Mobile WebSiteAccording to the function of the terminal, there are ordinary terminals, insurance terminals, test terminals, grounding terminals, double-layer terminals, double-layer conduction terminals, three-layer terminals, three-layer conduction terminals, one input and two output terminals, one input and three output terminals , Double-in and double-out terminals, switch terminals, overvoltage protection terminals, marking terminals, etc. According to the current classification, it is divided into ordinary terminals (small current terminals) and large current terminals (above 100A or 25MM lines).
Characteristic description of wiring terminal: each connection area is composed of insulating seat, U-shaped frame, nut, hexagon socket screw and upper and lower movable blocks. There are wiring holes between the opposite contact surfaces of the upper and lower movable blocks, and the hexagon socket screws pass through The nut rests on the upper movable block, and its purpose is to directly connect cables of different thicknesses to the high current terminal.
It is necessary to understand the function of the terminal. Some terminals have the function of grounding, and some terminals are double-layer conduction. For double-layer conduction terminals, the link piece can be omitted when paralleling, and attention must be paid to details.
It is necessary to understand the shape of the wiring terminal. Because the space of the power distribution cabinet is limited, it is necessary to calculate the internal space of the power distribution cabinet and what shape terminals can be placed to meet the design requirements.
You must understand the current of the terminal to be connected. Pay attention to the selection. The general terminal will be marked. This terminal supports the maximum current and maximum wire diameter, but sometimes the maximum wire diameter of the terminal is not suitable for on-site wiring. , You need to increase a level, such as 16mm wire, but after crimping the lug, the wire end will be bigger, you need to choose 25mm terminal, so you need to pay attention to the details in the daily selection.
