13733248 - ESAB AN3057-16 Connector Strain Relief Clamp

Technical Overview of the ESAB AN3057-16 Cable Clamp

The ESAB AN3057-16 Cable Clamp is a critical component designed for the assembly and maintenance of industrial circular connectors. Adhering to the widely recognized AN3057 standard, this accessory serves as a primary strain relief mechanism for multi-pin connectors used in heavy machinery, welding power sources, and industrial automation equipment. By securing the cable jacket firmly at the rear of the connector shell, the clamp transfers mechanical stress away from the delicate solder or crimp terminations inside the connector body. This isolation is vital for maintaining signal integrity and power transmission reliability in environments subject to vibration and physical movement.

Engineered for compatibility, the AN3057-16 size is specifically dimensioned to mate with standard connector shell sizes, typically ranging from size 24 to 28, depending on the specific connector series (such as MIL-DTL-5015). The unit is constructed from durable metal materials, often zinc die-cast or aluminum alloy, providing a robust housing that resists impact and corrosion. The design features a two-piece saddle clamp mechanism secured by screws, allowing for adjustable pressure on the cable jacket to accommodate slight variations in cable diameter while ensuring a non-slip grip.

In the context of electrical system design and MRO (Maintenance, Repair, and Operations), utilizing the correct cable clamp is a non-negotiable standard for safety and longevity. Without adequate strain relief, cables are prone to fatigue at the entry point, leading to short circuits, open circuits, or intermittent faults that can be difficult to diagnose. The ESAB AN3057-16 ensures that the assembly meets professional standards for mechanical endurance. It is an essential spare part for technicians servicing ESAB welding equipment or any industrial apparatus utilizing compatible circular connectors.

Installation is straightforward, requiring standard hand tools to tighten the clamping screws. The accessory not only secures the cable but also helps to center the wire bundle within the connector backshell, promoting an organized and professional termination. Whether for new cable assembly fabrication or field repair of damaged connections, this clamp provides the assurance of a secure, spec-compliant fit.
