiliently displaceable in directions toward and away from the outer surface of the housing body (11);
• and
• a detector (23, 65) mounted along the outer surface of the housing body (11), the detector (23, 65) being displaceable between an initial position and a detection position forward of the initial position,
• wherein:
• a lock projection (18, 56) hookable to a lock receiving portion of a mating housing is formed on an outer surface of the lock arm (13, 51),
• a first receiving surface (21, 59) facing rearward and two second receiving surfaces (22, 64) facing rearward are formed at positions of the lock arm (13, 51) closer to the housing body (11) than the lock projection (18, 56),
• the second receiving surfaces (22, 64) are disposed at two positions sandwiching the first receiving surface (21, 59) from both sides in a width direction intersecting a resilient displacing direction of the lock arm (13, 51) in a back view,
• the detector (23, 65) is formed with a resilient arm (26, 66) cantilevered forward and displaceable in the directions toward and away from the outer surface of the housing body (11),
• the resilient arm (26, 66) includes a first butting portion (28) for restricting a movement of the detector (23, 65) at the initial position to the detection position by butting against the first receiving surface (21, 59),
• the resilient arm (26, 66) includes a separation restricting portion (30) projecting farther forward than the first butting portion (28) from a position closer to the housing body (11) than the first butting portion (28),
• the separation restricting portion (30) is capable of contacting the lock arm (13, 51) from the side of the housing body (11),
• the resilient arm (26, 66) includes two second butting portions (31, 67) projecting from both widthwise outer side surfaces of the resilient arm (26, 66), and
• the second butting portions (31, 67) restrict the movement of the detector (23, 65) at the initial position to the detection position by butting against the second receiving surfaces (22, 64).
