[0022] The beneficial effects of the present application are:

[0023] 1. The present application provides a connector, which includes a first connection module. The first connection module includes signal terminals, ground terminals, a first plastic package, a second plastic package, and a tail plate. The signal terminals and the ground terminals are distributed at intervals to provide a good shielding and protection effect for the signals. The first plastic package fixes the signal terminals and the ground terminals. After the terminals are welded to the cable, they are protected and hidden in the second plastic package. The tail plate connects the ground terminals into an integrated body so that the ground terminals are electrically connected, thereby enhancing the shielding effect. Moreover, the tail plate can also support the welded end of the cable, avoiding the risk of loosening, instability, and even disconnection due to the lack of support and the suspension of the cable.

[0024] 2. The ground terminals of the present application are connected into an integrated body not only at the welding ends as described above, but also at the fixing parts. On the one hand, it enhances the structural stability and mechanical strength of the ground terminals in the mechanical structure design. On the other hand, it enhances the conduction effect of each contact end in the electrical conduction and shielding design, enabling each contact end to be fully conducted and thus improving the shielding effect.

[0025] 3. The ground terminals of the present application are cooperatively docked with the fixing posts on the first plastic package through fixing holes, thereby realizing the fixed connection between the ground terminals and the first plastic package, and enhancing the stability and reliability of the product.

[0026] 4. The tail plate of the present application can extend to the outside of the second plastic package and be electrically connected to the metal shell, thereby forming the conduction of the overall shielding of the product and enhancing the shielding effect of the product.

[0027] 5. The connector of the present application further includes a second connection module that is the same or similar to the first connection module in structure and function. After the two modules are correspondingly snapped together, the first bending piece and the second bending piece on the tail plate are docked, forming a ground connection between the two modules. And both modules are connected to the metal shell of the product through the snap pieces, further enhancing the electromagnetic interference resistance ability of the product and improving the overall shielding performance of the product.

[0028] 6. The connector of the present application is assembled from multiple modules. The structural design between the modules is reasonable and convenient for installation and cooperation, and at the same time, it also has good shielding performance. Description of the Drawings

[0042] This application provides a connector, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0043] As Figure 1-2 shown, in some embodiments of this application, a connector includes a first connection module 1; the first connection module 1 includes a plurality of ground terminals 2, a plurality of signal terminals 3, a first plastic package 4, and a second plastic package 5. The plurality of ground terminals 2 and the plurality of signal terminals 3 are both longitudinally elongated and arranged at intervals and staggered in the width direction; the specific arrangement manner of the ground terminals 2 and the signal terminals 3, for example, three or two signal terminals 3 are sandwiched between two ground terminals 2, can be adjusted according to actual requirements.

[0044] As Figure 2-3As shown, each grounding terminal 2 and each signal terminal 3 include a contact portion 6, a fixing portion 7, and a welding portion 8 along their longitudinal directions; the fixing portions 7 of the grounding terminals 2 and the fixing portions 7 of the signal terminals 3 are both encapsulated in the first encapsulation member 4; the contact portions 6 of the grounding terminals 2 and the contact portions 6 of the signal terminals 3 both extend out of the first side 9 of the first encapsulation member 4; the welding portions 8 of the grounding terminals 2 and the welding portions 8 of the signal terminals 3 both extend out of the second side 10 of the first encapsulation member 4 and are respectively welded to the cable 11; the second encapsulation member 5 is encapsulated at the welding joints of the welding portions 8 of the grounding terminals 2 and the signal terminals 3 and the cable 11; the contact portion 6 contacts the corresponding connecting member in the inserted socket to achieve signal transmission, the fixing portion 7 fixes the grounding terminal 2 and the signal terminal 3 to the first encapsulation member 4, thereby enhancing the stability and reliability of the product, and the welding portion is connected to the cable 11 to transmit the signal output from the above-mentioned socket to the next electrical component through the above-mentioned terminal and the cable 11 in sequence, thereby completing the connection function of the connector of the present application. As Figure 1-2 As shown, in some embodiments of the present application, the first side 9 and the second side 10 are respectively disposed opposite to both ends of the first encapsulation member 4, and the orientation of the first side 9 is adapted to the extending direction of the contact portion 6 of the above-mentioned terminal, and the second side 10 is disposed facing one side of the second encapsulation member 5.

[0045] As Figure 1 As shown, the first connection module 1 further includes a tail plate 12, the tail plate 12 extends parallel to the longitudinal direction of the grounding terminal 2 and is integrally connected to the welding portions 8 of all the grounding terminals 2, and provides a supporting force for the cable 11; the tail plate 12 connects the grounding terminals 2 into one body so that the grounding terminals 2 are electrically connected, thereby enhancing the shielding effect, and the tail plate 12 can also play a role in supporting the welding end of the cable 11, avoiding the risk of loosening, insecurity, and even falling off and disconnection that may be caused by the cable 11 being suspended due to lack of support.

[0046] As Figure 3 As shown, in some embodiments of the present application, the fixing portion 7 of the grounding terminal 2 is bent and extended and misaligned relative to the contact portion 6 and the welding portion 8 of the grounding terminal 2, and the fixing portion 7 of the grounding terminal 2 and the fixing portion 7 of the signal terminal 3 are misaligned in the thickness direction of the first encapsulation member 4. Such a design is beneficial to connecting the fixing portions 7 of the grounding terminals 2 inside the first encapsulation member 4 into one body, thereby enhancing the electrical connection effect between the grounding terminals 2, and further enhancing the shielding effect of the product.

