Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a switching device. Background Art

[0002] After manufacturing, Smart NICs need to be tested using optical modules. During testing, the optical module's gold finger is inserted into the Smart NIC's optical cage. After the test is complete, the module is removed from the cage. Because a large number of Smart NICs need to be tested, frequent insertion and removal of optical modules can wear out the module's gold finger, leading to malfunctions.

[0003] In the related art, an adapter card is connected to the gold finger end of the optical module to reduce wear on the gold finger of the optical module. When testing the smart network card, the gold finger of the adapter card is inserted into the optical cage of the smart network card to test the smart network card. After the test is completed, the adapter card only needs to be removed from the smart network card. The adapter card can protect the gold finger of the optical module, reduce wear on the gold finger of the optical module, and thus reduce the loss of the optical module. However, the adapter card in the related art has the problem of low transmission rate. Summary of the Invention

[0004] The present application provides an adapter device to at least solve the problem of low transmission rate of the adapter card in the related art.

[0005] The present application provides a switching device, comprising:

[0006] The main frame has an input interface and an output interface arranged relative to each other; the input interface is used to be inserted into the electrical interface of the optical module; the output interface is used to be inserted into the optical cage of the device to be tested and docked with the connector of the device to be tested; the output interface is constructed so that when the input interface is inserted into the electrical interface, the top surface of the output interface is not higher than the top surface of the electrical interface, and the bottom surface of the output interface is not higher than the bottom surface of the electrical interface; the length of the output interface is configured to be smaller than the length of the optical cage;

[0007] The transmission conductor is arranged in the main frame; the two ends of the transmission conductor in the extension direction respectively have an input connection end and an output connection end; the input connection end extends into the input interface and is used to be electrically connected to the electrical interface; the output connection end extends into the output interface and is used to be electrically connected to the connector.

[0008] Through this application, the main frame is constructed such that, when the input interface is inserted into the electrical interface of the optical module, the top surface of the output interface is no higher than the top surface of the electrical interface, the bottom surface of the output interface is no lower than the bottom surface of the electrical interface, and the lengthwise dimension between the two ends of the output interface is configured to be less than the length of the optical cage. When the optical module and adapter are inserted into the optical cage of the device under test, not only the output interface but also the electrical interface of the optical module is inserted into the optical cage of the device under test. Compared to adapter cards in related technologies, the length of the adapter is reduced, thereby shortening the length of the signal integrity link of the adapter and improving the transmission rate of the adapter.

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] It should be noted that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for ease of description and simplification of the present application. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°. "Equal" includes both absolute equality and approximate equality, where the acceptable deviation range for approximate equality may be, for example, that the difference between the two is less than or equal to 5% of either. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0044] As described in the background technology, the adapter card in the related art has the problem of low transmission rate. The inventors have found that the reason for this problem is that after the adapter card in the related art is connected to the optical module, the top and bottom surfaces of the adapter card are inconsistent in height with the top and bottom surfaces of the optical module. The adapter card and the optical module cannot be inserted into the optical cage of the smart network card at the same time. Therefore, the length of the adapter card needs to be consistent with the length of the optical cage of the smart network card to meet the insertion stroke requirement, resulting in the signal integrity link of the adapter card being too long, thereby reducing the transmission rate of the adapter card.

[0045] To address the above technical issues, an embodiment of the present application provides an adapter device that transmits data via a transmission conductor and connects an optical module to a device under test via a main frame. The main frame has an input interface and an output interface. The input interface is configured to be inserted into the electrical interface of the optical module; the output interface is configured to be inserted into the optical cage of the device under test and dock with the connector of the device under test. When the input interface is inserted into the electrical interface of the optical module, the top surface of the output interface is no higher than the top surface of the electrical interface, the bottom surface of the output interface is no lower than the bottom surface of the electrical interface, and the length between the two ends of the output interface is configured to be less than the length of the optical cage. When the optical module and adapter device are inserted into the optical cage of the device under test, not only the output interface is inserted into the optical cage of the device under test, but also the electrical interface portion of the optical module is inserted into the optical cage of the device under test. Compared to adapter cards in related technologies, the length of the adapter device is reduced, thereby shortening the length of the signal integrity link of the adapter device and improving the transmission rate of the adapter device.

[0046] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] refer to Figure 1 It should be noted that the adapter 10 of the embodiment of the present application is applied to the optical module 800 and the device to be tested.

[0048] The following references Figure 1 The structure of the optical module 800 is described.

[0049] The optical module 800 includes an optical interface and an electrical interface 810 that are arranged opposite to each other.

[0050] The optical interface is a physical port of the optical module 800 used to transmit or receive optical signals and is used to connect to an external optical fiber link (such as an optical fiber jumper or optical cable) to implement input / output of optical signals.

[0051] Electrical interface 810 is the physical interface for transmitting electrical signals between optical module 800 and external devices (such as switches, routers, smart network cards, server motherboards, etc.). It is responsible for sending the electrical signals output by external devices into optical module 800 for optical-to-electrical conversion, or receiving the electrical signals output by optical module 800 after completing the electrical-to-optical conversion.

[0052] The electrical interface 810 has a gold finger 820 , which is used to achieve electrical connection with an external device.

[0053] The device to be tested may be a smart network card, a switch, a router, a server mainboard, or other device that can interact with the optical module 800 .

