Description

Technical Field

[0001] The utility model relates to a plug assembly applied to an electric connector, belonging to the technical field of electric signal transmission equipment. Background Art

[0002] With the continuous increase in signal transmission rate and power density, the use of PCB circuits as carriers for signal transmission not only faces signal integrity problems such as attenuation, crosstalk, and distortion during high-speed signal transmission, but also faces practical problems such as insufficient space due to the electrical characteristics of high-speed signals themselves. Using electrical connectors to replace traditional PCB circuit signal transmission methods can largely solve the above problems. However, electrical connectors are small in size and complex in structure, and some key structures may cause potential risks. If they are not carefully designed and installed, the performance of the electrical connectors will not only fail to meet design expectations, but may also deteriorate sharply.

[0003] Among them, in order to solve the problem that gaps appear in the shielding structure of the electrical connector, causing current of a specific frequency to flow through the gaps and cause interference, the existing technology includes using an integrated die-casting process or CNC processing technology to form an integrated shielding junction, or welding to eliminate the gap after multiple single spacers are spliced ​​into a whole. However, in reality, it is difficult to complete the processing of complex heterogeneous structures with an integrated die-casting process or CNC processing technology. The processing accuracy is low, and the thickness of the shielding structure formed is relatively large, which is difficult to apply inside a complex and precise electrical connector. The method of welding the gap between two single spacers not only requires the use of a clamp, but also introduces additional process costs. As the spacers are required to become thinner, the welding difficulty and production cost are further increased. With the continuous complexity and precision of electrical connectors, the existing electrical connector shielding structure and its installation method can no longer meet the demand. Utility Model Content

[0004] The utility model provides a plug assembly for an electrical connector, aiming to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a plug assembly for an electrical connector, which at least reduces the probability of mutual interference inside the electrical connector by adopting a new spacer installation method, and at the same time alleviates the contradiction between the complexity and precision of the electrical connector and the insufficient internal space requirement.

[0005] The technical solution of the utility model relates to a plug assembly applied to an electrical connector, comprising:

[0006] A plug connecting plate and at least two plug partitions, and a line card plate allowing a transmission cable to pass through; the plug partition is provided with a snap-in protrusion, and the line card plate and / or the plug connecting plate are provided with at least one recess allowing the snap-in protrusion to be inserted, so that the line card plate and the plug connecting plate are respectively connected to the plug partition, thereby forming an independent space that plays a shielding role.

[0007] Furthermore, the recessed portion includes an offset hole, and at least one end of the offset hole is biased toward one side relative to the clamping protrusion.

[0008] Furthermore, among the at least two offset holes arranged on the plug connecting plate, a first end of at least one of the offset holes is offset toward a first direction, and a first end of at least one other of the offset holes is offset toward a second direction.

[0009] Furthermore, the first end of one of the offset holes is offset toward a first direction, and the first end of the offset hole adjacent to the offset hole is offset toward a second direction.

[0010] Furthermore, the offset hole has an S-shaped structure.

[0011] Furthermore, the clamping protrusion is provided with two clamping protrusions, and the two clamping protrusions are arranged at opposite ends of the clamping protrusion.

[0012] Furthermore, it also includes a line card board for accessing the transmission cable, and the line card board is connected to the plug partition.

[0013] Furthermore, more than two groups of spacer assemblies consisting of the line card board, the plug connection board and at least two plug spacers are provided.

[0014] Further, the line card board is connected to at least one conductor and / or shielding layer in the transmission cable that provides signal shielding.

[0015] Furthermore, the line card board, the plug connection board and the plug partition board are all made of metal materials.

[0016] The beneficial effects of the utility model are as follows.

[0017] By adopting a new spacer installation method, it is helpful to reduce the probability of mutual interference inside the electrical connector, and at the same time alleviate the contradiction between the complexity and precision of the electrical connector and the insufficient internal space demand. For the space between the plug partition and the plug connection plate, and between the plug partition and the line card plate, the offset hole and tight fit assembly method are adopted, which can effectively eliminate the assembly gap at the board joint and effectively prevent the induced current from flowing through the gap and causing signal interference. This assembly method not only eliminates the production step of the welding gap, but also simplifies the shielding structure by adopting a single partition splicing method, avoiding the complex special-shaped structure processed by the integrated die-casting process and CNC process, thereby reducing the processing difficulty and facilitating the assembly accuracy. In addition, this assembly method can further reduce the thickness of a single spacer and alleviate the problem of insufficient internal space of the electrical connector.

