Stamping fuse structure and manufacturing method thereof

Abstract

The invention relates to a stamping fuse structure and a manufacturing method thereof. The interior of a fuse is provided with a fuse line, the exterior of the fuse is covered with a protective layer and an insulating layer, and two ends of the insulating layer are provided with naked metal as electrode pins. The manufacturing method comprises the following steps: firstly, manufacturing the fuse line and electrodes on a first metal layer conductor substrate mainly using copper; secondly, adhering second metal layers consisting of silver, nickel, tin and the like and alloy thereof to the electrodes and the fuse line of the first metal layer; thirdly, manufacturing insulating layers with insulating and heat insulation effects at upside and underside of the middle fuse line of the metal substrate; and finally, cutting granules to obtain a finished product, wherein the insulating layers are made of high molecular materials such as silicon, epoxy and the like. Therefore, the method can carry out one-stop operation and quick production, and can effectively manufacture the stamping fuse with small volume, good function, convenience and practicability.

Description

technical field [0001] The invention relates to the innovation of the fuse structure and its manufacturing method, especially a pressure mode fuse structure with a simplified structure, small volume, easy manufacturing, low cost and wide application range and its manufacturing method. Background technique [0002] The popularity of power systems has brought convenience to human life, but because of the frequent fire accidents caused by improper use of electricity, the safety of electricity use has been paid special attention. Among them, the fuse plays a very important role in preventing electrical disasters, and its main function is to prevent excessive current from flowing through electronic circuits. The most important characteristic of a general fuse is its carrying capacity. The setting of the maximum carrying capacity of various types of fuses is a statistical value obtained through a series of tests, which can be used as a reference for circuit designers. When the exc...

Problems solved by technology

[0003] Most of the existing common fuse structures are packaged in glass tubes. There are metal shells on both sides of the tube, and metal wires are connected inside the two metal shells. It is also very inconvenient to install a fuse holder on the circuit board for its clamping

In addition, too large volume is also easy to form a space occupation, and manual plug-in is required for assembly, which is difficult to meet the actual needs of circuit boards in the technological era.