[0054] The device under test (DUT) includes an optical cage and a connector. The optical cage is used to mount and secure the electrical interface 810 of the optical module 800. The connector is located within the optical cage and interfaces with the electrical interface 810 of the optical module 800. The connector has gold fingers that electrically connect the DUT to the optical module 800.

[0055] When the electrical interface 810 of the optical module 800 is inserted into the optical cage, the gold fingers 820 at the electrical interface 810 are electrically connected to the gold fingers at the connector to perform data transmission.

[0056] refer to Figure 1 The adapter device 10 provided in an embodiment of the present application includes a main frame 100 and a transmission conductor 200.

[0057] refer to Figure 2 The main frame 100 has an input interface 110 and an output interface 120 that are arranged opposite to each other. The input interface 110 and the output interface 120 are sequentially arranged along the length direction X of the main frame 100 and are adjacent to each other.

[0058] The input interface 110 is configured to be plugged into the electrical interface 810 of the optical module 800 .

[0059] The output interface 120 is used to be inserted into the optical cage of the device to be tested and to connect with the connector of the device to be tested.

[0060] refer to Figure 3 and Figure 4 When the input interface 110 is inserted into the electrical interface 810 , the portion of the main frame 100 located in front of the electrical interface 810 is the output interface 120 .

[0061] It should be noted that the directional word "front" in the embodiment of the present application, that is, Figure 4 The positive direction of X.

[0062] refer to Figure 1 , the transmission conductor 200 is arranged in the main frame 100 .

[0063] refer to Figure 5 The transmission conductor 200 has an input connection end 201 and an output connection end 202 at both ends of the extension direction. The input connection end 201 extends into the input interface 110 and is used to electrically connect to the gold finger 820 at the electrical interface 810 when the input interface 110 is inserted into the electrical interface 810.

[0064] The output connection end 202 extends into the output interface 120 . The output connection end 202 is used to electrically connect to the gold finger of the connector when the output interface 120 is docked with the connector.

[0065] The input connection end 201 is electrically connected to the output connection end 202. When the input interface 110 of the adapter 10 is inserted into the electrical interface 810 and the output interface 120 is connected to the connector, the gold finger 820 at the electrical interface 810 is electrically connected to the gold finger at the connector through the transmission conductor 200 to achieve data transmission between the optical module 800 and the device under test.

[0066] refer to Figure 4 The main frame 100 is constructed so that when the input interface 110 is inserted into the electrical interface 810, the top surface 121 of the output interface is not higher than the top surface 811 of the electrical interface, and the bottom surface 122 of the output interface is not higher than the bottom surface 812 of the electrical interface; the dimension between the two ends of the output interface 120 in the length direction X is constructed to be smaller than the length of the light cage.

[0067] The two end surfaces of the output interface 120 in the width direction Y are respectively used to be flush with the two sides of the electrical interface 810, so that when the input interface 110 is inserted into the electrical interface 810, the two end surfaces of the output interface 120 in the width direction are respectively flush with the two end surfaces of the electrical interface 810.

[0068] When the input interface 110 is inserted into the electrical interface 810, the top surface 121 of the output interface is not higher than the top surface 811 of the electrical interface. That is, along the height direction Z of the main frame 100, the height of the top surface 121 of the output interface is below the height of the top surface 811 of the electrical interface. The top surface 121 of the output interface can be flush with the top surface 811 of the electrical interface (refer to Figure 4 ), or the top surface 121 of the output interface may be lower than the top surface 811 of the electrical interface.

[0069] When the input interface 110 is inserted into the electrical interface 810, the bottom surface 122 of the output interface is not higher than the bottom surface 812 of the electrical interface. That is, along the height direction Z of the main frame 100, the bottom surface 122 of the output interface is located above the height of the bottom surface 812 of the electrical interface. The bottom surface 122 of the output interface can be flush with the bottom surface 812 of the electrical interface (refer to Figure 4 ), or the bottom surface 122 of the output interface may be higher than the bottom surface 812 of the electrical interface.

[0070] refer to Figure 2 The dimension D1 between the two ends of the output interface 120 in the length direction X is configured to be smaller than the length of the optical cage. After the input interface 110 of the adapter 10 is plugged into the electrical interface 810 of the optical module 800, the optical module 800 and the adapter 10 form a whole (refer to Figure 3 and Figure 4), when the output interface 120 of the adapter device 10 is inserted into the optical cage of the device under test, because the dimension D1 between the two ends of the output interface 120 in the length direction X is configured to be smaller than the length of the optical cage, not only the output interface 120 is inserted into the optical cage of the device under test, but also the electrical interface 810 of the optical module 800 is inserted into the optical cage of the device under test, enabling the adapter device 10 to transmit data between the optical module 800 and the device under test. Compared to the adapter card in the related art, the adapter device 10 of the present embodiment reduces the length of the adapter device 10, thereby shortening the length of the signal integrity link of the adapter device 10, reducing signal attenuation, and improving the transmission rate of the adapter device 10.

[0071] In some possible implementations of the present application, reference is made to Figure 6 and Figure 7 The transmission conductor 200 may include an upper conductor 300 and a lower conductor 400 spaced apart along the height direction Z of the main frame 100 , and the upper conductor 300 is located above the lower conductor 400 .

