[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0045] With the continuous development of information transmission technology, the requirements for information transmission speed are increasing, which in turn places higher demands on the performance of connectors used for information transmission. This requires not only better materials and higher precision, but also more stringent process assurance. Therefore, using existing production methods significantly increases production difficulty, costs, and yield rates. Furthermore, due to limitations in material properties and manufacturing processes, producing high-performance connectors that fully meet technical standards remains challenging, often resulting in low yield rates and high processing costs.

[0046] Therefore, this utility model proposes a core component for a Type-C side-mounted female connector, aiming to solve any of the above-mentioned technical problems.

[0047] Please see Figure 1In one embodiment of this utility model, the core component includes a support structure 100, two terminal assemblies 200, and a cover assembly 300. The support structure 100 includes a plastic body 110 and a metal signal isolation plate 120 embedded in the plastic body 110. The two terminal assemblies 200 are respectively disposed in the mounting grooves 111 on opposite side surfaces of the plastic body 110. The cover assembly 300 includes a first cover 310 and a second cover 320, which are respectively fastened to opposite side surfaces of the plastic body 110 and press against the terminal assemblies 200. The support structure 100 includes a plug-in end 101 protruding from the cover assembly 300.

[0048] The technical solution of this utility model provides electromagnetic shielding by embedding a metal signal isolation plate 120 into the plastic body 110 within the support structure 100. The integrated design of the metal signal isolation plate 120 effectively isolates electromagnetic interference between adjacent terminals, suppresses echo crosstalk, far-end crosstalk, and near-end crosstalk, reduces signal loss, fully ensures signal integrity in high-speed transmission scenarios, and optimizes signal transmission performance. The terminal assembly 200 is placed in the assembly slot 111 at the bottom / side for pre-installation guidance, and is stably pressed against the terminal assembly 200 by the upper and second snap covers 320, preventing terminal loosening or poor contact, improving the mechanical reliability and connection stability of the connector, enhancing structural stability, simplifying the traditional multi-part assembly process, reducing assembly errors, reducing production complexity, thereby improving yield and reducing production costs.

[0049] The core component of this connector achieves both signal transmission stability and structural compactness through a modular design. Specifically:

[0050] Reference Figure 2 The supporting structure 100 provides a basic mounting frame for the components. Its main body is a plastic body 110 (which can be made of high-temperature resistant, high-insulation engineering plastics such as PBT or LCP), with a metal signal isolation plate 120 (preferably made of copper or aluminum alloy) embedded inside. The metal signal isolation plate 120 extends along the length of the plastic body 110, physically separating the signal paths of the two adjacent terminal assemblies 200, effectively suppressing crosstalk problems in high-frequency signal transmission. Assembly grooves 111 are symmetrically formed on opposite sides of the plastic body 110, with pre-set positioning ribs and snap-fit ​​structures inside the grooves for precise fixing of the terminal assemblies 200.

[0051] Combination Figures 3 to 5The terminal assembly 200 includes multiple high-frequency signal terminals 220 and multiple ground terminals 210, which are respectively embedded in the assembly groove 111. The contact portion of the terminal is exposed on the surface of the plastic body 110, forming an electrical connection with the external mating component. The lead end of the terminal extends to the rear end of the support structure 100 through a bending design, which facilitates soldering to the PCB board.

[0052] Reference Figures 1 to 3 The cover assembly 300 includes a first cover 310 and a second cover 320 (using the same insulating material as the plastic body 110). These covers engage with the two side edges of the plastic body 110 via snap-fit ​​mechanisms (assembly posts are provided in this design). After engagement, the inner side of the cover assembly 300 presses against the central area of ​​the terminal assembly 200 to prevent displacement of the terminals due to vibration or insertion / extraction forces, ensuring contact stability. Because exposed space for the terminal contacts needs to be reserved during assembly (or because the two ends of the plastic body 110 need to connect to external structures), the cover assembly 300 only covers the central area of ​​the plastic body 110, resulting in exposed insertion ends 101 at both ends of the support structure 100. These insertion ends 101 can directly mate with the interface of the adapter connector.

