A type of adapter

Abstract

This application discloses an adapter, relating to the field of communication technology. The adapter includes a main frame and a transmission conductor. The main frame has an input interface and an output interface. The input interface is used to insert into the electrical interface of an optical module. The output interface is used to insert into the optical cage of a device under test (DUT) and mate with the connector of the DUT. When the input interface is inserted into the electrical interface of the optical module, 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 lower than the bottom surface of the electrical interface. Furthermore, the dimension between the two ends of the output interface in the length direction is configured to be smaller than the length of the optical cage. When the entire assembly of the optical module and the adapter is inserted into the optical cage of the DUT, both the output interface and the electrical interface portion of the optical module are inserted into the optical cage of the DUT, reducing the length of the adapter and thus shortening the signal integrity link length of the adapter, thereby increasing the transmission rate of the adapter.

Description

Technical Field

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

[0002] After manufacturing, smart network interface cards (NICs) need to be tested using optical modules. During testing, the gold fingers of the optical module need to be inserted into the optical cage of the smart NIC. After testing, the optical module is then removed from the cage. Because a large number of smart NICs need to be tested, the optical modules are frequently inserted and removed, causing wear and tear on the gold fingers and potentially leading to malfunctions.

[0003] In related technologies, an adapter card is connected to the gold fingers of the optical module to reduce wear on the gold fingers. When testing a smart network card, the adapter card's gold fingers are inserted into the smart network card's optical cage for testing. After testing, the adapter card can simply be removed from the smart network card. The adapter card protects the gold fingers of the optical module, reducing wear and tear and thus lowering the module's overall loss. However, this type of adapter card suffers from low transmission rates. Summary of the Invention

[0004] This application provides an adapter to at least solve the problem of low transmission rate of adapter cards in related technologies.

[0005] This application provides an adapter, comprising:

[0006] The main frame has an input interface and an output interface that are positioned opposite each other. The input interface is used to insert into the electrical interface of the optical module. The output interface is used to insert into the optical cage of the device under test and mate with the connector of the device under test. The output interface is configured such 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 dimension between the two ends of the output interface in the length direction is configured to be smaller than the length of the optical cage.

[0007] A transmission conductor is disposed within the main frame; the two ends of the transmission conductor extending in the direction of extension have an input connection end and an output connection end respectively; the input connection end extends into the input interface and is used for electrical connection with the electrical interface; the output connection end extends into the output interface and is used for electrical connection with the connector.

[0008] According to 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 not higher than the top surface of the electrical interface, the bottom surface of the output interface is not lower than the bottom surface of the electrical interface, and the dimension between the two ends of the output interface in the length direction is constructed to be smaller than the length of the optical cage. When the entire assembly consisting of the optical module and the adapter is 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 with the adapter card in related technologies, the length of the adapter is reduced, thereby shortening the signal integrity link length of the adapter and improving the transmission rate of the adapter.

Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] As described in the background section, the adapter cards in the related technologies suffer from low transmission rates. The inventors discovered that this problem arises because, after the adapter card is connected to the optical module, the top and bottom surfaces of the adapter card are not at the same height as those of the optical module. As a result, the adapter card and the optical module cannot be inserted into the optical cage of the smart network card simultaneously. Therefore, the length of the adapter card needs to match the length of the optical cage of the smart network card to meet the insertion travel requirements. This results in an excessively long signal integrity link for the adapter card, which reduces the transmission rate of the adapter card.

[0045] To address the aforementioned technical problems, this application provides an adapter device. This adapter device transmits data via a transmission conductor and connects an optical module and a device under test (DUT) via a main frame. The main frame has an input interface and an output interface. The input interface is inserted into the electrical interface of the optical module; the output interface is inserted into the optical cage of the DUT and mates with the connector of the DUT. When the input interface is inserted into the electrical interface of the optical module, 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 lower than the bottom surface of the electrical interface. Furthermore, the dimension between the two ends of the output interface in the length direction is configured to be smaller than the length of the optical cage. When the entire assembly consisting of the optical module and the adapter device is inserted into the optical cage of the DUT, not only the output interface is inserted into the optical cage of the DUT, but also a portion of the electrical interface of the optical module is inserted into the optical cage of the DUT. Compared to adapter cards in related technologies, this reduces the length of the adapter device, thereby shortening the signal integrity link length of the adapter device and improving the transmission rate of the adapter device.

