The Selection Method Of Terminal Blocks Should Be Considered From The Following Aspects

When it comes to the plastic insulating materials and conductive parts of the terminal, to a great extent, they will directly affect the quality of the terminal itself. They determine the insulation performance and conductivity of the terminal respectively. Any terminal failure will certainly bring great danger to the owner's personal and property. In this regard, it is also very profound for the painful lessons at home and abroad.

When purchasing terminal blocks, the first thing is to pay attention to the appearance. A good terminal should have good workmanship, which can not be passed by visual inspection. Basically, there is no need to waste time to conduct electrical test. In view of this, what kind of terminal is considered to be good workmanship? On this issue, the industry generally believes that the plastic parts of qualified terminal blocks should not be deformed as a whole, and the surface is relatively flat without scratches, and there will be no burr on the edges and corners, and the wall thickness must be uniform.

In the purchase of terminal blocks, it is also necessary to look at the material. First of all, it is necessary to pay attention to the plastic parts. It is inevitable that they will have better flame retardant performance, that is, the flame retardant grade of UL94V-0. The simple test method is to indicate that the fire is ignited and the plastic parts are extinguished after leaving the open fire, which means that the terminal block has good flame retardant performance.

In the purchase of terminal blocks, it is also necessary to pay attention to its plug-in force. More importantly, the fit between the plug and the needle base is relatively high, and there is no phenomenon of too high or too low insertion and extraction force.

When purchasing terminals, there is a certain gap between domestic brands and foreign brands in terms of technology, manufacturing, industrial design, or financial strength. In conclusion, if there is no reliable terminal, the safety of the owner's life and property can not be better protected.
