Detailed Description
Referring to fig. 1-4, an intelligent fault arc detector comprises a detector body 1, a mounting groove 2, a first clamping tongue 3, a first circuit board 5, a connecting column 6 and a second circuit board 7, wherein the mounting groove 2 is embedded in the back surface of the detector body 1, the first clamping tongue 3 is welded on the left side and the right side of the top surface of the mounting groove 2, the first circuit board 5 is fixedly arranged in the detector body 1 through bolts, and the second circuit board 7 is fixedly arranged above the first circuit board 5 through the connecting column 6;
an anti-falling clamping mechanism 4 is arranged below the mounting groove 2.
The clamping mechanism 4 comprises a movable plate 401, a second clamping tongue 402, a buffer spring 403, vertical rods 404 and rubber balls 405, the second clamping tongue 402 is welded on the top surface of the movable plate 401, the buffer spring 403 is fixedly arranged on the bottom surface of the movable plate 401, the vertical rods 404 are welded on the left side surface and the right side surface of the bottom surface of the movable plate 401, and the rubber balls 405 are fixedly arranged on the bottom surface of the vertical rods 404.
In this embodiment, the cross-section of the movable plate 401 is in a shape of a letter "convex",
in this embodiment, the diameter of the rubber ball 405 is slightly larger than the diameter of the vertical rod 404.
Wherein, the embedding of the bottom surface central authorities of mounting groove 2 is provided with the sliding tray with fly leaf 401 adaptation, and the bottom of sliding tray both sides surface run through be provided with the through hole of montant 404 adaptation for fly leaf 401 joint can only reciprocate after in the sliding tray, and montant 404 runs through behind the through hole, and rubber ball 405 can prevent that the fly leaf from up putting and droing.
