Description

Technical Field

[0001] This invention relates to the field of signal transmission device technology, and in particular to an electrical connector. Background Technology

[0002] Currently, with the continuous improvement of communication technology, the requirements for data transmission rate and quality are also increasing. High-speed electrical connectors are widely used in the communication field. They are a common type of connector used in large communication equipment, ultra-high-performance servers and supercomputers, industrial computers, and high-end storage devices. Typically, high-speed electrical connectors used for high-speed signal transmission generally include a pair of female connectors and a male connector that interlock. Due to factors such as inadequate structural design, existing high-speed electrical connectors suffer from poor shielding, leading to significant crosstalk between signals and affecting data transmission quality. Summary of the Invention

[0003] Therefore, it is necessary to provide an electrical connector that addresses the problems of poor shielding, weak crosstalk resistance, and poor data transmission quality in existing technologies.

[0004] This application provides an electrical connector, the electrical connector comprising:

[0005] A female connector, comprising at least two female connection components arranged side-by-side, each female connection component including a female shield and a female signal terminal disposed on the female shield; and

[0006] A male connector includes at least two male connection components arranged side by side, each corresponding to a female connection component. Each male connection component includes a male shield and a male signal terminal disposed on the male shield. The male shield and the female shield are nested and connected to form an omnidirectional closed structure. The male signal terminal is in electrical contact with the female signal terminal and is enclosed within the omnidirectional closed structure.

[0007] When using the electrical connector described above, the female connector and male connector are mated together. The female connector includes at least two female connecting components, which are correspondingly mated with at least two male connecting components of the male connector, ensuring a good electrical connection. Specifically, the male shielding shell of each male connecting component is nested with the corresponding female shielding shell of the female connecting component. Simultaneously, the female signal terminals installed within the female shielding shells and the male signal terminals installed within the male shielding shells maintain good contact, enabling high-speed signal transmission. Because the male and female shielding shells are nested and cooperate to form an omnidirectional closed structure, the contact points between the female and male signal terminals are completely enclosed within the shielding shell structure, creating an excellent shielding effect. This achieves an effect similar to quasi-coaxial transmission, enabling most of the energy to be transmitted closed-loop, significantly reducing energy loss, mitigating signal crosstalk between adjacent mated female and male connecting components, and obtaining high-quality signal transmission.

[0012] In one embodiment, the female end shielding shell includes a first shielding half shell and a second shielding half shell. Both the first shielding half shell and the second shielding half shell are provided with a first positioning hole. The female end mounting member is provided with a first positioning protrusion on both sides opposite to the first shielding half shell and the second shielding half shell.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figure 1 As shown, an electrical connector 100 is illustrated in one embodiment of this application. It is used in large communication equipment, ultra-high performance servers, supercomputers, industrial computers, or high-end storage devices to achieve high-speed data transmission and has excellent signal transmission quality.

[0038] Typically, the electrical connector 100 comprises two connector units used in pairs, that is, the electrical connector 100 includes a female connector 10 and a male connector 20. By mating the female connector 10 and the male connector 20 together, communication signals can be transmitted between two different communication devices.

[0039] Please continue reading. Figures 1 to 5 ,as well as Figures 8 to 11 The female connector 10 includes at least two female connection components 11 arranged side by side. Each female connection component 11 includes a female shielding shell 111 and a female signal terminal 112 disposed on the female shielding shell 111. The male connector 20 includes at least two male connection components 21 arranged side by side. The male connection components 21 are arranged one-to-one with the female connection components 11. Each male connection component 21 includes a male shielding shell 211 and a male signal terminal 212 disposed on the male shielding shell 211. The male shielding shell 211 and the female shielding shell 111 are nested and connected to form an omnidirectional closed structure. The male signal terminal 212 is in electrical contact with the female signal terminal 112 and is enclosed within the omnidirectional closed structure.

[0040] Please continue reading. Figure 2 and Figure 9 Furthermore, in this embodiment, the female connector 10 also includes a female connector base 12, which has at least two first slots 121. The number of first slots 121 is adapted to the number of female connector components 11, and the female connector components 11 are inserted into the first slots 121 one by one. The male connector 20 also includes a male connector base 22, which has at least two second slots 221. The number of second slots 221 is adapted to the number of male connector components 21, and the male connector components 21 are inserted into the second slots 221 one by one.

[0041] The female connector 11 can be securely installed by inserting it into the first slot 121. Similarly, the male connector 21 can also be securely installed by inserting it into the second slot 221. Moreover, this plug-in installation method has a simple structure, low design and manufacturing difficulty, and is convenient for assembly and disassembly.

