Description

Technical Field

[0001] This invention relates to the mechanical structure of optoelectronic modules in the field of optical communication technology, and in particular to an optical module that uses a pull ring for unlocking. Background Technology

[0002] With the rapid development of the Internet, cloud computing, and big data, the construction of IT infrastructure data centers is accelerating, and 5G networks are being piloted in developed cities. Consequently, 25G SFP28 optical modules are being used in the construction of 5G signal base stations. Besides 5G networks, 25G SFP28 optical modules are also widely used in 25G data centers. The optimal input / output (I / O) performance and fiber capacity of the 25G SFP28 optical module are 2.5 times that of 10G Ethernet, and it has higher port density. It can also save operating costs by reducing the number of ToR switches and cables. The SFP-25G-SR optical module is mainly used in 25G data centers and 5G fronthaul CPRI / eCPRI networks. The SFP-25G-SR optical module uses a hot-pluggable SFP28 package, operates at a wavelength of 850nm, and is a full-duplex transceiver module. Its maximum speed is up to 25.78Gbps, with dual LC optical ports, and a maximum transmission distance of 70m (OM3) or 100m (OM4) through multimode fiber. The SFP-25G-SR optical module is favored by data centers for its ability to provide cost-effective 25G network solutions.

[0003] In devices with increasingly dense ports, the space available for module locking and unlocking mechanisms is becoming increasingly limited, requiring simpler and more convenient unlocking operations. At the same time, color-coded indicators for different module types need to be more prominent, and pull rings should display more module information to facilitate quick identification among numerous modules.

[0004] Currently, there are two main types of locking and unlocking mechanisms for SFP+ and SFP28 series modules:

[0005] The length of the first type of module pull ring will not exceed the module body, and its movement trajectory is circular. That is, the pull ring drives other unlocking parts to work by rotating, thereby unlocking the optical module.

[0006] The second type of module has a pull ring that is longer than the module body and moves in a straight line. That is, the pull ring drives other unlocking parts to work through linear movement, thereby unlocking the optical module.

[0007] The first unlocking method requires a relatively large assembly space for surrounding components during the pull ring rotation process. In densely packed equipment, the pull ring may interfere with other modules or panels during unlocking, preventing it from rotating to the correct position and thus failing to unlock. The color code for this type of module is usually made on the pull ring handle; when the module is installed in the equipment, the color code cannot be identified unless the pull ring is rotated to the optical port position. The second unlocking method, such as the module locking and unloading device in Chinese patent CN201711326704.8, involves pulling a long pull ring when the module needs to be unlocked. The pull ring is on the top surface of the module, and the unlocking device is on the bottom surface. Applying a downward force to pull the pull ring generates a large bending moment, resulting in very high friction on the sliding block of the unlocking mechanism, making it prone to jamming and preventing unlocking.

[0008] In view of the above, how to overcome the defects of the existing technology and solve the above-mentioned technical problems is a difficult problem to be solved in this technical field. Summary of the Invention

[0009] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a novel, more reliable, and more widely applicable optical module with a pull ring unlock mechanism. This module offers the following features: it is suitable for optoelectronic modules that limit the maximum height after the pull ring is rotated; it is suitable for communication equipment with high-density ports; the module's color markings are more intuitive and easy to identify; it allows for fiber optic cable insertion and removal, reducing fiber end-face contamination and facilitating maintenance and use; the module unlocking is smoother and without jamming; unlocking only requires flicking the pull ring vertically, and the pull ring automatically returns to its original position when the external force is released, making it convenient and simple.

[0010] The embodiments of the present invention adopt the following technical solutions:

[0011] This invention provides an optical module with a pull ring unlocking mechanism, comprising a pull ring, a base, a retaining cover, a brake pad, a spring, and a spring. The spring is disposed within the base, and a spring is disposed on each side of the base. The two side walls of the pull ring are connected to the base via shaft holes, and each side wall of the pull ring presses against a spring. The brake pad is rotatably disposed within the base, with one end positioned above the spring and the other end positioned on the pull ring. The retaining cover engages with the base and limits the movement of the brake pad. The brake pad has a protrusion. When the pull ring is not subjected to external force, the protrusion extends from the surface of the base. When the end of the pull ring is subjected to external force and moves upward, the pull ring rotates around the shaft hole, and the two side walls of the pull ring compress the spring downward, causing the brake pad to rotate and compress the spring. At this time, the protrusion retracts from the surface of the base. When the external force at one end of the pull ring is removed, the brake pad returns to its original position under the action of the spring force, and the pull ring returns to its original position under the action of the spring force.

