The bottoms of the first reed assembly 101 and the second reed assembly 102 are each provided with two reeds 109 (not shown in fig. 1, as shown in fig. 2 and 3) to be inserted into two slots 202 of the limit groove 201 correspondingly. Since the leaves 109 of the first leaf spring assembly 101 and the second leaf spring assembly 102 shown in fig. 1 have been inserted into the slots 202 of the corresponding limit grooves 201 of the conductive housing 20, the leaves 109 are not visible in fig. 1.
The side of the conductive housing 20 is further provided with a plurality of reinforcing ribs 204, when the combined transmission assembly is mounted in the corresponding limit groove 201, reverse elastic force is generated between the first reed assembly 101 and the second reed assembly 102 due to compression of the elastic structure, so that the first shielding piece 103 and the second shielding piece 104 are reliably overlapped with the plurality of reinforcing ribs 204 of the conductive housing 20 and are in conductive connection with ground return, shielding and return effects are stably improved, and crosstalk is optimized.
Illustratively, the first reed assembly 101 and the second reed assembly 102 include at least one or more signal line pairs for transmitting differential signals, each signal line pair including two signal lines, one end of each signal line being connected to the reed, the other end of each signal line being connected to the fisheye terminal 107, and a plastic package for fixing the signal line pairs, the pair of signal lines corresponding to the two fisheye terminals 107.

It should be noted that, the metal housing 20 shown in fig. 1 includes four limiting grooves 201 for correspondingly mounting four transmission assemblies, and fig. 1 shows two of the transmission assemblies. However, the number of the limiting grooves 201 is not limited to the metal housing 20 of the present application.
The structure of the transmission assembly is described below by way of specific examples.
Fig. 2 is a schematic structural diagram of a transmission assembly according to the present application, as shown in fig. 2. Fig. 3 is a schematic diagram of a second embodiment of a transmission assembly according to the present application, as shown in the drawings.
The difference between fig. 2 and fig. 3 is that the resilient structure 105 shown in fig. 2 is a boss structure provided on the first face 1011 of the first leaf assembly 101 and/or the first face 1021 of the second leaf assembly 102. While figure 3 shows the elastic structure 105 as a separate elastic part.
The boss structure and the elastic part can be in the shape of a cylinder, a cube, a cuboid or a trapezoid, and the boss structure and the elastic part can be made of plastic, rubber and other flexible materials.
Specifically, the first reed assembly 101 is configured to transmit differential signals, and has a first surface 1011 and a second surface 1012, the first surface 1011 is provided with a plurality of positioning holes 1013, and the second surface 1012 is provided with a plurality of positioning posts 1014 (the positioning posts 1014 are numbered as shown in fig. 4 to 6).
The second reed assembly 102 is configured to transmit differential signals and has a first side 1021 and a second side 1022, the first side 1021 having a plurality of positioning posts 1024 that mate with the plurality of positioning holes 1013 of the first side 1011 of the first reed assembly 101, and the second side 1022 having a plurality of positioning posts 1024.
The at least one elastic structure 105 is configured to elastically fasten the first surface 1011 of the first reed assembly 101 and the first surface 1021 of the second reed assembly 102 under the fastening of the positioning hole 1013 of the first reed assembly 101 and the positioning post 1024 of the second reed assembly 102.
The first shield 103 is provided with locating holes 1031 that mate with the plurality of locating posts 1014 of the second face 1012 of the first reed assembly 101, and the first shield 103 is snapped into the first reed assembly 101 by the locating posts 1014 of the first reed assembly 101 and the locating holes 1031 of the first shield 103.
The second shield 104 is provided with locating holes 1041 that mate with the plurality of locating posts 1024 of the second face 1022 of the second reed assembly 102, and the second shield 104 is snapped into the second reed assembly 102 by the locating posts 1024 of the second reed assembly and the locating holes 1041 of the second shield 104.
In summary, at least one elastic structure 105 is disposed between the first reed assembly 101 and the second reed assembly 102, after the first reed assembly 101 and the second reed assembly 102 are buckled, the second face 1012 of the first reed assembly 101 and the second face 1022 of the second reed assembly 102 are buckled with the first shielding member 103 and the second shielding member 104, respectively, and finally the combined transmission assembly is mounted to the conductive housing 20 (as shown in fig. 1 and 6). Because the elastic structure 105 between the first reed assembly 101 and the second reed assembly 102 will form internal stress between the first reed assembly 101 and the second reed assembly 102, the first shielding member 103 and the second shielding member 104 are reliably and flexibly overlapped with the conductive shell, thereby stably improving shielding and reflow effects and optimizing crosstalk.
The combined transmission assembly is described in detail below.
Fig. 4 is a schematic structural diagram of a transmission assembly provided by the present application, and fig. 5 is a sectional view of a transmission assembly provided by the present application after being assembled. After the first reed assembly 101, the elastic structure 105 (the elastic structure 105 is disposed between the first reed assembly 101 and the second reed assembly 102, as shown in fig. 2 and 3), the second reed assembly 102, the first shielding member 103, and the second shielding member 104 are buckled, a first gap 106 is formed between the first reed assembly 101 and the second reed assembly 102.
Fig. 4 shows two sets of transmission assemblies, the two sets of transmission assemblies shown in fig. 4 also differ slightly due to the slightly different profile of the first reed assembly 101 and the second reed assembly 102, but the function of the resilient structure 105 between the first reed assembly 101 and the second reed assembly 102 of the two sets of transmission assemblies is the same. Fig. 5 shows a cross-section of the right set of transfer units of fig. 4. The first slit 106 shown in figures 4 and 5 is created by the resilient structure 105 between the first reed assembly 101 and the second reed assembly 102.
Fig. 6 is a cross-sectional view of the transmission assembly provided by the present application after being encased in a conductive housing, as shown in fig. 6. Fig. 6 illustrates two sets of transmission assemblies shown in fig. 4 mounted to the conductive housing 20, with a second gap 110 between the first reed assembly 101 and the second reed assembly 102, the second gap being smaller than the first gap 106, after each transmission assembly is mounted to a corresponding limit slot 201 of the conductive housing 20. That is, after the transmission assembly is mounted to the conductive housing 20, the first slit 106 between the first reed assembly 101 and the second reed assembly 102 is further pressed by the conductive housing 20 to obtain the second slit 110.
As can be seen from fig. 6, after the elastic structure is added between the first reed assembly 101 and the second reed assembly 102, the elastic structure forms an internal stress between the first reed assembly 101 and the second reed assembly 102, so that the first shielding member 103 and the second shielding member 104 are reliably and flexibly overlapped with the plurality of reinforcing ribs 204 on the side surface of the conductive housing 20 at the overlapped part 203, thereby stably improving the shielding and backflow effects and optimizing the crosstalk.
Therefore, the elastic structure is arranged between the first reed assembly and the second reed assembly, so that the first shielding piece and the second shielding piece are reliably overlapped with the plurality of reinforcing ribs of the conductive shell and are conducted to be grounded and reflowed, the shielding and reflow effects are stably improved, and crosstalk is optimized.
The foregoing embodiments are merely for illustrating the technical solution of the present application, but not for limiting the same, and although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that modifications may be made to the technical solution described in the foregoing embodiments or equivalents may be substituted for parts of the technical features thereof, and that such modifications or substitutions do not depart from the spirit and scope of the technical solution of the embodiments of the present application in essence.
