Connector assembly with variable axial assist
A connector includes a first-housing, a second-housing, a shroud, and a stacked-gear. The first-housing defines a guide-slot. The second-housing mates with the first-housing. The second-housing includes a linear-gear-rack extending from a second-outer-surface and engages the guide-slot. The shroud is moveable from an unmated-position to a mated-position. The shroud is longitudinally slideably mounted to and surrounding at least a portion of the first-housing. The shroud also includes a curved-gear-rack having a variable-pitch-radius. The stacked-gear is moveably mounted to the first-housing. The stacked-gear has a round-gear and a cam-gear having the variable-pitch-radius in communication with the round-gear. The round-gear engages the linear-gear-rack within the guide-slot. The cam-gear engages the curved-gear-rack such that the cam-gear moves in response to a movement of the shroud from the unmated-position to the mated-position. Rotation of the round-gear engaged with the linear-gear-rack axially pulls the linear-gear-rack into the guide-slot, thereby pulling the second-housing into the first-housing.
1. A connector, comprising:
a first-housing defining a guide-slot;
a second-housing configured to mate with the first-housing, wherein the second-housing includes a linear-gear-rack extending from a second-outer-surface and configured to engage the guide-slot;
a shroud moveable from an unmated-position to a mated-position, said shroud longitudinally slideably mounted to and surrounding at least a portion of the first-housing, and including a curved-gear-rack having a variable-pitch-radius; and
a stacked-gear moveably mounted to the first-housing, said stacked-gear having a round-gear and a cam-gear having the variable-pitch-radius in communication with the round-gear, said round-gear engaging the linear-gear-rack within the guide-slot, said cam-gear engaging the curved-gear-rack such that the cam-gear moves in response to a movement of the shroud from the unmated-position to the mated-position, wherein rotation of the round-gear engaged with the linear-gear-rack axially pulls the linear-gear-rack into the guide-slot, thereby pulling the second-housing into the first-housing.
2. The connector in accordance with claim 1 , wherein the linear-gear-rack defines a guide-side and a tooth-side and the guide-slot defines a guide-wall and an aperture, and wherein the guide-side slideably engages the guide-wall and the tooth-side is disposed within the aperture.
3. The connector in accordance with claim 2 , wherein a portion of the round-gear is disposed within the aperture and engages the tooth-side of the linear-gear-rack.
4. The connector in accordance with claim 1 , wherein the cam-gear and the curved-gear-rack have a first-pitch-radius equivalent to 1.4 times a pitch-radius of the round-gear.
5. The connector in accordance with claim 4 , wherein the cam-gear and the curved-gear-rack have a second-pitch-radius equivalent to 1.49 times the pitch-radius of the round-gear.
6. The connector in accordance with claim 5 , wherein the cam-gear and the curved-gear-rack have a third-pitch-radius equivalent to 1.73 times the pitch-radius of the round-gear.
7. The connector in accordance with claim 6 , wherein the cam-gear and the curved-gear-rack have a fourth-pitch-radius equivalent to 2.01 times the pitch-radius of the round-gear.
8. The connector in accordance with claim 7 , wherein the cam-gear and the curved-gear-rack have a fifth-pitch-radius equivalent to 2.33 times the pitch-radius of the round-gear.
9. The connector in accordance with claim 8 , wherein the cam-gear and the curved-gear-rack have a sixth-pitch-radius equivalent to 2.60 times the pitch-radius of the round-gear.
10. The connector in accordance with claim 9 , wherein the cam-gear and the curved-gear-rack have a seventh-pitch-radius equivalent to 2.74 times the pitch-radius of the round-gear.
11. The connector in accordance with claim 1 , wherein the round-gear has a constant-pitch-radius and the linear-gear-rack has a consistent pitch-spacing.
12. The connector in accordance to claim 1 , wherein at least one electrical terminal is disposed within the first-housing and at least one corresponding mating electrical terminal is disposed within the second-housing.
13. The connector in accordance with claim 12 , wherein the cam-gear and the curved-gear-rack have a first-pitch-radius equivalent to 1.4 times a pitch-radius of the round-gear, and a second-pitch-radius equivalent to 1.49 times the pitch-radius of the round-gear, and a third-pitch-radius equivalent to 1.73 times the pitch-radius of the round-gear, and a fourth-pitch-radius equivalent to 2.01 times the pitch-radius of the round-gear, and a fifth-pitch-radius equivalent to 2.33 times the pitch-radius of the round-gear, and a sixth-pitch-radius equivalent to 2.60 times the pitch-radius of the round-gear, and a seventh-pitch-radius equivalent to 2.74 times the pitch-radius of the round-gear.
14. The connector in accordance with claim 13 , wherein the round-gear has a constant-pitch-radius and the linear-gear-rack has a consistent pitch-spacing.
15. A connector, comprising:
a first-housing;
a second-housing;
a shroud; and
a stacked-gear moveably mounted to the first-housing, said stacked-gear having a round-gear and a cam-gear overlying the round-gear, said round-gear engaging a first-gear-rack on the second-housing, said cam-gear engaging a second-gear-rack on the shroud, wherein the second-housing is mated with the first-housing when the shroud is moved along a mating-axis of the connector.
