Introduction of 5 main considerations when choosing a connector(图1)

  As electronic devices become more intelligent, the requirements of the connector market are getting higher and higher, so its design becomes more and more complicated. Regarding the importance of the role of connectors in electronic equipment, I have also talked about the world of plugging in the previous article. Without connectors, electronic equipment will become a stagnant pool and cannot operate. And when we choose the connector for the device, it is not a simple matter. There are many factors that need to be considered. The following plugging world will tell you about the 5 aspects that must be considered when choosing a connector.

  As electronic devices become more intelligent, the requirements of the connector market are getting higher and higher, so its design becomes more and more complicated. Regarding the importance of the role of connectors in electronic equipment, I have also talked about the world of plugging in the previous article. Without connectors, electronic equipment will become a stagnant pool and cannot operate.

  Five aspects must be considered when connecting a connector.

  1. Regarding the electrical parameters of the connector, will the connector pass a micro-amp signal or a lot of ampere power? Is it necessary to accommodate high-frequency or low-frequency digital or analog signals, or perhaps a combination of them? Is shielding required to protect signal integrity? The same connector that transmits electrical signals in any combination may also have to function as a host to obtain optical fiber information. For medical equipment, liquid or gas may need to pass through the same inlet, and a custom connector may be required.

  2. Regarding the constraints of the connector, should the connector be built on a desktop or a smart phone? The same combination of signal and power may have to be transmitted into or out of either device, but obviously, it will have to be compressed into much less space in the latter, and for wearable devices, the connector must also be compressed into In less space.

  3. Regarding the environmental conditions of the connector, will the connector be affected by vibration, shock or extreme temperature? Fortunately, the data sheets of most connector manufacturers will clarify the ability of their connectors to perform under such challenges, and attention to detail will protect against too few or too high specifications. There are also special connectors that can resist water, gas and even oil. Connector design specifications may specify the level of protection that must be provided to prevent moisture, dust, and other hazards. This level is usually described by an IP code, which is usually defined by the connector's specification sheet. Medical and food applications are environmentally challenging, as is the automotive sector, and aerospace and marine world equipment are even more challenging. There may be flammable gas or flammable gas and liquid in the hazardous area of level 1 and zone 2. This is another hazard that the connector must beware of.

  4. The issue of specific industry standards for connectors. The imposing of specific standards by specific industries on connectors is an issue that needs attention. For example, the FDA is deeply involved in medical equipment standards, the automotive industry has its SAE standards, and the military has proposed a large number of MIL standard.

  5. The reliability of the connector is an over-specified place, which is expensive, and over-specified can lead to recalls or worse. It usually only depends on how long the cable will mate and not mate with a connector. In some extremely challenging applications, it is difficult to obtain reliability because the connector may have to plug and unplug the cable few times during the life of the device, while in other benign applications, such as connection And Disconnect-Connect the micro USB connector of the mobile phone to the charging cable, which may need to be done several times a week.

  Don’t look at the small size of the connector and think it’s simple, but ignore its importance. Many electronic devices fail when they are in use, basically because of mechanical reasons. Therefore, it is recommended that you must be sure when choosing a connector. Considering comprehensively, there are a large number of commercial machinery connectors on the market for us to choose, and only through careful consideration can we choose the right connector for the device. The above is the content shared with you today, we must first get more connector knowledge.