[0012] Furthermore, the base includes an inclined cavity and a deep groove disposed in the middle of the head; the inclined cavity is symmetrically distributed with a first circular groove and a second circular groove, a first base slot and a second base slot; a first retaining wall is disposed on the outer side of the first circular groove, and a second retaining wall is disposed on the outer side of the second circular groove; the end face of the base head is symmetrically distributed with a first buckle and a second buckle, a first boss and a second boss, a first rotating shaft and a second rotating shaft, the first rotating shaft having a first chamfer and the second rotating shaft having a second chamfer; on the base head, a third buckle and a fourth buckle are symmetrically distributed in the opposite direction to the inclined cavity, the side of the third buckle having a third chamfer and the side of the fourth buckle having a fourth chamfer.

[0013] Furthermore, the top of the spring is provided with a sliding arc, and the bottom of the spring is provided with a flat support; during installation, the spring is placed in the deep groove of the base, and the flat support of the spring is supported at the bottom of the deep groove.

[0014] Furthermore, each of the spring pieces has a locking position at one end and an elastic arm at the other end; during installation, the locking position of one of the spring pieces is locked onto the first locking wall of the base, and the locking position of the other spring piece is locked onto the second locking wall of the base.

[0015] Furthermore, the pull ring includes a first locking hole and a second locking hole symmetrically distributed on the left and right sides. A support arm is provided in the middle of the pull ring, and an inclined surface is provided above the support arm. A first stop and a second stop are symmetrically arranged on both sides of the inclined surface. A first pressing arm is provided on the outer side of the first stop, and a second pressing arm is provided on the outer side of the second stop. A plastic handle is provided below the pull ring. During installation, the two arms of the pull ring are guided by the first chamfer and the second chamfer of the base and are engaged with the outer front end of the base. The first locking hole and the second locking hole are respectively fitted onto the first rotating shaft and the second rotating shaft of the base. The first pressing arm and the second pressing arm of the pull ring respectively press down on the elastic arm of one of the spring pieces.

[0016] Furthermore, one end of the brake pad is provided with a protruding support surface, and a protrusion is provided on the protruding support surface. One end of the brake pad is provided with a sliding groove, and the other end opposite to the sliding groove is provided with a sliding point. The brake pad has a first rotating shaft and a second rotating shaft symmetrically distributed on the left and right sides of its middle portion. During installation, the brake pad is placed in the inclined cavity of the base, and the first rotating shaft and the second rotating shaft of the brake pad are respectively placed in the first circular groove and the second circular groove of the base. The sliding groove of the brake pad is held in place by the sliding arc of the spring, and the sliding point of the brake pad is located on the inclined surface of the pull ring.

[0017] Furthermore, the front end face of the cover has a first slot and a second slot symmetrically distributed on the left and right sides. The cover has a first fixed arm and a second fixed arm symmetrically distributed in the middle. The cover has a positioning arm on one end face in the middle. The cover has an L-shaped sidewall symmetrically arranged on the left and right sides. The top of one L-shaped sidewall has a third slot, and the top of the other L-shaped sidewall has a fourth slot. The third slot and the fourth slot penetrate the vertical and horizontal directions of their respective L-shaped sidewalls. Reinforcing ribs are provided on both L-shaped sidewalls. During installation, the third slot and the fourth slot of the cover are guided by the third chamfer and the fourth chamfer of the base to lock the third buckle and the fourth buckle of the base. The first slot and the second slot of the cover cooperate with the first buckle and the second buckle of the base, respectively. At this time, the first fixed arm and the second fixed arm of the cover are respectively locked in the first base slot and the second base slot of the base, limiting the first and second rotating shafts of the brake pad from above. The positioning arm of the cover presses down on the protruding support surface of the brake pad.

