On the side of the conductor holder 7 facing the terminal module 5, a shielding mesh 8 is provided, which shielding mesh 8 has windows 801 adapted to the respective sockets 701 on the conductor holder 7. The conductor frame 7 is made of conductive plastic or conductive plastic, and the shielding net 8 is a metal piece fixed on the conductor frame 7. The contact ends of the terminal modules 5 are inserted into the conductor holder 7 and the receptacle housing 6 in this order through the windows 801 of the shielding mesh 8. After insertion, the shielding frame 8 is held in place at the root of the contact end of the terminal module 5, forming a shielding layer laterally covering the entire connector mating section.

As shown in fig. 2 to 4, the shield contacts 503 of all the terminal modules 5 inserted into the receptacle housing 6 are in contact with the shield mesh 8, and the shield members of the terminal modules 5 are commonly grounded through the shield mesh 8 by the shield mesh. As shown in fig. 3 and 4, each window 801 of the shielding mesh 8 is provided with a first contact piece 802 protruding toward the center of the window, and thereby comes into contact with the shield contact 503 of the inserted terminal module 5. For example, a spring piece is provided which is pressed and deformed by its shield contact 503 when the terminal module 5 is inserted to apply elastic pressure to the shield contact. The first contact 802 in the form of a spring plate may be disposed at only one side of the window 501, or may be disposed at two opposite sides of each window 801. The spring pieces are in contact with the side wall portions 5031 of the inserted shield contact 503.

As shown in fig. 3, a first rib 702 is disposed inside the socket 701 of the conductor frame 7, and the protruding height of the first rib 702 enables the first rib to abut against a sidewall of the plug shielding plate 201 surrounding the differential signal contacts in the plug 2, so that the common grounding of the plug shielding assembly and the receptacle shielding assembly is realized, and the shielding effect is improved.

As shown in fig. 5 to 8, the conductor holder 7 is disposed between two side walls of the socket housing 6, and the insertion holes 701 on the conductor holder 7 are matched with the insertion grooves 601 in the socket housing 6. The shield contacts 503 of the terminal module 5 are inserted into the slots 601 in the socket housing 6 via the insertion openings 701 of the conductor mount 7.

The conductor frame 7 is composed of peripheral frames 703 and frame body partition plates 704 which are arranged between the peripheral frames 703 and divide the insertion openings 701, the height of the frame body on one side of the conductor frame 7 is smaller than that of the frame bodies on the other sides, and the frame body partition plates 704 form protruding portions 7041 below the frame bodies on the side. The root of one side wall of the socket shell 6 opposite to the narrow frame side of the conductor frame 7 is provided with a convex rib with the length equivalent to that of the conductor frame 7, and the height of the convex rib is equivalent to the difference between the narrow frame of the conductor frame 7 and the heights of other frames. The protruding rib on the side wall of the socket housing 6 is provided with a first locking groove 602 into which the protruding portion 7041 is inserted. A clamping protrusion 705 is arranged on the other side frame of the conductor frame 7, which deviates from the protruding portion 7041 of the frame body partition plate 704, and a second clamping groove 603 for clamping the clamping protrusion 705 is arranged on the side wall of the socket housing 6, which corresponds to the side frame.

As shown in fig. 9-13, the bottom of each slot 601 is provided with two symmetrical signal terminal contact slots 6013 separated by a differential signal terminal partition 6011, and the two signal terminal contact slots 6013 are respectively used for receiving the signal terminal contacts 5051 of the two signal terminals 505 constituting a differential signal pair in the terminal module 5.

As shown in fig. 10, the signal terminal contacts 5051 of both signal terminals 505 of a differential signal pair are inserted into and define positions by respective signal terminal contact slots 6013. Each signal terminal contact 5051 has two contact blades. A mating hole is formed in a position corresponding to an area between two contact blades in the signal terminal contact 5051 at the bottom of the signal terminal contact groove 6013 as shown in fig. 12, and a signal contact partition 6014 extending in the depth direction and used for separating the two contact blades in the signal terminal contact 5051 is formed in a position corresponding to the mating hole on a side wall of the signal terminal contact groove 6013.

