What are the application fields of wire harnesses?
1.Wire Harness:
It is used to connect two or more wires with components to transmit current or signals. It can simplify the assembly process of electronic products, make it easy for maintenance and upgrading, and improve the flexibility of design. It features high-speed and digital signal transmission, integration of various signal transmissions, miniaturization and microminiaturization of product volume, surface mount termination of contacts, modular combination, and convenient plugging and unplugging. It is used for internal connections in various household appliances, test instruments, equipment, computers and network equipment.
2.Industrial Wire Harness:
It mainly refers to some electronic wires, multi-core wires and flat cables with components inside cabinets. It is mostly used in cabinets of industrial uninterruptible power supplies (UPS), programmable logic controllers (PLC), control processors (CP), frequency converters, monitoring equipment, air conditioners, wind energy equipment and so on.
3.Automobile Wire Harness (Automobile Wire Harness):
The automobile wire harness is the network main body of the automobile circuit, also known as the low-voltage cable. Conventional automobile wire harness products have the characteristics of heat resistance, oil resistance and cold resistance. Meanwhile, it is quite flexible. It is used for internal connections in automobiles and can adapt to high mechanical strength and high-temperature environments.
4.LVDS Connecting Wire:
LVDS, namely Low Voltage Differential Signal, is a new technology that meets the requirements of high-performance data transmission applications nowadays. Compared with other competing technologies, the LVDS wire consumes much less power when providing high data rates. Products using LVDS wire technology can have data rates ranging from several hundred Mbps to over 2 Gbps. It has been widely applied in many liquid crystal display screens and other devices that require speed and low power consumption.
HDMI Cable Series
1.HDMI Connecting Wire:
2.HDMI, which stands for High Definition Multimedia Interface, is a fully digital video and audio transmission interface that can transmit uncompressed audio signals and video signals. HDMI wires can be connected to set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio systems and televisions.
3.HDMI Interface Definition:
HDMI D Type (Micro HDMI):
It has 19 pins and is mainly applied to some small mobile devices, such as video cameras, unmanned aerial vehicles, robots and so on. There are also special cases where one end is a standard HDMI plug and the other end is a Micro HDMI (D type) for industrial mobile phones.
HDMI C Type (mini-HDMI):
It also has 19 pins and is a s
hrunken version of the HDMIA type. It is mainly used in portable devices, for example, digital video cameras (DV), digital cameras, portable multimedia players and so on. Currently, the SONY HDR-DR5E digital video camera uses this specification of connector as the video output interface.
HDMI Cable Types:
Standard HDMI Cable:
It supports up to 1080/60i resolution.
Standard HDMI Cable with Ethernet.
Standard Automotive HDMI Cable.
High Speed HDMI Cable:
It supports 1080p, DeepColor and 3D.
High Speed HDMI Cable with Ethernet.
- With the development of 5G technology, which adopts the next-generation cellular technology and uses microwave transmission, it has a fast speed and a wide coverage area.
- The download speed of 5G can reach up to 10 Gbps. In the future, the mainstream application will be based on optical technology, that is, optical transmission technology, aiming to develop consumer electronic products that can bring the best experience to consumers. As the process of replacing copper with fiber is getting faster and more intensive, fiber optic connecting wires will surely become the mainstream of connecting wires within two to three years. For example, if you only need an HDMI wire that is two or three meters long, then there is no need to choose a fiber optic HDMI wire, and the traditional HDMI wire will be sufficient. However, if you need an HDMI wire longer than 10 meters, then the fiber optic HDMI wire will be your first choice. But when using such long-distance fiber optic HDMI wires, you need to pay attention to protection, do not fold them significantly, and be especially careful during pre-embedding in decoration. The corners should have a certain curvature and should not be folded vertically at a right angle. However, since the HDMI Association has relatively little research on optical cables, the quality of the current AOC series HDMI wires on the market is uneven.
- Working Principle of Fiber Optic HDMI
- For a fiber optic HDMI to output to the terminal of a display device, two processes are required: electricity -> light, and light -> electricity.
- Electricity -> light, light -> electricity; one is optical-to-electrical conversion and the other is electrical-to-optical conversion. On the right side is a three-color lamp, and on the left is an illuminating white lamp. The one on the right has an additional black component, which should be the microprocessor, the "brain" of the whole cable. With the combination of photoelectric conversion and the control of the microprocessor, the entire package is particularly small.
- Let's take a look at the internal structure of the fiber optic HDMI cable. There are a total of four layers. The innermost layer consists of 4 fiber optic cores. It's worth mentioning that when peeling off the fiber optic sheath, the fiber optic cores can be easily broken with just a little force. However, the fiber optic HDMI cable with a four-layer structure can well protect the fiber optic cores and prevent them from being crushed or pulled apart. Among them, the 4 fiber optics are very thin. The remaining tinned copper wires are used for power supply and electrical control signals, while the fiber optics are used for data transmission.
