Specific Embodiments

[0087] As Figure 1-23 shown, an electrical connector assembly 100 in accordance with an embodiment of the present invention, the electrical connector assembly 100 includes an insulating housing 110 and a terminal module assembly 120 received in the insulating housing 110. The terminal module assembly 120 includes a pair of high-speed terminal modules 122 and a sideband terminal module 180 sandwiched between the pair of high-speed terminal modules 122. The insulating housing 110 includes a front mating groove 111 and a rear receiving cavity 112. A plurality of guiding grooves 116 are formed at the rear end of the insulating housing 110 for mating with the sideband terminal module 180 of the terminal module assembly 120. A plurality of fixing holes 114 are formed on the upper and bottom walls of the insulating housing 110 for mating with the high-speed terminal modules 122 of the terminal module assembly 120. A cutout (not labeled) is provided on the bottom wall of the insulating housing 110 to allow the tails of the terminals to extend towards a printed circuit board (not shown) on which the insulating housing 110 is mounted.

[0088] Each of the high-speed terminal modules 122 includes an upper unit 130 and a lower unit 130' stacked in the vertical direction. The upper unit 130 and the lower unit 130' are structurally similar or identical to each other and are arranged in a substantially symmetric manner in the vertical direction, thereby saving the design and manufacturing costs of the mold. Specifically, the upper unit 130 and the lower unit 130' are offset from each other in the lateral direction by a distance equal to half of the terminal pitch. Based on the similarity or identity between the upper unit 130 and the lower unit 130', only the upper unit 130 will be described in detail herein.

[0089] The upper unit 130 includes a metal housing 140 and a front or outer terminal sub-unit 160 and a rear or inner terminal sub-unit 170 assembled together through the metal housing 140. The outer terminal sub-unit 160 and the inner terminal sub-unit 170 together form a terminal unit 150. The outer terminal sub-unit 160 and the inner terminal sub-unit 170 are configured to be assembled and mated with each other in the vertical direction. The outer terminal sub-unit 160 includes a front or outer insulator 162 and a plurality of terminals 164 integrally formed within the front or outer insulator 162 by insert molding. The inner terminal sub-unit 170 includes a plurality of terminals 174 and a rear or inner insulator 172 integrally formed with the plurality of terminals 174. The plurality of terminals 164 includes three ground terminals 165 and two pairs of differential pair terminals 166. The three ground terminals 165 and the two pairs of differential pair terminals 166 are alternately arranged in the lateral direction, wherein the tails of the ground terminals 165 are connected together by a cross bar (not labeled). The manufacturing of the terminals 164 can refer to U.S. Provisional Application No. 63 / 004,068.

[0090] The outer insulator 162 is provided with a front protrusion 161 and three rear protrusions 163 for being received within a front opening 148 and a rear opening 149 of the metal housing 140. Three deformable posts 169 are provided on the outer insulator 162 for cooperating with a grounding member 300, which will be further described later. A plurality of receiving grooves 167 are formed on the bottom side of the outer insulator 162 for receiving the contact portions of the corresponding terminals 174 of the inner terminal sub-unit 170.

[0091] Correspondingly, the plurality of terminals 174 includes two pairs of differential pair terminals 176 and three ground terminals 175. The two pairs of differential pair terminals 176 and the three ground terminals 175 are alternately arranged. The tails of the ground terminals 175 are connected together by a cross bar (not labeled). The inner insulator 172 is provided with a plurality of front protrusions 173 and a plurality of rear protrusions 179. The front protrusions 173 cooperate with the corresponding rear protrusions 179 to be received together within the rear opening 149 of the metal housing 140. The rear edge of the metal housing 140 abuts against the rear protrusions 179.

[0092] It should be noted that through the cooperation of the front opening 148 and the rear opening 149 of the metal housing 140 with the front protrusion 161 and the rear protrusion 163 of the outer insulator 162 and the front protrusion 173 and the rear protrusion 179 on the inner insulator 172, the metal housing 140 and the outer insulator 162 and the inner insulator 172 are fixed to each other in the front-rear direction. The inner insulator 172 further includes a plurality of side protrusions 171 to be received in the corresponding fixing holes 146 to ensure the firmness of the metal housing 140 and the outer insulator 162 and the inner insulator 172 in the vertical direction and the front-rear direction. As Figure 16 shown, a plurality of protrusions 177 are formed on the lower side of the inner insulator 172 to be received in the corresponding recesses in the lower unit 130'. A recess 178 is formed on the bottom surface of the inner insulator 172 to receive the corresponding protrusions extending upward from the lower unit 130', thereby ensuring the holding force of the upper unit 130 and the lower unit 130' in the front-rear direction and the lateral direction.

