Abstract
Description
Technical Field
[0001] This invention relates to the field of high-speed connector technology, and in particular to a high-speed connector shielding structure and method. Background Technology
[0002] High-speed connectors offer a highly reliable data transmission capability. They provide a high-performance, highly reliable, and compact connection solution, offering a reliable solution for high-speed, high-power, and high-speed signal transmission. However, during use, crosstalk can occur between differential pairs in high-speed connectors, and external electromagnetic interference can also affect the connector. These two issues reduce the transmission efficiency of high-speed connectors.
[0003] To address these two issues, existing high-speed connectors typically employ a shielded outer shell followed by shielding components between the differential pairs. However, most existing shielding components only provide shielding on one or two sides, and their sides are relatively narrow. This results in poor shielding effectiveness against crosstalk between differential pairs and interference from external electromagnetic sources. Furthermore, the complex connector structure makes installation inconvenient, and the fabrication of the shielding components is also quite troublesome.
[0004] The invention disclosed in application number 202010066020.4 and publication number CN111092342B is a socket for a high-speed connector, including an insulator, on which signal terminals and shielding components are fixed. The signal terminals are arranged in at least one row, and the shielding components are arranged in rows corresponding to each signal terminal. The shielding components include a first type of shielding component and a second type of shielding component. The first type of shielding component has a lateral opening, but it still has the problem of poor shielding effect against crosstalk between differential pairs and interference from external electromagnetic fields. Moreover, due to the complex structure of the connector, the installation of the shielding component is very inconvenient, and the processing of the shielding component is also quite troublesome. Summary of the Invention

[0018] A method for using a high-speed connector shielding structure, applied to the aforementioned high-speed connector shielding structure, comprises the following steps:
[0019] A: Pre-installation;
[0020] A1: Pre-installed cable termination assembly;
[0021] Connect the wire end shielding mounting plate, connecting plate and plug part, install the wire end differential pairs in the mounting groove respectively, weld the high-speed cable to one end of the wire end differential pair, and pass the other end through the plug part to complete the installation of the wire end structure.

[0032] When the line-end assembly is inserted into the board-end assembly, the shielding block and mounting block on the board-end shielding mounting plate are inserted into the inner mounting slot on the line-end shielding mounting plate, making contact between the line-end differential pair and the board-end differential pair. At the same time, the shielding block and mounting block are inserted into the mounting slot, forming an independent shielding space for each mounting slot. This makes the line-end differential pair in each mounting slot independent of the board-end differential pair, effectively reducing crosstalk between differential pairs. In addition, the setting of the board-end shielding mounting plate and the line-end shielding plate can also effectively reduce the impact of external electromagnetic interference on the differential pairs.
[0033] This invention solves the problem that existing high-speed connectors have poor shielding performance against crosstalk between differential pairs and interference from external electromagnetic sources. Furthermore, the complex structure of the connector makes installation very inconvenient, and the processing of the shielding components is also quite troublesome. Attached Figure Description

Detailed Implementation
[0044] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0045] Example:
[0046] like Figures 1 to 8 As shown, this embodiment discloses a high-speed connector shielding structure, including a housing assembly 10, a board end assembly 20 and a wire end assembly 30, with the board end assembly 20 and the wire end assembly 30 being inserted together, and the housing assembly 10 being sleeved on the outside of the board end assembly 20 and the wire end assembly 30.
[0047] The line terminal assembly 30 includes a pair of mating line terminal structures 300. Each line terminal structure 300 includes a line terminal shielding mounting plate 301, a connecting plate 302, a plug-in portion 303, a high-speed cable 304, and a plurality of pairs of line terminal differential pairs 305. The connecting plate 302 is disposed between the plug-in portion 303 and the line terminal shielding plate. The line terminal shielding mounting plate 301 is provided with a plurality of mounting grooves 306. The line terminal differential pairs 305 are disposed in the mounting grooves 306. One end of the high-speed cable 304 is connected to the line terminal differential pair 305, and the other end extends outward through the plug-in portion 303.
