In an embodiment, the external handle is detachably fixed to the external device.
When the external handle is damaged in the event of a failure, it is convenient to disassemble the external handle from the external device for maintenance and replace the external handle with a new external handle.
In an embodiment, the electrical apparatus further includes:
A detachable connection between the external handle and the external device is realized through the fastener, and is more stable and reliable.
In an embodiment, the external handle is fixed to the external device by bonding or welding.
The external handle and the external device are connected into an integrated structure, to prevent the external handle from falling off from the external device and enhance the stability and reliability of the connection between the external handle and the external device.
In an embodiment, the external device includes a first device and a second device arranged side by side, the number of the external handle is two, and the two external handles are symmetrically arranged on a side face of the first device and a side face of the second device.
By arranging the two external handles symmetrically on the external device, it is convenient for an operator to carry the electrical apparatus through the two external handles, thereby realizing a more convenient operation.
In an embodiment, a closed structure is enclosed by the external handle and the external device.
The operator holds the external handle in the closed structure without slipping out of the external handle, so that it is stable for holding the external handle and is stable and reliable for carrying the electrical apparatus.
In an embodiment, the external handle is U-shaped, and each of two side walls of the external handle is arranged on the external device.
The external handle is designed in a U-shape, which makes the structure simple and easy to realize, and ensures the closed structure enclosed by the external handle and the external device.
In an embodiment, an anti-skid rubber sleeve is sleeved on the external handle, and anti-skid is protrusions are provided on an outer surface of the anti-skid rubber sleeve. The friction between the operator and the external handle can be increased by the anti-skid protrusions, avoiding slipping on the external handle and ensuring that the operator holds the external handle more stably and reliably. In addition, the anti-skid rubber sleeve and the anti-skid protrusions on the outer surface of the anti-skid rubber sleeve have a certain degree of elasticity, which can avoid rigid contact between the operator and the external handle, increase the comfort of the operator when holding the external handle, and improve the protection for a hand of the operator.
In an embodiment, anti-skid threads are provided on a circumferential surface of the external handle.
The friction between the operator and the external handle is increased, avoiding slipping on the external handle, thereby ensuring that the operator holds the external handle more stably and reliably.
In an embodiment, the external handle is made of metal.
The external handle is made of metal, which can prevent deformation of the external handle and ensure the service life of the external handle.
In an embodiment, the electrical apparatus is an inverter, and the external device is a radiator or a reactor.
The beneficial effects of the present application are as follows:
The electrical apparatus is provided according to the present application. The electrical apparatus includes the box, the external device and the external handle. The external device is fixed on the outer side of the box, and the external handle is arranged on the external device. The external handle is configured for carrying of the electrical apparatus. By arranging the external handle on the external device, the external handle does not occupy additional space of the box, which reduces the occupation of the area of the box after the external handle is mounted, realizes a small box and reduces the cost of the box, thereby reducing the cost of the entire electrical apparatus and improving the market competitiveness of the entire electrical apparatus.
