A connector includes a female connector housing, that has a male terminal, and a male connector housing that has a female terminal for electrical connecting to the male terminal, and that is adapted to be fitted into the female connector. The male connector housing includes an inner housing which has the female terminal, and which is adapted to be fitted in the female connector housing so that the female terminal is connected to the male terminal, and an outer housing which is adapted to support the inner housing so that the inner housing is movable in a first direction in which the inner housing is fitted in the female connector housing and in a second direction perpendicular to the first direction. When the inner housing is fitted into the female connector housing, the inner housing is disposed so as to separate from the outer housing in the second direction with a first gap.
1. A connector, comprising:
a female connector housing, that has a male terminal; and
a male connector housing that has a female terminal for electrical connecting to the male terminal, and that is adapted to be fitted into the female connector housing,
wherein the male connector housing includes:
an inner housing which has the female terminal, and which is adapted to be fitted in the female connector housing so that the female terminal is connected to the male terminal; and
an outer housing which is adapted to support the inner housing so that the inner housing is movable with respect to the outer housing in a first direction in which the inner housing is fitted in the female connector housing and is movable in a second direction perpendicular to the first direction;
wherein when the inner housing is fitted into the female connector housing, the entire inner housing is disposed so as to be isolated from the outer housing in the second direction;
wherein a rib and a rib receiving portion are respectively formed on an outer surface of the inner housing and an inner surface of the outer housing which are opposed to each other in the second direction;
wherein when the inner housing is not fitted into the female connector housing, the rib opposes the rib receiving portion in the second direction so that the rib overlaps with the rib receiving portion in the second direction preventing the inner housing from moving relative to the outer housing in the second direction; and
wherein when the inner housing is fitted into the female connector housing, the rib is shifted away from the rib receiving portion in the first direction so as not to overlap with the rib receiving portion in the second direction, so that a gap is formed between the inner housing and the outer housing thereby allowing the inner housing to move relative to the outer housing in the second direction only when in the inner housing is fitted into the female connector housing.
2. The connector according to claim 1 , wherein a first slanting surface is formed on the outer surface of the inner housing;
wherein a second slanting surface is formed on an inner surface of the female connector housing, and is corresponded to the first slanting surface; and
wherein the first slanting surface is mated with the second slanting surface.
3. The connector according to claim 2 , further comprising an urging unit that is interposed between the inner housing and the outer housing,
wherein when the inner housing is fitted into the female connector housing, the urging unit urges the inner housing in the first direction so that the first slanting surface of the inner housing is pressed against the second slanting surface of the female connector housing.
4. The connector according to claim 1 , wherein when the inner housing is fitted into the female connector housing, a portion of the female connector housing enters a space between the outer surface of the inner housing and the inner surface of the outer housing so that the inner housing becomes fixed in the position with respect to the female connector housing, thereby forcing the inner housing and the outer housing to move from a contacting condition to a non-contacting condition.
