Embodiment 1

[0028] Such as Figure 1-5 As shown, the embodiment of the present invention provides a main circuit safety plug, which includes an outer casing 6, and two inner frames 7 are arranged in the outer casing 6, and the two inner frames 7 are the same in size and shape, and are set up oppositely. The bottom surface of the inner frame 7 is fixed with Spring steel sheet 2, and two spring steel sheets 2 have the same size and shape, and are relatively established. The inner wall of the inner frame 7 is provided with two circular grooves of the same size, and the grooves are blind grooves. The two grooves of the inner frame 7 The first elastic piece 4 and the second elastic piece 5 are respectively arranged in the groove, and the side of the first elastic piece 4 and the second elastic piece 5 away from the inner frame 7 is against the side of the positioning bracket 3, and the positioning needle 8 is nested around the inner frame 7. , and the positioning needle 8 is slidably connected...

Abstract

The invention provides a main circuit safety plug, and relates to the technical field of electrical equipment. The main circuit safety plug comprises an outer sleeve, and two inner frames are arrangedin the outer sleeve; the two inner frames are the same in size and shape and are arranged oppositely, and a positioning bracket is arranged in each of the two inner frames; the positioning brackets are in sliding connection with the inner frames; two pin copper sheets are arranged between the two inner frames; and the pin copper sheets are in sliding connection with the inner frames. According tothe invention, a spring steel sheet is designed, the pin copper sheets are protected, and the pin copper sheets can be tightly fixed in the socket and cannot easily slip so as to ensure the power utilization safety; and moreover, the punched copper sheet is uniform in thickness, flat and smooth in transition and free of burrs, the safety problem of the plug caused by surge is avoided to a certainextent, the surface of the copper bar is tinned, the plating layer is good, the phenomenon that the plug pins are blackened is avoided, the plug pins are riveted symmetrically, the socket is coated with a proper amount of electric force compound grease, and the plug pins are not prone to dislocation.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a main circuit safety plug. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards have also improved, and various electrical equipment have gradually become common tools for people's daily leisure and work, and the use of electrical equipment requires electricity, plugs And socket is a kind of electrical equipment commonly used in people's daily life and work, when using electricity, plug is inserted in the jack of socket, after using up, then plug is pulled out from socket and gets final product, comparatively easy. Especially in the construction sites of some construction sites, carpenters, welders, steel workers, concrete workers, etc. all need electricity when using the required construction tools. Their electricity consumption time is not uniform. When they need electricity, they al...
