Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an earthquake detection electric light and radio device, and more particularly to the structure of a connecting terminal board that electrically connects a battery serving as a power source and a printed circuit board of a radio component.

In the past, when a relatively large earthquake occurred, there was a possibility of a power outage, and if this earthquake occurred just after sunset, people could panic because they could not find the whereabouts of their flashlights, candles, bells, etc. It is also necessary to obtain accurate earthquake information using a portable radio, but in the case of an emergency evacuation, there is usually not much time to search for its whereabouts. Furthermore, in electrical products using batteries, the battery serving as a power source, a terminal, and a terminal of the electrical product are connected by a lead wire, thereby forming an electrical circuit. However, the work of soldering these lead wires to the terminals of the battery and the terminals of the electrical product is extremely troublesome and requires a large number of man-hours. In addition, in the case of poor soldering, the solder may peel off during use and the device may no longer function as intended. Further, in the prior art, no electric light radio device suitable for such a case has been provided.

The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to provide an earthquake detection electric light and radio device in which a small lamp for detecting a relatively large earthquake lights up and at the same time the radio starts playing. Our goal is to provide the following. Another purpose is to create an earthquake detection electric light radio device that eliminates the need for lead wires and soldering work by electrically connecting the battery terminal and the conductor of the printed circuit board of the radio component with an integrally molded connection terminal board. The goal is to provide the following. Still another object is to facilitate the assembly work of the earthquake detection electric light radio device and to improve the connection strength of the connection terminal board.

In short, the present invention comprises a miniature light bulb, a radio, a battery mounting device, and an earthquake detection device, one end of which is connected and fixed to the conductor of the printed circuit board for the radio component, and the other end is integrally connected to the terminal of the battery. The present invention is characterized in that a formed connection terminal plate is provided.

The present invention will be explained below based on embodiments shown in the drawings. The device according to the present invention includes a main body 1, a miniature light bulb 2, a radio 3, a battery mounting device 4, and an earthquake detection device 5.
It is equipped with

The main body 1 is thin and spherical, and is divided into an upper body 1a and a lower body 1b at the center. The upper body 1a is made of an opaque but translucent material such as a milky white acrylic resin.
The lower body 1b is made of an opaque material, for example polypropylene. The miniature light bulb 2 is attached to a printed circuit board 7 which is a radio component fixed to the main body 1. A speaker 3a of the radio 3 is mounted on the bottom surface of the lower body 1b, and other radio components are arranged on a printed circuit board 7.

The main parts of the battery mounting device 4 include a battery mounting body 8 and a connecting terminal plate 9. The battery mounting body 8 is made of a thin elastic material such as synthetic resin, and is fixed to the lower body 1b. Further, battery holder portions 8a for accommodating batteries 11 are formed on the left and right sides of the battery mounting body 8. The battery holder part has a cylindrical shape and is divided into halves by going slightly around the center. Connection terminal board 9
are an upper horizontal piece 9a and a lower horizontal piece 9b that are parallel to each other.
and a connecting piece 9c that connects these horizontal pieces are integrally formed of a metal plate. The upper horizontal piece 9b is arranged so as to face the upper part of the left and right battery holder parts 8a, and the lower horizontal piece 9b is connected and fixed to the conductor of the printed circuit board 7 with a mounting screw 10. Two batteries 11 are elastically sandwiched and housed with different polarities between bamboo shoot springs 13 housed in the lower portions of left and right battery holder parts 8a and upper horizontal pieces 9a, respectively.

The earthquake detection device 5 is connected to a thyristor SCR via a cylindrical metal conductor 15 arranged on the lower surface of a printed circuit board 7 and connected and fixed to a conductor of the printed circuit board, and a resistor R (see FIG. 4). reference)
The main parts are a conductive wire 16 suspended below and a metal weight 17 fixed to the lower end of the conductive wire.
In a normal state, the weight 17 is suspended from the center of the conductor 15.

FIG. 4 is an electrical circuit diagram showing the wiring relationship of each part of the device according to the present invention. In the figure, SW ₁ is a miniature light bulb switch, SW ₂ is a radio power switch,
SCR is a thyristor, Tr is a transistor, B is a reset button, and R is a resistor of each part.

The present invention is constructed as described above, and its operation will be explained below. Since the terminals of the battery 11 and the conductors of the printed circuit board 7 are electrically connected by the integrally molded connection terminal plate 9, lead wires and soldering work are not required, and the number of assembly steps is significantly reduced. Further, since the lower horizontal piece 9b of the connector plate 9 is connected and fixed to the conductor of the printed circuit board 7 by the mounting screw 10, the assembly work of the earthquake detection electric light radio device is facilitated, and the connection strength of the connection terminal plate 9 is increased. Becomes large. Further, the battery 11 is accommodated in the battery holder part 8a, which is formed in half, by pushing the tip end of the battery holder part 8a outward. Therefore, the battery 11 is held down by the tip of the battery holder portion 8a and will not fall off from the battery holder portion during use. Further, the battery 11 housed in the battery holder portion 8a is held between the upper horizontal piece 9a and the elastic force of the bamboo shoot spring 13, so that the terminal of the battery 11 and the upper horizontal piece 9
There is no possibility of poor contact with a. Furthermore, as shown in FIG. 4, when the weight 17 is in the neutral position, that is, in the center of the conductor 15, no current flows through the miniature light bulb 2 and the radio 3 even if switches SW ₁ and SW ₂ are turned on. do not have. In this state, if a relatively large earthquake occurs and the weight 17 shakes with an amplitude above a certain level, the weight 17 will come into contact with the conductor 15 and the thyristor
A current flows through the gate of the SCR, a base voltage is applied to the base of the transistor Tr, the transistor becomes conductive, and the miniature light bulb 2 lights up, and at the same time the radio 3 starts to sound. This state will persist unless the reset button B is pressed to open the circuit. Then, when the reset button B is pressed, the circuit is opened and the miniature light bulb 2 and radio 3 go out at the same time. In this case, if you want to turn off only miniature light bulb 2, switch SW ₁
If you want to turn off only radio 3, just turn switch SW ₂ off.

In addition, in the case of a weak earthquake, the vibration amplitude of the weight 17 is small and the distance between the weight and the conductor 15 is large, so
The weight 17 does not come into contact with the conductor 15.

The present invention is constructed and operates as described above, so that when an earthquake is detected, a small light bulb lights up and the radio starts playing at the same time, so even if an earthquake occurs after sunset, the whereabouts of flashlights, candles, bells, etc. can be tracked. There is no need to search in a hurry, and in the event of an emergency evacuation, the effect is that earthquake information can be accurately obtained from the radio. In addition, since the battery terminal and the conductor of the printed circuit board of the radio component can be electrically connected using an integrally molded connection terminal board, there is no need for lead wires or soldering work, resulting in a significant reduction in assembly man-hours. is obtained. Moreover, this makes it possible to easily assemble the earthquake detection electric light and radio apparatus, and also has the effect that the connection strength of the connection terminal plate is greatly improved.
