Patent ID: 6942516

Claim:
A connector comprising: a connector body, which has a first fitting portion to be fitted with a second fitting portion of a mating connector, wherein the first fitting portion projects in a first direction and is formed with at least one engagement depression, which is depressed in a second direction perpendicular to the first direction; a coupling member, which is movably fitted with the connector body with a predetermined gap kept between the coupling member and the first fitting portion in the second direction, wherein a movable range of the coupling member is between first and second positions in the first direction, the coupling member faces the engagement depression in the second direction when being positioned at the first position, and the coupling member does not face the engagement depression in the second direction when being positioned at the second position; and urging means for urging the coupling member to be positioned at the first position, wherein the first fitting portion has an outer peripheral surface, in which the engagement depression is formed; and the coupling member has a tubular portion, which surrounds the outer peripheral surface of the first fitting portion with the predetermined gap kept between the tubular portion and the outer peripheral surface of the first fitting portion in the second direction, the connector further comprising an outer cover, which covers and supports the coupling member to keep the predetermined gap, wherein the outer cover is movably fitted with the connector body; the outer cover has a slit, which is elongated in the first direction and has a front wall portion; the coupling member is formed with an outwardly-projecting portion, which is movably positioned within the slit of the outer cover and has a front surface; such that when the coupling member is positioned at the first position, the front surface of the outwardly-projecting portion is brought into contact with the front wall portion of the slit of the outer cover; such that when only the coupling member is provided with a backward force which moves the coupling member out along the first direction, the front surface of the outwardly-projecting portion is moved away from the front wall portion of the slit of the outer cover; and such that when the outer cover is moved out along the first direction, the front wall portion of the slit of the outer cover presses the front surface of the outwardly-projecting portion backwardly in the first direction, so that the coupling member is moved to or towards the second position, and wherein the urging means is between the connector body and the outer cover and is separated from the slit by the coupling member over the coupling member's movable range.
