[0002] When existing devices or equipment are electrically connected, they usually use a straight male connector and a curved female connector. When the straight male connector and the curved female connector are mated, the head shell of the curved female connector needs to be inserted into the bottom shell of the straight male connector to limit the position. If the connection terminals of the straight male connector and the connection terminals of the curved female connector are not properly plugged in, the signal transmission quality will be affected. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a computing device and a connector assembly, wherein the computing device can effectively limit the contact of the terminal connection assembly through a fixing part, thereby controlling the insertion depth of the terminal connection assembly in the connector, thereby ensuring the quality of signal transmission between the connector assembly and the terminal connection assembly.

[0004] An embodiment of the present application provides a computing device, the computing device comprising a connector assembly and a terminal connection assembly, the connector assembly comprising a first circuit board, a connector and a fixing member, the connector and the fixing member are both mounted on the first circuit board, the fixing member is arranged on the outer side of the connector and forms a slot;

[0005] The terminal connection assembly can be adaptively plugged into the connector along the slot, and the connector assembly contacts and limits the terminal connection assembly through the fixing piece.

[0006] In the computing device provided in the embodiment of the present application, by arranging a fixing part on the outside of the connector and using the fixing part to limit the contact of the terminal connection assembly, the insertion depth of the terminal connection assembly in the connector can be effectively controlled, thereby solving the problem that the connector itself has no limiting ability, and ensuring the signal integrity (SI) of the electrical connection between the connector and the terminal connection assembly, thereby ensuring the quality of signal transmission between the connector assembly and the terminal connection assembly.

On the one hand, the first fixing member is used to contact and limit the fixing portion of the mounting member, so that the connector contacts and limits the fixing portion of the mounting member through the first fixing member, and then the connector assembly contacts and limits the terminal connection assembly through the first fixing member, which effectively avoids the problem of over-insertion or insufficient insertion depth of the terminal connector of the terminal connection assembly and the connector, improves the reliable plug-in between the terminal connection assembly and the connector assembly, and then ensures the signal transmission quality between the terminal connection assembly and the connector assembly.

Among them, along the thickness direction of the fixing portion 311 of the mounting member 310, the third end face 72a is flush with the fourth end face 73a, and the first end face 303a of the first fixing member 30 protrudes toward the fixing portion 311 relative to the second end face 422a of the second fixing member 40, so that the first end face 303a of the first fixing member 30 and the third end face 72a of the fixing portion 311 are contacted and limited, and a gap is formed between the second end face 422a of the second fixing member 40 and the fourth end face 73a of the fixing portion 311, so that the second fixing member 40 does not participate in the contact and limit. In this embodiment, the gap between the second end face 422a of the second fixing member 40 and the fourth end face 73a of the fixing portion 311 is D.

[0095] When assembling the electronic module 1100 and the backplane system 1200, the electronic module 1100 is pushed toward the backplane system 1200 so that the guide portion 312 of the mounting member 310 of the terminal connection assembly 300 in the backplane system 1200 is sequentially extended into the guide groove 46 of the second fixing member 40 and the guide hole 35 of the first fixing member 30 of the connector assembly 100 in the electronic module 1100, so as to guide the terminal connection member 330 of the terminal connection assembly 300 to be plugged into the connector 20 of the connector assembly 100 along the slot 60, thereby improving the assembly accuracy of the terminal connection assembly 300 and the connector assembly 100. During the movement of the electronic module 1100, the connection end 203 of the connector 20 in the connector assembly 100 moves toward the terminal connector 330 of the terminal connector assembly 300, the first end 81 of the second circuit board 80 in the terminal connector 330 passes through the slot 60 surrounded by the first fixing member 30 and the second fixing member 40 in the connector assembly 100, and is plugged with the connection end 203 of the connector 20 arranged on the inner side of the first fixing member 30, and the conductive terminal 90 installed on the first end 81 contacts and slides relatively with the connection terminal of the connection end 203. When the first end face 303a of the first fixing member 30 in the connector assembly 100 is in contact with the third end face 72a of the fixing portion 311 of the mounting member 310 in the terminal connector assembly 300 of the backplane system 1200, the electronic module 1100 stops moving, so that the connector assembly 100 can limit the contact of the terminal connector assembly 300 along the Y-axis direction. There is a gap between the second end face 422a of the second fixing member 40 in the connector assembly 100 and the fourth end face 73a of the fixing portion 311 of the mounting member 310, and the gap does not participate in the position limiting in the Y-axis direction. The relative sliding distance of the conductive terminal 90 relative to the connecting terminal of the connecting end 203 is L, that is, the distance between the end of the conductive terminal 90 away from the fixing portion 311 of the mounting member 310 and the contact point between the conductive terminal 90 and the connecting terminal of the connecting end 203 is L.

