What does the dc interface mean?
The DC interface is an interface that effectively outputs a fixed voltage after converting the input voltage.
It is composed of a horizontal jack It consists of a longitudinal socket, an insulating base, a fork-shaped contact spring, and a directional keyway. The two fork-shaped contact springs are positioned in the center of the base and are arranged vertically and horizontally and are not connected to each other. Widely used in mobile phones, MP3s, digital cameras, portable media players and other products.
One end of the fork-shaped contact spring of the DC interface is a wiring port, which is exposed on the top surface of the base cylinder and is used to connect the input power cord or cable. The other end of the fork-shaped contact spring is interconnected by the base body. It consists of an elastic arm, which is arranged in the insulated base jack in the direction of DC interface insertion, and is supplied to the equipment to make it work normally.
The DC interface can adopt three types of control according to needs. The PWM control type is highly efficient and has good output voltage ripple and noise. The PFM control type has the advantage of low power consumption even when used for a long time, especially when the load is small. The PWM/PFM conversion type implements PFM control when the load is small, and automatically switches to PWM control when the load is heavy.
The DC interface is a socket that matches a dedicated power supply and provides DC power supply to the equipment being used. That is the DC interface. DC means direct current.
Extension:
Interface generally refers to an abstraction that an entity provides itself to the outside world ( can be another entity) to separate the external communication method from the internal operation so that it can be modified internally without affecting the way other external entities interact with it. The interface between humans and information machines such as computers or between humans and programs is called user interface. The interface between hardware components of information machines such as computers is called hardware interface. The interface between software components of information machines such as computers is called software interface.
In computers, an interface is a shared boundary for information exchange between two independent components in a computer system. This exchange can occur between computer software and hardware, external devices or people operating them, or a combination of them. A user interface consists of a set of dials, knobs, operating system commands, graphics displays, and other devices that allow users to communicate with a computer or program. A graphical user interface (GUI) provides its user with a more or less "drawing-oriented" approach. For computer systems, GUI is usually a more satisfactory or user-friendly interface.

What are the internal interfaces of a computer motherboard? Recommended introduction to the internal interfaces of a computer motherboard
Mar 12, 2024 pm 04:34 PM
When we assemble the computer, although the installation process is simple, we often encounter problems in the wiring. Often, users mistakenly plug the power supply line of the CPU radiator into the SYS_FAN. Although the fan can rotate, it may not work when the computer is turned on. There will be an F1 error "CPUFanError", which also causes the CPU cooler to be unable to adjust the speed intelligently. Let's share the common knowledge about the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard. Popular science on the CPU_FAN, SYS_FAN, CHA_FAN, and CPU_OPT interfaces on the computer motherboard 1. CPU_FANCPU_FAN is a dedicated interface for the CPU radiator and works at 12V
Common programming paradigms and design patterns in Go language
Mar 04, 2024 pm 06:06 PM
As a modern and efficient programming language, Go language has rich programming paradigms and design patterns that can help developers write high-quality, maintainable code. This article will introduce common programming paradigms and design patterns in the Go language and provide specific code examples. 1. Object-oriented programming In the Go language, you can use structures and methods to implement object-oriented programming. By defining a structure and binding methods to the structure, the object-oriented features of data encapsulation and behavior binding can be achieved. packagemaini
Introduction to PHP interfaces and how to define them
Mar 23, 2024 am 09:00 AM
Introduction to PHP interface and how it is defined. PHP is an open source scripting language widely used in Web development. It is flexible, simple, and powerful. In PHP, an interface is a tool that defines common methods between multiple classes, achieving polymorphism and making code more flexible and reusable. This article will introduce the concept of PHP interfaces and how to define them, and provide specific code examples to demonstrate their usage. 1. PHP interface concept Interface plays an important role in object-oriented programming, defining the class application
Solution to NotImplementedError()
Mar 01, 2024 pm 03:10 PM
The reason for the error is in python. The reason why NotImplementedError() is thrown in Tornado may be because an abstract method or interface is not implemented. These methods or interfaces are declared in the parent class but not implemented in the child class. Subclasses need to implement these methods or interfaces to work properly. How to solve this problem is to implement the abstract method or interface declared by the parent class in the child class. If you are using a class to inherit from another class and you see this error, you should implement all the abstract methods declared in the parent class in the child class. If you are using an interface and you see this error, you should implement all methods declared in the interface in the class that implements the interface. If you are not sure which
Insight into Hongmeng system: actual function measurement and usage experience
Mar 23, 2024 am 10:45 AM
As a new operating system launched by Huawei, Hongmeng system has caused quite a stir in the industry. As a new attempt by Huawei after the US ban, Hongmeng system has high hopes and expectations. Recently, I was fortunate enough to get a Huawei mobile phone equipped with Hongmeng system. After a period of use and actual testing, I will share some functional testing and usage experience of Hongmeng system. First, let’s take a look at the interface and functions of Hongmeng system. The Hongmeng system adopts Huawei's own design style as a whole, which is simple, clear and smooth in operation. On the desktop, various
Inner class implementation of interfaces and abstract classes in Java
Apr 30, 2024 pm 02:03 PM
Java allows inner classes to be defined within interfaces and abstract classes, providing flexibility for code reuse and modularization. Inner classes in interfaces can implement specific functions, while inner classes in abstract classes can define general functions, and subclasses provide concrete implementations.
Java interfaces and abstract classes: revealing the inner connection between them
Mar 04, 2024 am 09:34 AM
Interface Interface defines abstract methods and constants in Java. The methods in the interface are not implemented, but are provided by the class that implements the interface. The interface defines a contract that requires the implementation class to provide specified method implementations. Declare the interface: publicinterfaceExampleInterface{voiddoSomething();intgetSomething();} Abstract class An abstract class is a class that cannot be instantiated. It contains a mixture of abstract and non-abstract methods. Similar to interfaces, abstract methods in abstract classes are implemented by subclasses. However, abstract classes can also contain concrete methods, which provide default implementations. Declare abstract class: publicabstractcl
Is there a class-like programming concept in Golang?
Mar 19, 2024 am 10:12 AM
In Golang (Go language), although there is no concept similar to classes in traditional object-oriented programming languages, similar functions can be achieved through structures and methods. In Golang, we can define a structure to encapsulate data, and define methods for the structure to manipulate data. This method can realize the basic functions of classes in object-oriented programming. First, let's look at a simple example, defining a structure named Person, containing two fields: name and age, and the Person structure
