Technical Field

[0001] This utility model relates to the field of high-speed connector technology, and in particular to a high-speed connector with a shielding structure. Background Technology

[0002] High-speed connectors are connectors capable of supporting high data transmission rates. These connectors can transmit large amounts of data in a relatively short time, meeting the requirements of modern electronic devices for rapid data processing and transmission. High-speed connectors not only need to efficiently transmit electrical signals, but also need to ensure signal stability and reliability, avoiding data loss and interference.

[0003] Currently, to reduce the impact of external electromagnetic interference on the transmission rate and quality of electrical signals, shielding plates are typically placed inside high-speed connectors to reduce external electromagnetic interference. However, the shielding plates in current high-speed connectors are generally plugged into the connector itself, and this plug-and-play connection may result in weak contact between the shielding plate and the signal terminals, affecting the transmission rate and quality.

[0038] A plastic housing 10 is used to mount the signal terminal body 20. The plastic housing 10 is provided with a plug-in groove 100 that mates with the signal terminal body 20.

[0039] The signal terminal body 20 includes a 6-pin terminal 21, a 15-pin terminal 22, a 7-pin wafer terminal assembly 23, and a 40-pin wafer terminal assembly 24.

[0040] The 7PIN wafer terminal assembly 23 includes a 7PIN terminal 200, a first molding compound 201, and a first shielding sheet 202. The first molding compound 201 is fixedly connected to the 7PIN terminal 200, and the first shielding sheet 202 is disposed on the first molding compound 201 and fixedly connected to the first molding compound 201 through a first heat-riveting part.

[0041] This invention solves the problem of insecure contact between the shield and signal terminals, affecting transmission rate and quality, that often occurs when using current high-speed connectors. The first molding compound 201 is fixedly connected to the 7-pin terminal 200, and the first shield 202 is fixedly connected to the first molding compound 201 via a first heat-riveting part. Similarly, the 40-pin terminal assembly 24 consists of a 40-pin terminal 203, a second molding compound 204, and a second shield 205. The second molding compound 204 is fixedly connected to the 40-pin terminal 203, and the second shield 205 is fixedly connected to the second molding compound 204 via a second heat-riveting part. This addresses the issue of insecure contact between the shield and signal terminals, which can affect transmission rate and quality, in current high-speed connector applications.

The main slot 109 is disposed at the top of the plastic housing 10, and the first slot 110, second slot 111, third slot 112, and fourth slot 113 are disposed at the bottom of the plastic housing 10 and penetrate the plastic housing 10 from top to bottom. One end of the first slot 110, second slot 111, third slot 112, and fourth slot 113 communicates with the main slot 109, and the first slot 110, second slot 111, and third slot 112 are sequentially disposed on one side of the bottom of the plastic housing 10. The fourth slot 113 is located on the other side of the bottom of the plastic housing 10. The first slot 110 is configured to cooperate with the 7PIN wafer terminal assembly 23, which can be inserted into the first slot 110. The second slot 111 is configured to cooperate with the 6PIN terminal 21, which can be inserted into the second slot 111. The third slot 112 is configured to cooperate with the 15PIN terminal 22, which can be inserted into the third slot 112. The fourth slot 113 is configured to cooperate with the 40PIN wafer terminal assembly 24, which can be inserted into the fourth slot 113.

[0044] like Figure 2 , Figure 4 As shown, in order to better fix the first shielding sheet 202 to the first molding compound 201, thereby ensuring stable contact between the first shielding sheet 202 and the 7PIN terminal 200, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the first hot riveting part includes a plurality of first positioning parts 206. The plurality of first positioning parts 206 are disposed on the first molding compound 201 and integrally formed with the first molding compound 201. The first shielding sheet 202 is provided with a first positioning hole 207 that cooperates with the plurality of first positioning parts 206. The first positioning parts 206 and the first positioning holes 207 are interference-fitted. The end of the first positioning part 206 can be formed into a first fixing part 208 by hot riveting. The first positioning part 206 can be fixedly connected to the first positioning hole 207 through the first fixing part 208.

[0045] By fixing the first shielding sheet 202 to the first molding body 201 by hot riveting, it can be effectively ensured that the first shielding sheet 202 and the 7PIN terminal 200 maintain stable contact.

[0046] The first positioning parts 206 and the first positioning holes 207 are interference-fitted, which can realize the pre-positioning of the first shielding plate 202 during the hot riveting process, avoid the position of the first shielding plate 202 from shifting during the hot riveting process, and thus ensure the installation accuracy of the first shielding plate 202.

