Description

Technical Field

[0001] The utility model relates to the field of optical modules, and in particular to an SFP DAC-AOC sinking unlocking structure. Background Art

[0002] There are many ways to unlock the traditional optical module and the cage, such as the optical communication module unlocking structure recorded in the application number 2020106929159, which adopts a sinking unlocking structure. The top surface of the unlocking piece used in the unlocking structure is a plane (according to the application document Figure 1 , Figure 2 The angle shown is the top surface. Figure 3 , Figure 4 The angle shown is the bottom surface, and the top surface is used as an example for explanation). When the unlocking piece and the cage are in the locked state, the top surface of the unlocking piece is lower than or flush with the top surface of the shell, and when the unlocking piece and the cage are switched from the unlocked state to the unlocked state, the rear end of the unlocking piece will be higher than the top surface of the shell, see the patent Figure 4 , which creates the risk of the agreed size NG. In addition, the unlocking structure is also equipped with a spring at the front end of the unlocking piece, which uses the spring force to push the front end of the unlocking piece upward, so that the front end of the unlocking piece and the cage remain in a locked state. However, the spring is prone to failure after long-term use, further causing the locking between the unlocking piece and the cage to fail. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a SFP DAC-AOC sinking unlocking structure to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model provides a technical solution to the above technical problems as follows: an SFP DAC-AOC sunken unlocking structure, comprising: a shell and a pull ring, an unlocking piece is arranged in a mounting groove on the top surface of the rear end of the shell, the middle part of the unlocking piece is rotatably connected to the shell via a rotating shaft, the front end of the pull ring is located below the unlocking piece and cooperates with the unlocking piece, a reset spring with two ends respectively pressed against the pull ring and the shell is arranged in the mounting groove along the moving direction of the pull ring, the top surface of the middle and rear sections of the unlocking piece is a first inclined surface inclined upward from back to front, the top surface of the front section of the unlocking piece is a first plane, and during the switching process between the unlocking piece and the cage in the unlocked and locked states, the entire top surface of the unlocking piece is lower than or flush with the top surface of the rear end of the shell.

[0005] The beneficial effects of the utility model are:

[0006] The top surfaces of the middle and rear sections of the unlocking piece are designed to be a first inclined surface inclined upward from the back to the front, while the top surface of the front section of the unlocking piece is still maintained as a first plane. Compared with the prior art in which the entire top surface of the unlocking piece is simply a plane, the top surface of the unlocking piece is divided into two sections in the utility model, so that the entire top surface of the unlocking piece is always lower than or flush with the top surface of the rear end of the shell during the process of switching between the locked state and the unlocked state between the unlocking piece and the cage, thereby avoiding the agreement size NG.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the front end of the pull ring has a first platform and a second platform connected in sequence from back to front, the top surface of the first platform is higher than the top surface of the second platform, the rear side surface of the first platform is a third inclined surface inclined upward from back to front, the bottom of the unlocking piece has an accommodating cavity in the middle and rear sections, the rear wall surface of the accommodating cavity is a fourth inclined surface inclined upward from back to front, the front side surface of the second platform is a fifth inclined surface inclined downward from back to front, and the middle bottom of the unlocking piece has a sixth inclined surface inclined downward from back to front;

[0009] When the unlocking member and the cage are in a locked state, the first platform enters the accommodating cavity, and under the elastic force of the return spring, the fifth inclined surface of the pull ring is closely attached to the sixth inclined surface of the unlocking member;

[0010] When the pull ring is pulled back to switch the unlocking member and the cage from a locked state to an unlocked state, the first platform gradually slides backward from the accommodating cavity and presses against the rear end bottom of the unlocking member to make the front end of the unlocking member sink and the rear end tilt up so that the unlocking member and the cage are completely unlocked.

[0011] The above-mentioned further beneficial effect is that the structure can complete the switching of the pull ring and the unlocking member between the locked state and the unlocked state, and can prevent the unlocking member from rotating downward in the locked state, thereby eliminating the need to equip the front end of the unlocking member with a spring, while also satisfying the requirement of keeping the unlocking member and the cage in a stable locked state.

