What are copper terminals

Copper lugs:

Ever wondered what is the silver sparkling metal at the end of your cables or between your wires?
Well, Its a Copper Lug. Copper lugs (cable lugs) are devices used for connecting cables to electrical appliances, other cables, surfaces, or mechanisms. The clamps that connect wires to an automotive battery are a common example of a copper lugs, as are the ends of battery jumper cables. Designed to be easily installed and removed for repairs or maintenance, copper lugs are generally used when permanent, direct-fastening methods are not feasible or necessary.

Copper Lugs  may be provided with safety covering to avoid shocks or protective covering to avoid damage to the copper lugs, cables, connectors and prevent short-circuit.

Copper lugs are ideal for large gauge applications for power draw or grounding. Each copper lug can be either crimped or soldered to wire. The copper lug features a burr-free appearance for an aesthetically pleasing finish

One end of the copper lug accommodates the cable using a soldering, welding or crimping method, depending on the type of lug. The other end of the copper lug is fastened to a matching terminal or connection point using a bolt, screw or spring clip.
