In some embodiments, the optoelectronic transceiver module connected by the electrical connector structure of the present application has an architecture that complies with the 3.2 Tb/s co-packaged module implementation protocol specified by the Optical Internetworking Forum (OIF).
Referring to FIGS. 1 and 2, FIG. 1 is a schematic perspective assembly of an electrical connector structure 1 and a mainboard 5 according to an embodiment of the present application, and FIG. 2 is a schematic exploded view of the electrical connector structure of FIG. 1. As shown in FIG. 1, the present application provides the electrical connector structure 1, including an interposer module 10 and a fixing structure 20. In detail, the interposer module 10 includes a first board 11 and a second board 12 that can be assembled and detached from each other, and a plurality of terminal modules 13. Specifically, the second board 12 and the first board 11 are assembled in an up-and-down stacking manner. A plurality of terminal modules 13 are disposed between the first board 11 and the second board 12, and each terminal module 13 includes a terminal base 130 and a plurality of terminals 131. In some embodiments, each terminal 131 includes a root portion 132, a first terminal arm 133, and a second terminal arm 135. The root portion 132 is fixed to the terminal base 130, and an end 134 of the first terminal arm 133 extends out of the first board 11, and an end 136 of the second terminal arm 135 extends out of the second board 12.
Still referring to FIG. 1, the fixing structure 20 includes a pair of fixing walls 201 and 202, a front limiting wall 203, a rear limiting wall 204, a plurality of first limiting members 211, and a second limiting member 221. In detail, the front limiting wall 203 and the rear limiting wall 204 are connected between the front end and the rear end of the pair of fixing walls 201 and 202, and form a frame structure together with the pair of fixing walls 201 and 202, and can be fixed on a surface 51 of the mainboard 5 by, for example, surface adhesive technology, thereby forming an accommodation space 200. In this embodiment, the mainboard 5 is a circuit board on which one or more processors and electronic components (not shown) may be disposed, and is suitable for being a mainboard of a switch or a server, for example. In some embodiments, the fixing walls 201 and 202, the front limiting wall 203 and the rear limiting wall 204 can be made of a material with high hardness characteristics, such as metal, preferably stainless steel, and can be formed by a metal stamping process, but the above materials and fabrication methods are not limited thereto. As shown in FIGS. 1 and 2, the first limiting members 211 are integrally formed by stamping the fixing walls 201 and 202. Each of the first limiting members 211 protrudes toward the accommodation space 200 and forms a bevel 211a and a free end 211b, so that the first limiting members 211 can be displaced outward due to the pressing of external objects in the accommodation space 200. In this embodiment, as shown in FIG. 2, the fixing walls 201 and 202 include a plurality of fixing plates 207 and limiting grooves 208. Specifically, the limiting grooves 208 are formed at a top edge of the pair of fixing walls 201 and 202, and the fixing plates 207 are disposed at a bottom 201b of the pair of fixing walls 201 and 202 and are bent toward the accommodation space 200. In this embodiment, the fixing plates 207 can be fixed on the surface 51 of the mainboard 5 by using surface mounting technology.
As shown in FIG. 1 and FIG. 2, the interposer module 10 is detachably disposed on the mainboard 5. In detail, the interposer module 10 enters the accommodation space 200 downward from the top of the accommodation space 200 and interferes with and presses the bevels 211a of the first limiting members 211 on the two opposite sides of the accommodation space 200 during the downward movement, thereby pushing the first limiting members 211 to move outward. Finally, after the interposer module 10 passes the first limiting members 211, the first limiting members 211 return to their original position, and the free ends of the first limiting members 211 are pressed and fixed on the surface 51 of the mainboard 5. Through the above-mentioned press-connection method, the interposer module 10 can be firmly fixed on the mainboard 5, and the first terminal arm 133 contacts a corresponding conductive contact (not shown) of the mainboard 5. When the interposer module 10 is to be detached from the fixing structure 20, the first limiting members 211 can be pushed outwards of the accommodation space 200 to remove the interposer module 10.
