Description

Technical Field

[0001] The present invention relates to the technical field of signal line connection, and specifically to a signal line plugging and unplugging structure and a communication connection device. Background Art

[0002] The popularization of modern electronic devices has made signal line plugging and unplugging connectors an indispensable part of daily life. From personal computers to server networks, and then to various consumer electronic products, the quality of the connectors directly affects the performance of the devices and the user experience. However, there are still some common problems in the design of existing connectors, especially in scenarios of high-frequency signal transmission and frequent plugging and unplugging. They mainly include the following:

[0003] 1. Poor contact: Poor contact is one of the most common problems in connectors. Due to insufficient contact pressure between the pins and the sockets or surface oxidation, the resistance may increase, thus affecting the signal transmission efficiency and stability. Especially in harsh environmental conditions, such as high temperature, humidity or corrosive environments, the problem of poor contact will be more serious.

[0004] 2. Signal interference: With the continuous increase in data transmission rate, electromagnetic compatibility (EMC) has become an important consideration in the design of connectors. Existing connectors may have poor shielding effect, resulting in signal interference from external electromagnetic fields, which is likely to cause data transmission errors, reduce the signal integrity and the reliability of the system.

[0005] 3. Mechanical damage: During the plugging and unplugging process, improper operation or insufficient mechanical strength of the connector itself may cause pin bending, breakage or socket damage, which not only affects the service life of the connector, but may also pose greater safety risks, such as short circuit or equipment failure.

[0006] The Chinese invention with the publication number CN 112217040 B discloses a signal line plugging and unplugging structure and a communication connection device, including a male connector for fixing and connecting a signal line. A cable tube is connected to the lower side of the male connector. Both the male connector and the cable tube are hollow structures and are interconnected. The signal line is inserted into the interior of the male connector through the cable tube and is connected to a signal line plug. An installation plate is arranged inside the male connector. The installation plate includes two semi-circular fixing plates. One side of the fixing plate is provided with a clamping mechanism for connecting the two fixing plates to each other and connecting the installation plate to the male connector. In this invention, a signal line plug is connected and installed on the upper side of the male connector. The signal line plug is electrically connected to the signal line. A cable tube is connected to the lower side of the male connector. By rotating the cable bundling knob to adjust the closing of the lower end incision of the cable tube, the signal line is squeezed and fixed, facilitating the connection and installation of the signal line. However, although this invention mentions the fixation and connection of the signal line, it does not emphasize how to deal with electromagnetic interference. In an environment of high-density wiring or high electromagnetic noise, the lack of effective EMI protection may affect the integrity and stability of the signal, which is not conducive to long-term use.

[0046] Example 1

[0047] refer to Figure 1 and Figure 5 , this embodiment provides a signal line plug-in structure, which includes a connector 1, a locking assembly 2, a cable tie knob 3, a cable tie tube 4, and a signal line 5. The connector 1 is used to convert the electrical signal of the signal line 5 and connect it to an external device. The cable tie tube 4 is used to fix the signal line 5 through the cable tie knob 3 and connect it to the connector 1. It is worth noting that the connector 1 in this embodiment has a specific interface standard, such as RJ45, USB, HDMI, etc., which depends on the type and application requirements of the signal line 5. At the same time, the connector 1 is integrated with a signal conversion circuit to ensure that the electrical signal of the signal line 5 can be accurately converted into a signal format compatible with the external device, thereby achieving seamless connection with the external device. Furthermore, the cable tie tube 4 is a hollow structure, and a cutout is provided at its lower end to form a plurality of independently movable sheet structures. The cable tie knob 3 is installed on the outside of the cable tie tube 4 and is connected by a thread. When the harness knob 3 is rotated, it can move up and down along the external thread of the harness tube 4, thereby pressing the sheet structure at the lower end of the harness tube 4 to shrink inward, thereby squeezing the signal line 5 passing through, thereby achieving the purpose of fixing.

[0048] Specifically, one side of the outside of the connector 1 is fixedly connected to the side of the cable tie knob 3 through the locking assembly 2. The locking assembly 2 includes a fixed block 20 and an adjustable mechanism. Further, the fixed block 20 is used to align with the side of the cable tie knob 3 and is arranged inside the side of the cable tie knob 3. Specifically, the fixed block 20 is located on one side inside the cable tie knob 3, and its shape and size are designed to be able to align with the side of the cable tie knob 3 to ensure the stability and consistency of its connection. Further, elastic sheets 21 are arranged on both sides of the fixed block 20, the outer wall of the elastic sheet 21 fits with the inner wall of the cable tie knob 3, and the inner wall of the elastic sheet 21 fits with the end of the adjustable mechanism. In other words, the elastic sheet 21 is arranged on both sides of the fixed block 20, and when the side length of the fixed block 20 is adjusted, the elastic sheet 21 can provide a certain elastic force to ensure the close contact between the fixed block 20 and the inner wall of the cable tie knob 3, thereby enhancing the stability and reliability of the entire locking assembly 2.

