[0002] LVDS high-frequency electrical connectors are increasingly widely used in various electronic devices. An LVDS high-frequency electrical connector generally consists of an elongated insulating body and conductive terminals fixed inside the insulating body. While this type of LVDS high-frequency electrical connector usually has a shielding shell on the outside of the insulating body, this shielding shell is typically flush against the outside of the insulating body and lacks a gripping structure. This makes insertion and removal of this type of high-frequency electrical connector difficult and inconvenient to use.

[0003] In view of this, it is necessary to improve the existing high-frequency electrical connectors to solve the above problems. Utility Model Content

[0025] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0026] like Figures 1 to 9 As shown, this utility model provides a high-frequency electrical connector 100 with a shielding structure, comprising:

[0027] The insulating body 1 extends longitudinally;

[0028] A plurality of conductive terminals are provided and arranged and fixed within the insulating body 1 along the extending direction of the insulating body 1;

[0029] The shielding outer shell 2 covers the outside of the insulating body 1;

[0030] The extension member 3 includes a fixed part 4 and a suspended part 5 that are connected to each other. The fixed part 4 is fixedly connected to the outer surface of the shielding shell 2, and the suspended part 5 is spaced apart from the outer surface of the shielding shell 2 to form a gap 10.

[0031] Therefore, by adding the extension member 3 to the outside of the shielding shell 2, the extension member 3 includes a fixing part 4 and a suspended part 5. The fixing part 4 is fixedly connected to the outer surface of the shielding shell 2, so that the extension member 3 can be fixed to the shielding shell 2 and together they form an integrated shielding cover assembly, which has the function of shielding signals and facilitates the installation of a pull strap. At the same time, the suspended part 5 is spaced apart from the outer surface of the shielding shell 2 to form a gap 10, so that a pull strap (not shown) can be inserted into the gap 10 to form a gripping structure, thereby facilitating gripping and enabling repeated insertion and removal of the electrical connector 100.

[0032] The suspended portion 5 also extends longitudinally, and there are two fixed portions 4 located at both ends of the suspended portion 5. Preferably, in this embodiment, the gap height between the suspended portion 5 and the adjacent outer surface of the shielding shell 2 is in the range of 0.05-0.5mm.

[0033] like Figure 1 As shown in the embodiment, the extension member 3 is longitudinally elongated and fixed above the insulating body 1. A fixing part 4 is provided at each end of the suspended portion 5, thus the extension member 3 can be firmly fixed to the shielding shell 2, and the suspended portion 5 is not easily deformed. The distance 10 between the suspended portion 5 and the outer surface of the shielding shell 2 is stable, facilitating the insertion of a pulling strap and making the pulling force more balanced during the pulling operation.

[0034] like Figure 1 As shown, the shielding shell 2 of the high-frequency electrical connector 100 with shielding structure in this utility model forms a forward-opening opening 20. The conductive terminal is fixed inside the insulating body 1. During operation, the mating connector can be inserted through the opening 20 to contact the conductive terminal.

[0035] Of course, if the suspended part 5 is of other shapes, and multiple fixing parts 4 are provided, as long as the suspended part 5 is spaced apart from the outer surface of the shielding shell 2, the purpose of this utility model can be achieved.

[0036] like Figures 8 to 9As shown, the fixing part 4 includes a base plate 41, an inclined part 42 extending upward from the base plate 41, and a limiting part formed by bending downward from the base plate 41. The inclined part 42 is connected to the suspended part 5. In this embodiment, the base plate 41 has an irregular shape, and the inclined part 42 extends upward from the base plate 41, so that the suspended part 5 is generally higher than the base plate 41. Furthermore, a gap 10 can be formed between the suspended part 5 and the outer surface of the shielding shell 2. In this embodiment, laser welding is performed to fix the base plate 41 to the shielding shell 2.

[0037] As mentioned above, there are two fixing parts 4, which are respectively fixed to both ends of the suspended part 5, so that the extension part 3 is in the shape of a bridge, with the two fixing parts 4 at both ends fixed to the shielding shell 2, and the suspended part 5 in the middle protruding upward.

