Technical Field

[0002] Line-end connectors are detachable electrical connectors fixed to the end of cables. They are used in pairs with board-end connectors fixed on PCBs or equipment panels to enable rapid connection and interchange of current and signals.

[0003] In wire connectors, multiple cables must be arranged in parallel on the same substrate to achieve multi-channel parallel transmission. However, when high-frequency signals are running, the electromagnetic fields of the cables overlap due to their close proximity, which can easily form coupling paths. This causes electromagnetic interference to propagate along the adjacent lines, disrupting the signal integrity of the cable itself and potentially radiating to surrounding circuits, leading to electromagnetic compatibility failure of the entire device.

[0023] In existing technologies, when multiple cables are arranged in parallel on a wire-end connector, the operation of high-frequency signals can easily cause electromagnetic field overlap between the cables, forming coupling paths that impair signal integrity. Traditional structures lack effective electromagnetic isolation measures, allowing electromagnetic interference from adjacent cables to easily propagate along neighboring lines and even radiate to surrounding circuits, causing overall electromagnetic compatibility failure.

[0024] To address the aforementioned problems, this utility model proposes a connector assembly 1000. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 A schematic diagram of an embodiment of the connector assembly 1000 provided by this utility model.

[0025] Please refer to Figure 1 , Figure 2 as well as Figure 3 This utility model proposes a connector assembly 1000, including a front substrate 1, a rear substrate 2, multiple shielding sheets 3, and multiple cables 4; the front substrate 1 includes a plate body 11, a grounding structure, and multiple signal terminals 13; each signal terminal 13 is disposed on the plate body 11; the grounding structure includes a grounding sheet 121 and multiple grounding terminals 122, the grounding sheet 121 is snapped into the plate body 11, and each grounding terminal 122 is disposed on the plate body 11 and electrically connected to the grounding sheet 121; the rear substrate 2 is assembled and connected to the plate body 11; each shielding sheet 3 is snapped into the rear substrate 2 and is spaced apart along the length direction of the plate body 11; the grounding sheet 121 is inserted into each shielding sheet 3, and each grounding terminal 122 is electrically connected to the corresponding shielding sheet 3; the conductor in each cable 4 is electrically connected to two signal terminals 13; each cable 4 is disposed on the rear substrate 2, and there is a shielding sheet 3 between the ends of two adjacent cables 4 near the plate body 11.

[0026] The front substrate 1 is the basic component that carries signal transmission and grounding functions. It can be implemented using an injection-molded insulating substrate. Its plate 11 has signal terminals 13 for transmitting electrical signals, and the grounding plate 121 forms a conductive path with the grounding terminal 122. The rear substrate 2 is the support structure that cooperates with the front substrate 1 for installation. It can be detachably connected using a snap-fit ​​or screw fixing method and is used to support the shielding plate 3 and the cable 4. The shielding plate 3 is a metal component used for electromagnetic isolation. It can be implemented using a stamped copper alloy sheet and is fixed to the rear substrate 2 by a snap-fit ​​method to form a stable mechanical connection. The grounding plate 121 is inserted into the shielding plate 3, indicating physical contact and conduction between the metal plates. A low-impedance electrical connection can be achieved using elastic contact or crimping. The shielding plate 3 is located near the end of the cable 4 near the plate 11, indicating electromagnetic isolation at the signal transmission start point. Near-end field suppression can be achieved by vertically inserting the shielding plate 3 into the gap of the cable 4. The conductor inside the cable 4 is conductive and used for electrical connection with the signal terminal 13.

[0027] Specifically, the front substrate 1's plate 11 serves as the mounting carrier, with signal terminals 13 arranged along its length to form a signal transmission channel. Grounding plates 121 extend along the length of the plate 11, forming a continuous grounding path with each shielding plate 3 via a plug-in connection. After assembly, the rear substrate 2, together with the plate 11, forms the cable 4 mounting space. Shielding plates 3 are vertically inserted into this space, dividing the cable 4 into independent areas. When high-frequency signals are transmitted through the cable 4, the electromagnetic fields generated by adjacent cables 4 are physically blocked by the shielding plates 3. Simultaneously, the shielding plates 3, through the conductive loop formed by the grounding terminal 122 and the grounding plate 121, guide interference signals into the grounding system. The spaced-out arrangement of the shielding plates 3 along their length ensures electromagnetic isolation while avoiding the weight increase brought by the overall shielding structure.

