Description

The present invention relates to a patch panel for mounting various adapters including SC adapters and LC adapters for optical communication in an information wiring system.

Conventionally, in offices, factories and the like, an information wiring system using a twisted pair cable has been widely used in order to transmit various information such as voice signals, digital signals such as LAN, and image signals. In such an information wiring system, a relay terminal board called a patch panel is used to support the wiring work of the network in case the information wiring needs to be changed due to the layout change of the office or the like. ..

Specifically, a patch panel for mounting a modular adapter for a telephone shown in Patent Document 1 is known. This patch panel is attached to the panel body by arranging 4 mounting frames in a row (24 modular adapters in total) that hold 6 modular adapters to which modular plugs are detachably connected in a row. The main body is configured to be attached to a fixed part such as a rack in upper and lower stages.

A substantially U-shaped electric wire fixing piece projecting from the lower edge of the panel body to the back side is continuously formed integrally with the panel body. The electric wire fixing piece is composed of a central piece and a connecting piece that connects both ends thereof to the panel body, and a binding band for binding the electric wire connected to the modular jack is inserted into the central piece and the connecting piece. Insertion holes are drilled in the central piece and the connecting piece, respectively, so that the cable can be pulled out in a desired direction.

Further, conventionally, as shown in FIG. 16, a patch panel that enables the adapter mounting frame 101, which is mounted by appropriately combining adapters Q for every 6 ports to form a total of 24 pieces, to be attached from the front side of the panel main body 102. A plurality of cables K are fixed as a set to a tap plate 105 horizontally laid on the rear end side of the side frame 104 which forms P and projects from both ends of the back surface of the panel body 102 toward the rear. The holder piece member 106 is provided.

Japanese Patent No. 3482907

However, the mounting frame according to Patent Document 1 described above is for mounting the 6 ports (6 pieces) of the telephone modular adapter together on the panel, and is used as an SC adapter for electrical or optical communication in an information wiring system. It does not attach an LC adapter.

Further, in Patent Document 1 described above, in the central piece of the electric wire fixing piece of the panel body, a plurality of insertion holes for inserting a binding band for binding the electric wire connected to the modular jack are formed at equal intervals. Because it is not possible to pull out all the wires from both ends of the wire fixing piece while changing the bending position of all the wires, the wires hanging at regular intervals on the rear side of the panel body like a cane. Are messed up and entangled with each other, and there is a risk that changes in information wiring and maintenance work due to reasons such as changes in the layout of offices will become extremely complicated.

Further, in the conventional patch panel P shown in FIG. 16, since the holder piece member 106 does not have a protrusion for preventing rotation with respect to the tap plate 105 laid horizontally on the rear end side of the side frame 104, a pair of cables is used. When the holder piece member 106 holding K is fixed to the tap plate 105, the holder piece member 106 rotates on the tap plate 105, causing excessive tension or bending in the cable K itself, thereby damaging the communication function. In addition to the possibility of giving the cable K, the holder piece member 106 faces apart on the tap plate 105, so that there is a problem that it takes time and effort to set the cable K.

Moreover, in the conventional patch panel P shown in FIG. 16, since there is no portion on the rear side of the tap plate 105 for bundling and holding the cable K with a binding band, the cable hangs down like a bamboo blind from the rear part of the tap plate 105. There is a risk that the K's will cross each other randomly and become entangled with each other.

Therefore, the present invention has been devised in view of the above-mentioned conventional circumstances, and the bending positions of all the cables of the plugs connected to each adapter mounted on a plurality of adapter mounting frames are set. By pulling out all the cables and bundling them with a binding band while holding them on both ends of the panel body while changing them as appropriate, it is possible to prevent the cables from being randomly crossed and entangled with each other on the rear side of the panel body. In addition, when fixing the holder piece member that holds the cable to the tap plate of the adapter mounting frame, it is possible to prevent the holder piece member from rotating on the tap plate and causing excessive tension or bending in the cable itself. At the same time, the purpose is to provide a patch panel that enables efficient cable setting work.
