Please refer to Figures 1 to 19. The present design discloses a high-speed connector module 100, including a connector component 1, a metal cover 2 covering the periphery of the connector component 1, a metal base plate 3 covering the lower surface of the connector component 1, and a heat dissipation module 4 assembled on the metal cover 2. In the present design, the one high-speed connector module 100 includes two connector components 1 arranged in parallel along the left-right direction, the two connector components 1 share a metal cover 2 (see Figures 3 to 5), and the one metal cover 2 is partitioned into two corresponding spaces. Of course, in other embodiments, the one high-speed connector module 100 may also be provided with only one connector component 1, and the size of the corresponding metal cover 2 may be adapted to be changed and only one corresponding space may be formed.

Please refer to Figures 6 to 12. In this design, the connector assembly 1 is actually a socket connector, including an insulating body 10, a first terminal module 11, a second terminal module 12, a third terminal module 13, a rear seat body 14 located at the rear end of the insulating body 10, an injection molded part 15 and a grounding part 114. The first terminal module 11, the second terminal module 12 and the third terminal module 13 are fixed to the insulating body 10 by assembly. In the left and right direction, the third terminal module 13 is located between the first terminal module 11 and the second terminal module 12. The rear seat body 14 is made of metal material, and in this design, it is specifically made by powder metallurgy process. The injection molded part 15 is formed by injection molding of hot-melt insulating material.

Please refer to Figures 6 to 12, the insulating body 10 is formed by injection molding of a hot-melt insulating material, and includes a roughly rectangular tubular plug-in portion 101 located at the front end and a mounting portion 102 located at the rear end of the plug-in portion 101. A plug-in space (not numbered) for accommodating a docking connector (not shown) is formed in the middle of the plug-in portion 101, and a plug-in interface 1010 is formed at the front end. The cross-sectional profile of the mounting portion 102 along a direction perpendicular to the front and rear directions is larger than that of the plug-in portion 101. A mating space 1021 is formed in the middle of the mounting portion 102. The front end of the mating space 1021 is connected to the plug-in space, and the rear end of the mating space 1021 passes through the rear end surface of the mounting portion 102. A clearance opening 1025 is formed on the lower surface of the mounting portion 102 near the rear end, and the clearance opening 1025 is connected to the mating space 1021. The upper surface of the rear end of the mounting portion 102 is recessed downward to form a matching groove 1022 . The matching groove 1022 is generally formed in the form of a dovetail groove that gradually narrows from front to back and has an open shape toward the rear end.

Please refer to Figures 6 to 10. The rear seat body 14 includes a plate-shaped main body plate 141, an upper side plate 142 formed by horizontally extending forward from the upper side edge of the front end surface of the main body plate 141, and two limit parts 143 formed by extending forward from the lower side edge of the front end surface of the main body plate 141. The two limit parts 143 are located at the left and right sides of the lower side edge of the main body plate 141. The upper side plate 142 is formed with a corresponding groove 1421 at a position corresponding to the matching groove 1022 in the up and down direction. In this design, the cross section of the corresponding groove 1421 along the surface perpendicular to the up and down direction is larger than the cross section of the matching groove 1022, and the corresponding groove 1421 forms a step-like structure with the outer contour position of the matching groove 1022 (see Figure 7). The limit part 143 corresponds to the rear end position of the insulating body 10 and is fixed, and specifically cooperates with the fixed groove 1023 (see Figure 10) formed at the corresponding position of the rear end of the insulating body 10. Each of the limiting parts 143 is formed with a clearance groove 1431 along the up-down direction, and the clearance groove 1431 penetrates the limiting part 143 toward the front end. The main body plate 141 is formed with eight cable holes 1411 along the front-back direction for the cables 5 to pass through (see FIG. 10 ). The grounding member 114 is partially embedded in the clearance groove 1431 to achieve limiting and overlapping with the rear seat body 14 (specifically, the connection plate 1142 of the grounding member 114 described below partially extends into the clearance groove 1431).

