[0039] This application relates to a wire-end connector assembly with a hybrid welding mechanism and its connector. For ease of explanation of the assembly features and relative positional relationships, the spatial configuration of the assembly is defined in the following description based on three mutually orthogonal axes: the horizontal axis (X-axis), the vertical axis (Y-axis), and the vertical axis (Z-axis). Specifically, the horizontal axis (X-axis) refers to the left-right extension direction. Figure 1A The lower left corner is used as the left side of the component. Figure 1AThe upper right of the axis is defined as the right side of the component; the vertical axis (Y-axis) refers to the front-to-back extension direction, where... Figure 1A The upper left corner serves as the front direction of the component. Figure 1A The lower right side is considered the rear direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 1A The area above is considered the top (top) side of the component. Figure 1A The area below is used as the bottom (bottom) side direction of the component.

[0040] In a first embodiment, please refer to Figures 1A to 1D As shown, the wire-end connector assembly S includes a connector C, multiple first transmission lines L1, and multiple second transmission lines L2, but is not limited thereto. Depending on actual needs, the wire-end connector assembly S may also only have the first transmission lines L1. Furthermore, the first transmission line L1 is in the form of a coaxial cable, which includes at least a first core wire L11, a first inner insulation layer L12, a first metal grounding layer L13, and a first outer insulation layer L14. The first core wire L11 is used to transmit electrical signals; the first inner insulation layer L12 covers the outside of the first core wire L11; the first metal grounding layer L13 is disposed outside the first inner insulation layer L12 to provide grounding and shielding functions; and the first outer insulation layer L14 covers the outside of the first metal grounding layer L13. Similarly, the second transmission line L2 is in the form of a coaxial cable, which includes at least a second core wire L21, a second inner insulation layer L22, a second metal grounding layer L23 and a second outer insulation layer L24. The second core wire L21 is used to transmit electrical signals; the second inner insulation layer L22 covers the outside of the second core wire L21; the second metal grounding layer L23 is disposed outside the second inner insulation layer L22 to provide grounding and shielding functions; and the second outer insulation layer L24 covers the outside of the second metal grounding layer L23.

[0041] Please see Figures 1A to 2BAs shown, in this first embodiment, the connector C includes a first terminal group 1, a second terminal group 2, an insulating body 3, a first intermediate grounding member 4, and a second intermediate grounding member 5, but is not limited thereto. The number, arrangement, and presence of the aforementioned components can be adjusted according to the actual needs of the product. For example, in some first embodiments, the connector C may only have the first terminal group 1 and the first intermediate grounding member 4, thereby improving the flexibility of product design. Furthermore, the insulating body 3 can be assembled from a single component or multiple components, wherein the insulating body 3 has a mating portion 31, which is plate-shaped and extends along the vertical axis (Z-axis). In this first embodiment, the mating portion 31 is composed of multiple components, but is not limited thereto. In other embodiments of this application, the mating portion 31 can be a single component and can be manufactured using an injection molding process; or, the mating portion 31 can also be integrally formed on the insulating body 3. It should be noted that the top area is omitted in the drawings of this application to show the configuration relationship of the various components inside the insulating body 3, so as to expose the internal components. In the actual product, the top of the insulating body 3 can be closed to completely cover the internal components and achieve a good protective effect.

[0042] Please refer to the following: Figures 1A to 2B As shown, the front side of the docking part 31 is provided with the first terminal group 1, and the rear side of the docking part 31 is provided with the second terminal group 2. The first terminal group 1 includes multiple first signal terminals 11 and multiple first ground terminals 12, and the multiple first signal terminals 11 and first ground terminals 12 are arranged along the horizontal axis (X-axis). The second terminal group 2 includes multiple second signal terminals 21 and multiple second ground terminals 22, and the multiple second signal terminals 21 and second ground terminals 22 are arranged along the horizontal axis (X-axis). In this first embodiment, the top side of the first intermediate grounding member 4 forms multiple first crests 41 and multiple first troughs 42 alternately along the horizontal axis (X-axis). The space above the first trough 42 can accommodate the first transmission line L1, and the first trough 42 can directly contact the first metal ground layer L13 to form an electrical connection. However, the first core wire L11 does not contact the first intermediate grounding member 4, but is located in the space above the first trough 42 (e.g., ...). Figures 4A to 4B(As shown). Furthermore, the first intermediate grounding member 4 can indirectly contact the first grounding terminal 12, so that the first transmission line L1 and the first grounding terminal 12 form a grounding path. Specifically, the mating portion 31 is provided with a metal partition 32 and a first metal conductive portion 33. The metal partition 32 can directly contact the bottom side of the first intermediate grounding member 4. The first metal conductive portion 33 is provided with a plurality of first protrusions 331 and a plurality of first recesses 332 interlaced along the horizontal axis (X-axis). The first protrusions 331 protrude towards the first grounding terminal 12 and can directly contact the first grounding terminal 12; the first recesses 332 are recessed towards the metal partition 32 and can directly contact the metal partition 32.

