Solder Lugs and Rivet Lugs

Types of electrical lugs

A lug terminates a conductor so that it can be connected to a terminal, a circuit or a device. Lugs mainly differ in how they hold the conductor and how they are mounted:

• crimp lugs, squeezed onto the wire with a crimping tool: the ring and fork terminals found in switchboards;
• solder lugs (or solder tags), onto which the conductor is soldered;
• rivet lugs, riveted onto a terminal board or plate, with the conductor then soldered onto them.

We offer the last two families, the ones found on transformers, terminal boards and small electronic assemblies. Heavy cables that need crimped power lugs are outside our range.

Our tinned brass lugs

All our lugs are made of tinned brass and are RoHS compliant: the tin plating makes soldering easier and protects the metal from oxidation. They are sold individually.

• Solder terminals: N1384 and N2484.
• Rivet lugs: N34 (U profile), N795A (square base, 5.5 mm opening), N860 (flat, 15 x 6 mm), N869 (angled, 3.2 mm hole) and N891 (bent at 110°).

Each product page gives the key dimensions (height, width, thickness, hole diameter) so you can check the fit with your board or plate.

Soldering a lug

For these small lugs, a 50 to 100 W soldering iron and flux-cored solder wire are enough. Heat the lug and conductor together, feed the solder onto the joint, then let it cool without moving it. For the cable itself, see our H07RN-F flexible cable by the metre.
