Description

Technical Field

[0001] This application relates to the technical field of connectors, and in particular to a signal transmission connector. Background Art

[0002] Signal transmission connectors are widely used in communication technologies. They are a type of connector commonly used in large communication equipment, ultra-high performance servers, supercomputers, industrial computers, and high-end storage devices. Their main function is to connect a single board and a backplane. The single board and the backplane form a 90-degree vertical structure to transmit high-speed differential signals or single-ended signals and to transmit large currents.

[0003] As the communication frequency gradually increases, crosstalk between signals and external interference on signals will affect the signal transmission rate. A signal transmission connector with a conventional structure cannot ensure effective signal transmission. Therefore, it is necessary to provide a signal transmission connector that can ensure effective signal transmission, improve shielding and return effects, and optimize crosstalk.

[0039] To make the objectives, technical solutions and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application with reference to the accompanying drawings in this application. Apparently, the described embodiments are some, rather than all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in this application belong to the scope of protection of this application.

[0040] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned accompanying drawings are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order different from that shown or described here.

[0041] To solve the problem of the reliability of the shielding lap joint of a signal transmission connector in a limited space, this application provides a signal transmission connector. By arranging an elastic structure between the first reed component and the second reed component, when the transmission component composed of the first reed component, the second reed component, the elastic structure, the first shielding member and the second shielding member is inserted into the corresponding limiting groove of the metal housing, the first shielding member and the second shielding member can both achieve reliable flexible lap joints with the conductive housing, thereby ensuring the effective transmission of signals, improving the shielding and return effect, and optimizing crosstalk.

[0042] The following combines Figures 1-6 to describe the signal transmission connector of this application.

[0043] Figure 1 is a schematic structural diagram of the signal transmission connector provided by this application, as Figure 1 shown. Figure 1 The shown signal transmission connector includes a transmission component and a conductive housing 20.

[0044] Exemplarily, each transmission component includes a first reed component 101, an elastic structure 105 ( Figure 1 not shown, as Figure 2 , Figure 3 shown), a second reed component 102, a first shielding member 103, and a second shielding member 104. Since Figure 1 the shown transmission component has already combined the first reed component 101, the elastic structure 105, the second reed component 102, the first shielding member 103, and the second shielding member 104, and the elastic structure 105 is sandwiched between the first reed component 101 and the second reed component 102, so Figure 1 it cannot be seen.

[0045] The conductive housing 20 is provided with a plurality of limiting grooves 201, each limiting groove 201 has two slots 202, and each limiting groove 201 corresponds to a transmission component. Both the bottom of the first reed component 101 and the second reed component 102 are provided with two reeds 109( Figure 1 not shown, such as Figure 2 , Figure 3 shown) to correspondingly insert into the two slots 202 of the limiting groove 201. Since Figure 1 the reeds 109 of the shown first reed component 101 and second reed component 102 have been inserted into the slots 202 of the corresponding limiting grooves 201 of the conductive housing 20, so Figure 1 the reeds 109 cannot be seen.

[0046] The side of the conductive housing 20 is further provided with a plurality of reinforcing ribs 204. When the combined transmission component is installed into the corresponding limiting groove 201, a reverse elastic force will be generated due to the compression of the elastic structure between the first reed component 101 and the second reed component 102, so that both the first shielding member 103 and the second shielding member 104 can achieve reliable lap joint and conduction grounding return with the plurality of reinforcing ribs 204 of the conductive housing 20, thereby stably improving the shielding and return effect and optimizing crosstalk.

[0047] Exemplarily, the first reed component 101 and the second reed component 102 include at least one pair or more of signal line pairs and a plastic package for fixing the signal line pairs. These signal line pairs are used to transmit differential signals. Each signal line pair includes two signal lines. One end of the signal line is connected to the reed, and the other end of the signal line is connected to the fish-eye terminal 107. One pair of signal lines corresponds to two fish-eye terminals 107. The first shielding member 103 and the second shielding member 104 include at least one ground fish-eye 108, and the ground fish-eye 108 and the fish-eye terminal 107 are arranged at intervals. One end of the signal line is connected to another signal transmission connector through the reed, and the other end of the signal line is connected to the PCB board through the fish-eye terminal 107, thereby realizing signal transmission.

[0048] Specifically, one fish-eye terminal 107 on the first reed component 101 and one fish-eye terminal 107 at the corresponding position on the second reed component 102 form a pair of fish-eye terminals for transmitting differential signals.

[0049] It should be noted that Figure 1 the shown metal housing 20 includes four limiting grooves 201 for correspondingly installing four transmission components, while Figure 1 only two of the transmission components are shown. However, the number of the limiting grooves 201 of the metal housing 20 in the present application is not limited.

[0050] The structure of the transmission component will be described below through specific embodiments.

[0051] Figure 2 is one of the schematic structural diagrams of the transmission component provided by this application, as Figure 2 shown. Figure 3 is the second schematic structural diagram of the transmission component provided by this application, as shown in the figure.

