Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connector, in particular to an adapter assembly and an optical communication device. BACKGROUND

[0002] The adapter assembly is an important device in the optical communication device. The adapter assembly includes a mechanical transmission (MT) to multi-fiber push on (MPO) adapter (also referred to as MT / MPO adapter) and an MT plug. The MT to MPO adapter has an MT port and an MPO port at two ends. The MT port is used to connect with the MT plug, and the MPO port is used to connect with the MPO plug. The MT plug includes an MT optical fiber and an MT clip, and the MT optical fiber is connected to the MT port through the MT clip.

[0003] In order to save costs, the MT to MPO adapter in the current adapter assembly is made of plastic. However, the MT to MPO adapter made of plastic cannot shield electromagnetic waves inside the optical communication device, which has a safety hazard. SUMMARY

[0004] The present application provides an adapter assembly and an optical communication device. The technical solution is as follows:

[0005] In a first aspect, an adapter assembly is provided, which is used to be installed on an opening of a panel. The adapter assembly includes: a MT to MPO adapter, which includes: a flange, an MT port and an MPO port, the MT port and the MPO port are located at two sides of the thickness direction of the flange, and the MPO port is used to connect with an MPO plug; and an MT plug, which includes an MT optical fiber and an MT clip connected with each other, and the MT plug is connected with the MT port; wherein the flange is made of conductive plastic.

[0006] In the adapter assembly provided by the present application, the flange is made of conductive plastic, so that the MT to MPO adapter can realize electromagnetic wave shielding with a large area, and reduce the safety hazard. In addition, the conductive plastic has a certain elasticity, which can reduce the wear of the flange and improve the service life of the flange.

[0007] Optionally, other parts of the MT to MPO adapter except the flange can also be made of conductive plastic.

[0008] For example, the MT port is made of conductive plastic. In this way, the electromagnetic shielding effect of the adapter assembly is further improved. Moreover, because the conductive plastic has a certain elasticity, the wear of the MT port can be reduced, especially the wear of the MT plug and the MT port caused by plugging and unplugging can be effectively reduced, thereby improving the service life of the adapter assembly.

[0009] For example, the MPO port is made of conductive plastic. In this way, the electromagnetic shielding effect of the adapter assembly is further improved. Moreover, because the conductive plastic has a certain elasticity, the wear of the MPO port can be reduced, especially the wear of the MPO plug and the MPO port caused by plugging and unplugging can be effectively reduced, thereby improving the service life of the adapter assembly and the MPO plug.

[0010] In the foregoing embodiments of the present application, the flange, the MT port and the MPO port can be integrally formed by the same conductive plastic. In this way, the manufacturing is facilitated, and the MT-to-MPO adapter as a whole can shield electromagnetic waves. For example, the MT-to-MPO adapter can be manufactured by a mold opening process.

[0011] For example, the conductive plastic includes any one or more of polyether sulfone, polyaniline, polyacetylene or poly (p-phenylene acetylene). For example, the polyether sulfone is PESU-CF30, and the conductivity of the PESU-CF30 can be 50 Siemens per meter (S / m).

[0012] Optionally, at least part of the MT clamp is made of conductive plastic.

[0013] In an optional example, the MT plug is detachably connected to the MT port.

[0014] For example, the MT optical fiber includes a fiber head and a fiber tail, and the MT clamp includes a clamp seat and a guide rod. A first end of the guide rod is fixedly connected to the clamp seat, and a second end of the guide rod is configured to be inserted into a guide hole of the fiber head from an end of the fiber tail close to the guide hole and exposed from an end of the fiber tail away from the guide hole. The first end and the second end of the guide rod are opposite ends of the guide rod. The clamp seat has an accommodation portion inside, and the accommodation portion is configured to allow the fiber tail of the MT optical fiber to pass through after the guide rod is inserted into the guide hole. The clamp seat is made of conductive plastic.

[0015] In the embodiments of the present application, because the clamp seat is made of conductive plastic, after the MT plug is connected to the MT port, the MT plug blocks most of the openings of the MT port through the clamp seat, further improving the electromagnetic shielding effect of the adapter assembly. Moreover, because the conductive plastic has a certain elasticity, the wear of the clamp seat can be reduced, especially the wear of the clamp seat and the MT port caused by plugging and unplugging can be effectively reduced, thereby improving the service life of the adapter assembly.

[0016] In an example, the accommodating portion includes a groove, and the maximum dimension of the opening through which the pigtail passes is less than or equal to 3.5 mm. The area of the opening is 3.25*1.95 mm2. Since the opening area of the groove is greatly reduced relative to the opening area of the MT port. Therefore, after the MT plug is connected with the MT port, the MT plug blocks most of the opening of the MT port through the holder, leaving only a small area of the opening of the groove to leak a small amount of electromagnetic waves, thus effectively improving the shielding effect of electromagnetic waves relative to the conventional adapter assembly.

[0017] In an optional example, the accommodating portion further includes a cover plate detachably connected with the groove. Since the materials of the groove and the cover plate are both conductive plastic, after the two are connected, a smaller space is formed for the pigtail to pass through, further reducing the area through which electromagnetic waves pass, thereby effectively improving the shielding effect of electromagnetic waves. And because the conductive plastic has a certain elasticity, the groove and the cover plate can be tightly clamped by interference fit.

[0018] Optionally, the flange disc has a first fixing hole at each of the two ends in the length direction, and the flange disc is configured to be mounted on the opening of the panel through the first fixing hole. Optionally, the first fixing hole is a threaded hole having an internal thread, or the first fixing hole is not a threaded hole. The flange disc can be mounted on the opening of the panel by a screw with an external thread passing through the first fixing hole and a second fixing hole on the panel. In this way, effective connection of the screw and the threaded hole is achieved, thereby achieving effective fixation of the flange disc and the panel.

[0019] In an example, the panel has a positioning hole, and the flange disc has a guide pin configured to be inserted into the positioning hole on the panel. The guide pin can prevent reverse installation of the MT-to-MPO adapter and ensure stable and accurate connection of the MT-to-MPO adapter and the opening.

[0020] In a second aspect, an optical communication device is provided, comprising:

[0021] a panel having an opening; and the adapter assembly of any one of the first aspect, the MT-to-MPO adapter of the adapter assembly being mounted on the opening of the panel.

[0022] Optionally, the optical communication device further comprises two structural members fixed on both sides of the opening of the panel along the length direction of the opening, and the two ends of the flange disc are fixed with the two structural members to be mounted on the opening of the panel. In an example, the structural member can be a metal member, which can be made of aluminum alloy or steel, etc. The structural member can be riveted with the panel.

[0023] The MT-to-MPO adapter is not directly connected to the panel, but is indirectly connected to the panel through a structural member. The structural member can reduce damage to the panel, strengthen the panel, and prevent panel deformation due to an excessively large panel opening, based on providing a fixed assembly with the MT-to-MPO adapter.

[0024] In an optional example, the optical communication device further includes: a screw; each of the structural members has a second fixing hole; and each of the two ends of the flange plate in the length direction has a first fixing hole. The two ends of the flange plate are fixed to the structural members by the screw passing through the first fixing hole and the second fixing hole.