[0048] The board end assembly 20 includes a pair of board end structures 200 that are configured to cooperate. The board end structure 200 includes a board end shielding mounting plate 201 and a plurality of pairs of board end differential pairs 204. The board end shielding mounting plate 201 is provided with a plurality of shielding blocks 202 and mounting blocks 203 that are configured to cooperate with the mounting groove 306. The board end differential pairs 204 are disposed on the mounting blocks 203.
[0049] When the line terminal assembly 30 is inserted into the board terminal assembly 20, the shielding block 202 and mounting block 203 on the board terminal shielding mounting plate 201 are inserted into the inner mounting slot 306 on the line terminal shielding mounting plate 301. The line terminal differential pair 305 is in contact with the board terminal differential pair 204. At the same time, the shielding block 202 and mounting block 203 are inserted into the mounting slot 306, forming an independent shielding space for each mounting slot 306. This makes the line terminal differential pair 305 in each mounting slot 306 independent from the board terminal differential pair 204, effectively reducing crosstalk between differential pairs. At the same time, the setting of the board terminal shielding mounting plate 201 and the line terminal shielding plate can also effectively reduce the impact of external electromagnetic interference on the differential pairs.
[0050] This invention solves the problem that existing high-speed connectors have poor shielding performance against crosstalk between differential pairs and interference from external electromagnetic sources. Furthermore, the complex structure of the connector makes installation very inconvenient, and the processing of the shielding components is also quite troublesome.
[0051] At the same time, the plate-shaped shielding structure is easier to manufacture than the shielding components used in traditional high-speed connectors, and there is no need to consider how to install the shielding components into the high-speed connector.
[0052] like Figure 1 , Figure 6 As shown, for ease of installation and disassembly, this embodiment, based on the above embodiment, is further preferred in that, unlike the above embodiment, the housing assembly 10 includes an upper housing 100 and a lower housing 101. The upper housing 100 and the lower housing 101 are detachably connected by a snap fastener 102, and have a mounting cavity for mounting the plate end assembly 20 and the wire end assembly 30. Both plate end structures 200 are disposed in the mounting cavity, and the back of one plate end structure 200 is fixedly connected to the inner wall of the upper housing 100 by screws, and the back of the other plate end structure 200 is fixedly connected to the inner wall of the lower housing 101 by screws. There is an insertion gap 205 between the two plate end structures 200 for inserting the wire end assembly 30, which can be inserted into the insertion gap 205.
[0053] like Figure 7As shown, preferably, there are two fasteners 102, which are respectively disposed on both sides of the housing assembly 10. The fasteners 102 include an elastic fastener 103 and a mating fastener 104. The elastic fastener 103 is disposed on the upper housing 100 and is fixedly connected to the upper housing 100. The mating fastener 104 is disposed on the lower housing 101 and is fixedly connected to the lower housing 101. The elastic fastener 103 is provided with a limiting protrusion 105 that mates with the mating fastener 104. When the elastic fastener 103 is inserted into the mating fastener 104, a limiting protrusion 105 and the mating fastener 104 are formed. Pressing the elastic fastener 103 can release the limiting protrusion 105 from the mating fastener 104.
[0054] In use, the line end assembly 30 and the board end assembly 20 are connected by a plug-in method, which can facilitate quick connection and disconnection; the buckle 102 allows the upper housing 100 and the lower housing 101 to be quickly fixed and disassembled. In case of inspection, maintenance or other situations that require opening the housing for inspection, the upper housing 100 and the lower housing 101 can be quickly separated, and the buckle 102 can also stably fix the upper housing 100 and the lower housing 101.
[0055] like Figure 4 , Figure 8 As shown, in order to facilitate quick insertion between the line end assembly 30 and the board end assembly 20, and also to increase the stability of the structure of the present invention, this embodiment, based on the above embodiment, is further preferred in that, unlike the above embodiment, the line end shielding mounting plate 301 is provided with sliding insertion grooves 307 on both sides, and the board end shielding mounting plate 201 is provided with sliding blocks 206 that cooperate with the sliding insertion grooves 307. The sliding blocks 206 and the sliding insertion grooves 307 are slidably engaged and can be fixed by friction. The bottom of the sliding insertion grooves 307 is provided with limiting grooves 308, and the sliding blocks 206 are provided with limiting sliders 207 that cooperate with the limiting grooves 308. The limiting sliders 207 and the limiting grooves 308 are slidably engaged and can be fixed by friction.
