Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a detachable optical module pull ring structure and an optical module. Background Art

[0002] The design and manufacturing process of existing optical communication active optical modules, as core components of modern communication technology, have always attracted much attention. Currently, the optical communication active optical modules on the market use the traditional independent parts precision assembly combination method.

[0003] The optical module packaging structure typically includes a pull ring for inserting and removing the module. To distinguish different types of optical modules (e.g., with different speeds and wavelengths), different pull rings are often used for different modules, often with different handle colors. However, since the pull ring is integrated, each time a handle with a different color is needed, the entire pull ring must be redesigned and remolded. This results in poor interchangeability between different pull rings. Furthermore, for optical modules of the same package type, repeated development of new pull ring designs and structural molds is necessary, increasing structural resource costs. Furthermore, the unlocking mechanism on the pull ring is prone to failure due to metal fatigue after long-term use, necessitating replacement. If the pull ring is integrated, failure of the unlocking mechanism requires replacement of the entire pull ring, which also increases material waste during subsequent maintenance.

[0004] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in this technical field. Summary of the Invention

[0026] One of the core components of fiber-optic communications is the conversion of optical and electrical signals. Fiber-optic communications uses information-carrying optical signals to transmit within optical fibers / waveguides. Leveraging the passive transmission properties of light within optical fibers, this technology enables low-cost, low-loss information transmission. Computers and other information processing devices, on the other hand, utilize electrical signals, necessitating the conversion between electrical and optical signals during transmission.

[0027] Optical modules implement the aforementioned photoelectric conversion function in the field of fiber-optic communications. The conversion between optical and electrical signals is the core function of optical modules. Optical modules achieve electrical connections to external host computers via gold fingers on the circuit board. Key electrical connections include power supply, I2C signals, data transmission signals, and grounding. This gold finger-based electrical connection has become standard in the optical module industry, necessitating the circuit board as a necessary technical feature of most optical modules.

[0028] Figure 1 This is a diagram of the connection relationship of optical communication terminals, taking a hybrid mode optical modem as an example. Figure 1 As shown, the optical communication terminal's connections primarily include an optical network unit (ONU) 1, an optical module 2, an optical fiber 3, and a network cable 4. One end of the optical fiber 3 connects to a remote server, while one end of the network cable 4 connects to a local information processing device. The connection between the local information processing device and the remote server is completed by the connection between the optical fiber 3 and the network cable 4. The connection between the optical fiber 3 and the network cable 4 is completed by the ONU 1 with the optical module 2.

[0029] The optical port of the optical module 2 is connected to the optical fiber 3, establishing a bidirectional optical signal connection with the optical fiber 3; the electrical port of the optical module 2 is connected to the optical network unit 1, establishing a bidirectional electrical signal connection with the optical network unit 1; the optical module 2 realizes the mutual conversion between optical signals and electrical signals, thereby realizing the establishment of a connection between the optical fiber 3 and the optical network unit 1; in a certain embodiment, the optical signal from the optical fiber 3 is converted into an electrical signal by the optical module 2 and then input into the optical network unit 1, and the electrical signal from the optical network unit 1 is converted into an optical signal by the optical module 2 and input into the optical fiber 3.

[0030] The optical network unit 1 has a network cable interface 11 for accessing the network cable 4 and establishing a bidirectional electrical signal connection with the network cable 4; the optical network unit 1 has an optical module interface 12 for accessing the optical module 2 and establishing a bidirectional electrical signal connection with the optical module 2; a connection is established between the optical module 2 and the network cable 4 through the optical network unit 1. In a certain embodiment, the optical network unit 1 transmits the signal from the optical module 2 to the network cable 4, and transmits the signal from the network cable 4 to the optical module 2. The optical network unit 1 acts as the host computer of the optical module 2 to monitor the operation of the optical module 2.

[0031] At this point, a bidirectional signal transmission channel is established between the remote server and the local information processing device through the optical fiber 3, the optical module 2, the optical network unit 1 and the network cable 4.

[0032] Common information processing devices include routers, switches, and electronic computers. The optical network unit 1 is the host computer of the optical module 2, providing data signals to the optical module 2 and receiving data signals from the optical module 2. Common host computers of the optical module 2 also include optical line terminals.

[0033] The optical network unit has a circuit board, and a cage is set on the surface of the circuit board; an electrical connector is set in the cage for connecting to the electrical port of the optical module such as the gold finger; a radiator is set on the cage, and the radiator has a protruding structure such as fins to increase the heat dissipation area.