[0025] Optionally, at least one of the first fixing hole and the second fixing hole is a threaded hole having an internal thread, and the screw has an external thread. In this way, the screw and the threaded hole are effectively connected, thereby effectively fixing the flange plate to the structural member. For example, the first fixing hole is a non-threaded hole, and the second fixing hole is a threaded hole.

[0026] For example, the structural member includes a strip-shaped reinforcing rib. In a first optional example, the strip-shaped reinforcing rib is relatively wide, for example, has a first width, and the second fixing hole can be arranged. In a second optional example, the strip-shaped reinforcing rib is relatively narrow, for example, has a second width, and the second width is less than the first width. The structural member further includes a block-shaped reinforcing rib located at one end of the strip-shaped reinforcing rib and fixedly connected to the strip-shaped reinforcing rib. The block-shaped reinforcing rib is used to arrange the second fixing hole. Compared with the first example, the area of the structural member in the second example is reduced, and the corresponding material is reduced, thereby saving costs.

[0027] Optionally, the panel has a positioning hole, and the flange plate has a guide pin configured to be inserted into the positioning hole of the panel. The arrangement of the guide pin and the positioning hole can prevent the MT-to-MPO adapter from being installed in reverse and ensure stable and accurate connection of the MT-to-MPO adapter to the opening.

[0028] In an optional example, the optical communication device further includes: a shielding gasket located between the MT-to-MPO adapter and the panel. The arrangement of the shielding gasket can achieve effective sealing and reliable contact of the MT-to-MPO adapter to the panel, and better prevent electromagnetic leakage.

[0029] For example, the shielding gasket is a flexible conductive gasket. Due to the elasticity of the flexible conductive gasket, the wear of the MT-to-MPO adapter to the panel can be reduced, and the service life of the two can be improved.

[0030] In a third aspect, the embodiments of the present application further provide an optical communication system, which comprises one or more optical communication devices provided in the second aspect, and the optical communication device can be a high-speed and high-frequency single board such as a router or a switch.

[0031] In the adapter assembly provided by the embodiments of the present application, the flange is made of conductive plastic, so that the MT-to-MPO adapter can realize electromagnetic wave shielding with a large area and reduce safety hazards. In addition, the conductive plastic has a certain elasticity, which can reduce the wear of the flange and improve the service life of the flange.

[0032] In addition, when the MT-to-MPO adapter is connected with the MT card holder with an area of 3.25*1.95 square millimeters, each adapter assembly can realize a shielding capacity of at least 10 dB for electromagnetic waves in a frequency range of 0 to 35 GHz. In this way, even if a panel is installed with multiple adapter assemblies, electromagnetic wave shielding can be effectively realized. Therefore, the optical communication device provided by the embodiments of the present application supports the installation of multiple adapter assemblies, thereby realizing multi-fiber out of the panel and high bandwidth of the panel. For example, a single board can provide 4 to 8 MPO ports. BRIEF DESCRIPTION OF DRAWINGS

[0053] In order to make the principles and technical solutions of the present application clearer, the following will further describe the embodiments of the present application in combination with the drawings.

[0054] Figure 1 is an application environment schematic view of an adapter assembly provided by an embodiment of the present application. The application environment includes:

[0055] MT-to-MPO adapter 1, MT plug 2 and panel 3. The MT-to-MPO adapter 1 is mounted on an opening 31 of the panel 3 of an optical communication device. The optical communication device can be a high-speed and high-frequency single board such as a router single board or a switch single board. The optical communication device can support an in-board optical module or a chip light communication mode. The optical communication device supports an in-board fiber to the MT-to-MPO adapter. The MT-to-MPO adapter 1 has an MT port 11 and an MPO port 12 on two sides in the thickness direction of the MT-to-MPO adapter 1. The MT port 11 is used to connect with the MT plug 2. The MPO port 12 is used to connect with an MPO plug (not shown in the figure). The MT plug 2 includes a connected MT ferrule 21 and MT optical fiber 22. The MT ferrule 21 is sleeved outside the MT optical fiber 22. The outer shape of the MT ferrule 21 matches the inner shape of the MT port 11 (for example, the shapes are consistent or partially consistent) to achieve effective insertion of the MT plug 2 and the MT port 11.

[0056] The adapter assembly includes the MT-to-MPO adapter 1 and the MT plug 2. The MT-to-MPO adapter 1 and the MT plug 2 can be fixedly connected or detachably connected.

[0057] In order to save costs, the MT-to-MPO adapter in the current adapter assembly is made of plastic. The MT-to-MPO adapter made of plastic cannot shield electromagnetic waves inside the optical communication device, which has a safety hazard.

[0058] Figure 2 The adapter assembly provided by the embodiment of the present application is a structural schematic diagram of an adapter assembly. The adapter assembly can solve the above problems. The adapter assembly is used to be mounted on an opening of a panel. As shown in Figure 2 The adapter assembly includes:

[0059] The MT-to-MPO adapter 1 includes a flange 10, an MT port 11 and an MPO port 12. The MT port 11 and the MPO port 12 are respectively located on two sides in the thickness direction of the flange 10. The MPO port is used to connect with an MPO plug.

[0060] The MT plug 2 includes a connected MT ferrule 21 and MT optical fiber 22. The MT plug 2 is connected with the MT port 11. For example, the MT plug 2 is fixedly connected with the MT port 11 or is pluggably connected with the MT port 11.

[0061] Optionally, the MT port 11 or the MPO port 12 of the MT-to-MPO adapter can be made of plastic, thereby saving manufacturing costs.

[0062] In the adapter assembly provided in this application embodiment, because the flange is made of conductive plastic, the MT to MPO adapter can achieve electromagnetic wave shielding over a large area, reducing safety hazards. Furthermore, because the conductive plastic has a certain degree of elasticity, it can reduce flange wear and extend the flange's service life.

[0063] Figure 3 This is a schematic diagram of the structure of an MT to MPO adapter 1 provided in an embodiment of this application. Figure 3 In this design, the flange 10 has first fixing holes 101 at both ends along its length y. The flange 10 is configured to be mounted on the opening 31 of the panel 3 through these first fixing holes 101. Optionally, the first fixing hole 101 is a threaded hole with internal threads, or the first fixing hole 301 is not a threaded hole. The flange 10 can be mounted on the opening 31 of the panel 3 by passing a screw with external threads through the first fixing hole and a second fixing hole on the panel. In this way, an effective connection between the screw and the threaded hole is achieved, thereby effectively fixing the flange 10 to the panel 3.

[0064] In one alternative example, the panel 3 has positioning holes, correspondingly, such as Figure 3 As shown, the flange 10 has a guide pin 102 configured to insert into a positioning hole on the panel 3. For example, the guide pin 102 is located on the side of the flange 10 where the MPO port 12 is located. When the MT to MPO adapter is installed on the panel, the MPO port 12 of the MT to MPO adapter is inserted into the opening from one side (also called the inner side of the panel), while the guide pin 102 is inserted into the positioning hole on the panel 3. Then, the MPO port 12 protrudes from the other side of the opening (also called the outer side of the panel). The guide pin 102 prevents the MT to MPO adapter from being installed in reverse, ensuring a stable and accurate connection between the MT to MPO adapter and the opening.