[0038] See also Figures 1 to 9 In some embodiments, the plug assembly applied to the electrical connector according to the utility model includes a plug connecting plate 120 and at least two plug partitions 130, as well as a line card board 110 that allows the transmission cable 300 to pass through. The plug partition 130 is provided with a snap-in protrusion 150, and the line card board 110 and / or the plug connecting plate 120 are provided with at least one recess allowing the snap-in protrusion 150 to be inserted, so that the line card board 110 and the plug connecting plate 120 are respectively connected to the plug partition 130, thereby forming an independent space 160 that serves a shielding function.

[0039] See also Figures 1 to 9In some embodiments, the plug assembly 100 connected to at least one transmission cable 300 includes a line card board 110, a plug connection board 120, and at least two plug partitions 130. One or more snap-in protrusions 150 may be provided at the end of each plug partition 130, and one or both of the line card board 110 and the plug connection board 120 may be provided with one or more recesses to cooperate with the snap-in protrusions 150, so that each recess can be inserted into the snap-in protrusion 150. The recess may be a through hole, a blind hole, a groove, a cutout, etc. of various shapes, as long as at least a portion of the snap-in protrusion 150 is allowed to be directly inserted.

[0040] Reference Figure 4 and Figure 5 Preferably, the recessed portion may be an offset hole 140. Each snap-fitting protrusion 150 may be inserted into each offset hole 140, so that the line card board 110 and the plug connection board 120 are respectively connected to the plug partition board 130, thereby forming an independent space 160 for shielding. Preferably, at least one end of the offset hole 140 is biased to one side relative to the snap-fitting protrusion 150. Further, the width of the offset hole 140 is substantially the same as the thickness of the snap-fitting protrusion 150 (which may also be equal to the thickness of the plug partition board 130), and at least one end of the offset hole 140 is biased to one side relative to the snap-fitting protrusion 150, so that part of the inner wall of the offset hole 140 abuts against the side of the snap-fitting protrusion 150, thereby utilizing the "interference fit" between the offset hole 140 and the snap-fitting protrusion 150 to achieve splicing feasibility while facilitating high splicing reliability, and facilitating elimination of gaps at the splicing location, reducing the probability of mutual interference within the electrical connector.

[0041] See also Figure 1 and Figure 2 In some embodiments, the electrical connector includes a plug assembly 100 connected to a plurality of transmission cables 300 and a socket assembly 200 connected to a circuit board 400. When the plug assembly 100 is inserted into the socket assembly 200, the transmission cables 300 are indirectly connected to the circuit board 400 through the conductive member 350. The plug assembly 100 includes a plug housing (not shown in the drawings), a line card board 110, a plug connecting board 120, and a plurality of plug partitions 130. The line card board 110, the plug connecting board 120, and the plug partitions 130 are all disposed in the plug housing. The plurality of plug partitions 130 may be parallel to each other and perpendicular to the plug connecting board 120, and one side of the plurality of plug partitions 130 is inserted into the plug connecting board 120. The plug connecting board 120 is disposed on the front side or the rear side of the plug partition 130. Referring to Figure 2, a plurality of plug partitions 130 are inserted into the line card board 110 on the side away from the circuit board 400, and the plug connection board 120 is perpendicular to the line card board 110, the line card board 110 is perpendicular to the plug partition 130, and the line card board 110 is arranged on the upper side of the plug partition 130. The line card board 110, the plug connection board 120 and the plug partition 130 are combined to form an independent space 160 for shielding, and each group of conductive members 350 is respectively arranged in an independent space 160, thereby forming an enclosure and separation of the conductive members 350, and playing a good role in shielding interference.

[0042] Based on such a plug-in relationship, a compact cable arrangement can be achieved. Figure 1 and Figure 8 The number of the spacer assembly consisting of the line card board 110, the plug connection board 120 and at least two plug spacers 130 can be multiple, wherein multiple transmission cables 300 are arranged in parallel in each spacer assembly. Figure 8 The electrical connector may be provided with two sets of spacer assemblies, which are symmetrically arranged facing each other to form two sets of cable assemblies. The transmission cables 300 of each set of cable assemblies are arranged side by side. This layout significantly saves space.