[0056] In use, simply insert the sliding block 206 on the end shielding mounting plate into the sliding insertion slot 307 on the line end shielding mounting plate 301 to achieve quick and accurate connection between the line end assembly 30 and the plate end assembly 20. The cooperation between the limiting slider 207 and the limiting groove 308 makes the connection between the two plate end structures 200, the upper housing 100 and the lower housing 101 tighter, avoiding the situation where the upper housing 100 and the lower housing 101 are easily separated due to accidental contact with the fastener 102.
[0057] like Figure 4As shown, in order to ensure the stability of the structure of the present invention, this embodiment is further preferred on the basis of the above embodiment, in that, the line end shielding mounting plate 301 is provided with a plurality of mounting protrusions 309 at one end, the mounting protrusions 309 and the connecting plate 302 are fixedly connected by screws, and the high-speed cable 304 is welded to the end of the line end differential pair 305.
[0058] Preferably, the connecting plate 302 and the plug-in part 303 are integrally formed.
[0059] The wire end shielding mounting plate 301 is fixedly connected to the connecting plate 302 by screws through the cooperation of the mounting protrusion 309 and screws. The connecting plate 302 and the plug part 303 are integrally formed, so that the wire end assembly 30 can be directly pulled out through the plug part 303.
[0060] like Figure 4 As shown, in order to facilitate insertion into the accurate position, this embodiment is further preferred on the basis of the above embodiment, the difference from the above embodiment is that a limiting piece 310 is provided at one end of the mounting groove 306 on the wire end shielding mounting plate 301 near the connecting plate 302, and the limiting piece 310 is fixedly connected to the wire end shielding mounting plate 301.
[0061] When the line end assembly 30 is inserted into the board end assembly 20, the shielding block 202 needs to contact the limiting plate.
[0062] like Figure 5 As shown, in order to facilitate the assembly of the line end assembly 30, this embodiment, based on the above embodiment, is further preferred in that, unlike the above embodiment, the two line end structures 300 are positioned by the cooperation of positioning post 311 and positioning hole 312, and the positioning post 311 and positioning hole 312 are respectively set on the back of the line end shielding mounting plate 301.
[0063] Preferably, the positioning pin 311 can be inserted into the positioning hole 312 and fixed to the positioning hole 312 by friction.
[0064] like Figure 3As shown, in order to ensure the stability of the wire end assembly 30 and strengthen the connection between the wire end assembly 30, the plate end assembly 20, and the housing assembly 10, this embodiment, based on the above embodiment, is further preferred in that, unlike the above embodiment, the two wire end structures 300 are fixed together by a locking member 313. The locking member 313 includes a locking plate 314, an elastic arm 315, and a locking head 316. The two ends of the locking plate 314 are respectively disposed on the insertion portions 303 in the two wire end structures 300, and are fixedly connected to the insertion portions 303 by screws. The elastic arm 315 is disposed on the locking plate 314, and the locking head 316 is disposed on one end of the elastic arm 315. The housing assembly 10 is provided with a slot 106 that cooperates with the locking head 316, and the insertion portion 303 is provided with a slot 317.
[0065] When the wire end assembly 30 is inserted into the board end assembly 20, the elastic arm 315 needs to be moved so that the clip 316 is locked in the slot 106, thus completing the locking and fixing between the wire end assembly 30 and the housing assembly 10. When disassembly is required, the elastic arm 315 needs to be moved so that the clip 316 is disengaged from the slot 106, and the wire end assembly 30 can be pulled out by prying out the slot 317.
[0066] like Figure 6 As shown, in order to facilitate insertion and removal of the present invention during use, this embodiment is further preferred based on the above embodiment, in that, unlike the above embodiment, both the upper housing 100 and the lower housing 101 include a front insertion portion 107 and a rear handheld portion 108. One end of the plate end differential pair 204 extends into the insertion portion 107. The insertion portion 107 is provided with a shielding partition plate 109 for separating the plate end differential pair 204. The handheld portion 108 is provided with an anti-slip protrusion 110.