[0072] refer to Figure 6 The upper conductor 300 and the lower conductor 400 each include a plurality of conductor members 203 arranged at intervals along the width direction Y of the main frame 100 .

[0073] For example, refer to Figure 7 The upper conductor 300 may include a plurality of upper conductor members 2031 , and the plurality of upper conductor members 2031 are arranged at intervals along the width direction Y of the main frame 100 .

[0074] refer to Figure 7 The lower conductor 400 may include a plurality of lower conductor members 2032 , and the plurality of lower conductor members 2032 are arranged at intervals along the width direction Y of the main frame 100 .

[0075] The plurality of upper conductive elements 2031 and the plurality of lower conductive elements 2032 are arranged in a staggered manner along the width direction Y of the main frame 100 .

[0076] The upper conductor 300 and the lower conductor 400 located in the output interface 120 constitute the output connection end 202 . When the output interface 120 is connected to the connector, the output connection end 202 is electrically connected to the gold finger of the connector.

[0077] The upper conductor 300 and the lower conductor 400 located within the input interface 110 constitute the input connection end 201, which is used to clamp the gold finger 820 at the electrical interface 810. When the input interface 110 is inserted into the electrical interface 810, the upper conductor 300 abuts the top of the gold finger 820 at the electrical interface 810, and the lower conductor 400 abuts the bottom of the gold finger 820 at the electrical interface 810, so that the input connection end 201 clamps the gold finger 820 at the electrical interface 810, thereby electrically connecting to the gold finger 820 at the electrical interface 810.

[0078] The input connection end 201 is electrically connected to the electrical interface 810 by clamping the gold finger 820 at the electrical interface 810, so that the gold finger 820 at the electrical interface 810 is not easily separated from the input connection end 201, thereby improving the stability of signal transmission between the optical module 800 and the adapter 10.

[0079] In some possible implementations of the present application, reference is made to Figure 6 The conductor part 203 in the upper conductor 300, that is, the upper conductor part 2031, can include a first upper connecting segment 301, a second upper connecting segment 302 and a third upper connecting segment 303 located in the input interface 110. The end of the first upper connecting segment 301 facing away from the output interface 120 is bent downward to form the second upper connecting segment 302, and the end of the second upper connecting segment 302 facing away from the first upper connecting segment 301 is bent upward to form the third upper connecting segment 303.

[0080] refer to Figure 6 The conductor part 203 in the lower conductor 400, that is, the lower conductor part 2032, includes a first lower connecting segment 401, a second lower connecting segment 402 and a third lower connecting segment 403 located in the input interface 110. The end of the first lower connecting segment 401 facing away from the output interface 120 is bent upward to form the second lower connecting segment 402, and the end of the second lower connecting segment 402 facing away from the first lower connecting segment 401 is bent downward to form the third lower connecting segment 403.

[0081] The second upper connecting section 302 and the second lower connecting section 402 are used to clamp the gold finger 820 at the electrical interface 810. Along the height direction Z, the minimum distance between the second upper connecting section 302 and the second lower connecting section 402 is less than the thickness of the gold finger 820 at the electrical interface 810. This allows the second upper connecting section 302 and the second lower connecting section 402 to clamp the gold finger 820 at the electrical interface 810, thereby improving the reliability of the electrical connection between the input connection terminal 201 and the gold finger 820 at the electrical interface 810.

[0082] The distance between the end of the second upper connecting section 302 away from the first upper connecting section 301 and the rear end of the main frame 100 can be equal to the distance between the end of the second lower connecting section 402 away from the first lower connecting section 401 and the rear end of the main frame 100, so that the end of the second upper connecting section 302 away from the first upper connecting section 301 can be opposite to the end of the second lower connecting section 402 away from the first lower connecting section 401, thereby improving the reliability of the input connection terminal 201 clamping the gold finger 820 at the electrical interface 810.

[0083] Along the direction from the input interface 110 to the output interface 120, the distance between the third upper connecting section 303 and the third lower connecting section 403 along the height direction Z gradually decreases to guide the gold finger 820 at the electrical interface 810, thereby avoiding the gold finger 820 at the electrical interface 810 from docking and offsetting with the input connection end 201, and reducing the friction resistance during the plugging and unplugging process, making docking more labor-saving.

[0084] In some possible implementations of the present invention, the conductor 203 can be formed by stamping an alloy plate of a certain thickness into a strip shape and then plating the surface with gold. Gold has high conductivity and can efficiently transmit high-frequency signals and high currents, reducing energy loss during signal transmission, thereby improving the transmission performance of the transmission conductor 200.

[0085] The thickness of the conductor 203 may be 30 micrometers to 300 micrometers. For example, the thickness of the conductor 203 may be 30 micrometers, 200 micrometers, or 300 micrometers.

[0086] When the thickness of the conductor 203 is less than 30 micrometers, the conductor 203 is too thin, resulting in reduced wear resistance of the conductor 203 and reduced transmission performance of the conductor 203 .

[0087] When the thickness of the conductor 203 is greater than 300 microns, the thickness of the conductor 203 is too large, and the distance between the bottom surface of the upper conductor 300 and the top surface of the lower conductor 400 will be reduced, resulting in mutual interference between the signals of the upper conductor 300 and the lower conductor 400.

