Abstract

Disclosed is a loading and unloading device for a long handle module, comprising a housing (100), a pull ring (200), tension springs (310, 320), a brake disc (400) and a cover plate (500). The housing (100) comprises a first cavity (116), a second cavity (102) and a U-shaped beam (115), the U-shaped beam (115) separating the first cavity (116) from the second cavity (102). The brake disc (400) comprises a base body (412), a first U-shaped groove (409), a second U-shaped groove (410), a bend structure (403) and a third inclined surface (401). The first U-shaped groove (409), the second U-shaped groove (410) and the bend structure (403) are provided on the base body (412), and the third inclined surface (401) is provided on the bending structure (403). The pull ring (200) comprises a handle (210), a pressing rod (201) and a pressing head (202), and the pressing head (202) is arranged on the pressing rod (201). The cover plate (500) includes a pressing tongue (506). The brake disc (400) in the device tilts downwards to pry the tongue (701) of a shielding cage (700) from a lock catch (101) of the housing (100) to unload the module, thereby solving the following problems: the direct-pulling type loading and unloading mechanism for modules in the prior art has high requirements on the wall thickness of the housing (100), a relief structure designed for the housing (100) influences the EMI performance, and the structure of the loading and unloading mechanism has poor reliability, narrow application range, and installation complicity.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a device for installing and unloading a long handle module. Background technique [0002] The form of the pull ring is not clearly defined in the international multiple protocols of SFP and SFP+, but the international multiple protocol of SFP-DD has clearly shown the pull ring with long handle, which shows that the pull ring with long handle is becoming the mainstream application in small package optoelectronic modules. Compared with the commonly used rotating short pull ring, the application range of the long handle pull ring is wider. The rotating short pull ring is generally used on modules with plug-in optical ports, and cannot be applied to AOC optical cable modules because the pull ring rotates During the process, it will be blocked by the optical cable, and the unloading of the module cannot be completed; the long-handle pull ring can not only be applied to m...
