preparation example Construction

[0056] The preparation method of fuse insulation protection cover of the present invention is;

[0057] Step 1. Prepare the wire leg fixing cylinder 1 and the connecting cylinder 2, and install the spring sheet in the installation groove 15 of the wire leg fixing cylinder 1, wherein the wire leg fixing cylinder 1 and the connecting cylinder 2 are made of high temperature resistant hard insulating material, preferably , the rigid insulating material is thermoplastic polyimide;

[0058] Step 2: Prepare the terminal 32 through a high temperature resistant hard insulating material, fix the spring leaf on the side wall of the terminal 32, prepare the sleeve core 31 through a high thermal conductivity insulating composite material, and place the two ends of the formed sleeve core 31 respectively After being sleeved on the terminal 32, the two are fixedly connected, and the fixed connection method is hot-melt connection, and the high-temperature-resistant hard insulating material is ...

Embodiment 2

[0071] The preparation method of the insulating layer is:

[0072] S1. Take sodium alkylbenzene sulfonate as a dispersant and add it to deionized water to dissolve, then add calcium fluoride to it, wait for the calcium fluoride to stir and disperse to obtain a calcium fluoride dispersion, and add polyethylene to the calcium fluoride dispersion alcohol, heated and stirred to obtain a viscous dispersion;

[0073] S2, using a coupling agent to treat the thermally conductive insulating particles, adding the treated thermally conductive insulating particles to the viscous dispersion obtained in the previous step, stirring and mixing, so that the thermally conductive insulating particles are uniformly dispersed in the viscous dispersion, and a thermally conductive filling material is obtained;

[0074] S3. Take the phenolic resin and polyvinyl chloride and heat and stir after uniform mixing. The phenolic resin and polyvinyl chloride are melted and mixed to obtain a mixed resin, wher...

Abstract

The invention discloses a fuse insulation protection sleeve, which comprises pin fixation cylinder, connecting cylinders and an insulation protection cover. The two ends of the insulation protection cover are connected with the pin fixation cylinders through the connecting cylinders respectively. When a fuse is installed, the fuse is arranged in the insulation protection cover, and independent pins at the two ends of the fuse are exposed; then, the connecting cylinders are clamped at the two ends of the insulation protection cover respectively, so that the position of the fuse is fixed; the two independent pins of the fuse are inserted into first pin through holes in the two fixation cylinders, and the end parts of the independent wire pins are clamped by a spring piece so as to be conducted with a circuit; in the whole fuse installation process, the fuse is connected to the circuit without a hinging and welding mode, and thus the fuse is convenient to install and replace; and a sleevecore is made of a high-heat-conductivity insulating composite material, and the high-heat-conductivity insulating composite material comprises a heat conduction layer and insulating layers arranged on the two faces of the heat conduction layer, wherein the insulating layers have good heat conduction capacity, heat resistance and electric insulativity.

Description

technical field [0001] The invention belongs to the technical field of fuses, and in particular relates to a fuse insulating protective sleeve and a preparation method thereof. Background technique [0002] A fuse is a circuit protection device installed on a wire circuit. When the circuit current exceeds the specified value, the heat generated by the fuse will blow the fuse of the fuse to ensure the safety of the circuit. Therefore, the fuse is circuit safe. important component. [0003] In the prior art, fuses are mainly installed and connected by welding, splicing, etc. Although the connection effect can be guaranteed, when the fuse needs to be replaced after the fuse is blown, the welding and splicing methods will lead to poor replacement. The problem of convenience, especially on some lines with unstable current and voltage, frequent replacement of fuses will be very cumbersome. In addition, in the prior art, the electrical contacts of the fuse are wrapped by rubber sl...
