[0002] Existing electrical connector assemblies include electrical connectors and corresponding mating connectors, integrating a signal cable connector and a power cable connector into a single cable. This allows for electrical connections, including audio / video signal transmission and power transmission, between video source devices (such as computers and game consoles) and display devices (such as monitors and projectors). The ability to shield against interference during data transmission determines the quality of signal transmission from the electrical connector.

[0003] Existing cable connectors, such as the cable connector provided in the earlier patent with patent application number CN101011332765.7, have a shielding plate set inside the first shielding shell. The shielding plate is made of metal material and is a one-piece structure. One end of the shielding plate is interference-fitted into the first notch and the second notch of the first shielding shell to realize the electrical connection between the shielding plate and the first shielding shell, thereby increasing the grounding area and improving the shielding effect.

[0004] However, due to the presence of a first notch and a second notch in the first shielding housing of the cable connector, the contact wall of the notch in contact with the shielding sheet is prone to deformation and warping, resulting in poor contact with the shielding sheet and affecting the shielding effect. Summary of the Invention

[0043] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figure 1 As shown, this embodiment provides a cable connector, which includes a cable 10 and an electrical connector connected to one end of the cable 10. The electrical connector has a good shielding effect, thereby ensuring the data transmission effect of the cable connector.

[0045] Specifically, such as Figure 3 and Figure 4 As shown, the cable 10 includes a core wire 102, an inner insulation layer 103, a shielding layer 101, and an outer insulation layer 104. The inner insulation layer 103 is sleeved on the outside of the core wire 102, the shielding layer 101 is sleeved on the outside of the inner insulation layer 103, and the outer insulation layer 104 is sleeved on the outside of the shielding layer 101.

[0046] like Figure 2As shown, the electrical connector provided in this embodiment includes a terminal module 2 and a shielding shell 3. The terminal module 2 includes a conductive module and a grounding plate 22. One end of the conductive module is used to connect to the mating conductive terminal of the mating connector (not shown in the figure), and the other end is connected to the core wire 102 of the cable 10. The shielding shell 3 includes a first shell 31 and a grounding connector 32 integrally formed with the first shell 31. The first shell 31 is disposed on the outside of the terminal module 2. One end of the grounding plate 22 abuts against the inner wall of the first shell 31, and the other end of the grounding plate 22 is used to connect to the mating grounding terminal of the mating connector. The grounding connector 32 is connected to the shielding layer 101 of the cable 10.

[0047] The electrical connector provided in this embodiment has a conductive module used to realize the electrical connection between the mating connector and the core wire 102 of the cable 10 to achieve data transmission. One end of the grounding piece 22 abuts against the inner wall of the first housing 31, and the other end of the grounding piece 22 is used to connect to the mating grounding terminal of the mating connector. The first housing 31 is connected to the grounding connector 32, which is connected to the shielding layer 101 of the cable 10, thus playing the role of grounding and shielding interference. The first housing 31 and the grounding connector 32 are integrally formed, with high connection strength. Moreover, the grounding piece 22 abuts against the inner wall of the first housing 31, without the need to open a notch as in the prior art, thereby ensuring the reliability of the connection between the grounding piece 22 and the shielding shell 3, and making the grounding and shielding effect better.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, the shielding shell 3 also includes a second outer shell 33, one end of which is sleeved on the outside of the cable 10, and the other end is sleeved on the outside of the first shell 31. That is, the second outer shell 33 covers the outside of the connection between the cable 10 and the terminal module 2.

[0049] Specifically, such as Figure 2 and Figure 5 As shown, the electrical connector also includes an insulator 4, with a portion of the conductive module disposed within the insulator 4, and a first housing 31 covering the outside of the insulator 4. The insulator 4 has a through-slot 43 extending along a first direction, through which a portion of the conductive module passes. An opening 44 communicating with the outside is formed on the inner wall of the through-slot 43, and one end of the grounding piece 22 passes through the opening 44 and abuts against the inner wall of the first housing 31.

[0050] like Figure 5 and Figure 6 As shown, a first positioning protrusion 41 is provided on the outer side wall of the insulator 4, and a first positioning groove 3113 is provided on the side wall of the first housing 31. The insulator 4 is disposed in the first housing 31, and the first positioning protrusion 41 is positioned in the first positioning groove 3113 to ensure the firmness of the connection between the two.

[0051] Specifically, such as Figure 7 and Figure 8 As shown, the conductive module includes a first module 211 and a second module 212, which are interconnected, and at least a portion of the grounding piece 22 is disposed between the first module 211 and the second module 212.

[0052] For more details, see [link to relevant documentation] Figure 7 and Figure 8 The first module 211 includes a first insulating fixing block 2111 and a plurality of first conductive terminals 2112 fixed on the first insulating fixing block 2111. In this embodiment, the plurality of first conductive terminals 2112 are embedded in the first insulating fixing block 2111, and the plurality of first conductive terminals 2112 are distributed at intervals along a second direction, the second direction being perpendicular to the first direction. Correspondingly, the second module 212 includes a second insulating fixing block 2121 and a plurality of second conductive terminals 2122 fixed on the second insulating fixing block 2121. In this embodiment, the plurality of second conductive terminals 2122 are embedded in the second insulating fixing block 2121. The first insulating fixing block 2111 is connected to the second insulating fixing block 2121, and the plurality of second conductive terminals 2122 are distributed at intervals along the second direction.