[0053] Specifically, the metal signal isolation plate 120 and the plastic body 110 are integrally formed by insert injection molding; the integral molding of the metal signal isolation plate 120 and the plastic body 110 by insert injection molding ensures the relative positional accuracy of the isolation plate and the terminal, effectively reducing signal crosstalk; at the same time, the rigid pressing design of the cover assembly 300 against the terminal makes the terminal contact pressure stable and avoids poor contact caused by vibration.

[0054] The modular design of the supporting structure 100 and the cover assembly 300 simplifies the traditional multi-step assembly of connectors ("base-terminal-shell") into a four-step process: "insert injection molding-terminal insertion-cover fastening-overall packaging," improving production efficiency. The exposed plug-in terminal 101 design reduces intermediate transition components, shortening the overall length to meet the needs of miniaturized electronic devices. The use of insert injection molding and overmolding integrated molding processes reduces redundant components such as metal shells, lowering material costs.

[0055] Combination Figure 2Furthermore, the plastic body 110 is provided with a plurality of placement ribs 112, which are used to separate adjacent terminal assemblies 200. The second cover 320 and / or the first cover 310 are provided with rib receiving grooves 301 corresponding to the placement ribs 112, and the placement ribs 112 are placed in the rib receiving grooves 301. A plurality of placement ribs 112 are integrally formed on the surface of the plastic body 110 (corresponding to the interval area of ​​the terminal assembly 200 mounting groove 111). The height is higher than the bottom surface of the mounting groove 111 (e.g., 0.5mm-2mm), and the spacing between adjacent ribs matches the width of the terminal assembly 200. The longitudinal extension of the vertical ribs allows their sides to fit against the edge of the terminal assembly 200, forming a "slot-like" constraint that restricts the left-right wobbling of the terminals during insertion and removal. The inner side of the first cover 310 and / or the second cover 320 (corresponding to the location of the vertical rib 112) is provided with a vertical rib receiving groove 301, the width and depth of which precisely match the dimensions of the vertical rib 112. When the cover assembly 300 is fastened to the plastic body 110, the vertical rib 112 is fully embedded in the receiving groove, forming a "mortise and tenon" connection structure. The engagement of the vertical rib receiving groove 301 and the vertical rib 112 not only provides precise guidance for the cover fastening (avoiding misalignment), but also enhances the connection strength between the cover assembly 300 and the plastic body 110 through the interference fit (in local areas) between the vertical rib and the receiving groove, preventing the cover from loosening under vibration. The placement of the vertical rib 112 reduces signal crosstalk between adjacent terminals, while the suppression of terminal wobbling reduces fluctuations in contact impedance, ensuring the stability of signal transmission.

[0056] Furthermore, the metal signal isolation plate 120 is provided with elastic abutment sections 122 distributed on both sides of the plate body, and the plastic body 110 is provided with clearance holes 113 corresponding to the elastic abutment sections 122. The elastic abutment sections 122 pass through the clearance holes 113 and abut against the terminal assembly 200. The elastic abutment sections 122 extend from both sides of the plate body of the metal signal isolation plate 120 (corresponding to the positions of the terminal assembly 200) to form elastic abutment sections 122. These sections adopt a thin plate structure and are pre-bent in the direction of the terminal assembly 200 (bending angle 5°-10°) to form elastic cantilever. A clearance hole 113 is provided at the corresponding position of the plastic body 110 (the hole diameter is slightly larger than the cross-sectional size of the elastic abutment section 122). After the elastic abutment section 122 passes through the clearance hole 113, its free end elastically abuts against the side or bottom of the terminal assembly 200. After the terminal assembly 200 is installed into the assembly slot 111, the elastic abutment section 122 provides a certain elastic pressure to ensure good contact with the terminal assembly 200, thereby enhancing the signal isolation effect. It provides continuous pressure through elastic deformation. The elastic design of the abutment section can adaptively compensate for assembly errors, ensuring stable contact pressure during long-term use. In connector insertion and removal or vibration scenarios, it prevents poor contact caused by terminal fretting wear. The elastic section contacts the grounding terminal 210, improving the shielding effectiveness.

[0057] Combination Figure 2 Furthermore, the metal signal isolation plate 120 also has a central glue passage hole 123 in the central area of ​​its body. One to three central glue passage holes 123 (circular, oblong, rectangular, or T-shaped, etc.) are formed in the central area of ​​the metal signal isolation plate 120 (excluding critical signal isolation paths). These glue passage holes are typically used during injection molding to allow plastic material to flow through, making the metal insert more firmly bonded to the plastic body 110. During injection molding, the central glue passage holes 123 allow plastic to fill the holes, forming a mechanical lock, preventing the metal plate from separating from the plastic body 110, and enhancing structural strength.

