Description

Technical Field

[0001] This utility model belongs to the field of electrical technology, and specifically refers to an installation structure for an AC contactor. Background Technology

[0002] AC contactors play a crucial role in power systems, widely used in scenarios such as frequent starting and stopping of motors and remote control of circuits. The rationality of their installation structure directly affects the stability and reliability of the AC contactor during operation, and is related to the normal operation and ease of maintenance of the entire electrical system. A good installation structure ensures that the AC contactor maintains accurate positioning in complex working environments, guarantees the stability of its electrical connections, and also facilitates installation, maintenance, and replacement operations for installers.

[0003] However, existing AC contactor mounting structures present numerous problems. For example, some traditional mounting designs are rather simplistic, merely fixing the AC contactor directly to the mounting plate with bolts. This method is extremely inconvenient when disassembling and maintaining the AC contactor, requiring maintenance personnel to spend a significant amount of time removing and reinstalling the bolts. Furthermore, frequent bolt removal and installation can easily lead to wear on the mounting holes, affecting the stability of subsequent installations. Additionally, while some mounting structures employ specialized connection methods, under prolonged vibration, such as in industrial scenarios with frequent motor starts, poor structural design can cause the AC contactor to loosen, affecting its normal operation and potentially leading to electrical faults and unnecessary losses in the entire production process. Moreover, some mounting structures require complex calibration processes during installation, increasing installation difficulty and time costs, and reducing work efficiency. Utility Model Content
