Electromagnetic interference may introduce noise, distort the signal waveform, increase the bit error rate, and thus affect the performance of the entire system. Therefore, with the continuous development of modern electronic devices, how to improve the electromagnetic shielding effect will play an increasingly important role in the field of high-speed connectors.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] High - speed connectors generally include a plurality of connector terminals (also referred to as wafer structures). For the convenience of description, the following embodiments introduce the technical solutions of the present invention by taking one connector terminal as an example.

[0035] As Figures 1-6As shown, the connector terminal of an embodiment includes an insulating frame assembly 10, a plurality of signal terminal assemblies 20, a plurality of ground terminal assemblies 30, and a shielding assembly 40. The plurality of signal terminal assemblies 20 are located within the insulating frame assembly 10, and each signal terminal assembly 20 includes two oppositely arranged signal terminals; the plurality of ground terminal assemblies 30 are arranged within the insulating frame and adjacent to the signal terminal assemblies 20, and each ground terminal assembly 30 includes two oppositely arranged ground terminals; the shielding assembly 40 includes two shielding sheets, which are respectively arranged on opposite sides of the insulating frame assembly 10, and at least a part of the side of the ground terminal facing the shielding sheet exposes the insulating frame assembly 10, and the shielding sheet contacts the ground terminal through the exposed part of the ground terminal.

[0036] For the above connector terminal, the signal terminal assemblies 20 and the ground terminal assemblies 30 are arranged adjacent to each other. Ground terminals are arranged on both sides of each signal terminal. At least a part of the side of the ground terminal facing the shielding sheet exposes the insulating frame assembly 10, and the shielding sheet contacts the ground terminal through the exposed part of the ground terminal. Therefore, the ground terminals on both sides and the shielding sheet on the back form a semi-closed shielding structure around the signal terminals, reducing the influence of electromagnetic interference on the signal quality and improving the electromagnetic shielding effect and the signal transmission performance.

[0037] The signal terminal assemblies 20 are located within the insulating frame assembly 10 and are used to transmit signals. As Figure 1 and Figure 3 shown, the signal terminal assembly 20 includes a contact end 200, a mounting end 202, and a transmission portion 204. Among them, the contact end 200 is used to connect with other connectors, and the mounting end 202 is used to connect with a PCB circuit board or other components. The transmission portion 204 is located between the contact end 200 and the mounting end 202 and is the transmission path of the signal terminal. Each signal terminal assembly 20 includes two oppositely arranged signal terminals. The two signal terminals are arranged in an opposite manner, so that the two signal terminals are located on different layers, and data is transmitted between them through the entire spectrum of the transmitted signal. That is, wide-side coupling. In this embodiment, the two oppositely arranged signal terminals form a differential signal pair. Therefore, in this embodiment, the plurality of signal terminal assemblies 20 are a plurality of wide-side coupled differential signal pairs. In addition, it should be noted that the number of signal terminal assemblies 20 can be selected according to the actual situation and is not limited here. The plurality of signal terminal assemblies 20 are evenly arranged within the insulating frame assembly 10.

[0038] The insulating frame assembly 10 is used to support and protect the internal signal terminals and is generally made of ceramic, plastic, or other insulating materials. As Figure 1 shown, in this embodiment, the insulating frame assembly 10 includes a connected first insulating frame 110 and a second insulating frame 120. The two oppositely arranged signal terminals are respectively arranged within the first insulating frame 110 and the second insulating frame 120. As Figure 1 andFigure 5 As shown, taking one of the signal terminal assemblies 20 as an example, the signal terminal assembly 20 includes a first signal terminal 210 and a second signal terminal 220 which are oppositely arranged. The first signal terminal 210 is located within the first insulating frame 110, and the second signal terminal 220 is located within the second insulating frame 120. The first signal terminal 210 and the second signal terminal 220 are respectively fixed within the first insulating frame 110 and the second insulating frame 120 by plastic injection molding. Among them, the first insulating frame 110 and the second insulating frame 120 can be connected together by snap connection, fitting or gluing. After the first insulating frame 110 and the second insulating frame 120 are connected together, the first signal terminal 210 corresponds to the second signal terminal 220, forming a differential signal pair.

[0039] As Figure 7 shown, in other embodiments, the insulating frame assembly 10 can also be an integral body, and the first signal terminal 210 and the second signal terminal 220 are injection molded in the insulating frame assembly 10 in the form of a differential pair.

