AI Technical Summary
The challenge of protecting relay harnesses in electrical components housed in separate housings involves the difficulty in partially peeling off the sheath during manufacturing, leading to increased costs and size due to the need for relay harnesses and connection terminals.
The configuration of an electric working machine with a power supply housing, a first housing, and a second housing, where one end of the sheath is housed in the power supply housing and the other end in the first housing, allowing the second electric wire to be introduced into the second housing, thereby using a single sheath to supply power to both components without increasing the machine's size.
This configuration prevents the electric working machine from enlarging in size by utilizing a single sheath to supply power to multiple components, reducing the need for additional relay harnesses and connection terminals.

Abstract
Description
[Technical field]
[0001] The technology disclosed in this specification relates to an electric operating machine. [Background technology]
[0002] When electrical components are housed in separate housings, relay harnesses are required to connect the power source, control unit, etc. to each housing, and connection terminals are required to connect the harnesses to each other and the harnesses to electrical components. In addition, the relay harness needs to be protected from bending and from external forces when placed outside the housing, so a protective material such as a sheath is required around the harness, and a sheath cover such as a corrugated tube is required to prevent the protective material from being exposed to the outside. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2022-186580 A Summary of the Invention [Problem to be solved by the invention]
[0004] When a sheath is required to protect the harness, it is difficult to partially peel off the sheath in the middle of the harness during the manufacturing process of the relay harness. When a sheathed harness is used, the necessary portion is cut from the sheathed harness bundled on a reel, unnecessary sheaths at both ends of the cut harness are peeled off, and the exposed harness portion is processed. Since the above-mentioned processing is required, the sheath is not usually peeled off in the middle of the sheathed harness. Since it is difficult to partially peel off the sheath in the middle of the harness, a relay harness and a connection terminal are required between each housing. As a result, there are disadvantages such as increased costs due to the relay harness and the connection terminal, and an increase in size of the product due to the space required to accommodate the connection terminal.
[0005] The technology disclosed in this specification aims to prevent an increase in size of an electric operating machine. [Means for solving the problem]
[0006] This specification discloses an electric working machine. The electric working machine may include a power supply unit, a first electric component connected to the power supply unit by a first electric wire, a second electric component connected to the power supply unit by a second electric wire, a power source housing that accommodates the power supply unit, a first housing that accommodates the first electric component but not the second electric component, a second housing that accommodates the second electric component but not the first electric component, and a sheath that accommodates the first electric wire and the second electric wire. One end of the sheath may be accommodated in the power source housing, the other end of the sheath may be accommodated in the first housing, and the second electric wire drawn out from the sheath may be introduced into the second housing. Effect of the Invention
[0007] According to the above configuration, an increase in size of the electric operating machine is suppressed. [Brief description of the drawings]

The sheath 10F is disposed inside the pipe 18F.
[0110] As shown in FIG. 7, a grip 19F is provided at the rear of the power supply housing 7F. The switch 15F is disposed on the grip 19F. A grip 20F is provided at the front of the power supply housing 7F. The electric work machine 1F also includes a cleaning member 21F rotated by a motor 4F. The motor 4F is an inner rotor type DC brushless motor. As shown in FIG. 10, a rotor shaft 22F of the motor 4F protrudes downward from the motor 4F. The cleaning member 21F is connected to the rotor shaft 22F. As shown in FIG. 11, the light 6F is accommodated in the second housing 9F and is arranged to irradiate light from both the left and right sides of the first housing 8F.
[0111] In small scrubbers, which are often used in narrow areas, the cleaning surface is easily shaded by obstacles, so adding the light 6F can improve workability. The scrubber's tip vibration prevention mechanism makes it easier to work, especially when cleaning under chairs, desks, and shelves, because the head can be freely adjusted to change angle, but since the cleaning is done in dark places, it is desirable to brightly illuminate the floor surface on the left and right sides in front of the tip head. In this embodiment, the lights 6F are placed at two locations on the left and right of the tip of the Y-shaped arm (yoke) that connects the rod and the tip head, and the lights 6F are placed at positions and angles that can efficiently illuminate the floor surface in the front half of the head that is farther away from the operator's side within the arm angle of the working range (from 0° horizontally to about 60° vertically).
