[0002] With the advancement of technology, the data processing speed of modern network servers and supercomputers is getting faster and faster. Specialized processing chips (ASICs) use serial differential signal links to transmit ultra-high-speed data, which can reach up to hundreds of Gbps. In printed circuit boards (PCBs) where systems are complex and components are densely packed, it is becoming increasingly difficult to find wiring space that meets the requirements of high-speed differential data transmission. Therefore, it is necessary to transmit the high-speed differential signals of the specialized processing chips directly to the required equipment through precision cable connectors. The performance of the cable connector has a significant impact on the quality of signal transmission.

[0003] The cable connectors in the related art usually have too long connection length, which is disadvantageous for continuous signal transmission and complete transmission of signal waveforms. Here, the connection length refers to the length from the position where the outer shield layer of the micro-coaxial line of the plug is open to the position where the signal line is connected to the PCB board (i.e., circuit board).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present application will be described in detail with reference to the accompanying drawings, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are illustrative and are for the purpose of explaining the present application, and should not be construed as limitations on the present application.

[0032] This embodiment provides a cable connector for electrical signal connection between a cable 5 and a circuit board, the cable 5 may be a micro-coaxial cable or a shielded twisted pair cable, and high-speed differential signals can usually be transmitted using a two-core micro-coaxial cable. Each cable 5 may be a single-core, two-core or multi-core cable, and the present embodiment will be described taking two-core cable as an example.

[0033] 1 to 3, the cable connector provided in this embodiment includes a socket 10 and a plug 20, the socket 10 has an opening 11 and a connection portion 12 for connecting a circuit board 1, and in conjunction with FIG. 8 to FIG. 10, the plug 20 includes a fixing member 21 and an elastic connecting member 22, the elastic connecting member 22 includes a fixing portion 221 and a first elastic contact portion 222 connected to the fixing portion 221, the fixing portion 221 is fixedly connected to the fixing member 21 and configured to connect the inner conductor 2 of the cable 5, the fixing member 21 is connected to the socket 10, and the first elastic contact portion 222 passes through the opening 11 and elastically contacts the signal connection contact 3 on the circuit board 1 to form an electrical connection. From the viewpoint of signal transmission, the cable connector of this embodiment has only two relays: a connection from the inner conductor 2 of the cable 5 to the elastic connecting member 2, and a pressing from the first elastic contact portion 222 of the elastic connecting member 22 to the signal connection contact 3 of the circuit board 1. Other connectors in the related art usually have three or more relays, so the number of relays in this embodiment is reduced by at least one, which is advantageous for reducing the connection length of the cable connector and reducing discontinuity in signal transmission. Furthermore, the cable connector of this embodiment is designed to shorten the connection length as much as possible, and by adopting the solution of this embodiment, a connection length of 4 mm or less can be achieved. Reducing the connection length is advantageous for impedance matching between the cable connector and the twin-core coaxial line, and improves signal integrity.

[0034] In a specific embodiment, referring to FIG. 2, the socket 10 includes a first housing 13, and the opening 11 and the connection portion 12 are both formed in the first housing 13. The opening 11 is an insertion port for the plug 20, and at least a part of the structure of the plug 20 enters the first housing 13 through the opening 11 to form a mating connection with the first housing 13, so that the first elastic contact portion 222 can elastically contact the signal connection contact 3 on the circuit board 1. The elastic contact here refers to the first elastic contact portion 222 being pressed against the signal connection contact 3. The elastic deformation of the first elastic contact portion 222 ensures that the first elastic contact portion 222 is always pressed against the signal connection contact 3 when the plug 20 and the socket 10 are connected. Specifically, the fixing member 21 is connected to the first housing 13, and the first elastic contact portion 222 can pass through the opening 11 and elastically contact the signal connection contact 3 on the circuit board 1 to form an electrical connection. The first housing 13 is connected to the circuit board 1, while limiting the insertion position of the plug 20, and provides a good interface between the elastic connection member 22 in the plug 20 and the signal connection contacts 3 of the circuit board 1. Good connection with Ensure that:

[0035] Further, referring to FIG. 9 and FIG. 10, the fixing member 21 includes a second housing 211 and an insulator 212, one end of the insulator 212 is fixed in the second housing 211, an insulating groove 2121 is opened in the insulator 212, and the elastic connecting member 22 penetrates the insulating groove 2121. One role of the insulator 212 is to ensure insulation between the elastic connecting member 22 and other conductive structures, and mainly to avoid short circuits between multiple elastic connecting members 22. The insulator 212 may be designed based on the internal shape of the second housing 211, and specifically, may be a matrix made of an insulating material (e.g., liquid crystal polymer, LCP). The insulator 212 may support the elastic connecting member 22 and also play a role in fixing the position of the elastic connecting member 22. The insulator 212 may be an integral body or may be composed of multiple divided bodies, but in the drawings of this embodiment, the insulator 212 is composed of multiple divided bodies.

