Problems solved by technology

[0004] The unlocking mechanism of the existing optical module is usually based on the lever principle to drive the lock to realize unlocking, that is, the lock is located at one end of the lever, and the other end of the lever is connected to the pull ring. When unlocking, the lock is driven downward by lifting the pull ring. In this way, when the optical module is unlocked, it not only needs to be pulled out along the pull-out direction of the module, but also needs to be driven along the lever rotation direction to unlock it. If the lever is not rotated in place Immediately pull out, easy to cause damage to the lock head and cage
[0005] The application number is: 201010153763.1 Chinese invention patent application "SFP optical module unlocking device and SFP optical module using the unlocking device", which discloses an SFP that can be unlocked by directly applying force along the direction in which the optical module is pulled out Optical module unlocking device, the unlocking device of the SFP optical module uses the arc-shaped unlocking piece to directly lift up the locking piece on the top of the optical module shell when pulling out, thereby driving the locking hole on the locking piece to rise, and making the lock head out of the locking hole , the unlocking can be achieved by pulling directly along the disengagement direction of the module, but it still has the following disadvantages: when unlocking, the lock piece needs to be bent to the height of the lock head, so that the lock head can be released from the lock hole on the lock piece, Therefore, a large unlocking force is required when unlocking, and the operation is inconvenient, and each component is subjected to a large force, and the locking piece is prone to failure after being bent many times

Embodiment 1

[0036] Such as figure 1 As shown, the unlocking mechanism of an SFP optical module in this embodiment includes an SFP optical module provided with an optical port 1 and an electrical port 2. Unlock and pull out from the cage.

[0037] For the process of locking and unlocking the optical module and the cage of the switch, please refer to figure 2 , image 3 and Figure 4 : When the optical module is locked with the cage of the switch, the locking head 4 protrudes from the inside of the optical module through the lock hole 3 to the top surface of the optical module, and is locked with the cage of the switch, thereby preventing the optical module from being released from the cage. When the optical module needs to be unlocked from the cage of the switch, the lock head 4 is retracted from the lock hole 3 to the inside of the optical module, and the clamp connection between the lock head 4 and the cage is released, and the optical module can be released. The module is pulled ou...

Embodiment 2

[0044] Such as Figure 1 to Figure 8 As shown, in the unlocking mechanism of the SFP optical module in this embodiment, the middle part of the rotating arm 5 is hinged with the optical module, the lock head 4 is arranged at one end of the rotating arm 5, and the other end of the rotating arm 5 can be connected with the elastic reset device, and the lever The mode of drive lock head 4 resets. The elastic resetting device is a bend 7 provided on the optical module. The bend 7 is punched by the housing 10 and then bent upward. When unlocking, the arm 5 is pressed against the bend 7 . Using the top surface of the optical module housing 10 after punching and bending 7 as an elastic reset mechanism not only has good elasticity, but also has a simple structure and takes up little space, which is beneficial to the arrangement of the internal space of the optical module.

[0045] Such as Figure 9 As shown, in this embodiment, the bend 7 is located on the housing 10 above the end of ...

Embodiment 3

[0050] Such as Figure 1 to Figure 9 As shown, in the unlocking mechanism of the SFP optical module in this embodiment, a pull plate 12 is provided between the module base 9 and the housing 10, the pull plate 12 is fixedly connected to the unlocking slider 6, and the upper surface of the module base 9 is provided with a chute 11 , the bottom surface of the pull plate 12 is slidably matched with the top surface of the chute 11, and the pull plate 12 arranged on the chute 11 drives the translation of the unlocking slider 6, which is beneficial to guide the moving direction of the unlocking slider 6. The pull plate 12 is connected with a pull rod 13 on the side close to the optical port 1, and the pull rod 13 is exposed at one end of the optical port 1 of the optical module. Pull out the pull plate 12 and drive the unlocking slider 6 to move to unlock. The pull plate 12 is provided with a through groove 12b, and the rotating arm 5 is arranged inside the through groove 12b, so as...

Abstract

The invention provides an unlocking mechanism of SFP (small form pluggable) optical modules. The unlocking mechanism comprises an optical module with an optical port and an electric port; a locking hole is arranged at the top part of the optical module; a locking head which is convex towards the top part of the optical module through the locking hole is arranged on the optical module; a rotary arm is hinged inside the optical module; an elastic reset device is arranged between the rotary arm and the optical module; the locking head is arranged on the rotary arm; the locking head is provided with an inclined plane close to one side of the electric port; an unlocking slide block is arranged inside the locking hole; the unlocking slide block can slide inside the locking hole; and the unlocking slide block is arranged above the inclined plane; and when in unlocking, the unlocking slide block is contacted with the inclined plane, and the locking head is pushed into the optical module through the inclined plane. As the optical module can be unlocked only by exerting a force to the inclined plane so as to push the rotary arm hinged inside the optical module to rotate downwards, the resistance in unlocking is small, the unlocking force necessary for unlocking is small, and the operation is convenient.

Description

technical field [0001] The invention relates to a hot-swappable small package module, in particular to an unlocking mechanism of an SFP optical module. Background technique [0002] The main function of the optical transceiver module is to realize photoelectric / electro-optical conversion, referred to as optical module, usually composed of optoelectronic devices, functional circuits and optical interfaces, etc., is an important part of the optical fiber communication system, according to different packaging forms, mainly divided into SFP, GBIC , XFP, etc. Among them, the SFP optical module is a hot-swappable small package module. The volume of the SFP optical module is half that of the GBIC module, and more than double the number of ports can be configured on the same panel, while other functions are basically the same as the GBIC optical module. [0003] The connection between the SPF optical module and the switch cage is detachable, and the SPF optical module can be plugge...