[0046] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] refer to Figure 1 It should be noted that the adapter 10 in this application embodiment is applied to the optical module 800 and the device under test.

[0048] The following is for reference 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 positioned opposite each other.

[0050] The optical interface is the physical port of the optical module 800 used to transmit or receive optical signals. It is used to connect to external fiber optic links (such as fiber optic patch cords or optical cables) to realize the input / output of optical signals.

[0051] The electrical interface 810 is the physical interface for transmitting electrical signals between the 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 the external devices into the optical module 800 for photoelectric conversion, or receiving the electrical signals output by the optical module 800 after completing the electro-optical conversion.

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

[0053] The device to be tested can be a smart network card, switch, router, server motherboard, 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 inside the optical cage and is used to mate with the electrical interface 810 of the optical module 800. The connector has gold fingers, which are used by the DUT to achieve electrical connection with 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 10 provided in this application embodiment 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 arranged sequentially along the length direction X of the main frame 100 and are adjacent to each other.

[0058] The input interface 110 is used to insert into the electrical interface 810 of the optical module 800.

[0059] The output interface 120 is used to insert into the optical cage of the device under test and to mate with the connector of the device under test.

[0060] refer to Figure 3 and Figure 4 When the input interface 110 is inserted into the electrical interface 810, 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 term "front" in the embodiments of this application refers to... Figure 4 The positive direction of X.

[0062] refer to Figure 1 The transmission conductor 200 is disposed within the main frame 100.

[0063] refer to Figure 5 The transmission conductor 200 has an input connection terminal 201 and an output connection terminal 202 at its two ends along its extension direction. The input connection terminal 201 extends into the input interface 110 and is used to electrically connect with 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 202 extends into the output interface 120 and is used to electrically connect with the gold fingers of the connector when the output interface 120 is mated with the connector.

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

[0066] refer to Figure 4 The main frame 100 is configured such 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 configured to be smaller than the length of the optical cage.

[0067] The two ends 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 ends of the output interface 120 in the width direction are respectively flush with the two ends 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, and the top surface 121 of the output interface can be flush with the top surface 811 of the electrical interface (reference). Figure 4 Alternatively, 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 height of the bottom surface 122 of the output interface is above the height of the bottom surface 812 of the electrical interface, and the bottom surface 122 of the output interface can be flush with the bottom surface 812 of the electrical interface (reference). Figure 4 Alternatively, 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 inserted into the electrical interface 810 of the optical module 800, the optical module 800 and the adapter 10 form a whole (see reference). Figure 3 and Figure 4When the output interface 120 of the adapter 10 is inserted into the optical cage of the device under test, since the dimension D1 between the two ends of the output interface 120 in the length direction X is constructed to be smaller than the length of the optical cage, not only is the output interface 120 inserted into the optical cage of the device under test, but also part of the electrical interface 810 of the optical module 800 is inserted into the optical cage of the device under test, enabling the adapter 10 to transmit data between the optical module 800 and the device under test. Compared with the adapter card in the related art, the adapter 10 of this application embodiment reduces the length of the adapter 10, thereby shortening the length of the signal integrity link of the adapter 10, reducing signal attenuation, and improving the transmission rate of the adapter 10.

[0071] In some possible implementations of the embodiments of this 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, with the upper conductor 300 located above the lower conductor 400.

[0072] refer to Figure 6 Both the upper conductor 300 and the lower conductor 400 include multiple conductor elements 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 elements 2031, which 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, which are arranged at intervals along the width direction Y of the main frame 100.