[0034] The optical module 2 is inserted into the optical network unit 1 . Specifically, the electrical port of the optical module 2 is inserted into the electrical connector in the cage, and the optical port of the optical module 2 is connected to the optical fiber 3 .

[0035] The cage is located on the circuit board, wrapping the electrical connector on the circuit board in the cage; the optical module 2 is inserted into the cage, and the cage fixes the optical module 2. The heat generated by the optical module 2 is conducted to the cage through the optical module 2 housing and finally diffused through the heat sink on the cage.

[0036] Combine Figure 2 The optical module 2 generally includes a packaging shell 5 and an unlocking handle, a circuit board, a light emitting component and a light receiving component.

[0037] The packaging shell 5 may include an upper shell and a lower tube shell, and the upper shell covers the lower tube shell to form a wrapping cavity with two openings; the outer contour of the wrapping cavity is generally a square body. In a certain embodiment of the present disclosure, the lower tube shell includes a main board and two side panels located on both sides of the main board and perpendicular to the main board; the upper shell includes a cover plate, and the cover plate covers the two side panels of the upper shell to form a wrapping cavity; the upper shell may also include two side walls located on both sides of the cover plate and perpendicular to the cover plate, and the two side walls are combined with the two side panels to realize that the upper shell covers the lower tube shell.

[0038] The two openings can be two openings at both ends in the same direction, or two openings in different directions; one of the openings is an electrical port, and the gold finger of the circuit board extends from the electrical port and is inserted into a host computer such as the optical network unit 1; the other opening is an optical port, which is used for external optical fiber 3 to connect to the optical transmitting component and optical receiving component inside the optical module 2; optoelectronic devices such as the circuit board, optical transmitting component and optical receiving component are located in the encapsulated cavity.

[0039] The upper shell and the lower shell are combined to form an assembly method, which makes it easy to install components such as circuit boards, optical emitting components and optical receiving components into the shell. The upper shell and the lower shell form the outermost packaging protection shell of the optical module 2. The upper shell and the lower shell are generally made of metal materials, which are conducive to electromagnetic shielding and heat dissipation.

[0040] The unlocking handle is located on the outer wall of the cavity / lower tube shell and is used to achieve a fixed connection between the optical module 2 and the host computer, or to release the fixed connection between the optical module 2 and the host computer.

[0041] The unlocking handle has a snap-fit ​​structure that matches the cage of the host computer; by pulling the end of the unlocking handle, the unlocking handle can be moved relative to the surface of the outer wall; the optical module 2 is inserted into the cage of the host computer, and the snap-fit ​​structure of the unlocking handle fixes the optical module 2 in the cage of the host computer; by pulling the unlocking handle, the snap-fit ​​structure of the unlocking handle moves accordingly, thereby changing the connection relationship between the snap-fit ​​structure and the host computer, thereby releasing the snap-fit ​​relationship between the optical module 2 and the host computer, so that the optical module 2 can be pulled out of the cage of the host computer.

[0042] The main improvement of the embodiment of the present invention is to improve the unlocking handle of the optical module, separating the unlocking handle into a pull ring handle and a pull ring body. At the same time, the packaging shell needs to be adaptively adjusted. The structure composed of the pull ring handle, the pull ring body and the packaging shell is called a pull ring structure. The pull ring structure of the embodiment of the present invention is explained below with reference to the accompanying drawings. 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.

[0043] Embodiment 1: Embodiment 1 of the present invention provides a detachable optical module pull ring structure, such as Figure 2 and Figure 3 As shown, it includes a packaging shell 5, a pull ring handle 6 and a pull ring body 7; the pull ring body 7 is slidably connected to the packaging shell 5; the pull ring handle 6 includes a handle body 61 and a connecting structure 62, and the connecting structure 62 is used to install the handle body 61 on the pull ring body 7, and allows the pull ring body 7 to slide relative to the packaging shell 5 by pulling the handle body 61, wherein the pull ring handle 6 and the pull ring body 7 are two independent components, so they can be disassembled.

[0044] This embodiment provides a pull ring handle 6 and a pull ring body 7 separately so that the two can be disassembled and separated. Therefore, when it is necessary to distinguish different optical modules, it is only necessary to design pull ring handles 6 of different colors without redesigning the pull ring body 7, thereby reducing material and manpower consumption. Moreover, when the unlocking structure of the optical module fails after long-term use, only the pull ring body 7 can be replaced without replacing the pull ring handle 6, further reducing material waste.

