The basic knowledge of the classification and selection of terminal specifications and models

The classification of terminal blocks can be divided in several ways. At present, there are three common methods. According to the terminal raw materials, such as copper terminals, according to the terminal functions, such as printed circuit board terminals, the last one is the more familiar classification by the market, according to the connection form of terminals, mainly including the following categories:

一 Screw Type Terminal Block: a terminal block that uses a bolt to wind or fix a ring type terminal and then fix it with a nut.

二 Plug In Terminal

三 Screw Free Spring Type Terminal Block

四 American Standard Barrier Terminal

五 Through Terminal

Terminal selection
The selection of wiring terminal is nothing more than wire diameter, current, wiring direction, application occasions, wiring mode and other wire diameter and current, which is not mentioned here, that is, the size of wire diameter and rated current. The wiring direction generally has the front wiring and the side outgoing line, mainly for the convenience of the technical personnel to operate conveniently, thus improves the work efficiency application situation, this is a very common question, the wiring terminal application scope is quite wide, for example, you choose the wiring terminal to weld on the PCB board, then you are not likely to choose the wiring terminal used on the guide rail Generally, the basic composition of general terminal blocks with docking, hanging, fixing and other modes is composed of insulation base, insulation partition, wire parts, and insulation base. In the face of terminal selection