[0058] Combination Figure 2 Furthermore, the metal signal isolation plate 120 is provided with edge glue passage holes 124 on both sides of its body. Multiple edge glue passage holes 124 (square or oblong) are provided on both sides of the metal signal isolation plate 120 (spaced apart along its length). Similarly, the edge glue passage holes 124 are also for the flow of plastic material during injection molding, which can further strengthen the bond between the metal plate and the plastic body 110, especially at the edges, preventing cracking or separation. The glue passage holes on both sides complement the center, ensuring a more uniform bond between the entire metal plate and the plastic.

[0059] Combination Figure 4 and Figure 5 Furthermore, the terminal assembly 200 includes multiple high-frequency signal terminals 220 and multiple grounding terminals 210. The multiple grounding terminals 210 are arranged at intervals, and the multiple high-frequency signal terminals 220 are respectively disposed between two adjacent grounding terminals 210. Each high-frequency signal terminal 220 includes a contact section 221 and a variable-diameter section 222 extending from the contact section 221 towards the root of the terminal. The cross-sectional area of ​​the variable-diameter section 222 is smaller than that of the contact section 221, and the length of the variable-diameter section 222 is L, 0.45mm≤L≤0.55mm. By placing the high-frequency signal terminals 220 between the grounding terminals 210, a structure similar to a "grounding shield" is formed, reducing crosstalk between adjacent high-frequency signals. The reduced cross-sectional area of ​​the variable-diameter section 222 is used to adjust the characteristic impedance to match the transmission line, reducing signal reflection and improving signal integrity. The limitation of the length L enables optimal impedance transformation at a specific frequency, avoiding signal reflection and distortion, making it suitable for high-speed data transmission scenarios.

[0060] Reference Figure 5The variable diameter section 222 is a rectangular or circular necked structure; of course, it can also be any other structure in which the cross-sectional area of ​​the variable diameter section 222 is smaller than the cross-sectional area of ​​the contact section 221. In this embodiment, the length L of the variable diameter section 222 is limited to 0.45mm≤L≤0.55mm (preferably 0.5mm), and the cross-sectional size is adjusted according to the target impedance requirement. By designing an impedance transformation section with a smaller cross-section, the characteristic impedance of the terminal can be locally improved, and the high-speed signal transmission performance can be optimized.

[0061] Reference Figure 3 and Figure 4 Furthermore, the plastic body 110 has a recessed step 114 at the end of the plug-in end 101 of the terminal assembly 200, and the end of the grounding terminal 210 has a pre-embedded step surface 211 corresponding to the recessed step 114, the pre-embedded step surface 211 fitting the recessed step 114; at the end of the plug-in end 101 of the plastic body 110 (i.e., the front end area where the connector contacts the external mating part), a recessed step 114 is formed along the arrangement direction of the terminal assembly 200 (step depth 0.1-0.3mm, width matching the end of the grounding terminal 210). Correspondingly, the end of the grounding terminal 210 (plug-in end 101) is integrally formed with a pre-embedded step surface 211, the height of which is consistent with the depth of the recessed step 114, and the contour of the step surface completely fits the shape of the recessed step 114 (gap fit tolerance ≤ 0.02mm). During assembly, the pre-embedded stepped surface 211 of the grounding terminal 210 is embedded in the recessed step 114 of the plastic body 110, forming a precise "step-step surface" fitting structure. The recessed step 114 is only set in the area of ​​the plastic body 110 corresponding to the grounding terminal 210, and the plug end 101 of the high-frequency signal terminal 220 retains its original planar structure, ensuring that the contact between the signal terminal and the mating part is not affected.

[0062] In traditional designs, the insertion end 101 of the grounding terminal 210 is prone to slight tilting due to the impact of insertion and extraction forces, resulting in poor grounding path contact and reduced shielding effect. By mechanically engaging the recessed step 114 with the pre-embedded step surface 211, the grounding terminal 210 and the grounding spring of the mating part are ensured to make precise contact.