[0045] In a specific application scenario, such as Figure 4As shown, the pull ring body 7 includes a first slide arm 71 , a second slide arm 72 and a cover plate 73 connecting the first slide arm 71 and the second slide arm 72 ; the first slide arm 71 and the second slide arm 72 are respectively arranged on both sides of the cover plate 73 .

[0046] like Figure 5 and Figure 6 As shown, a first sliding groove 51 is provided on the first side surface of the encapsulating shell 5 , and a second sliding groove 52 is provided on the second side surface of the encapsulating shell 5 .

[0047] like Figure 7 and Figure 8 As shown, the first slide arm 71 is slidably mounted in the first slide groove 51 on the first side of the packaging shell 5, and the second slide arm 72 is slidably mounted in the second slide groove 52 on the second side of the packaging shell 5, and the cover plate 73 is located on the upper surface or lower surface of the packaging shell 5. The slide directions of the first slide groove 51 and the second slide groove 52 are both horizontal, that is, the movement direction when the optical module is unlocked and the movement direction when the optical module is reset. This achieves the limitation of the two sides of the pull ring body 7 (that is, the first side and the second side of the packaging shell 5) and allows the pull ring body 7 to slide along the first slide groove 51 and the second slide groove 52. Figure 8 In the embodiment, the cover plate 73 is located on the upper surface of the packaging shell 5 . In actual use, it is also feasible that the cover plate 73 is located on the lower surface of the packaging shell 5 .

[0048] Furthermore, in order to realize the unlocking function of the pull ring body 7, as Figure 9 As shown, the first sliding arm 71 is further provided with a first locking protrusion 713 and a first unlocking structure 714 facing the packaging shell 5; Figure 10 As shown, the packaging shell 5 is provided with a first accommodating cavity 81 at a position on the first side surface corresponding to the first locking protrusion 713 , and a first unlocking groove 511 is provided in the first sliding groove 51 .

[0049] like Figure 11 As shown, the first accommodating cavity 81 is used to accommodate the first elastic component 82 and the first locking protrusion 713; the first locking protrusion 713 abuts against the end of the first elastic component 82 away from the handle body 61; the first unlocking structure 714 is slidably installed in the first unlocking groove 511.

[0050] Similarly, if Figure 9 As shown, the second sliding arm 72 is further provided with a second locking protrusion 723 and a second unlocking structure 724 facing the packaging shell 5; Figure 12As shown, the packaging shell 5 is provided with a second accommodating cavity 91 at a position on the second side surface corresponding to the second locking protrusion 723 , and a second unlocking groove 521 is provided in the second sliding groove 52 .

[0051] The second accommodating cavity 91 is used to accommodate the second elastic component 92 and the second locking protrusion 723. The second locking protrusion 723 abuts against the end of the second elastic component 92 away from the handle body 61. The second unlocking structure 724 is slidably mounted in the second unlocking groove 521. In actual use, the first elastic component 82 and the second elastic component 92 are both springs.

[0052] In a preferred embodiment, the first sliding arm 71 is further provided with a first window 711 at a position corresponding to the first elastic component 82, and a second window 712 is provided at a position corresponding to the first locking protrusion 713. The first window 711 is used to observe from the outside whether the first elastic component 82 in the first accommodating cavity 81 is properly installed, and the second window 712 is used to observe from the outside whether the first locking protrusion 713 is correctly inserted into the first accommodating cavity 81 and abuts against the first elastic component 82. Similarly, the second sliding arm 72 is further provided with a third window 721 at a position corresponding to the second elastic component 92, and a fourth window 722 is provided at a position corresponding to the second locking protrusion 723. The third window 721 is used to observe from the outside whether the second elastic component 92 in the second accommodating cavity 91 is properly installed, and the fourth window 722 is used to observe from the outside whether the second locking protrusion 723 is correctly inserted into the second accommodating cavity 91 and abuts against the second elastic component 92.

[0053] In a practical application scenario, the cover plate 73 is located on the upper surface of the packaging shell 5, and as Figure 9 As shown, the first sliding arm 71 is also provided with a first connecting portion 715, which is used to connect with the cover plate 73, and the shape of the first connecting portion 715 fits the outer shape design of the packaging shell 5; similarly, the second sliding arm 72 is also provided with a second connecting portion 725, which is used to connect with the cover plate 73, and the shape of the second connecting portion 725 fits the outer shape design of the packaging shell 5.