[0028] Compared to existing technologies, traditional solutions often employ either a monolithic metal shielding layer or increased cable spacing. The former leads to structural complexity and affects heat dissipation, while the latter sacrifices connector compactness. This solution, however, achieves directional electromagnetic shielding while maintaining connector miniaturization through a discrete shielding plate design. Existing technologies often use single-point grounding paths, easily forming grounding loops. In this solution, the insertion structure of the shielding plate 3 and the grounding plate 121 forms distributed grounding points, effectively reducing grounding impedance. Furthermore, the snap-fit ​​structure between the shielding plate 3 and the back substrate 2 facilitates maintenance and replacement compared to traditional soldering or bonding methods.

[0029] Through the above technical solutions, this application effectively suppresses electromagnetic coupling between adjacent cables and blocks the propagation path of interference signals. The discrete shielding structure forms multiple electromagnetic isolation zones within a limited space, significantly improving signal transmission integrity. The distributed grounding network reduces high-frequency grounding impedance and minimizes electromagnetic radiation leakage. The modular assembly design improves production and assembly efficiency while ensuring shielding effectiveness.

[0030] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment of the present invention, the shielding sheet 3 has a notch 3a at one end facing the plate 11, and an extension portion 31 extends from each of the two side walls of the notch 3a into the notch 3a; the grounding sheet 121 is inserted into the notch 3a and sandwiched between the two extension portions 31.

[0031] In this design, notch 3a refers to the inwardly recessed opening at the top of the shielding plate 3. This can be achieved by stamping a U-shaped or V-shaped recess at the top of the metal shielding plate 3 to accommodate the insertion of the grounding plate 121. Extension 31 refers to the sheet-like structures extending inward from both sides of notch 3a. This can be achieved by stamping to form a metal sheet that slopes inward towards the center on the sidewalls of notch 3a, used to clamp the grounding plate 121 and form a stable contact surface. Grounding plate 121 is a conductive metal component, specifically formed by stamping a thin copper alloy sheet. After being inserted into notch 3a, it contacts extension 31 to establish a conductive path between the shielding plate 3 and the grounding terminal 122.

[0032] Specifically, after a notch 3a is machined at the top of the shielding plate 3, its two side walls extend inward to form extensions 31, creating a clamping space between the two extensions 31. When the grounding plate 121 is inserted into the notch 3a, the extensions 31 use their own elastic deformation to clamp the grounding plate 121, creating multi-point contact between the grounding plate 121 and the shielding plate 3. The cooperation of multiple clamping structures can prevent the grounding plate 121 from shifting under vibration or external force, ensuring the conductive continuity between the shielding plate 3 and each grounding terminal 122, thereby reducing the probability of electromagnetic coupling between cables 4.

[0033] The grounding plate 121 is elastically clamped by the cooperation of the notch 3a and the extension 31, and the deformation generates a continuous clamping force, thereby effectively suppressing electromagnetic interference between cables 4 during high-frequency signal transmission, ensuring signal integrity, and at the same time enhancing the mechanical connection strength between the shielding plate 3 and the grounding plate 121, avoiding electromagnetic leakage problems caused by poor contact.

[0034] Please refer to Figure 4 In one embodiment of the present invention, the distance between the two extensions 31 gradually decreases along the direction from the top of the notch 3a toward the bottom of the notch 3a. The gradually decreasing spacing refers to the linear or non-linear reduction in the lateral distance between the extensions 31 from the opening of the notch 3a to the bottom. This can be achieved by setting the inner surface of the extension 31 to be an inclined plane or an arc surface. Its function is to increase the contact pressure between the grounding plate 121 and the shielding plate 3 through a progressive clamping mechanism.

[0035] Specifically, when the grounding piece 121 is inserted into the notch 3a of the shielding piece 3, the large gap at the top of the extension 31 allows the grounding piece 121 to be smoothly inserted. As the insertion depth increases, the gap between the extensions 31 gradually decreases to form a wedge-shaped clamping area, which forces the grounding piece 121 to make elastic deformation contact with the inner wall of the extension 31. This results in the force of the two extensions 31 clamping the grounding piece 121 gradually increasing, significantly improving the contact stability.

