Anti-backout latch for interconnect system

An interconnect system comprising:

• a transceiver that includes a substrate, an optical engine mounted on the substrate, and a transceiver housing that is mounted on the substrate and at least partially surrounds the optical engine;
• and
• an anti-backout latch that is pivotally attached to the transceiver housing so as to be pivotable with respect to the transceiver housing about a pivot axis, wherein the anti-backout latch extends from the pivot axis to an engagement member that is spaced from a forward-most end of the transceiver housing in a forward direction so as to abut a host module that includes a first electrical connector to which the transceiver is configured to be mated in the forward direction,
• wherein the anti-backout latch is pivotable about the pivot axis between an engaged position and a disengaged position, in the engaged position an abutment between the engagement member and the host module prevents the transceiver from being unmated from the first electrical connector in a rearward direction that is opposite the forward direction, and in the disengaged position the abutment is removed such that the transceiver is movable with respect to the first electrical connector in the rearward direction a sufficient distance so as to unmate the transceiver from the first electrical connector.

An interconnect system comprising:

• an interconnect module configured to mate with first and second electrical connectors of a host module, the first electrical connector spaced from the second electrical connector in a forward direction, and the first electrical connector configured to operate at higher data transfer speeds than the second electrical connector, the interconnect module including a module substrate, an optical engine supported by the module substrate, and a module housing mounted to the module substrate and at least partially surrounding the optical engine;
• and
• an anti-backout latch that defines at least one pivot member configured to be pivotally attached to the module housing such that the anti-backout latch is pivotable relative to the module housing about a pivot axis between the disengaged position and the engaged position, wherein the pivot axis is configured to be spaced from the second electrical connector in the forward direction when the transceiver module is mated with the first and second electrical connectors, and the anti-backout latch extends from the pivot member in the forward direction to a finger,
• whereby when the anti-backout latch is in the engaged position, 1) a first mechanical interference between the anti-backout latch and the module housing limits movement of the interconnect module in the rearward direction with respect to the anti-backout latch in a rearward direction, 2) a second mechanical interference between the finger and the host module limits movement of the latch in the rearward direction with respect to the first and second electrical connectors, and 3) the limited movements in the rearward direction prevent the interconnect module from moving in the rearward direction with respect to the first and second electrical connectors a distance that would be sufficient to unmate the interconnect module from the first and second electrical connectors, and
• whereby when the anti-backout latch is in the disengaged position, the second mechanical interference is removed, such that the interconnect module is movable in the rearward direction with respect to the first and second electrical connectors a sufficient distance so as to unmate the interconnect module from at least one of the first and second electrical connectors.

An interconnect system comprising:

• an interconnect module configured to mate with first and second electrical connectors of a host module that are mounted onto a host substrate, the first electrical connector spaced from the second electrical connector in a forward direction, and the first electrical connector configured to operate at higher data transfer speeds than the second electrical connector, the interconnect module including a module substrate, an optical engine supported by the module substrate, a module housing that at least partially surrounds the module housing;
• and
• an anti-backout latch configured to be placed in mechanical communication with the interconnect module so as to define a first mechanical interference between the anti-backout latch and the interconnect module that limits rearward movement of the interconnect module with respect to the anti-backout latch in a rearward direction that is opposite the forward direction, the anti-backout latch including at least one finger that is configured to abut a forward facing outer support surface of a securement member that supports the second electrical connector and is mounted to the host substrate,
• wherein the anti-backout latch is configured to be movable between an engaged position and a disengaged position when the interconnect module is mated with the first and second electrical connectors,
• whereby when the anti-backout latch is in the engaged position, the at least one finger defines a second mechanical interference with the support surface so as to prevent the interconnect module from moving in the rearward direction with respect to the host module a distance that would be sufficient to unmate the interconnect module from at least one of the first and second electrical connectors, and
• whereby when the anti-backout latch is in the disengaged position, at least the second mechanical interference is removed, such that the interconnect module is movable in the rearward direction with respect to the at least one electrical connector a sufficient distance so as to unmate the interconnect module from the at least one electrical connector.
