Abstract

Latching mechanisms for electronic modules. In one example embodiment, a latching mechanism for an electronic module includes a latch, a latch return spring, and a release slide. The latch is configured to rotate between a latched position and an unlatched position. The latch includes a latch arm on a first end of the latch and an engagement pin on a second end of the latch. The latch return spring is configured to bias the latch in the latched position. The release slide includes a slide ramp. The slide ramp is configured to engage the latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

Claims

1. A latching mechanism for an electronic module, the latching mechanism comprising:

a latch configured to rotate between a latched position and an unlatched position, the latch comprising;

a latch arm on a first end of the latch; and

an engagement pin on a second end of the latch;

a latch return spring configured to bias the latch in the latched position; and

a release slide comprising a slide ramp configured to engage the latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

2. The latching mechanism as recited in claim 1, wherein:

the latch defines a latch slot; and

the latch return spring defines a latch tab that is configured to be at least partially positioned in the latch slot.

3. The latching mechanism as recited in claim 1, wherein:

the latch further comprises a second latch arm on the first end of the latch; and

the release slide further comprises a second slide ramp configured to engage the second latch arm as the slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

4. The latching mechanism as recited in claim 3, wherein the slide ramp and the second slide ramp comprise substantially flat tabs that are angled with respect to the portion of the slide to which the substantially flat tabs are attached.

5. The latching mechanism as recited in claim 1, wherein the engagement pin defines a ramped surface that faces away from the first end of the latch.

6. The latching mechanism as recited in claim 1, further comprising a slide spring configured to bias the release slide toward the engagement pin.

7. The latching mechanism as recited in claim 1, further comprising a handle attached to the release slide, the handle configured to be manually pulled in order to slide the release slide away from the engagement pin.

8. An electronic module comprising:

a shell defining a cross bar; and

a latching mechanism comprising;

a latch configured to rotate about the cross bar between a latched position and an unlatched position, the latch comprising;

a latch arm on a first end of the latch; and

an engagement pin on a second end of the latch; and

a release slide comprising a slide ramp configured to slide along the latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

9. The electronic module as recited in claim 8, wherein the latching mechanism further comprises a latch return spring configured to bias the latch in the latched position.

10. The electronic module as recited in claim 9, wherein:

the latch defines a first latch slot; and

the latch return spring defines a latch tab that is at least partially positioned in the latch slots.

11. The electronic module as recited in claim 10, wherein the cross bar is positioned between the latch and at least a portion of the latch tab.

12. The electronic module as recited in claim 8, wherein the latching mechanism further comprises first and second slide springs configured to bias the release slide toward the engagement pin.

13. The electronic module as recited in claim 12, wherein the shell further defines a latch recess configured to receive the second end of the latch when the latch is rotated into the unlatched position.

14. The electronic module as recited in claim 8, wherein:

the latch further comprises a second latch arm on the first end of the latch; and

the release slide further comprises a second slide ramp configured to slide along the second latch arm as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position.

15. The electronic module as recited in claim 14, wherein the shell further defines first and second latch shoulders positioned between the slide ramp and the second slide ramp.

16. An electronic module comprising:

a shell defining a cross bar; and

a latching mechanism comprising;

a latch configured to rotate about the cross bar between a latched position and an unlatched position, the latch comprising;

first and second latch arms defined on a first end of the latch; and

an engagement pin defined on a second end of the latch;

a latch return spring configured to bias against the first end of the latch to maintain the latch in the latched position;

a release slide comprising first and second slide ramps configured to engage the first and second latch arms, respectively, as the release slide is slid away from the engagement pin, which causes the latch to rotate from the latched position to the unlatched position;

first and second slide springs configured to bias the release slide toward the engagement pin; and

a handle attached to the release slide, the handle configured to be manually pulled in order to slide the release slide away from the engagement pin.

17. The electronic module as recited in claim 16, wherein the shell further defines first and second latch shoulders positioned between the first and second slide ramps.

18. The electronic module as recited in claim 16, wherein:

the shell further defines first and second shell slots; and

the latch return spring defines first and second shell tabs that are at least partially positioned in the first and second shell slots, respectively.

19. The electronic module as recited in claim 18, wherein the latch return spring comprises a leaf spring.

20. The electronic module as recited in claim 16, wherein the first and second slide springs comprise coil springs.
