Cable lugs (Battery Cable Lugs)
Cable lugs are the devices used for connecting cable and wire conductors in electrical installations and equipment. These are used when permanent, direct fastening methods are not feasible or necessary.
In general, lugs are fixed to cables and wires by inserting the conductor/s into the barrel (tube) of the device and then barrel is either crimped, soldered or welded onto the conductor for secure mechanical and electrical joint. The connection end of the lug is then fastened to connection point by means of a bolt, screw, or spring clip. Numerous sizes, configurations and material types are available to suit particular applications.
Connector end of lug is typically chosen for its compatibility to the terminal type. Fork or U-shaped lugs are used for screw terminals; closed-ring or O-type lugs are used for bolt-on applications; and pin lugs are used for press-on terminals. A cable lug also serves as a cable-size reducer, thereby allowing thick cables to be attached to a connector with a smaller diameter.
Cable connectors for electrical use are made of copper, aluminum connectors, brass, and plated to optimize voltage transfer and inhibit metal oxidation.
Cable lugs can be found on the wiring systems of automobiles, electrical boxes, panels, generators, transformers, many durable goods, and for all electrical lugs appliances.
Cable lugs help you to connect electricity properly with low voltage drop and less thermal heat generation to avoid accidenty and terminal burnout. It is very necessary to use right sqmm size of lug and proper crimping lugs has to be done with the right suggested crimping tool. Also to be noted is that you buy lugs of good make so that you get