[0012] Furthermore, a third platform is provided on the front side of the second platform, the top surface of the second platform is higher than the top surface of the third platform, and when the unlocking member and the cage are in a locked state, the third platform supports the unlocking member.

[0013] A further beneficial effect of the above arrangement is that when the unlocking member and the cage are in a locked state, the third platform supports the unlocking member to prevent the unlocking member and the cage from being locked and failing.

[0014] Furthermore, the area where the unlocking member contacts the third platform is a plane.

[0015] A further beneficial effect of the above is that a sufficient contact area can be provided to ensure stability.

[0016] Furthermore, there is an arc transition surface between the front wall surface of the accommodation cavity and the front section of the unlocking member.

[0017] The beneficial effect of the above is that when there is relative movement between the unlocking member and the pull ring, the smoothness of the movement can be ensured.

[0018] Furthermore, the first platform and the second platform are arranged in a stepped manner, and the stepped groove bulges upward in the area below the first platform.

[0019] The beneficial effect of the above is that when the unlocking member and the cage are in an unlocked state, the second platform can be blocked by the bulge to prevent the pull ring from detaching from the housing and ensure the safety of the entire structure.

[0020] Furthermore, an avoidance cavity is formed in the middle area of the pull ring, a blocking block extending into the avoidance cavity is provided at the bottom of the installation groove, the return spring is arranged in the avoidance cavity, one end of the return spring abuts against the front side surface of the blocking block, and the other end of the return spring abuts against the front wall surface of the avoidance cavity.

[0021] The beneficial effect of the above is that on the one hand, the safety of the return spring during operation can be ensured, and on the other hand, the pull ring can be prevented from detaching from the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0032] Embodiment 1

[0033] As Figure 1 , Figure 2 , Figure 6 , Figure 7 shown, a sinking unlocking structure for SFP DAC - AOC includes: a housing 1 and a pull ring 2. An unlocking member 3 is arranged in an installation groove 110 on the rear end top surface of the housing 1. The middle part of the unlocking member 3 is rotationally connected to the housing 1 through a rotation axis 4. The front end of the pull ring 2 is located below the unlocking member 3 and cooperates with the unlocking member 3. A return spring 5 that abuts against the pull ring 2 and the housing 1 at both ends is arranged in the installation groove 110 along the moving direction of the pull ring 2;

[0034] On the top surface of the middle and rear sections of the unlocking member 3 is a first inclined surface 310 that slopes obliquely upward from the rear to the front, while the top surface of the front section of the unlocking member 3 is a first flat surface 320. Compared with the prior art where the entire top surface of the unlocking member 3 is only a simple flat surface, in the present utility model, the top surface of the unlocking member 3 is divided into two sections, so that the entire top surface of the unlocking member 3 is always lower than or flush with the rear end top surface of the housing 1 during the process of switching between the locked state and the unlocked state of the unlocking member 3 and the cage, thereby avoiding non - compliant protocol dimensions.

[0035] Embodiment 2

[0036] As Figures 1 to 7 shown, this embodiment is a further improvement on Embodiment 1, specifically as follows:

[0037] The front end of the pull ring 2 has a first platform 210, and the front side of the first platform 210 has a second platform 220. The top surface of the first platform 210 is higher than the top surface of the second platform 220. The dimension of the first platform 210 in the width direction is adapted to the dimension of the installation groove 110 in the width direction, and the dimension of the second platform 220 in the width direction is adapted to the dimension of the installation groove 110 in the width direction;

[0038] The rear side surface of the first platform 210 is a third inclined surface 211 inclined upward from the rear to the front, and the bottom of the unlocking member 3 has a receiving cavity 330 in the middle and rear sections. The rear wall surface of the receiving cavity 330 is a fourth inclined surface 331 inclined upward from the rear to the front. In the process of switching from the locked state to the unlocked state, the third inclined surface 211 and the fourth inclined surface 331 cooperate to facilitate the first platform 210 to gradually slide backward from the receiving cavity 330;

