Description

  The present invention relates to a housing of an electronic device. In particular, the present invention relates to an electronic device casing that can be used by connecting a plurality of electronic devices.

  In an electronic device for information transmission such as a security system or a destination display board, not only a single electronic device is used alone, but also a plurality of electronic devices may be connected and used. Even if the information transmission capability is insufficient due to the single use of one electronic device, the information transmission capability of the entire electronic device can be enhanced by electrically connecting and using a plurality of electronic devices.

  Some electronic device casings that are used by connecting a plurality of electronic devices are provided with a cable passage for passing an electric cable. Furthermore, some electronic device casings include a lid member that can close the cable passage and is detachable from the cable passage.

  When the electronic device is used alone, the deterioration of the appearance quality of the electronic device can be suppressed by closing the cable passage with the lid member. When a plurality of electronic devices are connected and used, the plurality of electronic devices can be easily electrically connected by removing the lid member from the cable passage and passing the electric cable through the cable passage. In this case, since the electric cables can be easily arranged, the appearance of the electronic device in the connected state can be improved.

  However, conventionally, a connecting member for connecting a plurality of electronic devices and a lid member have been separately required. For this reason, the number of parts constituting the electronic device has increased and the cost has increased. In addition, parts that are not used, that is, a connecting member when an electronic device is used alone or a lid member when a plurality of electronic devices are connected and used may be lost. . Therefore, a structure of a connecting device that can also use the lid member as a connecting member has been proposed (for example, Patent Document 1). By using the lid member also as the connecting member, the number of parts constituting the electronic device can be reduced, an increase in cost can be suppressed, and loss of parts can be prevented.