[0054] In an optional embodiment, as Figure 13 As shown, the connection structure 62 includes a hook structure 621 , a first slide plate 622 and a second slide plate 623 ; the hook structure 621 , the first slide plate 622 and the second slide plate 623 are connected to the handle body 61 .

[0055] like Figure 10 and Figure 12As shown, a third sliding groove 53 is provided on the first side surface of the packaging shell 5 corresponding to the inner side of the first sliding arm 71 , and a fourth sliding groove 54 is provided on the second side surface of the packaging shell 5 corresponding to the inner side of the second sliding arm 72 .

[0056] like Figure 14 and Figure 15 As shown, the first slide plate 622 is slidably installed in the third slide groove 53, and the second slide plate 623 is slidably installed in the fourth slide groove 54; the slideways of the third slide groove 53 and the fourth slide groove 54 are both horizontal.

[0057] like Figure 16 As shown, the hook structure 621 hooks the cover plate 73 toward the handle body 61, so that when the handle body 61 is pulled, the pulling force is transmitted to the cover plate 73 through the hook structure 621, thereby driving the handle body 61 to slide. In this embodiment, the assembled complete packaging structure is as shown. Figure 17 As shown, the first slide arm 71 is located on the outside of the first slide plate 622, and the second slide arm 72 is located on the outside of the second slide plate 623, thereby forming a slideway that is closed on four sides (i.e., the upper and lower sides and both sides of the first slide arm 71 and the upper and lower sides and both sides of the second slide arm 72). While allowing the first slide plate 622 to slide in the third slide groove 53 and allowing the second slide plate 623 to slide in the fourth slide groove 54, it also serves to limit the pull ring handle 6 in both sides.

[0058] The hook structure 621 hooks the cover plate 73 toward the handle body 61 , which may be hooking the cover plate 73 away from the edge of the handle body 61 .

[0059] In an optional embodiment, the hook structure 621 includes a plate body and a hook provided at one end of the plate body; the other end of the plate body is connected to the handle body 61, and the opening of the hook faces the direction of the handle body 61, as shown in FIG. Figure 18 As shown, it should be noted that the direction of the opening of the hook toward the handle body 61 means that the opening is necessarily open in the direction toward the handle body 61, and does not mean that the opening is necessarily closed in other directions. In actual use, any hook that can make the cover plate 73 receive the pulling force from the handle body 61 is within the protection scope of this embodiment. In an actual application scenario, the hook can be a second plate 6212 vertically arranged relative to the first plate 6211, such as Figure 19As shown, the hook structure 621 includes a first plate 6211 and a second plate 6212; one end of the first plate 6211 is connected to the handle body 61, and the second plate 6212 is vertically arranged at the other end of the first plate 6211; the first plate 6211 is parallel to the cover plate 73, and the second plate 6212 is arranged in the direction of the cover plate 73, thereby forming a hook with a 90° opening to hook the cover plate 73. Figure 16 shown.

[0060] exist Figure 16 In the embodiment, the first plate 6211 is located above the cover plate 73, and the second plate 6212 faces vertically downward. Alternatively, the first plate 6211 is located below the cover plate 73, i.e., a gap is reserved between the cover plate 73 and the packaging shell 5. When the first plate 6211 is located in the gap between the cover plate 73 and the packaging shell 5, the second plate 6212 vertically hooks onto the cover plate 73. Furthermore, the first plate 6211 has a certain degree of elasticity, thereby enabling it to be mounted on the cover plate 73.

[0061] In a preferred embodiment, Figure 16 and Figure 20 As shown, the cover plate 73 is provided with a slot 731, and the second plate 6212 is inserted into the slot 731 to hook the cover plate 73 through the slot 731; wherein, the slot 731 is provided in the middle area of ​​the cover plate 73, or at the edge of the cover plate 73 away from the handle body 61 (at the Figure 20 (center is right side).

[0062] The middle area of ​​the cover plate 73 refers to the area except the edge of the cover plate 73 close to the handle body 61 (in the middle area of ​​the cover plate 73). Figure 20 Positions other than the left side (center), Figure 20 The example in which the card slot 731 is arranged at the edge of the cover plate 73 away from the handle body 61 is presented. Figure 22 The example in which the card slot 731 is arranged in the middle area of ​​the cover plate 73 is presented.

[0063] In a preferred embodiment, Figure 21 As shown, a first concave arc 7311 and a second concave arc 7312 are respectively provided on both sides of the slot 731. The openings of the first concave arc 7311 and the second concave arc 7312 are facing the side away from the handle body 61 (i.e., the right side). The first concave arc 7311 and the second concave arc 7312 are tear notches of sheet metal stamping to facilitate subsequent processing.

