[0042] Embodiments of the present application provide an electrical connector structure for connecting an optoelectronic transceiver module on a main board. In some embodiments, the optoelectronic transceiver module is an optoelectronic integrated circuit (OEIC) integrating an electronic integrated circuit and a photonic integrated circuit, and a co-packaged optics (CPO) transceiver module is formed using co-packaging technology. Preferably, the optoelectronic transceiver module may include at least one optical detection component and a light source module, as well as a plurality of active components and passive components, such as but not limited to filters or multiplexing structures, optical power distribution structures, fiber optic input / output structures, and optical modulation structures.

[0043] Referring to Figure 1 and Figure 2 , Figure 1 FIG. is a perspective combined schematic diagram of the electrical connector structure 1 of an embodiment of the present application and a main board 5, Figure 2 is Figure 1 an exploded schematic diagram of the electrical connector structure 1. As Figure 1 shown, the present application provides an electrical connector structure 1, including an interposer module 10 and a fixing structure 20. Specifically, the interposer module 10 includes a first board body 11 and a second board body 12 that can be assembled and disassembled with each other, and a plurality of terminal modules 13. Specifically, the second board body 12 and the first board body 11 are assembled in a stacked manner. The plurality of terminal modules 13 are disposed between the first board body 11 and the second board body 12, and each terminal module 13 includes a terminal seat 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 seat 130, and one end portion 134 of the first terminal arm 133 extends out of the first board body 11, and one end portion 136 of the second terminal arm 135 extends out of the second board body 12.

[0044] Continuing to refer to Figure 1, the fixing structure 20 includes a pair of fixing walls 201 and 202, a front limiting wall 203 and a rear limiting wall 204, a plurality of first limiting members 211 and a second limiting member 221. Specifically, the front limiting wall 203 and the rear limiting wall 204 are respectively connected between the front end and the rear end of the pair of fixing walls 201 and 202, and together with the pair of fixing walls 201 and 202 form a frame structure, and can be fixed on the surface 51 of a main board 5 through, for example, surface adhesion technology, thereby forming an accommodating space 200. In this embodiment, the main board 5 is a kind of circuit board, on which one or more processors and electronic components (not shown) can be provided, and is applicable to the main board of, for example, a switch or a server. In some embodiments, the fixing walls 201 and 202, the front limiting wall 203 and the rear limiting wall 204 can be made of materials with high hardness characteristics, such as metal materials, preferably stainless steel, and can be formed by a metal stamping process, but the above materials and preparation methods are not limited thereto. As Figure 1 and Figure 2 shown, by performing a stamping process on the fixing walls 201 and 202 to integrally form a plurality of first limiting members 211, the plurality of first limiting members 211 protrude into the accommodating space 200 and form an inclined side 211a and a free end 211b, so that the first limiting members 211 can be displaced outward due to the pressing of an external object in the accommodating space 200. In this embodiment, as Figure 2 shown, the fixing walls 201 and 202 include a plurality of fixing pieces 207 and limiting grooves 208. Specifically, the limiting grooves 208 are formed at a top edge 201a of the pair of fixing walls 201 and 202, and the fixing pieces 207 are arranged at a bottom 201b of the pair of fixing walls 201 and 202 and are respectively bent into the accommodating space 200. In this embodiment, the fixing pieces 207 can be fixed on the surface 51 of the main board 5 through surface adhesion technology.

[0045] As Figure 1 and Figure 2 shown, the intermediate board module 10 is detachably arranged on the main board 5. Specifically, the intermediate board module 10 enters the accommodating space 200 from directly above the accommodating space 200, and during the downward movement, it interferes with and presses the inclined sides 211a of the first limiting members 211 on the opposite two sides, thereby pushing the first limiting members 211 to displace outward. Finally, after passing through the first limiting members 211, the first limiting members 211 return to their original positions and their free ends 211a press and fix on the surface 51 of the main board 5. Through the above crimping method, the intermediate board module 10 can be firmly fixed on the main board 5, and the first terminal arm 133 contacts the corresponding conductive contacts (not shown) of the main board 5. When the intermediate board module 10 needs to be detached from the fixing structure 20, the first limiting members 211 can be pushed outward of the accommodating space 200 to take out the intermediate board module 10.

