Latching mechanism for a module
View Patent ↗One embodiment includes a latching mechanism having a latch, a cam and a slider. The cam is configured to rotate about an axis of rotation. The cam is also configured to displace an end of the latch when the cam is rotated about the axis of rotation. The slider is operably connected to the cam and is configured to cause the cam to rotate about the axis of rotation. Some embodiments also include a retaining cover and a boot. The retaining cover secures a second end of the latch to a module in which the latching mechanism is implemented. The boot is operatively connected to the slider and can be manipulated by a user to activate the slider.
1. A module comprising:
a shell defining a cavity within which at least one transmitter and at least one receiver are disposed for transmitting and receiving data signals, the shell including two slots; and
a latching mechanism, the latching mechanism comprising:
a cam including two pins defining an axis of rotation, the two pins being received in the two slots of the shell, the cam further including a connecting portion extending between the two pins, a lifting member extending from the connecting portion, and a cam leg extending from each end of the connecting portion;
a latch having a first end and a second end with the first end positioned above the lifting member of the cam and the second end secured to the shell, the latch further including a plurality of protrusions formed in the first end, each of the plurality of protrusions having a sloped leading edge; and
a slider having two cutouts within which the cam legs of the cam are received.
2. The module of claim 1 , wherein the module is substantially compliant with the CXP form factor.
3. The module of claim 1 , wherein the second end of the latch has a cutout that engages a protrusion of the shell.
4. The module of claim 1 , wherein the shell comprises a top shell and a bottom shell, the latching mechanism further comprising a retaining cover at least partially surrounding an end of the top shell and bottom shell and securing the top shell and bottom shell together.
5. The module of claim 4 , wherein the retaining cover includes a resiliency curved section configured to exert a downward force on the second end of the latch against the shell.
6. The module of claim 4 , wherein the retaining cover is color-coded, the color-coding providing information concerning a characteristic of the module.
7. The module of claim 1 , further comprising a plurality of springs configured to bias the slider to a non-activated position.
8. The module of claim 7 , wherein the slider includes a plurality of tabs configured to be engaged by the plurality of springs.
9. The module of claim 1 , wherein the slider includes a plurality of coupling structures.
10. The module of claim 9 , wherein the latching mechanism further comprises a boot overmolded over the plurality of coupling structures of the slider such that the slider and boot are operatively connected together.
11. A module comprising:
a shell defining a cavity within which at least one transmitter and at least one receiver are disposed for transmitting and receiving data signals, the shell including two slots; and
a latching mechanism, the latching mechanism comprising:
a cam including two pins defining an axis of rotation, the two pins being received in the two slots of the shell, the cam further including a connecting portion extending between the two pins, a lifting member extending from the connecting portion, and a cam leg extending from each end of the connecting portion;
a latch having a first end and a second end with the first end positioned above the lifting member of the cam and the second end secured to the shell, the latch further including a protrusion formed in the first end configured to engage a corresponding structure of a receptacle of a host device to thereby selectively secure the module at least partially within the receptacle of the host device; and
a slider having two cutouts within which the cam legs of the cam are received.
12. The module of claim 11 , further comprising a boot operably connected to the slider.
13. The module of claim 12 , wherein the boot includes a handle.
14. The module of claim 13 , wherein:
the slider includes a plurality of coupling structures; and
the boot is overmolded over the plurality of coupling structures to operably connect the boot to the slider.
15. The module of claim 11 , wherein the latching mechanism further comprises a retaining cover configured to substantially constrain the second end of the latch opposite the first end of the latch from being displaced by rotation of the cam.
16. The module of claim 15 , wherein the cover comprises a thermally insulating material.
17. The module of claim 15 , wherein the retaining cover includes a resiliently curved section configured to bias the latch into a latched position and bias the slider to a non-activated position.
18. The module of claim 11 , wherein:
the shell includes a protrusion; and
the second end has a cutout configured to engage the protrusion of the shell.
19. The module of claim 11 , wherein the lifting member is configured to displace the first end of the latch when the cam is rotated about the axis of rotation.
20. The module of claim 11 , wherein the slider is operably connected to the cam and configured to cause the cam to rotate about the axis of rotation.