[0047] like Figures 7 to 8 As shown, in order to facilitate the installation of the 7PIN wafer terminal assembly 23, it is preferable that the first slot 110 is provided with a first mating groove 114 that cooperates with a plurality of first positioning parts 206 and first fixing parts 208, the first slot 110 is provided with a pair of first limiting blocks 115, and the first encapsulation body 201 is provided with a first limiting groove that cooperates with the first limiting blocks 115.

[0048] In use, the first mating groove 114 is configured to cooperate with the first positioning part 206 and the first fixing part 208, which facilitates the installation of the 7PIN wafer terminal assembly 23. At the same time, the first limiting block 115 and the first limiting groove facilitate the positioning and limiting functions during the installation of the 7PIN wafer terminal assembly 23.

[0049] In one embodiment, there are two first positioning parts 206 and two first positioning holes 207. The first positioning part 206 is fixedly connected to the first positioning hole 207 by forming a first fixing part 208 through hot riveting, which can make the structure of the first shielding sheet 202 and the first encapsulation body 201 more stable.

[0050] like Figure 3 , Figure 5 As shown, in order to better fix the second shielding sheet 205 to the second molding compound 204, thereby ensuring stable contact between the second shielding sheet 205 and the 40PIN terminal 203, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the second hot riveting part includes a plurality of second positioning parts 209. The plurality of second positioning parts 209 are disposed on the second molding compound 204 and integrally formed with the second molding compound 204. The second shielding sheet 205 is provided with second positioning holes 210 that cooperate with the plurality of second positioning parts 209. The second positioning parts 209 and the second positioning holes 210 are interference-fitted. The ends of the second positioning parts 209 can form second fixing parts 211 by hot riveting. The second positioning parts 209 can be fixedly connected to the second positioning holes 210 through the second fixing parts 211.

[0051] By fixing the second shielding sheet 205 to the second molding body 204 by hot riveting, it can be effectively ensured that the second shielding sheet 205 and the 40-pin terminal 203 maintain stable contact.

[0052] The interference fit between the second positioning parts 209 and the second positioning holes 210 enables the second shielding plate 205 to be pre-positioned during the hot riveting process, preventing the position of the second shielding plate 205 from shifting during the hot riveting process, thereby ensuring the installation accuracy of the second shielding plate 205.

[0053] like Figures 7 to 8As shown, in order to facilitate the installation of the 40PIN wafer terminal assembly 24, it is preferable that the fourth slot 113 is provided with a second mating groove 116 that cooperates with a plurality of second positioning parts 209 and a second fixing part 211, the fourth slot 113 is provided with a plurality of second limiting blocks 117, and the second encapsulation body 204 is provided with a second limiting groove that cooperates with the second limiting blocks 117.

[0054] In use, the second mating groove 116 is configured to cooperate with the second positioning part 209 and the second fixing part 211, which facilitates the installation of the 40PIN wafer terminal assembly 24. At the same time, the second limiting block 117 and the second limiting groove facilitate the positioning and limiting functions during the installation of the 40PIN wafer terminal assembly 24.

[0055] In one embodiment, the second positioning part 209 located at both ends and the middle of the second molding compound 204 can be configured to be an interference fit with the second positioning hole 210. The pre-positioning of the second shielding sheet 205 can be achieved by the interference fit between the three second positioning parts 209 and the second positioning hole 210. This method makes it easier to pre-install the second shielding sheet 205 with the second molding compound 204.

[0056] like Figure 6 As shown, in order to facilitate a more stable contact between the first shielding plate 202 and the 7PIN terminal 200, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the first shielding plate 202 is provided with a plurality of first spring sheets 212, which are integrally formed with the first shielding plate 202. Each set of first spring sheets 212 includes a first elastic sheet and a second elastic sheet. The first elastic sheet and the second elastic sheet are respectively disposed on both sides of the first shielding plate 202. The first elastic sheet and the second elastic sheet can contact the 7PIN terminal 200 to form a double contact structure.

[0057] The dual-contact structure allows the first shielding plate 202 to have two contact points with the 7PIN terminal 200, thereby enabling the first shielding plate 202 and the 7PIN terminal 200 to maintain a more stable contact.

