Leakage protector

Abstract

The invention relates to a leakage protector which comprises a base, a cover body and a tripping mechanism. The tripping mechanism comprises a support, a coil frame, a positioning shaft, a handle, a jumping pin, a tripping component, two movable contacts on the base, static contacts which are arranged on the base and correspond to the contact ends of the movable contacts, and a contact frame device which is arranged in a mounting groove of the base and can drive the two movable contacts to move. The tripping component comprises a re-trip part and a lock catch which is linkage fit with the re-trip part, a spring is arranged between the re-trip part and the lock catch, the re-trip part is arranged at the lower end of the handle, and is in linkage fit with the handle, and a corresponding limiting groove is formed in the fit end of the jumping pin and the lock catch. An iron core is arranged on the coil frame, a coil is arranged on the iron core, one end of the iron core is fixed to one side of the jumping pin, and the iron core can drive the jumping pin to rotate around the positioning shaft. The protector has the advantages of being simple and compact in structure, and having the high sensitivity and rapid motion in reaction electric shock and leakage protection.

Description

technical field [0001] The invention relates to the field of leakage protection, in particular to a leakage protector. Background technique [0002] At present, the existing domestic building electrical connections are mostly connected by sockets, that is, the sockets are plugged into the conduction work. This kind of structural design is basically limited to the use of the current range below 16A, but in actual life, most of them exceed For the load equipment required by this current range, since there is a lack of wire-type leakage protection sockets exceeding the current range of 16A or more on the market, only wire-type leakage protection sockets below 16A can be used instead, but it is very easy to overload and cause electrical accidents. , resulting in personal safety accidents and economic losses. Therefore, the market is in urgent need of a wiring type leakage protector for buildings with a current range above 16A. Leakage protectors are mainly used to quickly cut ...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing leakage protection switches are embedded and installed in the junction box on the wall

The existing junction box is 86-type box, but in practical applications, sometimes there are different types of box, for example, 120-type, 118-type box, but the existing leakage protector is difficult to install, only one type can be installed It is still very inconvenient to change the installation even if the accessories are added, and at the same time increase the cost of the accessories

Moreover, the existing leakage protector cannot guarantee the accuracy of the tripping time when a leakage fault occurs and a person with fatal danger gets an electric shock due to the uncompact design of its tripping mechanism, and the tripping mechanism occupies The space is also relatively large