[0063] Combination Figure 2Furthermore, the plastic body 110 is also provided with high-frequency performance holes 115, which are located below the terminal assembly 200. Multiple high-frequency performance holes 115 are formed below the corresponding area of ​​the terminal assembly 200 on the plastic body 110 (i.e., the bottom area where the terminal contacts the plastic body 110). The arrangement of the holes is as follows: at least one hole (penetrating the plastic body 110) corresponds to each outermost high-frequency signal terminal 220. The axis of the hole coincides with or is parallel to the central axis of the terminal, and the hole contains air (without filling other materials). After forming the high-frequency performance holes 115, the medium below the terminal changes from plastic to a composite medium of "air + plastic," which reduces parasitic capacitance and avoids signal reflection caused by impedance abrupt changes. By reducing the contact impedance fluctuation of the grounding terminal 210 and optimizing the impedance continuity of the signal terminals, noise, jitter, and attenuation in signal transmission are reduced, meeting the requirements for higher data transmission rates. Moreover, the opening of the high-frequency performance hole 115 reduces the amount of material used in the plastic body 110 and eliminates the need for additional metal parts, achieving a lightweight design while improving performance, which is in line with the miniaturization trend of consumer electronic devices.

[0064] Combination Figure 2 Furthermore, the first cover 310 has a first mounting hole 311 and a first pressing surface 312; a first mounting post 116 is provided on the corresponding surface of the plastic body 110, the first mounting post 116 is engaged with the first mounting hole 311, and the first pressing surface 312 abuts against the terminal assembly 200; the edge or corner area of ​​the first cover 310 is provided with a first mounting hole 311 (circular or square through hole, the inner wall may be provided with barbs or snap-fit ​​structure), and the corresponding surface (top) of the plastic body 110 is integrally formed with a first mounting post 116 (the diameter is interference fit with the mounting hole). During assembly, the first mounting post 116 is inserted into the first mounting hole 311 and fastened by snap-fit ​​or interference fit. At the same time, the inner side of the first cover 310 (corresponding to the upper surface of the terminal assembly 200) is provided with a first pressing surface 312 (flat or slightly arcuate surface), the pressing surface is in contact with the upper surface of the contact part or welding part of the terminal assembly 200, and a preset pressure is applied. The number of first assembly holes 311 and assembly posts is usually 2-4 sets (symmetrically distributed) to ensure the parallelism between the first cover 310 and the plastic body 110.

[0065] Combination Figure 2Furthermore, the second cover 320 has a second mounting hole 321 and a second pressing surface 322; the surface of the plastic body 110 is provided with a second mounting post 117, which engages with the second mounting hole 321, and the second pressing surface 322 abuts against the terminal assembly 200; the second cover 320 is provided with a second mounting hole 321 at a corresponding position, and the lower surface of the plastic body 110 is provided with a second mounting post 117, and the assembly method is the same as that of the first cover 310 (interference fit or snap connection).

[0066] Furthermore, the first cover 310 and / or the second cover 320 are also provided with a functional adjustment groove 302 for regulating the electromagnetic field. The functional adjustment groove 302 is formed on the surface (typically a non-assembly area) of the first cover 310 and / or the second cover 320. The shape of the groove can be strip-shaped, circular, grid-shaped, or irregular polygonal, and the specific size is adjusted according to the target. For example, the strip-shaped groove can be parallel to the signal transmission direction to suppress electromagnetic radiation of a specific frequency.

[0067] Reference Figures 6 to 9 This utility model also proposes a Type-C side-mounted female connector, which includes a core component, a plastic package 400, and a metal reinforcement 500. The specific structure of the core component is as described in the above embodiments. Since this Type-C side-mounted female connector adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The plastic encapsulation body 400 covers the cover assembly 300, and the metal reinforcement 500 is sleeved on the plastic encapsulation body 400 from the plug-in end 101. The metal signal isolation plate 120 is provided with a first abutting section 121a, and the terminal assembly 200 is provided with a first contact section 201a. The plastic body 110 and the plastic encapsulation body 400 are provided with a first clearance opening 118a corresponding to the first abutting section 121a and the first contact section 201a. The first abutting section 121a and the first contact section 201a abut against the inner wall of the metal reinforcement 500.

