They feature high-speed transmission, strong anti-interference capabilities, and high reliability, and are widely used in fields such as AI, servers, communication equipment, automotive electronics, and aerospace.
[0003] Existing high-speed connectors typically use PCB (Printed Circuit Board) structures for wiring to transmit signals from the wire end to the mating end. However, the close proximity of high-speed signal pins on the PCB can easily cause crosstalk, affecting signal transmission performance. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a cable connector in which the shielding sheet and terminal are integrally formed, which can reduce crosstalk and effectively improve signal transmission quality.
[0005] This invention is achieved through the following technical solution:

[0010] The terminal block body and the shielding sheet assembly are integrally injection molded to form a first plastic layer. The terminal block body and the shielding sheet assembly are embedded in the interior of the first plastic layer, and the shielding sheet assembly is at a predetermined distance from the bottom surface of the first plastic layer, so that the shielding sheet assembly in a pair of stacked terminal blocks is spaced apart from each other.
[0011] Furthermore, each terminal in the terminal block body is arranged on the first plastic layer along the width direction of the first plastic layer.
[0012] Multiple terminals are arranged at intervals along the length of the first plastic layer to form the terminal block body.
[0013] Furthermore, the upper portion inside the first plastic layer has a plurality of first mounting portions formed therein.
[0014] The first mounting portion is provided along the width direction of the first plastic layer.
[0015] The terminal is placed inside the first mounting section.
[0016] Furthermore, on the sidewall of the first plastic layer along its length, an embedding groove is provided corresponding to each of the first mounting portions, extending through the sidewall along its thickness direction. The embedding groove is used to embed the grounding terminal of the terminal.
[0017] Furthermore, a plurality of second mounting portions are formed in the lower portion inside the first plastic layer.
[0018] The shielding sheet is placed inside the second mounting section.
[0019] Furthermore, the shielding sheet includes a shielding sheet body and a plurality of pins extending out of the surface of the shielding sheet body.
[0020] The shielding plate body is disposed inside the second mounting portion, and one end of the pin extends through the second mounting portion into the interior of the first mounting portion.
[0021] Wherein, at least one pair of said pins at the same straight position along the width direction of the first plastic layer are connected to the bottom of the signal end of a single said terminal.
[0022] Furthermore, a first limiting structure is formed on the bottom side of the first plastic layer corresponding to the embedding groove.
[0023] The first limiting structure includes a dovetail groove group and a tenon group arranged sequentially along the length of the bottom of the first plastic layer. A pair of terminal blocks are connected by the dovetail groove group at the bottom of the first plastic layer and the tenon group.
[0024] Furthermore, a second limiting structure is formed on the side of the bottom of the first plastic layer away from the first limiting structure.
[0025] The second limiting structure includes a set of countersunk holes and a set of guide posts arranged sequentially along the length of the bottom of the first plastic layer. A pair of terminal blocks are connected to the guide posts by means of the set of countersunk holes at the bottom of the first plastic layer.
[0026] Further, the housing includes:
[0027] The front shell has the receiving cavity formed inside it. One end of the terminal assembly is inserted into the receiving cavity and is integrally injection molded with the front shell.

[0028] The rear housing is snapped onto the lower part of the front housing near the cable, and the rear housing supports the second plastic layer exposed at the bottom of one end of the receiving cavity.
[0029] Furthermore, a mounting groove is formed on the outer top surface of the front shell, and a snap-fit assembly is connected in the mounting groove.
