Latching mechanism for a carrier tray
View Patent ↗A latching mechanism in a carrier tray is provided herein. The latching mechanism may include a sliding rack gear with gear teeth and a lever arm that includes a gear mechanism that engages with the gear teeth of the sliding rack gear. The latching mechanism may include a number of gears, where the gears may operatively couple the sliding rack gear with a first latching member and a second latching member. The first latching member may be disposed along a first end of a sliding rack. The second latching member may be disposed along a second end of the sliding rack. Movement of the lever arm to a closed position may actuate the sliding rack, thereby, simultaneously rotating the first and the second latching members. The simultaneous rotation of the latching members may supply a balanced force of pressure upon the carrier tray to alleviate the binding of connectors.
1. A carrier tray comprising a latching mechanism, wherein the latching mechanism comprises:
a sliding rack gear, wherein the sliding rack gear comprises a plurality of gear teeth;
a lever arm disposed on a front edge of the carrier tray, wherein the lever arm includes a gear mechanism disposed within an interior of the carrier tray and engaged with the plurality of gear teeth on the sliding rack gear;
a plurality of gears, wherein the plurality of gears operatively couples the sliding rack gear with a first latching member and a second latching member;
the first latching member disposed along a first side of the carrier tray and at a first end of the sliding rack gear;
the second latching member disposed along a second side of the carrier tray, opposite the first latching member, and at a second end of the sliding rack gear; and
wherein a movement of the lever arm to a closed position moves the sliding rack gear, and the movement of the sliding rack gear substantially simultaneously rotates the first latching member and the second latching member.
2. The carrier tray of claim 1 , comprising mounting points to mount a circuit board to the carrier tray, wherein the circuit board comprises connectors located on an edge of the carrier tray opposite to the lever arm.
3. The carrier tray of claim 1 , wherein the first latching member and the second latching member provide a substantially even force at each side of the carrier tray as the lever arm is moved to the closed position.
4. The carrier tray of claim 2 , wherein the first latching member and the second latching member push the connectors into mating connectors of a frame as the lever arm is moved to the closed position.
5. The carrier tray of claim 1 , comprising a catch to secure the lever arm in a locked position or to release the lever arm in an open position.
6. The carrier tray of claim 5 , comprising a resilient member to hold the catch when the lever arm is in the closed position.
7. The carrier tray of claim 1 , wherein the sliding rack gear includes a low profile of a height of less than about 1 mm in material thickness.
8. A computing device, comprising:
a slot comprising:
an opening to accept insertion of a carrier tray;
pins disposed at each side of the opening; and
a first electrical connector disposed at a back of the opening;
the carrier tray, comprising:
a latching mechanism, comprising:
a sliding rack gear, wherein the sliding rack gear comprises a plurality of gear teeth;
a lever arm disposed on a front edge of the carrier tray, wherein the lever arm includes a gear mechanism disposed within an interior of the carrier tray and engaged with the plurality of gear teeth;
a plurality of gears, wherein the plurality of gears operatively couples the sliding rack gear with a first latching member and a second latching member;
the first latching member disposed along a first side of the carrier tray and at a first end of the sliding rack gear;
the second latching member disposed along a second side of the carrier tray, opposite the first latching member, and at a second end of the sliding rack gear; and
wherein a movement of the lever arm to a closed position moves the sliding rack gear, and the movement of the sliding rack gear substantially simultaneously rotates the first latching member and the second latching member, wherein each engages with the pins at each side of the opening; and
a circuit board mounted to the carrier tray, wherein the circuit board comprises a second electrical connector disposed along a back edge of the carrier tray, opposite the lever arm, wherein pressure from the first latching member and the second latching member against the pins is sufficient to couple the second electrical connector with the first electrical connector.
9. The computing device of claim 8 , wherein a catch secures the lever arm in a closed position when the first electrical connector is coupled to the second electrical connector.
10. The computing device of claim 8 , wherein the first latching member and the second latching member provide a balanced sliding force upon the carrier tray as it is removed or inserted into the slot.
11. The computing device of claim 10 , wherein the first electrical connector and the second electrical connector are coupled under the balanced sliding force.