[0049] The adjustable mechanism is used to adjust the side length of the fixed block 20, and its end fits against the inner wall of the wire-bundling knob 3. Specifically, the adjustable mechanism includes a positioning adjustment cavity 17, a positioning post 18, and a fixed ball 19. The fixed ball 19 is arranged on one side of the inner wall of the elastic piece 21. At the same time, positioning adjustment cavities 17 are arranged on both side edges of the two ends of the fixed block 20. The fixed ball 19 is connected to the positioning adjustment cavity 17 through the positioning post 18, and the adjustment handle on the positioning post 18 penetrates through the positioning adjustment cavity 17. At the same time, an adjustment spring 22 is arranged on one side of the positioning adjustment cavity 17, and the adjustment spring 22 is connected to the positioning post 18. Further, by adjusting the positioning post 18, the position of the fixed ball 19 in the positioning adjustment cavity 17 can be adjusted, so as to change the side length of the fixed block 20, and further ensure the firm connection between the wire-bundling knob 3 and the connector 1. Further, when it is necessary to adjust the side length of the fixed block 20, a force can be applied through the adjustment handle to compress the adjustment spring 22 by the positioning post 18, so as to change the position of the fixed ball 19, and further realize the adjustment of the side length of the fixed block 20.

[0050] Embodiment 2

[0051] Reference Figures 2 - 4 Referring to this, a signal line plugging and unplugging structure provided in this embodiment has the same structure as that in Embodiment 1. The difference is that one side inside the connector 1 is fixedly connected to the signal line 5 through the mounting plate 6. The mounting plate 6 is a key component of the signal line plugging and unplugging structure, which is used to fix the signal line 5 and reduce signal interference. The mounting plate 6 includes a plurality of uniformly distributed fixing holes 8 and a shielding component arranged between two adjacent fixing holes 8. The fixing holes 8 are used to fix the signal line 5. At the same time, a shielding layer is arranged on the outer wall of the fixing holes 8 to reduce crosstalk between the signal lines 5. The shielding component is used to reduce signal interference between two adjacent signal lines 5. It should be noted that the shielding layer arranged on the outer wall of the fixing holes 8 can be a conductive material coating or an embedded metal layer, which is used to reduce electromagnetic interference between the signal lines 5.

[0052] Specifically, a fastening component 9 is arranged on the fixing hole 8. The fastening component 9 includes a shielding ring 11 and an elastic ring 12. The shielding ring 11 is arranged inside the elastic ring 12, and the fixing hole 8 is arranged inside the shielding ring 11. At the same time, a plurality of reset springs 13 are uniformly distributed inside the elastic ring 12. The arrangement of the plurality of reset springs 13 can ensure that the signal line 5 is subjected to uniform pressure when inserted, so as to achieve good electrical contact and physical fixation. That is to say, the shielding ring 11 can not only be used to fix the signal line 5, but also reduce signal interference through the shielding layer thereon.

[0053] Furthermore, the shielding ring 11 includes a reverse fastener 14 and a fixing piece 16. The reverse fastener 14 is disposed on one side of the fixing piece 16. Meanwhile, the fixing hole 8 is arranged inside the fixing piece 16, and the fixing piece 16 is arranged inside the elastic ring 12. Further, the reverse fastener 14 includes a plurality of elastic pieces 15. The plurality of elastic pieces 15 are annularly distributed on the side of the fixing piece 16, and the size of the annular opening formed by the plurality of elastic pieces 15 is smaller than the aperture size of the fixing hole 8, so as to ensure the tight fixation and shielding effect when the signal line 5 is inserted. That is to say, when the signal line 5 is inserted, the elastic piece 15 will be slightly deformed, thereby generating a fastening force, and further ensuring good contact between the signal line 5 and the shielding ring 11.

[0054] In this embodiment, the shielding assembly includes a first shield wire 7 and a second shield wire 10, which are used to reduce signal interference between adjacent signal lines 5. Specifically, both the first shield wire 7 and the second shield wire 10 are arranged between two adjacent fixing holes 8. Meanwhile, the first shield wire 7 and the second shield wire 10 are oppositely arranged, and the signal polarities between the first shield wire 7 and the second shield wire 10 are opposite to cancel the interference caused by capacitive coupling and mutual inductance coupling. Further, the distance between the first shield wire 7 and the second shield wire 10 is specifically:

[0055]

[0056] where: C is the coupling capacitance between two adjacent signal lines, ε0 is the vacuum permittivity, ε r is the relative permittivity of the medium, A is the overlapping area between two adjacent signal lines, d is the distance between the first shield wire and the second shield wire, M is the mutual inductance between two adjacent signal lines, k is a proportionality constant, μ0 is the vacuum permeability, μ r is the relative permeability of the medium, l is the length of the signal line, and r is the radius of the signal line.

[0057] Embodiment 3

[0058] This embodiment provides a communication connection device, which includes the signal line plugging and unplugging structure provided in the above embodiment. Specifically, in this embodiment, the signal line plugging and unplugging structure is integrated into a communication connection device, which allows multiple signal line plugging and unplugging structures to be connected in series or in parallel through the signal line 5. At the same time, the signal line 5 adopts an S-shaped or Z-shaped structure to reduce the radiation and reception interference of high-frequency signals. It should be noted that the signal line 5 adopts an S-shaped or Z-shaped structure instead of a straight routing, which can increase the length of the signal line 5. That is to say, by alternately changing the direction of the signal line 5, the coupling of electromagnetic radiation and external interference can be effectively reduced, and the signal quality can be improved. That is, this design can not only improve the purity of the signal, but also enhance the flexibility and adaptability of the signal line plugging and unplugging structure, enabling it to perform optimally in various complex communication environments.

[0059] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