[0038] In this specific embodiment, the substrate 41 is attached to the upper surface of the shielding shell 2, and the limiting part is formed by bending downward from the substrate 41. The limiting part stops the side surface of the shielding shell 2, which makes the welding between the fixing part 4 and the shielding shell 2 more precise and stable. Of course, if the limiting part is set in other positions, such as the limiting part extending horizontally outward from the side of the substrate 41, the purpose of the present invention can also be achieved. In this embodiment, when the shielding shell 2 and the extension member 3 are connected, the limiting part plays a stopping role.

[0039] Specifically, such as Figure 4 As shown, the front end of the substrate 41 is recessed inward to form a first notch 43, and the front end of the substrate 41 is divided into a first front end surface 431 and a second front end surface 432, wherein the second front end surface 432 is disposed near the suspended part 5; the limiting part includes a first limiting part 441, which is formed by bending downward from the first front end surface 431.

[0040] The front end of the substrate 41, that is, the end of the substrate 41 facing the opening 20 of the shielding shell 2, has a first notch 43 recessed at the front end to divide the front end of the substrate 41 into two segments. The first limiting portion 441 is bent downward only from the first front end surface 431. Of course, if the first limiting portion 441 is formed by bending downward from the entire front end of the substrate 41, or by bending downward from the second front end surface 432, the purpose of this utility model can be achieved.

[0041] like Figure 9As shown, the rear end of the substrate 41 is recessed inward to form a second notch 45, and the rear end of the substrate 41 is divided into a first rear end surface 451 and a second rear end surface 452, wherein the second rear end surface 452 is disposed near the suspended portion 5; the limiting portion includes a second limiting portion 442, which is formed by bending downward from the first rear end surface 451.

[0042] As described above, the substrate 41 has an irregular shape, but the front and rear ends of the substrate 41 are generally straight and parallel, and the length of the rear end of the substrate 41 is greater than the length of the front end. A second notch 45 is formed on the rear end of the substrate 41 to divide the rear end of the substrate 41 into two segments. The overall length of the second rear end face 452 is actually approximately the same as the length of the front end of the substrate 41. The first rear end face 451 is shorter, and the second limiting portion 442 is formed by bending downwards from the first rear end face 451. Similarly, if the second limiting portion 442 is formed by bending downwards from the rear end of the substrate 41 as a whole, or by bending downwards from the second rear end face 452, the purpose of this utility model can also be achieved.

[0043] In this embodiment, the limiting parts are all located at the front or rear end of the substrate 41, and provide front-to-back blocking and limiting. Of course, if the limiting parts are located at the side end of the substrate 41, they are also within the protection scope of this utility model.

[0044] like Figure 5 As shown, since the extension member 3 is provided with the limiting part, the shielding shell 2 is also provided with a corresponding locking part that is adapted to the limiting part.

[0045] Specifically, the shielding shell 2 includes an upper shell portion 21 and a lower shell portion 22 that are arranged opposite each other in height, and the substrate 41 is attached to the upper shell portion 21; the upper shell portion 21 includes an upper shell plate 211 and a first locking member 212 formed by bending downward from the front end of the upper shell plate 211 near the side, and the first limiting portion 441 is stopped on the first locking member 212; the extension area of ​​the first locking member 212 is larger than that of the first limiting portion 441.

[0046] The shielding outer shell 2 includes an upper shell portion 21 and a lower shell portion 22, which are snap-fitted together to form a front-facing opening 20. The upper shell plate 211 of the upper shell portion 21 is generally horizontal, allowing it to abut against the base plate 41 of the fixing plate, while the suspended portion 5 is spaced apart from the upper shell plate 211. Figure 2 As shown, the first locking member 212 is located at the front end of the upper shell plate 211 near the side, corresponding in position to the first limiting part 441. The extension area of ​​the first locking member 212 is larger than that of the first limiting part 441.

[0047] Furthermore, the suspended portion 5 extends longitudinally and is parallel to the upper surface of the upper shell portion 21, i.e., the upper shell plate 211, so that the gap 10 formed between the suspended portion 5 and the upper shell plate 211 is provided through the front and back to facilitate the installation of the pull strap.

