Abstract

PURPOSE:To execute easily the connecting work by connecting, through a conductor pattern of a printed board, a U slit-shaped press-contacting terminal plate or a connector which are to be connected to an external line actually mounted at one side edge of the print board, and a U slit-shaped press- contacting terminal plate or a connector which are to be connected to a device side connecting line actually mounted at the other side edge, and installing a wiring board, to which the necessary equipment is actually mounted to a printed board, in parallel to a frame. CONSTITUTION:An external line 2 pulled in from the upper part of a frame 1 is separated to an element wire, and is respectively connected to the terminal of a U slit-type press-contacting terminal plate 23 mounted at one side of a wiring board 20 or wiring board 30. The element wire of a device side connecting line 3 is respectively connected to the terminal of the U slit-shaped press-contacting terminal plate 23 mounted at the other side of the wiring plate 20, or inserted to a connector 33 actually mounted at the other side of the wiring board 30. Since a protector 24 and a jack 25 for test are also connected through the conductor pattern, a special connecting work is not needed.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to improvements in wiring board racks for switching equipment.

External lines such as subscriber lines or connection lines with other stations are generally introduced into the exchange through a wiring board rack. This wiring board rack is equipped with necessary equipment such as protectors and test jacks to protect the exchange and facilitate testing.

At this time, the wiring board rack is required to be able to easily connect external lines and device side connection lines.

[Conventional technology]

FIG. 5 is a perspective view of a conventional wiring board rack, FIG. 6 is a perspective view of a terminal board, and FIG. 7 is a perspective view of essential parts of the terminal board.

In Fig. 5, a plurality of vertical supports are arranged in parallel on the frame 1, and each vertical support has a terminal plate 4°, a protector plate 4^,
Test jacks 4B and the like are fixed in parallel.

The external wire 2 drawn in from the top of the frame 1 is connected to the terminal plate 4.
To the terminals of the terminal row parallel to one side of the protector board 4^, etc.
The terminals of the terminal row that are connected and parallel to each other on the other side are connected to the device side connection line 3. Alternatively, it is configured to be connected to a test jack board 4B or the like.

Then, the terminal board 4, as shown in FIGS. 6 and 7,
Mounting plates 5 are fixed in parallel to each vertical support, and terminal plates 4 are fixed to the mounting plates 5.

On the terminal board 4, a large number of solder terminals 10 pass through a housing plate 9 made of a rectangular insulator in parallel.
A plurality of such housing plates 9 are stacked and screwed to the mounting plate 5, and holes 8 into which strands 7 can be loosely inserted are arranged in parallel on both sides of the insulating plate 6 to which the housing plates 9 are fixed. It is provided.

The terminal board 4 configured in this manner is configured to be attached to the mounting plate 5 by screwing the insulating plate 6.

The external wire 2 is separated into individual wires 7, passed through holes 8 arranged in parallel on one side, pulled out from the rear of the insulating plate 6 to the housing plate 9 side, and connected to one tip of the solder terminal 10. , soldered and fixed.

On the other hand, the strand 7 soldered to the other tip of the soldering terminal 10 passes through the holes 8 arranged in parallel on the other side and is pulled out to the rear of the insulating plate 6 to become the device-side connection wire 3. Connected to switching equipment. In addition, some of the terminals on the terminal board 4 are
It is connected to the adjacent protector board 4A and test jack board 4B by jumper wires 11.

The protector plate 4^ has almost the same structure and terminal arrangement as the terminal plate 4 when attached to the mounting plate 5, but a protector such as an arrester is mounted in place of the housing plate 9. Further, the test jack board 4B has almost the same structure as the terminal board 4 when attached to the mounting plate 5, but a test jack in which wrapping terminals are arranged in parallel is mounted.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional wiring board rack does not support external lines.

Connections between the device side connection wire, test jack board, and protector board are made by soldering or wrapping,
There is a problem that the connection work is troublesome, and since the protector board and the test jack board are installed separately from the terminal board, there is a problem that they are large.

[Means for solving problems]

The problem with the above conventional method is that the U slit type crimp terminal board or connector is mounted on one side edge of the printed circuit board to connect to the external wire, and the U slit type crimp terminal board or connector is mounted on the other side edge to connect to the device side connection wire. What is a slit type crimp terminal plate or connector?
The problem is solved by the wiring board rack of the switching equipment of the present invention, in which wiring boards connected via conductor patterns of the printed board and required equipment mounted on the printed board are arranged in parallel on a rack frame.

[Effect]

According to the means of the present invention, the external line and the device side connection line are connected to the wiring board by either crimping the U-slit crimp terminal plate, inserting a connector, or the like. Since the connection is made via the conductor pattern on the printed board, the connection is extremely easy. Furthermore, since the protector and test jack are mounted on the printed circuit board of the wiring board, no special connection space is required and the device is compact.
