<p>PURPOSE: To avoid misconnections by a method wherein only one of a plurality of module-type units which are combined with each other horizontally or vertically has a contact strip piece with a lead-inlet, and a functional component insertion piece and the other units have the functional component insertion pieces only. CONSTITUTION: Insertion pieces 4 for plug-in sockets of functional components such as printed wiring boards mounted with electrical and electronic components, paging devices, signal devices, etc., and for current breakers, etc., are provided in a plurality of module-type socket parts 1. Only one of the socket parts 1 has a cable introducing inlet 3 and a contact terminal strip piece 2 in addition to the functional component insertion pieces 4. Rigid plug-in parts 7 are provided on the contact terminal strip pieces 2 to connect to connectors 9 and the functional component insertion pieces 4. The connectors 9 and the functional component insertion pieces 4 are also connected to each other with the rigid plug-in parts 7. The socket components 1 are covered with covering caps 5 for protection, arranged horizontally and piled vertically. With this constitution, the assembly can be simplified and the misconnection can be avoided.</p> |