[0096] Since the plug-in and pull-out specifications of the connector 20 limit the sliding depth of the conductive terminal 90 relative to the connecting terminal of the connecting end 203 in the connector 20, that is, limit the distance L, to avoid the conductive terminal 90 being inserted too deep or too shallow relative to the connector 20 to affect the signal reliability, and the connector 20 also requires a reliability friction distance ≥ 0.51mm, while the connector 20 itself has no limiting capability. The embodiment of the present application sets a fixing member 51 on the outside of the connector 20, and uses the fixing member 51 to contact and limit the terminal connector 330, which can effectively control the insertion depth of the terminal connector 330 in the connector 20, solves the problem that the connector 20 itself has no limiting capability, and ensures the signal integrity (SI) between the connector 20 and the conductive terminal 90 in the terminal connector 330, thereby ensuring the quality of signal transmission between the connector assembly 100 and the terminal connection assembly 300.

[0097] In addition, the embodiment of the present application sets a first fixing member 30, and utilizes the first fixing member 30 to be set on the outside of the connector 20, and the first end face 303a of the first fixing member 30 toward the fixing portion 311 of the mounting member 310 is contacted and limited with the fixing portion 311 to control the sliding depth of the connecting terminal of the connecting end 203 of the connector 20 relative to the conductive terminal 90, thereby controlling the insertion depth of the conductive terminal 90 of the terminal connector 330 in the connector 20, thereby achieving the contact and limitation of the connector 20 on the fixing portion 311 of the mounting member 310 through the first fixing member 30, and then achieving the contact and limitation of the connector assembly 100 on the terminal connection assembly 300 through the first fixing member 30, effectively avoiding the problem of over-insertion or insufficient insertion depth of the terminal connection assembly 330 of the terminal connection assembly 300 and the connector 20, improving the reliable plug-in between the terminal connection assembly 300 and the connector assembly 100, and then ensuring the signal transmission quality between the terminal connection assembly 300 and the connector assembly 100. In addition, compared with the existing intermate method of straight male connectors and bent female connectors, the plug-in method of connector 20 and terminal connector 330 in the embodiment of the present application has low loss, can improve the system signal gain, and does not require the use of customized connectors, thereby reducing the cost of connector customization.

[0098] In addition, the tolerance of the assembly structure of the terminal connection assembly 300 and the connector assembly 100 includes a tolerance in the Y-axis limiting direction, specifically including the first positioning portion 32 of the first fixing member 30 (see Figure 7 ) to the first end face 303a, the tolerance A1, the stopper 71 (see Fig.10 ) to the fourth end surface 73a of the fixing portion 311 and the second positioning hole 16 of the first circuit board 10 (see Figure 3 ) to the connection terminal of the connection end 203 of the connector 20. In the embodiment of the present application, by setting the first end face 303a of the first fixing member 30 facing the fixing portion 311 to contact and limit the fixing portion 311, and setting a gap between the second end face 422a of the second fixing member 40 facing the fixing portion 311 and the fourth end face 73a of the fixing portion 311, while realizing the contact and limiting of the first fixing member 30 on the terminal connection assembly 300, since the second fixing member 40 does not participate in the limiting, the tolerance of the distance between the second end face 422a of the second fixing member 40 and the fourth end face 73a of the fixing portion 311 does not need to be included in the number of tolerance chains in the limiting direction, thereby reducing the number of tolerance chains in the limiting direction to ensure that the number of tolerance chains in the limiting direction is minimal, reducing the tolerance of the assembly structure of the terminal connection assembly 300 and the connector assembly 100, and ensuring the highest accuracy of the assembly structure. Exemplarily, the tolerance A1 is ±0.1 mm, the tolerance A2 is ±0.05 mm, and the tolerance A3 is A2 ±0.013 mm.

