16DA5082 - Tweco 97-3057 Cable Clamp for MPC Connectors

Technical Overview of the Tweco 97-3057 Cable Clamp

The Tweco 97-3057 (SKU: 16DA5082) is a specialized cable clamp designed for use within the Tweco Mechanical Power Connector (MPC) system. In high-amperage welding applications, the integrity of the electrical connection is paramount. However, the physical connection between the heavy-gauge welding cable and the connector housing is equally critical. This cable clamp serves as the primary strain relief mechanism for the assembly.

Constructed from durable steel, the 97-3057 clamp is engineered to grip the cable jacket securely when tightened within the connector shell. By anchoring the cable jacket, the clamp transfers mechanical tensile loads—such as dragging, pulling, or hanging the cable—away from the stripped copper strands and the electrical set-screw or crimp junction. This isolation is vital for preventing gradual loosening of the electrical contact, which can lead to increased resistance, overheating, and eventual failure of the connector.

This component is an OEM replacement part, ensuring exact dimensional compatibility with Tweco MPC housings. Using non-standard or makeshift clamping solutions in high-current connectors can compromise safety and durability. The 97-3057 ensures that the cable remains concentrically aligned and firmly retained, maintaining the IP rating and mechanical robustness of the connection system. It is suitable for industrial maintenance, repair, and operations (MRO) where reliable welding power transmission is required.

Proper installation of the cable clamp involves positioning it over the cable jacket at the specified distance from the stripped conductor, ensuring that when the connector halves are assembled, the clamp engages fully without crushing the internal insulation layers. This part is essential for extending the service life of welding leads in harsh shop environments.
