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).

As shown in fig. 2 to 4, 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 4, 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 part of each first contact section 32 is located in the plugging channel 111, and the first mounting section 33 is located between the two positioning pieces 12. In more detail, each first mounting section 33 is formed with a turn angle 331 after extending from its first embedded section 31 in a length direction L perpendicular to the width direction W.
In other words, as shown in fig. 5 to 9, when the functions or the uses 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, and the plurality of pairs of first differential signal terminals 3S and the plurality of first ground terminals 3G are arranged in a substantially bilateral symmetry in the present embodiment. The insulating rubber core 2 (e.g. the first rubber core 21) is formed with a plurality of notches 212 (e.g. fig. 2), 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 notches 212 to the outside of the insulating rubber core 2, respectively, and are defined as an external connection portion 311.
Therefore, since the 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 support the external connection portion 311 of the first ground terminal 3G, so that when the external connection portion 311 is abutted against other components (e.g., the first shielding member 5), the external connection portion 311 is not easy to deform, and a stable connection relationship can be maintained between the 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.

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. 7 and 9, when the functions or the usages 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, and the arrangement of the second differential signal terminals 4S and the second ground terminals 4G in the plurality of second conductive terminals 4 is substantially identical to the arrangement of the first differential signal terminals 3S and the first ground terminals 3G in the plurality of first conductive terminals 3.
As shown in fig. 2, 4, 10, and 11, the first shielding member 5 is formed by injection molding in the present embodiment, that is, the first shielding member 5 of the present embodiment is formed by excluding other modes, for example: laser Direct Structuring (LDS). The first shielding member 5 includes a first substrate 51 and two first metal sheets 52 embedded on the surface of the first substrate 51 and separated from each other, and for convenience of description, only one of the first metal sheets 52 is described below.
The first metal sheet 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 sheet 52. Therefore, the first shielding member 5 is embedded in the first substrate 51 with higher structural strength through the first metal sheet 52, so that the first substrate 51 can support the first metal sheet 52, and the first metal sheet 52 is less prone to deformation.
In the present embodiment, the first substrate 51 is plastic, so the first substrate 51 has insulation properties. Furthermore, the thickness of the first substrate 51 in the width direction W is preferably greater than the thickness of the first metal sheet 52 in the present embodiment, but the present invention is not limited thereto.
The first substrate 51 is detachably assembled to the housing 1, and the first substrate 51 of the present embodiment includes a base 511, a plurality of isolation portions 512, a plurality of protruding portions 513, and two hooks 514. The base 511 is a substantially flat plate-shaped integral structure, each of the spacers 512 is substantially flat plate-shaped and is vertically connected to the bottom surface of the base 511, the plurality of protrusions 513 are connected to the front edge of the base 511 and/or the plurality of spacers 512, and the two hooks 514 are respectively connected to opposite side edges of the base 511.
The first metal sheet 52 includes a plurality of shielding portions 521, a plurality of contact portions 522 adjacent to the plurality of shielding portions 521, and a connecting portion 523, and the connecting portion 523 electrically connects the plurality of shielding portions 521 and the plurality of contact portions 522. Wherein the shielding parts 521 are respectively embedded in the isolating parts 512, the abutting parts 522 are respectively embedded in the protruding parts 513, and the connecting part 523 is embedded in the base part 511 and connects the shielding parts 521 and the abutting parts 522. It should be noted that, in the present embodiment, the first metal sheet 52 is located in a groove-like structure 515 of the first substrate 51, but the present invention is not limited thereto.
The two hooks 514 of the first substrate 51 are respectively engaged with the two positioning plates 12 of the housing 1, and the positions of the plurality of isolation portions 512 respectively correspond to the plurality of first grounding terminals 3G, and the plurality of protruding portions 513 of the first substrate 51 are respectively accommodated in the plurality of notches 212 of the first glue core 21, so that the plurality of abutting portions 522 respectively abut against the external connection portions 311 of the plurality of first grounding terminals 3G. Accordingly, since the abutting portion 522 is embedded in the protruding portion 513 having high structural strength, the protruding portion 513 can support the abutting portion 522 of the first metal sheet 52, so that the abutting portion 522 is not easily deformed when the abutting portion 522 and the external portion 311 abut against each other, and a stable connection relationship between the abutting portion 522 and the external portion 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 arrangement in the present embodiment and the first shields 5 are also configured in a substantially laterally symmetrical manner, the following description will mainly refer to the connection relationship between the first conductive terminals 3 and the first shields 5 with respect to the two first differential signal terminals 3S on the rightmost side in fig. 5 (or fig. 7), the two first ground terminals 3G respectively located on the opposite outer sides of the two first differential signal terminals 3S, and the related configuration of the first shields 5 (e.g., the plurality of isolation portions 512 in fig. 6 or fig. 8, and the first metal pieces 52 located at the plurality of isolation portions 512) for the convenience of understanding the present embodiment.
In more detail, as shown in fig. 4, 6 and 8, the two isolation portions 512 are respectively located above the two first ground terminals 3G, the two shielding portions 521 are respectively embedded on the surfaces of the two isolation portions 512, and the two abutting portions 522 are respectively embedded in the two protruding portions 513, so that when the two protruding portions 513 are respectively accommodated in the corresponding two notches 212, the two abutting portions 522 can respectively abut against the external connection portions 311 of the two first ground terminals 3G.