[0036] The gradually varying spacing design allows the contact pressure to be dynamically adjusted with the insertion depth, forming a self-locking crimp after assembly. This avoids contact failure caused by high-frequency vibration, improves the electrical connection stability between the grounding piece 121 and the shielding piece 3, reduces electromagnetic leakage caused by poor contact, and ensures that the shielding layers between adjacent cables 4 form a continuous equipotential body, thereby suppressing near-end crosstalk during high-frequency signal transmission.

[0037] In one embodiment of this utility model, the grounding piece 121 is a double-layered elastic piece formed by bending. When the grounding piece 121 is inserted into the notch 3a, the elasticity of the grounding piece 121 and the elasticity of the two extensions 31 are superimposed, which can further improve the electrical connection stability between the grounding piece 121 and the shielding piece 3.

[0038] Please refer to Figure 4 In one embodiment of the present invention, the shielding sheet 3 has a protrusion 32 and a contact portion 33 protruding from one end facing the plate 11; each grounding terminal 122 is inserted between the protrusion 32 and the contact portion 33 of the corresponding shielding sheet 3, and the extension portion 31 extends from the contact portion 33 into the notch 3a.

[0039] The protrusion 32 refers to the raised structure formed by the shielding sheet 3 facing the plate 11. Specifically, it can be formed as a vertical protrusion on the surface of the shielding sheet 3 by a stamping process, which is used to limit the insertion of the grounding terminal 122. The contact part 33 refers to another raised structure formed by the shielding sheet 3 facing the plate 11. Specifically, it can be formed by a stamping process symmetrical to the protrusion 32, which is used to form a surface contact with the grounding terminal 122 to achieve a conductive connection.

[0040] Specifically, the shielding plate 3 forms a clamping space through the protrusion 32 and the contact portion 33. After the grounding terminal 122 is inserted into this space, it is limited and fixed by the protruding structures on both sides to prevent loosening of the contact due to vibration or external force. The extension portion 31 extends from the contact portion 33 into the notch 3a, so that the grounding plate 121 can be clamped by the extension portion 31 when inserted into the notch 3a, and at the same time forms a parallel conductive path with the contact portion 33, thereby improving the current conduction capability between the shielding plate 3 and the grounding plate 121.

[0041] By combining the protrusion 32 and the contact 33, multi-point contact and mechanical limiting are achieved in a limited space, which not only enhances the conductivity but also improves the vibration resistance. This solves the signal crosstalk problem caused by electromagnetic interference between cables 4 in high-frequency signal transmission. By optimizing the contact structure between the shielding plate 3 and the grounding terminal 122, the contact resistance is reduced and the shielding effectiveness is improved, thereby reducing energy loss and electromagnetic radiation during signal transmission.

[0042] Please refer to Figure 4 In one embodiment of this utility model, the contact portion 33 is provided with a through hole 33a.

[0043] Among them, through hole 33a refers to a hole-like structure that penetrates the thickness of contact portion 33, which can be achieved by stamping or drilling.

[0044] Specifically, the through-hole 33a forms a multi-point contact path during the insertion of the shielding plate 3 and the grounding terminal 122. When the grounding plate 121 is inserted into the notch 3a and the grounding terminal 122 is inserted into the gap between the protrusion 32 and the contact portion 33, the metal material at the edge of the through-hole 33a undergoes elastic deformation under the insertion pressure, changing the size of the through-hole 33a. This allows the shielding plate 3 to adapt to grounding structures of different sizes and specifications. At the same time, the through-hole 33a structure further disperses the insertion stress, preventing the contact portion 33 from undergoing plastic deformation due to stress concentration.

[0045] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, a plurality of mounting grooves 2a are provided at one end of the rear substrate 2 facing the plate 11, and each shielding sheet 3 is engaged with the groove wall of the corresponding mounting groove 2a.

[0046] The mounting groove 2a refers to a recessed structure formed on the surface of the back substrate 2, which can be achieved by mechanical stamping or injection molding, and is used to accommodate the insertion and positioning of the shielding sheet 3. The snap-fit ​​refers to the fixing of components through mechanical interlocking, which can be achieved by elastic deformation or interference fit, so that the shielding sheet 3 and the groove wall of the mounting groove 2a form a tool-free connection.

