Description

Technical Field

[0002] CPO switches, or Co-Packaged Optics switches, are innovative devices that integrate the optical engine and the switch's ASIC (Application Specific Integrated Circuit) chip onto the same substrate. In traditional optical communication systems, the optical module and the switch chip are independent, connected to the switch PCB via pluggable interfaces. Electrical signals must travel through several centimeters of PCB traces, which not only exacerbates signal attenuation but also limits data transmission rate and efficiency. CPO switches break this traditional model, achieving deep integration of optoelectronics.

[0033] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "inner," "outer," "vertical," "horizontal," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0036] Please see Figures 1 to 5 This application provides an electrical connector 100, which includes a plurality of first grounding terminal assemblies 10, a plurality of second grounding terminal assemblies 20, and a plurality of high-speed signal terminal assemblies 30. The plurality of first grounding terminal assemblies 10 extend along a first direction X and are spaced apart in a second direction Y to form first spacer cavities.

[0037] Please see Figure 7 and Figure 8 The first grounding terminal assembly 10 includes a shielding plate 11 and an elastic member 12. The shielding plate 11 is located in the plane formed by the first direction X and the third direction Z. The elastic member 12 is fitted to the shielding plate 11 and includes a central shaft portion 121, a plurality of first elastic arms 122 connected above the central shaft portion 121, and a plurality of second elastic arms 123 connected below the central shaft portion 121. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. A plurality of second grounding terminal assemblies 20 and a plurality of high-speed signal terminal assemblies 30 are all disposed in the first spacer cavity. The second grounding terminal assemblies 20 and the high-speed signal terminal assemblies 30 are alternately and spaced apart in the first direction X.

[0038] Compared to the existing technology where the grounding terminal assembly is flat and intersecting in both the first direction X and the second direction Y, resulting in a large volume, the electrical connector 100 of this application improves the structure of the first grounding terminal assembly 10, making the thickness of the first grounding terminal assembly 10 in the second direction Y thinner. This allows for the arrangement of a larger number of first grounding terminal assemblies 10, thereby improving the grounding shielding effect, enhancing signal transmission quality, or reducing the overall size of the electrical connector 100 in the second direction Y, thus contributing to miniaturization design.

[0039] In some embodiments, please refer to Figure 7 and Figure 8 The central shaft portion 121 is elongated along the first direction X; a plurality of first elastic arms 122 are arranged on the same side of the central shaft portion 121 and spaced apart in the first direction X, and each first elastic arm 122 is bent in the third direction Z; so that the first elastic arm 122 has an approximately S-shaped bending structure, thereby having elastic deformation capability in the third direction Z. The free end of the first elastic arm 122 protrudes from the shielding plate 11 in the third direction Z to facilitate contact with the conductive part of the external chip.

[0040] Several second elastic arms 123 are spaced apart on the other side of the central shaft portion 121 in the first direction X. Each second elastic arm 123 is bent in the third direction Z, so that the second elastic arm 123 has an approximately S-shaped bending structure, thereby having elastic deformation capability in the third direction Z. The free end of the second elastic arm 123 protrudes from the shielding plate 11 in the third direction Z to facilitate contact with the conductive part of the external circuit board 200.

[0041] The first elastic arm 122 and the second elastic arm 123 are located in the same plane, which can reduce the space between the first elastic arm 122 and the second elastic arm 123 in the second direction Y, thereby reducing the space occupied by the first grounding terminal assembly 10 in the second direction Y.

[0042] In some embodiments, the central shaft portion 121 may not be coplanar with the first elastic arm 122 and the second elastic arm 123. The central shaft portion 121 and the two arms may be offset in the second direction Y. For example, the central shaft portion 121 may be fitted to the shielding plate 11, and a portion of the first elastic arm 122 and the second elastic arm 123 may be spaced apart from the shielding plate 11 in the second direction Y. This can reduce the friction between the first elastic arm 122 and the second elastic arm 123 and the shielding plate 11, and further improve their elastic performance. Of course, it is preferable that the distance between the first elastic arm 122 and the second elastic arm 123 and the shielding plate 11 in the second direction Y is within 8 mm. If the distance is too large, it will increase the overall thickness of the first grounding terminal assembly 10 in the second direction Y.

[0043] In some embodiments, the central shaft portion 121, the first elastic arm 122, and the second elastic portion can be arranged in a coplanar manner, which helps to reduce the thickness of the first grounding terminal assembly 10 in the second direction Y.