[0075] Multiple upper conductors 2031 and multiple lower conductors 2032 are arranged alternately 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 terminal 202. When the output interface 120 is mated with the connector, the output connection terminal 202 is electrically connected to the gold fingers of the connector.

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

[0078] The input connection terminal 201 achieves electrical connection with the electrical interface 810 by clamping the gold finger 820 at the electrical interface 810, making it difficult for the gold finger 820 at the electrical interface 810 to separate from the input connection terminal 201, thereby improving the stability of signal transmission between the optical module 800 and the adapter 10.

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

[0080] refer to Figure 6 The conductor 203 in the lower conductor 400, also known as the lower conductor 2032, includes a first lower connecting segment 401, a second lower connecting segment 402, and a third lower connecting segment 403 located within 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 fingers 820 at the electrical interface 810. Along the height direction Z, the minimum interval between the second upper connecting section 302 and the second lower connecting section 402 is less than the thickness of the gold fingers 820 at the electrical interface 810, so that the second upper connecting section 302 and the second lower connecting section 402 can clamp the gold fingers 820 at the electrical interface 810, thereby improving the reliability of the electrical connection between the input connection terminal 201 and the gold fingers 820 at the electrical interface 810.

[0082] The distance between the end of the second upper connecting segment 302 away from the first upper connecting segment 301 and the rear end of the main frame 100 can be equal to the distance between the end of the second lower connecting segment 402 away from the first lower connecting segment 401 and the rear end of the main frame 100, so that the end of the second upper connecting segment 302 away from the first upper connecting segment 301 can be opposite to the end of the second lower connecting segment 402 away from the first lower connecting segment 401, thereby improving the reliability of the gold finger 820 clamping at the input connection terminal 201 to 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 segment 303 and the third lower connecting segment 403 gradually decreases along the height direction Z to guide the gold fingers 820 at the electrical interface 810, prevent the gold fingers 820 at the electrical interface 810 from misaligning with the input connection terminal 201, and reduce the frictional resistance during the insertion and removal process, making the connection easier.

[0084] In some possible implementations of this application, the conductor 203 can be made by stamping an alloy plate of a certain thickness into a strip and then plating it with gold. Gold has high conductivity, which can efficiently transmit high-frequency signals and large currents, reduce energy loss of signals during transmission, and thus improve the transmission performance of the transmission conductor 200.

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

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

[0087] When the thickness of conductor 203 is greater than 300 micrometers, the thickness of 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 conductor 203 is between 30 micrometers and 300 micrometers, it can improve the wear resistance of conductor 203, increase the service life of transmission conductor 200, improve the transmission performance of conductor 203, and avoid mutual interference between signals between upper conductor 300 and lower conductor 400.

[0089] In some possible implementations of the embodiments of this 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 for electrical connection with the gold fingers at the electrical interface 810.

[0091] The second connecting section is used for electrical connection with the gold fingers at the connector.

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

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

[0094] When the width of the intermediate connection segment is greater than 630 micrometers, the spacing between two adjacent conductors 203 along the width direction Y is too small or even too close, which reduces the transmission performance of the conductor 203.

[0095] When the width of at least part of the intermediate connecting segment is 250 micrometers to 630 micrometers, it can increase the structural strength of the intermediate connecting segment and the entire conductor 203, and also avoid interference between two adjacent conductors 203.

[0096] In some possible implementations of the embodiments of this application, the width of the main frame 100 can be 18.35 mm and the height can be 8.5 mm.

[0097] It should be noted that in the description of the embodiments of this 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 embodiments of this application, the length of the main frame 100 may be greater than 15.7 mm.

[0099] In some other possible implementations of the embodiments of this 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 this application, the dimension H1 between the two ends of the output interface 120 in the height direction Z may not be greater than 8.5 mm.

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

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

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

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

[0105] In some possible implementations of the embodiments of this 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 mated with the connector of the device under test, the upper guide plate 124 and the lower guide plate 125 are used to guide the interface of the connector to avoid mating misalignment.