[0040] The ground terminal assembly 30 has good electrical conductivity. By grounding, the ground terminal can reduce interference and noise during signal transmission, improving the transmission quality and stability of the signal. In this embodiment, the ground terminal assembly 30 is arranged adjacent to the signal terminal assembly 20. Among them, being arranged adjacent means that the ground terminal assembly 30 and the signal terminal assembly 20 are spaced a certain distance and are adjacent. That is, the ground terminal assembly 30 and the signal terminal assembly 20 are arranged in the order of ABABABA (where A represents the ground terminal assembly 30 and B represents the signal terminal assembly 20). Therefore, the ground terminal assembly 30 is arranged on both sides of the signal terminal assembly 20, thus forming a semi-surrounding structure for the signal terminal assembly 20 together with the shielding assembly 40, improving the electromagnetic shielding effect. In addition, with the ground terminal assembly 30 and the signal terminal assembly 20 arranged as described above, the ground terminal assembly 30 located between the two signal terminal assemblies 20 is the common ground terminal for the two signal terminal assemblies 20.

[0041] As Figure 2 , Figure 3 and Figure 5 shown, the ground terminal assembly 30 is arranged adjacent to the signal terminal assembly 20. Each ground terminal assembly 30 includes two oppositely arranged ground terminals. Taking one of the ground terminal assemblies 30 as an example, the ground terminal assembly 30 includes a first ground terminal 310 and a second ground terminal 320. The first ground terminal 310 is adjacent to the first signal terminal 210, and the second ground terminal 320 is adjacent to the second signal terminal 220. Similarly, the ground terminal assembly 30 is the common ground terminal assembly for the signal terminal assemblies 20 on both sides.

[0042] The insulating frame assembly 10 is used to fix and support the signal terminal assembly 20 and the ground terminal assembly 30. In this embodiment, the insulating frame assembly 10 is a hollow structure, so that when the ground terminal assembly 30 is disposed in the insulating frame assembly 10, a part of the ground terminal assembly 30 will be exposed from the insulating frame assembly 10. For example, as Figure 2 shown, each ground terminal assembly 30 is exposed from the insulating frame assembly 10 to contact the shielding assembly 40.

[0043] Please continue to refer to Figure 1 and Figure 5 , the shielding assembly 40 includes two shielding sheets. Taking the side close to the first signal terminal 210 as the first shielding sheet 410 and the side close to the second signal terminal 220 as the second shielding sheet 420 as an example. The first shielding sheet 410 contacts the first ground terminal 310 through the exposed part of the first ground terminal 310, and the second shielding sheet 420 contacts the second ground terminal 320 through the exposed part of the second ground terminal 320. The first shielding sheet 410 and the two first ground terminals 310 form a semi-closed structure for the first signal terminal 210, which is beneficial to reducing electromagnetic interference. Similarly, the second shielding sheet 420 and the two second ground terminals 320 form a semi-closed structure for the second signal terminal 220.

[0044] Both the shielding assembly 40 and the ground terminal assembly 30 have conductivity. Contacting the shielding assembly 40 and the ground terminal assembly 30 can achieve the effect of grounding and form a shielding structure around the signal terminal assembly 20. Taking the first shielding sheet 410 and the first ground terminal 310 as an example, the contact between the first shielding sheet 410 and the first ground terminal 310 can be either lapping or butting, as long as the contact between the first shielding sheet 410 and the first ground terminal 310 can achieve the effect of reducing electromagnetic interference.

[0045] In this embodiment, the shielding assembly 40 is provided with a protrusion 42 on the side close to the ground terminal assembly 30, and the shielding sheet is connected to the ground terminal assembly 30 through the protrusion 42. The protrusion 42 is disposed on the side of the shielding sheet close to the ground terminal assembly 30, that is, the protrusion 42 is higher than the inner surface of the shielding sheet, so that the shielding assembly 40 can be more accurately contacted with the ground terminal assembly 30. Among them, the protrusion 42 can be a structure with conductive performance, and is welded or integrally formed with the shielding assembly 40.

[0046] Furthermore, as Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, each shielding sheet includes a first surface close to the grounding terminal assembly 30 and a second surface far from the grounding terminal assembly 30. The shielding sheet extends from the second surface toward the first surface to form a protruding portion 42, and the shielding sheet contacts the grounding terminal through the protruding portion 42. Taking the first shielding sheet 410 in the shielding assembly 40 as an example, the first shielding sheet 410 extends toward the first grounding terminal 310 to form a protruding portion 42. When the first shielding sheet 410 is installed on the insulating frame assembly 10, the protruding portion 42 contacts the first grounding terminal 310. The first surface is the inner surface of the shielding sheet, and the second surface is the outer surface of the shielding sheet. The protruding portion 42 is a part of the shielding assembly 40 and is formed by the shielding sheet in the shielding assembly 40 recessing from the second surface toward the first surface. That is, the protruding portion 42 is integrally formed with the shielding assembly, improving the convenience of manufacturing the protruding portion 42.

