Description

A module installation and unloading device and installation method thereof

technical field

The invention relates to an installation and unloading device and an installation method thereof, in particular to a module installation and unloading device and an installation method thereof, and belongs to the technical field of optical communication.

Background technique

Nowadays, system manufacturers have higher and higher requirements for the high density of photoelectric modules in the equipment, leaving less and less space for module installation and unloading devices. At the same time, the market's demand for cost reduction of optical communication network equipment is becoming stronger and stronger, forcing a huge change in the structure of the photoelectric module. For example, the height of the optical fiber outlet cannot be designed according to the needs of the peripheral structure. This limitation has a greater impact on the installation and unloading device.

At present, there are mainly two ways to install and uninstall the module: the slider is pushed forward or the shielding cage lock is tilted, and the latch is retracted into the module and released from the shielding cage lock. The disadvantage of the first method is that it is more dependent on the cage, the structure of the panel itself and the assembly relationship between them, the scope of application is narrow, and the keyhole on the cage needs to be lifted when the module is installed and unloaded, which has a great impact on the service life of the cage. Influence; the second method is self-unlocking, that is, it does not depend on the structure of external devices, has a wide range of applications, and can play a very good role in protecting the device. The installation and unloading method of the module in the Chinese patent ZL200620098737.2 is the second one.
