Description

[0002] With the rapid development of Industry 4.0 and smart manufacturing, industrial control equipment is placing higher demands on the reliability and visualization of signal transmission. In applications such as rail transportation and automated production lines, equipment typically needs to monitor the status of a large number of I / O signals in real time, which presents new challenges for the functional integration of connectors.

[0003] Currently, 3U standard boards are widely used in industrial control, with extremely limited front panel space. The mainstream European connectors and D-Sub connectors currently in use are functionally limited, providing only electrical connections, and are bulky, lacking integrated status indication functions. Therefore, operators must use specialized equipment to check signal status, causing difficulties in on-site debugging and maintenance. Existing terminal connectors are smaller in size, but they typically use all-plastic shells, failing to provide electromagnetic shielding, making signals susceptible to interference and affecting system stability. Furthermore, their spring-loaded connection structure has poor mechanical stability, easily loosening under vibration, affecting the reliability of signal transmission.

[0004] Therefore, there is an urgent need for a new type of electronic connector that can integrate signal status display functions within a limited space, while also possessing good vibration resistance and shielding grounding capabilities, to meet the demand for highly reliable and easy-to-maintain connectors in industrial control and rail transportation fields.

[0034] In the application of 3U standard boards in rail transit signal control systems, their structural design exhibits typical modular packaging characteristics. The 3U board uses a standard 19-inch chassis package, with an overall height of 133.35mm. The PCB board carrying the electronic components is encapsulated inside the metal chassis and mechanically fixed to the chassis frame via mounting holes. High-density connectors are typically placed at the edges of the board; these connectors serve as critical interfaces for signal transmission, handling all electrical connections between the board and external devices. Due to the vertical space limitations of the 3U form factor, the height of these connectors is usually strictly controlled to within 25mm.

[0035] The chassis panel serves as the external enclosure for the entire unit and has interface windows corresponding to the internal connectors. The internal connectors connect to external cables through the openings.

[0036] This chassis structure provides excellent mechanical protection and environmental isolation, effectively resisting external physical impacts and protecting the internal circuit boards from damage. However, the rapid development of the power industry and the impact of the smart manufacturing industry in recent years have placed more stringent demands on the application of 3U boards. Especially in modern rail transit signal control systems, which are massive in size, a single equipment cabinet often needs to deploy dozens or even hundreds of I / O connection points. Taking a standard interlocking cabinet as an example, it may contain more than 200 signal terminals, which are densely arranged in a limited space. In such a high-density cabling environment, on-site debugging and troubleshooting are extremely difficult. Technicians not only need to rely on tools for testing, but sometimes also need to unpack and test the equipment. These tasks seriously affect the efficiency of debugging and maintenance. To address this issue, the industry has begun to modify connectors, hoping to integrate signal status display functions into the connectors themselves. However, since European connectors and D-Sub connectors are too large to integrate display functions, the smaller terminal connectors have been modified. At the same time, since terminal connectors have all-plastic shells and spring wire structures, their shielding performance and vibration resistance are insufficient. Therefore, while integrating display functions into existing terminal connectors, the shielding performance and vibration resistance of the terminal connectors are improved through design.

[0037] like Figure 1The 3U standard board in this embodiment includes a PCB board 101, a chassis panel 102, and an electronic connector assembly. In actual use, the chassis has an opening on one side, and the chassis panel 102 is fitted into the opening, forming a closed space. The PCB board 101 has several LEDs for displaying signal status. The chassis panel 102 also has holes through which the electronic connector assembly connects to the PCB board 101. Signals on the PCB board 101 are connected to external cables via the electronic connector assembly, enabling communication between the PCB signals and external devices.

[0038] like Figure 2 The electronic connector assembly of this application includes: a socket 3 and a plug 2, a metal housing and a wire clamping device; wherein the metal housing includes a housing body 401, a cover plate 402, a first wire clamping assembly 403, a second wire clamping assembly 404, and a fastening bolt 406, thereby forming a closed metal cavity structure to provide mechanical protection for the internal components.

[0039] The outer shell 401 has a first opening on its first side, and the plug 2 is located in the first opening. The plug 2 includes a plug shell 201 and a metal terminal 202. One end of the plug shell 201 has an opening facing into the shell cavity, and the metal terminal 202 is located on the opening side of the plug shell 201.

