Relay characteristic tester device and its protection box

Abstract

This utility model relates to the field of relay technology, specifically disclosing a relay characteristic tester device and its protective box, including a protective box and a protective cover movably connected to the opening of the protective box; fixed shafts are symmetrically inserted into the protective box; vertical plates are symmetrically sleeved on the fixed shafts; a movable plate is rotatably connected to the end of the vertical plate; a load-bearing plate is rotatably connected between the movable plates; a movable shaft is inserted between the movable plates; by fixing the relay characteristic tester to the load-bearing plate, and then, under the movable connection of the vertical plate and the movable plate, the characteristic tester and the load-bearing plate rotate around the end of the vertical plate under gravity and vibration, forming a motion space. Then, under the elastic deformation of the limiting block and elastic element connected between the fixed shaft and the movable shaft, the vibration external force acting on the movable plate and the movable shaft is absorbed, thereby protecting the characteristic tester and the load-bearing plate from violent up-and-down vibration and damage.
