Description
Technical Field
The utility model relates to a small isolating switch.
Background
The small isolating switch is one of low voltage switch electric appliances, and has isolating function in circuit. Because the electric appliance relates to different conditions of circuit on-off in use, the electric appliance forms a certain threat to personal safety, and the requirement on the working reliability of the electric appliance is high. The small isolating switch generally adopts a double-breakpoint structure, but the distance between two fixed contacts in the existing double-breakpoint structure is relatively short, and when the isolating switch is disconnected, short circuit is easy to occur between the fixed contacts, so that certain potential safety hazard exists.
Disclosure of Invention
In view of the above-mentioned shortcomings, the present utility model provides a small-sized isolating switch with phase-to-phase insulation.
In order to achieve the above purpose, the utility model adopts a small isolating switch, which comprises a shell, a fixed contact, a moving contact support and a handle, wherein the fixed contact is arranged at two ends in the shell, the moving contact is arranged in the moving contact support, the two ends of the moving contact extend out of the moving contact support to be opposite to the fixed contact, the handle is connected to the moving contact support to push the moving contact support to move up and down in the shell, the fixed contact is arranged below the moving contact, an upper insulating plate which extends downwards is formed at the lower end of the moving contact support, a lower insulating plate which extends upwards is formed at the inner wall of the bottom of the shell, and the upper insulating plate and the lower insulating plate are arranged in a staggered manner.
The utility model further provides that the bottom of the housing forms a venting port.
The utility model is further arranged that both ends of the gas leakage port are provided with lower insulating plates, and the upper insulating plates are arranged on the moving contact support above the gas leakage port.
The utility model is further arranged that the inner side of the fixed contact is provided with an arc striking pin which is connected with the inner end of the fixed contact and is bent outwards after extending downwards.
The movable contact support has the beneficial effects that the upper insulating plate is arranged between the fixed contacts, the lower insulating plate which is staggered with the upper insulating plate is arranged on the shell, and the upper insulating plate and the lower insulating plate are matched to separate the fixed contacts at two sides, so that the short circuit caused by electric arcs between the fixed contacts is prevented, the potential safety hazard is eliminated, and the safety performance is improved. The specific arrangement of the utility model is that 1 upper insulating plate and 2 lower insulating plates are arranged on two sides of the upper insulating plate, which is a preferred embodiment of the utility model.