[0058] The first shielding sheet 202 is provided with a pair of snap-fit ​​pieces 213, which are respectively disposed on both sides of the first shielding sheet 202 and integrally formed with the first shielding sheet 202. The first molding body 201 is provided with a pair of snap-fit ​​grooves 214 that cooperate with the pair of snap-fit ​​pieces 213. The pair of snap-fit ​​pieces 213 can be snapped into the pair of snap-fit ​​grooves 214 respectively and are interference fit with the snap-fit ​​grooves 214.

[0059] The snap-fit ​​piece 213 has double barb structures 215 on both sides, and the snap-fit ​​piece 213 can be press-fitted with the snap-fit ​​groove 214 through the double barb structures 215.

[0060] The design of the snap-fit ​​tab 213 and snap-fit ​​slot 214 allows for a more accurate pre-installation position of the first shielding plate 202. At the same time, the design of the snap-fit ​​tab 213 and snap-fit ​​slot 214 allows for more accurate contact between the first elastic plate and the second elastic plate and the corresponding 7PIN terminal 200.

[0061] like Figure 3 As shown, in order to facilitate a more stable contact between the second shielding plate 205 and the 40PIN terminal 203, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the second shielding plate 205 is provided with several sets of second springs 216, which are integrally formed with the second shielding plate 205. Each set of second springs 216 includes a third elastic sheet and a fourth elastic sheet. The third elastic sheet and the fourth elastic sheet are respectively disposed on both sides of the second shielding plate 205. The third elastic sheet and the fourth elastic sheet can contact the 40PIN terminal 203 to form a double contact structure.

[0062] The dual-contact structure allows the second shielding plate 205 to have two contact points with the 40-pin terminal 203, thereby ensuring a more stable contact between the second shielding plate 205 and the 40-pin terminal 203.

[0063] like Figures 7 to 8 As shown, in order to further ensure a more stable contact between the first shielding plate 202 and the 7PIN terminal 200, and a more stable contact between the second shielding plate 205 and the 40PIN terminal 203, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the insertion slot 100 is provided with a plurality of first protrusions 101 and a plurality of second protrusions 102. The plurality of first protrusions 101 are configured to cooperate with a plurality of first springs 212 and can form an interference fit with the plurality of first springs 212. The plurality of second protrusions 102 are configured to cooperate with a plurality of second springs 216 and can form an interference fit with the plurality of second springs 216.

[0064] In one embodiment, preferably, several sets of first protrusions 101 are disposed in the first slot 110, and each set of first protrusions 101 can contact the first elastic sheet and the second elastic sheet respectively to form interference, thereby enabling the first elastic sheet and the second elastic sheet to maintain more stable contact with the corresponding signal terminals in the 7PIN terminal 200; several sets of second protrusions 102 are disposed in the fourth slot 113, and each set of second protrusions 102 can contact the third elastic sheet and the fourth elastic sheet respectively to form interference, thereby enabling the third elastic sheet and the fourth elastic sheet to maintain more stable contact with the corresponding signal terminals in the 40PIN terminal 203.

[0065] like Figure 1 , Figures 9 to 11 As shown, CAP103 is an important component used when using an automatic machine nozzle to pick up products, transferring them from one location to another for PCB mounting. However, because the wall thickness of the plastic housing 10 corresponding to the 40-pin wafer terminal assembly 24 area is too thin, the product is prone to deformation after high-temperature reflow. To solve this problem, this embodiment modifies the above embodiment. The difference is that CAP103 is provided on the plastic housing 10, and CAP103 is inserted into the plastic housing 10. Two locking members 104 are provided on the bottom sides of CAP103, and a locking groove 105 is provided on the top of the plastic housing 10 to cooperate with the locking members 104, forming a double-sided locking mechanism. A protruding rib 106 is provided on the bottom of CAP103 to cooperate with the insertion groove 100, and the protruding rib 106 can be inserted into the upper end of the insertion groove 100.

[0066] The rib 106 is configured to cooperate with the upper end of the main groove 109 and can be inserted into the area of ​​the 40PIN wafer terminal assembly 24 in the main groove 109.

[0067] In use, the positioning parts 104 and positioning grooves 105 facilitate the assembly of CAP103 and plastic housing 10, and the protruding ribs 106 can cooperate with the main groove 109, thereby effectively improving the deformation of the main groove 109.

The plastic housing 10 is provided with a mounting groove 108 that cooperates with the grounding plates 107, and the grounding plates 107 can be snapped into the mounting groove 108. The grounding plates 107 can effectively realize the grounding function of the product described in this utility model.