[0042] Furthermore, to prevent the female end connection component 11 from falling out of the first slot 121 and the male end connection component 21 from falling out of the second slot 221, the female end shielding shell 111 and the first slot 121 are designed to be contoured and size-matched, and the male end shielding shell 211 and the second slot 221 are also designed to be contoured and size-matched. In this way, the tight fit between the outer wall of the shell and the wall of the slot can achieve a reliable installation effect.

[0043] Alternatively, a locking body or locking position can be provided on the groove wall of the first slot 121 and the second slot 221, and a locking position or locking body can be provided on the outer wall of the female shield shell 111 and the male shield shell 211 respectively. The female connection component 11 and the male connection component 21 can be reliably installed by the locking body and the locking position being connected by a snap-fit.

[0044] The female connector 12 and male connector 22 are preferably integrally injection molded from plastic, both comprising a carrier plate and a housing mounted on the carrier plate. The side of the housing away from the carrier plate is open and recessed inward to form a mounting cavity, within which a first slot 121 and a second slot 221 are formed respectively. To achieve high-speed signal transmission, the female connector 12 and male connector 22 are respectively provided with an array of multiple first slots 121 and multiple second slots 221. Correspondingly, the female connector assembly 11 and male connector assembly 21 are also provided with multiple slots, which are inserted into the corresponding first slots 121 and corresponding second slots.

[0045] Please continue reading. Figure 1 , Figure 2 , Figure 8 and Figure 9 During installation, the female connector 12 and the male connector 22 are aligned and inserted into each other for fixation. To ensure the accuracy of the insertion and the strength of the connection after insertion, the outer wall of the female connector 12's housing is provided with multiple positioning protrusions 122. Correspondingly, the male connector 22's housing is provided with multiple positioning notches 222 that correspond to the positions of the positioning protrusions 122 and are matched in number. The positioning protrusions 122 can be inserted into the positioning notches 222.

[0046] Furthermore, the carrier plates of the female connector 12 and the male connector 22 are respectively provided with arrays of through holes. The female signal terminal 112 is provided with female signal pins, which protrude from the corresponding through holes. The male signal terminal 212 is provided with male signal pins, which protrude from the corresponding through holes. This facilitates cable connection between the electrical connector 100 and other external communication devices.

[0047] In this embodiment, both the female shielding shell 111 and the male shielding shell 211 are formed as rectangular cylinders. The external dimensions of the male shielding shell 211 are slightly smaller than the internal dimensions of the female shielding shell 111, so that during the mating connection, a portion of the male shielding shell 211 can be inserted and nested into the female shielding shell 111 to form an omnidirectional closed structure. It should be noted that the so-called omnidirectional shielding structure means that after the female shielding shell 111 and the male shielding shell 211 are nested together, there is no fitting gap, and the transmitted signal cannot escape from the inside of the shell to the outside, thus preventing interference with adjacent transmitted signals.

[0048] Please continue reading. Figure 13 In summary, implementing the technical solution of this embodiment will have the following beneficial effects: When the electrical connector 100 of the above solution is used, the female connector 10 and the male connector 20 are connected by mating. The female connector 10 includes at least two female connection components 11, which are correspondingly connected to at least two male connection components 21 of the male connector 20, ensuring a good electrical connection. Specifically, the male shielding shell 211 of each male connection component 21 is nested with the corresponding female shielding shell 111 of the female connection component 11. Simultaneously, the female signal terminal 112 installed in the female shielding shell 111 and the male signal terminal 212 installed in the male shielding shell 211 have good contact, achieving high-speed signal transmission. Because the male shield 211 and the female shield 111 are nested together and form an omnidirectional closed structure, the contact area between the female signal terminal 112 and the male signal terminal 212 is inside the completely enclosed shield structure, resulting in excellent shielding. This achieves an effect similar to quasi-coaxial transmission, enabling most of the energy to be transmitted in a closed loop, significantly reducing energy loss, mitigating signal crosstalk between adjacent mating female connection components 11 and male connection components 21, and obtaining high-quality signal transmission.

[0049] Please continue reading. Figure 4 and Figure 11In some embodiments, each female connection component 11 includes two female signal terminals 112, which are used in pairs. Similarly, each work order connection component also includes two male signal terminals 212, which are used in pairs. Therefore, after the female connection component 11 is plugged into the corresponding male connection component 21, the female signal terminals 112 and male signal terminals 212 make good contact in a one-to-one correspondence, thereby helping to improve the reliability of signal transmission. Preferably, in this embodiment, the female signal terminals 112 are configured as flexible signal terminals, and the male signal terminals 212 are configured as rigid signal terminals. The flexible female signal terminals 112 can ensure effective and reliable contact with the rigid male signal terminals 212, which have a strong contact capability, thus always ensuring reliable signal transmission.