[0043] See also Figures 3 to 7 In some embodiments, the line card board 110 and the plug connection board 120 are both provided with an offset hole 140, and the plug partition 130 is provided with a snap-in protrusion 150. The snap-in protrusion 150 is inserted into the offset hole 140, so that the plug connection board 120 and the line card board 110 are respectively connected to the plug partition 130. Further, the line card board 110, the plug connection board 120 and the plug partition 130 can all be made of metal materials, and further, the metal materials used are conductive. The snap-in protrusion 150 can be an arc, a polygon or other shapes that are convenient for insertion into the offset hole 140. Preferably, referring to Figure 7 The snap-fitting protrusion 150 is a square plate-shaped structure, the front and rear sides of the snap-fitting protrusion 150 are planes, the offset hole 140 is an elongated groove, the thickness of the snap-fitting protrusion 150 is substantially the same as the width of the offset hole 140, and the front and rear side walls of the offset hole 140 are not parallel to the front and rear sides of the snap-fitting protrusion 150, so that when the snap-fitting protrusion 150 is inserted into the offset hole 140, the snap-fitting protrusion 150 undergoes a slight elastic deformation, so that the side of the snap-fitting protrusion 150 abuts against part of the inner wall of the offset hole 140, thereby utilizing the advantages of interference fit, which is conducive to ensuring the feasibility of splicing while achieving reliable connection between the spacers and effectively eliminating the splicing gap. It should be understood that the thickness of the snap-fitting protrusion 150 can be less than 1 mm or even less than 0.5 mm, and the plug partition 130 is made of flexible metal material, so multiple snap-fitting protrusions 150 of multiple plug partitions 130 can also be inserted into the plug connection board 120.

[0044] Further, in some embodiments, relative to the plane where the front and rear sides of the clamping protrusion 150 are located, one end of the offset hole 140 is offset to the front side or the rear side (see Figure 5 ), for example, the upper end of the offset hole 140 is offset toward the front side or the rear side, or the lower end of the offset hole 140 is offset toward the front side or the rear side, or the upper end of the offset hole 140 is offset toward the front side and the lower end of the offset hole 140 is offset toward the rear side, or the upper end of the offset hole 140 is offset toward the rear side and the lower end of the offset hole 140 is offset toward the front side, so that the inner wall portion of the offset hole 140 abuts against the side of the snap-in protrusion 150.

[0045] Furthermore, on the line card board 110 provided with the offset hole 140 and on the plug connection board 120 provided with the offset hole 140, at least two offset holes 140 on the same spacer have different offset directions, that is, the first end 141 of at least one offset hole 140 is offset in the first direction, and the first end 141 of at least one other offset hole 140 is offset in the second direction, thereby facilitating further improving the connection stability. This is described with an embodiment, for example, see Figure 4 , with the front end of the offset hole 140 as the first end 141, on the plug connection plate 120, the front end of at least one offset hole 140 is offset toward the front side, and at the same time, the front end of at least one offset hole 140 is offset toward the rear side, for example, see Figure 6 With the rear end of the offset hole 140 as the first end 141, on the line card board 110, the rear end of at least one offset hole 140 is offset toward the front side, and at the same time, the rear end of at least one offset hole 140 is offset toward the rear side.

[0046] Furthermore, in some embodiments, the offset directions of two adjacent offset holes 140 are different, see Figure 4 and Figure 5 , the plug connection board 120 is provided with multiple rows and columns of offset holes 140. In the offset holes 140 in the same column, the first ends 141 of two adjacent offset holes 140 are offset in the first direction and the second direction respectively. It can be understood that it can also be set that in the offset holes 140 in the same row, the first ends 141 of two adjacent offset holes 140 are offset in the first direction and the second direction respectively. For example, the A offset hole 140 is adjacent to the B offset hole 140 and is arranged in the same column. The first end 141 of the A offset hole 140 is offset in the first direction, and the first end 141 of the B offset hole 140 is offset in the second direction, wherein the first direction does not overlap with the second direction, thereby further improving the connection stability and preventing the connection partition or line card board 110 from offsetting to one side after being clamped. It should be understood that the first direction and the second direction can be interchangeable. In addition, in some embodiments, among the multiple offset holes 140 in each row or column, at least one offset hole 140 with a different orientation of the first end 141 is arranged.

[0047] Furthermore, in some embodiments, the front and rear side walls of the offset hole 140 can be curved surfaces that are not parallel to the front and rear side surfaces of the snap-in protrusion 150, so that the inner wall of the offset hole 140 abuts against the side portion of the snap-in protrusion 150, utilizing the advantages of interference fit, which is conducive to achieving snap-in feasibility while improving snap-in reliability and effectively eliminating snap-in gaps.