[0044] It is understandable that, compared to the structure where the elastic element 12 has only one elastic arm and requires multiple independent elastic elements 12, the elastic element 12 in this application is connected to multiple first elastic arms 122 and second elastic arms 123 simultaneously through a central shaft portion 121. This reduces the number of parts, facilitates processing, and improves production and assembly efficiency. Furthermore, since multiple first elastic arms 122 and multiple second elastic arms 123 are connected through the central shaft portion 121, the grounding effect of the entire elastic element 12 is improved, making the grounding shielding effect of the shielding plate 11 uniform. Moreover, when one of the first elastic arms 122 or second elastic arms 123 fails to make good contact with the external chip or circuit board 200, the first elastic arm 122 or second elastic arm 123 can be connected to other first elastic arms 122 and second elastic arms 123 that are in good contact through the central shaft portion 121, so that the first elastic arm 122 or second elastic arm 123 that is not in good contact also has a good grounding shielding effect.

[0045] In some embodiments, please refer to Figure 7 and Figure 8 The shielding plate 11 is provided with a first positioning structure 113. The first elastic arm 122 and / or the second elastic arm 123 of the elastic member 12 and the central shaft portion 121 can form a second positioning structure 124 that cooperates with the first positioning structure 113. The second positioning structure 124 is used to cooperate with the first positioning structure 113 to achieve positioning.

[0046] The shielding plate 11 and the elastic element 12 can be two independent components, which are assembled into the first grounding terminal assembly 10 through secondary assembly. During the assembly of the shielding plate 11 and the elastic element 12, it is necessary to position them to facilitate subsequent assembly and mass production of the first grounding terminal assembly 10 with the same specifications.

[0047] As an example, the shielding plate 11 has a through hole in the second direction Y, which constitutes the first positioning structure 113. The connection between the first elastic arm 122 and the central shaft portion 121 can constitute the second positioning structure 124, or the connection between the second elastic arm 123 and the central shaft portion 121 can constitute the second positioning structure 124. In this way, external positioning posts and other structures can pass through the through hole on the shielding plate 11 and be engaged and fixed with the elastic element 12, thereby achieving the positioning of the shielding plate 11 and the elastic element 12. Subsequently, the central shaft portion 121 can be connected and fixed to the shielding plate 11 by laser welding, bonding, or other methods.

[0048] In this application, the connection between the first elastic arm 122 and / or the second elastic arm 123 and the central shaft portion 121 is cleverly configured to form a second positioning structure 124, so that it is not necessary to drill holes in the central shaft portion 121, thus ensuring that the central shaft portion 121 has sufficient structural strength.

[0049] In some embodiments, please refer to Figures 4 to 6 The electrical connector 100 includes an insulating base 40, which has a plurality of first grooves 41 extending along a first direction X. A first grounding terminal assembly 10 is disposed within the first grooves 41. A shielding plate 11 has a first fixing part 111 at its end in the first direction X, which abuts against the groove wall of the first groove 41. By providing the first fixing part 111 at the end of the shielding plate 11 and interlocking it with the inner wall of the first groove 41, the first grounding terminal assembly 10 can be quickly assembled onto the insulating base 40 without the need for other screws. In addition, since the shielding plate 11 is connected and fixed to the insulating base 40, the elastic member 12 is not directly connected and fixed to the insulating base 40, which allows the elastic member 12 to maintain its elasticity and facilitates contact with the circuit board 200 and the chip.

[0050] It is understandable that when the elastic element 12 is not compressed, the free ends of the first elastic arm 122 and the second elastic arm 123 both extend out of the first groove 41.

[0051] In some embodiments, please refer to Figures 4 to 6 The first groove 41 penetrates the insulating seat 40 in the third direction Z. The insulating seat 40 is provided with a first blocking part 42, which is located at the top of the first groove 41 in the third direction Z. The shielding plate 11 is provided with a first notch 112 at the top in the third direction Z. When the shielding plate 11 is engaged in the first groove 41, the first notch 112 and the first blocking part 42 are fitted together. The first blocking part 42 has a blocking effect on the shielding plate 11, preventing the shielding plate 11 from passing through the first groove 41 in the third direction Z.

[0052] By providing a first blocking part 42 at the top of the first groove 41, the first grounding terminal assembly 10 can be inserted into the first groove 41 from the bottom upwards. Since the bottom of the insulating base 40 is fixedly connected to the circuit board 200, the first grounding terminal assembly 10 is fixed within the first groove 41 under the combined clamping action of the first blocking part 42 and the circuit board 200 in the third direction Z. This simplifies assembly and the fixing structure. Furthermore, due to the clamping action of the circuit board 200, the bottom of the shielding plate 11 does not need to have notches for fixing. Only several first notches 112 need to be made at the top of the shielding plate 11 to fit and connect with the first blocking part 42. This maximizes the area and structural integrity of the shielding plate 11, thereby improving its grounding shielding effect.

[0053] In some embodiments, the insulating base 40 is provided with a second groove 43 extending through the third direction Z; and in the second direction Y, the second groove 43 is located between two adjacent first grooves 41, wherein the first grooves 41 may or may not be connected to the second grooves 43 in the second direction Y.