It should be noted that in some other embodiments, the fixing structure 20 may only have the pair of fixing walls 201 and 202 without the front limiting wall 203 and the rear limiting wall 204. In some embodiments, the fixing walls 201 and 202 may utilize a diagonal bracing structure (not shown) supported on the mainboard 5 to enhance the structural strength. In some other embodiments, the fixing walls 201 and 202 may also be formed of a plurality of columnar structures (not shown). By the disposition of the fixing walls 201 and 202, the first limiting members 211 may also be used to press and fix the interposer module 10.
As shown in FIG. 2, the rear limiting wall 204 includes a pivot portion 206 having an axis hole, and the second limiting member 221 is pivotally connected to the pivot portion 206 and is disposed above the first limiting members 211. In detail, the front limiting wall 203 includes an opening 203a and a pair of retaining portions 205. The retaining portions 205 are disposed at a top of the front limiting wall 203 and located at two sides of the opening 203a. In some embodiments, the pair of retaining portions 205 each have a hook structure. As shown in FIG. 2, the second limiting member 221 includes a pair of pressing rods 223 and 224 and a connecting rod 222 connected between the pair of pressing rods 223 and 224. The pressing rods 223 and 224 are integrally formed with the connecting rod 222 to form a U-shaped structure, and the material of the second limiting member 221 may be the same as that of the fixing walls 201 and 202. In detail, the connecting rod 222 is pivotally connected to the pivot portion 206 and rotates around the pivot portion 206, thereby causing the pressing rods 223 and 224 to rotate in an open state (as shown in FIG. 2) or in a holding state (as shown in FIG. 12A) to press the optoelectronic transceiver module 3 or release the pressing force on the optoelectronic transceiver module 3 (as described later in detail). In some embodiments, the pressing rods 223 and 224 are configured to extend to the fixing walls 201 and 202, and each of the pressing rods 223 and 224 includes a manipulating portion 225, which extends out of the retaining portion 205 by a preset distance and is bent upward to facilitate the rotation of the pressing rods 223 and 224 between the open state and the holding state. When the pressing rods 223 and 224 are in the holding state, the ends of the pressing rods 223 and 224 away from the connecting rod 222 are movably held on the retaining portion 205 of the hook structure.
Referring to FIG. 3, FIG. 3 is a schematic perspective exploded view of the interposer module 10 according to an embodiment of the present application. As shown in FIG. 3, the first board 11 includes a plurality of terminal slots 111 and a plurality of first positioning grooves 112, and the plurality of terminal slots 111 pass through an upper surface 11a and a lower surface 11b of the first board 11 in a thickness direction. In detail, each terminal slot 111 extends in a short axis direction of the first board 11, and the terminal slots 111 are arranged at intervals in a long axis direction of the first board 11. The second board 12 is detachably assembled to the first board 11 and includes a pair of side walls 122 and 123 and a plurality of through slots 121. The plurality of through slots 121 are disposed corresponding to the terminal slots 111 and communicate with the terminal slots 111.
As shown in FIG. 3, the pair of side walls 122 and 123 are disposed at a top portion 12a of the second board 12 and are spaced apart from each other. The side walls 122 and 123 are located close to and parallel to the fixing walls 201 and 202, and each of the side walls 122 and 123 includes a plurality of second positioning grooves 124. The second positioning grooves 124 are disposed on a top of the side walls 122 and 123, respectively. In this embodiment, the first limiting members 211 press against the second positioning grooves 124, respectively, to fix the interposer module 10 on the mainboard 5 (as shown in FIG. 1). In addition, the fixing plates 207 of the fixing walls 201 and 202 are inserted into the corresponding first positioning grooves 112 to further limit the first board 11 in the longitudinal direction. As shown in FIGS. 2 and 3, the terminal base 130 of the terminal module 13 is disposed in the terminal slot 111 and located between the first board 11 and the second board 12, and the end 134 of the first terminal arm 133 extends out of the terminal slot 111, and the end 136 of the second terminal arm 135 extends out of the through slot 121.
