Terminals are components connected to the external conductor of a battery. In electrical engineering, terminal multi finger wiring terminal, also called wiring terminal, is divided into single hole, double hole, socket, hook, etc., from material, copper silver plating, copper zinc plating, copper, aluminum, iron and so on. Their function is mainly to transmit electrical signals or electrical conduction.
In the face of the terminal selection you would first think of the line current, size, direction, wiring applications, wiring, wire diameter and the current current is line diameter and nominal, in the general direction of the front and side connection with the design of the main outlet is capable of convenient operations and technical personnel, so as to improve the efficiency of application of work. The terminal has a wide application range, such as terminal procurement for welding in PCB circuit board, then you will not be able to choose the terminal wiring on the rail above the general basic structure of docking, suspension, etc. general fixed terminals by the insulating base, an insulating barrier, a line composition, consisting of an insulating base.
Under different environmental conditions, the correct selection and use of wiring terminals is a certain regularity. Although there is no definite use system in the industry, the specific terminals can be chosen according to the specific environment and conditions. Among them, four basic principles can be used as a reference.
First of all you have to know what you want to look like the terminal in the terminal before, according to the terminal function classification, common terminal, terminal insurance, test terminal, grounding terminal, double terminal, double conduction terminals, three terminals, three layers of conductive terminals, an inlet and outlet terminal, a three terminal and double inlet and outlet terminal, switch terminals, overvoltage protection terminals, terminals and other markers. According to the current classification, divided into ordinary terminals (small current terminals), high current terminals (above 100A or above the 25MM line). Classification by appearance. It can be divided into rail type terminal, fixed terminal, circuit board terminal (PCB terminal) and so on.
The second is to consider the size of the connection terminals, for different size and scope, his connection is not the same, when using the terminal normally, select the connection wire diameter slightly larger than the actual range is relatively good. Because the market standard is chaotic, and if the wire diameter aperture wiring of the same size, then it may be because the terminal market is not in conformity with the standards of production due to connection is smaller and can't line into the line in the box.
Again is the current rail terminal for this already exist in the market products for decades, in the industry for the current is required, different models have the current specification and products must meet the standards or exceed the standard.
Finally, the size of the space used. Different terminals can be chosen for different space sizes. For example, in a narrow space, you can choose double layer terminals, or three layer terminals.
