As shown in fig. 1 to 3, the present embodiment discloses a high-speed connector 100, and the high-speed connector 100 of the present embodiment is exemplified by a right-angle connector (RIGHT ANGLE connectors), but the present invention is not limited thereto. That is, the high-speed connector 100 of the present invention may also be a vertical connector (vertical connector). The high-speed connector 100 includes a housing 1, an insulating rubber core 2 inserted in the housing 1, a plurality of first conductive terminals 3 and a plurality of second conductive terminals 4 fixed on the insulating rubber core 2, and a first shielding member 5 and a second shielding member 6 mounted on the insulating rubber core 2 (and/or the housing 1). In addition, in other embodiments of the present invention, which are not shown, the high-speed connector 100 may also be provided with a metal shell outside the housing 1 according to the requirements of the designer. The following will describe each component of the high-speed connector 100, and then describe the connection relationship between the components at appropriate times.
As shown in fig. 2 to 5, for the convenience of description of the present embodiment, the housing 1 defines a width direction W, a length direction L, and a height direction H, which are perpendicular to each other. The housing 1 has a main body 11 and two positioning pieces 12 extending from opposite sides of the rear end of the main body 11. Wherein, a plugging channel 111 and two rows of terminal slots 112 connected to the plugging channel 111 are formed in the body 11, and the two rows of terminal slots 112 are respectively located above and below the plugging channel 111, and each row of terminal slots 112 is arranged along the width direction W of the housing 1. The front end of the body 11 is formed with a socket 113, and the end of the body 11 is formed with a mounting groove 114, and the socket 113 and the mounting groove 114 are respectively located at the front side and the rear side of the socket 111 and are communicated with the socket 111.
As shown in fig. 2 to 5, the insulating rubber core 2 is inserted into the housing 1, and the insulating rubber core 2 of the present embodiment is inserted into the mounting groove 114 of the housing 1 to be used as a boundary of the plugging channel 111, but is not limited thereto. The insulating rubber core 2 includes a first rubber core 21 and a second rubber core 22, wherein the first rubber core 21 is formed with a plurality of concave-convex structures 211, the second rubber core 22 is formed with a plurality of matching structures 221, and the first rubber core 21 is detachably inserted into the plurality of matching structures 221 through the plurality of concave-convex structures 211 and is fixed on the second rubber core 22.
In addition, although the first and second cores 21 and 22 assembled with each other are described in the insulating core 2 of the present embodiment, the structure of the insulating core 2 may be changed according to the needs of the designer in practical application, and is not limited to the present embodiment. For example, in the embodiment of the invention not shown, the insulating rubber core 2 may also be of one-piece construction formed integrally.
As shown in fig. 2 and 4, the plurality of first conductive terminals 3 are arranged in the width direction W and fixed to the first rubber core 21, and the plurality of first conductive terminals 3 are substantially located in the housing 1. Each first conductive terminal 3 has a first embedded section 31 embedded and fixed in the insulating rubber core 2 (first rubber core 21), a first contact section 32 extending from the first embedded section 31 toward the plug-in port 113, and a first mounting section 33 extending from the first embedded section 31 toward a direction away from the plug-in port 113. That is, the plurality of first contact sections 32 are located in the upper row of terminal grooves 112 of the body 11, and a portion of each first contact section 32 is located in the plugging channel 111, and the first mounting section 33 is located substantially between the two positioning tabs 12. In more detail, each first mounting section 33 is formed with a first turning angle 331 of substantially 90 degrees after extending in the length direction L from its first embedded section 31.
In other words, as shown in fig. 2, 6, and 7, when the functions or applications of the first conductive terminals 3 are differentiated, the plurality of first conductive terminals 3 include a plurality of pairs of first differential signal terminals 3S and a plurality of first ground terminals 3G, each pair of first differential signal terminals 3S is located between two of the first ground terminals 3G, and the plurality of pairs of first differential signal terminals 3S and the plurality of first ground terminals 3G are arranged substantially in a bilateral symmetry manner in the present embodiment. The insulating rubber core 2 (e.g. the first rubber core 21) is formed with a plurality of first notches 212 (e.g. fig. 2 or 6), and portions of the plurality of first ground terminals 3G (e.g. rear end portions of the first embedded sections 31) are exposed from the plurality of first notches 212 to the outside of the insulating rubber core 2, and are defined as first external connection portions 311.
