Description

[Detailed Description of the Invention] This invention relates to an indicator light panel in which indicator lights are arranged in a matrix.

Generally, when the presence or absence of signals from a plurality of signal sources is indicated by a plurality of corresponding indicator lights, such as in a fire alarm receiver, a dynamic display method is adopted in order to reduce the number of connections.

In display using this dynamic display method, indicator lights are arranged in a matrix on the display board, and the indicator lights are provided with a common X-axis signal line for each row and a common Y-axis signal line for each column. An indicator light panel connected to the

Conventionally, as this type of indicator light panel, there has been one shown in FIG.

This indicator light panel has indicator lights 2 arranged in a matrix on a display board 1 to which X-axis signal lines 3 and Y-axis signal lines 4 are connected.

To connect the signal lines, first connect the common signal lines 3 and 4 for each row or column to the lead terminals of the indicator lights 2 placed at the ends of the display board 1, and then For each row of rowers, the lead terminal of the indicator lamp 2 to which the signal line 3 or 4 was connected was sequentially connected to the adjacent indicator lamp 2 via the relay line 5.

However, this conventional indicator light panel has the following drawbacks.

That is, in the vicinity of the lead terminal of the indicator light 2, the X-axis signal line 3 and the Y-axis signal line 4 may intersect and cause a short circuit, so it is necessary to cover these signal lines 3 and 4 with an insulating tube, etc. special insulation treatment was required.

Also, in most indicator lights 2, one lead terminal has two
Since the actual signal wires are soldered, the soldering work becomes complicated and there is also the risk of short circuits due to solder between the lead terminals.

Furthermore, when replacing the indicator light 2, it is necessary to remove not only the indicator light 2 but also the relay wires to other adjacent indicator lights 2, making the work of removal and subsequent reinstallation complicated. .

This idea was made to solve these drawbacks,
To provide an indicator light panel in which there is no risk of short-circuiting of X-axis and Y-axis signal lines near lead wires of the indicator light, easy soldering, and easy replacement of indicator lights.

In other words, this invention uses a printed circuit board in which one of the X or Y busbars is provided in a strip shape in the longitudinal direction, and a plurality of relay terminals for the other busbar are provided at regular intervals, and indicator lights are arranged in a matrix. The indicator lights are attached to each row or column of the matrix on the board, and the lead wires of the indicator lights are connected to either the X or Y bus bar and relay terminal of the printed circuit board, and the leads are connected between adjacent printed boards. The other bus bar is successively connected to the relay terminal of the bus.

This invention will be explained below based on embodiments shown in the drawings.

The embodiment shown in FIGS. 2 and 3 consists of a display board 1 on which indicator lights 2 are arranged in a matrix, and a printed circuit board 6 attached to the display board 1. 7 and a relay terminal 8 for the Y bus 9.

In the figure, a display board 1 is a board made of, for example, acrylic resin, and has through holes 1a arranged in a matrix, and indicator lights 2 are inserted and attached to the through holes 1a.

Further, a printed circuit board 6 is attached to the back surface thereof.

The indicator light 2 indicates the presence or absence of a signal from the signal line, and is, for example, a light emitting diode or the like housed in a suitable bracket.

The indicator light 2 is inserted into a through hole 1a provided in the display board 1, and fixed to the display board 1 with a nut 2b via a washer 2c to form a matrix.

Further, the lead wire 2a is connected to a relay terminal 8 of an X bus bar 7 and a Y bus bar 9 provided on a printed circuit board 6, which will be described later.

The printed circuit board 6 is made of an insulating substrate made of bakelite, epoxy resin, etc., and one surface is coated with a conductor such as copper, and the relay terminals 8 of the X bus bar 7 and the Y bus bar 9 are connected by known means such as etching. It has been established.

The printed circuit board 6 is attached substantially perpendicularly to the display board 1 using L-shaped fittings 10 for each row of the matrix constituted by the indicator lights 2.

Note that by providing an appropriate through hole or notch in the relay terminal 8 portion of the printed circuit board 6, connection between the relay terminal and the bus bar can be facilitated.

The X bus line 7 and the Y bus line 9 are for transmitting the X-axis signal and Y-axis signal from the signal line to the indicator lamp 2, respectively, and there is one for each row of the matrix that the indicator lamp 2 forms. establish.

The X busbar 7 is provided in a strip shape in the longitudinal direction on the printed circuit board 6 by printed wiring.

On the other hand, the Y bus bar 9 is formed by sequentially soldering one conductive wire to the relay terminals 8 provided on the printed circuit board 6, or by sequentially connecting each relay terminal 8 with a relay conductor. .

The ends of both bus lines 7 and 9 are connected to the X-axis signal line 3 for each row and the Y-axis signal line 4 for each column, respectively.

As shown in FIG. 3, a through hole 8a is provided in the relay terminal 8 portion of the printed circuit board 6.
If the Y busbar 9 is wired by inserting the Y busbar 9 through the Y busbar, supporting and soldering of the Y busbar can be facilitated.

In this embodiment, the relay terminal 8 is used to relay the Y bus 9 and to connect the Y bus 9 and the lead wire 2a of the indicator light 2.

Therefore, a plurality of relay terminals 8 are provided at regular intervals on the periphery of the printed circuit board 6, corresponding to each row of the matrix of indicator lights 2, so as to be at the top when attached to the display board 1.

Further, this relay terminal 8 is provided apart from the above-mentioned X bus bar 7 to electrically insulate the two.

However, it goes without saying that its formation can be carried out simultaneously with the X busbar 7 and by the same means.

According to this configuration, the signal lines 3 and 4 can be connected to each indicator lamp 2 by the X bus 7, the relay terminal 8, and the Y bus 9 provided on the printed circuit board 6, which is conventionally complicated. It is possible to simplify the wiring connections.

Moreover, by providing the X bus bar 7 and the relay terminal 8 at a distance apart from each other on the printed circuit board 6, and by providing the relay terminal 8 at the upper peripheral portion of the board 6, the X bus bar 7 and the Y bus bar 9 There is no risk of short-circuiting at the intersection, and there is no need for any special insulation treatment that has conventionally been required for relay lines.

Also, both lead wires 2 of the indicator light 2 are connected on the same side of the printed circuit board 6.
Since the soldering of step a can be performed, the soldering work becomes extremely easy, and short circuits caused by soldering between the lead wires can be completely eliminated.

Furthermore, when replacing the indicator lamp 2, it can be easily done by cutting only the lead wire 2a of the indicator lamp 2 and removing the nut 2b, so that other indicator lamps 2 are not affected in any way.

In the above embodiment, an X bus bar 7 is provided on the printed circuit board 6 and is attached to each row of the matrix of indicator lights 2, but conversely, a Y bus bar 9 is provided on the printed circuit board 6 and is attached to each column of the matrix. It can also be installed on.

Further, it can be arbitrarily determined whether each X bus line 7 or each Y bus line 8 corresponds to each row or column of the matrix of indicator lights 2.

As explained above, by configuring the device as described above, the wiring connection can be simplified, and there is no danger of a short circuit between the X-axis and Y-axis signal lines near the lead wires of the indicator light.
It is possible to obtain an indicator light panel that is easy to solder and whose indicator lights are easy to replace.
