<p>A cylindrical part having an axial slit and called a split alignment sleeve (2) is used in an optical fiber connector for connecting optical fibers to each other. The split alignment sleeve (2) is made of a ceramic material, and the characteristics of the optical fiber connector can be largely improved. Since the split ceramic alignment sleeve (2), however, is brittle, its mechanical strength may be degraded, and the sleeve may be damaged during use for a long period of time. In order to proof the strength reliability of the split ceramic alignment sleeve (2), a predetermined stress is applied to it during a manufacturing inspection to perform a proof test having a criterion for ensuring not to damage the sleeve. The present invention provides an easy, low-cost test method and an apparatus therefor. More specifically, since a test load is applied from the inner circumferential surface (15a) of the split ceramic alignment sleeve, the shape, structure, and assembly of the loading part of a test apparatus are disclosed, and a proof test method of the split ceramic alignment sleeve by using the test apparatus is also disclosed. <IMAGE></p> |