[0054] The high-speed signal terminal assembly 30 is disposed in the second groove 43, and both ends of the high-speed signal terminal assembly 30 protrude from the second groove 43 in the third direction Z, so that the high-speed signal terminal assembly 30 can be elastically connected to the chip and the circuit board 200. The high-speed signal terminal assembly 30 includes a first signal terminal 31 and a second signal terminal 32 that are independent of each other and spaced apart in the second direction Y.

[0055] In some embodiments, please refer to Figure 9 The first signal terminal 31 includes a first portion 311 and a second portion 312 and a third portion 313 bent and connected to both ends of the first portion 311, wherein the second portion 312 and the third portion 313 are elastically deformable relative to the first portion 311 in a third direction Z. The first portion 311 is fixedly connected to the insulating base 40. As an example, at least a portion of the first portion 311 is interference-fitted to the inner wall of the second groove 43. The end of the second portion 312 away from the first portion 311 is provided with a first abutment portion 314, and the end of the third portion 313 away from the first portion 311 is provided with a second abutment portion 315.

[0056] When not under pressure, a portion of the second part 312 and the first abutment part 314 extend a second groove 43 in the third direction Z. The first abutment part 314 is used to contact and connect with the conductive part of the external chip to realize signal transmission between the chip and the first signal terminal 31. When not under pressure, a portion of the third part 313 and the second abutment part 315 extend a second groove 43 in the third direction Z. The second abutment part 315 is used to contact and connect with the conductive part of the external circuit board 200 to realize signal transmission between the first signal terminal 31 and the circuit board 200.

[0057] Similarly, the second signal terminal 32 includes a fourth portion 321 and a fifth portion 322 and a sixth portion 323 bent and connected to both ends of the fourth portion 321, wherein the fourth portion 321 and the fifth portion 322 are elastically deformable relative to the fourth portion 321 in a third direction Z. The fourth portion 321 is fixed to the insulating base 40, and as an example, at least a portion of the fourth portion 321 is interference-fitted to the inner wall of the second groove 43. The end of the fifth portion 322 away from the fourth portion 321 is provided with a third abutment portion 324, and the end of the sixth portion 323 away from the fourth portion 321 is provided with a fourth abutment portion 325.

[0058] When not under pressure, a portion of the fifth part 322 and the third abutment part 324 extend a second groove 43 in the third direction Z. The third abutment part 324 is used to contact and connect with the conductive part of the external chip to realize signal transmission between the chip and the second signal terminal 32. When not under pressure, a portion of the sixth part 323 and the fourth abutment part 325 extend a second groove 43 in the third direction Z. The fourth abutment part 325 is used to contact and connect with the conductive part of the external circuit board 200 to realize signal transmission between the second signal terminal 32 and the circuit board 200.

[0059] In some embodiments, please refer to Figure 9 and Figure 11 The second part 312 is provided with a first protrusion 3121; and / or, the third part 313 is provided with a second protrusion 3131; and / or, the fifth part 322 is provided with a third protrusion 3221; and / or, the sixth part 323 is provided with a fourth protrusion 3231. Through the above structural arrangement, the local thickness of the second part 312, the third part 313, the fourth part 321, and the fifth part 322 can be increased, thereby increasing their cross-sectional area and reducing their impedance. This helps to improve the signal transmission efficiency and quality of the first signal terminal 31 and the second signal terminal 32, and reduces signal transmission distortion.

[0060] In some embodiments, please refer to Figures 9 to 11 ,in Figure 9 and Figure 10 Two high-speed signal terminal assemblies 30 with different structures are shown. They are similar in structure, and the main difference is: Figure 9 In the example, the high-speed signal terminal assembly 30 does not have a corresponding bent extension. Figure 10 In the example, the high-speed signal terminal assembly 30 is provided with opposing curved extensions.

[0061] As an example, please refer to Figure 10 and Figure 11 The second part 312 has a first curved extension 3122 on the side near the fifth part 322, and the fifth part 322 has a second curved extension 3222 on the side near the second part 312. The first curved extension 3122 and the second curved extension 3222 are spaced apart and opposite to each other in the second direction Y. At least a portion of the first curved extension 3122 and the second curved extension 3222 are arranged face to face and parallel.

[0062] The third part 313 has a third curved extension 3132 on its side near the sixth part 323, and the sixth part 323 has a fourth curved extension 3232 on its side near the third part 313. The third curved extension 3132 and the fourth curved extension 3232 are spaced apart and opposite to each other in the second direction Y, and at least a portion of the third curved extension 3132 and the fourth curved extension 3232 are arranged face to face and parallel.

