Description

[Detailed Description of the Invention] [Summary] Regarding the structure of a connector panel for introducing an external line into the equipment in electronic equipment such as a telephone exchange, the present invention relates to the structure of a connector panel for introducing an external line into the equipment, which facilitates the installation and assembly of cables and improves work efficiency. In electronic equipment such as a telephone exchange, which is configured by housing a shelf in which a large number of packages are arranged in parallel in a cabinet, the connector extends across the entire width of the front surface of the shelf. Identify the panel, fix a cable duct along the lower front of the connector panel, and pull the bundle of external line cables introduced from the side of the shelf through the cable duct to the front position of the connector panel. From here, each external line is configured to be connected to each package in the shelf via a connection cable.

[Industrial Application Field] The present invention relates to the 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 containing packages 4 mounted with a large number of electronic components are stacked in multiple tiers, and these are stacked in a cabinet 2.
There are things stored inside. A plurality of external lines are bundled together and introduced as a plurality of cables 3 through a main distribution board (MDF) to an exchange, and are led into a connector panel 5 provided on one side of the front of each shelf 1 through a connector 6. It will be done. The cable 3 that has been drawn in is connected to a connector (not shown) that conforms to the user's standards on the back side of the connector panel 5, and from there the connecting cable 7
Connectors are further connected to the individual packages 4 along the cable duct 8 through the connectors.

When the external line cables 3 are drawn into the connector panel 5, as shown in detail in FIG. Cable 3 is installed in an orderly manner. The front surface of the connector panel 5 becomes a door 11, which can be opened and closed by a hinge 12 provided on one side. During maintenance, this door 11 is opened and the inside is opened as shown in FIG. wiring is accessible.

[Problem 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 wire arrangement plate 9, so when it is closed, the external line cable 3 must be pushed in by hand. Furthermore, as is clear from the figure, the length of the connection cable 7 from the connector panel 5 to each package 4 varies depending on the position of the package, and the farther from the panel 5 the longer the connection cable 7. You need to prepare a connection cable. Furthermore, in order to connect the two, it is necessary to lay out connection cables for each package row, with connectors attached to both ends, and assemble them to form an east line.

In this way, in the structure of the conventional connector panel,
Cable 4! Both the preparation and connection work required a lot of man-hours, and improvements were needed.

The present invention solves the problems in the prior art,
The purpose of the present invention is to provide a connector panel that facilitates the preparation and assembly of cables and improves work efficiency.

[Means to solve the problem]

The purpose of this is to fix a connector panel that extends over the entire width on the front surface of the shelf in electronic equipment such as a telephone exchange, which is configured by housing a shelf in which a large number of packages are arranged side by side in a cabinet. A cable duct is fixed at the lower front along this, and a bundle of external line cables introduced from the side of the shelf is drawn through the cable duct to the front position 1 of the connector panel, and from there, each cable is connected via the connecting cable. This is accomplished through the construction of a connector panel configured to connect external lines to each package within the shelf.

(Function) A 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. The cable bundle is then split into individual cables, each of which connects through a connector panel to each corresponding package in the shelf.

According to this configuration, the cables will not be disturbed even without a special wiring board, and since the distances from the connector panel to each package are all the same, the connection cables between the two can be of the same standard. There is no need to prepare many types of connection cables of different lengths as in the past.

Further, if the connector panel is made to be able to be pulled out forward with respect to the shelf, the wiring on the back side of the connector panel can be easily accessed during maintenance, which is convenient.

Hereinafter, the present invention will be explained in more detail based on preferred embodiments shown in the drawings.

〔Example〕

FIG. 1 is an exploded perspective view showing the structure 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 in front of the shelf 1, and is removably screwed to the left and right legs 14 of the shelf 1.

Along this connector panel 5, a cable duct 8 is horizontally fixed to the front surface of the shelf board 13.

FIG. 2 shows a state in which the external line cable 3 is introduced using the connector panel structure having such a configuration.

The bundle 3 of external line cables is MD along the shelf frame 15.
F, and those corresponding to each shelf 1 are branched from this and drawn directly into the cable duct 8 horizontally. Then, it is further branched for each package 4 in the shelf 1, and connected to the connector panel 5 by connector in order from the one corresponding to the package closest to the left end in the figure.

In the figure, reference numeral 16 indicates a connector for this purpose.

As shown in FIG. 3, the connector 16 is connected to the connector panel 5.
connector 17 of the connection cable 7 attached to the inner side of the
It is further connected to a connector (not shown) on the package side via a connector 18 at the other end. As is clear from the figure, all of the connection cables 7 have the same length, so if you prepare a large number of cables of a predetermined length with connectors 17 and 18 attached to both ends, you can store them inside the shelf. 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 that fix the connector panel 5 to the shelf 1, and pull the connector panel 5 forward. can be easily accessed.

[Effects of the Invention] As described above, according to the present invention, the following effects can be obtained.

■ Connecting cables, which conventionally had different lengths depending on the position of each package, can now all be of the same standard, making it easier to manufacture them.

■ The structure is simplified because the wiring board that was conventionally attached to the connector panel for handling external line cables is no longer required, and the opening/closing mechanism for the connector panel is also no longer required.

■ Easier installation of external line cables, reducing man-hours.