[0093] It should be noted that after assembly, the metal housing 140 is held to the inner insulator 172 by engaging with the corresponding side protrusions 171 through the fixing holes 146, and the outer insulator 162 is sandwiched between the metal housing 140 and the inner insulator 172 in the vertical direction. The metal housing 140 of the upper unit 130 further includes a pair of holding portions 144 to hold to the corresponding holding portions of the metal housing of the lower unit 130'. In the outer insulator 162, a pair of channels (not labeled) are formed between the three rear protrusions 163 to allow the corresponding cables 200 to extend into. Similarly, a pair of upper channels 152 are formed on the upper side of the inner insulator 172 to receive the corresponding two cables 200 connected to the outer terminal sub-unit 160. A pair of lower channels 152 are formed on the lower side of the inner insulator 172 for receiving the two corresponding cables 200 connected to the inner terminal sub-unit 170. The metal housing 140 further includes a fixing piece 142, which will be firmly held in the fixing hole 114 when the terminal module assembly 120 is assembled into the insulating housing 110.

[0094] The cable 200 includes, from the inside to the outside, a pair of internal conductors 202, a pair of internal insulating layers 204, a common metallic or braided shielding layer 206, and a common external insulating layer (sheath). The internal conductors 202 are welded to the tails of the differential pair terminals 166, and the shielding layer 206 is mechanically and electrically connected to the crossbar of the ground terminal 165. The grounding member 300 is separately disposed from the ground terminal 165, and the grounding member 300 includes three holes 302, three arms 304, and two raised portions 306. The deformable post 169 extends through the holes 302 to fix the grounding member 300 to the outer insulator 162. The three arms 304 are respectively in contact and cooperation with the corresponding ground terminal 165. Each of the raised portions 306 can cover the entire exposed internal insulating layer 204 in the vertical direction. Compared with the conventional design where the exposed insulating layer 204 is not covered by a grounding member, covering the entire exposed internal insulating layer 204 by the raised portions 306 in the vertical direction can reduce the impedance. As required, the grounding member 300 can further cover the upper part of the front region of the shielding layer 206.

[0095] It should be noted that in the inner terminal sub-unit 170, the arrangement among the terminal 174, the inner insulator 172, and the cable 200 is similar to that in the outer terminal sub-unit 160, but in a symmetric or mirror image manner with respect to the outer terminal sub-unit 160. The metallic grounding member 300 of the outer terminal sub-unit 160 is assembled to the outer terminal sub-unit 160 along a first vertical direction, and the metallic grounding member of the inner terminal sub-unit 170 is assembled to the inner terminal sub-unit 170 along a second vertical direction opposite to the first vertical direction. The first vertical direction is the direction from top to bottom, and the second vertical direction is the direction from bottom to top. The shielding layer 206 of the cable 200 is located on the upper side of the corresponding crossbar of the ground terminal 165 of the outer terminal sub-unit 160 and on the lower side of the corresponding crossbar of the ground terminal 175 of the inner terminal sub-unit 170.

