DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 12 An embodiment of the present invention provides an AOC optical module, including a pull strap 1, and an unlocking member 2 having an unlocking end 21 and a driving end 20. The pull strap 1 drives the driving end 20 to make the unlocking end 21 sink, and the unlocking end 21 escapes from the cage 7 to unlock; the unlocking member 2 is also provided with a secondary unlocking structure for when the unlocking fails. In this embodiment, by designing a secondary unlocking structure on the unlocking member 2, the use space inside the optical module does not need to be occupied, and the secondary unlocking can be quickly and conveniently achieved when the unlocking fails, so as to complete the unlocking and escape of the optical module from the cage 7. Specifically, the secondary unlocking structure is provided on the unlocking member 2, and will not affect the chamber in the shell 3. The shell 3 is composed of two parts: an upper cover 30 and a base 31, which are buckled together to form a space for installing a circuit board and a space for installing an adapter. If the existing method of increasing the depth or amplitude of the unlocking end 21 of the unlocking member 2 to ensure that the unlocking end 21 is released from the triangular slot of the cage 7 at one time is adopted, a deeper stroke for the unlocking end 21 to sink must be designed, which will occupy the space of the chamber and affect the design of the internal circuit board and the design of the entire optical module. The present application sets the secondary unlocking structure on the unlocking member 2. The unlocking member 2 itself is movable outside the shell 3 and will not affect the chamber inside the shell 3. Secondly, the horizontal space outside the shell 3 can be used. This part of the space can be simply realized according to the structural size design at the optical port 35. For example, the middle part of the drawstring 1 at the optical port 35 is designed to be shorter, and a gap is left in the pressing sheet 4 for the installation of the secondary unlocking structure.

[0030] See also Figures 1 to 12, the secondary unlocking structure includes a grabbing end 22 provided on the driving end 20, the grabbing end 22 moves in the same direction as the driving end 20, and when the grabbing end 22 moves, the unlocking end 21 escapes from the cage 7. In this embodiment, the secondary unlocking structure is refined into the grabbing end 22. When in use, the grabbing end 22 is grabbed and pulled upward, that is, pulled in the direction of the upward tilt of the driving end 20. The grabbing end 22 will pry the spring piece next to the triangular slot of the cage 7. After the spring piece is tilted upward, the unlocking end 21 can be smoothly escaped from the triangular slot. Under normal circumstances, the unlocking failure is that the unlocking end 21 cannot be smoothly escaped from the triangular slot of the cage 7, and only a small part may not be escaped, which will cause the unlocking failure. At this time, prying the spring piece of the cage 7 can make the unlocking end 21 completely escape from the slot, thereby successfully unlocking. Preferably, the grabbing end 22 can be designed as an integral part with the unlocking member 2, which can save costs. The grabbing end 22 can be refined, and it can be an L-shaped grabbing sheet, which is designed to be L-shaped, and a step structure can be formed to avoid other structures of the optical module. Of course, it can also be directly designed as an inclined sheet structure, which can also play the role of contacting the shrapnel of the cage 7 when it is pulled up. A clamping hole 220 can be designed on the grabbing sheet, which is convenient for inserting tweezers into the clamping hole 220 and then pulling up the grabbing end 22. Of course, the grabbing end 22 can also be directly pried from the edge with tweezers. Preferably, different grabbing forms can also be designed, such as designing a hook ring, so that the grabbing end 22 can be pulled up by a rod that can be inserted into the hook ring, or the grabbing end 22 can be designed as a magnetic structure, and a magnet can be used to absorb the grabbing end 22 and then pull it up, or a bonding area can be designed on the grabbing end 22, and the grabbing end 22 can be pulled up by bonding, such as Velcro. The above methods are all feasible methods and can be designed as needed.

[0031] See also Figures 1 to 12 The optical module further comprises a housing 3 which can be partially inserted into the cage 7, and the drawstring 1 is slidably arranged on the portion of the housing 3 which is not inserted into the cage 7. In this embodiment, the housing 3 is provided with the drawstring 1, and the housing 3 comprises an upper cover 30 and a base 31, which are described in detail in the above embodiment and will not be repeated here.