[0047] Furthermore, in this embodiment, the protruding portion 42 is arranged on the shielding sheet along a direction parallel to the transmission path of the grounding terminal. As Figures 1-3 shown, the grounding terminal assembly 30 extends within the insulating frame assembly 10. For example, it extends from one side of the insulating frame assembly 10 to the opposite side or an adjacent side, and this extension path is the transmission path of the grounding terminal. In addition, the transmission path of the grounding terminal assembly 30 matches the transmission path of the signal terminal assembly 20. That is, the transmission paths of the grounding terminal assembly 30 are provided on both sides of the transmission path of the signal terminal assembly 20. The protruding portion 42 is arranged on the shielding assembly 40 and along a direction parallel to the transmission path of the grounding terminal assembly 30, increasing the contact area and convenience between the protruding portion 42 and the grounding terminal assembly 30.

[0048] Since the grounding terminal assembly 30 and the signal terminal assembly 20 are arranged adjacent to each other, grounding terminals are provided on the side of the signal terminal assembly 20. Similarly, the transmission paths of the grounding terminals are also provided on the sides of the transmission path of the signal terminal. In this embodiment, the projection of the transmission path of the signal terminal on the shielding sheet is located between two adjacent protruding portions 42. With such an arrangement, the grounding terminals on both sides of the signal terminal can contact the shielding sheet through the protruding portions 42, thereby forming a shielding structure around the signal terminal.

[0049] Taking the first signal terminal 210 as an example, the projection of the first signal terminal 210 on the first shielding sheet 410 is located between two adjacent protrusions 42, and the two adjacent protrusions 42 are in contact with two first grounding terminals 310 respectively adjacent to the first signal terminal 210. The two protrusions 42 and the two first grounding terminals 310 form a C-shaped structure around the first signal terminal 210, which shields the external electromagnetic field and improves the transmission performance of the first signal terminal 210. The second signal terminal 220 is similar to the first signal terminal 210 and will not be elaborated here. The differential signal pair composed of the first signal terminal 210 and the second signal terminal 220 forms a shielding structure through the grounding terminal assembly 30 and the lap contact between the protrusion 42 of the shielding sheet and the grounding terminal assembly 30 around the differential signal pair, achieving the effect of stable signal transmission. In this embodiment, the shielding sheet is provided with protrusions 42 corresponding to each grounding terminal, so that each grounding terminal can be connected to the shielding sheet through the protrusion 42.

[0050] Please refer to again Figure 5 , in this embodiment, the protrusion 42 is a boss. Taking the first shielding sheet 410 as an example, the second surface of the first shielding sheet 410 is recessed towards the first surface, forming a protrusion higher than the first surface, that is, the protrusion 42. From Figure 5 it can be seen that the cross-sectional shape of the protrusion 42 is U-shaped, and the surface in contact with the first grounding terminal 310 is a flat surface, which can ensure full contact between the first shielding sheet 410 and the first grounding terminal 310 and avoid missed connection. In other embodiments, the surface of the protrusion 42 in contact with the grounding terminal can also be an arc surface, which can also achieve the lap contact between the shielding sheet and the grounding terminal. The contact method between the second shielding sheet 420 and the second grounding terminal 320 is the same as that between the first shielding sheet 410 and the first grounding terminal 310 and will not be elaborated here.

[0051] Furthermore, in this embodiment, the grounding terminal includes a first end, a second end, and a transmission section located between the first end and the second end, and the extending direction of the boss on the shielding sheet corresponds to the transmission section of the grounding terminal. The transmission section corresponds to the transmission path of the grounding terminal and is exposed and arranged on the insulating frame assembly 10. For example, the first end and the second end of the grounding terminal are fixed in the insulating block assembly by plastic molding, and the transmission section between the first end and the second end is partially or completely exposed on the insulating frame assembly 10, that is, the transmission section of the grounding terminal is not completely covered by the insulating frame assembly 10, forming an exposed part for the shielding assembly 40 to contact. The size of the transmission section exposed from the insulating frame assembly can be selected according to actual needs and is not limited here. In this embodiment, the grounding terminal is a strip-shaped structure, and its first end, second end, and part of the transmission section are injection-molded in the insulating frame assembly 10 to fix the grounding terminal assembly 30, and the rest of the transmission section is exposed from the insulating frame assembly 10.

