Description

[Detailed description of the invention] The invention relates to an embedded signal device,
The objective is to provide an embedded signal device in which the bulkhead plate can be easily attached and removed as needed.

Conventionally, in order to ensure insulation between the power supply wiring and the low-power wiring of an embedded signal device, a bulkhead plate was installed on the back side of the embedded signal device, but the bulkhead plate was removable. Because of this, the bulkhead board gets in the way and makes wiring work difficult, and even if the power supply wiring is relatively low voltage wiring (e.g. 12V, 6V) and the bulkhead board is not required, it is necessary to remove the bulkhead board. Therefore, there was a problem in that the method of wiring was restricted by the partition wall plate, and rational wiring (for example, bundling of wiring) was not possible.

The present invention has been made in view of the above points.

Examples will be described below using figures. Figures 1 to 6 show one embodiment of the present invention.
2 is a built-in box embedded in the wall 10, and 2 is a signal device body such as an intercom.
The housing 11 has a protruding center portion on the back surface, and a relatively large component such as a transformer is accommodated in this protruding portion 12. Reference numeral 5 denotes a mounting groove into which the side edge of the partition wall plate 3 is inserted, and is formed by two parallel protrusions 13 extending in the vertical direction and protruding from the center of the back surface of the protrusion 12. Fitting ribs 14 are provided at appropriate locations within the holder 5. Reference numeral 6 designates an engagement hole for a hook 4 projecting from the upper end of the partition plate 3, and is formed on the upper surface of the protrusion 12. 7 is a connection terminal for power supply wiring such as a commercial power source, and 8 is a connection terminal for low power wiring such as a signal line. Both connection terminals 7 and 8 are provided on both sides of the mounting groove 5, and both The partition plate 3 is arranged so as to separate the wiring connected to the connection terminals 7 and 8.
As shown in FIG. 6, the partition plate 3 has an L-shaped hook 4 protruding from the upper end of the side edge that is fitted into the mounting groove 5, and is fitted into the fitting rib 14 at the center of the side edge. A plurality of break lines 18 consisting of round holes 16 and linear holes 17 are formed in the vertical direction at the center in the width direction. Depending on the depth of the embedded box 1, the partition wall plate 3 is
The width can be adjusted.

To install the bulkhead plate 3, first hook the hook 4 of the bulkhead plate 3 into the engagement hole 6 on the top surface of the protrusion 12 as shown by the imaginary line, and then attach the bulkhead plate 3 as shown by the arrow in the figure. The side edge of the partition plate 3 is fitted into the mounting groove 5, and the mounting groove 5 is inserted into the notch 15 of the partition plate 3.
By fitting the inner fitting ribs 14, it can be easily and reliably attached, and when it needs to be removed, it can be easily removed by a reverse operation. In the embodiment, chamfered portions 4a, 15 are provided on the hook 4 and the fitting notch 15 in order to facilitate the rotation of the partition wall plate 3.
A is provided.

As mentioned above, the present invention provides a mounting groove in the vertical direction into which the side edge of the bulkhead plate is inserted in the center of the back side of the signal device body housed in the recessed box, and a mounting groove on the top surface into which the side edge of the bulkhead plate is inserted. An engagement hole for a protruding hook is bored, a connection terminal for a power supply wiring is provided on one side of the mounting groove, and a connection terminal for a small force wiring is provided on the other side, Since the bulkhead plate disposed between both connection terminals can be easily attached and detached, the wiring work can be made easier by removing the bulkhead plate and performing wiring work, and then attaching the bulkhead plate after wiring. If the power supply wiring is low voltage wiring and does not require a partition plate, rational wiring can be achieved by removing the partition plate and bundling the wiring. In addition, the hook protruding from the upper end of the bulkhead plate is engaged with the engagement hole drilled on the top surface of the signal device body, and the side edge of the bulkhead plate is fitted into the mounting groove provided on the back side of the signal device body. Therefore, unless the partition plate is rotated upward, the partition plate will not come off and can be installed reliably.
