Description

Technical Field

[0001] This application relates to the field of electrostatic discharge protection technology for display and control consoles, and more specifically, to an anti-static display and control console and a protection method thereof. Background Technology

[0002] Static electricity attracts dust, reducing the insulation resistance of components and shortening their lifespan. Static discharge can also damage electronic components in the display console, causing them to malfunction. While some electronic components can withstand the electrostatic discharge voltage, most have a voltage range of several hundred to several thousand volts, whereas static electricity generated by human activity in a dry environment can reach several thousand or even tens of thousands of volts. Some electronic components cannot withstand such high voltages. The electromagnetic field generated by electrostatic discharge has a large amplitude (several hundred volts / meter) and an extremely wide spectrum (from tens of megawatts to several gigabits), causing interference or even damage to the display console. To avoid interference or damage from static electricity, the display console must be designed with anti-static properties to ensure its normal operation and expected lifespan. Summary of the Invention

[0003] One objective of this invention is to provide an anti-static display and control console to solve the technical problem of existing display and control consoles being affected by electrostatic interference or even damaged. Another objective of this invention is to provide a protection method for the anti-static display and control console.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This invention provides an anti-static display and control console, the display and control console comprising:

[0006] A housing, wherein a first conductive part is provided on the housing;

[0007] An external interface is fixedly attached to the housing, and a second conductive part is connected to the external interface, which is grounded through the second conductive part;

[0008] A control component located inside a housing, the control component including a first protective shell for isolating the control component from external electrostatic discharge, the first protective shell including a circuit board and electronic components located on the circuit board;

[0009] The electronic component includes pins connected to an electrostatic discharge (ESD) protection component and a second protective shell for isolating external ESD from the electronic component. A third conductive part is provided on the second protective shell, and the third conductive part of the electronic component is grounded.

[0010] Optionally, the second conductive part is a grounding bolt.

[0011] Optionally, the control component further includes an external connector with an electrostatic sensitive device, and the external connector is provided with an electrostatic protection structure.

[0012] Optionally, the external interface includes a control panel, on which a fourth conductive part is provided, and the fourth conductive part is grounded.

[0013] Optionally, a fifth conductive part is provided on the first protective shell, and the fifth conductive part is grounded.

[0014] The present invention also provides a method for protecting an anti-static display console, the method comprising:

[0015] Non-electrostatic sensitive devices are selected as the control components of the display and control console;

[0016] When transporting electrostatic sensitive devices to the display and control console, the electrostatic sensitive devices should be packaged in an anti-static manner.

[0017] Grounding structures are installed on the housings and external interfaces of each component of the display and control console, and electrostatic protection components are connected to the pins of electronic components;

[0018] When assembling and soldering the circuit board of the display console, ensure that the conductive parts of the display console are grounded.

[0019] Alternatively, an anti-static workbench can be used when soldering circuit boards, while keeping the anti-static workbench constantly grounded.

[0020] Optionally, the display console can be isolated from static electricity generated during soldering operations.

[0021] Optionally, when transporting circuit board assemblies, the circuit boards are packaged in anti-static packaging and placed on anti-static trays.

[0022] Optionally, the circuit boards can be anti-static packaged in anti-static bags or anti-static packaging boxes. The beneficial effects of this application are as follows:

[0023] Compared with existing technologies, this invention isolates and dissipates static electricity generated by the display console by setting pins connected to electrostatic discharge (ESD) protective components and adding grounding structures to the housings and external interfaces of each component. This prevents the display console from being interfered with or damaged by ESD. Furthermore, this invention selects non-ESD-sensitive components for the control components, grounds the conductive parts of the display console during circuit board assembly, and provides anti-ESD packaging for ESD-sensitive components during transport. Combined with the protective structures added to the display console, both external factors and the structure itself provide ESD protection, resulting in superior ESD protection for the display console.

[0029] In the following description, numerous specific details are set forth for illustrative purposes and to provide a comprehensive understanding of one or more embodiments. However, it will be apparent that these embodiments can also be implemented without these specific details.

[0030] In the description of this application, it should be noted that the terms "upper," "lower," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0031] It should also be noted that, in the description of this application, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0032] To address the problems existing in the current technology, such as Figure 1-4As shown, one embodiment of the present invention provides an anti-static display and control console, which includes: a housing 1, on which a first conductive part 101 is provided, the first conductive part 101 being a conductive structure connected to the ground, specifically a copper block or an aluminum block. An external interface 2 (aerospace socket or socket) is fixed to the housing 1. A second conductive part 201 is connected to the external interface 2. The second conductive part 201 extends along the side wall of the display and control console housing 1 to the ground. The external interface 2 is grounded through the second conductive part 201. Specifically, the second conductive part 201 is a grounding bolt. The control component 3 is located inside the housing 1. The control component 3 includes a first protective shell 301 for isolating the external static electricity of the control component 3. A fifth conductive part 304 is provided on the first protective shell 301. The fifth conductive part 304 is grounded. The first protective shell 301 includes a circuit board 302 (printed board) and electronic components located on the circuit board 302. The electronic components include static electricity sensitive devices and non-static electricity sensitive devices. It can be understood that static electricity sensitive devices are components that are sensitive to static electricity (static electricity sensitive devices are abbreviated as SSD). Static electricity sensitive devices are mainly very large-scale integrated circuits, especially metallized film semiconductor (MOS) circuits. For example, the electrostatic discharge (ESD) sensitivity range of MOSFETs is 100-200V, that of field-effect transistors is 140-10000V, and that of CMOS circuits is 25-20000V. Based on the ESD limit voltage (also known as ESD sensitivity) that an SSD can withstand without being damaged, SSDs are classified into three levels. Corresponding ESD protection measures are taken for different sensitivity levels. The ESD protection of the electronic components in this invention includes pins 305 connected to an ESD protection component and a second protective shell 303 for isolating external ESD from the electronic components. The pins 305 of the ESD-sensitive components on the circuit board 302 are connected to a TVS diode for protection. A third conductive part 306 is provided on the second protective shell 303, and the third conductive part 306 of the electronic components is grounded.