The bottom of the slot 601 is provided with a built-in slot surrounding the two signal terminal contact slots 6013, into which the shielding contacts of the terminal module 5 and the plug shielding sheets in the plug can be inserted simultaneously, and the built-in slot is separated from the signal terminal contact slots 6013 by a surrounding plate 5012. The embedding slots include a shielding contact front-mounted slot 6016 extending along the arrangement direction of the two signal terminal contact slots 6013, a shielding contact side-mounted slot 6017 disposed on the side surface of one of the signal terminal contact slots 6013 and connected to one end of the shielding contact front-mounted slot 6016, and a shielding plate side-mounted slot disposed on the side surface of the other signal terminal contact slot 6013 and connected to the other end of the shielding contact front-mounted slot 6016, wherein the shielding contact front-mounted slot 6016 and the shielding contact side-mounted slots 6017 at the two ends thereof form a C-shaped through slot. The shape of the whole C-shaped through slot is matched with the shape of the plug shielding piece 201 surrounding the differential signal contact in the plug, and the plug shielding piece 201 can be inserted into the through slot. The shield contact front-mounted slot 6016 and the shield contact side-mounted slot 6017 may also be respectively used for inserting shield contacts in two directions in the terminal module 5.

For example, the terminal module 5 has two shield plates, a first shield plate and a second shield plate, respectively, and the shield contact at the lower end of each shield plate has a front shield claw, a side shield claw and a rear shield claw. The shield-contact front-mounting groove 6016 and the shield-contact side-mounting groove 6017 correspond to the front shield claw and the side shield claw, respectively, at the lower end of the shield plate. Meanwhile, the shielding contact inserted into the slot and the plug shielding sheet 201 are mutually compressed under the extrusion limit of the slot wall, so that the shielding effect of synchronous grounding is realized.

Among the plurality of slots 601 in the receptacle housing 6, one slot at the extreme end of each row of slots 601 is provided with a shield contact rear slot 6018 at the other side of the signal terminal contact slot 6013, which is opposite to the shield contact front slot 6016. The shield-contact-rear-slot 6018 can be inserted into the corresponding terminal-module shield contact (e.g., rear shield claw) and the plate-like shield piece in the plug at the same time.

A shielding contact partition 6015 is disposed on one inner side wall of each of the shielding contact front-located slot 6016 and the shielding contact rear-located slot 6018, and a gap is disposed between the shielding contact partition 6015 and the other inner side wall of the shielding contact front-located slot 6016 or the shielding contact rear-located slot 6018. One end of the shielding contact partition 6015 facing the bottom of the receptacle housing 6 is provided with a guiding inclined surface, and the other end is provided with a positioning step surface. The portion of the terminal module 5 where the front shielding claws at the lower ends of the two shielding plates meet can be held on the positioning step surface to define the insertion depth. The plug shield blades 201 may be inserted into the insertion grooves at the bottom of the insertion grooves 601 guided by the guide slopes and may be pressed by the shield contact partition 6015. The first rib 702 disposed inside the socket 701 of the conductor holder 7 is opposite to the shield contact partition 6015, and the plug shield 201 is pressed between the shield contact partition 6015 and the first rib 702, so that the plug shield 201 and the conductor holder 7 are grounded together. At the same time, the conductor holder 7 is provided with a connecting member (e.g., the first contact 802 of the shielding mesh 8) which is in contact with the shielding contact of the terminal module 5, so that the shielding members of the receptacle and the plug are grounded together as a whole, thereby improving the shielding effect.

As shown in fig. 14, a plurality of pairs of differential signal contacts 203 for connecting signal terminal contacts in a jack are fixed in the plug housing 202, and the periphery of each pair of differential signal contacts is shielded by the plug shield 201 shown in fig. 2. The plurality of header shields 201 are arranged in an array such that each pair of differential signal contacts 203 is disposed in a separate space surrounded by the header shields 201 as shown in fig. 2. The header shield sheet 201 includes a plurality of C-shaped shield sheets 204 and a plurality of plate-shaped shield sheets 205 as shown in fig. 14. The plurality of C-shaped shielding plates 204 are arranged in a rectangular array, and the directions of the C-shaped openings are the same. Each C-shaped shield 204 surrounds a pair of differential signal contacts 203. A plate-shaped shield plate 205 is provided on the opening side of the C-shaped shield plate that is open outward at the endmost one of the C-shaped shield plates in each row. The C-shaped shield plate 204 and the plate-shaped shield plate 205 are made of metal materials, and achieve a shielding effect after being grounded.