[0036] Furthermore, the second housing 211 and / or the insulator 212 can be connected to the first housing 13 and the first elastic contact portion 222 can pass through the opening 11 to contact the signal connection contact 3 on the circuit board 1 to form an electrical connection. That is, the second housing 211 may be connected to the first housing 13 via the second housing 211, or the first housing 13 may be connected to the insulator 212, or both the second housing 211 and the insulator 212 may be connected to the first housing 13.

[0037] In this embodiment, the insulator 212 is press-fitted into the second housing 211, such that the insulator 212 is fixed to the second housing 211 by a press-fit method, with a portion of the structure of the insulator 212 located within the second housing 211 and the remaining structure protruding from the second housing 211 and located outside the second housing 211.

[0038] Furthermore, the insulator 212 and / or the second housing 211 are formed with a first connection portion 2122, i.e., the first connection portion 2122 may be formed in the insulator 212, may be formed in the second housing 211, or may be provided in both the insulator 212 and the second housing 211. The first housing 13 is provided with a second connection portion 131 for mating and connecting with the first connection portion 2122. A plurality of the first connection portions 2122 and the second connection portions 131 are provided, and correspond one-to-one.

[0039] Specifically, the first connection portion 2122 is a protrusion structure formed on the insulator 212 and / or the second housing 211, and in this embodiment, the protrusion structure is a wedge-shaped block, and the second connection portion 131 is a locking groove opened in the first housing 13.

[0040] Combining FIG. 1 and FIG. 6, in order to further improve the connection stability between the plug 20 and the socket 10, the first housing 13 may be provided with a fixing portion 132 for fixing the second housing 211 when the fixing member 21 is connected to the first housing 13. Specifically, the fixing portion 132 is an elastic hook formed at the position of the opening 11 of the first housing 13, and can be pressed against the second housing 211 when the fixing member 21 is connected to the first housing 13. When the plug 20 is inserted into the socket 10, the elastic hook elastically deforms to allow the plug 20 to pass, and when the plug 20 is fully inserted, it is reset to fix the second housing 211. In addition, by providing the fixing portion 132, good conductivity between the second housing 211 and the first housing 13 can be ensured.

[0041] In some specific embodiments, the first housing 13 and the second housing 211 are both shielded housings with signal shielding function, and both may be made of stainless steel metal pieces with a certain thickness.

[0042] In some specific embodiments, the number of elastic connecting members 22 is multiple, and they are divided into multiple sets fixedly connected to the fixing member 21, and each set includes at least one elastic connecting member 22; the number of insulating grooves 2121 is multiple, and each insulating groove 2121 is provided with one elastic connecting member 22. Referring to Figures 3, 7 to 10, the elastic connecting members 22 are divided into four sets, and each set includes two elastic connecting members 22; 9 to 12, the plug 20 further includes a shield plate 23, which is fixedly connected to the fixed member 21 to isolate each pair of elastic connecting members 22. The shield plate 23 may be fixed together with the second housing 211, or the two may be integrally molded by injection molding, which can improve the shielding effect and ensure the stability of signal transmission.

[0043] Specifically, the shield plate 23 is a metal plate that is bent to form a plurality of isolated spaces 231, and a set of elastic connecting members is provided within each isolated space 231. The metal plate may be a single piece, or may be formed by joining a plurality of pieces together. The shape of the shield plate 23 may be wavy as shown in Figs. 11 and 12.

[0044] Moreover, the shield plate 23 has a second elastic contact portion 232 for elastically connecting with the ground connection contact 4 on the circuit board 1, so that the shield plate 23 also has a ground function.

[0045] In order to ensure insulation between the elastic connecting member 22 and the shield plate 23, referring to Figures 8 and 10, a part of the structure of the insulator 212 may be set to be located between the shield plate 23 and the elastic connecting member 22.

[0046] In addition, all the elastic connecting members 22 in each set are bent in the same direction, and the bending directions of the elastic connecting members 22 in adjacent sets are opposite to each other, so that the directions of the horizontal forces applied to the circuit board 1 by the elastic connecting members 22 are opposite to each other, thereby canceling out the horizontal forces, improving the stability of the connection, and facilitating the isolation between the elastic connecting members 22 in adjacent sets.

[0047] 4 and 13 to 15, the first elastic contact portion 222 has an arc structure, which facilitates elastic contact between the first elastic contact portion 222 and the circuit board 1. Furthermore, the shape of the elastic connecting member 22 may be S-shaped (as shown in FIG. 15), C-shaped, or L-shaped (as shown in FIG. 14). The first elastic contact portion 222 may be C-shaped as shown in FIG. 13. These shapes indicate an arc and an obtuse angle connection in the signal path, and do not bend at an acute angle or a right angle, which helps to reduce signal reflection. Note that the S-shape, C-shape, or L-shape here is a rough structural outline of the elastic connecting member 22, and the actual elastic connecting member 22 may have reasonable structural differences from the corresponding characters. Therefore, the present application does not limit the shape of the elastic connecting member 22 to be completely the same as the shape of the characters.