[0107] refer to Figure 5 The input connection terminal 201 of the transmission conductor 200 extends into the slot 111. (Reference) Figure 10 The output connection terminal 202 of the transmission conductor 200 extends into the insertion space 126.

[0108] In some possible implementations of the embodiments of this 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. 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 via the insertion channel 101.

[0110] refer to Figure 6 The transmission conductor 200 may include a core 500, which may be made of polydecylidene diamine to improve the wear resistance, formability and moldability of the core 500.

[0111] refer to Figure 12 and Figure 13 The core 500 can be constructed with multiple upper slots 511 and multiple lower slots 513.

[0112] Multiple upper card slots 511 are arranged at intervals along the width direction Y. The openings of the upper card slots 511 face upwards. Multiple lower card slots 513 are arranged at intervals along the width direction Y. The openings of the lower card slots 513 face downwards.

[0113] refer to Figure 14 The multiple conductors 203 in the upper conductor 300 are respectively secured in multiple upper slots 511. The multiple conductors 203 in the lower conductor 400 are respectively secured in multiple lower slots 513.

[0114] The core 500 fixes the conductors 203 in the upper conductor 300 and the lower conductor 400 respectively. Multiple conductors 203 in the upper conductor 300 and multiple conductors 203 in the lower conductor 400 are first assembled onto the core 500. Then, the transmission conductor 200 composed of the upper conductor 300, the lower conductor 400 and the core 500 is inserted into the insertion channel 101. This reduces the assembly difficulty of 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 embodiments of this application, the upper card slot 511 has an upper stop sidewall on the side opposite to 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 conductor 203 in the upper conductor 300 has an upper chamfer 304 at its end. The upper chamfer 304 cooperates with the upper stop side wall. The upper stop side wall can stop at the top of the upper chamfer 304, so that the conductor 203 in the upper conductor 300 is not easy to come out of the slot of the upper slot 511. This improves the reliability of the assembly of the conductor 203 and the core 500 and avoids the conductor 203 falling off and curling after too many insertion and removal cycles.

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

[0118] refer to Figure 7 The conductor element 203 in the lower conductor 400 has a downward chamfer 404 at its end. (Reference) Figure 16 The lower chamfer 404 and the lower stop side wall 514 stop each other. The lower stop side wall 514 can stop at the bottom of the lower chamfer 404, so that the conductor 203 in the lower conductor 400 is not easy to come out of the slot of the lower slot 513. This improves the reliability of the assembly of the conductor 203 and the core 500 and avoids the conductor 203 falling off and curling after too many insertion and removal cycles.

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

[0120] refer to Figure 17The transmission conductor 200 may further include a shielding sheet 600, which is sheet-shaped. (Reference) Figure 14 The shielding sheet 600 is inserted into the second slot 515 through the slot opening of the second 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 between the upper conductor 300 and the lower conductor 400 during high-speed signal transmission, so as to make the signal transmission more stable.

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

[0122] The first slot segment 5151 is closer to the input connection end 201 than the second slot segment 5152. The end of the first slot segment 5151 that is away from the second slot segment 5152 passes through the glue core 500 and forms the opening of the second card slot 515.

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

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

[0125] It should be noted that "fixed insertion" means that after the second part 620 is inserted into the second slot 5152, the second part 620 and the second slot 5152 are fixedly connected, and the second part 620 is tightly locked in the second slot 5152.

[0126] The shielding sheet 600 is secured to the core 500 by the second slot 515, which simplifies the assembly process of the shielding sheet 600 and the core 500 and improves the assembly efficiency of the shielding sheet 600 and the core 500.

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

[0128] refer to Figure 12 and Figure 13The upper surface of the core board 510 may be constructed with an upper slot 511, and the lower surface of the core board 510 may be constructed with a lower slot 513. Multiple conductors 203 in the upper conductor 300 are respectively secured within multiple upper slots 511. Multiple conductors 203 in the lower conductor 400 are respectively secured within multiple lower slots 513.