[0063] By adopting the above-described structural configuration, the overlapping area of ​​the projection of the first signal terminal 31 and the second signal terminal 32 in the second direction Y can be increased, the mutual capacitance and inductance of the first signal terminal 31 and the second signal terminal 32 can be enhanced, the mutual coupling effect between the two can be improved, and the transmission performance of the high-speed signal terminal assembly 30 can be improved, thereby enhancing the transmission integrity of high-speed signals.

[0064] In some embodiments, please refer to Figure 6 and Figure 12 The insulating base 40 is provided with a third groove 44 extending through in the third direction Z. The third groove 44 and the second groove 43 are spaced apart and alternately arranged in the first direction X. The second grounding terminal assembly 20 is disposed in the third groove 44. The second grounding terminal assembly 20 includes a first terminal 21, a second terminal 22, and a connecting portion 23 connecting the first terminal 21 and the second terminal 22. At least a portion of the connecting portion 23 is press-fitted with the inner wall of the third groove 44 so that the second grounding signal terminal assembly is fixed in the third groove 44.

[0065] The second grounding terminal assembly 20 and the high-speed signal terminal assembly 30 are spaced apart and alternately arranged in the first direction X. In this way, the second grounding terminal assembly 20 and the first grounding terminal assembly 10 can work together to provide grounding shielding for two adjacent high-speed signal terminal assemblies 30, reduce the probability of crosstalk between the two high-speed signal terminal assemblies 30, and thus ensure the transmission quality of high-speed signals.

[0066] In some embodiments, please refer to Figure 2The electrical connector 100 also includes a housing 50, which has a receiving cavity 51, and an insulating seat 40 is disposed within the receiving cavity 51. The housing 50 includes a first sidewall 52 and a second sidewall 53 disposed opposite each other in a first direction X. The first sidewall 52 has a first elastic plate 521, which bends and protrudes toward the receiving cavity 51 and is used to abut against the insulating seat 40. And / or, the second sidewall 53 has a second elastic plate 531, which bends and protrudes toward the receiving cavity 51 and is used to abut against the insulating seat 40. The housing 50 includes a third sidewall 54 and a fourth sidewall 55 disposed opposite each other in the second direction Y. The third sidewall 54 is provided with a third elastic plate 541, which is bent and protrudes toward the receiving cavity 51 and is used to abut against the insulating seat 40. The fourth sidewall 55 is provided with a fourth elastic plate 551, which is bent and protrudes toward the receiving cavity 51 and is used to abut against the insulating seat 40.

[0067] With the above-mentioned structural design, the insulating base 40 can have a certain elastic margin in the first direction X and the second direction Y when connected to the housing 50, which facilitates the connection and disassembly of the insulating base 40 and the housing 50. In addition, the above-mentioned structural design also helps to fine-tune the contacts on the circuit board 200 of the first grounding terminal assembly 10, the second grounding terminal assembly 20 and the high-speed signal terminal assembly 30 on the insulating base 40 to ensure good contact.

[0068] In some embodiments, the side wall of the insulating base 40 is provided with a plurality of insertion slots, and the insertion slots are provided one-to-one with the elastic plates described above. When the insulating base 40 is connected to the housing 50 in the third direction Z, the elastic plates are inserted into the insertion slots.

[0069] In some embodiments, the insulating base 40 is a plastic base, and the housing 50 is a metal housing 50.

[0070] In some embodiments, please refer to Figure 1 and Figure 3 The housing 50 has a first latching part 56 on the top of the third direction Z. The first latching part 56 protrudes into the receiving cavity 51 and is used to connect with the external chip holder 300 to limit the chip holder 300 in the third direction Z.

[0071] As an example, a chip is disposed on a chip holder 300, and the chip holder 300 is provided with a second snap-fit ​​portion, wherein the first snap-fit ​​portion 56 and the second snap-fit ​​portion can be snapped together. During assembly, the housing 50 can be soldered and fixed to the circuit board 200 first. After assembling the terminal structures such as the first ground terminal assembly 10, the second ground terminal assembly 20, and the high-speed signal terminal assembly 30 with the insulating base 40, the insulating base 40 and the housing 50 are assembled and fixed in the third direction Z. Then, the chip holder 300 containing the chip is connected to the housing 50 in the third direction Z. The first snap-fit ​​portion 56 at the top of the housing 50 is stretched open and undergoes elastic deformation until the first snap-fit ​​portion 56 and the second snap-fit ​​portion are fastened together. The first snap-fit ​​portion 56 returns to its original deformation to fasten and fix the chip holder 300 in the third direction Z. This allows the contacts on the chip and the contacts on the circuit board 200 to contact the terminal structures such as the first ground terminal assembly 10, the second ground terminal assembly 20, and the high-speed signal terminal assembly 30, thereby realizing signal transmission between the chip and the circuit board 200.

[0072] This application also provides an electronic device, which includes the electrical connector 100 described above. For the specific structure and function of the electrical connector 100, please refer to any of the above embodiments; further details will not be provided here.

[0073] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