[0088] When the thickness of the conductor part 203 is between 30 microns and 300 microns, it can not only improve the wear resistance of the conductor part 203 and increase the service life of the transmission conductor 200, but also improve the transmission performance of the conductor part 203 and avoid mutual interference between the signals of the upper conductor 300 and the lower conductor 400.

[0089] In some possible implementations of the embodiment of the present application, the conductor 203 includes a first connecting segment, a second connecting segment, and an intermediate connecting segment.

[0090] The first connection section is used to electrically connect to the gold finger at the electrical interface 810 .

[0091] The second connecting section is used to electrically connect to the gold finger at the connector.

[0092] The middle connecting segment is connected between the first connecting segment and the second connecting segment, and a width of at least a portion of the middle connecting segment is 250 micrometers to 630 micrometers.

[0093] When the width of the intermediate connecting section is less than 250 micrometers, the strength of the intermediate connecting section will be reduced.

[0094] When the width of the middle connecting section is greater than 630 micrometers, the distance between two adjacent conductor members 203 along the width direction Y is too small or even close to each other, which reduces the transmission performance of the conductor members 203 .

[0095] When the width of at least part of the middle connecting section is 250 μm to 630 μm, the structural strength of the middle connecting section and the entire conductor 203 can be increased, and interference between two adjacent conductors 203 can be avoided.

[0096] In some possible implementations of the embodiment of the present application, the width of the main frame 100 may be 18.35 mm and the height may be 8.5 mm.

[0097] It should be noted that, in the description of the embodiments of the present application, length refers to the dimension along the length direction X, height refers to the dimension along the height direction Z, and width refers to the dimension along the width direction Y.

[0098] In some possible implementations of the embodiment of the present application, the length of the main frame 100 may be greater than 15.7 mm.

[0099] In some other possible implementations of the embodiment of the present application, the length of the main frame 100 may be greater than 15.7 mm and not greater than 18.5 mm.

[0100] In some other possible implementations of the embodiment of the present application, a dimension H1 between the two ends of the output interface 120 in the height direction Z may be no greater than 8.5 mm.

[0101] A dimension D1 between two ends of the output interface 120 in the length direction X may be greater than 7.85 mm and not greater than 10.65 mm.

[0102] A dimension H2 between two ends of the input interface 110 in the height direction Z may be 5.65 mm.

[0103] A dimension D2 between two ends of the input interface 110 in the length direction X may be 7.85 mm.

[0104] In some possible implementations of the present application, reference is made to Figure 8The input interface 110 may be configured with a slot 111 , and the slot 111 is used for inserting the gold finger 820 at the power supply interface 810 .

[0105] In some possible implementations of the present application, reference is made to Figure 9 and Figure 10 The top of the output interface 120 may have an upper guide plate 124 , and the bottom of the output interface 120 may have a lower guide plate 125 . The upper guide plate 124 and the lower guide plate 125 are arranged opposite to each other, and an insertion space 126 is formed between the upper guide plate 124 and the lower guide plate 125 .

[0106] When the output interface 120 of the adapter 10 is docked with the connector of the device to be tested, the upper guide plate 124 and the lower guide plate 125 are used to guide the interface of the connector to avoid docking deviation.

[0107] refer to Figure 5 , the input connection end 201 of the transmission conductor 200 extends into the slot 111. Figure 10 , the output connection end 202 of the transmission conductor 200 extends into the insertion space 126 .

[0108] In some possible implementations of the present application, reference is made to Figure 10 The main frame 100 may be constructed with a plug-in channel 101 extending along the length direction X, and the plug-in channel 101 connects the input interface 110 and the output interface 120 , that is, the plug-in channel 101 connects the slot 111 and the insertion space 126 .

[0109] The transmission conductor 200 can be inserted into the main frame 100 through the insertion channel 101 .

[0110] refer to Figure 6 The transmission conductor 200 may include a rubber core 500 , and the rubber core 500 may be made of polydecanediamine sebacate to improve the wear resistance, formability and saturation modulus of the rubber core 500 .

[0111] refer to Figure 12 and Figure 13 The rubber core 500 may be configured with a plurality of upper slots 511 and a plurality of lower slots 513 .

[0112] The plurality of upper card slots 511 are arranged at intervals along the width direction Y. The slot openings of the upper card slots 511 face upward. The plurality of lower card slots 513 are arranged at intervals along the width direction Y. The slot openings of the lower card slots 513 face downward.

[0113] refer to Figure 14 The plurality of conductors 203 in the upper conductor 300 are respectively locked in the plurality of upper locking grooves 511 . The plurality of conductors 203 in the lower conductor 400 are respectively locked in the plurality of lower locking grooves 513 .

[0114] The rubber core 500 fixes the conductor parts 203 in the upper conductor 300 and the lower conductor 400 respectively. The multiple conductor parts 203 in the upper conductor 300 and the multiple conductor parts 203 in the lower conductor 400 are first assembled on the rubber core 500, and then the transmission conductor 200 composed of the upper conductor 300, the lower conductor 400 and the rubber core 500 is inserted into the insertion channel 101, which reduces the difficulty of assembling the upper conductor 300, the lower conductor 400 and the main frame 100 and improves the assembly efficiency of the adapter 10.

