Tool for adding alloy fusible core to fuse link

Abstract

The invention discloses a tool for adding an alloy fusible core to a fuse link, which comprises a fused liquid tank (1) with a liquid outlet nozzle (1.4), an air pump (2),a travel switch (3), a workbench (4), a slide bar (5) and a guide bar (6) for touching the travel switch (3), wherein an opening (1.1) and an air-suction inlet (1.2) are formed at the upper end of the fused liquid tank (1), a sealing cover (1.3) is arranged on the opening (1.1), the air-suction inlet (1.2) is communicated with the air pump (2), the fused liquid tank (1) is connected with the slide bar (5), a chute (7) matched with the slide bar (5) is arranged on the workbench (4), the lower end of the slide bar (5) is movably sleeved with the guide bar (6), a tension spring is arranged between the guide bar (6) and the workbench (4), a backing plate (10) is arranged on the workbench (4), and a pit (10.1) just opposite to the liquid outlet nozzle (1.4) is formed on the backing plate (10). The tool is convenient, efficient, and accurate.

Description

technical field [0001] The invention relates to a tool for adding an alloy melting core to a fuse link. Background technique [0002] The fuse link is an important part of the fuse. When the fuse link reaches the fusing temperature, it will be disconnected to protect the circuit. A plurality of dripping holes are arranged on the fuse piece, and the dripping holes are not limited to circular shapes, and may be in various shapes. After people add alloy materials such as tin-cadmium alloy materials to the drip hole, the fusing temperature of the fuse can be greatly reduced. The fusing temperature can be reduced to about 30°C. The alloy material particles added in the drip hole of the fuse link are the alloy melt core. Since the fuse link is very thin, the particles of the alloy core will protrude from the upper and lower surfaces of the fuse link. [0003] The device of the prior art for adding an alloy melting core to the fuse piece is very simple, and is only a melt tank f...

Problems solved by technology

There are many defects in this device: 1, people must manually tighten or unscrew the valve to realize the process of dripping or stopping the dripping, manual operation is cumbersome, time is needed for loosening and tightening the valve, the response speed of the device is slow, and the efficiency is low; 2, manual operation of the valve The response speed is slow, the accuracy is poor, and the amount of dripping liquid cannot be precisely controlled, resulting in inconsistent size and irregular shape of the formed alloy melting core, and poor yield of finished products