[0096] As Figure 18-22As shown, the sideband terminal module 180 includes a plurality of wafers 182 stacked on top of each other in the lateral direction. Each wafer 182 includes an insulator 184 and a terminal group 186 held in the insulator 184 by insert molding. The terminal group 186 includes an upper terminal unit 187 and a lower terminal unit 189. The upper terminal unit 187 includes a pair of contact arms 196 integrally formed in the upper terminal unit 187. The pair of contact arms 196 includes a front contact portion and a rear contact portion spaced apart in the front-rear direction. The lower terminal unit 189 includes a pair of contact arms 198 integrally formed. The pair of contact arms 198 includes a front contact portion and a rear contact portion spaced apart in the front-rear direction. The upper terminal unit 187 further includes a pair of tails 194 spaced apart from each other in the front-rear direction. The lower terminal unit 189 further includes a pair of tails 192 spaced apart from each other in the front-rear direction. The tails 192 and the tails 194 are for mounting to a printed circuit board. It should be noted that, if necessary, the pair of contact arms 196 can be electrically separated from each other by removing a T-shaped structure (not labeled) located between the corresponding pair of tails 194, because a stamping hole (not labeled) is formed in the insulator 184 to expose such a T-shaped structure. Similarly, the pair of contact arms 198 can be electrically separated from each other by removing a T-shaped structure (not labeled) located between the corresponding pair of tails 192. In fact, the contact arms 196 and the contact arms 198 are not in the same vertical plane, but are offset from each other in the lateral direction. Therefore, the insulator 184 forms a convex portion 183 and a concave portion 185 on both sides, thus forming such an offset structure. This offset structure also helps the wafers 182 to align and stack stably in the lateral direction. When viewed in the front-rear direction perpendicular to the lateral and vertical directions, each wafer forms an offset structure such that the upper terminal unit 187 is offset from the lower terminal unit 189 in the lateral direction. Each wafer 182 also forms a convex portion 188 to be received in a corresponding concave portion formed in an adjacent wafer 182. Each wafer 182 further includes a guiding rib 181 that is received in a corresponding guiding groove 116 during assembly. The thickness direction of the terminal group 186 is the lateral direction, while the thickness directions of the terminals 164 and 174 are perpendicular to the lateral direction.

[0097] As Figure 24-28As shown, another embodiment is illustrated. In this embodiment compared to the first embodiment, the arm 304 of the ground member 300 is replaced by the elastic arm 434 of the ground member 430, thus omitting the soldering process between the arm 304 and the corresponding ground terminal 175. In other words, in this embodiment, when the braided layer 456 is connected to the crossbar (not labeled) of the ground terminal 450, the elastic arm 434 mechanically presses the corresponding ground terminal 450 without soldering. It can be understood that in this embodiment, all other components remain the same as those of the first invention. The outer terminal sub-unit includes a plurality of terminals 336 held in the insulator 332, and the inner terminal sub-unit includes a plurality of terminals 338 held in the insulator 334. The ground member 430 is held to the insulator 332 by the post 460. The cable 451 is composed of an inner conductor 452, an inner insulating layer 454, a braided layer 456, and an outer insulating layer 458. It is worth noting that in the present invention, the ground member 300 and the ground member 430 substantially cover most of the exposed inner insulating layer 204 and the inner insulating layer 454 in the vertical direction to reduce their impedance. It is worth noting that the insulating housing 110 forms a plurality of channels (not labeled) beside the front mating groove 111 to respectively accommodate the contact portions of the corresponding terminals. The terminal group 186 is stamped and elastically deflectable in a direction perpendicular to the thickness direction of the terminal group, and the terminals 164 and 174 are stamped and elastically deflectable in a direction consistent with the terminal thickness direction.

[0098] As Figure 29-33As shown, another embodiment is illustrated. In this embodiment, only the arm 304 of the metal ground piece 500 is omitted, and other components are the same as those in the first embodiment. The front terminal sub-unit includes a plurality of terminals 536 held in the insulator 532. The rear terminal sub-unit includes a plurality of terminals 538 held in the insulator 534. The terminals 536 include three ground terminals 547 and two pairs of differential pair terminals 546 arranged alternately with the three ground terminals 547 in the lateral direction. The tails of the ground terminals 547 are connected together by a cross bar 540. The terminals 538 include three ground terminals 549 and two pairs of differential pair terminals 548 arranged alternately with the three ground terminals 549 in the lateral direction. The tails of the ground terminals 549 are connected together by a cross bar 540. The metal ground piece 500 is not held on the insulator 532 by a post 460. The ground piece 500 includes two raised portions 504 and three horizontal portions 505. The cable 551 is composed of an inner conductor 552, an inner insulating layer 554, a common metal shielding layer 556, and an outer insulating layer 558. Each of the raised portions 504 covers the exposed common metal shielding layer 556, and each of the horizontal portions 505 is connected to the corresponding ground terminal 547. A hole 510 is provided in each of the raised portions 504 and each of the horizontal portions 505, and the metal ground piece 500 is directly welded to the cross bar 540 of the ground terminal 547 and the common metal shielding layer 556 through the holes 510.