[0046] It should be noted that, in some other embodiments, the fixing structure 20 may also only have the pair of fixing walls 201 and 202 without the front limiting wall 203 and the rear limiting wall 204. The fixing walls 201 and 202 can utilize a diagonal bracing structure (not shown) supported on the main board 5 to strengthen the structural strength. In some other embodiments, the fixing walls 201 and 202 can also adopt a plurality of columnar structures (not shown). By the above settings of the fixing walls 201 and 202, the first limiting member 211 can also be used to press and fix the intermediate board module 10.

[0047] As Figure 2 shown, the rear limiting wall 204 includes a pivoting portion 206 having a shaft hole, and the second limiting member 221 is pivotally connected to the pivoting portion 206 and is disposed above the first limiting member 211. Specifically, the front limiting wall 203 includes an opening 203a and a pair of holding portions 205, and the holding portions 205 are disposed at a top of the front limiting wall 203 and on both sides of the opening 203a. In some embodiments, the pair of holding portions 205 respectively have a barb structure. As Figure 2 shown, 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. The pressing rods 223 and 224 and the connecting rod 222 are integrally formed to form a U-shaped structure, and the material of the second limiting member 221 can be the same as that of the fixing walls 201 and 202. Specifically, the connecting rod 222 is pivotally connected to the pivoting portion 206 and rotates about the pivoting portion 206 as the axis, thereby driving the pressing rods 223 and 224 to rotate between an open state (as Figure 2 shown) and a holding state (as Figure 12A shown) to press the optical transceiver module 3 or release the pressing on the optical transceiver module 3 (details will be described later). In some embodiments, the pressing rods 223 and 224 extend close to the fixing walls 201 and 202. Each of the pressing rods 223 and 224 includes an operating portion 225, which extends out of the holding portion 205 by a preset distance and bends upward to facilitate operating 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 can be movably held in the holding portions 205 of the barb structure.

[0048] Referring to Figure 3 , Figure 3 is a three-dimensional exploded view of the intermediate board module 10 according to an embodiment of the present application. As Figure 3As shown, the first plate body 11 includes a plurality of terminal slots 111 and a plurality of first positioning grooves 112, and the plurality of terminal slots 111 penetrate through an upper surface 11a and a lower surface 11b of the first plate body 11 in a thickness direction. Specifically, each terminal slot 111 extends in a short-axis direction of the first plate body 11, and the plurality of terminal slots 111 are arranged at intervals in a long-axis direction of the first plate body 11. The second plate body 12 is detachably assembled to the first plate body 11 and includes a pair of side walls 122 and 123 and a plurality of through slots 121, and the plurality of through slots 121 are arranged corresponding to the terminal slots 111 and communicate with the terminal slots 111.

[0049] As Figure 3 shown, the pair of side walls 122 and 123 are spaced apart from each other on a top portion 12a of the second plate body 12, and are 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 plurality of second positioning grooves 124 are respectively arranged at a top of the side walls 122 and 123. In this embodiment, the first limiting member 211 presses against the corresponding second positioning groove 124 (as Figure 1 shown) to fix the intermediate board module 10 to the main board 5. In addition, the fixing pieces 207 of the fixing walls 201 and 202 are inserted into the corresponding first positioning grooves 112 to further limit the first plate body 11 in the long-axis direction. As Figure 2 and Figure 3 shown, the terminal seat 130 of the terminal module 13 is arranged in the terminal slot 111 and is located between the first plate body 11 and the second plate body 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.

[0050] Continuing to refer to Figures 2 to 3 , in some embodiments, the first plate body 11 includes a plurality of first engaging portions 115, the second plate body 12 includes a plurality of first engaging members 125, and the first engaging members 125 are detachably engaged with the first engaging portions 115. Preferably, the first engaging member 125 is a downwardly protruding hook, and the first engaging portion 115 is a groove for the hook to be buckled. A bottom portion 12b of the second plate body 12 is attached to the upper surface 11a of the first plate body 11, and the bottom portion 12b of the second plate body 12 includes a plurality of positioning posts 126, and the positioning posts 126 extend in the direction of the first plate body 11. The first plate body 11 further includes a plurality of through holes 110, and the main board 5 includes a plurality of positioning holes 510, and the plurality of positioning posts 126 respectively penetrate through the plurality of through holes 110 and are inserted into the plurality of positioning holes 510 to further position the intermediate board module 10 on the main board 5.