[0065] Optionally, the MT to MPO adapter 1, except for the flange, may be made of plastic or conductive plastic.

[0066] For example, the MT port 11 is made of conductive plastic. This further enhances the electromagnetic shielding of the adapter assembly. Furthermore, because the conductive plastic has a certain degree of elasticity, it reduces wear on the MT port, especially when the MT plug and MT port are pluggable. This effectively reduces wear on the MT plug and MT port during plugging and unplugging operations, thereby extending the lifespan of the adapter assembly.

[0067] For example, the MPO port 12 is made of conductive plastic. In this way, the electromagnetic shielding effect of the adapter assembly is further improved. Moreover, because the conductive plastic has a certain elasticity, the wear of the MPO port can be reduced, especially the wear of the MPO plug and the MPO port caused by plugging and unplugging can be reduced, thereby improving the service life of the adapter assembly and the MPO plug.

[0068] In the foregoing embodiments of the present application, the material of the flange plate 10 and the materials of the MT port 11 and the MPO port 12 can be the same or different. The three can be integrally formed by the same conductive plastic, which is convenient for manufacturing and can realize the shielding of electromagnetic waves by the MT-to-MPO adapter as a whole. For example, the MT-to-MPO adapter 1 can be manufactured by a mold opening process.

[0069] For example, the material of the conductive plastic includes any one or more of the following: polyether sulfone (PESU), polyaniline (PAn), polyacetylene (Pa), or poly (p-phenylene vinylene) (PPv), etc. For example, the polyether sulfone is PESU-CF30, and the conductivity of the PESU-CF30 can be 50 Siemens per meter (S / m).

[0070] Optionally, at least part of the MT clamp 21 is made of conductive plastic. In order to clearly describe the MT clamp 21, the MT optical fiber 22 will be briefly introduced first. Figure 4 is a structural schematic diagram of an MT optical fiber 22 provided by an embodiment of the present application. The MT optical fiber 22 includes an optical fiber head 221 and a pigtail 222 connected to each other, and the optical fiber head 221 has a guide hole 221a thereon.

[0071] The foregoing MT plug and the MT port can be fixedly connected or pluggably connected. Figure 5 is a structural schematic diagram of an MT clamp 21 provided by an embodiment of the present application. The MT clamp 21 can support the pluggable connection of the MT plug and the MT port. The MT clamp 21 includes a clamp seat 211 and a guide rod 212.

[0072] The first end 212a of the guide rod 212 is fixedly connected to the clamp seat 211. The second end 212b of the guide rod 212 is configured to be inserted into the guide hole 221a from the end of the guide hole 221a close to the pigtail and exposed from the end of the guide hole 221a away from the pigtail. That is, the guide rod 212 is inserted into the guide hole 221a along the target direction x in Figure 4 or Figure 5 the guide hole 221a, and the target direction x is parallel to the extension direction of the guide hole. The first end 212a and the second end 212b of the guide rod 212 are opposite ends of the guide rod 212.

[0073] In this embodiment, the number of guide rods 212 matches the number of guide holes 221a. For example, the number of guide rods 212 is equal to the number of guide holes 221a. Since the fiber optic head 221 typically has two guide holes 221a, the MT clip 21 typically includes two guide rods 212.

[0074] The card holder 211 has a receiving part W inside, which is configured to allow the pigtail 222 of the MT optical fiber 22 to pass through after the guide rod 212 is inserted into the guide hole 221a.

[0075] The card holder 211 is made of conductive plastic.

[0076] The MT to MPO adapter's MT port has an opening for connecting to the MT plug. Traditional MT clips are typically made of plastic, which cannot shield electromagnetic waves, causing electromagnetic waves inside the optical communication equipment to leak through this opening.

[0077] In this embodiment, the socket 211 is made of conductive plastic. Thus, after the MT plug is connected to the MT port, the MT plug blocks most of the opening of the MT port through the socket, further improving the electromagnetic shielding of the adapter assembly. Furthermore, because the conductive plastic has a certain degree of elasticity, it can reduce wear on the socket 211, especially when the MT plug and MT port are detachably connected. This reduces wear on the socket 211 and MT port during insertion and removal operations, thereby extending the lifespan of the adapter assembly.

[0078] For example, such as Figure 5 As shown, the receiving portion W may include a groove, the extension direction of which is parallel to the extension direction of the guide rod 212. When the guide rod is inserted into the guide hole, the extension direction of the groove is parallel to the direction in which the guide rod is inserted into the guide hole (i.e., the target direction x). The groove facilitates the passage of the pigtail 222, enabling rapid assembly of the MT clip and the MT optical fiber.

[0079] Optionally, the maximum size of the opening in the groove through which the pigtail 222 passes is less than or equal to 3.5 mm. The plane containing this opening is perpendicular to the extension direction of the groove. The maximum size of the opening is the greater of the depth and width of the groove. Thus, both the depth and width of the groove are less than or equal to 3.5 mm. For example, the width 'a' of the opening is 3.25 mm and the depth 'b' is 1.95 mm. Therefore, the area of ​​the opening is 3.25 * 1.95 square millimeters.

[0080] Figure 6 This is a schematic diagram of the structure of an adapter component provided in an embodiment of this application. Figure 6 Assume that in the adapter assembly, one MT to MPO adapter 1 has an MT plug 2 plugged into its MT port, while the other MT ports are not plugged into MT plugs. And for the reader's convenience, Figure 6The optical fiber in the MT plug 2. Then, as shown in Figure 6 the opening t2 of the groove of the MT ferrule is much smaller than the area of the opening t1 of the MT port, and the area that may leak electromagnetic waves is reduced to the area of the opening t2 when the MT plug 2 is plugged into the MT port, effectively reducing electromagnetic wave leakage. For example, the MT port of the MT-to-MPO adapter has an opening t1 connected with the MT plug, and the area of the opening t1 is usually 6.55*3.55 square millimeters. When the area of the opening t2 is 3.25*1.95 square millimeters, the area of the region that may leak electromagnetic waves is reduced by (6.55*3.55-3.25*1.95) square millimeters.

[0081] Therefore, after the MT plug is connected to the MT port, the MT plug blocks most of the opening of the MT port through the holder, leaving only the opening area of the groove to leak a small amount of electromagnetic waves, thus effectively improving the shielding effect of electromagnetic waves relative to the conventional adapter assembly. For example, when all the MT ports of the MT-to-MPO adapter are connected to the MT ferrule with an opening area of 3.25*1.95 square millimeters, the opening size can effectively prevent electromagnetic wave leakage outside the panel through simulation and actual measurement, achieving a shielding capability of at least 10 dB (decibels) for electromagnetic waves in the frequency range of 0 to 35 GHz (gigahertz) (i.e., at least 10 dB of electromagnetic wave radiation can be reduced), reducing the risk of electromagnetic radiation leakage in high-frequency high-speed single boards, and meeting the electromagnetic compatibility (EMC) access specifications.

[0082] In addition, the MT ferrule provided by the embodiment of the present application has a relatively simple structure and occupies less space, which can realize the miniaturization of the MT plug as a whole and facilitate plugging and unplugging.