[0048] In order to shorten the connection length, the design requirement of the mechanical structure of the elastic connection member 22 is to make the length as small as possible so as to have sufficient contact pressure and sufficient stroke range to ensure the reliability and stability of the connection. The design requirement of the circuit of the elastic connection member 22 is to ensure that the characteristic impedance of the inner conductor 2 and the elastic connection member 22 in the cable connector are mapped to the characteristic impedance of the cable.

[0049] 1 and 5 to 6, when fixing member 21 is connected to socket 10, the entire plug 20 is located inside first housing 13. As a result, first housing 13 and second housing 211 enclose and shield elastic connecting member 22 in all directions, ensuring that high-speed signals are not radiated to the outside when passing through, and making it possible to avoid electromagnetic leakage and interference.

[0050] The cable connector of this embodiment also strengthens the design of electromagnetic shielding. The first housing 13 and the second housing 211 in the cable connector realize external shielding. Inside the cable connector, the number of sets of elastic connecting members 22 in the plug 20 is the same as the number of data channels of the cable, and in order to prevent signal crosstalk between channels, a shield plate 23 is provided on both the left and right sides and the rear of each set of elastic connecting members 22, so that different sets of elastic connecting members 22 are isolated from each other. As shown in FIG. 16, in conjunction with FIG. 11 and FIG. 12, in order to simplify the design of the shield plate 23, only one corrugated metal plate can be used to isolate four sets of elastic connecting members 22, and there is a second elastic contact portion 232 on the periphery of each set of elastic connecting members 22 on average. The circuit board is provided with a signal connecting contact 3 and a ground connecting contact 4 correspondingly. FIG. 16 shows the position of the shield plate 23 in a schematic manner. Signal connection contacts 3 and ground connection contacts 4, also known as gold fingers, are pads or contacts that are gold plated onto a surface on a circuit board and are distinguished here by their function.

[0051] The signal connection contacts 3 of each set of elastic connection members 22 and the ground connection contacts 4 of the second elastic contact portion 232 (also called the ground connection portion) are distributed in a shape similar to that of the elastic connection members 22. By setting the shape of the shield plate 23 as described above and increasing the number of ground portions on the shield plate 23, the shielding between each data channel can be further strengthened.

[0052] In order to reduce the inductive coupling between the two sets of elastic connecting members 22, the spatial arrangement of the two adjacent sets of elastic connecting members can be further adjusted. Referring to Fig. 17-18, each set of elastic connecting members includes two of the elastic connecting members 22 spaced apart in the spacing direction, and the angle range of the spacing direction of any two adjacent sets of elastic connecting members is 85°-95°. The optimum value is 90°, that is, the spacing directions of any two adjacent sets of elastic connecting members are perpendicular or nearly perpendicular to each other.

[0053] As shown in FIG. 18, the cable connector is provided with a total of four sets of elastic connecting members, each set includes two elastic connecting members 22, and the spacing directions of the four sets of elastic connecting members are represented as a1, a2, a3, and a4, where the spacing direction a1 is perpendicular to the spacing direction a2 and the spacing direction a4, and the spacing direction a3 is perpendicular to the spacing direction a2 and the spacing direction a4. In conjunction with FIG. 19, the shape of the shield plate 23 is correspondingly a cross partition plate shape, and four isolated spaces 231 are formed. In other embodiments, the cable connector may be provided with more sets of elastic connecting members, and the shield plate 23 also forms more isolated spaces 231 accordingly. Those skilled in the art can make corresponding extensions based on the inventive idea of ​​the present application.

[0054] Based on the description of the cable connector above, this embodiment further provides an electronic device including a circuit board 1, a cable 5, and the cable connector of this embodiment, in which the inner conductor 2 of the cable 5 is welded to the fixing portion 221, the first housing 13 of the cable connector is fixed to the circuit board 1 via the connection portion 12, and the plug 20 of the cable connector is inserted into the socket 10.

[0055] In some embodiments, the fixing member 21 is provided so as to be able to make a sealing connection with the shielding layer of the cable 5. Specifically, the shielding layer on the outer surface of the cable 5 and the second housing 211 are sealed together to integrate them without any gaps and ensure the maximum shielding effect. If it is not possible to leave no gaps between them in some processes, maximum sealing can be performed based on the current process, and if there are other design requirements for the shielding layer on the outer surface of the cable 5, the shielding layer on the outer surface of the cable 5 and the second housing 211 may be at least partially sealed.
