Structure of a fastener with illuminators

摘要

A fastener includes a main body (4), a light guide (5), and a threaded securing member (6). The light guide (5) is fit over the main body (4). The main body (4) with the light guide (5) thereon is fit into a mounting hole of a mounting plate and the threaded securing member (6) engages a threaded section of the main body (4), whereby a top retention portion of the main body (4) and the threaded securing member (6) together establish abutting engagement that securely fixes the main body (4) to the mounting hole (91). A light source unit (8) is arranged in the threaded securing member (6) and connected to a power source. Illuminators (81) are mounted on the light source unit (8) may give off light that is guided by the light guide (5) to emit through a light emission portion of the light guide (5). Thus, the light emission portion of the main body (4) may serve as a lighting ring for warning or indication purposes.
