Description

  The present invention relates to an electronic device having an electronic block and a battery box that are applied to a lighting circuit for an emergency light or a guide light.

  The embedded type emergency light illuminator houses an emergency light block with a contact pin projecting on the lower end surface in the device main body, and a battery box having a receiving terminal on the side of the lower end in contact with the contact pin. (For example, refer to Patent Document 1). The embedded emergency light illuminator has a small bottom opening as the ceiling opening, so a vertically long emergency light block and a vertically long battery box are inserted into the relatively vertically long cylindrical body from the bottom surface. It is difficult to make a space for connecting between the wires, and when connecting the emergency light block and battery box from the bottom opening, the wiring connection work is performed while supporting the weight of the emergency light block and battery box. Since the work is not easy and it is necessary to consider safety, the emergency light block and the battery box are connected without wiring.

  On the other hand, in the case of an emergency light illuminating device or a guide light in which a thin box-shaped device main body with one side opened is directly attached to the ceiling or walled, as shown in FIGS. Therefore, when the flat electronic block 175 and the battery box 170 are mounted so as to be attached to the back of the storage space, the electronic block 175 in the stored state is stored. There was room to provide a wiring space between the battery box 170 and the battery box 170. Therefore, the battery box 170 houses the unit cell 172 in the battery case 171, and a connector 174 connected to the electric wire 173 connected to the unit cell 172 and a connector 77 connected to the electric wire 176 connected to the electronic block 175. The continuity was taken by connecting. Further, since the electronic block 175 and the battery box 170 can be accommodated in the horizontal direction from the side opening, the wiring work can be performed safely and easily.
