Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuse technology, and more specifically, to a conductive connection structure for a fuse. Background Technology
[0002] Fuse, as a protective device, is commonly used to protect electronic components or electrical equipment in circuits. When the instantaneous current in a circuit exceeds a predetermined current rating, the fusible link in the fuse will melt due to the heat generated by the excessive current, thus breaking the circuit and preventing the overcurrent from flowing into the circuit, thereby protecting the circuit and electrical equipment from damage.
[0003] The existing patent publication number: CN112289655B discloses a fuse in which the fuse body 10 has connecting platforms 20 at both ends. The connecting platforms 20 are welded to the conductive connectors. However, the welding alone can cause the connecting platforms 20 of the fuse body 10 to become loose from the conductive connectors due to vibration or high temperature. Utility Model Content
[0004] The purpose of this utility model is to provide a conductive connection structure for a fuse, including a fuse element 10. Each end of the fuse element 10 has a connecting platform 20, and each connecting platform 20 is connected to a conductive connection structure. The conductive connection structure includes a connecting terminal 30 and a connecting piece 50. A connecting block 40 is provided between the connecting terminal 30 and the connecting piece 50. The connecting terminal 30, the connecting piece 50, and the connecting block 40 are integrally formed. The connecting piece 50 is wrapped around the outside of its corresponding connected platform 20. The fuse 50 is folded toward the end of the corresponding connecting platform 20 and clamped thereon. The connecting terminal 30 is bent away from the fuse 10 and connected to the circuit through the connecting terminal 30. When normal current flows through the fuse 10, the fuse 10 is intact and the circuit is unobstructed. When the current exceeds the rated value, the fuse 10 melts rapidly due to heat, cutting off the current and preventing the circuit or equipment from being damaged due to overload or short circuit. The conductive connection structure of the fuse ensures the safe operation and reliable connection of the fuse 10.
