In the face of the insulation terminal selection you will first think of the wire diameter, and direction of current, connection, the application occasion and connection mode, wire diameter and current is the wire diameter and the rated current, moreover wiring direction generally have a positive and side for this design is mainly can facilitate the operation of the technical personnel, and improve the efficiency of the job application.Insulation terminal has a wide scope of application, such as purchasing the insulation of the terminal is to welding on the PCB circuit board, then you won't be able to choose the guide rails above the insulation of the terminal connection mode, generally have docking, dangling, fixed, including basic composition of general insulation terminal consists of insulating base, insulation plate, wire, insulation base etc.
Under different environmental conditions, the choice of the right to use the insulation terminal has certain regularity.Although there is no specified use system in the industry, but can be used according to the specific environment and conditions of use to select a specific terminal.There are four basic principles can be used as a reference.
First in the terminal before you have to know what you want to terminal, according to the terminal has the function of the classification, common terminal, insurance, terminal testing terminal and earthing terminal, double terminal, double conduction terminals, terminal, three layer three layers of conduction terminals, one in double out terminals, one in three out of the terminal, double in double out terminals, terminals, breaker terminal over-voltage protection, tag terminals, etc.According to the current classification, divided into, common terminal (low current terminal), large current terminal (or 25 mm line more than 100 a above).According to the classification.Can be divided into cellular terminal Fixed terminal PCB terminals (PCB terminal), etc.   
Second is to consider the size of the connection, for different insulation terminal, his size and scope of wiring is different, usually use terminals, to choose connection wire diameter larger than the actual is better.Because the current market standard is chaotic, if choose connection aperture of the same size and wire diameter, then likely because the market does not conform to the standard production of terminal wiring smaller and cannot be inserted the line to line pressing box.
Is current, again for the guide rail type terminal that has existed for decades of products in the market, the industry is has a regulation for a electric current, different models have a certain current specifications, product must meet the standards or more than the standard.
Finally is the use of space.For different size can choose different terminals.Such as in the narrow space can choose double insulation terminal, or three layers of insulation terminals.
In addition the choose and buy insulation terminal should also pay attention to the points:
A, appearance
Good insulation terminal should first have a good work, not through visual basically don't have to waste time for electrical test again.So, what kind of insulation terminal is good you work?Industry is generally believed that the insulation terminal of qualified parts should be overall intangible, smooth surface, no scratches, edge horn without burr, uniform wall thickness;More importantly, the plug and needle fit degree is high, not too high and too low insertion force phenomenon.
Second, the material
Parts, first is to have good flame retardancy, namely UL94V - 0 flame retardant grade;Simple test method that is flame lit, plastic parts leave the flame extinguished as the insulation terminal has good flame retardant performance;Then the pressure box, many clients often said that the insulation of the terminal copper or not is actually refers to a wire frame.Visually identify carefully, copper box than the simple sense of iron ore has more angular, of course, the safest way is open to take out the plastic wire frame for further testing, cannot listen to sales staff side of the story.
Three, torque
90% of poor contact Insulated Terminals on the market for screw torque can not meet the requirements, therefore, insulated terminal screw torque is particularly important.As a result, better to use screwdriver can feel the screw tight wire.