In this design, the rear seat body 14 is assembled and fixed with the insulating body 10 from the back to the front, the upper side plate 142 covers the upper surface of the mounting portion 102, and a matching gap 1422 is formed between the rear seat body 14 and the insulating body 10 (the matching gap 1422 is specifically formed between the inner mold and the main plate 141 described below), and the matching gap 1422 is connected with the matching groove 1022 and the corresponding groove 1421. The hot melt plastic is injected into the matching gap 1422, the matching groove 1022 and the corresponding groove 1421 to form the injection molded part 15, and the injection molded part 15 includes a fixed protrusion 151 (see Figure 8) that fills the matching groove 1022 and the corresponding groove 1421 and has a stepped outer surface. The injection molded part 15 is used to make the rear seat body 14 and the insulating body 10 more tightly combined. The step-shaped structure design formed by the corresponding groove 1421 and the matching groove 1022 and the dovetail structure design of the matching groove 1022 are both for making the insulating body 10, the rear seat body 14 and the injection molded part 15 tightly connected.

Please refer to Figures 11 to 16, the first terminal module 11 and the second terminal module 12 have roughly the same structure. Taking the first terminal module 11 as an example, the first terminal module 11 includes a conductive plate 111 that is roughly plate-shaped and has conductive properties, an upper grounding plate 1121 and a lower grounding plate 1122 that are attached to the upper and lower surfaces of the conductive plate 111, an upper high-speed terminal assembly 1131 that is attached to the upper surface of the upper grounding plate 1121, a lower high-speed terminal assembly 1132 that is attached to the lower surface of the lower grounding plate 1122, and a grounding piece 114 clamped between the rear ends of the upper grounding plate 1121 and the lower grounding plate 1122. In this design, the conductive plate 111 is formed of conductive plastic.

The upper high-speed terminal assembly 1131 includes seven upper high-speed terminals 1151 arranged in a row, an upper insulating member 1161 fixed to the middle position of the upper high-speed terminals 1151 by injection molding, a cable 5 connected to the rear end of each upper high-speed terminal 1151, and an upper inner mold 1171 fixed to the rear end of the upper high-speed terminal 1151 by injection molding. The lower high-speed terminal assembly 1132 includes seven lower high-speed terminals 1152 arranged in a row, a lower insulating member 1162 fixed to the middle position of the lower high-speed terminals 1152 by injection molding, a cable 5 connected to the rear end of each lower high-speed terminal 1152, and a lower inner mold 1172 fixed to the rear end of the lower high-speed terminal 1152 by injection molding.

Please refer to FIG. 15 in combination with FIG. 11 and FIG. 12 , a row of upper high-speed terminals 1151 of the first terminal module 11 and a corresponding row of lower high-speed terminals 1152 are staggered in the left-right direction, and the row of upper high-speed terminals 1151 is biased toward the side where the insulating portion is located. Each upper high-speed terminal 1151 and the lower high-speed terminal 1152 are staggered one by one along the left-right direction. Each row of upper high-speed terminals 1151 and each row of lower high-speed terminals 1152 respectively include two pairs of high-speed differential terminals A and three grounding terminals B spaced apart from each pair of high-speed differential terminals. Each of the upper high-speed terminals 1151 and the lower high-speed terminals 1152 includes a terminal fixing portion 1101 fixed in the corresponding insulating parts 1161, 1162, a terminal contact portion 1102 protruding from the front end of the terminal fixing portion 1101 outside the corresponding insulating parts 1161, 1162 and protruding into the insertion space, and a terminal docking portion 1103 protruding from the rear end of the terminal fixing portion 1101 outside the corresponding insulating parts 1161, 1162.

