There is provided wiring device for optical fiber capable of increasing the performance of construction work. A coveris disposed in an aperture formed at front surface of the plug receptacle main body, the upper end thereof is rotatably supported to the plug receptacle main body, and a receptacleis attached to the rear surface side of the cover. The receptaclehas a plug connection hole facing an outer surface side of a building at least at a used state and a plug connection portion into which a first optical-fiber plug being attached to the optical fiber cable wired to the inside of the building is inserted and connected, and optically connects the first optical fiber being connected to the plug connection portion and a second optical-fiber plug inserted from the outer surface side of the building through the plug connection hole. A notchfor inserting the first optical-fiber plug is formed at a sidewallof the plug receptacle main bodywhich is located in the inserting direction of the optical fiber plug inserted and connected to the plug connection portion.

Wiring device for optical fiber

A compact vehicle-mounted electrical outlet box offering a reliable plug blade detection function. The electrical outlet box is formed from synthetic resin rectangular casewhich includes bodyand coverA pair of electrical plug bladesandare inserted into plug blade insertion slotslocated on the front surface of casethrough which the plug blades contact two blade receiver partsThe forceful contact of plug bladesandrotate two pivot leverswhich convert the insertion force of plug bladesandto a directional force. Two return springsapply pressure to pivot leversin a direction opposite to that applied by the insertion of plug bladesandPrinted circuit blockwhich is comprised of circuit base plateto which each microswitchis installed, is housed within caseThe two pivot leversare located at the approximate mid-point of bodybetween the two mutually facing blade receiver parts.

There is provided wiring device for optical fiber capable of increasing the performance of connection work of an optical fiber cable without deteriorating a signal transmitting properties of the optical fiber cable. The wiring device comprise a plug receptacle main body which is mounted on a mounting opening opened in the outer surface of a building, a receptacle being provided to the plug receptacle main body and having a plug connection hole facing an outside of the plug receptacle main body, a winder including a winding body which has an outer circumferential surface of radius of curvature larger than the permitted minimum radius of curvature of an optical fiber cable wired to the inside of a building and connected to the receptacle and on which a core wire of the optical fiber cable is wound, and a retainer being provided on the plug receptacle main body to maintain the winder inner side of a building, in which the receptacle for optical fiber and the winder are arranged in parallel with each other in the front-back direction, and pressing pieces are formed integrally with the winder and the retainer for contacting the bent portion of the core wires to prevent the bent portion from being expanded.
