INFORMATION WIRING SYSTEM

摘要

PURPOSE:To provide the structure of a new plug socket capable of simplification of various circuit tests in an information wiring system. CONSTITUTION:Plug sockets 5 connected to respective information wiring 4 and a plug 7 capable of fitting into each plug socket 5 are provided, and a connecting state inside each plug socket 5 viewed from the information wiring 4 side is made so as to change according to respective states of the plug 7 being fitted or not fitted into each plug socket 5. Circuit tests for the information wiring 4 thus can be easily carried out by changing over from the fitting to the non-fitting of the plug 7 to each plug socket 5 and vice versa because the connecting state inside each plug socket 5 viewed from the information wiring 4 side is changed according to respective states of the plug 7 being fitted or not fitted into each plug socket 5 for the information wiring 4.