[0039] The front side of the second platform 220 is a fifth inclined surface 221 which is inclined downward from the back to the front, and the middle bottom of the unlocking member 3 is provided with a sixth inclined surface 340 which is inclined downward from the back to the front. In the locked state, the fifth inclined surface 221 cooperates with the sixth inclined surface 340 to facilitate locking the front end of the unlocking member 3 with the cage. At the same time, the cooperation between the fifth inclined surface 221 and the sixth inclined surface 340 can also prevent the unlocking member 3 from rotating downward, thereby eliminating the need to equip the front end of the unlocking member 3 with a spring, and at the same time, it is also sufficient to ensure that the unlocking member 3 and the cage are stably locked.

[0040] When the pull ring 2 is pulled back to switch the unlocking member 3 and the cage from the locked state to the unlocked state, the first platform 210 gradually slides backward from the accommodating cavity 330 and presses against the bottom of the rear end of the unlocking member 3 to make the front end of the unlocking member 3 sink and the rear end tilt up so that the unlocking member 3 and the cage are unlocked. When the pulling force applied to the pull ring 2 is released, the return spring 5 in the deformed state is reset, which will prompt the pull ring 2 to move toward the front end and reset, thereby allowing the unlocking member 3 to rotate in the opposite direction, causing the rear end of the unlocking member 3 to sink and the front end to tilt up, so that the front end of the unlocking member 3 and the cage can re-enter the locked state. When the unlocking member 3 and the cage are in the locked state, the first platform 210 enters the accommodating cavity 330, and under the elastic force of the return spring 5, the fifth inclined surface 221 of the pull ring 2 is close to the sixth inclined surface 340 of the unlocking member 3.

[0041] Example 3

[0042] like Figure 4 , Figure 6 , Figure 7 As shown, this embodiment is a further improvement on the basis of embodiment 2, and the details are as follows:

[0043] The front side of the second platform 220 has a third platform 230 , and the top surface of the second platform 220 is higher than the top surface of the third platform 230 . When the unlocking member 3 and the cage are in a locked state, the third platform 230 supports the unlocking member 3 to prevent the unlocking member 3 from being locked with the cage and failing.

[0044] Furthermore, the area where the unlocking member 3 contacts the third platform 230 is a plane, and may have a sufficient contact area to ensure stability.

[0045] Example 4

[0046] likeFigure 5 , Figure 6 , Figure 7 As shown in Figure 7 , this embodiment is a further improvement based on Embodiment 2 or 3, and the specific details are as follows:

[0047] There is an arc transition surface 350 between the front wall surface of the accommodation cavity 330 and the front section of the unlocking member 3, which can ensure the smoothness of the movement when there is relative movement between the unlocking member 3 and the pull ring 2.

[0048] Embodiment 5

[0049] As Figure 4 , Figure 6 , Figure 7 As shown in Figure 4 , Figure 6 , and Figure 7 , this embodiment is a further improvement based on Embodiment 2, 3, or 4, and the specific details are as follows:

[0050] The first platform 210 and the second platform 220 are arranged in a stepped manner, and the stepped groove bulges upward in the area below the first platform 210. When the unlocking member 3 and the cage are in the unlocked state, the bulge can block the second platform 220 to prevent the pull ring 2 from detaching from the housing 1 and ensure the safety of the entire structure.

[0051] Embodiment 6

[0052] As Figure 2 , Figure 4 As shown in Figure 2 and Figure 4 , this embodiment is a further improvement based on Embodiment 2, 3, or 4, and the specific details are as follows:

[0053] A cavity 240 is formed in the middle area of the pull ring 2. A blocking block 120 extending into the cavity 240 is provided at the bottom of the installation groove 110. The return spring 5 is arranged in the cavity 240. One end of the return spring 5 abuts against the front side surface of the blocking block 120, and the other end of the return spring 5 abuts against the front wall surface of the cavity 240. This design can, on the one hand, ensure the safety of the return spring 5 during its operation, and on the other hand, prevent the pull ring 2 from detaching from the housing 1.

[0054] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