Still referring to FIGS. 2 and 3, in some embodiments, the first board 11 includes a plurality of first fastening portions 115, the second board 12 includes a plurality of first fastening elements 125, and the first fastening elements 125 are detachably fastened with the first fastening portions 115. Preferably, each of the first fastening elements 125 is a hook protruding downward, and the first fastening portion 115 is a groove for the hook to be engaged. A bottom 12b of the second board 12 is attached to the upper surface 11a of the first board 11. The bottom 12b of the second board 12 includes a plurality of positioning posts 126 extending toward the first board 11. The first board 11 further includes a plurality of through holes 110, the mainboard 5 includes a plurality of positioning holes 510, and the positioning posts 126 pass through the through holes 110 and are inserted into the positioning holes 510, respectively, to further position the interposer module 10 on the mainboard 5.
Referring to FIGS. 4 and 5, FIG. 4 is a flowchart of a manufacturing process of the terminal module 13, and FIG. 5 is a partially enlarged schematic view of the terminal module 13. The terminals 131 of the embodiment of the present application are fabricated by stamping a metal strip to form an integrally formed terminal structure. After the outline of the terminals 131 is stamped out, the terminal base 130 is formed on a row of terminals 131 through the insert molding process, and then the metal strip is cut to directly obtain the terminal base 130 combined with the row of terminals 131, thereby completing the formation of the terminal module 13. It should be noted that, since the interposer module 10 of the present application is configured with thousands of the terminals 131, and each terminal 131 is of a millimeter-level micro size, the difficulty of assembling the terminals and the terminal bases is greatly increased. The terminals 131 are directly integrally formed on the continuous metal strip through the above-mentioned stamping process, and then the terminals 131 are combined with the terminal base 130 using the insert molding process. The terminals 131 can be accurately and firmly fixed to the terminal base 130, effectively reducing the difficulty of assembly and being more conducive to the subsequent combination of the terminal module 13 and the terminal slot 111.
Still referring to FIGS. 4 and 5 in combination with FIG. 3, the first terminal arm 133 is inclined from the root portion 132 toward the terminal slot 111 of the first board 11 and a middle of the accommodation space 200, and the second terminal arm 135 is inclined from the root portion 132 toward the through slot 121 of the second board 12 and a middle of the accommodation space 200, and the first terminal arm 133 and the second terminal arm 135 are symmetrically arranged up and down relative to the root portion 132. In this embodiment, the second terminal arm 135 has an outwardly convex arc-shaped section with respect to the terminal base 130.

The first terminal arm 133 has an arc-shaped section that is the same as the arc-shaped section of the second terminal arm 135. The terminal base 130 covers the root portion 132, and the plurality of terminals 131 are aligned in a row and spaced apart from each other on the terminal base 130. In some embodiments, the ends 134 and 136 have a convex arc profile to facilitate contact with mating conductive contacts. It is noted that the second terminal arm 135 and the first terminal arm 133 can be deformed by a pressing force from an external object and can return to their original shape when the pressing force is released.

As shown in FIG. 6, the electrical connector structure 1 of the embodiment of the present application further includes a protective cover 15, which is removably covered on the top 12a of the second board 12 to protect the exposed terminals 131 during the assembly process. In some embodiments, as shown in FIG. 6, the optoelectronic transceiver module 3 includes a top portion 30a, two opposite sides 301 and 302, a neck portion 303, a joint portion 304, and a plurality of engaging protrusions 308. In some embodiments, the joint portion 304 is used to connect a plurality of optical fibers (not shown) or cables (not shown) to transmit and receive optical signals or electrical signals. In detail, the engaging protrusions 308 are disposed on two opposite sides 301 and 302 of the optoelectronic transceiver module 3. After the interposer module 10 enters the accommodation space 200 and is fixed on the mainboard 5 by press-connection, the protective cover 15 is removed, and the optoelectronic transceiver module 3 is detachably disposed on the interposer module 10 by press-connection. At this time, the engaging protrusions 308 are detachably engaged with the limiting grooves 208 of the fixing walls 201 and 202 (as shown in FIG. 7).