Therefore, since the first external connection portion 311 is embedded in the insulating rubber core 2 (e.g., the first rubber core 21) with high structural strength, the insulating rubber core 2 can effectively support the first external connection portion 311 of the first ground terminal 3G, so that when the first external connection portion 311 is abutted against other components (e.g., the first shielding member 5), the first external connection portion 311 is not easy to deform, and a stable connection relationship can be maintained between the first external connection portion 311 and the abutted components.
As shown in fig. 2 and 4, the plurality of second conductive terminals 4 are arranged in the above-mentioned width direction W and fixed to the second rubber core 22, and the plurality of second conductive terminals 4 are located substantially within the housing 1, and the length of each second conductive terminal 4 is not greater than the length of each first conductive terminal 3. Each second conductive terminal 4 has a second embedded section 41 embedded and fixed in the insulating rubber core 2 (second rubber core 22), a second contact section 42 extending from the second embedded section 41 toward the plug-in port 113, and a second mounting section 43 extending from the second embedded section 41 toward a direction away from the plug-in port 113. That is, the plurality of second contact sections 42 are located in the lower row of terminal grooves 112 of the body 11, and a part of each of the second contact sections 42 is located in the plugging passage 111, and the second mounting section 43 is located substantially between the two positioning pieces 12. In more detail, each second mounting section 43 is formed with a second turning angle 431 of substantially 90 degrees after protruding the insulating rubber core 2 (second rubber core 22) from its second embedding section 41.
Further, the lengths of the second embedded section 41 and the second contact section 42 of each second conductive terminal 4 in the present embodiment are substantially equal to the lengths of the first embedded section 31 and the first contact section 32 of each first conductive terminal 3, and the length of the second mounting section 43 of each second conductive terminal 4 is smaller than the length of the first mounting section 33 of each first conductive terminal 3.
In other words, as shown in fig. 2,3, 8, and 9, when the functions or applications of the second conductive terminals 4 are differentiated, the plurality of second conductive terminals 4 include a plurality of pairs of second differential signal terminals 4S and a plurality of second ground terminals 4G, each pair of second differential signal terminals 4S is located between two of the second ground terminals 4G, and the plurality of pairs of second differential signal terminals 4S and the plurality of second ground terminals 4G are arranged in a substantially bilateral symmetry manner in the present embodiment. The insulating rubber core 2 (e.g. the second rubber core 22) is formed with a plurality of second notches 222 (e.g. fig. 3 or 9), and portions of the second ground terminals 4G (e.g. front end portions of the second embedded sections 41) are exposed from the second notches 222 to the outside of the insulating rubber core 2, and are defined as second external portions 411.
Therefore, since the second external connection portion 411 is embedded in the insulating rubber core 2 (e.g., the second rubber core 22) with high structural strength, the insulating rubber core 2 can effectively support the second external connection portion 411 of the second ground terminal 4G, so that when the second external connection portion 411 abuts against other components (e.g., the second shielding member 6), the second external connection portion 411 is not easy to deform, and a stable connection relationship can be maintained between the second external connection portion 411 and the abutted components.
As shown in fig. 2, the first shielding member 5 and the second shielding member 6 are further defined as a Laser Direct Structuring (LDS) shielding member 5, 6 in the present embodiment, but the invention is not limited thereto. As shown in fig. 10 to 12, the first shielding member 5 includes a first substrate 51 and a first metal plating layer 52 plated on the surface of the first substrate 51 (the first metal plating layer 52 may be a single structure integrally connected or a plurality of separate components). The first base material 51 is integrally formed in this embodiment, and the first metal plating layer 52 contacts at least two first ground terminals 3G of the plurality of first conductive terminals 3, so that the at least two first ground terminals 3G can be electrically connected to each other through the first metal plating layer 52. Therefore, the first shielding member 5 is plated on the first substrate 51 with high structural strength through the first metal plating layer 52, so that the first substrate 51 can support the first metal plating layer 52, and the first metal plating layer 52 is less prone to deformation.