[0048] For the electrical connector of the embodiment of the utility model, the advantage of interference fit is used to realize the splicing connection of multiple single spacers. While ensuring the feasibility of the snap-in, it is not only beneficial to improve the stability of the connection, but also beneficial to reduce the probability of gaps appearing at the plug-in point, and at the same time replaces the traditional method of eliminating gaps by welding, thereby not only reducing the difficulty of installation and process costs, but also because a single spacer is used to replace the complex shielding structure formed in one piece, it solves the problem that the integrated die-casting process and CNC processing technology are difficult to realize the processing of complex heterogeneous structures. A single spacer is formed by stamping a mold, which is beneficial to improving the processing accuracy of the shielding structure, and further reducing the thickness of a single spacer used to form the shielding structure, alleviating the problem of insufficient internal space caused by the complexity and precision of the electrical connector.

[0049] Reference Figure 4 and Figure 6 In some embodiments, both the line card board 110 and the plug connection board 120 may be provided with an offset hole 140. The two opposite side walls of the offset hole 140 are provided with extensions 142, which extend toward the inside of the offset hole 140, and the two extensions 142 are respectively provided at opposite ends of the offset hole 140. Preferably, the offset hole 140 is S-shaped or "mirror S-shaped", so that the front and rear side walls of the offset hole 140 are not parallel to the corresponding front and rear side faces of the snap-in protrusion 150. When the snap-in protrusion 150 is inserted into the offset hole 140, stress is generated at the abutment between the side face and the side wall, so that the snap-in connection between the offset hole 140 and the snap-in protrusion 150 has the advantage of interference fit. The snap-in protrusion 150 can be snapped into the S-shaped offset hole 140 and improve the connection reliability, and is conducive to eliminating the gap at the connection between the line card board 110 and the plug partition 130, and eliminating the gap at the connection between the plug connecting board 120 and the plug partition 130, thereby achieving effective isolation and shielding between the conductive parts 350, solving the problem of difficulty in complete contact between the metal sheets, and preventing interference caused by current flowing through the gap.

[0050] See also Figure 5In some embodiments, the offset hole 140 is a strip-like structure, and two extensions 142 are respectively arranged on the front side wall and the rear side wall of the offset hole 140, and are respectively arranged on the left end and the right end of the offset hole 140. Both extensions 142 extend toward the inside of the offset hole 140, that is, one extension 142 extends forward, and the other extension 142 extends backward, thereby forming an S-shaped offset hole 140, so that the front and rear side walls of the offset hole 140 in contact with the clamping protrusion 150 are curved surfaces, and the side surfaces of the two side walls in contact with the clamping protrusion 150 and the offset hole 140 are flat surfaces, so that the clamping protrusion 150 is partially abutted when inserted into the offset hole 140, thereby utilizing the advantages of interference fit to achieve the feasibility of plugging the plug connection board 120 and the line card board 110 with the plug partition 130, which is conducive to ensuring the reliable connection between the two partitions and effectively eliminating the gap at the plugging point. It can be understood that the two extensions 142 in this embodiment can be symmetrical about the center of the offset hole 140.

[0051] In some embodiments, two adjacent offset holes 140 are symmetrically arranged. Figure 4 and Figure 5 In some embodiments, the plug connection plate 120 is provided with two groups of three rows and three columns of offset holes 140. In the same column of offset holes 140 of the plug connection plate 120, any offset hole 140 and the offset hole 140 in front of it are symmetrical about the midline of the two, and the above offset hole 140 and the offset hole 140 in the back of it are also symmetrical about the midline of the two, that is, the protruding directions of the extensions 142 at the same end of two adjacent S-shaped holes in the same column are just opposite, which is conducive to further improving the connection stability between the plug connection plate 120 and the plug partition plate 130. Further, see Figure 6 In some embodiments, the line card board 110 is provided with a row of offset holes 140, and two adjacent offset holes 140 are symmetrical about the midlines thereof, that is, the protruding directions of the extension portions 142 of two adjacent S-shaped holes in the same row are just opposite, thereby facilitating further improving the connection stability between the line card board 110 and the plug partition board 130.

[0052] In some embodiments, the clamping protrusion 150 is provided with a clamping protrusion 151, which is provided at the end of the clamping protrusion 150 to improve the clamping stability. Further, two clamping protrusions 151 are provided, and the two clamping protrusions 151 are provided at opposite ends of the clamping protrusion 150. Figure 6 and Figure 7The clamping protrusion 150 is a flat plate and is arranged vertically, matching the long strip structure of the offset hole 140. The left and right ends of the clamping protrusion 150 are both provided with a clamping protrusion 151, and the clamping protrusion 151 is arranged on the upper side of the clamping protrusion 150, so that the left and right ends of the clamping protrusion 150 abut against the left and right ends of the offset hole 140, and the advantages of the interference fit are used to further eliminate the gap at the connection and improve the stability of the connection. It can be understood that in this embodiment, the clamping protrusion 151 can be set only on the clamping protrusion 150 connected to the line card board 110, or only on the clamping protrusion 150 connected to the plug connection board 120.

