Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal transmission technology, specifically to an insulator dielectric structure for transmitting high-speed differential signals. Background Technology
[0002] In the field of high-speed data transmission (such as communications, computers, consumer electronics, industrial control, etc.), differential signals are widely used in high-speed interfaces due to their advantages such as strong anti-interference ability, high transmission rate, and good timing accuracy.
[0003] When transmitting differential signals, the characteristic impedance must be matched to the nominal 100Ω in order to obtain good high-speed signal transmission performance. However, the traditional circular hole and circular needle configuration results in a large overall dielectric constant around the circular needle, which leads to a smaller characteristic impedance than the standard impedance, resulting in lower transmission efficiency of high-speed differential signals through insulators.
[0004] Meanwhile, the parallel arrangement of odd and even modules in traditional connection modules causes signal interference between them within a limited space, increasing the signal coupling path in signal transmission and resulting in poor practical performance of the insulator dielectric structure. Utility Model Content
[0005] To address the above problems, this utility model provides an insulator dielectric structure for transmitting high-speed differential signals, comprising an insulator, wherein an installation hole is provided in the middle of the insulator, and a positioning shell is connected to one end of the insulator;
[0006] The positioning shell has a connecting groove on one side, in which a plug is installed. The plug has several mating grooves on one side, each of which is a long, round tooth shape and is staggered.
[0007] Preferably, the mounting socket is equipped with a plurality of connection modules, the connection modules including a plurality of odd modules and a plurality of even modules.
[0008] Preferably, a plurality of the odd module groups and a plurality of the even module groups are installed alternately.
[0009] Preferably, one end of both the odd module group and the even module group is connected to a connector, and the connector is disposed in the through groove.
[0010] Preferably, the insulator has a mounting groove on its outer side, and two mounting strips are connected in the mounting groove.
[0011] Preferably, two guide pins are installed at one end of the insulator, and four positioning blocks are provided at one end of the insulator;
[0012] Preferably, two of the positioning blocks are arranged in an array and installed at one end of the insulator, and the other two positioning blocks are arranged symmetrically and installed at one end of the insulator.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This application changes the traditional circular hole and circular needle settings by using a docking groove, which can increase the air medium around the circular needle and improve the dielectric constant of the medium around the circular needle. This solves the problem that the traditional circular hole and circular needle settings have a large overall dielectric constant, resulting in a characteristic impedance that is smaller than the standard impedance. This is beneficial to improving the transmission efficiency of high-speed differential signals transmitted through insulators.
[0015] 2. This application uses staggered docking slots to coordinate the alternating arrangement of odd and even mode groups, which increases the physical spacing and isolation between differential pairs, thereby reducing the signal coupling path and solving the problem of signal interference between odd and even mode groups in a limited space when they are arranged side by side. This is beneficial to improving the practical performance of the insulator dielectric structure. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] Please see Figures 1 to 5An insulator dielectric structure for transmitting high-speed differential signals includes an insulator 1, with a mounting hole 2 in the middle of the insulator 1. After the connecting modules 7 are arranged, they are installed in the mounting hole 2 and connected to the insulator 1. It should be noted that after the connecting modules 7 are installed, their connectors 10 will pass through the plug 5, so that the connectors 10 are located in the mating groove 6. One end of the insulator 1 is connected to a positioning shell 3.
[0024] A slot 4 is provided on one side of the positioning shell 3. The slot 4 corresponds to the mounting hole 2 to ensure that the connection module 7 in the mounting hole 2 can be connected to the plug 5 through the slot 4. The plug 5 is installed in the slot 4. During connection, the insulator 1 is plugged into other connectors through the plug 5 to achieve the transmission of differential signals. The above connection to achieve signal transmission is a conventional means that can be understood and implemented by those skilled in the art based on common sense. Those skilled in the art can and should be clear about its specific function and structure, so it will not be described in detail here. A number of mating slots 6 are provided on one side of the plug 5. The mating slots 6 are all long and round teeth. The mating slots 6 are staggered. When transmitting differential signals, the insulator 1 needs to be plugged into other connectors. At this time, the mating slots 6 of the plug 5 will be plugged into other connectors, and the differential signal is transmitted through the connector 10 to the connection module 7.
[0025] It is important to note that the mating groove 6 is a long, round tooth shape, not the traditional arrangement of round hole and round needle (i.e., one connector 10 corresponds to one round hole). The connector 10 of the single odd module group 8 or even module group 9 corresponding to the groove 6 is located in the middle of the round tooth of the mating groove 6, and the connector 10 of the single odd module group 8 or even module group 9 is located in the corresponding single mating groove 6.