[0052] Figure 2 and Figure 3 The difference between them is that: Figure 2 The elastic structure 105 shown is a boss structure provided on the first surface 1011 of the first reed component 101 and / or the first surface 1021 of the second reed component 102. While Figure 3 The elastic structure 105 shown is an independent elastic part.

[0053] The shapes of the above-mentioned boss structure and elastic part can be a cylinder, a cube, a cuboid or a frustum of a pyramid, and their materials can be flexible materials such as plastic and rubber.

[0054] Specifically, the first reed component 101 is used to transmit differential signals, and has a first surface 1011 and a second surface 1012. A plurality of positioning holes 1013 are provided on the first surface 1011, and a plurality of positioning posts 1014 are provided on the second surface 1012 (the reference numerals of the positioning posts 1014 are as Figures 4-6 shown).

[0055] The second reed component 102 is used to transmit differential signals, and has a first surface 1021 and a second surface 1022. The first surface 1021 is provided with positioning posts 1024 that match the plurality of positioning holes 1013 on the first surface 1011 of the first reed component 101, and the second surface 1022 is provided with a plurality of positioning posts 1024.

[0056] At least one elastic structure 105 is elastically buckled between the positioning holes 1013 of the first reed component 101 and the positioning posts 1024 of the second reed component 102, so as to realize the elastic buckling between the first surface 1011 of the first reed component 101 and the first surface 1021 of the second reed component 102.

[0057] The first shielding member 103 is provided with positioning holes 1031 that match the plurality of positioning posts 1014 on the second surface 1012 of the first reed component 101, and the first shielding member 103 and the first reed component 101 are buckled through the positioning posts 1014 of the first reed component 101 and the positioning holes 1031 of the first shielding member 103.

[0058] The second shielding member 104 is provided with positioning holes 1041 that match the plurality of positioning posts 1024 on the second surface 1022 of the second reed component 102, and the second shielding member 104 and the second reed component 102 are buckled through the positioning posts 1024 of the second reed component and the positioning holes 1041 of the second shielding member 104.

[0059] In summary, at least one elastic structure 105 is provided between the first reed component 101 and the second reed component 102. After the first reed component 101 and the second reed component 102 are buckled together, the first shielding member 103 and the second shielding member 104 are respectively buckled on the second surface 1012 of the buckled first reed component 101 and the second surface 1022 of the second reed component 102. Finally, the assembled transmission component is installed in the conductive housing 20 (as Figure 1 , Figure 6 shown). Since the elastic structure 105 between the first reed component 101 and the second reed component 102 will form internal stress between the first reed component 101 and the second reed component 102, the first shielding member 103 and the second shielding member 104 can both achieve reliable flexible lap joints with the conductive housing, thereby stably improving the shielding and return effect and optimizing crosstalk.

[0060] The following is a specific description of the assembled transmission component.

[0061] Figure 4 FIG. is a schematic structural diagram of the assembled transmission component provided by the present application, Figure 5 and FIG. is a sectional view of the assembled transmission component provided by the present application. After buckling the above-mentioned first reed component 101, elastic structure 105 (the elastic structure 105 is provided between the first reed component 101 and the second reed component 102, as Figure 2 , Figure 3 shown), second reed component 102, first shielding member 103 and second shielding member 104, it can be seen that there is a first gap 106 between the first reed component 101 and the second reed component 102.

[0062] Figure 4 FIG. shows two sets of transmission components. Since the outer shapes of the first reed component 101 and the second reed component 102 are slightly different, Figure 4 the two sets of transmission components shown are also slightly different, but the functions of the elastic structures 105 between the first reed component 101 and the second reed component 102 in the two sets of transmission components are the same. Figure 5 FIG. shows Figure 4 the sectional view of the right set of transmission components. Figure 4 and Figure 5 The first gap 106 shown is generated by the elastic structure 105 between the first reed component 101 and the second reed component 102.

[0063] Figure 6 FIG. is a sectional view of the transmission component provided by the present application after being installed in the conductive housing, as Figure 6 shown. Figure 6 It is Figure 4The two sets of transmission components shown are installed on the conductive housing 20. After each transmission component is installed in the corresponding limiting groove 201 of the conductive housing 20, there is a second gap 110 between the first reed component 101 and the second reed component 102, and the second gap is smaller than the first gap 106. That is to say, after the transmission component is installed on the conductive housing 20, the first gap 106 between the first reed component 101 and the second reed component 102 will be further pressed by the conductive housing 20 to obtain the second gap 110.

[0064] From Figure 6 It can be seen that after the elastic structure is added between the first reed component 101 and the second reed component 102, the elastic structure forms internal stress between the first reed component 101 and the second reed component 102, causing both the first shielding member 103 and the second shielding member 104 to achieve reliable flexible lap joints with multiple reinforcing ribs 204 on the side of the conductive housing 20 at the lap joint 203, thereby stably improving the shielding and return effect and optimizing crosstalk.

[0065] Thus, it can be seen that the purpose of setting the elastic structure between the first reed component and the second reed component in this application is to enable both the first shielding member and the second shielding member to achieve reliable lap joints and conduct grounding return with multiple reinforcing ribs of the conductive housing, thereby stably improving the shielding and return effect and optimizing crosstalk.

[0066] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