[0053] In some embodiments, the line card board 110 is provided with a threading hole 111 for the transmission cable 300 to pass through. Figure 3 , Figures 6 to 8 The threading hole 111 is connected to the independent space 160 accommodating the conductive member 350, and the signal line 320 of the transmission cable 300 is connected to the conductive member 350 through the threading hole 111. Thus, by opening the line card board 110, a larger threading space is provided for the transmission cable 300, which is conducive to making it easier for the transmission cable 300 to pass through the line card board 110.

[0054] In some embodiments, the line card board 110 can be used as a ground conductor of the transmission cable 300. The line card board 110 and the transmission cable 300 are connected by a wire 340, so that the line card board 110 serves as a ground conductor of the transmission cable 300. Furthermore, the line card board 110 is made of a conductive metal material. Fig. 9 and Fig.10a In some embodiments, the transmission cable 300 is a high-frequency cable that supports high-speed differential signals. Two signal lines 320 are provided in the transmission cable 300 as a set of differential line pairs. At the same time, the original ground wire (which can be a wire 340) is picked out of the transmission cable 300, and the remaining shielding layer 310 can also be connected to the ground wire at the same time. At the same time, a wire 340 is provided to connect the line card board 110 and the shielding layer 310 of the transmission cable 300 respectively. The shielding layer 310 is wrapped in the outermost insulating layer 360 of the transmission cable 300, wherein an insulating medium 330 is provided between the signal line 320 and the shielding layer 310. In this embodiment, the contacts in the circuit board 400 are correspondingly arranged so that each differential pair is spaced apart from each GND segment (see Fig.10b The circuit board 400 is connected to one end of the two conductive members 350 as two contacts of the differential pair, and the other ends of the two conductive members 350 are connected to the two signal lines 320 in the transmission cable 300 .

[0055] It can be understood that, in some embodiments, each transmission cable 300 may be provided with two conductors 340. The two conductors 340 are respectively provided at the front side and the rear side of the transmission cable 300. Figure 2 , Fig. 9 and Fig.10a , two wires 340 led out of the transmission cable 300, which may be the same or different, are respectively connected to the plug partition 130 at the front side (or left side) and the rear side (or right side) of the transmission cable 300, and the plug partition 130 at the middle of the line card 110 is connected to the two wires 340. In some embodiments, the wires 340, the plug partition 130 and the line card 110 can also be fixedly connected together at the transition connection position on one side of the line card 110 and the plug partition 130.

[0056] It can be understood that the utility model improves the transition mode between the transmission cable 300 and the electrical connector. One end of the wire 340 is connected to the shielding layer 310 of the transmission cable 300 as the ground wire, and the other end of the wire 340 is connected to the line card board 110, so that the line card board 110 is connected as the ground wire of the transmission cable 300, and the signal line 320 in the transmission cable 300 is directly welded to the conductive member 350, and then connected to the circuit board 400 through the conductive member 350. Compared with the conventional TwinAx line in which the signal line 320 and the ground wire are directly welded on the surface of the signal terminal, the scheme in this embodiment shortens the size required for welding the transmission cable 300 with the electrical connector, which is conducive to improving the electrical performance of the electrical connector, improving the continuity of the ground current, and shortening the main interference occurrence area between the circuit board 400 and the end of the shielding layer 310 of the transmission cable 300. Further, the shielding layer 310 of the transmission cable 300 as the ground wire contacts the inner wall of the threading hole 111, which is conducive to further improving the continuity of the ground current.

[0057] In some embodiments, see Figure 6 and Figure 7, the line card plate 110 is provided with a connection recess 112, and the plug partition plate 130 is provided with a connection protrusion 131, which is inserted into the connection recess 112. Specifically, the connection protrusion 131 is a flat plate and is arranged vertically, and the left and right ends of the connection protrusion 131 are provided with a snap-on protrusion 151, and the snap-on protrusion 151 is arranged on the upper side of the connection protrusion 131. A plurality of connection recesses 112 are respectively arranged on the left and right walls of the threading hole 111, and the connection recesses 112 are connected to the threading hole 111. The connection protrusion 131 passes through the threading hole 111, and the left and right sides of the connection protrusion 131 are respectively snapped into two connection recesses 112.
