To connect each external line to each package in the shelf via.

[Industrial application field]

The present invention relates to a structure of a connector panel for introducing an external line into an electronic device such as a telephone exchange.

[Conventional technology]

As a type of telephone exchange, as shown in FIG. 4, a plurality of shelves 1 accommodating a plurality of electronic components mounted in parallel are stacked and stacked in a plurality of cabinets.
Some are stored inside. A plurality of external lines are bundled and introduced as a plurality of cables 3 to a switchboard through a main distribution board (MDF), and drawn into a connector panel 5 provided on one side of the front of each shelf 1 through a connector 6. Be done. The pulled-in cable 3 is connected to a connector (not shown) conforming to the user's standard on the rear surface side of the connector panel 5, and from here, through the connecting cable 7 along the cable duct 8 to the individual packages 4. Connector is connected.

When pulling in the external line cable 3 into the connector panel 5, as shown in detail in FIG. 5, a wire arranging plate 9 is provided in order to reduce variations in each cable, and slits 10 provided in each of the arranging plates 9 are used to The cables 3 are introduced in an orderly manner. And the front surface of the connector panel 5 becomes a door 11,
It is constructed so that it can be opened and closed by a hinge 12 provided on this one side. During maintenance, as shown in FIG.
Open to access the internal wiring.

[Problems to be Solved by the Invention]

In such a configuration, when the door 11 is opened, the external line cable 3 comes off from the slit 10 of the rectifying plate 9, and therefore, it must be pushed by hand when closed. Furthermore, a connection cable 7 from the connector panel 5 to each package 4
As is clear from the figure, the length of the is different depending on the position of the package, and the longer the distance from the panel 5, the longer the connecting cables need to be prepared. Further, in order to connect the both, it is necessary to braid the connecting cable in a row unit of the package with the connectors attached to both ends and to assemble and bundle them.

Thus, in the structure of the conventional connector panel,
A lot of man-hours were required for cable preparation and connection work, and improvements were required.

The present invention solves these problems in the prior art,
An object of the present invention is to provide a connector panel in which cable preparation and assembly are easy and work efficiency can be improved.

[Means for Solving the Problems]

1. The purpose is to fix a connector panel extending over the entire width to the front surface of the shelf in an electronic device configured by housing a shelf accommodating a large number of packages in parallel in a cabinet, and further to further connect the connector panel. A cable duct is fixed along the lower front of the shelf, and a bundle of external line cables introduced from the side of the shelf is drawn through the cable duct to the front position of the connector panel, and from here, each external cable is connected via a connecting cable. This is accomplished by the construction of a connector panel characterized by connecting a line cable to each package in the shelf on its front side.

[Action]

The bundle of external line cables is introduced through the cable duct to the front of the connector panel installed on the front of the shelf. Here, the bundle of cables is divided into individual cables, each of which is connected to a corresponding package in the shelf through a connector panel.

According to this configuration, the cable will not be disturbed without a special wire arranging plate, and since the distances from the connector panel to each package are all the same, the connection cables between the two will be of the same standard and in time, It is not necessary to prepare many kinds of connecting cables having different lengths as in the conventional case.

Further, if the connector panel can be pulled out forward with respect to the shelf, the wiring on the rear surface side of the connector panel can be easily accessed for maintenance, which is convenient.

Hereinafter, the present invention will be described in more detail with reference to the preferred embodiments shown in the drawings.

〔Example〕

FIG. 1 is an exploded perspective view showing a configuration of a shelf of a telephone exchange equipped with the connector panel structure of the present invention.

The shelf 1 is placed and fixed on a shelf board 13, and a connector panel 5 is installed over the entire width on the front surface thereof, and is detachably screwed to the left and right legs 14 of the shelf 1.

A cable duct 8 is horizontally fixed to the front surface of the shelf board 13 along the connector panel 5.

FIG. 2 shows the introduction state of the external line cable 3 having the connector panel structure having such a configuration.

The bundle 3 of external line cables is introduced from the MDF along the shelf frame, and the one corresponding to each shelf 1 branches from this and is directly drawn horizontally into the cable duct 8.
Then, the packages corresponding to the respective packages 4 in the shelf 1 are further branched, and the packages corresponding to the packages closer to the left end in the figure are connected to the connector panel 5 in order. In the figure, reference numeral 16 indicates a connector for this purpose.

As shown in FIG. 3, the connector 16 is fitted to the connector 17 of the connection cable 7 attached to the inner surface side of the connector panel 5, and is further connected to the package side connector (not shown) via the connector 18 at the other end. It is connected. As can be seen from the figure, all of the connecting cables 7 have the same length, so if you prepare a number of cables with connectors 17 and 18 attached to both ends of the cable of the specified length in advance, It can be used for packages in any position.

When attaching the connection cable 7 during assembly or maintaining the cable after assembly, remove the screws 19 fixing the connector panel 5 to the shelf 1 and pull out the connector panel 5 to the rear side. Can be easily accessed.

〔The invention's effect〕

As described above, according to the present invention, the following effects can be obtained.

Conventionally, all connection cables having different lengths depending on the position of each package can be unified to the one having the same standard, which facilitates the production.

Conventionally, the wire arranging plate attached to the connector panel for handling the external line cable is not required, and the opening / closing mechanism of the connector panel is not required, so that the structure is simplified.

The work of installing the external line cable becomes easy and the number of steps is reduced.
