Lever-operative connector
View Patent ↗A lever-operative connector which can be downsized includes a frame and a lever rotatably coupled to the frame. The frame has a circumferential wall having one opening and the other opening at both ends. The frame has a notch formed in the circumferential wall and communicating with the one opening. When the lever is rotated toward the one opening side, a part of a lever side wall is exposed from an interior of the circumferential wall so as to compensate the notch of the circumferential wall, thereby forming, together with the frame, a hood having the housing-receiving width. When the lever is rotated toward the other opening side, the part of the lever side wall is received inside the circumferential wall so as to open the notch of the circumferential wall, thereby eliminating the housing-receiving width and the hood.
1. A lever-operative connector, comprising:
a tube-shaped frame having a circumferential wall having one opening and a second opening at both ends;
a lever rotatably coupled to the frame;
one connector housing having a follower, which is engageable with a cam portion of the lever, and being capable of being received inside the frame via a housing-receiving width communicating with the one opening; and a second connector housing received inside the frame via the second opening, and being engageable with the one connector housing,
wherein the lever is rotated from the one opening side toward the second opening side so as to guide the follower along the cam portion, thereby allowing the one connector housing to be received inside the frame,
wherein the frame has a cut out portion formed in a part of the circumferential wall and communicating with the one opening,
wherein when the lever is rotated toward the one opening side, each part of a lever side wall is exposed from the interior of the circumferential wall so as to entirely fill the cut out portion of the circumferential wall, thereby forming, together with the frame, a hood having the housing-receiving width, and
wherein when the lever is rotated toward the second opening side, the part of each lever side wall is received inside the circumferential wall so as to open the cut out portion of the circumferential wall, thereby eliminating the housing-receiving width and the hood.
2. The lever-operative connector according to claim 1 , wherein an interior of the circumferential wall is provided with a rib extending in a direction connecting the one opening to the other opening and not interfering with a rotation of the lever, and wherein the one connector housing is provided with a rib groove which is engageable with the rib.
3. The lever-operative connector in accordance with claim 1 , wherein the one opening side of the circumferential wall is firstly passed through a panel so that the circumferential wall of the frame is coupled to the panel.
4. The lever-operative connector in accordance with claim 3 , wherein the frame includes a plurality of protrusions adapted to abut an end face of the panel.
5. The lever-operative connector in accordance with claim 1 , wherein each frame side wall is in an approximately trapezoidal shape of which length along a longitudinal axis of the circumferential wall is gradually greater as it is close to the other opening from the one opening.
6. A lever-operative connector, comprising:
a tube-shaped frame having a circumferential wall having one opening and a second opening at both ends, the tube-shaped frame further having first and second side walls, the first and second sidewalls defining first and second bearing holes,
a lever rotatably coupled to an interior of the first and second sidewalls of the frame, the lever including first and second sidewalls, the first and second sidewalls of the lever having first and second supportive shafts adapted to engage with the first and second bearing holes, respectively, the support shafts entering into the bearing holes from the interior of the frame;
one connector housing having a follower, which is engageable with a cam portion of the lever, and being capable of being received inside the frame via a housing-receiving width communicating with the one opening; and
a second connector housing received inside the frame via the second opening, and being engageable with the one connector housing,
wherein the lever is rotated from the one opening side toward the second opening side so as to guide the follower along the cam portion, thereby allowing the one connector housing to be received inside the frame,
wherein the frame has a cut out portion formed in a part of the circumferential wall and communicating with the one opening,
wherein when the lever is rotated toward the one opening side, a part of a lever side wall is exposed from the interior of the circumferential wall so as to entirely fill the cut out portion of the circumferential wall, thereby forming, together with the frame, a hood having the housing-receiving width, and
wherein when the lever is rotated toward the second opening side, the part of the lever side wall is received inside the circumferential wall so as to open the cut out portion of the circumferential wall, thereby eliminating the housing-receiving width and the hood.
7. The lever-operative connector in accordance with claim 6 , wherein the first and second lever side walls have respective outer side faces, the first and second outer side surfaces being substantially coplanar with first and second outer side faces of the first and second frame side walls, respectively.