[0064] When the first plate 6211 is located above the cover plate 73, the cover plate 73 is located in the gap between the first plate 6211 and the packaging shell 5; in an optional embodiment, the depth of the second plate 6212 is greater than the thickness of the cover plate 73 so as to better hook the cover plate 73. At the same time, a fifth sliding groove 55 is provided at a position of the packaging shell 5 corresponding to the second plate 6212. The fifth sliding groove 55 is used to provide a sliding space for the second plate 6212. Figure 23 and Figure 24 shown.

[0065] In a preferred embodiment, Figure 25 and Figure 26 As shown, the first side surface of the first plate body 6211 is provided with a first side plate 6213, and the second side surface of the first plate body 6211 is provided with a second side plate 6214; the first side plate 6213 and the second side plate 6214 clamp the packaging shell 5, thereby further realizing the limitation of the two sides of the handle body 61 to ensure the stability of the overall structure formed by the installation.

[0066] When the first plate 6211 is located above the cover plate 73, the installation order of the corresponding overall packaging structure should be as follows: first install the pull ring body 7 on the packaging shell 5, and then install the pull ring handle 6. Since the first slide arm 71 is located on the outside of the third slide groove 53 and the second slide arm 72 is located on the outside of the fourth slide groove 54, after the pull ring body 7 is installed, the third slide groove 53 and the fourth slide groove 54 are closed all around (i.e., the top and bottom and both sides), that is, the outside of the third slide groove 53 and the outside of the fourth slide groove 54 are blocked by the pull ring body 7. In order to enable the first slide plate 622 to be installed in the third slide groove 53 and the second slide plate 623 to be installed in the fourth slide groove 54, as shown in FIG. Figure 27 and Figure 28 As shown, the third slide groove 53 is provided with a first opening 531 facing the handle body 61, so that the first slide plate 622 can be inserted into the third slide groove 53 from the first opening 531. In addition, in order to facilitate installation, the third slide groove 53 includes a first portion 532 close to the first opening 531 and a second portion 533 away from the first opening 531; the height of the second portion 533 (i.e. Figure 28 h2) matches the height of the first slide plate 622, and the height of the first opening 531 (ie Figure 28 h1) is higher than the height of the second portion 533. Figure 28In the figure, h1>h2 is expressed, and the height of the first part 532 decreases gradually from the first opening 531 toward the second part 533 until it is the same height as the second part 533, thereby forming a tunnel with a large entrance and a small depth, so that the first slide 622 can slide from the tunnel into the second part 533, and the second part 533, which matches the height of the first slide 622, serves to limit the first slide 622 in the up and down directions, wherein the length of the second part 533 is greater than the length that the pull ring handle 6 needs to be pulled when the optical module is unlocked.

[0067] like Figure 29 As shown, the fourth slide groove 54 and the third slide groove 53 are designed based on the same concept, that is, the fourth slide groove 54 is provided with a second opening 541 facing the handle body 61, so that the first slide 622 can be inserted into the fourth slide groove 54 through the second opening 541. The fourth slide groove 54 includes a third portion 542 close to the second opening 541 and a fourth portion 543 away from the second opening 541. The height of the fourth portion 543 matches the height of the second slide 623. The height of the second opening 541 is greater than the height of the fourth portion 543. The height of the third portion 542 decreases from the second opening 541 to the fourth portion 543 until it reaches the same height as the fourth portion 543. The length of the fourth portion 543 is greater than the length required to pull the pull ring handle 6 when unlocking the optical module.

[0068] When the first plate 6211 is located below the cover plate 73 , that is, in the gap between the cover plate 73 and the packaging shell 5 , the pull ring handle 6 and the pull ring body 7 can be kept relatively fixed before being installed together in the packaging shell 5 .

[0069] It should be noted here that the packaging shell 5 generally includes an upper shell and a lower tube shell, and the upper shell is covered on the lower tube shell to form the packaging shell 5. In this embodiment, all structures provided on the packaging shell 5, including the first slide groove 51, the second slide groove 52, the third slide groove 53, the fourth slide groove 54 and the fifth slide groove 55, can be independent structures provided on the upper shell or the lower tube shell, or can be formed by covering part of the structure in the upper shell with part of the structure in the lower tube shell. The specific implementation is obtained by those skilled in the art based on demand analysis, and this embodiment is not limited here.

