Protective tube with anti-explosion structure

Abstract

The invention discloses a protective tube with an anti-explosion structure, which comprises a glass tube, two ends of the glass tube are connected with dismounting sleeves through mounting mechanisms, conductive plates are fixedly connected in the side walls of the middle parts of the sides, far away from the glass tube, of the dismounting sleeves, pressure relief mechanisms are mounted in the dismounting sleeves, and the pressure relief mechanisms are connected with the mounting mechanisms on the same side. Through holes are formed in the side walls of the sides, away from the glass tube, of the upper ends, the lower ends, the front sides and the rear sides of the disassembling and assembling sleeves, and dustproof mechanisms are jointly installed on the outer sides of the multiple through holes in each disassembling and assembling sleeve. The pressure relief mechanisms are mounted in the dismounting sleeves, when the air pressure in the glass tube is increased, the pressure extrudes the sealing plates of the two pressure relief mechanisms to be extruded out of the through grooves where the sealing plates are located, then the glass tube is communicated with the outside through the through holes in the dismounting sleeves, the pressure is released, and the situation that the glass tube bursts is avoided.

Description

technical field [0001] The invention relates to a fuse, in particular to a fuse with a burst-proof structure, and belongs to the technical field of fuses. Background technique [0002] The fuse tube generally refers to the fuse tube, and the fuse tube refers to an electrical component installed in the circuit to ensure the safe operation of the circuit. The fuse tube is made of lead-tin alloy or lead-antimony alloy material, which has the characteristics of low melting point, high resistivity and fast fusing speed. [0003] When the currently used fuse is in use, the glass tube of the fuse is very likely to burst due to the increase in internal pressure, which will cause the parts where the fuse is installed to be covered with glass tube fragments, and it will be more troublesome for the staff to clean up , and the electrodes at both ends of the fuse are mostly fixed on the glass tube. When the glass tube of the fuse is accidentally damaged or the fuse breaks, the fuse need...

[0003] When the currently used fuse is in use, the glass tube of the fuse is very likely to burst due to the increase in internal pressure, which will cause the parts where the fuse is installed to be covered with glass tube fragments, and it will be more troublesome for the staff to clean up , and the electrodes at both ends of the fuse are mostly fixed on the glass tube. When the glass tube of the fuse is accidentally damaged or the fuse breaks, the fuse needs to be replaced as a whole, which is uneconomical