Furthermore, as shown in fig. 13 to 15, the second shielding member 6 includes a second substrate 61 and a second metal plating layer 62 plated on the surface of the second substrate 61 (the second metal plating layer 62 may be a single structure integrally connected or a plurality of separate components). The second substrate 61 is integrally formed in this embodiment, and the second metal plating layer 62 contacts at least two second ground terminals 4G of the plurality of second conductive terminals 4, so that the at least two second ground terminals 4G can be electrically connected to each other through the second metal plating layer 62. Thereby, the second shielding member 6 is plated on the second substrate 61 with higher structural strength through the second metal plating layer 62, so that the second substrate 61 can support the second metal plating layer 62, and the second metal plating layer 62 is less prone to deformation.
It should be noted that, in the present embodiment, the first substrate 51 and the second substrate 61 refer to LDS plastics, that is, the portions of the LDS shields 5, 6 not subjected to laser engraving (Laser Structuring and Activation) and electroless plating, so that the first substrate 51 and the second substrate 61 have insulating properties. However, in the embodiment of the invention not shown, the first substrate 51 and the second substrate 61 may also be common plastics (i.e. plastics not used in LDS technology). Furthermore, the thicknesses of the first substrate 51 and the second substrate 61 in the width direction W are preferably greater than the thicknesses of the first metal plating layer 52 and the second metal plating layer 62 in the present embodiment, but the present invention is not limited thereto.
As shown in fig. 4, 10-12, the first substrate 51 is detachably assembled to the first core 21 (and/or the housing 1), and the first substrate 51 of the present embodiment includes a first base 511, a plurality of first ribs 512, and two hooks 513. The first base 511 is a substantially flat plate-shaped integral structure, each first rib 512 is connected to the bottom surface of the first base 511, each first rib 512 includes a first protrusion 5121 protruding from the front edge of the first base 511, and two hooks 513 are respectively connected to opposite side edges of the first base 511. Wherein, any two adjacent first ribs 512 and the first base 511 therebetween are jointly formed with a first groove 514 facing the corresponding two first differential signal terminals 3S.
The first metal plating layer 52 includes a plurality of first shielding portions 521 and a plurality of first abutting portions 522, and opposite sides of each first shielding portion 521 are respectively connected to at least two first abutting portions 522. The first shielding portions 521 are respectively plated on the inner sidewalls of the first grooves 514, and the first abutting portions 522 are respectively plated on the bottom surfaces of the first ribs 512 (including the first protruding portions 5121).
The two hooks 513 of the first base material 51 are respectively engaged with the two positioning plates 12 of the housing 1, and the positions of the plurality of first ribs 512 respectively correspond to the plurality of first grounding terminals 3G, and the plurality of first protruding portions 5121 of the first base material 51 are respectively accommodated in the plurality of first notches 212 of the first rubber core 21, so that the plurality of first abutting portions 522 respectively abut against the first external connection portions 311 of the plurality of first grounding terminals 3G. Therefore, since the first contact portion 522 is plated on the first protruding portion 5121 with high structural strength, the first protruding portion 5121 can support the first contact portion 522 of the first metal plating layer 52, so that when the first contact portion 522 and the first external portion 311 contact each other, the first contact portion 522 is not easy to deform, and a stable connection relationship between the first contact portion 522 and the first external portion 311 can be maintained.
Further, since the pairs of first differential signal terminals 3S and the first ground terminals 3G of the first conductive terminals 3 are arranged in a substantially laterally symmetrical manner in the present embodiment, and the first shielding members 5 are also configured in a substantially laterally symmetrical manner, the following description will mainly describe the connection relationship between the first conductive terminals 3 and the first shielding members 5 with respect to the leftmost two first differential signal terminals 3S and the two first ground terminals 3G of fig. 6 or 11, and the configuration of the first shielding members 5 corresponding to each other in the height direction H (e.g., the first shielding member 5 portion shown in fig. 12) for the convenience of understanding the present embodiment.
