The present disclosure relates to a connector; in particular, to a high speed connector and a transmission module thereof.
A conventional high speed connector is provided with a grounding sheet to connect with a plurality of grounding terminals thereof, thereby reducing insertion loss and crosstalk. A conventional grounding sheet has a sheet portion and a plurality of elastic arms integrally extended from the sheet portion. The elastic arms are formed in a cantilever beam mode, and are integrally formed with the sheet portion by using a punching process. However, the conventional grounding sheet does not have a good structural strength, and is not formed with any portion to shield the differential signal terminals of the conventional high speed connector. Thus, the performance of the conventional high speed connector cannot be increased by improving the conventional grounding sheet.
The present disclosure provides a high speed connector and a transmission module thereof to solve the drawbacks associated with conventional high speed connectors.
The present disclosure discloses a high speed connector including a housing, an insulating core, a plurality of first conductive terminals, a plurality of second conductive terminals, and a shielding member. The insulating core is inserted into the housing. The first conductive terminals are fixed on the insulating core and are arranged in one row parallel to a width direction. Each of the first conductive terminals is substantially arranged in the housing. The first conductive terminals include two differential signal terminals and two grounding terminals, and the two grounding terminals are respectively arranged at two opposite outer sides of the two differential signal terminals. The second conductive terminals are fixed on the insulating core and are arranged in one row parallel to the width direction. Each of the second conductive terminals is substantially arranged in the housing, and a length of each of the second conductive terminals is less than or equal to that of each of the first conductive terminals. The shielding member includes a substrate and a metallic coating layer. The substrate is detachably fastened to the housing. The metallic coating layer is coated on the substrate, and is abutted against the two grounding terminals to establish an electrical connection between the two grounding terminals. The metallic coating layer is arranged at the two opposite outer sides of the two differential signal terminals. The metallic coating layer is configured to shield the two differential signal terminals in the width direction.
The present disclosure also discloses a transmission module of a high speed connector. The transmission module includes an insulating core, two differential signal terminals and two grounding terminals, and a shielding member. The differential signal terminals and the two grounding terminals are fixed on the insulating core and are arranged in one row parallel to a width direction. The two grounding terminals are respectively arranged at two opposite outer sides of the two differential signal terminals. The shielding member includes a substrate and a metallic coating layer. The metallic coating layer is coated on the substrate, and is abutted against the two grounding terminals to establish an electrical connection between the two grounding terminals. The metallic coating layer is arranged at the two opposite outer sides of the two differential signal terminals. The metallic coating layer is configured to shield the two differential signal terminals in the width direction.
In summary, for the high speed connector (or the transmission module) in the present disclosure, the shielding member has a shielding function for the differential signal terminals by using the metallic coating layer, so that the quality and the performance of signal transmission of the high speed connector (or the transmission module) can be effectively improved. Moreover, for the high speed connector (or the transmission module) in the present disclosure, the substrate having a better structural strength can be configured to support the metallic coating layer by coating the metallic coating layer on the substrate, so that the metallic coating layer is not easily deformed.

Reference is made to
In order to clearly describe the present embodiment, the housing 1 defines a width direction W, a longitudinal direction L, and a height direction H, the latter three of which are perpendicular to each other. As shown in
As shown in
In addition, the insulating core 2 in the present embodiment adapts the first plastic core 21 and the second plastic core 22 inserted into the first plastic core 21, but the present disclosure is not limited thereto. That is to say, the insulating core 2 can be adjusted according to practical needs. In other embodiments of the present disclosure, the insulating core 2 can be integrally formed as one piece.
As shown in
Moreover, as shown in
Thus, the externally connecting portions 311 are embedded in the insulating core 2 (i.e., the first plastic core 21) having a higher structural strength, so that when each of the externally connecting portions 311 is abutted against the other component (i.e., the shielding member 5), the insulating core 2 can support each of the externally connecting portions 311 to prevent a deformation from occurring, thereby maintaining a stable connection between each of the externally connecting portions 311 and the abutted component.
As shown in
Specifically, a length of each of the second embedded segments 41 is equal to that of each of the first embedded segments 31, a length of each of the second contacting segments 42 is equal to that of each of the first contacting segments 32, and a length of each of the second fixing segments 43 is less than that of each of the second contacting segments 33.
In other words, as shown in
As shown in
In should be noted that the substrate 51 in the present embodiment is an LDS plastic. That is to say, the substrate 51 is a portion of the LDS shielding member 5, which is not implemented in the laser structuring and activation process and the chemically coating process, so that the substrate 51 still has the insulating property. However, in other embodiments of the present disclosure, the substrate 51 can be a general plastic, which is not used in the LDS process. Moreover, in the present embodiment, a thickness of the substrate 51 in the width direction W is preferably more than that of the metallic coating layer 52, but the present disclosure is not limited thereto.