Please refer to FIG. 15 in combination with FIG. 12 . In this design, the upper high-speed terminals 1151 and the lower high-speed terminals 1152 in the same row are formed by stamping and bending a piece of metal plate (formed by bending the metal plate in the thickness direction in the up-down direction). The terminal docking parts 1103 of the upper high-speed terminals 1151 and the lower high-speed terminals 1152 in the same row are both arranged flush in the left-right direction, and the terminal docking parts 1103 of the grounding terminals B of the upper high-speed terminals 1151 and the lower high-speed terminals 1152 in the same row extend in the front-to-back direction. The length of the terminal docking parts 1103 of the high-speed differential terminals A can be ensured to be isolated and shielded by the grounding terminals B on both sides of the overall length of each pair of high-speed differential terminals A, so that the connector assembly 1 has better high-frequency characteristics and stronger anti-crosstalk capability. The rear ends of the terminal docking parts 1103 of each grounding terminal B of the same row of upper high-speed terminals 1151 or the same row of lower high-speed terminals 1152 are respectively bent toward the side where the conductive plate 111 is located and extend backward to form a lap board 1104 that connects the three grounding terminals B as a whole. The surface of one side of the lap board 1104 exposes the corresponding inner mold 1171, 1172 (see Figure 12) and overlaps with the corresponding grounding plates 1121, 1122 to achieve common grounding. Of course, in other embodiments, the lap boards 1104 of each grounding terminal B can also be designed to be independent of each other.

In this design, each terminal in the first terminal module 11 and the second terminal module 12 is connected to the corresponding cable 5, specifically, the terminal docking portion 1103 of each high-speed differential terminal A is welded and fixed to the signal line of the cable 5, and the terminal docking portion 1103 of each grounding terminal B is welded and fixed to the grounding line of the cable 5. It should be noted that in the connector assembly 1 of the high-speed connector module 100 in this design, the spacing between the terminal fixing portion 1101 of each upper high-speed terminal 1151 and the terminal fixing portion 1101 of each lower high-speed terminal 1152 in the same high-speed terminal module 11, 12 is required to be a specific value. Under the condition of ensuring that the spacing between the terminal fixing portions 1101 of the upper and lower terminals is minimized, the bending method of the lap plate 1104 in this design can make the corresponding cable 5 bear on the surface of the lap plate 1104, so that part of the thickness of the cable 5 can be absorbed by the position, so as to reduce the overall thickness of the connector assembly 1 in the up and down directions as much as possible. In addition, the bending shape of the lap plate 1104 is conducive to designing the high-speed differential terminal A to be shielded by the ground terminal B on both sides of the entire length in the front-to-back direction (that is, the high-speed differential terminal A overlaps the ground terminal B in the left-right direction over the entire length). In this way, the grounding shielding effect is better.

Please refer to Figures 10 to 16. The upper grounding sheet 1121 and the lower grounding sheet 1122 are exactly the same in shape and are formed by stamping and bending metal plates, including a flat main body sheet 1001, a plurality of elastic contact feet 1002 formed by stamping and bending the front end of the main body sheet 1001, and an elastic end sheet 1003 formed by bending the rear edge of the main body sheet 1001 toward the side where the conductive plate 111 is located and folding forward. The elastic contact foot 1002 is bent and extended from the main body sheet 1001 to the side away from the conductive plate 111 and is in an elastic cantilever structure. In this design, three rows of elastic contact feet 1002 arranged in the left and right directions are provided on the grounding sheet 1121, 1122, wherein each row of elastic contact feet 1002 is provided with three elastic contact feet 1002 spaced in the front and back directions, which correspond to elastic contact with the grounding terminal B respectively for grounding effect. Multiple and multiple rows of elastic contact feet 1002 are designed to ensure the contact stability between each grounding terminal B, and at the same time ensure that different parts of each grounding terminal B are in a zero potential state.

Please refer to Figures 12, 15 and 16. In this design, in the first terminal module 11 and the second terminal module 12, in the up and down directions, the area between the row of upper high-speed terminals 1151 or the row of lower high-speed terminals 1152 except the terminal contact portion 1102 is provided with grounding plates 1121 and 1122 (that is, the extension area of the grounding plates 1121 and 1122 exceeds the area between the corresponding row of upper high-speed terminals 1151 or the row of lower high-speed terminals 1152 except the terminal contact portion 1102). In this way, the grounding plates 1121 and 1122 can have a shielding function, further improving the high-frequency characteristics.