[0129] After the multiple conductors 203 in the upper conductor 300 are respectively secured in the multiple upper slots 511, and the multiple conductors 203 in the lower conductor 400 are respectively secured in the multiple lower slots 513, the upper conductor 300, the lower conductor 400, and the core board 510 constitute a whole (see reference). Figure 14 and Figure 17 ). refer to Figure 6 and Figure 17 The upper pressure plate 520 and the lower pressure plate 530 are pressed together at the top and bottom of the whole to form the transmission conductor 200.

[0130] The upper pressure plate 520 is pressed onto the top of the core plate 510 and the part of the upper conductor 300 near the input interface 110.

[0131] The lower pressure plate 530 is pressed onto the bottom of the core plate 510 and the part of the lower conductor 400 near the input interface 110.

[0132] The transmission conductor 200, which consists of a core board 510, an upper conductor 300, a lower conductor 400, an upper pressure plate 520, and a lower pressure plate 530, is assembled by first assembling the upper conductor 300 and the lower conductor 400 onto the core board 510, and then pressing the upper pressure plate 520 and the lower pressure plate 530 onto the top and bottom of the core board 510 on which the upper conductor 300 and the lower conductor 400 are assembled, to form the transmission conductor 200. This simplifies the assembly procedure of the upper conductor 300, the lower conductor 400, and the core 500, and improves the assembly efficiency of the upper conductor 300, the lower conductor 400, and the core 500.

[0133] Finally, the transmission conductor 200, consisting of the core plate 510, the upper conductor 300, the lower conductor 400, the upper pressure plate 520, and the lower pressure plate 530, is pressed into the insertion channel 101 together, thus completing the assembly between the transmission conductor 200 and the main frame 100. This simplifies the assembly procedure of the adapter 10 and improves the assembly efficiency of the adapter 10.

[0134] In some possible implementations of the embodiments of this application, reference is made to Figure 17 The adapter 10 may also 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 connected to the electrical interface 810, so that the adapter 10 is fixedly connected to the electrical interface 810 and the adapter 10 is not easily detached from the electrical interface 810.

[0135] refer to Figure 17 The fixed buckle 700 may have an elastic connecting part 710, a locking hook 720, a support part 730 and an unlocking part 740.

[0136] refer to Figure 8 The elastic connecting part 710 can extend approximately along the length direction X of the main frame 100. The elastic connecting part 710 can be in the form of a long strip plate or a long strip rod, etc. The elastic connecting part 710 has a certain degree of elasticity, that is, the elastic connecting part 710 can bend to a certain extent under the action of external force.

[0137] The flexible connection portion 710 can be embedded in the top of the input interface 110, and the portion of the flexible connection portion 710 near the output interface 120 is suspended.

[0138] The locking hook 720 can be block-shaped and is disposed on the top of the elastic connection part 710. The top end of the locking hook 720 extends above the top surface 112 of the input interface. The locking hook 720 is used to lock in the positioning hole 830 of the electrical interface when the input interface 110 is connected to the electrical interface 810.

[0139] The top of the support part 730 is connected to the end of the elastic connection part 710 that is away from the output interface 120, and the support part 730 is snapped into the main frame 100.

[0140] refer to Figure 10 and Figure 16 The top of the main frame 100 can be constructed with a first slot 103 facing upwards, as shown in the reference. Figure 16 The support part 730 can be fixedly inserted into the first slot 103, that is, the support part 730 is locked in the first slot 103 so that the support part 730 is not easy to come out of the first slot 103.

[0141] The bottom of the unlocking part 740 is connected to the end of the elastic connecting part 710 away from the support part 730. At least part of the unlocking part 740 is located in front of the input interface 110, so that after the input interface 110 is connected to the electrical interface 810, the unlocking part 740 will not be inserted into the electrical interface 810, but will be located in front of the electrical interface 810, so as to facilitate pressing the unlocking part 740.