[0032] See also Figures 1 to 12 The unlocking member 2 has a rotating shaft 23 rotatably disposed on the housing 3. In this embodiment, the rotating shaft 23 can be used to realize the upward and downward movement of the driving end 20 and the unlocking end 21 of the unlocking member 2 by utilizing the lever principle, and the rotating shaft 23 is similar to a fulcrum. Of course, in addition to the method of using the rotating shaft 23, the sinking of the unlocking end 21 can also be realized by moving up and down.

[0033] See also Figures 1 to 12The housing 3 is provided with a protrusion 32 facing the driving end 20. When the head of the drawstring 1 moves to the protrusion 32, the head of the drawstring 1 is lifted up to lift up the driving end 20. In this embodiment, the lifting of the driving end 20 of the unlocking member 2 is achieved by the cooperation between the drawstring 1 and the protrusion 32 on the housing 3. The protrusion 32 is specifically designed on the outer surface of the upper cover 30. Specifically, the head of the pull strap 1 is two drive strips 10, and the drive strips 10 have a three-section structure, in which the first section 100 is straight, the second section 101 is arched relative to the upper surface of the second section 101, and the lower surface is recessed upward, and the third section 102 is tilted downward, and the structure on the shell 3 is exactly matched with the structure of the drive strip 10. When the third section 102 moves to the protrusion 32 of the shell 3, the third section 102 will be pushed up. Since the drive end 20 is facing the protrusion 32, the third section 102 will also push up the drive end 20 on the protrusion 32, thereby realizing the upward tilt of the drive end 20, and the unlocking end 21 of the unlocking member 2 sinks to disengage from the triangular slot.

[0034] See also Figures 1 to 12 , the shell 3 is provided with a pressing sheet 4, and the pressing sheet 4 is provided with a limit block 40 on the side facing the shell 3, and the drawstring 1 is provided with a slide groove 33 in which the limit block 40 slides. In this embodiment, by designing the pressing sheet 4, on the one hand, it can play the purpose of pressing the structure below it, and on the other hand, the designed limit block 40 can cooperate with the slide groove 33 on the drawstring 1 to limit the moving stroke of the drawstring 1. The limit block 40 can be designed at two locations, each of which has two limit blocks 40 arranged oppositely, and the limit block 40 can slide in the slide groove 33, and the length of the slide groove 33 can be designed to limit the sliding stroke. The slide groove 33 is an open groove with one side open, which can cooperate with the upper cover 30 to form a closed rectangular groove. Preferably, the pressing sheet 4 can be fixed with the convex ridge on the shell through the window designed thereon, or it can be locked on the shell by screws, and the screws here can also be used for the locking cooperation of the upper cover and the base of the shell. The limit block 40 can be a structure bent on the pressing sheet 4, and the pressing sheet 4 can be a sheet metal part for easy bending.

[0035] See also Figures 1 to 12 , the optical module also includes a spring 5 for resetting the pull strap 1. In this embodiment, the spring 5 is designed so that after pulling the pull strap 1, the pull strap 1 can be reset by hand under the action of the spring 5 by loosening the pull strap 1. A groove can be designed on the pull ring for setting the spring 5. Due to the action of the pressing plate 4, there is no need to worry that the spring 5 will fly up. Preferably, a blocking block 34 is designed on the upper cover 30, which can abut against one side of the spring 5, and the other side of the spring 5 abuts against the groove wall of the groove. Preferably, the blocking block 34 also extends into the groove, which can make the structure more compact.

[0036] See also Figures 1 to 12, the unlocking member 2 is detachably mounted on the housing 3. In this embodiment, by detachably mounting the unlocking member 2 on the housing 3, different unlocking members 2 can be replaced as needed, for example, a sinking mode of the unlocking end 21 of the unlocking member 2 can be selected, different grabbing ends 22 can be selected, etc.

[0037] See also Figures 1 to 12 An EMI shrapnel 6 is provided at the housing 3 near the optical port 35 to play an electromagnetic shielding role.