In this design, only one grounding plate 1121, 1122 may be provided in the first terminal module 11 and/or the second terminal module 12. In this embodiment, one of the grounding plates 1121, 1122 is bent to both sides to form a plurality of elastic contact pins 1002, which are in contact with the grounding terminal B in the upper high-speed terminal 1151 and the lower high-speed terminal 1152 to achieve the grounding effect. In other embodiments, the conductive plate 111 structure may even be eliminated. Only one grounding plate 1121, 1122 is required to contact the grounding terminal B in the upper high-speed terminal 1151 and the lower high-speed terminal 1152 to achieve the grounding effect.

Please refer to FIG. 10 to FIG. 16 , the grounding member 114 is made of a metal plate and is roughly L-shaped. It includes a contact plate 1141 corresponding to the elastic end piece 1003 clamped between the upper grounding plate 1121 and the elastic end piece 1003 of the lower grounding plate 1122, and a connecting plate 1142 connected to the contact plate 1141 and extending downward along one side in the left-right direction. The connecting plate 1142 further extends downward to form a plug pin 1143. In this design, the plug pin 1143 specifically extends downward from the two sides of the lower surface of the insulating body 10 to the outside of the entire connector assembly 1 for docking with the docking circuit board 6.

In the present design, the first terminal module 11 and the second terminal module 12 have substantially the same structure, which can be seen in detail in FIG. 11 to FIG. 14 , so the detailed structure of the second terminal module 12 will not be described in detail.

Please refer to Figures 10 to 16, the third terminal module 13 includes five third terminal components 131, each of which includes an insulating sheet 1311 and two non-high-speed terminals 130 fixed in the insulating sheet 1311 by injection molding. Each non-high-speed terminal 130 is formed by blanking a metal plate (that is, each non-high-speed terminal 130 is formed by stamping a metal plate in the thickness direction of the left and right directions). Each non-high-speed terminal 130 is roughly L-shaped, including a terminal fixing portion 1301 correspondingly buried in the insulating sheet 1311, a cantilever-shaped terminal contact portion 1302 formed by extending forward from the front end of the terminal fixing end 1301, and a terminal docking portion 1303 connected to the rear end of the terminal fixing end 1301 and extending downward out of the insulating sheet 1311. The terminal docking portion 1303 is used to be inserted into the docking pin 61 of the docking circuit board 6. The terminal docking portion 1303 is preferably a fisheye pin structure (i.e., a fisheye terminal structure with an elliptical through hole in the middle), and the docking pin 61 of the docking circuit board is a through hole structure with a gold finger. Of course, in other embodiments, the terminal docking portion 1303 can also be designed in other forms, as long as the structures on both sides of the terminal docking portion 1303 can be elastically deformed toward the middle, that is, the terminal docking portion 1303 can effectively contact the inner wall of the docking pin 61 when inserted into the docking pin 61 of the circuit board 6.

Please refer to Figures 12 to 19. In this design, the five third terminal assemblies 131 are stacked and arranged in the left-right direction (specifically formed by stacking and limiting five insulating sheets 1311). The ten non-high-speed terminals 130 are arranged in two rows in the up-down direction. In the left-right direction, the terminal contact parts 1302 of the ten non-high-speed terminals 130 are staggered one by one (see Figure 19 for details), which are specifically formed by bending the terminal fixing ends 1301 of the five non-high-speed terminals 130 in the upper row or the five non-high-speed terminals 130 in the lower row along the left-right direction (specifically not shown). The two terminal docking parts 1303 of the third terminal assembly 131 are aligned in the front-to-back direction. The terminal docking part 1303 of the five non-high-speed terminals 130 in the upper row of the terminal contact part 1302 is located as a whole at the rear position of the terminal docking part 1303 of the five non-high-speed terminals 130 in the lower row of the terminal contact part 1302.

