📝 Cable Butt Splice Joiner – Size: 50mm² (5 Pack)
These uninsulated cable butt splice joiners are designed for securely joining heavy-duty DC power cables in battery and inverter systems. Manufactured from high-conductivity tubular copper and finished with a protective tin plating, they provide a strong, corrosion-resistant connection for demanding 12v–48v applications.
Ideal for caravan, campervan, 4WD and off-grid electrical systems, these connectors are suited to both custom cable builds and professional wiring repairs.
⭐ Essential Benefits
• High-current performance – ideal for large DC cable connections
• Tubular copper body – excellent conductivity and mechanical strength
• Tin-plated finish – enhanced resistance to corrosion and oxidation
• Secure crimp design – delivers strong electrical and mechanical bonding
• Non Insulated – suitable for use with heat shrink if required
⚙️ Functionality
Each joiner requires crimping on both ends using a suitable heavy-duty crimping tool. Once crimped, the connector forms a low-resistance, high-strength join suitable for battery interconnects, inverter feeds and main power distribution wiring.
Designed for reliability in high-load systems where consistent performance is critical.