[0052] Correspondingly, the extension of the boss on the shielding sheet corresponds to the transmission section of the grounding terminal, and the extension length of the boss matches the length of the transmission section of the grounding terminal. For example, when the length of the transmission section is longer, the length of the boss is also longer; when the length of the transmission section is shorter, the length of the boss is correspondingly shorter. In addition, the boss can be a continuous strip structure corresponding to the transmission section, or can include multiple segments. For example, a boss can be composed of multiple discontinuous strip structures, so as to reserve space for the assembly of the shielding sheet.

[0053] In other embodiments, the protrusion 42 is a bump. The number of the protrusions 42 is multiple, and the arrangement direction of the multiple bumps on the shielding sheet corresponds to the transmission path of the grounding terminal. When the shielding component 40 is installed on the insulating frame component 10, the shielding sheet can achieve lap contact with the grounding terminal through the bumps. In addition, the shape of the bumps is not limited, and can be columnar, strip-shaped, or conical. The number of the bumps can be selected according to actual needs and is not limited here.

[0054] As Figure 1 shown, the shielding component 40 includes a contact end and a mounting end. The first end of the grounding terminal extends out of the insulating frame component 10 and is connected to the contact end. Corresponding to the contact end and the mounting end of the signal terminal component 20, the contact end of the shielding sheet is also used to connect to other connectors, and the mounting end is used to connect to a PCB board or other components. Taking the first shielding sheet 410 as an example, the contact end of the first shielding sheet 410 is provided near the first end of the grounding terminal, and the grounding terminal is connected to the grounding terminal through the contact end of the first shielding sheet 410, so as to achieve a better grounding effect when connecting to other connectors. The connection method between the first shielding sheet 410 and the first end of the grounding terminal can be crimping. For example, when manufacturing the connector terminal, the first end of the grounding terminal extends out of one side of the insulating frame component 10. After the shielding sheet is installed on the insulating frame component 10, pressure is applied to press the contact end of the shielding sheet onto the first end to complete the connection between the grounding terminal and the contact end of the shielding sheet.

[0055] The shielding component 40 includes two shielding sheets, which are respectively located on opposite sides of the insulating frame component 10 and are connected to the insulating frame component 10. In this embodiment, mounting posts are provided on the side of the insulating frame component 10 facing the shielding sheet, and the shielding sheet is provided with positioning holes corresponding to the mounting posts. During installation, the mounting posts pass through the positioning holes to achieve the connection between the insulating frame component 10 and the shielding component 40. The setting positions and numbers of the positioning posts and the positioning holes can be selected according to actual needs and are not limited here. In other embodiments, the shielding component 40 can also be connected to the insulating frame component 10 by means of snap-fitting.

[0056] In this embodiment, two shielding sheets are connected by a connecting strip. The two shielding sheets are arranged on opposite sides of the insulating frame assembly 10, such that there is a certain distance between them, and the length of the connecting strip is slightly greater than or equal to the distance between them. Both ends of the connecting strip are respectively connected to the two shielding sheets. The material of the connecting strip can be the same as that of the shielding sheet, and both have electrical conductivity. The connecting strip and the shielding sheet can be connected by welding or integrally formed. In addition, the shape and the setting method of the connecting strip can be selected according to actual needs. For example, it can be strip-shaped and arranged at the edge near the contact end of the shielding sheet, and so on.

[0057] In the above embodiments, the shielding component 40 protrudes towards the grounding terminal component 30 to form a protrusion 42, and contacts the grounding terminal through the shielding sheet, and then jointly acts with the grounding terminals on both sides of the signal terminal to form a semi-closed structure around the signal terminal, improving the electromagnetic shielding effect and the transmission performance of the signal terminal.

[0058] In other embodiments, a protrusion can also be provided on the side of the grounding terminal facing the shielding sheet, and the semi-closed structure can also be formed around the signal terminal by contacting the shielding sheet through the protrusion. In this embodiment, the shielding sheet is a flat plate structure, and a plurality of convex columns are provided on the surface of the grounding terminal facing the shielding sheet. The convex columns are higher than the surface of the grounding terminal. When the shielding sheet is installed on the insulating frame assembly 10, the convex columns contact the shielding sheet. Convex columns are provided on the grounding terminals on both sides of each signal terminal to achieve the anti-interference effect on the signal terminal.

[0059] The above connector terminals can be used in high-speed connectors. In this embodiment, a connector includes a plurality of the above connector terminals, and the plurality of connector terminals are stacked in sequence to form a connector, and the connector has a good electromagnetic shielding effect and a high transmission performance.

[0060] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0061] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