Furthermore, since each pair of first differential signal terminals 3S emits an electromagnetic field to the periphery thereof that may affect the other pairs of first differential signal terminals 3S during signal transmission, the first metal sheet 52 is disposed substantially at two outer sides (e.g., upper left and upper right) of the two first differential signal terminals 3S, so that the first metal sheet 52 can electromagnetically shield the two first differential signal terminals 3S in the width direction W. Wherein (the two shielding portions 521 of) the first metal piece can electromagnetically shield at least 25% of the first mounting section 33 of each first differential signal terminal 3S in the width direction W. Preferably, (two shielding parts 521 of) the first metal sheet can electromagnetically shield at least 80% of the portion between the insulating rubber core 2 and the turning angle 331 of each first differential signal terminal 3S in the width direction W, but the present invention is not limited thereto.
Therefore, the first shielding member 5 generates electromagnetic shielding effect on the first differential signal terminal 3S through the first metal sheet 52, so as to effectively improve the signal transmission quality and performance of the high-speed connector 100 of the embodiment.
It should be noted that, in the present embodiment, the shielding portion 521 is embedded in one surface of the isolation portion 512 for a small distance between any two first conductive terminals 3, but the present invention is not limited thereto. For example, in the embodiment of the invention not shown, the opposite surfaces of the isolation portion 512 may also be respectively plated with the shielding portions 521.
In addition, the insulating rubber core 2 (e.g., the first rubber core 21), the plurality of first conductive terminals 3 (e.g., the two first differential signal terminals 3S and the two first ground terminals 3G on the right side in fig. 7), and the first shielding member 5 (e.g., the first shielding member 5 corresponding to the two first differential signal terminals 3S and the two first ground terminals 3G) can be collectively referred to as a transmission module of the high-speed connector 100, and the components and the structure of the transmission module are not limited to the description in the embodiment. That is, in the embodiment of the present invention, the transmission module may be applied to other high-speed connectors.
In addition, referring to fig. 4, 9 and 12, the high-speed connector 100 of the present embodiment may further include a second shielding member 6 mounted on the housing 1, and the second shielding member 6 is formed by injection molding in the present embodiment, that is, the second shielding member 6 of the present embodiment excludes other structures, for example: laser direct shaping. The second shielding member 6 includes a second substrate 61 and two second metal sheets 62 embedded in the second substrate 61, and for convenience of description, only one of the second metal sheets 62 is described below.
The second metal sheet 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 sheet 62. Thereby, the second shielding member 6 is embedded in the second substrate 61 with higher structural strength through the second metal sheet 62, so that the second substrate 61 can support the second metal sheet 62, and the second metal sheet 62 is less prone to deformation.
In the present embodiment, the second substrate 61 is plastic, so the second substrate 61 has insulation properties. Furthermore, the thickness of the second substrate 61 in the width direction W is preferably greater than the thickness of the second metal sheet 62 in the present embodiment, but the present invention is not limited thereto.
The second substrate 61 is detachably assembled to the housing 1 and the insulating core 2, and the second metal sheet 62 includes a buried portion 621 and a plurality of connecting arms 622 extending from the buried portion 621. Wherein the embedded portion 621 is entirely embedded in the second substrate 61 and is located below the second embedded section 41 of the second conductive terminal 4 (or the second differential signal terminal 4S). Each connecting arm 622 is buried in the second substrate 61 and partially exposed outside the second substrate 61, so that the plurality of connecting arms 622 can respectively abut against the plurality of second ground terminals 4G in the plurality of second conductive terminals 4.
Thereby, the second shield 6 can electromagnetically shield the second differential signal terminal 4S among the second conductive terminals 4 below the height direction H with (the embedded portion 621 of) the metal piece 62.
In addition, the transmission module of the high-speed connector 100 in the present embodiment may further include the second rubber core 22, a plurality of second conductive terminals 4 (e.g., two second differential signal terminals 4S and two second ground terminals 4G at the right side in fig. 7), and the second shielding member 6 (e.g., the second shielding member 6 corresponding to the two second differential signal terminals 4S and the two second ground terminals 4G), but 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 sheet of the first shielding member generates electromagnetic shielding effect on the first differential signal terminal (of the first conductive terminal), 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 disclosed by the embodiment of the invention is embedded in the first base material with higher structural strength through the first metal sheet, so that the first base material can support the first metal sheet, and the first metal sheet is less prone to deformation.
Further, because the external connection part is embedded in the insulating rubber core (such as the first rubber core) with higher structural strength, the insulating rubber core can support the external connection part of the first grounding terminal; the abutting part is embedded in the protruding part with high structural strength, so that the protruding part can support the abutting part of the first metal sheet. Therefore, when the abutting part and the external part are abutted against each other, the abutting part and the external part are not easy to deform, so that a stable connection relationship can be maintained between the abutting part and the external part.
In addition, the high-speed connector of the present embodiment may further include a second shielding member mounted on the housing, and the second shielding member may be configured to electromagnetically shield the second differential signal terminals of the second conductive terminals with the embedded portions thereof below the height direction, so as to further effectively improve the signal transmission quality and performance of the high-speed connector.
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.