[0053] Specifically, see [link to relevant documentation] Figure 7 and Figure 8 One of the first insulating fixing block 2111 and the second insulating fixing block 2121 is provided with a plurality of first positioning posts 2125, and the other is provided with a plurality of second positioning holes. The plurality of first positioning posts 2125 are correspondingly arranged in the plurality of second positioning holes to securely fix the first insulating fixing block 2111 and the second insulating fixing block 2121. In this embodiment, the first insulating fixing block 2111 has two second positioning holes, and the second insulating fixing block 2121 is provided with two first positioning posts 2125. A portion of the grounding piece 22 is sandwiched between the first insulating fixing block 2111 and the second insulating fixing block 2121. The grounding piece 22 has two first positioning holes 2211. The first positioning posts 2125 pass through the first positioning holes 2211 and then into the second positioning holes, thus simultaneously fixing the grounding piece 22.

[0054] More specifically, such as Figure 5 and Figure 8 As shown, the first insulating fixing block 2111 and the second insulating fixing block 2121 are both provided with a plurality of second positioning protrusions 2113, and the insulator 4 is provided with a plurality of second positioning grooves 42. Each second positioning protrusion 2113 is correspondingly disposed in a second positioning groove 42, which ensures the firmness of the connection between the first insulating fixing block 2111 and the second insulating fixing block 2121 and the insulator 4.

[0055] Specifically, the grounding plate 22 includes a main body 221, a plurality of grounding terminals 222, and two elastic abutment portions 223. One end of each grounding terminal 222 is connected to one side of the main body 221, and the other end is used to connect to the mating grounding terminal of a mating connector. The plurality of grounding terminals 222 are distributed sequentially at intervals along a second direction. The two elastic abutment portions 223 are respectively disposed at both ends of the side of the main body 221 opposite to the grounding terminals 222, and the two elastic abutment portions 223 elastically abut against two opposite inner walls of the first housing 31. In this embodiment, the elastic abutment portions 223 abut against the inner wall of the first housing 31 after passing through the notch 44. Specifically, two first positioning holes 2211 are provided on the main body 221. The grounding plate 22 is made of metal material and is an integrally formed structure.

[0056] More specifically, one end of each of the two elastic abutment portions 223 is connected to the main body portion 221, and the other end extends obliquely in a direction away from each other. This arrangement achieves elastic abutment between the elastic abutment portions 223 and the first housing 31, ensuring the stability of their electrical connection.

[0057] like Figure 7 and Figure 8 As shown, the length of the second insulating fixing block 2121 in the first direction is greater than the length of the first insulating fixing block 2111. That is, the portion of the first insulating fixing block 2111 that is connected to the second insulating fixing block 2121 has a portion that extends beyond the first insulating fixing block 2111. The ends of the first conductive terminal 2112 and the second conductive terminal 2122 facing the cable 10 are housed within the other portion of the second insulating fixing block 2121. The multiple core wires 102 of the cable 10 are respectively soldered to the ends of the first conductive terminal 2112 and the second conductive terminal 2122.

[0058] Specifically, such as Figure 6 As shown, the grounding connector 32 includes a first connecting portion 321 and a second connecting portion 322. One end of the first connecting portion 321 is connected to the side wall of the first housing 31, and the other end extends toward the interior of the first housing 31 and is connected to the second connecting portion 322. The second connecting portion 322 is connected to the shielding layer 101 of the cable 10. The first connecting portion 321 is used to position the second connecting portion 322 on the passage of the cable 10 so as to facilitate connection with the shielding layer 101 of the cable 10.

[0059] For more details, see [link to relevant documentation] Figure 6The first housing 31 includes a sleeve-like structure and an extension plate 312. The sleeve-like structure includes two opposing first side plates 3111 and second side plates 3112. The extension plate 312 is connected to one end of the first side plate 3111, and the grounding connector 32 is connected to the end of the second side plate 3112 near the extension plate 312. The conductive module extends from inside the sleeve-like structure to the side of the extension plate 312. Since the first housing 31 and the grounding connector 32 are integrally formed, their connection strength is high. There is no need to provide a housing around the grounding connector 32 to ensure the firmness of fixing the grounding connector 32. That is, it saves the need to provide an extension plate to form a housing with the extension plate 312 on the second side plate 3112 and the other two side plates, thus saving materials. In this embodiment, the portion of the second insulating fixing block 2121 corresponding to the first insulating fixing block 2111 is disposed inside the sleeve-like structure of the first housing 31, and the portion extending beyond the first insulating fixing block 2111 is disposed on the extension plate 312.

[0060] Specifically, see [link to relevant documentation] Figure 6 The grounding connector 32 includes two first connecting portions 321 and a second connecting portion 322 with a U-shaped structure. The two ends of the U-shaped structure are connected one-to-one with the two first connecting portions 321. This structure ensures a secure connection between the grounding connector 32 and the first housing 31. Figure 6 and Figure 8 As shown, one end of the connecting cable 10 of the first conductive terminal 2112 and the second conductive terminal 2122 is located in the U-shaped space of the second connecting part 322. The structure is reasonably arranged and facilitates the connection with the cable 10.

[0061] More specifically, such as Figure 6 and Figure 8 As shown, the conductive module is provided with a receiving groove 2123, and the second connecting part 322 is received within the receiving groove 2123. This arrangement further ensures the firmness of the grounding connector 32. In this embodiment, the second insulating fixing block 2121 of the second module 212 is provided with a receiving groove 2123.

[0062] For further details, please refer to [link / reference]. Figure 6 and Figure 8 The grounding connector 32 also includes several positioning portions 323, which are connected to the end of the second connector 322 opposite to the first connector 321. The bottom of the receiving groove 2123 has several positioning grooves 2124, and the positioning portions 323 are correspondingly disposed within the positioning grooves 2124. This arrangement further improves the firmness of the grounding connector 32. In this embodiment, each of the three sides of the U-shaped second connector 322 is provided with a sheet-like positioning portion 323. Correspondingly, three positioning grooves 2124 are provided, and they are strip-shaped grooves.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention.