[0050] Please continue reading. Figure 10 , Figure 13 and Figure 14 Furthermore, the male end shielding shell 211 is provided with at least two elastic contacts 211a, which are distributed on opposite and / or adjacent sides of the male end shielding shell 211. Each elastic contact 211a elastically abuts against the corresponding inner wall of the female end shielding shell 111. For example, in this embodiment, four elastic contacts 211a are provided, with two elastic contacts 211a arranged on opposite sides in the length direction of the male end shielding shell 211, and the remaining two elastic contacts 211a arranged side by side on the same side in the width direction of the male end shielding shell 211, that is, the four elastic contacts 211a are arranged on three sides. When the male connector 21 is plugged into the female connector 11, the four elastic contacts 211a are elastically pressed against the three inner walls of the female shielding shell 111. The elastic pressure of the contacts 211a further ensures a firm connection between the male and female shielding shells 211 and 111, preventing loosening and ensuring normal signal transmission. Furthermore, the elastic contacts 211a in three directions form a semi-enclosed shielding contact with the female shielding shell 111. This ensures that the signal within the male-female mating area is aggregated by the surrounding shielding shell, achieving high-quality signal transmission and maximizing the shielding and isolation of adjacent transmission signals.

[0051] Of course, it is necessary to note that in other embodiments, the number and arrangement of the elastic contacts 211a can also adopt other schemes, which can be selected according to actual needs, and will not be elaborated here.

[0052] Please continue reading. Figure 4 and Figure 5Furthermore, based on any of the above embodiments, the female end connection assembly 11 further includes a female end mounting component 113, on which the female end signal terminal 112 is disposed, and the female end mounting component 113 is disposed within the female end shielding shell 111. The female end mounting component 113 is made of plastic, resulting in low design and manufacturing costs, and possessing a certain structural strength. The female end mounting component 113 has two vertically penetrating through holes, into which the female end signal terminal 112 is directly inserted, simplifying the installation method and ensuring a stable installation.

[0053] Please continue reading. Figure 4 , Figure 6 and Figure 7 Furthermore, the female end shielding shell 111 includes a first shielding half shell 111a and a second shielding half shell 111b. Both the first shielding half shell 111a and the second shielding half shell 111b are provided with a first positioning hole 111c. The female end mounting member 113 is provided with a first positioning protrusion 113a on both sides opposite to the first shielding half shell 111a and the second shielding half shell 111b, respectively. The first positioning protrusion 113a is inserted into the first positioning hole 111c.

[0054] Both the first shielding half-shell 111a and the second shielding half-shell 111b are U-shaped metal shells, and are fixed together by laser spot welding or other methods with equivalent technical effects. Therefore, the connection structure between the first shielding half-shell 111a and the second shielding half-shell 111b has high strength and stability, and excellent shielding effect. By using the first positioning hole 111c and the first positioning protrusion 113a for insertion and fixation, the female end mounting part 113 can be more securely installed and fixed inside the female end shielding shell 111, thereby ensuring the reliable installation of the female end signal terminal 112.

[0055] Please continue reading. Figure 11 and Figure 12 Furthermore, in some embodiments, the male terminal connection assembly 21 further includes a male terminal mounting component 213, on which the male terminal signal terminal 212 is disposed, and the male terminal mounting component 213 is disposed within the male terminal shielding shell 211. The male terminal mounting component 213 is made of plastic, resulting in low design and manufacturing costs, and possessing a certain structural strength. The male terminal mounting component 213 has two vertically penetrating through holes, into which the male terminal signal terminal 212 is directly inserted, simplifying the installation method and ensuring a stable installation.

[0056] Furthermore, the male end shielding shell 211 includes a third shielding half shell 211b and a fourth shielding half shell 211c. Both the third shielding half shell 211b and the fourth shielding half shell 211c are provided with a second positioning hole 211d. The male end mounting member 213 is provided with a second positioning protrusion 213a on both sides opposite to the third shielding half shell 211b and the fourth shielding half shell 211c, and the second positioning protrusion 213a is inserted into the second positioning hole 211d.

[0057] Both the third shielding half-shell 211b and the fourth shielding half-shell 211c are U-shaped metal shells, and are fixed together by laser spot welding or other methods with equivalent technical effects, thus possessing excellent structural strength and stability, as well as excellent shielding effect. Furthermore, by inserting and fixing the second positioning hole 211d and the second positioning protrusion 213a, the male end mounting part 213 can be more securely installed inside the male end shielding shell 211, thereby ensuring reliable installation of the male end signal terminal 212. During the mating connection, the male end signal terminal 212 will not move due to the frictional resistance of the female end signal terminal 112, thus affecting the connection reliability.

[0058] Furthermore, the male mounting component 213 has a perforated groove 213b located within the male-female mating area. This perforated groove 213b is formed within the contact area between the female signal terminal 112 and the male signal terminal 212, forming a male-female mating area with low impedance and capacitive properties. By providing the perforated groove 213b, the dielectric filler in this area can be effectively reduced, thereby achieving impedance control.
