In assembling the glass breakage detector, first, a plurality of chip circuit components 20 are surface-mounted on the three-dimensional circuit board 7 in advance to form a circuit block. Next, the piezoelectric sensor previously bonded and fixed at a predetermined position substantially at the center of the inner surface of the flat portion 8a of the metal base 8 is housed in the sensor housing recess of the three-dimensional circuit board 7. In this housing, the piezoelectric sensor is advanced from the opening of the sensor housing concave portion to the inside, and after the outer edge of the piezoelectric sensor is expanded by pressing the sensor holding spring piece 18 to the side, the outer edge of the piezoelectric sensor is attached to the sensor holding hook portion 18a. Is carried out. At this time, the positive and negative output terminals 1a of the piezoelectric sensor are in pressure contact with the sensor electrodes in the sensor accommodating recess to conduct. Next, like the piezoelectric sensor, the button battery is advanced from the opening of the battery storage recess 12 to the inside,
After the outer edge of the button battery presses the sensor holding spring piece 18 to the side to expand it, the battery holding hook 15a holds the outer edge of the button battery.

The operation of the glass breakage detector thus mounted will be described below. First, when the glass 5 is broken in order to enter the room through the window, the vibration of the glass 5 at the time of breaking the glass propagates to the piezoelectric sensor via the flat end of the metal base 8, and the piezoelectric sensor outputs a breaking signal which is a minute voltage signal.

Separate parts such as wires can be eliminated. Further, since the storage portion for storing and holding the battery 4 or the destruction detection sensor 1 is integrally formed when the three-dimensional molded article is formed, the component can be formed without forming the storage portion for the battery 4 or the destruction detection sensor 1 with other components. Can be reduced. Further, since an electrode for electrically connecting the battery 4 or the destruction detection sensor 1 to the signal processing circuit unit 3 is formed by extending the circuit pattern, the battery 4 or the destruction detection sensor 1 is formed by other components.
The number of components can be reduced without forming an electrode for electrically connecting to the signal processing circuit unit 3. In addition, since the case 6 has an electromagnetic shielding effect, the case 6 blocks external noise and prevents the signal processing circuit unit 3 from malfunctioning or being damaged by the external noise. Further, since the signal processing circuit portion 3 is provided in the circuit housing recess 22 provided integrally when the three-dimensional molded article is formed, the sealing material 21 for sealing the signal processing circuit portion 3 can be easily provided in the circuit housing recess 22.

It is hardly affected by noise in the processing circuit unit 3 and reaches an external alarm device clearly.

FIG. 6 is a circuit block diagram of a glass breakage detector different from the above according to the embodiment of the present invention. FIG.
FIG. 2 is a perspective view of a main part showing an attached state of the glass breakage detector according to the first embodiment.

As shown in FIGS. 6 and 7, this glass breakage detector is formed substantially in the same manner as the above-mentioned glass breakage detector. The difference is that the notification means 2 is connected to the sound source 23 and the light source 2
4 and the sound source 23 and the light source 24 are provided inside the case 6. Sound source 2
A piezoelectric buzzer is used as 3, and a light emitting diode is used as the light source 24. The well-known piezoelectric buzzer and light emitting diode are used, and each is electrically connected to the signal processing circuit, and the operation is controlled by the arithmetic processing unit 3d. Further, the piezoelectric buzzer and the light emitting diode are arranged between the lid cover 9 and the three-dimensional circuit board 7 and are fixed by appropriate means. In addition, a light transmitting hole 25 is formed at a position of the lid cover 9 facing the light emitting diode, and a sound transmitting hole 27 is formed at a position facing the piezoelectric buzzer.
The light emission and sound generation can be recognized on the indoor side 31 through 7.

In such a glass breakage detector, when a breakage signal is inputted, an intruder who breaks the glass 5 and tries to enter the room by using both the piezoelectric buzzer and the light emitting diode from a short distance. They threaten to prevent intruders.

Further, the light emitting diode is arranged between the metal base and the three-dimensional circuit board, and is used as a display lamp for displaying the operation of the signal processing circuit so that the presence of the signal processing circuit can be recognized from the outdoor side. You can also. In such a glass breakage detector, a display lamp for displaying the operation of the circuit unit informs a person outside the room of the existence of the glass breakage detector, thereby achieving a glass breaking action prevention effect.

Further, the light emitting diode can be made to emit light in response to a voltage drop when the battery is exhausted. In this case, it is possible to know an appropriate replacement time of the battery and to use the battery efficiently. In addition to being able to do so, non-operation due to battery exhaustion is prevented.

FIG. 9 is a circuit block diagram of a glass breakage detector different from the above embodiment according to the present invention. This glass breakage detector is formed substantially in the same manner as the above glass breakage detector. The difference is that a human body detection sensor 28 for detecting a human body located on the outer surface side of the glass 5 is provided inside, and the notification unit 2 can operate by a combination of both a human body detection signal of the human body detection sensor 28 and a destruction signal. That's what we did. An infrared sensor that detects infrared rays emitted from a human body is used as the human body detection sensor 28, and the notification unit 2 operates only when a person breaks the glass 5 and tries to enter the room. Needless to say, the case 6 has a built-in human body signal processing circuit 32 that receives the human body detection signal of the infrared sensor and inputs the signal to the arithmetic processing unit 3d.

In such a glass breakage detector, only when a person breaks the glass 5, both signals of the glass breakage sensor and the human body detection sensor 28 are input to the signal processing circuit unit 3 and notified. Thus, it is possible to distinguish and notify the destruction of the glass 5 due to a reason other than the intrusion of a person such as a malfunction of the glass break sensor and the destruction of the glass 5 due to the intrusion of a person.

FIG. 10 is a perspective view of a main part showing a mounting state of a glass breakage detector different from the above embodiment of the present invention. This glass breakage detector is formed substantially in the same manner as the above glass breakage detector. The difference is that a solar cell 26 having a storage capacity is used instead of the button cell.

The solar cell 26 is made of the glass 5 of the metal base 8.
It is provided over substantially the entire side surface, and is charged by receiving sunlight incident from outside the glass 5.

In such a glass breakage detector, since the solar cell 26 is charged by receiving the sunlight, it is not necessary to open the cover 9 and replace the battery 4 and to replace the battery 4.
This prevents a malfunction due to a delay in the replacement of the battery.
