Description

Technical Field

[0001] The present application relates to the technical field of fuse processing, and in particular to a fuse processing device. Background Art

[0002] A fuse is a current protector made based on the principle that "when the current exceeds the specified value for a period of time, the heat generated by the fuse melts the fuse and disconnects the circuit." Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, they are one of the most commonly used protective devices.

[0003] In the related art, the fuse, as a key component of circuit protection, usually includes an insulating shell and a sheet-shaped fuse inside the insulating shell. Terminals are fixed on the upper and lower sides of the insulating shell. In order to improve the arc extinguishing performance of the fuse, a sand filling hole for quartz sand injection is opened on the upper surface of the insulating shell so as to fill quartz sand between adjacent fuses. After the sand filling is completed, the sand filling hole will be sealed with a cap to ensure the integrity of the fuse.

[0004] However, in the performance testing phase after the fuse is filled with sand, the traditional testing method requires staff to manually place the sand-filled fuse on a special testing table and use specific testing tools to detect the resistance value of the fuse. The manual transfer of the fuse consumes extra time, which is not conducive to the rapid testing needs of large-scale production, and there is room for improvement. Summary of the invention

[0014] By adopting the above technical solution, in the process of the adjustment rod closest to the base pushing the fuse, due to the setting of the buffer pad, the compression spring and the buffer protrusion, the buffer pad abuts against the outer side of the fuse, and when the adjustment rod passes through the elastic buffer, the abutment block on the adjustment rod will squeeze the protruding part of the buffer protrusion to shrink it into the placement groove, thereby adjusting the pushing force of the adjustment rod on the fuse, reducing the possibility of the fuse loosening or even detaching when passing through the connecting inclined plate, and making it more stable when pushed.

[0015] Optionally, a vibration source for driving the receiving plate to vibrate is provided on the base.

[0016] By adopting the above technical solution, when the quartz sand in the sand storage box is poured into the inside of the fuse through the sand filling hole on the fuse through the sand injection pipe and overflows, excess quartz sand will accumulate on the upper surface of the fuse. At this time, the receiving plate is driven to vibrate by the vibration source, which can not only make the quartz sand on the surface of the fuse slide off, but also compact the quartz sand that has been poured into the fuse, thereby improving the sand filling effect in the fuse.
