Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

The structure of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, the embodiment of the present invention provides a novel surge protector, including: the device comprises a base 1, a grounding terminal 2, a protector 3, a live wire terminal 4, a zero line terminal 5, an indicator 6, a ring-shaped choke coil 7, a fuse 8, a zero line 9, a ground wire 10, a metal oxide varistor 11, a live wire 12, a buckle 13, a connecting plate 14 and a spring piece 15.

Example 1:

three protectors 3 are inserted in the middle of the base 1, an indicator 6 is embedded in the middle of the front face of each protector 3, a live wire terminal 4 and a null wire terminal 5 are fixedly installed on the upper surface of the base 1 through screws, and a grounding terminal 2 is fixedly installed below the base 1 through screws; the inside of the protector 3 is fixedly provided with a live wire 12, a zero wire 9 and a ground wire 10 which are respectively connected with a live wire terminal 4, a zero wire terminal 5 and a grounding terminal 2 on a surge protector base through welding, the live wire 12 is provided with an annular choke coil 11 and a fuse 8 through welding, and three metal oxide varistors 11 are arranged between the live wire 12 and the zero wire 9 through welding.