[0033] Control component 3 also includes an external connector with an electrostatic sensitive device. The external connector is equipped with an electrostatic protection structure, specifically an electrostatic protection cap. This cap prevents the external connector from being interfered with by electrostatic discharge. Furthermore, the electrostatic protection cap is made of an electrostatic-resistant material. External interface 2 includes a control panel with a fourth conductive part (not shown in the figure) grounded to the computer assembly and power control module. Each external interface 2 is equipped with a separate grounding bolt device to ensure a safe and reliable grounding measure for electrostatic discharge. The bolt device is a bendable or expandable conductor structure; this technology is well-known to those skilled in the art and will not be described in detail here. Furthermore, the good contact between the display console body and the metal connection surfaces of the computer assembly, display assembly, and power control module ensures that static electricity generated inside the display console flows smoothly into the console's housing. With good grounding of the console body, static electricity generated by each component of the display console flows smoothly to the ground, preventing the accumulation of static electricity inside the display console, which could interfere with its normal operation or even damage it.

[0034] In one specific embodiment, the third conductive part 306 is connected to the first protective shell 301, and the fifth conductive part 304 and the fourth conductive part on the first protective shell 301 are connected to the housing 1 of the display console.

[0035] When static electricity flows out, the static electricity generated by the electronic components of the control assembly is conducted sequentially through the second protective shell 303, the third conductive part 306, the first protective shell 301, and the fifth conductive part 304 to the housing 1 and finally flows into the ground through the first conductive part 101. The static electricity generated by the control panel is conducted to the housing 1 through the fourth conductive part and finally flows into the ground through the first conductive part 101.

[0036] like Figure 4 As shown, the present invention also provides a method for preventing electrostatic interference on a display and control console, the method comprising:

[0037] Non-static-sensitive devices are selected as the control components 3 of the display and control console. Furthermore, when selecting components, non-static-sensitive devices (specifically, components with shielded housings and insensitive to static electricity) are given priority.

[0038] During the selection process, critical electronic components were chosen with appropriate levels of electrostatic discharge (ESD) protection. Specifically, the key electronic components of the display console include the CPU D2000 and the CS32F103 series microprocessor. The CPU D2000 meets the ESD sensitivity level of Class 1C (1000V) as specified in GJB 7400-2011, while the CS32F103 meets the ESD sensitivity level of Class 2 (2000V) as specified in GJB 7400-2011. Grounding structures were installed on the housings 1 and external interfaces 2 of each component of the display console, and ESD protection devices were connected to the pins 305 of the electronic components. Specifically, the ESD protection devices are TVS diodes, which protect the electronic components from damage caused by transient high-energy ESD shocks.

[0039] When assembling and soldering the circuit board 302 of the display console, the conductive parts of the display console should be kept in a grounded state. During this process, static electricity should be continuously conducted to the ground. Do not touch the components with bare hands when soldering the circuit board 302. When using an anti-static workbench, keep the anti-static workbench in a grounded state so that the static electricity generated by the workbench can continuously flow into the ground. In addition, it is necessary to have personnel with professional skills to perform the soldering work of the circuit board 302.

[0040] When transporting electrostatic sensitive devices on the display and control console, anti-static packaging should be used. It should be noted that anti-static packaging is especially necessary for circuit board 302 when transporting various structural components of the display and control console.

[0041] When transporting the components of the display and control console, the components are packaged with anti-static materials to avoid the generation and interference of static electricity during transportation.

[0042] Furthermore, when transporting the circuit board 302 assembly, it is necessary to use anti-static bags or special packaging boxes and anti-static trays for circuit board 302. Specifically, use anti-static packaging bags or special packaging boxes for circuit board 302 to package the circuit board 302 and place it on an anti-static tray for transportation.

[0043] Antistatic packaging bags are made of multiple layers of composite material, including a base material, a metal coating layer, and a heat-sealing layer. This composite material can shield against external static electricity and prevent static electricity itself. In addition, antistatic packaging bags can also be made of PE antistatic plastic bags.

[0044] Specifically, to avoid static electricity from external factors on the display and control console, and to isolate the display and control console from static electricity generated by soldering operations, the following measures should be taken: when debugging circuit board 302, wear an anti-static wrist strap; operators should wear anti-static wrist straps during operation; conduct regular training and inspections for personnel in each position to reduce interference from static electricity carried by the operators themselves; and select anti-static wrist straps, anti-static workbenches, and contact-type static discharge equipment that meet the requirements for anti-static production and debugging.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