[0040] One end of socket 3 is soldered to the edge of PCB board 101, and the other end is connected to plug 2; Figure 3 The socket 3 includes a socket body 308, a through hole 301, a light guide post 302, a flange 303, a metal connector 304, a nut 305, and a metal pin 306. The socket body 308 has a through hole 301 along its width. The light guide post 302 has a bent structure, including a first part 30201 and a second part 30202. The first part 30201 is inserted into the through hole 301, and the second part 30202 is perpendicular to the PCB board 101. In this embodiment, the socket 3 has 16 light guide posts, each using 16 LEDs on the PCB board 101 as light sources. The port of the second part 30202 is suspended 3mm above the LEDs, thereby displaying the signal status on the PCB board 101 outside the chassis via the light guide post 302.

[0041] By installing a light guide post 302 on socket 3, the LED status light on PCB board 101 is transmitted to a visible external position on the connector, significantly improving the maintainability of the system. Maintenance personnel can quickly grasp the working status of each signal channel simply by observing the status indicator lights on the connector, without needing to open the chassis or use special tools. When an abnormality occurs in a channel, the corresponding indicator light will immediately display the abnormal status (such as off, flashing, or changing color), enabling rapid fault location. This visualization function demonstrates significant value in various scenarios such as daily operation and maintenance, emergency troubleshooting, and system debugging in rail transit.

[0042] Furthermore, in this embodiment, since the second part 30202 of the light guide column is suspended above the LED, the assembled light guide column 302 may rotate under the influence of environmental factors such as vibration and bumps. To prevent the light guide column 302 from rotating, such as... Figure 4 In this embodiment, the through hole 301 of the socket 3 is configured as a D-shaped through hole, and the first part 30201 of the light guide post is configured as a D-shaped structure, which is adapted to the D-shaped through hole structure of the socket 3. On the one hand, the D-shaped structure of the through hole 301 and the light guide post 302 enhances the stability of the light guide post 302 in the socket 3. On the other hand, the D-shaped configuration of the through hole 301 can reduce the space requirement of the display module in the socket and reduce the impact of the through hole 301 on the overall mechanical strength of the socket 3.

[0043] Furthermore, due to the dense arrangement of the 16 light guide columns 302 on the socket 3, the light sources between the light guide columns 302 will interfere with each other, thereby affecting the accuracy of the display, increasing the misjudgment rate of technicians, and affecting work efficiency. To solve this problem, in this embodiment, as follows... Figure 5 A plurality of isolation ribs 307 are arranged on the outer wall of the socket 3, with each isolation rib 307 positioned between two adjacent light guide pillars 302. In this embodiment, a total of 15 isolation ribs 307 are provided, arranged in parallel between the light guide pillars 302. The isolation ribs 307 effectively shield the light sources between adjacent light guide pillars 302, preventing mutual interference between light sources, thereby improving the accuracy of the display function and reducing the misjudgment rate of technicians.

[0044] Rail transit systems face an extremely complex electromagnetic environment during operation. The strong electromagnetic field intensity generated by the traction power supply system can reach 100V / m. High-frequency noise from high-power frequency converters during frequent train starts and stops, as well as transient overvoltages caused by lightning strikes and switching operations, pose severe challenges to signal transmission systems. This harsh operating environment compels engineers to pay close attention to the grounding network design of equipment. To compensate for the shortcomings of existing terminal connector shielding, the electronic connector assembly provided in this application offers multi-level grounding paths.

[0045] In this embodiment, the signal flows from the PCB board 101 through the socket 3, plug 2, and metal terminal 202 into the external cable, thereby realizing communication between the PCB board 101 and the external device. During the signal flow, it is subject to electromagnetic interference from the external environment, and the signal also radiates electromagnetic radiation into the external environment, affecting the performance of nearby devices and causing communication errors, sensor noise, etc. Therefore, a grounding network must be provided along this signal transmission path to provide continuous shielding.

[0046] In this embodiment, along the arrangement direction of the light guide columns 302, fixing flanges 303 are provided on both sides of the length direction of the socket 3, and metal connectors 304 are provided inside the flanges 303, such as... Figure 3 The metal connector 304 includes a flexible grounding piece 30402 and a grounding pin 30401. After the socket 3 is assembled with the chassis panel 102 and the PCB board 101, the flexible grounding piece 30402 is electrically connected to the external chassis through the chassis panel 102. The grounding pin 30401 is soldered into the grounding hole on the PCB board 101, so that the external chassis becomes a shield for the PCB board 101, realizing electromagnetic protection of the PCB circuit signals by the external chassis. At the same time, since the external chassis is a large-area conductor, it can provide a low-impedance reference plane for the PCB board 101, improving the signal integrity of the PCB circuit.