[0030] Compared with the prior art, the advantages of this invention are:
[0031] 1. The cable connector of the present invention, which integrates the shielding sheet and the terminal, includes a housing, a terminal assembly, and a cable. Each pair of terminal blocks in the terminal assembly is integrally injection molded using a terminal block body and a shielding sheet assembly welded to the bottom of the terminal block body. The sides of corresponding shielding sheet assemblies in the pair of terminal blocks are adjacent to each other. The shielding sheet assembly is welded to the bottom of the grounding terminal, and is positioned inside the first plastic layer without protruding from the bottom surface of the first plastic layer (i.e., at a predetermined distance from the bottom surface of the first plastic layer). This ensures that when the pair of terminal blocks are stacked, the shielding sheet assemblies on corresponding surfaces do not contact each other and maintain a certain distance, thereby guaranteeing signal shielding between the signal terminals on the pair of terminal blocks. Thus, by correspondingly setting shielding sheet assemblies between the bodies of a pair of terminal blocks, electromagnetic interference between signal terminals is prevented, crosstalk is reduced, and signal transmission quality is guaranteed. Compared to conventional connectors that shield external electrical signals by creating an annular space, the shielding sheet assembly in this application is used for grounding, thereby shielding against static electricity and achieving a stable signal shielding effect.
[0032] 2. The cable connector of the present invention adopts a wiring method in which the terminal and the shield are integrally injection molded. Compared with the traditional PCB wiring method, it can optimize the signal path, reduce signal attenuation and distortion, ensure the stability and integrity of signal transmission, and support longer signal path transmission.
[0033] 3. The cable connector of the present invention does not require the use of a retimer and expensive low-loss PCB materials. At the same time, the injection molding process is highly efficient and wastes less material during mass production, which can effectively reduce the overall cost. Attached Figure Description

[0049] The following detailed, non-limiting description of the invention's technical solutions, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0050] This invention provides a cable connector in which the shielding sheet and the terminal are integrally formed, such as... Figure 1 As shown, it may include a male connector 100 and a female connector 200, and the male connector 100 and the female connector 200 can be plugged into each other.
[0051] like Figures 2 to 13As shown, the male connector 100 may include: a housing 110, a terminal assembly 120, and a cable 130. The housing 110 has a through-hole receiving cavity 111 in the axial direction. One end of the terminal assembly 120 is inserted into one end inside the receiving cavity 111, and the other end inside the receiving cavity 111 is used to insert into the female connector 200. The terminal assembly 120 is mated with the female connector 200 inside the receiving cavity 111. Terminal assembly 120 includes at least one pair of terminal blocks 121. Each terminal block 121 includes a terminal block body 1211 and a shielding sheet assembly 1212 soldered to the bottom of the terminal block body 1211. The terminal block body 1211 includes signal terminals 12111 and ground terminals 12112 arranged horizontally at intervals. The shielding sheet assembly 1212 is soldered to the bottom of the ground terminal 12112. The terminal block body 1211 and the shielding sheet assembly 1212 are integrally injection molded to form the terminal block 121. A pair of terminal blocks 121 are stacked and adjacent to each other on one side of the corresponding shielding sheet assembly 1212. Cable 130 connects to the other end of terminal assembly 120, for example, soldered to the end of terminal block body 1211 away from female connector 200. The terminal block body 1211 and the shielding sheet group 1212 are integrally injection molded to form a first plastic layer 1213. The terminal block body 1211 and the shielding sheet group 1212 are embedded in the first plastic layer 1213 on the upper and lower sides. The shielding sheet group 1212 and the bottom surface of the first plastic layer 1213 are at a predetermined distance, so that the shielding sheet groups 1212 in the stacked pair of terminal blocks 121 are spaced apart from each other.