[0043] Please refer to the above. Figures 1A to 2B As shown, in this first embodiment, to enhance the overall grounding and shielding effect of connector C, a second metal conductive part 34 can also be provided. The second metal conductive part 34 is provided with a plurality of second protrusions 341 and a plurality of second recesses 342 interlaced along the horizontal axis (X-axis). The second protrusions 341 protrude toward the second grounding terminal 22 and can directly contact the second grounding terminal 22; the second recesses 342 are recessed toward the metal partition 32 and can directly contact the metal partition 32. Furthermore, in this first embodiment, the metal partition 32 is composed of multiple plates 32A and 32B, but this is not a limitation. In other embodiments of this application, the metal partition 32 can be a single component or composed of three or more components; or, the first intermediate grounding member 4 can be integrally formed with the metal partition 32; or, the first intermediate grounding member 4, the metal partition 32, and the first metal conductive part 33 can be integrally formed, so that the first intermediate grounding member 4 directly contacts the first grounding terminal 12; or, the metal partition 32 and the second metal conductive part 34 can be integrally formed; or, the second metal conductive part 34 can be omitted, etc.

[0044] In this first embodiment, please refer again Figures 1A to 4BAs shown, the second intermediate grounding member 5 differs from the first intermediate grounding member 4 in that it is a sheet, bent to form multiple second crests 51 and multiple second troughs 52 along the horizontal axis (X-axis). The space above each second trough 52 can accommodate the second transmission line L2, and the second trough 52 can directly contact the second metal grounding layer L23 to form an electrical connection. However, the second core wire L21 does not contact the second intermediate grounding member 5, but is located in the space above the second trough 52. Furthermore, the second intermediate grounding member 5 can directly contact the second grounding terminal 22, so that the second transmission line L2 and the second grounding terminal 22 form a grounding path. Specifically, the second trough 52 has an extension section 521 that extends away from the mating portion 31 and can be soldered to the second metal grounding layer L23; the second crests 51 allow the second grounding terminal 22 to be attached to and soldered to its top surface.

[0045] However, please refer to the following: Figures 1A to 4B As shown, in other embodiments of this application, the first intermediate grounding member 4 and the second intermediate grounding member 5 may have subsequent variations to meet the actual needs of the product. For example, the extension section 521 of the second trough portion 52 may be omitted; or, the structures of the first intermediate grounding member 4 and the second intermediate grounding member 5 may be interchangeable; or, the first intermediate grounding member 4 and the second intermediate grounding member 5 may adopt the same structure; or, the installation positions of the first intermediate grounding member 4 and the first transmission line L1 may be reversed. For example, Figures 3A to 3B The first intermediate grounding element 4 is located below the first transmission line L1. In other embodiments, the first intermediate grounding element 4 can be changed to be located above the first transmission line L1. In this case, the connection relationship between the two will change so that the space below the first crest 41 is used to accommodate the first transmission line L1, and the first crest 41 can directly contact the first metal grounding layer L13 to form an electrical connection. The first trough 42 can directly contact the first grounding terminal 12, or indirectly contact the first grounding terminal 12 through the metal partition 32 and / or the first metal conductive part 33. Alternatively, the installation positions of the second intermediate grounding element 5 and the second transmission line L2 can also be reversed, that is, the installation positions of the second intermediate grounding element 5 and the second transmission line L2 can be reversed. Figures 3A to 3B The position of the second intermediate grounding member 5 is adjusted to be above the second transmission line L2, so that the space below the second crest portion 51 can accommodate the second transmission line L2, and the second crest portion 51 can directly contact the second metal grounding layer L23, while the second trough portion 52 can directly or indirectly contact the second grounding terminal 22.

[0046] Therefore, please refer to the following: Figures 1A to 4BAs shown, the structure of the first / second grounding elements 4 and 5 enables grounding paths with the first / second transmission lines L1 and L2 to be established at the same horizontal position (e.g., the X-axis). Simultaneously, since the first / second core wires L11 and L21 are located within the surrounding area of ​​the first / second grounding elements 4 and 5, a good shielding effect is achieved, reducing crosstalk interference between adjacent first core wires L11 or adjacent second core wires L21, further improving signal integrity and effectively maintaining signal transmission stability. Furthermore, the wavy structure of the first / second grounding elements 4 and 5 provides multi-point contact, resulting in lower impedance grounding paths and improved anti-interference capability for high-frequency signals, ensuring signal transmission quality.