[0142] refer to Figure 16 and Figure 17 The top of the output interface 120 has a clearance notch 123, the unlocking part 740 is housed in the clearance notch 123, and the top of the unlocking part 740 is not higher than the top surface 121 of the output interface 120.

[0143] When it is necessary to insert the input interface 110 into the electrical interface 810, simply align the input interface 110 and the electrical interface 810 until the locking hook 720 is engaged in the positioning hole 830 of the electrical interface (see reference). Figure 3 and Figure 16 This completes the docking of the input interface 110 and the electrical interface 810. Furthermore, because the locking hook 720 is engaged within the positioning hole 830 of the electrical interface, the input interface 110 is not easily removed from the electrical interface 810.

[0144] When it is necessary to remove the input interface 110 from the electrical interface 810, simply press down on the unlocking part 740. The unlocking part 740 will cause the end of the elastic connecting part 710 away from the support part 730 to move downward, and the top of the locking hook 720 will move 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 embodiments of this application, reference is made to Figure 16 and Figure 17 The main frame 100 may be constructed with a first limiting step 102, which is located within the clearance gap 123 and below at least a portion of the unlocking part 740.

[0146] When the unlocking part 740 is pressed down to abut against the first limit 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 releases its stop from the positioning hole 830 of the electrical interface. By pressing down the unlocking part 740 and moving the input interface 110 outward, the adapter 10 and the electrical interface 810 can be separated.

[0147] The first limiting step 102 can prevent the unlocking part 740 from moving too far downward when unlocking, which would cause the elastic connecting part 710 to bend too much and exceed the elastic limit, thus preventing it from rebounding and improving the service life of the fixing buckle 700.

[0148] In some possible implementations of the embodiments of this application, reference is made to Figure 10 and Figure 16 The main frame 100 may also be equipped with a clearance step 104, which is located below the portion of the elastic connection 710 near the output interface 120. The distance between the clearance step 104 and the top surface 112 of the input interface increases in the direction closer to the output interface 120. When the elastic connection 710 bends downward with the unlocking part 740, the space above the clearance step 104 can provide clearance for the elastic deformation of the elastic connection 710, allowing the elastic connection 710 to undergo elastic deformation, 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 embodiments of this application, reference is made to Figure 9 , Figure 10 and Figure 16 The main frame 100 may be constructed with a second limiting step 105, which stops the end of the core 500 away from the output interface 120. When the transmission conductor 200, consisting of the upper conductor 300, the lower conductor 400, and the core 500, is inserted into the insertion channel 101 from front to back, the second limiting step 105 stops the core 500 away from the output interface 120, thereby limiting the insertion position of the core 500 and improving the accuracy of the assembly between the transmission conductor 200 and the main frame 100.

[0150] It should be noted that in this embodiment, "forward" refers to the direction along the length direction X from the input interface 110 to the output interface 120. "Backward" refers to the direction along the length direction X from the output interface 120 to the input interface 110.

[0151] In some possible implementations of the embodiments of this 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] Multiple upper limit slots 106 can be located above slot 111, and multiple lower limit slots 107 can be located below slot 111. The bottom of the upper limit slot 106 and the side facing the output interface 120 are connected to slot 111.

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

[0154] Multiple upper limit slots 106 are arranged at intervals along the width direction Y, and multiple conductor elements 203 in the upper conductor 300 are respectively housed within the multiple upper limit slots 106. The conductor elements 203 in the upper conductor 300 can be inserted into the upper limit slots 106 on the side facing the output interface 120 via the upper limit slots 106, and can move up and down within the upper limit slots 106. The upper limit slots 106 can restrict the degrees of freedom of the conductor elements 203 in the upper conductor 300 along the width direction Y and the height direction Z, preventing the conductor elements 203 from shifting.