[0070] In some preferred embodiments, the multiple corners of the hook structure 621 are designed as arc angles, and the connecting edges are also designed as arc angles, such as Figure 30As shown, the first plate 6211 and the second plate 6212 are connected using a first curved plate 6215, the first plate 6211 and the first side plate 6213 are connected using a second curved plate 6216, and the first plate 6211 and the second side plate 6214 are connected using a third curved plate to form an arc-shaped connecting edge.

[0071] like Figure 31 As shown, the first slide plate 622 includes a fifth portion 6221 close to the handle body 61 and a sixth portion 6222 away from the handle body 61. The height of the fifth portion 6221 (ie Figure 31 h3) is smaller than the height of the sixth portion 6222 (i.e. Figure 31 h4 in ), that is Figure 31 h3 is smaller than h4, and the lower edge of the fifth part 6221 is higher than the lower edge of the handle body 61, and the lower edge of the sixth part 6222 is lower than the lower edge of the handle body 61.

[0072] like Figure 32 As shown, the packaging housing 5 is further provided with a limiting protrusion 56 at a position corresponding to the edge of the cover plate 73 away from the handle body 61 to limit the position of the handle body 61. Furthermore, the wall surface where the first opening 531 is located is designed as an inclined surface, namely a first ramp 57, so that the first slide 622 slides along the first ramp 57 into the first opening 531 and enters the third chute 53 from the first opening 531. Similarly, the wall surface where the second opening 541 is located is designed as a second ramp, so that the first slide 622 slides along the second ramp into the second opening 541 and enters the fourth chute 54 from the second opening 541.

[0073] In actual use, it can be understood as follows: a protrusion is provided on each side of the packaging shell 5, and one surface of the protrusion facing the handle body 61 is designed as an inclined surface, forming the first inclined platform 57 or the second inclined platform. A portion of the outer side of the protrusion is hollowed out from the outer side of the first inclined platform 57 to form the third sliding groove 53, and the hollowed-out portion of the first inclined platform 57 forms the first opening 531. Similarly, a portion of the outer side of the protrusion is hollowed out from the outer side of the second inclined platform to form the fourth sliding groove 54, and the hollowed-out portion of the second inclined platform forms the second opening 541.

[0074] When installing the pull ring handle 6, Figure 33 As shown, the first slide 622 is aligned with the position of the first opening 531, and the second slide 623 is aligned with the position of the second opening 541, and is inserted in a manner of tilting downward at a certain angle (such as Figure 33 As shown by the arrow in the figure), until the first slide 622 enters the second part 533 and the second slide 623 enters the fourth part 543, the level is gradually restored (as shown in the figure). Figure 34 ), as indicated by the arrow in Figure 34 It should be noted that for the sake of clarity of the accompanying drawings, Figure 33 and Figure 34 The pull ring body 7 is not shown, but it does not mean that it does not exist. In actual use, when the pull ring handle 6 is installed, the hook structure 621 is elastically deformed and pressed against the cover plate 73 of the pull ring body 7 until the installation is completed. The hook structure 621 hooks the card slot 731, as shown in FIG. Figure 16 and Figure 17 As shown, when the pull ring handle 6 needs to be removed, the pull ring body 7 together with the pull ring handle 6 is pulled to the left (i.e. Figure 34 In the opposite direction of the arrow in the middle), while keeping the pull ring body 7 still, push the hook structure 621 upward and continue to pull the pull ring handle 6 to the left, so that the hook structure 621 is disengaged from the slot 731 and then continue to pull until Figure 33 The first inclined platform 57 and the second inclined platform ensure that even if the spacing between the first slide 622 and the second slide 623 or the spacing between the third chute 53 and the fourth chute 54 cannot be completely aligned due to processing errors, they can still be compatible, so that the first slide 622 can smoothly enter the third chute 53 and the second slide 623 can enter the fourth chute 54.

[0075] It should be noted that, in this embodiment, the directions or positional relationships indicated by “upper”, “lower”, “both sides”, “horizontal direction”, etc. are described based on the horizontal placement of the optical module.

[0076] In this embodiment, the QSFP (Quad Small Form-factor Pluggable) package is mainly used for demonstration. However, it should be noted that this embodiment is applicable to any package structure of an optical module that includes a pull ring, including but not limited to the QSFP package, the OSFP (Octal Small Form-factor Pluggable) package, and the corresponding different models of derivative versions of the above packages, such as the QSFP+ package, which is an extended version of the QSFP package, the QSFP28 package, the QSFP56 package, the QSFP-DD package, etc.