[0099] Furthermore, by providing a second fixing member 40, the second fixing member 40 can also be enclosed with the first fixing member 30 to form a slot 60, so as to guide the first end portion 81 of the second circuit board 80 to pass through the slot 60 so that the conductive terminal 90 is electrically connected to the connecting terminal of the connecting end 203 of the connector 20, thereby facilitating the guidance of the plug-in connection between the terminal connection assembly 300 and the connector assembly 100.

[0100] See also Fig.15 , Fig.15 It is a structural schematic diagram of a connector assembly 100 in a computing device 1000 according to a second embodiment of the present application.

[0101] The computing device 1000 of the second embodiment has the same structure as the computing device 1000 of the first embodiment, except that the number of connectors 20 and slots 60 in the connector assembly 100 of the computing device 100 of the second embodiment is one, and the number of terminal connectors 330 in the terminal connection assembly 300 is one.

[0102] Specifically, the second shell portion 362 of the fixing shell 36 in the first fixing member 30 and the second mounting portion 412 of the mounting portion 41 in the second fixing member 40 are enclosed to form a slot 60. The second circuit board 80 of one terminal connector 330 is provided with one slot 60 and plugged with one connector 20, and the conductive terminal 90 mounted on the second circuit board 80 of one terminal connector 330 is electrically connected with one connector 20.

[0103] In other embodiments, the number of connectors 20 in the connector assembly 100 of the computing device 1000 may also be three. At this time, the second shell portion 362 of the fixed shell 36 in the first fixing member 30 and the second mounting portion 412 of the mounting portion 41 in the second fixing member 40 enclose three slots 60, the number of terminal connectors 330 is three, and the second circuit boards 80 of the three terminal connectors 330 are respectively provided with three slots 60, and are respectively plugged with three connectors 20, and the conductive terminals 90 installed on the second circuit board 80 of each terminal connector 330 are electrically connected to one connector 20. It should be understood that the number of connectors 20 in the connector assembly 100 of the computing device 1000 may also be four, five, etc., and the embodiment of the present application does not limit the number of connectors 20 in the computing device 1000.

[0104] See also Fig.16 , Fig.16 It is a cross-sectional structural diagram of the assembly structure of the connector assembly 100 and the terminal connection assembly 300 in the computing device 1000 of the third embodiment of the present application.

[0105] The computing device 1000 of the third embodiment has the same structure as the computing device 1000 of the first embodiment, except that the first surface 311a of the fixing portion 311 of the mounting member 310 in the terminal connection assembly 300 of the computing device 1000 of the third embodiment includes a third end surface 72b and a fourth end surface 73b, and the third end surface 72b and the fourth end surface 73b are not flush.

[0106] Specifically, in the terminal connection assembly 300, the first end surface 303a of the first fixing member 30 protrudes toward the fixing portion 311 relative to the second end surface 422a of the second fixing member 40, such as Fig.16 As shown, the first end face 303a protrudes relative to the second end face 422a by a distance D. The third end face 72b of the second fixing portion 314 in the fixing portion 311 of the mounting member 310 protrudes toward the first fixing member 30 relative to the fourth end face 73b of the first fixing portion 313, as shown in FIG. Fig.16 As shown, along the width direction of the fixing portion 311, the third end face 72a protrudes relative to the fourth end face 73b along the Y-axis direction by a distance of H, so that when the third end face 72b is in contact with the first end face 303a of the first fixing member 30, the second fixing member 40 does not participate in the contact limit. In this embodiment, the gap between the second end face 422a of the second fixing member 40 and the fourth end face 73b of the fixing portion 311 is D+H.

[0107] In this embodiment, the second fixing member 40 does not participate in the contact limiting, thereby reducing the number of tolerance chains in the limiting direction to ensure that the number of tolerance chains in the limiting direction is minimized, reducing the tolerance of the assembly structure of the terminal connection component 300 and the connector component 100, and ensuring the highest accuracy of the assembly structure.