[0155] Multiple lower limit slots 107 are arranged at intervals along the width direction Y, and multiple conductor elements 203 in the lower conductor 400 are respectively accommodated in the multiple lower limit slots 107. The conductor elements 203 in the lower conductor 400 can be inserted into the lower limit slots 107 on the side facing the output interface 120 via the lower limit slots 107, and can move up and down within the lower limit slots 107. The lower limit slots 107 can restrict the degrees of freedom of the conductor elements 203 in the lower conductor 400 along the width direction Y and the height direction Z, so as to prevent the conductor elements 203 from shifting.

[0156] In some possible implementations of the embodiments of this application, reference is made to Figure 8 and Figure 17 The main frame 100 may also be constructed with a third limiting step 108, which is located on the side of the output interface 120 facing the input interface 110. The third limiting step 108 is used to stop at the front end 813 of the electrical interface. The third limiting step 108 is used to limit the insertion stroke of the input interface 110 into the electrical interface 810 of the optical module 800, so that the input interface 110 and the electrical interface 810 of the optical module 800 are accurately aligned.

[0157] In some possible implementations of the embodiments of this application, reference is made to Figure 8 The top of the output interface 120 may also be provided with a guide groove 127. The guide groove 127 is used to cooperate with the guide post or boss on the device under test so that the output interface 120 is precisely connected to the connector of the device under test, avoiding misalignment of the gold fingers of the output connection end 202 and the connector, and improving the reliability of the electrical connection between the gold fingers of the output connection end 202 and the connector.

[0158] In some possible implementations of the embodiments of this application, reference is made to Figure 3 The top of the output interface 120 can also be constructed with a limiting hole 128, which is used to position and cooperate with the connector of the device under test to improve the reliability of the output interface 120 after it is connected to the connector.

[0159] In some possible implementations of the embodiments of this application, reference is made to Figure 5 The bottom of the input interface 110 may be provided with a clearance groove 113, the opening of the clearance groove 113 facing downwards, and the clearance groove 113 passing through the main frame 100 on the side away from the output interface 120.

[0160] refer to Figure 16 The clearance 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 be moved from the side of the clearance groove 113 away from the output interface 120 into the clearance groove 113 so that the input interface 110 can reliably dock with the electrical interface 810.

[0161] In some possible implementations of the embodiments of this application, the front end of the upper guide plate 124 may be chamfered, the front end of the lower guide plate 125 may also be chamfered, and the chamfer at the front end of the output interface 120 is consistent with the chamfer at the front end of the electrical interface 810 of the optical module 800, so as to improve the smoothness of the connection between the output interface 120 and the connector of the device under test.

[0162] This application embodiment also provides a processing method for the above-mentioned adapter 10, which includes the following steps:

[0163] S110, Manufacturing Main Frame 100 (Reference) Figure 9 The main frame 100 has an input interface 110 and an output interface 120 arranged opposite to each other. The input interface 110 is used to insert into the electrical interface 810 of the optical module 800. The output interface 120 is used to insert into the optical cage of the device under test and mate with the connector of the device under test. The main frame 100 is configured such 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 lower 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 configured to be smaller than the length of the optical cage. The main frame 100 is provided with a insertion channel 101 extending in the length direction X.

[0164] The main frame 100 can be manufactured by integral casting. The material of the main frame 100 can be polyetheretherketone (PEEK) to give the main frame 100 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 terminal 201 and an output connection terminal 202 at its two ends along its extension direction. The input connection terminal 201 is used for electrical connection with the gold finger 820 at the electrical interface 810. The output connection terminal 202 is used for electrical connection with the gold finger at the connector.

[0166] S130. Press the transmission conductor 200 into the insertion channel 101, and extend the input connection terminal 201 into the input interface 110, and extend the output connection terminal 202 into the output interface 120 (see reference). Figure 11 ).

[0167] The adapter 10 manufactured by the processing method of the adapter 10 in this application embodiment has an output interface top surface 121 that is not higher than the electrical interface top surface 811 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 output interface top surface 121 is below the height of the electrical interface top surface 811. The output interface top surface 121 can be flush with the electrical interface top surface 811, or the output interface top surface 121 can be lower than the electrical interface top surface 811.

