Abstract
An interlocking adapter in one aspect of the present disclosure includes a current path, an electric load, a switch, and a controller. The controller turns on and off the switch in synchronization with a change of an alternating-current voltage received from an electric outlet of an electric apparatus in response to reception of an interlocking command signal from a working machine so as to supply a load current from the electric outlet to the electric load. The controller turns on and off the switch at a specified ratio of a time every ½ cycle of the alternating-current voltage.
Claims16
An interlocking adapter comprising:
- a plug configured to be plugged into an electric outlet in an electric apparatus;
- a first input path and a second input path configured to receive an alternating-current voltage from the plug;
- a capacitive load on the first input path;
- a full-wave rectifier including a first alternating-current input, a second alternating-current input, a first direct-current output, and a second direct-current output, the first alternating-current input being coupled to the first input path through the capacitive load, the second alternating-current input being coupled to the second input path, and the full-wave rectifier being configured (i) to rectify a full wave of the alternating-current voltage received via the first alternating-current input and the second alternating-current input and (ii) to thereby generate a rectified voltage between the first direct-current output and the second direct-current output;
- a switch electrically coupled to the first direct-current output and to the second direct-current output, the switch being configured to be switched between an on-state and an off-state, the switch in the on-state being configured to complete a current flow path between the first direct-current output and the second direct-current output through the switch, and the switch in the off-state being configured to interrupt the current flow path;
- and
- a reception input circuit configured to receive an interlocking command signal via a receiver, the interlocking command signal being wirelessly transmitted from a working machine, the receiver being configured (i) to wirelessly receive the interlocking command signal and (ii) to convert the interlocking command signal received, into light, the reception input circuit including a light receiving device configured (i) to be applied with a direct-current voltage and (ii) to receive the light to thereby turn on, and the reception input circuit being configured to turn on the switch in response to the light receiving device turning on or having turned on.
