Dual-voltage dual-power single-phase bipolar security socket

Abstract

The invention discloses a dual-voltage dual-power single-phase bipolar security socket which comprises a panel, a push plate, two L pole protecting doors, two L pole plug bushes, an N pole plug bush, a base, a transformer, an L pole binding post, an N pole binding post, an E pole binding post, a gland and a double-break plug-in safety switch. Compared with the prior art, the invention has the following advantages: 1, by taking the dual safety protection measures of splash-proof electric-shock-proof protecting doors and safety switch, the safety is enhanced; 2,in the invention, the heavy-current double-break structured safety switch is adopted, and the moving contact plate is riveted with moving contacts, thereby enhancing the safety, increasing the current capacity and ensuring that the switch can bear 10A current; and 3, the invention improves the circuit design, so that the 110V plug bush takes power from the secondary level of the transformer and the 220V plug bush directly takes power from the external power supply, thereby increasing the current capacity of the 220V plug bush, and thus, the 220V plug bush can be used for 220V high-power electric appliances, such as hair driers and the like.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a socket, in particular to a safety socket with dual-voltage and dual-power usage functions. Background technique [0002] Shaver sockets must be installed in hotel bathrooms. In order to take into account the voltage standards of different countries and regions, the razor sockets installed in all hotels at home and abroad now have dual voltage (110V and 220V) functions, which is convenient for shaving products produced in different countries. Knives use, as disclosed in Chinese invention patent CN1421960A "specially used for electric razors, with an independent retractable electric current socket". In this patent, the 110V and 220V sockets are powered by the secondary of the transformer. Because the volume of the transformer is small, the diameter of the coil of the transformer is relatively small, so it cannot provide a large current; The contact resistance bet...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the existing dual-voltage socket can only be used for razors only, and aims to provide a type that can be used not only for razors, but also for high-power appliances such as hair dryers. electrical socket

[0005] The present invention also solves the problem that the single-piece single-open protective door has a relatively large pushing force and pushing stroke in the existing dual-voltage socket, and aims to provide a protective door with waterproof splash and electric shock protection and plug-in and pull-out Dual Voltage Dual Power Dual Safety Protected Outlet with Off Safety Switch