[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 10 is inserted into the electrical interface 810 of the optical module 800, the optical module 800 and the adapter 10 form a whole. At this time, when the output interface 120 of the adapter 10 is inserted into the optical cage of the device under test, since 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 part of the electrical interface 810 of the optical module 800 is inserted into the optical cage of the device under test, enabling the adapter 10 to transmit data between the optical module 800 and the device under test. Compared with the adapter card in the related art, the adapter 10 of this application embodiment reduces the length of the adapter 10, thereby shortening the length of the signal integrity link of the adapter 10, reducing signal attenuation, and improving the transmission rate of the adapter 10.

[0170] Step S120 includes:

[0171] S121, Manufacturing core board 510 (reference) Figure 12 The upper surface of the core board 510 has multiple upper slots 511, the lower surface of the core board 510 has multiple lower slots 513, and the side of the core board 510 has a second slot 515.

[0172] The core board 510 can be made of polydecanediamine terephthalamide, so that the core board 510 has the advantages of wear resistance, easy molding, and good moldability. The core board 510 is integrally cast.

[0173] S122, Multiple conductor elements 203 for manufacturing the upper conductor 300 and multiple conductor elements 203 for manufacturing the lower conductor 400 (see reference) Figure 7 ).

[0174] The conductor 203 is made of copper-nickel-silicon alloy, which has excellent bending performance, high strength, good corrosion resistance, and high conductivity, making it suitable for high-speed signal transmission. The conductor 203 is manufactured by ultra-precision one-piece stamping.

[0175] S123, Manufacturing the upper pressure plate 520 and the lower pressure plate 530 (reference) Figure 17 ).

[0176] Both the upper pressure plate 520 and the lower pressure plate 530 can be made of polydecylated diamine terephthalamide, giving them advantages such as wear resistance, ease of molding, and good moldability. The upper pressure plate 520 and the lower pressure plate 530 are manufactured by machining.

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

[0178] The shielding sheet 600 is made of phosphor bronze strip, which features high strength, elasticity, wear resistance, and antimagnetic properties. The shielding sheet 600 is manufactured using die stamping.

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

[0180] S126. Press the multiple conductors 203 of the upper conductor 300 into the multiple upper slots 511 respectively, and press the multiple conductors 203 of the lower conductor 400 into the multiple lower slots 513 respectively, to form a first integral unit (refer to...). Figure 14 ).

[0181] Before pressing the conductor 203 of the upper conductor 300 into the upper slot 511 and the conductor 203 of the lower conductor 400 into the lower slot 513, a small amount of solid adhesive can be applied to the bottom of the upper slot 511 and the lower slot 513 to bond the conductor 203 and improve the reliability of the connection between the conductor 203 and the core board 510.

[0182] The conductor 203 and the core plate 510 are placed on the mold, and then heated and pressurized to make the conductor 203 more securely fixed in the upper slot 511 and the lower slot 513. Furthermore, the width direction Y of the conductor 203 and the dimensions of the upper slot 511 and the lower slot 513 are tightly fitted.

[0183] S127, Reference Figure 17 The upper pressure plate 520 is placed on top of the first integral piece, and the lower pressure plate 530 is placed on the bottom of the first integral piece. After compaction, a clamp is used to secure the position, forming the transmission conductor 200 (reference). Figure 6 ).

[0184] The processing method of the adapter 10 provided in this application embodiment further includes:

[0185] S140, Manufacturing fixing buckle 700 (reference) Figure 17 The 700 fixed buckle is used to connect with the electrical interface 810.

[0186] The fixing buckle 700 may include a resilient connecting part 710, a locking hook 720, a supporting part 730, and an unlocking part 740. The materials of each part of the fixing buckle 700 may be high-elasticity shape memory alloy.
