Description

Adopt optical module of pull ring unblock Technical Field The invention relates to a mechanical structure of a photoelectric module in the technical field of optical communication, in particular to an optical module unlocked by a pull ring. Background With the rapid development of the Internet, cloud computing and big data, the construction of IT infrastructure data centers is further accelerated, and the 5G network starts to be at the developed city test point, and the 25G SFP28 optical module is also applied to the construction of 5G signal base stations. The 25G sfp28 optical module is widely used in 25G data centers in addition to 5G networks, and has an optimal input/output (I/O) performance and fiber capacity 2.5 times that of 10G ethernet, and a higher port density, and can save operating costs by reducing the number of ToR switches and cables. The SFP-25G-SR optical module is mainly used for 25G data centers and 5G forwarding CPRI/eCPRI networks. The SFP-25G-SR optical module adopts a hot pluggable SFP28 package, has the working wavelength of 850nm and is a full-duplex transceiver integrated module. Its maximum speed is up to 25.78Gbps, and its transmission distance can be up to 70m (OM 3) or 100m (OM 4) by means of multimode optical fibre. SFP-25G-SR optical modules are favored by data centers because of the ability to provide cost-effective 25G network solutions. In equipment with denser ports, the space available for the locking and unloading devices of the modules is narrower, and the unlocking operation is required to be simpler and more convenient. Meanwhile, the color code for distinguishing the module types is required to be more striking, more module information is required to be embodied on the pull ring, and a user can conveniently and quickly identify among a plurality of modules. At present, the locking and unloading mechanisms of SFP+ and SFP28 series modules mainly have two forms: The length of the first module pull ring does not exceed the module body, the movement track is a circle, namely the pull ring drives other unlocking parts to work through rotation, and unlocking of the optical module is achieved. The length of the second type module pull ring exceeds the length of the module body, the movement track is a straight line, namely the pull ring drives other unlocking parts to work through the straight line movement, and the unlocking of the optical module is realized. The first unlocking mode has higher requirement on the assembly space of surrounding parts in the rotation process of the pull ring, and in intensive equipment, interference with other modules or panels possibly occurs in the unlocking process of the pull ring, so that the pull ring cannot rotate in place and cannot be unlocked. The color code of such a module is typically made on the handle of the pull ring, and when the module is installed in the device, the module color code cannot be identified without rotating the pull ring to the light port position. The second unlocking mode is as the locking and unloading device of the module in Chinese patent CN201711326704.8, when the module needs to be unlocked, the long pull ring is pulled, the pull ring is arranged on the top surface of the module, the unlocking device is arranged on the bottom surface of the module, and the pull ring is pulled by applying oblique downward force, so that a larger bending moment can be generated, the friction force of the sliding block of the unlocking mechanism is very large, the sliding block is easy to lock, and the unlocking cannot be realized. In view of the above, how to overcome the defects existing in the prior art and solve the above technical problems is a difficult problem to be solved in the technical field. Disclosure of Invention Aiming at the defects or improvement demands of the prior art, the invention provides a novel optical module which is higher in reliability and wider in application range and adopts a pull ring for unlocking, so that the novel optical module has the following functions of being applicable to a photoelectric module which limits the maximum height of the pull ring after rotating, being applicable to communication equipment with a high-density port, being more visual in module color code and convenient to identify, being capable of realizing module band optical fiber plugging, reducing optical fiber end face pollution, being convenient to maintain and use, being smoother in module unlocking, not being blocked, being capable of automatically recovering the pull ring by releasing external force only by stirring the pull ring in the vertical direction, and being convenient and simple. The embodiment of the invention adopts the following technical scheme: The invention provides an optical module unlocked by a pull ring, which comprises the pull ring, a base, a clamping cover, a braking piece, elastic pieces and springs, wherein the springs are arranged in the base, one elastic piece is respectively arran