[0047] Specifically, the shielding plate 3 is assembled and positioned with the rear substrate 2 by inserting it into the mounting groove 2a. The groove wall of the mounting groove 2a provides lateral constraint to the shielding plate 3, preventing it from shifting in the direction parallel to the length of the plate 11. The snap-fit ​​structure between the shielding plate 3 and the groove wall generates continuous normal pressure, keeping the shielding plate 3 fixed in the vertical direction. This assembly method establishes a stable mechanical connection between the shielding plate 3 and the rear substrate 2, ensuring reliable electrical contact between the shielding plate 3 and the grounding terminal 122, while providing continuous spatial isolation for adjacent cables 4.

[0048] The snap-fit ​​structure enables rapid installation of the shielding sheet 3. The geometric constraints of the mounting slot 2a allow for precise alignment of multiple shielding sheets 3, forming a uniformly distributed electromagnetic isolation barrier. This achieves efficient assembly and precise positioning of the shielding sheet 3, ensuring the continuity of the electromagnetic shielding structure between adjacent cables 4. The cooperation between the mounting slot 2a and the snap-fit ​​structure effectively suppresses the risk of displacement of the shielding sheet 3 in a vibration environment, improves the stability of high-frequency signal transmission, and reduces crosstalk caused by electromagnetic coupling between cables 4.

[0049] Please refer to Figure 3 and Figure 5 In one embodiment of the present invention, a slot 2a1 is provided on each of the opposite side walls of the mounting groove 2a, and a fixing part 34 protruding outward is formed on each of the opposite side walls of the corresponding shielding sheet 3, and each fixing part 34 is engaged in a slot 2a1.

[0050] The slot 2a1 refers to the symmetrically arranged recessed structures on both sides of the mounting slot 2a. Specifically, a groove with a guide slope can be formed on the side wall of the mounting slot 2a through stamping or cutting processes, which is used to form a mechanical interlock with the fixing part 34 of the shielding sheet 3. The fixing part 34 refers to the protruding structures extending outward from both sides of the shielding sheet 3. Specifically, a barbed protrusion with elastic deformation capability can be formed on both sides of the shielding sheet 3 through stamping processes, which is used to form an interference fit with the slot 2a1.

[0051] Specifically, when the shielding plate 3 is pressed into the mounting groove 2a during assembly, the fixing part 34 undergoes elastic deformation due to the pressure from the side wall of the mounting groove 2a. After the shielding plate 3 reaches the predetermined position, the geometric contour of the fixing part 34 matches the groove 2a1 and recovers its deformation, forming a stable three-point snap-fit ​​structure. The contact surface between the shielding plate 3 and the mounting groove 2a generates continuous positive pressure through the interference fit between the fixing part 34 and the groove 2a1, preventing the shielding plate 3 from axial displacement or circumferential deflection in a vibration environment.

[0052] The bidirectional constraint formed by the symmetrically distributed fixing parts 34 on both sides and the slot 2a1 establishes mechanical limits in both the thickness and length directions of the shielding sheet 3, effectively suppressing the positional displacement of the shielding sheet 3 under thermal cycling conditions. This achieves efficient and reliable assembly of the shielding sheet 3 and the back substrate 2, avoiding quality fluctuations caused by manual soldering processes and improving the production consistency of the connector assembly 1000. The double-sided fixing structure enhances the vibration resistance of the shielding sheet 3 under complex working conditions, ensures the stability of the grounding connection between the cable 4 and the shielding sheet 3, and suppresses electromagnetic leakage during high-frequency signal transmission. The snap-fit ​​assembly method simplifies the production process, allowing the shielding sheet 3 to be directly pressed into the back substrate 2 after injection molding, reducing the overall manufacturing cost of the connector assembly 1000.

[0053] Please refer to Figure 1 and Figure 6 In one embodiment of the present invention, the plate 11 has an opening 11a facing the rear substrate 2, and the opening 11a extends along the length direction of the plate 11; the grounding piece 121 is inserted into the opening 11a.

[0054] The socket 11a refers to a recessed space formed on the plate 11, with its opening facing the rear substrate 2. This recess can be achieved through machining or injection molding and is used to accommodate the insertion of the grounding piece 121. The interface provides a fixed mounting space for the grounding piece 121, ensuring its stable positioning along the length of the plate 11. The grounding piece 121 being inserted into the socket 11a means that the grounding piece 121 forms a mechanical connection with the socket 11a through insertion. This can be achieved using an interference fit or a snap-fit ​​structure. This design ensures reliable contact between the grounding piece 121 and the plate 11, preventing displacement due to vibration or external forces and ensuring grounding continuity.

