The purpose of releasing static electricity can be achieved by using the electrostatic rod to discharge the static electricity from the car or other articles with static electricity into the earth through the human body. However, due to the high voltage of static electricity, which can reach tens of thousands of volts, the body can feel different static electricity...

The Set Top Box(STB) is a device that connects the TV set with an external signal source. It can convert compressed digital signals into television content and display it on the TV. From the simple functional set-top box that initially received digital television signals to the various set-top box HD players that are now versatile, with the development of set-top box technology, today's set-top boxes can complete many high-definition, interactive, multi-mode, multi-format decoding in data support. In terms of interface, in order to obtain more data sources, devices can generally provide many types of options. Generally, they can support USB, HDMI, Ethernet interfaces, hard disk interfaces, and the like...

Relays are widely used in the consumer electronics industry and industrial equipment. It has control systems(also known as input loops) and controlled systems(also known as output loops). It is actually an "automatic switch" that uses smaller currents to control larger currents.. Therefore, it plays the role of automatic adjustment, security protection, and conversion circuit in the circuit. Relays may be damaged by overflow or overpressure. Relays consist of one or more pairs of contacts and windings. When there is an electric current flowing through the winding, the contact will open or close. When the relay interrupts the current flowing to the perceptual load, a voltage tip pulse occurs, which is a common problem. In severe cases, the voltage tip Pulse will exceed the rated voltage of the relay contact, thereby damaging the contact. It can be sudden and severe, or very slow, and can take years to manifest...

As the name implies, the surge is an instantaneous overvoltage that exceeds the normal operating voltage. Its sources are divided into external sources(overvoltage generated on power lines such as lightning and switching operations in the power grid) and internal sources(air conditioners, elevators, welding machines, air compressors, and other responsive loads), according to statistics, In the United States: Due to direct losses such as shutdown, time loss, equipment maintenance, and premature replacement of equipment caused by power surges in various industries, the annual amount is as high as US$ 26 billion. In China, according to relevant statistics, in electrical products that have problems during the warranty period, 63 % of them are due to electrical surges. According to GB/T17626.5 IEC 61000-4-5 on surge(impact) resistance test, we have done some finishing and testing on low-voltage DC lightning protection scheme for everyone's reference...

According to the USB 2.0 standard, USB compliant power sources should be between 4.75 V and 5.25 V and provide a continuous current of at least 0.5 A. However, there are still some possible failures that could easily damage unprotected downstream electronic lines. Typical failures include: inductive peak voltage, connection to Gaodianya charger(user error), and connection to a power source whose power supply quality has been contaminated. Although the voltage of a typical calculator power supply is controlled at 5V + / -5 %, this does not mean that the voltage of the USB port does not exceed 5.25 V. The induced peak voltage tip can exceed 8V and damage peripherals that have not taken protective measures. The peak voltage phenomenon occurs when there is a certain inductance on the power bus and the current changes rapidly. The rapid change in current may come from external thermal plugging, internal system shutdown, or other internal power supply fluctuations. Electricity.

High-resolution multimedia interface(HDMI) is a non-compressed full-digital audio/video interface. It provides high-speed interfaces between video-audio source devices and receiving devices, such as connecting DVD players and digital displays. The current HDMI silicon chip has a digital signal transmission speed of 10.2 Gbps. Circuit manufacturers continue to reduce the minimum size of transistors, interconnections, and insulation layers in their devices, thus making the structure of high-speed devices smaller, eventually resulting in devices at lower energy levels that are also more vulnerable to breakdown. Damage.
