Main Types and Instructions of Electronic Connectors

Have you ever heard electronic connectors? Does it sound familiar to you? If you don't quite understand what is it mean, don't worry, this article will solve your confuse. We're going to show you different types of electronic connectors and describe them in details. 

 

What are Electronic Connectors? 

An electrical connector, also known as a circuit connector, is a conductor device that bridges two conductors on a circuit so that current or signals can flow from one conductor to the other. An electrical connector is a motor system that provides a separable interface to connect two sub-electronic systems. In general terms, the component used to complete the electrical connection between circuits or electronic machines is called a connector, or a bridge between the two. 

Types of Electronic Connectors 

There is a wide variety of electrical connectors on the market, mainly from the shape, structure and application for classification. Due to space, the following is only about the classification of electrical connectors from the perspective of use, which is:

• Sealed electrical connector

• High temperature electrical connector

• Filter electrical connector

• HDMI electrical connector

• Displayport electrical connector

• DGA electrical connector

Sealed Electrical Connector

The most special feature of the sealed circuit connector is that it has a special rubber seal that keeps out wet weather, dust and dirt to ensure that the circuit can be safely connected in both wet, rainy and dusty areas.

Sealed electrical connector are commonly used in applications where environmental protection and durability are crucial, such as: 

  

• Automotive industry

• Marine and underwater applications

• Aerospace and defense

  

Sealed electrical connectors come in various types and sizes, such as circular connectors, rectangular connectors, and modular connectors, to accommodate different applications and requirements.  

 

High temperature electrical connector 

 
High temperature electrical connectors are made by using materials such as ceramic, nickel alloy or stainless steel; they are also constructed using a press molding process that allows them to maintain electrical connections without damaging the machine even when exposed to high temperatures. 

  

High-temperature connectors are typically used in applications where the environment or the equipment generates significant heat, such as: 

  

• Industrial processes

• Aerospace and defense

• Automotive industry 

• Oil and gas industry

• Electronics

  

High-temperature electrical connectors are made with materials that can endure high temperatures without losing their mechanical strength or electrical conductivity. These materials include high-temperature plastics, ceramics, or metal alloys. The contacts within the connectors are often made of materials with high melting points, such as gold or platinum, to ensure reliable electrical connections at high temperatures. Additionally, these connectors may incorporate heat-resistant seals, gaskets, or insulation to maintain their performance in extreme conditions.

Filter electrical connector 

A filter electrical connector is a specialized type of connector that combines the functionality of an electrical connector with that of an EMI （Electromagnetic Interference） or RFI （Radio Frequency Interference） filter. These connectors are designed to provide both a reliable electrical connection and protection against electromagnetic or radio frequency interference, which can negatively affect the performance of electronic systems or cause malfunctions. 

  

Filter electrical connectors typically incorporate capacitors, inductors, or ferrite beads into their design, which help to attenuate or block unwanted noise, signals, or interference. By filtering out these undesirable signals, filter connectors help to maintain the integrity of the data or power being transmitted through the connection, ensuring the proper functioning of the connected devices or components. 

  

These connectors are particularly useful in applications where sensitive electronic equipment is used, or where strict EMI/RFI regulations must be met, such as: 

  

• Aerospace and defense

• Medical equipment

• Telecommunications

• Industrial applications  

• Consumer electronics

  

Filter electrical connectors are available in various types, sizes, and configurations, such as circular connectors, D-sub connectors, or modular connectors, to accommodate different applications and requirements. When selecting a filter connector, it is essential to consider factors like the required filtering performance, the frequency range, and the connector's mechanical and environmental specifications. 

 

 

HDMI Connector

HDMI is a digital interface standard that was first introduced in 2002. It is designed to transmit high-quality audio and video signals between different devices, such as computers, TVs, gaming consoles, and more. The HDMI standard has evolved over the years, with each new version bringing improvements in bandwidth, resolution, and audio quality. 

 

HDMI cables and ports are used in a wide range of applications，such as： 

 

• Home entertainment systems 

• Commercial installations 

• Professional audio and video setups 

 

You can use an HDMI cable to connect your computer to your TV and stream high-definition video content, or connect your gaming console to your TV to enjoy immersive gaming experiences！ 

 

HDMI has become the de facto standard for high-definition multimedia connectivity, and its ability to support high-quality video and audio signals has made it an essential component of modern digital devices. With each new version of the standard, HDMI continues to evolve, providing improved bandwidth, resolution, and audio quality for an ever-expanding range of applications. 

DisplayPort  Connector

DisplayPort is a digital display interface standard that was first introduced in 2006. It was designed to replace the older VGA and DVI standards and to provide a more advanced digital display interface for modern devices. DisplayPort has evolved over the years, with each new version bringing improvements in bandwidth, resolution, and other features. 

 
Application: 

 

• High-end monitors 

• Laptops 

• Graphics cards 

• Supports a wide range of video resolutions, including 4K and even 8K 

• Virtual reality (VR) 

• Augmented reality (AR) 

 
By watching the current situation, DisplayPort is likely to become even more important in the area of digital display and high-quality multimedia experiences as it continues to evolve. 

VGA Connector

 

VGA (Video Graphics Array) is an analog display interface standard that was first introduced by IBM in 1987. It provides a standardized interface for connecting computer monitors and displays, and quickly became a popular standard for video output in the computer industry.  

 

Applications: 

 

• Desktop computers 

• Laptops 

• Projectors 

• Televisions 

  

Although VGA is no longer widely used today, it played an important role in the development of modern display technology and paved the way for the digital display standards now in use.