[0068] The core component, as the signal transmission core of the connector, is responsible for physical contact with the external Type-C plug and high-speed signal transmission. The plastic encapsulation 400 forms the main insulating shell of the connector; it insulates the metal parts of the core component (terminals, isolation plates, and covers) from the external environment; and it provides a mounting base for the metal reinforcement 500, protects the core component from external impacts, and meets the space constraints of side-mounted installation.

[0069] Reference Figure 6 and Figure 7The metal reinforcement 500 is sleeved onto the plastic package 400 from the plug end 101 (i.e. the plug insertion direction), and is fixed to the package by interference fit or snap-fit ​​structure (covering 30%-50% of the front end of the package). The metal reinforcement 500 wraps around the front end of the plastic package 400 by sleeve, to prevent the plastic package 400 from cracking due to stress alone.

[0070] The first contact section 121a of the metal signal isolation plate 120 abuts against the metal reinforcement 500, which improves electromagnetic shielding. That is, the metal reinforcement 500 not only improves mechanical reliability, but its contact design with the isolation plate and terminal also strengthens electromagnetic shielding.

[0071] Reference Figure 8 and Figure 9 Furthermore, the Type-C side-mounted female connector also includes a metal shielding inner shell 600, which houses the core assembly. The metal signal isolation plate 120 has a second abutment section 121b, and the terminal assembly 200 has a second contact section 201b. The plastic body 110 and the plastic encapsulation body 400 have a second clearance opening 118b corresponding to the second abutment section 121b and the first contact section 201a. The second abutment section 121b and the second contact section 201b abut against the metal shielding inner shell 600. The core component is fully enclosed by the metal shielding inner shell 600 (covering the entire area from the plug-in end 101 to the solder end), forming a double protection with the metal reinforcement 500. The second contact section 121b of the metal signal isolation plate 120 and the second contact section 201b of the terminal assembly 200 abut against the metal shielding inner shell 600, constructing a dual-path grounding of "reinforcement grounding + shielding shell grounding", ensuring that the high-frequency signal grounding impedance always remains at a low level and avoiding the degradation of shielding performance caused by single-point failure.

[0072] Furthermore, the metal signal isolation plate 120 has a contact rib 125 on the side away from the plug-in end 101 of the terminal assembly 200. The contact rib 125 is bent relative to the metal signal isolation plate 120 and abuts against the metal shielding inner shell 600. On the non-plug-in end 101 side of the metal signal isolation plate 120 (the shielding member located between adjacent terminal assemblies 200) (i.e., the rear end region away from the plug insertion direction), a contact rib 125 is integrally formed. This rib is bent in a direction perpendicular to the plane of the isolation plate and elastically abuts against the inner wall of the metal shielding inner shell 600.

[0073] The contact rib 125 is wing-shaped, and the cross-section is "L"-shaped or "arc".

[0074] Combination Figure 2 and Figure 3Furthermore, the terminal assembly 200 also includes an abutting rib 202, which abuts against the metal shielding inner shell 600. The contact rib 125 / abutting rib 202 are integrally formed with the isolation plate / terminal through a stamping process, without the need for additional assembly parts. In addition, the first cover 310 and the second cover 320 are also provided with rib clearance grooves 303, the shape of which is adapted to the abutting rib 202. The abutting rib 202 passes through the rib clearance groove 303 and extends out of the plastic encapsulation body 400, abutting against the inner wall of the metal shielding inner shell 600 after assembly.

[0075] Reference Figure 9 Specifically, the type-c side-mounted female connector also includes a metal shielding outer shell 700 that covers the metal shielding inner shell 600.

[0076] Furthermore, the support structure 100 is encapsulated by the plastic encapsulation body 400 to achieve overall curing of the internal structure, reduce subsequent assembly steps, enhance the impact resistance and environmental interference resistance of the core components, and extend the service life of the connector.

[0077] Specifically, the plastic encapsulation body 400, the supporting structure 100, the terminal assembly 200, the first cover 310, and the second cover 320 are integrally injection molded with a plastic overmolding process. The plastic encapsulation body 400, through this integral injection molding process, completely covers the pin ends of the cover assembly 300 and the terminal assembly 200, as well as the non-plug-in areas of the supporting structure 100. High-strength epoxy resin or nylon is selected as the encapsulation material to form a sealed shell, which improves the component's impact resistance, dust and water resistance, and further secures the internal components, preventing structural loosening after long-term use.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
