Description

  The present invention relates to an outlet attached to a wall surface for connecting various electric devices in a room to exchange electric and optical signals.

Conventional outlets such as modular jacks for LAN, telephone lines, TV signal lines, etc. are made of a wall surface as disclosed in, for example, Patent Document 1 in order to make this a composite type that enables optical signal exchange. Is installed by replacing the plate frame and face plate of the existing outlet box arranged in the above with the outlet plate in which the optical fiber is accommodated. That is, at least one of the outlet box and the mounting frame is used as it is, and an opening for mounting is newly provided on the wall surface by attaching the optical fiber storage plate and the cover plate constituting the outlet plate. There is a technology that can install an outlet having an optical fiber connection function without performing incidental work such as repair or repair.

  However, in the past, a new component has been created by removing some or all of these components, such as replacing the plate frame and face plate of the existing outlet box mounted on the wall with an outlet plate that houses the optical fiber. Therefore, when changing from the existing outlet to the composite outlet described above, there is a problem that the work is troublesome and the number of parts is increased, so that the cost is also increased.

  Therefore, the present invention has been devised in view of the existing circumstances as described above, and without disposing main components and replacing them with new components when arranging a composite outlet. Therefore, it is possible to use the existing outlet member mounted on the wall surface with almost no replacement, thereby providing an outlet that is easy to dispose and low in cost without increasing the number of parts. The purpose is to do.

  In order to solve the above-described problems, the present invention includes a cover body that can be attached to the front surface of an existing outlet disposed on a wall surface, and the cover body includes an optical adapter for connecting an optical connector on the inside. And a connection port for electrical connection is provided on the front side, and a connection port for optical connector connection for optical connection via the optical adapter is provided on the lower side. It is characterized by.

  Further, the cover body is fixed to the front surface of the decorative plate via a fixture fixed to a mounting frame which is a component of an existing outlet.

  According to the present invention, when installing the composite outlet, the main component is not removed and replaced with a new component, and therefore, the existing outlet member attached to the wall surface is almost replaced. Therefore, the arrangement work is simplified, and the number of parts is not increased and the cost can be reduced.

The best mode for carrying out the present invention will be described below with reference to the drawings.
As shown in FIG. 1, a general outlet used for electrical connection is mounted and fixed to an outlet box P, for example, a telephone module jack M, installed inside the wall surface through a central opening of the wall surface B. In this state, the mounting frame 1 fixed with screws 12 to the screw holes R on the front opening 10 side of the outlet box P, the holder H screwed to the mounting frame 1, and the decorative plate fitted into the holder H from the front K each.

  Further, as shown in FIGS. 1 and 3, the mounting frame 1 is formed with a substantially rectangular opening 2 at an upper and lower position via the telephone module jack M, and through this opening 2. The fixing tool 3 is fixed to the mounting frame 1, and a cover body 4 to be described later is attached via the fixing tool 3.

  That is, before attaching the mounting frame 1 to the front opening 10 of the outlet box P, a substantially rectangular piece-shaped fixture 3 as shown in FIG. 6 is fitted into each of the openings 2 from the rear side. A pair of stepped flange-shaped locking portions 3a projecting from both ends of the fixing device 3 on the rear surface side are locked by the stepped locking portions 2a of the opening 2 so as not to be pulled out to the front side. The attachment frame 1 is attached to the front opening 10 of the outlet box P. At this time, from the central opening 11 of the decorative plate K fitted into the holder H from the front surface, the front surface portions of the fixtures 3 located above and below are exposed.

  In addition to the telephone module jack M, a LAN modular jack, an antenna terminal, etc. (all not shown) can be attached and fixed to the mounting frame 1.

  As shown in FIGS. 3 and 4, the composite outlet according to the present invention has the holder H for the mounting frame 1 and the decorative plate K attached to the existing outlet disposed on the wall surface B. In this state, the cover body 4 capable of disposing the optical adapter D for connecting the optical connector C shown in FIG.

  That is, as shown in FIG. 2 and FIG. 5, the cover body 4 is formed in a box-shaped frame shape having a rear opening, and is provided at the upper and lower positions of the recessed portion 5 that is recessed inward at the front center. A pair of screw holes 6 matching 3b (shown in FIGS. 1 and 3) is formed, and a part of the annular surplus space S (shown in FIG. 3) between the recessed portion 5 and the side wall of the cover body 4 An optical adapter D for connecting the optical connector C is inserted vertically in the (back side).

  A connection port 7 for electrical connection is provided in the center of the recessed portion 5 of the cover body 4, and an optical connection via the optical adapter D is provided on the lower side corresponding to the disposed optical adapter D. The connection port 8 for connecting the optical connector C for connection is provided downward, and the other optical connector E is connected to the upper part of the optical adapter D.

Next, an example of assembly and use of the best mode configured as described above will be described.
In order to form a composite outlet, when attaching the cover body 4 to an existing outlet, as shown in FIG. 1, first, the mounting frame 1, the holder H, the decorative plate K, and the screw 12 attached to the existing outlet are attached. Remove it.

  Then, an optical fiber cable L (shown in FIGS. 2 and 3) drawn from the outlet box P to the front is connected to the optical connector E, and the optical connector E is connected to the optical adapter D for connecting the optical connector C. Connecting. The optical adapter D is inserted and disposed vertically in a part (back side) of the annular surplus space S of the cover body 4.

  At this time, as shown in FIG. 3, the surplus cable portion of the optical fiber cable L is wound and accommodated along the annular surplus space S of the cover body 4.

  Next, after attaching the fixture 3 to the opening 2 of the mounting frame 1, the mounting frame 1 is fitted into the front opening 10 of the outlet box P on the wall surface B. Thereafter, the screw 12 is screwed into the screw hole R of the outlet box P through the screw hole of the mounting frame 1. In addition, the holder H and the decorative plate K are fixed to the mounting frame 1 with screws.

  Next, after covering this cover body 4 so as to cover the entire central opening 11 of the decorative plate K, screws 9 are screwed and fixed from the screw holes 6 of the cover body 4 to the screw holes 3 b of the fixture 3. Thus, the composite outlet can be formed simply by screwing and fixing the cover body 4 without substantially changing the configuration of the existing outlet.

It is a disassembled perspective view which shows the whole structure of the outlet in the best form for implementing this invention. It is a front view of an outlet similarly. In FIG. 2, it is XX sectional drawing. It is a perspective view of an outlet similarly. It is a perspective view of a cover body similarly. It is a perspective view of a fixture similarly.