As shown in fig. 17 and 20, the plate-like shield piece 205 and the portion of the opposing C-shaped shield piece 204 inside the plug housing 202 are integrally connected by a first connecting arm 206, and the first connecting arm 206 abuts against the bottom of the board surface of the plug housing 202 after the plate-like shield piece 205 and the C-shaped shield piece 204 pass through the insertion slit 2021 on the board surface of the plug housing 202. The first connecting arm 206 serves both as a location for the protruding length of the plate-shaped shield piece 205 and the C-shaped shield piece 204 and as a support for the plate-shaped shield piece 205. By virtue of the support of the first connecting arm 206 and its associated C-shaped shield 204, the plate-like shield 205 is prevented from tilting so that its tip is too close to or too far from the intermediate differential signal contact 203. Meanwhile, the first connecting arm 206 surrounds the differential signal contact 203, and can enhance the shielding effect by cooperating with the C-shaped shielding plate 204 and the plate-shaped shielding plate 205.

To achieve a common grounding of the plurality of C-shaped shields 204, a plug grounding frame 207 abutting the C-shaped shields 204 may be arranged in the gaps of the array of plug shields 201 (i.e., the array of C-shaped shields 204). The plug grounding bracket 207 may be in the form of, for example, a first grounding bracket 208, a second grounding bracket 209 as shown in fig. 14, or a plug grounding bracket 207 as shown in fig. 21, or a plurality of grounding elements 210 as shown in fig. 21. The plug grounding frame 207 is provided with a protruding portion for abutting against the C-shaped shielding plate 204, and the plug grounding frame 207 is fixed on the plug housing 202 and simultaneously applies a transverse pushing force to the plurality of C-shaped shielding plates 204 abutting against the plug housing 202, so that the common grounding of the plurality of C-shaped shielding plates is realized while the C-shaped shielding plates 204 are positioned on the plug housing 202. Moreover, the plug grounding frame 207 extending along the transverse cross section of the plug housing 202 can form a mesh-shaped shielding layer at the root of the differential signal contact 203, which can further enhance the shielding effect.

As shown in fig. 14-16, in this embodiment, the plug grounding shelf 207 includes two first grounding shelves 208 and a plurality of second grounding shelves 209 disposed in the gaps between the array of C-shaped shields 204 (or the array of plug shields 201). The second grounding frame 209 is in a straight strip shape and is disposed between two adjacent rows of C-shaped shielding plates, and a plurality of protruding first contact portions 2091 for abutting against different C-shaped shielding plates are disposed on both sides of the second grounding frame 209. The two first grounding frames 208 are symmetrically disposed on two sides of the plug housing 202, and include a straight strip-shaped extension portion 2081 disposed along the outer side edge of the array of the plug shield blades 201 and a fixing portion 2082 that is branched from the extension portion 2081 and extends into a gap between adjacent C-shaped shield blades 204 (plug shield blades 201). The fixing portion 2082 extends into the gap along the outer wall surface on the C-seal side of one C-shaped shield sheet 204, and is in contact with the C-shaped shield sheet. The first grounding frame 208 and the second grounding frame 209 are embedded in the fixing groove 2022 formed at the bottom of the board surface of the plug housing 202. And a housing bottom clamping portion 2085 protruding from the end of the fixing portion 2082 to the side. The fixing groove 2022 has a groove section matched with the housing bottom clamping portion 2085, the housing bottom clamping portion 2085 is fixed in the fixing groove 2022 in a pressing manner, and a tightening force is applied to the extension portion 2081 through the fixing portion 2082 to make the extension portion 2081 abut against the side surface of the plug shielding piece 201. The side surface of the extension portion 2081 is provided with a plurality of protruding side wall contact portions 2083 for abutting different side surfaces of the C-shaped shielding sheets, the end portion of the fixing portion 2082 is provided with a protruding top wall contact portion 2084 for abutting the outer wall surface of the sealing side of the C-shaped shielding sheets, and the protruding direction of the shell bottom clamping portion 2085 is opposite to the protruding direction of the top wall contact portion 2084.

As shown in fig. 25, a simplified embodiment is shown, in which there is only a second grounding frame 209, and the common grounding of the plurality of C-shaped shielding plates 204 is achieved by a plurality of second grounding frames 209.