In more detail, as shown in fig. 6, 7, 11 and 12, the two first ribs 512 are respectively located above the two first ground terminals 3G, the first shielding portion 521 is plated on the inner side wall of the first groove 514 between the two first ribs 512, and the two first abutting portions 522 are respectively plated on the bottom surfaces of the two first ribs 512 (including the first protruding portions 5121), so that when the two first protruding portions 5121 are respectively accommodated in the corresponding two first notches 212, the two first abutting portions 522 can respectively abut against the first external connecting portions 311 of the two first ground terminals 3G.
Further, (the first shielding portion 521 of) the first metal plating layer 52 is located above the two first differential signal terminals 3S in the height direction H, so that the first metal plating layer 52 can shield the two first differential signal terminals 3S in the height direction H. Wherein (the first shielding part 521 of) the first metallization layer 5 is projected forward in the height direction H toward the first projection area formed by the two first differential signal terminals 3S, which covers at least 20% of the first differential signal terminals 3S, as shown in fig. 5, 6, and 7. Further, as shown in fig. 5, the first projection area can cover at least 90% of the first mounting section 33 of the first differential signal terminal 3S, so that (the first shielding portion 521 of) the first metal plating layer 5 can substantially completely shield the portion of the first differential signal terminal 3S between the insulating rubber core 2 and the first inflection angle 331 above the first metal plating layer along the height direction H, but the invention is not limited thereto.

Therefore, since the second contact portion 622 is plated on the second protruding portion 6121 with high structural strength, the second protruding portion 6121 can support the second contact portion 622 of the second metal plating layer 62, so that when the second contact portion 622 and the second external contact portion 411 are abutted against each other, the second contact portion 622 is not easy to deform, and a stable connection relationship between the second contact portion 622 and the second external contact portion 411 can be maintained.

Further, (the second shielding portion 621 of) the second metal plating layer 62 is located below the two second differential signal terminals 4S in the height direction H, so that the second metal plating layer 62 can shield the two second differential signal terminals 4S in the height direction H. Wherein (the second shielding portion 621 of) the second metal plating layer 6 is projected forward in the height direction H toward the second projection area formed by the two second differential signal terminals 4S, which covers at least 20% of the second differential signal terminals 4S, as shown in fig. 5, 8, and 9. Further, as shown in fig. 5, the second projection area can cover at least 50% of the second embedded segments 41 of the second differential signal terminals 4S, so that (the second shielding portion 621 of) the second metal plating layer 6 can substantially completely shield the second embedded segments 41 of the corresponding second differential signal terminals 4S under the height direction H, but the invention is not limited thereto.

That is, in the embodiment of the present invention, the transmission module may be applied to other high-speed connectors.
In addition, the structures of the first shielding member 5 and the second shielding member 6 in the present embodiment can be adjusted according to the needs of the designer, and the present invention is not limited thereto.

[ Technical efficacy of the embodiment of the invention ]
In summary, in the high-speed connector and the transmission module thereof disclosed in the embodiments of the present invention, the first metal plating layer and the second metal plating layer of the first shielding member and the second shielding member respectively generate shielding effects on the first differential signal terminal and the second differential signal terminal in the height direction, so as to effectively improve the signal transmission quality and performance of the high-speed connector (or the transmission module).
In addition, the first shielding piece and the second shielding piece are respectively plated on the first base material and the second base material with high structural strength through the first metal plating layer and the second metal plating layer, so that the first metal plating layer and the second metal plating layer are not easy to deform.
For example, the first external connection part is embedded in an insulating rubber core (such as a first rubber core) with higher structural strength, so that the insulating rubber core can support the first external connection part of the first grounding terminal; the first abutting part is plated on the first protruding part with high structural strength, so that the first protruding part can support the first abutting part of the first metal plating layer. Therefore, when the first abutting part and the first external connection part are abutted against each other, the first abutting part and the first external connection part are not easy to deform, so that a stable connection relationship can be maintained between the first abutting part and the first external connection part. Similarly, in the present embodiment, a stable connection relationship can be maintained between the second contact portion and the second external portion.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, but all equivalent changes and modifications according to the claims of the present invention shall fall within the scope of the claims.
