Description

Technical Field

[0001] The utility model belongs to the technical field of fuse assembly, and in particular relates to a pin trimming device for fuse assembly. Background Art

[0002] A fuse, also known as a current fuse, is defined as a fuse-link by the IEC 127 standard. Its primary function is overload protection. When properly placed in a circuit, the fuse will melt when the current rises abnormally high or reaches a certain temperature, shutting off the current and ensuring safe circuit operation.

[0003] Publication (Announcement) No.: CN215199454U, discloses a pin trimming device for capacitor production, wherein a second improved pin trimming structure is connected to a first connection hole on one side of the workbench, and a first improved pin trimming structure is connected to a first connection hole on the other side of the workbench. The first improved pin trimming structure also includes a connecting strip and a second connection hole, and a connecting strip is provided at the lower end of the pin placement knife table. The utility model is a pin trimming device for capacitor production, which belongs to the field of capacitor pin trimming equipment. The improved pin trimming structures on both sides of the capacitor package support frame can trim two pins of the capacitor, without trimming one pin and then switching the capacitor to trim the other pin, which is convenient for the staff to operate and avoids the inconvenience caused by the staff switching and the capacitor falling out of the hands. The arc-shaped slide facilitates material discharge, and the improved pin trimming structure can be adjusted according to actual needs, thereby adjusting the trimming length of the capacitor pin.

[0004] The existing technology has the following problems: during the installation process of the current fuse, the length of the pin does not match the circuit, so the two ends of the fuse need to be manually trimmed. On the one hand, the trimmed lengths are uneven, and on the other hand, trimming the two ends is easy to waste time. In addition, due to different equipment, when the two ends of the fuse need to be bent, the fuse pins are too small, which causes inconvenience. Therefore, we propose a pin trimming device for fuse assembly. Utility Model Content