[0052] Specifically, the cable connector with integrated shielding and terminals according to embodiments of the present invention includes a housing 110, a terminal assembly 120, and a cable 130. A pair of terminal blocks 121 in the terminal assembly 120 are integrally injection molded using a terminal block body 1211 (i.e., multiple terminals spaced apart) and a shielding sheet assembly 1212 (i.e., multiple shielding sheets spaced apart) soldered to the bottom of the terminal block body 1211. The cable 130 is connected to one end of the terminal block body 1211, and then the two terminal blocks 121 are stacked and fixed together to achieve signal transmission from the wire end to the mating end. In this pair of terminal blocks 121, the corresponding shielding sheet groups 1212 are adjacent to each other on the sides. The shielding sheet groups 1212 are welded to the bottom of the grounding terminal 12112. The shielding sheet groups 1212 are located inside the first plastic layer 1213 and do not protrude from the bottom surface of the first plastic layer 1213 (i.e., they are at a predetermined distance from the bottom surface of the first plastic layer 1312). This ensures that when the pair of terminal blocks 121 are spliced and stacked, the shielding sheet groups 1212 on the corresponding surfaces do not contact each other and are at a certain distance, thereby ensuring the signal shielding effect between the signal terminals 12111 on the pair of terminal blocks 121.
[0053] Specifically, compared to conventional connectors that shield external electrical signals by creating a ring space, the shielding plate group 1212 in this application is used for grounding, thereby shielding against static electricity and achieving a stable signal shielding effect. In other words, by setting shielding plate groups 1212 between a pair of terminal block bodies 1211 respectively, the signal terminals 1211 are isolated and shielded, preventing electromagnetic interference between the signal terminals 1211 in the terminal block body 1211, reducing crosstalk, and ensuring signal transmission quality.
[0054] In addition, the terminal block body 1211 (a plurality of signal terminals 12111 and grounding terminals 12112 arranged in a row) and the shielding plate group 1212 are integrally formed in the first plastic layer 1213, which makes the terminals and shielding plates more firmly fixed, thereby making the connector structure more stable, thereby improving reliability and durability, and can remain unaffected even in harsh environments such as humid heat, and can maintain a stable electrical connection.
[0055] It should be noted that the shielding sheet in the shielding sheet group 1212 of the present invention may be a metal part, and this application does not make specific restrictions here.
[0056] In summary, on the one hand, the cable connector of the present invention does not require the use of a retimer and expensive low-loss PCB materials, and on the other hand, the injection molding process is highly efficient and wastes less material during mass production, which can effectively reduce the overall cost.
[0057] On the other hand, PCBs are greatly affected by environmental humidity and heat. Their substrate is hygroscopic, and moisture reduces the substrate's insulation performance, leading to increased leakage current and affecting signal transmission stability. Humid and hot environments accelerate oxidation and corrosion on the PCB surface and internally. These changes increase signal loss during transmission, especially at high frequencies, where impedance mismatch is amplified, compromising signal integrity. The unstable dielectric constant of PCB materials caused by humidity and heat alters signal transmission speed and characteristic impedance, causing signal reflection and crosstalk, which have a more significant impact on signal integrity. Prolonged exposure to humidity and heat can cause PCBs to delaminate and blister, damaging their structural integrity. This not only affects mechanical performance but also alters the distributed parameters of internal circuitry (such as capacitance and inductance), causing signal distortion during transmission and further deteriorating signal integrity. Therefore, the cable connector of this invention uses an integrated injection molding method for terminals and shielding sheets. Compared to traditional PCB wiring methods, this optimizes the signal path, reduces signal attenuation and distortion, ensures signal transmission stability and integrity, and supports longer signal path transmission.
[0058] In some embodiments, such as Figure 3As shown, each terminal in the terminal block body 1211 is arranged on the first plastic layer 1213 along the width direction of the first plastic layer 1213, and multiple terminals are arranged sequentially at intervals along the length direction of the first plastic layer to form the terminal block body 1211.
[0059] Thus, on the one hand, the terminal block body 1211 can be fixed stably and reliably, and the signals between them do not interfere with each other; on the other hand, the area occupied by the first plastic layer 1213 can be fully utilized to improve the material utilization rate.
[0060] In some embodiments, such as Figure 8 As shown, a plurality of first mounting portions 12131 are formed in the upper part inside the first plastic layer 1213. The first mounting portions 12131 are arranged along the width direction of the first plastic layer 1213, and terminals are placed inside the first mounting portions 12131.
