Lever-type connector
View Patent ↗There is provided a lever-type connector capable of preventing the dropping off from an inner housing from an outer housing to remain at a mating connector side, when the lever-type connector is separated from the mating connector. A lever-type connector is provided with an inner housing, an outer housing that is attached to the inner housing and that prevents the separation of a second seal; sliders that are received in slider receiving slots to move slidably and that have cam grooves into which cam pins arranged at the mating connector are inserted; and a lever that is provided at the outer housing to be movable and that slides the sliders. When the lever-type connector is separated from the mating connector, the sliders pull the inner housing in a direction away from the mating connector.
1. A lever-type connector comprising:
an inner housing;
a contact located in the inner housing;
an outer housing attached to the inner housing;
a projection arranged at the inner housing;
a projection insertion groove provided on an inner surface of the slider, wherein the projection is inserted into the projection insertion groove, the projection insertion groove pulling the inner housing via the projection when the connector is separated from the mating connector;
a family sealing member received in the inner housing to prevent separation of the family sealing member from the connector;
a slider receiving slot disposed in the outer housing;
a slider having a cam groove into which a cam pin of a mating connector is inserted; the slider being slidably received in the slider receiving slot; and
a lever being rotatably disposed on the outer housing to slide the slider;
wherein a rotational operation of the lever draws the lever-type connector to be mated or unmated with the mating connector, and
wherein the slider pulls the inner housing in a direction away from the mating connector, when the lever-type connector is separated from the mating connector.
2. The lever-type connector according to claim 1 , wherein the projection insertion groove is slightly wider than the diameter of the projection.
3. The lever-type connector according to claim 1 , wherein the inner housing pushes the outer housing in a direction away from the mating connector while pulling the inner housing when the connector is separated from the mating connector.
4. The lever-type connector according to claim 1 , wherein the outer housing pushes the inner housing in a direction closer to the mating connector when the connector is mated with the mating connector.
5. The lever-type connector according to claim 1 , wherein the slider pushes the outer housing in a direction closer to the mating connector when the connector is mated with the mating connector.
6. The lever-type connector according to claim 5 , wherein the outer housing pushes the inner housing in a direction closer to the mating connector when the connector is mated with the mating connector.
7. The lever-type connector according to claim 1 , further comprising a seal receiving space in the inner housing to receive the family sealing member.
8. The lever-type connector according to claim 7 , wherein the family sealing member is substantially plate shaped and provided with multiple electrical wire insertion openings.
9. The lever-type connector according to claim 8 , further comprising contact receiving cavities in the inner housing, the electrical wire insertion openings of the family sealing member corresponding to a position of the contact receiving cavities.
10. The lever-type connector according to claim 1 , wherein the lever includes a pair of arms and a connector that connects one end of the arms.
11. The lever-type connector according to claim 10 , further comprising an extension positioned at other ends of each of the arms.
12. The lever-type connector according to claim 11 , wherein the extension extends at a right angle with respect to the arm.
13. The lever-type connector according to claim 11 , further comprising a pivot protruding from an inner surface of each extension.
14. The lever-type connector according to claim 13 , further comprising a pivot receiving portion arranged at one end in the widthwise direction of the outer housing, the pivot fitting into the pivot receiving portion.
15. The lever-type connector according to claim 11 , further comprising a projection for slider movement positioned on an outer surface of the other end of each arm.
16. The lever-type connector according to claim 15 , further comprising a slider depression at one end portion of an inner surface of the slider, the projection fitting into a slider depression of the slider.
17. A lever-type connector comprising:
an inner housing;
a contact located in the inner housing;
an outer housing attached to the inner housing;
a family sealing member received in the inner housing to prevent separation of the family sealing member from the connector;
a slider receiving slot disposed in the outer housing;
a slider having a cam groove into which a cam pin of a mating connector is inserted; the slider being slidably received in the slider receiving slot; and
a lever being rotatably disposed on the outer housing to slide the slider, wherein the lever includes a pair of arms and a connector that connects one end of the arms;
an extension positioned at other ends of each of the arms;
a pivot protruding from an inner surface of each extension;
a pivot receiving portion arranged at one end in the widthwise direction of the outer housing, the pivot fitting into the pivot receiving portion;
wherein a rotational operation of the lever draws the lever-type connector to be mated or unmated with the mating connector, and
wherein the slider pulls the inner housing in a direction away from the mating connector, when the lever-type connector is separated from the mating connector.
18. The lever-type connector according to claim 17 , wherein the extension extends at a right angle with respect to the arm.
19. The lever-type connector according to claim 17 , further comprising a projection for slider movement positioned on an outer surface of the other end of each arm.
20. The lever-type connector according to claim 19 , further comprising a slider depression at one end portion of an inner surface of the slider, the projection fitting into a slider depression of the slider.
21. The lever-type connector according to claim 17 , further comprising a seal receiving space in the inner housing to receive the family sealing member.
22. The lever-type connector according to claim 21 , wherein the family sealing member is substantially plate shaped and provided with multiple electrical wire insertion openings.
23. The lever-type connector according to claim 22 , further comprising contact receiving cavities in the inner housing, the electrical wire insertion openings of the family sealing member corresponding to a position of the contact receiving cavities.