[0115] In some possible implementations of the embodiment of the present application, the upper slot 511 has an upper stop sidewall on a side facing away from the input connection end 201 , and the distance between the upper stop sidewall and the input connection end 201 decreases from bottom to top.

[0116] refer to Figure 7 The end of the conductor part 203 in the upper conductor 300 is constructed with an upper chamfer 304, which cooperates with the upper stop side wall to stop the conductor part 203. The upper stop side wall can stop at the top of the upper chamfer 304, so that the conductor part 203 in the upper conductor 300 is not easy to fall out of the slot of the upper slot 511, thereby improving the reliability of the assembly of the conductor part 203 and the rubber core 500, and avoiding the occurrence of phenomena such as the conductor part 203 falling off and curling after too many plugging and unplugging times.

[0117] refer to Figure 15 and Figure 16 The lower slot 513 has a lower stop side wall 514 on a side facing away from the input connection end 201 , and the distance between the lower stop side wall 514 and the input connection end 201 decreases from top to bottom.

[0118] refer to Figure 7 , the end of the conductor piece 203 in the lower conductor 400 is configured with a lower chamfer 404. Figure 16 The lower chamfer 404 cooperates with the lower stop side wall 514 to stop the lower stop side wall 514. The lower stop side wall 514 can stop at the bottom of the lower chamfer 404, so that the conductor part 203 in the lower conductor 400 is not easy to fall out from the slot of the lower card slot 513, thereby improving the reliability of the assembly of the conductor part 203 and the rubber core 500, and avoiding the phenomenon of the conductor part 203 falling off and curling after too many plugging and unplugging times.

[0119] In some possible implementations of the present application, reference is made to Figure 12 and Figure 13 The rubber core 500 may further be configured with a second slot 515, which is located between the upper slot 511 and the lower slot 513. The notch of the second slot 515 may be located at one end of the length direction X of the rubber core 500.

[0120] refer to Figure 17The transmission conductor 200 may further include a shielding sheet 600, which is in sheet shape. Figure 14 The shielding sheet 600 is inserted into the second card slot 515 through the slot of the second card slot 515. The shielding sheet 600 is located between the upper conductor 300 and the lower conductor 400. The shielding sheet 600 is used to isolate the mutual interference generated by the upper conductor 300 and the lower conductor 400 during high-speed signal transmission, making the signal transmission more stable.

[0121] In some possible implementations of the present application, reference is made to Figure 16 The second slot 515 may include a first slot section 5151 and a second slot section 5152 arranged along the length direction X of the main frame 100 .

[0122] The first slot section 5151 is closer to the input connection end 201 than the second slot section 5152 . An end of the first slot section 5151 away from the second slot section 5152 penetrates the rubber core 500 and forms a notch of the second slot 515 .

[0123] The second slot section 5152 is connected to the first slot section 5151 ; along the height direction Z, the size of the second slot section 5152 is smaller than that of the first slot section 5151 .

[0124] refer to Figure 17 The shielding sheet 600 may include a first portion 610 and a second portion 620 connected to each other. The first portion 610 is inserted into the first slot section 5151 , and the second portion 620 is fixedly inserted into the second slot section 5152 .

[0125] It should be noted that “fixed insertion” means that after the second part 620 is inserted into the second slot section 5152 , a fixed connection is achieved between the second part 620 and the second slot section 5152 , and the second part 620 is tightly clamped in the second slot section 5152 .

[0126] The shielding sheet 600 is clamped and fixed to the rubber core 500 through the second clamping groove 515 , which simplifies the assembly process of the shielding sheet 600 and the rubber core 500 and improves the assembly efficiency of the shielding sheet 600 and the rubber core 500 .

[0127] In some possible implementations of the present application, reference is made to Figure 6 , the rubber core 500 may include a core plate 510, an upper pressing plate 520 and a lower pressing plate 530;

[0128] refer to Figure 12 and Figure 13The upper surface of the core plate 510 may be configured with upper retaining grooves 511, and the lower surface of the core plate 510 may be configured with lower retaining grooves 513. The plurality of conductors 203 in the upper conductor 300 are respectively retained in the plurality of upper retaining grooves 511. The plurality of conductors 203 in the lower conductor 400 are respectively retained in the plurality of lower retaining grooves 513.

[0129] After the plurality of conductors 203 in the upper conductor 300 are respectively clamped in the plurality of upper clamping grooves 511, and the plurality of conductors 203 in the lower conductor 400 are respectively clamped in the plurality of lower clamping grooves 513, the upper conductor 300, the lower conductor 400 and the core plate 510 form a whole (refer to FIG. Figure 14 and Figure 17 ). refer to Figure 6 and Figure 17 The upper pressing plate 520 and the lower pressing plate 530 are respectively pressed onto the top and bottom of the whole to form the transmission conductor 200.

[0130] The upper pressing plate 520 is pressed onto the top of the core plate 510 and the portion of the upper conductor 300 close to the input port 110 .

[0131] The lower pressing plate 530 is pressed onto the bottom of the core plate 510 and the portion of the lower conductor 400 close to the input port 110 .

