DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical outlet provided with an optical fiber connector.

[Prior art]

When building a LAN (local area network), etc., the host computer and each terminal are connected by optical fibers. At this time, optical fibers are laid on the walls and floors of the building, and optical fiber connectors are installed on the walls and the like. Is provided, and the other end of the optical fiber having one end connected to each terminal is connected to the optical outlet.

[Problems to be solved by the invention]

However, conventional optical outlets are formed exclusively for optical fibers, and have no common parts with those widely used as commercial power wiring devices.
In addition to the high cost, even those who use it must take the power of the terminal from the commercial power outlet and connect the communication optical fiber to the separately provided optical outlet, These lines are intersected, making it inconvenient. The present invention has been made in view of such a point,
The purpose is to easily and surely connect optical fibers, and to reduce the cost and increase the number of common parts with those widely used as commercial power wiring equipment. To provide an outlet.

A body having a portion, a cap detachably attached to the back surface of the body, and a ferrule and a sleeve disposed in each of the protrusions, which are attached to the end of an optical fiber introduced into the body through the cap and whose distal end faces are open The cap has substantially the same size as the rear surface of the body, and is characterized in that a means for pressing the ferrule against the sleeve is housed in the cap. A connector made of modules and having the size of two basic modules, and a common insulation for commercial power wiring equipment A body having a mounting frame, the connector having a pair of projections in a plurality of recesses formed on a front surface thereof and having engagement portions with the mounting frame on both side surfaces, and a back surface of the body. And a ferrule and a sleeve which are attached to the end of the optical fiber that is introduced into the body through the cap and are disposed in each of the protrusions whose tip end surfaces are open, and the cap is provided on the body. It has substantially the same size as the rear surface, and is characterized in that a means for pressing the ferrule against the sleeve is housed in the cap. <Operation> According to the present invention, a commercial power supply wiring device can be used as a mounting frame, and a commercial power outlet and the like can be simultaneously mounted on the mounting frame. <Embodiment> Figs. 1 and 2 show an embodiment, in which a connector 1 has a body 2 having a pair of projections 21, 21 in a recess 20 on the front surface, and a back surface of the body 2. And a cap 3 having substantially the same size as that of the body 2 and a cap 3 detachably attached to the back of the body 2.
The body 2 of both, which is formed as a synthetic resin molded product, has locking projections 22,
Are projected, and fitting projections 23 are respectively projected near the rear portions of both side surfaces. A positioning projection 24 protrudes from the rear end of the body 2. In the figure, reference numeral 29 denotes an engagement concave portion used for mounting on a metal mounting frame. The cap 3 has a slit 30 through which the optical fiber 5 passes.
And a pair of locking pieces 31, 31 protruding forward from both side ends thereof. The locking pieces 31 are engaged with the fitting protrusions 23 of the body 2. Mating hole
33 is provided, and the positioning projection 24 is provided with a slit 30.
, The cap 3 is positioned with respect to the body 2, and the cap 3 is attached to the body 2 by the fitting projection 23 engaging with the fitting hole 33. Both of the projections 21 on the body 2 are hollow, both having an open front end surface and an interior opening on the back, and are connected to the end of the optical fiber 5 introduced into the body 2 through the cap 3. Ferrule 51 to be fixed,
A sleeve 52 to be put on the ferrule 51 is housed inside. In the figure, 53 is a ferrule 51 and a sleeve 52
Spring for pressing against Here, the connector 1 configured as described above is used.
Is made of the same modules as those widely used in indoor wiring devices such as wall outlets and switches of commercial power supplies, and is formed to have the size of one basic module. When it is installed on a wall or the like for use as a power supply, it is mounted on the same insulating type mounting frame 4 as that used in an indoor wiring device of a commercial power supply. That is, the connector 1 is attached to any one of the engaging portions 40 of the mounting frame 4 having a rectangular shape provided with openings corresponding to three basic modules and having three pairs of engaging portions 40 on both side pieces. The connector 1 is mounted on the mounting frame 4 by engaging the locking projections 22 of the mounting frame 4.
Is fixed to a wall or the like, and a cover (not shown) is attached thereto to serve as an optical outlet. The other end of the optical fiber, one end of which is connected to the terminal, has a protrusion.
The optical fiber 5 in the sleeve 52 through the tip opening 21
The connection is made by facing the tip surface of the ferrule 51. While the mounting frame 4 corresponds to three basic modules, the connector 1 is only as large as one basic module, and the mounting frame 4 has one connector and one basic module. It is possible to attach two wiring devices of a size and one wiring device of a size corresponding to two basic modules. Power outlets and DC power outlets can be connected in series. 3 and 4 show an example in which the connector 1 in the above embodiment has a door 25. FIG. The door 25 here has shafts 26 protruding from both side edges at the lower end thereof, and these shafts 26 are slidably engaged with grooves 27 formed on the opposite inner wall surfaces of the recess 20 of the body 2, At the front end of 27, it is engaged so as to be freely rotatable. When not in use, the protruding portion 21 is covered as shown in FIG. 3 (a), and when in use, it is shown in FIGS. After turning, as shown in the figure, slide the door into the
25 can not be projected. In the embodiment shown in FIG. 5, the connector 1 is sized for two basic modules of a wiring device, and two recesses 20 each having a pair of protrusions 21 are formed on the front surface of the body 2. A total of four optical fibers 5 are connected. When a loopback is configured in the LAN, two double-core optical fibers 5 are required, but this can be dealt with. In this case, the mounting frame 4 side also has a commercial power outlet or the like. There is room to attach other wiring equipment.

As described above, according to the present invention, a connector made of a module common to that for a commercial power wiring device and having a size of one basic module is provided in the recess formed on the front surface. A body having a pair of projections and engaging portions with mounting frames on both sides, a cap detachably attached to the back of the body, and an optical fiber terminal introduced into the body through the cap. The cap has substantially the same size as the rear surface of the body, and means for pressing the ferrule against the sleeve is housed in the cap. Introduce the optical fiber into the body through the cap and insert the ferrule fixed to the end of the optical fiber. You can hold it while pressing it on the leave,
Optical fibers can be easily and reliably connected. In addition, a mounting frame for a commercial power supply wiring device can be used, so that components can be used in common, so that the cost is reduced and, in addition, the mounting frame can be used to mount three of the size of the basic module. The connector itself is only as large as one or two basic modules, so that it is possible to connect an outlet for commercial power supply, etc. It can be summarized as follows. And a connector with the size of two modules can handle the case where the LAN is configured by loopback.