[0083] Figure 5 The holder 211 is taken as an example to be described. In actual implementation, the structure of the holder 211 can also have other implementation manners. For example, the holder can be a detachable structure. The holder is arranged as a detachable structure, which can realize the miniaturization of each component of the holder and the replaceability of each component. When a component has a wear problem, the component can be replaced, thereby prolonging the service life of the holder and reducing maintenance costs.

[0084] Figure 7 is another structure diagram of the MT ferrule 21 provided by the embodiment of the present application. As shown in Figure 7 the holder 211 includes a first support seat 211a, a second support seat 211b, and a connecting rod 211c.

[0085] The first support seat 211a and the second support seat 211b are connected through the connecting rod 211c, and the first support seat 211a and the second support seat 211b after being connected are arranged along the extension direction of the guide rod 212. When the guide rod 212 is inserted into the guide hole, the extension direction of the guide rod 212 is parallel to the direction (i.e., the target direction x) in which the guide rod 212 is inserted into the guide hole. Therefore, when the guide rod 212 is inserted into the guide hole, the first support seat 211a and the second support seat 211b are arranged along the target direction x.

[0086] The first support seat 211a has a first sub-groove W1, the second support seat 211b has a second sub-groove W2, and the first sub-groove W1 and the second sub-groove W2 are communicated to form the accommodating portion W after the first support seat 211a and the second support seat 211b are connected through the connecting rod 211c.

[0087] Figure 7 The first support seat 211a and the second support seat 211b are connected through the connecting rod 211c. Since the first support seat and the second support seat are connected through the connecting rod, the special tool is not required for disassembly, and the disassembly efficiency is ensured.

[0088] The first support seat 211a and the second support seat 211b are connected through the connecting rod 211c. Since the first support seat and the second support seat are connected through the connecting rod, the special tool is not required for disassembly, and the disassembly efficiency is ensured.

[0089] In an alternative implementation, the first support seat 211a and the second support seat 211b are fixedly connected (also referred to as static connection) by the connecting rod 211c. In an alternative example, the connecting rod 211c achieves the fixed connection of the first support seat 211a and the second support seat 211b by clamping. For example, a part of the connecting rod 211c is clamped in the first support seat 211a, and the clamped connecting rod 211c and the first support seat 211a are fixed, another part of the connecting rod 211c is clamped in the second support seat 211b, and the clamped connecting rod 211c and the second support seat 211b are fixed. In another alternative example, the connecting rod 211c achieves the fixed connection of the first support seat 211a and the second support seat 211b by screwing. For example, one end of the connecting rod 211c is screwed with the first support seat 211a (for example, the one end of the connecting rod 211c has external threads, the first support seat 211a has a threaded hole, and the screwing of the one end of the connecting rod 211c into the threaded hole can achieve screwing) to achieve the fixed connection of the one end with the first support seat 211a, and the other end of the connecting rod 211c is screwed with the second support seat 211b to achieve the fixed connection of the other end with the second support seat 211b (for example, the other end of the connecting rod 211c has external threads, the second support seat 211b has a threaded hole, and the screwing of the other end of the connecting rod 211c into the threaded hole can achieve screwing). In yet another alternative example, the connecting rod 211c achieves the fixed connection of the first support seat 211a and the second support seat 211b by screwing and clamping. For example, one end of the connecting rod 211c is screwed with one of the first support seat 211a and the second support seat 211b, and the other end of the connecting rod 211c is clamped with the other of the first support seat 211a and the second support seat 211b. Since the first support seat and the second support seat are clamped and / or screwed by the connecting rod, no special tool is needed for disassembly, ensuring the disassembly efficiency.

[0090] In another alternative implementation, the first support seat 211a and the second support seat 211b are movably connected (also referred to as dynamic connection) by the connecting rod 211c.

[0091] In an alternative example, the connecting rod 211c achieves the movable connection of the first support seat 211a and the second support seat 211b by clamping. The first support seat 211a and the second support seat 211b can produce relative movement of a preset distance in the target direction x along the connecting rod 211c.

[0092] For example, a part of the connecting rod 211c is clamped in the first support seat 211a, and another part of the connecting rod 211c is clamped in the second support seat 211b. Wherein, the clamped connecting rod 211c and the first support seat 211a can produce a first distance of relative displacement in the target direction x, and the clamped connecting rod 211c and the second support seat 211b can produce a second distance of relative displacement in the target direction x. The sum of the first distance and the second distance is equal to the preset distance. Alternatively, one end of the connecting rod 211c is fixedly connected (such as clamped or threaded) with one of the first support seat 211a and the second support seat 211b, and the other end of the connecting rod 211c is clamped with the other of the first support seat 211a and the second support seat 211b, and the clamped connecting rod 211c and the other can produce a preset distance of relative displacement in the target direction x.

[0093] Examples, Figure 8 is an exploded schematic view of an MT card holder 21 provided by an embodiment of the present application. Figure 8 The connecting rod 211c includes a rod body c0, and a first clamping portion c1 and a second clamping portion c2 located at both ends of the rod body c0. The first support seat 211a has a first accommodating groove a1, and the second support seat 211b has a second accommodating groove b1; the first accommodating groove a1 is configured to accommodate a part of the connecting rod 211c, and has a third clamping portion a11 clamped with the first clamping portion c1, and the second accommodating groove b1 is configured to accommodate another part of the connecting rod 211c, and has a fourth clamping portion b11 clamped with the second clamping portion c2. Optionally, one of the first clamping portion c1 and the third clamping portion a11 is a clamping protrusion, and the other is a clamping groove; and / or, one of the second clamping portion c2 and the fourth clamping portion b11 is a clamping protrusion, and the other is a clamping groove. Figure 8 The first clamping portion c1 and the second clamping portion c2 are clamping protrusions, and the third clamping portion a11 and the fourth clamping portion b11 are clamping grooves, which are used as examples for illustration, but the structures of the clamping portions are not limited, as long as the clamping portions can realize the clamping function. In an optional example, the shapes of the clamping protrusions and the clamping grooves are matched, and the clamping protrusions can be movably placed in the clamping grooves in the target direction to realize movable clamping in the target direction. For example, the clamping protrusions are columnar clamping protrusions, and the clamping grooves are clamping grooves with columnar cavities. The length of the columnar cavities is greater than the length of the columnar clamping protrusions, so as to leave a part of space for the columnar clamping protrusions to move in the target direction.

[0094] Figure 9 is another exploded schematic view of an MT card holder 21 provided by an embodiment of the present application. Figure 9 The connecting rod 211c includes a rod body c0, and a first clamping portion c1 and a second clamping portion c2 located at both ends of the rod body c0. The first support seat 211a has a first accommodating groove a1, and the second support seat 211b has a second accommodating groove b1; the first accommodating groove a1 is configured to accommodate a part of the connecting rod 211c, and has a third clamping portion a11 clamped with the first clamping portion c1, and the second accommodating groove b1 is configured to accommodate another part of the connecting rod 211c, and has a fourth clamping portion b11 clamped with the second clamping portion c2. Optionally, one of the first clamping portion c1 and the third clamping portion a11 is a clamping protrusion, and the other is a clamping groove; and / or, one of the second clamping portion c2 and the fourth clamping portion b11 is a clamping protrusion, and the other is a clamping groove. Figure 9As shown, on the basis of the movable connection of the first support seat 211a and the second support seat 211b by the connecting rod 211c, the MT card holder 21 can further include an elastic element 213 located in the card seat 211.