[0132] The transmission conductor 200, which is composed of a core plate 510, an upper conductor 300, a lower conductor 400, an upper pressing plate 520, and a lower pressing plate 530, is assembled by first assembling the upper conductor 300 and the lower conductor 400 to the core plate 510. Then, the upper pressing plate 520 and the lower pressing plate 530 are pressed onto the top and bottom of the core plate 510 assembled with the upper conductor 300 and the lower conductor 400, respectively, to form the transmission conductor 200. This simplifies the assembly process of the upper conductor 300, the lower conductor 400, and the rubber core 500, and improves the assembly efficiency of the upper conductor 300, the lower conductor 400, and the rubber core 500.

[0133] Finally, the transmission conductor 200 composed of the core board 510, the upper conductor 300, the lower conductor 400, the upper pressure plate 520 and the lower pressure plate 530 is pressed into the plug-in channel 101, thereby completing the assembly between the transmission conductor 200 and the main frame 100, simplifying the assembly procedure of the adapter device 10 and improving the assembly efficiency of the adapter device 10.

[0134] In some possible implementations of the present application, reference is made to Figure 17 The adapter device 10 may further include a fixing buckle 700, which is used to engage with the positioning hole on the electrical interface 810 when the input interface 110 is docked with the electrical interface 810, so that the adapter device 10 is fixedly connected to the electrical interface 810, making it difficult for the adapter device 10 to detach from the electrical interface 810.

[0135] refer to Figure 17 The fixing buckle 700 may include an elastic connecting portion 710 , a locking hook 720 , a supporting portion 730 and an unlocking portion 740 .

[0136] refer to Figure 8 The elastic connection portion 710 may extend substantially along the longitudinal direction X of the main frame 100. The elastic connection portion 710 may be in the shape of an elongated plate or a long rod. The elastic connection portion 710 has a certain degree of elasticity, that is, the elastic connection portion 710 may bend to a certain extent under the action of an external force.

[0137] The elastic connection portion 710 may be embedded in the top of the input interface 110 , and a portion of the elastic connection portion 710 close to the output interface 120 is suspended in the air.

[0138] The locking hook 720 can be block-shaped, and the locking hook 720 is set at the top of the elastic connecting part 710, and the top of the locking hook 720 extends above the top surface 112 of the input interface; the locking hook 720 is used to: when the input interface 110 is docked with the electrical interface 810, it is clamped in the positioning hole 830 of the electrical interface.

[0139] The top of the support portion 730 is connected to the end of the elastic connection portion 710 facing away from the output interface 120 , and the support portion 730 is locked in the main frame 100 .

[0140] refer to Figure 10 and Figure 16 The top of the main frame 100 may be configured with a first slot 103 with the slot facing upwards, referring to Figure 16 The support portion 730 can be fixedly inserted into the first card slot 103 , that is, the support portion 730 is clamped in the first card slot 103 so that the support portion 730 is not easily dislodged from the first card slot 103 .

[0141] The bottom of the unlocking portion 740 is connected to the end of the elastic connecting portion 710 facing away from the supporting portion 730, and at least a portion of the unlocking portion 740 is located in front of the input interface 110, so that after the input interface 110 is docked with the electrical interface 810, the unlocking portion 740 will not be inserted into the electrical interface 810, but will be located in front of the electrical interface 810 to facilitate pressing the unlocking portion 740.

[0142] refer to Figure 16 and Figure 17 The top of the output interface 120 is configured with an avoidance notch 123 , the unlocking portion 740 is accommodated in the avoidance notch 123 , and the top of the unlocking portion 740 is not higher than the top surface 121 of the output interface 120 .

[0143] When the input interface 110 needs to be inserted into the electrical interface 810, it is only necessary to connect the input interface 110 and the electrical interface 810 until the locking hook 720 is locked in the positioning hole 830 of the electrical interface (refer to Figure 3 and Figure 16 ), the input interface 110 and the electrical interface 810 are connected. And because the locking hook 720 is locked in the positioning hole 830 of the electrical interface, the input interface 110 is not easily removed from the electrical interface 810.

[0144] When the input interface 110 needs to be removed from the electrical interface 810, simply press the unlocking portion 740 downward. The unlocking portion 740 drives the elastic connecting portion 710 to move downward away from one end of the supporting portion 730, and moves the top end of the locking hook 720 below the top surface 112 of the input interface. At this time, the input interface 110 can be removed from the electrical interface 810.

[0145] In some possible implementations of the present application, reference is made to Figure 16 and Figure 17 The main frame 100 may be configured with a first limiting step 102 , which is located in the avoidance gap 123 and below at least a portion of the unlocking portion 740 .

[0146] When the unlocking portion 740 is pressed until it abuts against the first limiting step 102, the top of the locking hook 720 moves below the top of the input interface 110. At this time, the locking hook 720 and the positioning hole 830 of the electrical interface are released from the stop. By pressing the unlocking portion 740 and moving the input interface 110 outward at the same time, the adapter 10 can be separated from the electrical interface 810.

[0147] The first limiting step 102 can prevent the unlocking portion 740 from moving downward excessively when unlocking, causing the elastic connecting portion 710 to bend too much and exceed the elastic limit and be unable to rebound, thereby increasing the service life of the fixing buckle 700.

