What is the concept of the connector BNC interface

连接器BNC接口的概念是什么

I do not know how much you know about the concept of connector BNC interface, as an electronic components industry related practitioners should understand what the concept of BNC interface, the following professional and technical personnel of Deso Hardware Electronics BNC interface for you to introduce the concept of connector BNC interface. BNC (Basic Network Card) interface is a 10Base2 connector, that is, coaxial thin cable connector. Can be isolated from the video input signal, so that the signal interference with each other to reduce, and the signal bandwidth than the ordinary 15-pin D-type interface is larger, you can achieve a better signal response. This interface card should be used for fine coaxial cable as the transmission medium for the Ethernet or token network, this type of interface card is less common, mainly because of the use of fine coaxial cable as the transmission medium of the network is relatively small. Now mostly used in the security industry monitors to transmit video signals and cable TV indoor wall interface. Only some of the newer products in the 17-inch or more monitors have this interface. Its video signal input line by R, G, B and horizontal scanning, vertical scanning of five lines, this connector can be separated from the video of the three primary colors of the input signal, so that they are independent of each other, which can be maximized to avoid causing interference, so that the video input characteristics have been improved!

Comprehensive cabling system basics and construction?

综合布线系统基础知识及施工?

Comprehensive cabling system adopts an open star topology, in which each branch of the subsystem is a relatively independent operating unit. Comprehensive cabling system consists of six subsystems: workspace subsystem, horizontal zone trunk subsystem, management room subsystem, vertical trunk subsystem, equipment room subsystem and building complex subsystem. Comprehensive cabling system generally consists of several different functional components, including transmission media (unshielded twisted pair, large logarithmic cable and fiber optics, etc.) equipment connection hardware (such as distribution frames, connecting converters, adapters, standard information sockets, plugs, etc.) and the appropriate electrical protection equipment. These components constitute a variety of different functional subsystems, which have their own specific functions, the use of common standards for construction, so that it is easy to build the entire system, and can be continuously improved and upgraded according to changes in actual demand. With the development of modern technology, intelligent devices rely more and more seriously on the interconnection of the Internet, people's awareness of integrated wiring and requirements continue to improve, I believe that the openness, reliability and compatibility of integrated wiring technology will be further improved. 1, the work area subsystem (WorkLocation) work area subsystem is mainly responsible for completing the various information points and equipment terminals to match and connect. The system mainly includes the distribution of servers in the server room down the panel and information outlets (FD-TO), connecting information outlets and terminal equipment jumpers and adapters and other non-active accessories.

What are the main uses of connectors?

连接器的主要用处是什么?

Connector, that is, CONNECTOR, also known as the domestic connector, generally refers to electrical connectors. That is, the connection of two active devices, the device, the transmission of current or signal. It can be blocked in the circuit or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic equipment, cell phone connector product categories are divided into internal FPC connectors and board-to-board connectors. Affected by the smart phone demand market, the current development direction of cell phone connectors: low height, small pitch, multi-function, good electromagnetic compatibility, standardization and customization coexist. Cell phone board-to-board connector test, for its characteristics, available blade pin shrapnel micro-pin module for connection conduction.

IC Basics.

IC基础知识.

Generally speaking, our concept of IC only stays in it is a chip or integrated circuit, or the appearance of a variety of small things above. What exactly is it? Where does it come from? Why does it have various appearances? Our understanding may not be a lot, the following through the production process flow and its structure of the IC development of the history of the brief, I hope to let you have a preliminary grasp of the IC on the whole. First, the relevant concepts and classification of electronic components 1, the concept of electronic components: divided into semiconductor devices and electronic components, they are the basis for the development of the electronics industry, they are the basic unit of electronic equipment, belonging to the intermediate products of the electronics industry. IC (integrated circuits) is one kind of semiconductor devices in the electronic components. Microelectronics technology: the core technology of a country refers to microelectronics technology, and microelectronics technology refers to the technology that can deal with even smaller electromagnetic signals, the so-called microelectronics is distinguished from strong electricity (such as lighting electricity) and weak electricity (such as telephone lines). Microelectronics technology is represented by IC technology, the main product is IC. 2, Classification Electronic components are divided into two categories: semiconductor devices and electronic components Semiconductor devices include: semiconductor discrete devices, semiconductor integrated circuits, special function semiconductor devices, and other devices.

Model connector series--Model connector

航模连接器系列——模型接插件

In the world of modeling, there are many families of connectors, among which the EC, T and XT series of plugs are highly favored, such as EC2, EC3, EC5, XT30, XT60, XT90 and XT150. But how to ensure that our models are safe and damage-free in use, it is vital to understand the current carrying capacity of these plugs. Next, let's reveal the current specifications of these plugs: 1. EC2 Plugs
