UL 486A-B mechanical strength test apparatus

Product Details

CKINSTO UL 486A-B Mechanical Strength Test Apparatus   The CKINSTO UL 486A-B Mechanical Strength Test Apparatus is a state-of-the-art, multi-functional system designed to rigorously evaluate the mechanical and electrical integrity of wire connectors and soldering lugs for use with copper and/or aluminum conductors. Engineered in strict compliance with the UL 486A-B standard, this apparatus is an indispensable tool for manufacturers, certification bodies, and test laboratories seeking to ensure product safety, reliability, and standards compliance. This apparatus performs the two most critical mechanical tests defined by the standard: the Pull-Out Force Test and the Secureness Test. Key Features & Functions: 1. Pull-Out Force Test (Tensile Strength) Function: Measures the force required to pull a conductor out of its connector or terminal. This test is crucial for verifying the crimp or screw connection's holding strength. Precision Measurement: Features a high-accuracy load cell to measure the pull-out force in real-time. Controlled Rate: The system applies a controlled tensile force at a precise rate to ensure consistent and repeatable test results, as per UL requirements. Wide Range: Accommodates a broad range of conductor sizes and connector types, with interchangeable clamping jaws and fixtures. 2. Secureness Test (Flexing & Bending Endurance) Function: Simulates real-world mechanical stress by subjecting the connected conductor to a specified number of flexing or bending cycles. This test assesses the connection's ability to remain secure under repeated movement. Automated Flexing: The apparatus features a programmable, motorized mechanism that flexes the conductor at a set angle and a specific rate (e.g., 10 RPM) for the required number of cycles. Continuity Monitoring: An integrated electrical circuit continuously monitors the connection. The test automatically stops if the connection fails (i.e., opens the circuit), and the number of cycles at failure is recorded, providing precise data. Adjustable Weights: Includes a set of calibrated weights to apply the specified tensile load on the conductor during the flexing test, as per the standard's tables. General Specifications & Design: Standards Compliance: Fully compliant with UL 486A-B and other relevant standards such as IEC 60947-7-1 (for terminal blocks). Robust Construction: The main frame is built from heavy-duty, powder-coated mild steel, ensuring stability and long-term durability in a demanding industrial environment. Intuitive HMI Control: A user-friendly HMI touchscreen allows for easy setup of test parameters, including conductor size, pull force, number of cycles, and test speed. Real-time Data Display: Digital displays for force, cycle count, and test status provide instant feedback. Safety Features: Includes an emergency stop button, safety interlocks on the test fixtures, and over-force protection to ensure operator safety and prevent equipment damage. Versatile Fixtures: Comes with a comprehensive set of interchangeable jaws, bushings, and weights to test a wide variety of connectors, lugs, and conductor sizes.
