Description

[Detailed description of the invention] This invention installs a plurality of electronic circuits, which are unitized into functional units constituting an electronic telephone exchange, etc., in parallel on a shelf of an equipment rack, and structures the electronic circuit units. The present invention relates to a line connection structure that allows connection of signal lines, etc., in a simple manner.

BACKGROUND OF THE INVENTION Due to the development of electronic technology, a plurality of electronic circuits, which constitute an electronic telephone exchange and are unitized into functional units, are becoming more densely packed, and the rooms in which they are installed are also becoming more densely packed.

Therefore, the packaging density in a single room is extremely high, such as by installing multiple electronic circuit units on the walls of the room, other equipment, etc., on the back of equipment racks with small gaps, or installing them in multiple stages from the floor to the ceiling.

In addition, when implementing unitized electronic circuits, there are cases where multiple units with the same function are arranged, circuit units with slightly different functions are installed adjacently, and even cases where completely different functions are installed adjacently. There are various mounting configurations, such as, but the conventional structure was that this was routed from a track on the back of the equipment rack to the back of the circuit unit using a cable with a connector, and then connected there.

If all signal processing is attempted to be achieved through the wiring on the back of the circuit unit, there will be a large amount of redundancy in the wiring on the back, making it uneconomical and limiting the flexibility in mounting the electronic circuit unit. Due to device configuration, 1. Undesirable.

Furthermore, with the backside wiring method, when the power supply needs to be stopped individually for maintenance, inspection, adjustment, etc., it is very inconvenient to remove and connect the devices.

Furthermore, in places where line connection is impossible, it is necessary to route the line in advance to a position where it can be connected, which not only severely limits the mounting position of electronic circuit units, but also makes it impossible to achieve high density. There were economical problems, such as the number of components used in the power supply line system, which required a large number of assembly steps.

Furthermore, when connecting various electronic circuit units with different connection patterns, the types and number of cables used increase, and therefore the wiring becomes difficult.

There were also drawbacks such as connection errors.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide a line connection structure for electronic circuit units that simplifies the installation rack structure for electronic circuit units and allows for rational line connection.

This invention lays out a common signal pattern to be connected to the electronic circuit units on the front surface of a horizontally long shelf on which multiple electronic circuit units are installed in parallel, and installs wiring boards equipped with connector connection terminals at predetermined intervals. Attachment, connect the connection terminal of the wiring board and the signal input terminal of the electronic circuit unit with a cable having connectors at both ends, and connect the signal line of the electronic circuit unit on the front side of the equipment rack, This eliminates the drawbacks of the prior art described above by standardizing the connection cables.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows an equipment rack structure on which a plurality of electronic circuit units 1 are mounted.The electronic circuit units 1 are approximately L-shaped and are fixed to pillars (not shown) on horizontally long shelves. It is listed in 2.

On the front surface of the folding piece 2a of the shelf 2, which is formed into an L-shape,
A wiring board 5 made of an insulating material on which horizontal signal lines 3 and vertical connector terminals 4 connected thereto are arranged as shown in FIG. 3 is attached.

Reference numeral 6 denotes a cable with connectors 7 and 8 attached to both ends, and is connected to the wiring board 5 and the plurality of electronic circuit packages 1a that constitute the electronic circuit unit 1 and have connection terminals on the front side by connector coupling. It is.

This connector 79.8 is shown on the wiring board side.

As shown in Figure 3, connect the cable to the terminal metal.

Reference numeral 9 denotes a cable having a connector 10 that connects a signal source (not shown) to the wiring board 5, and 11 a cable having a connector 12 that connects the wiring board 5 to another wiring board or other circuit unit. These are a plurality of electronic circuit units 1. connected by cables with connectors 6.9.11. The wiring board 5 and the like can all be operated from the front of the shelf 2.

FIG. 2 is an explanatory diagram of a case where signals are supplied to electronic circuit units having different wiring patterns using cables with connectors having the same structure from a wiring board on which a common wiring pattern is laid, and shows circuit units u□+u1. u2 is an electronic circuit package 1a that constitutes the electronic circuit unit 1.

These circuit units uQ+u□tu2 are the gate circuit 1
Signal line 3 (a +
becsdte) and connected by a cable.

In the figure, the circuit unit H□ has signal lines at Cs d
+ e, ul has a, b, c, u2 has by
dte and e are connected respectively.

All cables with connectors 6 shown in the figure can be used for all of the same type, and unnecessary signal lines can be disconnected by eliminating the wiring pattern in the circuit unit, that is, the electronic circuit package 1a, and can be used for any desired signal. Only human power can be used.

Regarding the wiring board 5 shown in FIG. 3, all the signal lines 3 required by the electronic circuit unit are installed.
The connector terminals 4 protruding from the connector housing 4a are attached by soldering or the like according to the same rules.

Therefore, when connecting signal lines to each electronic circuit unit, connect a cable 9 from a signal source (not shown) to the wiring board 5, and connect connectors 7 and 8 to both ends of the wiring board 5 from the nearest point. Each electronic circuit unit 1 receives a signal through the connector connection using the cable 6, and performs a predetermined function.

All of these cable connections are operated from the front of the shelf 2, and are connected by the same cable.

Although the above-described embodiments have been described with respect to signal line processing, the present invention is not limited to this and can be applied to power supply lines or a combination thereof.

As explained above, according to the present invention, all line connection operations such as electronic circuit units and signal lines can be performed at the front of the equipment rack, making it easy to operate. Since it can be used as a connection cable for electronic circuit units, it is possible to standardize connection cables and solve problems such as connection errors and uneconomical costs.