[0047] As Figure 1 and Figure 4As shown, in some embodiments of the present application, the fixing portion 7 of the grounding terminal 2 is provided with a fixing hole 22, and the first plastic encapsulation member 4 is provided with a fixing post 23. The fixing post 23 is in mating connection with the fixing hole 22 to connect and fix the grounding terminal 2 and the first plastic encapsulation member 4. Such a design is beneficial to enhancing the fixing connection effect between the grounding terminal 2 and the first plastic encapsulation member 4, thereby enhancing the stability and reliability of the product.

[0048] As Figure 1-4 shown, in some embodiments of the present application, both sides of the tail plate 12 in the width direction extend out of the second plastic encapsulation member 5 and bend and extend along the thickness direction of the second plastic encapsulation member 5 to form a clamping piece 13; the connector further includes a first metal housing 14, and the first metal housing 14 is clamped with the clamping piece 13 to be connected and fixed to the first connection module 1, and the cable 11 extends out of the first metal housing 14; such a design enables the grounding terminal 2 in the first connection module 1 to be electrically connected to the first metal housing 14 through the tail plate 12 and the clamping piece 13 in sequence, thereby improving the overall electromagnetic interference resistance and shielding effect of the connector.

[0049] As Figure 1-4 shown, in some embodiments of the present application, the free end of the clamping piece 13 bends and extends towards both sides in the width direction of the second plastic encapsulation member 5. In some other embodiments, the free end of the clamping piece 13 can also bend and extend towards the thickness direction of the plastic encapsulation member 5. The specific bending direction can be appropriately adjusted, and the same effect of electrically connecting the grounding terminal 2 and the first metal housing 14 can be achieved.

[0050] As Figure 3 shown, in some embodiments of the present application, the side of the tail plate 12 away from the welding part bends and extends towards the thickness direction of the second plastic encapsulation member 5 to form a first bending piece 15, and the first bending piece 15 exposes the surface in the thickness direction of the second plastic encapsulation member 5. In some embodiments of the present application, the connector further includes a second connection module 16 and a second metal housing 17; the second connection module 16 is the same as or similar to the first connection module 1 and correspondingly has a second bending piece 18; the second connection module 16 and the first connection module 1 are arranged back-to-back and overlapping in the thickness direction of the connector, and the second bending piece 18 is in contact with the first bending piece 15 for electrical connection, thereby realizing the conduction of the grounding terminal 2 on the first connection module 1 and the grounding terminal 2 on the second connection module 16, thereby enhancing the shielding ability of the connector.

[0051] And, as Figure 1-6As shown, the second metal housing 17 is fixed to the second connection module 16, and is closely arranged and electrically connected with the first metal housing 14. Through such a design of internal and external connection and up-and-down connection of the internal structure, the shielding performance of the overall connector is further improved, and the ability of the connector to resist electromagnetic interference is enhanced.

[0052] As Figure 1 and Figure 5-6 shown, in some embodiments of the present application, the connector further includes a plastic housing 19. The plastic housing 19 is provided with a receiving cavity (not shown) running through its length direction. The first connection module 1 and the second connection module 16 are jointly received in the receiving cavity. The outer shape of the plastic housing is adaptively designed according to the structure and shape of the above-mentioned socket and the structure and shape of the first connection module 1 and the second connection module 16, so as to ensure that the signal terminals 3 and the ground terminals 2 located in the plastic housing 19 can be electrically connected to the corresponding contact elements in the above-mentioned socket.

[0053] As Figure 1 and Figure 5-6 shown, in some embodiments of the present application, the plastic housing 19 is provided with a fixing step 20. The first metal housing 14 and the second metal housing 17 are both provided with fixing openings 21. The fixing openings 21 are in butt joint and fixed with the fixing step 20, so as to fixedly connect the first metal housing 14 and the second metal housing 17 to the plastic housing 19 respectively; through the interference fit between the fixing step 20 and the fixing openings 21, the fitting and assembly among the plastic housing 19, the first metal housing 14 and the second metal housing 17 can be realized. The structural design of each component in the connector of the present application has the advantages of convenient and simple installation and good shielding effect.

[0054] It can be understood but it is still necessary to emphasize that, as Figure 1 shown, the longitudinal direction, width direction and thickness direction of the above-mentioned components are correspondingly designed with each other. For example, the longitudinal direction, width direction and thickness direction of the first connection module 1 and the second connection module 16 respectively correspond to the longitudinal direction, width direction and thickness direction of the overall connector in sequence; the longitudinal direction, width direction and thickness direction of the first plastic sealing member 4 and the second plastic sealing member 5 respectively located on the first connection module 1 and the second connection module 16 are also correspondingly arranged with the longitudinal direction, width direction and thickness direction of the overall connector in sequence; the longitudinal directions of the ground terminal 2 and the signal terminal 3 are adapted to the longitudinal direction of the connector; the above three directions of the remaining components not described in detail are also adapted to and correspondingly arranged with the overall connector as described above.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
