Wiring Work And Requirements Of Cold-pressed Terminals
Cable Lugs is also called insulated terminal. In the technical field, the use and operation of cold-pressed terminals must be carried out in accordance with certain standards. For example, the main tools used in wiring operations are: wire clamps or diagonal clamps, wire clamps, scrubbing clamps, screwdrivers, electric soldering irons, hot fans (blowing heat shrink tubes), needle-nosed pliers, wrenches, tweezers, and tape measures. The clamps have pre-insulated end clamps, tube end clamps, and exposed end clamps. Screwdriver hair moves, electrical, and pneumatic; according to the shape, they are divided into crosses and one word. There are plum blossoms, holes, and bushes in the wrench.
At the same time, the main contents of the material research to be considered when wiring between cold-pressed terminals are: wires, wire troughs, wiring engineering ends (cold-pressed terminals), soldering tin wires, heat shrink tubing, using transparent plastic tubing, and numbered tubing. The wiring should be reasonable and the weak current should be separated.
When wiring, it is necessary to remind everyone to pay more attention to the selection of cold-end wiring. If there is no requirement, the cross-sectional area of the wire must be at least 0.5mm2 (safety guarantee). Insulated wires are selected without interference (to reduce costs); shielded dual-core wires are used as much as possible for signal wires. Tinned copper conductors are used in humid environments or devices marked with "TH". The wires are generally black. The DC power line is connected with brown and blue subtraction, the neutral line is light blue, and the yellow-green ground line (dark color).
Do you know what specific requirements are there for the quality of cold-pressed terminals? Generally, the cold-pressed group should be made of copper and treated with tin, tin, lead, silver or nickel. There should be no seams at the end of the pipe. Wire pressing note: the bald indentation must be located in the center of the pressure parameter, pressed on the pipe gap, and cannot be bent after joining.
In addition to these effects, when the wire core is inserted into the end of the cold-pressed terminal, no single-wire problem is allowed, and it is not allowed to be exposed again through the wired core. The inspection requirement is to press the wire, which cannot be solved with normal force.
