Abstract
Abstract The invention relates to a bail latching device for an opto-electronic transceiver, including a pivotal latching member and a bail. The bail includes ends extending at an acute angle from a plane defined by the side arms for pivoting the latching member when the bail is rotated from a rest position to a removal position. Ideally, in the rest position, the side arms of the bail extend downwardly on each side of a front end of the transceiver. In the removal position, the bail is parallel to a removal direction, whereby the bail rotates the latching member to an unlatching position and then provides a handle to grasp while removing the transceiver from a standard cage.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
191 words
A hot-pluggable optical transceiver device for mounting in a host device comprising: an optical sub-assembly for converting electrical signals into optical signals or optical signals into electrical signals; a housing supporting the optical sub-assembly hot pluggable into the host device along an insertion direction; an optical connector for receiving an optical fiber for transmitting the optical signals to the optical sub-assembly; an electrical connector for transmitting the electrical signals between the optical sub-assembly and the host device; a latch pivotally mounted on the housing between a latched and an unlatched position for holding the housing in the host device; and a bail pivotally mounted on the housing for pivoting between a rest and a removal position, in which the latch is pivoted into the unlatched position, the bail including: a grip portion extending transverse to the optical connector; first and second side arms extending perpendicularly from the grip portion and parallel to each other, defining a rotation plane; and first and second lever arms extending from the first and second side arms, respectively, out of the rotation plane for applying a force to the latch when rotated into the removal position.
Claim 2
Dependent Claim
191 words
A hot-pluggable optical transceiver device for mounting in a host device comprising: an optical sub-assembly for converting electrical signals into optical signals or optical signals into electrical signals; a housing supporting the optical sub-assembly hot pluggable into the host device along an insertion direction; an optical connector for receiving an optical fiber for transmitting the optical signals to the optical sub-assembly; an electrical connector for transmitting the electrical signals between the optical sub-assembly and the host device; a latch pivotally mounted on the housing between a latched and an unlatched position for holding the housing in the host device; and a bail pivotally mounted on the housing for pivoting between a rest and a removal position, in which the latch is pivoted into the unlatched position, the bail including: a grip portion extending transverse to the optical connector; first and second side arms extending perpendicularly from the grip portion and parallel to each other, defining a rotation plane; and first and second lever arms extending from the first and second side arms, respectively, out of the rotation plane for applying a force to the latch when rotated into the removal position.
Claim 3
Dependent Claim
25 words
The device according to claim 1 , wherein the first and second lever arms extend substantially perpendicular to the first and second side arms, respectively.
Claim 4
Dependent Claim
29 words
The device according to claim 2 , wherein the first and second lever arms extend diagonally out of the rotation plane at an angle of substantially 12° to 18°.
Claim 5
Dependent Claim
16 words
The device according to claim 3 , wherein the bail is a single piece of wire.
Claim 6
Dependent Claim
27 words
The device according to claim 2 , wherein the first and second lever arms extend diagonally out of the rotation plane at an angle of substantially 15°.
Claim 7
Dependent Claim
26 words
The device according to claim 1 , wherein in the removal position, the first and second side arms are disposed substantially parallel to the insertion direction.
Claim 8
Dependent Claim
32 words
The device according to claim 6 , further comprising a shoulder on said housing to abut said first and second lever arms for preventing the bail from rotating past the removal position.
Claim 9
Dependent Claim
31 words
The device according to claim 1 , wherein, in the rest position, the first and second side arms are disposed adjacent to the optical connector substantially perpendicular to the insertion direction.
Claim 10
Dependent Claim
33 words
The device according to claim 1 , wherein a length of the gripping portion is less than a width of the housing to ensure the bail does not interfere with other adjacent transceivers.
Claim 11
Dependent Claim
30 words
The device according to claim 1 , wherein the first and second side arms include a bend towards the front of the housing to facilitate access to the grip portion.
Claim 12
Dependent Claim
29 words
The device according to claim 1 , wherein the first and second lever arms extend diagonally out of the rotation plane at an angle of substantially 12° to 18°.
Claim 13
Dependent Claim
27 words
The device according to claim 1 , wherein the first and second lever arms extend diagonally out of the rotation plane at an angle of substantially 15°.
Claim 14
Dependent Claim
16 words
The device according to claim 1 , wherein the bail is a single piece of wire.
Claim 15
Dependent Claim
42 words
The device according to claim 1 , wherein the latch includes a latch hook on one end thereof for engaging a cage on the host device, and a block on the other end thereof for engaging the first and second lever arms.
