Description

  The present invention relates to an information outlet to which a connection line for information communication such as an optical cable is connected.

  Conventionally, in order to perform information communication by connecting to a telephone line or a LAN, an information outlet is installed on a construction surface such as a wall surface. It is configured by attaching a wiring device including a modular jack for a line, a modular jack for a LAN, and the like.

By the way, in recent years, with the spread of optical communication, the demand for information outlets having an optical outlet for performing information communication using an optical fiber is expanding. As such information outlets for optical communication, rectangular Provided with a mounting frame that is attached to a construction surface such as a wall surface having an open window at the center, a decorative plate that covers the mounting frame from the front side, and an optical outlet that is attached to the mounting frame. (For example, patent document 1).
Japanese Patent Laying-Open No. 2005-73366 (FIG. 1)

  However, the optical outlet used for the information outlet for the conventional optical fiber, when the dimension occupying 1/3 of the longitudinal direction of the opening window of the mounting frame is defined as one module dimension, the dimension of the vessel is Since it is formed in three module dimensions, only one optical outlet can be attached to one attachment frame, and other wiring devices cannot be attached to one attachment frame.

  Therefore, if you want to connect a telephone cable (for example, for ISDN) or a LAN modular cable together with an optical fiber, either install a new mounting frame for the telephone line or LAN modular jack, or use it as a mounting frame. I had to use one with multiple open windows.

  In other words, in the past, when configuring an information outlet capable of connecting a modular jack and an optical fiber, a large installation area such as a wall surface is required to install an optical outlet and a wiring device having a modular jack for a telephone line or the like. Space (such as a space for mounting two mounting frames and a space for mounting a mounting frame with two opening windows), which not only deteriorates the appearance, but also attaches to mounting frames and embedded boxes. There has been a problem that such costs increase.

  The present invention has been made in view of the above points, and an object thereof is to provide an information outlet capable of saving space.

  In order to solve the above-mentioned problems, in the invention of the information outlet according to claim 1, the mounting frame having a rectangular opening window at the center, and the mounting frame with the front surface exposed from the opening window of the mounting frame When the dimension that occupies 1/3 of the longitudinal direction of the opening window of the mounting frame is defined as one module dimension, A first container having a first insertion port for a corresponding cable and having a first insertion port for a corresponding cable on the front side; and the optical outlet portion being formed in a module size and having a first module for an optical cable. The second container having two insertion ports on the front side, and the optical cable connection port formed on one end side are directed obliquely downward with respect to the horizontal direction and the second insertion port is connected to the second With the outside of the body facing Housed in 2 of the device body, wherein the optical cable to the other end and an optical connector to be connected.

  In the information outlet invention of claim 2, in addition to the configuration of claim 1, the wiring apparatus and the optical outlet part are attached to the mounting frame in a state where the wiring apparatus is positioned above the optical outlet part. An escape groove for an optical cable connected to the other end side of the optical connector is formed on the rear surface side of the first container.

  In the invention of the information outlet according to claim 3, in addition to the configuration of claim 1 or 2, the first insertion port of the wiring device is for a modular cable, and in the first container, A modular jack connected to the modular cable inserted from the first insertion port is provided.

  In the invention of the information outlet according to claim 1, since the first device body of the wiring apparatus is formed in one module size, and the second device body of the optical outlet portion is formed in two module sizes, The wiring device and the optical outlet can be attached to a mounting frame having one opening window. Therefore, when embedding and installing the wiring device and the optical outlet in the construction surface such as the wall surface, only one space for the mounting frame is required. There is no need for a space for the mounting frame, and as a result, the appearance is improved, and an increase in the cost of the mounting frame and the embedded box can be suppressed. Furthermore, since the optical connector of the optical outlet portion is housed in the second container with the optical cable connection port facing obliquely downward with respect to the horizontal direction, the thickness of the second container (front and rear) (Thickness in the direction) can be reduced, and when an optical cable is connected to the optical cable connection port of the optical connector, bending of the optical cable is weaker than when the optical cable connection port is oriented horizontally. There is an effect that can be done. In addition, since the other end side of the optical connector is oriented obliquely upward with respect to the horizontal direction, it is connected to the other end side of the optical connector as compared with the case where the other end side is oriented in the horizontal direction. The amount of protrusion of the optical cable from the optical outlet portion to the rear can be reduced, and the bending of the optical cable can be weakened, whereby the optical cable can be prevented from being damaged.

  In the invention of the information outlet according to the second aspect, the optical cable connected to the other end of the optical connector can be passed through the groove formed on the rear surface side of the first container. Since this eliminates the need to route the optical cable so as to avoid the first container, the amount of protrusion of the optical cable from the optical outlet can be further reduced. Even if the inside (back side) is narrow, there is an effect that an information outlet can be attached.

  The invention of the information outlet according to claim 3 has an effect that not only an optical cable but also a modular cable can be connected.

Two spaces or a space for two mounting frames are not required, and as a result, the appearance is improved, and an increase in the cost of the mounting frame and the embedded box can be suppressed.

  In particular, existing information outlets for telephone lines and LANs are often constructed by attaching two modular parts of one module size to a single mounting frame, so one modular part is mounted from the mounting frame. The information outlet 1 according to this embodiment can be installed simply by removing and replacing the optical outlet unit 3 instead. As a result, it is not necessary to provide a new mounting frame for installing the information outlet 1 or to replace the single mounting frame with a double mounting frame. There is an effect that can be done.

  Furthermore, since the optical connector 31 of the optical outlet 3 is housed in the second container 30 with the optical cable connection port C1 oriented obliquely downward with respect to the horizontal direction, the optical cable connection port C1. Compared with the case where the is oriented in the horizontal direction, there is an effect that the thickness (thickness in the front-rear direction) of the second container 30 can be reduced. In addition, since the optical cable connection port C2 of the optical connector 31 is oriented obliquely upward with respect to the horizontal direction, the optical cable connection port C2 is compared with the case where the optical cable connection port C2 is oriented in the horizontal direction. When the optical cable 7 is connected to C2, the protruding amount of the optical cable 7 from the optical outlet 3 to the rear can be reduced, and the bending of the optical cable 7 can be weakened, and the optical cable 7 can be prevented from being damaged. There is an effect.

  In addition, the modular unit 2 and the optical outlet unit 3 are attached to the mounting frame 4 with the modular unit 2 positioned above the optical outlet unit 3, and a groove 21 c is provided in the first container 20 of the modular unit 2. Therefore, when connecting the optical cable 7 to the optical cable connection port C <b> 2 of the optical connector 31, the optical cable 7 can be passed through the groove portion 21 c formed on the rear surface side of the first container 20. Therefore, when the optical cable 7 is connected to the optical cable connection port C <b> 2 of the optical connector 31, the first container 20 does not obstruct the connection of the optical cable 7. As a result, it is not necessary to route the optical cable 7 so as to avoid the first container 20, so that the amount of protrusion of the optical cable 7 from the optical outlet portion 3 can be further reduced, and as a result, the inner side (back side) of the construction surface X ) Has an effect that the information outlet 1 can be attached even if it is narrow.

  In this embodiment, the modular unit 2 is provided with a modular jack for a telephone line modular cable, but may be provided with a modular jack for a modular cable for LAN. Other wiring devices may be used, and they may be changed to suitable ones according to usage conditions.

  In this embodiment, the mounting frame 4 is made of synthetic resin. However, the mounting frame may be made of metal, or may be a combination of synthetic resin and metal. Good.