[0047] In addition, to further enhance the connection stability of the first transmission line L1, please refer to [further details needed]. Figures 1A to 4B As shown, in this first embodiment, the connector C further includes a first positioning member 6, which is located in the insulating body 3 and forms a plurality of first positioning crests 61 and a plurality of first positioning troughs 62 interlaced along the horizontal axis. Each first positioning crest 61 corresponds to one or more first troughs 42, and the space below it can accommodate the first transmission line L1 and directly contact the first metal grounding layer L13. Each first positioning trough 62 corresponds to the first crest 41 and directly contacts it, so that the first transmission line L1 is positioned between the first intermediate grounding member 4 and the first positioning member 6, allowing the first transmission line L1 to be stably maintained in its current position. However, in other embodiments of this application, the positions of the first positioning member 6 and the first intermediate grounding member 4 can be interchanged, so that the first transmission line L1 is located in the space above the first positioning troughs 62, and the first positioning crests 61 can directly contact the first troughs 42. Simultaneously, the first positioning member 6 can contact the metal partition 32. In other words, it can be regarded as... Figure 3A The first positioning element 6 and the first intermediate grounding element 4 are interchanged. In addition, the connector C may also include a second positioning element (not shown in the figure), the configuration of which may be the same as or similar to that of the first positioning element 6. Its second positioning crest corresponds to the second trough 52, and its second positioning trough corresponds to the second crest 51. It may also have another extension to contact the second metal grounding layer L23, so that the second transmission line L2 is located between the second intermediate grounding element 5 and the second positioning element, and forms an electrical connection.

[0048] Furthermore, please refer to [the relevant documents / references]. Figures 1A to 5As shown, in order to reduce the overall size of connector C and improve signal transmission stability, soldering stability, and automated soldering requirements, in this first embodiment, the first signal terminal 11 is provided with a first through hole 110. The first through hole 110 allows the first core wire L11 to extend into it, and then soldering operations can be performed around the first through hole 110 (i.e., through-hole soldering mechanism) to fix the first core wire L11 to the first signal terminal 11. See also... Figure 6 As shown, the second signal terminal 21 may be provided with a soldering area 211, which is a complete surface without perforations and can be used to attach the second core wire L21. Then, a soldering operation (i.e., a planar soldering mechanism) can be performed in the soldering area 211 to fix the second core wire L21 to the second signal terminal 21.

[0049] Please refer to the above. Figures 1A to 5 As shown, the top horizontal height of the first signal terminal 11 is higher than the top horizontal height of the second signal terminal 21 (e.g., Figure 4B As shown), the first through hole 110 is at a higher level than the top of the second signal terminal 21. Thus, due to the design of the first through hole 110, the first signal terminal 11 does not need to bend and extend to form a corresponding soldering area. Therefore, the internal components of the connector C can be compactly arranged, helping to reduce the length of the connector C in the front-to-back direction. Furthermore, the connector C has two soldering mechanisms, which improves manufacturing flexibility and allows for the selection of a suitable soldering technique based on the wire structure of the first transmission line L1 and the second transmission line L2, or the transmission requirements of the first terminal group 1 and the second terminal group 2. However, in other embodiments of this application, depending on the actual needs of the product, the structures of the first signal terminal 11 and the second signal terminal 21 can be interchanged, or they can adopt the same structural design (e.g., both the first signal terminal 11 and the second signal terminal 21 use a through hole soldering mechanism, or both use a planar soldering mechanism, etc.).

[0050] Please refer to the above. Figures 1A to 4BAs shown, to maintain the connection stability between the first signal terminal 11 and the first transmission line L1, in this first embodiment, the connector C further includes a first terminal block 7 for connecting to the first terminal group 1. For example, the first terminal block 7 can be fixed to the first signal terminal 11 and the first ground terminal 12 using an injection molding process, but is not limited thereto. The first terminal block 7 has a plurality of recesses 70, which mainly correspond to at least one first signal terminal 11, and has at least one second through hole 72. The second through hole 72 corresponds to the first through hole 110 of the first signal terminal 11, so that the first core wire L11 can pass through the first through hole 110 and the second through hole 72 before being soldered to the first signal terminal 11. Furthermore, the connector C also includes a second terminal block 8 for connecting to the second terminal group 2. Since the second signal terminal 21 uses a planar welding mechanism, the second terminal block 8 does not need to have a corresponding groove and through hole. However, when the second signal terminal 21 uses a through hole welding mechanism, the second terminal block 8 can have the same or similar structure as the first terminal block 7. In addition, the first terminal block 7 and / or the second terminal block 8 can be assembled into the insulating body 3 as independent components, or the first terminal block 7 and / or the second terminal block 8 can be integrally formed on the insulating body 3. The aforementioned "integral forming" includes the first terminal block 7 and / or the second terminal block 8 being integrally formed on some components constituting the insulating body 3 (such as: the mating part 31, etc.).

