Because there are many types of electrical connectors and several key criteria need to be considered, it may be very difficult to choose the right connector. However, choosing the right connector is the most effective and reliable way to modularize, improve or reduce the size of the system, so that the system runs smoothly without frequent maintenance.
Consider the following Seven factors to choose the best connector for your application:
How many signals are there altogether?
What current, voltage and frequency do they carry?
Is your signal an a digital signal, analog signal, or a combination signal?
The combination of signals will affect the type of connector, pin arrangement and wiring. For example, high-frequency signals may need coaxial connection, while low-level analog signals may need shielding.
Some signal combinations cannot be included in the same connector. If high-voltage pins are involved, creepage distances and electrical clearances may need to be considered. If the current path is large, multiple pins and larger wires may be required. Depending on your unique situation and design requirements, you may also need customized solutions.
Rated current is the most important criterion for selecting cable connectors. It is a measure of the amount of current that can flow through the matching terminals, ideally expressed in amperes per circuit. The current should be adjusted or lowered according to the number of circuits in the given housing and the temperature rise of the adjacent terminals.
The size and weight of terminal connectors and cable connectors decrease with the decrease of available space. However, their ability to withstand and eliminate increased mating frequencies has been greatly improved. Therefore, depending on the circumstances and design requirements applicable to your project, you may need to find more options in electrical connectors.
Verify Recommended Operating Temperature Range
Most electrical connectors are affected by extreme conditions such as shock and vibration. Cable connectors and terminal connectors designed for extreme conditions and hazardous environments have special functions of withstanding extreme temperature and resisting shock and vibration.
Therefore, the wire termination connectors should be selected according to the position of the electrical connector, the distance from the heat source, the working temperature and the frequency of matching and canceling matching.
When purchasing wire cable connectors reliability is another important factor to consider. However, reliability is a complex concept , which depends on a few factors. Accurate numbers are difficult to determine, but some connectors come with an average failure time specification. This can be used as a guide for choosing the right electrical connector for any application.
6.Ensure That It Is Environmentally Sealed
Some environments require protective measures to prevent the invasion of flammable or flammable gases, liquids, dust or vapors. Electrical connector with environmental sealing option can effectively prevent accidental splash. Once you know the required security level, you can verify the IP level number in the IP code system and know if you are buying the correct connectors for electrical wire.
For safer workplaces, environmental sealing is a very important standard, especially in severe environments such as aviation, aerospace, medical, underwater and food.
Terminal materials and electroplating are usually the last factors to be considered, but because most electrical connectors are made of nylon plastic, they are flammable and have high flame resistance continuity. Available standard options include tin, select gold and lead for most applications. Base materials are usually made of brass or phosphorus bronze because they have excellent strength and current carrying capacity even when exposed to high ambient temperatures for a long time.