[0067] The anti-slip ridge 110 serves to prevent slipping, the interlocking part 107 facilitates insertion, and the shielding partition 109 provides a certain degree of shielding.
[0068] like Figures 1 to 8 As shown, a method for using a high-speed connector shielding structure, applied to the aforementioned high-speed connector shielding structure, comprises the following steps:
[0069] A: Pre-installation;
[0070] A1: Pre-installed terminal assembly 30;
[0071] Connect the wire end shielding mounting plate 301, the connecting plate 302 and the plug-in part 303, install the wire end differential pair 305 in the mounting groove 306 respectively, weld the high-speed cable 304 to one end of the wire end differential pair 305, and pass the other end through the plug-in part 303 to complete the installation of the wire end structure 300. After the positioning pins 311 on the back of the two matching wire end structures 300 are aligned with the positioning holes 312, insert them into the machine. Install the locking piece 313 on the wire end structure 300 with screws to complete the installation of the wire end assembly 30.
[0072] The connecting plate 302 and the plug-in part 303 can be integrally formed, the wire end shielding mounting plate 301 and the mounting protrusion 309 can be integrally formed, the mounting protrusion 309 and the connecting plate 302 are fixed by screws, and the plug-in part 303 has a through hole adapted to the high-speed cable 304, through which the high-speed cable 304 passes.
[0073] A2: Pre-installed board-end assembly 20;
[0074] Connect the shielding block 202 and the mounting block 203 to the board end shielding mounting plate 201, install the board end differential pair 204 on the mounting block 203 to complete the installation of the board end structure 200, and fix the two matching board end structures 200 in the upper housing 100 and the lower housing 101 respectively with screws to complete the installation of the board end assembly 20.
[0075] The mounting block 203 and the plate end shielding mounting plate 201 can be integrally formed. One end of the shielding block 202 can be embedded in the plate end shielding mounting plate 201, or fixed to the plate end shielding mounting plate 201 with adhesive. The plate end differential pair 204 can be embedded in the mounting block 203, or fixed to the mounting block 203 with adhesive or other fixing methods.
[0076] A3: Pre-installed housing assembly 10;
[0077] The snap fasteners 102 are installed on both sides of the housing assembly 10, wherein the elastic snap fasteners 103 are installed on the upper housing 100, and the mating snap fasteners 104 are installed on the lower housing 101. The upper housing 100 and the lower housing 101 are locked together by the snap fasteners 102, thus completing the installation of the housing assembly 10.
[0078] B: Use;
[0079] B1: Connection;
[0080] When connection is required, insert the wire end component 30, which is installed in step A, into the housing component 10 after it corresponds to the board end component 20. Lock the wire end component 30 and the housing component 10 with the locking piece 313. Then, align the board end component 20 with the connection point that needs to be plugged in, and insert the housing component 10 to complete the connection.
[0081] B2: Disconnect;
[0082] When it is necessary to disconnect, move the elastic arm 315 in the locking member 313 to disengage the clip 316 from the clip slot 106 on the housing assembly 10. After holding the prying slot 317 with your hand, pry out the wire end assembly 30 to disconnect.
[0083] Working principle of this invention:
[0084] When the line terminal assembly 30 is inserted into the board terminal assembly 20, the shielding block 202 and mounting block 203 on the board terminal shielding mounting plate 201 are inserted into the inner mounting slot 306 on the line terminal shielding mounting plate 301. The line terminal differential pair 305 is in contact with the board terminal differential pair 204. At the same time, the shielding block 202 and mounting block 203 are inserted into the mounting slot 306, forming an independent shielding space for each mounting slot 306. This makes the line terminal differential pair 305 in each mounting slot 306 independent from the board terminal differential pair 204, effectively reducing crosstalk between differential pairs. At the same time, the setting of the board terminal shielding mounting plate 201 and the line terminal shielding plate can also effectively reduce the impact of external electromagnetic interference on the differential pairs.
[0085] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
