Background technology
In optical communication industry, optical module is an indispensable part.Wherein, there is 40G, 100G transmission rate
Optical communication module encapsulated mostly using QSFP+, and the encapsulation mostly uses drawing type unlocking mechanism.Drawing type unlocking mechanism
Benefit be that directly can extract optical module without other unlocked steps from optical module cage, and the drawing have reset
Function, that is, unlocking mechanism automatically resets to original state after extracting, and is easy to insert optical module after optical module cage certainly next time
Dynamic locking is without other any operations.In order to realize above-mentioned function, usually using following scheme.
Existing technical scheme one：Generally use pacifies spring-loaded mode, sets metal plate bending to coordinate with spring on draw ring,
Spring has certain stroke, has certain decrement in stroke.Make draw ring and solution using elastic force caused by the decrement of spring
Latch mechanism automatically resets.It has the following disadvantages：1) because optical module structure is compact, and, spring also restricted to draw ring pulling capacity
Superfine spring, such spring poor reliability need to be selected, drawing number excessively easily fails；And such spring spring silk compares because of itself
Relatively thin, if slightly gap in the mounting groove of spring, that spring silk when stress extrudes easily is stuck in the gap, causes drawing
Failure；2) from installing, the installation of such spring is cumbersome, needs to make spring first have certain decrement just to put during installation
Enter mounting groove, and because spring size itself is minimum, it is necessary to operate this process with tweezers, therefore it is excessively cumbersome.
Existing technical scheme two：By the way of draw ring sheet metal component directly rushes reed, i.e., rushed in the metal plate part of draw ring
Go out one section of bending reed.Reed installation after also have certain decrement and produce elastic force, by the elastic force of reed cause draw ring and
Unlocking mechanism automatically resets.This programme eliminates the installation of spring compared with prior art one.Reed is directly rushed on metal plate, though
The step of so removing installation spring from, operation become easy, it also avoid the problem of hairspring is stuck in gap.But also have simultaneously such as
Lower shortcoming：Reed needs the throw of lever of sufficient length just to can guarantee that its elastic force and reliability.Bullet can be caused if lever is too short
Power is excessive, and repeatedly causes plastic deformation or fatigue after deformation.Therefore, installation reed needs sufficiently large space.It is and big
Most optical module structures are compact, do not possess so many space and installed for reed, so structure practicality is not high.
