Abstract

A communication adapter attachment device in one aspect of the present disclosure is provided in a working machine, and includes an adapter housing portion, a cap, and a cap-side interface. The cap-side interface is configured to enable viewing of the adapter-side interface and/or an input operation to the adapter-side interface from outside of the working machine, in a state in which the communication adapter is accommodated in the adapter housing portion and the opening is closed with the cap.

First claim

What is claimed is:

1. A communication adapter attachment device provided to a working machine, the device comprising:
an adapter housing portion provided inside the working machine, and having an opening on an outer surface of the working machine; and
a cap configured to close the opening,
the adapter housing portion being configured to accommodate a communication adapter that is detachable through the opening, the communication adapter including a protrusion on a side surface,
the cap being configured to be rotatable between a closed position and an open position about one end of the cap positioned in the closed position, the closed position being a position where the opening is closed, and the open position being a position where the opening is open,
the cap including an engaging portion, the engaging portion extending into the adapter housing portion and engaging with the protrusion in a state in which the cap is positioned in the closed position and when the communication adapter is accommodated in the adapter housing portion, and
the engaging portion being configured to move with the cap in engagement with the protrusion when the communication adapter is accommodated in the adapter housing portion, in case that the cap is rotated to the open position from the closed position, such that the communication adapter is moved from inside to outside of the adapter housing portion.

2. The communication adapter attachment device according to claim 1 ,
wherein the cap is provided with an elongated strap,
wherein the strap includes a fold-back portion at a distal end of the strap,
wherein the adapter housing portion has a strap insertion opening to which the strap can be inserted, and
wherein removal of the strap from the strap insertion opening, in case that the strap is inserted to the strap insertion opening, is restricted by the fold-back portion.

3. The communication adapter attachment device according to claim 1 ,
wherein the adapter housing portion includes a connector coupled to controller of the working machine, and
wherein the communication adapter is attached to the connector and is electrically coupled to the controller via the connector when the communication adapter is accommodated in the adapter housing portion.

4. The communication adapter attachment device according to claim 3 ,
wherein the connector includes a claw portion having a semicircular annular shape formed on a side surface of the connector,
wherein the communication adapter includes a connector engaging protrusion formed on a side surface of the communication adapter, and
wherein the claw portion is configured to engage the connector engaging protrusion when the communication adapter is attached to the connector, and to be elastically deformed to release engagement with the connector engaging protrusion in case that the engaging portion moves with the cap.

5. The communication adapter attachment device according to claim 1 ,
wherein the working machine is an electric working machine.

6. A working machine comprising:
a main body; and
a communication adapter attachment device,
the communication adapter attachment device including:
an adapter housing portion provided inside the main body, and having an opening on an outer surface of the main body; and
a cap configured to close the opening,

the adapter housing portion being configured to accommodate a communication adapter that is detachable through the opening, the communication adapter including a protrusion on a side surface,
the cap being configured to be rotatable between a closed position and an open position about one end of the cap positioned in the closed position, the closed position being a position where the opening is closed, and the open position being a position where the opening is open,
the cap including an engaging portion, the engaging portion extending into the adapter housing portion and engaging with the protrusion in a state in which the cap is positioned in the closed position and when the communication adapter is accommodated in the adapter housing portion, and
the engaging portion being configured to move with the cap in engagement with the protrusion when the communication adapter is accommodated in the adapter housing portion, in case that the cap is rotated to the open position from the closed position, such that the communication adapter is moved from inside to outside of the adapter housing portion.

7. A system comprising:
a working machine including a communication adapter attachment device; and
a communication adapter detachably attached to the communication adapter attachment device,
the communication adapter including a protrusion on a side surface,
the communication adapter attachment device including:
an adapter housing portion provided inside the working machine, and having an opening on an outer surface of the working machine; and
a cap configured to close the opening,

the adapter housing portion being configured to accommodate the communication adapter through the opening,
the cap being configured to be rotatable between a closed position and an open position about one end of the cap positioned in the closed position, the closed position being a position where the opening is closed, and the open position being a position where the opening is open,
the cap including an engaging portion, the engaging portion extending into the adapter housing portion and engaging with the protrusion in a state in which the cap is positioned in the closed position and when the communication adapter is accommodated in the adapter housing portion, and
the engaging portion being configured to move with the cap in engagement with the protrusion when the communication adapter is accommodated in the adapter housing portion, in case that the cap is rotated to the open position from the closed position, such that the communication adapter is moved from inside to outside of the adapter housing portion.
