This hammer-free copper cable lug eliminates the need for traditional hydraulic crimping tools; instead, it utilizes a dual-screw fastening mechanism, allowing for installation with just a standard wrench. Crafted from thickened pure copper, it offers excellent conductivity, high current tolerance, and minimal heat generation. It is ideal for connecting heavy-gauge cables in applications such as mining farm operations, inverters, photovoltaic systems, and heavy machinery, offering simple installation and easy maintenance or disassembly.
1. Hex-socket fastening bolts provide strong clamping force, ensuring the connection remains secure even in high-vibration environments.
2. Thickened pure copper body features low electrical resistance and minimal temperature rise under high current loads; it is highly resistant to oxidation and offers superior load-bearing capacity.
3. Designed with a ring-style mounting hole for direct attachment to equipment terminals; the flat contact surface ensures a secure, stable connection.
4. Available in three sizes (large, medium, small) covering a cable range of 10–70 mm², meeting diverse requirements for energy storage systems, equipment power cables, and more.
5. Dual-bolt locking structure allows for quick on-site installation: simply insert the stripped cable into the terminal block and tighten the screws to secure it without requiring hydraulic crimping tools. It also facilitates easy disassembly and inspection later on.
1. Modification of mining farm equipment cabling
2. Main line connections for energy storage systems, inverters, and lithium battery packs
3. Photovoltaic DC cabling and heavy-gauge wire transitions in power distribution cabinets
4. Cable terminal modifications for generators and high-power equipment
Model | Material | Plate Thickness | Wire Clamping Range | Hole Inner Diameter | External Dimensions |
Small | Pure copper | 1.2mm | 302–702 | 10mm | 35x45mm |
Medium | Pure copper | 1.5mm | 102–352 | 9mm | 47x14x19mm |
Large | Pure copper | 2mm | 102–502 | 9mm | 55x17x21mm |
1. Strip the cable insulation to expose sufficient copper strands, ensuring the strands remain bundled and do not fray.
2. Loosen the fastening screws at both ends and fully insert the copper conductor into the terminal's barrel.
3. Use a wrench to tighten the two bolts sequentially, clamping the copper wire securely to ensure a firm connection.
4. Align the terminal's ring lug with the equipment's connection stud and tighten the securing nut.
1. Clean the copper strands before connection to remove impurities or oxidation that could impair conductivity.
2. Ensure bolts are fully tightened to prevent overheating caused by a loose or poor connection.
3. After installation, it is recommended to insulate any exposed copper sections using heat-shrink tubing.
4. Select the terminal based strictly on the cable's cross-sectional area (gauge); do not use undersized terminals for loads exceeding their rated capacity.