[0095] Supposing that the first end 212a of the guide rod 212 is fixedly connected with the first support seat 211a, the second support seat 211b can receive the pushing force in the target direction to realize the plugging of the card seat 211 with the MT port 11. As shown, Figure 5 to Figure 9 As shown, the second support seat 211b has a pressing surface M at the end away from the first support seat 211a, which is used for the operator to exert the pushing force. The pressing surface M can be a plane or a curved surface. When the pressing surface M is a plane, the uniform exertion of the pushing force can be realized. When the pressing surface M is a curved surface, such as a concave surface, the concentrated exertion of the pushing force can be realized.

[0096] Correspondingly, the second support seat 211b is further configured to, after receiving the pushing force F1 in the target direction x, make the elastic element 213 deformed by moving in the target direction x. Correspondingly, the elastic element 213 is configured to, after being deformed, transmit the pushing force F1 to the first support seat 211a and provide an elastic force F2 to the second support seat 211b in the direction opposite to the target direction x. The target direction x is the direction of the plugging of the guide rod with the guide hole. The pushing force F1 can drive the first support seat 211a to drive the guide rod 212 into the MT port, realizing the quick plugging of the MT card holder.

[0097] By setting the elastic element in the card seat, the buffering and force balance during the plugging of the MT plug with the MT port can be realized, the direct collision and wear of the first support seat and the second support seat are avoided, and the stress of the guide rod 212 during the plugging is not too concentrated, so as to reduce the probability of damage of the MT card holder, improve the reliability of the plugging, thereby prolonging the service life of the MT card holder and reducing the maintenance cost.

[0098] In the embodiments of the present application, the assembly relationship of the elastic element 213 with each element in the MT card holder 21 can be various, as long as the transmission of the pushing force F1 and the provision of the elastic force F2 can be realized. Moreover, the type of the elastic element 213 can be various. In some optional examples, it can be a compression spring. In another optional example, it can be a spring sheet. The embodiments of the present application do not limit the type of the elastic element, as long as the corresponding elastic force can be provided.

[0099] As shown, Figure 8 or Figure 9As shown, the first receiving groove a1 has a first side opening a12, and the second receiving groove b1 has a second side opening b12. The first receiving groove a1 is configured to receive a portion of the connecting rod 211c through the first side opening a12, and the second receiving groove b1 is configured to receive another portion of the connecting rod 211c through the second side opening b12. Figure 8 or Figure 9 In this design, the extension directions of the first side opening a12 and the second side opening b12 are both parallel to the extension direction of the guide rod 212. By providing side openings in the receiving groove, the connecting rod 211c can be assembled into the receiving groove from the side, achieving rapid assembly of the connecting rod and improving assembly and disassembly efficiency.

[0100] Assuming that the receiving groove C is the aforementioned first receiving groove a1 or second receiving groove b1, the corresponding support base is the first support base 211a or the second support base 211b. Figure 10 This is a schematic diagram illustrating the structural principle of a receiving groove C provided in an embodiment of this application. Figure 10 As shown, one end of the receiving groove C has a first opening T1 for one end of the connecting rod 211c to pass through. Assuming that the receiving groove C has a snap-fit ​​groove Q, the end of the connecting rod 211c that connects to the receiving groove is provided with a snap-fit ​​protrusion. Figure 10 In this design, the snap-fit ​​groove Q within the receiving groove C is formed by a baffle Q1 having a second opening T2, the inner wall of the receiving groove C, and the bottom. In practice, the snap-fit ​​groove Q can also be formed by a baffle Q1 having a second opening T2, the inner wall of the receiving groove C, and another baffle. For example, the inner cavity of the receiving groove C can be a cylindrical cavity or a cubic cavity.

[0101] The side wall of the receiving groove C also has a side opening. Figure 10 In this design, the side opening is located on the side of the receiving groove C perpendicular to the paper and facing outwards. This side opening is used for assembling the connecting rod 211c into the receiving groove C, and the snap-fit ​​protrusion of the assembled connecting rod 211c engages with the snap-fit ​​groove. For example, the side opening can be rectangular. Optionally, the support base where the receiving groove C is located further includes a first mounting cover, which is detachably connected to the side opening, such as by snap-fit. After the connecting rod 211c is partially assembled into the receiving groove C, the first mounting cover is installed at the side opening to form at least one end opening with the receiving groove C. Figure 10 The cavity is open at one end and closed on the side. Thus, the first mounting cover can also provide some support and restraint for the connecting rod 211c, reducing displacement of the connecting rod 211c in non-target directions. For example, the shape of the first mounting cover matches at least a portion of the shape of the side opening. For instance, the shape of the first mounting cover is identical to at least a portion of the shape of the side opening.

[0102] The material of the accommodating groove C and the first mounting cover is conductive plastic, so that the accommodating groove C and the first mounting cover can form a smaller space for the connecting rod 211c to pass through, and the area through which electromagnetic waves pass is reduced, thereby effectively improving the shielding effect of electromagnetic waves. Moreover, since the conductive plastic has a certain elasticity, the accommodating groove C and the first mounting cover can be tightly clamped through interference fit.

[0103] It is worth noting that, Figure 10 The structure of the accommodating groove provided herein is only for the convenience of readers to understand, and in actual implementation, the accommodating groove can also have other structures as long as it can effectively accommodate the connecting rod 211c. For example, the clamping groove in the accommodating groove can also be arranged at other positions and not arranged at the bottom of the accommodating groove. Alternatively, a clamping protrusion is arranged in the accommodating groove, and correspondingly, the end of the connecting rod 211c connected to the accommodating groove is provided with a clamping groove.

[0104] In the foregoing embodiment, the elastic element 213 can also not be arranged in the clamping seat 211, and the same function as the elastic element can be achieved through other ways. For example, the foregoing connecting rod 211c is made of elastic material. The connecting rod 211c can not only achieve the function of connecting the first support seat 211a and the second support seat 211b, but also can be deformed after the second support seat 211b is subjected to the pushing force F1 in the target direction x. The pushing force F1 is transmitted to the first support seat 211a, and the elastic force F2 opposite to the target direction x is provided to the second support seat 211b. For example, the elastic material is high-elasticity silica gel. Further, the elastic material can be high-elasticity conductive silica gel. In this way, the shielding effect of the clamping seat on electromagnetic waves can be further improved.

[0105] The foregoing Figure 5 and Figure 7 are described by taking the accommodating portion W as a groove as an example. In the embodiment of the present application, the accommodating portion W can also have other structures as long as it can accommodate the optical fiber.

[0106] Figure 11 is another side view structure schematic diagram of the MT card clamp 21 provided in the embodiment of the present application. The accommodating portion W can further include a cover plate W4 in addition to the groove W3. The cover plate W4 is detachably connected to the groove W3, for example, clamped. The groove W3 has two opposite openings and a side opening. After the optical fiber passes through the groove W3, the cover plate W4 is installed at the side opening of the groove W3 to form a cavity with both ends open and a side closed with the groove W3. In this way, the cover plate W4 can also provide a certain supporting and limiting effect on the optical fiber in the groove W3, thereby reducing the displacement of the optical fiber. The structure of the groove W3 can be Figure 5 or Figure 7 any one of the structures of the grooves in

[0107] Since the material of the groove and the cover plate is conductive plastic, after the two are connected, a smaller space is formed for the fiber to pass through, and the area through which electromagnetic waves pass is further reduced, thereby effectively improving the shielding effect of electromagnetic waves. Moreover, since the conductive plastic has a certain elasticity, the groove and the cover plate can be tightly clamped through interference fit.

