Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a built-in housing information board that can be embedded in a wall or the like.

[Background Art] Some conventional embedded housing information boards have connecting terminals exposed on the back surface, and signal lines, power lines, etc. wired inside the wall are connected to the connecting terminals.
However, this embedded type housing information panel is relatively heavy, and the signal line etc. must be connected to the connection terminal while supporting the embedded type housing information panel, which poses a problem of poor workability.

Therefore, a recessed type house is constructed using a base to which heavy components such as a terminal block and power supply block are attached to which electric wires routed inside the wall are connected, and a cover to which lightweight components other than those attached to the base are attached. The information panel is formed, and the base is first embedded in the hole drilled in the wall and installed, the electric wires routed inside the wall are connected, and then the base and cover are connected using connectors, and the cover is installed. There are some that are coated on a base. In the case of this embedded housing information panel, wiring can be done after the base is attached to the wall, and the cover is lightweight, and the wire connection between the base and cover is done with a connector.
Easy to wire with the base and has good workability.

However, when the terminal block is placed inside the base, the terminals of the terminal block are not exposed from the back, so when checking the operation at the time of shipment, the cover must be removed from the base each time, and the signal can be connected to the terminals of the terminal block. There was a problem in that the wires had to be connected and then inspected, making shipping inspection very time-consuming.

[Purpose of the invention] The present invention has been made in view of the above-mentioned points, and its purpose is to provide an embedded housing information board that can be easily inspected before shipping.

[Disclosure of the invention] (Example) An embodiment of the invention is shown in FIGS. 1 to 7.
The embedded housing information panel of this embodiment has terminal blocks 15, 1

This protective cover 10 has insertion holes 43 to 45 for connector receivers 24 to 26 to which connectors of the base 2 are connected.

As shown in FIG. 1, the base 2 is box-shaped with an open front, and a flange 27 that contacts the display on the wall surface 8 is provided around the periphery of the opening. The back plate 28 of the base 2 has two cylindrical protrusions 29 with closed upper surfaces protruding inward at two locations, upper and lower.
Screw 4 from the surface of the cover 1 onto the top surface of this protrusion 29.
A screw hole 30 for screwing 6 is bored. In addition, a rectangular hole 42 is bored in the center of the upper part of the back plate 28, and an electric wire 37 such as a signal line or a power line wired inside the wall surface 8 is connected to the base 2 through this hole 42.
Pull inside. Terminal blocks 15 on the left and right of this hole 42,
A plurality of cylindrical bosses 31 with thick internal diameter screw holes for screwing the terminal blocks 16 are provided in a protruding manner so that terminal blocks 15 and 16 having various numbers of terminals can be attached. Inspection holes 32 are bored between the bosses 31 at positions corresponding to the respective terminals of the terminal blocks 15 and 16.
A signal is input to the terminal through 2 to check whether the housing information board operates normally. Furthermore, a horizontally long protrusion 33 is formed slightly above the lower protrusion 29 in the drawing. Since the power supply block 7 equipped with a heavy transformer is attached to the part where this protrusion 33 is formed, this power supply block 7
A protrusion 33 is formed to prevent the printed circuit board (not shown) from bending inward. The printed circuit board of the power supply block 7 is attached to the base 2 by screwing it to a boss 31 having screw holes similar to those of the terminal blocks 15 and 16. Further, a vertically elongated protrusion 34 formed approximately at the center of the back plate 28 prevents the printed circuit board (not shown) from bending when replacing the fuse. Screw holes 35 for screws 47 for screwing the base 1 to the wall surface 8 are bored in various places on the flange 27 of the base 2, and the handset 9 is attached to the mounting part 12 in the flange part at the upper left in the figure. A protruding rib 36 is provided to prevent the printed circuit board from sinking due to the force applied when it is mounted. Further, a slit 40 is formed in the upper part of the back plate 28 in FIG. 1b. In other words, for such a housing information board, the base 2 and cover 1 must not be electrically separated in the fire safety certification.
Pass the string tied to the cover 1 through the slit 40 and sandwich it between the terminal blocks 15 and 16, and then close the cover 1.
and base 2 are made so as not to separate. As shown in FIG. 5, a knock-out portion 38 is formed on one side of the base 2, which is thinner than the other side so that a hole can be easily punched. It is arranged so that electric wires 37 and the like wired to can be drawn in. In other words, if the depth of the wall surface 8 does not have enough margin for the width in the depth direction of the base 2 as shown in FIG. It is not possible to draw from 42. Therefore, a knockout portion 38 is formed as a preliminary to the hole 42. Furthermore, as shown in FIGS. 1 and 5, the upper and lower flanges 27 have ribs 39 for positioning when attaching the cover 1 to the base 2.

It also serves as a preventive measure against falling.

The construction procedure will be explained below with reference to FIG. First, the base 2, on which the terminal blocks 15, 16 and the power supply block 7 are attached as described above, is fixed with the screws 47 and attached to the embedding hole 11 drilled in the wall surface 8. Then, the electric wires 37 and the like wired inside the wall surface 8 are connected to the terminal blocks 15 and 16. If the base 2 is provided with the terminal blocks 15 and 16 in this manner, connection of the signal line 37 and the like can be easily performed. Then, the electrical connection between the cover 1 and the base 2 is completed by connecting the connectors 21 to 23 pulled out from the terminal blocks 15 and 16 and the power supply block 7 to the connector receivers 24 to 26 on the back side of the cover 1.
At this time, the heavy parts are installed in the base 2 and the parts housed in the cover 1 are lightweight parts, so the cover 1 is lightweight and can be easily held, and the connector 21 -23 connection work can be done easily. Then, if cover 2 is attached to base 1 and screwed with screws 46,
A cover 1 can be applied to the base 2. In this state, the connector 41 of the handset 9 is fitted into a connector receiver (not shown) provided on the cover 1, thereby completing the construction of the housing information panel.

Incidentally, such an embedded housing information panel is shipped with the connector connected and the cover 1 attached to the base 2 so as not to be bulky when packed. Therefore, when performing a shipping inspection, the terminal block 15,
16 is not exposed, it is necessary to remove the cover 2, and it is time-consuming to check the operation at the time of shipment. However, in this embodiment, the terminal blocks 15, 1
Since inspection holes 32 are drilled at positions corresponding to the respective terminals of terminals 6 and 6, test signals can be input to the terminals of terminal blocks 15 and 16 through these inspection holes 32 to check whether the housing information panel operates normally. can be inspected,
Operation confirmation at the time of shipment can be easily performed.

[Effects of the invention] As described above, the present invention has inspection holes that expose the respective terminals of the terminal block on the mounting surface of the terminal block of the base, so that inspection signals can be input as appropriate through these inspection holes. This eliminates the need to remove the cover and makes it easy to confirm operation at the time of shipment.