[0148] In some possible implementations of the present application, reference is made to Figure 10 and Figure 16 The main frame 100 may also be configured with an escape step 104. The escape step 104 is located below the portion of the elastic connection portion 710 that is adjacent to the output interface 120. The distance between the escape step 104 and the top surface 112 of the input interface increases as it approaches the output interface 120. When the elastic connection portion 710 bends downward along with the unlocking portion 740, the space above the escape step 104 provides space for the elastic deformation of the elastic connection portion 710. This allows the elastic connection portion 710 to deform elastically, thereby driving the locking hook 720 to move downward and out of the positioning hole 830 of the electrical interface.

[0149] In some possible implementations of the present application, reference is made to Figure 9 、 Figure 10 and Figure 16 The main frame 100 may be configured with a second limiting step 105, which stops at the end of the rubber core 500 facing away from the output interface 120. When the transmission conductor 200, consisting of the upper conductor 300, the lower conductor 400, and the rubber core 500, is inserted from front to back into the insertion channel 101, the second limiting step 105 is used to stop at the end of the rubber core 500 facing away from the output interface 120, thereby limiting the insertion position of the rubber core 500 and improving the accuracy of the assembly of the transmission conductor 200 and the main frame 100.

[0150] It should be noted that, in the embodiment of the present application, “forward” refers to the direction from the input interface 110 to the output interface 120 along the length direction X. “Backward” refers to the direction from the output interface 120 to the input interface 110 along the length direction X.

[0151] In some possible implementations of the present application, reference is made to Figure 9 、 Figure 10 and Figure 16 The main frame 100 can be constructed with multiple upper limit slots 106 and multiple lower limit slots 107.

[0152] The plurality of upper limit slots 106 may be located above the slot 111 , and the plurality of lower limit slots 107 may be located below the slot 111 . The bottom of the upper limit slot 106 and the side facing the output interface 120 are both in communication with the slot 111 .

[0153] The top of the lower limiting groove 107 and the side facing the output interface 120 are both connected to the slot 111 .

[0154] The plurality of upper limit slots 106 are arranged at intervals along the width direction Y, and the plurality of conductor members 203 in the upper conductor 300 are respectively accommodated in the plurality of upper limit slots 106. The conductor members 203 in the upper conductor 300 can be inserted into the upper limit slots 106 through the upper limit slots 106 toward the side of the output interface 120 and can move up and down within the upper limit slots 106. The upper limit slots 106 can limit the freedom of the conductor members 203 in the upper conductor 300 along the width direction Y and the height direction Z, thereby preventing the conductor members 203 from shifting.

[0155] The plurality of lower limiting grooves 107 are arranged at intervals along the width direction Y, and the plurality of conductive elements 203 in the lower conductor layer 400 are respectively accommodated in the plurality of lower limiting grooves 107. The conductive elements 203 in the lower conductor layer 400 can be inserted into the lower limiting grooves 107 toward the side of the output interface 120 through the lower limiting grooves 107 and can move up and down within the lower limiting grooves 107. The lower limiting grooves 107 can limit the freedom of the conductive elements 203 in the lower conductor layer 400 along the width direction Y and the height direction Z, thereby preventing the conductive elements 203 from shifting.

[0156] In some possible implementations of the present application, reference is made to Figure 8 and Figure 17 The main frame 100 may also be configured with a third stopper step 108. The third stopper step 108 is located on the side of the output interface 120 facing the input interface 110. The third stopper step 108 is configured to stop the front end 813 of the electrical interface. The third stopper step 108 is configured to limit the insertion distance of the input interface 110 into the electrical interface 810 of the optical module 800, ensuring accurate alignment of the input interface 110 with the electrical interface 810 of the optical module 800.

[0157] In some possible implementations of the present application, reference is made to Figure 8 A guide groove 127 may also be constructed on the top of the output interface 120. The guide groove 127 is used to cooperate with the guide column or boss on the device to be tested, so that the output interface 120 and the connector of the device to be tested are accurately docked, avoiding the output connection end 202 and the gold finger at the connector from being misaligned, thereby improving the reliability of the electrical connection between the output connection end 202 and the gold finger at the connector.

[0158] In some possible implementations of the present application, reference is made to Figure 3 A limiting hole 128 may also be constructed on the top of the output interface 120. The limiting hole 128 is used to position and cooperate with the connector of the device to be tested to improve the reliability of the output interface 120 after docking with the connector.

[0159] In some possible implementations of the present application, reference is made to Figure 5 The bottom of the input interface 110 may be configured with an avoidance groove 113 , the notch of the avoidance groove 113 faces downward, and the side of the avoidance groove 113 away from the output interface 120 passes through the main frame 100 .

[0160] refer to Figure 16 The avoidance groove 113 is used to avoid the guide plate 814 of the electrical interface. When the input interface 110 is inserted into the electrical interface 810, the guide plate 814 of the electrical interface can move from the side of the avoidance groove 113 away from the output interface 120 to the inside of the avoidance groove 113, so that the input interface 110 can be reliably connected to the electrical interface 810.

[0161] In some possible implementations of the embodiments of the present application, the front end of the upper guide plate 124 can be constructed with a chamfer, the front end of the lower guide plate 125 can also be constructed with a chamfer, and the front end chamfer of the output interface 120 is consistent with the chamfer of the front end of the electrical interface 810 of the optical module 800, so as to improve the smoothness of the docking between the output interface 120 and the connector of the device to be tested.