[0055] Specifically, the socket 11a extends along the length of the plate 11 to form a continuous channel. After being inserted, the grounding piece 121 is distributed along the channel, forming multi-point contact with the shielding piece 3. When the plate 11 is assembled with the back substrate 2, the opening direction of the socket 11a aligns the insertion path of the grounding piece 121 with that of the shielding piece 3. The grounding piece 121 is constrained by the channel wall within the socket 11a, reducing lateral offset. The extension direction of the socket 11a is consistent with the cable 4 arrangement direction, so that the grounding piece 121 covers the entire length of the cable 4 group, forming a continuous shielding layer.

[0056] By embedding the grounding piece 121 into the plate 11 through the socket 11a structure, space is saved and the displacement of the grounding piece 121 is restricted by the slot wall of the socket 11a, which improves the vibration resistance and solves the problem of the shielding effectiveness fluctuation caused by the unstable installation of the grounding piece 121 under high frequency signals. The socket 11a structure makes the grounding piece 121 and the plate 11 form an integrated assembly, reducing contact impedance and optimizing the electromagnetic shielding uniformity, thereby suppressing electromagnetic coupling interference between cables 4.

[0057] Please refer to Figure 6 In one embodiment of the present invention, the plate body 11 includes an upper plate 111 and a lower plate 112 that are assembled together, and the upper plate 111 and the lower plate 112 surround to form an insertion port 11a.

[0058] Among them, the assembly connection refers to the upper plate 111 and the lower plate 112 being fixed to each other by a detachable mechanical structure, which can be achieved by means of buckles, screws or slide rails, which facilitates the processing and maintenance of the socket 11a.

[0059] Specifically, the upper plate 111 and the lower plate 112 are assembled to form the plate body 11, and the socket 11a is formed by the gap after the upper and lower plates 112 are mated. During the assembly process, the grounding piece 121 is pre-placed in the reserved position of the lower plate 112, and then the upper plate 111 and the lower plate 112 are aligned and fixed, so that the socket 11a extends along the length direction of the plate body 11, and the grounding piece 121 is confined within the socket 11a.

[0060] In some specific embodiments, the contact surfaces of the upper plate 111 and the lower plate 112 may be provided with guide protrusions and grooves to assist in rapid positioning; the cross-sectional shape of the socket 11a may be rectangular or trapezoidal, for example, a rectangular cross-section may be used to adapt to the flat structure of the grounding piece 121. The split structure simplifies the molding process of the socket 11a, reduces the processing difficulty, and improves assembly efficiency and structural stability. The split plate design ensures the dimensional accuracy of the socket 11a, and the grounding plate 121 and the shielding plate 3 form a continuous and tight electromagnetic shielding path, effectively blocking the coupling interference between cables 4 and improving the stability of signal transmission.

[0061] It is understood that the material of the plate 11 can be rubber or plastic. In one embodiment of this utility model, the material of the plate 11 is plastic.

[0062] The plate 11 refers to the base structure that carries the signal terminal 13 and the grounding structure. It can be made using injection molding, for example, using engineering plastics such as polycarbonate or nylon. Plastic materials have insulating properties, which can block direct current conduction. They also have the advantages of being lightweight and malleable, making it easy to process complex structures.

[0063] Specifically, the board 11, as the core component of the front substrate 1, uses plastic material to achieve electrical isolation, avoiding the parasitic capacitance effect caused by the conductivity of the metal substrate. During assembly, the plastic board 11 is formed into structures such as the socket 11a and snap-fit ​​positions through injection molding, and is mechanically fixed to the grounding plate 121 and the signal terminal 13. Since the plastic is non-conductive, the insulation distance between the grounding terminal 122 and the signal terminal 13 is ensured, thereby suppressing electromagnetic coupling caused by the conductivity of the substrate during high-frequency signal transmission.

[0064] By replacing metal with plastic material, its insulating properties are used to block electromagnetic field overlap. At the same time, the injection molding process achieves precise structural adaptation, balancing functionality and processing efficiency. This effectively reduces the risk of electromagnetic interference propagation between cables. The plastic plate 11 suppresses signal crosstalk by blocking conductive paths, while simplifying the substrate processing flow and improving the stability and electromagnetic compatibility of high-frequency signal transmission.

[0065] Please refer to Figure 3In one embodiment of the present invention, the multiple cables 4 of the connector assembly 1000 can be distributed in two rows at intervals along a direction perpendicular to the length direction of the plate 11.

[0066] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
