Soldering ring terminal Ergom B311, 6/5 mm, pack of 100 (E14KI-03010100300)

Ergom B311 soldering ring terminals, size 6/5 mm, pack of 100 are ring-type cable terminals designed to provide a secure electrical connection between wire conductors and studs or bolts. Manufactured for reliable mechanical and electrical contact, these terminals combine a crimp barrel for wire insertion with a solder cup to ensure good conductivity and long-term stability in installations where vibration or movement may be present. The pack of 100 provides a convenient supply for maintenance, repair, or small production runs.

Advantages

These Ergom B311 ring terminals offer a dual-connection method — crimping and soldering — which improves both mechanical strength and electrical continuity. The ring design ensures a stable connection to screw or bolt terminals and reduces the risk of wire pull-out. Supplied in a pack of 100, they are suitable for repeated use across multiple assembly or repair tasks and help maintain consistent terminal quality across connections.

Suitable for

• Electrical installations and junction boards
• Automotive wiring and vehicle electrical repairs
• Control panels and industrial equipment connections
• Home appliance repair and DIY electrical projects

Key specifications

• Terminal type: ring terminal with solder cup
• Ring inner diameter: 6 mm (suitable for studs/bolts of corresponding size)
• Wire barrel diameter: 5 mm suitable for appropriate conductor cross-sections
• Material: conductive metal suitable for soldering (metal plating may be present)
• Pack quantity: 100 pieces

How to use

Strip the insulation from the wire to the appropriate length for the barrel. Insert the conductor into the terminal barrel and perform a crimp using a suitable crimping tool to secure the wire mechanically. Apply solder to the solder cup to form a durable electrical connection; ensure proper heating and solder flow to fully wet the conductor and terminal without overheating surrounding insulation. Place the ring over the stud or bolt and fasten with the appropriate nut to complete the connection.

Usage recommendations

Use the correct conductor size and a compatible crimping tool to achieve a reliable mechanical crimp before soldering. Avoid excessive heat that could damage wire insulation; use flux and the proper solder for electrical connections. For applications exposed to moisture or corrosive environments, consider additional protective measures such as heat-shrink tubing or corrosion-resistant coatings.