[0061] In other words, a plurality of first mounting portions 12131 are formed in the upper part inside the first plastic layer 1213 to facilitate the placement of each terminal in the terminal block body 1211 and to limit the position of each terminal. As an example, the first mounting portion 12131 may be a groove adapted to the contour of a single terminal.
[0062] In some embodiments, such as Figure 4 As shown, a first notch 12138 is also formed between adjacent first mounting portions 12131. This can reduce the amount of material used in injection molding, thereby reducing product quality and production costs. On the other hand, the high-density connection design of traditional PCBs generates a lot of heat. If heat dissipation is not timely, it will affect the stability and performance of the system and increase the risk of failure. The first notch 12138 can increase the heat dissipation area on the surface of the terminal block 121 and improve heat dissipation performance.
[0063] In some embodiments, such as Figure 4 , Figure 6 and Figure 8 As shown, on the side wall of the first plastic layer 1213 along the length direction, an embedding groove 12133 is provided for each first mounting part 12131, which penetrates the side wall along the thickness direction. The embedding groove 12133 is used to embed the grounding terminal of the terminal.
[0064] Specifically, an embedding groove 12133 extending through the thickness direction is provided on the side wall of the first plastic layer 1213 along the length direction. Each embedding groove 12133 connects the interior of the first mounting part 12131 with the outside. On the one hand, it can embed and limit the grounding end of the terminal to ensure the reliability of the terminal fixation. On the other hand, it can facilitate the heat dissipation of the terminal.
[0065] In some embodiments, such as Figure 6As shown, a plurality of second mounting portions 12132 are formed in the lower part inside the first plastic layer 1213, and a shielding sheet is placed inside the second mounting portion 12132.
[0066] Specifically, the second mounting part 12132 may be a groove that matches the contour of a single shielding sheet in the shielding sheet group 1212. The second mounting part 12132 is located below the first mounting part 12131 and is used to place each shielding sheet in the shielding sheet group 1212 and to limit the position of each shielding sheet.
[0067] In some embodiments, such as Figure 6 As shown, a second notch 12139 is also formed between adjacent second mounting portions 12132. This can reduce the amount of material used in injection molding, thereby reducing product quality and production costs. On the other hand, the second notch 12139 connects the bottom surface of the terminal block 121 to the outside, which can increase the heat dissipation area of the terminal block 121 surface and improve heat dissipation performance.
[0068] In some embodiments, such as Figure 8 As shown, the shielding sheet includes a shielding sheet body 12121 and a plurality of pins 12122 extending out of the surface of the shielding sheet body 12121. The shielding sheet body 12121 is disposed inside the second mounting portion 12132, and one end of the pins 12122 extends through the second mounting portion 12132 into the interior of the first mounting portion 12131. At least one pair of pins 12122 at the same straight position along the width direction of the first plastic layer 1213 are connected to the bottom of the signal terminal of a single terminal.
[0069] Specifically, the shielding plate body 12121 can be a rectangular plate, with multiple pins 12122 arranged in a matrix on the shielding plate body 12121. Each pin 12122 protrudes from the surface of the shielding plate body 12121 to facilitate soldering to the signal terminal of a single terminal by extending through the second mounting portion 12132 into the interior of the first mounting portion 12131. Pins 12122 (at least one pair, and possibly three or more) on each shielding plate body 12121 at the same straight line position along the width direction of the first plastic layer 1213 are used to solder the signal terminal of a single terminal, ensuring the reliability of the connection between the shielding plate body 12121 and the single terminal. Each shielding plate body 12121 may include multiple sets of pins 12122 along the width direction of the first plastic layer 1213, and these multiple sets of pins 12122 correspondingly connect to multiple terminals on the terminal block body 1211.