In another embodiment of the plug ground frame 207, as shown in fig. 21, the plug ground frame 207 is a grid frame type structure, each grid corresponding to a pair of differential signal contacts 203, and the C-shaped shields 204 on the periphery of the differential signal contacts 203 are inserted into the corresponding grids. The plug grounding frame 207 can be molded in the insulating material of the plug housing 202 as shown in fig. 22 to be integrated with the plug housing 202, so that the complicated steps during assembly are reduced. The plug ground bracket 207 has a second contact part 2071 protruding from the insulating material of the plug housing 202 on the mesh inner side wall thereof, and abuts against the C-shaped shield 204 by means of the second contact part 2071. Similarly, the plate-like shield 205 also abuts on the second contact part 2071 on the inner side wall of the mesh of the plug ground bracket 207. The plurality of second contact parts 2071 protruding toward the center around the inner side wall of the grid of the plug grounding frame 207 respectively apply a pushing force toward the center to each part of the C-shaped shielding plate 204 and the plate-shaped shielding plate 205, so that the C-shaped shielding plate 204 and the plate-shaped shielding plate 205 are clamped and positioned while good conductive contact is maintained, and the stability of the component assembly structure is realized. The plug grounding frame 207 with the grid frame type structure can also form a shielding layer on the transverse section of the plug shell 202, so that the shielding effect of the root position of the differential signal contact 203 is enhanced, and the signal crosstalk is further reduced.

Fig. 26 shows a variation of the embodiment shown in fig. 21, in which a notch 2072 is formed in the plug grounding frame 207 of the grid-frame structure at the C-shaped shielding plate corresponding to a top corner position in the array of C-shaped shielding plates 204, and the plug grounding frame 207 is broken and non-closed in the notch, so that the plug grounding frame 207 does not contact the C-shaped shielding plate at the top corner position. In this manner, the plug grounding bracket 207 is formed with a location at the notch to facilitate connector configuration and assembly.

Fig. 23 and 24 show a further embodiment of a plug grounding frame 207, in which the plug grounding frame 207 comprises a plurality of C-shaped grounding elements 210, the plurality of C-shaped grounding elements 210 being arranged between the array of C-shaped shield plates 204 to form a grounding grid. Each C-shaped shielding plate 204 corresponds to one grounding unit 210, and the C-shaped opening direction of the grounding unit 210 is opposite to that of the C-shaped shielding plate 204. The C-shaped openings of the grounding units 210 are clamped at two sides of the C-shaped shielding sheets 204 and are in contact with the adjacent grounding units 210 in the transverse direction, so that the side walls of the plurality of grounding units 210 between two adjacent rows of C-shaped shielding sheets are in contact with each other in sequence to realize the common conduction grounding in the transverse direction. The outer side wall of the C-shaped sealing side of the grounding unit 210 is provided with a lower grounding projection 2103 for abutting against the C-shaped shielding sheet at the sealing side, so that the common conduction grounding in the longitudinal direction is realized.

Grounding inner protrusions 2102 which are used for abutting against two sides of the C-shaped shielding sheet are arranged on the inner walls of two side walls of the grounding unit 210, and grounding outer protrusions 2101 which are used for abutting against adjacent grounding units in the same row are arranged on the outer wall of one side of the grounding unit 210.

In the embodiment shown in fig. 33-37, the C-shaped shield 204 is provided with a ground contact 2041 on one side wall and a resilient contact 2042 on the other side wall. The ground tab 2041 on the sidewall may be formed by bending a portion of the sidewall outward such that the ground tab 2041 is parallel to the middle tab of the C-shaped shield 204. In the embodiment shown in fig. 33 and 34, the elastic contact 2042 faces the side of the C-shaped shielding plate 204 and can abut against the side wall of the adjacent C-shaped shielding plate 204 from one side. In the embodiment shown in fig. 35-37, the elastic contact 2042 faces the opening of the C-shaped shielding plate 204 and can abut against the root of the grounding head 2041 of the adjacent C-shaped shielding plate 204, for example, abut against the table surface formed by bending the root of the grounding head 2041 as shown in fig. 37.

In the embodiment shown in fig. 38 and 39, in the array of C-shaped shielding plates 204, a common ground joint 2043 is provided between two adjacent C-shaped shielding plates in the same row, and the common ground joint 2043 is clamped in a seam 2044 formed at the end of the adjacent side wall of the two C-shaped shielding plates. The common ground joint 2043 can reduce the material consumption of the shielding pieces, and can realize the common grounding of the plurality of C-shaped shielding pieces in series connection, thereby improving the grounding and shielding effects.
