Observation of Crimped Terminals Using X-Ray CT System

User Benefits

- 3D observation of the condition of electrical wires in the interior of crimped terminals is possible. - Measurement of the terminal shape and internal dimensions can provide feedback to the design and manufacturing processes. - Cycle testing of the same product is possible, enabling analysis of the product failure process.

Introduction

Methods for connecting electrical wiring to machinery and boards include direct connection, fixing with solder, and the use of terminals. Circular and Y-shaped terminals are available, and are widely used because they are easily connected and disconnected. Wires are attached to terminals by compressing part of the terminal around the wires in a process called crimping. Since the quality of crimping affects the stable operation and reliability of the machine concerned, inspection and analysis of the shape and strength of crimped terminals are frequently required. Although the external shape can be inspected visually or with a magnifying glass, X-ray CT (computed tomography) is effective for inspection and analysis of the interior of crimped terminals. This article introduces an example of nondestructive observation and analysis of the interior of terminals using a Shimadzu inspeXio SMX-225CT FPD HR Plus microfocus X-ray CT system.
