[0040] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, 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 utility model, "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 this utility model, and should not be construed as limiting this utility model.

[0041] like Figures 1 to 8 As shown, this utility model provides a cable connector integrating grounding and shielding functions, including a male connector 100 and a female connector 200, which are interlocked. The male connector 100 may include a housing 110, a terminal assembly 120, and a cable 130. One end of the terminal assembly 120 is inserted into the housing 110. The terminal assembly 120 includes a shielding block 121, a plurality of grounding terminals 122, and a plurality of signal terminals 123. The plurality of grounding terminals 122 are spaced apart on the upper and lower surfaces of the shielding block 121, and signal terminals 123 are disposed between adjacent grounding terminals 122 on the upper and lower surfaces of the shielding block 121. The shielding block 121, the plurality of grounding terminals 122, and the plurality of signal terminals 123 are integrally injection molded to form the terminal assembly 120. The cable 130 connects to the other end of the terminal assembly 120.

[0042] Specifically, the cable connector of this utility model, which integrates grounding and shielding functions, uses a shielding block 121, multiple grounding terminals 122, and multiple signal terminals 123 integrally injection molded to form a terminal assembly 120 to realize signal transmission from the cable 130 to the mating end. The grounding terminals 122 are spaced apart on the upper and lower surfaces of the shielding block 121, and signal terminals 123 are arranged between adjacent grounding terminals 122 on the same side. Thus, by shielding the signal terminals 123 on both sides through the shielding block 121, electromagnetic interference and radio frequency interference between the signal terminals 123 during signal transmission can be effectively reduced.

[0043] In other words, the cable connector of this invention can improve the anti-interference capability of signals, reduce the bit error rate, and enable high-speed signals to maintain better integrity during transmission.

[0044] In some embodiments, such as Figure 4 As shown, the shielding block 121 is rectangular, and a plurality of grounding terminals 122 are formed on the upper or lower surface of the shielding block 121 along the width direction of the shielding block 121. Preferably, the plurality of grounding terminals 122 are integrally formed with the shielding block 121.

[0045] As an example, multiple grounding terminals 122 are correspondingly disposed on both sides of the shielding block 121, and each grounding terminal 122 extends along the width direction of the shielding block 121. By forming multiple grounding terminals 122 on the upper and lower sides of the shielding block 121 in an integral molding manner, compared with the traditional form where the grounding terminals and shielding plates are separate, they are combined into a single part, which simplifies the structure and assembly process and provides better shielding effect.

[0046] It should be noted that the shielding block 121 and the grounding terminal 122 in this application are made of metal. The shielding plate group in this application is used for grounding, thereby shielding against static electricity and achieving the effect of stable signal shielding.

[0047] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, a first receiving groove 124 is formed between adjacent grounding terminals 122 on the upper or lower surface of the shielding block 121, and a signal terminal 123 is disposed in the first receiving groove 124.

[0048] In other words, a signal terminal 123 is provided in the first receiving groove 124 formed between adjacent grounding terminals 122 on one side surface of the shielding block 121, so that the signal terminal 123 and the grounding terminal 122 are on the same reference plane, and the structure is more stable and reliable after integral injection molding.

[0049] Preferably, both ends of the signal terminal 123 along the length direction are located inside the side of the shielding block 121 along the length direction.

[0050] This ensures that the signal terminal 123 is completely covered by the shielding block 121, thus ensuring the effectiveness of the shielding.

[0051] In some embodiments, such as Figure 4 and Figure 8 As shown, a shielding block 121, multiple grounding terminals 122 and multiple signal terminals 123 are integrally injection molded to form a first plastic layer 125, and the shielding block 121, multiple grounding terminals 122 and multiple signal terminals 123 are disposed inside the first plastic layer 125.

[0052] As an example, after the shielding block 121, multiple grounding terminals 122 and multiple signal terminals 123 are integrally injection molded, the grounding terminals 122 and signal terminals 123 on the corresponding side are exposed on the surface of the first plastic layer 125 to facilitate heat dissipation.

[0053] In some embodiments, a second receiving groove (not shown) parallel to the upper and lower surfaces of the first plastic layer 125 is formed inside the first receiving layer 125, and the shielding block 121 is placed inside the second receiving groove.

[0054] In other words, after the terminal assembly 120 is integrally injection molded, the shielding block 121 is wrapped inside the first plastic layer 125, for example, it can be accommodated in the second accommodating groove inside the first plastic layer 125 to ensure the stability of the overall structure.

[0055] In some embodiments, such as Figure 4 and Figure 5 As shown, a third receiving groove 1251 and a fourth receiving groove 1252 perpendicular to the second receiving groove are formed inside the first plastic layer 125. The third receiving groove 1251 and the fourth receiving groove 1252 respectively penetrate the upper and lower surfaces of the first plastic layer 125. The third receiving groove 1251 and the fourth receiving groove 1252 respectively accommodate the grounding terminal 122 and the signal terminal 123.

[0056] In other words, the interior of the first plastic layer 125 is provided with a third receiving groove 1251 and a fourth receiving groove 1252 that are perpendicular to the second receiving groove. Thus, the third receiving groove 1251 and the fourth receiving groove 1252 are connected to the two sides of the first plastic layer 125, which facilitates heat dissipation of the terminals when accommodating the grounding terminal 122 and the signal terminal 123 respectively.

[0057] In addition, a connecting groove 1253 is formed on the adjacent sides of the third receiving groove 1251 and the fourth receiving groove 1252, which connects the third receiving groove 1251 and the fourth receiving groove 1252, further improving the heat dissipation performance of the terminal assembly.

[0058] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, a protrusion 1211 is formed on the side of the shielding block 121 along the length direction.

[0059] Specifically, the protrusion 1211 extends along the side of the shielding block 121 in the length direction and protrudes from the side of the shielding block 121, so as to separate the upper and lower layers of the cable 130 when one end of the terminal assembly 120 is connected to the cable 130, so as to avoid misconnection.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, the housing 110 may include a front housing 111 and a rear housing 112. The front housing 111 has an internal receiving cavity. One end of the terminal assembly 120 is inserted into the receiving cavity and integrally injection molded with the front housing 111. The terminal assembly 120 is connected to the receiving cavity through a second plastic layer 150 formed by injection molding. The second plastic layer 150 integrally molds the terminal assembly 120 with the front housing 111, further ensuring the stability and robustness of the terminal assembly 120 structure.

[0061] The rear housing 112 is snapped onto the lower part of the front housing 111 near the end of the cable 130, and the rear housing 112 supports the bottom of the end of the second plastic layer 150 exposed in the receiving cavity. That is, the rear housing 112 can be detachably connected to the front housing 111 by a snap-fit ​​structure, and its connection to the lower part of the front housing 111 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, 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.

[0062] In addition, such as Figure 2 As shown, a mounting groove 113 is also formed on the top surface of the front shell 111 for connecting the snap-fit ​​assembly 140.

[0063] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