Please refer to Figures 17 to 19. The terminal mating parts 1303 of the five non-high-speed terminals 130 in the upper row and the five non-high-speed terminals 130 in the lower row are arranged in five rows in the left-right direction, and the terminal in the middle of the five non-high-speed terminals 130 in the upper row and the five non-high-speed terminals 130 in the lower row is the power terminal C, and the terminal mating parts 1303 of the four terminals of the five non-high-speed terminals 130 in the upper row and the five non-high-speed terminals 130 in the lower row, excluding the power terminal C, are arranged in four rows in the front-to-back direction.

When the two high-speed connector modules 100 in this design are plugged and assembled to the docking circuit board 6 along the upper and lower surfaces of the docking circuit board 6, among the non-high-speed terminals 130 of each high-speed connector module 100, only the terminal docking parts 1303 of the two opposite power terminals C share the docking pins 61 of the docking circuit board 6, and the terminal docking parts 1303 of other non-high-speed terminals 130 except the power terminals C do not share the docking pins 61. Such a design can simplify the structural design of the docking pins 61 of the docking circuit board, and only an ordinary circuit board is required to realize the function, and there is no need to specially process the docking pins 61 (here the special treatment refers to disconnecting the gold fingers on the upper and lower surfaces of the same docking pin 61) because the terminal docking parts 1303 of other non-high-speed terminals 130 except the power terminals C share the docking pins 61. This can save the cost of the docking circuit board. The power terminals C can be connected in series, and when the power terminals C share the docking pins 61, there is no need to do special processing on the docking pins 61. Such a design also makes the wiring of the docking circuit board 6 simpler and more reasonable. In this design, the ground terminals B are shared by a common ground and form a loop with the power terminal C in the non-high-speed terminal 130 .

Please refer to Figures 11 to 16, the five insulating sheets 1311 of the third terminal module 13 are assembled and stacked in the left and right directions to form an insulating part (not numbered). The terminal contact parts 1102 and 1302 of the upper and lower rows of terminals of the high-speed connector module 100 in this design are staggered one by one along the left and right directions, respectively. With the small spacing between the terminals of this type of high-speed connector module 100, the spacing between some high-speed terminals 1151 and 1152 and the insulating part of the third terminal module 13 is very small. In this design, in particular, a grounding terminal B close to the insulating part in the lower high-speed terminal 1152 of the first terminal module 11 and a grounding terminal B close to the insulating part in the upper high-speed terminal 1151 of the second terminal module 12 (see Figure 14 for details). Therefore, in this design, the corresponding positions on the left and right sides of the insulating part are recessed to form a avoiding groove 1300, so that there is enough gap between the grounding terminal B at the corresponding position and the side wall of the insulating part. Thus, the outer side of the corresponding grounding terminal B of the first terminal module 11 and the second terminal module 12 has a sufficient plastic coating thickness (that is, the side of the grounding terminal B close to the insulating part in the left and right directions has a sufficiently thick plastic coating) to ensure the fixing stability between the corresponding grounding terminal B and the insulating parts 1161, 1162 and the inner molds 1171, 1172. In this design, the avoidance groove 1300 is formed and extends along the entire length of the insulating part in the front-to-back direction.

The upper surface of the upper insulating member 1161 of the first terminal module 11 and the second terminal module 12, the lower surface of the lower insulating member 1162 and the upper surface of the insulating part are respectively protruded to form limiting columns 1011, and the inner wall surface of the insulating body 10 is correspondingly formed with a groove structure 1024, and the convex rib-shaped limiting columns 1011 are correspondingly fixed to the groove structure 1024, so as to realize the fixing of the first terminal module 11 and the second terminal module 12 with the insulating body 10 in the front-to-back direction, and the fixing of the third terminal module 13 with the insulating body 10 in the left-right direction and the up-down direction. In this design, the limiting posts 1011 on the first terminal module 11 and the second terminal module 12 are inverted hook-shaped boss structures protruding outward, and the limiting posts 1011 on the third terminal module 13 are dovetail-shaped rib structures protruding outward.