As shown in FIGS. 9 and 10, after the optoelectronic transceiver module 3 is positioned through press-connection, the pressing rods 223 and 224 of the second limiting member 221 press against the top 30a of the optoelectronic transceiver module 3, and the bottom of the optoelectronic transceiver module 3 is located within the fixing walls 201 and 202, so that the optoelectronic transceiver module 3 is electrically connected to the mainboard 5 through the terminals 131 of the interposer module 10. As shown in FIG. 11, the bottom of the optoelectronic transceiver module 3 includes a positioning protrusion 305, and the interposer module 10 includes a hollow portion 105 (as shown in FIG. 2). The positioning protrusion 305 is inserted into the hollow portion 105 to further position the optoelectronic transceiver module 3 and the interposer module 10 on the mainboard 5.
Referring to FIGS. 12A to 12F, FIGS. 12A to 12F are schematic views showing a process of connecting the optoelectronic transceiver module 3 to the electrical connector structure 1 through press-connection. During connection, the fixing structure 20 is first assembled at a predetermined position of the mainboard 5 (as shown in FIG. 12A), and then the second limiting member 221 is opened to the open state (as shown in FIG. 12B). Next, the protective cover 15 is used to press the interposer module 10 from the top of the mainboard 5 downward to the accommodation space 200, so that the interposer module 10 is pressed against the surface 51 of the mainboard 5 through the first limiting members 211 (as shown in FIG. 12C). After the interposer module 10 is positioned, the protective cover 15 is removed (as shown in FIG. 12D). The optoelectronic transceiver module 3 is placed from top to bottom in the accommodation space 200 until the limiting protrusions 308 are engaged with the limiting grooves 208 (as shown in FIG. 12E).

Similarly, when the optoelectronic transceiver module 3 is to be taken out, the second limiting member 221 is opened to the open state through the manner opposite to the above steps to take out the optoelectronic transceiver module 3.
Referring to FIG. 13, FIG. 13 is a schematic structural view showing the contact between the terminals 131 and the optoelectronic transceiver module 3. As shown in FIG. 13, when the optoelectronic transceiver module 3 is pressed downward onto the second board 12, a conductive contact (not shown) at the bottom of the optoelectronic transceiver module 3 contacts the end 136 of the second terminal arm 135 and forces the second terminal arm 135 to move downward, so that each terminal 131 can be securely connected to the corresponding conductive contact.
Referring to FIG. 14, it is a schematic view showing a usage state of the electrical connector structure 1 according to an embodiment of the present application. As shown in FIG. 14, a middle part of the mainboard 5 can be provided with electronic components such as a processor (not shown in the figures), and multiple sets of the electrical connector structures 1 and optoelectronic transceiver modules 3 can be configured around the mainboard 5, respectively. The actual number of sets of the electrical connector structures 1 and optoelectronic transceiver modules 3 is determined according to needs and is not particularly limited. Each optoelectronic transceiver module 3 is externally connected to a signal transmission component, such as an optical fiber or a cable (not shown). The above structure can be used to process high-capacity signal transmission and reception to meet the needs of high-speed and large-volume signal processing.
Accordingly, in the embodiments of the present application, the interposer module and the optoelectronic transceiver module of the electrical connector structure can be stacked in sequence by press-connection and detachably arranged in the fixing structure, and the first limiting members and the second limiting member are used to firmly press the interposer module and the optoelectronic transceiver module, respectively, so that the optoelectronic transceiver module can be installed to the electrical connector structure by simple press-connection, which in turn is directly electrically connected to the mainboard through the integrally formed terminal of the interposer module, so that the electrical signal from the optoelectronic transceiver module after photoelectric conversion can be transmitted to the mainboard, so as to fulfill the advantages of high capacity and high-speed transmission provided by the optoelectronic transceiver module, and shorten the transmission distance between the optoelectronic transceiver module and the mainboard, thereby effectively solving the problem that current co-packaged optical transceiver components must be connected to mainboards by cables and additional connectors, resulting in relatively longer transmission paths and difficult maintenance and replacement.