[0047] Furthermore, in this embodiment, to construct a grounding path between the metal casing and the external chassis, the socket 3 includes a nut 305 located within the flange 303. A fastening bolt 406 passes through a through-hole on the flange 303 and engages with the nut 305. Simultaneously, a metal connector 304 is placed between the fastening bolt 406 and the nut 305. On one hand, the engagement of the fastening bolt 406 and the nut 305 achieves a mechanical connection between the socket 3 and the metal casing. On the other hand, the metal connector 304 achieves an electrical connection between the metal casing and the external chassis, constructing a multi-level grounding path and further enhancing the anti-interference capability of the electronic connector assembly.

[0048] To achieve stable transmission of signals between the PCB circuit and external devices, a second opening is provided on the second side of the metal housing. A wire clamping device is installed at the second opening, and the size of the wire clamping device is set to be consistent with the size of the second opening, that is, the wire clamping device fills the second opening of the metal housing. The wire clamping device forms a wiring hole 405, through which external cables pass and connect to the wire clamping end of the metal terminal 202 inside the metal housing. The wiring hole 405 constrains the external cables, ensuring that the external cables are connected to the metal terminals in an orderly manner while improving the stability of the cable connection.

[0049] Furthermore, in this embodiment, in order to construct a grounding path between the external cable and the PCB grounding network, The wire pressing device includes a first wire pressing component 403 and a second wire pressing component 404. The first wire pressing component 403 is provided with a groove, and the second wire pressing component 404 is an upwardly arched arc-shaped metal sheet structure. The second wire pressing component 404 is disposed on the first wire pressing component 403, and the groove and the arc-shaped metal sheet structure cooperate to form a wire hole 405. The external cable includes a shielding layer, which connects a first clamping assembly 403 and a second clamping assembly 404. The first clamping assembly 403 and the second clamping assembly 404 secure the shielding layer of the external cable in the middle. The second clamping assembly 404 provides an electrical connection between the shielding layer of the external cable and the metal casing, thereby establishing a grounding path between the external cable shielding layer and the external chassis, providing a more complete shield for signal transmission from the PCB to external devices.

[0050] Furthermore, in this embodiment, the metal casing includes a casing body 401 and a cover plate 402. The cover plate 402 is disposed on the casing body 401 to form a cavity with openings at both ends. The cavity serves as a shield for the plug 2, the metal terminal 202, and the wire clamping device, providing electromagnetic protection for the transmission of signals from the socket 3 through the plug 2, the metal terminal 202, and the cable.

[0051] Multi-level grounding networks establish low-impedance loops in equipment, effectively controlling the consistency of signal reference potential, which enables equipment to better adapt to the unique electromagnetic environment and stringent reliability requirements of rail transit.

[0052] In engineering machinery and rail transit systems, the vibration resistance design of connectors is a key engineering challenge, stemming from the complex mechanical vibration environment generated during train operation. When trains pass through track joints, switches, or uneven sections at high speeds, the resulting vibration spectrum is broad and continuous. The external cables of the connectors are easily detached under bumps and impacts, thus interrupting signal transmission and potentially causing equipment downtime. Therefore, to improve the vibration resistance of electronic connector assemblies, the metal terminals 202 of the electronic connector assemblies adopt a pin-type connection structure.

[0053] In this embodiment, the socket 3 also includes a metal pin 306. The first end of the metal pin 306 is inserted into the socket body 308, and the second end is soldered to the PCB board 101. The plug 2 is provided with a terminal fixing hole that extends from the inside of the housing cavity to the outside of the housing cavity. The wire-pressing end of the metal terminal 202 is connected to an external cable, and the connector of the metal terminal 202 is fixed in the terminal fixing hole. When the plug 2 and the socket 3 are connected, the metal pin 306 and the connector of the metal terminal 202 are connected.

[0054] Compared to the spring-press connection of existing terminal connectors, the pin-type connection structure of the electronic connector assembly in this technical solution improves the vibration resistance of the electronic connector assembly, making the electronic connector better suited for harsh industrial equipment environments.

[0055] In 3U board applications, the number of metal pins 306 on the connector is limited due to the board size limitation. However, in actual application scenarios of connectors, it is often necessary to output multiple signals. In this embodiment, in order to increase the number of metal pins 306 in the socket 3, the metal pins 306 include two rows, long metal pins 30601 and short metal pins 30602. By setting two rows of metal pins, the number of points within the limited area of ​​the socket 3 is increased. This enables the electronic connector assembly to support parallel signal transmission with more points, improves data throughput, and adapts to the miniaturization requirements. At the same time, the socket 3 is connected to the PCB board 101 through more metal pins 306, which effectively improves the overall mechanical stability of the electronic connector assembly.