[0018] Furthermore, the base has a large cavity inside, which houses a circuit board. A top cover is provided above the large cavity and is fixed to the base with screws. A spring frame surrounds both the base and the top cover.

[0019] Furthermore, when the optical module and the cage are assembled, the protrusions on the brake pad lock the cage, and the optical module is in working condition.

[0020] Furthermore, when the optical module is unlocked from the cage, the pull ring is lifted to disengage the protrusion of the brake pad from the cage, and the optical module can be unloaded from the cage by pulling the pull ring.

[0021] Compared with existing technologies, the advantages of this invention are as follows: It provides a novel, more reliable, and more widely applicable optical module with a pull ring unlocking mechanism, suitable for optoelectronic modules that limit the maximum height after the pull ring is rotated; suitable for communication equipment with high-density ports; the module color markings are more intuitive and easy to identify; it allows for fiber optic plugging and unplugging, reducing fiber end-face contamination and facilitating maintenance and use; and the module unlocking is smoother and without jamming. Unlocking only requires flicking the pull ring vertically, and the pull ring automatically returns to its original position when the external force is released, making it convenient and simple.

They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0050] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] Example 1:

[0052] like Figure 1 As shown, for reference Figure 2 Embodiment 1 of the present invention provides an optical module with a pull ring unlock, including a pull ring 1, a base 2, a retaining cover 3, a brake pad 4, a spring 5, and a spring 6. The spring 6 is disposed inside the base 2. One spring 5 is disposed on each side of the base 2. The two side walls of the pull ring 1 are connected to the base 2 via shaft holes, and each side wall of the pull ring 1 presses against one spring 5. The brake pad 4 is rotatably disposed inside the base 2, with one end of the brake pad 4 positioned above the spring 6 and the other end positioned on the pull ring 1. The retaining cover 3 is engaged with the base 2. The brake pad 4 is positioned such that it has a protrusion 4-4. When the pull ring 1 is not subjected to external force, the protrusion 4-4 extends from the surface of the base 2. When the end of the pull ring 1 is subjected to external force and moves upward, the pull ring 1 rotates around the shaft hole, and the two side walls of the pull ring 1 compress the spring 5 downward, causing the brake pad 4 to rotate and compress the spring 6. At this time, the protrusion 4-4 retracts from the surface of the base 2. When the external force at one end of the pull ring 1 is removed, the brake pad 4 returns to its original position under the elastic force of the spring 6, and the pull ring 1 returns to its original position under the elastic force of the spring 5. With the above settings, this embodiment of the invention can lock or unlock the optical module by lifting or lowering the pull ring 1 to drive the brake pad 4 to move, thereby using the locking structure on the brake pad. It should be noted that the "up" and "down" in the above description are based on... Figure 1 , Figure 25 The directions shown as up and down, if changed to as... Figure 2 If the directions are as shown, then "up" in the above description needs to be changed to "down," and "down" needs to be changed to "up."

A plastic handle 1-1 is provided below the pull ring 1. During installation, the two arms of the pull ring 1 pass through the first locking hole 1-4 and the second locking hole 1-2 of the base 2. A chamfer 2-7 and a second chamfer 2-13 guide the pull ring 1, which is inserted into the outer front end of the base 2. The first locking hole 1-4 and the second locking hole 1-2 are respectively fitted onto the first rotating shaft 2-8 and the second rotating shaft 2-12 of the base 2. For example, the first locking hole 1-4 is fitted with the first rotating shaft 2-8, and the second locking hole 1-2 is fitted with the second rotating shaft 2-12, so that the pull ring 1 can rotate on the base 2. The first pressing arm 1-5 and the second pressing arm 1-9 of the pull ring 1 respectively press down on the elastic arm 5-2 of the spring piece 5. When the pull ring 1 rotates, the elastic arm 5-2 of the spring piece 5 can apply a rebound force to return the pull ring 1 to its initial position. In this embodiment, a part of the pull ring 1 is a three-sided metal strip with elasticity, which is processed by sheet metal stamping. In this embodiment, the plastic handle 1-1 is set below the pull ring 1 by secondary injection molding to facilitate pulling the pull ring 1.