[0048] In addition, such as Figure 2 and Figure 5 As shown, the first locking member 212 is also provided with a slot 2120, which is used to engage with the lower housing part 22. After the upper housing part 21 and the lower housing part 22 are engaged and fixed, the first limiting part 441 is positioned and overlaps the first locking member 212. The first limiting part 441 is located entirely above the slot 2120 and does not obstruct the slot 2120, so as to prevent affecting the disassembly between the upper housing part 21 and the lower housing part 22.

[0049] Of course, such as Figure 5 As shown, the upper housing portion 21 further includes an extension portion 213 extending outward from a portion of the side of the upper housing plate 211, and a second locking member 214 formed by bending downward from the rear side of the extension portion 213. The second limiting portion 442 overlaps on the second locking member 214. The width of the second locking member 214 is smaller than that of the second limiting portion 442, and the length of the second locking member 214 is greater than that of the second limiting portion 442.

[0050] like Figure 5 As shown, the extension 213 extends horizontally outward from a portion of the side edge of the upper shell plate 211, so that the extension 213 and the upper shell plate 211 are located on the same plane, and the extension 213 is generally square. The second locking member 214 is formed by bending downward from the rear side of the extension 213, and the second locking member 214 and the first locking member 212 are generally parallel to each other in position. Figure 7 As shown, the second limiting part 442 is relatively wide, so it can better cover the second locking member 214, making the locking between the two more precise.

[0051] Furthermore, the extension 213 of the upper housing portion 21 is mainly for engaging with the insulating body 1, such as... Figure 5 As shown, the rear side of the extension 213 is bent downward to form a second locking member 214, and the front side of the extension 213 is also bent downward to form a locking part 215. The locking part 215, the extension 213, and the second locking member 214 form a bayonet that cooperates with the insulating body 1, so that the upper housing part 21 can be stably fixed on the insulating body 1.

[0052] like Figure 8 and Figure 9As shown, the side of the substrate 41 is connected to the inclined portion 42, and the inclined portion 42 is located at a rearward position on the side of the substrate 41. Since the inclined portion 42 is connected to the suspended portion 5, the suspended portion 5 is also located at a rearward position on the side of the substrate 41. Therefore, the middle section of the suspended portion 5 of the extension member 3 is positioned relatively rearward, and several snap-fit ​​structures on the upper housing portion 21 can be exposed outward, facilitating better connection and fixation between the electrical connector 100 and the mating connector.

[0053] like Figure 8 As shown, the suspended portion 5 extends along the longitudinal direction and includes a front side 51 and a rear side 52. The rear side 52 is recessed inward to form a third notch 53. The third notches 53 are arranged in pairs and spaced apart from each other.

[0054] As described above, the suspended portion 5 is generally square and includes a front side 51 and a rear side 52. The third recesses 53 are arranged in pairs on the rear side 52. In this specific embodiment, there are two pairs of third recesses 53, which are separated from each other. A strip connecting portion 54 is formed between each pair of third recesses 53 to connect with the metal strip. By providing the third recesses 53, the removal of the metal strip is more convenient and faster.

[0055] Thus, the suspended part 5 and the upper surface of the shielding shell 2, namely the upper shell plate 211 of the upper shell part 21, are parallel to each other, and the gap 10 extends through the front and back, thereby facilitating the installation of the pull strap on the outside of the suspended part 5.

[0056] In this embodiment, during the assembly process, the conductive terminals of the electrical connector 100 are first combined by molding to form an insulating body 1 with conductive terminals. Then, the shielding shell 2 and the extension 3 are fixed by laser welding to form a shielding assembly. Finally, the shielding assembly is fastened to the outside of the insulating body 1 to form a complete high-frequency electrical connector 100 with a shielding structure.

[0057] Therefore, in summary, the high-frequency electrical connector 100 with a shielding structure of this utility model adds the extension member 3 to the outside of the shielding shell 2. The extension member 3 includes a fixing part 4 and a suspended part 5. The fixing part 4 is fixedly connected to the outer surface of the shielding shell 2, so that the extension member 3 can be fixedly connected to the shielding shell 2 and together they form an integrated shielding assembly, which has the function of shielding signals. At the same time, the suspended part 5 is spaced apart from the outer surface of the shielding shell 2 to form a gap 10, so that a pull strap can be inserted into the gap 10 to form a gripping structure, thereby facilitating multiple insertions and removals of the high-frequency electrical connector 100.

[0058] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0059] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