[0070] In some embodiments, such as Figures 4-6As shown, a first limiting structure is also formed on one side of the bottom of the first plastic layer 1213 corresponding to the embedded groove 12133. The first limiting structure includes a dovetail groove group 12134 and a tenon group 12135 arranged sequentially along the length direction of the bottom of the first plastic layer 1213. A pair of terminal blocks 121 are connected by the dovetail groove group 12134 and the tenon group 12135 at the bottom of the first plastic layer 1213.
[0071] In other words, the dovetail groove assembly 12134 and the tenon assembly 12135 in the first limiting structure are respectively provided on one side of the bottom of the first plastic layer 1213 along the length direction (for example, the side of the bottom of the first plastic layer 1213 away from the cable 130). Specifically, the dovetail groove assembly 12134 includes a plurality of dovetail grooves spaced apart along the length direction, the opening width of which gradually increases from the outside to the inside, and the plurality of dovetail grooves can be provided on the left side of the side of the bottom of the first plastic layer 1213 along the length direction. The tenon assembly 12135 includes a plurality of tenons spaced apart along the length direction, and the plurality of tenons can be provided on the right side of the side of the bottom of the first plastic layer 1213 along the length direction, the shape of which is adapted to the dovetail grooves to ensure a firm and reliable connection. The dovetail grooves 12134 and tenon 12135 on the sides of each pair of terminal blocks 121 are staggered and matched, with precise positioning, ensuring that the structure of the terminal assembly 120 formed can be adapted to the internal space of the receiving cavity 111. On the other hand, it also makes the terminal assembly 120 embedded in the receiving cavity 111 after plastic sealing more secure.
[0072] In some embodiments, such as Figures 5-6 As shown, a second limiting structure is also formed on the side of the bottom of the first plastic layer 1213 away from the first limiting structure. The second limiting structure includes a set of countersunk holes 12136 and a set of guide posts 12137 arranged sequentially along the length of the bottom of the first plastic layer 1213. A pair of terminal blocks 121 are connected by the guide post set 12137 through the countersunk holes 12136 at the bottom of the first plastic layer 1213.
[0073] In other words, a second limiting structure is provided on the side of the bottom of the first plastic layer 1213 opposite to the first limiting structure. This second limiting structure further ensures the precise and reliable connection between the pair of terminal blocks 121. Specifically, the countersunk hole assembly 12136 includes multiple countersunk holes spaced apart along the length direction, and multiple dovetail grooves can be provided on the left side of the other side of the bottom of the first plastic layer 1213 along the length direction. The guide post assembly 12137 includes multiple guide posts (e.g., staggered guide posts) spaced apart along the length direction. These guide posts can be provided on the right side of the other side of the bottom of the first plastic layer 1213 along the length direction. The guide posts and countersunk holes are interference-fitted to ensure a stable and reliable connection.
[0074] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 110 may include a front housing 112 and a rear housing 113. The front housing 112 has an internal receiving cavity 111. One end of the terminal assembly 120 is inserted into the receiving cavity and integrally injection molded with the front housing 112. The terminal assembly 120 is connected to the receiving cavity 111 via a second plastic layer 150 formed by injection molding. The second plastic layer 150 integrally molds the terminal assembly 120 with the front housing 112, further ensuring the stability and robustness of the terminal assembly 120 structure.
[0075] The rear housing 113 is snapped onto the lower part of the front housing 112 near the end of the cable 130, and the rear housing 113 supports the bottom of the second plastic layer 150 exposed in the receiving cavity 111. In other words, the rear housing 113 is detachably connected to the front housing 112 by a snap-fit structure, and its connection to the lower part of the front housing 112 near the end of the cable 130 facilitates the provision of holding force to the end of the second plastic layer 150 exposed in the receiving cavity 111, thereby providing holding force to the terminal assembly 120 and the cable 130, ensuring that the terminal assembly 120 and the cable 130 are tightly fitted and connected to the housing 110, and ensuring the stability of the overall structure.
[0076] In addition, a mounting groove 1121 is formed on the top surface of the front cover 112 for connecting the snap-fit assembly 140.
[0077] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
