A short-circuit discharge device for polypropylene film capacitor

Abstract

The invention discloses a short-circuit discharge device for polypropylene film capacitors, which includes a main body of the capacitor discharge device and a discharge pen. Both sides of the bottom end of the main body of the capacitor discharge device are fixedly connected with symmetrical limiting tubes. The inner bottom surface is fixedly connected with a bearing, and a rotating rod is arranged in the middle of the bearing, and a wire is wound on the surface of the rotating rod, and one end of the wire passes through the limiting tube, and the wire extends to the outside of the limiting tube, The electric wire is fixedly connected with the discharge pen, and the top of the limiting tube is provided with a knob; by installing the limiting tube, the length of the wire can be adjusted according to the actual use of the main body of the capacitive discharge device, and the use of the capacitive discharge device can be improved. The experience of the main body, the wires will not be entangled with each other due to the length being too long, which can save the time of untying the wires and improve work efficiency. .

Description

technical field [0001] The invention relates to the field of electrical accessories, in particular to a short-circuit discharge device for polypropylene film capacitors. Background technique [0002] Capacitor, the abbreviation of capacitor, is one of the electronic components widely used in electronic equipment. It is widely used in DC blocking, coupling, bypass, filtering, tuning loop, energy conversion, control circuit, etc.; Putting a little electricity directly on the circuit board will easily cause damage to the circuit board and cause unnecessary losses. Therefore, it is necessary to discharge the capacitor. In this process, a capacitor short-circuit discharge device is required. [0003] However, the wires of the existing capacitor short-circuit discharge device are too long and cannot be put away. During use, knots often occur, causing inconvenience, poor user experience, and even potential safety hazards. When the device is in use, it is not convenient to hold it,...