Please refer to Figures 1 to 6. The metal cover 2 is made of a metal plate and is formed with a docking space 20 extending in the front-to-back direction and a docking port 201 is formed at the front end (see Figure 2).

The upper cover body 22 is correspondingly arranged from top to bottom above the connector assembly 1 and is attached to the upper surface of the mounting portion 102 of the insulating body 10. The middle barrier 23 is installed from bottom to top and backward in the middle position of the upper cover body 22. The lower cover body 22 is arranged below the upper cover body 21 from bottom to top. In this design, the lower cover body 22 covers part of the lower surface of the mating portion 101 of the insulating body 10. The lower surface of the lower inner module 1172 of the first terminal module 11 and the second terminal module 12 and the lower surface of the insulating portion formed by stacking five insulating sheets 1311 are exposed downward from the clearance opening 1025 of the mounting portion 102 (see FIG. 6 ), and the metal bottom plate 3 is covered on the lower surface of the insulating body 10. The terminal docking portion 1303 of the third terminal assembly 131 and the plug pin 1143 of the grounding member 114 pass through the metal bottom plate 3 and protrude to the position below the metal bottom plate 3. In this design, since each terminal of the first terminal module 11 and the second terminal module 12 are designed to be connected to the cable 5. Therefore, only the terminal docking portion 1303 of each terminal of the third terminal assembly 131 and the plug pin 1143 of the grounding member 114 are arranged on the lower surface of the connector assembly 1, and the position is relatively concentrated. Therefore, the other parts of the lower surface of the connector assembly 1 are shielded and grounded through the metal bottom plate 3, which can further ensure and improve the shielding effect, which is conducive to improving the high-frequency performance.

Of course, in other embodiments, the metal bottom plate 3 may also be designed to be integrated with the lower cover 22 .

Please refer to FIG. 3 and FIG. 4 , the metal base plate 3 is fixed with the buckles on both sides of the metal cover 2.

The pin holes 1004 include a rear pin hole that penetrates the rear end position of the upper cover body 21, the rear seat body 14 and the metal base plate 3 in the up-down direction, and a front pin hole that penetrates the upper cover body 21, the insulating body 10, the front end position of the upper side plate 142 of the rear seat body 14 and the metal base plate 3 in the up-down direction. The high-speed connector module 100 also includes a plurality of pins 7 (or rivets). The pins 7 pass through the pin holes 1004 to fix the metal cover 2, the rear seat body 14, the metal base plate 3 and the insulating body 10 as a whole to ensure the overall structural stability of the high-speed connector module 100. Thereby, the high-speed connector module 100 can withstand a greater plug-in and pull-out force without being damaged or deformed. In this design, the pin holes 1004 are specifically located at the two sides of the rear end of the connector assembly 1.

Please refer to FIG. 1 and FIG. 2 , the heat dissipation module 4 includes a heat dissipation plate 41 and a heat dissipation guide post 42.

In this design, the heat dissipation guide post 42 is attached to the surface of the upper cover body 21 of the metal cover 2. The heat dissipation guide post 42 is used to export the heat on the rear seat body 14, and realizes the multi-channel heat dissipation function by connecting with the specific structure of the electronic device.

It should be noted that in this design, several non-high-speed terminals 130 are designed to be formed by stamping a metal plate in the thickness direction in the left-right direction (blank-type terminals), while several high-speed terminals 1151 and 1152 are designed to be formed by bending a metal plate in the thickness direction in the up-down direction. In this way, more signal design combinations (such as spacing, thickness, etc.) can be provided between each terminal group, which can make the characteristic impedance control between terminal pairs easier and more diversified. In addition, the stub effect can be eliminated. It is beneficial to the overall high-frequency characteristics of the high-speed connector module 100.