[0108] It is worth noting that the connecting rods 211c in the card holder 211 can be one or more. Correspondingly, the number of accommodation grooves in each support seat is equal to the number of connecting rods 211c, so as to realize effective accommodation of the connecting rods 211c. For example, Figure 8 and Figure 9 As shown in the drawings, the card holder 211 includes two connecting rods 211c. Correspondingly, the first support seat 211a has two first accommodation grooves a1, and the second support seat 211b has two second accommodation grooves b1. The two connecting rods 211c are assembled one by one with the two first accommodation grooves a1, and the two connecting rods 211c are assembled one by one with the two second accommodation grooves b1. The two first accommodation grooves a1 are located on both sides of the longitudinal axis section of the support seat. Alternatively, for each of the first support seat 211a and the second support seat 211b, the two accommodation grooves on the support seat are symmetrically arranged with respect to the longitudinal axis section of the support seat, which is parallel to the length direction of the card holder and perpendicular to the width direction of the card holder. For example, when there are two connecting rods on the card holder, and the two connecting rods are symmetrically arranged, the longitudinal axis section is coplanar with the symmetry plane of the two connecting rods.

[0109] When the two first accommodation grooves a1 of the first support seat 211a are symmetrically arranged, and the two second accommodation grooves b1 of the second support seat 211b are symmetrically arranged, the longitudinal axis sections of the two support seats are coplanar, and the two connecting rods 211c after assembly are also symmetric with respect to the longitudinal axis section. In this way, the stress balance of the assembled card holder 211 can be realized, the overall stability is guaranteed, and the reliability of the MT plug and the MT port during the plugging of the MT plug and the MT port can be improved. In the actual implementation of the present application, the two first accommodation grooves a1 can also be not completely symmetrical, for example, Figure 12 In the drawings, one of the two first accommodation grooves a1 is a through groove, which has an opening at the pressing surface M, and the other is a blind groove, which is closed at the pressing surface M. Alternatively, the two first accommodation grooves a1 can both be blind grooves, so as to reduce the opening area and reduce the leakage of electromagnetic waves.

[0110] Further, when the MT card holder 21 further includes an elastic element 213, the number of elastic elements 213 can match the number of connecting rods 211c, for example, equal to the number of connecting rods 211c. For example, Figure 9As shown, if the card holder 211 includes two connecting rods 211c, the MT card holder 21 also includes two elastic elements 213, with the two connecting rods 211c and the two elastic elements 213 assembled one-to-one. Optionally, when the elastic element 213 is a spring, the spring is sleeved on the corresponding connecting rod. When the MT plug is inserted into or removed from the MT port, the two elastic elements 213 can provide cushioning and achieve force balance, ensuring the stability of insertion and removal.

[0111] like Figure 1 As shown, after the MT clip 21 is connected to the MT fiber 22, it is used to insert into the MT port 11 of the MT to MPO adapter 1. The inner wall of the MT port 11 has a slot. Figure 12 This is a schematic diagram of another MT clip 21 provided in this application embodiment. Corresponding to the structure of the MT port 11, the clip holder 211 has clip wings 211d, and clip wings 211d are provided with clips d1. Clips d1 are configured such that: when the clip holder 211 is subjected to a thrust F1 in the target direction x, the clip holder 211 moves toward the clip slot, and clips d1 engage with the clip slot in the MT to MPO adapter 1; when the clip wings 211d are subjected to a pressure F2 toward the clip holder 211, clips d1 release from engagement with the clip slot under the action of the clip wings 211d. This enables quick insertion and removal of the MT plug, that is, quick locking and unlocking of the MT plug and the MT port.

[0112] As mentioned earlier, when the MT clip 21 includes the elastic element 213, the elastic element 213, after deformation, provides a spring force F2 to the second support 211b in the opposite direction to the target x. After the latch d1 engages with the slot in the MT to MPO adapter 1, the elastic element 213 remains deformed, thus still providing the aforementioned spring force F2. Therefore, when the latch d1 disengages from the slot, due to the spring force F2, the second support 211b pops out in the opposite direction to the target x, causing the first support 211a to pop out from the MT port 11. This allows the clip 211 to be quickly pulled out of the MT port 11, and also provides a certain buffering effect for the removal of the clip 211.

[0113] In one alternative configuration, the retaining fin 211d is a double-sided retaining fin. That is, the retaining base 211 has two symmetrically arranged retaining fins.

[0114] In another alternative, the card wing 211d is a single-sided card wing. That is, the card seat 211 has one card wing. By providing a single-sided card wing, quick locking and unlocking of the MT plug and the MT port from one side can be achieved, and the operation space occupied by the plugging operation is small. Moreover, compared with a double-sided card wing, the single-sided card wing also occupies less space. Therefore, under the premise of ensuring pluggability, the space size of the MT card holder is effectively reduced, thereby realizing miniaturization of the MT card holder, facilitating installation of more MT-to-MPO adapters on a single board of an optical communication device, and realizing high-density layout of the MT-to-MPO adapters.

[0115] In actual implementation, the inner wall of the MT port 11 also has a guide groove. Figure 13 is a structural schematic diagram of an MT card holder 21 provided by another embodiment of the present application. Corresponding to the structure of the MT port 11, the card seat 211 has a guide pin 211e configured to be card-connected with the guide groove. The guide pin 211e can play a role of cooperating with the guide groove for guidance, and prevent reverse insertion of the MT card holder, thereby ensuring stable and accurate plugging of the MT plug 2 and the MT port 11.

[0116] In the embodiment of the present application, the first end 212a of the guide rod 212 can be fixedly connected with the card seat 211 in multiple ways. In one alternative, the first end 212a of the guide rod 212 is fixedly connected with the card seat 211 by welding. In another alternative, if the card seat 211 is an integral structure and the guide rod 212 is made of the same material as the card seat 211, the guide rod 212 can be fixedly connected with the card seat 211 by integral molding, that is, the guide rod 212 and the card seat 211 are an integral structure manufactured by the same process. If the card seat 211 is a structure obtained by connecting the first support seat 211a and the second support seat 211b through the connecting rod 211c, and the guide rod 212 is made of the same material as the first support seat 211a, the guide rod 212 can be fixedly connected with the first support seat 211a by integral molding, that is, the guide rod 212 and the first support seat 211a are an integral structure manufactured by the same process. In yet another alternative, the first end 212a of the guide rod 212 is fixedly connected with the card seat 211 by screw connection. In still another alternative, the first end 212a of the guide rod 212 is fixedly connected with the card seat 211 by clamping. The screw connection and clamping can be disassembled without special tools, thereby ensuring disassembly efficiency. Since the guide rod 212 is fixedly connected with the card seat 211 by detachable connection, the guide rod 212 can be disassembled from the card seat 211 when not in use, thereby realizing miniaturization of each component of the MT card holder, reducing the space occupied by the MT card holder when not in use, and realizing replaceability of each component. Since the guide rod has a high wear rate, the guide rod can be replaced when it has problems such as wear, thereby prolonging the service life of the card seat and reducing maintenance costs.

