Description

Power socket with double-pole double-throw switch

Technical Field

The invention relates to a power socket with a double-pole double-throw switch, belonging to the field of power sockets of power supply terminals.

Background

At present, with the increasing of electronic products, the situation that sockets are adopted as small electric appliances in construction sites, office places, families and other places is gradually increased, and a switching device on the existing socket only cuts off a single live wire, and meanwhile, due to the fact that construction is not standard, marks of zero and live wires are not clear, and the like, wrong connection is caused, and a zero line is cut off instead of the live wire, so that certain risks exist; meanwhile, the existing switch protrudes out of the socket, the switching on and off operations can be realized at will, and certain unpredictable risks are caused by the fact that the switch is started due to manual misoperation or external factors (such as factors of body touch and the like in falling and smashing of objects). Therefore, effective measures are required to be taken to realize the double-cut-off of the socket power supply and prevent the protection device of the double-cut switch from being accidentally closed; in addition, in the current common power distribution system, the master switch adopts the leakage protector, and according to the traditional mode of cutting off the live wire by a single switch, the power consumption appliance has no live wire and has no safety hazard to human bodies, but the zero line in the electric appliance is accidentally touched with the grounding protection wire, so that the leakage protector can act, the master switch is tripped, the power failure of the power distribution system occurs, and the normal work of other power consumption appliances is influenced.

The invention has the main innovation points that:

1. a power socket with a double-pole double-throw switch is developed, and the double-pole double-throw switch is used for simultaneously controlling the power of the power socket to be switched on and off.

In developing the above power socket having the double pole double throw switch, a protection device is disposed on the double pole double throw switch main body 400, and when the protection device is turned on, the double pole double throw switch main body 400 can perform operations of turning on and off a power supply; when the protection device is closed, the double pole double throw switch main body 400 can only perform the operation of cutting off the power supply, so as to cut off the power supply in an emergency and ensure the safety of power utilization.

3. In the above power socket with the double-pole double-throw switch, the double-pole double-throw switch main body 400 is provided with a clamping structure for the cover and the base of the protection device, so as to prevent the power socket from being opened artificially due to main body movement, wind power, gravity when the main body is downward and the like when the power socket is closed; a protection device is provided to prevent the double pole double throw switch body 400 from being operated by an accidental touch by having a cover higher than the double pole double throw switch body 400.