[0026] Specifically, the mating groove 6, when combined with the connector 10, increases the air medium around the connector 10, reduces the overall dielectric constant, thereby improving the characteristic impedance and obtaining a characteristic impedance closer to the nominal characteristic impedance of 100Ω, thus achieving good high-speed signal transmission performance.
[0027] More specifically, the staggered distribution of the docking slots 6 allows the odd-mode group 8 and even-mode group 9 to be arranged alternately. This results in the signal paths of adjacent differential pairs being opposite and the current directions being alternate, so the electromagnetic fields generated can cancel each other out. At the same time, the staggered arrangement increases the physical spacing and isolation between differential pairs, reduces the signal coupling path, and thus reduces mutual signal interference in a limited space.
[0028] The mounting socket 2 is equipped with several connection modules 7, which include several odd modules 8 and several even modules 9. The connection modules 7 change the dielectric constant of the transmission medium in the trace area by opening through slots on the return component and forming air cavities using the protrusion structure and groove of the odd modules 8 and even modules 9, so that the impedance of the connection modules 7 meets the requirements and the signal is transmitted to the load point as much as possible.
[0029] The connecting bridge in module 7 can shorten the return path and effectively reduce crosstalk. At the same time, the staggered distribution of the differential routing cavities of odd module 8 and even module 9 can also reduce interference between different differential pairs and improve signal integrity.
[0030] It should be noted that the connection module 7 is a well-known technology, and those skilled in the art can and should be clear about its specific functions and structure, so it will not be elaborated on here.
[0031] Several odd module groups 8 and several even module groups 9 are installed alternately.
[0032] Both odd module 8 and even module 9 are connected to one end of a connector 10, which is located in the distribution groove 4.
[0033] An installation groove 11 is provided on the outer side of the insulator 1, and two installation strips 12 are connected in the installation groove 11. The insulator 1 is positioned and installed by the installation strips 12 during the arrangement.
[0034] Two guide pins 13 are installed at one end of the insulator 1. When the insulator 1 is connected with other connectors, it is positioned and fixed by the guide pins 13. Four positioning blocks 14 are provided at one end of the insulator 1.
[0035] Two positioning blocks 14 are arranged in an array and installed at one end of the insulator 1. The other two positioning blocks 14 are symmetrically arranged and installed at one end of the insulator 1. The array distribution of the positioning blocks 14 is still symmetrical. Only the installation direction of one of the positioning blocks 14 needs to be adjusted. It should be noted that the two sets of positioning blocks 14 are not set in the same way because the two sets of positioning blocks 14 can restrict the angle orientation of other connectors to avoid mis-insertion.
[0036] When using this utility model:
[0037] First, the connecting module 7 is arranged and installed in the mounting socket 2 to connect with the insulator 1. After installation, the connector 10 of the connecting module 7 will pass through the plug 5, so that the connector 10 is located in the mating groove 6. The matching groove 4 corresponds to the mounting socket 2, thereby ensuring that the connecting module 7 in the mounting socket 2 can be connected to the plug 5 through the matching groove 4.
[0038] Secondly, when transmitting differential signals, the insulator 1 needs to be plugged into other connectors. At this time, the mating slot 6 of the plug 5 will be plugged into other connectors, and the differential signal will be transmitted through the connector 10 in conjunction with the connection module 7.
[0039] Then, the mating groove 6 is a long, round tooth shape, not the traditional arrangement of round hole and round needle (i.e., one connector 10 corresponds to one round hole). The connector 10 of the single odd module group 8 or even module group 9 corresponding to the groove 6 is located in the middle of the round tooth of the mating groove 6, and the connector 10 of the single odd module group 8 or even module group 9 is located in the corresponding single mating groove 6.
[0040] Finally, the mating groove 6, in its cooperation with the connector 10, increases the air medium around the connector 10, reduces the overall dielectric constant, thereby improving the characteristic impedance and achieving a characteristic impedance closer to the nominal characteristic impedance of 100Ω, thus resulting in good high-speed signal transmission performance. The staggered distribution of the mating grooves 6 allows the odd-mode group 8 and even-mode group 9 to be arranged alternately, so that the signal paths of adjacent differential pairs are opposite and the current directions are alternating, and the resulting electromagnetic fields can cancel each other out. At the same time, the staggered arrangement increases the physical spacing and isolation between differential pairs, reduces the signal coupling path, and thus reduces mutual signal interference in a limited space.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