[0051] In the first embodiment described above, please refer again. Figures 1A to 4B As shown, the second core wire L21 is directly soldered to the second signal terminal 21, and the second intermediate grounding component 5 is in direct contact with the second grounding terminal 22. However, in order to improve the signal integrity and connection reliability between the second terminal group 2 and the second transmission line L2, in the second embodiment, a circuit board P can be provided in the insulating body 3. Specifically, please refer to... Figures 7A to 7D As shown, the circuit board P can be provided between the second terminal group 2 and the second transmission line L2 to optimize the matching and stability of signal transmission. It should be specifically noted that, except for the technical features specifically described later, the structure, configuration, and function of the other components in this second embodiment can refer to the aforementioned first embodiment. Therefore, for the sake of simplicity, only the following description is provided. Figures 7A to 7D The symbols represent some components of connector C and some of the first / second transmission lines L1 and L2, and the same labels will be used for the same or corresponding components.

[0052] Please refer to the following: Figures 7A to 7DAs shown, the front side of the circuit board P is provided with a plurality of first signal parts P11 and a plurality of first ground parts P12, wherein each first signal part P11 is soldered to each corresponding second signal terminal 21 to form an electrical connection with each other; each first ground part P12 is soldered to each corresponding second ground terminal 22 to form an electrical connection with each other; the rear side of the circuit board P is provided with a plurality of second signal parts P21 and a plurality of second ground parts P22, wherein each second signal part P21 is soldered to each corresponding second core wire L21 to form an electrical connection with each other; each second ground part P22 can be directly connected to the second intermediate grounding member 5', and then indirectly connected to each second metal ground layer L23 to form an electrical connection with each other. Furthermore, each of the first signal units P11 is electrically connected to each of the second signal units P21, and each of the first ground units P12 is electrically connected to each of the second ground units P22. The conductive connection between the aforementioned first / second signal units P11 and P21, and the first / second ground units P12 and P22 can be achieved through a wiring structure provided on the surface or inner layer of the circuit board P (not shown in the figure) to ensure stable signal transmission and grounding effect.

[0053] Continuing from the above, in this second embodiment, please refer again to... Figures 7A to 7D As shown, the main part of the second intermediate grounding member 5' is flat and can directly contact the second metal grounding layer L23 of each second transmission line L2. It also extends outwards with multiple overlapping tabs 523', each of which can be directly connected to the corresponding second grounding portion P22 of the circuit board P. Furthermore, since the second intermediate grounding member 5' in the second embodiment only has upward bulges on the left and right sides, the aforementioned upward bulges can be considered as the second peak portion 51', and the remaining flat portion as the second trough portion 52'. Thus, by setting up this circuit board P, a standardized wiring architecture can be designed, ensuring the consistency and reliability of signal transmission. In addition, additional circuit components, such as resistors, capacitors, filters, and / or grounding lines, can be installed on the circuit board P to optimize impedance matching, improve signal integrity, and effectively suppress electromagnetic interference (EMI). Simultaneously, the circuit board P can also serve as a mechanical support structure to enhance the overall stability and durability of the connector, reducing solder joint brittleness or poor contact caused by stress.

[0054] In addition, to improve the shielding and grounding effect, please refer to the following in this second embodiment. Figures 7A to 8CAs shown, the insulating body 3 also includes a metal shield 9', which is located in front of the first terminal group 1 and forms multiple first shielding crests 91' and multiple first shielding troughs 92' in a staggered manner along the horizontal axis. The first shielding crests 91' correspond to the first signal terminal 11 but do not contact it; the first shielding troughs 92' directly contact the corresponding first grounding terminal 12. In this second embodiment, the first shielding crest 91' has at least one abutment piece 911', which directly contacts the first positioning member 6 (e.g., abuts against the edge of the first positioning crest 61), but is not limited thereto. In other embodiments of this application, the first shielding crest 91' may not have an abutment piece 911'; or, some of the first shielding troughs 92' may directly contact the first grounding terminal 12, while others may not.