[0108] See also Fig.17 , Fig.17 It is a schematic cross-sectional structural diagram of the assembly structure of the connector assembly 100 and the terminal connection assembly 300 in the computing device 1000 of the fourth embodiment of the present application.

[0109] The computing device 1000 of the fourth embodiment has the same structure as the computing device 1000 of the first embodiment, except that the fixing member body 31 of the first fixing member 30 in the connector assembly 100 of the computing device 1000 of the fourth embodiment includes a first end surface 303c, the second mounting portion 412 of the second fixing member 40 includes a second end surface 422c, the first end surface 303c is flush with the second end surface 422c of the second fixing member 40, and the first surface 311a of the fixing portion 311 of the mounting member 310 in the terminal connection assembly 300 includes a third end surface 72c and a fourth end surface 73c, and the third end surface 72c protrudes toward the first fixing member 30 relative to the fourth end surface 73c, as shown in FIG. Fig.17As shown, along the width direction of the fixing portion 311, that is, along the Y-axis direction, the third end surface 72a protrudes relative to the fourth end surface 73a by a distance H.

[0110] Specifically, in the connector assembly 100, the first end face 303c of the first fixing member 30 and the second end face 422c of the second fixing member 40 are approximately located in the same plane. Since the third end face 72c of the fixing portion 311 of the mounting member 310 protrudes toward the first fixing member 30 relative to the fourth end face 73c, when the first end face 303c of the first fixing member 30 and the third end face 72c of the fixing portion 311 are abutted and limited, the second fixing member 40 does not participate in the contact and limit. In this embodiment, the gap between the second end face 422c of the second fixing member 40 and the fourth end face 73c of the fixing portion 311 is H.

[0111] In this embodiment, the second fixing member 40 does not participate in the contact limiting, thereby reducing the number of tolerance chains in the limiting direction to ensure that the number of tolerance chains in the limiting direction is minimized, reducing the tolerance of the assembly structure of the terminal connection component 300 and the connector component 100, and ensuring the highest accuracy of the assembly structure.

[0112] See also Fig.18 , Fig.18 It is a schematic cross-sectional structural diagram of the assembly structure of the connector assembly 100 and the terminal connection assembly 300 in the computing device 1000 of the fifth embodiment of the present application.

[0113] The computing device 1000 of the fifth embodiment has the same structure as the computing device 1000 of the first embodiment, except that the fixing member body 31 of the first fixing member 30 in the connector assembly 100 of the computing device 1000 of the fifth embodiment includes a first end face 303d, the second mounting portion 412 in the second fixing member 40 includes a second end face 422d, the first end face 303d of the first fixing member 30 is flush with the second end face 422d of the second fixing member 40, and the first face 311a of the fixing portion 311 of the mounting member 310 in the terminal connection assembly 300 includes a third end face 72d and a fourth end face 73d, and the third end face 72d is flush with the fourth end face 73d.

[0114] Specifically, in the connector assembly 100, the first end face 303d of the first fixing member 30 and the second end face 422d of the second fixing member 40 are approximately located in the same plane. In the terminal connection assembly 300, the third end face 72d and the fourth end face 73d of the mounting member 310 are approximately located in the same plane. When the first end face 303d of the first fixing member 30 abuts against the third end face 72d of the fixing portion 311, the second end face 422d of the second fixing member 40 abuts against the fourth end face 73d of the fixing portion 311, thereby achieving that both the first fixing member 30 and the second fixing member 40 participate in contact limiting.

[0115] In this embodiment, the contact limit function of the first fixing member 30 and the second fixing member 40 can effectively control the insertion depth of the terminal connector 330 in the connector 20, effectively avoiding the problem of over-insertion or insufficient insertion depth of the terminal connector 330 and the connector 20, improving the reliable connection between the terminal connection component 300 and the connector component 100, and ensuring the signal integrity (SI) of the electrical connection between the connector 20 and the terminal connection component 300, thereby ensuring the transmission quality of the signal between the terminal connection component 300 and the connector component 100, and solving the problem that the connector 20 itself has no limiting ability.