[0117] Figure 14 is a structural schematic diagram of a guide rod 212 and a card seat 211 provided by an embodiment of the present application. Figure 14 The card seat 211 is taken as an example for description, but the structure of the card seat 211 is not limited. The first end 212a of the guide rod 212 has a fifth clamping part d1, the card seat 211 has a sixth clamping part d2, and the guide rod 212 is fixedly connected with the card seat 211 through clamping of the fifth clamping part d1 and the sixth clamping part d2. For example, one of the fifth clamping part d1 and the sixth clamping part d2 is a clamping protrusion, and the other is a clamping groove, but the structure of each clamping part is not limited, as long as the clamping part can realize its clamping function. In an optional example, the shapes of the aforementioned clamping protrusion and clamping groove are matched, and the clamping protrusion can be placed in the clamping groove to realize clamping. For example, the clamping protrusion is a columnar clamping protrusion, and the clamping groove is a clamping groove with a columnar cavity. When the fifth clamping part d1 is a clamping protrusion and the sixth clamping part d2 is a clamping groove, the structures of the clamping protrusion and the clamping groove can refer to the structures of the clamping protrusion and the clamping groove shown in Figure 10 . Figure 10 The difference is that the size difference between the outside of the clamping protrusion and the inside of the clamping groove is small, so that the fixed connection is realized through clamping.

[0118] Figure 14In the fifth embodiment, the fifth clamping part d1 is a clamping groove, and the sixth clamping part d2 is a clamping protrusion. The clamping groove is a ring-shaped groove, and the clamping protrusion is a ring-shaped protrusion. Optionally, the card seat 211 further comprises a third accommodating groove d0, and the clamping protrusion is located in the third accommodating groove d0. The third accommodating groove d0 has a side opening for assembling the first end of the guide rod 212 in the card seat 211, and the clamping groove of the assembled guide rod 212 is clamped with the clamping protrusion. In the example, the side opening can be a rectangular opening. Optionally, the card seat 211 further comprises a second mounting cover which is detachably connected with the side opening, such as clamped. After the first end of the guide rod 212 is assembled in the third accommodating groove d0, the second mounting cover is mounted at the side opening to form a cavity with at least one open end and a closed side with the card seat 211. In this way, the second mounting cover can also provide a certain support and limiting effect on the guide rod 212, reducing the displacement of the guide rod 212 in the non-target direction. In the example, the shape of the second mounting cover matches at least a part of the shape of the side opening. For example, the shape of the second mounting cover is congruent with at least a part of the shape of the side opening. The third accommodating groove d0 and the second mounting cover are both made of conductive plastic, so that the third accommodating groove d0 and the second mounting cover can form a smaller space for the guide rod 212 to pass through after being connected, and also reduce the area through which electromagnetic waves pass, thereby effectively improving the shielding effect of electromagnetic waves. Moreover, since the conductive plastic has a certain elasticity, the third accommodating groove d0 and the second mounting cover can be tightly clamped by interference fit.

[0119] Further, Figure 14 Suppose the card seat 211 is a structure obtained by connecting the first support seat 211a and the second support seat 211b through the connecting rod 211c. When the first support seat 211a simultaneously has the first accommodating groove a1 and the third accommodating groove d0, the two accommodating grooves can be communicated, thereby simplifying the manufacturing process. Moreover, if the card seat 211 comprises a first mounting cover which is detachably connected with the first accommodating groove a1, and a second mounting cover which is detachably connected with the third accommodating groove d0, the two mounting covers can be integrated, that is, the functions of the two mounting covers are realized by one mounting cover, thereby simplifying the manufacturing process and improving the disassembly efficiency.

[0120] The MT card clamp provided by the embodiments of the present application can realize the assembly of the MT card clamp and the MT optical fiber by fixing the guide rod on the card seat and then passing the pigtail from the accommodating part of the card seat. Therefore, the special tool for disassembly is not needed, and the disassembly efficiency is effectively improved. Moreover, the structure of the MT card clamp is relatively simple, and the MT card clamp occupies less space, so that the overall miniaturization of the MT plug can be realized. Moreover, the MT card clamp can be plugged and unplugged, and is detachably connected with the MT optical fiber, so that the assembly of the single board before the optical communication equipment is shipped and the rapid maintenance of the devices in the single board after the optical communication equipment is shipped can be facilitated.

[0121] As mentioned above, when the card holder of the MT card holder 21 is detachable, the card holder and the guide rod are also detachable. Figure 15 is a schematic diagram of the disassembly of the MT card holder 21 provided by the embodiment of the present application. Figure 12 As shown in the figure, the first support seat 211a, the second support seat 211b, the connecting rod 211c, the guide rod 212 and the elastic element 213 are obtained by disassembling the MT card holder 21. These components can be repaired and replaced, thereby prolonging the service life of the MT card holder and reducing the maintenance cost. Moreover, the volume of each component is relatively small, thereby reducing the space occupation. Figure 15

[0122] It is worth noting that the foregoing embodiment only takes the detachable MT plug as an example to describe the MT plug, and the MT plug can also be implemented in other manners in actual implementation. For example, the MT card holder in the MT plug includes a base and a cover plate, and the base and the cover plate are fixed by screws and then sleeved on the fiber head of the MT optical fiber, so as to realize the fixed connection of the MT card holder and the MT optical fiber. For another example, the MT card holder and the MT optical fiber can also be fixed and connected in a manner of gluing. In these manners, the MT card holder can be made of the conductive plastic as described above.

[0123] In an optional manner, the adapter assembly further includes a shielding gasket capable of shielding electromagnetic waves, and the shielding gasket is located between the MT-to-MPO adapter 1 and the panel 3. By arranging the shielding gasket, the MT-to-MPO adapter and the panel can be effectively sealed and reliably contacted, and electromagnetic leakage can be better prevented.

[0124] In an example, the shielding gasket is a flexible conductive gasket. Since the flexible conductive gasket has a certain elasticity, the wear of the MT-to-MPO adapter 1 and the panel 3 can be reduced, and the service life of the two is improved.

[0125] In summary, in the adapter assembly provided by the embodiment of the present application, since the flange is made of conductive plastic, the MT-to-MPO adapter can shield electromagnetic waves with a large area, thereby reducing the security risks. Moreover, since the conductive plastic has a certain elasticity, the wear of the flange can be reduced, and the service life of the flange is improved.

[0126] Figure 16 and Figure 17 is a structural schematic diagram of an optical communication device 0 in different states provided by an embodiment of the present application. The optical communication device 0 can be a high-speed and high-frequency single board such as a router single board or a switch single board. The single board can support the communication mode of the on-board optical module or the chip light emission.

[0127] The exploded view of the optical communication device 0 can refer to Figure 1 , which will not be described in detail by the embodiment of the present application. Reference Figure 1 、 Figure 16 ​and Figure 17 The optical communication device 0 comprises:

[0128] A panel 3, the panel 3 has an opening 31.