[0162] The present application also provides a method for processing the adapter 10, which includes the following steps:

[0163] S110, manufacture the main frame 100 (refer to Figure 9 ), the main frame 100 has an input interface 110 and an output interface 120 arranged opposite each other. The input interface 110 is inserted into the electrical interface 810 of the optical module 800. The output interface 120 is inserted into the optical cage of the device under test and docks with the connector of the device under test. The main frame 100 is constructed so that when the input interface 110 is inserted into the electrical interface 810, the top surface 121 of the output interface is no higher than the top surface 811 of the electrical interface, and the bottom surface 122 of the output interface is no lower than the bottom surface 812 of the electrical interface. The dimension between the ends of the output interface 120 in the longitudinal direction X is configured to be smaller than the length of the optical cage. The main frame 100 is configured with a plug-in channel 101 extending along the longitudinal direction X.

[0164] The main frame 100 can be manufactured by an integral casting method. The material of the main frame 100 can be polyetheretherketone, so that the main frame 100 has the advantages of wear resistance, disassembly resistance and self-lubrication.

[0165] S120, manufacturing transmission conductor 200 (reference Figure 6 ), the transmission conductor 200 has an input connection end 201 and an output connection end 202 at both ends of the extension direction. The input connection end 201 is used to electrically connect to the gold finger 820 at the electrical interface 810. The output connection end 202 is used to electrically connect to the gold finger at the connector.

[0166] S130, press the transmission conductor 200 into the plug-in channel 101, and extend the input connection end 201 into the input interface 110, and the output connection end 202 into the output interface 120 (refer to Figure 11 ).

[0167] The adapter device 10 produced by the processing method of the adapter device 10 of the embodiment of the present application has a top surface 121 of the output interface not higher than the top surface 811 of the electrical interface when the input interface 110 is inserted into the electrical interface 810. That is, along the height direction Z of the main frame 100, the height of the top surface 121 of the output interface is below the height of the top surface 811 of the electrical interface. The top surface 121 of the output interface can be flush with the top surface 811 of the electrical interface, or the top surface 121 of the output interface can be lower than the top surface 811 of the electrical interface.

[0168] When the input interface 110 is inserted into the electrical interface 810, the bottom surface 122 of the output interface is not higher than the bottom surface 812 of the electrical interface. That is, along the height direction Z of the main frame 100, the height of the bottom surface 122 of the output interface is above the height of the bottom surface 812 of the electrical interface. The bottom surface 122 of the output interface can be flush with the bottom surface 812 of the electrical interface, or the bottom surface 122 of the output interface can be higher than the bottom surface 812 of the electrical interface.

[0169] The dimension D1 between the two ends of the output interface 120 in the length direction X is configured to be smaller than the length of the optical cage. After the input interface 110 of the adapter device 10 is inserted into the electrical interface 810 of the optical module 800, the optical module 800 and the adapter device 10 form a single unit. When the output interface 120 of the adapter device 10 is inserted into the optical cage of the device under test, because the dimension D1 between the two ends of the output interface 120 in the length direction X is configured to be smaller than the length of the optical cage, not only the output interface 120 is inserted into the optical cage of the device under test, but also the electrical interface 810 of the optical module 800 is inserted into the optical cage of the device under test, enabling the adapter device 10 to transmit data between the optical module 800 and the device under test. Compared to adapter cards in related art, the adapter device 10 of the present embodiment reduces the length of the adapter device 10, thereby shortening the length of the signal integrity link of the adapter device 10, reducing signal attenuation, and improving the transmission rate of the adapter device 10.

[0170] Wherein, step S120 includes:

[0171] S121, manufacture core board 510 (reference Figure 12 ), the upper surface of the core plate 510 is constructed with multiple upper card slots 511, the lower surface of the core plate 510 is constructed with multiple lower card slots 513, and the side of the core plate 510 is constructed with a second card slot 515.

[0172] The material of the core plate 510 can be polydecanediamine terephthalamide, so that the core plate 510 has the advantages of wear resistance, easy molding, good full modulus, etc. The core plate 510 is cast in one piece.

The conductor part 203 is manufactured by ultra-precision integrated stamping.

[0175] S123, manufacture the upper pressing plate 520 and the lower pressing plate 530 (refer to Figure 17 ).

[0176] The upper pressing plate 520 and the lower pressing plate 530 can both be made of polydecanediamine terephthalamide, so that the upper pressing plate 520 and the lower pressing plate 530 have the advantages of wear resistance, easy forming, good full mold, etc. The upper pressing plate 520 and the lower pressing plate 530 are respectively manufactured by machining.

[0177] S124, manufacturing shielding sheet 600 (reference Figure 17 ).

[0178] The shielding sheet 600 is made of phosphor bronze strip, which has the characteristics of high strength, elasticity, wear resistance and anti-magnetism, etc. The shielding sheet 600 is made by die stamping.

[0179] S125 , press the shielding sheet 600 into the second slot 515 .

[0180] S126, press the plurality of conductor pieces 203 of the upper conductor 300 into the plurality of upper slots 511, and press the plurality of conductor pieces 203 of the lower conductor 400 into the plurality of lower slots 513, to form a first integral body (refer to Figure 14 ).
