Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable fittings technology, specifically to a vibration-resistant copper lug. Background Technology
[0002] Copper lugs are a common connecting device in the electrical engineering field, mainly used for end treatment and connection of wires or cables. The most common way to connect copper lugs to cables is by mechanically pressing the tubular part of the lug tightly against the wire core, forming a low-resistance, high-strength connection. This method requires specialized crimping pliers, and if the connection is not secure during operation, a new lug must be replaced and reconnected to the cable, making it inconvenient and having a low tolerance for error. Furthermore, this type of connection only has one fixing structure, which may lead to cable loosening in certain special applications (such as when cables are frequently vibrated), increasing the frequency of maintenance.
