Description

[Detailed description of the invention] The present invention relates to a meter, in which a terminal board for connecting external wiring is arranged at at least one of the upper and lower ends of the opening of a printed wiring board in which internal components are arranged. In instruments that are removably stored in a case with
To provide an integrated meter by incorporating a cover integrated into the front plate of a printed wiring board, which has a terminal board cover function, a printed wiring board handle function, and a name plate display function.

FIG. 1 is a configuration explanatory diagram showing an example of a conventional meter of this type, and 10 is a printed wiring board on which internal components (not shown) are arranged, and a card edge contact is provided at the insertion end. A handle portion 20 is formed at the pull-out end opposite to the insertion end.

Reference numeral 30 denotes a case in which the printed wiring board 10 is housed, and a connector 21 that fits into the card edge contact portion 11 of the printed wiring board 10 is arranged on the back side in the depth direction.

40 and 50 are terminal blocks arranged on the opening surface of the case 30, and external wiring 0UT1.

0UT2 is connected.

Further, these terminal blocks 40, 50 and the connector 21 are connected via cables C1 and C2 arranged inside the case 30.

60.70 is a terminal cover that covers the surface of the terminal block 40°50.

With this configuration, the terminal block 40.5
The printed wiring board 10 can be inserted into and removed from the case 30 without removing the printed wiring board 0 from the case 30.

However, according to such a configuration, the terminal cover 60.7
0 is external wiring 0UTl.

When connecting or checking 0UT2, it must be removed from the terminal block 40, 50, and there is a risk of losing it.

In addition, since the terminal covers 60 and 70 can be removed, if multiple instruments are arranged side by side, there is a risk that the correspondence between the instruments and the terminal covers will not be established, so the terminal cover should not be used as a name plate display section specific to the instruments. I can't.

Further, according to the configuration shown in FIG. 1, the printed wiring board 1
0 has a disadvantage in that the grip portion of the handle 20 is small, making it difficult to insert and remove the printed wiring board 10.

The present invention solves these drawbacks and will be described in detail below with reference to the drawings.

FIG. 2 is a configuration explanatory diagram showing an embodiment of the present invention,
A shows a state in which the inner device is inserted and removed, and b shows a state in which the inner device is stored.

In the drawings, reference numeral 80 denotes a case, which is formed into a cylindrical shape with one end open.

90 is a bracket attached to the opening of the case 80, and 100 and 110 are terminal boards placed at the upper and lower ends of the opening so as to be sandwiched by the bracket 90.

120 is a printed wiring board on which internal components (not shown) are arranged, and 130 is a drawn-out end 12 of the printed wiring board 120.
This is the front plate attached to 1.

The front plate 130 is formed into a U-shaped cross section so as to close the opening of the case 80.

Reference numerals 140 and 150 are integrated with covers, one end a of which is rotatably supported by the side surfaces 131 and 132 of the front plate 130, and the other end of which has a U-shaped cross-section as part of the cover that covers the control plates 100 and 110. It is molded into.

Both sides of these covers are 140° and 150° c,
d is formed as a name plate display section for displaying predetermined information symbols (terminal name, tag number, instrument name, etc.) as shown in the shaded area.

The operation of the device configured in this way will be explained.

First, when inserting or removing the printed wiring board 120, rotate the integrated cover 140° 150 as shown in FIG.
150 is used as a handle.

On the other hand, after inserting the printed wiring board 120, as shown in FIG. 2, the covers 140, 150 are rotated so that the covers partially cover the predetermined terminal boards 100, 110.

In addition, a predetermined name plate will be affixed to each cover.

Further, a locking mechanism may be provided on the side surface of the front plate 130 or on the bracket 90 for fixing the integrated cover 140s150 in a state covering the terminal boards 100, 110.

In addition, when pulling out the printed wiring board 120,
The integrated covers 140 and 150 may act as levers against the bracket 90.

As is clear from the above, according to the present invention, the integrated covers 140 and 150 are integrally attached to the front plate 130, so the integrated covers 140 and 150 are attached during wiring work and checking.
All you have to do is turn the 150, there is no need to store it, and there is no risk of losing it.

Furthermore, since the gauges and the integrated cover always correspond to each other, the integrated cover can be used as a name plate display means.

Furthermore, since the integrated covers 140 and 150 can be rotated and used as handles for inserting and removing the printed wiring board 120, the handles are large and strong, and insertion and removal operations can be performed quickly and reliably.

In the above embodiment, an example of an instrument in which the terminal board was provided at both the upper and lower ends of the opening of the case was described, but the terminal board may be provided at only one of the ends.
