Embodiment

[0044] This embodiment provides a self-sinking unlocked SFP+ module detachment prevention structure, which is suitable for coaxial device packaging of optical modules, such as PCBA of TOSA & ROSA. The module structure mainly consists of (a) PCB positioning and packaging structure, (b) device positioning and packaging structure, (c) unlocking and anti-off mechanism. The unlocking mechanism adopts the principle of sliding baroclinic pressure, the pull ring is rotated, the rotating shaft pushes the brake block to translate, and the baroclinic protrusion sinks to realize unlocking. The upper cover and the base limit the rotation range of the rotation projection. Control the rotation of the pull ring within the range of 0° to 90°, which meets the protocol requirements of the current mainstream SFP+ optical modules. In the locked state, the side wings of the bump design are pressed against the jumper to prevent the bump from accidentally unlocking the module and falling off. In th...

Abstract

The invention relates to a module anti-shedding structure, belongs to the optical communication device field and especially relates to a SFP+ module anti-shedding structure of self-sinking unlocking.The invention provides an unlocking anti-shedding structure of an optical communication module SFP+ and is suitable for coaxial device packaging of an optical module, such as PCBA of TOSA&ROSA. A module structure is mainly formed by a (a) PCB positioning packaging structure, a (b) device positioning packaging structure and a (c) unlocking and anti-shedding mechanism. The unlocking mechanism adoptsa slip barocline principle. A pull ring is rotated, a rotation shaft pushes a brake block to translate, and a baroclinic convex block is sunk so as to realize unlocking. An upper cover and a pedestalrestrict a rotation interval of a rotated convex block. The pull ring is controlled to rotate in a 0 to 90 degree range, which accords with a protocol requirement of a current mainstream SFP+ opticalmodule. In a locked state, a side wing designed on the convex block is pressed on a jumper wire so as to prevent unintentional unlocking of the convex block and shedding of the module. In the unlocked state, the jumper wire is pulled out, the convex block sinks freely and normal unlocking is not influenced.

Description

technical field [0001] The invention relates to a module detachment prevention structure, which belongs to the field of optical communication devices, in particular to a self-sinking unlocked SFP+ module detachment prevention structure. Background technique [0002] The rapid development of the optical communication industry has driven the replacement of optical modules. In the current increasingly fierce market competition in optical communication, the demand for communication equipment with smaller and smaller volumes, higher interface density and interface board inclusion. In order to meet the needs of optical communication equipment, optical modules are developed in highly integrated small packages. The optical module SFP+ is still the mainstay of the optical module family in the past 5 to 10 years. Especially in recent years, the long-distance 40km LR SFP+ has developed rapidly. The improvement and optimization of SFP+ optical modules has great prospects and significa...