[0051] Referring to Figure 4 and Figure 5 , Figure 4 is a schematic diagram of the manufacturing process of the terminal module 13 andFigure 5 It is a partial enlarged schematic diagram of the terminal module 13. In the embodiment of the present application, the terminal 131 is formed by a stamping process using a metal strip to form an integrally molded terminal structure. After stamping out the contour of the terminal 131, the terminal seat 130 is formed on the row of terminals 131 by using the insert injection molding technology. Then, the metal strip is cut to directly obtain the terminal seat 130 combined with the row of terminals 131, that is, the production of the terminal module 13 is completed. It should be noted that since the interposer module 10 of the present application is configured with thousands of terminals 131, and each terminal 131 is a micro-size in millimeters, the assembly difficulty between the terminal and the terminal seat is greatly increased. By directly forming the terminal 131 integrally on the continuous metal strip through the above stamping process, and then using the insert injection molding technology to combine the terminal 131 with the terminal seat 130, the terminal 131 can be accurately and firmly fixed on the terminal seat 130, effectively reducing the assembly difficulty and being more beneficial to the subsequent combination of the terminal module 13 and the terminal slot 111.

[0052] Continue to refer to Figure 4 and Figure 5 and cooperate with Figure 3 , the first terminal arm 133 inclines from the root 132 toward the middle of the terminal slot 111 of the first plate body 11 and the accommodation space 200, and the second terminal arm 135 inclines from the root 132 toward the middle of the through slot 121 of the second plate body 12 and 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 132. In this embodiment, the second terminal arm 135 has a convex arc-shaped cross section relative to the terminal seat 130, which extends from the root 132 to the end 136 of the second terminal arm 135, and the first terminal arm 133 has an arc-shaped cross section identical to that of the second terminal arm 135. The terminal seat 130 covers the root 132, and a plurality of terminals 131 are aligned in a row and arranged at intervals from each other on the terminal seat 130. In some embodiments, the ends 134 and 136 have convex arc-shaped profiles to facilitate contact with the conductive contacts for docking. It should be specifically noted that the second terminal arm 135 and the first terminal arm 133 can be deformed by the external object pressing and can return to their original states when the pressure is released.

In some embodiments, the connector head 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. Specifically, the limiting protrusions 308 are provided on the opposite sides 301 and 302 of the optical transceiver module 3. After the intermediate board module 10 enters the accommodation space 200 through a crimping method and is fixed on the main board 5, the protective cover plate 15 is removed, and the optical transceiver module 3 is detachably disposed on the intermediate board module 10 through a crimping method, wherein the limiting protrusions 308 are detachably engaged with the limiting grooves 208 of the fixing walls 201 and 202 (as Figure 7 shown).

[0054] As Figure 9 and Figure 10 shown, after the optical transceiver module 3 is positioned by crimping, the pressing rods 223 and 224 of the second limiting member 221 press against the top 30a of the optical transceiver module 3, and the bottom of the optical transceiver module 3 is located within the fixing walls 201 and 202, and the optical transceiver module 3 is electrically connected to the main board 5 through the plurality of terminals 131 of the intermediate board module 10.

Figure 13 As shown, when the optoelectronic transceiver module 3 is pressed downward onto the second plate 12, the 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.

[0057] Reference Figure 14 , which is a schematic diagram of a use state of the electrical connector structure 1 according to an embodiment of the present application. Figure 14 As shown, the middle part of the motherboard 5 may be provided with electronic components such as a processor (not shown), and multiple sets of electrical connector structures 1 and optoelectronic transceiver modules 3 may be respectively configured around the motherboard 5. The actual number of electrical connector structures 1 and optoelectronic transceiver modules 3 may be determined according to the needs and are 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 handle high-capacity signal transmission to meet the needs of high-speed and large-volume signal processing.

[0058] In summary, in the electrical connector structure of the embodiment of the present application, the intermediate board module and the optical transceiver module can be sequentially stacked in a crimping manner and detachably arranged in the fixing structure, and the first limiting member and the second limiting member are respectively used to firmly press the intermediate board module and the optical transceiver module, so that the optical transceiver module can be connected to the electrical connector structure through a simple crimping method. Furthermore, the main board is directly electrically connected through the integrally formed terminals of the intermediate board module, so that the electrical signals after optical-electrical conversion from the optical transceiver module can be transmitted to the main board, thereby giving full play to the advantages of high-capacity and high-speed transmission provided by the optical transceiver module, shortening the transmission distance between the optical transceiver module and the main board, and facilitating maintenance and replacement, effectively solving the problem that the co-packaged optical components in the prior art need to be connected to the main board through connecting wires and connectors, resulting in too long transmission paths and difficult maintenance and replacement.