[0129] An adapter assembly, the adapter assembly comprises an MT-to-MPO adapter 1 and an MT plug 2, the MT-to-MPO adapter 1 is installed on the opening 31. The adapter assembly is any adapter assembly provided by embodiments of the present application. For the convenience of the reader, Figure 16 The MT-to-MPO adapter is not fixed with the opening 31 of the panel 3, and the MT plug 2 is plugged with the MT port 11 of the MT-to-MPO adapter 1. Figure 17 Suppose the MT-to-MPO adapter 1 is fixed on the opening 31 of the panel 3, and the MT plug 2 is not plugged with the MT port 11 of the MT-to-MPO adapter 1. For example, the panel 3 has a plurality of openings 31, and the adapter assembly has a plurality of adapters, and the plurality of adapters are fixed on the plurality of openings 31. Each adapter assembly is used to plug with an MPO plug.

[0130] The flange 10 of the MT-to-MPO adapter 1 is made of conductive plastic.

[0131] In the optical communication device provided by embodiments of the present application, since the flange is made of conductive plastic, the MT-to-MPO adapter can realize electromagnetic wave shielding with a larger area, and reduce the security risks. Moreover, since the conductive plastic has a certain elasticity, it can reduce the wear of the flange and improve the service life of the flange.

[0132] Figure 18 is a partial structure schematic diagram of an optical communication device provided by embodiments of the present application. As Figure 18 The optical communication device 0 further comprises:

[0133] Two structural members 32, the two structural members are fixed on both sides of the opening 31 of the panel 3 along the length direction y of the opening 31. For example, the structural member can be a metal member, which can be made of aluminum alloy or steel material, etc. The structural member 32 can be riveted with the panel 3.

[0134] Figure 19 is a partial structure schematic diagram of another optical communication device provided by embodiments of the present application. As Figure 19 The two ends of the flange 10 of the MT-to-MPO adapter are fixed with the two structural members 32 respectively, so as to be installed on the opening 31 of the panel 3.

[0135] The MT to MPO adapter is not directly connected to the panel, but rather indirectly connected via a structural component. This component provides a fixed mounting base for the MT to MPO adapter, reduces damage to the panel, strengthens the panel, and prevents panel deformation caused by excessively large openings due to the increased panel strength.

[0136] For example, the optical communication device also includes: screws ( Figure 19 (Not shown). For example... Figure 18 As shown, each structural component 32 has a second fixing hole 321; the flange 10 has a first fixing hole 101 at both ends in the length direction y.

[0137] Both ends of the flange 10 are fixed to the structural member 32 by screws passing through the first fixing hole 101 and the second fixing hole 322, respectively. Optionally, at least one of the first fixing hole 101 and the second fixing hole 321 is a threaded hole with internal threads, and the screw has external threads, thus achieving an effective connection between the screw and the threaded hole, thereby achieving effective fixation between the flange 10 and the structural member 32. For example, the first fixing hole 101 is a non-threaded hole, and the second fixing hole 321 is a threaded hole.

[0138] In one alternative embodiment, the structural member 32 includes a strip-shaped reinforcing rib. The strip-shaped reinforcing rib strengthens the panel and extends its service life. The extending direction of the strip-shaped reinforcing rib is parallel to the width direction of the opening 31. In a first alternative example, the strip-shaped reinforcing rib is wider, for example, its width is a first width, allowing for the provision of the second fixing hole 321. In a second alternative embodiment, the strip-shaped reinforcing rib is narrower, for example, its width is a second width, which is smaller than the first width. The structural member 32 also includes a block-shaped reinforcing rib located at one end of the strip-shaped reinforcing rib (e.g., Figure 18 The block-shaped reinforcing rib is located at the upper end of the strip-shaped reinforcing rib and is fixedly connected to the strip-shaped reinforcing rib. This block-shaped reinforcing rib is used to provide the aforementioned second fixing hole 321. Compared to the first example described above, the area of ​​the structural component in the second example is reduced, resulting in less material usage and cost savings.

[0139] like Figure 18 As shown, the panel 3 has positioning holes 322. Correspondingly, as... Figure 3As shown, the flange has a guide pin 102 configured to insert into a positioning hole 322 on the panel 3. For example, the guide pin 102 is located on the side where the MPO port 12 of the flange 10 is located. When the MT to MPO adapter is installed on the panel, the MPO port 12 of the MT to MPO adapter is inserted into the opening from one side, and the guide pin 102 is inserted into the positioning hole 322 on the panel 3, after which the MPO port 12 is exposed from the other side of the opening. The guide pin and positioning hole prevent the MT to MPO adapter from being installed in reverse, ensuring a stable and accurate connection between the MT to MPO adapter and the opening.

[0140] Figure 20 This is an exploded view of an optical communication device 0 provided in an embodiment of this application. Figure 20 As shown, the optical communication device 0 also includes a shielding gasket 4, which is capable of shielding electromagnetic waves. The shielding gasket 4 is located between the MT to MPO adapter 1 and the panel 3. By setting the shielding gasket, effective sealing and reliable contact between the MT to MPO adapter and the panel can be achieved, better preventing electromagnetic leakage. The adapter assembly may include the shielding gasket 4.

[0141] For example, the shielding gasket 4 is a flexible conductive gasket. Because the flexible conductive gasket has a certain degree of elasticity, it can reduce wear between the MT to MPO adapter 1 and the panel 3, thus improving their service life.

[0142] In summary, in the optical communication equipment provided in this application embodiment, because the flange is made of conductive plastic, the MT to MPO adapter can achieve electromagnetic wave shielding over a larger area, reducing safety hazards. Furthermore, because the conductive plastic has a certain degree of elasticity, it can reduce flange wear and extend the flange's service life.

[0143] Furthermore, when all the MT ports of the MT-to-MPO adapter are connected to an MT clip with an opening area of ​​3.25*1.95 square millimeters, each adapter assembly can achieve at least 10dB of shielding capability against electromagnetic waves in the frequency range of 0 to 35 GHz. Thus, even if multiple adapter assemblies are installed on a single panel, electromagnetic wave shielding can be effectively achieved. Therefore, the optical communication device provided in this application supports the installation of multiple adapter assemblies, thereby enabling multi-fiber output from the panel and achieving high bandwidth. For example, a single board can provide 4 to 8 MPO ports (i.e., 4 to 8 adapter assemblies are installed).

[0144] This application also provides an optical communication system, which includes one or more of the aforementioned optical communication devices, such as routers or switches, which are high-speed, high-frequency single boards.

[0145] In the drawings of the foregoing embodiments, the MT-to-MPO adapter 1 is taken as an example, and there is one MT-to-MPO adapter 1 and one MT plug 2 used for plugging with the MT-to-MPO adapter 1. In actual implementation, there can be multiple MT-to-MPO adapters 1, and there can be multiple MT plugs 2 used for plugging with each MT-to-MPO adapter 1, and the embodiments of the present application will not be repeated here.

[0146] In the present application, the term "and / or" is only used to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0147] In the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. The term "multiple" refers to two or more, unless otherwise explicitly limited. "A refers to B" means that A is the same as B, or A is a simple transformation based on B.

[0148] The above is only an optional embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