The substrate 51 is detachably fastened to the housing 1. The substrate 51 in the present embodiment is integrally formed as one piece, and includes a base portion 511, a plurality of partitions 512, a plurality of protruding portions 513, and two hooks 514. The base portion 511 has a substantially plate-like structure. Each of the partitions 512 having a plate-like structure is perpendicularly connected to a bottom surface of the base portion 511. The protruding portions 513 are connected to a front edge of the base portion 511 and/or the partitions 512. The two hooks 514 are respectively connected to two opposite sides of the base portion 511.
The metallic coating layer 52 includes a plurality of shielding portions 521, a plurality of abutting portions 522 respectively arranged adjacent to the shielding portions 521, and a bridging portion 523 configured to establish an electrical connection between the shielding portions 521 and the abutting portions 522. The shielding portions 521 are respectively coated on the partitions 512, and the abutting portions 522 are respectively coated on the protruding portions 513. The bridging portion 523 is coated on the base portion 511 and is connected to the shielding portions 521 and the abutting portions 522. It should be noted that the metallic shielding layer 52 in the present embodiment is arranged in a concave structure 515 of the substrate 51, but the present disclosure is not limited thereto.
The substrate 51 is fastened to the housing 1 by using the two hooks 514 to respectively buckle with the two positioning sheets 12. The partitions 512 respectively correspond in position to the grounding terminals 3G. The protruding portions 513 of the substrate 51 are respectively arranged in the notches 212 of the first plastic core 21, and the abutting portions 522 are respectively abutted against the externally connecting portions 311 of the grounding terminals 3G. Accordingly, the abutting portions 522 are coated on the protruding portions 513 having a higher structural strength, so that when the abutting portions 522 are respectively abutted against the externally connecting portions 311, the protruding portions 513 can be used to respectively support the abutting portions 522 to prevent a deformation, thereby maintaining a stable connection between each of the abutting portions 522 and the abutted externally connecting portion 311.
Moreover, as the differential signal terminals 3S and the grounding terminals 3G in the present embodiment are arranged in the bilateral symmetry, and the shielding member 5 is a mirror symmetry structure, the following description just discloses the structure of two differential signal terminals 3S shown in the right side of
Specifically, as shown in
Moreover, the two shielding portions 521 of the metallic coating layer 52 are respectively arranged at the two opposite outer sides of the two differential signal terminals 3S, and the metallic coating layer 52 is configured to shield the two differential signal terminals 3S in the width direction W. The two shielding portions 521 of the metallic coating layer 52 are configured to shield at least 25% of each of the first fixing segments 33 of the two differential signal terminals 3S in the width direction W, and the at least 25% of each of the first fixing segments 33 of the two differential signal terminals 3S is arranged adjacent to the insulating core 2. Preferably, the two shielding portions 521 of the metallic coating layer 52 are configured to shield entirely a portion of each of the two differential signal terminals 3S, which is arranged between the insulating core 2 and the bending corner 331 thereof, in the width direction W, but the present disclosure is not limited thereto.
Thus, the shielding member 5 have a shielding function for the differential signal terminals 3S by using the metallic coating layer 52, so that the quality and the performance of signal transmission of the high speed connector 100 in the present embodiment can be effectively improved.
It should be noted that each of the shielding portions 521 in the present embodiment is coated on a surface of the partition 512 being adjacent to the grounding terminal 3G, so that the shielding member 5 can be applied to a condition, that is any two adjacent of the first conductive terminals 3 provided with a smaller gap there-between, for preventing each of the shielding portions 521 from contacting the adjacent differential signal terminal 3S, but the present disclosure is not limited thereto. In other embodiments of the present disclosure, when any two adjacent of the first conductive terminals 3 are provided with a large gap there-between, two opposite surfaces of the partition 512 each can be coated with one shielding portion 521.
In addition, the insulating core 2 (i.e., the first plastic core 21), the first conductive terminals 3 (i.e., the two differential signal terminals 3S and the grounding terminals 3G shown in the left side of
In summary, for the high speed connector (or the transmission module) in the present disclosure, the shielding member has a shielding function for the differential signal terminals by using the metallic coating layer, so that the quality and the performance of signal transmission of the high speed connector (or the transmission module) can be effectively improved.
Moreover, the substrate having a better structural strength can be configured to support the metallic coating layer by coating the metallic coating layer on the substrate, so that the metallic coating layer is not easily deformed.
Specifically, the externally connecting portions are embedded in the insulating core (i.e., the first plastic core) having a higher structural strength, so that the insulating core can support each of the externally connecting portions. The abutting portions are coated on the protruding portions having a higher structural strength, so that the protruding portions can respectively support the abutting portions. Accordingly, when the abutting portions are respectively abutted against the externally connecting portions, the abutting portions and the externally connecting portions are not easily deformed, thereby maintaining a stable connection between each of the abutting portions and the abutted externally connecting portion.

All changes, alterations, or modifications conveniently considered by those skilled in the art are deemed to be encompassed within the scope of the present disclosure delineated by the following claims.
