What are the common connectors and its standards?
There are many types of connectors in our daily life,such as USB,RJ 45,etc. These connectors all have unique characteristics and applications, and play a vital role in various industries and fields.
So this passage is going to talk about our daily life connectors and its standards.
- The RJ45 connector
Which is widely used for LAN, WAN and other network connections and is standardized by the Institute of Electrical and Electronics Engineers, is the first connector we will look at. This connector is 8-pins long, with each pin having a number and function. It can be used for different types of data transfer. We have RJ45 connectors from Cisco, D-Link and Huawei as well as other well-known manufacturers of network equipment.
- USB, or Universal Serial Bus
It is a widely-used interface standard to connect computers and external devices. USB connectors come in different models and specifications, including USB 2.0, USB 3,0 and others, with varying transmission rates and protocols. On the market we can find USB connectors from brands like Anker, Aukey and Romoss.
- HDMI connector
They are available in different versions and specifications, including HDMI 1.4 and HDMI 2.0. These support different refresh rates and resolutions. We have HDMI connectors from Samsung, Toshiba and LG.
There are many types of connectors besides the ones mentioned above. These include fiber optic connectors and RF connectors. These connectors all have unique characteristics and applications, and play a vital role in various industries and fields.
What is the standard for ?
There will be different connector standards between industries due to electrical properties, mechanical properties and environmental adaptability. This can limit the safety and stability of the connectors to provide performance. Here are some connector standards that you may encounter:
1)RJ45 standard: RJ45 is a standard network connector developed by the Institute of Electrical and Electronic Engineers. It has 8 pins with a number and function for each. This is used to satisfy the requirements of different data transmission types. RJ45 connectors must meet the electrical requirements for transmission rate, attenuation and crosstalk.
2)USB connector standard. The USB connector, developed by the USB Implementers Forum, is a widely-used interface standard. It has many models and specifications such as USB 3.0 and USB 2.0. Each model and specification has different transmission rates and protocols. USB connectors must meet the electrical requirements for transmission rates, currents, voltages, and more.
3)HDMI connectors come in different versions and specifications, including HDMI 1.4 and HDMI 2.0. They support different refresh rates and resolutions. HDMI connectors must meet electrical requirements, including transmission rate and signal quality.
The International Electrotechnical Commission has developed a standard for RF connectors. RF connectors must meet the required frequency range, impedance and voltage.
Mechanical performance standards: The mechanical properties of connectors include, among other things, the number of inserts and extracts, wear resistance and mechanical life. These standards are related to the reliability of the connector and its service life.
Connectors must also meet environmental adaptability requirements, including temperature range, humidity range and vibration resistance. These standards are related to the connectors' performance and life span in different environments.
Conclusion
There are many types of connectors besides the ones mentioned above. These include fiber optic connectors and RF connectors. They are used in many different fields and industries. Each connector has its own application scenarios and characteristics. To ensure stability and reliability, it is important to select connectors that are compatible with the current situation.
